Embodiment Construction

[0015] The following will be described in conjunction with the accompanying drawings and a specific embodiment.

[0016] see Figure 1 to Figure 3 . The transformer fall prevention device described in this embodiment includes two support rods 2 made of hollow steel pipes, and the lower end of each support rod 2 is provided with a gripper 3, which is a three-head gripper. The grab card 3 is equipped with a rotating bayonet pin 4 . The grab card is used to clamp the whole device on the edge of the transformer table. The grab card is concave, and the opening is located on the side. The specific shape is that the grab card includes an upper base plate, a lower base plate and a side plate connecting the upper and lower base plates. A screw hole is arranged on the upper base plate or the lower base plate, and a rotating bayonet 4 is assembled on the screw hole. The specific structure of the three-head grab card is as follows, including a center grab card, a pair of grab cards are...

Abstract

The invention discloses a falling-preventing device for a transformer. The falling-preventing device comprises two supporting rods. The lower end of each supporting rod is provided with a grabbing clamp. The upper ends of the two supporting rods are connected through a steel wire rope. The grabbing clamps are provided with rotating bayonet locks. The falling-preventing device is simple in structure, easy to operate, and high in flexibility and practicality. The detachable falling-preventing device is erected manually, the lower portion of the falling-preventing device is fixed to the edge of a table board of the transformer through the three-head grabbing clamps, the rotating bayonet locks are assembled on the grabbing clamps, the three-head grabbing clamps are connected firmly, and the stress is uniform; integrated hollow steel pipes are adopted in the upper ends of the grabbing clamps, and the height of the steel pipes is two meters; the two steel pipes are connected through the steel wire rope, safety belts of maintenance personnel are connected to the steel wire rope, the falling-preventing effect is achieved, and therefore the safety of operators is guaranteed.

Description

technical field [0001] The invention relates to electric maintenance safety protection equipment. Background technique [0002] The power transformer is an important substation equipment in the power system. Its operating status directly affects the safety of the system. With the rapid development of ultra-high voltage and ultra-high voltage power transmission and transformation technology, the capacity of the power grid is increased and the coverage is expanded. Its failure may affect the power The system and users have caused great harm and influence, how to efficiently and safely overhaul the transformer has become an urgent problem for us to solve. [0003] During the maintenance of transformers, the maintenance personnel need to climb the ladder to operate on the table. Since the height of the work table is more than 2m, according to the "Electricity Safety Work Regulations", the operation above 2m is a high-altitude operation, and the safety belt must be attached. The...
