Description

Universal lifting device for power transmission conductor and ground wire

Technical Field

The utility model relates to a defeated electricity conductance, ground wire overhaul tool especially relate to a general hoisting device of defeated electricity conductance, ground wire.

Background

With the continuous increase of power transmission lines, the insulators on the power transmission lines are affected by natural environment, lightning stroke and external force damage all the year round, so that the zero value and the damage of the insulators on the power transmission lines are increased, and the workload of replacing the insulators is increased more and more. Because the power transmission conductor and the ground wire pass through the insulator, the power transmission conductor and the ground wire need to be lifted above the insulator in the process of replacing the insulator, at present, the power transmission conductor and the ground wire are generally lifted by the hand hoist, and the hand hoist is large in size, heavy in mass, inconvenient to carry, high in operation labor intensity, time-consuming and labor-consuming in operation, long in maintenance time and low in working efficiency.

Disclosure of Invention

The utility model relates to a solve above-mentioned technical problem, provide a general hoisting device of conductance, ground wire, its structure is small and exquisite, the quality is light, portable can reduce operation intensity of labour, and operation labour saving and time saving shortens repair time, improves work efficiency.

The technical solution of the utility model is that:

general hoisting device of conductance, ground wire, including the mount pad, its special character lies in: the rear part of the mounting seat is provided with a socket with a downward opening, the front part of the mounting seat is provided with a lead screw which penetrates through the mounting seat up and down through threads, the upper end of the lead screw is fixedly provided with a handle, and the lower end of the lead screw is rotatably provided with a lifting hook.

Further preferably, a locking bolt vertically penetrating into the socket is installed at the rear part of the installation seat through threads, so that the installation stability of the installation seat is improved.

Further preferably, a check ring is arranged at the lower end of the screw rod, a threaded cover is sleeved on the screw rod above the check ring, a threaded seat is installed at the lower end of the threaded cover through threads, and the lifting hook is installed on the threaded seat.

Further preferably, the lifting hook is hinged with the threaded seat, so that the guide wire and the ground wire can be conveniently hooked.

The utility model has the advantages that:

this general hoisting device of conductance, ground wire structure is small and exquisite, the quality is light, portable, changes insulator operation, and it can easily go up and down to lead, the ground wire, has reduced operation intensity of labour, and operation labour saving and time saving has shortened maintenance time, has improved work efficiency.

Detailed Description

As shown in fig. 1 and 2, the universal lifting device for the power transmission conductor and the ground wire comprises a mounting base 1, a socket 2 with a downward opening is arranged at the rear part of the mounting base 1, a locking bolt 3 vertically penetrating the socket 2 is mounted at the rear part of the mounting base 1 through threads, a lead screw 4 vertically penetrating the mounting base 1 is mounted at the front part of the mounting base 1 through threads, a handle 5 is fixedly mounted at the upper end of the lead screw 4, a retainer ring 6 is arranged at the lower end of the lead screw 4, a threaded cover 7 is sleeved above the retainer ring 6 on the lead screw 4, a threaded base 8 is mounted at the lower end of the threaded cover 7 through threads, and a lifting hook 9 is hinged to the threaded base 8.

During operation, firstly, the socket 2 of the mounting seat 1 is inserted on an overhead iron support above the insulator, the mounting seat 1 is fixed by the locking bolt 3, then the lifting hook 9 is hooked on the guide wire and the ground wire, the lifting hook 9 is lifted by rotating the screw rod 4 through the handle 5, the guide wire and the ground wire which are hooked on the lifting hook 9 are lifted above the insulator, the insulator is replaced, after the insulator is replaced, the screw rod 4 is reversely rotated through the handle 5, the lifting hook 9 falls, the guide wire and the ground wire fall to the initial position, and the mounting seat 1 is detached.

The above description is only an example of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
