Abstract

The invention belongs to the technical field of bridge landing equipment and discloses a self-locking-type multidirectional deviation-rectifying hydraulic device for safe bridge landing and a use method of the device. According to the main technical features, the self-locking-type multidirectional deviation-rectifying hydraulic device comprises a box body which is provided with a rectangular sliding frame and a self-locking-type jack; and a push-pull oil cylinder fixing seat where a push-pull oil cylinder is fixed is arranged at the rear end of the rectangular sliding frame, and the push-pulloil cylinder is connected with the jack. An upper sliding plate is arranged on the bottom face of the jack, and a lower sliding plate is arranged at the bottom of the box body. A left deviation-rectifying oil cylinder fixing seat where a left deviation-rectifying oil cylinder is fixed is arranged on the left side of the box body, and a right deviation-rectifying oil cylinder fixing seat where a right deviation-rectifying oil cylinder is fixed is arranged on the right side of the box body. The push-pull oil cylinder, the left deviation-rectifying oil cylinder and the right deviation-rectifyingoil cylinder are connected with a hydraulic control system. According to the self-locking-type multidirectional deviation-rectifying hydraulic device for safe bridge landing, through adjusting in sixdirections, accurate control over bridge landing is achieved, the structure is simple, the occupied operation space is small, and jacking, lowering, pushing and pullback are stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of bridge beam drop equipment, and in particular relates to a self-locking multi-directional deviation correcting hydraulic device for safe beam drop and a use method thereof. Background technique [0002] There are various construction techniques for bridges, but in the construction process of over-span bridges, especially highways, high-speed railways, municipal roads with heavy traffic and waters with high navigation requirements, or due to problems such as limited construction sites, it is necessary to The beam body is prefabricated before the beam is erected. In the process of erecting the beam, due to problems such as construction technology, construction environment and construction site, the beam needs to be dropped to the design position in a specific position and in a specific environment, so that the bridge erecting machine cannot be used. Contents of the invention [0003] The first technical ...
