Description

Technical Field

[0001] This utility model relates to the field of hydraulic support technology, and in particular to a limiting device for hydraulic supports used in mining equipment. Background Technology

[0002] In mining operations, hydraulic supports are used to reinforce mine tunnels and prevent them from collapsing. The hydraulic support control console controls various actions of the hydraulic support, including lifting, moving, pushing, balancing, and extending / retracting the front beam. Its reliability and safety are of paramount importance.

[0003] Chinese Patent Publication No. CN222596108U discloses "A hydraulic support limiting device for mining equipment". The technical solution includes a control console, on which a limiting box is fixedly connected. The limiting box has several first and second sliding grooves. The control console is provided with several control rods that penetrate the first sliding grooves. The inner side of the limiting box has several locking grooves on one side of the second sliding groove.

[0004] This hydraulic support limiting device for mining equipment uses a locking box and spring structure. When the control lever needs adjustment, pressing down on the lever pushes the mounting block to compress the spring. The mounting block then moves the locking block downwards, disengaging it from the locking groove, thus unlocking the control lever. After the control lever is operated, releasing the lever and spring pushes the mounting block upwards, causing the locking block to enter the locking groove and lock the control lever. Locking can be performed separately after adjustment, making it more convenient and avoiding problems caused by forgetting to lock or neglecting to lock for convenience, which could affect the operation of the hydraulic support.

[0005] However, this design has many drawbacks in practical applications. On the one hand, traditional locking box designs usually require the operation to be divided into two or more parts. Operators need to operate each part sequentially to complete the rotation of the limit control lever, which is cumbersome and inefficient. In the complex operating environment and time-sensitive situations of mining equipment, this cumbersome operation method undoubtedly increases the difficulty of operation and the operation time, reducing the overall practicality of the equipment.

[0006] On the other hand, in traditional limit devices, the connection between the limit box and the control console is mostly fixed or difficult to disassemble quickly. When the internal components of the control console malfunction and need to be repaired, the process of disassembling the limit box is complicated and time-consuming, which seriously affects the efficiency of equipment maintenance, increases equipment downtime, and consequently affects the normal operation and production progress of mining equipment. Therefore, we provide a hydraulic support limit device for mining equipment. Utility Model Content

[0007] To address the aforementioned problems, this utility model proposes a hydraulic support limiting device for mining equipment, which more accurately solves the problems mentioned in the background art.

[0008] This utility model is achieved through the following technical solution:

[0009] The utility model proposes a hydraulic support limiting device for mining equipment, including a control console and a limiting box plate. The outer periphery of the limiting box plate is provided with an arc-shaped sliding groove. A U-shaped block is fixedly installed on the inner bottom wall of the control console. A control rod is rotatably connected to the U-shaped block through a rotating shaft. A rectangular groove is provided at the upper end of the control rod. A connecting rod is inserted into the inner wall of the rectangular groove. A control rod is fixedly welded to the upper end of the connecting rod. An elastic component connects the rectangular groove and the connecting rod.

[0010] A limiting component is connected between the control rod two and the limiting box plate;

[0011] A disassembly and assembly mechanism is connected between the control console and the limiting box plate;

[0012] The elastic component includes a rectangular through groove formed in the inner sidewall of a rectangular groove, a vertical support rod fixedly connected between the two end walls of the rectangular through groove, a spring sleeved around the vertical support rod, and a sliding sleeve block slidably sleeved around the vertical support rod.

[0013] Furthermore, the disassembly and assembly mechanism includes a second limiting insertion hole opened on the side of the limiting box plate and a plug-in post inserted on the side of the control console. One end of the plug-in post is fixedly connected to a limiting plate, and the other end of the plug-in post is fixedly connected to a connecting plate. The connecting plate is fixedly connected to the limiting plug-in post relative to the side surface of the control console, and a second spring is sleeved around the plug-in post.

[0014] Furthermore, the limiting component includes a limiting insertion hole one opened in the inner wall of the limiting box plate and a fixing block fixedly connected to the surface of the control rod two, wherein a limiting insertion rod is fixedly connected to the upper surface of the fixing block.

[0015] Furthermore, the sliding sleeve is slidably connected to the inner wall of the rectangular through groove, and the opposite surfaces of the two sliding sleeves are fixedly connected to the two side surfaces of one of the plug-in rods.

[0016] Furthermore, the upper end of the limiting rod is inserted into the inner wall of the limiting hole one, and the inner diameter of the limiting hole one is adapted to the outer diameter of the limiting rod.

[0017] Furthermore, the end of the limiting plug is inserted into the inner wall of the limiting hole two, and the inner diameter of the limiting hole two is compatible with the outer diameter of the limiting plug.

[0018] Furthermore, the upper end of the first spring is fixedly connected to the lower end surface of the sliding sleeve block, and the lower end of the first spring is fixedly connected to the end wall of the rectangular through groove.

[0019] Furthermore, one end of the second spring is fixedly connected to the inner wall of the control console, and the other end of the second spring is fixedly connected to the surface of the limiting plate.

[0020] The beneficial effects of this utility model are:

[0021] This invention replaces the original matching locking box with a single control lever designed in two parts, with elastic components and limiting parts in between. This allows the entire unit to rotate the control lever simply by pressing the force onto the second control lever, thus eliminating the cumbersome operation of two parts and improving the overall practicality.

[0022] This utility model, by setting up a disassembly and assembly mechanism, allows the limiting box plate to be quickly assembled and disassembled with the control console, thereby facilitating the rapid inspection and maintenance of the internal components of the control console and achieving better usage results.

[0029] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0030] Example

[0031] like Figures 1-5 As shown in the figure, an embodiment of the present invention discloses a hydraulic support limiting device for mining equipment, including a control console 1 and a limiting box 2. An arc-shaped groove 3 is formed on the periphery of the limiting box 2 to accommodate the movement trajectory of the limiting device. A U-shaped block 4 is fixedly installed on the inner bottom wall of the control console 1. The U-shaped block 4 is rotatably connected to a control rod 5 via a rotating shaft, allowing the control rod 5 to rotate around the shaft. A rectangular groove 6 is formed at the upper end of the control rod 5. A connecting rod 7 is inserted into the inner wall of the rectangular groove 6, allowing the connecting rod 7 to move to a certain extent within the rectangular groove 6. A control rod 8 is fixedly welded to the upper end of the connecting rod 7, connecting the control rod 5 and the control rod 8. An elastic component is connected between the rectangular groove 6 and the connecting rod 7. The elastic component specifically includes a rectangular through groove 9 formed on the inner side wall of the rectangular groove 6, a vertical support rod 10 fixedly connected between the two end walls of the rectangular through groove 9, a spring 11 sleeved around the vertical support rod 10, and a sliding sleeve block 12 slidably sleeved around the vertical support rod 10. When the plug rod 7 moves within the rectangular groove 6, it causes the sliding sleeve 12 to slide on the upright rod 10, thereby compressing or stretching the spring 11 to achieve an elastic effect.

[0032] With the above-mentioned structural arrangement, control rod 1 5 can rotate on U-shaped block 4, and control rod 2 8 is connected to control rod 1 5 through plug rod 7. There is an elastic component between the two. During the operation of the limit device, the elastic component can play a buffering and adjustment role, ensuring the stability and flexibility of the limit device operation.

[0033] Furthermore, the disassembly and assembly mechanism includes a second limiting insertion hole 16 on the side of the limiting box plate 2, and a plug-in post 17 inserted on the side of the control console 1. One end of the plug-in post 17 is fixedly connected to the limiting plate 18, and the other end is fixedly connected to the connecting plate 19. The connecting plate 19 is fixedly connected to the limiting insertion post 20 on the side surface of the control console 1, and a second spring 21 is sleeved around the plug-in post 17. When the limiting box plate 2 needs to be installed, the limiting plate 18 is pulled outward, which moves the plug-in post 17 and the connecting plate 19 outward, compressing the second spring 21. After the limiting box plate 2 is placed in the appropriate position, the limiting plate 18 is released. Under the elastic force of the second spring 21, the limiting insertion post 20 is inserted into the second limiting insertion hole 16, thus connecting the limiting box plate 2 to the control console 1. When disassembly is required, the limiting plate 18 is pulled outward again, causing the limiting insertion post 20 to disengage from the second limiting insertion hole 16, and the limiting box plate 2 can be removed.

[0034] The disassembly and assembly mechanism allows for convenient and quick installation and disassembly of the limit box 2 and the control console 1, facilitating equipment maintenance and replacement.

[0035] Furthermore, the limiting component includes a limiting insertion hole 13 on the inner wall of the limiting box plate 2, a fixing block 14 fixedly connected to the surface of the control rod 8, and a limiting insertion rod 15 fixedly connected to the upper surface of the fixing block 14. When the control rod 8 moves to the appropriate position, the limiting insertion rod 15 will be inserted into the limiting insertion hole 13 to limit the control rod 8 and prevent it from continuing to move, thereby ensuring the stability and accuracy of the limiting device.

[0036] The limiting component effectively restricts the movement range of the control lever 8, ensuring that the limiting device functions in a specific position and improving the reliability of equipment operation.

[0037] Furthermore, the sliding sleeve 12 is slidably connected to the inner wall of the rectangular through groove 9, and the opposing surfaces of the two sliding sleeves 12 are fixedly connected to the two side surfaces of a plug rod 7. When the plug rod 7 moves within the rectangular groove 6, it will cause the two sliding sleeves 12 to slide synchronously within the rectangular through groove 9, making the movement of the plug rod 7 more stable, while ensuring that the elastic component can function properly.

[0038] This connection method establishes a stable connection between the plug rod 7 and the elastic component, ensuring that the elastic component can provide stable elastic force during the movement of the plug rod 7, thereby improving the operational stability of the limiting device.

[0039] Furthermore, the upper end of the limiting rod 15 is inserted into the inner wall of the limiting hole 13, and the inner diameter of the limiting hole 13 is compatible with the outer diameter of the limiting rod 15. When the limiting rod 15 is inserted into the limiting hole 13, the two fit together tightly, which can effectively limit the movement of the control rod 8, prevent it from shaking or shifting, and ensure the limiting effect of the limiting device.

[0040] The appropriate diameter design ensures good fit between the limiting rod 15 and the limiting hole 13, improving the limiting reliability of the limiting component and ensuring that the limiting device can work accurately and stably.

[0041] Furthermore, the end of the limiting pin 20 is inserted into the inner wall of the limiting socket 16, and the inner diameter of the limiting socket 16 is compatible with the outer diameter of the limiting pin 20. When the limiting pin 20 is inserted into the limiting socket 16, the two are tightly joined, which can firmly connect the limiting box 2 and the control console 1, ensuring the stability of the equipment during operation.

[0042] The adaptive diameter design ensures a reliable connection between the limiting pin 20 and the limiting hole 16, improving the connection strength of the disassembly and assembly mechanism and ensuring that the limiting box plate 2 and the control console 1 will not easily separate during equipment operation.

[0043] Furthermore, the upper end of spring 11 is fixedly connected to the lower end surface of sliding sleeve 12, and the lower end of spring 11 is fixedly connected to the end wall of rectangular through groove 9. When sliding sleeve 12 slides in rectangular through groove 9, it will compress or stretch spring 11. The elastic force generated by spring 11 will act on sliding sleeve 12, thereby buffering and adjusting the movement of plug rod 7.

[0044] This connection method allows the spring 11 to function properly in the elastic component, providing appropriate elastic force for the movement of the plug rod 7, and ensuring the stability and flexibility of the limiting device during operation.

[0045] Furthermore, one end of spring 21 is fixedly connected to the inner wall of the control console 1, and the other end of spring 21 is fixedly connected to the surface of the limiting plate 18. When the limiting plate 18 is pulled outward, spring 21 is stretched, and spring 21 generates elastic force; after the limiting plate 18 is released, the elastic force of spring 21 will cause the limiting plate 18 to return to its original position, thereby driving the limiting pin 20 to be inserted into the limiting hole 16, realizing the connection between the limiting box plate 2 and the control console 1.

[0046] This connection method enables the second spring 21 to function properly in the disassembly and assembly mechanism, providing power for the insertion and removal of the limit pin 20, ensuring the normal operation of the disassembly and assembly mechanism, and facilitating the installation and removal of the limit box plate 2.
