The invention concerns a connecting device for plow units with a control system to control the horizon cutting plane, in particular a coal plough, with a compound of the connecting bracket, welded to Galabovo section or the guide section of the plow, the main part of which is made in one piece with the plot hinged socket for pivotally receiving rod ends of the hydraulic cylinder control the transverse slope of the conveyor plow, and also have made are offset in height relative to the swivel jacks fork console focus, which includes two spaced parallel, vertically passing shelves, the inner side being located opposite each other at a distance and provided with holes the bolt for receiving a hinge bolt, interacting with the main part of the cantilever beams.

In underground mining plants mining machine is directed to the face conveyor formed from the transport section or respectively golobovih sections, which for this purpose includes, in this case, appropriately designed a guiding device of a plane. Depending on the execution of a plane in the form of a sliding plane or tear Struga guiding device Struga is located outside the s stope or goaf design of the lateral cheeks of Galabovo or the transport section. The shifting of the plow is on the reverse or cantilever beams, which rest on the frame support, and the head of cantilever beams through the hinge bolt is mounted on a cantilever attaching connective console. To be able to tilt the plow installation perpendicular to the layer plane and be able to adjust its angular position in a horizontal layer, use control console with hydraulic cylinders control the transverse slope of the conveyor plow that one party to rely on the cantilever beam, and the other party in the hinge slot on the console connection.

The appropriate type of connecting device connecting the console to tear the plane is known from the document DE 4233840 A1. Connecting the console consists of a welded structure with a large number of individual elements, and the hinge socket receiving the head portion of the cylinder control the transverse slope of the conveyor plow is composed of two strand each other parts.

The appropriate type of connecting device for a sliding plane is known from the document DE 3300306 A1. There's also the hinge socket formed of two parts, one part forms the main part (body), to the th through fixture Rethimno strengthens the trailing element. The main part connecting the console is screwed from the side of the goaf to the side plates golobovih sections. Shelves for the reception of hinge bolts consist of a separate fork connecting the console with two passing down the legs, which are formed bolt holes for the hinge bolts.

The objective of the invention is to simplify the design of the connecting device and the transmission of a higher force while at the same time high reliability, due to the design.

This problem is solved according to the invention by the fact that the main part (body) connecting the console is made in the form of the casting, both regiments formed in one piece with molded detail, on their outer sides provided with a molded in one piece and protruding on the sides of the shelf support ribs, and/or holes bolt conically diverging from the inner to the outer side for insertion of interacting with the hinge bolt of the clamping parts. In General, due to the implementation of the connective console in the form of the casting design connecting the console easier. Panelists and speakers in one piece with the main part of the shelves supporting ribs contribute to lateral stability and podpisaniu connecting console welded is Galabovo section or respectively to the guide section. At the same time this design allows the use of connecting console and yet only a connecting device as in installations of moving planes and installations tear planes and, therefore, should no longer be used for different plow installations of different coupling devices. With clamp parts of the hinge bolt can reliable operation be inserted and clamped in a conically widening towards the outside of the bolt holes, resulting prevents that due to the backlash of the hinge bolt in the bolt holes can be increased wear of the bolt holes.

According to a preferred variant implementation made in one piece with shelves supporting ribs are at least partially to the level of the bolt holes in the shelves. The support ribs may continuously or progressively expand from their free ends to the base area on the outer edges of the shelves to reach the optimal rigid in operation the connection between the supporting ribs and shelves. Further preferably, if the main component of the connective console has a protruding from the base of the ribs to the upper side, closed at least relative to the goaf side of the rear wall, so that by connecting to the Soli prevent the infiltration of fine coal or the like in Galabovo the conveyor section.

Clamping parts may consist mainly of sleeves with a tapered external shape and/or tapered holes. Particularly preferably, when clamping the parts consist of sleeves having a longitudinal slot to facilitate and improve the clamping of the hinge bolt in the bolt holes. The sleeve may have, in particular, protruding inside the jumper ring at its wider base. This exercise has, in particular, the benefits, if both ends of the hinge bolts have a threaded neck, which then for mounting and fixing screwed or screwed a nut. Threaded neck can be mounted, in particular through the ledge relative to the end sections of the hinge bolt, so that the ring straps on the sleeves, can be provided in contact with the ledges. Further preferably, the hinge bolt has a middle portion with a barrel-shaped contour, so that the thickness or cross-section of the hinge bolt increases from the end sections to the middle of the hinge bolt. Barrel contour of the middle section improves the function of the bearing cantilever beam hinge bolt. Further, the hinge bolt can preferably have two final section, which conically taper proceeding from the middle of the site, and to interact with the practical hole in the sleeve.

Further, particularly preferably, if the inner side shelves pass, respectively, through the bevel or chamfer to the edge of the shelf. Using bevels can interfere with the fact that the operation mode can be pressed briquettes from coal fines in the gap between the outer surfaces of the head part of the cantilever beams and the inner sides of the shelves, resulting in greatly increased service life of the connecting console. Bevels facilitate the squeezing of solids such as stones or bricks, in particular, when the horizontal rotary movement between the head part of the cantilever beams and Galabovo section or, respectively, the transport section.
