Summary of the invention:
The object of the invention is to overcome the deficiency of above-mentioned prior art and provide one to realize on-the-spot 10kV armored mid-set metal closed switch cabinet overhaul of line breaker, rise and fall and move, save cost of labor, reduce security risk, the adjustable dedicated hydraulic moving lifting car of increasing work efficiency.,
Order of the present invention can be reached by following measure: a kind of adjustable dedicated hydraulic moving lifting car, it comprises body groove steel bracket, body groove steel bracket lower end connects base, it is characterized in that base lower end is provided with directed roller, base is flexibly connected maintenance support, body groove steel bracket connects slider roller, slider roller connects hydraulic pressure conduction chain, hydraulic haulage chain connects hydraulic lifting oil cylinder, hydraulic lifting oil cylinder connects manual lifting rod respectively, foot-propelled lifting is stepped on, relief valve, the two ends of slider roller connect a hoisting bracket respectively, each hoisting bracket is equipped with equally distributed connecting hole, connecting hole on two hoisting brackets is corresponding, wherein two corresponding connecting holes connect an adjustable suspension hook respectively, two hoisting brackets are connected with the two ends of horizontal inside and outside mobile leading screw respectively, laterally one end of inside and outside mobile leading screw connects adjustment runner, the both sides of the axis of guide connect hoisting bracket respectively by the sliding tray on it.
In order to realize object of the present invention further, described base connecting pin touches on the brake device, stop screw.
In order to realize object of the present invention further, described body groove steel bracket rear end connects handrail.
The present invention can produce following good effect compared with the prior art:
1, the present invention utilizes hydraulic principle, and 4 directed rollers are installed in bottom, and adds and turn a steered wheel, just can meet hydraulic moving lift truck space in different and move.Eliminate artificial carrying, reduce security risk, increase work efficiency.
2, the present invention utilizes the cooperation of hydraulic mechanism and conduction chain, and welding and assembling height support just can meet the lifting of certain altitude range devices, completes rising and falling and moving of breaker apparatus.
3, the present invention installs hand wheel additional at horizontal inside and outside mobile leading screw, is regulated, can realize the adjustment of different in width circuit breaker in allowed band by the rotation of runner, eliminates a transformer station and need configure many different moving lifting special-purpose vehicles, saved cost.
The movement that the present invention is possessed by it, lifting, adjustment three zones, reach the carrying of middle circuit breaker, only need 2 people just can carry out continuous productive process, substantially increase efficiency of construction, and circuit breaker can be lifted on lift truck support and carry out chassis maintenance, simple to operate, light and fast, eliminates potential safety hazard, ensure that the premium properties of equipment.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the end view of Fig. 1.
Embodiment: preferred forms of the present invention is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of adjustable dedicated hydraulic moving lifting car (see Fig. 1, Fig. 2), it comprises body groove steel bracket 16, body groove steel bracket 16 lower end connects base 19, rear end connects handrail 1, base 19 lower end is provided with 4 directed rollers 10, and base 19 connects two pin and to touch on the brake device 5, base 19 is flexibly connected maintenance support 6, support 6 is collapsible rises and falls in maintenance, base 19 connects stop screw 14; Body groove steel bracket 16 connects slider roller 17, slider roller 17 can slide up and down on body groove steel bracket 16, and slider roller 17 connects hydraulic pressure conduction chain 2 by connecting bolt 20; Hydraulic haulage chain 2 connects hydraulic lifting oil cylinder 13, and hydraulic lifting oil cylinder 13 is connected on base 19, hydraulic lifting oil cylinder 13 connects respectively manual lifting rod 3, foot-propelled lifting steps on 4, relief valve 15; The two ends of slider roller 17 connect a hoisting bracket 7 respectively, each hoisting bracket 7 is equipped with equally distributed connecting hole 18, connecting hole 18 on two hoisting brackets 7 is corresponding, wherein two corresponding connecting holes 18 connect an adjustable suspension hook 9 respectively, adjustable suspension hook 9 needs to determine with which connecting hole 18 to be connected according to distance; Two hoisting brackets 7 are connected with the two ends of horizontal inside and outside mobile leading screw 12 respectively, and laterally one end of inside and outside mobile leading screw 12 connects adjustment runner 8.The both sides of the axis of guide 11 connect hoisting bracket 7 respectively by the sliding tray on it, and hoisting bracket 7 can slide on the axis of guide 11.
