DETAILED DESCRIPTION

[0025] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0026] The utility model provides: a kind of steel wire rope loose rope alarm device, as shown in figure, including installation base plate 1, lifting shaft 4 and winding in the outer arc surface of lifting shaft 4 steel wire rope 5;Wherein, installation base plate 1 upper surface is provided with the lifting system 3 for driving lifting shaft 4 rotation, by lifting system 3 driving lifting shaft 4 rotation, to drive steel wire rope 5 to lift, lifting system 3 is the complex and precise system of lift mechanism, screw rod, bolt etc. Figures 1-3

[0027] As preferred, the end of steel wire rope 5 away from lifting shaft 4 is connected with grabber 6, and the upper surface of installation base plate 1 is provided with a loose rope alarm assembly 2 for detecting the tightness of steel wire rope 5. The loose rope alarm assembly 2 includes a mounting column 13, a lever module and a detection module. The mounting column 13 is arranged on the upper surface of the installation base plate 1 through a support plate, and the mounting column 13 is rotatably connected with the support plate. The steel wire rope 5 and the lever module are both located on one side of the installation base plate 1, and neither of them is in contact with the installation base plate 1. By arranging the mounting column 13 on the upper surface of the installation base plate 1 through the support plate, the mounting column 13 is extended outward, so that the lever module on the outer arc surface of the mounting column 13 can rotate without scratching the installation base plate 1, thereby ensuring the stability of the loose rope alarm assembly 2 during the overall operation.

[0028] Specifically, when the steel wire rope 5 is running normally, the steel wire rope 5 is in a state of being stretched and straightened. After the steel wire rope 5 is loosened, the steel wire rope 5 below the steel wire rope drum is no longer in a state of being stretched and straightened, and is tilted to the side. The loose rope alarm assembly 2 can determine whether the steel wire rope 5 is loosened by distinguishing the two different states of the steel wire rope 5.

[0029] Further, the lever module includes a first connecting column 8 and a second connecting column 10. The first connecting column 8 and the second connecting column 10 are both fixedly arranged on the outer arc surface of the mounting column 13. The first connecting column 8 is located on the side of the mounting column 13 close to the steel wire rope 5, and the second connecting column 10 is located on the side of the mounting column 13 away from the steel wire rope 5. The connection relationship between the first connecting column 8, the second connecting column 10 and the mounting column 13 is as shown in Figure 2 and Figure 3 ​As shown, the first connecting column 8 and the second connecting column 10 are fixedly connected with the mounting column 13, when the first connecting column 8 or the second connecting column 10 rotates, the mounting column 13 is driven to rotate, thereby driving the second connecting column 10 or the first connecting column 8 on the other side to rotate.

[0030] Further, the lever module further comprises a contact plate 7 and a counterweight 11, the contact plate 7 is threadedly connected to the first connecting column 8 on the side close to the steel wire rope 5, the counterweight 11 is fixedly sleeved on the end of the second connecting column 10 away from the mounting column 13, when the steel wire rope 5 is in the taut state, the side of the contact plate 7 contacts with the steel wire rope 5, although the contact plate 7 contacts between the steel wire rope 5, the contact plate 7 will not cause abrasion to the steel wire rope 5, and when the contact plate 7 contacts with the steel wire rope 5, the first connecting column 8 and the second connecting column 10 are in the balanced state, that is, as shown Figure 2 The steel wire rope 5 is in the state of being taut and straight, at this time, the steel wire rope 5 tightly presses the contact plate 7 on the side of the first connecting column 8, due to the existence of the counterweight 11, at this time, the first connecting column 8 and the second connecting column 10 are in the balanced state, and at this time, the mounting column 13 will not rotate.

[0031] It is worth mentioning that the detection module comprises a proximity switch 9 and an induction block 12, the proximity switch 9 is arranged on the upper surface of the mounting bottom plate 1 through a supporting block, the induction block 12 is arranged on the side of the second connecting column 10, the upper surface of the mounting bottom plate 1 is provided with a control system, and the proximity switch 9 is electrically connected with the control system, the proximity switch 9 is non-contact, thereby preventing the equipment from rusting due to dampness, causing the travel switch to be dead and unable to send signals, thereby improving the stability and reliability of the detection module, when the steel wire rope 5 appears the phenomenon of loose rope, the steel wire rope 5 is no longer in the state of being taut and straight, the steel wire rope 5 will be warped to the side, therefore, at this time, the steel wire rope 5 will no longer contact with the contact plate 7 on the side of the first connecting column 8, due to the existence of the counterweight 11, at this time, the first connecting column 8 and the second connecting column 10 are in the unbalanced state, the counterweight 11 drives the mounting column 13 to rotate to the direction of the counterweight 11 under the action of gravity, and at this time, the induction block 12 on the side of the second connecting column 10 will follow the movement, when the induction block 12 is inducted by the proximity switch 9, the induction block 12 will send a signal to the control system, thereby achieving the effect of alarm, thereby avoiding the phenomenon of loose rope, the steel wire rope 5 is curled together, the phenomenon of disorderly rope occurs, and thereby avoiding the loss caused by continuing to work on the trash cleaner.

[0032] Although the embodiments of the present application have been shown and described, it is to be understood that for the purpose of the present application, the embodiments can be changed, modified, replaced and varied in many ways without departing from the principles and spirit of the present application, the scope of the present application is defined by the appended claims and their equivalents.
