Abstract
Description
Technical Field
[0001] This invention relates to the field of elevator counterweight technology, and more particularly to an elevator counterweight with an anti-detachment mechanism. Background Technology
[0002] An elevator counterweight is a weight balancing device that balances the weight of the elevator car with the effective load portion to reduce energy consumption and motor power loss. It is mainly a counterweight device to prevent excessive motor movement.
[0003] The counterweight device of an elevator mainly includes a counterweight frame, counterweight blocks, sliding guide shoes, and a buffer head. The counterweight frame mainly restricts the position of the counterweight blocks, while the sliding guide shoes ensure the direction of movement of the entire counterweight device and are the main components connecting the counterweight device to the external sliding support structure. In the current use of elevator counterweight devices, due to the long-term sliding under load, when the weight deviates, the connection between the guide shoes and the external support structure will deviate, causing the guide shoes to deform or even break. This leads to the counterweight device slipping off the external support structure, affecting the balance of the counterweight device, causing the elevator to operate dangerously, and affecting the safety of elevator use.

[0034] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.
[0035] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0036] Example 1:
[0037] An elevator counterweight with an anti-detachment mechanism, such as Figure 1-9 As shown, it includes a counterweight support frame 1, a support guide shoe 2 fixedly installed on one side of the counterweight support frame 1, and a movable support chamber 11 opened on one side of the counterweight support frame 1.
[0038] There are at least four support guide shoes 2, and the four support guide shoes 2 are located at the four corners of the counterweight support frame 1. Several short sensing columns 3 are set above the support guide shoes 2. Long sensing columns 45 are set on both sides of the support guide shoes 2. The short sensing columns 3 are located between two long sensing columns 45. A connecting moving plate 31 is set above the support guide shoes 2. A connecting frame 30 is set between the support guide shoes 2 and the connecting moving plate 31.
[0039] A support connecting plate 4 and a support connecting block 5 are fixedly connected to one side of the counterweight support frame 1. The support connecting block 5 is inserted into the support connecting plate 4. Connecting columns 6 are fixedly connected to the upper ends of both the support connecting block 5 and the support connecting plate 4. A rotating connecting plate 7 is rotatably mounted above the two connecting columns 6. An arc-shaped moving plate 12 is fixedly mounted on one side of the rotating connecting plate 7. A moving block 19 is fixedly connected to the arc-shaped moving plate 12 by a pull rope 18. A snap-fit support ring 20 is inserted into the moving block 19. A rotating support base plate 21 is inserted into the snap-fit support ring 20. A support shell 28 is rotatably connected to the rotating support base plate 21. A blocking plate 22 is mounted above the support shell 28. A snap-fit plate 27 is mounted on one side of the blocking plate 22. The moving block 19 is inserted into the snap-fit plate 27, and the snap-fit plate 27 is inserted into the support shell 28. A support plate 23 is provided on the side of the blocking plate 22 away from the snap-fit plate 27. At least two telescopic springs 25 are fixedly connected to one side of the support plate 23. A rotating connecting plate 42 is fixedly connected to the upper end of the long sensing column 45. The rotating connecting plate 42 is fixedly connected to the connecting frame 30 through the connecting rope 41. The rotating connecting plate 42 is fixedly connected to the connecting rope 41. A sliding connecting rod 38 is fixedly connected to the end of the connecting frame 30 away from the connecting rope 41. The sliding connecting rod 38 is located above the moving block 19. The connecting moving plate 31 is rotatably set between the two snap-fit plates 27. A sliding support frame 46 is fixedly connected to the snap-fit support port 47. The snap-fit plate 27 is inserted into the snap-fit support port 47. There are several snap-fit support ports 47. The snap-fit support ports 47 are opened on one side of the sliding support frame 46.
[0040] When this device is in use, if the support guide shoes 2 at the four corners of the counterweight support frame 1 deform, they will collide with the short sensing columns 3 on the outside or the long sensing columns 45 on the upper and lower sides. After being impacted, the short sensing columns 3 will drive the support connecting plate 4 and the connecting column 6 to move towards the rotating connecting plate 7. This causes the rotating connecting plate 7 to move the pulling rope 18 simultaneously under the connection of the arc-shaped moving plate 12. This causes the moving block 19 to move downward inside the locking support ring 20, causing the locking support ring 20 to move outward from the locking plate 27, thus releasing the... In addition to the snapping effect between the rotating support base plate 21 and the snap-fit support ring 20, the rotating support base plate 21 moves downward under the rotational support of the snap-fit plate 27, causing the blocking plate 22 to fall into the support shell 28. Then, under the elastic action of the two telescopic springs 25, the snap-fit plate 27 moves towards the sliding support frame 46 under the support of the support plate 23, causing the snap-fit support opening 47 to snap and fix the snap-fit plate 27. Simultaneously, through the connecting moving plate 31, the connection effect of the two snap-fit plates 27 on both sides is achieved. When the snap-fit plate 27 touches the engagement... When the movable plate 31 is connected, the movable block 19 moves downward under the connection of the connecting frame 30 and the sliding connecting rod 38, releasing the blocking plate 22 to insert and fix the other side's snap-fit plate 27 to the snap-fit support port 47, achieving a multiple buffering effect. When the long sensing column 45 is subjected to impact, it will move outward towards the counterweight support frame 1, thereby driving the connecting frame 30 and the sliding connecting rod 38 towards the movable block 19 under the connection of the connecting rope 41, thus releasing the blocking plate 22 and fixing the snap-fit plate 27 to the snap-fit support port 47. The locking effect of the support port 47, through the connection effect of multiple short sensing columns 3 and long sensing columns 45 when the support guide shoe 2 deforms, allows the locking plate 27 to be locked and fixed to the locking support port 47. In addition, the moving support effect of the connecting moving plate 31 and the connecting frame 30 on the two sides of the locking plate 27 allows the locking plate 27 and the sliding support frame 46 to be locked multiple times. When the support guide shoe 2 is connected and tightened, the counterweight support frame 1 and the sliding support frame 46 can be reinforced in time, effectively preventing the counterweight device from falling off.
[0041] This device, through multiple short sensing columns 3 and long sensing columns 45 set on the outside of the support guide shoe 2, can promptly transmit the signal when the support guide shoe 2 deforms. Through the connection effect between the set rotating connecting plate 7, arc-shaped moving plate 12 and pulling rope 18, the blocking plate 22 can be released in time, so that the locking plate 27 and the locking support port 47 can be stably locked. By setting the moving block 19 as a gradually widening structure, the position of the locking support ring 20 can be moved by the downward movement of the moving block 19, so as to release the locking effect between the rotating support base plate 21 and the locking support ring 20, thereby ensuring that the locking plate 27 can move out of the support shell 28 in time and quickly. Through the transmission effect of the connecting moving plate 31 set between the two locking plates 27 on the two sides of the locking plates 27, the locking plate 27 on the other side can be extended and locked in time when the locking plate 27 breaks or deforms. Through the repeated action of multiple locking plates 27, the elevator counterweight can be buffered and locked multiple times, preventing the counterweight device from detaching from the connection with the sliding support frame 46.
[0042] like Figure 3 As shown, the rotating connecting plate 7 is fixedly connected to the rotating support rod 10 via the rotating support cylinder 9. The rotating connecting plate 7 is fixedly installed on the outside of the rotating support cylinder 9, and the rotating support rod 10 is rotatably installed inside the movable support chamber 11. A horizontal support block 8 is provided below the rotating connecting plate 7, and the horizontal support block 8 is fixedly connected to the support guide shoe 2.
[0043] Arc-shaped support chambers 14 are provided on the inner walls of the movable support chamber 11 on both sides. The arc-shaped movable plate 12 is slidably connected to the arc-shaped support chamber 14 through the limiting sliding rod 13. The arc-shaped movable plate 12 is fixedly connected to the limiting sliding rod 13. A rotating connecting belt 15 is fixedly connected to the side of the arc-shaped movable plate 12 away from the rotating connecting plate 7.
[0044] A support wheel 16 is provided below the arc-shaped movable plate 12. The support wheel 16 is connected to the rotating connecting belt 15 by belt drive. The support wheel 16 is rotatably connected to the movable support chamber 11 through the rotating column 17. The support wheel 16 is fixedly connected to the rotating column 17.
[0045] When the rotating connecting plate 7 moves upward under the support of the rotating support cylinder 9 and the rotating support rod 10, it will drive the arc-shaped moving plate 12 to rotate inside the arc-shaped support chamber 14 with the support wheel 16 as the center and the rotating connecting belt 15 as the radius. The support of the moving support chamber 11 on the rotating column 17 can ensure the stability and accuracy of the arc-shaped moving plate 12 when it rotates and drives the upper part to move, thereby ensuring the accuracy of the device in terms of running direction and distance.
[0046] This device, through the setting of the limiting sliding rod 13, achieves the effect of limiting the rotation distance of the arc-shaped moving plate 12 under the rotation support of the support wheel 16. Through the cooperation of the support wheel 16 and the arc-shaped support chamber 14, the accuracy of the position of the arc-shaped moving plate 12 when it rotates can be guaranteed, thereby ensuring the stability and reliability of the device when it is connected and moved.
[0047] like Figure 3 and Figure 4 As shown, a fixed housing 26 is fixedly connected to the side of the telescopic spring 25 away from the support plate 23. The telescopic spring 25 is located inside the fixed housing 26. A limit rod 24 is fixedly installed in the middle of the telescopic spring 25. The limit rod 24 is fixedly connected to the fixed housing 26. The fixed housing 26 is fixedly installed inside the support housing 28. A fixed housing 26 is fixedly installed above the blocking plate 22. The fixed housing 26 is fixedly connected to the support housing 28.
[0048] When the blocking plate 22 moves downward under the elastic support of the telescopic spring 25 inside the fixed housing 26, the support plate 23 moves under the elasticity of the two telescopic springs 25, so that one side device can be stably popped out of the support housing 28 to achieve the effect of engaging with the external device.
[0049] This device, through the setting of the internal limiting rod 24 of the telescopic spring 25, can ensure the stability of the position of the telescopic spring 25 when it is compressed inside the fixed housing 26, thereby ensuring the stability of the position of the telescopic spring 25 during continuous compression and ensuring the accuracy of the direction when it rebounds.
[0050] like Figure 5 , Figure 6 and Figure 7 As shown, a rotating support column 32 is fixedly connected to the upper end of the support guide shoe 2, and a connecting movable plate 31 is inserted into the upper end of the rotating support column 32. The rotating support column 32 is rotatably disposed inside the connecting movable plate 31.
[0051] A fixed support rod 33 is fixedly connected to the upper end of the rotating support column 32. At least two snap-fit V-shaped plates 34 are fixedly connected to the outside of the fixed support rod 33. A connecting V-shaped plate 35 is fixedly installed on one side of the snap-fit V-shaped plate 34. The connecting V-shaped plate 35 is fixedly connected to the connecting movable plate 31 through the snap-fit support rod 36. The snap-fit support rod 36 is fixedly installed on the upper end of the connecting movable plate 31. The connecting V-shaped plate 35 is fixedly connected to the snap-fit support rod 36.
[0052] The connecting movable plate 31 is slidably connected to the connecting frame 30, the connecting frame 30 is fixedly connected to the counterweight support frame 1, and the connecting frame 30 is slidably connected to the sliding support shell 29. One end of the connecting frame 30 is inserted into the sliding connecting rod 38 through the sliding support port 39. The sliding support port 39 is opened at one end of the sliding connecting rod 38. Several support frames 37 are fixedly connected to the outside of the snap-fit plate 27, and the several support frames 37 are all inserted into the connecting frame 30.
[0053] When the connecting moving plate 31 moves up and down normally in the counterweight device, it will drive the two connecting V-shaped plates 35 to move simultaneously to the fixed support rod 33 on one side under the support of the snap-fit support rod 36. Thus, under the support of the fixed support rod 33 and the snap-fit V-shaped plate 34, the snap-fit V-shaped plate 34 and the connecting V-shaped plate 35 achieve the effect of snap-fit fixation, so that the connecting moving plate 31 will not move accidentally when the elevator counterweight device moves. When the snap-fit plates 27 on both sides impact and collide with the connecting moving plate 31, the connecting moving plate 31 will collide rapidly, which can break the snap-fit support rod 36, so that the connecting moving plate 31 continues to rotate, achieving the effect of continuing to move the components below.
[0054] This device, by placing the upper end of the rotating support column 32 inside the connecting moving plate 31, ensures the stability of the position and direction of the connecting moving plate 31 when it rotates through the rotational support column 32 supporting the rotation of the connecting moving plate 31 and the positional limitation effect of the connecting moving plate 31 on the rotating support column 32. At the same time, by setting the strength of the snap-fit support rod 36 to be able to support the force generated by the shaking of the connecting moving plate 31 during normal elevator operation, and by ensuring that the snap-fit support rod 36 can break in time when the snap-fit plate 27 collides with the connecting moving plate 31, the stability of the position of the connecting moving plate 31 itself during elevator operation and the reliability of supporting the movement of the components below are ensured.
[0055] In this embodiment, when the support guide shoes 2 at the four corners of the counterweight support frame 1 deform, they will collide with the short sensing columns 3 on the outside or the long sensing columns 45 on the upper and lower sides. After being impacted, the short sensing columns 3 will drive the support connecting plate 4 and the connecting column 6 to move towards the rotating connecting plate 7. This causes the rotating connecting plate 7 to move the pulling rope 18 simultaneously under the connection of the arc-shaped moving plate 12. As a result, the moving block 19 moves downward inside the snap-fit support ring 20, causing the snap-fit support ring 20 to move outward from the snap-fit plate 27. Release the locking effect between the rotating support base plate 21 and the snap-fit support ring 20, allowing the rotating support base plate 21 to move downwards under the rotational support of the snap-fit plate 27. This causes the blocking plate 22 to fall into the support housing 28, and under the elastic action of the two telescopic springs 25, the snap-fit plate 27 moves towards the sliding support frame 46 under the support of the support plate 23. This causes the snap-fit support opening 47 to snap and fix the snap-fit plate 27. At the same time, the connecting moving plate 31 connects the snap-fit plates 27 on both sides. When the snap-fit plate 27 touches... When the movable plate 31 is connected, the movable block 19 moves downward under the connection of the connecting frame 30 and the sliding connecting rod 38, releasing the blocking plate 22 to insert and fix the other side's snap-fit plate 27 and snap-fit support port 47, achieving a multiple buffering effect. When the long sensing column 45 is subjected to impact, it moves outward towards the counterweight support frame 1, thereby driving the connecting frame 30 and the sliding connecting rod 38 towards the movable block 19 under the connection of the connecting rope 41, thus releasing the blocking plate 22 and fixing the snap-fit plate 27 and snap-fit support port 47. The locking effect of the support port 47, through the connection effect of multiple short sensing columns 3 and long sensing columns 45 when the support guide shoe 2 deforms, allows the locking plate 27 to be locked and fixed to the locking support port 47. In addition, the moving support effect of the connecting moving plate 31 and the connecting frame 30 on the two sides of the locking plate 27 allows the locking plate 27 and the sliding support frame 46 to be locked multiple times. When the support guide shoe 2 is connected and tightened, the counterweight support frame 1 and the sliding support frame 46 can be reinforced in time, effectively preventing the counterweight device from falling off.

[0058] The rotating connecting plate 42 is rotatably connected to the counterweight support frame 1 via the rotating support rod 10. The rotating connecting plate 42 is fixedly connected to the rotating support rod 10. An arc-shaped limiting ring 40 is fixedly connected to one side of the counterweight support frame 1. The arc-shaped limiting ring 40 is inserted into the connecting rope 41.
[0059] In this embodiment, during normal elevator operation, the moving blocking plate 44 blocks the moving support block 43, ensuring the stability of the rotating connecting plate 42's position. When the long sensing column 45 is moved by an impact force, the rotating connecting plate 42 will drive the moving support block 43 to push the moving blocking plate 44 aside, allowing the rotating connecting plate 42 to move outward under the rotational support of the rotating support rod 10. This, in turn, under the connection of the connecting rope 41 and the limitation of the arc-shaped limiting ring 40, drives the connecting frame 30 to move, achieving the effect of releasing and engaging the locking device.
[0060] This device, by setting the strength of the movable blocking plate 44 to be able to support the movable support block 43 during normal operation and to be able to break when the long sensing column 45 is impacted, allows the movable support block 43 to move continuously outward, ensuring the stability of the movement of the locking device.
[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
