Description

Technical Field

[0001] The safety protection structure involved in the present invention, in particular, relates to a safety protection structure for an elevator compensation chain applied to the elevator field. Background Art

[0002] As an indispensable vertical transportation device in modern high-rise buildings and public places, the safety and stability of an elevator are directly related to the lives of passengers. In an elevator system, as a key component for balancing the weight change of the steel wire ropes on the car side and the counterweight side, the compensation chain plays an important role in reducing operation noise and preventing derailment risks through the structural design of a metal chain covered with polyvinyl chloride (PVC) or rubber composite material. However, damages such as the breakage or fracture of the outer skin of the compensation chain may cause shaking noise, winding jamming, and even falling risks, posing a serious threat to the safety of elevator rides.

[0003] Regarding the safety issues of the compensation chain, various improvement schemes have been proposed in the prior art: The elevator compensation chain breakage safety protection structure of Chinese invention patent CN115893150B reduces the shaking of the compensation chain by setting a rotating rod structure with an anti-fracture mechanism and using a spring connecting piece, effectively preventing the falling risk caused by chain breakage; The elevator compensation chain safety judgment and protection device and method of Chinese invention patent CN117755938B adopts a technical path that combines electromagnetic force to adjust the pre-tightening force and pressure sensor monitoring to achieve real-time detection of abnormal states of the compensation chain and elevator safety control. The above technologies have improved the safety of the compensation chain from the perspectives of mechanical protection and intelligent monitoring respectively, but their protection mechanisms still have limitations.

[0004] With the popularization of super high-rise buildings and high-speed elevators, the running length of the compensation chain has increased significantly. The prior art has not solved the following core problems: First, the problem of adaptive adjustment of the compensation chain tension during dynamic operation, which is difficult to cope with the load fluctuations caused by the change of the car position; Second, the lateral shaking problem caused by long-distance cyclic movement, resulting in increased noise and an increased risk of well collision; Third, the lack of a collaborative mechanism for multi-dimensional safety prevention and control under complex working conditions. Therefore, how to actively suppress the running posture of the compensation chain and give early warnings of abnormal conditions during its high-speed operation has become a key technical bottleneck for ensuring the safe operation of high-speed elevators. Summary of the Invention

Detailed implementation manners

[0038] The following will make a detailed description of the 3 embodiments of this application with reference to the accompanying drawings.

[0039] The 1st embodiment:

[0040] Figure 1 - Figure 9 A safety protection structure for an elevator compensation chain is shown, including a compensation chain body 1 arranged between the car and the counterweight and a safety protection system installed in the electrical control box. Integrated buffer heads 2 are arranged at both upper ends of the compensation chain body 1. A quick - connection seat 3 is connected to the upper end of the integrated buffer head 2, and the upper ends of the quick - connection seats 3 are respectively fixedly connected to the corresponding car and counterweight. A dynamic tension self - adapting component 4 is arranged at the lower side of the compensation chain body 1 and installed at the bottom of the elevator shaft.

[0041] The safety protection system includes a safety protection processing unit. The input end of the safety protection processing unit is connected to a safety parameter setting unit and a shaking induction unit. The output end of the safety protection processing unit is connected to a dynamic self-adaptive unit. The input end of the safety parameter setting unit is signal-connected to the data interface of the electrical control box. The input end of the shaking induction unit is signal-connected to the integrated buffer head 2. The output end of the dynamic self-adaptive unit is signal-connected to the dynamic tension self-adaptive component 4. Through the cooperation of the integrated buffer head 2, the dynamic tension self-adaptive component 4, the safety protection processing unit, and the dynamic self-adaptive unit, during the operation of the car, it is possible to realize the dynamic self-adaptive regulation of the tension force of the compensation chain body 1, achieve the linkage cooperation effect for the operation of the car, effectively reduce the load fluctuation caused by the change of the car position, reduce the shaking problem of the compensation chain body 1 caused by long-distance cyclic movement, effectively reduce the generation of noise, and avoid the risk of the compensation chain body 1 colliding with the hoistway, ensure the safety of the application of the compensation chain body 1, and also through the synergistic effect of the system, it is possible to effectively realize the functions of active suppression and abnormal warning when the compensation chain body 1 has a risk of fracture, and further effectively ensure the safe operation of the high-rise elevator.

[0042] Figure 1 - Figure 9 It is shown that the dynamic tension self-adaptive component 4 includes a pair of guide plates 41 fixedly arranged at the bottom of the elevator shaft. A dynamic tension guide roller 43 is rotatably connected between the two guide plates 41. A tension induction ring 44 is embedded in the middle of the dynamic tension guide roller 43;

[0043] Self-adaptive long holes 42 are formed on the guide plates 41. The front and rear ends of the dynamic tension guide roller 43 respectively extend to the outside of the corresponding guide plates 41 through the self-adaptive long holes 42 and are rotatably connected with linkage blocks;

[0044] Self-adaptive hydraulic rods 45 are fixedly installed at the far ends of the two guide plates 41. The upper ends of the self-adaptive hydraulic rods 45 are fixedly connected with the linkage blocks;

[0045] A tension pressure sensor is provided inside the tension induction collar 44. The output end of the tension pressure sensor is signal-connected to the dynamic self-adaptive unit, and the output end of the dynamic self-adaptive unit is signal-connected to the self-adaptive hydraulic rod 45. By directly connecting the tension pressure sensor and the self-adaptive hydraulic rod 45 through the dynamic self-adaptive unit, during the real-time monitoring of the attitude of the compensation chain body 1, it is also possible to realize the dynamic self-adaptive regulation function of the compensation chain body 1 according to the change state of its attitude. As the self-adaptive hydraulic rod 45 drives the up and down movement of the dynamic tension guide roller 43, when the tension of the compensation chain body 1 is large, it can be adjusted and released upward, thereby avoiding stress damage and operation failures caused by excessive tension of the compensation chain body 1. When the tension of the compensation chain body 1 is small, it can be adjusted and tightened downward. While effectively ensuring the balance of the compensation chain body 1, the auxiliary car and the counterweight, it can also effectively avoid abnormal sway caused by the compensation chain body 1 being too loose, resulting in an increase in the running noise of the car and the problem of the compensation chain body 1 being entangled with other components in the well. Furthermore, it can fully ensure the application safety of the compensation chain body 1 while promoting the dynamic self-adaptive function during the application process of the compensation chain body 1, and promoting the automation and intelligent safety guarantee function of the compensation chain body 1.

[0046] Figure 4 and Figure 6 - Figure 8 It is shown that a limiting roller 46 is rotatably connected between the guide plates 41 and is located below the dynamic tension guide roller 43. A limiting induction collar 47 is embedded in the middle of the limiting roller 46, and a limiting pressure sensor is provided inside the limiting induction collar 47. The compensation chain body 1 is located between the dynamic tension guide roller 43 and the limiting roller 46 and is in rotational cooperation with the dynamic tension guide roller 43 and the limiting roller 46. The dynamic tension guide roller 43 and the limiting roller 46 form a dual monitoring and dual guiding function for the compensation chain body 1. While dynamically regulating the running state of the compensation chain body 1 and promoting its safety guarantee function during the running of the car, it can also limit the compensation chain body 1 to avoid the situation of the compensation chain body 1 touching the ground due to being too loose or abnormal fracture, further ensuring the durability of the compensation chain body 1 and its safety guarantee function for the balance of the car running.

[0047] Figure 1 and Figure 2It is shown that the input end of the safety protection processing unit is connected with an attitude sensing unit and a fracture warning sensing unit. The input end of the attitude sensing unit is signal-connected with a tension pressure sensor, and the input end of the fracture warning sensing unit is signal-connected with a limit pressure sensor. The coordinated cooperation of the attitude sensing unit and the fracture warning sensing unit can, while promoting the self-adaptive adjustment of the attitude during the operation of the compensation chain body 1, also, when the compensation chain body 1 suddenly moves downward to trigger the fracture warning sensing unit, timely sense and monitor the abnormality of the compensation chain body 1, so as to ensure the continuous safety of the application state of the compensation chain body 1, promote the intelligent safety protection of the application of the compensation chain body 1, and ensure the safety of the application of high-speed elevators.

[0048] Figure 3 and Figure 5 It is shown that the integrated buffer head 2 includes a continuous casting block 21 fixedly connected to the upper end portion of the compensation chain body 1. The upper end of the continuous casting block 21 is fixedly connected with an integrated rod 22, and the upper end of the integrated rod 22 is fixedly connected with a pair of pressing gravity blocks 23;

[0049] The quick connection seat 3 includes a quick connection bottom plate 31, and the quick connection bottom plate 31 is respectively fixedly arranged at the bottoms of the corresponding car and counterweight. The lower end of the quick connection bottom plate 31 is fixedly connected with a quick connection head 32, and an integrated combination hole 33 matching with the integrated rod 22 and the pressing gravity blocks 23 is formed in the quick connection head 32. The integrated cooperation of the integrated buffer head 2 and the quick connection seat 3 can effectively replace the existing installation and application mode of the compensation chain body 1, ensure the stability and safety of the installation connection of the compensation chain body 1, avoid the situation of unhooking of the compensation chain body 1 during application, further ensure the safety of the application of the compensation chain body 1 in high-speed elevators, and also can, through the integrated modular setting method, realize the portability of the maintenance and replacement of the compensation chain body 1, reduce the maintenance difficulty of high-rise elevators, and promote the maintenance efficiency.

[0050] Figure 1 - Figure 3 and Figure 5It is shown that a buffer cylinder 25 sleeved outside the compensation chain body 1 is fixedly connected to the lower end of the continuous casting block 21. An elastic buffer spacer is fixedly connected to the inner wall of the buffer cylinder 25. A chain vibration sensor is arranged inside the elastic buffer spacer. The input end of the shaking induction unit is signal-connected to the chain vibration sensor. The arrangement of the elastic buffer spacer can effectively buffer the shaking of the end of the compensation chain body 1. While cooperating with the dynamic self-adaptive unit to reduce the smoothness of the compensation chain body 1 during operation, it can also effectively isolate and absorb the shaking force, avoid the continuous transmission of the shaking force, further enhance the safety guarantee function of the compensation chain body 1, and through the setting of the shaking induction unit, it can verify the data of the dynamic regulation of the dynamic self-adaptive unit and timely compensate and adjust the dynamic regulation parameters of the dynamic self-adaptive unit, so as to ensure the accuracy and effectiveness of the dynamic regulation and achieve high applicability to the changes in the car operation.

[0051] Figure 1 and Figure 2 It is shown that the input end of the safety protection processing unit is also connected to a car operation acquisition unit. The input end of the car operation acquisition unit is signal-connected to the electrical control system arranged in the electrical control box. The output end of the safety protection processing unit is also connected to a warning transmission unit. The output end of the warning transmission unit is respectively signal-connected to the electrical control system and the alarm arranged in the electrical control box. Through the synergistic effect with the electrical control system, the intelligent synergistic effect between the safety protection system and the car can be realized. It can promote the safety protection system to issue self-adaptive regulation instructions in a timely manner according to the car operation state, enhance the applicability and safety guarantee function of elevators in different operation states and requirements, and at the same time, it can effectively promote the high-precision self-adaptive regulation function of the attitude of the compensation chain body 1, so as to enhance the reliability of the operation and application of the compensation chain body 1, fully guarantee the balance and safety during the car operation, and realize the real-time guarantee and monitoring function of the car.

[0052] Figure 1 - Figure 9When the compensation chain body 1 is applied to a high-speed elevator, technicians input relevant parameter data regarding the attitude safety of the compensation chain body 1 into the safety parameter setting unit through the data interface of the electrical control box. These parameter data include, but are not limited to, the running speed of the high-speed elevator, the running limit height of the high-speed elevator, the rated load of the high-speed elevator, the counterweight mass, the length of the compensation chain body 1, the mass of the compensation chain body 1, the regulation range of the tension of the compensation chain body 1, and the sway safety value of the compensation chain body 1, etc. The safety parameter setting unit converts these data and transmits them to the safety protection processing unit. The safety protection processing unit analyzes and processes these data, and formulates dynamic self-adaptive regulation data regarding the attitude change of the compensation chain body 1, and then transmits the control data to the dynamic self-adaptive unit, so that the subsequent dynamic self-adaptive unit can, according to the pressure data fed back by the tension induction ring 44 on the dynamic tension guide roller 43 by the compensation chain body 1, adjust the height at which the dynamic tension guide roller 43 acts on the compensation chain body 1 through the self-adaptive hydraulic rod 45, thereby realizing the regulation of the tension of the compensation chain body 1.

[0053] During the operation of the high-speed elevator, the compensation chain body 1 undergoes corresponding compensatory movement along with the linkage between the car and the counterweight block. When the pressure exerted by the compensation chain body 1 on the tension induction ring 44 continuously increases, the tension induction ring 44 transmits the pressure data it senses to both the attitude induction unit and the dynamic self-adaptive unit simultaneously. The attitude induction unit determines that the compensation chain body 1 is in a continuously tensioned state at this time. The dynamic self-adaptive unit generates an action instruction for the self-adaptive hydraulic rod 45 based on the pressure data feedback of the tension induction ring 44, causing the self-adaptive hydraulic rod 45 to drive the dynamic tension guide roller 43 to move upward, and then exert an upward release effect on the compensation chain body 1, thereby avoiding the situation where the resistance between the compensation chain body 1 and the dynamic tension guide roller 43 increases due to the continuous tensioning of the compensation chain body 1, ensuring the balance effect of the compensation chain body 1 on the car operation, and effectively reducing the frictional damage of the compensation chain body 1, promoting the durability of the compensation chain body 1. As the self-adaptive hydraulic rod 45 drives the upward release effect of the dynamic tension guide roller 43, the pressure of the tension induction ring 44 reaches release, and then the pressure data is transmitted to the attitude induction unit and the dynamic self-adaptive unit simultaneously. After the pressure data transmitted by the tension induction ring 44 reaches the standard range, the dynamic self-adaptive unit stops the regulation of the self-adaptive hydraulic rod 45;

[0054] When the pressure exerted by the compensation chain body 1 on the tension sensing collar 44 continuously decreases, the tension sensing collar 44 transmits the pressure data it senses to the attitude sensing unit and the dynamic self - adapting unit simultaneously. The attitude sensing unit determines that the compensation chain body 1 is in a continuously slack state at this time. The dynamic self - adapting unit generates an action instruction for the self - adapting hydraulic rod 45 based on the feedback of the pressure data of the tension sensing collar 44, causing the self - adapting hydraulic rod 45 to drive the dynamic tension guide roller 43 to move downward, thereby performing a downward tensioning action on the compensation chain body 1, so as to avoid the continuous slack of the compensation chain body 1, which may cause it to shake and entangle other components in the well, and thus avoid the generation of noise during the operation of the high - speed elevator, ensuring the safety during the application of the compensation chain body 1. As the self - adapting hydraulic rod 45 drives the dynamic tension guide roller 43 to perform the downward tensioning action, the pressure of the tension sensing collar 44 gradually recovers, and then the pressure data is transmitted to the attitude sensing unit and the dynamic self - adapting unit simultaneously. After the pressure data transmitted by the tension sensing collar 44 reaches the standard range, the dynamic self - adapting unit stops the regulation of the self - adapting hydraulic rod 45;

[0055] The attitude sensing unit transmits the pressure change data of the tension sensing collar 44 to the safety protection processing unit. The safety protection processing unit can judge the attitude change data of the compensation chain body 1 during the operation of the car based on the feedback data. At the same time, during the operation of the high - speed elevator, the car operation acquisition unit can obtain the operation state data of the car through the data transmitted by the electrical control system and transmit this data to the safety protection processing unit. The safety protection processing unit can judge the regulation effect of the dynamic self - adapting unit based on the operation state data of the car and the attitude change data of the compensation chain body 1, then fine - tune and compensate the dynamic self - adapting regulation data regarding the attitude change of the compensation chain body 1, and then transmit the compensation data to the dynamic self - adapting unit, enabling it to perform an autonomous regulation effect on the compensation chain body 1 according to the operation state data of the car during the subsequent operation of the car, thereby promoting the tensioning effectiveness of the compensation chain body 1 during operation, promoting the automation and intelligentization of the compensation chain body 1 during operation, and fully ensuring the safety of the application of the high - speed elevator;

[0056] And during the continuous application of the compensation chain body 1 and the dynamic self - adapting unit, the swaying induction unit can also collect the swaying data of the compensation chain body 1 during operation through the chain vibration sensor arranged at the position of the continuous casting block 21. Since the data is directly collected from the elastic buffer spacer sleeve arranged outside the end of the compensation chain body 1, the authenticity of the swaying data of the compensation chain body 1 can be effectively guaranteed. Then, according to the relevant vibration data, the dynamic self - adapting regulation data for the attitude change of the compensation chain body 1 is further regulated and compensated, and the compensation data is transmitted to the dynamic self - adapting unit, which can further ensure the effectiveness of its dynamic self - adapting regulation of the attitude of the compensation chain body 1, ensure its safety protection function during the application of the car, and also realize the real - time adaptability of the dynamic self - adapting unit to the attitude of the compensation chain body 1, promoting the smoothness and safety of the operation of the compensation chain body 1.

[0057] And during the continuous operation of the compensation chain body 1, when it breaks abnormally, the compensation chain body 1 will be in an over - relaxed state, which will directly act on the limit roller 46, so that the limit induction ring 47 on the limit roller 46 can sense the pressure data of the compensation chain body 1 and transmit it to the fracture warning induction unit. The fracture warning induction unit transmits the data to the safety protection processing unit. After receiving the fracture warning data, the safety protection processing unit verifies the data transmitted by the attitude induction unit. After judging that the compensation chain body 1 is in an over - relaxed state, it directly sends a warning signal to the warning transmission unit, so that the warning transmission unit sends abnormal data to the electrical control system. The electrical control system timely provides safety protection for the running car. After the operation instruction is completed, it controls the high - speed elevator to suspend operation, and at the same time sends abnormal data to the elevator maintenance platform, facilitating the maintenance personnel to maintain it in time, and also avoiding the safety risks caused by the continuous operation of the high - speed elevator. The warning transmission unit will also activate the alarm in the electrical control box to send an alarm reminder to the staff in the elevator operation area, enabling them to timely protect the abnormal high - speed elevator and avoid the danger caused by continuous passenger carrying.

Through the cooperation of the shaking sensing unit and the installed vibration sensor, the connection stability between the integrated buffer head 2 and the quick connection seat 3 can be monitored. While promoting the operation stability and safety of the compensation chain body 1, it can also fully guarantee the effectiveness of the connection state of the compensation chain body 1, ensure the connection stability between the compensation chain body 1 and the car and the counterweight respectively, and then ensure the effectiveness of the subsequent continuous application of the compensation chain body 1. And the safety protection processing unit can also judge the effectiveness of the dynamic regulation data for the compensation chain body 1 according to the feedback data of the connection stability, realize the further compensation and regulation of the dynamic regulation data, can collect the attitude data of the compensation chain body 1 in multiple dimensions, so as to improve the high precision and high reliability of its safety guarantee function, fully ensure its safety guarantee function during the operation of the car, promote the application effect of the compensation chain body 1, and can also realize the flexible locking function of the pressing gravity block 23 through the elastic action of the elastic air bag 51, buffer its shaking effect during its shaking process, avoid rigid damage to the pressing gravity block 23, and fully ensure the effectiveness and safety of the installation of the compensation chain body 1.

[0061] Figure 1 - Figure 12 It is shown that during the operation of the high-speed elevator, the shaking sensing unit can also collect real-time data from the vibration sensor installed at the pressing gravity block 23, and collect the shaking data at the joint of the integrated buffer head 2 and the quick connection seat 3 through the vibration sensor. In this way, during the process of the dynamic self-adaptive unit performing dynamic self-adaptive regulation on the tensioning effect of the compensation chain body 1, the execution state of the regulation data of the dynamic self-adaptive unit can be monitored and verified, and then according to the relevant vibration data, the dynamic self-adaptive regulation data regarding the attitude change of the compensation chain body 1 can be further regulated and compensated, and the compensation data is transmitted to the dynamic self-adaptive unit, which can further ensure the effectiveness of its dynamic self-adaptive regulation of the attitude of the compensation chain body 1, guarantee its safety protection function during the application of the car, and can also realize the real-time adaptability of the dynamic self-adaptive unit to the attitude of the compensation chain body 1, and promote the smoothness and safety of the operation of the compensation chain body 1.

[0062] The 3rd implementation method:

[0063] Figure 1 - Figure 12Show a safety protection structure for an elevator compensation chain. Anti - detachment support plates 52 are fixedly connected to both the left and right ends of the quick - connection head 32. An anti - detachment guiding groove is formed at one end of the anti - detachment support plate 52 close to the integrated rod 22. An anti - detachment abutting plate 54 is slidably arranged in the anti - detachment guiding groove. A reverse air bag 53 is fixedly connected to the end of the anti - detachment abutting plate 54 away from the integrated rod 22, and the end of the reverse air bag 53 away from the integrated rod 22 is fixedly arranged in the anti - detachment guiding groove. The elastic air bag 51 is connected to the reverse air bag 53 through a drainage branch pipe. A plurality of auxiliary elastic members can be fixedly installed between the upper and lower inner walls of the elastic air bag 51, and a restoring elastic member can be installed between the left and right inner walls of the reverse air bag 53. Thus, under the action of their own elastic forces, the elastic air bag 51 and the reverse air bag 53 can be assisted in elastic recovery and deformation guidance, so as to ensure their action effects. In the free state, the elastic air bag 51 is in an extended state and the reverse air bag 53 is in a contracted state. A limiting support ring 24 is fixedly connected to the outer end of the integrated rod 22 and is arranged above the anti - detachment abutting plate 54. The combined action of the elastic air bag 51, the reverse air bag 53 and the anti - detachment abutting plate 54 can effectively utilize the self - weight of the compensation chain body 1 and the pressing gravity block 23 to promote the connection stability, achieve the self - weight locking function, ensure the effectiveness of the connection between the compensation chain body 1 and the car and the counterweight respectively, and can also realize the further anti - unhooking function of the integrated buffer head 2 through the cooperation of the anti - detachment abutting plate 54 and the limiting support ring 24, fully ensuring the safety of the installation and locking of the compensation chain body 1 and promoting the effectiveness of its connection.

[0064] Figure 5 and Figure 10 - Figure 12 Show that the elastic air bag 51 remains in an extended state without external force, and the extended length of the elastic air bag 51 is 0.7 - 0.8 times the height of the waist groove. By displaying the length of the self - weight reverse anti - detachment component 5 in the extended state, it can effectively avoid the abutting and pressing action on the pressing gravity block 23, so as to ensure the portability of the disassembly and installation between the integrated buffer head 2 and the quick - connection seat 3, and promote the application portability of the compensation chain body 1.

[0065] Figure 1 - Figure 12When it is necessary to maintain or replace the compensation chain body 1, the quick-connect head 32 is fixed to the bottoms of the corresponding car and counterweight through the quick-connect bottom plate 31. The maintenance personnel hold the pressing gravity block 23 at the position of the continuous casting block 21 in a front-back distribution, and then insert the integrated rod 22 and the pressing gravity block 23 into the integrated combination hole 33. The pressing gravity block 23 is inserted into the integrated combination hole 33 through cooperation with the perforation through groove, and the integrated rod 22 is inserted into the integrated combination hole 33 through cooperation with the transition hole groove. When the integrated rod 22 moves to the upper side of the transition hole groove, rotate the continuous casting block 21 to drive the integrated rod 22 and the pressing gravity block 23 to rotate, rotate the pressing gravity block 23 into the waist groove and locate it above the top plate. Then the maintenance personnel release the continuous casting block 21, so that the pressing gravity block 23 presses the elastic air bag 51 under the action of the self-weight of the compensation chain body 1 and the pressing gravity block 23, and is locked in the waist groove, effectively realizing the quick disassembly and assembly of the compensation chain body 1 and promoting the portability of the application of the compensation chain body 1.

[0066] Then, after the elastic air bag 51 is compressed, the gas inside it will be transmitted to the reverse air bag 53 through the drainage branch pipe, causing the reverse air bag 53 to produce an elongation deformation and pushing the anti-disconnection bottom plate 54 to move outside the anti-disconnection guiding groove and under the limiting support ring 24, which can play a further installation insurance role for the compensation chain body 1 in the follow-up. In the case where the integrated rod 22 accidentally breaks in the follow-up, under the continuous abutting action of the pressing gravity block 23, the contraction of the elastic air bag 51 is maintained, realizing the further locking of the anti-disconnection bottom plate 54 to the limiting support ring 24, playing an emergency role in preventing the compensation chain body 1 from being disconnected and further ensuring the application and installation of the compensation chain body 1.

[0067] Moreover, when the compensation chain body 1 shakes due to a temporary imbalance of the tension force or the operation transmission of the car, under the force transmission of the compensation chain body 1, it will act on the pressing gravity block 23 through the continuous casting block 21. The pressing gravity block 23 utilizes the elasticity of the elastic air bag 51 to buffer and offset the shaking effect. Through the flexible locking effect, the rigid damage of the pressing gravity block 23 in the integrated combination hole 33 is effectively reduced, ensuring the effectiveness and safety of its connection. And under the transmission of the shaking force of the car, the elastic buffer spacer in the buffer cylinder 25 can offset the shaking effect transmitted to the compensation chain body 1, reduce the transmission of the shaking effect, maintain the stability of the compensation chain body 1, reduce the application damage of the compensation chain body 1, and promote its role in ensuring the balance and safety of the car during operation.

[0068] Combined with the current actual needs, the above-described implementation manner adopted in this application, the protection scope is not limited thereto. Within the knowledge range of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
