Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses a portable insulator changer is shown in figure 1, including power device and the final controlling element of phase separation.
As shown in figure 2, the actuating device is characterized in that a fixture 1 is connected to the top of a piston rod 2 of a single-rod hydraulic cylinder 5 to serve as a motion output end, and the fixture 1 is detachable, is in an O-shaped appearance and is used for connecting a wire tightener on a circuit. The fixture 1 moves with the movement of the piston rod 2. The cylinder bottom 7 of the single-rod hydraulic cylinder 5 is connected to a fixed support 8 through two connecting devices to serve as a clamping device. The fixed support 8 is detachable and is used for being connected with a support post of the power transmission line. Two ends of the cylinder body of the single-rod hydraulic cylinder 5 are provided with oil ports 4 for being connected with a reversing valve 9, and along with the injection of oil, the piston starts to move and drives the piston rod 2 to move together. The piston rod 2 can output tension to the power transmission line through the clamp 1, so that the line is loosened, and then the insulator is replaced. Meanwhile, the pressure sensor 6 is arranged on the cylinder body to observe the pressure in the single-rod hydraulic cylinder 5 in real time, so that the oil quantity can be conveniently controlled.
As shown in FIG. 3, the power device is characterized in that a motor 13 drives a hydraulic pump 11 to pump out hydraulic oil in an oil tank 12, the hydraulic oil is distributed by a reversing valve 9 and is conveyed to the left side and the right side of a single-rod hydraulic cylinder 5 through oil pipes, and a piston rod 2 is enabled to move correspondingly through the hydraulic oil.
Further, a guide sleeve 3 is arranged at the position of a piston rod 2 of the single-rod hydraulic cylinder 5.
Furthermore, an overflow valve 10 is arranged on an oil pipe between the hydraulic pump 11 and the reversing valve 9.
Furthermore, the connection between each part of the actuating device is a threaded connection.
The utility model discloses the theory of operation:
when insulator replacement is carried out, the fixed support 8 is fixed on the line pillar firstly and then clamped tightly, so that the device can be hung on the pillar stably. And then, a switch on the pump station is opened, the motor 13 drives the hydraulic pump 11 to move, and the pressure oil passes through the overflow valve 10 and the reversing valve 9 to output pressure oil meeting the requirements of direction, pressure and flow, is conveyed to the oil port 4 through an oil pipe, and enters the cylinder body of the single-rod hydraulic cylinder 5. The reversing valve 9 is controlled firstly to enable the right oil port to feed oil and the left oil port to discharge oil. The hydraulic oil will thus push the inner piston to the left and the piston rod 2 will then extend. After the insulator is fully extended, a wire tightener is placed on the wire on one side of the insulator and connected with the fixture 1. And then the reversing valve 9 is controlled to enable the left oil port to feed oil and the right oil port to discharge oil. The hydraulic oil will thus push the inner piston to the right and the piston rod 2 will be retracted accordingly. During the retraction process, the clamp 1 can tighten the line connected with the clamp to enable the line to be tensioned, and the line connected with the two ends of the insulator can be loosened, so that the insulator can be replaced. And after the replacement is finished, the reversing valve 9 is controlled again to enable the right oil port to feed oil and the left oil port to discharge oil. The hydraulic oil pushes the piston inside to move leftwards, the piston rod 2 stretches out along with the piston, the circuit is loosened again, the new insulator is tightened again towards the loosened circuit on the two sides, and the replacement is finished. It is worth mentioning that in the process of inputting and outputting hydraulic oil, the pressure in the single-rod hydraulic cylinder 5 can be observed in real time through the pressure sensor 6, so that the oil quantity can be conveniently controlled. Meanwhile, safety accidents are effectively prevented, and the safety factor is improved.
