Description
Technical field
The utility model relates to a kind of airport elevating platform car, and specifically a kind of airport elevating platform car self-reset oscillation back axle, is mainly used in the large transport airplane goods and materials loading/unloading platform of airport lifting mode.
Background technology
Goods and materials loading/unloading platform is one of main ground service equipment in airport, because its working environment is mainly airport pavement, for meeting need of work, chassis height design very low, the ground Clearance is generally very little, road surface comformability and off-road capability very poor.
Because this equipment needs to adapt to non-airport pavement and air strip road traveling needs, and the requirement of demand fulfillment accompanying support, possess the ability of large transport airplane up and down voluntarily, climbable gradient is not less than 16 °.When this platform truck is boarded a plane, as sailed into by working direction, anterior operator's compartment may occur to touch to push up to lose efficacy with aircraft door, and therefore employing is poured method into and sailed cabin into, but platform truck rear portion departure angle is less, may occur to touch tail lost efficacy with aircraft sloping platform.
Summary of the invention
Little in order to solve the platform vehicle chassis ground Clearance, crossing ability is poor, cannot meet the problem of off-road capability and climbable gradient requirement, and the utility model provides a kind of airport elevating platform car self-reset oscillation back axle.By the variable chassis special of design crossing ability, ensure platform truck carry out accompanying support voluntarily up and down large transport airplane time, increase its departure angle, meet its air transportation requirement.
The utility model is by the following technical programs: a kind of airport elevating platform car self-reset oscillation back axle, comprises vehicle frame and is arranged on the platform on vehicle frame; Described vehicle frame front end is provided with front-wheel, and rear end is provided with breast wheel and trailing wheel successively; Described vehicle frame rear end is hinged with turret; Equalizing bar soldering member is furnished with in described vehicle frame bilateral symmetry; Described equalizing bar soldering member is between breast wheel and trailing wheel, and breast wheel is arranged on equalizing bar soldering member front end, and trailing wheel is arranged on equalizing bar soldering member rear end; Equalizing bar soldering member rear end and turret hinged, the hinge-point place of equalizing bar soldering member and turret is provided with the turret block limiting and relatively rotate angle between them; Be hinged with auxiliary lifting oil cylinder in the middle part of equalizing bar soldering member, described auxiliary lifting cylinder upper end withstands on platform lower surface.
It is further: the cylinder body of described auxiliary lifting oil cylinder is hinged on equalizing bar soldering member, and the piston rod end of auxiliary lifting oil cylinder is against platform lower surface; The piston rod end of described auxiliary lifting oil cylinder, in outstanding circle, is fixed with the support round slip surface coordinated with auxiliary lifting oil cylinder piston boom end at platform lower surface.
Described auxiliary lifting oil cylinder is restricted to each 3 degree around along hinge-point rotational angle; A pull back spring is respectively connected with between the auxiliary lifting oil cylinder left and right sides and equalizing bar seam.
Described auxiliary lifting oil cylinder connects into platform truck hydraulic efficiency pressure system, and the control setup of auxiliary lifting oil cylinder is placed on operator's compartment.
Groundwork feature of the present utility model is: lowest order fallen by vehicle frame in normal state, the low good stability of center of gravity, and symmetrical expression equalizing bar soldering member makes middle back axle carry evenly, meets job requirements.In this case, ramp breakover angle and departure angle less, by poor performance, as shown in Figure 1.When light condition is climbed, or need by under non-good surface conditions, by the shaft swing of auxiliary lifting oil cylinder pushing turret around vehicle frame rear portion, equalizing bar soldering member rotates around turret axle, thus vehicle frame rear end is held up, equalizing bar soldering member is under the position-limiting action of turret block, also can along with turret be around the swing of the rotating shaft generation certain angle at vehicle frame rear portion, as shown in Figure 2, thus platform departure angle is increased, ramp breakover angle also increases to some extent, improve crossing ability, meet the requirements such as climbing, particularly meet the needs of this platform truck upper and lower large transport airplane voluntarily.When not needing to promote Rear frame, make auxiliary lifting oil cylinder return by hydraulic control system, under gravity, Rear frame falls automatically, and the wheel ground connection simultaneously of back axle both sides, reaches state shown in Fig. 1, form the back axle of self-reset oscillation.
Main beneficial effect of the present utility model is: adopting can the swing back axle of Self-resetting, make large transport airplane goods and materials loading/unloading platform in climbing with by under non-good surface conditions, by raising the ground Clearance of Rear frame and rear wheel, thus improve the ground Clearance of complete machine, platform departure angle is made to reach 38 °, car load is not less than 16 ° by angle, greatly improve crossing ability, make it possess non-airport pavement, air strip road surface operational capability, meet the air transportation requirement of this platform truck upper and lower large transport airplane voluntarily.
The major advantage of this structure is:
1. auxiliary lifting oil cylinder adopts platform truck hydraulic efficiency pressure system power, without the need to separately establishing propulsion source;
2. make vehicle frame rise makes trailing wheel rise simultaneously, and departure angle increases significantly, and crossing ability increase rate is large;
3. structure is simple, reliable operation, and efficiency is high;
4. simple to operate, efficient and convenient.
