The invention relates to mining, namely conveyors used in underground mining, immediately adjacent to the bottom openings, in particular when you restart the rock mass with the scraper loader conveyor belt.Known rotary mobile crane construction Glienicke, the main structural features which are samoparodijnye design, pivotally mounted on the main frame of the truck, self-levelling design and the possibility of horizontal shifting (brochure factory Glinik. Transport and shipping control device. Gathering conveyor. Slewing mobile crane. Producent: Fabryka Maszyn Glinik S. A. 38-320 Gorlice ul. Michalusa 1. Brochure of the 3rd International exhibition-fair "Russian Coal" from 23 to 26 April, Novokuznetsk, advertising which W. "Coal" N 8-11 for 1996).An obvious shortcoming of the known material handler is the absence of a lateral, cross-regulation of the location of the loader in the development.The hydraulic cylinder moving the material handler is directly connected to the structure of the front frame in a weak soil movement due to overturning moment, associated with irrational place effort of movement.Pivotally mounted on the main frame truck when uneven development rasklinivanie on the guides, which is associated with the loss of continuity and additional costs to eliminate jamming.Execution of detachable clamps lifting cylinders not only complicates the design and increases the cost, but reduces the strength of the clamps, which are significant bending efforts at movement.Deflecting roller tape built inside the sides of the truck that requires a special slit-Windows in the sides, weakening the metal and complicating the placement and installation of the deflecting roller.Closest to the proposed to the technical essence and the achieved result is a movable reloading paragraph, including the main frame, on which is placed the end drum of the conveyor belt and face the tailpiece with dropping head installed with the possibility of longitudinal movement, the centering device belt deflecting rollers mounted between end drum belt conveyor and discharging golovchanskaya, moving and fixing elements (patent RF N 2044890, CL E 21 F 13/08, 1995) is adopted for the prototype.Work known mobile transshipment point lack of effective due to tight binding of movement transshipment point for movement of powered roof supports. Often the willingness lining to the movement does not coincide with the willingness of movement of the transshipment point, which leads to deter or full suspension of work on the movement as a lining, and conveyors, forming a transshipment point.In addition, the presence of the known transshipment point Platonova the grounds on which the metal material handler with the head end face of the conveyor belt, as well as farm loader, located on the ground generate, create considerable resistance to the movable structure. Especially this resistance manifests itself in the soil produce low bearing capacity or uneven, bulging from high rock pressure of the soil. In these cases, the shifting associated with considerable difficulties in clearing the soil production, cleaning, hanging out separate parts of conveyors using auxiliary prisposoblenka position of the end drum of the conveyor belt, where is ensured only regulation in the horizontal plane and does not provide for vertical adjustment.The invention consists in the fact that mobile reloading item includes the main frame, on which is placed the end drum of the conveyor belt and face the tailpiece with dropping head installed with the possibility of longitudinal movement, the centering device belt deflecting rollers mounted between end drum belt conveyor and discharging the cylinder, loader, located vertically support and horizontally mounted cylinders of transportation, guides, mobile and fixing elements, wherein the movement mechanism is made in the form of a plunger, one side of the cylinder which is connected with the rear support of the main frame, provided with cylinders with rings bearing is moveable, and the holder of the lift cylinder movable supports are made integral with each lift cylinder to a bottom provided with a ball support, built-in skid cylindrical cross-sectional shape that is associated with the rail.In addition, the frame of a gate drive perigee made with the possibility of rotation and fixation in the crawler body trunnion with a rectangular cutout, which is rigidly fixed to the shaft deflecting roller.In addition, on the frame of the follower rigidly mounted bearing which is provided with a dog that is installed on the axis of the support.Significant factors influencing technical result achieved are in causal relationship with the specified result.So, the link rod of the hydraulic cylinder of the plunger from the rear support of the main frame, instead of with the main frame in the prototype, reduces excessive stresses in the metal, reduces the risk of overturning moment, improves handling transshipment point for the movement, reduces the likelihood of immersion in the soil and standing to his feet.Run clips of cylinders one-piece, integral, increases the structural strength, making it less time-consuming to manufacture and operate, reduces the intensity and, finally, the cost of manufacturing the TRANS-shipment point in General.Due to the fact that each lift cylinder to a bottom provided with a ball support, built-in skid cylindrical cross-sectional shape that is associated with directing, increased longitudinal and lateral stability peregrine, the presence of ball bearings allows the support element - anchor ski, copy the soil profile and does not allow installation of the ski at an angle to it, which could have a negative impact on their interaction. Snake inside the guide has a cylindrical cross-sectional shape that prevents them from jamming and reduces the contact load on the surface of interaction.Installed in the body of the truck with the possibility of rotation and fixation pin with a rectangular cutout, which is rigidly fixed to the shaft deflecting roller, allows you to refuse the execution of a special slit-Windows in the sides of the truck with the placement of these Windows deflecting roller. The Windows in the sides of the truck weaken the metal structure complicate the installation and placement of the deflecting roller. In the proposed design of the shaft deflecting roller together with him is inserted into the rectangular cut-out axle and is fixed therein, and the axle rotate and fixed in the desired position on top of the body of the truck, providing the necessary deflection of the conveyor belt.In the proposed technical solution, the axis of pawl mounted on one leg instead of two designs in the prototype that call is NCTA.Thus, the technical result of the proposed solutions is to increase stability and control, simplifying the structure, reducing the metal in the manufacture and the complexity of operation, which ultimately improves the reliability, performance and efficiency of mobile transshipment point.In Fig. 1 shows a mobile reloading point, side view; Fig. 2 - the same as in Fig. 1 is a top view of Fig. 3 is a view As in Fig. 1; Fig. 4 - view of B in Fig. 3; Fig. 5 - the same as in Fig. 3 is a top view of Fig. 6 - a view b-b In Fig. 3; Fig. 7 is a view G-G of Fig. 5; Fig. 8 - node D in Fig. 1; Fig. 9 is a view of e-E in Fig. 8; Fig. 10 - type f-F in Fig. 2.Gathering transshipment point consists of gathering material handler 1, the drive frame 2 which from discharging head 3 is fixed by means of vertical pins 4 on the movable platform 5 mounted on the carriage 6.
