Description

Technical Field

[0001] This utility model relates to the field of single hydraulic prop technology, and specifically to a single hydraulic prop dismantling device. Background Technology

[0002] A single hydraulic prop is a retractable prop that uses liquid pressure to generate working resistance and achieves lifting and unloading. Single hydraulic props are divided into suspended type, double telescopic suspended type, DN internal injection type and fiberglass single hydraulic prop. They are mainly used for support of ordinary mechanized coal mining faces, and can also be used for local areas of fully mechanized mining faces, such as end or temporary support.

[0003] Currently, due to the dampness in the well, individual hydraulic props are prone to severe corrosion, making manual disassembly impossible. Therefore, specialized disassembly devices are often required. However, existing devices often use clamps and bolts to constrain and fix the middle of the individual hydraulic prop. The clamps have poor compatibility with props of different diameters, which can easily cause displacement and make it difficult to effectively ensure the stable fixation of the individual hydraulic prop. Furthermore, this reduces the centering accuracy and results in poor performance. Therefore, this application proposes a disassembly device for individual hydraulic props. Utility Model Content

By setting up a lifting mechanism and a positioning mechanism, the lifting mechanism, in conjunction with a support seat with a V-groove and a lifting component, can support and lift the single hydraulic prop and adjust its height, ensuring that the axis of the single hydraulic prop coincides with the reference axis of the first chuck, the second chuck, and the positioning mechanism, thereby ensuring centering and positioning. Furthermore, through the positioning mechanism combined with multiple sets of staggered clamping ring structures and an adaptive opening and closing structure design, the device can effectively achieve clamping and positioning of the single hydraulic prop, ensuring clamping stability. It can also flexibly adapt to single hydraulic props of different diameters within a certain range, significantly improving the versatility and applicability of the device, thus solving the aforementioned shortcomings in the technology.

Detailed Implementation

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figures 1-4The single hydraulic prop removal device shown includes a machine tool 1. A first chuck 2 is mounted on one end of the top side of the machine tool 1 via a bracket, and a second chuck 3 is mounted on the other end of the top side of the machine tool 1 via a bracket. A prop-pulling cylinder 4 is located on the top of the machine tool 1 near the second chuck 3. The output end of the prop-pulling cylinder 4 is connected to the second chuck 3. The first chuck 2 and the second chuck 3 can respectively clamp onto both ends of the single hydraulic prop, and in conjunction with the prop-pulling cylinder 4, can pull off the end cap, large prop, and small prop of the single hydraulic prop. A lifting mechanism is located on the top of the machine tool 1 and between the first chuck 2 and the second chuck 3. The lifting mechanism includes two symmetrically arranged... The support base 6 has a V-groove at its top and a lifting assembly between its bottom and the machine tool 1. The lifting assembly is used to adjust the height of the support base 6. Specifically, the lifting assembly includes cylinders 5 symmetrically arranged at both ends of the bottom side of the support base 6. The bottom ends of the cylinders 5 are embedded in the machine tool 1. Thus, by setting the support base 6 with the V-groove, the single hydraulic support can be supported and lifted. Furthermore, by setting the lifting assembly, the lifting assembly, together with the cylinders 5, can adjust the height of the support base 6 to ensure that the axis of the single hydraulic support coincides with the reference axis of the first chuck 2, the second chuck 3, and the positioning mechanism, thereby ensuring centering and positioning.

[0017] In one specific embodiment of this utility model, a positioning mechanism is also provided between the two support seats 6, and the positioning mechanism includes a fixed frame 7. The bottom end of the fixed frame 7 is fixedly connected to the machine tool 1, and the top side of the fixed frame 7 is symmetrically connected to multiple sets of first fixed arms 9 and second fixed arms 11 via a rotating shaft. The top ends of the first fixed arms 9 and the second fixed arms 11 are symmetrically connected to first clamping rings 10 and second clamping rings 12, respectively. The first clamping rings 10 and the second clamping rings 12 are staggered. The inner sides of the first clamping rings 10 and the second clamping rings 12 are provided with anti-slip ridges. Based on this, the stability during clamping can be greatly enhanced by the anti-slip ridges. A movable column 8 is movably installed on the inner side of the fixed frame 7, and the first fixed arms 9 and the second fixed arms 11 are rotatably connected to the movable column 8 via a rotating shaft. A drive assembly is provided on the fixed frame 7, and the drive assembly is used to control the movement of the movable column 8.

[0018] By setting a positioning mechanism, the single hydraulic support is placed between multiple sets of opening and closing first clamping rings 10 and second clamping rings 12 on the positioning mechanism. By activating the drive assembly, the drive assembly can drive the movable column 8 to move stably within the fixed frame 7. Then, the movable column 8 can pull multiple sets of connecting arms 13 on both sides to move, so that the connecting arms 13 simultaneously drive the first fixed arm 9 and the second fixed arm 11 to rotate. This allows the multiple sets of symmetrical first clamping rings 10 and second clamping rings 12 to move inward in a synchronized manner. Since the first clamping rings 10 and second clamping rings 12 are staggered, they can respectively abut against both sides of the single hydraulic support, thereby effectively achieving the clamping and positioning of the single hydraulic support and ensuring clamping stability. Furthermore, through the interlocking clamping structure and adaptive opening and closing structure design, it can flexibly adapt to single hydraulic props of different diameters within a certain range, significantly improving the versatility of the device and its applicability to various scenarios.

[0019] In this embodiment, the drive assembly includes a threaded rod 14 rotatably connected to the fixed frame 7 via a bearing, and a movable column 8 connected to the outside of the threaded rod 14 via a threaded connection. The bottom end of the threaded rod 14 extends to the outside of the fixed frame 7 and is provided with a drive motor 15, which is embedded in the machine tool 1. Based on this, by starting the drive motor 15, the drive motor 15 can drive the threaded rod 14 to rotate, and then the threaded rod 14 can drive the movable column 8 to move within the fixed frame 7. This allows the movable column 8 to drive the first fixed arm 9 and the second fixed arm 11 to rotate via the connecting arm 13, thereby controlling the first clamping ring 10 and the second clamping ring 12 to converge inward or expand outward.

[0020] Furthermore, limit blocks 16 are symmetrically arranged at both ends of the movable column 8, and limit grooves 17 matching the limit blocks 16 are provided on both sides of the inside of the fixed frame 7. By setting the limit blocks 16 and the limit grooves 17, when the drive component drives the movable column 8 to move, the movable column 8 can drive the limit blocks 16 to slide along the limit grooves 17, thereby further supporting and limiting the movable column 8, which greatly ensures the stable lifting and lowering of the movable column 8.

[0021] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
