In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
The trolley supporting mechanism including folding ram and cushion block and is located at the supporting block of trolley longeron lower part, the folding
Folded cylinder upper end is hinged with longeron lower part, and cushion block top is hinged with supporting block lower end by axis pin, the side of cushion block and folding
The lower end of folded oil cylinder is hinged；The supporting block and cushion block are being equipped with locating slot on pin roll end face side, in supporting block
Locating slot on locating slot and cushion block is adapted with same matched locating piece.
Further, the locating piece is magnetic bar blocks.
The locating piece upper end is equipped with the upper locating convex block that is adapted with locating slot in supporting block, locating piece lower end be equipped with
The lower locating convex block that locating slot is adapted on cushion block.
One group of bicycle is equipped with below the longeron, each supporting mechanism is located at adjacent bicycle middle position.
The lower end of the supporting block is equipped with one group of bearing side by side, and cushion block is equipped with one group and the matched swivel base of bearing,
It is connected between one group of bearing and one group of swivel base by axis pin.
Compared with prior art, the present invention it has the following advantages：The trolley supporting mechanism is reasonable in design, supporting mechanism
It can pack up automatically when not in use, cushion block rotary is driven into rigid support by folding ram during use, it is easy to use,
It is reliable and stable.

In figure：
1. bicycle, 2. longerons, 3. crossbeams, 4. supporting mechanisms, 401. supporting blocks, 402. folding rams, 403. cushion blocks, 404.
Swivel base, 405. journal stirrups, 5. winding structures.
Specific embodiment
Below against attached drawing, by the description of the embodiment, making to the specific embodiment of the present invention further details of
Explanation.
As shown in Figure 1 to Figure 3, the trolley supporting mechanism including folding ram 402 and cushion block 403 and is located at mobile station
The supporting block 401 of vehicle longeron lower part, 402 upper end of folding ram are hinged with longeron lower part, 403 top of cushion block and supporting block lower end
It is hinged, the side of cushion block 403 and the lower end of folding ram are hinged.
2 lower section of longeron is equipped with one group of bicycle 1, and each rigid support mechanism 4 is located at adjacent bicycle middle position.Stress
Uniformly, carry reliable and stable.
Supporting block 401 is vertically arranged, and supporting block upper end is welded on the lower part of longeron 2.The width of supporting block and the width of longeron
Spend identical, the width of cushion block is more than the width of supporting block.Supporting ＆ stablizing is reliable.
The lower end of supporting block 401 is equipped with one group of bearing side by side, and cushion block is equipped with one group and the matched swivel base of bearing
404, it is connected between one group of bearing and one group of swivel base 404 by axis pin.Stable connection is reliable.The side of cushion block is equipped with journal stirrup 405,
The piston-rod lower end of folding ram is hinged by axis pin and journal stirrup.
Each by the hinge joint of axis pin in rigid support mechanism 4, rubber washer, hinge member and pin are equipped on axis pin
It is not directly contacted between axis equipped with rubber washer, axis pin is formed and is protected.
Bicycle includes vehicle frame and the jacking cylinder being located at central frame beam position.The upper end of jacking cylinder and longeron lower part phase
Even.Further, jacking cylinder is located at central frame beam position.Jacking cylinder includes the snap-gauge being located at the top of oil cylinder and is located at card
Rubber slab on plate, rubber slab, which can buffer, avoids motive objects from damaging.
The top of jacking cylinder is equipped with rotatable seat board on the outside of snap-gauge；Preferably, oil cylinder positioning, which is equipped with, opposite to turn
Dynamic rotor plate, rotor plate are connected by vertical oilless bearing with plane oilless bearing oil cylinder top, and seat board passes through fastener
It is located on rotor plate.
Seat board is rotatable with respect to oil cylinder, can coordinate mobile trolley used steering mechanism's cornering operation.It is mobile trolley used including longeron
2nd, crossbeam 3, rigid support mechanism 4, winding structure 5, steering mechanism and mobile bicycle 1 can voluntarily be driven.By jacking oil
When cylinder jacks up longeron, in vertical state, jacking cylinder does not work, and passes through rigid support machine for folding ram driving cushion block rotation
Structure support stringer, it is reliable and stable.
Supporting block and cushion block are being equipped with locating slot on pin roll end face side, on the locating slot and cushion block in supporting block
Locating slot is adapted with same matched locating piece.
Locating piece is magnetic bar blocks.Alternatively, locating piece upper end is equipped with the upper positioning being adapted with locating slot in supporting block
Convex block, locating piece lower end are equipped with the lower locating convex block being adapted with locating slot on cushion block.
When by jacking cylinder, longeron is jacked up, folding ram driving cushion block rotation passes through locating piece in vertical state
It is caught in the locating slot in supporting block and cushion block, prevents folding ram failure cushion block from rotating, supporting ＆ stablizing is reliable.Jacking cylinder is not
Work, passes through rigid support mechanism supports longeron.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements and from aforesaid way
Limitation, as long as employ the present invention design and technical solution carry out various unsubstantialities improvement or it is not improved will
The design and technical solution of the present invention directly applies to other occasions, within protection scope of the present invention.
