Pushing device of self-deviation-rectification guy rope hanging basket for bridge construction

Abstract

The invention relates to the technical field of bridge construction, in particular to a pushing device of a self-deviation-rectification guy rope hanging basket for bridge construction. The pushing device comprises a bottom die and a controller, and further comprises a walking mechanism and a deviation rectification mechanism, wherein the controller is arranged at one end of the top of the bottomdie, the walking mechanism is arranged on one side of the top of the bottom die, the walking mechanism comprises a C-shaped hook, a supporting assembly, a sliding assembly and an interlocking assembly, and the deviation rectification mechanism is arranged on the outer edge of the top of the bottom die and is located beside the walking mechanism. According to the pushing device, a first sliding rodand a second sliding rod are interlocked, a hydraulic jack drives a second sliding seat and the C-shaped hanging basket to move and drives the first sliding rod to move at the same time, at the moment, the second sliding rod is in a limiting state, when a second limiting groove in the first sliding rod slides to the same position of a clamping groove in a second sliding table, automatic locking is carried out, hydraulic oil is released, the first sliding seat drives the hydraulic jack and the second sliding rod to move at the same distance, the pushing device is simple to operate, safe and efficient, and accurate and controllable, and the sliding efficiency during construction of the guy rope hanging basket is greatly improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a driving device for a self-correcting guy cable hanging basket used in bridge construction. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountains, poor geology, or meet other traffic needs to make traffic more convenient. of buildings. Bridges are generally composed of superstructure, substructure, supports and auxiliary structures. The superstructure is also called bridge span structure, which is the main structure for crossing obstacles; The force transmission device installed at the support of the bottom formwork or abutment; the auxiliary structures refer to the bridge head board, conical slope protection, bank revetment, diversion w...

AI Technical Summary

Problems solved by technology

[0006] The structures of the above two inventions have the following disadvantages: in the first invention, a three-phase motor is used as a positive and negative motor, and the two sets of racks are driven by gear transmission to complete the lifting action synchronously, and the two sets of racks drive the thrust block to enter and exit the thrust In the keyway, the power of the motor is limited, and the front beam end of the hanging basket and the C-shaped hook have a large load. If it is used to drive the thrust block up and down and serve as the limit fulcrum of the hydraulic jack, it is easy to wear and tear the gear and rack. If it is damaged, it is not conducive to the disassembly and installation of the equipment; in the second invention, a hook is installed on the lanyard basket, and the self-weight of the lanyard basket is transferred to the concrete girder that has been poured, and the lifting device needs to be removed. There are two fulcrums of supporting beams, and one jack is required for every four finished rolled rebars

During the construction, the hanging baskets on both sides are lifted at the same time, and each hanging basket needs four jacks, and eight jacks need to be operated simultaneously, which requires too high cost and is not conducive to disassembly and installation
