Description
Technical field
The utility model relates to a kind of manufacturing equipment of power transmission and transformation, relates in particular to the running dolly of the switch cubicle of joining the middle circuit breaker cart.
Background technology
The running dolly of joining the switch cubicle of middle circuit breaker cart because the running dolly often need raise or reduce, reaches at the height that is fit to, so that circuit breaker cart is pushed in the switch cubicle circuit breaker cart.The middle switchgear running dolly of prior art is to shake the lifting that pallet is controlled in the screw mandrel transmission by handwheel.Because the middle circuit breaker is heavier, handwheel shakes harder, inconvenient operation, and lifting is not steady, and fail safe is not high.In addition, the screw mandrel transmission also is very easy to damage under the effect of gravity.
The utility model content
The purpose of this utility model provides a kind of middle switchgear running dolly, its simple speed easy to adjust is fast, and the high conformity of regulating, increase horizontal jacking equipment function, the governor motion self-locking, thus reach simply, effect fast, can more convenient circuit breaker cart be pushed in the cabinet by the running car, and safe, good reliability, the scope of application is wide.
The technical scheme that technical problem adopted that the utility model solves is: a kind of middle switchgear running dolly, the base that comprises supporting plate and belt wheel, it is characterized in that: be provided with two support shelves that are hinged of intersection between supporting plate and base, two ends of supporting shelves one sides are hinged with supporting plate, base respectively, two ends of supporting the shelves opposite side are connected with pallet guide, base rail respectively, are hinged with hydraulic cylinder in it and between the top of the hinged support shelves of base and the base.During concrete the use, flexible by the regulator solution cylinder pressure controlled the lifting of supporting plate, and when hydraulic cylinder stretches out, two are supported the ends that shelves are connected with pallet guide, base rail and move the supporting plate rising to the middle part of the dolly that turns round in track; When the cylinder pressure contraction, two are supported grade ends that are connected with pallet guide, base rail and move supporting plate decline to the sidepiece of running dolly in tracks.
During concrete enforcement, the junction guide rail of the end of two support shelves and supporting plate, base comprises roller and track, and roller is located at two ends of supporting shelves respectively, and track is located at respectively on the supporting plate and base of corresponding position.
Usually hydraulic cylinder adopts hydraulic jack, can by the hydraulic system transmission, lift part with cylinder body or piston as the top by manpower or driven by power hydraulic pump.Hydraulic system utilizes hydraulic pump the mechanical energy of prime mover to be converted to the pressure energy of liquid, energy is transmitted in variation by the fluid pressure energy, transmission through various control valves and pipeline, can be converted to mechanical energy to fluid pressure by means of hydraulic actuator, thereby drive operating mechanism, realize straight reciprocating motion and gyration.
Hydraulic jack rises and can adopt handle adjusting or pin to step on multiple modes such as adjusting.
During concrete enforcement, be connected with handle on base, the handle bottom is provided with pedal, and handle top is provided with action bars, the pressure handle interlock of pedal and hydraulic jack, the break valve interlock of action bars and hydraulic jack.With common hydraulic jack is example, and operation principle is: when pedal upwards lifts, drive piston stroking upward, closed check valve, the swept volume of piston cylinder enlarges and forms vacuum, and under atmospheric effect, the liquid in the fuel tank is opened unidirectional valve through oil pipe and flowed in the piston cylinder; When depressing pedal, drive descent of piston, closed check valve, the fluid in the piston cylinder is pushed unidirectional valve open, and fluid enters plunger case, and plunger is risen, the acting of jack-up weight.When the need plunger stops, stopping the depression bar motion, the oil pressure in the plunger case makes closed check valve, and the plunger self-locking is motionless; When needing plunger to return downwards, action bars is opened break valve, and under a downward external force effect, plunger can reset.
The utility model is adopted as the hydraulic drive lifting technology, realizes the lifting and the accurate lock function of equipment.The steady lift action of hydraulic jack jack-up, two of symmetry are supported shelves and make supporting plate not produce deflection when lifting.
The beneficial effects of the utility model are: owing to adopt the hydraulic drive lifting technology, having characteristics such as lifting is steady, easy to operate, safe and reliable, is the ideal tools that reduces labor intensity, enhances productivity, realizes the breaker safe transhipment.
