Description
Technical field
The present invention relates to power domain, more particularly to breaker transportation trolley.
Background technology
The interruption maintenance mode of operation of 10kV middle truck breaker of switch cabinet is in current power network：Breaker division can be by the straighforward operation of distant place control centre, turnover handcart circuit breaker is needed after power failure of breaker, it is manually withdrawn into testing position by run location by operation operating personnel to switch gear room's onsite application rocking handle, then by breaker of switch cabinet is removed outside switch cubicle by service trolley.In the process, service trolley plays very important effect, operations staff needs to adjust the whole height of service trolley and the smoothness of dolly according to the height of breaker, existing service trolley with highly adjust inconvenient in switch cubicle docking operation, general height of the factory with service trolley is adjusted by four rotary screws of trolley base, need repeatedly to adjust repeatedly, governing speed is slow, valuable time is wasted during regulation, it is difficult the balance for accomplishing corner during regulation simultaneously, cause breaker to be difficult to move on dolly or make breaker unstable on service trolley, so easily promote the rollover of breaker, so as to damage breaker or cause casualties.The such situation of generation will cause equipment out of service, cause unnecessary loss of outage, have a strong impact on the reliability of operation of power networks.Install the power distribution room of 10kV middle-placed switch cabinets, typically two kinds of breaker transportation trolleys of configuration.It is a kind of higher（Suitable for into and out of line cabinet）, it is another relatively short（Suitable for PT, metering cabinet）.It is conventional to turn screw for hand.Employment is needed to go to rotate screw rod, it is less efficient and waste time and energy, have much room for improvement.
The content of the invention
The present invention is in view of the shortcomings of the prior art, it is easily operated there is provided one kind, it is safe and reliable, and be widely applicable on transformer station 10kV voltage class central switch cabinets, under the premise of 10kV center switch cabinet breaker functions are not influenceed, the foot-pedal hydraulic type breaker transportation trolley of its service trolley security reliability is improved.
To realize the object of the invention, there is provided following technical scheme：Foot-pedal hydraulic type breaker transportation trolley, including car body, car body includes bottom plate, it is arranged at the wheel of bottom plate bottom surface, with the vertically disposed support frame of bottom plate, platform and the handrail on support frame top are operated with the vertically disposed breaker of support frame, it is characterized in that support frame is arranged at bottom plate one end and is symmetrical two, the corresponding surface center of two support frames longitudinally offers the strip notch that section is dove-tail form, breaker operating platform both sides are provided with the projection being coupled with strip notch, both coordinate slides along strip notch, below breaker operating platform, hydraulic jack is provided with bottom plate between support frame, the piston rod of hydraulic jack is straight up, piston-rod end is connected with support meanss, support meanss are fixedly connected with breaker operating platform base, bottom plate end is provided with pedal, pedal electrically connects hydraulic jack.
As preferred, support meanss include cylindrical central sleeve and the stiffener plate radially distributed around bushing core, through hole is offered on cylindrical central sleeve barrel, the piston rod for setting bolt presses to insert in cylindrical central sleeve in through hole, the stiffener plate, cylindrical central sleeve and breaker operating platform base are welded and fixed.
Beneficial effect of the present invention：The height of transportation trolley can be arbitrarily adjusted using foot-pedal hydraulic type breaker transportation trolley, and is got off without configuring two, so as to realize the multi-purpose purpose of a car.Transportation trolley elevating board uses foot-pedal hydraulic type, and screw is turned instead of conventional hand.Not employment surrounding goes to rotate screw rod, convenient and swift as long as gently stepping on hydraulic plate with pin with regard to that can raise transportation trolley.After being improved to breaker transportation trolley, the power distribution room of installing 10kV middle-placed switch cabinets only needs to one transportation trolley of configuration with regard to that can meet demand.
