Rapid tool lifting equipment for civil engineering road and bridge construction

Abstract

The invention discloses rapid tool lifting equipment for civil engineering road and bridge construction, which structurally comprises a base, an auxiliary lifting device, a lifting extension rod, an extension control device, a lifting joint, a pull rope, a generator, a take-up and pay-off box and a lifting upright post. The invention has the following beneficial effects: By arranging a front-backmoving device directly controlled by a chain and an auxiliary rod connected with a protective connecting rod with double lantern rings and forming a triangular reinforcing frame with the upright post,the lifting extension rod of the equipment can be conveniently moved and adjusted front and back through a lifting chain, and the lifting extension rod is provided with a movable auxiliary anti-toppling connecting rod; the equipment better ensures the safety of use of the equipment when conveniently adjusting the length of the extension rod. The base is provided with a top plate convenient to slide, and supporting foot rods and moving wheels which are capable of being switched by the top plate, so that the equipment can perform convenient switching of the top plate for the moving wheels and the supporting foot rods by means of pushing a switching connecting plate assembled on the top plate. The switching is labor-saving, quick and convenient.

Description

technical field [0001] The invention belongs to the technical field of tool rapid lifting equipment, in particular to a tool rapid lifting equipment for civil engineering road and bridge construction. Background technique [0002] When carrying out high-altitude construction, due to the influence of the high-altitude environment, etc., it is inconvenient for the construction personnel to carry and take the tools required during construction. At this time, it is necessary to be able to lift the tools and pass them on to the construction personnel. , during the construction of roads and bridges, construction workers sometimes need to carry out engineering work on the bottom of the bridge. Because of the bridge itself and geographical factors, the tools are generally lifted from the upper side, and these tools are conveniently and quickly lifted and transferred. For tools to quickly upgrade equipment, with the rapid development of science and technology, technical improvements ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the deficiencies of the existing technology, a quick lifting equipment for civil engineering road and bridge construction tools is proposed to solve the problem of using the new type of the existing technology. The telescopic extension rod has poor stability and is prone to the danger of overturning, while the fixed extension rod is inconvenient for the distance requirements of different places, and when the existing technology is used, it is difficult to move and When the fixed support is switched, it is necessary to lift the equipment or support the switch, and the force required for the switch is relatively large, resulting in inconvenient use
