Technical field

The present invention relates to a kind of track construction car of laying railway roadbed for underground railway track traffic, particularly relate to a kind of running gear of track construction car.

Background technology

Underground railway track adopts non-fragment orbit mostly at present, by concreting solid bed.Due to railway roadbed curing period needs of just construct 48 hours, the running gear of track construction car is on the solid bed in curing period, to pass through, therefore prior art often utilizes door frame to hang oneself and be transported to the scope of operation and build from track construction car concrete hopper is housed, and the door frame speed of moving on interim door frame track is slow, handling once needs to take a long time, not only construction speed is slow, and has increased the weight of concrete workability, makes the solid bed quality of building unstable.

Summary of the invention

The object of the invention is to solve when the solid bed problem that track construction car cannot move during in curing period, and a kind of running gear of track construction car of convertible track is provided.

The object of the invention is to be achieved by the following technical programs:

A kind of running gear of track construction car, comprise a pair of inner beam of being located at hopper below, each inner beam bottom symmetric position arranges respectively interior rail road wheel, and this arranges respectively a principal arm to inner beam two ends, it is characterized in that each principal arm two ends is respectively equipped with the auxiliary with its bearing fit; One group of telescopic hydraulic cylinder is set, and each telescopic hydraulic cylinder connects with corresponding auxiliary, principal arm respectively; Each inner beam outside is respectively equipped with an outer beam, outer beam bottom symmetric position arranges respectively support, in support, be provided with outer rail road wheel, each support one side is equipped with drive motor, the axle drive shaft of drive motor and outer rail road wheel are connected, each outer beam connects with corresponding auxiliary, and each inner beam symmetric position arranges respectively lifting hydraulic cylinder, and the piston rod bottom of lifting hydraulic cylinder is connected with back-up block.

On the basis of technique scheme, can also there is following further technical scheme.

The auxiliary both sides at described each principal arm two ends are respectively equipped with one group of knock hole, and the both sides of each principal arm are respectively equipped with one group of through hole, and the two ends of each principal arm are equipped with movable latch, and movable latch is passed the through hole of principal arm, and coordinate with the knock hole formation location of auxiliary.

Described each principal arm two ends are respectively equipped with one group of guide holder, are provided with the cylinder with its normal-running fit in each guide holder, and cylinder periphery coordinates with auxiliary one side roll.

Under the effect of telescopic hydraulic cylinder and lifting hydraulic cylinder, by the mutual switching of inside and outside rail walking manner, track construction car not only can be moved on solid bed, also can on the interim door frame track of different gauges, move.

Beneficial effect of the present invention is simple in structure, and safe reliability is high, by the mutual switching of inside and outside rail walking manner, has improved track construction car construction speed, has guaranteed the solid bed quality of building.

Below just accompanying drawings and embodiment the present invention is further described.
