Abstract

The invention belongs to the technical field of bridge erection construction, and discloses an efficient pushing system device which comprises a hydraulic clamp holder, a horizontal pushing hydraulic cylinder, a second connecting pin shaft, a heavy-load roller trolley, a three-dimensional fine adjustment assembly and a servo hydraulic system. The hydraulic clamp holder, the horizontal pushing hydraulic cylinder, the heavy-load roller trolley and the three-dimensional fine adjustment assembly are connected with the servo hydraulic system through hydraulic oil ways; the horizontal pushing hydraulic cylinder and the heavy-load roller trolley are connected into a whole by the hydraulic clamp holder through the second connecting pin shaft; and the three-dimensional fine adjustment assembly is placed on the upper plane of the heavy-load roller trolley. The number of distribution points of the heavy-load roller trolley is reduced, the direction is rapidly and accurately adjusted through the three-dimensional fine adjustment assembly, traffic under the bridge is not affected during incremental launching construction, large hoisting equipment is not needed, aerial work is not needed, and the device is particularly suitable for construction of urban extra-large-span bridges, long-line approach bridges or flyover crossing and river crossing.

Description

technical field [0001] The invention belongs to the technical field of bridge erection construction, and in particular relates to a high-efficiency jacking system device. Background technique [0002] Now when the whole bridge moves along the specified direction, the rear fixed point adopts the way of pin shaft to the hole to fix and push the hydraulic pressure cylinder. Every time the stroke of the hydraulic cylinder is in place, it needs to be operated repeatedly to correspond to the hydraulic valve and the track installation hole, which takes too long and greatly damages the In addition, the bearing capacity of the push-sliding trolley is small, and multiple load-carrying trolleys are required to arrange points, and the construction error is too large; the horizontal height and branch line degree of the overall bridge relative to the design value need to be adjusted by independent hydraulic cylinders, and its control The difficulty is high, and the adjustment accuracy err...
