An intelligent loading and unloading device for bridge pier formwork

Abstract

The invention discloses an intelligent loading and unloading device for a bridge pier formwork, which comprises a walking hoisting mechanism, a climbing mechanism and a sensor mechanism. The walking mechanism adopts a crawler chassis to provide movement for the device. The hoisting mechanism realizes the transportation and installation of the steel formwork through the hydraulic rod. The climbing mechanism uses the driving motor as the power, and the upper gear rail of the steel formwork is used as the track to realize the climbing of the device. The device is equipped with laser radar, binocular camera and microcomputer. Relying on the laser radar, binocular camera and steel template BIM model, the microcomputer automatically controls the drive motor and hydraulic rod to realize the device's transportation, climbing and mechanical arm movement. The hook is mounted on the gear groove through the cantilever to assist the cross bar to carry the steel formwork. With the assistance of lidar and binocular cameras, the microcomputer controls the driving motor to lift the upper steel formwork to the installation level, and then controls the hydraulic rod to lower the formwork to be installed to achieve precise docking with the installed formwork and record the installation information in real time. The construction is completed Finally, the microcomputer realizes the automatic disassembly of the pier steel formwork according to the installation records.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a Intelligent loading and unloading device for pier formwork technology. Background technique [0002] High-speed railway occupies a pivotal position in the development of the national economy. It has the characteristics of good safety, high speed, large transportation volume, low comprehensive transportation cost and low environmental pollution. In order to ensure the safety and stability of train running, effectively avoid the subsidence and deformation of the foundation of the railway in poor geological areas, and at the same time reduce the damage to the ecological environment and the occupation of cultivated land, the construction of high-speed railways often adopts "replacing roads with bridges" and replacing them with bridges. The traditional roadbed is used as the carrier of the high-speed rail track. [0003] At present, the pier construction of high-speed ...

Problems solved by technology

[0005] Technical problem: In order to solve the problems in the installation and construction of the bridge pier formwork that the lifting of the steel formwork can easily threaten the personal safety of the construction personnel, the adjacent steel formwork is prone to collision, the installation and positioning of the formwork is difficult, and the construction efficiency is low. A bridge pier formwork intelligent loading and unloading was invented. The device, assisted by laser radar, binocular camera and microcomputer, based on the BIM model of the steel formwork, uses the walking crawler and drive motor to automatically carry, lift and disassemble the steel formwork, and uses the hydraulic rod to drive the steel formwork for precise alignment. At the same time, the device supports Multiple construction work surfaces can effectively ensure the safety and accuracy of pier steel formwork handling, installation, and disassembly operations, and have the advantages of convenient and efficient implementation
