Abstract

The utility model discloses an underground pipe repairing tool, which aims at providing a hydrodynamical tube expander and uses hydraulic pressure to application of force uniformly, has little effect on the surrounding buildings in the operation process, and can realize the local repairing and whole renewal for the underground pipe. The hydrodynamical tube expander comprises a main body, a hydraulic cylinder, a supporting top foot, etc.; each side surface of the main body is provided with a hydraulic cylinder respectively, and the hydraulic cylinder is internally provided with a piston, a piston bar and a pressure spring. The main usage of the underground pipe repairing tool is to open or grind the pipes to be repaired through hydraulic effect, which can stably realize the local repairing or whole renewal of the pipe; the proper hydraulic motive expander is chosen according to the various diameters of the underground drainage pipe in the time of application.

Description

Tube expander surges
Technical field
The utility model relates to a kind of under ground piping fix tool, more particularly, is a kind of tube expander that surges of not trenchless rehabilitation under ground piping.
Background technique
The city subsoil drain is owing to be subjected to various external force loads for a long time, and section of tubing is long neglected and in disrepair in addition, damage phenomenons such as occurring easily breaking, be out of shape, subside.Main prosthetic appliance has pneumatic thatch, pneumatic broken pipe machine, the damaged machine of static(al) etc. at present, mostly be that a conical booster instrument is inserted in the old pipeline to be changed, after the booster instrument enters pipeline by pulling force or top power, with pipeline breaking, pipeline fragment with fragmentation is squeezed in the pipeline soil body on every side again, then, the new pipeline that is connected on the booster back is also laid by the method for drawing or push away.
Particularly, the booster head of Pneumatic immpacting booster process using is that inside pneumatic striking mechanism carries out booster under the pressurized air effect, and quiet pulling force booster technology makes the booster head by the attrition crushing pipeline by pulling force.These equipment all are to rely on dynamic vibration to carry out the purpose that random expansion reaches restoration updating, but its construction process relative complex, application of force inequality in the operating process, construction of structures is on every side caused certain influence easily, and can't repair the local damage of pipeline, can only satisfy the more new demand of pipeline rehabilitation of long distance.
The content of model utility
For overcoming shortcoming and defect of the prior art, the utility model provides a kind of tube expander that surges, and this equipment is working medium with hydraulic oil, utilizes hydraulic transmission, realizes the part and the whole updating of under ground piping by even expansion.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
It is made up of main body, hydraulic jack, a support pin etc.A hydraulic jack respectively is set on the side of described main body, is provided with piston, piston rod and pressure spring in the hydraulic jack.
Aforementioned body is six cylinders, and it is provided with towing pad and turnover oilhole; The oil circuit of described turnover oilhole leads to the lower end of a hydraulic jack of body interior, is sealed with sealing gland with extraneous joint; Evenly respectively on six sides of main body, the lower end of each hydraulic jack is provided with an oil transportation hole to described hydraulic jack, and the oil circuit in each oil transportation hole links to each other successively, forms a circuit oil duct in body interior; Described piston rod one end is connected, is positioned at hydraulic jack with piston, the other end is fixed on the support pin by screw; Described support pin has six, and correspondence is distributed in outside six sides of main body, and six support pin are the sealing cylinder shape when closely connecting; Described pressure spring is arranged on the piston rod outside.
Compared with prior art, the beneficial effects of the utility model are: stressed even during the tube expander that surges work, carry out well-regulated expansion, stable work in work can be avoided construction of structures is on every side produced damaging influence, can keep former pipeline location again, the reparation of real realization original position importantly can make pipe-repairing and former pipeline keep the identical gradient, guarantees the original function of use of pipeline, also when satisfying the requirement of long-distance pipe restoration updating, reach the purpose that fixed point is repaired broken pipe.
Description of drawings
Fig. 1 (a) and Fig. 1 (b) are sectional views of the present utility model;
Among the figure: main body 1, hydraulic jack 2, a support pin 3, piston 4, piston rod 5, pressure spring 6, towing pad 7, turnover oilhole 8, sealing gland 9, oil transportation hole 10
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Embodiment 1, operates the tube expander that surges, and utilizes jacking equipment to advance new pipeline simultaneously, realizes that by following three steps pipeline upgrades:
The first step, the tube expander that will surge is from the inspection shaft of renewal pipeline to be repaired or receive the well mouth and carry down, is positioned in the renewal pipeline mouth of pipe to be repaired under the interior cooperation of spying on equipment frequently;
Second step started the tube expander that surges, and by hydraulic conveyor hydraulic oil was transported in the hydraulic jack by the turnover oilhole, and the piston rod in the hydraulic jack is simultaneously protruding in the hydraulic jack under hydraulic pressure.At this moment, the support pin that is connected with piston rod is by the cement pipe fragmentation with renewal to be repaired of the energy of piston rod, and fragment is pressed into the peripheral soil body.
In the 3rd step, the propelling by distractor (wire rope or tube stretcher) traction or push-bench makes the new pipeline that is connected on the tube expander afterbody that surges along with the continuous pulverizing of old pipeline is advanced thereupon, is placed in original pipeline position.So process is back and forth carried out, and finally reaches to repair the purpose of changing old pipeline.
Embodiment 2, operate the tube expander that surges, and then the internal stress steel plate are fixed on the tube expander that surges, and realize pipeline rehabilitation by following three steps:
The first step, the tube expander that will surge is carried from pipe manhole or the receipts well mouth place of putting into that local damage is arranged, and is positioned in the pipeline mouth of pipe to be repaired; Under the interior cooperation of spying on equipment frequently, find out focus particular location and the damaged degree and the damaged size of pipeline, and select suitable internal stress steel plate in view of the above;
Second step, the internal stress steel plate that chooses to be tied up along the tube expander border of surging, the propelling by distractor (wire rope or tube stretcher) traction or push-bench is transported to affected area;
The 3rd step, start the tube expander switch that surges, by hydraulic conveyor hydraulic oil is transported in the hydraulic jack by the turnover oilhole, piston rod in the hydraulic jack is simultaneously protruding in the hydraulic jack under hydraulic pressure, the internal stress steel plate of tying up is strutted, and be close on the inwall of pipeline, utilize surface grout injection to fill the space of steel plate and pipeline enclosure to be repaired then.
In addition, the tube expander that surges can also cooperate with bench as adjustable reamer, uses in the small-bore pipeline construction and realizes disposable reaming, can accelerate speed of application, reduction of erection time.
