The utility model is composed of a winch base, a winch drum, a connecting seat, a connecting rod, a tension spring, a switch bracket, a switch limit plate, and a position switch; when the wire rope wound on the winch is out of the groove, in a mess, or biting the rope, the connecting rod rotates, causing the switch limit plate to separate from the position switch and issue an alarm, so that the operator can timely discover the problems of the wire rope wound on the winch, and the operator can take measures in time to avoid the occurrence of safety accidents; by setting an adjusting bolt to finely adjust the initial position of the connecting rod, the applicability of the utility model is better; however, with the operation of the winch, the wire rope winds onto the winch drum, increasing the force between the contact rod and the wire rope, accelerating the wear of the contact rod, and reducing the service life of the detection mechanism.

[0004] In order to solve the above problems, we made improvements and proposed a wire rope out-of-groove detection mechanism for a winch. Content of the Utility Model

Specific embodiments

[0020] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model.

[0021] Embodiment: As Figure 1-3 shown, a wire rope out-of-groove detection mechanism for a winch includes a base plate 1. A hoisting drum 2 is fixedly connected to the middle of the top end of the base plate 1. A slide rail 8 is fixedly connected to the rear side of the top end of the base plate 1. A motor 10 is fixedly connected to the rear end of the slide rail 8. The output end of the motor 10 is fixedly connected to a threaded rod 9. The outer side of the threaded rod 9 is threadedly connected to a mounting rod 11, and the bottom end of the mounting rod 11 is slidably connected inside the slide rail 8. A detection mechanism is fixedly installed at the top end of the mounting rod 11. A control single-chip microcomputer is arranged inside the motor 10 to control the operation of the motor 10. After a layer of wire rope is wound around the surface of the hoisting drum 2, the motor 10 operates to drive the threaded rod 9 to rotate. The rotating threaded rod 9 drives the bottom end of the mounting rod 11 to slide inside the slide rail 8 and push backward, so that the detection mechanism moves backward a certain distance to cooperate with the increase in the winding thickness of the wire rope, avoiding the aggravation of wear at the contact position between the detection mechanism and the wire rope, and prolonging the service life of the detection mechanism.

[0022] Specifically, as Figure 2 and Figure 3As shown in the figure, the detection mechanism includes a U-shaped frame 3, and the U-shaped frame 3 is fixedly connected to the top of the mounting rod 11. A cross plate 4 is fixedly connected to the front side of the U-shaped frame 3. Connecting rods 17 are installed on both the left and right sides of the cross plate 4, and the rear ends of the connecting rods 17 penetrate to the rear end of the U-shaped frame 3. The front ends of the two connecting rods 17 are fixedly connected to a straight rod 7. A wear-resistant coating is applied to the outer surface of the straight rod 7. Folding plates 18 are arranged on both the left and right sides of the rear end of the U-shaped frame 3. A second spring 20 is fixedly connected between the folding plate 18 and the U-shaped frame 3. A second switch 19 is arranged inside the second spring 20, and the second switch 19 is opposite to the connecting rod 17. The second switch 19 is connected to a buzzer. During the process of the hoisting drum 2 winding the steel wire rope, if the steel wire rope gets out of the groove, the winding of the steel wire rope becomes uneven, that is, protrusions appear. The protrusions squeeze the straight rod 7, causing the connecting rod 17 to move backward along the cross plate 4 and the U-shaped frame 3, compressing the second spring 20, and making the rear end of the connecting rod 17 act on the second switch 19. The buzzer is turned on through the second switch 19 to send out an alarm signal for the steel wire rope getting out of the groove.

[0023] Specifically, as Figure 1 shown in the figure, second guide rails 14 are fixedly connected to both the left and right sides of the straight rod 7. Movable blocks 15 are slidably connected to the outer sides of the second guide rails 14. A first spring 16 is fixedly connected between the movable blocks 15 and the cross plate 4. A limiting rod 6 is fixedly connected to the rear end of the movable block 15, and the limiting rod 6 penetrates to the rear side of the cross plate 4. First switches 5 are fixedly connected to both the left and right sides inside the U-shaped frame 3, and the first switches 5 are opposite to the limiting rod 6. The first switches 5 cooperate with the motor 10. A limiting block is fixedly connected to the front end of the second guide rail 14, and a gap is provided between the rear end of the second guide rail 14 and the cross plate 4. During the process of the hoisting drum 2 winding the steel wire rope, when the steel wire rope reaches the end of the hoisting drum 2, the end steel wire rope stacks outward, and then acts on the movable block 15. The movable block 15 moves backward along the second guide rail 14, compressing the first spring 16, and the limiting rod 6 moves backward and acts on the first switch 5. The first switch 5 transmits a signal to the motor 10 to make the detection mechanism move backward automatically, which is more convenient to use.

[0024] Specifically, as Figure 2 shown in the figure, first guide rails 12 are fixedly connected to both the left and right sides of the top of the bottom plate 1. Support rods 13 are slidably connected to the outer sides of the first guide rails 12, and the top ends of the support rods 13 are fixedly connected to the U-shaped frame 3. The top of the support rod 13 is fixedly connected to the folding plate 18. During the movement of the U-shaped frame 3, the support rod 13 slides along the first guide rail 12 and supports the U-shaped frame 3, ensuring the stability of the detection mechanism.

[0025] Working principle: During the process of winding the wire rope around the hoist drum 2, the wire rope moves to the end of the hoist drum 2, and then the wire rope at the end is stacked outward, and then acts on the movable block 15. The movable block 15 moves backward along the second guide rail 14, so that the first spring 16 is compressed, and the limit rod 6 moves backward and acts on the first switch 5. The first switch 5 transmits a signal to the motor 10. The motor 10 drives the threaded rod 9 to rotate. The rotating threaded rod 9 drives the bottom end of the mounting rod 11 to slide inside the slide rail 8 through the thread, and pushes backward, thereby moving the detection mechanism backward a certain distance to match the increase in the winding thickness of the wire rope, avoid aggravated wear of the contact position between the detection mechanism and the wire rope, and extend the service life of the detection mechanism.

[0026] During the process of winding the wire rope on the winch drum 2, the wire rope derailed, causing the winding of the wire rope to become uneven, i.e., a bulge appeared. The bulge squeezed the straight rod 7, causing the connecting rod 17 to move backward along the cross plate 4 and the V-shaped frame 3, compressing the second spring 20 and causing the rear end of the connecting rod 17 to act on the second switch 19, which turns on the buzzer through the second switch 19 and sends out an alarm signal that the wire rope is derailed.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
