Abstract

The invention discloses a steel truss girder walking-type pushing device. The steel truss girder walking-type pushing device comprises a sliding rail and multiple groups of pushing device bodies, a hydraulic pump station and a PLC main controller which are arranged on the sliding rail; the sliding rail comprises a bottom plate and a sliding plate, the two edges of the bottom plate are provided with multiple rectangular clamping grooves which are uniformly distributed, the pushing device comprises a sliding box, a jacking oil cylinder, a flat pushing oil cylinder and a rectifying oil cylinder, the sliding box can slide on the sliding track, a piston of the flat-pushing oil cylinder is connected with one end of the sliding box through a flat-pushing hinge pin, pawls distributed on the two sides of a cylinder body are connected to the bottom of the cylinder body of the flat-pushing oil cylinder through connecting hinge pins, teeth matched with the rectangular clamping grooves are arranged on the portions close to the front ends of the pawls, one side plate of the sliding box is connected with a cylinder body of the rectifying oil cylinder, a piston of the rectifying oil cylinder faces the interior of the sliding box, and the head of the piston is provided with a rectifying lug plate. The steel truss girder walking-type pushing device is simple in structure, and manpower and material resources are saved; construction is conducted through hydraulic jacking, and impulse inertia does not exist.

Description

technical field [0001] The invention is located in the field of bridge construction equipment, and in particular relates to a steel truss girder walking type pushing device. Background technique [0002] In the installation and construction of steel truss girders, due to the limitation of the force of truss girder chord joints, the traditional pull method has always been used for construction. , horizontal jacks, etc. After the sections in the assembly section are assembled, the horizontal jacks will be used to apply force, and the steel truss girder will be pushed forward with the help of slideways and sliders, and the beam will be dropped after being pushed to the predetermined position to complete the installation of the steel truss girder. . However, this method needs to arrange a large number of slideways on the pier to meet the stress problem of the steel truss girder, resulting in the need to do a lot of preparation work in the construction, the efficiency is low, an...
