Column pulling device for water conservancy projects

Abstract

The invention relates to a column pulling device for water conservancy projects. The inclined upper end of an inclined connecting rod is fixedly connected to the inner side wall of a supporting rotating shaft, and the supporting rotating shaft is fixedly arranged on a fixed supporting frame. Four connecting rings are provided on the upper end surface. No. 1 moving plate and No. 2 moving plate are movable in the moving slot. The No. 1 moving plate and No. 2 moving plate are connected by several No. 1 support springs, and the No. 2 moving plate is far away from the One end is fixedly connected with a scraper, and the side where the scraper and the cylinder are close to each other is slidingly set; a locking mechanism is provided in the mud scraping device, and the setting of the locking mechanism is used to lock the relative position of the No. 1 moving plate and the No. 2 moving plate. Location. The arrangement of the present invention is applicable to the clamping and pulling of piles of different materials, and avoids the problem of mutual sliding between the clamping jaws and the piles during the pulling of the piles, thus improving the efficiency of construction.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a column pulling device for hydraulic engineering. Background technique [0002] Projects built to eliminate water hazards and develop and utilize water resources. According to its service objects, it is divided into flood control engineering, farmland water conservancy engineering, hydroelectric power generation engineering, waterway and port engineering, water supply and drainage engineering, environmental water conservancy engineering, sea flat reclamation engineering, etc. A water conservancy project that can serve various goals such as flood control, water supply, irrigation, and power generation at the same time is called a comprehensive utilization water conservancy project. Water conservancy projects require the construction of different types of hydraulic structures such as dams, embankments, spillways, sluice gates, water inlets, channels, ferries, rafts,...

AI Technical Summary

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
