Description

Technical Field

[0001] This utility model relates to the field of waste collection technology, and more specifically, it relates to a device for preventing the explosion wall from falling. Background Technology

[0002] While existing explosion venting wall fall arrestors offer some functionality in terms of protection and pressure relief, they still have some significant shortcomings in practical applications. One prominent issue is the difficulty in adjusting the location of the waste collection box, as well as the inconvenience of installation and disassembly.

[0003] Existing waste collection bins often use a fixed installation structure, which cannot flexibly adjust their installation position according to the site space layout, operation requirements, or waste accumulation. This fixed design limits the adaptability of the device, especially in complex or confined construction environments, which may lead to the inability to collect waste in a timely and effective manner, affecting the normal operation of the equipment and cleaning efficiency.

[0004] Currently, waste bins are typically connected to the main structure via bolts or welding. Installation and disassembly require specialized tools, involve numerous steps, and are time-consuming. This not only increases maintenance workload but also hinders the quick replacement or cleaning of waste bins, thus reducing overall work efficiency.

[0005] In actual use, the waste bin is difficult to disassemble, and maintenance personnel may need to perform high-intensity physical operations during cleaning or replacement, which increases safety hazards. At the same time, frequent disassembly and assembly may also cause wear and loosening of the connecting parts, thereby affecting the long-term stability and service life of the device.

[0031] Please see Figures 1-5 A fall-prevention device for an explosion-proof wall includes a main frame 1, a housing adjustment mechanism, a housing locking mechanism, and a locking auxiliary mechanism. The housing adjustment mechanism includes an adjustment frame 2, a drive motor 3, a rotating shaft 4, a transmission belt assembly 5, a driving block 6, a moving block 7, and a collection box 8. The adjustment frame 2 is vertically and movably fixedly mounted on the front end face of the main frame 1. The drive motor 3 is mounted on the adjustment frame 2. The rotating shaft 4 is mounted on the output end of the drive motor 3 and is connected to the transmission belt assembly 5. The driving block 6 is mounted on the transmission belt assembly 5, and the moving block 7 is connected to the driving block 6. The collection box 8 is configured to cooperate with the moving block 7. The box body locking mechanism includes a locking tube 9, a locking rod 10, an inclined rail 11, an inclined sliding block 12, an insert 13, an insert groove 14, inner and outer frames 15, and a slope pusher 16. The inclined rail 11 is set on the inner wall of the locking tube 9. The inclined sliding block 12 is inclinedly slidably installed on the inclined rail 11. The insert 13 is installed on the side of the inclined sliding block 12. The insert groove 14 is set on the side wall of the locking rod 10. The inner and outer frames 15 are longitudinally slidably installed on the inner and outer walls of the locking tube 9. The slope pusher 16 is longitudinally slidably installed on the outer wall of the locking tube 9.

[0032] In this embodiment, the adjustment frame 2, responsible for the position adjustment and stable support of the collection box 8, firstly adjusts and fixes itself on the front end of the main frame 1 according to the wall height and working requirements, providing an initial working platform for the entire mechanism. After the drive motor 3 installed on the adjustment frame 2 starts, it drives the transmission belt assembly 5 through the output shaft 4. The drive block 6 on the transmission belt assembly 5 moves accordingly, and drives the moving block 7 connected to it to slide smoothly along the guide rail 29 at the top of the adjustment frame 2. The moving block 7 is connected to the collection box 8, thereby realizing the horizontal position adjustment of the collection box 8, ensuring the stability and accuracy of the collection box 8 during the adjustment process. The position of the collection box 8 can be accurately located according to the expected landing point of the explosive material. The motor speed control drives the movement speed of block 6, thereby controlling the movement speed and positioning accuracy of collection box 8. When collection box 8 needs to be installed, first align the snap-fit ​​rod 10 fixed on the moving block 7 with the snap-fit ​​tube 9 on the connecting plate 30 on the bottom surface of the inside of collection box 8. After the snap-fit ​​rod 10 is inserted into the snap-fit ​​tube 9, the inner and outer frames 15 push the inclined block 12 to move. The inclined rail 11 on the inner wall of the snap-fit ​​tube 9 guides the inclined block 12 to tilt and slide. During the movement, the insert 13 on the side of the inclined block 12 aligns with and inserts into the groove 14 on the side wall of the snap-fit ​​rod 10, forming a preliminary lock. This ensures accurate alignment and firm connection during the snap-fit ​​process, significantly improving the reliability of the connection between collection box 8 and moving block 7, and maintaining stability even under explosion impact.

[0033] The locking auxiliary mechanism includes a drive ring 17, a misalignment plate 18, a pivot support block 19, an outer fixing ring 20, a tightening block 21, and a tightening spring 22. The drive ring 17 is rotatably mounted on the outer wall of the locking tube 9. The pivot support block 19 is mounted on the bottom end of the drive ring 17. The outer fixing ring 20 is fixedly mounted on the bottom end of the outer wall of the locking tube 9. Multiple sets of tightening blocks 21 are slidably mounted on the outer wall of the locking tube 9. The tightening spring 22 is mounted between adjacent tightening blocks 21. The pivot support block 19 passes through the spaces between the tightening blocks 21 in sequence, so that the drive ring 17 rotates stably. The misalignment plate 18 is mounted on the top end of the drive ring 17. The rotation of the misalignment plate 18 pushes the ramp pusher 16 to move, so that the ramp pusher 16 pushes the inner and outer frames 15 to move longitudinally.

[0034] In this embodiment, a convenient operation method and locking force control are provided for the locking of the housing. When the locking rod 10 is inserted into the locking tube 9, the operator rotates the upper limit rotating drive ring 17 installed on the outer wall of the locking tube 9. The rotating support block 19 at the bottom of the drive ring 17 passes through the tightening blocks 21 that are slidably installed on the outer wall of the locking tube 9 in sequence, compressing the tightening spring 22 between adjacent tightening blocks 21, generating appropriate feedback force and damping. At the same time, the misalignment plate 18 installed on the top of the drive ring 17 rotates accordingly, pushing the slope pusher 16 on the outer wall of the locking tube 9 to move longitudinally. The slope pusher 16 then pushes the inner and outer frames 15 to move longitudinally, enhancing the locking force between the locking rod 10 and the locking tube 9. The return spring 32 installed between the support plate 31 on the side wall of the locking tube 9 and the inner and outer frames 15 ensures that the system can return to the initial state after the lock is released. The fixed installation of the outer fixing ring 20 provides a stable working foundation for the tightening block 21, making the entire auxiliary mechanism operate smoothly and reliably.

[0035] Please see Figures 1-5 As a supplementary embodiment of the explosion-proof wall anti-fall device for the box adjustment mechanism, box locking mechanism and locking auxiliary mechanism: An extension rod 23 is installed at the bottom end of the main frame 1. A rotating rod 24 is rotatably installed at one end of the extension rod 23. A hydraulic cylinder 25 is rotatably installed between the rotating rod 24 and the extension rod 23. A bonding plate 26 is installed at one end of the rotating rod 24. A bolt hole 27 is opened on the bonding plate 26. The bonding plate 26 is in contact with the wall surface for support. A counterweight block 28 is installed at the bottom end of the main frame 1. The top end of the adjusting frame 2 is equipped with a guide rail 29, and the moving block 7 is slidably guided on the guide rail 29. The bottom end of the side wall of the clamping pipe 9 is equipped with a connecting plate 30, and the connecting plate 30 is fixedly installed on the inner bottom surface of the collection box 8. The side wall of the clamping pipe 9 is fixedly installed with a support plate 31, and a return spring 32 is installed between the support plate 31 and the inner and outer frames 15. The clamping rod 10 is fixedly installed on the moving block 7, and the clamping pipe 9 on the collection box 8 can fit the clamping rod 10 into the clamping pipe 9.

[0036] More specifically, the main frame 1 is transported to the vicinity of the explosion relief wall, and the support structure is deployed through the extension rod 23 and rotating rod 24 at the bottom. The fitting plate 26 at one end of the rotating rod 24 is fixedly connected to the wall through the bolt hole 27. The angle between the rotating rod 24 and the extension rod 23 is adjusted by the hydraulic cylinder 25 to maintain an appropriate distance and angle between the main frame 1 and the explosion relief wall. The counterweight block 28 at the bottom of the main frame 1 provides the necessary balancing weight to enhance the overall stability. The installation position of the adjusting frame 2 on the front end of the main frame 1 is adjusted and fixed according to the height of the explosion relief wall. The clamping pipe 9 on the connecting plate 30 at the bottom of the collection box 8 is aligned with the clamping rod 10 on the moving block 7. After initial alignment, the drive motor 3 is started, and the moving block 7 is precisely positioned along the guide rail 29 to the expected landing point of the explosive material via the transmission belt assembly 5. After the collection box 8 is aligned, the locking rod 10 is inserted into the locking tube 9, and the operating ring 17 is rotated clockwise to drive the locking auxiliary mechanism, so that the insert 13 of the inclined block 12 enters the groove 14 of the locking rod 10. At the same time, the inner and outer frames 15 lock the locking rod 10, realizing a firm connection between the collection box 8 and the moving block 7. The fragments and waste generated by the explosion relief wall will fall into the precisely positioned collection box 8, effectively preventing fragments from flying everywhere and causing secondary damage. The collection box 8 can be adjusted according to the pattern of fragment landing.

[0037] In summary, during the use or operation of the overall equipment: when the box adjustment mechanism is required to operate, it is responsible for adjusting the position and providing stable support for the collection box 8. First, the adjustment frame 2 can be adjusted and fixed on the front face of the main frame 1 according to the wall height and work requirements, providing an initial working platform for the entire mechanism. After the drive motor 3 installed on the adjustment frame 2 starts, it drives the transmission belt assembly 5 through the output shaft 4. The drive block 6 on the transmission belt assembly 5 moves accordingly, and drives the moving block 7 connected to it to slide smoothly along the guide rail 29 on the top of the adjustment frame 2. The moving block 7 is connected to the collection box 8, thereby realizing the horizontal position adjustment of the collection box 8, ensuring the stability and accuracy of the collection box 8 during the adjustment process. The position of the collection box 8 can be accurately located according to the expected landing point of the explosive material. Throughout the process, the motor speed controls the movement speed of the drive block 6, thereby controlling the movement speed and positioning accuracy of the collection box 8.

[0038] When the box-locking mechanism is in operation, it is responsible for the connection and fixation between the collection box 8 and the moving block 7. When the collection box 8 needs to be installed, first align the locking rod 10 fixed on the moving block 7 with the locking tube 9 on the connecting plate 30 on the bottom surface of the collection box 8. After the locking rod 10 is inserted into the locking tube 9, the inner and outer frames 15 push the inclined block 12 to move. The inclined rail 11 on the inner wall of the locking tube 9 guides the inclined block 12 to tilt and slide. During the movement, the insert 13 on the side of the inclined block 12 aligns with and inserts into the groove 14 on the side wall of the locking rod 10 to form a preliminary lock, ensuring accurate alignment and firm connection during the locking process. This significantly improves the reliability of the connection between the collection box 8 and the moving block 7, and can remain stable even under the impact of explosion.

[0039] When the locking auxiliary mechanism is in operation, it provides a convenient operation method and locking force control for the housing locking. After the locking rod 10 is inserted into the locking tube 9, the operator rotates the upper limit rotating drive ring 17 installed on the outer wall of the locking tube 9. The rotating support block 19 at the bottom of the drive ring 17 passes through the tightening block 21 installed in a concentric manner on the outer wall of the locking tube 9, compressing the tightening spring 22 between adjacent tightening blocks 21, generating appropriate feedback force and damping. At the same time, the misalignment plate 18 installed at the top of the drive ring 17 rotates accordingly, pushing the slope pusher 16 on the outer wall of the locking tube 9 to move longitudinally. The slope pusher 16 then pushes the inner and outer frames 15 to move longitudinally, enhancing the locking force between the locking rod 10 and the locking tube 9. The return spring 32 installed between the support plate 31 on the side wall of the locking tube 9 and the inner and outer frames 15 ensures that the system can return to the initial state after the lock is released. The fixed installation of the outer fixing ring 20 provides a stable working foundation for the tightening block 21, making the entire auxiliary mechanism operate smoothly and reliably.

[0040] The main frame 1 is transported to the vicinity of the explosion relief wall. The support structure is deployed via the extension rod 23 and rotating rod 24 at the bottom. The fitting plate 26 at one end of the rotating rod 24 is fixedly connected to the wall surface through the bolt hole 27. The angle between the rotating rod 24 and the extension rod 23 is adjusted using the hydraulic cylinder 25 to maintain an appropriate distance and angle between the main frame 1 and the explosion relief wall. The counterweight block 28 at the bottom of the main frame 1 provides the necessary balancing weight to enhance overall stability. The installation position of the adjusting frame 2 on the front face of the main frame 1 is adjusted and fixed according to the height of the explosion relief wall. The locking pipe 9 on the connecting plate 30 at the bottom of the collection box 8 is aligned with the locking rod 10 on the moving block 7 to achieve initial... First, align the device and start the drive motor 3. The drive belt assembly 5 drives the moving block 7 to be precisely positioned along the guide rail 29 to the expected landing point of the explosive material. After the collection box 8 is aligned, insert the locking rod 10 into the locking tube 9. Operate the drive ring 17 to rotate clockwise, driving the locking auxiliary mechanism so that the insert 13 of the inclined block 12 enters the groove 14 of the locking rod 10. At the same time, the inner and outer frames 15 lock the locking rod 10, realizing a firm connection between the collection box 8 and the moving block 7. The fragments and waste generated by the explosion relief wall will fall into the precisely positioned collection box 8, effectively preventing fragments from flying everywhere and causing secondary damage. The collection box 8 can be adjusted according to the pattern of fragment landing.

For all the fixed connections mentioned above, welding is preferred.
