Description
Technical field
The utility model relates to aviation surface facility field, says it is a kind of lifting table car owner platform jack up unit that is used for the aircraft cargo loading and unloading in detail.
Background technology
As everyone knows, lifting platform truck carries out goods by main lifting platform and bridge platform or tray carriage and transmits, and is the aircraft handling goods.
At present, use more lifting table car owner platform jack up unit to be: to be provided with inside and outside shear shank below the platform framework, wherein Xia Mian a pair of ear seat is hinged on the vehicle frame, top a pair of ear seat is hinged on the platform framework, chain one end is fixed on the vehicle frame, and the other end connects platform framework, is fixed on column hydraulic ram on the vehicle frame by the bottom, by the pulley jacking chain above the piston rod, the lifting of pulling platform framework.Be characterized in: rising or falling speed is fast, the efficient height.Its deficiency is: the column hydraulic ram is located at the platform framework both sides, lifting platform truck change width difficulty, and the bulky and piston rod of column hydraulic ram exceeds platform framework, collision column hydraulic cylinder piston rod and chain easily during the goods alongside transfer.
Because there is lifting platform truck change width difficulty in existing lifting table car owner platform jack up unit, bulky and the piston rod of column hydraulic ram exceeds platform framework, the deficiency that bumps easily during the goods alongside transfer, have significant limitation during use, can not satisfy lifting table car owner berm width change convenient, the hydraulic ram volume is little, the requirement that is difficult for bumping during the goods alongside transfer.
Summary of the invention
There is lifting platform truck change width difficulty in order to overcome existing lifting table car owner platform jack up unit, bulky and the piston rod of column hydraulic ram exceeds platform framework, the deficiency that bumps easily during the goods alongside transfer, the purpose of this utility model is the main platform jack up unit of lifting platform truck is improved, becoming the lifting of column hydraulic ram chain is the jack-up hydraulic ram and the hydraulic ram jacking that hoists, satisfying lifting table car owner berm width changes conveniently, the hydraulic ram volume is little, the requirement that is difficult for bumping during the goods alongside transfer.
The utility model adopts following technical solution: a kind of lifting table car owner platform jack up unit, comprise inside and outside shear shank, it is characterized in that: the lower hinge of the hydraulic ram that hoists is in interior shear shank bottom, the liquid cylinder piston bar is hinged on the outer shear shank upper beam bearing, the jack-up hydraulic ram and the hydraulic ram that hoists are worked simultaneously, the bottom of jack-up hydraulic ram is fixed on the vehicle frame, and hydraulic pressure pole top is unsettled, and jack-up hydraulic ram is a multi-stage oil cylinder.
Respectively be provided with one about described jack-up hydraulic ram.
The described hydraulic ram that hoists is two oil cylinder parallel connections.
The beneficial effects of the utility model are: owing to adopt jack-up hydraulic ram and hoist the hydraulic ram jacking, above the platform framework and side is without any stopping, the hydraulic ram size reduces significantly, satisfying lifting table car owner berm width changes conveniently, the hydraulic ram volume is little, the requirement that is difficult for bumping during the goods alongside transfer, flexible and convenient to use.The utility model can be used for the main lifting platform of lifting platform truck.
Description of drawings

Fig. 2 is the high-order scheme drawing of the utility model lifting table car owner platform jack up unit.
Fig. 3 is in the scheme drawing of high-end trim for the utility model platform framework.
Among the figure, 1. platform framework, 2. in shear shank, 3. hydraulic pressure pole, 4. hydraulic ram, 5. hydraulic ram, 6. liquid cylinder piston bar, 7. vehicle frame, 11. outer shear shanks.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, lifting table car owner platform jack up unit of the present utility model is described further, to help to understand content of the present utility model.
In Fig. 1, shear shank 2 and outer shear shank 11 are hinged in being provided with below the platform framework 1, the a pair of ear seat of its middle and lower part fwd is hinged on the vehicle frame 7, the a pair of ear seat of upper front is hinged on the platform framework 1, jack-up hydraulic ram 4 bottoms are fixed on the vehicle frame 7, hydraulic pressure pole 3 tops are unsettled, and jack-up hydraulic ram 4 is a multi-stage oil cylinder; On the shear shank 2, liquid cylinder piston bar 6 was hinged on the upper beam bearing of outer shear shank 11 in the hydraulic ram 5 that hoists was hinged on, and the jack-up hydraulic ram 4 and the hydraulic ram 5 that hoists are worked simultaneously.
Jack-up hydraulic ram about 4 respectively is provided with one.The hydraulic ram 5 that hoists is two oil cylinder parallel connections.
When hoisting, the jack-up hydraulic ram 4 and the hydraulic ram 5 that hoists are worked simultaneously, jacking hydraulic pressure pole 3 directly withstands on the bottom of platform framework 1, and by the platform framework 1 outer shear shank 11 of pulling and interior shear shank 2 on increase the angle of hoist hydraulic ram 5 and horizontal surface, thereby increase sharply the vertical component that hydraulic ram 5 makes progress that hoists, jacking hydraulic pressure pole 3 drives platform frameworks 1 with raising cylinder piston rod 6 common outer shear shanks 11 of promotion and interior shear shank 2 to be risen, and enters effective working load district of the hydraulic ram 5 that hoists.
In Fig. 2, Fig. 3, after the hydraulic ram 5 that hoists enters effective working load district, jacking hydraulic pressure pole 3 breaks away from platform framework 1, shear shank 2 and outer shear shank 11 drive platform frameworks 1 continued to rise in raising cylinder piston rod 6 promoted, jacking hydraulic pressure pole 3 tops are unsettled, jack-up hydraulic ram 4 quits work, and the hydraulic ram 5 that hoists works independently, and shear shank 2, outer shear shank 11 drove platform framework 1 and rise to assigned address in raising cylinder piston rod 6 promoted.Vehicle frame 7 is maintained fixed.
During decline, reversed in order.
The utility model can be used for lifting table car owner lifting platform.
