Problems solved by technology
This method is based on manually performing live work on the T-clamp of the high-voltage line in the equipotential state. During the work, it will be limited by the distance of the live work, making it difficult for the operator to perform the action, thus causing the bolt tightening torque to fail to meet the national standard, or even There is a situation where the wrench socket cannot cover the bolt
In addition, artificial equipotential live work must be approved by the dispatching department, and the approval process is cumbersome, making it difficult to replace loose or corroded bolts in time, increasing the risk of accidents

The invention discloses a device for dismounting a T-shaped wire clamp of a high-voltage wire in hot-line work. The device comprises a lifting platform, a four-axis platform and an end execution mechanism, wherein the four-axis platform and the end executing mechanism are both of a conductive structure; the four-axis platform is fixedly mounted at the top of the lifting platform, and an insulatinglayer is arranged between the four-axis platform and the lifting platform; the four-axis platform can move in the X direction, the Y direction and the Z direction and rotate in the Z direction. The four-axis platform is provided with an equipotential mechanism capable of establishing an equipotential relationship with a high-voltage bus; the end executing mechanism is detachably buckled on the four-axis platform; and a nut breaking and cutting device capable of moving in the X direction, the Y direction and the Z direction is arranged on the end executing mechanism. A manual live working modeis replaced by the device, so an operator can be kept away from a high-altitude and dangerous working environment, and the accidents such as electric shock and high-altitude falling are avoided; theT-shaped wire clamp of the high-voltage line can be disassembled through the end executing mechanism under the live-line condition, the negative influence caused by power failure is avoided, and the power supply reliability is improved.
Description
technical field [0001] The invention belongs to the field of electric power maintenance engineering equipment, and in particular relates to a device for dismantling a T-shaped clamp of a high-voltage line for live work. Background technique [0002] The high-voltage lines of the substation are densely distributed with T-shaped clamps of high-voltage lines, and their function is to divert the high-voltage lines to various cities and towns. However, since the T-shaped clamp of the high-voltage line is exposed outdoors all the year round, it is easily affected by the weather and the environment. For example, snowfall and wind will cause the high-voltage line to vibrate, causing the bolts on the connecting plate to loosen and generate electric sparks, causing a disconnection accident; at the same time The bolts on the connection plate will also be severely corroded in harsh environments, and will form bonds with the connection plate, which will easily cause accidents. Therefore...
