[0036] like Figure 1 and 2 As shown, this application embodiment provides a rigid connection device for preventing the collapse of a single hydraulic prop in a coal mine, including multiple mounting rods 1, a connecting component 2 between adjacent mounting rods 1, multiple sliding components 3 movably mounted on the mounting rods 1, and a fixing component 4 can be mounted on the sliding component 3. The fixing component 4 is used to fixally connect with the single hydraulic prop 6.
[0037] In use, the operator connects multiple mounting rods 1 together through the connecting component 2 to form a stable overall structure. Then, the fixing component 4 is slid to the position of the single hydraulic support 6 through the sliding component 3. The device is then fixed to the single hydraulic support 6 through the fixing component 4 to achieve the anti-tipping effect.
[0038] This device provides a stable rigid connection, effectively preventing the single hydraulic prop 6 from tipping over in the coal mine and improving the safety of coal mining operations. By setting the connecting component 2, multiple mounting rods 1 can be quickly and easily installed and disassembled. By setting the sliding component 3, the fixing component 4 can be quickly and easily slid to the position of the single hydraulic prop 6, meeting different usage requirements and improving the applicability and flexibility of the device.
[0039] like Figure 1 , 2 As shown in Figures 5 and 6, in this embodiment, the connecting component 2 includes a mounting bracket 21 and a first bolt 22. The mounting rod 1 can be placed inside the mounting bracket 21, and both the mounting rod 1 and the mounting bracket 21 are provided with a first through hole 11. The first bolt 22 can pass through the first through hole 11 and limit and fix the mounting rod 1 inside the mounting bracket 21.
[0040] In use, the mounting rod 1 is placed inside the mounting bracket 21, and the first through hole 11 of the mounting rod 1 is aligned with the first through hole 11 of the mounting bracket 21. Then, the first bolt 22 is passed through the first through hole 11, and the first bolt 22 is used to limit and fix the mounting rod 1 inside the mounting bracket 21, thereby connecting multiple mounting rods 1 together. The connecting assembly 2 enables the mounting rod 1 to be firmly fixed inside the mounting bracket 21, thereby enhancing the stability and reliability of the entire device.
[0041] like Figure 1 , 2 As shown in Figures 5 and 6, in this embodiment, the connecting assembly 2 further includes a first pressure plate 23, a first screw 24, and a guide rod 25. The first pressure plate 23 is disposed inside the mounting bracket 21 and is located above the mounting rod 1. The first pressure plate 23 has a second through hole 26 through which a first bolt 22 passes. The first screw 24 is threaded through the mounting bracket 21 and is rotatably connected to the first pressure plate 23 by a bearing. The guide rod 25 slides through the mounting bracket 21 and is fixedly connected to the first pressure plate 23.
[0042] In use, rotating the first screw 24 causes the first pressure plate 23 to press down until the first pressure plate 23 presses the mounting rod 1 against the mounting bracket 21. This structure makes the mounting rod 1 more securely fixed, and the first screw 24 can be adjusted to accommodate mounting rods 1 of different sizes, improving the versatility and adaptability of the device. The cooperation between the first pressure plate 23 and the guide rod 25 plays a guiding and limiting role for the first pressure plate 23.
[0043] like Figures 1 to 4 As shown, in this embodiment, the sliding component 3 includes a sliding sleeve 31 and a mounting plate 32. The sliding sleeve 31 is slidably sleeved on the mounting rod 1, and the mounting plate 32 is fixedly mounted on the sliding sleeve 31. A fixing component 4 can be installed on the mounting plate 32.
[0044] In use, the sliding sleeve 31 is slid along the mounting rod 1, and the sliding sleeve 31 drives the fixing component 4 to slide to the position of the single hydraulic support 6. The sliding component 3 can move freely on the mounting rod 1, which facilitates the adjustment of the connection position with the single hydraulic support 6. This structure allows the device to flexibly adapt to single hydraulic supports 6 in different positions, improving the flexibility and practicality of the device. The operator can increase or decrease the number of sliding components 3 by slipping the sliding sleeve 31 on the end of the mounting rod 1 to meet different usage needs and improve the applicability and flexibility of the device.
[0045] like Figures 1 to 4 As shown, in this embodiment, the sliding assembly 3 further includes a second pressure plate 33 and a second screw 34. The second pressure plate 33 is disposed inside the sliding sleeve 31 and is located above the mounting rod 1. The second screw 34 is threaded through the sliding sleeve 31 and is rotatably connected to the second pressure plate 33 through a bearing.
[0046] In use, rotating the second screw 34 causes the second pressure plate 33 to press down until the second pressure plate 33 presses the mounting rod 1 against the sliding sleeve 31; this structure allows the sliding sleeve 31 to be firmly fixed on the mounting rod 1, ensuring the stability and reliability of the sliding assembly 3.
[0047] like Figures 1 to 3 As shown, in this embodiment, the fixing component 4 is a clamp 41; in use, the clamp 41 holds the single hydraulic support 6 tightly, so that the single hydraulic support 6 is fixed together with the sliding component 3; the clamp 41 has a simple structure, is easy to install and disassemble, and has a good fixing effect, which can ensure a firm connection between the single hydraulic support 6 and the device.
[0048] like Figure 1 , 2 As shown in Figure 4, in this embodiment, a reinforcement component 5 can be installed on the mounting plate 32. The reinforcement component 5 is used to fix the device to the roadway sidewall. By setting the reinforcement component 5, the device is fixedly connected to the roadway sidewall, which enhances the stability of the device, further improves the anti-tipping effect of the device, and ensures the safety of coal mining operations. Moreover, the reinforcement component 5 can be quickly and easily slid to the target reinforcement position to meet different usage needs and improve the applicability and flexibility of the device.
[0049] like Figure 1 , 2 As shown in Figure 4, in this embodiment, the reinforcement component 5 includes a mounting sleeve 51 and a reinforcement nail 52. The mounting sleeve 51 is fixedly disposed on the mounting plate 32, and the reinforcement nail 52 is slidably disposed within the mounting sleeve 51.
[0050] When in use, slide the sliding sleeve 31 along the mounting rod 1. The sliding sleeve 31 drives the reinforcing component 5 to slide to the target reinforcing position. Then, hammer the reinforcing nail 52 into the side wall of the tunnel to firmly fix the device in the tunnel and improve the anti-tipping effect.
[0051] like Figure 1 , 2 As shown in Figures 5 and 6, in this embodiment, a first handle 27 is fixedly provided at the end of the first screw 24 away from the first pressure plate 23; the first handle 27 facilitates the operator to apply force to rotate the first screw 24, improving ease of use.
[0052] like Figures 1 to 4 As shown, in this embodiment, a second handle 35 is fixedly provided at the end of the second screw 34 away from the second pressure plate 33; the second handle 35 makes it easier for the operator to apply force to rotate the second screw 34, thus improving the ease of use.
[0053] Working principle: When using the anti-tipping rigid connection device for single hydraulic props in coal mines provided in this application, the operator places the mounting rod 1 in the mounting frame 21 and aligns the first through hole 11 of the mounting rod 1 with the first through hole 11 of the mounting frame 21. Then, the first bolt 22 is passed through the first through hole 11 and the first bolt 22 is used to limit and fix the mounting rod 1 in the mounting frame 21. Then, the first handle 27 is rotated to drive the first screw 24 to rotate. The first screw 24 drives the first pressure plate 23 to press down until the first pressure plate 23 presses the mounting rod 1 against the mounting frame 21, thereby connecting multiple mounting rods 1 together to form a stable overall structure.
[0054] Then, slide the sliding sleeve 31 along the mounting rod 1. The sliding sleeve 31 drives the fixing component 4 to slide to the position of the single hydraulic support 6. Then, turn the second handle 35 to drive the second screw 34 to rotate. The second screw 34 drives the second pressure plate 33 to press down until the second pressure plate 33 presses the mounting rod 1 against the sliding sleeve 31. Then, the single hydraulic support 6 is held tightly by the clamp 41, so that the single hydraulic support 6 is fixed together with the sliding component 3 to achieve the anti-tipping effect.
[0055] In addition, slide the sliding sleeve 31 along the mounting rod 1. The sliding sleeve 31 drives the reinforcing component 5 to slide to the target reinforcing position. Then, turn the second handle 35 to drive the second screw 34 to rotate. The second screw 34 drives the second pressure plate 33 to press down until the second pressure plate 33 presses the mounting rod 1 against the sliding sleeve 31. Then, hammer the reinforcing nail 52 into the side wall of the tunnel. The device can then be firmly fixed in the tunnel, improving the anti-tipping effect.
[0056] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
