Double-track four-crane conveyor

Abstract

The invention discloses a two-track four-lift conveyor. The upper edge of the track is connected with the track fixing mechanism, and the lower edge is slidingly connected with a wheel set mechanism and a traction mechanism. The wheel set mechanism is connected with the cross mechanism, the cross mechanism is connected with the lifting cylinder, and the piston rod in the lifting cylinder is connected with the hook. The pulley is connected, the hook connecting plate is connected with the hook, the track fixing mechanism is connected with the anchor device, and the anchor device is fixedly connected with the coal seam roof. The structure is simple, the use is convenient, the installation and disassembly of the hydraulic support is fast, the lifting stability is reliable, the relocation cost is low, and the time is short. In the past, it took about 30 days to relocate a working face, but it only takes 5-8 days to complete the relocation by using the present invention. The efficiency is more than 5 times, and it can be widely used in coal mine fully mechanized mining face.

Description

technical field [0001] The present invention relates to a kind of hoisting mechanical equipment, in particular to a kind of double-rail four-lift handling machine. Background technique [0002] There are many types of hoisting machinery on the market, and more than 99% of them are used to lift materials on the ground. It is not limited by any space and terrain. However, it is obvious that the above-mentioned equipment is used in mines. Powerless, because the space and terrain under the mine are limited, especially the hydraulic support used in the coal mining face, each support weighs about 20 tons, and there are more than 100 hydraulic supports in a coal mining face, currently installed or dismantled Most of the hydraulic supports are first dragged to the floor by a winch, and then pulled on a flatbed truck to be transported to a new working surface for reinstallation. There are the following disadvantages in relocating hydraulic supports in this way: [0003] (1) The unde...

AI Technical Summary

Problems solved by technology

[0003] (1) The underground floor is soft or has a bottom drum phenomenon, and the weight of the bracket is heavy, so it is difficult to drag the bracket;

[0004] (2) When the bracket is dragged or towed to the flatbed truck, its moving direction is not easy to control, and the bracket needs to be adjusted separately on the flatbed truck;

[0005] (3) When the bracket is on the flatbed truck, a steel slope is required as the drag bridge deck. Since the bracket moves along the steel slope during dragging, its frictional resistance is large, sparks are easily generated, and gas explosions are prone to occur, resulting in safety of personnel and mines;

[0006] (4) The relocation speed is slow. If the floor of the working surface is soft, it usually takes about 30 days to relocate a working surface, and it is also difficult to install again. The work efficiency is low, which increases the cost of relocation. At the same time, it produces less coal and the overall efficiency decreases;

[0007] (5) Due to the slow speed of relocation, it is easy to cause the goaf to be unable to be topped in time, which affects the safety of workers and equipment, and the loss is immeasurable

[0008] (6) It is difficult to control the position when the bracket is dragged or the bracket is not installed in place. It takes a lot of time to adjust the position, wasting manpower and material resources
