Abstract
The utility model discloses a large-caliber pipeline installation locator comprising an upper working surface, a lower working surface and a screw rod casing, wherein the lower end of the upper working surface is fixed with an upper screw rod, the upper end of the lower working surface is fixed with a lower screw rod, the upper screw rod is matched with the upper end of the screw rod casing and the lower screw rod is matched with the lower end of the screw rod casing. The large-caliber pipeline installation locator has the following benefits: by locating the upper screw rod, the screw rod casing and the lower screw rod of the installation locator inside a pipeline and attaching the upper working surface and the lower working surface that are identical with the inner wall of a pipe in curvature tightly to the inner walls of two pipes needing connection, the surface flatness of the pipe can be ensured and the gap between a hot melting belt and the surface of the pipe is reduced to the minimum, thus ensuring connecting quality and greatly improving the connecting speed of pipelines.
Description
Technical field
The utility model relates to installation positioner, more specifically says, it relates to a kind of large-diameter pipeline installation positioner.
Background technique
Heavy caliber is a kind of novel municipal drainage blow-off line with steel band enhanced polyethylene (HDPE) helical corrugation tubing with burying, it utilizes the steel higher modulus of elasticity, adopt special-purpose manufacturing mechanism, steel band is converted into inverted U, and the steel band of inverted U is curled into the curvature diameter of different size tubing by crimping machine, under the hot melt state, utilize in the Bond general of steel strip surface, outer field polyethylene material embryo and steel band are bonded into one effectively, produce inner wall smooth, internal and external layer is polythene material, the mesosphere is steel band enhanced polyethylene (HDPE) the helical corrugation tubing of steel band, and it is corrosion-resistant both to have kept polyvinyl piping materials, non-scaling, the water resistance coefficient is little, install easy to connect, advantages such as long service life.For keeping the mechanical property of steel band, when cutting, tubing need guarantee that steel band does not destroy, therefore the tubing section is not perpendicular with the axis of tubing, what bring thus is that tubing must be taken time when connecting the end face alignment of interconnective two tubing, dwindle two slits between tubing as much as possible, and guarantee the concentricity of two tubing; Because the connection of steel band enhanced polyethylene (HDPE) helical corrugation tubing is to adopt hot melt band heating and melting bonding technology, the hot melt band that is about to polythene material production is wrapped in two connections between tubing and sews on, resistance wire energising heating by the hot melt band, the polythene material of tube surfaces and the polythene material of hot melt band are melted, by the external force effect, with the polythene material of the polythene material of tube surfaces and hot melt band molten fully be one, after cooling off, finish the connection of tubing.Therefore, need the concentricity of two tubing of connection is whether tube surfaces is smooth, whether have the space will directly influence the quality of connection of tubing with the hot melt band
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of rational in infrastructure, simple to operate, effectively guarantee the large-diameter pipeline installation positioner of tubing flatness.
The purpose of this utility model is achieved through the following technical solutions: this large-diameter pipeline installation positioner, this positioning work piece comprises working surface, following working surface and screw mandrel cover, wherein go up the working surface lower end and be fixed with upper screw rod, following working surface upper end is fixed with down screw mandrel, connects by the screw mandrel cover between upper screw rod and the following screw mandrel; Upper screw rod is screw-thread fit with the screw mandrel set upper side and is connected, and following screw mandrel is screw-thread fit with screw mandrel cover lower end and is connected.
As preferably, describedly go up working surface, the curvature of the fitting surface of working surface is complementary with inner-walls of duct curvature respectively down.
As preferably, describedly go up working surface, working surface is to be close to pipeline splicing place respectively and is connected down.
As preferably, described screw mandrel cover footpath upwards is provided with push rod.
The beneficial effects of the utility model are: the upper screw rod by large-diameter pipeline installation positioner, screw mandrel cover, screw mandrel is in the tubing positioned internal down, to be close to two inwalls that need to be connected tubing with following working surface with the corresponding to working surface of going up of pipe material inner wall curvature, can guarantee the flatness of tube surfaces, the space of hot melt band and tube surfaces is reduced to minimum, with the assurance quality of connection, and can improve the speed that pipeline connects greatly.

Embodiment
Below in conjunction with drawings and Examples the utility model is described further.Though the utility model will be described in conjunction with preferred embodiment, should know, do not represent that the utility model is limited among the described embodiment.On the contrary, the utility model will be contained alternative, modified model and the equivalent in the scope of the present utility model that can be included in attached claims qualification.
Referring to Fig. 1 to Fig. 4, the large-diameter pipeline installation positioner of Jie Shaoing generally is used for the piping erection location here, yet should know that the utility model also can be used for other structures that needs installing and locating.This large-diameter pipeline installation positioner, comprise working surface 1, following working surface 5, screw mandrel cover 3, wherein go up working surface 1 lower end vertical fixing upper screw rod 2 is arranged, following working surface 5 upper end vertical fixing have following screw mandrel 4, described upper screw rod 2 and screw mandrel overlap 3 upper ends and are screw-thread fit and are connected, and described screw mandrel 4 down and screw mandrel overlap 3 lower ends and be screw-thread fit and be connected.As preferably, describedly go up working surface 1, working surface 5 is complementary with pipeline 7 inwall curvature respectively with the curvature of tube wall fitting surface down.As preferably, described go up working surface 1, down working surface 5 respectively with pipeline 7 between splicing place be to be close to and be connected.As preferably, described screw mandrel cover 3 footpaths upwards are provided with push rod 6.
During use, large-diameter pipeline installation positioner is inserted in the pipeline 7, specifically be radially positioned at pipeline splicing place of joining in twos, last working surface 1 and following working surface 5 match with pipeline 7 splicings place.By push rod 6 rotary screws cover 3, upper screw rod 2 and following screw mandrel 4 can stretch up and down, make that going up working surface 1 is close to splicing place of pipeline 7 mutually with following working surface 5, the smooth concentricity unanimity of tubing splicing place, at this moment the hot melt band of polythene material production being wrapped in two connections between tubing sews on, resistance wire energising heating by the hot melt band, the polythene material of tube surfaces and the polythene material of hot melt band are melted, by the external force effect, with the polythene material of the polythene material of tube surfaces and hot melt band molten fully be one, after cooling off, finish the connection of tubing.
