Technical field
The utility model relates to a kind of top car device, particularly top car device.
Background technology
Jack is that a kind of the top with rigidity lifted part as equipment, through the light little weight-lifting equipment of top bracket or bottom claw jacking weight in stroke.Can be divided into 3 kinds of rank-and-pinion jack, lifting screw and hydraulic jacks by architectural feature.Jack is the simplest weight-lifting equipment of a kind of lifting highly little (less than 1m).It has two kinds of mechanical type and fluid pressure types.The mechanical type jack has rack-and-pinion and spiral two kinds again, because hoisting capacity is little, the operation effort generally only is used for flight-line maintenance work, and is inapplicable in repairing the bridge process.
Screw thread from falling lifting screw does not have self-locking action, and drg is housed.The loosen the brake device, weight can descend voluntarily fast, shortens return trip time, but this jack structure is complicated.
The utility model content
The technical matters that the utility model will solve provides a kind of good airproof performance, is convenient to dismounting and has self-locking makes top car device.
For achieving the above object, the technical scheme of the utility model is following:
Top car device, the control apparatus that said top car device comprises top board, is placed in the screw mandrel of top board lower end, the strut that is used to place screw mandrel, passive base plate and is used for regulating top car device height; Said control apparatus comprises ratchet assembly, surface bearing and handle, and said handle is connected with ratchet assembly is rotating, and an end of said handle is provided with plain cushion and spring cotter; Said surface bearing is placed in the lower end of ratchet assembly, and said surface bearing is through nut and bolt; The outside of said surface bearing is provided with the bearing core retainer plate, and said surface bearing is provided with key; Said ratchet assembly is provided with alemite.
Preferably, said ratchet assembly comprises free wrench, ratchet, ratchet sleeve and mandrel, and said ratchet is connected with free wrench, and said ratchet sleeve is placed in the ratchet outside, and said mandrel is placed in the ratchet assembly, and said mandrel one end is provided with spring.
Preferably, said top car device also comprises at least two reinforced ribs; One end of said reinforced rib is connected with strut, and the other end is connected with base plate.
Through technique scheme, the beneficial effect of the utility model is:
The utility model adopts ratchet assembly to regulate top car device height, and it has the effect of automatically locking; The utility model adopts surface bearing to seal its good sealing effect; Be provided with reinforced rib between the utility model base plate and the strut, its safety performance is high, can support weight for a long time.
