Stepless height adjustment structure of straddle type track beam support

Abstract

A stepless height adjustment structure of a straddle type track beam support comprises a height adjustment stud and a height adjustment wrench for adjusting the height of the height adjustment stud, wherein a height adjustment stud mounting hole A is formed at the bottom of a lower seat plate; a lower seat plate height adjustment thread is arranged inside the height adjustment stud mounting hole A; a height adjustment stud mounting hole B corresponding to the height adjustment stud mounting hole A is formed at the upper part of a bottom plate; a bottom plate height adjustment thread is arranged inside the height adjustment stud mounting hole B; both ends of the height adjustment stud are provided with trapezoidal driving threads respectively matched with the lower seat plate height adjustment thread and the bottom plate height adjustment thread; and the trapezoidal driving threads at both ends of the height adjustment stud are oriented in opposite directions. The high-performance trapezoidal driving threads are used for driving the height adjustment structure so as to achieve the stepless height adjustment function of the straddle type track beam support.

Description

technical field [0001] The invention belongs to the technical field of bridge structures or construction, and relates to a stepless height-adjusting structure of a straddle-type track beam bearing. Background technique [0002] Straddle-type monorail traffic is a new form of modern urban high-speed rail three-dimensional traffic. It has low noise, strong climbing ability, small turning radius, fast and convenient, small footprint, low cost, no terrain restrictions, and environmental protection. Many advantages are a new trend in the future development of urban rail transit. [0003] The straddle-type monorail traffic track beam, as a two-way flexure member, not only bears the vertical load and horizontal load (centrifugal force, wind force, etc.) of the train, but also bears a large torsional load, and also acts as the track for the train. As an important part of the straddle-type monorail traffic track beam, the straddle-type track beam support is the key to ensure the nor...

Problems solved by technology

[0006] The height adjustment function of the existing PC track beam cast steel support is to adjust the height by filling the steel backing plate between the seat plate and the cam. There are disadvantages such as mutual misalignment, which is not conducive to the installation, construction and later maintenance of the support
