Description

Technical Field

[0001] This utility model relates to the field of elevator testing equipment technology, and in particular to a device for detecting traction sheave runout. Background Technology

[0002] The elevator traction sheave is a crucial component of an elevator, primarily responsible for transmitting the power of the traction machine. The friction between the wire rope and the rope groove is what lifts the car up and down; therefore, the rope groove of the traction sheave requires high precision during manufacturing. Inadequate groove runout can cause elevator vibration and accelerated wear, potentially leading to accidents.

[0003] In existing technologies, some detection methods rely on human experience, with staff directly observing the operation of the traction sheave and judging the runout by touch or simple tools. This method is prone to different judgments due to differences in the experience of the inspectors, and the detection process is complex and inefficient. Some simple detection devices can only measure a single point or a few points when the traction sheave is stationary, and cannot simulate the dynamic situation during actual operation. They cannot fully reflect the runout of the traction sheave at various positions when it is rotating at high speed, so improvements are needed. Utility Model Content

[0004] The purpose of this invention is to solve the problems of complex detection process, low efficiency and lack of multi-dimensional flexible adjustment of measurement position in the existing technology, which leads to incomplete and inaccurate measurement.

This achieves quick installation and disassembly of dial indicator A and dial indicator B without the need for tools, thus facilitating the replacement and maintenance of the dial indicator and ensuring the normal operation and detection accuracy of the testing device.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4As shown, this utility model provides a technical solution: a device for detecting traction sheave runout, comprising a base 1 and a placement platform 2. A turntable 3 is rotatably connected inside the placement platform 2. A spindle 4 is fixedly mounted on the upper surface of the turntable 3.

The surface of the device is fixedly mounted with upright plates A11 and B12. A mounting plate A13 is slidably connected to the side of upright plate A11.

A threaded rod 22 is rotatably connected inside mounting plate A13. A moving block A19 is fixedly mounted on the side of the device. The device is equipped with a motor B23. A movable block B24 is fixedly connected to the side of the mounting plate B16. An electric telescopic rod B25 is fixedly installed on the surface of the upright plate B12. The rotating rod 7 is rotatably connected to the placement platform 2. Gear A9 and gear B10 mesh and drive each other. The movable block A19 is slidably connected to the upright plate A11. The output end of the electric telescopic rod A20 is fixedly connected to the surface of the movable block A19. The output end of the motor B23 is fixedly connected to one end of the threaded rod 22. The threaded rod 22 is threadedly connected to the sliding block 21. The sliding block 21 is slidably connected to the mounting plate A13. The movable block B24 is slidably connected to the upright plate B12. The output end of the electric telescopic rod B25 is fixedly connected to the surface of the movable block B24.

[0023] In this embodiment, the motor A8 is started to drive the gear A9 to rotate, which in turn drives the rotating rod 7 to rotate the turntable 3, thereby driving the spindle 4 and the traction sheave mounted on it to rotate, simulating the actual operating state of the traction sheave. At the same time, the electric telescopic rod A20 is started to adjust the height of the mounting plate A13, and the electric telescopic rod B25 is started to adjust the height of the mounting plate B16. The drive motor B23 drives the threaded rod 22 to rotate, causing the sliding block 21, which is threadedly connected to the threaded rod 22, to slide along the mounting plate A13, thereby adjusting the position of the U-shaped plate A14. This allows for flexible adjustment of the positions of the dial indicators A15 and B18, enabling accurate measurement of the axial and radial runout of the traction sheave, achieving comprehensive detection of the traction sheave runout.

[0024] Example 2: As Figures 1-4As shown, dial indicator A15 and dial indicator B18 have insert blocks 26 on their sides, U-shaped plates A14 and B17 have slots 27 on their sides, and fixed plates 28 are fixedly installed on the sides of U-shaped plates A14 and B17.

The insert block 26 is slidably connected to the slot 27, and the limit rod 29 is slidably connected to the limit hole 30. One end of the tension spring 32 is fixedly connected to the side of the limit plate 31.

[0025] In this embodiment, by setting insert blocks 26 on the sides of dial indicators A15 and B18, and slots 27 on the sides of U-shaped plates A14 and B17, and utilizing a limiting structure composed of a fixing plate 28, a limiting rod 29, a limiting disc 31, and a tension spring 32, when the insert block 26 is inserted into the slot 27, the insert block 26 will squeeze the limiting rod 29 to move backward, and at the same time the tension spring 32 will be compressed. When the insert block 26 is inserted to a certain position, the limiting rod 29 will automatically insert into the limiting hole 30 under the action of the tension spring 32, thereby fixing dial indicator A15 or dial indicator B18. This achieves quick installation and removal of dial indicators A15 and B18 without the need for tools, thus facilitating the replacement and maintenance of the dial indicators and ensuring the normal operation and detection accuracy of the testing device.

[0026] The working principle of this embodiment is as follows: When the traction sheave runout detection device is working, motor A8 is first started. Motor A8 drives gear A9 to rotate. Since gear A9 meshes with gear B10 and the rotating rod 7 is rotatably connected to the placement platform 2, the rotation of gear A9 will cause the rotating rod 7 to drive the turntable 3 to rotate, which in turn drives the spindle 4 to rotate. The traction sheave mounted on the spindle 4 also rotates accordingly, simulating the actual operating state of the traction sheave. Then, according to the detection requirements, the electric telescopic rod A20 is started to adjust the height of the mounting plate A13, and the electric telescopic rod B25 is started to adjust the height of the mounting plate B16. At the same time, the motor B23 drives the threaded rod 22 to rotate. The threaded rod 22 is threadedly connected to the sliding block 21, and the sliding block 21 is slidably connected to the mounting plate A13. Under the drive of motor B23, the sliding block 21 slides along the mounting plate A13, thereby... Adjusting the position of U-shaped plate A14 allows for flexible adjustment of the positions of dial indicators A15 and B18, enabling them to accurately measure the axial and radial runout of the traction wheel. When installing dial indicators A15 and B18, insert block 26 into the slots 27 on the sides of U-shaped plates A14 and B17. During insertion, block 26 presses against the limiting rod 29, causing it to move backward and compressing the tension spring 32. When block 26 is inserted to a certain position, the limiting rod 29 automatically inserts into the limiting hole 30 on the side of block 26 under the action of the tension spring 32, thus fixing dial indicators A15 and B18 and achieving quick installation. Disassembly is performed in reverse. This installation and disassembly method requires no tools, facilitating dial indicator replacement and maintenance, and ensuring the normal operation and accuracy of the testing device.
