Description

Technical Field

[0001] This utility model belongs to the field of wire winding technology, and in particular relates to a power wire winding drum. Background Technology

[0002] With the development of social productivity, many mechanical equipment for industrial production have emerged on the market. The use of mechanical equipment has not only greatly improved the efficiency of industrial production, but also reduced the workload of workers. When mechanical equipment is in operation, it needs a drive motor to provide driving force. The operation of the drive motor requires sufficient electrical energy, and the factory's internal electrical energy needs to be supplied by an external power plant. Since there is a distance between the factory and the external power plant, power lines are needed to transmit electrical energy, which requires the laying of power lines. To facilitate the handling of power lines, they are wound on power line spools, and the power lines are moved by moving the power line spools.

[0003] A search revealed a mobile wire winding device for the power industry in patent publication number CN220334382U, relating to the field of wire winding technology. The device includes: a movable support frame with a drum mounting mechanism at its front end and a drum support mechanism at its rear end; a handle mechanism movably mounted at the front end of the drum mounting mechanism; and a rotatable wire drum mechanism fitted onto the drum mounting mechanism, with one end facing away from the drum mounting mechanism movably mounted on the drum support mechanism. With one end of the wire drum mechanism mounted on the drum mounting mechanism and the other end on the drum support mechanism, both ends of the wire drum mechanism have mechanisms to support its rotation, providing stable support and preventing instability caused by the wire drum mechanism being suspended in mid-air. Furthermore, the movable support frame facilitates movement and transport by workers, saving them physical labor.

[0004] However, power cable winding drums still have the following drawbacks in actual use:

[0005] 1. The power wire winding drum consists of a support frame, wheels, a drum, and limiting discs. Limiting discs are fixed to both ends of the drum. A convex shaft fixed to the side wall of the limiting disc is rotatably connected to the side wall of the support frame. Wheels are installed on the outer wall of the support frame. When the drum rotates, it can wind or unwind the power wire. However, the limiting discs (i.e., the baffles on both sides of the winding drum) physically prevent the wire from slipping, and the wire inevitably comes into contact with their inner surfaces during winding. Especially at the beginning and end of winding, the wire slides tightly against the surface of the limiting disc under tension, generating sliding friction. Since the limiting disc is made of a hard material, this increases the friction between the power wire and the limiting disc, and may even cause wear on the power wire.

[0006] 2. During the rotation of the drum, the power wire is wound up or unwound. At the same time, the limit plate rotates with the drum. However, the limit plate is only supported by the convex shaft, which is too weak. When more and more wire is wound, the drum will fall off due to excessive weight.

[0007] To address these issues, we provide a power cable winding spool. Utility Model Content

[0008] The purpose of this utility model is to provide a power wire winding cylinder, which reduces the friction between the wire and the movable disc by setting a winding assembly, thus avoiding wire wear, and provides a load-bearing component, a guide rail and ball bearings to support the load. At the same time, the ball bearings can assist the rotation of the limiting disc, thereby solving the technical problems mentioned in the background art.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model relates to a power wire winding drum, comprising a support frame, a winding assembly on the upper surface of the support frame, the winding assembly including limiting discs symmetrically fixed to both ends of the drum, a convex shaft fixed to the outer wall of the limiting disc, a rotating hole on the side wall of the support frame, the convex shaft being rotatably connected inside the rotating hole, grooves arranged in a ring array on the inner wall of the limiting disc, a movable disc symmetrically sleeved on the peripheral side wall of the drum, a sleeve fixed in a ring array on the inner wall of the movable disc, a return spring fixed to the end of the sleeve and connected to the inner wall of the groove; a load-bearing assembly on the upper surface of the support frame, the load-bearing assembly including a guide rail frame symmetrically connected to the upper surface of the support frame, a ball bearing on the inner bottom of the guide rail frame, and the limiting discs supported on the ball bearing.

[0011] The present invention is further configured such that wheels are installed on the side wall of the bracket, and the four wheels are distributed in a rectangular array.

[0012] The present invention is further configured such that the internal part of the bracket is fixed with reinforcing ribs, the two sets of reinforcing ribs are symmetrically distributed, and each set of reinforcing ribs has two ribs.

[0013] The present invention is further provided with a rubber pad on the side wall of the movable disc, the rubber pad being located on the side away from the limiting disc.

[0014] The present invention is further configured such that a guide rod is fixedly connected to the inner wall of the groove, the guide rod is located inside the reset spring, and the outer diameter of the guide rod is smaller than the inner diameter of the sleeve.

[0015] The present invention is further configured such that the cross-section of the guide rail frame is an arc-shaped groove structure, and the upper surface of the ball does not exceed the upper surface of the guide rail frame.

[0016] The present invention is further configured such that pads are symmetrically fixed to the lower surface of the guide rail frame, and the lower surface of the pads is fixed to the upper surface of the bracket.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting up a winding assembly, allows the winding drum to rotate to take in and unwind the wire, and the limiting disc to rotate accordingly. When the wire squeezes the movable disc, the return spring is compressed, and the movable disc moves closer to the limiting disc, which helps to reduce the squeezing force between the wire and the movable disc, reduce the friction between the wire and the movable disc, avoid wire wear, prevent electric shock accidents, and increase safety.

[0019] 2. By setting up a load-bearing component, the ball rolls inside the guide rail frame when the limiting plate rotates. The addition of the guide rail frame and the ball provides support and load-bearing function, while the ball assists the limiting plate in rotating. Attached Figure Description

Detailed Implementation

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 1 The present invention is a power wire winding drum, including a bracket 1 and a wheel 101. The wheel 101 is used to reduce the friction between the bracket 1 and the ground, and to facilitate the adjustment of the position of the bracket 1 by means of the wheel 101.

[0030] Specifically, wheels 101 are installed on the side wall of the bracket 1, and the four wheels 101 are arranged in a rectangular array; furthermore, reinforcing ribs 102 are fixed inside the bracket 1, and two sets of reinforcing ribs 102 are symmetrically distributed, with two reinforcing ribs 102 in each set.

[0031] The operation process of this embodiment is as follows: push the bracket 1, the wheel 101 moves on the ground, and move the bracket 1 to the working position.

[0032] Example 2

[0033] Please see Figure 1 , Figure 3 and Figure 4 Based on the first specific embodiment, a winding assembly 2 is provided. The winding assembly 2 includes a drum 201, a limiting disc 202, a groove 202a, a movable disc 203, a sleeve 203a, and a return spring 203b. The drum 201 is used to wind up and unwind the wire. The limiting disc 202 prevents the wire from detaching from the drum 201. The use of the return spring 203b makes the distance between the movable disc 203 and the limiting disc 202 adjustable, adjusting the friction between the wire on the drum 201 and the movable disc 203, avoiding wear on the outer wall of the wire by the movable disc 203, preventing electric shock accidents, and increasing safety.

[0034] Specifically, both ends of the drum 201 are fixedly connected to a limiting disk 202. A convex shaft 201c is fixedly connected to the outer wall of the limiting disk 202. A rotating hole 103 is opened on the side wall of the bracket 1. The convex shaft 201c is rotatably connected inside the rotating hole 103. A movable disk 203 is symmetrically sleeved on the peripheral side wall of the drum 201. A groove 202a is opened in an annular array on the inner wall of the limiting disk 202. A sleeve 203a is fixedly connected in an annular array inside the movable disk 203. A return spring 203b is fixedly connected to the end of the sleeve 203a. The end of the return spring 203b is connected to the inner wall of the groove 202a.

[0035] Furthermore, a guide rod 202b is fixed to the inner wall of the groove 202a. The guide rod 202b is located inside the return spring 203b. The outer diameter of the guide rod 202b is smaller than the inner diameter of the sleeve 203a. A rubber pad 204 is provided on the side wall of the movable disk 203. The rubber pad 204 is located on the side away from the limiting disk 202.

[0036] The operation process of this embodiment is as follows: the limiting disc 202 or the drum 201 rotates under the influence of rotational force. When the drum 201 rotates clockwise, it winds up the wire; when the drum 201 rotates counterclockwise, it unwinds the wire. During the winding and unwinding process, when the wire presses against the movable disc 203, the movable disc 203 moves towards the limiting disc 202, and the return spring 203b is compressed. Since the movable disc 203 is in a movable state, the pressure between the wire and the movable disc 203 is reduced. The reduced pressure leads to a decrease in friction, thereby reducing the friction between the wire and the movable disc 203. When the return spring 203b is compressed to a certain extent (at this time, the return spring 203b is not fully compressed), the return spring 203b applies a reaction force to the movable disc 203, pushing the movable disc 203 away from the limiting disc 202. At the same time, it pushes the wire away from the movable disc 203 until the movable disc 203 returns to its initial position.

[0037] Example 3

[0038] Please see Figure 1 and Figure 2 Based on specific embodiments one and two, a load-bearing component 3 is provided. The load-bearing component 3 includes a guide rail frame 301 and ball bearings 302. The guide rail frame 301 serves to assist in supporting the limiting plate 202, because as the wires become more and more coiled, the overall load increases, and the support between the convex shaft of the limiting plate 202 and the bracket 1 is not enough. At the same time, the guide rail frame 301, together with the ball bearings 302, assists the limiting plate 202 in rotating.

[0039] Specifically, the upper surface of the bracket 1 is symmetrically connected with a guide rail 301, and the inner bottom of the guide rail 301 is provided with a ball bearing 302, and the limiting plate 202 is supported on the ball bearing 302.

[0040] Furthermore, the guide rail frame 301 has an arc-shaped groove structure in its cross section. The upper surface of the guide rail frame 301 is higher than the upper side of the ball bearing 302. A pad 301a is fixedly connected to the lower surface of the guide rail frame 301, and the pad 301a is fixedly connected to the upper surface of the bracket 1.

[0041] The operation process of this embodiment is as follows: when the drum 201 rotates to wind and unwind the wire, the limiting disk 202 rotates accordingly, and the ball bearing 302 rolls on the guide rail frame 301.
