Description

Technical Field

[0001] This utility model belongs to the field of mining elevator testing technology, specifically relating to a connection structure for a mining elevator brake testing device. Background Technology

[0002] With the safety of mining elevators being of paramount importance, braking distance testing is a crucial aspect of evaluating elevator performance and safety. However, traditional methods for testing braking distance in mining elevators have numerous drawbacks, severely impacting testing effectiveness and elevator safety management. Some inspections rely on manual measurement. After the mine elevator stops running, the inspectors need to manually measure the positional changes of relevant components to estimate the braking distance. This method is greatly affected by human factors, such as the limited accuracy of measuring tools, differences in operator operation, and perspective deviation. Using mine elevator braking inspection equipment can solve these problems. However, the magnetoelectric sensors used in mine elevator braking inspection equipment are prone to displacement and loosening. Summary of the Invention

[0003] The purpose of this invention is to provide a connection structure for a braking detection device for a mining elevator, which ensures that the magnetoelectric sensor does not shift or loosen during elevator operation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: The connection structure for the mine elevator brake detection equipment includes: The first card block, there are four first card blocks, and the four first card blocks are respectively fixedly connected to the four fixing holes; The four convex slots are respectively located at the far ends of the four first blocks; The mounting base has four limiting grooves, which are respectively located at both ends of the mounting base. The springs are provided in four parts, and one end of each of the four springs is fixedly connected to the inner wall of the four limiting grooves that are close to each other. The slider is provided in four parts, and the four sliders are slidably connected in four limiting grooves respectively, and the four sliders are fixedly connected to the other end of four springs respectively. The slide bar is provided in four parts, and the four slide bars are respectively fixedly connected to the far ends of the four sliders; The card plate is provided in four parts, and the four card plates are respectively fixedly connected to the far ends of four sliding rods; The second card block, which has four parts, is fixedly connected to the far ends of the four card plates respectively. The card plates and the second card blocks are respectively movably engaged in the four convex slots.

[0005] Furthermore, the four card plates and four second card blocks combined form a convex shape.

[0006] Furthermore, the mounting base has four positioning holes and four threaded holes at its front and rear ends, respectively.

[0007] Compared with existing technologies, the design of the connection mechanism of this utility model ensures that the magnetoelectric sensor does not shift or loosen during elevator operation. For example, the springs, sliders, clamping plates, and convex grooves in the connection mechanism work together to provide a firm connection while also having a certain degree of elasticity and buffering function. This effectively copes with the vibration and impact during elevator operation and avoids component damage that may be caused by rigid connections. The reasonable design and coordinated work of each component enable the equipment to operate stably in complex elevator operating environments, extend the service life of the equipment, further ensure the continuous and accurate conduct of elevator testing, and enhance the safety and reliability of elevator operation.

[0010] 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.

[0011] Example 1: Please refer to Figures 1-4 This is a connection structure for a mine elevator braking detection device. The connection mechanism is located on the rear side of the magnetoelectric sensor 1. Through cooperation with the rectangular slot 7 and the fixing hole structure, the magnetoelectric sensor 1 is firmly connected and fixed to the mounting base 9, ensuring that the magnetoelectric sensor 1 does not shift or loosen during elevator operation, thus ensuring accurate and stable speed detection. The mounting base 9 is installed on the rotating shaft of the elevator traction machine, enabling real-time and accurate measurement of the traction machine's rotation speed, thereby obtaining the elevator's running speed. The laser rangefinder sensor 3 is installed on the top of the elevator car, vertically aligned with the fixed reflector at the bottom of the elevator shaft. By measuring the laser's round-trip time, the car displacement is accurately calculated. It should be noted that the specific model of the magnetoelectric sensor 1, the intelligent display screen 2, and the laser rangefinder sensor 3 used is selected by those skilled in the art, and the above-mentioned magnetoelectric sensor 1, intelligent display screen 2, and laser rangefinder sensor 3 are all existing technologies, which will not be elaborated upon in this solution.

[0012] Please refer to the details. Figures 1-4 The connecting mechanism includes: The first locking block 8, there are four first locking blocks 8, and the four first locking blocks 8 are respectively fixedly connected to the four fixing holes; The four convex slots 801 are respectively located at the far ends of the four first card blocks 8. The four limiting grooves 10 are respectively opened at both ends of the mounting base 9. Spring 11, four springs 11 are provided, and one end of each of the four springs 11 is fixedly connected to the inner wall of the four limiting grooves 10 that are close to each other; Slider 12, four sliders 12 are provided, the four sliders 12 are slidably connected in the four limiting grooves 10 respectively, and the four sliders 12 are fixedly connected to the other end of the four springs 11 respectively; There are four slide rods 13, and the four slide rods 13 are respectively fixedly connected to the far ends of the four sliders 12; Four card plates 14 are provided, and the four card plates 14 are respectively fixedly connected to the far ends of the four slide rods 13; The second card block 15, there are four second card blocks 15, and the four second card blocks 15 are respectively fixedly connected to the far ends of the four card plates 14. The card plates 14 and the second card blocks 15 are respectively movably engaged in the four convex card slots 801.

[0013] In this embodiment: when installing the magnetoelectric sensor 1 onto the rotating shaft of the elevator traction machine, firstly, align the mounting base 9 of the magnetoelectric sensor 1 with the mounting position of the rotating shaft, and simultaneously fix the four first locking blocks 8 into the four fixing holes respectively. At this time, the locking plate 14 and the second locking block 15 are in an extended state under the elastic force of the spring 11, that is, the spring 11 is at or close to its natural length.

[0014] Next, push the magnetoelectric sensor 1 so that the four locking plates 14 and the second locking block 15 on the mounting base 9 are aligned with the convex slot 801 on the first locking block 8. Continue to push the magnetoelectric sensor 1 so that the locking plates 14 and the second locking block 15 will contact the external opening of the convex slot 801.

[0015] As the push continues, the locking plate 14 and the second locking block 15 compress the spring 11, causing the slider 12 to slide within the limiting groove 10. The spring 11 is compressed, providing sufficient retraction space for the locking plate 14 and the second locking block 15 until they are fully inserted into the convex groove 801. Once the locking plate 14 and the second locking block 15 reach the appropriate position in the convex groove 801, the elastic force of the spring 11 will eject the locking plate 14 and the second locking block 15 outward, securing them firmly within the convex groove 801, thus completing the connection between the magnetoelectric sensor 1 and the mounting base 9.

[0016] When it is necessary to disassemble the magnetoelectric sensor 1, apply external force to push the card plate 14 and the second card block 15 inward, so that they are dislodged from the convex card groove 801. At this time, the slider 12 will slide in the limiting groove 10 and compress the spring 11. When the card plate 14 and the second card block 15 are completely dislodged from the convex card groove 801, the magnetoelectric sensor 1 can be removed from the mounting base 9.

[0017] During elevator operation, due to the elasticity of spring 11 and the engaging action of the locking plate 14 and the second locking block 15 with the convex locking groove 801, the magnetoelectric sensor 1 is firmly fixed on the mounting base 9, preventing loosening or displacement due to vibration, rotation, or other factors. This ensures stable operation of the magnetoelectric sensor 1 and guarantees the accuracy of speed measurement. Simultaneously, because the connecting mechanism has a certain degree of elasticity and buffering function, it can buffer external impacts or vibrations by sliding the slider 12 within the limiting groove 10 and by extending and retracting the spring 11, preventing damage to components caused by rigid connections.

[0018] Example 2: Please refer to Figures 1-4 Mining elevator brake testing equipment, including: The magnetoelectric sensor 1 has a laser rangefinder 3 on its upper side. A smart display screen 2 is fixedly connected to one side of the magnetoelectric sensor 1. The laser rangefinder 3 is installed on a fixed reflector that is vertically downward and aligned with the bottom of the elevator shaft on the top of the elevator car. The smart display screen 2 contains a data processing unit, a display and alarm module, and a power supply module. Two rectangular slots 7 are provided, and the two rectangular slots 7 are respectively opened at both ends of the magnetoelectric sensor 1; There are four fixing holes, which are respectively opened on the rear inner wall of the two rectangular grooves 7; Mounting base 9, located on the rear side of the magnetoelectric sensor 1, is mounted on the rotating shaft of the elevator traction machine; and A connecting mechanism is located on the rear side of the magnetoelectric sensor 1. The connecting mechanism is used to connect and fix the magnetoelectric sensor 1.

[0019] In a specific embodiment of this utility model, the magnetoelectric sensor 1 is based on the principle of electromagnetic induction, which converts the mechanical rotation of the elevator traction machine's rotating shaft into an electrical signal, and measures the traction machine's rotation speed in real time and accurately, providing data for obtaining the elevator's running speed.

[0020] The laser rangefinder 3 is installed on the top of the elevator car and vertically aligned with a fixed reflector at the bottom of the elevator shaft. By measuring the time it takes for the laser to travel from emission to reflection back from the reflector, the change in distance between the car and the reflector is accurately calculated, obtaining elevator car displacement information and providing crucial data for calculating the braking distance.

[0021] The intelligent display screen 2 integrates a data processing unit, a display and alarm module, and a power supply module. The data processing unit receives and processes data from the magnetoelectric sensor 1 and the laser rangefinder sensor 3, using algorithms to calculate the elevator's acceleration and braking distance during braking. The display and alarm module displays real-time elevator speed, braking acceleration, braking distance, and other parameters on the screen. When the braking distance exceeds the safety standard range, it issues an audible and visual alarm signal. The power supply module provides stable power to the intelligent display screen 2 and all related functional modules.

[0022] Two rectangular slots 7 are respectively opened at both ends of the magnetoelectric sensor 1 to provide installation positions and positioning references for the connection mechanism, ensuring the stable operation of the magnetoelectric sensor 1.

[0023] Two fixing holes are provided on the rear inner wall of each of the two rectangular slots 7. These holes allow for secure connection to other components such as connecting mechanisms or mounting bases 9 via bolts, screws, or other fasteners, enhancing the stability of the connection between the magnetoelectric sensor 1 and other components.

[0024] Mounting base 9 is located on the rear side of magnetoelectric sensor 1 and is installed on the rotating shaft of the elevator traction machine. It fixes the position of magnetoelectric sensor 1 so that magnetoelectric sensor 1 can accurately follow the rotating shaft of the elevator traction machine to rotate synchronously and accurately measure the rotation speed.

[0025] The connecting mechanism is located on the rear side of the magnetoelectric sensor 1. Through cooperation with the rectangular slot 7 and the fixing hole structure, the magnetoelectric sensor 1 is firmly connected and fixed to the mounting base 9, ensuring that the magnetoelectric sensor 1 does not shift or loosen during elevator operation, thus ensuring accurate and stable speed detection. The mounting base 9 is installed on the rotating shaft of the elevator traction machine, enabling real-time and accurate measurement of the traction machine's rotation speed, thereby obtaining the elevator's operating speed. The laser rangefinder 3 is installed on the top of the elevator car, vertically aligned with the fixed reflector at the bottom of the elevator shaft. It accurately calculates the car displacement by measuring the laser's round-trip time. It should be noted that the specific model of the magnetoelectric sensor 1, the intelligent display screen 2, and the laser rangefinder 3 used is to be selected by those skilled in the art. Furthermore, the magnetoelectric sensor 1, the intelligent display screen 2, and the laser rangefinder 3 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0026] Please refer to the details. Figures 1-4 The connecting mechanism includes: The first locking block 8, there are four first locking blocks 8, and the four first locking blocks 8 are respectively fixedly connected to the four fixing holes; The four convex slots 801 are respectively located at the far ends of the four first card blocks 8. The four limiting grooves 10 are respectively opened at both ends of the mounting base 9. Spring 11, four springs 11 are provided, and one end of each of the four springs 11 is fixedly connected to the inner wall of the four limiting grooves 10 that are close to each other; Slider 12, four sliders 12 are provided, the four sliders 12 are slidably connected in the four limiting grooves 10 respectively, and the four sliders 12 are fixedly connected to the other end of the four springs 11 respectively; There are four slide rods 13, and the four slide rods 13 are respectively fixedly connected to the far ends of the four sliders 12; Four card plates 14 are provided, and the four card plates 14 are respectively fixedly connected to the far ends of the four slide rods 13; The second card block 15, there are four second card blocks 15, and the four second card blocks 15 are respectively fixedly connected to the far ends of the four card plates 14. The card plates 14 and the second card blocks 15 are respectively movably engaged in the four convex card slots 801.

[0027] In this embodiment: when installing the magnetoelectric sensor 1 onto the rotating shaft of the elevator traction machine, firstly, align the mounting base 9 of the magnetoelectric sensor 1 with the mounting position of the rotating shaft, and simultaneously fix the four first locking blocks 8 into the four fixing holes respectively. At this time, the locking plate 14 and the second locking block 15 are in an extended state under the elastic force of the spring 11, that is, the spring 11 is at or close to its natural length.

[0028] Next, push the magnetoelectric sensor 1 so that the four locking plates 14 and the second locking block 15 on the mounting base 9 are aligned with the convex slot 801 on the first locking block 8. Continue to push the magnetoelectric sensor 1 so that the locking plates 14 and the second locking block 15 will contact the external opening of the convex slot 801.

[0029] As the push continues, the locking plate 14 and the second locking block 15 compress the spring 11, causing the slider 12 to slide within the limiting groove 10. The spring 11 is compressed, providing sufficient retraction space for the locking plate 14 and the second locking block 15 until they are fully inserted into the convex groove 801. Once the locking plate 14 and the second locking block 15 reach the appropriate position in the convex groove 801, the elastic force of the spring 11 will eject the locking plate 14 and the second locking block 15 outward, securing them firmly within the convex groove 801, thus completing the connection between the magnetoelectric sensor 1 and the mounting base 9.

[0030] When it is necessary to disassemble the magnetoelectric sensor 1, apply external force to push the card plate 14 and the second card block 15 inward, so that they are dislodged from the convex card groove 801. At this time, the slider 12 will slide in the limiting groove 10 and compress the spring 11. When the card plate 14 and the second card block 15 are completely dislodged from the convex card groove 801, the magnetoelectric sensor 1 can be removed from the mounting base 9.

[0031] During elevator operation, due to the elasticity of spring 11 and the engaging action of the locking plate 14 and the second locking block 15 with the convex locking groove 801, the magnetoelectric sensor 1 is firmly fixed on the mounting base 9, preventing loosening or displacement due to vibration, rotation, or other factors. This ensures stable operation of the magnetoelectric sensor 1 and guarantees the accuracy of speed measurement. Simultaneously, because the connecting mechanism has a certain degree of elasticity and buffering function, it can buffer external impacts or vibrations by sliding the slider 12 within the limiting groove 10 and by extending and retracting the spring 11, preventing damage to components caused by rigid connections.

[0032] Please refer to the details. Figures 1-3 A connecting plate 4 is fixedly connected to the outer surface of the laser rangefinder 3, and four mounting holes 401 are opened at the top of the connecting plate 4.

[0033] In this embodiment, the connecting plate 4 is fixedly connected to the outer surface of the laser rangefinder 3, and its main function is to provide an extended platform for connecting the laser rangefinder 3. Four mounting holes 401 are formed at the top of the connecting plate 4. Through these mounting holes 401, bolts, screws, and other connectors can be used to install the laser rangefinder 3 at a suitable position on the top of the elevator car. For example, bolts can be passed through the mounting holes 401 and tightened at the corresponding positions pre-set on the top of the car to ensure that the laser rangefinder 3 is firmly fixed to the top of the car and can be vertically aligned with the fixed reflector at the bottom of the elevator shaft.

[0034] Please refer to the details. Figure 2 A wiring hole 6 is provided on one side of the laser rangefinder sensor 3, and four plastic pads 5 are fixedly connected to the top of the connecting plate 4.

[0035] In this embodiment, the plastic pad 5 is fixedly connected to the top of the connecting plate 4, and its function is to buffer and dampen vibrations. After the laser rangefinder sensor 3 is installed, when the elevator vibrates during operation, the plastic pad 5 can absorb some of the vibration energy, reduce the impact of vibration on the laser rangefinder sensor 3, and prevent damage to the internal components of the laser rangefinder sensor 3 or a decrease in measurement accuracy due to excessive vibration.

[0036] The wiring hole 6 on one side of the laser rangefinder sensor 3 is mainly used for leading out and wiring the internal circuitry of the laser rangefinder sensor 3. When installing the laser rangefinder sensor 3, its internal signal transmission lines, power lines, and other cables are led out through the wiring hole 6 so that the laser rangefinder sensor 3 can be connected to components such as the data processing unit inside the smart display screen 2.

[0037] Please refer to the details. Figures 1-4 The four card plates 14 and the four second card blocks 15 are combined in a convex shape.

[0038] In this embodiment: when connecting the magnetoelectric sensor 1 and the mounting base 9, the convex structure formed by the locking plate 14 and the second locking block 15 is aligned with the convex slot 801 on the first locking block 8. When the locking plate 14 and the second locking block 15 are inserted into the convex slot 801, due to the special structure of the convex shape, the elastic force of the spring 11 prevents the locking plate 14 and the second locking block 15 from easily coming out of the convex slot 801, thereby ensuring the firmness of the connection.

[0039] Please refer to the details. Figures 1-3 An anti-slip pad 101 is fixedly connected to the rear end of the magnetoelectric sensor 1.

[0040] In this embodiment, the anti-slip pad 101 is fixedly connected to the rear end of the magnetoelectric sensor 1. Its main function is to increase the friction between the magnetoelectric sensor 1 and the mounting base 9 or other adjacent components. During elevator operation, the rotating shaft of the elevator traction machine will vibrate and rotate. The anti-slip pad 101 can prevent the magnetoelectric sensor 1 from shifting or rotating due to vibration, ensuring that the magnetoelectric sensor 1 maintains a stable installation position on the mounting base 9, thereby improving its operational reliability and the accuracy of the measurement data.

[0041] Please refer to the details. Figures 1-4 The mounting base 9 has four positioning holes 902 and four threaded holes 901 at its front and rear ends, respectively.

[0042] In this embodiment, the mounting base 9 has four positioning holes 902 and four threaded holes 901 at its front and rear ends, respectively. The positioning holes 902 are used to position and pre-install the mounting base 9 when it is installed onto the rotating shaft of the elevator traction machine, ensuring the accurate installation position of the mounting base 9 and the rotating shaft. Positioning pins or other positioning components can be used to pass through the positioning holes 902 to ensure the installation accuracy of the mounting base 9 and avoid eccentricity or angular deviation.

[0043] The threaded hole 901 is mainly used to securely fix the mounting base 9 to the rotating shaft of the elevator traction machine using bolts. After the mounting base 9 is accurately positioned, the bolts are screwed into the threaded hole 901 and tightened to firmly fix the mounting base 9 to the rotating shaft. This ensures that after the magnetoelectric sensor 1 is connected to the mounting base 9 through the connecting mechanism, it can stably follow the rotation of the rotating shaft, thereby ensuring the accuracy of the magnetoelectric sensor 1 in measuring the speed of the traction machine.

[0044] The working principle and usage process of this utility model are as follows: First, prepare for installation. For the magnetoelectric sensor 1, the mounting base 9 should be aligned with the mounting pin through the positioning holes 902 at both ends of the mounting base 9 to accurately align with the installation position of the elevator traction machine rotating shaft to achieve initial positioning. At the same time, the four first locking blocks 8 are fixed in the four fixing holes on the inner wall of the rectangular grooves 7 at both ends of the magnetoelectric sensor 1. At this time, the locking plate 14 and the second locking block 15 in the connecting mechanism are in an extended state under the action of the spring 11. For the laser ranging sensor 3, it is necessary to carefully check whether the four mounting holes 401 at the top of the connecting plate 4 and the wiring hole 6 on one side are unobstructed, and whether the four plastic pads 5 fixedly connected on the connecting plate 4 are installed firmly.

[0045] Next, the magnetoelectric sensor 1 is installed. The magnetoelectric sensor 1, equipped with the mounting base 9 and connecting mechanism, is slowly pushed towards the rotating shaft of the elevator traction machine. During this process, the four locking plates 14 and the second locking block 15 on the mounting base 9 must be accurately aligned with the convex groove 801 on the first locking block 8. As the sensor is continuously pushed, the locking plates 14 and the second locking block 15 contact the outer opening of the convex groove 801, compressing the spring 11 and causing the slider 12 to slide within the limiting groove 10. The spring 11 is gradually compressed, thus allowing the locking plates 14 and the second locking block 15 to move freely within the limiting groove 10. 5. Provide sufficient retraction space until the card plate 14 and the second card block 15 are fully inserted into the convex slot 801. At this time, the elastic force of the spring 11 will push the card plate 14 and the second card block 15 outward, so that they are firmly locked in the convex slot 801, completing the connection between the magnetoelectric sensor 1 and the mounting base 9. Then, screw the bolt into the threaded hole 901 on the mounting base 9 to fix the mounting base 9 tightly on the rotating shaft of the elevator traction machine, ensuring that the magnetoelectric sensor 1 can stably follow the rotating shaft to achieve accurate measurement of the traction machine speed.

[0046] Then, install the laser rangefinder sensor 3. Using the four mounting holes 401 at the top of the connecting plate 4, use bolts or screws to pass through the mounting holes 401 and tighten them to the corresponding positions pre-set on the top of the elevator car. Securely install the laser rangefinder sensor 3 on the top of the car, ensuring that it is vertically aligned with the fixed reflector at the bottom of the elevator shaft. At the same time, lead out the signal transmission line, power line, and other cables inside the laser rangefinder sensor 3 through the wiring hole 6 and connect them to the data processing unit and other related components in the intelligent display screen 2 according to the wiring specifications to ensure the stability and reliability of data transmission.

[0047] Finally, the equipment operation and testing phase begins. When the elevator is running, the magnetoelectric sensor 1, based on the principle of electromagnetic induction, converts the mechanical rotation of the elevator traction machine's rotating shaft into an electrical signal in real time, accurately measuring the traction machine's speed and transmitting the data to the data processing unit within the intelligent display screen 2. Simultaneously, the laser rangefinder sensor 3 continuously emits laser light towards a fixed reflector at the bottom of the elevator shaft and receives the reflected light. By measuring the laser's round-trip time, it accurately calculates the distance change between the car and the reflector, obtaining the car's displacement information, which is also transmitted to the data processing unit. After receiving data from the magnetoelectric sensor 1 and the laser rangefinder sensor 3, the data processing unit uses a built-in algorithm to calculate the elevator's acceleration and braking distance during braking. It then transmits parameters such as the elevator's real-time speed, braking acceleration, and braking distance to the display and alarm module. This module displays these parameters on the intelligent display screen 2 for staff to view. If the braking distance exceeds the preset safety standard range, the alarm module immediately issues an audible and visual alarm signal, reminding relevant personnel to promptly inspect and maintain the elevator to ensure safe operation.

[0048] In summary, the advantages of mine elevator brake testing equipment are as follows: 1. By integrating a high-precision magnetoelectric sensor with an advanced laser rangefinder, the system achieves accurate measurement of elevator traction machine speed and car displacement. The magnetoelectric sensor, based on the principle of electromagnetic induction, can accurately convert the mechanical rotation of the elevator traction machine's rotating shaft into an electrical signal in real time, providing accurate data for obtaining elevator operating speed. The laser rangefinder is installed on the top of the elevator car and vertically downwards, aligned with a fixed reflector at the bottom of the elevator shaft. It can accurately calculate car displacement information, providing key data for calculating braking distance. After processing by the efficient data processing unit within the intelligent display screen, the precise braking distance can be obtained, effectively improving detection accuracy and providing a reliable basis for accurately assessing elevator safety performance.

[0049] 2. The components work closely together and are easy to install, changing the traditional cumbersome manual measurement method. During installation, the magnetoelectric sensor is tightly connected to the mounting base through a unique connection mechanism. The positioning holes and threaded holes of the mounting base ensure accurate installation on the rotating shaft of the elevator traction machine, improving installation efficiency and sensor stability. The laser rangefinder sensor can be quickly fixed to the top of the car using the mounting holes of the connecting plate and can be easily connected by wiring through the wiring holes. The entire installation and operation process of the detection equipment is optimized, greatly shortening the detection time, improving detection efficiency, reducing elevator maintenance costs and downtime, and improving overall operational efficiency.

[0050] 3. The design of the connection mechanism ensures that the magnetoelectric sensor does not shift or loosen during elevator operation. Components such as springs, sliders, clamps, and convex grooves in the connection mechanism work together to provide a secure connection while also offering elasticity and buffering capabilities. This effectively copes with vibrations and impacts during elevator operation, preventing damage to components that may result from rigid connections. The rational design and coordinated operation of each component enable the equipment to operate stably in complex elevator operating environments, extending its service life and further ensuring the continuous and accurate conduct of elevator testing, thus enhancing the safety and reliability of elevator operation.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
