Abstract

The loading and transport module includes a fixed chute, a frame mounted in it with the ability to perform reciprocating movement, and transporting elements installed on the frame with the ability to perform translational movement in the form of parallel-installed scrapers. The drive of the transporting elements contains a chain transmission and a drive shaft. The drive shaft is equipped with overrunning clutches in the form of gears that mesh with racks mounted on a stationary chute, one of which is installed with the possibility of rotating the drive shaft in the direction of transporting the material during forward motion, and the second - during reverse motion. The transporting elements and the chain drive are connected to each other and are made in the form of parallel-installed scrapers attached to traction chains.

Technical efficiency consists in reducing the metal consumption of the structure and reducing the power supply of the loading and transport module while maintaining the specified productivity.

This useful device is based on the principle of continuity of the process of loading lump rock mass during the forward movement of transporting elements in the form of parallel installed scrapers and the cyclic return movement of the loading module frame.

Description

The utility model relates to mining, in particular to machines for loading and transporting lump material in the conditions of quarry benches, mine workings and mines.

There is a known design of a loading and transport module containing a chute in which interconnected transport elements are installed with the ability to perform reciprocating movements relative to the chute (Pat. 2137694 MPK B65G 65/02. Loading machine / G.Sh. Khazanovich, Yu.M. Lyashenko, A.V. Otrokov, E.V. Nikitin - Announced 04/21/98; Published 09/20/99, Bulletin No. 26).

The closest to the proposed one is a loading and transport module, which includes a stationary chute, a frame mounted in it with the ability to perform reciprocating movement, a transporting element in the form of a closed belt mounted on the frame with the ability to perform translational movement, and driving the latter in motion, rotating by means of a chain transmission. (Utility model patent 144 241 Russian Federation, IPC B65 G 65/02 (2006.01). Loading and transport module / Yu.M. Lyashenko, E.A. Revyakina, A.Yu. Lyashenko // No. 2014110347/11; declared 03/18/2014; published 08/10/2014, Bulletin No. 22.)

The main disadvantage of the prototype is the need to set in motion a large mass of actuating elements, including a closed belt and rollers, during loading and transport operations.

The purpose of the device is to reduce the metal consumption of the structure and reduce the power supply of the loading and transport module while maintaining the specified productivity.

According to the design, the task is achieved by the fact that the loading and transport module includes a stationary chute, a frame mounted in the chute with the ability to perform reciprocating movement, and transport elements installed on the frame with the ability to perform translational movement by means of a drive. The drive of the transporting elements contains a chain transmission and a drive shaft. The drive shaft is equipped with overrunning clutches in the form of gears that mesh with racks mounted on a stationary chute, one of which is installed with the possibility of rotating the drive shaft in the direction of transporting the material during forward motion, and the second - during reverse motion. The transporting elements and the chain drive are connected to each other and are made in the form of parallel-installed scrapers attached to traction chains.

The essence of the device is illustrated by drawings. In fig. 1 shows the loading and transport module, Fig. 2 - aka, top view.

The loading and transport module includes a fixed chute 1 and a frame 2 installed in it, which has the ability to perform reciprocating movement from hydraulic cylinders 3. The transporting elements are made in the form of parallel-installed scrapers 4 and are fixed on traction chains 5. The scrapers 4 are driven by traction chains 5 movement by the drive shaft 6, which is equipped with overrunning clutches 7 and 8 in the form of gear wheels that mesh with tray-mounted rails 9 and 10, one of which 9 is installed with the possibility of rotating the drive shaft in the direction of transporting the material during forward stroke, and the second 10 - on the contrary.

The device works as follows. After loosening the rocks, the loading and transport module with its front part is inserted into the stack of lumpy rock mass in the position shown in Fig. 1.

The loading cycle begins with the operation of hydraulic cylinders 3, under the influence of which the frame 2 moves relative to the chute 1. In this case, the gear wheel engaged with the rack 9, through the overrunning clutch 7, rotates the drive shaft 6 in the direction of transporting the rock mass. Rotation of the drive shaft 6 drives the traction chains 5 and the scrapers 4 attached to them, which carry the rock mass to the unloading part of the loading and transport module. The overrunning clutch 8 is in the disengaged state.

After reversing the hydraulic cylinders 3, the frame 2 moves in the direction of the stack of lumpy rock mass. At this time, the overrunning clutch 8, which engages with the rack 10 by means of a gear, rotates the drive shaft 6 and the traction chains 5 associated with the latter with fixed scrapers 4 in the direction of transporting the rock mass, which ensure further movement of the rock mass to the unloading part. The overrunning clutch 7 is in the disengaged state.

The forward movement of the traction chains 5 with fixed scrapers 4 in the direction of the unloading part during the cyclic return movement of the frame 2 ensures the continuity of the process of transporting the lump rock mass.

Thus, the proposed loading and transport module, equipped with scrapers attached to traction chains and installed in parallel, compares favorably with existing analogues in that this design reduces the metal consumption of the structure and reduces the power consumption of the loading and transport module, which generally helps to increase the efficiency of the work process when maintaining the specified performance.
