Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a portable electric hydraulic cable supporting and fixing device. Background Art

[0002] In the urban rail transit power supply system, the main power supply ring network of the power supply system mainly uses 35kV cables to supply power to stations along the line. When the line power grid construction requires the stripping of cables, due to the relatively narrow space on the line and the lack of a dedicated site for the production of intermediate heads, the cables are often temporarily placed on tables, chairs or rails for processing;

[0003] At the same time, during the formal operation period, the power cable is exposed to the natural environment without protection. It is affected by the temperature, natural light and other weather conditions for a long time. The cable outer sheath shrinks, causing the middle head armor layer, inner sheath, and copper shield to move relative to each other, and the copper braided wire and copper mesh between the cables on both sides are loose. After the loosening, a circulating current is generated, which causes local heating and gradually destroys the main insulation. If this problem develops further, it may cause the outer sheath of the power cable body to break, the middle joint to pull off, the head to explode and other serious problems. Such problems will bring great safety hazards to the later operation. As the backbone network of the power supply system, the cable stripping process of the ring network cable is affected by space and time, causing personnel to bend or squat to repair the cable head, which is time-consuming and labor-intensive and has the disadvantage of affecting the accuracy of the operation.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to solve the technical problems in the prior art that the cables are exposed to the natural environment without protection, resulting in the outer sheath of the power cable body being broken, the middle joint being pulled off, and the head being blown; and the cable stripping process is affected by space and time, causing the personnel to bend or squat to repair the cable head, which is time-consuming and labor-intensive, affecting the operation accuracy, please refer to Figure 1-3 , providing the following technical solutions:

[0023] In this embodiment, a portable electric hydraulic cable support and fixing device includes an oil tank 5, a rechargeable battery 12 and a support and fixing housing 14. A motor seat 2 is arranged inside the support and fixing housing 14. An oil pump motor 3 is installed at the bottom of the motor seat 2. The oil pump motor 3 and the rechargeable battery 12 are connected by a wire. A gear pump 4 is arranged at the output end of the oil pump motor 3. The gear pump 4 is fixedly connected to the oil tank 5. A lifting and telescopic rod 7 is arranged on the support and fixing housing 14. A fixed clamp seat 8 is fixedly connected to the upper end of the lifting and telescopic rod 7. A ball head universal joint 10 is arranged inside the fixed clamp seat 8. A cable fixing clamp 11 for clamping the cable is arranged above the ball head universal joint 10. The ball head universal joint 10 can rotate 360° around the center. The gear pump 4 is driven by the detachable rechargeable battery 12 and directly driven by the reduction motor. The gear pump 4 is a positive displacement rotary pump, which is composed of two gears, a pump body and a front and rear cover to form two closed spaces. When the gear rotates, the originally meshed gears in the cavity at the inlet end gradually separate, and the volume of the space changes from small to large, forming a vacuum to suck the liquid. As the gear rotates, the fluid flows out from the gap between the gear and the inner wall of the cavity. The oil pump motor 3 drives the gear pump 4 with hydraulic oil to drive the lifting telescopic rod 7 to rise and fall, thereby supporting the cable. The cable fixing clamp 11 with a clamp structure is used to clamp and fix the cable. It is easy to carry, simple to operate, and has strong versatility. The cable is clamped firmly and steadily. The ball head universal joint 10 enables it to have a wider clamping angle and application range, reducing the input of traditional labor, saving time and labor, and improving work efficiency.

[0024] In this embodiment, a handle 1 is provided at the upper end of the supporting and fixing shell 14 , and the handle 1 is fixedly connected to the motor base 2 , so that the handle 1 is convenient for lifting and moving the device.

[0025] An oil pipe 6 is fixedly connected to one side of the oil tank 5 , and the oil pipe 6 is connected to the lifting and telescopic rod 7 .

[0026] A locking bolt 9 for fixing the ball joint 10 is provided on one side of the fixing clamp seat 8 .

[0027] In this embodiment, the cable fixing clamp 11 includes an upper fixing seat 1101 and a lower fixing seat 1102 . One end of the upper fixing seat 1101 is rotatably connected to the lower fixing seat 1102 via a damping shaft 1103 . An arc-shaped clamping plate 1105 is disposed inside the upper fixing seat 1101 and the lower fixing seat 1102 .

[0028] The inner wall of the arc-shaped clamping plate 1105 is provided with an anti-skid groove 1106. The upper fixing seat 1101 and the lower fixing seat 1102 are fixedly connected to the arc-shaped clamping plate 1105 by means of a spring 1107. The anti-skid groove 1106 has an effective anti-skid effect on the cable. The spring 1107 enables the arc-shaped clamping plate 1105 to fix cables of different sizes, thereby avoiding the cables being too tight and extending the service life of the cables. When the cables swell due to heat, the cables will squeeze the spring 1107, thereby expanding the fixing radius of the cables to a certain extent, further avoiding the arc-shaped clamping plate 1105 from tightening the cables and extending the service life of the cables.

[0029] A clamping column 1104 is provided at the bottom of the lower fixing seat 1102 , and the clamping column 1104 is fixedly connected to the ball head universal joint 10 . The clamping column 1104 and the ball head universal joint 10 are threadedly connected, and different types of cables can be clamped by replacing the cable fixing clamp 11 .

[0030] The other end of the upper fixing seat 1101 is fixedly connected to the lower fixing seat 1102 via an eccentric cam handle 13, and the eccentric cam handle 13 is used to lock and fix the cable.

[0031] Working principle: When in use, after raising the lifting telescopic rod 7 to a suitable working height through the operating device switch, open the cable fixing clamp 11, separate the upper fixing seat 1101 and the lower fixing seat 1102 at a certain angle, and then place the cable on the arc-shaped clamp 1105. The upper fixing seat 1101 and the lower fixing seat 1102 open and close around the damping shaft 1103, rotate the eccentric cam handle 13, and quickly drive the screw rod to allow the upper and lower arc-shaped clamps 1105 of the cable fixing clamp 11 to lock the cable. The inner wall of the arc-shaped clamp 1105 is provided with an anti-slip groove 1106, so that whether it is cable fixing or making and repairing process, the cable and the cable support fixing device can be firmly fixed, and the clamped cable will not be damaged. The cable fixing clamp 11 is connected to the ball head universal joint 10, which can rotate 360° around the center in the horizontal plane and swing a certain amplitude in the vertical direction. It can adapt to cables at different angles. The ball head is fixed by a C-shaped fixing clamp seat 8 and can be stopped and locked at any angle. The staff can take a suitable work position to carry out cable production and cable terminal head repair according to the working environment. It is very convenient and quick to use.
