Description

Technical Field

[0001] This utility model belongs to the field of hydraulic support technology, and in particular relates to a hydraulic support adjustment device. Background Technology

[0002] In coal mining equipment, hydraulic supports are the core equipment of the longwall mining face. They are mainly used to control the pressure in the mine during coal mining and provide support.

[0003] As a crucial structural component of hydraulic supports, the top support plate bears the main pressure from the roof. As mining operations continue, the hydraulic supports need to be moved deeper into the mine. During this process, the protective positions of the hydraulic supports are prone to localized loosening, which poses significant safety hazards during fully mechanized coal mining. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a hydraulic support adjustment device. This device can continuously and stably support the upper wall of the mine to prevent hidden dangers, flexibly adjust the support to adapt to different environments, support coal mining operations in parallel to improve efficiency, and can be easily moved while always maintaining support to ensure operational safety.

[0005] The technical solution adopted by this utility model is as follows: A hydraulic support adjustment device includes a side support rod and a hydraulic adjustment assembly. The side support rod is installed on the bottom surface of the mine tunnel, and the hydraulic adjustment assembly is disposed on the side wall of the side support rod. Multiple sets of hydraulic adjustment assemblies are provided, and the multiple sets of hydraulic adjustment assemblies are arranged in a linear array. The hydraulic adjustment assembly includes a T-shaped slide and a support body. The T-shaped slide is disposed on the side wall of the side support rod, and the support body is slidably connected to the T-shaped slide.

[0006] Furthermore, the support body includes a base, a supporting hydraulic cylinder, a top support plate, an auxiliary hydraulic cylinder, and a side support plate. A sliding groove is formed on the lower bottom wall of the base, a groove is formed on one end of the upper wall of the base, and an inclined groove is formed on the other end of the upper wall of the base. The fixed end of the supporting hydraulic cylinder is located on the groove. One end of the top support plate is hinged to the movable end of the supporting hydraulic cylinder. The fixed end of the auxiliary hydraulic cylinder is located on the inclined groove. One end of the side support plate is connected to the movable end of the auxiliary hydraulic cylinder, and the other end of the side support plate is rotatably connected to the other end of the top support plate.

[0007] Furthermore, an upper sliding groove is provided on the upper wall of the top support plate, and a T-shaped support plate is slidably connected in the upper sliding groove. A control hydraulic cylinder is provided on the T-shaped slide, and the movable end of the control hydraulic cylinder is connected to the bottom wall of the T-shaped support plate.

[0008] Furthermore, the depth of the upper groove is greater than the thickness of the T-shaped support plate.

[0009] Furthermore, the side support rod is connected to an external transmission device.

[0010] The beneficial effects of this utility model after adopting the above structure are as follows:

[0011] 1. Continuous and stable support: Through the coordinated operation of the control hydraulic cylinder, support hydraulic cylinder and auxiliary hydraulic cylinder, as well as the cooperation between the T-shaped support plate and the top support plate, the inner upper wall of the mine can be continuously supported regardless of whether the support body moves or not. This effectively prevents safety hazards caused by local slack in the protection position and provides a safer environment for mine operations.

[0012] 2. Flexible and Adjustable Support: By utilizing the support hydraulic cylinder, auxiliary hydraulic cylinder, and control hydraulic cylinder, the position and state of the top support plate, T-shaped support plate, and side support plate can be flexibly adjusted. Precise support can be provided according to the actual conditions of the upper wall inside the mine, improving the adaptability of the device to different mining environments.

[0013] 3. Facilitates coal mining operations: While the support body provides stable support to the upper wall of the mine, the working face at the end of the side support rod away from the support body can carry out coal mining operations normally. The mined coal can be transported out in a timely manner through the conveying device connected to the side support rod, realizing the parallel operation of support and coal mining operations and improving coal mining efficiency.

[0014] 4. Convenient and efficient mobility: By controlling the base to move along the T-shaped slide and the side support rod and T-shaped slide to move towards the coal mining face, the position of the entire device can be easily and quickly adjusted to adapt to the needs of coal mining work at different stages. During the movement, it can always maintain support for the mine, ensuring the continuity and safety of the operation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0023] like Figures 1-4 As shown, a hydraulic support adjustment device includes a side support rod 1 and a hydraulic adjustment assembly 2. The side support rod 1 is installed on the bottom surface of the mine tunnel, and the hydraulic adjustment assembly 2 is disposed on the side wall of the side support rod 1. Multiple sets of the hydraulic adjustment assembly 2 are arranged in a linear array. The hydraulic adjustment assembly 2 includes a T-shaped slide block 3 and a support body 4. The T-shaped slide block 3 is disposed on the side wall of the side support rod 1, and the support body 4 is slidably connected to the T-shaped slide block 3.

[0024] The support body 4 includes a base 5, a supporting hydraulic cylinder 6, a top support plate 7, an auxiliary hydraulic cylinder 8, and a side support plate 9. A sliding groove 10 is provided on the lower bottom wall of the base 5, a groove 11 is provided on one end of the upper wall of the base 5, and an inclined groove 12 is provided on the other end of the upper wall of the base 5. The fixed end of the supporting hydraulic cylinder 6 is located on the groove 11. One end of the top support plate 7 is hinged to the movable end of the supporting hydraulic cylinder 6. The fixed end of the auxiliary hydraulic cylinder 8 is located on the inclined groove 12. One end of the side support plate 9 is connected to the movable end of the auxiliary hydraulic cylinder 8, and the other end of the side support plate 9 is rotatably connected to the other end of the top support plate 7.

[0025] The upper wall of the top support plate 7 is provided with an upper sliding groove 13, and a T-shaped support plate 14 is slidably connected in the upper sliding groove 13. A control hydraulic cylinder 15 is provided on the T-shaped slide block 3, and the movable end of the control hydraulic cylinder 15 is connected to the bottom wall of the T-shaped support plate 14.

[0026] The depth of the upper groove 13 is greater than the thickness of the T-shaped support plate 14.

[0027] The side support rod 1 is connected to an external transmission device.

[0028] In practical use, in the initial state, the bottom wall of the T-shaped support plate 14 and the inner bottom wall of the upper sliding groove 13 are in contact. Simultaneously, the control hydraulic cylinder 15 and the support hydraulic cylinder 6 are activated. With the cooperation of the auxiliary hydraulic cylinder 8, they jointly control the top support plate 7, the T-shaped support plate 14, and the side support plate 9, ensuring that the upper wall of the top support plate 7 fits against the inner upper wall of the mine, thus supporting the inner upper wall. Then, the hydraulic cylinder 15 is extended, causing the T-shaped support plate 14 to move upwards a certain distance, making its upper wall flush with the upper wall of the top support plate 7, jointly supporting the inner upper wall of the mine. At this time, the end of the side support rod 1 furthest from the support body 4, i.e., the coal mining machine on the working face of the coal mine, operates to mine coal. The mined coal falls onto the conveying device connected to the side support rod 1, which collects... After the coal is transported out of the mine, the supporting hydraulic cylinder 6 and the auxiliary hydraulic cylinder 8 shorten simultaneously, and the top support plate 7 temporarily moves away from the inner upper wall of the mine. The inner upper wall of the mine is temporarily supported by the T-shaped support plate 14. At the same time, the control base 5 moves along the T-shaped slide 3 towards the side support rod 1, and the supporting hydraulic cylinder 6 and the auxiliary hydraulic cylinder 8 reset. Then, the control hydraulic cylinder 15 shortens, so that the bottom wall of the T-shaped support plate 14 and the inner bottom wall of the upper slide groove 13 are in contact again. Then, the control side support rod 1 and the T-shaped slide 3 move the same distance towards the working face of the coal mine, and the control hydraulic cylinder 15 is reset again. At this time, the inner upper wall of the mine is supported by the top support plate 7 and the T-shaped support plate 14, ensuring that the inner upper wall of the mine is supported regardless of whether the support body 4 moves, preventing the occurrence of safety hazards caused by local loosening of the protective position.

[0029] The above is the overall workflow of this utility model. Simply repeat these steps the next time you use it.
