[0033] Working principle:

[0034] See Figure 1, the first platform base 1 to the sixth platform base 27 are assembled together in sequence. The platform bases are welded and processed with steel plates and are divided into 6 pieces as a whole, which is convenient for disassembly and installation. The oil cylinder guide pulley 19 slides along the pulley guide groove 20 under the action of the oil cylinder telescopic rod 131 of the pushing oil cylinder 13. One end of the traction chain 30 is connected to the chain connecting piece 16. The traction chain 30 is wound around the oil cylinder guide pulley 19 and the base guide pulley 17 in sequence as required (or the traction chain 30 is wound around the oil cylinder guide pulley 19), and the other end of the traction chain 30 is connected to a hydraulic support (a mining equipment, not shown in the figure). The oil cylinder guide pulley 19 and the traction chain 30, as auxiliary components, cooperate with the pushing oil cylinder 13 to complete the traction extraction and orientation adjustment of the hydraulic support.

[0035] The pushing oil cylinder 13 controls the movement of the oil cylinder telescopic rod 131 through a hydraulic control valve group (prior art, not shown in the figure).

[0036] See Figure 1 , through the hydraulic control valve group, the movement of the oil cylinder telescopic rod 131 of the pushing oil cylinder 13 (the pushing oil cylinder is used for the traction and orientation adjustment of the hydraulic support) is controlled. The movement of the oil cylinder telescopic rod 131 drives the oil cylinder guide pulley 19 to slide in the pulley guide groove 20, and the traction chain 30 wound around the oil cylinder guide pulley 19 moves. The traction chain 30 pulls the hydraulic support to enter from the upper end of the first platform base 1 to the upper end face of the first platform base 1. During the movement of the hydraulic support, due to the blocking of the first arc-shaped guiding mechanism 101 of the base and the second arc-shaped guiding mechanism 501 of the base, the direction of the hydraulic support gradually changes from being perpendicular to the pushing oil cylinder 13 to being parallel to the pushing oil cylinder 13, achieving the purpose of the movement and orientation adjustment of the hydraulic support. Finally, the traction chain at the end of the platform is connected to the hydraulic support pushing jack through the fixed chain box 28, and by operating the hydraulic support pushing jack, the forward movement of the hydraulic support is realized; after the hydraulic support is retracted in place, it is transported by a support carrier vehicle.

[0037] The fixed chain box 28 is used to fix the traction chain at the end of the platform to realize the forward movement of the hydraulic support after orientation adjustment. The auxiliary oil cylinder 29 is used to assist in adjusting the position and direction when the hydraulic support moves forward. The connecting rod 31 is used to connect with other devices (the shield pushing oil cylinder) to realize the overall movement of the new hydraulic support traction and orientation adjustment device.

[0038] The use of the connecting rod of the hydraulic support traction and orientation adjustment device in this application can effectively increase the safety factor of roof management in the retraction working face. The base guide pulley can effectively change the direction of the force, reduce the use of auxiliary orientation adjustment devices, and realize the one-time traction and orientation adjustment of the hydraulic support. The use of the fixed chain box effectively replaces other devices for traction and moving the support, and at the same time increases the support loading and transportation method.

[0039] The technical effects of the hydraulic support traction and orientation adjustment device in this application:

[0040] 1. In view of the complex underground installation conditions, the structural composition is optimized, the operation process is simplified, and it is independently researched, designed, with a simple structure, convenient to use, strong practicability, and easy to disassemble, operate and maintain.

[0041] 2. The cooperation of the single-piece pushing oil cylinder with the oil cylinder guiding pulley and the base guiding pulley realizes the extraction and orientation adjustment of the hydraulic support, avoiding problems such as multiple installation processes, large occupied space and cumbersome operation of multiple traction arms.

[0042] 3. The traction chain is used instead of the steel wire rope for traction connection, meeting the requirements of traction force and safety factor at the same time.

[0043] 4. A fixed chain box is provided, which can quickly and conveniently realize the forward movement of the hydraulic support after orientation adjustment.

[0044] 5. It can realize the joint operation with the support carrier vehicle, and can complete the withdrawal and transportation operations of the hydraulic support at one time.

[0045] The embodiments described above are only descriptions of the preferred embodiments of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
