Detailed implementation manner

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners:

[0021] As Figure 1 shown, the present utility model provides an insulating power cable winding device, including a base 101. Four corners of the bottom of the base 101 are fixedly connected with support legs 102. The bottoms of the four support legs 102 are fixedly connected with universal wheels 103. Two symmetrically arranged side plates 106 are fixedly connected to the top of the base 101. A dust collection drawer 104 located between the two side plates 106 is slidably connected to the front side of the top of the base 101. A handle 105 is fixedly connected to the front side wall of the dust collection drawer 104. A winding assembly 2 is arranged on the rear sides of the opposite side walls of the two side plates 106. A reciprocating movement assembly 3 located between the two side plates 106 is arranged in front of the winding assembly 2. A cleaning assembly 4 is fixedly connected to the top of the reciprocating movement assembly 3.

[0022] The base 101 provides a stable support foundation. The support legs 102 at the four corners of its bottom raise the base 101. The universal wheels 103 at the bottoms of the support legs 102 enable the device to be flexibly moved to the required position. By holding the handle 105, the operator can pull out the dust collection drawer 104 from the front side of the top of the base 101 to collect dust and debris generated during the winding and cleaning processes.

[0023] As Figure 2 、 Figure 3 、 Figure 4As shown in the figure, the coiling assembly 2 includes a servo motor 201. The left side wall of the servo motor 201 is fixedly connected to the right side wall of the right end side plate 106. The output end of the servo motor 201 penetrates through to the left side wall of the right end side plate 106 and is fixedly connected to a rotating roller 208. A sliding sleeve 203 is slidably connected to the outer wall of the right end of the rotating roller 208. The left side wall of the sliding sleeve 203 is fixedly connected to a rotating ring 212. A plurality of annularly distributed connecting rods one 204 are rotatably connected to the outer wall of the rotating ring 212. One end of the connecting rod one 204 away from the rotating ring 212 is rotatably connected to a convex strip 210. One side of the convex strip 210 away from the rotating roller 208 is fixedly connected to an arc-shaped coiling plate 205. A plurality of equidistantly distributed circular holes 202 are formed in the outer wall of the right side of the rotating roller 208. A screw 213 passing through the circular groove formed in the outer wall of the sliding sleeve 203 is inserted into the rear side of the circular hole 202. The size of the screw 213 is adapted to that of the circular hole 202, and a nut is threadedly connected to the rear end thereof.

[0024] As Figure 2 , Figure 3 , Figure 4 shown in the figure, side baffles 209 are fixedly connected to both the left and right ends of the arc-shaped coiling plate 205. A plurality of equidistantly distributed fixing rings 207 are fixedly connected to the outer wall of the rotating roller 208. A plurality of annularly distributed connecting rods two 206 are rotatably connected to the outer wall of the fixing ring 207. One end of the connecting rod two 206 away from the fixing ring 207 is rotatably connected to the convex strip 210. The left end of the rotating roller 208 penetrates through to the left side wall of the left end side plate 106 and is fixedly connected to a rotating disc one 211.

[0025] When the position of the arc-shaped coiling plate 205 needs to be adjusted, the sliding sleeve 203 can slide on the outer wall of the right end of the rotating roller 208. By adjusting the position of the sliding sleeve 203, the rotating ring 212, the connecting rod one 204 and the convex strip 210 drive the arc-shaped coiling plate 205 to move to a suitable position to adapt to cables of different diameters. After determining the position, insert the screw 213 into the circular groove of the sliding sleeve 203 and pass through the corresponding circular hole 202, and then tighten and fix it with a nut. The side baffles 209 at both the left and right ends of the arc-shaped coiling plate 205 can prevent the cable from slipping during the coiling process. The fixing rings 207 and the connecting rods two 206 on the rotating roller 208 provide additional stability for the coiling structure.

[0026] When winding up the cable, the servo motor 201 is started. It drives the rotating roller 208 to rotate. The rotating roller 208 drives the fixed ring 207 fixed thereto to rotate. The rotation of the fixed ring 207 drives the second connecting rod 206, the convex strip 210, and the arc-shaped winding plate 205 to rotate. At the same time, the rotating ring 212 and the sliding sleeve 203 will also rotate with the rotating roller 208, thereby driving the first connecting rod 204 to rotate, realizing the rotation of the arc-shaped winding plate 205, so as to complete the winding of the cable, enabling the device to adapt to various insulating power cables with different diameters, improving the versatility and applicability of the device, and reducing the trouble of replacing different winding rollers due to the difference in cable diameters.

[0027] As Figure 4 shown, the reciprocating movement assembly 3 includes a second rotating disk 301. The outer wall of the second rotating disk 301 is drivingly connected to the first rotating disk 211 through a belt provided. The right end of the second rotating disk 301 is fixedly connected to a reciprocating lead screw 302 that penetrates through the left side wall of the right end side plate 106. The outer wall of the reciprocating lead screw 302 is threadedly connected to a reciprocating nut 303. The right side wall of the reciprocating nut 303 is slidably connected to a slide bar 304 through two symmetrically arranged circular groove holes in the front and back. The left and right ends of the two slide bars 304 are fixedly connected to the opposite side walls of the left and right side plates 106 respectively.

[0028] The first rotating disk 211 at the left end of the rotating roller 208 drives the second rotating disk 301 to rotate through a belt, so that the reciprocating lead screw 302 rotates. Under the action of the reciprocating lead screw 302, the reciprocating nut 303 makes a reciprocating movement along the slide bar 304, avoiding the cable from accumulating at a certain place, thereby achieving a neater and tighter winding effect, preventing winding and knotting, and improving the winding quality and the convenience of subsequent use.

[0029] As Figure 5As shown in the figure, the cleaning component 4 includes a fixed frame 401. The bottom of the fixed frame 401 is fixedly connected to the top of the reciprocating nut 303. The right side wall of the fixed frame 401 is fixedly connected to a motor 402. The output end of the motor 402 is fixedly connected to a pulley one 403. The outer wall of the pulley one 403 is connected to a pulley two 404 through a belt provided. The inner wall of the pulley two 404 is fixedly connected to a rotating shaft one 406. The bottom of the rotating shaft one 406 penetrates through the inner top wall of the fixed frame 401 and is fixedly connected to a cleaning brush 405. The number of cleaning brushes 405 is two and they are symmetrically arranged left and right. The bottoms of the two cleaning brushes 405 are rotatably connected to the inner bottom wall of the fixed frame 401. The top of the rotating shaft one 406 penetrates through the top of the pulley two 404 and is fixedly connected to a pulley three 407. The outer wall of the pulley three 407 is connected to a pulley four 408 through a belt provided. The bottom of the pulley four 408 is fixedly connected to a rotating shaft two 410. The bottom of the rotating shaft two 410 penetrates through the inner top wall of the fixed frame 401 and is fixedly connected to the cleaning brush 405 on the left end. The cable limiting plate 409 is fixedly connected to the rear side of the top end of the fixed frame 401.

[0030] When it is necessary to clean the dust on the surface of the cable, when the cable passes through the cleaning component 4, start the motor 402. The pulley one 403 at the output end of the motor 402 drives the pulley two 404 to rotate through the belt, and then the rotating shaft one 406 drives the cleaning brush 405 on the right side to rotate. At the same time, the pulley three 407 at the top of the rotating shaft one 406 drives the pulley four 408 to rotate through the belt, so that the rotating shaft two 410 drives the cleaning brush 405 on the left side to rotate, comprehensively cleaning the cable. The cable limiting plate 409 at the rear side of the top end of the fixed frame 401 can ensure the stable position of the cable during the cleaning process, realizing the cleaning of dust, impurities and dirt on the surface of the cable, and effectively preventing these pollutants from affecting its insulation performance during the use of the cable and reducing the risks of electric leakage and short circuit.

[0031] Next, the working principle of the insulating power cable winding equipment will be specifically described.

[0032] As Figures 1-5 shown in the figure, when it is necessary to adjust the position of the arc winding plate 205, the sliding sleeve 203 can slide on the outer wall of the right end of the rotating roller 208. By adjusting the position of the sliding sleeve 203, the rotating ring 212, the connecting rod one 204 and the convex strip 210 drive the arc winding plate 205 to move to a suitable position to adapt to cables of different diameters. After determining the position, insert the screw 213 into the circular groove of the sliding sleeve 203 and pass through the corresponding circular hole 202, and then tighten and fix it with a nut. The side baffle plates 209 at the left and right ends of the arc winding plate 205 can prevent the cable from slipping during the winding process. The fixing ring 207 and the connecting rod two 206 on the rotating roller 208 provide additional stability for the winding structure.

[0033] When winding up the cable, the servo motor 201 is started. It drives the rotating roller 208 to rotate. The rotating roller 208 drives the fixed ring 207 fixed thereto to rotate. The rotation of the fixed ring 207 drives the second connecting rod 206, the convex strip 210, and the arc-shaped winding plate 205 to rotate. At the same time, the rotating ring 212 and the sliding sleeve 203 will also rotate with the rotating roller 208, thereby driving the first connecting rod 204 to rotate, realizing the rotation of the arc-shaped winding plate 205, so as to complete the winding of the cable, enabling the device to adapt to various insulated power cables with different diameters, improving the versatility and applicability of the device, and reducing the trouble of replacing different winding rollers due to the difference in cable diameter.

[0034] The first rotating disk 211 at the left end of the rotating roller 208 drives the second rotating disk 301 to rotate through a belt, so that the reciprocating lead screw 302 rotates. Under the action of the reciprocating lead screw 302, the reciprocating nut 303 makes a reciprocating motion along the slide rod 304, avoiding the accumulation of the cable in a certain place, thereby achieving a neater and tighter winding effect, preventing winding and knotting, and improving the winding quality and the convenience of subsequent use.

[0035] When it is necessary to clean the dust on the surface of the cable, when the cable passes through the cleaning assembly 4, the motor 402 is started. The pulley one 403 at the output end of the motor 402 drives the pulley two 404 to rotate through a belt, and then the rotating shaft one 406 drives the cleaning brush 405 on the right side to rotate. At the same time, the pulley three 407 at the top of the rotating shaft one 406 drives the pulley four 408 to rotate through a belt, so that the rotating shaft two 410 drives the cleaning brush 405 on the left side to rotate, comprehensively cleaning the cable. The cable limiting plate 409 at the rear side of the top end of the fixed frame 401 can ensure the stable position of the cable during the cleaning process, realizing the cleaning of the dust, impurities and dirt on the surface of the cable, and effectively preventing these pollutants from affecting its insulation performance during the use of the cable and reducing the risk of leakage and short circuit.

[0036] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
