Abstract

The invention discloses a support for a track beam and a track. The support comprises: a lower support plate; an upper support plate, wherein the upper support plate is arranged above the lower support plate, and the upper support plate is suitable for being fixedly connected with the track beam; and a support body, wherein the support body is fixed between the upper support plate and the lower support plate. The upper support plate comprises an upper surface and a lower surface which are arranged in a spaced mode, the lower surface is suitable for being horizontally arranged, a first preset angle is formed between the upper surface and the lower surface in the longitudinal bridge direction, a second preset angle is formed between the upper surface and the lower surface in the transverse bridge direction, the first preset angle is equal to the longitudinal slope gradient of the track beam at the fixed position of the support, and the second preset angle is equal to the cross slope gradient of the track beam at the fixed position of the support. The support is simple in structure, the gradient of the track beam can be accurately met, and construction is easy.

Description

technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to a support and a rail for rail beams. Background technique [0002] In the track, the linear accuracy of the track beam directly affects the driving safety of the rail vehicle. In related technologies, the linear accuracy of the curved track beam is difficult to guarantee, and there are problems such as installation and fixation of the support. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a support for track beams, which has a simple structure, can accurately meet the slope of track beams, and is easy to construct. [0004] The invention further proposes a track. [0005] A bearing for a track beam according to the present invention, comprising: [0006] lower support plate, [0007] An upper support plate, the upper suppor...
