Description

Technical Field

[0001] This utility model relates to the field of general downhole equipment, and in particular to a support support pulling device. Background Technology

[0002] According to the layout of the supports at the coal mining face, in order to strengthen the support strength at both ends of the working face, support supports are installed at the coal mining ends to support the roof. However, the support supports cannot be connected to the scraper conveyor chute, which makes it difficult to move the supports.

[0003] The conventional approach in existing technology is to use individual hydraulic props supported by fixed foundations such as the roadway sidewalls to move the support frame. However, this method has many drawbacks, especially the need for additional fixed foundations; even when supported by the roadway sidewalls, the individual hydraulic props can only move at an angle during the movement, meaning the support frame is moved at an angle; the process of moving the support frame into place often requires multiple adjustments, resulting in a cumbersome operation and compromised safety. Currently, there is a lack of corresponding solutions to these problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a support support pulling device that is simple in structure, stable and reliable, safe to use, and especially able to improve the support displacement efficiency.

[0005] The equipment includes a pressure plate, which is the basic assembly component of the equipment;

[0006] The pressure plate is provided with a support assembly slot; the support assembly slot is used to assemble a single hydraulic support.

[0007] A hydraulic cylinder is connected to one side of the pressure plate;

[0008] One end of the hydraulic cylinder is mounted on the pressure plate, and the other end is equipped with a bracket connection mechanism.

[0009] The effect achieved in this way is that the pulling action of the support bracket is realized by hydraulic cylinders.

[0010] That is, before the support is displaced, the hydraulic cylinder piston is in the extended state. In this state, the hydraulic single support is placed into the support assembly slot and extends upward to the top plate to form a fixed pressure plate; the hydraulic cylinder retracts, driving the support to move in the direction of hydraulic cylinder retraction.

[0011] The beneficial effects of this invention are that it solves the problem of inconvenient displacement of downhole support supports in existing technologies. By cooperating with a pressure plate and a single hydraulic prop, a pull-out foundation is quickly established, and the support support is efficiently transferred using this foundation. In other words, the flexible arrangement of the pressure plate and the single hydraulic prop allows the hydraulic support to be moved in any direction, thereby achieving the effect of rapid relocation of the support support. Furthermore, the equipment has a simple structure, low cost, and low maintenance cost, making it highly valuable for safe promotion. Attached Figure Description

[0017] Reference Figure 1 , Figure 2 The support bracket pulling device of this utility model includes a pressure plate 1, which is the assembly base component of the device.

[0018] A support assembly slot 11 is provided on the pressure plate 1; the support assembly slot 11 is used to assemble a single hydraulic support.

[0019] A hydraulic cylinder 3 is provided on one side of the pressure plate 1;

[0020] One end of the hydraulic cylinder 3 is mounted on the pressure plate 1, and the other end is equipped with a bracket connecting mechanism 4.

[0021] Furthermore, the pressure plate 1 is provided with a plurality of support mounting slots 11 arranged in a uniform array.

[0022] Preferably, there are at least four support mounting slots 11.

[0023] The effect achieved is to strengthen the fixing effect of pressure plate 1.

[0024] Furthermore, the pressure plate 1 is in the form of a rectangular flat plate, and the support assembly groove 11 is a thick-walled round tube integrally formed on the pressure plate 1; multiple reinforcing ribs are also provided between the thick-walled round tube and the pressure plate 1.

[0025] The effect achieved is to improve the assembly stability between the single hydraulic support and the pressure plate 1.

[0026] Furthermore, a flexible connector 2 is provided between the pressure plate 1 and the hydraulic cylinder 3.

[0027] Preferably, the flexible connector 2 is a chain.

[0028] This achieves the effect of facilitating the overall fixed assembly of the equipment.

[0029] Furthermore, the bracket connection mechanism 4 is a connection latch.

[0030] Preferably, the support bracket is connected by multiple chains and connected to the hydraulic cylinder 3 by a connecting lock.

[0031] Preferably, the support bracket can also be directly fixed to the hydraulic cylinder 3.

[0032] This achieves the effect of facilitating rapid assembly.

[0033] In use, the pulling action of the support bracket is achieved by hydraulic cylinder 3. That is, before the bracket is displaced, the piston of hydraulic cylinder 3 is in the extended state. In this state, the hydraulic single prop is placed into the prop assembly groove 11 and extends upward to the top plate, forming a fixed pressure plate 1. When hydraulic cylinder 3 retracts, it drives the support bracket to move in the direction of hydraulic cylinder 3 retraction. In other words, based on the flexible arrangement of pressure plate 1 and single hydraulic prop, the hydraulic bracket can be displaced in any direction, thereby achieving the effect of quickly moving the support bracket.
