Description

one

This invention relates to mining equipment.

Transport dump bridges are known for transporting and laying overburden into dumps, having trusses with supports on chassis carriages, belt conveyors and discharge devices in the form of chutes at certain points of the bridge. Due to the fixed location of the chutes, the overburden discharge device is filled in the form of cones, the angle of repose of which is significantly greater than the stable angle of repose of the dumps. This does not allow sufficient use of the capacity of the dumps, causing the threat of landslide effects. Increasing the number of leaks on the unloading device complicates the design of the bridge.

The aim of the invention is to provide the possibility of unloading the conveyor at any point along the span of the bridge.

For this purpose, the mobile loader mounted on the bridge is made in the form of a tray-shaped frame, provided with a roller roller support and human shields installed at an angle to the frame.

FIG. 1 shows the proposed bridge, a general view, in FIG. 2 - mobile unloading trolley; in fig. 3 is a section along A-A in FIG. 2; in fig. 4 is a section along BB in FIG. 2

The bridge consists of two onor 1s with undercarriages 2, trusses 3, a conveyor belt 4 with rollers 5 and a belt 6. A movable unloading carriage 7 is mounted on the bridge. The carriage 8 is moved by a system of ropes 8 with deflecting blocks 9 and driven from a winch 10. The unloading trolley is made in the form of a yoke-like frame 11, non-rolling around the roller supports 5. On the frame 11, transition roller rollers 12 and 13 are installed. Roller conductors 12 are designed to flatten the tape, and roller rollers to give it the shape of a reverse tray. In order to prevent the soil from getting on, the bearing supports 5 and the trusses 3 on the frame have guide plates 14 at an angle to the frame, providing unloading of the weights.

The overburden enters the conveyor belt 6 and is transported to the unloading carriage 7. On the unloading body / cke, the belt is curved and takes the shape of a reverse tray, while the rock rolls off

tape along the guide plates on both sides of the bridge to the dumps. The rock dumping is made from the bottom edge of the dumps in a uniform layer by moving the unloading carriage towards the top of the dumps.
