Description

Technical Field

[0001] This invention belongs to the technical field of auxiliary equipment for dismantling T-type cable heads, and relates to a T-type cable head dismantling device. Background Technology

[0002] In the field of power equipment maintenance, T-type cable heads, as key components connecting high-voltage electrical equipment, have long faced challenges in dismantling operations, including high operational difficulty, low efficiency, and susceptibility to cable head damage. Traditional dismantling methods often rely on manual pulling or prying with simple tools, which may have the following problems: 1. Low operational safety: Manual dismantling requires direct contact with live equipment, posing safety hazards such as electric shock and mechanical injury; Low dismantling efficiency: Manual operation is limited by manpower, making it difficult to apply stable and continuous pulling force, resulting in long dismantling times and unstable success rates; 2. Cable heads are easily damaged: Hard tools directly contact the surface of the cable head, easily causing insulation wear and deformation of metal parts, affecting the secondary use performance of the equipment; 3. Significant space constraints: The compact wiring environment inside the cabinet makes it difficult for traditional tools to apply force accurately, and the limited operating space further exacerbates the difficulty of dismantling. Furthermore, due to the confined space inside the ring main unit, the easy aging of cables due to heat, and the drying of lubricant, it is difficult to pull out T-type cable heads that have been in operation for many years, and excessive external force may also lead to the risk of damage to the bushing.

[0003] To address this issue, a T-type cable head disassembly device was designed to overcome the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a T-type cable head disassembly device that is simple in structure, reasonable, practical and convenient.

[0005] The present invention is achieved through the following technical solution: a T-type cable head disassembly device, comprising a cabinet, a T-type cable head and a disassembly device, wherein the T-type cable head is installed in the cabinet, a fixing frame is installed on one side of the cabinet facing the T-type cable head, and the disassembly device is installed on the fixing frame. After the disassembly device is connected to the T-type cable head, the T-type cable head is disassembled.

[0006] Preferably, the disassembly device consists of a strap, a buckle, and a drive mechanism. One end of the strap is respectively fitted onto the opposite sides of the T-shaped cable head, tightly attached to and secured to the T-shaped cable head. After securing, a buckle is installed on the other end of the strap. The buckle is connected to the drive mechanism, and the T-shaped cable head is disassembled by dragging the strap through the drive mechanism.

[0007] Preferably, the drive mechanism consists of a motor with a power supply, at least one set of bearing seats, and at least one roller. Each set of bearing seats consists of two bearing seats, which are installed on the upper and lower sides of the fixed frame, respectively. A rotating shaft is installed between the two bearing seats, and a roller is installed on the rotating shaft. A cable is wound on the roller, one end of which is fixedly connected to the roller, and the other end is tied to a buckle. The rotating shaft of the roller is connected to the motor shaft, and the rotating shaft is driven by the motor shaft to control the movement of the cable, thereby controlling the buckle and the strap to move and disassemble the T-shaped cable head.

[0008] Preferably, the bearing housings are arranged in three groups, equidistant from each other. A rotating shaft is installed between each group of bearing housings, and a roller is installed on the rotating shaft. A matching through hole is opened on the fixed frame directly below each bearing housing. The rotating shaft of the roller on one of the bearing housings in the middle or on both sides is connected to the motor shaft, and the other two rollers are driven rollers. The cable is wound around one of the rollers, or sequentially around two rollers, or around three rollers respectively, and then passes through the corresponding through hole and is connected to the buckle to adjust the torque. This adjusts the tension on the T-shaped cable head at the same motor speed, making it convenient to disassemble the T-shaped cable head.

[0009] Preferably, the middle part of the fixing frame is a cuboid structure, with extended sides on both sides of the fixing frame, and a triangular reinforcing plate between the cuboid structure and the extended sides to improve the overall strength. The upper surface of the cuboid structure is provided with bearing seats and corresponding through holes for the rollers, and elongated holes are provided on the sides of the cuboid structure to serve as observation windows for easy observation of the disassembly of the T-shaped cable head.

[0010] Preferably, the two extended sides of the fixed frame are positioned with the cabinet by magnetic blocks, and bolt holes are opened on the extended sides and the magnetic blocks respectively. After positioning, bolts are inserted into the bolt holes for fixing.

[0011] Preferably, the motor has a motor housing on its outer side, which is fixedly connected to the fixed frame by bolts. A shaft hole is provided on the side of the motor housing near the fixed frame, and the motor shaft passes through the shaft hole and is connected to the roller shaft on the bearing seat.

[0012] Preferably, the motor is equipped with a controller, which is used to control the motor to start and adjust the speed. The controller can be remotely connected to a remote controller to achieve remote control.

[0013] Preferably, the strap and the adjacent surface of the T-shaped cable head are provided with elastic material to ensure that the T-shaped cable head will not be damaged during disassembly.

[0014] Preferably, the elastic material is rubber or sponge.

[0015] The beneficial effects of this invention are as follows: 1) Safe and efficient operation: Through the coordinated action of the motor and the roller cable mechanism, the mechanical and stable force application is achieved, replacing manual operation and greatly reducing the risk of operation; with the remote control function, the operator can control the disassembly process from a safe distance, improving the overall safety of operation.

[0016] 2) Precise torque adjustment: It adopts a configurable structure with three sets of bearing seats and rollers. By selecting the cable winding path (single roller / double roller / triple roller mode), it can accurately adjust the tension of the T-type cable head at the same motor speed, adapt to the disassembly requirements of different specifications of cable heads, and avoid disassembly failure due to insufficient tension or equipment damage caused by excessive tension.

[0017] 3) Non-destructive disassembly guarantee: The inner side of the strap is equipped with a rubber / sponge elastic material layer, which forms a buffer protection when it is close to the surface of the cable head, effectively dispersing pressure and preventing wear of the insulation layer; together with the adjustable tightening force control, it ensures that there is no permanent damage to the cable head during the disassembly process.

[0018] 4) Structural reinforcement and visualization: The fixed frame adopts a rectangular body + triangular reinforcing plate design, combined with a long strip observation window, which not only ensures the overall structural strength, but also facilitates real-time observation of the disassembly progress; the installation method of magnetic block positioning + bolt fixing ensures that the device and the cabinet are firmly and reliably connected, adapting to the needs of different installation environments.

[0019] 5) Improved ease of operation: The modular design allows for quick installation and disassembly of components. Combined with the human-machine interface of the motor controller, it enables one-button start, speed adjustment and other operations, reducing the operating threshold and improving on-site work efficiency.

[0024] The disassembly device consists of a strap 4, a buckle 5, and a drive mechanism. One end of the strap 4 is respectively sleeved on the opposite sides of the T-shaped cable head 2, tightly attached to and tied to the T-shaped cable head 2.

The rotating shaft of the roller 8 is connected to the motor shaft, and the rotation is driven by the motor shaft, thereby controlling the cable 17 to drive the buckle 5 and the strap 4 to move, so as to disassemble the T-shaped cable head 2.

[0026] The bearing seats 7 are arranged in three groups, equidistant from each other. A rotating shaft is installed between each group of bearing seats 7, and a roller 8 is installed on the rotating shaft. A matching through hole 9 is opened on the fixed frame 3 directly below each bearing seat 7. The rotating shaft of the roller 8 on one of the middle or two side bearing seats 7 is connected to the motor shaft, and the other two rollers 8 serve as driven wheels. The cable 17 is adjusted by winding around one of the rollers 8, or passing around two rollers 8 in sequence, or passing around three rollers 8 respectively, and then passing through the corresponding through hole 9 and connecting to the buckle 5. This adjusts the tension on the T-shaped cable head 2 at the same motor speed 6, making it convenient to disassemble the T-shaped cable head 2.

[0027] This invention achieves mechanized and stable force application through the synergistic action of the motor and the roller cable mechanism, replacing manual operation and significantly reducing operational risks. Combined with remote control functionality, operators can control the disassembly process from a safe distance, enhancing overall operational safety. By employing a configurable structure with three sets of bearing seats and rollers, and selecting the cable winding path (single roller / double roller / triple roller mode), this invention allows for precise adjustment of the tension on the T-shaped cable head at the same motor speed, adapting to the disassembly needs of different cable head specifications and avoiding disassembly failure due to insufficient tension or equipment damage caused by excessive tension.

[0028] The middle part of the fixing frame 3 is a cuboid structure. Extended edges 10 are provided on both sides of the fixing frame 3, and a triangular reinforcing plate 11 is provided between the cuboid structure and the extended edges 10 to improve the overall strength. The upper surface of the cuboid structure is provided with through holes 9 corresponding to the bearing seat 7 and the roller 8. Long strip holes 12 are provided on the side of the cuboid structure to serve as observation windows for easy observation of the disassembly of the T-shaped cable head 2.

[0029] The two sides of the fixed frame 3 are extended 10 and positioned with the cabinet 1 by magnet blocks 13. Bolt holes 14 are opened on the extended sides 10 and magnet blocks 13 respectively. After positioning, bolts (not shown in the figure) are inserted into the bolt holes 14 for fixing.

[0031] The motor 6 has a motor housing 15 on its outer side. The motor housing 15 is fixedly connected to the fixed frame 3 by bolts. The motor housing 15 has a shaft hole 16 on the side near the fixed frame 3. The motor shaft passes through the shaft hole 16 and is connected to the shaft of the roller 8 on the bearing seat 7.

[0032] The motor 6 may be equipped with a controller (not shown in the figure). The controller is used to control the motor 6 to start and adjust its speed. The controller can be remotely connected to a remote controller (not shown in the figure) to achieve remote control. The controller and remote controller in this invention are conventional technologies and will not be explained in detail.

[0033] The adhesive strap 4 and the adjacent surface of the T-shaped cable head 2 are provided with an elastic material to ensure that the T-shaped cable head 2 will not be damaged during disassembly. The elastic material is rubber or sponge.

[0034] This invention adds a layer of rubber / sponge elastic material to the inside of the strap, forming a buffer protection when it is tightly attached to the surface of the cable head, effectively dispersing pressure and preventing wear on the insulation layer; combined with adjustable tightening force control, it ensures that there is no permanent damage to the cable head during the disassembly process.
