Technical Field

The invention relates to the technical field of power transformation maintenance tools, in particular to a support used on an insulating rod high-voltage test site.

Background

The insulating tool is a unified name of an insulating tool composition specially used in an electric power system, can be used for live working, live overhaul and live maintenance working tools, and a common insulating tool comprises an insulating operating rod and a tool made of an insulating pipe or a rod with an end part accessory. Generally comprises an operating rod, a wire binding rod, a hook head rod and a universal operating rod.

The insulating rod is an indispensable safety construction appliance for electric work, plays an important role in insulation between a human body and high voltage, and is related to safety of people, a power grid and equipment.

The high-voltage test has the largest workload on a working site, the most difficult operation is the lifting rod operation, and the most dangerous is the lifting rod operation. Because in the test process, a large amount of time is needed for lifting the rod, and the arm becomes acid and shakes after the rod lifting time is long, the rod body is easy to drop and the accident that other electrified parts are touched by mistake is easily caused.

Therefore, it is desirable to provide a field bracket for high-voltage testing of an insulating rod, which solves the above problems.

As a further improvement of the invention, the lower end of the swing arm is rotatably connected to the side part of the fixed mounting plate through a rotating shaft, and a limit baffle for blocking the lower end of the insulating rod is fixed on the swing arm.

As a further improvement of the invention, a limit fixed block used for blocking the lower end of the insulating rod is fixed on the swing arm, a trapezoidal groove corresponding to the lower end of the insulating rod is formed in the limit fixed block, and the width of a notch of the trapezoidal groove is larger than that of the bottom of the groove.

As a further improvement of the invention, the upper end of the pointed end is fixedly connected with a supporting seat, and the lower end of the fixed rod is rotatably connected in a through hole in the middle of the supporting seat.

As a further improvement of the invention, the number of the cusps is more than two, and the cusps are symmetrically fixed below the supporting seat.

As a further improvement of the invention, a support piece is arranged on the swing arm;

the supporting piece comprises a containing seat fixed on the swing arm and a telescopic supporting rod connected with the containing seat; when the telescopic supporting rod is contracted, the telescopic supporting rod is contracted into the containing seat; when the telescopic supporting rod extends, the lower end of the telescopic supporting rod extends to the ground.

Compared with the prior art, the invention has the following beneficial effects:

the invention adopts the fixing (similar to fishing rod fixing) by inserting into the ground, and the fixing method is simple and firm. The staff of lifting the pole places the insulator spindle on the support can share most gravity like through the support, only needs less strength just can keep placing of the body of rod. Because the body of rod is not only dependent on the support at the pole lifting in-process, operating personnel can hold the body of rod always, consequently does not have the potential safety hazard.

The pull rod can be used for placing the pull rod when not in use, so that the pull rod is prevented from being placed on the ground to cause dirt and from directly falling down when placed against a wall.
