A horizontal lifting tooling for the interrupter chamber of tank type circuit breaker

Abstract

The invention relates to a horizontal hoisting fixture for a tank type circuit breaker arc extinguish chamber. The horizontal hoisting fixture comprises a connection frame connected with a cover plate of the arc extinguish chamber and a balance weight mounted on one side, which is far away from the cover plate, of the connection frame, wherein an adjustment hoisting structure which is connected with a hoisting mechanism so as to be cooperated with a main hoisting point of the arc extinguish chamber to level the arc extinguish chamber is arranged on the connection frame and / or the balance weight; and the adjustment hoisting structure comprises a threaded adjustment mechanism capable of adjusting a distance between the adjustment hoisting structure and the hoisting mechanism. According to the horizontal hoisting fixture for the tank type circuit breaker arc extinguish chamber, when the upper part, serving as the main hoisting point, of the cover plate of the arc extinguish chamber is used for carrying out hoisting, the arc extinguish chamber may still be slightly inclined and not leveled completely; at the moment, the threaded adjustment mechanism, which is connected with the hoisting mechanism through a hoisting rope, of the adjustment hoisting structure is used for fine adjustment, so that adjustment of leveling hoisting of the arc extinguish chamber is greatly facilitated, the hoisting progress is accelerated, and the working efficiency is improved; and the problem that levelness of the arc extinguish chamber is very difficult to adjust during level hoisting of the tank type circuit breaker arc extinguish chamber is effectively solved.

Description

technical field [0001] The invention relates to a horizontal hoisting tool for an arc extinguishing chamber of a tank type circuit breaker. Background technique [0002] When the tank-type high-voltage circuit breaker arc extinguishing chamber is assembled, the outer cylindrical shell is placed horizontally, and the arc extinguishing chamber with a cover plate at one end needs to be hoisted into the shell. The high-voltage circuit breaker arc extinguishing chamber is heavy (1- 2 tons), need to be lifted by crane. Since the arc extinguishing chamber of the high-voltage circuit breaker is cylindrical as a whole, one end of the cylinder is connected to the cover plate. When lifting the arc extinguishing chamber horizontally, if the attached figure 1 As shown, the structure schematic diagram of the traditional hoisting tool for hoisting, its main body is to connect a lifting frame 8 on the cover plate 31, and the lifting frame 8 protrudes an L-shaped boom 81 upwards, after the ...
