Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an elevator component wear detection device. Background Technology

[0002] The traction sheave is a rope pulley on the traction machine. It transmits power to the elevator by utilizing the friction between the traction steel wire rope and the grooves on the sheave's rim. However, as the elevator operates over time and experiences uneven loads, the traction sheave will wear down. When the wear reaches a certain level, the traction sheave needs to be replaced to prevent elevator accidents. Therefore, it is necessary to inspect the wear condition of the traction sheave.

[0003] Currently, the wear detection of traction sheaves requires stopping the machine for inspection, and it is not possible to conduct real-time detection directly during the operation of the traction sheaves. This not only increases the complexity of the inspection work and affects the operation of the elevator, but also increases the difficulty of the inspection work. Therefore, a wear detection device for elevator components is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figures 1-4 The elevator component wear detection device shown includes a detection box 100. A detection needle 101 is movably mounted on the top of the detection box 100, and the bottom of the detection needle 101 extends into the inner cavity of the detection box 100. A pressure sensor 102 is fixedly installed at the bottom of the inner cavity of the detection box 100. The bottom end of the detection needle 101 is movably attached to the top end of the pressure sensor 102. An elastic support assembly is disposed between the detection needle 101 and the pressure sensor 102, and the elastic support assembly is used to provide an elastic thrust for the upward movement of the detection needle 101. The detection box 100 is positioned directly below the traction sheave and fixed to the traction machine frame. During installation, the top of the detection needle 101 needs to contact the rope groove on the traction sheave. Because the elastic support assembly provides upward elastic support to the detection needle 101, the top of the detection needle 101 always rests against the rope groove of the traction sheave. As the rope grooves of the traction sheave wear down and their diameter decreases or becomes concave, the detection needle 101 will move upward using the thrust provided by the elastic support component. This allows the detection needle 101 to move up and down as the diameter of the inner wall of the rope groove on the traction sheave changes. During the up-and-down movement of the detection needle 101, different pressures are provided to the pressure sensor 102 through the elastic support component. The pressure sensor 102 can detect the location and degree of wear in the rope groove on the traction sheave based on the changes in the monitored pressure. This eliminates the need to stop the traction sheave for inspection. Furthermore, the detection box 100 can be equipped with a corresponding number of detection needles 101 and pressure sensors 102 according to the number of rope grooves on the traction sheave, thus satisfying the requirement to detect the wear degree of rope grooves at different locations on the same traction sheave, making the inspection work more convenient and efficient.

[0028] In addition, a controller 106, which can be replaced by a microcontroller, is fixedly installed on the side wall of the inner cavity of the detection box 100. The controller 106 is coupled to the pressure sensor 102. The controller 106 receives and processes the pressure signal monitored by the pressure sensor 102, and can transmit the detection information to an external display terminal for the user to view and understand.

[0029] The elastic support assembly includes a support ring 103, which is positioned directly below the detection needle 101 and abuts against the top of the pressure sensor 102. A blocking ring 105 is fixedly connected to the top of the support ring 103. The bottom end of the detection needle 101 has a telescopic groove that slides with the blocking ring 105. An elastic spring 104 is sleeved around the blocking ring 105, and both ends of the elastic spring 104 are fixedly connected to the opposite sides of the support ring 103 and the detection needle 101, respectively. Because the detection needle 101... The pressure on the detection needle 101 is transmitted to the elastic spring 104 by the squeezing action inside the rope groove at the bottom of the traction sheave. The elastic spring 104 then transmits the pressure to the pressure sensor 102 through the support ring 103. This allows the compression of the elastic spring 104 to be changed during the up-and-down movement of the detection needle 101, thereby indicating the position and amplitude of the up-and-down movement of the detection needle 101 through the magnitude of the pressure. This allows the user to understand the location and degree of wear on the inner wall of the rope groove on the traction sheave.

[0030] In other embodiments, the top of the detection needle 101 is provided with a sliding component, and the top of the detection needle 101 contacts the inner wall of the traction groove of the traction sheave through the sliding component; wherein, the sliding component includes a mounting slot 108, which is opened on the top of the detection box 100, and an auxiliary wheel 107 is rotatably mounted inside the mounting slot 108, with the top of the auxiliary wheel 107 extending to the position above the detection box 100, and the outer wall of the auxiliary wheel 107 is provided with a wear-resistant wheel sleeve; by providing a mounting slot 108 on the top of the detection needle 101 for the rotatable mounting of the auxiliary wheel 107, when the auxiliary wheel 107 is in contact with the traction sheave, the rotation of the traction sheave drives the auxiliary wheel 107 to rotate, reducing the frictional resistance between the two, and at the same time reducing the wear and tear between the two, improving the safety of the detection process.

[0031] Furthermore, the top of the detection box 100 is provided with a mounting groove that communicates with the mounting slot 108. The detection box 100 is fixedly mounted with a laser ranging mechanism 109 through the mounting groove. The laser ranging mechanism 109 is used to monitor the change in distance from the outer wall of the auxiliary wheel 107 to the bottom of the mounting slot 108. By using the laser ranging mechanism 109 mounted on the detection needle 101 to monitor the distance from the outer wall of the auxiliary wheel 107 to the bottom of the mounting slot 108, the error caused by the wear of the auxiliary wheel 107 to the wear detection result can be eliminated.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
