Problems solved by technology

In the above-mentioned construction, the walking-type automatic jacking equipment is expensive, the construction speed is slow, and the construction period is long; the steel structure flat slideway has a heavy structure, high friction resistance, and the construction speed is slow; the roller trolley slideway has small structures and heavy weight. Lightweight, low frictional resistance, fast construction speed, short cycle, etc. However, in the push / drag construction, the direction deviation is easy to occur due to the high speed, and when the deviation is large, it is necessary to stop the construction to adjust and correct the deviation, and correct the deviation in the static state Prolonged construction time and increased costs such as manpower and material resources

Abstract

The invention discloses a rolling wheel trolley device integrating the traveling function with the limiting adjusting function. The device comprises a sliding device and a limiting adjusting device arranged on the side face of the sliding device. The sliding device comprises a pulley (2), a bearing beam (3) arranged on the lower portion of the pulley (2) and fixedly connected with the pulley (2), and a carrying frame (4) arranged on the lower portion of the bearing beam (3). A horizontal adjusting mechanism (14) is arranged between the carrying frame (4) and the bearing beam (3). The bearing beam (3) pitches and swings through the horizontal adjusting mechanism (14), and continuous track type rolling wheels (1) are arranged on the upper portion of the pulley (2). The limiting adjusting device comprises a jack (9) used for transverse adjustment, a movable jack force transmission base (8) and a limiting adjusting rolling wheel (6) arranged at the front end of the movable jack force transmission base (8), and the jack (9) and the limiting adjusting rolling wheel (6) are in transmission connection through the movable jack force transmission base (8).

Description

technical field [0001] The invention relates to a roller trolley device integrating the functions of running and limit adjustment, and is a mechanical device for pushing or dragging structures to target positions. The invention also discloses a method for pushing / dragging a structure by using the roller trolley device. Background technique [0002] With the development of my country's railways, highways, and municipal engineering construction, there are more and more bridge structures across railways, highways, and rivers, and the use of push / drag construction of bridge structures is becoming more and more common. Comprehensively considering that the slides used in the push / drag construction are mostly walking automatic push equipment, steel structure flat slides and roller trolley slides. In the above-mentioned construction, the walking-type automatic jacking equipment is expensive, the construction speed is slow, and the construction period is long; the steel structure fl...
