Description

Technical Field

[0001] The utility model belongs to the technical field of heat shrinkage auxiliary equipment, and in particular relates to a cable heat shrinkage tube heating auxiliary device. Background Art

[0002] The production of cable joints is the most important link in cable construction. Due to their relatively hidden locations, they are also the weakest link in cable operation and maintenance. The safety of cable operation depends largely on the production and management of cable joints. According to statistics on accidents in cable operation in recent years, cable joint accidents account for more than 60%. The main reason is that the production process of the high-voltage junction box of the cable intermediate joint is not up to standard and is far from its designed service life. In addition, due to the particularity of its location, fault detection and treatment are relatively difficult, resulting in power outages and serious economic losses. This reminds us that we should pay attention to the design, construction and technical management of cable joints.

[0003] In recent years, heat shrink tubing has been vigorously promoted and applied in cable joints. It has excellent flame retardant and insulation properties, is very soft and elastic, has a low shrinking temperature and shrinks quickly. It can be widely used in wire connection, wire end processing, solder joint protection, harness identification, insulation protection of resistors and capacitors, corrosion protection of metal rods or pipes, antenna protection, etc. This process has good sealing performance, high insulation strength, simple, standardized and hygienic production, no damage to the original core wire insulation, power supply can be restored after production, and has the advantages of small cable head size, light weight, beautiful appearance, no need for local grounding of cable head, and easy management. This technology is green and environmentally friendly and has good promotion value.

[0004] Generally, a blowtorch or a spray gun is used to heat the terminal with the heat shrink tube so that the heat shrink tube fixes the terminal to the cable. However, this heating method requires manual hand-held blowtorch or spray gun, which poses a safety hazard and easily causes uneven heating of the heat shrink tube. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a cable heat shrink tube heating auxiliary device to solve the safety hazards existing in the prior art when heating the cable heat shrink tube and the technical problems of uneven heating of the heat shrink tube.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the auxiliary device for heating a cable heat shrink tube of the utility model is:

[0007] A cable heat shrink tube heating auxiliary device, comprising:

[0008] Workbench: The length direction of the workbench is defined as the left-right direction, and the width direction of the workbench is defined as the front-back direction; a limit slot with a top opening is provided in the middle of the workbench, and a set of cable brackets and cable clamps are provided on the left and right sides of the limit slot on the workbench, and the cable clamps are fixed on the cable brackets to fix the cables;

[0009] Driving assembly: arranged in the limiting groove, including a driver and a slide seat, the driving end of the driver is fixedly connected to the slide seat, and is used to drive the slide seat to move in the left and right directions;

[0010] Adjustment assembly: arranged on the slide seat, including a motor, a screw and a slider, the output shaft of the motor is connected to the screw in a transmission manner, two sliders are provided, the surface of the screw is provided with two sections of external thread segments with opposite rotation directions, and the two sliders are respectively threadedly connected to the two sections of external thread segments;

[0011] Heating components: Two groups are provided, which are fixed on the sliders respectively. Each group of heating components includes an electric heating sleeve and a heating bracket. The electric heating sleeve is fixed on the heating bracket and is used to wrap around the heat shrink tube and heat the heat shrink tube. When the two sliders are moved to the set position, the two electric heating sleeves can be pressed against each other.

[0012] Guide and fixation assembly: comprises a guide rod and a first fixed block and a second fixed block. The guide rod is arranged parallel to the screw rod and spaced apart from each other. The first fixed block and the second fixed block are both fixed on the slide seat. The guide rod passes through two slide blocks and cooperates with the slide block guide sliding. The two ends of the guide rod are respectively fixed on the first fixed block and the second fixed block.

[0013] Beneficial effects: The cable clamp can fix the cable with the heat shrink tube on the workbench, which is convenient for the installation and heating of the heat shrink tube. At the same time, the two sliders drive the electric heating sleeves to move in opposite directions under the rotation of the screw rod, so that the two electric heating sleeves are separated, which is convenient for the installation of the heat shrink tube. After the heat shrink tube is installed, the two sliders drive the electric heating sleeves to move toward each other under the rotation of the screw rod, so that the two electric heating sleeves are in contact, and the electric heating sleeves wrap the heat shrink tube so that the heat shrink tube is evenly heated, which is conducive to the uniform shrinkage of the heat shrink tube; and the driver slowly pushes the slide seat to start heating from one end of the heat shrink tube first, which is conducive to the shrinkage of the heat shrink tube from one end and the exhaust of the air in the heat shrink tube. The utility model of the cable heat shrink tube heating auxiliary device eliminates the safety hazards of artificial heating. At the same time, the heat shrink tube is evenly heated, and then shrinks evenly, and it is not easy to produce wrinkles and cracks.

[0014] Furthermore, the driver is an electric push rod.

[0015] Beneficial effects: simple structure and easy to use.

[0016] Furthermore, one end of the screw rod away from the motor is rotatably connected to the first fixed block.

[0017] Beneficial effect: the screw rod and the guide rod can share the first fixed block, thus reducing the use of materials.

[0018] Furthermore, the cross section of the electric heating sleeve is semicircular.

[0019] Beneficial effect: When the two electric heating sleeves are against each other, they can just wrap the heat shrink tube, so that the heat shrink tube is heated more evenly.

[0020] Furthermore, the heating bracket is L-shaped, one end of which is fixedly connected to the electric heating sleeve, and the other end of which is fixedly connected to the slider.

[0021] Beneficial effect: When the two sliders are close to each other, the opposite sides of the two electric heating jackets can be in full contact.

[0022] Furthermore, a roller is arranged at the bottom of the slide seat.

[0023] Beneficial effect: It is conducive to the movement of the slide. BRIEF DESCRIPTION OF THE DRAWINGS
