Magnetic pushing equipment for curved section reinforcement cage jacking and pushing device

Abstract

The invention relates to the technical field of prefabrication of immersed tubes, and discloses magnetic pushing equipment for a curved section reinforcement cage jacking and pushing device. The equipment comprises a sliding track, a base is movably installed on the sliding track, a first high-strength magnet is fixedly connected to the interior of the sliding track, a magnetic shielding assemblyis installed at the portion, located at the outer side of the first high-strength magnet, inside the sliding track and comprises two supporting rollers, a shielding section, a magnetism guide sectionand a stopping block, and a second high-strength magnet is fixedly connected to the bottom of the base. According to the magnetic pushing equipment for the curved section reinforcement cage jacking and pushing device, the high-strength magnets are installed on the base and the sliding track, the base is suspended through repulsive force generated by same magnetism between the magnets, and the jacking and pushing friction force is reduced accordingly; through the arrangement of the shielding section and the magnetism guide section on the magnetic shielding assembly, a magnetic field between thebase and the sliding track can be controlled, the base can be suspended only during jacking and pushing work, and thus the using convenience of the device is improved.

Description

technical field [0001] The invention relates to the technical field of immersed tube prefabrication, in particular to a magnetic pushing device for a steel cage pushing device in a curved section. Background technique [0002] The steel cage is a cage-shaped steel frame formed by binding steel bars together according to certain shape requirements. It mainly plays the role of accumulating fluid and improving strength. In the construction of underwater building tunnels, the immersed tube method is often used. Among them, the curved section pipe joints It is composed of multiple straight pipe joints, and the curved pipe joints need to be pushed to move the reinforcement cage after the binding and concrete pouring are completed. [0003] At present, the jacking of the steel cage is to use jacks and other equipment to push the steel cage along the sliding track. Because the steel cage itself is heavy in the curved section, it is difficult to push, and the friction between the sli...
