CN202764998U - Track construction vehicle chassis - Google Patents

Abstract

The utility model relates to a track construction vehicle, in particular to a track construction vehicle chassis. The track construction vehicle chassis comprises a sleeper beam, a left side beam and a right side beam, wherein the left side beam and the right beam are arranged on two ends of the sleeper beam. A lower plane of the sleeper beam is parallel and level to the lower plane of the left beam and the lower plane of the right beam. The upper plane of the left beam and the upper plane the right beam is higher than the upper plane of the sleeper beam. On the basis of ensuring the strength of the chassis, the track construction vehicle chassis has the advantage of enabling an engineering vehicle bogie to pass a small radius curve section without any obstacle. Further, the track construction vehicle chassis enables users to arrange lower pipelines below the chassis conveniently.

Description

A kind of track engineering under-carriage

Technical field

The utility model relates to the railway traffic engineering car, is specially the track engineering under-carriage.

Background technology

In existing railway traffic engineering under-carriage structure, general curb girder lower plane height to the top of rail is less than sleeper beam lower plane height to the top of rail, and the plane is concordant with plane on the sleeper beam on the curb girder; In sleeper beam, need simultaneously other perforate with the mistake pipeline, but be subjected to the less layout that is not easy to pipeline of dimensional restriction institute hole-opening.Bogie truck is with after underframe connects, the top of truck frame on underframe curb girder lower plane, when engineering truck during through sharp radius curve bogie truck and underframe curb girder may bump.

Summary of the invention

The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of track engineering under-carriage, realizes that the engineering truck bogie truck is without barrier by the sharp radius curve highway section.

The technical solution of the utility model is, a kind of track engineering under-carriage comprises the left and right curb girder at sleeper beam and sleeper beam two ends, and the lower plane of described sleeper beam is concordant with the lower plane of left and right curb girder, and the upper plane of left and right curb girder is higher than plane on the sleeper beam.

When the engineering truck bogie truck with after underframe connects, because truck frame all is under the left and right curb girder lower plane, bogie truck and left and right curb girder collision in the time of can avoiding engineering truck to cross sharp radius curve makes things convenient for engineering truck accessible by the sharp radius curve highway section; The gap between plane and the underframe top board makes things convenient for underframe stringing and wiring on the sleeper beam simultaneously, and needn't be limited by the less limitation of institute's hole-opening size in the sleeper beam.

As known from the above, the utility model realizes on the basis that guarantees underframe intensity that as a kind of track engineering under-carriage the engineering truck bogie truck without barrier by the sharp radius curve highway section, makes things convenient for the layout of underframe underground pipelines simultaneously.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of track engineering under-carriage comprises the left and right curb girder 1,2 at sleeper beam 3 and sleeper beam two ends, and the lower plane of sleeper beam 3 and left and right curb girder 1,2 lower plane are concordant, and left and right curb girder 1,2 upper plane are higher than plane on the sleeper beam 3.

Claims (1)

1. track engineering under-carriage comprises the left and right curb girder (1,2) at sleeper beam (3) and sleeper beam two ends, it is characterized in that, the lower plane of the lower plane of described sleeper beam (3) and left and right curb girder (1,2) is concordant, and the upper plane of left and right curb girder (1,2) is higher than the upper plane of sleeper beam (3).
