Description

one

The invention relates to the field of downhole j conveyor transport.

Drivers for scraper conveyors are known that contain a block of sprockets mounted on the frame and including two sides connected by a cross member and a bottom with upper and lower guides fixed on them, between which canopies and chains are placed. The frame allows the drive to be assembled with raising the working branch of the chain or horizontal running of the working branch of the chain to the drive sprocket unit. Such an embodiment of the drive frame ensures the operation of the conveyor with a excavation machine without preparing niches for different values of drift and creates the possibility of a complete unification of the main and end drives.

However, the frame of this design requires complete rewiring of the drive assembly units (a reducer with a clutch and an engine of the sprocket unit and rotation of the frame by 180, the absence of a bottom frame on the frame reduces the strength of the drive frame, and the docking of the frame with the pan-j

BOM is a rather complicated process

The purpose of the invention is to simplify the installation and disassembly of the gfivod and increase the rigidity of the frame.

This is achieved by the fact that the traverse is made in the form of an isosceles triangular prism and is provided with a removable plate in the form of a pentagonal prism, the traverse, the upper and lower rails, are located symmetrically relative to the horizontal plane passing through the axis of the sprocket and form together with the removable plate surface for the working branch of the conveyor.

FIG. 1 shows a drive frame with horizontal running of the working branch of the chain to the drive sprocket unit, cross section; in fig. 2 shows a section along A-A in FIG. one; in fig. 3 - drive frame with the rise of the working branch of the chain to the drive sprocket unit, with a transverse section; in fig. 4 is a section along BB in FIG. 2.:

FIG. The 1 and 2 arrows indicate the direction of movement of the working branch of the chain.

The frame includes a drive sprocket unit 1 (only the drum circumference of the drive sprocket unit is shown for simplicity), two BOSINS 2 and 3, bottom 4. The middle part of the frame is made of traverse 5 in the form of an equilateral triangular prism symmetric from the vertical axis 6, the star sprocket 1 and two guides 7 and 8, top and vdzhni, symmetrically located about axis 6, Between the crosspiece 5 and the guides 7 and 8 there is a window 9, covered by a removable rotary plate 10 in the form of a pentagonal prism ;. Working surfaces 11 and 12 traverse 5. Made inclined. Swivel plate 10,. guides 7 and 8 have inclined working surfaces 13-15 and horizontal working surfaces 16-18. Moreover, the nodes of the inclined working surfaces llr-lS, traverse 5, on the gate plate 10 and the guides 7 and 8 are equal. The crosspiece 5 is attached with a visor 19 with a horizontal working surface 20, a goat of rivers 21 with an inclined working surface 22, and a chain 23 with a horizontal 24 and inclined 25 working surfaces, with the mounting. 26 and 27 of the chain pullers to the crosspiece 5 are arranged symmetrically about the axis 6. To skip the transported material when assembling the frame of FIG. 2, a window 28 is made in the guide 7 (see FIG. 4), which, when the frame of FIG. 1 is overlapped with sheet 29 (see Fig. I2). The mounting of the drive frame with horizontal running of the working branch of the chain to the drive sprocket unit is carried out as follows. The visor 19, chain pullers 23, turning the plate 10 with its horizontal working surfaces 20, 24, 16 are mounted and fastened by known methods on the traverse 5 above the horizontal axis 6, and the visor 21 is located below the axis 6. Then a sheet is mounted on the guide 7 29 (see FIG. 2). The mounting of the drive frame with the raising of the working branch of the chain is carried out by turning 180 relative to the axis 6 of the visors 19 and 21, the pullers 23, the rotary plate 10; in such a way that their inclined working surfaces 25, 22, 13, the surface 12 of the trap 5, the surface 15 of the guide 8 are guides for the working branch of the chain. Sheet 29 is dismantled.: Subject of the Invention The drive of the scraper conveyor, comprising a block of sprockets mounted on a frame and comprising two side walls connected by a cross member and bottom with upper and lower guides fixed on the imx, canopies and chain pullers, characterized in that simplify installation and disassembly of the drive and; increase the rigidity of the frame, traverse done-. It is not in the form of an isosceles triangular prism and is provided with a removable plate in the form of a pectangular prism, the traverse, the upper and lower guides are located symmetrically relative to the horizontal plane passing through the axis of the sprocket unit and form together with the removable plate one surface for the working branch of the conveyor. 20 25- 2721 19
