Description

Technical Field

[0001] The invention relates to the technical field of mine tunnel construction, and in particular to an ultra-low underground mining loader. Background Art

[0002] Underground operations usually use underground mining loaders for shoveling, short-distance transportation and material loading. Underground loaders can mine and dig coal, ore and other materials in the mine. They are efficient, accurate and safe. They can transport the materials mined from the mine to the ground through a winch system, or directly transport them to the corresponding processing equipment through underground transport vehicles. They can transfer the mined materials to transport vehicles, intermittent conveyors or roller conveyors and other loading equipment to achieve rapid and efficient transfer of materials. The following problems exist in the existing technology:

[0003] Because heavy metal mines usually require a narrow working surface with a height of less than 2 meters and a width of less than 1.8 meters, while the existing 2-ton underground mine loader has a vehicle height of 2.3 meters and a vehicle width of 1.9 meters, which is difficult to meet the operating requirements. At the same time, in order to improve the safety of underground operations, mining companies have gradually increased their requirements for unmanned and less-manned operations, but existing underground loaders are mainly manually operated, and remote control technology is rarely used on small mine loaders. In addition, due to the high specific gravity of metal ore, overloads often occur during operation, leading to failures or even damage, which seriously affects the life of the entire machine. Existing underground loaders do not provide overload protection for the entire machine, and the equipment, especially the working device, is easily damaged. In addition, mine operating conditions usually have insufficient lighting and poor visibility, and the loader is prone to bumps and damage. At the same time, due to the structural limitations of the underground transport vehicle, the underground loading and unloading height requirements are greater than 1.7 meters, and the unloading angle is above 40°. Therefore, the maximum working surface of the underground loader (the highest point of the bucket from the ground) will exceed 3 meters, while the underground tunnel is usually less than 2.6 meters high. Therefore, loading in the tunnel is difficult and the flexibility of underground operations is poor. Summary of the invention

[0004] The present invention provides an ultra-low underground mining loader to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] An ultra-low underground mining loader comprises a cab system, wherein a front frame system is arranged on the front side of the cab system, a double-variator system is arranged on the rear side of the cab system, a rear frame system is arranged on the rear side of the double-variator system, drive axle systems are arranged on the left and right sides of the front frame system and the rear frame system, the cab system comprises two cab frame bottom plates, a connecting reinforcing rib is fixedly installed on the rear side between the opposite surfaces of the two cab frame bottom plates, seat mounting plates are fixedly installed on the opposite surfaces of the two cab frame bottom plates, a riding mechanism is arranged on the top of the two seat mounting plates, and a connecting front plate is fixedly installed on the frontmost side between the opposite surfaces of the two cab frame bottom plates.

[0007] A further improvement of the technical solution of the present invention is that the riding mechanism includes two stepped bottom plates, rubber shock absorbers are fixedly installed at the bottom of the front horizontal parts of the two stepped bottom plates, and seats are fixedly installed at the top of the rear horizontal parts of the two stepped bottom plates.

[0008] A further improvement of the technical solution of the present invention is that two fixed adjustment columns are fixedly installed on the top of the two cab frame bottom plates, telescopic adjustment columns are slidably installed on the inner sides of the two fixed adjustment columns, and the fixed adjustment columns and the telescopic adjustment columns are each provided with a number of positioning holes that pass through the left and right, and the several positioning holes are all formed by bolts passing through the positioning holes formed by the fixed adjustment columns and the telescopic adjustment columns, and a ceiling is provided on the top of the four telescopic adjustment columns.

[0009] A further improvement of the technical solution of the present invention is that: the front frame system includes a radar camera module one, radar camera modules three are fixedly installed on the left and right sides of the cab frame bottom plate, an electrically controlled switching mechanism is arranged on the left side of the riding mechanism, a radar camera module two is fixedly installed on the bottom front side of the ceiling, and the rear frame system includes a radar camera module four.

[0010] A further improvement of the technical solution of the present invention is that a sensing telescopic cylinder is fixedly installed at the front end of the front frame system, a loading bucket mechanism is provided at the front end of the sensing telescopic cylinder, a display alarm system is fixedly installed at the top of the connecting front plate, and an overload control system is provided behind the radar camera module three.

[0011] A further improvement of the technical solution of the present invention is that the loading bucket mechanism includes bucket one, bucket two is movably installed above the left and right sides of the inner wall of bucket one, a telescopic cylinder is fixedly installed in the middle of the rear side of bucket one, and the output end of the telescopic cylinder is movably connected to the rear end of bucket two.

[0012] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0013] 1. The present invention provides an ultra-low underground mining loader. Through the mutual cooperation among the front frame system, the double-variator system and the rear frame system, articulated front and rear frames are adopted, and the structure of the whole machine is more stable. At the same time, the double-variator system and the drive axle system are all moved backward to make room for the cab system. The cab system changes the previous structural form above the double-variator system, and uses the space left by the double-variator system and the drive axle system to sink and ensure the height of the whole machine. While ensuring the working space, the height of the whole machine is effectively reduced to ensure the passability.

[0014] 2. The present invention provides an ultra-low underground mining loader, which is equipped with electric control and manual control dual-mode switching, and configured with a remote control mode, as well as the mutual cooperation between the operation overload protection system, thereby reducing the frequency of personnel operation, using radar to improve driving safety, and preventing operation overload, thereby effectively improving the operation safety of the underground mining loader.

[0015] 3. The present invention provides an ultra-low underground mining loader, which can effectively reduce the unloading height of the underground mining loader and avoid excessive height through the cooperation between the sensing telescopic cylinder, the loading bucket mechanism, bucket one, bucket two, and the telescopic cylinder, so as to load vehicles in a narrow underground working environment and improve applicability.
