[0024] The utility model aims at the technical problem that it is difficult to detect and warn the wear degree of a pulley in real time in the prior art, and provides a cable hoist pulley wear detection device.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a cable hoist pulley wear detection device, which mainly includes: a pulley 1, a steel wire rope 7, a first mounting seat, a detection wheel 2, a mounting bracket 4, an angle sensor 11 and a tensioning mechanism 8. Among them: an annular groove 9 is arranged in the middle of the outer edge of the pulley 1, and the annular groove 9 is used to match the steel wire rope 7 and has a limiting effect on the steel wire rope 7. The pulley 1 is rotatably mounted on the inner side of the first mounting seat, the steel wire rope 7 matches the pulley 1, the steel wire rope 7 fits the annular groove 9 of the pulley 1, and the steel wire rope 7 is redirected by the pulley 1.

[0027] The outer diameter of the detection wheel 2 is smaller than the outer diameter of the pulley 1. The detection wheel 2 is rotatably mounted on the mounting bracket 4, and the mounting bracket 4 is connected to the first mounting seat. The outer edge of the detection wheel 2 fits with the outer edge of the pulley 1, and specifically, the detection wheel 2 fits with the annular groove 9 of the pulley 1.

[0028] One end of the tensioning mechanism 8 is connected to the upper end of the mounting bracket 4, and the other end of the tensioning mechanism 8 is connected to the first mounting seat. The tensioning mechanism 8 is used to maintain the tension of the detection wheel 2. During the tensioning process, the mounting bracket 4 can produce a certain deformation, tightening the detection wheel 2 so that it fits tightly against the outer edge of the pulley 1; the tensioning mechanism 8 can use a spring or a rubber belt.

[0029] The angle sensor 11 is installed on the first mounting seat, and the angle sensor 11 is used to connect and communicate with the electronic control device; the angle sensor 11 is used to detect the inclination angle of the mounting bracket 4, and upload the collected inclination angle value to the electronic control device. Under the action of the tensioning mechanism 8, the detection wheel 2 is always tightly fitted with the outer edge of the pulley 1. As the wear of the pulley 1 increases, the inclination angle of the mounting bracket 4 will gradually increase. Therefore, the inclination angle of the mounting bracket 4 can indirectly reflect the wear of the pulley 1.

[0030] Specifically, Figure 1 and Figure 2As shown, the first mounting seat includes: a clamp 5, a first guard plate 3 and a second guard plate 10. The clamp 5 is set as a "door" type structure.

The first guard plate 3 and the second guard plate 10 are arranged opposite to each other. The pulley 1 is rotatably mounted between the first guard plate 3 and the second guard plate 10 through a pin shaft.

[0031] like Figure 1 and Figure 2 As shown, in order to facilitate the installation of the angle sensor 11, the embodiment of the utility model is further provided with: a second mounting seat 6. The angle sensor 11 is mounted on the second mounting seat 6, and the second mounting seat 6 is fixed on the first mounting seat.

[0032] like Figure 1 and Figure 2 As shown, the working process of the cable crane pulley wear detection device provided by the embodiment of the utility model is: when the cable crane is working, the detection wheel 2 rolls inside the pulley 1 under the action of friction; if the pulley 1 is worn, under the action of the constant spring tension provided by the tensioning mechanism 8, the angle sensor 11 detects that the angle has changed, and when the detected angle is greater than 5 degrees, it needs to be replaced or repaired.

[0033] like Figure 1 and Figure 2 As shown, the cable pulley wear detection device provided by the embodiment of the utility model has at least the following beneficial effects or advantages:
