Description
Technical field:
The present invention relates to a kind of isolating switch overhaul working platform, belong to the converting equipment service technique fields such as power system transformer substation isolating switch.
Background technology:
Isolating switch body works genus ascend operation, must tie safety belt.As isolating switch lifting or Disintegration overhaul, maintainer just must by safety belt colligation on isolating switch underframe and along with the transfer change colligation point of job site, and this will cause extending during check man, the risk that works increase.
Existing job platform is automobile mounted formula substantially, and volume is large, quality weight, and operating radius is large, because transformer station's station equipment is more, respectively into and out of line and fixture wire crisscross, working space is narrow and small, has very easily touched electric equipment when lifting, upkeep operation; Use existing job platform to carry out work often to cause power failure expanded range, interruption duration extends, the problems such as operating risk increase; Non-only like this, this type of equipment price is high, and maintenance expense is higher, virtually can increase job costs, be unsuitable for the maintenance of current transformer substation isolating switch, installation exercise.
Summary of the invention:
The object of the invention is to overcome the deficiency of above-mentioned prior art and provide that a kind of Financial cost is low, carrying and convenient storage, handsome in appearance, volume is little, lightweight, up and down balance system, safe and reliable, practical is strong, lifting can be played in minimum space and raise ability, be suitable for a kind of isolating switch overhaul working platform that in transformer station, mini-plant is installed, service work needs.
Object of the present invention can be reached by following measure: a kind of isolating switch overhaul working platform, it is characterized in that it comprises workbench part, scissor-type extension means, base portion, wherein workbench part comprises workbench, workbench side connects extendable platform, workbench connects guardrail, safety belt hanging beam, service work power supply, guidance panel, Work tool fixed case; Scissor-type extension means comprises inside and outside two groups of multistage X-type scissor arms, the upper end of multistage X-type scissor arm is connected with workbench by slide block, the lower end of multistage X-type scissor arm is connected by rocker bar bearing on the chassis of base portion, two hinges corresponding on multistage X-type scissor arm connect one end of two hydraulic cylinder legs respectively, two hydraulic cylinder leg other end connecting fluid cylinder pressures, hydraulic cylinder connecting fluid pressing system; Base portion comprises chassis, is provided with hydraulic system in chassis, and the lower end on chassis is provided with deflecting roller, and the side on chassis is provided with cat ladder.
The present invention can produce following good effect compared with the prior art: the present invention integrates the aerial work platform having installation, high-altitude maintenance, ladder, lifting and weight carrying function, adapt to the particular surroundings of substation field, overcome the related defects of existing equipment, Financial cost is low, carrying and convenient storage, easy and simple to handle, practical is strong, the jacking system of isolating switch overhaul working platform of the present invention adopts scissor-type mechanical structure, vertical lift, load-carrying is large, good stability; Four-wheel moves, and it is convenient to carry out.Have handsome in appearance, volume is little, lightweight, up and down balance system, the advantage such as safe and reliable, can play lifting and raise ability in minimum space, is suitable for that mini-plant in transformer station is installed, service work needs.The present invention has:
(1), present system is steady, and rise, decrease speed is even, in platform, worker safety is comfortable, ensures that workbench is reliable and stable.
(2), have extendable platform, can increase job area, mesa base steel plate is firm, has anti-skidding and from drain function.
(3), the built-in service work power supply of workbench, Work tool fixed case and safety belt hanging beam, ensure personal security in job platform.
(4), platform structure is firm, and operation is succinct, safe and efficient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment: the specific embodiment of the present invention is elaborated below in conjunction with accompanying drawing:
