[0002] The brake is an important component to ensure the safe and normal operation of the elevator. Under normal circumstances, after the elevator traction machine host stops rotating, the static state of the car depends on the brake to maintain. During the operation of the elevator, if a sudden power outage or the sudden disconnection of the electrical safety device occurs, the reduction and stop of the elevator speed completely depend on the function of the brake. The elevator braking detection device is a device that can detect whether the braking ability of the elevator is qualified.

[0003] The application number is CN202222193850.0, which discloses an elevator braking detection device, including a housing. A groove is opened on the outer edge of the housing, a circular groove is opened on the inner wall of the groove, a motor is fixedly assembled on the inner wall of the circular groove, a rotating rod is fixedly assembled on the outer edge of the output shaft of the motor, a connecting plate is rotatably sleeved on the outer edge of the rotating rod, and a first square groove is opened on the outer edge of the connecting plate. Through the cooperation of the pulley and the velocity sensor, it is beneficial to detect the elevator brake, which is beneficial to ensuring the normal use of the elevator and reducing the occurrence of elevator accidents. Through the cooperation of the threaded rod and the gear teeth, it is beneficial to fix the detection device, so that the device can effectively perform operations.

[0004] Although such a setting can detect the elevator through the cooperation of the pulley and the velocity sensor, when the elevator is running, the steel wire rope will vibrate, which is likely to cause the pulley to disengage from the steel wire rope, resulting in inaccurate detection. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides an elevator braking detection device.

[0006] The utility model is realized by the following technical solutions: An elevator braking detection device includes a tester.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In the present utility model, by rotating the rotating rod, the rotating rod drives the second threaded rod to rotate. When the second threaded rod rotates, the length of the second threaded rod outside the threaded tube changes. The second threaded rod drives the pushing and adjusting tube to move, the adjusting tube drives the fixing rod to move, and the fixing rod drives the roller to move, so that the steel wire rope contacts the roller and is located in the groove of the roller. Continuing to rotate the rotating rod, although one end of the roller is blocked by the steel wire rope, the second threaded rod still pushes the adjusting tube towards the steel wire rope, so that the fixing rod pushes the anti-detachment plate to compress the spring. At this time, the spring applies a force to the fixing rod towards the steel wire rope, which can still make the roller firmly fit on the steel wire rope when the steel wire rope vibrates, so as to ensure the accuracy of detection.

[0017] In the present utility model, by rotating the knob, the knob drives the first threaded rod to rotate. When the first threaded rod rotates, the slider threadedly connected to the first threaded rod moves along the first threaded rod, the threaded tube on the first threaded rod moves, the threaded tube drives the second threaded rod to move, the second threaded rod drives the rotating rod adjusting tube to move, the adjusting tube drives the fixing rod to move, and the fixing rod drives the roller to move, so that the position of the roller can be adjusted, which is convenient for aligning the roller with the steel wire rope.

A slider 7 is threadedly connected to the outer wall of the first threaded rod 6. The bottom of the slider 7 contacts the side of the tester 1 close to the fixing frame 4. A knob 8 is fixedly connected to the right of the first threaded rod 6. The width of the fixing frame 4 is the same as the width of the tester 1. The chute 5 penetrates through the top of the fixing frame 4.

[0027] A threaded tube 9 is fixedly connected to the side of the slider 7 away from the tester 1. A second threaded rod 10 is threadedly connected inside the threaded tube 9. The second threaded rod 10 is sleeved inside the chute 5. One end of the second threaded rod 10 away from the threaded tube 9 is fixedly connected to a rotating rod 11. One end of the second threaded rod 10 away from the threaded tube 9 is rotatably connected to an adjusting tube 12. A spring 13 is fixedly connected to the bottom inside the adjusting tube 12. One end of the spring 13 away from the bottom inside the adjusting tube 12 is fixedly connected to an anti - detachment plate 14. The threaded tube 9 is located at the central axis of the slider 7. The height of the threaded tube 9 is lower than the height of the fixing frame 4. The diameter of the anti - detachment plate 14 is larger than the diameter of the top opening of the adjusting tube 12.

[0028] The outer wall of the anti - detachment plate 14 is slidably connected inside the adjusting tube 12. A fixing rod 15 is fixedly connected to the side of the anti - detachment plate 14 away from the adjusting tube 12. One end of the fixing rod 15 away from the adjusting tube 12 is rotatably connected to a roller 16. A vector sensor 17 is fixedly connected to one end of the fixing rod 15 away from the adjusting tube 12. A mounting plate 18 is fixedly connected to the side of the tester 1 away from the fixing frame 4. Mounting holes 19 are provided on the mounting plate 18.

The mounting holes 19 are symmetrically arranged with the center of the mounting plate 18 as the center.

[0029] The implementation principle of an elevator braking detection device in an embodiment of the present application is as follows: The device is fixed to the elevator shaft through the mounting holes 19 on the mounting plate 18. Then, rotate the knob 8, and the knob 8 drives the first threaded rod 6 to rotate. When the first threaded rod 6 rotates, the slider 7 threadedly connected to the first threaded rod 6 moves along the first threaded rod 6, and the threaded tube 9 on the first threaded rod 6 moves. The threaded tube 9 drives the second threaded rod 10 to move, the second threaded rod 10 drives the rotating rod adjusting tube 12 to move, the adjusting tube 12 drives the fixed rod 15 to move, and the fixed rod 15 drives the roller 16 to move, so that the position of the roller 16 can be adjusted to facilitate aligning the roller 16 with the steel wire rope.

The second threaded rod 10 drives the push adjusting tube 12 to move, the adjusting tube 12 drives the fixed rod 15 to move, and the fixed rod 15 drives the roller 16 to move, so that the steel wire rope contacts the roller 16 and is located in the groove of the roller 16. Continue to rotate the rotating rod 11. Although one end of the roller 16 is blocked by the steel wire rope, the second threaded rod 10 still pushes the adjusting tube 12 towards the steel wire rope, so that the fixed rod 15 pushes the anti - detachment plate 14 to compress the spring. At this time, the spring will apply a force to the fixed rod 15 to move it closer to the steel wire rope, which can still keep the roller 16 firmly attached to the steel wire rope when the steel wire rope vibrates, so as to ensure the accuracy of detection.
