Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal mining equipment technology, specifically to a hydraulic support retraction device. Background Technology
[0002] Hydraulic supports, as auxiliary support equipment for the retraction of fully mechanized mining equipment in coal mine longwall faces, are a type of support-type support. Installed within the retraction channel, they replace the original wooden stacks and individual support methods, improving safety while reducing channel hardening and deformation, thus creating favorable conditions for rapid face closure and retraction. However, based on current applications, individual hydraulic supports often require temporary replacement or repair due to damage. Repairing a single hydraulic support necessitates its retraction and removal. Currently, this is often done by brute force, dragging and pulling the damaged support out for repair, which is time-consuming, labor-intensive, and inefficient. Therefore, we provide a hydraulic support retraction device to solve this problem. Utility Model Content
[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a hydraulic support retraction device to solve the problems mentioned in the background art.
[0004] To address the problems raised in the background section, this utility model adopts the following technical solution:
[0005] A hydraulic support retraction device includes an adapter plate and a retraction plate;
[0006] The adapter plate is provided with a rotating wheel frame, and a rotating wheel is rotatably installed in the rotating wheel frame. A guide post is installed on one side of the adapter plate, and an overlap plate is provided on the side of the adapter plate near the retraction plate.
[0007] A roller is rotatably mounted on one side of the retraction plate, a vertical rail is mounted on the upper side of the retraction plate, a horizontal rail is mounted between the two vertical rails, ball bearings are mounted on the surfaces of both the vertical and horizontal rails, a winch is mounted on one side of the retraction plate, and an overlap groove is provided on one side of the retraction plate; an overlap shaft is fixedly mounted in the overlap groove.
[0008] The adapter plate is used in conjunction with the overlapping groove on the retraction plate via an overlapping plate;
[0009] As a further improvement of this utility model, the guide post is threadedly installed on one side of the adapter plate, the guide post has a guide wheel in the middle, and a rubber layer is provided on the outer side of the guide wheel.
[0010] As a further improvement of this utility model, the roller includes a rotating shaft, a cover plate is installed on the upper side of the rotating shaft, a rotating wheel is rotatably mounted on the rotating shaft, and a groove is formed on the rotating wheel.
[0011] As a further improvement of this utility model, the output end of the winch is provided with a zipper, which wraps around the roller and then hooks onto the hydraulic support.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This utility model features a reasonable structural design: the design of the adapter plate, retraction plate, and overlapping plate enables the splicing of the retraction device, making it more adaptable to underground spaces and ensuring smoother retraction of the hydraulic support. The design of the roller frame and rollers allows for flexible rotation during retraction, improving operational convenience. The threaded installation of the guide column and the design of the guide wheels provide excellent guidance and stability for the hydraulic support during retraction. The rubber layer on the outer guide wheel of the guide column effectively reduces wear on the support and extends the equipment's service life. Furthermore, the design of the baffle plate and roller groove on the roller enhances the roller's load-bearing capacity, ensuring the stability of the hydraulic support during retraction. The design of the rotating wheel and ball bearings on the underside of the adapter plate and retraction plate makes the entire hydraulic support device more flexible in its movement during retraction, adapting to different working environments. A zipper is installed at the output end of the winch, allowing for simple and quick retraction operation by hooking the hydraulic support around the roller, reducing the labor intensity of workers.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.
[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0023] like Figure 1-5 As shown, a hydraulic support retraction device includes a transition plate 1 and a retraction plate 2;
[0024] The adapter plate 1 is provided with a rotating wheel frame 11, and a rotating wheel 12 is rotatably installed inside the rotating wheel frame 11. A guide post 13 is installed on one side of the adapter plate 1, and an overlapping plate 14 is provided on the side of the adapter plate 1 near the retraction plate 2.
[0025] A roller 22 is rotatably mounted on one side of the retraction plate 2. A vertical rail 21 is mounted on the upper side of the retraction plate 2. A horizontal rail 25 is mounted between the two vertical rails 21. Ball bearings 24 are installed on the surfaces of both the vertical rails 21 and the horizontal rail 25. A winch 23 is mounted on one side of the retraction plate. An overlap groove 26 is provided on one side of the retraction plate 2. An overlap shaft 27 is fixedly mounted in the overlap groove 26.
[0026] The adapter plate 1 is used in conjunction with the overlap groove 27 on the retraction plate 2 via the overlap plate 14;
[0027] The guide post 13 is threaded onto one side of the adapter plate 1. The guide post 13 has a guide wheel in the middle and a rubber layer on the outside of the guide wheel.
[0028] The roller 22 includes a rotating shaft, a cover plate 222 is installed on the upper side of the rotating shaft, and a rotating wheel 221 is rotatably installed on the rotating shaft, with a groove provided on the rotating wheel 221.
[0029] The output end 231 of the winch 23 is equipped with a zipper, which wraps around the roller and then hooks onto the hydraulic support.
[0030] The working principle of this utility model:
[0031] When the hydraulic support needs maintenance, it should be removed from the working face, and the adapter plate 1 should be placed under the hydraulic support. At the same time, the chain on the winch 23 should be hooked around the roller 22 and connected to the reserved hole on the hydraulic support. The operation of the winch 23 will drive the hydraulic support to move onto the adapter plate 1. When half of the hydraulic support has moved onto the adapter plate 1, the chain on the winch 23 should be directly connected to the hydraulic support. Through the action of the guide column 13 and the ball bearing 24, the hydraulic support should be moved and turned onto the retraction plate 2, and then transported for maintenance.
