[0046] Embodiment 2. This embodiment is a further description of the special tool for hoisting tubular busbars described in Embodiment 2. In this embodiment, the connecting buckle includes a U-shaped arc 13-2 and a latch 13-1; The pin 13-1 passes through the two parallel faces of the U-shaped arc 13-2.

specific Embodiment approach 3

[0047] Specific embodiment three. This specific embodiment is a further description of the special tool for hoisting tubular busbars described in specific embodiment one. In this embodiment, it also includes a trip shaft limiter 7 and a trip shaft limit pin. Pin 8 and limit spring 11, the trip shaft limiter 7 is located on the trip shaft 4 between two rectangular steel plates to prevent the trip shaft 4 from falling off; the trip shaft limit pin 8 is used to fix the The position of the trip shaft limiter 7 is described; the limit spring 11 is sleeved on the trip shaft 4, and is located between the trip shaft limiter 7 and the rectangular steel plate close to the trip ring 4-1.

[0048] In this embodiment, the tripping shaft 4 is restricted by the tripping shaft limiter 7 and will not come out, preventing the tripping shaft 4 from falling off and damaging equipment and personnel, and the special lifting tool is separated from the pipe busbar to realize free tripping.

Abstract

The invention discloses a special tool for lifting a tubular bus bar and relates to the field of tubular bus bar lifting in the power industry. The special tool is designed for solving the problems of heavy workload, high working strength, high safety risk and low working efficiency in the existing method for lifting the tubular bus bar. The tool is formed by connecting a two-way regulator and a special lifting device; the length of a lifting rope is adjusted by a two-way adjusting bracket; the tubular bus bar is placed between a tripping shaft and a tripping device; the tripping shaft is fixed by a tripping device fixing ring, so that the tubular bus bar is suspended; after the suspended tubular bus bar reaches the designated position, a traction rope on a tripping ring is pulled, so that the tripping shaft is separated from the tripping device fixing ring, and the tubular bus bar is released. The special tool disclosed by the invention is suitable for the field of lifting.

Description

technical field [0001] The invention relates to the field of hoisting tubular busbars in the electric power industry. Background technique [0002] At present, when the tubular busbar (referred to as the tubular busbar) in the substation is hoisted, the lifting rope is directly tied to the lifting point of the tubular busbar, and the tubular busbar is hoisted at multiple points to make it evenly stressed. Lifting by one or more cranes. Since the friction force between the sling and the pipe mother is small and restricted by the angle of the sling, when the angle of the sling is too large, the lateral force on the sling will increase. When the lateral force of the sling is greater than the When there is friction between the pipe bus and the pipe bus, the lifting rope will slide along the axial direction of the pipe mother, thus changing the lifting point of the pipe mother and affecting the lifting quality of the pipe mother, so the angle of the lifting rope should not be to...
