Description

Technical Field

[0001] The present invention relates to the technical field of coal mining operations, and specifically to a hydraulic support roadway transportation device for coal mining. Background Art

[0002] A hydraulic support is a structure used to control the mine pressure in a coal mining face. The mine pressure in the coal face acts on the hydraulic support in the form of an external load. In the mechanical system of the interaction between the hydraulic support and the surrounding rock of the coal face, if the resultant force of each support member of the hydraulic support and the resultant force of the external load acting on the hydraulic support from the roof are exactly on the same straight line, then the hydraulic support is very suitable for the surrounding rock of this coal face.

[0003] During the coal mining operation process, a hydraulic support is required, and a transportation device is needed to transport the hydraulic support to a designated position. However, during the use of existing transportation devices, most of them simply clamp and fix the two sides of the hydraulic support, and there is no support and fixation above the hydraulic support. As a result, during transportation, the hydraulic support is prone to tipping over, and most of the clamping and fixation of the hydraulic support is relatively complex to adjust, which is time-consuming and laborious. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that during the use of existing transportation devices, most of them simply clamp and fix the two sides of the hydraulic support, and there is no support and fixation above the hydraulic support, resulting in the hydraulic support being prone to tipping over during transportation, and most of the clamping and fixation of the hydraulic support is relatively complex to adjust, which is time-consuming and laborious, and to propose a hydraulic support roadway transportation device for coal mining.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

The end of the first connecting rod away from the first rotating shaft is rotatably installed at one end of the second connecting rod. The two sliding plates form a reverse movement adjustment structure through the first connecting rod and the second connecting rod.

[0010] As a preferred embodiment of the present invention, two first lead screws are provided. The two first lead screws form a rotational adjustment structure through the motor. The first lead screw is in threaded connection with the sliding frame, and the two sliding frames are respectively in threaded connection with the two first lead screws in opposite directions.

[0011] As a preferred embodiment of the present invention, the first bevel gear meshes with the second bevel gear. The first lead screw and the second lead screw form a synchronous rotational adjustment structure. The second lead screw is in threaded connection with the support rod.
