Abstract

The invention discloses a single-hook lifting device for a switch blade porcelain insulator. The single-hook lifting device comprises a lifting hook, a power mechanism, a suspension arm, a first support rod, a limitator, a first fixing device, a second support rod and a cross rod, wherein one end of the second support rod is vertically fixed on a switch blade bracket through the first fixing device; two ends of the cross rod are fixed on two switch blade constant-diameter rods, and the cross rod is fixed with the other end of the second support rod; the lower end of the first support rod is inserted into the second support rod, and is fixed with the second support rod through the limitator; one end of the suspension arm is rotationally fixed at the top end of the first support rod through a bearing; and the power mechanism is fixed at the end part of the other end of the suspension arm, and the lifting hook is arranged on the power mechanism. The single-hook lifting device can be used in a finite space, is simple and convenient to adjust in height, ensures the safety and the reliability in lifting the switch blade porcelain insulator, has a high operating efficiency, and solves the difficult problem that lifting cannot be carried out since the safety distance between a crane and electrified equipment on a reformation site is not long enough.

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to a single-hook hoisting device for a gate-knife porcelain vase. Background technique [0002] In the power system, the switch blades in the substation are seriously corroded and have more defects due to the longer operating time, which seriously affects the reliability of power supply, so it is urgent to carry out corresponding transformation. [0003] In the process of transformation, in order not to affect the power supply of users, it is usually adopted that some intervals are powered off for reconstruction, and other intervals are powered on. In such an operation mode, it is often encountered that the switch knife that needs to be modified is too close to the live equipment, which cannot meet the sufficient safety distance required for hoisting by the on-site crane, resulting in difficulty in hoisting, or even impossible hoisting. The transformation can only...
