Description
Technical field
This utility model relates to pipeline extension fixture technical field, particularly relates to a kind of simple in construction, easy to use, little on the impact of city productive life pipeline dilator.
Background technology
10 years of the beginning of this century, are 10 years the soonest of domestic city process, and the scale of urban construction also present geometric growth at expansion progressively, the municipal drainage pipeline construction supporting with this.As the underground large artery trunks in city, municipal drainage pipeline assume responsibility for getting rid of the important task of municipal sewage, waste water and rainwater, and production and life impact on city are huge, and current domestic built flowing line is always about 350,000 kilometers.
And in municipal drainage pipeline, the pipeline using chemical material tubing to lay account for a biggest part, although the tubing of chemical material has the advantages such as coefficient of friction is low, corrosion-resistant, but due to the reason of material itself or the reason such as construction quality is defective, the deformation that can cause pipeline material is even caved in, this type of situation is the most relatively common at present, and the safe operation to drainage pipeline causes tremendous influence.
For the restorative procedure of produced problem in above-mentioned municipal drainage pipeline; current domestic conventional process technique is that local excavation processes; and local excavation processes and would generally bring the situation such as traffic jam, dust pollution; impact on city is bigger; therefore, problems annoyings the administration section of drainage pipeline networks always.
As fully visible, it is badly in need of a kind of good method at present and solves the deformation process problem of chemistry tubing drainage pipeline instantly, to reduce the impact on city productive life.
Summary of the invention
This utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of pipeline dilator, and it is applicable to the expansion to urban discharging pipeline, its simple in construction, easy to use, can effectively solve the deformation process problem to existing chemistry tubing drainage pipeline, and the impact on city productive life is little.
For solving problems of the prior art, the concrete technical scheme that this utility model uses is:
A kind of pipeline dilator, recovers panel including hydraulic jack, hydraulic support frame and arc；The axle head of described hydraulic jack is provided with a plate, one end of described hydraulic support frame and described connecting plate chain connection, the other end of described hydraulic support frame recovers panel pivot with arc and is connected, it is coupling part in the one end with hydraulic support frame hinge point that described arc recovers panel, the other end is arc working portion, and described arc recovers the coupling part of panel and is connected with the bottom hinge of hydraulic jack.
Preferably scheme, described hydraulic support frame and arc recovery panel are two, and are symmetrically distributed in the both sides of hydraulic jack.
Further preferred scheme, the bottom of described hydraulic jack is provided with traction apparatus, makes pipeline dilator enter pipe interior by the traction of traction apparatus.
Further preferably scheme, described arc recovers the arc surface that work surface is evagination of the arc working portion of panel.
By using such scheme, compared with prior art, it has the technical effect that a kind of pipeline dilator of the present utility model
1, this utility model movement by hydraulic jack axle head, and drive arc to return recovery panel by hydraulic support frame, thus realize the expansion to deformable duct, its simple in construction, easy to use, without the ground at deformation is excavated, the problem such as traffic jam, dust pollution will not be brought, the productive life of urbanite will not be brought impact, and lay a good foundation for the non-excavation rehabilitation of drainage pipeline, solve the drainage management department most thorny issue；
2, using arc to recover panel, during expansion, deformable duct will not be caused damage by arcwall face, good to the recovery effects of pipe deforming.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of this utility model a kind of pipeline dilator；
Fig. 2 is that the arc of this utility model a kind of pipeline dilator returns the curved working face schematic diagram recovering panel；
Fig. 3 is view during this utility model a kind of pipeline dilator entrance pipe interior；
Fig. 4 is the view during work of this utility model a kind of pipeline dilator.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage of greater clarity, below in conjunction with instantiation and referring to the drawings, this utility model is further described.It should be understood that these describe the most exemplary, and it is not intended to limit scope of the present utility model.Additionally, in the following description, eliminate the description to known features and technology, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figures 1 to 4, a kind of pipeline dilator, it includes that hydraulic jack 1 and the hydraulic support frame 2 being located at hydraulic jack 1 both sides and arc recover panel 3, described hydraulic support frame 2 recovers panel 3 with arc and is connected, described hydraulic support frame 2 and arc recover panel 3 and are two, and two sets are symmetrically distributed in the both sides of hydraulic jack 1.
The axle head of described hydraulic jack 1 is provided with a plate 4, one end of described hydraulic support frame 2 and described connecting plate 4 chain connection, the other end of described hydraulic support frame 2 recovers the middle part chain connection of panel 3 with arc, it is coupling part 31 in the one end with hydraulic support frame 2 hinge point pin joint 5 that described arc recovers panel 3, the other end is arc working portion 32, the work surface 33 of the arc working portion 32 that described arc recovers panel 3 is the arc surface of evagination, and described arc recovers the coupling part 31 of panel 3 and is connected with the bottom hinge of hydraulic jack 1.
In this utility model, the bottom of described hydraulic jack 1 is provided with traction apparatus, makes pipeline dilator enter pipe interior by the traction of traction apparatus.
Technological principle of the present utility model: this utility model utilizes the principle of hydraulic dilatation, recovers original deformable duct to circular pipe, and then be the feasible condition of the non-excavation rehabilitation creation in later stage.Its critical piece includes that the circular arc that hydraulic jack, upper and lower two panels are symmetrical recovers panel and hydraulic support frame.During construction, under traction auxiliary, at metamorphic manipulator traction to pipe deforming, and after fixing position, anamorphoser is positioned over centre position at deformation as far as possible, by the hydraulic support frame at the flexible drive processor two ends of hydraulic jack simultaneously to up and down or left and right is expanded, hydraulic support frame drive circular arc recover panel to pipeline up and down or left and right expansion, thus revert to circle by pipe deforming, complete the recoverable force work of pipeline.
This utility model can effectively solve the deformation process of chemistry tubing drainage pipeline instantly, it is to avoid the various impacts that trenchless rehabilitation is brought, the non-excavation rehabilitation for drainage pipeline is laid a good foundation, solve the drainage management department most thorny issue.
This utility model in use finds to there is also certain weak point, as it can operate with, the recovery of deformable duct processes, but it is not used to pipeline the gross distortion even process of Collapse defect, when using this technique simultaneously, need to carry out with pipeline external strengthening of foundation simultaneously, deformation otherwise may be caused cannot to have efficient recovery.Not enough to this, inventor is constantly improving, and makes this device become more consummate day by day.
The foregoing is only preferred embodiment of the present utility model; not in order to limit protection domain of the present utility model; all within spirit of the present utility model and principle, any amendment, the equivalent made, be all contained in protection domain of the present utility model within.
