Hydraulic pipe drawing device

Abstract

The invention provides a hydraulic pipe drawing device, relating to the field of building construction. The hydraulic pipe drawing device consists of a hydraulic system and a pipe drawing device; the hydraulic ram arm of the hydraulic system is provided with a pipe drawing frame; the middle part of the pipe drawing frame is provided with a large steel pipe insertion hole; the insertion hole and the large steel pipe are locked firmly by a locking device. The hydraulic pipe drawing device of the invention is corollary equipment of the construction method for the impact-typed large-diameter steel pipe pore-forming pouring pipe. The hydraulic pipe drawing device has simple structure, large upper drawing force and convenient movement; especially the steel pipe is clamped firmly by tapered iron; therefore, the hydraulic pipe drawing device has the greatest advantages that the greater the upper drawing resistance of the steel pipe is, the greater the claming force is, thus leading the steel pipe punched into the ground with extremely large upper drawing resistance to be pulled out easily.

Description

1. Technical field: [0001] The invention relates to the field of building construction, in particular to building construction equipment. 2. Background technology: [0002] At present, the construction cast-in-place piles are mainly artificial hole-digging cast-in-place piles and mechanical hole-forming mud retaining wall cast-in-place piles. There are many deficiencies in these two methods, so the inventor designs a kind of cast-in-situ pile construction utilizing large-diameter steel pipes to form holes. method, but the large-diameter steel pipe needs to be lifted and pulled when pouring concrete, and the current equipment cannot realize the lifting and pulling of the steel pipe with a large height and large diameter to realize the reuse of the steel pipe, so the large-scale production of this advanced construction method influence. 3. Contents of the invention: [0003] The object of the present invention is to overcome the above disadvantages and provide a hydraulic e...

[0002] At present, the construction cast-in-place piles are mainly artificial hole-digging cast-in-place piles and mechanical hole-forming mud wall-protecting cast-in-place piles. There are many deficiencies in these two methods. Therefore, the inventor designs a kind of cast-in-place pile that utilizes large-diameter steel pipes to form holes. method, but large-diameter steel pipes need to be lifted and pulled when pouring concrete, and the current equipment cannot realize the lifting and pulling of steel pipes with large heights and large diameters to realize the reuse of steel pipes, so the large-scale production of this advanced construction method influence
