Multifunctional installation equipment for steel pipe column

Abstract

The invention discloses multifunctional installation equipment for a steel pipe column. The equipment comprises a chassis component, a loading component, a braking component, a braking fixed shaft, a front luffing link, a rear luffing link, a luffing oil cylinder, a suspension arm component, a main winching assembly, an auxiliary winching assembly, a front support leg component, a rear support leg component, a front support wall lead screw and a rear support wall lead screw. According to the equipment disclosed by the invention, the angle change of the installed steel pipe column is displayed by virtue of a high-accuracy tilt angle sensor, a worker has no need to go down into a hole to install and locate by virtue of the equipment, and therefore, two phases of installing a steel casing and detaching the steel casing can be omitted. The equipment adjusts the verticality of the steel pipe column through adjusting the own angle after the whole steel pipe column is installed, without the need of the basis of a novel PBA construction method. The multifunctional installation equipment for the steel pipe column, which is capable of replacing manual operation and high in accuracy, is capable of reducing the labour intensity of workers and reducing the safety risk of construction.

Description

technical field [0001] The invention relates to a steel pipe column installation device, in particular to a steel pipe column installation device with multiple functions applicable to ground or tunnels. Background technique [0002] With the continuous increase of traffic density in some large and medium-sized cities in my country, the role of subway as a major urban transportation tool has become increasingly prominent. China's urban transportation has entered the subway era. Compared with the increasing demand for subways in large and medium-sized cities, the development of subway construction technology is slow, especially in the degree of mechanization of subway construction. At present, the excavation of subway stations mainly adopts the PBA construction method, which is divided into traditional PBA construction method and new PBA construction method. The traditional PBA construction method is the reverse construction method of the underground frame structure and the u...

AI Technical Summary

Problems solved by technology

The traditional PBA construction method is 8 pilot holes and 6 pilot holes. Manually digging holes and manually positioning steel pipe columns has poor positioning accuracy, high labor intensity and long construction period.

The new PBA construction method is 4 pilot holes, which are drilled with mechanical equipment. However, the positioning and installation of the steel pipe column still adopts the method of manual drilling. This method needs to be lowered into the steel casing. Therefore, the construction period is longer, the cost is higher, the risk of worker safety is greater, and the positioning accuracy of the steel pipe column is lower
