Problems solved by technology

[0003] The support truck is specially used to transport the underground support supports. Because most of the support supports are heavy, the lifting and unloading are cumbersome, repetitive and labor-intensive, and are likely to cause safety accidents.
[0004] At present, the hoisting mechanism of the support truck is relatively backward, with insufficient strength, and there are many disadvantages and potential safety hazards

Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing:

[0025] figure 1 As shown, it is the overall structure diagram of the lifting and unloading device. The connection relationship and position of each part must be correct and the installation should be firm.

[0026] The lifting cylinder is fixed on the base by the left and right cylinder ears and the left and right support plates, and the boom is connected between the left and right support plates on the upper part. The boom is fixed on the spline shaft of the sprocket, and the spline shaft of the sprocket is fixed with the sprocket Connecting, a circular chain is set on the sprocket to form a lifting and unloading device, and the four lifting and unloading devices form a lifting and unloading whole, and at the same time hook the support bracket, and complete the lifting and unloading action under the power of the lifting hydraulic cylinder.

Abstract

The present invention relates to a hoist device of bracket transport vehicle. The main structure is composed of a base, a hoisting oil cylinder, a hydraulic balance valve, oil cylinder ears, an oil cylinder shaft, a sprocket wheel, a sprocket wheel spline shaft, supporting plates, a lifting chain, a lifting hook and a screw bolt. The invention adopts a design that the hoisting oil cylinder, the round link chain and the sprocket wheel are integrated. The hoisting oil cylinder adopts a telescopic plug-in type balance valve and has the functions of self locking, buffering and smooth descending. The lifting chain adopts the round link chain and has strong interchageability. The sprocket wheel adopts the design of double sprocket tooth sockets and has large chucking force. The sprocket shaft adopts a double spline connection and is simple and reliable. The self-unloading device has a hoist body composed of a front body, a back body, a left body and a right body. The hoist device of the invention has the advantages of reasonable designing, compact structure, large force of the hydraulic oil cylinder, strong hoisting capacity, high efficiency, stable and reliable safety, and convenient operation. The hoist device of bracket transport vehicle is ideal for the down-hole bracket transport vehicle of mine and can also be installed on other vehicle types.

Description

technical field [0001] The invention relates to a lifting and unloading device for a support truck under a coal mine, and belongs to the technical field of design and manufacture of parts of auxiliary transportation equipment under a coal mine. Background technique [0002] Under the coal mine, a large number of supporting brackets are used. These brackets are often quickly dismantled, moved and installed according to the needs of the mining progress, and the transportation volume is large and the labor intensity is high. [0003] The support truck is specially used to transport the underground support supports. Since most of the support supports are heavy, the lifting and loading and unloading are cumbersome, repetitive and labor-intensive, and are likely to cause safety accidents. [0004] At present, the hoisting mechanism of the support truck is relatively backward, with insufficient strength, and there are many disadvantages and potential safety hazards. Contents of t...
