[0028] To solve the above problems, please refer to Figures 1 to 4The present invention provides an insulating rope winding device, including a shell 1, a winding structure and a self-locking member 5. The shell 1 has an installation cavity 11 and an outlet 12. The outlet 12 is connected to the installation cavity 11, and the insulating rope is pulled out through the outlet 12. The winding structure includes a winding assembly 2 and a rope assembly 3. The winding assembly 2 is arranged in the installation cavity 11 and is used to wind up the insulating rope. The winding assembly 2 and the rope assembly 3 are connected by a belt 4. The winding assembly 2 drives the rope assembly 3 to rotate at the same frequency as the winding assembly 2 through the belt 4. The rope assembly 3 is provided with a limiting hole 321, and the insulating rope passes through the limiting hole 321 and emerges at the outlet 12. The self-locking member 5 is movably connected to the rope assembly 3 to control the operation of the winding structure. The shell 1 and the winding structure are made of insulating hard plastic, such as polyethylene or polyvinyl chloride, which has good wear resistance and insulation performance, high safety, and extends the service life of the winding device.

[0029] In an optional embodiment, if Figure 1 and Figure 2 As shown, the rope arrangement assembly 3 includes a reciprocating screw 31, a slider 32 and a guide rod 33. The reciprocating screw 31 is arranged in parallel with the guide rod 33. One end of the slider 32 is movably sleeved on the reciprocating screw 31, and the other end is movably sleeved on the guide rod 33, and moves along the length direction of the reciprocating screw 31 and the guide rod 33. The slider 32 is provided with the limiting hole 321, and the limiting hole 321 is located between the reciprocating screw 31 and the guide rod 33. One end of the reciprocating screw 31 is provided with a gear 34, and the gear 34 is meshed with the self-locking member 5. Specifically, a rotating shaft is provided at one end of the reciprocating screw 31, and a belt 4 connects the rotating shaft of the reciprocating screw 31 and the rotating shaft 211 of the winding structure, so that when the winding structure rotates, the reciprocating screw 31 is driven to rotate so that the slider 32 moves along the length direction of the reciprocating screw 31, and the insulating rope can be reciprocatedly wound or pulled out.

[0030] In an optional embodiment, if Figure 1 and Figure 2 As shown, the inner wall of the housing 1 is provided with a first limiting column 17, and the two ends of the reciprocating screw 31 are movably sleeved on the circumference of the first limiting column 17. Specifically, the first limiting column 17 is arranged at an open position to facilitate the installation of the reciprocating screw 31, and the reciprocating screw 31 rotates along the first limiting column 17 as the central axis.

[0031] In an optional embodiment, if Figure 1 and Figure 2As shown, the self-locking member 5 includes a one-way ratchet 51 and a pawl 52 . The circumferential side of the one-way ratchet 51 is meshed with the gear 34 , and one end of the pawl 52 is movably connected to the one-way ratchet 51 . Specifically, the inner wall of the shell 1 is also provided with a third limit column 53, and the one-way ratchet 51 is sleeved on the third limit column 53 and rotates with the reciprocating screw 31 with the third limit column 53 as the axis.

When the staff pulls the insulating rope from the winding device, the pawl 52 will not be stuck in the tooth portion of the one-way ratchet 51. When the staff pulls out the required length of the insulating rope, the self-recovery performance of the winding component 2 is used to drive the one-way ratchet 51 to rotate in the opposite direction. At this time, the pawl 52 can be stuck in the tooth portion of the one-way ratchet 51, so that the winding device cannot recycle the insulating rope in use. When the insulating rope is used up, the end of the pawl 52 is manually separated from the tooth portion of the one-way ratchet 51, and the separation state is maintained to recover the insulating rope by utilizing the self-recovery performance of the winding component 2.

[0032] In an optional embodiment, if Figure 1 and Figure 4 As shown, the winding assembly 2 includes a winding frame 21 and a winding spring 22. The winding frame 21 is provided with a rotating shaft 211. The insulating rope is wound around the rotating shaft 211. The winding spring 22 is provided at one end of the rotating shaft 211, and the other end is connected to the rope arrangement assembly 3 through the belt 4. Specifically, the inner wall of the shell 1 is provided with a second limiting column 18, and the two ends of the rotating shaft 211 are respectively sleeved on the circumferential side of the second limiting column 18, and the rotating shaft 211 can be rotated by the second limiting column 18 as the rotating shaft 211, and the connection stability between the reel 21 and the shell 1 is improved to prevent the reel 21 from shaking during the rotation process. A fixing buckle is provided on the circumferential side of the rotating shaft 211, and one end of the insulating rope can be detachably connected to the fixing buckle to prevent the insulating rope from being separated from the reel 21, thereby improving the connection stability between the insulation and the reel 21, and facilitating the removal and replacement of insulating ropes of different specifications, such as 10 meters, 15 meters or 20 meters; when the insulating rope is pulled out, the reel 21 rotates, so that when the coil spring 22 is deformed, its internal molecules The structure will change, forming a temporary new shape and accumulating force. After the staff stops pulling the insulating rope, the internal stress of the coil spring 22 will push the coil spring 22 to automatically restore to its original shape. In this process, the insulating rope is retracted into the installation cavity 11 and wound around the rotating shaft 211. This process is used to replace the insulating rope: pull out the insulating rope completely to expose the fixing buckle, pass one end of the new insulating rope through the limiting hole 321 of the slider 32 and connect it to the fixing buckle, untie the original insulating rope and take it out, and use the automatic recovery ability of the coil spring 22 to reel the new insulating rope into the reel-up frame 21; further, a limiting block is provided at the end where the insulating rope is pulled out to prevent the insulating rope and the wire end from being retracted into the reel-up, which is convenient for next use.

[0033] In an optional embodiment, if Figure 1 and Figure 2 As shown, the reeling frame 21 further includes two baffles 212 and a connecting plate 213. The two baffles 212 are respectively arranged at the two ends of the rotating shaft 211, and the end of the rotating shaft 211 is protruded from the baffles 212. The cross section of the reeling frame 21 is in the shape of an "I". The connecting plate 213 is connected to the housing 1 and is arranged parallel to the baffles 212 and close to one of the baffles 212. One end of the rotating shaft 211 is sequentially passed through the baffles 212 and the connecting plate 213, and the coil spring 22 is arranged on the connecting plate 213. Specifically, the baffle 212 and the rotating shaft 211 are an integrally formed structure with good connection strength and stability, and the baffle 212 can limit the winding range of the insulating rope, prevent the insulating rope from being separated from the rotating shaft 211, and affect the normal operation of other components, thereby extending the service life of the reeling device.

[0034] In an optional embodiment, if Figure 4 As shown, a limiting protrusion 214 is provided on the surface of the connecting plate 213 away from the baffle 212, one end of the coil spring 22 is connected to the rotating shaft 211, and the other end is wound around the rotating shaft 211 and connected to the limiting protrusion 214. Specifically, one end of the coil spring 22 hooks the peripheral side of the limiting protrusion 214 for stable installation, and can also be connected by a snap-on method.

[0035] In an optional embodiment, if Figure 1 and Figure 2 As shown, the housing 1 is a split structure for replacing the insulating rope. Specifically, the housing 1 includes a first shell 14 and a second shell 15, the first shell 14 and the second shell 15 are connected by screws, and the connecting piece is connected to the first shell 14. After the staff removes the screws, the second shell 15 can be separated from the first shell 14, so that the reel-up frame 21 is exposed, which is convenient for replacing the insulating rope. In this embodiment, the first shell 14 is close to the belt 4, and the second shell 15 is provided with a connecting plate 213. The first shell 14 and the second shell 15 are both provided with a first limiting column 17, and the gear 34 of the reciprocating screw 31 is arranged on the side of the reciprocating screw close to the second shell 15.

[0036] In an optional embodiment, if Figure 2 As shown, the housing 1 is provided with a base 13, and the base 13 is used to stably place the insulating rope winding device. Specifically, the housing 1 and the base 13 are an integrally formed structure, which has good connection stability. Since the winding device is placed on the ground for use, the base 13 allows the winding device to be stably placed on the ground, effectively avoiding pulling out or retracting the insulating rope, shaking the winding device, or being stable and not tipping over when placed on an insulating boom truck.

[0037] In an optional embodiment, if Figure 2 As shown, the housing 1 is provided with a hole 16 , which is arranged corresponding to the central axis of the reeling assembly 2 and is used for adding lubricant; the housing 1 is provided with a cover 6 , which is used for sealing the hole 16 .

[0038] When in use, pull the insulating rope to protrude from one end of the insulating rope winding device. While the winding frame 21 rotates around its rotating shaft 211, the coil spring 22 is deformed to form a temporary new shape and accumulate force, and the reciprocating screw 31 rotates accordingly through the transmission of the belt 4, driving the slider 32 to make reciprocating linear motion along the length direction of the reciprocating screw 31. When the length of the insulating rope reaches the required length, the self-locking member 5 limits the rotation of the reciprocating screw 31 to achieve self-locking. When it is necessary to retract the insulating rope, the pawl 52 is manually moved to separate the pawl 52 from the tooth portion of the one-way ratchet 51, and the pawl 52 is unlocked, so that the reciprocating screw 31 is restored to an operable state. The self-recovery property of the coil spring 22 is utilized to retract the insulating rope into the winding device, and at the same time, the guide rod 33 is cooperated to make the insulating rope evenly retracted on the winding frame 21.

[0039] In summary, the insulating rope winding device can quickly and automatically wind up the insulating rope, so that the wound insulating rope is neatly stored and not stepped on, and its insulating shell 1 is protected from damage. When the pulled-out length of the insulating rope reaches the required length, the self-locking part 5 is used to limit the operation of the rope arrangement assembly 3. At this time, the insulating rope cannot be retracted, and self-locking is achieved; the winding device has the characteristics of small size and can be placed in the insulating bucket without taking up too much space; the box of the device can be opened by oneself, and the insulating ropes of different lengths can be replaced by oneself.
