The invention relates to a connecting element for connection globcover sections of the chain scraper conveyor or guide sections of the mining machine, in particular guide the plane containing the two United in one piece by narrowing the width of the rod head, which are directed to the rod side of the supplied angle to the rod shoulder. In addition, the invention concerns a connection node of the corresponding coupling element located on the sections of the pockets for the coupling element, in which gap may be placed in the connecting element containing United in one piece by means of a rod head, and pockets for the coupling element are inclined thrust surface for engagement with a shoulder on the heads of the coupling element.

In the underground mining industry is known for numerous run of the connecting element and the connection node globcover sections of the chain scraper conveyor or guide sections of the mining machine. In practice, mining is well established, in particular, the nodes of the connection, in which the coupling element in the axial continuation of the rod contains both heads of the locking lugs, connection status, covering the back pikirayi the surface in pockets for the coupling element and is protected from falling out of open side pockets connecting elements. The locking surface in the pockets for the connecting element may consist of still located in the pockets shut jumpers or detachable locking elements.

From DE 3645321 C2 are known corresponding to the generic concept of the connecting element, which is supplied to one cylinder cryoablate made locking Cam, and the other head has a wider rectangular locking Cam. One pocket for the coupling element provided on the opposite connecting the junction of the rear end is made in the form of undercut pocket, which includes a locking hook, and the other pocket is open at the rear end and goes into approximately rectangular profile of the hole pockets. The wider the locking lug in the installation position is in the intermediate area between the pocket and the core hole and is fixed there by means formed of a plate of the rotary latch, which scroogle at both ends of the plate. One end of the plate in the mounting position is located in the recess, made recourse to lying seam side pockets. The other end plate Rethimno secured by a clamping sleeve on the ledges of the walls, which are made from the hanging layer on the side wall of the pocket and have holes for clogging clamp the second sleeve. Over his broader locking latch head connection element has a groove, so that even in the event of axial movement of the connecting element on the rotary latch could not be transferred to the efforts and prevented accidental disconnection of the rotary latch. Bottom hook of the locking protrusion is wedge-shaped tapering towards its upper side, so that the connecting element can be obliquely placed in the pocket, and then turned down. The bottom pockets for both the coupling element is completely flat. Additionally shouldered on the heads of the coupling element and the thrust surface in the pockets are straight line inclined to the longitudinal axis of the rod, and the connecting element adjacent its shoulder without pagnutti to hard surfaces.

From DE 10011288 A1 known connection element and the connection node for globcover and guide sections, in which the two balanced each other out of pocket for the coupling element placed on adjacent to each other the ends of the sections, and the connecting element contains made symmetrically to each other in the head with locking tabs. The locking tabs projecting from the heads of the connecting element with significantly less compared to the thickness of the heads of the connecting element, approximately constantly the thickness. The upper and lower side of the clamping tongues are plane-parallel to each other, and the connecting element is fixed from the side drop provided by both fixing reeds detachable safety clips in his pockets. Each safety latch has two deformable clamping sleeves that can be introduced in a semi-circular notches on opposite edges of the walls of both longitudinal sides of the pocket to the coupling element. Due to the symmetric perform as pockets for the coupling element and the coupling element and the safety element, can be avoided when mounting problems with orientation. Shouldered and hard surfaces are also inclined to the longitudinal axis of the rod coupling element or respectively pockets for him and made in the form of a flat wedge surfaces.

In the underground mining industry fasteners and pockets for them exposed to high loads. The heads of the connecting elements must absorb all axial forces between adjacent Gelashvili or guide sections, which arise due to moving with the change of direction of the mining machine and/or moving scrapers scraper chain conveyor. At the same time, the connective cell battery (included) what you and pockets for them must provide sufficient angular mobility of neighboring globcover sections, as should be compensated folds and hollows lying layer, and the shifting of the chain scraper conveyor or guide for the mining machine may only be carried out section by section.

The objective of the invention is the creation of the coupling element and the connection node with which it could transmit high axial forces at higher angular mobility and simpler installation connecting elements.

This task in relation to the coupling element is solved due to the fact that shouldered made convex, in particular kruglosutochnyj. Due to the convex execution shoulders, and the resulting point or line contact surface between the shoulder on the heads of the coupling element and the respective thrust surfaces in the pockets for the coupling element improves vertical mobility neighboring globcover sections to compensate for losses or recumbent folds of the bed while simultaneously optimized perception axial tensile load in the heads of the connecting element. When using under ground because of a certain perception of transmitted effort between the shoulder and thrust surfaces are prevented from contact voltage.

In the preferred embodiment, as in itself Izv the STN, both heads of the connecting element provided on facing away from the rod end of the head axially projecting locking tongue, tapering in cross section or thickness relative to the head and/or head of the connecting element, shouldered and the locking tabs are made symmetrical relative to the middle rod. Improper installation of the coupling element due to incorrect installation of the connecting element in the pockets prevented by symmetric implementation, due to the design. In a preferred embodiment, the radius of curvature of the end head on the land side from the locking tongues may be the same size, or smaller than the radius of curvature of the shoulder. The radius of curvature of the section of the end of the head above the locking tongue may also be different from the radius of curvature plots on the side of the locking tongue and may be the same or mostly the same in magnitude as the radius of curvature of the shoulder. Due to the smaller radius of curvature of the end head to one side from the locking tongues even when the maximum vertical bending adjacent globcover sections loosen tension on the end of the head.

Additionally, the outer side surfaces of the heads of the connecting element can be made mostly flat and plane-parallel cf the days of the longitudinal plane of the connecting element. Convex or rounded fillet shoulder can pass from the rod to the side surfaces of constant radius or curvature and/or rounding of the ends of the heads are held constant radius fillets through the area above and to the side fixing sections of the reeds.

In a particularly preferred embodiment, the head of the connecting element, at least on the lower side and/or on the upper side is made curved, for example rounded width, i.e. from one side surface to another. While the corner radii of the lower and upper sides of the heads of the connecting element can be, in particular, is also equal to the radius of rounding of the shoulders. Due fillets heads across the width of additionally improving vertical and horizontal mobility of neighboring grooves or guides sections. The radius of rounding of the shoulders, and/or areas may be preferably less than the distance between the side surfaces of the heads of the connecting element and is greater than the maximum depth of the rod and the maximum depth of the heads of the connecting element.

For mounting corresponding to the invention connecting elements, preferably, if the locking tabs wedge-shaped taper towards their ends on the upper and lower sides. The top and bottom sides of the fix is their reeds can be made essentially flat, respectively, over the entire width. In addition, the rod coupling element preferably may have an oval cross-section and/or provided in the middle of the rod forming the place specified in the destruction of the constriction, so that even when excessive loads of connections, it is possible to prevent damage to globcover sections or fixed on them pockets for the coupling element at the expense of a specified fracture of the connecting element.

Corresponding to the invention the connection node differs in that shouldered made convex, in particular convex rounded and resistant surface, at least in the area of the contact zone with the shoulder - flat or, if necessary, only slightly convex. Especially beneficial if the pockets corresponding to the invention of the node connections are done differently in relation to each other, one of the two pockets to the coupling element fitted primetim and partially covering the top of the hole pocket locking tab on the back pocket, so that by locking ledge formed by the undercut to accommodate the locking tabs on the respective head of the connecting element. For mounting the connecting element is particularly preferred if the bottom has a locking tab pocket for the coupling element provided with a recess, typically the military held inclined and increasing with increasing distance from the interface, so one of the two locking tongues when mounting or Dismounting could enter into the groove. In coordination with the inclined lower side of the locking tongue when mounting the connecting element can be inserted one head with one hand at the bottom of the pocket, and then turned.

Additionally, the depth of the bottom of both pockets preferably may increase from the rear side of the pocket to the front side at the junction between two adjacent pockets, preferably the bottom of both pockets made grooved. The locking protrusion preferably has a member in the pocket of the front side of the groove, preferably a groove with a base in the shape of an arc of a circle, for optimum angular mobility rounded on the end heads of the connecting element relative to the locking tabs. Another pocket preferably has on the rear side of the through hole to the second recess of the pocket, in which, with the possibility of separation and fixation installed integral locking device connecting element for fixing the second retainer tab.

For this purpose, the locking device is mostly fills the recess of the pocket in the axial direction completely, in order to prevent axial displacement of the head of the connecting element in the direction of the through hole. The issue is the implementation of both pockets, which can be pririty to globcover or guide sections or welded as separate parts, can be independent of fasteners own inventive value.

The invention is explained in more detail with reference to the example of execution shown in the drawings, which represent:

figure 1 is provided with a connecting element and corresponding to the invention the connection node on the side pockets for the coupling element;

figure 2 - section of the pockets of figure 1 in side view of a connecting element;

1 and 2 represent the entire node 100 to connect together with the tensile strength and the angular mobility globcover sections of the chain scraper conveyor or guide sections for underground mining machine (not shown). The node 100 connection includes the first 1 and second 2 pockets to the coupling element, which are either welded or directly pririty to the appropriate partitions. Each pocket 1, 2 forms, respectively, for one of the halves of the coupling element 10 socket 3 or 4, which has a conically reduce the clinical from the front side 5 or 6 pocket receiving area for the rod, rolling in the receiving section 7 or 8 for the head. Both receiving section 7, 8 for the heads are held inclined to the other pocket 2, 1 hard surfaces 21, 22, made straight flat or slightly convex-curved. To hard surfaces 21, 22 of pockets 1, 2 of the connecting element 10 adjacent the shoulder 11, which are respectively directed to the terminal 12 side of the United them heads 13 of the connecting element. Shouldered 11 both heads 13 are obliquely to the rod 12 and a convex is formed in the form of a circular arc surface. The receiving slot 3, 4 for the connecting element is made identical to each other in terms of hard surfaces 21, 22 and the receiving slots of the rod, and the head 13 of the connecting element are guided respectively by the two shoulder 11 on both sides of the rod 12 on the respective thrust surfaces 21, 22.

The connecting element 10 has at each head 13 of the locking lug 14, the wedge-shaped tapering towards its end 15, with the top 14' and the bottom 14" side fixing tongue is made flat, inclined to the horizontal plane and converge to each other, so that the locking lug 14 is wedge-shaped tapering towards its end 15. The connecting element 10 is fixed by the locking tongues 14 in the open sides of karmas is nah 1, 2 using the appropriate fixing elements. Corresponding to the invention, the node 100 connection includes one still embedded in one of the pockets of the retainer element and one detachable fixing element. Fixed locking element consists of a locking protrusion 23, which is made in one piece with the rear side of the socket 4 of the pocket 2 and grooved on its part of the socket 8 for the head of the connecting element to the front side 24, in order to maintain low contact stress between the respective end 16 of the head 13 and the locking protrusion 23, and also to facilitate the movement of the head of the connecting element like a ball joint. Under the locking projection 23 of the pocket 2 has a through groove 25, the bottom plot 25' in which a groove obliquely narrowed down to the attached zhelobkovoi or guide section. Bottom plot 25' runs essentially parallel to the bottom side 23' of the locking protrusion, so that the connecting element 10 during Assembly can be placed obliquely in the pocket 2 and to thus locking tongue 14 could relatively deeply to log in through the groove 25. The opposite pocket 1 is adjacent to the socket 7 to the head of the connecting element through hole 26 and approximately rectangular profile hole 27 in which the second Rethimno can be placed composite retainer element 90, covering the top of the locking lug 14 on the respective cylinder 13 of the connecting element. The locking element 90 includes a plug 91 and 92 of the locking part connected to each other with threaded connection 93 and the locking part 92 provided with a locking nose 94, which also scroogle on the front side 95 and covers the top of the locking lug 14. The locking element 90 is the object of a parallel application for the grant of a title of protection, so that further explanation is not provided here.

Constructive geometric implementation of the coupling element 10 is illustrated in more detail with reference to Fig.3-5. The connecting element 10 is made mirror-symmetrical relative to the vertical passing through the longitudinal mid-plane L and dividing the rod 12 is bisected by the Central plane M, and both heads 13 of the connecting element provided on facing away from the rod 12 and the end 16 of the head two wedge-shaped tapering locking tabs 14, as previously explained. The rod 12 has almost along its entire axial length, essentially, a permanent oval cross-section with depth T of the connecting element is greater than the thickness D of the connecting element. The maximum depth T in the longitudinal mid-plane L is constant in the field of stem 12 and head 13. The connecting element 10 in which blast rod 12 and in the area of both of the heads 13 of the Cup-shaped scroogle on the top 17 and bottom 18 and sides with a uniform radius of curvature, respectively, R Oand RUboth the radius of curvature mostly the same size and in the preferred underground use have a curvature radius R=100 mm around the centers of curvature in the longitudinal mid-plane L. the Rod 12 has, however, as shown in figure 3, in the middle of the recess 17 as a narrowing of the thickness D of the rod, forming the rod 12 place specified destruction.

Facing each other shouldered 11 on the opposite heads 13 are held between the flat and oriented parallel to the longitudinal mid-plane L side surfaces 18 of the heads of the connecting element and the transition to the terminal 12, respectively, convex-rounded or curved in the form of an arc of a circle with radius RSof curvature. Convex shouldered 11 can therefore our teams without pressure on the respective thrust surfaces (21, 1) pockets 1,2 bending globcover sections relative to each other. The ends 16 of the head 13 is rounded at the sections 16A above the locking tabs 14 with radius RKcurvature and areas 16B side of the locking tongues 14 with radius RTof curvature. In the depicted embodiment, the radii RS, RK, RO, RUof curvature are equal in size and are located within a distance In between the two flat side surfaces 18 and the depth T of the rod. The radius RTdistorting the EIT approximately 20% less than RK. Distance, i.e. the width of the connecting element 10 in the area of the heads 13, approximately twice the thickness D of the rod 12.

The top side 13' of the heads of the connecting element passing between the two side surfaces 18 curved with a radius ROcurvature around the centers of curvature in the longitudinal mid-plane L have on the transition to curved passing the end 16 of the connecting element of the transition section 19, which is also curved between the two side surfaces 18 and forms a sloping transition between the curved upper sides 13' heads of the connecting element and approximately vertically oriented end 16 of the connecting element. Forth from the figures it is seen that preferably made in the form of forgings connecting element 10 at the transition between the four shoulder 11 and the rod 12, the shoulder 11 and the top 13' and the lower 13" sides of the connecting element, the ends 16 of the heads of the coupling element and the locking tabs 14 and the like, has rounded transitions.

From figure 2 also shows that both pockets 1, 2 are inclined to the junction between the two pockets 1, 2 bottom 28, 29, and depth of both receiving sockets 3, 4 increases from the rear side to the front side 5, 6, so that the connecting elements 10 are in direct contact with the bottom 28 and 29 to Romanov only their heads 13.

The preceding description is for specialist, some deviations, which should be dealt with under the protection of the attached claims. An implementation option with the same radii of curvature of the ends of the heads, shoulders, upper and lower sides of the crank, and about 20% smaller radius of curvature of the side portions forms a preferred variant implementation. But the corresponding radii of curvature may be different from each other.

SUBSTANCE: method for extraction and underground use of coal includes cleaning extraction and dumping of coal, fixing and controlling ceiling and transporting coal along face to drift. On the drift, in moveable generator, coal is pulverized for intensive burning with use of jets in water boiler firebox, where high temperature of steam is achieved (about 1400 C), enough for decomposition of water on oxygen and hydrogen. These are separated, then oxygen is fed back to jets, and hydrogen is outputted along pipes and hoses in drifts and shaft. Variants of underground generator for realization of this method are provided. Also provided is method for extraction of disturbed coal beds by short faces. It includes extraction and dumping of coal on face conveyor, fixing of ceiling behind combine, moving conveyor line and support sections in direction of cleaning face displacement, control of ceiling with destruction and partial filling. Extraction of coal is performed in short curvilinear faces by long stripes along bed, in straight drive without forwarding drifts, with preservation and reuse of ventilation and conveyor drifts, equipped with mounting manipulator robots, with fixing behind combine by automatically operating support deflectors without unloading and displacing sections in area of coal extraction. Extraction and transporting of coal is performed by fast one-drum combine and curvilinear reloading conveyor, supplying coal to drift conveyor or immediately to underground gas or energy generator placed immediately on drift. Also proposed is face scraper conveyor for realization of said method, wherein pans are made with step along front face profile, greater, than along back one, while forming common line curved towards face with constant curvature. Also proposed is a method for controlling complex for unmanned coal extraction.
