Problems solved by technology

[0003] At present, the manual repair method is widely used in China to repair the broken strand ground wire, that is, the staff uses the flying car or pulley to reach the damaged strand along the ground wire and adopts the corresponding repair method. Sometimes live work is required to ensure normal power supply. , this method has potential safety hazards, especially for ground wires with small diameters, and the mechanical strength of the broken strands is further reduced, which is likely to cause the ground wires to be broken during walking

Embodiment 1

[0023] see Figure 1 to Figure 3 , the present invention provides an overhead ground wire repairing device, comprising a structural frame 1, a motor 2 and a clutch 3, the motor 2 is arranged inside the structural frame 1, the output end of the motor 2 is connected to the clutch 3, The top of the motor 2 is provided with a signal receiver 4 for receiving control commands, the clutch 3 is provided with a first port 5 and a second port 6, and a traveling device is provided above the first port 5, and the traveling device Connected to the first port 5, a pressing mechanism is arranged above the second port 6, a repair mechanism is arranged above the pressing mechanism, the repair mechanism is connected to the structural frame 1, and the pressing mechanism The tightening mechanism is used to compress the repairing mechanism. The repairing mechanism is used to repair the overhead ground wire 16. The signal receiver 4 above the motor 2 receives the operator's control instructions, an...

Embodiment 2

[0028] Compared with Embodiment 1, the difference in this embodiment is that the steel mold 12 is a regular hexagon, and both the upper steel mold 12-1 and the lower steel mold 12-2 are half of the regular hexagon and symmetrical to each other. The upper repair pipe 13-1 is a large semicircular hollow pipe that fits with the overhead ground wire 16, and the lower repair pipe 13-2 corresponds to a small semicircular hollow pipe, which can make the device more firm after crimping , can also ensure the electrical conductivity of the repaired overhead ground wire 16.

Embodiment 3

[0030]Compared with Embodiment 1 and Embodiment 2, the difference in this embodiment is that the distance between the road wheel 8-1, the driving wheel 8-2 and the driven wheel 8-3 is the same as the diameter of the overhead ground wire 16, It can ensure that the device is close to the overhead ground wire 16 and runs smoothly. The motor 2 is a horizontal motor with feet, which makes the installation of the motor 2 more convenient.

Abstract

The invention discloses an overhead ground wire repair device, which comprises a structural frame, an electric motor and a clutch which are connected. The electric motor is arranged inside the structural frame. An output end of the electric motor is connected with the clutch. A signal receiver for receiving a control command is arranged at the top of the electric motor. The clutch is provided witha first port and a second port. A traveling device is arranged above the first port. The traveling device is connected with the first port. A pressing mechanism is arranged above the second port. A repair device is arranged above the pressing mechanism. The repair device is connected with the structural frame. The pressing mechanism is used for pressing the repair device. The repair device is used for repairing an overhead ground wire. Instead of the staff, the overhead ground wire repair device can repair the overhead ground wire which is broken by using a repairing pipe, the efficiency of the repair work of the overhead ground wire can be increased, the stability of the power supply of a transmission line is ensured, the occurrence of disconnection accidents is avoided, and the repair effect is good.

Description

technical field [0001] The invention relates to a repair device, in particular to an overhead ground wire repair device. Background technique [0002] In addition to bearing the thermal effect of short-circuit current, load current, and lightning current, the overhead ground wire will also be attacked and damaged by the external harsh environment during operation, resulting in damage to the ground wire and even broken strands. Broken strands will not only cause uneven stress distribution of the ground wire, excessive local stress, and increase the possibility of further disconnection, but also reduce the lightning protection effect of the ground wire, increase the risk of lightning strikes on the line, and eventually lead to the outage of the line. Especially for ultra-high voltage and ultra-high voltage lines, the ground wire also shoulders the mission of serving as a carrier communication channel and supplying power to low-power users. Therefore, it is extremely important ...
