Description

Technical Field

[0001] This utility model relates to the field of traction sheave wear detection technology, specifically a traction sheave wear detection device. Background Technology

[0002] The traction sheave is a key component mounted on the main shaft of the traction machine, and it is connected to the elevator car and counterweight via traction steel wire ropes. When the traction machine rotates, the traction sheave drives the steel wire ropes with the help of friction, causing the car and counterweight to move up and down within the hoistway.

[0003] In the current traction sheave system, the wear of the traction sheave and its groove is mostly detected manually, which is inefficient and not very accurate. This method of detection makes the results not readily apparent and the detection effect is poor. Once a detection error occurs, it can easily lead to elevator malfunctions, seriously affecting the safety of elevator use and even endangering the personal safety of users. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a traction sheave wear detection device, which can improve the detection accuracy and avoid safety accidents.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a traction wheel wear detection device, comprising a base plate, a turntable platform mounted on the base plate, the traction wheel body placed at the center point of the turntable platform, a support block fixedly connected to the base plate, a sliding groove provided on the support block, a lifting mechanism mounted on the support block, a slider threadedly connected to the lifting mechanism, and a high-precision laser probe mounted on the slider.

[0006] Furthermore, a multi-stage electric telescopic rod is installed between the slider and the high-precision laser probe.

[0007] Furthermore, the lifting mechanism includes a driver fixedly connected to the support block, a threaded rod fixedly connected to the output end of the driver, two slide rods fixedly connected to the inner wall of the slide groove, a slider threadedly connected to the threaded rod, and the slider slidably connected to the two slide rods.

[0008] Furthermore, a placement plate is fixedly connected to the turntable platform. A groove is formed on the placement plate, and a clamping assembly is installed in the groove. Several rolling assemblies are fixedly connected to the surface of the placement plate. The clamping assembly includes two sliding rods two fixedly connected to the inner wall of the groove. A bidirectional threaded rod two is rotatably connected to the inner wall of the groove. A knob is fixedly connected to both ends of the bidirectional threaded rod two. Two sliding plates are threadedly connected to the bidirectional threaded rod two. The two sliding plates are slidably connected to the two sliding rods two. A sliding cavity is formed at both ends of the upper surface of the two sliding plates. A threaded hole is formed on the bottom wall of the sliding cavity. A threaded rod three is threadedly connected to the threaded hole. A limit post is fixedly connected to the upper surface of the threaded rod three. The limit post is slidably connected to the sliding cavity. A slot is formed on the knob. A Z-shaped crank handle matching the slot is placed on the bottom plate.

[0009] Furthermore, the rolling assembly includes a rolling seat fixedly connected to the placement plate, on which rollable balls are mounted.

[0010] Furthermore, a number of self-locking casters are installed on the lower surface of the base plate, and a tie rod is fixedly connected to the upper surface of the base plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This traction sheave wear detection device can flexibly adapt to traction sheaves of different sizes and specifications for wear detection, effectively solving the limitation of traditional detection equipment that can only target equipment of a single size. It uses a high-precision laser probe for detection without contacting the grooves of the traction sheave, thus effectively avoiding secondary damage to the grooves of the traction sheave during the detection process. It is simple and efficient to operate, greatly improving the convenience and reliability of the detection. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 4 A base plate 1, on which a turntable platform 2 is installed, and a traction wheel body 27 is placed at the center point of the turntable platform 2. A support block 3 is fixedly connected to the base plate 1. A sliding groove 4 is opened on the support block 3. A lifting mechanism is installed on the support block 3. A slider 5 is threadedly connected to the lifting mechanism. A high-precision laser probe 6 is installed on the slider 5.

[0020] like Figures 1 to 4 As shown, in use, the traction sheave wear detection device of this utility model places the traction sheave body 27 in the middle position on the turntable platform 2. The position of the center point of the uppermost groove of the traction sheave body 27 is determined by measuring the distance between the upper and lower sides of the groove and the turntable platform 2. This allows the high-precision laser probe 6 to be adjusted to be positioned in the middle of the uppermost groove of the traction sheave body 27. The high-precision laser probe 6 is connected to an external processing device with display function (such as a Micro-Epsilon ILD2300 display controller). The processing device is connected to a controller (such as a DAM-T2222-MT industrial-grade data acquisition controller). The controller is connected to the driver 7. The high-precision laser probe 6 is aligned with the center point of the turntable platform 2. The vertical position of the high-precision laser probe 6 is adjusted by the lifting mechanism so that the ranging point is located in the groove of the traction wheel body 27. The high-precision laser probe 6 emits a laser beam and measures the time from emission to reflection and return from the target. Combined with the speed of light (approximately 299,792,458 m / s), the target distance is calculated. The turntable platform 2 rotates slowly or at a fixed rotation angle to determine the distance between the laser emission point of the high-precision laser probe 6 and any point in the groove of the traction wheel body 27. This is used to determine whether the groove of the traction wheel body 27 is worn.

[0021] like Figure 1 As shown, a multi-stage electric telescopic rod 19 is installed between the slider 5 and the high-precision laser probe 6.

[0022] Specifically, the dimensions of the traction wheel body 27 are different. The distance between the laser emission point of the high-precision laser probe 6 and the groove of the traction wheel body 27 can be adjusted by the multi-stage electric telescopic rod 19 (30 to 50 mm is better for measurement accuracy), thereby improving the measurement accuracy.

[0023] like Figure 1 and Figure 2 As shown, the lifting mechanism includes a driver 7 fixedly connected to the support block 3, a threaded rod 8 fixedly connected to the output end of the driver 7, two slide rods 9 fixedly connected to the inner wall of the slide groove 4, a slider 5 threadedly connected to the threaded rod 8, and the slider 5 slidably connected to the two slide rods 9.

[0024] Specifically, the threaded rod 8 is rotatably connected to the inner wall of the slide groove 4 via a bearing. A controller can be installed on the base plate 1 to control the driver 7, thereby driving the threaded rod 8 to rotate, so that the slider 5 moves along the direction of the slide groove 4, thereby adjusting the position of the high-precision laser probe 6, so that the high-precision laser probe 6 can detect each groove of the traction wheel body 27.

[0025] like Figure 3 and Figure 4 As shown, a placement plate 10 is fixedly connected to the turntable platform 2. A groove 11 is provided on the placement plate 10. A clamping assembly is installed in the groove 11. Several rolling assemblies are fixedly connected to the surface of the placement plate 10. The clamping assembly includes two sliding rods 12 fixedly connected to the inner wall of the groove 11. A two-way threaded rod 13 is rotatably connected to the inner wall of the groove 11. A knob 14 is fixedly connected to both ends of the two-way threaded rod 13. Two sliding plates 15 are threadedly connected to the two sliding rods 12. A sliding cavity 22 is provided at both ends of the upper surface of the two sliding plates 15. A threaded hole 23 is provided on the bottom wall of the sliding cavity 22. A threaded rod 24 is threadedly connected to the threaded hole 23. A limit post 16 is fixedly connected to the upper surface of the threaded rod 24. The limit post 16 is slidably connected to the sliding cavity 22. A slot 20 is provided on the knob 14. A Z-shaped crank handle 21 matching the slot 20 is placed on the base plate 1.

[0026] Specifically, the bidirectional threaded rod 13 is rotatably connected to the inner wall of the groove 11 via a bearing, placing the traction wheel body 27 on the upper surface of the placement plate 10. The height of the limiting post 16 can be adjusted by rotating it according to the height of the lowest groove of the traction wheel body 27. The Z-shaped handle 21 is connected to the slot 20 on the knob 14. Shaking the Z-shaped handle 21 rotates the knob 14, causing the bidirectional threaded rod 13 to rotate. This drives the two sliding plates 15 to move in opposite directions toward the surface of the traction wheel body 27 until all four limiting posts 16 are in contact with the surface of the traction wheel body 27. Combined with manual adjustment, the circumference of the traction wheel body 27 is squeezed to quickly fix the traction wheel body 27 at the center point of the turntable platform 2. During this process, the rolling component can reduce the friction between the traction wheel body 27 and the placement plate 10, thus facilitating the adjustment of the position of the traction wheel body 27.

[0027] like Figure 4 As shown, the rolling assembly includes a rolling seat 25 fixedly connected to the placement plate 10, and a rolling ball 26 is mounted on the rolling seat 25.

[0028] Specifically, since the traction wheel body 27 is relatively heavy, it is placed on multiple balls 26. Since the balls 26 can roll on the rolling seat 25, it is convenient for the traction wheel body 27 to move on the balls 26.

[0029] like Figure 1 As shown, a number of self-locking casters 17 are installed on the lower surface of the base plate 1, and a pull rod 18 is fixedly connected to the upper surface of the base plate 1.

[0030] Specifically, the self-locking casters 17 and the pull rod 18 facilitate the movement of the base plate 1, thereby enabling the device to be moved quickly and transferred to other locations.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
