Problems solved by technology

[0003] At present, in the crimping construction of the splicing tubes of transmission lines, wooden sticks, mallets or even metal tools are still used to straighten the bent and deformed splicing tubes, which may cause the splicing tubes to be twisted and deformed, and the splicing tubes to appear Cracks or internal damage; if the percussion force is too strong, it will also cause the connecting pipe to bend in the opposite direction, causing secondary damage to the connecting pipe, so it is difficult to guarantee the quality and process of bending and straightening of the connecting pipe
Also, if the bent nipple has been lifted into the air, it is not possible to straighten the nipple by tapping

Abstract

The invention relates to an adjustable bending straightening tool for a power transmission line splicing sleeve and belongs to the technical field of power transmission line splicing sleeve straightening. The tool comprises a straightening cross beam, a straightening force-bearing screw rod, straightening force-bearing hooks and a limiting rod; a plurality of straightening force-bearing hook fixing screw holes are uniformly distributed in the straightening cross beam; a force-bearing screw rod nut is mounted on the straightening cross beam; the straightening force-bearing screw rod comprises aratchet wrench, a force-bearing screw rod and a base; each straightening force-bearing hook comprises a fixing screw rod matched with a straightening force-bearing hook fixing screw hole; each straightening force-bearing hook further comprises a fixing hook; a limiting rod hole matched with the limiting rod in size is formed in each fixing hook; and each fixing hook is provided with a limiting rod locking bolt. The tool is adjustable; the installation position of the straightening force bearing hook can be adjusted, so that the tool can adapt to the straightening of deformed splicing sleeveswith different lengths and different bent parts. The straightening tool is light, universal and easy to operate; and the straightening tool can be used for ground splicing sleeve bending straighteningand can also be used for high-altitude straightening; and the straightening tool is easy to apply and popularize.

Description

technical field [0001] The invention belongs to the technical field of straightening pipes for power transmission lines, and in particular relates to an adjustable bending straightening tool for connecting pipes of power transmission lines. Background technique [0002] The joints of the transmission line conductors and ground wires are all hydraulically connected by connecting pipes. During the crimping process, if the die used in the hydraulic pressure does not match the connecting pipes, or the grounding wires and the connecting pipes are not kept horizontal during crimping, If it is not consistent with the axis of the hydraulic press, it will cause the connecting pipe to bend after being compressed. In general, the longer the connecting tube, the narrower the width of the die, the more the modulus of crimping, the greater the bending degree, and the visible deformation within the range of less than 2% bending deformation should be straightened. [0003] At present, in t...
