Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of power construction, and particularly relates to a cable winding device. BACKGROUND

[0002] In the field of power construction, the cable tensioning device is a crucial tool that provides the necessary tension during cable laying, installation, and recovery, ensuring the stability and safety of the cable. With the continuous development of power engineering and the increasingly stringent requirements for cable construction quality, traditional cable tensioning devices have gradually become difficult to meet the needs of modern power construction.

[0003] Traditional cable tensioning devices usually rely on manual operation or simple mechanical structures to achieve cable tensioning. These devices have many inconveniences in operation, such as uneven tensioning force, difficult adjustment, and high labor intensity. In addition, the safety of traditional devices also has certain hidden dangers, as the winding wheel may rotate more due to inertia, causing the cable to loosen or even entangle or knot.

[0004] When winding the cable, the tensioning force required for the outer circle of the cable is greater than that for the inner circle in order to maintain the same tightness. This is because when winding the cable, the outer circle of the cable has a larger winding circumference than the inner circle, and the outer circle of the cable needs to withstand more tension to maintain the tightness of the cable wound on the cable reel. When winding the cable, the outer circle of the cable needs to withstand greater tension to maintain the stability of the entire cable reel and the neat arrangement of the cable. The existing technology such as patent document CN118205956B usually provides a fixed size of mechanical force, so that some thicker cables are not evenly tensioned in the inner and outer circles when winding, causing the cable to loosen or even entangle or knot.

DETAILED DESCRIPTION

[0026] For better understanding of the present application, the content of the present application is further clarified below in combination with examples and drawings, but the protection content of the present application is not limited to the following examples only. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without one or more of these details.

[0027] Example 1: refer to Figures 1-6 The cable winding device of the present embodiment comprises a support frame 10, a winding disc 11 is rotatably arranged on the upper part of the support frame 10, a cable tensioning assembly, a guiding assembly 20 for uniformly winding the cable on the winding disc 11, and a synchronous assembly 40 for synchronously moving the cable tensioning assembly and the guiding assembly 20 are arranged on the support frame 10, the cable tensioning assembly comprises a protection mechanism 30; the cable is threaded into and out of the guiding assembly 20 and then threaded into the cable tensioning assembly, and wound on the winding disc 11 after threaded out of the cable tensioning assembly;

[0028] The cable is wound on the winding disc 11, when the motor drives the winding disc 11 to rotate, the shaft of the winding disc 11 penetrates out of the support frame 10 and is fixedly installed with the main gear 12, the winding disc 11 drives the main gear 12 to rotate, the support frame 10 is rotatably provided with the tension gear 13 on one side, the main gear 12 drives the tension gear 13 to rotate synchronously through meshing, the tension gear 13 is provided with the volute spring 14 inside, one end of the volute spring 14 is fixedly installed with the driving rod 15, the driving rod 15 has the rotational potential energy opposite to the moving direction of the cable under the driving of the deformation recovery force of the volute spring 14, the support frame 10 is provided with two groups of extrusion guide wheels 16, the two groups of extrusion guide wheels 16 are used for extruding the cable and rotating synchronously with the movement of the cable, the cable is penetrated out of the guide assembly 20 and then into the two groups of extrusion guide wheels 16, when the cable is pulled, the extrusion guide wheel 16 is rotated to make the volute spring 14 store energy, the volute spring 14 is used for driving the extrusion guide wheel 16 to rotate and tighten the cable, the rotational potential energy is transmitted to the extrusion guide wheel 16, so that the extrusion guide wheel 16 has the rotational potential energy opposite to the moving direction of the cable, the cable is pulled tightly, and then the cable is provided with a certain pre-tightening force when the cable is wound.

[0029] When the winding disc 11 rotates to wind the cable, with the increase of the winding number of the cable, the length of the single winding of the cable on the winding disc increases, under the same rotating speed of the winding disc 11, the rotating speed of the extrusion guide wheel 16 is constantly accelerated, and then the rotating proportion of the driving rod 15 and the tension gear 13 is changed, so that the increased rotating amount of the driving rod 15 increases the force storage of the volute spring 14, with the increase of the winding number of the cable, the tension provided by the extrusion guide wheel 16 increases, so that the same tightness of the inner and outer layers of the relatively thick cable can be maintained when the cable is wound.

[0030] Referring to Figure 1 and Figure 5The meshing teeth of the main gear 12 are provided with a step-out sliding block 17, and the meshing teeth of the tensioning gear 13 are provided with a step-out sliding groove 18. By setting the step-out sliding block 17, the special tooth number ratio between the main gear 12 and the tensioning gear 13 is an integer ratio of diameters, so that the step-out sliding block 17 rotates into the step-out sliding groove 18. The step-out sliding block 17 is slidably connected with the meshing teeth of the tensioning gear 13 through the step-out sliding groove 18. At this time, the main gear 12 pulls the cable through the winding disc 11, the cable drives the extrusion guide wheel 16 to rotate through friction, and the extrusion guide wheel 16 drives the driving rod 15 to rotate. At this time, the teeth on the tensioning gear 13 on both sides of the step-out sliding groove 18 slide on the surface of the step-out sliding block 17, and the tensioning gear 13 stops rotating. Then, the power of the volute spring 14 is stored, and the pre-tightening force increases with the rotation of the main gear 12. Thus, the winding provides a continuously increasing pre-tightening force. The rotation of the gears increases the rotation ratio change of the driving rod 15 and the tensioning gear 13 caused by the winding of the cable, avoids the small change range from providing sufficient tensioning force to the outer ring, further meets the greater tension of the cable of the outer ring than that of the inner ring, and facilitates the thicker cable to maintain the same tightness of the inner and outer layers during winding. Figures 3-4 The first sprocket 151 is rotatably arranged on one side of the synchronous assembly 40. The extrusion guide wheels 16 are rotatably arranged inside the synchronous assembly 40. The shafts of a group of the extrusion guide wheels 16 pass through one side of the synchronous assembly 40 and are fixedly installed with the second sprocket 161. The first sprocket 151 and the second sprocket 161 are provided with the chain 152. When the driving rod 15 rotates, the first sprocket 151 rotates, the first sprocket 151 drives the second sprocket 161 to synchronously rotate through the chain 152, the second sprocket 161 drives a group of the extrusion guide wheels 16 to synchronously rotate, and then the transmission of the rotational potential energy of the volute spring 14 between the driving rod 15 and the extrusion guide wheel 16 is completed. Then, the volute spring 14 provides the tensioning force for the cable. The first sprocket 151 transmits the rotational potential energy to the second sprocket, avoids the reverse transmission of the extrusion force of the extrusion guide wheel 16 to the driving rod 15, and then reduces the frictional resistance of the synchronous assembly 40 when moving on the driving rod 15, makes the guiding assembly 20 move more flexibly, and makes the driving rod 15 wear less.

The wire guide wheel 23 is rotatably arranged inside the synchronous assembly 40. The synchronous assembly 40 is used for synchronously moving the wire guide wheel 23 and the extrusion guide wheel 16. The cable moves to drive the wire guide wheel 23 to rotate. The wire guide wheel 23 drives the reciprocating nut 22 to rotate. The reciprocating nut 22 reciprocally moves on the surface of the reciprocating screw rod 21, so that the cable is uniformly and reciprocally wound on the winding disc 11, and the cable is prevented from being misaligned and wound.

[0032] Referring to Figures 3-4The side of the synchronous assembly 40 is fixedly provided with a anti-off cover 41, the inside of the anti-off cover 41 is fixedly provided with a bearing 42, the inside circle of the bearing 42 is fixedly connected with the side of the first sprocket 151, the first sprocket 151 is rotatably arranged in the inside of the anti-off cover 41, and the first sprocket 151 is supported by the bearing 42, so that the first sprocket 151 moves left and right with the synchronous assembly 40, and wear between the first sprocket 151 and the synchronous assembly 40 is avoided.
