Straddle type single-rail track beam linear adjustment system and adjustment method

Abstract

The invention discloses a straddle type single-rail track beam linear adjustment system. The system comprises a straddle type monorail support seat and a three-dimensional adjustment device, wherein the three-dimensional adjustment device comprises a sliding seat I, a vertical adjustment mechanism, a horizontal adjustment mechanism and a longitudinal adjustment mechanism which are installed on a base, the base is arranged on the top of a cover beam, the sliding seat I is installed in the middle of the base in a sliding manner, a sliding pair I is arranged between the sliding seat I and the base, the vertical adjustment mechanism is arranged between a track beam and the sliding seat I, the horizontal adjustment mechanism is located between the two vertical hydraulic jacks, and the longitudinal adjustment mechanism is arranged on the base at the left and right sides of the sliding seat I. The movement of the hydraulic jacks of the vertical, horizontal and vertical adjustment mechanisms is controlled by oil pressure, so that the adjustment of the liner track beam is realized. The linear adjustment system has the advantages of being simple in structure, convenient to install and adjust, safe and reliable; the fine adjustment of the vertical, horizontal and longitudinal of the track beam is realized without the use of a beam erecting machine; and after the liner adjusting is finished, the support can be locked and positioned again by adjusting the horizontal and vertical adjustment mechanisms.

Description

technical field [0001] The invention relates to a track beam alignment adjustment device and an adjustment method, in particular to a straddle type monorail track beam alignment adjustment system and an adjustment method thereof. Background technique [0002] Straddle-type monorail traffic is a form of monorail traffic. Vehicles use rubber wheels to straddle the track beams that are integrated with beams and rails. In addition to running wheels, there are guide wheels and stabilizing wheels on both sides of the bogie. On both sides of the track beam to ensure that the vehicle runs safely and smoothly along the track. [0003] Straddle-type monorail transit is a medium-capacity urban rail transit mode, which is convenient and fast. Compared with the subway, it occupies less land, has low investment, and has low noise. It also has the advantages of strong adaptability, small turning radius, and strong climbing ability. [0004] In order to ensure the comfort of driving, the s...

Problems solved by technology

[0005] In addition, during the later operation of the track beam, the subsidence of the foundation, or the horizontal and vertical deformation of the track beam due to thermal expansion and contraction may occur, resulting in changes in the track beam line shape and affecting the safety of rail traffic; therefore, the track The beam also needs to be adjusted regularly in the later stage of operation

[0006] In the prior art, the linear adjustment of the track beam is mainly adjusted by the beam erecting machine and the permanent support, that is, after the track beam is hoisted and leveled, the linear height adjustment is realized by adding or reducing the gasket at the lower part of the permanent support. However, this method is firstly difficult to adjust, secondly, it cannot achieve small line adjustments, and thirdly, it needs to use a large beam erecting machine, which is time-consuming, laborious and costly
