Description

Technical Field

[0001] This utility model belongs to the field of elevator safety technology, specifically relating to an elevator restraint device action verification device. Background Technology

[0002] The elevator speed limiter (commonly known as the elevator speed governor) is a key safety control component in the elevator safety protection system. Its function is to ensure the safety of the elevator during operation. When the elevator car overspeeds or even falls due to any reason, and all other safety protection devices fail to function, the speed governor and safety brake will work together to stop the elevator car.

[0003] The existing technology includes a novel elevator speed governor testing device with patent publication number CN214935096U. In this device, a rubber friction wheel presses against the speed governor rope wheel, and a servo motor controls the rubber friction wheel to slowly accelerate, thereby accelerating the speed governor rope wheel. Reflective paper is attached to the speed governor rope wheel; a photoelectric encoder records the angular acceleration of the speed governor rope wheel each time the reflective paper reaches its highest point. Vibration occurs between the speed governor rope wheel and the rubber friction wheel during rotation, and a spring above the servo motor dampens this vibration. Using a photoelectric encoder for speed detection offers high efficiency and accuracy, and can meet the speed governor requirements of ultra-high-speed elevators. However, in practical use, the following shortcomings remain: From a practical standpoint, this device cannot test speed governors of different elevator models, affecting its usability and reducing its application range.

[0004] Therefore, there is a need for an elevator speed limiter action verification device to solve the problem that the existing technology cannot detect different models of elevator speed limiters, which reduces the scope of application of the device. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an elevator clamp action verification device, comprising a base plate, a mounting mechanism, a clamp body, and a verification mechanism. The base plate has an internal mounting cavity, the mounting mechanism is located inside and above the mounting cavity, the clamp body is located above the mounting mechanism, and the verification mechanism is located outside the clamp body.

[0007] The installation mechanism consists of a double-acting lead screw, a handle, a threaded block, a fixed rod, a connecting plate, a threaded rod, and a pressure plate. The double-acting lead screw is rotatably connected to the inside of the mounting cavity of the base plate, the handle is fixedly connected to the right end of the double-acting lead screw, and the threaded block is symmetrically threaded to the outside of the double-acting lead screw.

[0010] Furthermore, it should be noted that the verification mechanism consists of a fixed frame, a cylinder, a sliding block, a motor, a connecting shaft, a drive wheel, a speed sensor, a position sensor, a transmission line, and a controller.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4 This utility model provides an elevator clamp action verification device, including a base plate 1, a mounting mechanism 2, a clamp body 3 and a verification mechanism 4. The base plate 1 has an internal mounting cavity, the mounting mechanism 2 is located inside and above the mounting cavity, the clamp body 3 is located above the mounting mechanism 2, and the verification mechanism 4 is located outside the clamp body 3.

[0024] The mounting mechanism 2 consists of a two-way lead screw 201, a handle 202, a threaded block 203, a fixing rod 204, a connecting plate 205, a threaded rod 206, and a pressure plate 207. The two-way lead screw 201 is rotatably connected to the inside of the mounting cavity of the base plate 1. The handle 202 is fixedly connected to the right end of the two-way lead screw 201. The threaded block 203 is symmetrically threaded to the outside of the two-way lead screw 201.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the fixing rod 204 is fixedly connected to the inside of the mounting cavity, the threaded block 203 is slidably connected to the outside of the fixing rod 204, the connecting plate 205 is fixedly connected to the top of the threaded block 203, and a through groove is provided on the top surface of the mounting cavity, with the connecting plate 205 slidably connected to the inside of the through groove.

[0026] By sliding the threaded block 203 outside the fixed rod 204, the rotation of the threaded block 203 is restricted, preventing the threaded block 203 from rotating with the bidirectional lead screw 201 and ensuring that the threaded block 203 can move stably in a straight line.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the threaded rod 206 is threadedly connected to both sides of the top plate of the connecting plate 205, and a rotating disk is fixedly connected to the top of the threaded rod 206, while the pressure plate 207 is rotatably connected to the bottom of the threaded rod 206.

[0028] The rotating disc facilitates the rotation of the threaded rod 206, improving the practicality of the mechanism.

[0029] According to the above working process, the installation mechanism 2 can be used to move the two connecting plates 205 by rotating the handle 202 to clamp the clamping device body 3 of different sizes. Then, by rotating the threaded rod 206, the pressure plate 207 is moved down to press and fix the clamping device body 3 again, ensuring the stability of the clamping device body 3 during the re-verification process and improving the applicability of the device.

[0030] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the verification mechanism 4 consists of a fixed frame 401, a cylinder 402, a sliding block 403, a motor 404, a connecting shaft 405, a drive wheel 406, a speed sensor 407, a position sensor 408, a transmission line 409, and a controller 410. The fixed frame 401 is fixedly connected to the upper rear side of the base plate 1. The cylinder 402 is fixedly connected to the top surface of the fixed frame 401, and the output end of the cylinder 402 extends into the interior of the fixed frame 401. The sliding block 403 is fixedly connected to the output end of the cylinder 402, and the sliding block 403 is slidably connected to the interior of the fixed frame 401.

[0031] Further as Figure 1 , Figure 2 and Figure 4As shown, it is worth noting that the motor 404 is fixedly connected to the back of the sliding block 403, the connecting shaft 405 passes through the front and rear sides of the sliding block 403, and the rear end of the connecting shaft 405 is connected to the output end of the motor 404. The drive wheel 406 is fixedly connected to the front end of the connecting shaft 405.

[0032] The rotation of the drive wheel 406 drives the rope wheel to rotate, which can simulate the upward or downward speed of the elevator car, making it easier to verify the restraint device body 3.

[0033] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the speed sensor 407 and the position sensor 408 are respectively connected to the front end of the sliding block 403 and are symmetrically arranged on both sides of the rope wheel of the limiter body 3. One end of the transmission line 409 is fixedly connected to one side of the motor 404, and the controller 410 is fixedly connected to the other end of the transmission line 409. The cylinder 402, the motor 404, the speed sensor 407, and the position sensor 408 are respectively electrically connected to the controller 410.

[0034] The rotational speed and position of the rope wheel are monitored in real time by the set speed sensor 407 and position sensor 408, and the data is transmitted to the controller 410 to judge the accuracy and reliability of the action of the restraint body 3.

[0035] This solution has the following working process: In use, first place the clamp limiter body 3 on the upper front side of the base plate 1. Rotate the handle 202 to drive the bidirectional lead screw 201 to rotate. The threaded block 203 slides outside the fixed rod 204, restricting the rotation of the threaded block 203 and preventing it from rotating with the bidirectional lead screw 201. This ensures the threaded block 203 moves stably in a straight line, causing the upper connecting plate 205 to move towards each other until the connecting plate 205 clamps both ends of the clamp limiter body 3. Then, rotate the threaded rod 206 to move the pressure plate 207 downwards, pressing and fixing the clamp limiter body 3 again, ensuring the stability of the clamp limiter body 3 during verification. Then, through… The cylinder 402 drives the sliding block 403 to move downward, adjusting the height of the drive wheel 406, speed sensor 407, and position sensor 408, so that the drive wheel 406 is in close contact with the rope wheel of the limiter body 3. At the same time, the speed sensor 407 and position sensor 408 are located on both sides of the rope wheel. The motor 404 drives the connecting shaft 405 to rotate, and the rotation of the drive wheel 406 drives the rope wheel of the limiter body 3 to rotate, simulating the upward or downward speed of the elevator car. The speed sensor 407 and position sensor 408 monitor the rotation speed and position of the rope wheel in real time, and transmit the data to the controller 410 to judge the accuracy and reliability of the operation of the limiter body 3.

[0036] In summary: The installation mechanism 2 allows for the movement of two connecting plates 205 by rotating the handle 202, clamping different sized limiter bodies 3. Rotating the threaded rod 206 then moves the pressure plate 207 downwards, further tightening and fixing the limiter body 3, ensuring its stability during verification and improving the device's applicability. The verification mechanism 4 allows for the adjustment of the height of the drive wheel 406, speed sensor 407, and position sensor 408 to accommodate limiter bodies 3 of different heights. The motor 404 drives the drive wheel 406, causing the rope wheel of the limiter body 3 to rotate, simulating the upward or downward speed of an elevator car. The speed sensor 407 and position sensor 408 monitor the rotation speed and position of the rope wheel in real time, transmitting the data to the controller 410 to determine the accuracy and reliability of the limiter body 3's operation.
