The traction system mainly consists of a traction machine, traction steel ropes, a guide wheel, and a deflector sheave. The traction steel ropes will be worn after long-term use, so it is necessary to detect them frequently to avoid breakage and accidents. The existing steel rope wear monitoring usually stops the elevator every once in a while, and the wear of the steel ropes is monitored in the elevator machine room. The monitoring equipment is large in volume and requires the cooperation of multiple people to monitor the wear of the steel ropes one by one, resulting in low monitoring efficiency.

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides an elevator traction steel wire rope wear degree monitoring device, including a mounting box 1. A second ultrasonic flaw detector 4 for monitoring the wear of the steel wire rope is fixedly installed on the inner side wall of the mounting box 1. A connecting mechanism 2 for disassembly and assembly detection is further provided on the surface of the mounting box 1. The mounting plate 21 in the connecting mechanism 2 is fixedly installed at the outer end of the mounting box 1;

[0024] The connecting mechanism 2 further includes a baffle 27. A first ultrasonic flaw detector 29 is bolted through the outer side of the baffle 27. A clamping component is arranged at the outer end of the mounting box 1. The baffle 27 is installed on the surface of the mounting box 1 through the clamping component.

[0025] It is beneficial for it to carry out bidirectional alternating monitoring, and at the same time, it can be conveniently disassembled to improve the monitoring effect and disassembly and assembly efficiency.

[0026] Preferably, the clamping component includes a support module and an insertion module. The support module is arranged on the outer side of the mounting box 1, and the insertion module is arranged on the outer side of the support module.

[0027] Such as Figure 4As shown, the spring 22 in the support module is welded on the mounting plate 21, and a circular plate 23 is welded on the end of the spring 22. A connecting rod 24 is fixedly installed on one side of the circular plate 23. The spring 22 is located on the outside of the connecting rod 24. The mounting plate 21 and the connecting rod 24 are connected in a through-type sliding manner, which is convenient for elastic pushing and pulling, and can also provide support for lateral sliding.

[0028] like Figure 4 As shown, the connecting plate 25 in the insertion module is rotatably connected to the end of the connecting rod 24 away from the circular plate 23, and an insertion rod 26 is fixedly installed on one side of the connecting plate 25. The surface of the installation box 1 and the surface of the baffle 27 are both provided with a socket 28, and the connecting rod 24 is inserted into the inside of the socket 28, which is conducive to the effect of plug-in clamping and fixing under the action of the elastic pulling reset force of the platform, so as to facilitate its disassembly and assembly operations.

[0029] When monitoring:

[0030] The second ultrasonic flaw detector 4 and the first ultrasonic flaw detector 29 are started in an indirect alternating manner. Since they are located in the elevator shaft, the traction wire rope will pass through the second ultrasonic flaw detector 4 and the first ultrasonic flaw detector 29 when the traction system is in operation. When the elevator is ascending, the first ultrasonic flaw detector 29 is used for ultrasonic flaw detection. On the contrary, when the elevator is descending, the second ultrasonic flaw detector 4 is used for flaw detection. The cooperation between the two can improve the effect of wear degree flaw detection.

[0031] The picture shows the installation status:

[0032] When disassembling, simply pull the connecting plate 25 outward to drive the connecting rod 24 to pull the circular plate 23. At this time, the circular plate 23 will squeeze the spring 22, and then the insertion rod 26 will be disengaged from the inside of the socket 28 to complete the cancellation of the insertion fixed state. Then, the connecting plate 25 is rotated to drive the insertion rod 26 to rotate in the opposite direction to remove the baffle 27 and the first ultrasonic flaw detector 29, so as to facilitate the disassembly and maintenance and replacement between the first ultrasonic flaw detector 29 and the second ultrasonic flaw detector 4.

[0033] Furthermore, a cleaning mechanism 3 is provided at the top and the bottom of the installation box 1. The cleaning mechanism 3 includes an adapting component and a processing component. The adapting component is provided at the top of the installation box 1, and the processing component is provided at the inner side of the adapting component.

[0034] like Figure 2 and 3 As shown, the limit plate 31 in the adapter assembly is fixedly installed on the top and bottom of the installation box 1, and the top and bottom of the installation box 1 are provided with adapter holes 35. A screw 32 is placed through the inner side of the limit plate 31 to facilitate the adaptation of the wire rope and the installation of the brush plate 34.

[0035] like Figure 2As shown, the connecting block 33 in the processing component is fixedly installed at the inner end of the screw rod 32. A brush plate 34 is fixedly installed on the inner side of the connecting block 33. A bracket 5 is fixedly installed at the bottom of the installation box 1. The brush plate 34 can play a role in cleaning the steel wire rope.

[0036] As shown in the figure is the installation state:

[0037] When disassembly and replacement are required, directly loosen the nut on the screw rod 32 so that the nut does not press against the limit plate 31, and then directly pull up the two opposing brush plates 34 to complete the disassembly operation. When installing, just operate in the reverse of the above method.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
