An efficient rapid lifting device for road and bridge construction tools

Abstract

The invention discloses a high-efficiency rapid lifting device for road and bridge construction tools, which comprises a base and a gantry frame, the gantry frame is fixed on the base, the opposite side walls of the gantry frame are provided with limiting slots, and the two A tool box is slidably connected in the limit slot, and a take-up roller is installed between the gantry frames, and the gantry frame is provided with two opposite installation grooves located above the take-up rollers, and between the two installation grooves A mounting rod that can move up and down is installed, a fixed pulley is installed on the mounting rod, a transmission mechanism is provided between the driving motor and the take-up roller, and a chute is provided on the opposite side of the gantry, two The opposite side of the chute is provided with pull plates. The invention has a reasonable structure, realizes the rapid lifting of the tool box, and also has the function of preventing falling, and can also protect the staff under the condition of protecting the tool, and can perform a stable limit on it to ensure its stability during work .

Description

technical field [0001] The invention relates to the technical field of bridge construction equipment, in particular to an efficient rapid lifting device for road and bridge construction tools. Background technique [0002] Road bridges are generally composed of several parts such as roadbed, road surface, bridge, tunnel engineering and traffic engineering facilities. Roadbed engineering: Roadbed is a linear structure built with soil or stone. Pavement engineering: Pavement is a layered structure that is layered on the roadbed with various road-building materials or mixtures for vehicles to drive. Bridge and tunnel engineering: Bridge and tunnel engineering is an important part of high-grade highways. Highway: Highway tunnel engineering is a wise choice for mountainous highways, and the lifting device is a mechanical conveying device for a fixed device. [0003] In the construction of roads and bridges, it is usually necessary to lift the construction tools to a high place...

AI Technical Summary

Problems solved by technology

[0003] In the construction of roads and bridges, it is usually necessary to lift the construction tools to a high place for high-altitude construction. However, the current common method of lifting the tools to a high place is mainly to pull the tools up by manpower, which is time-consuming and labor-intensive. , and it is very unsafe. The tool is easy to fall due to the loose hands of the staff during the ascent process, which affects work efficiency, and the tool is easy to shake when it is raised, which will increase the tension of the rope, and there is a certain danger.
