Description

Technical Field

[0001] This utility model relates to the field of coal mine engineering technology, specifically to a hydraulic support adjustment device. Background Technology

[0002] With the construction of modern mines and the continuous improvement of coal mining mechanization, the non-coal production time occupied by the installation and dismantling of equipment in fully mechanized mining faces is getting longer and longer, and safety hazards are also increasing. Therefore, the safe and efficient installation and dismantling of equipment in fully mechanized mining faces is becoming increasingly important for the continuous, stable and healthy development of mines.

[0003] Existing hydraulic support retraction equipment is too large in overall size, has a complex structure, and is difficult to disassemble, assemble, and transport. This makes it inefficient in coal mine environments where transport roadways and yard roadways are severely deformed, increasing the labor intensity of underground workers. After the existing transfer device drags the hydraulic support to the workbench, it is necessary to rotate the hydraulic support by 90° during subsequent loading and transfer so that the hydraulic support arm is placed horizontally on the transfer vehicle. This process relies on steel cable pulling and takes a lot of time, resulting in low efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, a hydraulic support relocation device is provided. This technical solution solves the problems mentioned in the background art, such as the existing hydraulic support retraction equipment being too large in overall size, complex in structure, and difficult to disassemble, assemble, and transport, resulting in low efficiency in coal mine environments with severe deformation in transport roadways and yard roadways, and increasing the labor intensity of underground workers. Furthermore, existing relocation devices, after dragging the hydraulic support to the workbench, require rotating the hydraulic support by 90° during subsequent loading and transfer, so that the hydraulic support arm is placed horizontally on the transfer vehicle. This process relies on steel cables and is time-consuming and inefficient.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A hydraulic support adjustment device includes a main platform, a transition platform at the rear of the main platform, a left side of the transition platform fixedly connected to a sloping shovel plate via an arc platform, a traction arm at the right side of the transition platform, and a support device at the right side of the transition platform. A bottom-lifting outrigger is located inside the rear of the main platform, an adjustment device is located on the left side of the main platform, a crawling box is located at the bottom of the main platform, and a hydraulic system is installed inside the main platform.

[0007] Preferably, the hydraulic system includes hydraulic control components and hydraulic auxiliary components in addition to hydraulic cylinders.

[0008] Preferably, the support device can extend and retract to support the tunnel roof, preventing platform displacement.

[0009] Preferably, the arc platform has an arc-shaped guide rail structure, which can force the support to rotate 90°.

[0010] Preferably, the crawling box moves by alternating extension and retraction of a hydraulic cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By setting up a hydraulic system as the power source, combined with the traction function of the traction arm and the arc-shaped guide rail structure of the arc platform, the automated adjustment and transfer of hydraulic supports from the working face to the platform is realized. This not only improves work efficiency but also reduces manual intervention and operational risks. Secondly, by setting up a support device, the design of which allows for extension and retraction adjustment according to the roadway roof conditions, a stable support force is provided, effectively preventing platform displacement during operation and ensuring operational safety and stability. This provides a reliable guarantee for the adjustment and transfer of hydraulic supports. Furthermore, by setting up a hydraulic system, through hydraulic levers and integrated hydraulic control and auxiliary components, the coordinated work of each mechanism ensures the precision of the movement of the device, improving operational efficiency and safety, and making the adjustment and transfer of hydraulic supports smoother. Finally, by setting up a crawler box, the alternating extension and retraction of hydraulic cylinders in the crawler box achieves self-movement. This function allows the device to adjust its position autonomously during operation without the need for external traction equipment, which not only improves operational flexibility but also reduces dependence on external resources, further enhancing operational efficiency.

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Reference Figure 1-3As shown, a hydraulic support adjustment device includes a main platform 1, a transition platform 2 is provided on the rear side of the main platform 1, and the left side of the transition platform 2 is fixedly connected to the inclined shovel plate 4 through an arc platform 3. The arc platform 3 has an arc-shaped guide rail structure, which can forcibly guide the support to rotate 90°.

[0020] In this scheme, a transition platform 2 is set behind the main platform 1, and the arc platform 3 on the left side of the transition platform 2 is fixedly connected to the inclined shovel plate 4, which realizes the effect of forcibly guiding the hydraulic support to rotate 90° during the traction process, thereby meeting the needs of loading and transporting the hydraulic support.

[0021] Reference Figure 1-3 As shown, a traction arm 5 is provided on the right side of the transition platform 2, and a support device 7 is also provided on the right side of the transition platform 2. The support device 7 can extend and retract to support the roof of the roadway and prevent the platform from shifting.

[0022] In this scheme, the hydraulic support is connected to the traction arm 5 and pulled, which realizes the smooth transfer of the hydraulic support from the working face to the adjustment platform, greatly reducing the labor intensity of the operators and improving work efficiency. Secondly, the telescopic support of the jacking device 7 supports the roadway roof, effectively preventing the platform from shifting during the traction process and ensuring the safety of the operation.

[0023] Reference Figure 1-3 As shown, a lifting support leg 6 is provided inside the rear side of the main platform 1, and an adjustment device 8 is provided on the left side of the main platform 1.

[0024] In this solution, by adjusting the height of the lifting outrigger 6, it is ensured that the heavy object can be smoothly transferred through the machine body to the hydraulic support retraction forklift, which further improves the flexibility and efficiency of the operation. Secondly, through the function of the deviation adjustment device 8, the stability of the hydraulic support during the transfer process is ensured, avoiding safety hazards caused by deviation.

[0025] Reference Figure 1-3 As shown, a crawling box 9 is provided at the bottom of the main platform 1. The crawling box 9 moves by alternating extension and retraction of hydraulic cylinders.

[0026] In this solution, the crawling box 9 moves itself by alternating extension and retraction of hydraulic cylinders, realizing the self-moving function of the hydraulic support adjustment device without the need for additional auxiliary equipment, further improving the convenience and efficiency of operation.

[0027] Reference Figure 1-3 As shown, the main platform 1 is equipped with a hydraulic system 10, which includes hydraulic control components and hydraulic auxiliary components in addition to hydraulic cylinders.

[0028] In this scheme, in addition to the hydraulic cylinder, the hydraulic system 10 also includes hydraulic control elements and hydraulic auxiliary elements. The control valve group of the hydraulic control element, the hydraulic control check valve, and the pipe joints and hoses of the hydraulic auxiliary elements are precisely controlled by the hydraulic system 10 to realize the extension and retraction movement of the hydraulic cylinder, thereby controlling the action of the entire transfer device and ensuring the accuracy and reliability of the operation process.

[0029] The working principle of this utility model is as follows: First, after the traction arm 5 is connected to the hydraulic support, the hydraulic support is smoothly transferred from the working face to the adjustment platform through the traction action. During this process, the support device 7 extends and retracts to support the roof of the roadway, preventing platform displacement and ensuring the safety of the transfer process. Second, by adjusting its height, it is ensured that the heavy object can be smoothly transferred through the machine body to the hydraulic support retraction forklift, improving the flexibility and efficiency of the operation. Third, the deviation device 8 ensures the stability of the hydraulic support during the transfer process, preventing safety hazards caused by deviation. Then, the self-moving function is achieved by the alternating extension and retraction of the hydraulic cylinder in the crawling box 9, without the need for additional auxiliary equipment, improving the convenience and efficiency of the operation. Finally, through the hydraulic control elements and hydraulic auxiliary elements in the hydraulic system 10, the extension and retraction of the hydraulic cylinder is realized through the precise control of the hydraulic system 10, thereby controlling the action of the entire adjustment device and ensuring the accuracy and reliability of the operation process.
