Column pulling device for water conservancy project

Abstract

The invention relates to a column pulling device for a water conservancy project. The inclined upper end of an inclined connecting rod is fixedly connected with the inner side wall of a supporting rotating shaft; the supporting rotating shaft is fixedly arranged on a fixing supporting frame; four moving grooves are formed in the upper end face of a connecting sleeving ring; a first moving plate and a second moving plate are movably arranged in the moving grooves; the first moving plate and the second moving plate are connected through a plurality of first supporting springs; a mud scraper is fixedly connected with the end, away from the first moving plate, of the second moving plate; the sides, close to each other, of the mud scraper and a column body are arranged in a sliding mode; and alocking mechanism is arranged inside mud scraping equipment and used for locking the relative positions of the first moving plate and the second moving plate. According to the column pulling device for the water conservancy project, the arrangement of a clamping jaw can be suitable for clamping and pulling of column piles made of different materials, so that the problem that the clamping jaw and the column piles slide relative to each other in the column pile pulling process is avoided, and therefore the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a column pulling device for water conservancy engineering. Background technique [0002] Projects built to eliminate water damage and develop and utilize water resources. According to its service objects, it is divided into flood control projects, farmland water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and tidal flat reclamation projects. Water conservancy projects that can simultaneously serve multiple purposes such as flood control, water supply, irrigation, and power generation are called comprehensive utilization water conservancy projects. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, canals, rafts, and fishways to achieve their goals. Compared wi...

Problems solved by technology

②Water conservancy projects are generally large in scale, require large investment, complex technology and long construction period

[0004] However, due to the different materials of the column piles, when the same jaw is used to extract the column piles, there is a problem that the column cannot be clamped. Due to the residual muddy water on the surface of the steel column during the extraction process of the steel column, the surface of the steel column It is slippery, so when using the jaws to clamp the steel column, there is a problem that it cannot be clamped. At the same time, the existing column piles have the problem of time-consuming and laborious during the extraction process. Moreover, the existing column piles are in the After extraction, the surface needs to be manually cleaned for subsequent use. Due to manual cleaning, not only is there a problem of time-consuming and labor-intensive, but also there is a problem of low efficiency
