Abstract
Description
Technical Field
[0001] This utility model relates to the field of scraper conveyor maintenance, and in particular to a positioning fixture for scraper conveyor maintenance. Background Technology
[0002] The scraper conveyor maintenance positioning fixture is a special auxiliary device used for the maintenance of heavy conveying equipment in coal mines and other mines. Through precise positioning and protective design, it ensures the safety of maintenance operations. In modern mining operations, the stable operation of scraper conveyors directly affects production efficiency, and the protection of components during the maintenance process is a key link to ensure the quality of equipment repair.
[0003] However, existing maintenance positioning fixtures have obvious safety protection defects. Traditional fixtures adopt a rigid fixed structure. When repairing precision parts, if they fall accidentally, the parts will directly bear the impact load, resulting in damage to the contact surface or internal structure. This hard collision not only increases maintenance costs but also creates secondary maintenance needs and prolongs equipment downtime. Based on this, a scraper conveyor maintenance positioning fixture is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a maintenance positioning fixture for scraper conveyors, which solves the problem of hard contact damage to precision components, soaring maintenance costs, and exacerbated production delays caused by the lack of a buffer protection mechanism when maintenance parts are accidentally dropped.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a scraper conveyor maintenance positioning fixture, including a base; and a sliding frame, the sliding frame being fixedly connected to the front end of the base, a limit rod being fixedly installed inside the sliding frame, sliders being slidably connected to the left and right sides of the outer surface of the limit rod, an installation platform being fixedly installed at the upper end of the slider, a damper being fixedly installed at the upper end of the installation platform, a spring being fixedly installed at the upper end of the installation platform, a receiving plate being fixedly installed at the upper end of the spring, the upper end of the damper being fixedly connected to the lower end of the receiving plate, and a clamping assembly, a quick-release assembly, and a lifting assembly being provided at the upper end of the base.
[0006] By setting a slider, the slider is pushed to move along the limit rod, which drives the two installation platforms to adjust the distance synchronously, accurately adapting to the size of the repair parts. The spring and damper work together. When the repair parts are accidentally dropped, the receiving plate absorbs the impact, the spring absorbs kinetic energy through elastic deformation, and the damper suppresses rebound oscillation. This achieves the purpose of adapting to repair parts of different sizes and providing drop protection. This solves the problem that the existing scraper conveyor maintenance positioning tooling lacks a buffer protection mechanism when repair parts are accidentally dropped, resulting in hard contact damage to precision parts, soaring maintenance costs, and increased production delays.
[0007] Furthermore, the clamping assembly includes a rotating handle, a mounting groove is provided at the upper end of the base, the rotating handle is rotatably connected to the left end of the base, and a transmission component is provided inside the mounting groove.
[0008] Furthermore, the transmission component includes a bidirectional lead screw, the two ends of which are rotatably connected to the inner wall of the mounting groove, and the handle is fixedly connected to the bidirectional lead screw. The handle is used to drive the bidirectional lead screw to rotate, and the outer surface of the bidirectional lead screw is provided with left and right symmetrical sliding parts.
[0009] Furthermore, the sliding component includes two slide blocks, which are threadedly connected to the outer surface of the bidirectional lead screw. When the bidirectional lead screw rotates, it drives the two slide blocks to move closer or further apart. A clamping plate is provided at the upper end of the slide block.
[0010] Furthermore, the quick-release assembly includes a base plate, two base plates are fixedly connected to the upper end of their corresponding slides, a guide rail is fixedly installed on the upper end of the base plate, a sliding platform is slidably connected to the outer surface of the guide rail, and a fixing component is provided on both the sliding platform and the upper end of the base plate.
[0011] Furthermore, the fasteners include pins, and slots are provided at the four upper corners of the sliding platform and the base plate. The eight pins are slidably connected to the interior of their corresponding slots.
[0012] Furthermore, the lifting assembly includes slide rods, four slide rods are fixedly connected to the upper end of their corresponding sliding platforms, two clamping plates are slidably connected to their corresponding slide rods, and two hydraulic rods symmetrically mounted on the upper end of each sliding platform. A connecting block is fixedly mounted on the output end of the hydraulic rod. The hydraulic rod is used to drive the connecting block to move. The connecting block is fixedly connected to the clamping plate. When the connecting block moves, it drives the clamping plate to slide on the slide rod.
[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0014] 1. The slider on the moving limit rod drives the two mounting platforms to adjust the distance synchronously to adapt to the size of the repair parts. When the repair parts are accidentally dropped, the receiving plate absorbs the impact, the spring absorbs the kinetic energy, and the damper suppresses the rebound oscillation. This design significantly improves the ease of operation and safety, and can easily adapt to repair parts of different sizes. The synergistic effect of the spring and the damper provides the receiving plate with effective dynamic buffering capacity, effectively suppressing the risk of secondary damage to the repair parts and damage to the equipment.
[0015] 2. A guide rail is provided so that the sliding platform with grooves and its connecting parts can be inserted into the guide rail and connected to the slide block. Slots and pins are provided so that when the sliding platform is inserted into the position, its slot is aligned with the slot on the base plate, and the pin is inserted to lock the position. This design significantly improves the efficiency of equipment disassembly and assembly and the convenience of maintenance. This boltless locking mechanism makes the installation and disassembly of the sliding platform and its accessories extremely simple and quick, greatly saving maintenance time and labor costs, and is especially suitable for scenarios that require frequent disassembly and assembly.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-5This utility model provides an embodiment of a scraper conveyor maintenance positioning fixture, including a base 1; it also includes a sliding frame 2, which is fixedly connected to the front end of the base 1. A limit rod 3 is fixedly installed inside the sliding frame 2. Slider 4s are slidably connected to the left and right sides of the outer surface of the limit rod 3. An installation platform 5 is fixedly installed at the upper end of the slider 4. A damper 6 is fixedly installed at the upper end of the installation platform 5. A spring 7 is fixedly installed at the upper end of the installation platform 5. A receiving plate 8 is fixedly installed at the upper end of the spring 7. The upper end of the damper 6 is fixedly connected to the lower end of the receiving plate 8. A clamping assembly, a quick-release assembly, and a lifting assembly are provided at the upper end of the base 1.
[0024] In this embodiment, by setting a slider 4, the slider 4 is pushed to move along the limiting rod 3, which drives the two mounting platforms 5 to adjust the distance synchronously to accurately fit the size of the repair parts. The spring 7 and the damper 6 work together so that when the repair parts are accidentally dropped, the receiving plate 8 absorbs the impact, the spring 7 absorbs the kinetic energy through elastic deformation, and the damper 6 suppresses the rebound oscillation, thereby achieving the purpose of adapting to repair parts of different sizes and providing drop protection.
[0025] Please see Figure 3 , Figure 5 In this embodiment, the clamping assembly includes a rotating handle 10. A mounting groove 9 is provided at the upper end of the base 1. The rotating handle 10 is rotatably connected to the left end of the base 1. A transmission component is provided inside the mounting groove 9, including a bidirectional lead screw 11. Both ends of the bidirectional lead screw 11 are rotatably connected to the inner wall of the mounting groove 9. The rotating handle 10 is fixedly connected to the bidirectional lead screw 11. The rotating handle 10 is used to drive the bidirectional lead screw 11 to rotate. Symmetrical sliding members are provided on the outer surface of the bidirectional lead screw 11. Each sliding member includes a slide block 12. The two slide blocks 12 are connected to the bidirectional lead screw 11... The outer surfaces of the two slides 11 are connected by threads. When the double-acting screw 11 rotates, it drives the two slides 12 to move closer or further apart. The upper end of the slide 12 is provided with a clamping plate 19. By setting a rotating handle 10, rotating the rotating handle 10 drives the double-acting screw 11 to rotate. When the double-acting screw 11 rotates, the rotation of the two slides 12 is restricted by the mounting groove 9, thereby driving the two slides 12 and their connected parts to move relative to each other. This controls the two clamping plates 19 to move closer together to clamp and fix the maintenance parts of the scraper conveyor, thereby achieving the purpose of fixing and positioning the maintenance parts.
[0026] Please see Figure 4 , Figure 5In this embodiment, the quick-release assembly includes a base plate 13. Two base plates 13 are fixedly connected to the upper ends of their corresponding slide blocks 12. A guide rail 14 is fixedly installed on the upper end of the base plate 13. A sliding platform 15 is slidably connected to the outer surface of the guide rail 14. Fixing components are provided on the upper ends of the sliding platform 15 and the base plate 13. The fixing components include pins 17. Slots 16 are provided at the four corners of the upper ends of the sliding platform 15 and the base plate 13. Eight pins 17 are slidably connected to the interior of their corresponding slots 16. By setting the guide rail 14, the sliding platform 15 can be inserted into it through its own groove, quickly completing the connection between the sliding platform 15 and its connected parts and the slide block 12. Then, by setting the slots 16 and pins 17, when the sliding platform 15 is inserted, its slots 16 will be aligned with the slots 16 on the base plate 13. At this time, the pins 17 are inserted into the slots 16 to fix the position of the sliding platform 15, thereby achieving the purpose of boltless installation and quick maintenance.
[0027] In this embodiment, the lifting assembly includes slide rods 18, four slide rods 18 are fixedly connected to the upper end of their corresponding sliding platforms 15, two clamping plates 19 are slidably connected to their corresponding slide rods 18, and two hydraulic rods 20 are fixedly installed symmetrically at the upper end of each of the two sliding platforms 15. A connecting block 21 is fixedly installed at the output end of the hydraulic rod 20. The hydraulic rod 20 is used to drive the connecting block 21 to move. The connecting block 21 is fixedly connected to the clamping plate 19. When the connecting block 21 moves, it drives the clamping plate 19 to slide on the slide rods 18.
[0028] It should be noted that by setting up the hydraulic rod 20, the hydraulic rod 20 drives the connecting block 21 to move when it runs. When the connecting block 21 moves, it drives the clamping plate 19 to move. Then, by setting up the slide rod 18, the clamping plate 19 is restricted so that the lower end of the clamping plate 19 will not shift when it is clamped. This achieves the purpose of adjusting the height of the repair part so that the staff can check the bottom of it.
[0029] The working principle of the above embodiments is as follows:
[0030] The operator turns the handle 10 to drive the double-acting screw 11 to rotate, forcing the two slide blocks 12 threadedly connected to the double-acting screw 11 to move towards each other under the restriction of the mounting groove 9 of the base 1. This causes the base plate 13 fixed on the slide block 12 and its connected slide rod 18 to move synchronously, so that the clamping plate 19 on the slide rod 18 clamps the repair part. Then, the hydraulic rod 20 is activated to push the connecting block 21, causing the clamping plate 19 to rise and fall along the slide rod 18 to adjust the height of the repair part. For repair parts of different sizes, the slider 4 is pushed to slide along the limit rod 3, which can simultaneously adjust the distance between the two mounting platforms 5. If the repair part falls accidentally, the receiving plate 8 will absorb the impact, triggering the spring 7 to deform and absorb the kinetic energy. At the same time, the damper 6 will suppress the rebound vibration. When quick disassembly and assembly are required, the sliding platform 15 is inserted into the base plate 13 through the guide rail 14, aligned and the pin 17 is inserted into the slot 16 to lock, achieving boltless fixation.
[0031] It should be noted that the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.
