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
One, technical field:
The present invention relates to the realm of building construction, particularly construction implement.
Two, background technology:
Be mainly manually digging hole filling pile and mechanical hole building slurry drilled pile in the building castinplace pile at present, these two kinds of methods exist the not enough problem of all many-sides, therefore the inventor designs a kind of cast-in-place pile construction method that utilizes the large diameter steel pipe pore-forming, but large diameter steel pipe need promote tube drawing when pour concrete, steel pipe highly big, that diameter is big promotes tube drawing and present equipment can't be realized, to realize the recycling of steel pipe, therefore the large-scale productionization of advanced job practices is brought influence for this reason.
Three, summary of the invention:
The objective of the invention is to overcome above-mentioned not enough problem, a kind of hydraulic pipe drawing device is provided, simple in structure, uplift force is big, the efficient height.
The technical scheme that the present invention is adopted for achieving the above object is: hydraulic pipe drawing device, form by hydraulic system, pipe extractor, on the hydraulic jack arm of hydraulic system the tube drawing frame is housed, has the big steel pipe jack in the middle of the tube drawing frame, lock by locking device between jack and the big steel pipe.
Described locking device is a wedge.
Described tube drawing frame has pilot hole, and pilot hole is sleeved on the oil cylinder arm.
Described Hydraulic Station is supplied with the hydraulic oil of 30mpa.By distributor fuel feeding about the pipe extractor oil cylinder.
Apparatus of the present invention are the corollary equipment of drive type major diameter steel pipe pore-creating filling pile job practices, and are simple in structure, and uplift force is big, conveniently moving.Hydraulic Station is supplied with the hydraulic oil of 30mpa, by distributor fuel feeding about the pipe extractor oil cylinder, to realize moving up and down of oil cylinder.Drive the tube drawing frame when oil cylinder moves up and move up, the wedge of tube drawing frame clamps steel pipe and drives steel pipe and moves up together when mobile.When oil cylinder moves to stroke terminal, oil cylinder is descending, and clamp wedge this moment loosens, and the tube drawing frame comes downwards to stroke terminal, and begins next tube drawing stroke.Through above repetitive operation for several times, finally utilize this device that the steel pipe of being driven underground is pulled up, to realize the recycling of steel pipe.The great advantage of particularly utilizing wedge to clamp steel pipe is, it is big more to pull out resistance on the steel pipe, and clamping force is big more, thus make be driven underground on pull out the very large steel pipe of resistance and also can extract easily.
Four, description of drawings:
Fig. 1 is a pipe extractor structural representation of the present invention.
Fig. 2 is a hydraulic system structure schematic diagram of the present invention.
Five, the specific embodiment:
Hydraulic pipe drawing device as illustrated in fig. 1 and 2, form by hydraulic system, pipe extractor, hydraulic system as shown in Figure 2, hydraulic oil container 2 is fixed on the support 1, the hydraulic oil container oil-out has oil pump 4, the oil pump outlet is communicated with distributor 3, distributor is communicated with hydraulic jack 5, tube drawing frame 6 is housed on the hydraulic jack arm, and the tube drawing frame has pilot hole, is sleeved on the oil cylinder arm by pilot hole, have the big steel pipe jack in the middle of the tube drawing frame, by locking device 7 lockings, locking device is a wedge between jack and the big steel pipe, and Hydraulic Station is supplied with the hydraulic oil of 30mpa.By distributor fuel feeding about the pipe extractor oil cylinder, to realize moving up and down of oil cylinder arm.
