Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator traction sheave groove wear detection device which is easy to adjust. Background Art

[0002] The traction sheave is a key component in an elevator, driving the elevator up and down through friction with the wire rope. Over time, the sheave grooves of the traction sheave gradually wear out, affecting the elevator's operating efficiency and safety.

[0003] After searching, the Chinese patent authorization number CN220011762U discloses an elevator traction sheave wear detection device. Although the detection device is easy to use and improves detection efficiency, the depth of the descent of the measuring column is read through the scale groove, thereby obtaining the depth of the wheel groove of the traction sheave body and the degree of wear of the wheel groove. However, the device for detecting traction sheave groove wear has certain limitations. The measuring columns of the measuring mechanism of the device cannot effectively adjust the spacing between the measuring columns according to the width and position of the wheel groove during the detection process.

[0004] This rigid structural design limits the adaptability and accuracy of the detection device, especially when facing traction wheels of different specifications, it is impossible to achieve accurate wear monitoring. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present invention provides an easily adjustable elevator traction sheave groove wear detection device, which solves the problem that the measuring mechanisms of the existing devices proposed in the background technology cannot adjust the spacing between the measuring mechanisms according to the width and position of the wheel groove.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] An easily adjustable elevator traction sheave groove wear detection device includes a housing, a sensor for detecting traction sheave groove wear is disposed in the housing, the sensor is connected to a circuit control module, and further includes:

[0008] The detection head at the end of the sensor extends out of the box;

[0009] A slider is arranged on the first guide shaft in the box body, and the sensor is installed on the slider;

[0010] The slot plate is located below the slider, and is provided with a guide slot. The bottom of each slider is movably arranged in the corresponding guide slot.

[0011] A second guide shaft, both ends of which are arranged on the box body, and the slot plate is slidably arranged on the second guide shaft;

[0012] The hand screw is rotatably arranged in the box body, and a knob is arranged at one end of the hand screw; the hand screw is connected to the slot plate through a thread.

[0013] The sensor of this solution can be a laser displacement sensor, an image sensor, or an electronic ruler, whichever can achieve the measurement effect.

[0014] As a further improvement of the above solution, there are five sliders, and the five sliders are arranged in a straight line with equal spacing between each other, so that the five sliders can synchronously drive the five detection heads to move horizontally.

[0015] As a further improvement of the above solution, two first guide shafts are provided and arranged parallel to each other. The outer wall of the first guide shaft is in sliding contact with the inside of the slider, and the first guide shaft can support the slider and limit the slider so that it can only move in the horizontal direction.

[0016] As a further improvement to the above solution, the bottom of the slider is provided with a protrusion, which slides within a guide groove. The spacing between the guide grooves decreases from one end to the other. This allows the multiple sliders to move synchronously, thereby ensuring that the measuring mechanisms of the device always maintain equal spacing during adjustment.

[0017] As a further improvement of the above solution, a threaded block is provided at one end of the slot plate, and a threaded hole is provided on the threaded block to be connected with a hand-tightened screw, and the position of the slot plate is adjusted by the hand-tightened screw.

[0018] The utility model provides an easily adjustable elevator traction sheave groove wear detection device, which has the following beneficial effects:

[0019] (1) When the device is in use, the detection head is aligned with the traction wheel groove, and the wear data of the wheel groove guide groove is collected by the detection head to perform wear detection. When the device detects different types of traction wheels, the hand screw is rotated to drive the external threaded block to move horizontally, and the threaded block can drive the slot plate to move horizontally. When the slot plate moves, the raised structure at the bottom of the slider moves in the hole groove on the slot plate surface. The raised structure at the bottom of the slider moves along the hole groove on the guide groove surface and the distance between them is adjusted. The measuring mechanism of the device can be aligned with the traction wheel groove by adjusting the distance between them, so that the detection device can be applied to the detection of various types of traction wheels.

[0020] (2) The device opens holes and grooves on the surface of the groove plate that are in a contracting structure with respect to each other, so that multiple sliders can keep moving synchronously when moving, thereby making the measuring mechanisms of the device always keep equal spacing with each other during the adjustment process, thereby facilitating the rapid alignment of the measuring mechanisms with the wheel grooves.

[0021] This solves the problem that the measuring mechanisms of the existing device cannot adjust the distance between the measuring mechanisms according to the width and position of the wheel groove. BRIEF DESCRIPTION OF THE DRAWINGS
