Description

Technical Field

[0001] This utility model relates to the field of cable repair technology, and in particular to a cable outer sheath repair device. Background Technology

[0002] With the rapid development and continuous improvement of public transportation facilities such as high-speed railways and subways, their construction techniques and quality are constantly improving. However, the sheer volume of cables laid during rail transit power construction often results in numerous instances of damage requiring repair. Currently, common repair methods include using a gas-filled spray gun to heat and wrap fire-retardant tape, or using a gas-filled spray gun to heat and wrap zipper-type heat shrink tubing. However, both of these methods have certain drawbacks.

[0003] 1. Due to cost and site conditions, the existing repair methods mainly involve using gas cylinder spray guns for heating. However, the use of gas cylinder spray guns results in open flames, which poses a low safety risk in some enclosed areas.

[0004] 2. During the heating process of the gas canister spray gun, it is difficult to control the flame size and achieve uniform heating. The flame temperature is uneven, the repair quality is unstable, and it may even cause the repair material to be overheated and damaged.

[0005] 3. The above-mentioned disadvantages also exist when using zipper-type heat shrink tubing to repair cables, and the heat shrink tubing is often a different color from the cable, which reduces the aesthetics.

[0006] 4. In actual operation, heat shrink tubing is prone to cracking, which does not achieve a good repair effect and easily leads to rework.

[0007] Currently, some cable insulation heating tools exist, but most are quite complex, and their direct application would incur significant manpower and equipment costs due to the diverse and complex environments at the damage sites. Therefore, there is an urgent need to find a safe and reliable cable sheath repair device to address the problems in existing technologies. Utility Model Content

[0038] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0039] refer to Figure 1-3A cable repair device includes an outer sheath layer 1, a heating band 2, and an inflatable sleeve 3. In this embodiment, the cable 6 includes a cable core 6.2 and a cable outer sheath 6.1. The outer sheath layer 1 is attached to the damaged portion of the cable outer sheath 6.1 on the cable 6. The heating band 2 is wrapped around the outer sheath layer 1, and the inflatable sleeve 3 is wrapped around the heating band 2. The heating band 2 is used to heat the outer sheath layer 1. The inflatable sleeve 3 is used to fix the heating band 2 and the outer sheath layer 1 to the cable 6.

[0040] This embodiment of a cable repair device involves applying a suitable outer sheath layer of the same material as the cable outer sheath according to the shape and size of the damage to the cable's outer sheath, then heating it with a heating band and fixing it in place with an inflatable sleeve, thus achieving a safe, reliable, and convenient repair operation for the cable.

[0041] In this embodiment, a glass fiber heating tape is used. Specifically, the glass fiber tape is formed by heating a resistance wire. The glass fiber tape has a flat shape, with the resistance wire placed in the middle for concentrated heating. The surface of the fiber tape is covered with a Teflon heat-resistant non-stick material to prevent the molten outer sheath from sticking to it, thus improving the process effect. The heating temperature can reach 250℃. Taking advantage of the low melting and softening temperatures of the plastic outer sheath, the damaged area is trimmed and filled using the existing outer sheath material of the same type of cable. After heating, melting, cooling, and shaping, it forms a whole, improving the construction process and efficiency, saving construction costs, and achieving the repair effect.

[0042] Furthermore, the inflatable cuff consists of an inflatable inner liner and an outer layer, both of which should be made of high-temperature resistant materials. The inner liner can be made of fiberglass reinforced with a thin metal sheet, and the outer layer can be made of fiberglass.

[0043] In this embodiment, an inflatable cuff, commonly found in inflatable blood pressure monitors, is used to cover the heating band after heating. Inflation is then applied to apply internal pressure, restoring the softened cable sheath to its original shape.

[0044] It also includes a power supply 4 and an air pump box 5; both the heating band 2 and the air pump box 5 are electrically connected to the power supply 4, which supplies power to the heating band 2 and the air pump box 5; the inflatable cuff 3 is connected to the air pump box 5, which inflates the inflatable cuff 3. The power supply 4 is a portable power source. The air pump box 5 includes an air pump, a control switch, a pressure sensor, and a pressure relief switch; the air pump inflates the inflatable cuff 3; the control switch is connected to the air pump and controls its operation; the pressure sensor detects the air pressure of the inflatable cuff 3; and the pressure relief switch is connected to the inflatable cuff 3 and releases pressure from it.

[0045] This embodiment uses a small portable power supply that can output 220V AC and 24V DC to power the entire device; the integrated air pump and portable power supply make it easy to carry and improve repair efficiency.

[0046] A heating strip reel 7 for fixing and controlling the heating strip 2 is also provided between the heating strip 2 and the power supply 4; the heating strip 2 is wound around the heating strip reel 7; the heating strip reel 7 is also provided with a switch for controlling the on / off state and setting of the heating strip 2.

[0047] The inflatable cuff 3 is also provided with a buckle 3.1 for fixing the inflatable cuff 3.

[0048] The method of using the cable repair device in this embodiment is as follows:

[0049] (1) First, clean and repair the damaged points of the cable outer sheath; then, clean and repair the outer sheath layer of the same cable outer sheath material and cover it with the damaged points of the cable outer sheath.

[0050] (2) Wrap the heating tape around the outer sheath, making sure the center heating part of the heating tape is aligned with the notch, and ensure that the wrapping is tight;

[0051] (3) Wrap the inflatable cuff around the heating belt and lock the buckle.

[0052] (4) Start the heating plate to heat the heating belt, and stop heating after heating to the appropriate time and temperature;

[0053] (5) Keep the inflatable cuff pressurized for a period of time;

[0054] (6) After the heating band gradually cools down, open the pressure relief valve to release the pressure, and then gradually remove the repair device and check the repair results.

[0055] The cable cross-section after repair is as follows Figure 3 As shown, from the inside out are cable 6, cable outer sheath 6.1, heating band 2, and inflatable sleeve 3.
