[0051] To enable those skilled in the art to better understand this application, the technical solution of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0052] The existing arched steel structure support method not only suffers from the problems of cumbersome support height adjustment and inconvenient bolt connection assembly and disassembly, but also lacks structural stability, only supporting the mine roof while requiring additional support for the mine sidewalls, resulting in insufficient overall support for the mine. To improve upon these problems, this application proposes the following embodiments:

[0053] like Figure 1 , Figure 2As shown, this embodiment of a mine reinforcement support device with adjustable function mainly includes: at least two bases 1, at least two support mechanisms 2, at least two arc-shaped support components 27, and splicing components 3. The bases 1 can be base plates, and the two bases 1 are spaced apart to the left and right, thus allowing them to be positioned along the width direction of the mine. For ease of structural description, the length direction of the mine is the front-to-back direction. All components described below will use this direction as the standard for structural description. For example... Figure 3 , Figure 4 , Figure 5 As shown, two support mechanisms 2 are fixedly installed on the upper side of two bases 1 respectively. The support mechanism 2 includes a mounting column 21, which is fixedly installed on the top of the base 1. The upper end of the mounting column 21 is provided with a mounting groove 22. A first pushing member 23 is fixedly installed on the bottom side of the mounting groove 22. The first pushing member 23 can be a cylinder or a hydraulic cylinder.

[0054] like Figure 1 , Figure 3 , Figure 4 As shown, the telescopic end of the first pushing member 23 faces upward, and an assembly block 24 is fixedly installed on the telescopic end. A groove 25 is provided on the top of the assembly block 24, and a slider 26 is slidably assembled inside the groove 25. An arc-shaped support component 27 is provided on the top of the slider 26. The slider 26 and the assembly block 24 are detachably connected by a limiting rod 291. Through holes 28 communicating with the groove 25 are provided on both the left and right sides of the assembly block 24. The slider 26 has transverse holes 29 that match the positions of the two through holes 28. When the slider 26 is inserted into the assembly block 24, the limiting rod 291 passes through the two through holes 28 and the transverse hole 29, thus achieving insertion and installation.

[0055] like Figure 1 , Figure 4 , Figure 6 As shown, a splicing component 3 is provided between the two sliders 26. Specifically, the splicing component 3 includes two fixing blocks 31 and a plug rod 32. The left and right ends of the plug rod 32 are a fixing end and a plug-in end, respectively. The two fixing blocks 31 are fixedly installed on the tops of the two sliders 26, and two arc-shaped support components 27 are installed on the tops of the two fixing blocks 31. The fixing end of the plug rod 32 is fixedly installed on the left side of the right fixing block 31, making the plug rod 32 fixed to the right fixing block 31 and non-removable. A plug hole 33 is provided on the right side of the left fixing block 31, allowing the plug-in end of the plug rod 32 to be inserted and removed into the plug hole 33 of the left fixing block 31. A locking element is also provided on the left fixing block 31, which can lock or release the plug-in end of the plug rod 32, thereby enabling the disassembly of the splicing component 3.

[0056] like Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, a connecting groove 331 is provided at the insertion end of the insertion rod 32, and an assembly groove 34 is provided on the front inner wall of the left fixing block 31. The assembly groove 34 is connected to the insertion hole 33. The locking component in this embodiment includes a displacement block 35 that is slidably assembled inside the assembly groove 34. A spring 36 is fixedly installed on the front side of the displacement block 35, and the front end of the spring 36 is fixedly connected to the inner wall of the assembly groove 34. A pull rod 37 is fixedly installed on the front end of the displacement block 35, and the spring 36 can be sleeved on the pull rod 37. The front end of the pull rod 37 extends out of the left fixing block 31 and is fixedly connected to a handle 38, which can be a round block. An inclined surface is provided on the right side of the rear end of the displacement block 35, which facilitates the insertion of the displacement block 35 into the connecting groove 331 at the insertion end of the insertion rod 32.

[0057] like Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown, when supporting the interior of the mine, the positions of the two mounting columns 21 need to be determined and fixed. First, the arc-shaped support component 27 is installed. During installation, the slider 26 is aligned with the slide groove 25 and inserted. The horizontal hole 29 is aligned with the two through holes 28. Then, the insertion rod 32 is inserted through the through hole 28 and into the horizontal hole 29 to fix the slider 26. Next, the two fixing blocks 31 are spliced. In the initial state, the spring 36 pushes the displacement block 35 into the insertion hole 33. The worker pushes the two arc-shaped support components 27 closer to each other, causing the insertion rod 32 to be inserted into the insertion hole 33. During this period, the insertion end of the insertion rod 32 abuts against the inclined surface of the displacement block 35, thereby generating a pushing force to push the displacement block 35 into the assembly groove 34 and compress the spring 36 until the insertion rod 32 is fully inserted into the insertion hole 33. In this way, the connecting groove 331 is aligned with the assembly groove 34. Under the action of the spring 36, the displacement block 35 is inserted into the connecting groove 331, and the insertion rod 32 cannot be pulled out. Both first jacking components 23 are electrically connected to an external control terminal via signal transmitters. Operators control the telescopic ends of the two first jacking components 23 to push upwards, allowing them to abut against the interior of the mine roof, providing support. Under the interaction of these support forces, the position of the mounting column 21 is fixed. The height of the two arc-shaped support components 27 is adjustable, suitable for mines of different heights. When disassembly is no longer needed, the telescopic ends of the two first jacking components 23 are controlled to return to their initial positions. Next, the insertion rod 32 is pulled out: pulling the handle 38 causes the pull rod 37 to move, fully pulling the displacement block 35 into the assembly slot 34. Then, the operator can pull out the insertion rod 32 to release the lock. This design eliminates concerns about corrosion and disassembly difficulties even in humid environments, making installation and disassembly highly efficient and convenient, effectively improving worker productivity.

[0058] like Figure 1 , Figure 6As shown, the arc-shaped support component 27 in this embodiment includes: a vertical column 271 and an inclined column 272, and an arc-shaped plate 273. Both the vertical column 271 and the inclined column 272 are fixedly installed on the upper side of the fixing block 31, and the arc-shaped plate 273 is fixedly installed on the upper ends of both the vertical column 271 and the inclined column 272. In use, after the fixing block 31 is fixed, the two arc-shaped plates 273 are joined together to form a complete arc. Workers can use the two first jacking components 23 to push the two arc-shaped plates 273 up and down, thereby providing mine support. The arc-shaped support structure formed by the arc-shaped support components 27 on both sides, through the cooperation of the arc-shaped plate 273 with the vertical column 271 and the inclined column 272, and through stable transmission, enhances the overall structural strength and stability.

[0059] like Figure 1 , Figure 2 As shown, in this embodiment, sidewall protection mechanisms 4 are installed on the two mounting columns 21 on opposite sides. The sidewall protection mechanism 4 includes a second pushing member 42, a telescopic member, and a push plate 45. The second pushing member 42 can be a cylinder or a hydraulic cylinder. The telescopic member extends and retracts by the pushing of the second pushing member 42, thereby pushing the push plate 45 to move left and right. Specifically, the telescopic member uses a telescopic hinge frame 41, which has a first side and a second side. The first side faces the mounting column 21, and the second side connects to the push plate 45. The second jacking member 42 is fixedly installed on one side of the mounting column 21. A connecting block 44 is fixedly installed on the telescopic end of the second jacking member 42. The upper part of the telescopic hinge frame 41 near the mounting column 21 is hinged to the connecting block 44. The lower part of the telescopic hinge frame 41 near the mounting column 21 is hinged to the upper side of the base 1. A push plate 45 is hinged to the lower part of the telescopic hinge frame 41 away from the mounting column 21. Displacement grooves 46 are opened on both the front and rear parts of the push plate 45 near the mounting column 21. Moving blocks 47 are slidably installed inside the two displacement grooves 46. The upper part of the telescopic hinge frame 41 away from the mounting column 21 is hinged to the two moving blocks 47.

[0060] like Figure 1 , Figure 2 As shown, in use, the sidewall protection mechanism 4 can support the sidewall of the mine. When support of the mine sidewall is required, after the workers fix the mounting column 21, the two second jacking components 42 on the left and right sides are electrically connected to the external control terminal through signal transmitters. The workers start the two second jacking components 42, and the telescopic ends of the second jacking components 42 move down, pushing one end of the telescopic hinge frame 41 down. The telescopic hinge frame 41 extends, and then pushes the two push plates 45 on the left and right sides away from each other until the two push plates 45 abut against the mine sidewall, improving the support effect and preventing the mine sidewall from collapsing. This achieves more comprehensive support, not only supporting the top of the mine, but also supporting the mine sidewall, reducing the risk of collapse and improving safety.

[0061] The device is used as follows:

[0062] During installation, first place and fix the two bases 1 in their positions, then insert the slider 26 into the groove 25 on the assembly block 24, aligning the transverse hole 29 with the through hole 28. Insert the limiting rod 291 to fix the slider 26. Insert the insertion rod 32 of the right fixing block 31 into the insertion hole 33 of the left fixing block 31. Use the displacement block 35 and spring 36 to complete the splicing of the two fixing blocks 31, thereby fixing the arc-shaped support assembly 27. Send a signal through the external control terminal to control the telescopic ends of the two first jacking members 23 to push upward, so that the arc-shaped support assembly 27 abuts against the top of the mine, and use the supporting force to fix the mounting column 21. If it is necessary to support the mine sidewall, after fixing the mounting column 21, start the second jacking member 42 through the external control terminal. Its telescopic end moves downward to push the telescopic hinge frame 41 to extend, causing the push plate 45 to abut against the mine sidewall. During disassembly, the first pusher 23 is retracted, the handle 38 is pulled to retract the displacement block 35, the insert rod 32 is pulled out, and the limit rod 291 is removed to separate the components and complete the disassembly.

[0063] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
