Problems solved by technology

At this time, the hydraulic support truck has become the main equipment for transporting hydraulic supports. Most of the existing hydraulic support trucks are divided into shovel-type bracket trucks, flat-bed trailer-type bracket trucks, and "U"-shaped frame-type bracket trucks. Among them, the "U" frame type support truck has the advantages of light weight, low center of gravity, stable operation, convenient loading and unloading, fast transfer speed, and better driver's sightlines during operation, and is widely used. However, the existing "U" frame The hydraulic support truck has poor adaptability and can no longer meet the requirements of various road conditions in the coal mine. During the transportation process, the rigid collision between the hydraulic support and the hydraulic support truck body will inevitably occur. When working conditions such as slope, starting, braking, parking, bumping, etc., the hydraulic support will shake a lot in the car body, which will have a greater impact on the car body. When the shaking is serious, the hydraulic support will directly collide with the car body, causing the car body to Both the car body and the hydraulic support will be greatly damaged. Once the car body is seriously damaged, the hydraulic support may suddenly fall, which will threaten the safety of the hydraulic support truck and the operator. Since the width of the U-shaped frame of the U-shaped support truck cannot be adjusted, when transporting some hydraulic supports with different sizes and models, because the width of the U-shaped frame cannot be adjusted, at this time, to a certain extent, only some U-shaped frames with a width smaller than the U-shaped frame can be transported. The width of the hydraulic support is therefore limited so that its applicability is greatly reduced, and the lifting device on the U-shaped frame of the existing "U" frame type support truck is set to be fixed and cannot move forward and backward. When transporting different types of hydraulic supports The positions of the hoisting ports are also different. At this time, the lifting device cannot be moved to the position of the hoisting port of the hydraulic support due to the non-adjustable position, which is not conducive to the hoisting work. It is particularly important to have a mechanical transmission frame type hydraulic support transfer machine with better positioning and the lifting device can be adjusted according to needs.

Abstract

The invention relates to a mechanical transmission frame type hydraulic support transportation machine. The mechanical transmission frame type hydraulic support transportation machine effectively solves the problem that an existing hydraulic support transportation machine cannot be suitable for carrying hydraulic supports with different models and sizes. According to the technical scheme, the mechanical transmission frame type hydraulic support transportation machine comprises a towing vehicle, wherein the towing vehicle is connected with a U-shaped frame composed of two L-shaped vehicle bodies; lifting devices are arranged at the upper ends of the vehicle bodies, and adjusting devices for adjusting the distance between the two L-shaped vehicle bodies are arranged at the portions, parallelto a fixing plate, of the two L-shaped vehicle bodies; and jacking devices which are driven by first driving motors and can jack up the L-shaped vehicle bodies are arranged in the two L-shaped vehicle bodies, and the jacking devices can be driven to jack up the two L-shaped vehicle bodies before the distance between the L-shaped vehicle bodies is adjusted, so that the L-shaped vehicle bodies arejacked off the ground, and then the distance between the two L-shaped vehicle bodies can be adjusted through the adjusting devices.

Description

technical field [0001] The invention relates to fully mechanized mining equipment in coal mines, in particular to a mechanical transmission frame type hydraulic support transporter. Background technique [0002] Hydraulic support is an important part of comprehensive mechanized mining equipment in coal mines. The hydraulic support can reliably and effectively support and control the roof of the working face, maximizing the safety of coal miners. Due to the large load and irregular external structure, when the hydraulic support is transferred over a long distance, a special hydraulic support truck is usually used to transport the hydraulic support. At this time, the hydraulic support truck has become the main equipment for transporting hydraulic supports. Most of the existing hydraulic support trucks are divided into shovel-type bracket trucks, flat-bed trailer-type bracket trucks, and "U"-shaped frame-type bracket trucks. Among them, the "U" frame type support truck has the...
