Detailed Embodiment

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment 1

[0029] Please refer to Figures 1-6 , a heavy cable winding and unwinding assisting device, including a cable winding and unwinding frame 1, and a winding and unwinding assisting mechanism 2 for assisting in the winding and unwinding of heavy cables is provided on one side of the cable winding and unwinding frame 1;

[0030] The winding and unwinding assisting mechanism 2 includes an installation groove 201 provided on one side of the cable winding and unwinding frame 1, a sliding shell 202 slidably arranged between two installation grooves 201, and a driving shaft 203 and a driven shaft 204 rotatably arranged on the sliding shell 202. Driving wheels 205 and driven wheels 206 are respectively provided on the driving shaft 203 and the driven shaft 204. Arc-shaped grooves for squeezing heavy cables are provided on both the driving wheel 205 and the driven wheel 206. A power assembly for driving the driving wheel 205 and the driven wheel 206 to rotate is arranged in the sliding shell 202.

[0031] Furthermore, the power assembly includes a driving motor 207 arranged in the sliding shell 202 and driven gears 208 arranged at the lower ends of the driving shaft 203 and the driven shaft 204. A driving gear 209 is provided at the output end of the driving motor 207. One side of the driving gear 209 meshes with the driven gear 208 at the lower end of the driving shaft 203;

[0032] A transmission gear 210 is also arranged in the sliding shell 202. The other side of the driving gear 209 meshes with the transmission gear 210, and the transmission gear 210 meshes with the driven gear 208 at the lower end of the driven shaft 204.

[0033] Furthermore, positioning blocks are provided on both sides of the sliding shell 202. The positioning blocks are fixedly arranged with the installation groove 201 through locking bolts, and the appropriate winding and unwinding angle of the cable is selected by adjusting the position of the sliding shell 202 between the two installation grooves 201.

[0034] When winding and unwinding heavy cables, the heavy cable reel is placed between the cable winding and unwinding frames 1, and then the heavy cable is manually pulled to realize the winding and unwinding of the cable. Since the outer diameter of most heavy cables is more than 20 millimeters, it is very difficult to quickly wind and unwind heavy cables only by manual pulling, and a assisting device must be added to improve the winding and unwinding efficiency of heavy cables;

[0035] The utility model is provided with a winding and unwinding assisting mechanism 2 on one side of the cable winding and unwinding frame 1. By means of the arrangement of the driving wheel 205 and the driven wheel 206 in the winding and unwinding assisting mechanism 2, the heavy cable between the driving wheel 205 and the driven wheel 206 is pulled by the rotation of the driving wheel 205 and the driven wheel 206, greatly reducing the manual participation in the winding and unwinding of the heavy cable;

[0036] The driving components in the sliding shell 202 are used to drive the driving wheel 205 and the driven wheel 206 to rotate, so as to realize the winding and unwinding function of the heavy cable. The specific driving principle is as follows: after the driving motor 207 is started, it will drive the driving gear 209 to rotate. The rotation of the driving gear 209 can not only drive the driven gear 208 at the lower end of the driving shaft 203 to rotate, but also drive the transmission gear 210 to rotate. At this time, the rotation direction of the driving shaft 203 is opposite to the rotation direction of the output end of the driving motor 207;

[0037] After the transmission gear 210 rotates, it can drive the driven gear 208 at the lower end of the driven shaft 204 to rotate, thus realizing the rotation of the driven shaft 204. At this time, the rotation direction of the driven shaft 204 is the same as the rotation direction of the output end of the driving motor 207;

[0038] Since the driving wheel 205 and the driven wheel 206 are respectively arranged on the driving shaft 203 and the driven shaft 204, and arc grooves for extruding the heavy cable are arranged on both the driving wheel 205 and the driven wheel 206, when the driving shaft 203 and the driven shaft 204 rotate, the heavy cable arranged between the two can be extruded, reducing manual participation and greatly improving the winding and unwinding efficiency of the heavy cable.

[0039] Embodiment 2

[0040] Please refer to Figures 4-6 , this embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. For the same parts, please refer to each other and will not be elaborated here.

[0041] As a further technical solution of this embodiment, an anti-slip component 3 for laterally pressing the outer side of the heavy cable is arranged on the driven wheel 206; the anti-slip component 3 includes a pressing rod 301 slidably arranged in the driven shaft 204, a pressing member 302 rotatably arranged on the pressing rod 301, a plurality of pressure-receiving members 303 slidably arranged on the driven wheel 206, and a driving component arranged in the sliding shell 202 for driving the pressing rod 301 to move vertically;

[0042] The plurality of pressure-receiving members 303 are arranged in a spoke shape, and the pressing member 302 abuts against the plurality of pressure-receiving members 303.

[0043] Further, the extruding member 302 is composed of an extrusion disc 3021 and a conical extrusion block 3022 arranged at the lower end of the extrusion disc 3021. The pressed member 303 is composed of an L-shaped sliding member 3031 and an arc-shaped extrusion head 3032. The lower end surface of the conical extrusion block 3022 abuts against the upper end surface of the L-shaped sliding member 3031.

[0044] Further, the driving assembly includes a guide rod 304 and a bidirectional lead screw 305 arranged in the sliding housing 202, two sliding blocks 306 slidably arranged in the sliding housing 202, and an extrusion plate 307 arranged on the sliding block 306. Through holes for the use of the guide rod 304 are formed in the sliding block 306, and internal threaded holes for the use of the bidirectional lead screw 305 are also formed in the sliding block 306;

[0045] The driving assembly further includes a wedge-shaped driven member 308 arranged on the extrusion rod 301. The wedge-shaped driven member 308 is arranged between the two extrusion plates 307, and one end of each of the two extrusion plates 307 can abut against the wedge-shaped driven member 308.

[0046] Further, a receiving cavity for the sliding of the pressed member 303 is formed in the driven wheel 206. Generally, the pressed member 303 is inside the receiving cavity. When the heavy cable slips during winding and unwinding, the arc-shaped extrusion head 3032 in the pressed member 303 extends out of the receiving cavity in the driven wheel 206, thereby eliminating the slipping phenomenon.

[0047] Since the movement of the heavy cable is driven by the frictional force generated when the driving wheel 205 and the driven wheel 206 rotate, in order to prevent the heavy cable from slipping between the driving wheel 205 and the driven wheel 206 (the frictional force generated by the driving wheel 205 and the driven wheel 206 on the heavy cable is less than the traction force required for the movement of the heavy cable), a non-slip assembly 3 for laterally pressing the outer side of the heavy cable is provided on the driven wheel 206. By increasing the extrusion force of the driven wheel 206 on the heavy cable, the frictional force is increased, thereby eliminating the slipping phenomenon of the heavy cable;

[0048] The working principle of the non-slip assembly 3 is as follows: When the vertically slidably arranged extrusion rod 301 moves under the drive of the driving assembly, the extrusion rod 301 will drive the extruding member 302 to move downward. Since the extruding member 302 is rotatably arranged on the extrusion rod 301 and the extruding member 302 abuts against a plurality of pressed members 303, when the extruding member 302 moves downward, it will drive the pressed members 303 to move;

[0049] The specific extrusion process is as follows: The extruding member 302 is composed of an extrusion disc 3021 and a conical extrusion block 3022 arranged at the lower end of the extrusion disc 3021. The pressed member 303 is composed of an L-shaped sliding member 3031 and an arc-shaped extrusion head 3032, and the lower end surface of the conical extrusion block 3022 abuts against the upper end surface of the L-shaped sliding member 3031;

[0050] Therefore, when the conical extrusion block 3022 moves downward, it will drive the L-shaped sliding member 3031 to move laterally, and then drive the arc-shaped extrusion head 3032 arranged in the driven wheel 206 to extend. After the extended arc-shaped extrusion head 3032 extrudes the heavy cable, the extrusion force on the heavy cable is increased, that is, the frictional force generated by the driving wheel 205 and the driven wheel 206 on the heavy cable during rotation is increased.

[0051] The working principle of the driving component in the anti-slip component 3 is as follows: The operator turns the nut arranged at one end of the bidirectional lead screw 305, so that the bidirectional lead screw 305 rotates. Since the bidirectional lead screw 305 is provided with a bidirectional thread section, after the bidirectional lead screw 305 rotates, it can drive both sliding blocks 306 to move towards the center, that is, towards the wedge-shaped driven member 308. Since the sliding blocks 306 are provided with extrusion plates 307, and one end of each of the two extrusion plates 307 can abut against the wedge-shaped driven member 308, when the two extrusion plates 307 move towards the wedge-shaped driven member 308, they can extrude the wedge-shaped driven member 308, and then the whole wedge-shaped driven member 308 moves downward. Since the extrusion rod 301 is fixedly arranged with the wedge-shaped driven member 308, when the whole wedge-shaped driven member 308 moves downward, it will drive the extrusion rod 301 to move downward, so that the arc-shaped extrusion head 3032 extends.

[0052] Each embodiment in this specification is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other. For the above embodiments, since they are basically similar to the method embodiments, the description is relatively simple.
