Constructional engineering concrete pipe pile pulling-out device

Abstract

The invention provides a constructional engineering concrete pipe pile pulling-out device. The constructional engineering concrete pipe pile pulling-out device comprises a lifting cylinder, an upper sliding table, a translation frame, a first driving piece, a chain, a driven chain wheel, a second driving piece, a lifting driving wheel set and a third driving piece; the upper end and the lower endin the middle of the lifting cylinder are rotationally connected with pile pulling-out columns through bearings; supporting legs are fixedly connected to the lower portion of the upper sliding table in a welded mode; the first driving piece is fixedly connected to the upper surface of the upper sliding table through a bolt; the driven chain wheel is rotationally connected to the right side of theupper surface of the upper sliding table through a bearing; the chain is meshed with the driven chain wheel and a chain wheel at the output end of the first driving piece; the translation frame is movably connected to the upper sliding table and is fixedly connected to the chain; and the second driving piece is fixedly connected to the upper end of the lifting cylinder. It can be seen that compared with existing manual handheld operation or hoisting equipment operation, the pile pulling-out device has higher accuracy, manpower resource waste caused by manual supporting is reduced, and the construction efficiency and the construction quality are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of pipe pile digging equipment, and more specifically relates to a construction engineering concrete pipe pile digging device. Background technique [0002] At the end of the 1960s, the Fengtai Bridge Factory of the Ministry of Railways began to produce pre-tensioned prestressed concrete pipe piles (referred to as PC piles), which were mainly used for the foundation construction of railway bridge projects; in the 1970s, post-tensioned prestressed concrete pipes were developed and produced. piles, with the development of reform and opening up and economic construction, pretensioned prestressed concrete pipe piles began to be widely used in railway systems, and expanded to industrial and civil buildings, municipal, metallurgy, ports, highways and other fields, with the development of cities , More and more construction sites are being developed. Concrete pipe piles are very important in infrastructure construc...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a construction engineering concrete pipe pile excavation device to solve the problem of cleaning the silt in the pile hole before filling the pile core when using the concrete pipe pile similar to the above-mentioned patent. The cleaning method is to manually hold or hang the dredging equipment to clean the silt in the pile hole, which wastes human resources and lower construction efficiency.
