Below by drawings and Examples, the technical solution of the utility model is described in further detail.
The spacing auxiliary supporting leg of elasticity of the present utility model can be arranged on the pedestal 2, and for pedestal provides support, shown in Figure 1 is the external structure of the spacing auxiliary supporting leg retracted state of elasticity.Fig. 2 has provided the structural representation of an embodiment of the spacing auxiliary supporting leg of the utility model elasticity.In the present embodiment, the spacing auxiliary supporting leg of elasticity comprises: orienting sleeve 6, sliding bar 4, auxiliary cylinder supporting leg 5 and elasticity position limiting structure 1, orienting sleeve 6 is installed on the pedestal 2, one end of sliding bar 4 and auxiliary cylinder supporting leg 5 are fixed and (are for example adopted the bolt fixed mode among Fig. 2, also can adopt welding, mode such as bonding), sliding bar 4 can stretch in orienting sleeve 6, elasticity position limiting structure 1 can be under the non-working condition of the spacing auxiliary supporting leg of elasticity that auxiliary cylinder supporting leg 5 is carried out elasticity is spacing, auxiliary cylinder supporting leg 5 is withdrawn under the non-working condition of the spacing auxiliary supporting leg of elasticity, stretches out under the use state and supports ground.
Can see that when sliding bar 4 was protruding with respect to pedestal 2, auxiliary cylinder supporting leg 5 also can be away from pedestal 2, and formed supplemental support on ground, and then provided more reliable and stable support for car load when the special operation condition operation.When sliding bar 4 was inwardly withdrawn with respect to pedestal, auxiliary cylinder supporting leg 5 was near pedestal 2, and minimizing takes up room.
It is spacing that elasticity position limiting structure 1 can carry out elasticity to auxiliary cylinder supporting leg 5, and this spacing referring to is in the non-working condition position restriction in following time at auxiliary cylinder supporting leg 5, prevents from that it from opening automatically because of reasons such as vibrations or deadweights to cause danger under non-working condition.
In Fig. 2, the stroke baffle 3 of limit slippage bar 4 can be set at an end of sliding bar 4, this stroke baffle 3 can be arranged on the inner end of orienting sleeve 6, can the sliding stroke of limit slippage bar in orienting sleeve by stroke baffle, and then restriction auxiliary cylinder supporting leg is away from the distance of pedestal, avoid the auxiliary cylinder supporting leg too away from pedestal, accordingly in the size outline of the inner end of orienting sleeve 6 less than stroke baffle 3, in order to realize the effect that stops.

In addition, can also adopt other structure, for example adopt the sliding bar of non-circular cross sections (as square cross section, rectangular cross section, oval cross section etc.), the inside face of orienting sleeve matches with sliding bar, sliding bar can only be with respect to the orienting sleeve telescopic slide, and can't swing in orienting sleeve.Accordingly, orienting sleeve can be designed to the structure that to rotate at pedestal, so just make sliding bar to rotate with the rotation of orienting sleeve.The pivot center of orienting sleeve is vertical with the auxiliary cylinder supporting leg, under the non-working condition of the spacing auxiliary supporting leg of elasticity, the auxiliary cylinder supporting leg is that axis turns to level attitude with the pivot center of orienting sleeve, and undertaken spacing by the elasticity position limiting structure, under the use state of the spacing auxiliary supporting leg of elasticity, the auxiliary cylinder supporting leg breaks away from the elasticity position limiting structure, and is that axis turns to vertical position with the pivot center of orienting sleeve.
Aspect elasticity position limiting structure 1, can adopt the elastic plate with boss, withstand auxiliary cylinder supporting leg 5 by the elasticity of boss, the elastic force that in the withdrawal of auxiliary cylinder supporting leg 5 and opening procedure, needs to overcome elastic plate, and need not to load and unload in withdrawal and opening procedure, therefore easy and simple to handle, safe and reliable.Interchangeable, the elasticity position limiting structure can also adopt thicker elastic wire with boss etc.
In addition, can arrange at the ground terminal of auxiliary cylinder supporting leg 5 and to have bigger area of contact, support more stable plectane 7, can certainly adopt for example sheet material such as square, pentagon of other shapes.
The spacing auxiliary supporting leg embodiment of above-mentioned elasticity is fit to be applied to the engineering mechanical device of all kinds of needs supporting legs, comprises that especially the freight container side of pedestal is from loading and unloading transport trolley.By adopting the spacing auxiliary supporting leg of elasticity, can make self-chambering unload transport trolley and become the spacing auxiliary supporting leg of elasticity by the flexible ground connection of original tire and contact with the ground rigidity, and also increase to some extent of span, whole vehicle stability increases greatly.
Three states below by the spacing auxiliary supporting leg embodiment of the utility model elasticity of Fig. 3-Fig. 5 from non-working condition to the state of use describe.
State shown in Figure 3 is the non-working condition of the spacing auxiliary supporting leg of elasticity, and under this state, sliding bar is fully retracted in the orienting sleeve, and auxiliary cylinder supporting leg level is horizontal on the supporting leg supporting construction, and is limited by the boss of elastic plate.
When needs use the spacing auxiliary supporting leg of elasticity, need the auxiliary cylinder supporting leg outwards be pulled out by manpower or equipment, overcome the elastic force of elastic plate, make it break away from supporting leg supporting construction, i.e. state shown in Figure 4.
When the auxiliary cylinder supporting leg is pulled outwardly when reaching to a certain degree, the stroke baffle of sliding bar can limit the auxiliary cylinder supporting leg can not continue outside stretching, the auxiliary cylinder supporting leg can be rotated about 90 degree this moment, make it perpendicular to ground, the piston rod of auxiliary cylinder supporting leg is stretched out, hold out against ground, i.e. state shown in Figure 5.Just can form reliable and stable support this moment.
