Description

Technical Field

[0001] This utility model relates to the field of cable winch technology, specifically a cable-laying winch for power supply vehicles. Background Technology

[0002] The cable winch of a power supply vehicle is a traction device installed on the power supply vehicle. It is mainly used to provide traction in emergency situations to help vehicles get out of trouble or tow other vehicles. It usually consists of a motor, steel cable or synthetic fiber cable, drum, control device and other parts.

[0003] When the cable winch is connected to other vehicles via the hook at the front end for pulling operations, if the support anchor point is only used at the contact point between the cable and the spool, and the vehicle is pulled to move, the spool of the cable winch is likely to deform or be damaged under the pull of the cable due to the weight of the vehicle. Therefore, it is necessary to design a cable winch for power vehicles that can greatly reduce the pressure on the cable spool during pulling. Utility Model Content

[0004] The purpose of this invention is to provide a power supply vehicle cable winch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power vehicle cable winch, comprising a winch body, a cable being provided on the surface of the spool of the winch body, a hook being fixedly connected to one end of the cable, a fixing rod being fixedly connected to one side of the winch body, a limit rod being fixedly connected to the inner side of the two fixing rods, a slip ring being slidably connected to the surface of the limit rod, a fixing plate being fixedly connected to one side of the slip ring, a second hinge being fixedly connected to the side of the fixing plate away from the slip ring, a fixing block being rotatably connected to the fixing plate through the second hinge, a clamping ring being fixedly connected to the end of the fixing block away from the second hinge, and a fixing ring being provided on the surface of the clamping ring.

[0006] Preferably, hinges are fixedly connected to both the upper and lower ends of the two clamping rings. The clamping rings are rotatably connected to the fixed rings through the hinges. A pin is fixedly connected to the end of the fixed ring away from the hinges. Insertion holes are provided at the top and bottom of the two fixed blocks. The pins are movably inserted into the inner wall of the insertion holes.

[0007] Preferably, a protective rubber sleeve is fixedly connected to the surface of the cable, and the end of the cable away from the hook is fixedly connected to the surface of the winch main body spool.

[0008] Preferably, a fixing rubber ring is fixedly connected to the inner wall of the clamping ring.

[0009] Preferably, a micro motor is fixedly installed inside one end of the winch body fixing plate, and a stop bar is fixedly connected to the drive shaft end of the micro motor. A recycling groove is opened on the inner side of the winch body fixing plate, and the stop bar is slidably connected to the inner wall of the recycling groove.

[0010] Preferably, the surface of the winch main shaft is provided with a spiral groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model, by setting a fixing plate and a clamping ring, not only limits the cable but also, when the cable needs to be pulled, uses a protective rubber sleeve and a fixing rubber ring to assist in fixing the cable by utilizing the coefficient of friction between the two. This greatly reduces the traction force of the cable on the main shaft of the winch, thus protecting the main shaft of the winch.

[0013] This utility model, by setting a stop bar, can control the cable margin, thereby playing a role in safe operation buffering and dynamic load adaptation, so as to ensure the normal operation of the winch body. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a power vehicle cable winch, including a winch body 1, a cable 15 is provided on the surface of the spool of the winch body 1, a hook 3 is fixedly connected to one end of the cable 15, a fixing rod 5 is fixedly connected to one side of the winch body 1, a limit rod 4 is fixedly connected to the inner side of the two fixing rods 5, a slip ring 6 is slidably connected to the surface of the limit rod 4, a fixing plate 10 is fixedly connected to one side of the slip ring 6, a hinge 11 is fixedly connected to the side of the fixing plate 10 away from the slip ring 6, a fixing block 12 is rotatably connected to the fixing plate 10 through the hinge 11, a clamping ring 13 is fixedly connected to the end of the fixing block 12 away from the hinge 11, by fixing the cable 15, the traction force of the cable 15 on the spool of the winch body 1 is reduced, and a fixing ring 8 is provided on the surface of the clamping ring 13.

[0022] Furthermore, hinges 9 are fixedly connected to both the upper and lower ends of the two clamping rings 13. The clamping rings 13 are rotatably connected to the fixed rings 8 through the hinges 9. A pin 7 is fixedly connected to the end of the fixed rings 8 away from the hinges 9, which can clamp and fix the two clamping rings 13. Insertion holes are opened at the top and bottom of the two fixing blocks 12, and the pin 7 is movably inserted into the inner wall of the insertion hole.

[0023] Furthermore, a protective rubber sleeve 2 is fixedly connected to the surface of the cable 15, which not only protects the cable 15, but also increases the coefficient of friction when the cable 15 is fixedly fixed. The end of the cable 15 away from the hook 3 is fixedly connected to the surface of the spool of the winch body 1.

[0024] Furthermore, a fixing rubber ring 14 is fixedly connected to the inner wall of the clamping ring 13 to increase the coefficient of friction and thus enhance the fixing effect.

[0025] Furthermore, a micro motor 16 is fixedly installed inside one end of the fixed plate of the winch body 1. A stop bar 17 is fixedly connected to the drive shaft end of the micro motor 16, which can perform a margin control operation on the cable 15, thereby preventing the cable 15 from being insufficient and thus damaging the winch body 1. A recycling groove is opened on the inner side of the fixed plate of the winch body 1, and the stop bar 17 is slidably connected to the inner wall of the recycling groove.

[0026] Furthermore, the surface of the spool of the winch body 1 is provided with a spiral groove to assist the cable 15 in the retraction and limiting operation, thereby preventing the cable 15 from stacking during the retraction process.

[0027] Working principle: Before the winch body 1 needs to be pulled, the micro motor 16 is started first. The micro motor 16 rotates and lowers the stop bar 17, which restricts the tail end of the cable 15. Because the winch body 1 needs to retain about two meters of slack when pulling, it plays a role in safe operation buffer and dynamic load adaptation, so as to ensure the normal operation of the winch body 1. Then, the cable 15 is pulled outward so that the hook 3 is hooked onto another vehicle. After the hook 3 is hooked, the hinge 11 rotates and closes the clamps 13 on both sides, thereby wrapping the cable 15. Then, by rotating the fixing ring 8 through the hinge 9, the hinges 9 of the two fixing rings 8 are respectively inserted into the insertion holes on the top of the fixing block 12 on the other side, thereby clamping and fixing the clamping ring 13. Since the outer side of the cable 15 is wrapped with a protective rubber sleeve 2 and the inner side of the clamping ring 13 is fixedly connected with a fixing rubber ring 14, when the power trolley is pulled by the winch body 1, the coefficient of friction between the protective rubber sleeve 2 and the fixing rubber ring 14 can greatly reduce the pulling force of the cable 15 on the spool of the winch body 1, thereby ensuring the traction force while also protecting the spool of the winch body 1.
