Description

Technical Field

[0001] This application relates to the field of mine restoration technology, and in particular to a slope support structure for mine restoration. Background Technology

[0002] The published patent with authorization announcement number CN218263932U discloses a slope support structure for mine restoration, including a support frame and a protective net. Push plates are installed inside both sides of the support frame, and a second spring is fixedly connected between the push plates and the support frame. A push rod is fixedly connected to one side of the push plate. Through a locking mechanism and a pressing mechanism, the push rod can be pushed out of the slot by pressing the push plate inward. At this time, the protective net can be separated from the support frame by pulling the pull block outward, thus enabling the disassembly of the protective net. When the protective net is aligned with the support frame, the lock plate can be engaged with the slot by pressing the protective net inward, thereby achieving the installation and fixation of the protective net and facilitating its replacement. This improves the slope protection strength, further enhances the stability of the soil and rock, and improves the practicality of the slope support structure for mine restoration.

[0003] The slope support structure for mine restoration in the aforementioned patent can replace the protective netting, but it requires the old protective netting to be removed before the new one is installed. This process is cumbersome, time-consuming, labor-intensive, increases labor intensity, and reduces replacement efficiency.

[0004] Therefore, this application proposes a slope support structure for mine restoration. Utility Model Content

[0005] This application proposes a slope support structure for mine restoration to solve the problems mentioned in the background art. By setting up a replacement mechanism, turning the handwheel drives the take-up roller to rotate synchronously. When the take-up roller rotates, the old protective netting is wound onto the take-up roller, while at the same time, the new protective netting on the unwind roller is unwound, allowing the new protective netting to unfold and replace the old one. This eliminates the need to remove the old protective netting first and then install the new one, achieving rapid replacement, improving replacement efficiency, and making the operation simple and convenient. It does not require excessive time and effort, reduces the labor force of workers, and greatly enhances the practicality of the device.

[0006] To achieve the above objectives, this application adopts the following technical solution: A slope support structure for mine restoration includes a fixed frame, a mounting frame, a protective net, a replacement mechanism, a fixing mechanism, and a pressing mechanism. The mounting frame is fixedly connected to the top of the fixed frame. The protective net is installed inside the mounting frame. The replacement mechanism and the fixing mechanism are installed inside the mounting frame. The protective net is connected to the replacement mechanism, and the fixing mechanism abuts against the replacement mechanism.

[0007] In a preferred embodiment, the replacement mechanism includes a drive pulley, a driven pulley, a handwheel, an unwinding roller, and a winding roller. The unwinding roller and the winding roller are rotatably connected inside the mounting frame, and the two ends of the protective net are respectively connected to the unwinding roller and the winding roller. As the take-up roller rotates, the old protective netting is wound onto it. At the same time, the new protective netting is unwound from the unwind roller, allowing the new netting to unfold and replace the old one. This eliminates the need to remove the old netting before installing the new one, enabling rapid replacement, improving efficiency, and enhancing the practicality of the device.

[0008] In a preferred embodiment, a drive pulley and a driven pulley are fixedly connected to the unwinding roller and the winding roller, respectively, and the drive pulley and the driven pulley are connected by belt drive. By turning the handwheel, the take-up roller rotates synchronously. When the drive pulley on the take-up roller rotates, it drives the driven pulley through the belt to make the unwind roller rotate, thereby improving the practicality of the device.

[0009] In a preferred embodiment, one end of the take-up roller extends outside the mounting frame and is fixedly connected to a handwheel; A handwheel is connected to one end of the winding roller. By simply controlling the handwheel to rotate, the old protective netting can be wound up by rotating the winding roller, thus improving the practicality of the device.

[0010] In a preferred embodiment, the fixing mechanism includes a driving gear, a driven gear, a spring, a movable plate, and a locking tooth. The driving gear is fixedly connected to the take-up roller, and the driven gear is rotatably connected inside the mounting frame. The driving gear and the driven gear are meshed together. By setting up a driving gear and a driven gear, and utilizing the self-locking property between the driving gear and the driven gear, the self-rotation of the winding roller can be prevented, thereby improving the practicality of the device.

[0011] In a preferred embodiment, the spring is disposed inside the mounting bracket, one end of the spring is fixedly connected to a movable plate, and a retaining tooth is fixedly connected to the side of the movable plate away from the spring, and the retaining tooth meshes with the driven gear. By releasing the movable plate, the spring causes the locking teeth to mesh with the driven gear. The spring provides elastic force to ensure a tight fit between the locking teeth and the driven gear, improving the stability and reliability of the positioning. This prevents the handwheel from rotating during use and affecting the stability of the protective net, thus enhancing the practicality of the device.

[0012] In a preferred embodiment, the pressing mechanism includes a pressure bar, a fixing block, and a rotating rod. Both fixing blocks are fixedly connected to the fixing frame, and the rotating rod is threadedly connected to the inside of both fixing blocks. The two rotating rods are rotatably connected to the pressure bar, and the bottom of the two pressure bars contacts the top of the mounting frame. By setting up a pressing mechanism and rotating the rotating rod, the pressure strip is moved down, so that the pressure strip is pressed and fixed on both sides of the protective net, so as to prevent the protective net from lifting up on both sides during use and affecting the protective effect, thereby improving the practicality of the device.

[0013] The beneficial effects of this application are: 1. This slope support structure for mine restoration features a replacement mechanism. By turning the handwheel, the take-up roller rotates synchronously. When the take-up roller rotates, the old protective netting is wound onto it, while the new protective netting on the unwind roller is unwound. This allows the new protective netting to unfold and replace the old one, eliminating the need to remove the old netting before installing the new one. This enables rapid replacement, improves efficiency, and is simple and convenient to operate. It does not require excessive time or effort, reduces labor costs, and greatly enhances the practicality of the device. 2. This slope support structure for mine restoration is equipped with a pressing mechanism. By rotating the rotating rod, the pressure strip is moved downward, so that the pressure strip is pressed and fixed on both sides of the protective net. This prevents the protective net from tilting up on both sides during use and affecting the protective effect, thus greatly improving the practicality of the device. Attached Figure Description

[0016] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0017] Reference Figure 1-4 A slope support structure for mine restoration includes a fixed frame 1, an installation frame 2, a protective net 3, a replacement mechanism 4, a fixing mechanism 5, and a pressing mechanism 6. The top of the fixed frame 1 is fixedly connected to the installation frame 2. The installation frame 2 is equipped with a protective net 3 inside. The installation frame 2 is equipped with a replacement mechanism 4 and a fixing mechanism 5 inside. The protective net 3 is connected to the replacement mechanism 4, and the fixing mechanism 5 abuts against the replacement mechanism 4.

[0018] Reference Figure 1-4 The replacement mechanism 4 includes a drive pulley 41, a driven pulley 42, a handwheel 43, an unwinding roller 44, and a take-up roller 45. The unwinding roller 44 and the take-up roller 45 are rotatably connected inside the mounting frame 2, and the two ends of the protective net 3 are respectively connected to the unwinding roller 44 and the take-up roller 45. When the take-up roller 45 rotates, the old protective net 3 will be wound around the take-up roller 45. At the same time, the new protective net 3 on the unwinding roller 44 will be unwound, so that the new protective net 3 unfolds to replace the old protective net 3. There is no need to remove the old protective net 3 first and then install the new protective net 3, which realizes quick replacement, improves replacement efficiency, and thus enhances the practicality of the device.

[0019] Reference Figure 1-3 The unwinding roller 44 and the winding roller 45 are respectively fixedly connected to a drive pulley 41 and a driven pulley 42, which are connected by belt drive. By turning the handwheel 43, the winding roller 45 is driven to rotate synchronously. When the drive pulley 41 on the winding roller 45 rotates, it drives the driven pulley 42 through the belt to cause the unwinding roller 44 to rotate, thereby improving the practicality of the device.

[0020] Reference Figure 1-3 One end of the take-up roller 45 extends to the outside of the mounting frame 2 and is fixedly connected to a handwheel 43. Since the handwheel 43 is connected to one end of the take-up roller 45, the old protective net 3 can be wound up by simply controlling the rotation of the handwheel 43, thereby improving the practicality of the device.

[0021] Reference Figure 1-3 The fixing mechanism 5 includes a drive gear 51, a driven gear 52, a spring 53, a movable plate 54, and a locking tooth 55. The drive gear 51 is fixedly connected to the take-up roller 45, and the driven gear 52 is rotatably connected inside the mounting frame 2. The drive gear 51 and the driven gear 52 are meshed together. By setting the drive gear 51 and the driven gear 52, the self-locking property between the drive gear 51 and the driven gear 52 can prevent the take-up roller 45 from rotating, thereby improving the practicality of the device.

[0022] Reference Figure 1-4Spring 53 is installed inside mounting bracket 2. One end of spring 53 is fixedly connected to movable plate 54. On the side of movable plate 54 away from spring 53, a retaining tooth 55 is fixedly connected, and retaining tooth 55 meshes with driven gear 52. By releasing movable plate 54, under the action of spring 53, retaining tooth 55 is driven to mesh with driven gear 52. Spring 53 provides elastic force to ensure tight fit between retaining tooth 55 and driven gear 52, improving the stability and reliability of positioning, and preventing handwheel 43 from rotating during use and affecting the stability of protective net 3, thereby improving the practicality of the device.

[0023] Reference Figure 1-4 The pressing mechanism 6 includes a pressure strip 61, a fixing block 62, and a rotating rod 63. The two fixing blocks 62 are fixedly connected to the fixing frame 1. The rotating rod 63 is threadedly connected to the inside of the two fixing blocks 62, and the two rotating rods 63 are rotatably connected to the pressure strip 61. The bottom of the two pressure strips 61 contacts the top of the mounting frame 2. By setting the pressing mechanism 6, rotating the rotating rod 63 drives the pressure strip 61 to move down, so that the pressure strip 61 presses down on both sides of the protective net 3 to prevent the protective net 3 from tilting up on both sides during use and affecting the protective effect, thereby improving the practicality of the device.

[0024] Working principle: The fixed frame 1 is fixed to the slope by the positioning anchor rod at the bottom and is protected by the protective net 3. When the protective net 3 needs to be replaced, one hand moves the movable plate 54 towards the spring 53, which drives the locking tooth 55 to move synchronously, and the driven gear 52 is in an active state. The other hand turns the handwheel 43, which drives the take-up roller 45 to rotate synchronously. When the take-up roller 45 rotates, it will wind the old protective net 3 onto the take-up roller 45. At the same time, the new protective net 3 will be unwound on the unwind roller 44, so that the new protective net 3 unfolds and replaces the old protective net 3. There is no need to remove the old protective net 3 first and then install the new one, which can achieve quick replacement and improve replacement efficiency. The operation is simple and convenient, requiring little time and effort, and reducing the labor load for workers. When the new protective net 3 completely replaces the old one, the movable plate 54 is released. Under the action of the spring 53, the locking teeth 55 engage with the driven gear 52. The spring 53 provides elastic force to ensure a tight fit between the locking teeth 55 and the driven gear 52, improving the stability and reliability of the positioning. This prevents the handwheel 43 from rotating during use and affecting the stability of the protective net 3. In addition, by setting the pressing mechanism 6, rotating the rotating rod 63 causes the pressure strip 61 to move downward, so that the pressure strip 61 presses against both sides of the protective net 3 for fixation, preventing the protective net 3 from tilting up on both sides during use and affecting the protective effect.

[0025] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and the inventive concept of this application, should be included within the scope of protection of this application.
