Description

Technical Field

[0001] The invention relates to the technical field of hydraulic support installation and transportation equipment in underground coal mines, and in particular to a hydraulic support transportation trolley. Background Art

[0002] The height of the hydraulic support in coal mines has increased rapidly with the improvement of mechanization level, while the width has not changed and is still 1.75 meters, which is mainly due to the limitation of the scraper conveyor. In this way, the hydraulic support has a high center of gravity, and it often flips during installation, and safety cannot be guaranteed. In addition, when unloading the hydraulic support, the existing hydraulic support transport vehicle will push the hydraulic support from the flat car to the wedge-shaped landing fork, such as Figure 5-Figure 7 As shown, the wedge-shaped landing fork is then pulled out to complete the ground unloading of the hydraulic support. It can only be unloaded but not reloaded, and the working process is irreversible. Summary of the invention

[0003] In view of the defects of the prior art, the present invention provides a hydraulic support transport trolley, which lowers the center of gravity during transportation and unloading, and particularly greatly improves the safety of the installation and transportation process of the hydraulic support on a large slope.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the present invention is a hydraulic support transport trolley, which includes a transport flat car, a horizontal-vertical conversion platform, a horizontal-vertical conversion platform jack, a rotating table, a fixing fixture and a fixing fixture jack; a rotating shaft slide is arranged at one end of the transport flat car, and a rotating shaft that can be translated is arranged inside the rotating shaft slide. One end of the horizontal-vertical conversion platform is connected to the transport flat car through a rotating shaft, and the other end of the horizontal-vertical conversion platform is connected to one end of the horizontal-vertical conversion platform jack by a pin shaft, and the other end of the horizontal-vertical conversion platform jack is fixed to the other end of the transport flat car by a pin shaft, a rotating table is installed on the horizontal-vertical conversion platform, a fixing fixture is arranged on the rotating table, and a fixing fixture jack is arranged on the fixing fixture.

[0005] Furthermore, running wheels are arranged at the bottom of the transport flat car, a transport track is arranged below the running wheels, and a vehicle stopper is arranged on the transport track.

[0006] Furthermore, the horizontal-vertical conversion platform is connected to the rotating platform via a slewing support bearing, and the rotating platform rotates on the horizontal-vertical conversion platform.

[0007] Based on the above technical solution, the rotating table and the horizontal-vertical conversion platform jack are fixed on the slewing support bearing, the horizontal-vertical conversion platform and the transport flat car are strung together with a pin shaft and can rotate relative to each other, the rotating table rotates on the horizontal-vertical conversion platform, the horizontal-vertical conversion platform jack controls the platform to convert vertically to horizontal, and the horizontal-vertical conversion platform jack is fixed on the transport car with a pin shaft. Under the action of the horizontal-vertical conversion platform jack, the platform can be adjusted vertically or horizontally, and can also move to the left or return to the right when horizontal. The hydraulic support is fixed on the rotating table by a fixing fixture, and the hydraulic support, the rotating table and the platform can be pulled horizontally under the action of the oil cylinder.

[0008] The beneficial effects of the present invention are as follows: the principle is different from that of existing loading and unloading transport vehicles. The present invention utilizes a loading and unloading method in which the hydraulic support is vertically flipped 90 degrees and can be rotated horizontally, thereby lowering the transportation center of gravity. After unloading, it can be reloaded, the loading is reversible, and the installation, adjustment and recovery of the underground hydraulic support can be realized. BRIEF DESCRIPTION OF THE DRAWINGS
