The electric potential monitoring device is in rolling connection with the power transmission conductor, is low in failure rate, safe and reliable in operation, can provide safety guarantee for safety of potential operators, can move along the power transmission conductor, increases the operation range, does not need to be repeatedly installed and fixed, and is time-saving and labor-saving in operation and high in maintenance efficiency.
Description
Technical Field
The utility model relates to a balladeur train for the transmission line operation especially relates to a special auto-lock balladeur train of live working lift.
Background
The power transmission line enters an electric field live working, which is an essential link in electric power overhaul. At present, the way of entering the electric field by the transmission line is: utilize unmanned aerial vehicle to walk around and the ground that falls to on one's body the safety rope of rope and the equipotential operation personnel of lift from transmission conductor top, then fix the rope and the safety rope end that falls to the ground on ground through the earth anchor, the equipotential operation personnel take the lift to rise and get into the electric field and overhaul the operation. The rope of the elevator and the safety rope on the equipotential operator are damaged due to friction with the power transmission conductor, the potential operator forms a falling threat, the operation mode can only carry out fixed-point operation on the power transmission line, when multi-point operation is carried out, the rope of the elevator and the safety rope on the equipotential operator need to be repeatedly installed and fixed, the operation is time-consuming and labor-consuming, and the overhauling efficiency is low.
Disclosure of Invention
The utility model relates to a solve above-mentioned technical problem, provide a special auto-lock balladeur train of live working lift, its and transmission conductor roll connection, the fault rate is low, operation safe and reliable, the peer potential operation personnel safety provides the safety guarantee, and it can follow the transmission conductor and remove, and increase operation scope need not the reinstallation fixed, operation labour saving and time saving, and maintenance efficiency is high.
The technical solution of the utility model is that:
the special self-locking sliding frame for the live working lifter comprises a square frame body, and is characterized in that: the side opening is formed in a vertical surface of the frame body, the main pulley is installed above the side opening in the frame body, the inverted U-shaped closing frame is covered on the frame body, and the vertical surface of the closing frame and the vertical surface of the corresponding side of the frame body are installed in a vertically sliding mode.
Further preferably, a vertical surface of the closed frame is provided with a long hole extending in the vertical direction, the main pulley is mounted on the frame body through a bolt, and the bolt penetrates through the long hole.
Further preferably, a suspension loop is installed at the lower part of the frame body for fixing the rope of the elevator.
Further preferably, a sub-pulley is installed at a lower portion of the frame body for passing the protection rope.
Preferably, a pull ring is arranged at the upper end of the closing frame, so that the closing frame can be conveniently lifted.
Further preferably, the lacing wire is welded between the bottom surface and the vertical surface of the frame body, so that the structural strength of the frame body is improved.
The utility model has the advantages that:
1. because the main pulley in the frame body is in rolling connection with the power transmission conducting wire, the fault rate is low, the operation is safe and reliable, safety guarantee is provided for safety of potential operation personnel, the potential operation personnel can move along the power transmission conducting wire, the operation range is enlarged, repeated installation and fixation are not needed, the operation is time-saving and labor-saving, and the overhauling efficiency is high.
2. Because the cover is buckled the type of falling U closure frame on the support body and the support body slidable mounting from top to bottom, the closure frame slides down under the action of gravity and seals the side opening of support body, prevents that the support body from droing, has improved the operation security, provides the safety guarantee to the peer potential operation personnel safety.
