Abstract
Description
Technical Field
[0001] The utility model relates to the field of overhead conductor stranding devices. More specifically, the utility model relates to a novel anti-jumping and anti-backing device for overhead conductors. Background Art
[0002] During the production of overhead conductors, a wire splitting device and a pre-twisting device are used to control the stranding quality and tightness of the conductors. The position of the traditional wire splitting device is generally fixed or semi-fixed. When adjusting, it is restricted by the distance between the shaft barrels and the position of the base. The conductors are split through the wire threading wheels on the wire splitting disc. However, a certain distance needs to be reserved between the fixed areas of the single-wire threading wheels to adjust the pre-twisting distance. If the distance is too close, it will affect the stranding quality of the finished conductors. Therefore, during the high-speed rotation of the stranding cage, under the action of centrifugal force, there is a certain probability that the single wires will be thrown out of the guide wheels, resulting in phenomena such as back stranding and wire jumping, seriously affecting the product quality. Summary of the Utility Model

[0010] The utility model has at least the following beneficial effects:
[0011] The utility model provides a novel device for preventing wire jumpers and back strands in overhead conductors. An open distribution plate is added to the end of the central axis close to the paralleling mold. Each groove of the open distribution plate has 0-1 single wires. A convex tooth is formed between two adjacent grooves to separate the single wires in the two grooves, which can effectively prevent back strands. The open grooves can reduce the time workers spend threading wires and improve work efficiency. The buffer pads in the grooves are used to buffer the passing single wires to avoid scratching the surface of the single wires.

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.
[0018] It should be noted that, unless otherwise specified, the experimental methods described in the following implementation schemes are all conventional methods, and the reagents and materials, unless otherwise specified, can all be obtained through commercial channels; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present invention.
[0019] As Figures 1 to 4 As shown, the present invention provides a novel anti-jumping and anti-back-twisting device for overhead conductors, including: a central shaft 1, with a wire combining die 7 arranged at one end thereof at intervals; a closed wire distributing disc 2 and an open wire distributing disc 5 are sleeved on the central shaft 1 at intervals from the central shaft 1 to the direction of the wire combining die 7; a circle of limiting belts 4 is arranged between the closed wire distributing disc 2 and the open wire distributing disc 6; the cross-sectional shape of the open wire distributing disc 5 is in a dish shape, which includes a disc body 51 and a forward-inclined part 52 fixedly sleeved on the outer periphery of the disc body 51, and the forward-inclined part 52 faces the wire combining die 4 and inclines towards the center of the disc body 51; a plurality of grooves are spaced apart on the outer periphery of the forward-inclined part 51, and buffer pads 6 are detachably connected in the grooves; a plurality of wire threading wheels 3 are arranged on the closed wire distributing disc 2.
[0020] In this technical solution, the closed wire distributing disc is the traditional wire distributing disc used in the conventional stranding of overhead conductors. The present invention adds the open wire distributing disc 5 at the end of the central shaft 1 close to the wire combining die 7. Each groove of the open wire distributing disc 5 has 0 - 1 single wires, and a convex tooth is formed between adjacent two grooves to isolate the single wires in the two grooves, which can well achieve the anti-back-twisting effect; the open grooves can reduce the wire threading time of workers and improve work efficiency. The open wire distributing disc can be customized with different groove numbers according to actual needs to adapt to the production of each stranding cage. The buffer pads 6 in the grooves are used to buffer the passing single wires to avoid scratching the surface of the single wires, and the detachable design facilitates the workers to quickly replace them when they are worn. The function of the limiting belt 4 is to limit the position of the single wires to prevent the single wires from being thrown out of their original positions along with the rotation of the stranding cage during the high-speed operation of the stranding machine, resulting in wire jumping and affecting the surface quality of the overhead conductor. Each single wire passes through the wire threading wheels 3 on the closed wire distributing disc 2, then passes through the limiting belt, and then passes through the corresponding grooves of the open wire distributing disc 5, and finally enters the wire combining die 7.
[0021] In another technical solution, the buffer pad 6 is a nylon pad with a saddle-shaped structure. Further, threaded counterbores are provided on the buffer pad 6, and threaded blind holes corresponding to the threaded counterbores on each buffer pad 6 are provided on the forward inclination part 52. During actual use, the buffer pad 6 can be fixed in the groove on the forward inclination part 52 by an internal hexagonal screw. The threaded counterbores can embed the nut of the internal hexagonal screw in the buffer pad 6, preventing the internal hexagonal screw from contacting the single wire and avoiding scratching the surface of the single wire.
[0022] In another technical solution, the limiting belt 4 is a nylon belt, and its two ends are connected by buckles; the diameter of the circle formed after the two ends of the limiting belt 4 are connected is between the diameters of the closed wire distributing disc 2 and the open wire distributing disc 5 on both sides thereof. Using a nylon belt, because it has certain elasticity and tightening force, and its own mass is small and the centrifugal force is small, during the high-speed rotation process, it can play a role in tightening and stabilizing the aluminum wire and copper wire with higher mass and larger centrifugal force, avoiding the single wire being thrown out of its original position along with the rotation of the cage during the high-speed operation of the stranding machine, resulting in quality problems such as wire jumping or back twisting.
[0023] In another technical solution, the included angle between the center line of the groove and the center line of the central axis is 15° to 30°, that is Figure 1 α takes a value of 15° to 30°. Through the appropriate inclination angle of the forward inclination part 52, the single wire is prevented from being bent in the groove.
[0024] In another technical solution, a plurality of the closed wire distributing discs 2 are provided, and the plurality of closed wire distributing discs 2 are arranged at intervals. As Figure 1 shown, each single wire passes through the wire threading wheels 3 on each closed wire distributing disc 2 in sequence and then enters the limiting belt 4, and then passes through the corresponding groove on the open wire distributing disc, and finally enters the wire merging die 7. Preferably, when the single wire passes through each closed wire distributing disc, it passes through the corresponding wire threading wheels 3 alternately up and down.
[0025] Although the implementation schemes of the present invention have been disclosed above, it is not limited to only the applications listed in the description and implementation modes. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, other modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples here.
