Bridge linetype multi-dimensional adjusting device

Abstract

The invention discloses a bridge linetype multi-dimensional adjusting device. The device is arranged below a bridge beam body and comprises a position locking mechanism, an inclination adjusting mechanism, a transverse leveling adjusting mechanism and a height adjusting mechanism; the position locking mechanism is provided with an inclination-prevention framework which covers the outer side of thebridge beam body, and the inclination adjusting mechanism comprises an upper swinging device, a lower swinging device arranged above the upper swinging device, cross slope ultrahigh actuating cylinders and inclination adjusting and locking bolts, and the inclination adjusting and locking bolts adjust and then fix the upper swinging device and the lower swinging device; the transverse leveling adjusting mechanism comprises a base plate which is used for placing the lower swinging device and fixedly arranged at the portion where the lower swinging device is located and horizontal actuating cylinders, the horizontal actuating cylinders are arranged at the two transverse sides of the lower swinging device and push the lower swinging device to move left and right in the transverse direction, and the height adjusting mechanism is arranged below the lower swinging device and pushes the lower swinging device to move up and down in the vertical direction. According to the device, convenience is brought to linetype adjustment of the bridge beam body, in particular to bridge line erection and linetype adjustment of straddle-type monorail transportation track beams and other beams which havestrict requirements for the bridge linetype.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a bridge alignment multi-dimensional adjustment device. Background technique [0002] Bridge alignment adjustment is an important process in bridge erection construction. The quality of bridge alignment directly affects the safety of bridge structures and the comfort of operating vehicles. Especially for track beams that are used as vehicle running tracks, the adjustment of bridge alignment is even more important. [0003] Straddle-type monorail traffic is a new form of modern urban rapid rail three-dimensional traffic, with low noise, strong climbing ability, small turning radius, fast and convenient, less land occupation, low cost, not restricted by terrain, and conducive to environmental protection, etc. Many advantages are a new trend in the development of urban rail transit in the future. [0004] As a two-way flexural member, the straddle-type monorail traffic track beam n...
