Technical field

The utility model relates to fall arrest lifesaving technical field of safety devices, especially relates to the safety device of the high pressure disconnecting link maintenance that is used for transformer station.

Background of invention

In transformer station's power transmission and transformation device of power system, its disconnecting link needs maintenance, need clean porcelain insulator, and component such as sleeve pipe need change, and these operations must be ascended a height, and ascend a height and need fasten the safety belt.But in zone, transformer station disconnecting link position, do not have firm high-order object, can be used to the place of hanging safety belt, the mode that adopts when the maintainer ascends a height sometimes is safety belt system to be hung on reinforcing bar mix on the support insulator of earth column top, and human body is climbed along column.Because support insulator is more crisp, insecure, thereby accident happens occasionally.Remove in the support insulator lead-in wire process as working as the maintainer together that Jing Zhou, Hubei electric company takes place the end of last year, from the root fracture, staff's porcelain vase falls with disconnecting link suddenly, and the disconnecting link moving contact is suppressed the personal injury in its chest death.State Grid Corporation of China's power transformation in the same year maintainer of company is when the old monarch's hall of 220kV transformer station maintenance disconnecting link, and support insulator from the root fracture, causes personal death by accident suddenly; To this, still there is not desirable solution so far.

Summary of the invention

The purpose of this utility model is in order to protect staff's personal safety; a kind of high pressure disconnecting link maintenance safety device is provided; make the maintainer of transformer station that the place that can hang safety belt be arranged when climbing support insulator; in climbing, promptly fasten one's safety belt, guarantee to climb personal security ground step and go up and safety and descending.

For achieving the above object, the technical solution of the utility model is such: a kind of high pressure disconnecting link maintenance safety device, a ladder main body is arranged, and the secondary ladder of being close to the ladder main body and can moving up and down along the ladder main body; Contact surface between the major-minor ladder has the male and female chute, and fastener is arranged, the locking after being used to locate; Front side, two ends up and down in the ladder main body, each fixedly connected anchor ear frame, the front crosspiece of this anchor ear frame is movable, the reinforcing bar of living support insulator below in order to frame mixes fixing behind the earth column, for strengthening mechanism's intensity, between anchor ear frame and ladder main body, be provided with diagonal cleat pole; For ease of moving, under anchor ear frame and ladder main body, be provided with 4 wheels, wherein two wheels in front are fast pulley, two wheels in back are universal wheel; Fix the cross section vertical rod of one " worker " font in the step of secondary ladder, this vertical rod is as guide rail, and it cooperates with fall arrest assembly, constitutes the ascend operation catching device; Said fall arrest assembly by I to national applications utility model patent, application number is: 200520100459.5, and it is formed by housing and with keep plate two parts that housing is hinged, and groove is arranged in the housing, wear guide rail in it, fall arrest assembly can slide up and down along guide rail; Keep plate can hinge be that rotate at the center, and its head is cam-shaped, and can contact connection with guide rail, and the keep plate afterbody has perforation, in order to fasten the safety belt and human body links, plays the high protective effect of fall arrest immediately.

Owing to adopted technique scheme, a kind of high pressure disconnecting link maintenance safety device of the present utility model, have that simple in structure, type body is light and handy, conveniently moving, safe and reliable characteristics, make the maintainer of transformer station existing place that hangs safety belt when climbing support insulator and maintenance, can guarantee when climbing safely step again and on and safety and descending.
