Detailed Description
The following detailed description will be made with reference to the accompanying drawings and examples, so as to solve the technical problems by applying technical means to the present invention, and to fully understand and implement the technical effects of the present invention. It should be noted that, as long as no conflict is formed, the embodiments and the features in the embodiments of the present invention may be combined with each other, and the technical solutions formed are all within the scope of the present invention.
Referring to fig. 3, the insulator 9 has three places where wires can be erected, generally, only one wire is erected on one insulator, when the insulator 9 breaks down and needs to be replaced, the device of the present embodiment is adopted to pull the live wire 10 on the insulator 9 away, so that the live wire 10 is separated from the original position of the insulator 9, and the live wire 10 is erected again after the insulator is replaced.
Referring to fig. 1, live conductor 10 is located on one side of insulator 9 and is pulled out of position using the present device.
The specific process is as follows:
The base 1 is fixed on the working vehicle by bolts, and in an initial state, an electric telescopic rod 7-3 in the electrified lead catching part 7 is in a contraction state, and an upper port of the scissors structure is in an opening state.
The two independent servo motors are respectively a Z-axis servo motor and an X-axis servo motor, wherein the Z-axis servo motor is arranged in the Z-axis sliding table 4 and in a plate spanned between the two vertical slideways 3-1, the Z-axis servo motor is not shown in the schematic diagram in figure 1, the thickness of the plate provided with the Z-axis servo motor is not thick enough, the driving technology of the part is the prior art, and therefore a corresponding technical scheme is not given in detail in the embodiment. The X-axis servo motor is arranged in the X-axis sliding table 6 in the same way.
Firstly, a Z-axis servo motor drives a Z-axis sliding table 4 to slide upwards along a vertical slideway 3-1, so that an X-axis moving platform 5 and a live conductor capturing part 7 are carried to move upwards synchronously, the operation is used for adjusting the height position of the live conductor capturing part 7 to enable the live conductor capturing part 7 to be located near an insulator 9 to be replaced and approximately level with the height of a live conductor 10, the height position is slightly lower, and the Z-axis servo motor stops after the estimated height position is reached. Then, the X-axis servo motor drives the X-axis sliding table 6 to slide towards the direction of the charged conducting wire 10 until the sliding is stopped below the charged conducting wire, at the moment, the upper port of the charged conducting wire capturing part 7 is opposite to the charged conducting wire 10, at the moment, the Z-axis servo motor is started to drive the Z-axis sliding table 4 to slide upwards, the charged conducting wire 10 is collected into the charged conducting wire capturing part 7, the electric telescopic rod 7-3 is extended, the open state of the upper port of the charged conducting wire capturing part 7 is changed into the closed state, and the charged conducting wire 10 is locked inside the charged conducting wire capturing part 7.
