Description
Technical field
The utility model relates to a kind of hand-hydraulic lifting device, packaged type hand-hydraulic lifting device specifically.
Background technology
At present; known semi-mounted bearing set is used widely in trailer; its function is mainly used when vehicle stationary state; by M/C, make trailer and tractor truck successfully throw off or articulate, in driving process, contingency tractor truck axle fracture can't play a protective role to trailer, therefore; the danger that material is tumbled occurs as just had in the transportation of molten iron in the material transportation important at some; for guaranteeing safety, at the front portion of heavy-duty trailer welding rigid leg, play the effect of safety guard-safeguard.
The operation that the semi-trailer transport trolley need to be thrown off tractor truck and superimposed trailer and articulate during et out of order in transportation, what because trailer is anterior, install is the welding rigid leg, self can't complete lift operation.
Summary of the invention
The utility model is intended to overcome the defect of prior art, and a kind of packaged type hand-hydraulic lifting device is provided, and superimposed trailer jack-up conveniently and with tractor truck can be broken away from and articulates.
In order to solve the problems of the technologies described above, the utility model is achieved in that
A kind of packaged type hand-hydraulic lifting device, it is characterized in that: it comprises footing, the single-acting hydraulic jack, the jack fixed mount, the inching cushion block, pretensioned spring, bracing frame, high pressure hose and manual pump, be provided with the single-acting hydraulic jack in described jack fixed mount, the bottom of jack fixed mount is connected with the bracing frame with cardan wheel, pretensioned spring all is equipped with on the top of each cardan wheel, footing is located at single-acting hydraulic jack top, the inching cushion block is located between single-acting hydraulic jack and jack fixed mount, manual pump is connected with the single-acting hydraulic jack by high pressure hose.
Described packaged type hand-hydraulic lifting device, it is characterized in that: it also comprises the adjustment cushion block, this adjustment cushion block is located between single-acting hydraulic jack and jack fixed mount.
Described packaged type hand-hydraulic lifting device is characterized in that: support frame as described above is triangular support bracket.
The beneficial effects of the utility model are: this device volume is little, convenient in carrying, can, from walking, on narrow road, also can use, O&M is simple, without other accessory equipment, save a large amount of manpower and materials during use, also greatly alleviated labour intensity.Can join many semi-trailer transpories trolley by a machine.Cost-saving.
The accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1: a kind of packaged type hand-hydraulic lifting device, it comprises footing 1, single-acting hydraulic jack 2, jack fixed mount 3, inching cushion block 4, pretensioned spring 6, triangular support bracket 7, high pressure hose 9 and manual pump 10, be provided with single-acting hydraulic jack 2 in described jack fixed mount 3, the bottom of jack fixed mount 3 is connected with the triangular support bracket 7 with cardan wheel 8, pretensioned spring 6 all is equipped with on the top of each cardan wheel 8, footing 1 is located at single-acting hydraulic jack 2 tops, inching cushion block 4 is located between single-acting hydraulic jack and jack fixed mount, manual pump 10 is connected with single-acting hydraulic jack 2 by high pressure hose 9, it also comprises adjusts cushion block 5, this adjustment cushion block 5 is located between single-acting hydraulic jack and jack fixed mount, adjust the height of cushion block 5 by the jacked object body, the height of single-acting hydraulic jack determines, if short just the increasing of the stroke of single-acting hydraulic jack adjusted cushion block 5.During without pretensioned spring, can promote by universal caster wheel, during use, the further compression of pretensioned spring meeting bracing frame lands and can realize lifting.
