Crane used for mounting of bridge prefabricated hanging boards and hoisting technology of crane

Abstract

The invention discloses a crane used for mounting of bridge prefabricated hanging boards and a hoisting technology of the crane. The crane comprises a base part, a counterweight part, a support part and a power part. The hoisting technology has the specific steps that the prefabricated hanging boards are conveyed to an operating area of the crane, all parts of the crane are detected, and all indexes are kept to be within the normal range; a winch is started, and the winch drives a hook on a steel wire rope to move; the prefabricated hanging boards are hung on the hook to be hoisted, and the prefabricated hanging boards are mounted on the designated positions; after one prefabricated hanging board is mounted, the crane is pushed to move forwards, the next the prefabricated hanging board ismounted continuously, continuous operation is conducted and so on; and after operation is finished, wheels of the crane are blocked by triangular wedges, and the mechanical failure accident due to land sliding of the crane is prevented. According to the crane and the hoisting technology, the bridge prefabricated hanging boards can be quickly, easily, rapidly and effectively mounted, the labor intensity of workers is small, and the working efficiency is high; personnel work on the bridge surface, operability is high, and the safety is high; and the mechanical effect per machine per shift is saved, diesel oil is not consumed, and environmental friendliness and energy conservation are achieved.

Description

technical field [0001] The invention relates to the field of installation of bridge prefabricated hanging panels, in particular to a crane for installing bridge prefabricated hanging panels and a hoisting process thereof. Background technique [0002] In highway engineering construction projects, the installation of prefabricated hanging panels on bridges is large, and truck cranes are required for installation. [0003] Disadvantages of the traditional installation process: [0004] The traditional hanging board installation process, the truck crane moves frequently, the working hours are long, and the efficiency is low; [0005] The installation of the hanging board belongs to high-altitude operations, and the truck crane can only work under the bridge, the coordination between the upper and lower command is poor, and the work efficiency of the workers is low; [0006] The traditional hanging board installation process needs to occupy one truck crane, which consumes one ...

Problems solved by technology

[0004] The traditional hanging board installation process, the truck crane moves frequently, the working hours are long, and the efficiency is low;

[0005] The installation of the hanging board belongs to high-altitude operations, and the truck crane can only work under the bridge, the coordination between the upper and lower command is poor, and the work efficiency of the workers is low;

[0006] The traditional hanging board installation process needs to occupy one truck crane, which consumes one shift of equipment and increases the installation cost;

[0007] Using truck cranes to consume diesel oil and pollute the environment
