Description
DEVICE FOR LIVE ERECTION OF POLE LU503274
[0001] The present disclosure relates to the technical field of devices for erection of electric poles, more particularly to a device for live erection of a pole.
[0002] With the development of society in recent years, a higher requirement is put forward on power supply. In order to ensure the reliability of power supply, live working has become more and more important. When it is needed to erect a new high-tension pole or replace an old high-tension pole in a middle section of the high-tension wire, generally in the case of no interruption of power, it is needed to spread open two parallel wires first to increase the distance between the two wires, then erect the pole and finally straighten the pole. During the process of live erection of poles, insulation mainly relies on air and the upper end of the pole is sleeved with an insulating sleeve to achieve an auxiliary insulation effect.
[0003] In the prior art, during the erection of the electric pole, one end of the electric pole is located in a pothole, and the other end of the electric pole is inclined upward by the lifting action of the lifting appliance, so that the electric pole gradually transitions from a horizontal state to a vertical state. However, when applied to the technology of live erection of poles, the above-mentioned technology has major drawbacks. The lifting appliance will interfere with the wire, impacting the normal erection of the pole, and the lifting appliance will contact the wire, having potential safety hazards. If the lifting appliance lifts the electric pole as a whole to above the high-tension wire and then erects the pole from top to bottom, the height that needs to be met puts forward a high requirement on the lifting appliance and the energy consumption is high.
[0004] Therefore, it is needed to provide a device for live erection of a pole, which can assist an electric pole in completing erection under the condition that a high-tension wire is not powered off, avoid interference with the high-tension wire and reduce the potential safety hazards of operators.

[0017] 1. The moveable arm and the connecting arm are arranged in the present disclosure, two ends of the first hydraulic rod are hinged with the moveable vehicle body and the moveable arm respectively, thus the first hydraulic rod can jack the moveable arm and the connecting arm as a whole to realize the adjustment in the height direction. A fixed base is hinged to a lower end of the connecting arm, and two ends of the second hydraulic rod are hinged with the fixed base and the connecting arm respectively, so that the fixed base can rotate around the hinged joint with the connecting arm, realizing the adjustment of degree of inclination of the fixed base relative to the horizontal position, and facilitating the first arm and the second arm to cut in and hold tight the electric pole from different angles. The driving device is arranged at an upper end of the fixed base, and the driving device can drive the positioning column to rotate around its axial line; when the first arm and the second arm hold the electric pole tight, the electric pole first can be lifted by certain height in a horizontal state under the action of the moveable arm and then can rotate around the axial line of the positioning column under the driving of the driving device, so that one end of the electric pole turns upward and the other end turns downward to complete the erection of the electric pole. After the erection of the electric pole, the moveable arm and the connecting arm are LU503274 located at the middle position of the electric pole, without interfering with the high-tension wire above, thus the high-tension wire does not need to be powered off and the potential safety hazards of operators are reduced, meanwhile, compared with the top-down erection mode from above the high-tension wire, the technique in this application does not need to lift the electric pole to above the high-tension wire, reducing power consumption. Insulation pads are arranged on insides of the first arm and the second arm, further avoiding conduction of electricity to the moveable arm and reducing the potential safety hazards of operators.
[0018] 2. The moveable arm preferably adopts a hydraulic telescopic rod, to facilitate the horizontal movement of the electric pole during the erection process and ensure the lower end of the electric pole to be correctly located to a pothole.
