Description

Technical Field

[0001] The invention belongs to the technical field of power equipment maintenance, and in particular relates to a semi-automatic cable heat shrink sealing device. Background Art

[0002] In the process of power transmission, cable sealing is an important part to ensure the normal operation of the cable. If the cable cutout is not properly sealed during storage or transportation, foreign substances such as moisture and dust may enter the cable, causing a series of problems, such as moisture inside the cable, damage to the insulation layer, corrosion of metal parts, etc. These problems will lead to degradation of cable performance, shortened service life, and may even cause serious accidents such as cable aging, short circuit or fire, posing a threat to the safe operation of the power system.

[0003] At present, the commonly used cable plugging methods on the market mainly include manually operated hot air guns combined with heat shrink tubing for plugging. Although these traditional methods are simple and easy to use, they have the following main disadvantages:

[0004] Low operating efficiency:

[0005] The traditional manual method requires the operator to aim the hot air gun at the heat shrink tubing and gradually heat it. The hot air is easy to escape, resulting in uneven heating. The operation process takes a lot of time and the sealing efficiency is low, which is especially inadequate in large-scale operations.

[0006] High security risk:

[0007] There are great safety risks when using a handheld hot air gun. The hot air concentrated in a certain position may overheat, causing the risk of burns to the operator, and may also damage the outer insulation material of the cable, further affecting the performance of the cable.

[0008] Unstable plugging quality:

[0009] The sealing effect depends largely on the experience and skills of the operator. Due to uneven hot air distribution or insufficient heating time, it is easy to cause the heat shrink tubing to be overheated or underheated locally, resulting in loose sealing or failure to achieve the ideal effect, which in turn affects the cable sealing performance and service life.

[0010] Large material loss:

[0011] In traditional operation methods, uneven heating or operating errors may cause excessive stretching or damage to the heat shrink tubing, increasing material waste and costs.

[0012] In order to solve the above problems, although some improved tools have appeared in the existing technology, most of them lack automation and intelligent design, and cannot completely solve the contradiction between efficiency, safety and quality stability. Therefore, there is an urgent need for an innovative tool that can simplify the operation process, improve operation efficiency, ensure plugging quality, and improve operation safety to meet actual needs.

Clamp the cable: manually rotate the plum nuts on the positive thread screw (15) and the negative thread screw (16) to drive the upper clamping block (12) and the lower clamping block (14) to clamp the cable (1), and confirm that the cable (1) and the heat shrink sleeve (4) are in the correct position; Step 3: Slider adjustment, including the following steps: S5. Adjust the position of the heating tube: loosen the locking pin (24), push the slider (23) to slide in the fixed slide groove (25), and adjust the heating tube (18) to be just above the heat shrink area of ​​the cable (1), ensuring that the heating tube (18) can evenly cover the heat shrink sleeve (4); S6. Adjust the position of the roller: similarly loosen the locking pin (24) of the other set of slide grooves, adjust the roller (22) to make it fit the surface of the cable (1), check the elasticity of the spring (29), and ensure that the roller (22) can adjust its position adaptively when subjected to force; S7, fix the slide block: adjust the locking pin (24) to ensure that the slide block (23) is firmly fixed; Step 4, starting the device to perform heat shrink sealing, including the following steps: S8, starting device: press the switch (2) to start the motor (5), the motor (5) drives the driving gear (10) through the transmission shaft (9), the driving gear (10) meshes with the gear plate (27), and starts to drive the cable sleeve disc column (11) to rotate; S9, heat shrinking process: the heating tube (18) starts to heat the heat shrink sleeve (4), so that the heat shrink sleeve (4) gradually shrinks and wraps around the cable (1), and the roller (22) rolls and presses on the rotating cable (1) to ensure that the heat shrink sleeve (4) is in close contact with the surface of the cable (1) to form a uniform and flat sealing layer; S10, adaptive rolling: during the rolling process, the spring (29) provides pressure adjustment, and the roller (22) always keeps in close contact with the cable (1), avoiding uneven heat shrinkage or gaps; Step 5, closing completion and shutdown, including the following steps: S11. Check the heat shrink effect: when the heat shrink sleeve (4) completely fits the cable (1) and the surface is smooth and wrinkle-free, turn off the switch (2) and the motor (5) stops running; S12, loosening the clamping mechanism: manually rotating the positive thread screw (15) and the negative thread screw (16) to separate the upper clamping block (12) and the lower clamping block (14), thereby loosening the cable (1); S13. Remove the cable: Take out the sealed cable (1) from the device and check the quality of the heat shrink seal to ensure that it is completely fitted and there is no leakage.
