A cable covering cooling aid

Abstract

This utility model discloses a cable wrapping cooling auxiliary tool, including: a crossbar, a first clamping arm fixedly mounted in the middle of the crossbar, an adjusting component adjustablely mounted on the crossbar via an installation mechanism and with an adjustable distance from the first clamping arm, and a second clamping arm mounted on the adjusting component via a first hinge shaft perpendicular to the crossbar and opposite to the first clamping arm. Each of the first and second clamping arms has a handle fixedly connected to its end away from the crossbar. The user holds the handles, causing the second clamping arm to rotate closer to the first clamping arm to clamp the end of the cable. Placing the crossbar horizontally on the two top sides of the cooling water tank prevents water from entering the cable end. Since the cable itself moves forward during continuous extrusion, only the direction of the cable end needs to be controlled. This tool is simple to use and labor-saving. After traction is completed, rotating the second clamping arm away from the first clamping arm quickly releases the cable end without affecting the continuous manufacturing of the cable.

Description

Technical Field

[0001] This utility model relates to the technical field of cable manufacturing, specifically to a cable sheathing cooling auxiliary tool. Background Technology

[0002] In cable manufacturing, extrusion and cooling are continuous and crucial core processes that directly determine the quality and performance of the insulation, sheath, or shielding layers of cables (such as power cables, communication cables, and data cables).

[0003] Coating extrusion is the process of uniformly, continuously, and tightly wrapping a specific material (such as PVC, XLPE cross-linked polyethylene, PE polyethylene, PP polypropylene, TPE thermoplastic elastomer, rubber, etc.) onto a conductor (copper, aluminum, etc.) or cable core (a conductor bundle that has already been insulated).

[0004] The cooling process commonly used is water bath cooling, which rapidly cools and solidifies the polymer layer that has just been extruded from the die and is in a molten state, thereby obtaining stable geometric dimensions and shapes. Controlling the cooling rate helps to reduce uneven shrinkage and internal stress caused by temperature gradients, and prevents subsequent deformation and cracking. For materials such as PE and PP, the cooling rate affects the crystallinity and crystal morphology, which in turn affects the density, hardness, toughness, chemical resistance, and electrical properties of the final product.

[0005] After the cable end passes through the extruder, it needs to be manually pulled through a cooling water tank. During this pulling process, the cable end needs to be tilted upwards above the water surface to prevent water from entering and affecting subsequent use. Therefore, the operator needs to continuously lift the cable end during the cooling water tank process. However, when the cable diameter is greater than 4cm, lifting the cable end will cause local bending. The internal stress generated by the bending will require the operator to resist the downward force generated by the cable as it returns to its flat state when pulling it up. The cooling water tank for medium-sized cables is generally 10-40m long. Because the operator holds the cable end for too long, there is a risk of loss of strength or operational error, which may lead to water entering the cable end. Therefore, it is necessary to design a cable wrapping and cooling auxiliary tool. Utility Model Content

[0006] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the problem that the long length of the cooling water tank in the prior art makes it easy to have the risk of slippage or error during operation.

[0007] To achieve the above objectives, this utility model provides a cable wrapping and cooling auxiliary tool, comprising: a crossbar, a first clamping arm fixedly mounted in the middle of the crossbar, an adjusting member adjustablely mounted on the crossbar via an installation mechanism and with an adjustable distance from the first clamping arm, and a second clamping arm mounted on the adjusting member via a first hinge shaft perpendicular to the crossbar and opposite to the first clamping arm, wherein a handle is fixedly connected to the end of the first and second clamping arms away from the crossbar.

[0008] Preferably, a clamping plate is mounted on the opposite side of the first clamping arm and the second clamping arm, and a plurality of cone-shaped portions distributed in a matrix are protruding from the clamping plate.

[0009] Preferably, both ends of the crossbar are fixedly connected to a limiting disc with a diameter larger than that of the crossbar.

[0010] Preferably, the crossbar has a mounting portion protruding from the middle and extending in the same direction as the mounting portion, and sleeves located on both sides of the mounting portion are rotatably fitted onto the crossbar, the outer diameter of the sleeves being smaller than the outer diameter of the limiting disc.

[0011] Preferably, a strip-shaped through groove is provided through the mounting part in the same length direction. The mounting component includes an L-shaped plate and a rotating plate that is hinged to one end of the L-shaped plate through a second hinge shaft parallel to the crossbar. The mounting mechanism includes mounting bolts that can pass through the end of the L-shaped plate away from the second hinge shaft, the strip-shaped through groove and the rotating plate in sequence, as well as nuts threaded onto the end of the mounting bolts.

[0012] Preferably, a plurality of slots are recessed on one side of the strip-shaped through groove and spaced apart along the length direction, and a block portion protruding from the L-shaped plate is provided that can be inserted into the corresponding slot.

[0013] According to the above technical solution, the cable sheathing cooling auxiliary tool provided by this utility model has the following beneficial effects during use:

[0014] Firstly, the user holds a pair of handles, causing the second clamping arm to rotate close to the first clamping arm to clamp the end of the cable. The two ends of the crossbar are placed horizontally on the two top sides of the cooling water tank, which can prevent water from entering the cable end. As the cable is continuously squeezed out, the cable end itself will move forward. Therefore, it is only necessary to control the direction of the cable end. This tool is simple to use and saves effort.

[0015] Secondly, after the traction is completed, the second clamping arm can be rotated away from the first clamping arm to quickly release the end of the cable without affecting the continuous manufacturing of the cable.

[0016] Thirdly, the position between the adjusting component and the first clamping arm can be adjusted through the installation mechanism, which not only improves the applicability of the tool, but also allows the user to hold the pair of handles in a comfortable way, avoiding the inconvenience caused by the distance between the pair of handles being too far apart.

[0017] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0025] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0026] like Figure 1-3As shown, a cable wrapping cooling auxiliary tool includes: a crossbar 1, a first clamping arm 2 fixedly mounted in the middle of the crossbar 1, an adjusting member 3 adjustablely mounted on the crossbar 1 via an installation mechanism and with an adjustable distance from the first clamping arm 2, and a second clamping arm 5 mounted on the adjusting member 3 via a first hinge shaft 4 perpendicular to the crossbar 1 and opposite to the first clamping arm 2. A handle 6 is fixedly connected to the end of the first clamping arm 2 and the second clamping arm 5 away from the crossbar 1.

[0027] In the above technical solution, after the end of the cable passes through the coating extruder, the end of the cable is clamped by the first clamping arm 2 and the second clamping arm 5. The user holds a pair of handles 6, so that the second clamping arm 5 rotates close to the first clamping arm 2 to clamp the end of the cable. The two ends of the crossbar 1 are placed horizontally on the two top sides of the cooling water tank, which can prevent water from entering the end of the cable. Since the cable is continuously extruded, the end of the cable itself will move forward. Therefore, it is only necessary to control the direction of the end of the cable. This tool is simple to use and saves effort.

[0028] Since the cable needs to be coiled after its surface is air-dried in the cooling water tank, after the traction is completed, the second clamping arm 5 is driven away from the first clamping arm 2 to rotate, which can quickly loosen the end of the cable for coiling. It can quickly clamp and loosen the end of the cable without affecting the continuous manufacturing of the cable.

[0029] When the diameter of the target cable is changed, the position between the adjusting part and the first clamping arm 2 can be adjusted through the installation mechanism. This not only improves the applicability of the tool, but also allows the user to hold the pair of handles 6 in a comfortable way, avoiding the inconvenience caused by the distance between the pair of handles 6 being too far apart.

[0030] In a preferred embodiment of the present invention, clamping plates 7 are mounted on opposite sides of the first clamping arm 2 and the second clamping arm 5, and a plurality of cone-shaped portions 8 are protruding from the clamping plates 7 and arranged in a matrix.

[0031] In the above technical solution, the conical part 8 can penetrate into the rubber sleeve of the cable end to increase the clamping force. In actual use, the rubber sleeve of the cable end itself will be removed to connect with the ends of other cables. Therefore, setting the conical part 8 will not affect the actual use of the cable and can improve the clamping force.

[0032] In a preferred embodiment of this utility model, both ends of the crossbar 1 are fixedly connected to a limiting disc 9 with a diameter larger than that of the crossbar 1.

[0033] In the above technical solution, a pair of limiting discs 9 are located on the outside of the cooling water tank, which can make the end of the crossbar 1 slide off the top side of the cooling water tank, further improving the ease of use.

[0034] In a preferred embodiment of the present invention, a mounting portion 10 of the same length direction is provided protruding from the middle of the crossbar 1, and sleeves 11 located on both sides of the mounting portion 10 are rotatably sleeved on the crossbar 1, the outer diameter of the sleeves 11 being smaller than the outer diameter of the limiting disc 9.

[0035] In the above technical solution, the sleeve 11 can roll on the crossbar 1, thereby reducing the friction between the crossbar 1 and the top side of the cooling water tank during the movement of the crossbar 1 and improving the smoothness of the movement of the crossbar 1; the limiting plate 9 can not only prevent the crossbar 1 from slipping off the top side of the cooling water tank, but also play an installation role for the sleeve 11.

[0036] In a preferred embodiment of the present invention, a strip-shaped through groove 12 is provided through the mounting part 10 along the same length direction. The mounting component includes an L-shaped plate 13 and a rotating plate 15 that is hinged to one end of the L-shaped plate 13 via a second hinge shaft 14 parallel to the crossbar 1. The mounting mechanism includes a mounting bolt 16 that can pass sequentially through the end of the L-shaped plate 13 away from the second hinge shaft 14, the strip-shaped through groove 12 and the rotating plate 15, and a nut threaded onto the end of the mounting bolt 16.

[0037] In the above technical solution, when it is necessary to adjust the distance between the adjusting member 3 and the first clamping arm 2, loosen the nut and remove it, so that the rotating plate 15 can rotate. The rotating plate 15 and the L-shaped plate 13 will not form a clamping force on the mounting part 10, and the position of the adjusting member 3 can be adjusted. Then, assemble the nut on the end of the mounting bolt 16 and tighten it, so that the rotating plate 15 and the L-shaped plate 13 tightly clamp the two sides of the mounting part 10.

[0038] In a preferred embodiment of the present invention, a plurality of slots 17 are recessed on one side of the strip-shaped through groove 12 and spaced apart along the length direction, and a block portion 18 protrudes from the L-shaped plate 13 and can be inserted into the corresponding slot 17.

[0039] In the above technical solution, the locking block 18 is inserted into the locking slot 17, which can further improve the stability of the adjusting member 3 when it is fixed.

[0040] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0041] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0042] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
