Abstract

The invention discloses a fixing pile pulling-out device. The fixing pile pulling-out device comprises a support capable of adjusting the pile pulling direction and a pile pulling mechanism connected to the support. The pile pulling mechanism can reciprocate in the height direction of the support and is connected with a fixing pile, and the pile pulling mechanism is controlled to move upwards to pull out the fixing pile. Consumption of manpower and material resources is lowered, potential safety hazards in the pile pulling process are eliminated, the side face of a pile body of the fixing pile does not need to be knocked in the pile pulling process, and therefore the pile body is prevented from being damaged, and the service life of the fixing pile is guaranteed. The invention further discloses the fixing pile capable of being pulled out through the fixing pile pulling-out device. The fixing pile comprises the pile body which can be pulled out through a pile pulling steel cap connected between the pile pulling mechanism and the pile body of the fixing pile pulling-out device. During pile pulling, the steel cap and the pile body are connected into a whole, the fixing pile pulling-out device is connected with the steel cap, and the reliability of connection with the fixing pile pulling-out device is enhanced.

Description

technical field

[0001] The invention relates to a device for pulling out a pile and a fixed pile, in particular to a device for pulling out a pile and a fixed pile. Background technique

[0002] When carrying out construction operations such as transporting, lifting, and poles in the wilderness, since large-scale machinery cannot enter the site, it can only be completed by small-scale machinery and human hands. In the process of completing tasks, temporary fixing piles are often used. And fixed pile is widely used owing to having simple, practical and low cost advantage, but the biggest shortcoming of fixed pile is: it is easier to drive in and difficult to pull out. The pile pulling process requires a lot of manpower and material resources and also takes a lot of time, and the pile pulling method is very unsafe and has potential safety hazards, while the traditional pile pulling requires knocking on the side of the pile, which often leads to damage and deformation of the fi...
