Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a device for hot-melt forming of insulation layer of power cable fusion joint. Background Technology

[0002] With the continuous development of the power industry, power cables have been widely used in various power transmission scenarios. In the process of laying and maintaining power cables, the connection between cables is a key link, and the quality of the fusion joint directly affects the stability and safety of power transmission.

[0003] Currently, in traditional cable splice insulation layer hot-melt forming devices, the cable is prone to displacement during the hot-melt process, which may lead to uneven distribution of insulation material and internal voids during hot-melt.

[0004] In some existing technologies, most power cable fusion splice insulation layer hot-melt forming devices lack effective positioning and fixing of the cable during use. This may lead to problems such as non-adhesion between the hot-melt insulation material and the cable, and internal gaps, which will affect the quality of the final product. Utility Model Content

[0005] The main purpose of this utility model is to provide a hot-melt forming device for the insulation layer of power cable fusion joints. This device can effectively solve the problem that most existing hot-melt forming devices for the insulation layer of power cable fusion joints lack a device for effectively positioning and fixing the cable during use. This may lead to problems such as the insulation material not adhering to the cable after hot-melt forming, and gaps inside, which will affect the quality of the final product.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A device for hot-melt forming of insulation layer of power cable fusion joint includes a cable mechanism. Clamping mechanisms are symmetrically installed on the outer surface of the cable mechanism. Each clamping mechanism has a front-to-back adjustment mechanism at its bottom, and a left-to-right adjustment mechanism is installed at the bottom of both front-to-back adjustment mechanisms.

[0008] Preferably, the left and right ends of the left and right adjustment mechanism are equipped with supporting base frames, the front end of the cable mechanism is provided with a placement frame, and the top of the placement frame is engaged with a hot melt gun.

[0009] Preferably, the cable mechanism includes two cables, and the opposite ends of the two cables are provided with a fusion joint.

[0010] Preferably, each of the two clamping mechanisms includes two clamps, and the outer surfaces of the two cables are respectively engaged with the opposite sides of the two clamps on the same side; the two clamps on the same side are symmetrically arranged front and back, and the upper sides of the two clamps are symmetrically fixedly connected with limiting telescopic rods, and the lower sides of the two clamps are symmetrically slidably connected with limiting telescopic rods; the outer surfaces of the four limiting telescopic rods on the same side and at the same end are jointly equipped with clamps; the opposite sides of the clamps are symmetrically fixedly connected with elastic connecting pieces, and a spring piece is provided in the middle of the opposite sides of the clamps.

[0011] Preferably, support plates are fixedly connected to opposite sides of the outer surfaces of the two clamps located on the same side, and a support frame is fixedly connected to the bottom of the support plates.

[0012] Preferably, both of the front and rear adjustment mechanisms include adjustment slides, and the front and rear ends of the outer surfaces of the two adjustment slides are fixedly connected to support side plates, and the support frame is slidably connected to the outer surface of the adjustment slide.

[0013] Preferably, the left and right adjustment mechanism includes a base, and movable seats are symmetrically slidably connected to the front and rear sides of the inner surface of the base. The bottom of the two movable seats located at the same end is fixedly connected to the second support frame. The upper sides of the opposite faces of the two second support frames located on the same side are respectively fixedly connected to the lower sides of the opposite faces of the two support side plates on the same side.

[0014] Preferably, the inner surfaces of the two movable seats located at the same end are connected by a bidirectional threaded rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This device, through its designed clamping mechanism, works in conjunction with the front and rear adjustment mechanisms to facilitate quick assembly and disassembly of the cable assembly. By clamping and fixing the cable assemblies at both ends through two clamping mechanisms, the positions of the two cable assemblies can be accurately positioned, which helps to improve the accuracy of the weld joint forming. This ensures that the insulation layer is evenly distributed during hot melting, avoiding problems such as uneven insulation thickness and internal gaps caused by cable position deviations. Therefore, it helps to improve the accuracy of the weld joint forming, ensuring the electrical performance and service life of the power cable.

[0017] 2. This device, through its designed left and right adjustment mechanism, accommodates power cables of different models and specifications, whose core diameter, insulation thickness, and other parameters vary.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1, as Figure 1As shown, a hot-melt forming device for insulation layer of power cable fusion joint includes a cable mechanism 1. Clamping mechanisms 2 are symmetrically installed on the outer surface of the cable mechanism 1. Both clamping mechanisms 2 are provided with front-to-back adjustment mechanisms 3 at their bottoms. Both front-to-back adjustment mechanisms 3 are provided with left-to-right adjustment mechanisms 4 at their bottoms.

[0027] In this embodiment, the power cable fusion splice insulation layer hot melt forming device is placed in a suitable working position to ensure that the support base 5 stably supports the entire device. The two cables 101 are clamped and fixed by the clamping mechanism 2 respectively. The distance between the two clamping mechanisms 2 can be adjusted by the front and rear adjustment mechanism 3, and the distance between the two cables 101 can be adjusted by the left and right adjustment mechanism 4.

[0028] For details, please refer to Figure 1 In this embodiment, the left and right ends of the left and right adjustment mechanism 4 are equipped with support bases 5, the front end of the cable mechanism 1 is provided with a placement frame 7, and the top of the placement frame 7 is connected to a hot melt gun 6.

[0029] Further reference Figure 1 and Figure 2 In this embodiment, the cable mechanism 1 includes two cables 101, and the opposite ends of the two cables 101 are provided with a fusion joint 102.

[0030] The hot melt gun 6 is secured to the placement frame 7, the power supply to the hot melt gun 6 is turned on, and it is preheated to a suitable temperature. The hot melt gun 6 is held and used to heat the fusion joint 102 of the cable 101, so that the insulation material is melted. Because the cable 101 has been accurately positioned and appropriately adjusted in the early stage through the clamping mechanism 2 and the front and rear adjustment mechanism 3, and the left and right adjustment mechanism 4 is adapted to the cable specifications, the insulation layer can be evenly distributed at the fusion joint 102 during hot melting, avoiding problems such as uneven insulation thickness and internal gaps caused by cable position deviation. After heating is completed, wait for the insulation material at the fusion joint 102 to cool and solidify to form an insulation layer that meets the requirements. The hot melt forming operation of the insulation layer of the power cable fusion joint is then completed.

[0031] Further reference Figure 1 , Figure 2 and Figure 3 In this embodiment, each of the two clamping mechanisms 2 includes two clamps 201, and the outer surfaces of the two cables 101 are respectively engaged and connected to the opposite sides of the two clamps 201 on the same side; the two clamps 201 on the same side are symmetrically arranged front and back, and the upper sides of the two clamps 201 are symmetrically fixedly connected to the limiting telescopic rods 202, and the lower sides of the two clamps 201 are symmetrically slidably connected to the limiting telescopic rods 202;

[0032] Further reference Figure 1 and Figure 3In this embodiment, the outer surfaces of the four limiting telescopic rods 202 located on the same side and at the same end are jointly equipped with clamps 205. Elastic connecting pieces 204 are symmetrically fixed to the opposite sides of clamps 1 201 and clamps 205. A spring piece 203 is provided in the middle of the opposite sides of clamps 1 201 and clamps 205. Support plates 206 are fixedly connected to the opposite sides of the outer surfaces of the two clamps 205 located on the same side. Support frame 207 is fixedly connected to the bottom of support plate 206.

[0033] Two cables 101 are placed on the clamping mechanisms 2 on both sides. Two clamps 201 are arranged as a group, symmetrically arranged on the same side of the cables 101. The cables 101 are clamped between the opposite sides of the two clamps 201. During the installation of the cables 101, the limiting telescopic rod 202 can be adjusted according to the diameter of the cables 101 to make the clamps 201 fit the cables 101 better. At the same time, the spring pieces 203 and elastic connecting pieces 204 on the opposite sides of the clamps 201 and clamps 205 provide a certain elastic force. Through such clamping mechanism 2, the cables 101 can be quickly installed and fixed.

[0034] Two clamping mechanisms 2 respectively fix the cable mechanisms 1 at both ends, so as to achieve accurate positioning of the two cables 101, ensuring the precise relative position of the cables 101, and laying the foundation for the uniform forming of the insulation layer at the subsequent fusion joint 102.

[0035] Further reference Figure 1 , Figure 4 and Figure 5 In this embodiment, both front and rear adjustment mechanisms 3 include adjustment slides 301. Support side plates 302 are fixedly connected to the front and rear ends of the outer surfaces of the two adjustment slides 301. Support frame 207 is slidably connected to the outer surface of the adjustment slides 301.

[0036] By using the designed clamping mechanism 2, which works in conjunction with the front and rear adjustment mechanism 3, the cable mechanism 1 can be quickly assembled and disassembled. By clamping and fixing the two ends of the cable mechanism 1 with the two clamping mechanisms 2 respectively, the positions of the two cable mechanisms 1 can be accurately positioned, which helps to improve the forming accuracy of the fusion joint 102 to a certain extent. This ensures that the insulation layer is evenly distributed during hot melting, avoiding problems such as uneven insulation thickness and internal gaps caused by cable position deviation. Thus, it helps to improve the forming accuracy of the fusion joint 102 to a certain extent, ensuring the electrical performance and service life of the power cable.

[0037] Example 2: Based on Example 1, this example adds a left-right adjustment mechanism 4 for electrically adjusting the relative distance between the two cables 101. By setting the left-right adjustment mechanism 4, the distance between the two cable mechanisms 1 can be flexibly adjusted, thereby achieving the effect of adapting to the splicing requirements of cables of different specifications.

[0038] For details, please refer to Figure 1 , Figure 5 and 6 In this embodiment, the left and right adjustment mechanism 4 includes a base 401. The front and rear sides of the inner surface of the base 401 are symmetrically connected to movable seats 402. The bottom of the two movable seats 402 located at the same end is fixedly connected to the support frame 403. The upper side of the opposite face of the two support frames 403 located on the same side is fixedly connected to the lower side of the opposite face of the two support side plates 302 on the same side.

[0039] Further reference Figure 5 and Figure 6 In this embodiment, the inner surfaces of the two movable seats 402 located at the same end are connected by a bidirectional threaded rod 404. A drive box 405 is installed on the front side of the right end of the left and right adjustment mechanism 4. A control switch 406 is installed on the right end of the drive box 405. The right end of the bidirectional threaded rod 404 located at the front end is rotatably connected to the output end of the drive box 405.

[0040] According to the specifications of the cable to be fused, the drive box 405 of the left and right adjustment mechanism 4 is started by the control switch 406. The drive motor in the drive box 405 drives the front bidirectional threaded rod 404 to rotate. The cooperation between the rear bidirectional threaded rod 404 and the front end allows the cable mechanism 1 to maintain a relatively parallel state when moving.

[0041] Since the two movable seats 402 located at the same end are threadedly connected to the bidirectional threaded rod 404, and the base 401 plays a limiting sliding role on the movable seats 402, the rotation of the bidirectional threaded rod 404 causes the two movable seats 402 to move relative to each other or away from each other in the left and right directions within the base 401. The movable seats 402 drive the support side plate 302 of the front and rear adjustment mechanism 3 to move through the support frame 2 403, thereby adjusting the distance between the two cable mechanisms 1 to adapt to the welding requirements of cables of different specifications.

[0042] The left and right adjustment mechanism 4 is designed to accommodate the different parameters of power cables of different models and specifications, such as core diameter and insulation thickness. The drive box 405 drives the bidirectional threaded rod 404 at one end. The rotation of the bidirectional threaded rod 404 can adjust the distance between the two cable mechanisms 1. By flexibly adjusting the distance between the two cable mechanisms 1, the needs of splicing cables of different specifications can be met. The electric adjustment method makes it easier for operators to place, fix and perform subsequent operations on the cables, which reduces the difficulty of operation and improves work efficiency to a certain extent.

[0043] The drive box 405 in this solution includes an outer mounting box, a drive motor, and a controller. The drive motor and controller are installed inside the outer mounting box. The controller here can be a motor controller that is compatible with the drive motor in the prior art, and can control the switching and rotation speed of the drive motor.

[0044] Both adjusting slides 301 in this solution include adjusting slides, springs, adjusting tooth plates, and movable seats. The movable seat has a locking tooth installed on the outer side of the end near the inside of the adjusting slide. When the movable seat moves, the spring is compressed and extends, thereby achieving the movement effect of the movable seat. When the movable seat stops moving, the spring rebounds elastically and engages with the locking tooth on the outer side of the movable seat through the locking tooth at the adjusting tooth plate, thereby achieving the effect of limiting and fixing the movable seat. Thus, the movable seat after the position is adjusted can be fixed in place. The movable seat is installed and fixed with the support frame 207. The position of the support frame 207 can be adjusted by adjusting the height of the movable seat.

[0045] In this design, the base 401 is equipped with spiral steel strip screw protective sleeves on the outer side near the two bidirectional threaded rods 404 to prevent debris from entering the thread groove and ensure normal rotation and processing of the machine.

[0046] Since the above devices are all very mature products in the prior art, they will not be described in detail in this application.

[0047] It should be noted that the specific installation method, circuit connection method and control method of the drive box 405 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
