Model utility content
Main purpose of the present utility model is for the problems referred to above, channelling band roller garter spring in sleeve pipe is provided in a kind of push pipe crossing project, by setting up band roller garter spring at pipeline external, realize the pipeline that lays to roll in sleeve pipe advance, thus minimizing friction effectively prevents pipeline abrasion, ensure tube performance, increase the service life, improve efficiency of construction.
The utility model solves the technological scheme that its technical problem adopts:
In a kind of push pipe crossing project, in sleeve pipe, channelling is used and is with roller garter spring, it is characterized in that comprising the garter spring of clip outside described pipeline and 2 with upper roller, described roller is symmetricly set on garter spring bottom centered by the vertical center line of described garter spring, described roller supporting under application state on described internal surface of sleeve pipe, and really makes described pipeline and sleeve pipe coaxially arrange.
Described garter spring is connected and composed by fastening piece by two semicircle garter springs.
For the dicycly band roller garter spring of employing 2 rollers, the angle between the garter spring radius at 2 roller places is 60 °-90 °.
For the Three-wheel type band roller garter spring of employing 3 rollers, wherein 1 roller is arranged on bottom garter spring, and the angle between the garter spring radius being positioned at all the other 2 roller places of these roller both sides is 60 °-90 °.。
The beneficial effects of the utility model are: by setting up band roller garter spring at pipeline external, when carrying out pipe laying, realize pipeline and to roll in sleeve pipe advance, thus minimizing friction effectively prevents pipeline abrasion, ensure tube performance, increase the service life, and improve efficiency of construction.Especially be with roller garter spring can batch prefabricated, and install convenient, compare in sleeve bottom back-up sand or the form of construction work of laying the bed course such as steel plate, sandbag with traditional, engineering is simplified greatly, also plays the effect of raising efficiency of construction.

Fig. 1 is the structural representation of dicycly band roller garter spring;
Fig. 2 is the application schematic diagram of dicycly band roller garter spring in sleeve pipe in channelling;
Fig. 3 is the A-A sectional view of Fig. 2;
Fig. 4 is the structural representation of Three-wheel type band roller garter spring.
In figure: 1 garter spring, 11 semicircle garter springs, 12 bolt fastening components, 2 rollers, 3 pipelines, 4 sleeve pipes.
Below in conjunction with drawings and Examples, the utility model is described in detail.
Embodiment
Fig. 1-Fig. 4 illustrates channelling band roller garter spring and application thereof in sleeve pipe in a kind of push pipe crossing project, as Figure 1-3, the feature of this band roller garter spring is to comprise the garter spring 1 of clip outside described pipeline 3 and 2 with upper roller 2, described roller 2 is symmetricly set on garter spring bottom centered by the vertical center line of described garter spring, as shown in Figure 1, band roller garter spring in this example have employed 2 rollers 2, for the dicycly band roller garter spring of employing 2 rollers, angle α between the garter spring radius at 2 roller places is 60 °-90 °, 2 rollers are symmetricly set on both sides, garter spring bottom centered by the vertical center line of garter spring 1.Described roller 2 under application state is supported on the inwall of described sleeve pipe 4, and really makes described pipeline 3 coaxially arrange with described sleeve pipe 4.In practice of construction, coaxial setting must be realized, pipeline effectively can be avoided like this to run in the guide in sleeve pipe and occur transverse direction and lengthwise angle, ensure pipe laying quality.
In actual fabrication, described garter spring 1 is connected and composed by fastening piece by two semicircle garter springs 11.As shown in the figure, fastening piece have employed bolt fastening component 12, comprises bolt, nut, packing ring.Two semicircle garter spring 11 clips are outside pipeline 3, and its mounting edge is involutory, is affixed to together by bolt, nut, packing ring.Garter spring adopts steel plate to make.Roller adopts commercially available conventional products, according to the concrete operating mode such as channelling caliber, material, adopts suitable reinforcing type roller.
The above is dual-roller band roller garter spring and the application on pipeline thereof.In practice of construction, according to the concrete operating mode such as channelling caliber, material, for the situation that load-bearing is larger, be the support strength of reinforcing strip roller garter spring, reduce local pressure excessive, 3 rollers can be adopted.As shown in Figure 4, be a kind of Three-wheel type band roller garter spring.For the Three-wheel type band roller garter spring of employing 3 rollers, wherein 1 roller is arranged on bottom garter spring, and the angle β between the garter spring radius being positioned at all the other 2 roller places of these roller both sides is 60 °-90 °.
Fig. 3 shows the mounting arrangement of dual-roller band roller garter spring on pipeline.Band roller garter spring is evenly arranged in outside pipeline along pipeline axial parallel arranged, and the distance L between adjacent belts roller garter spring is 8-15m.Concrete distance value is determined according to pipe diameter, stressing conditions.To Three-wheel type band roller garter spring, the distance between adjacent belts roller garter spring is also 8-15m.Concrete distance value is determined equally according to pipe diameter, stressing conditions.
Adopt the band roller garter spring that provides of the utility model, when carrying out pipe laying, pipeline moves ahead to roll and instead of slip and move ahead in sleeve pipe, reduces friction and effectively prevents pipeline abrasion, ensure tube performance, increase the service life, improve efficiency of construction simultaneously.Especially be with roller garter spring can batch prefabricated, and install convenient, compare in sleeve bottom back-up sand or the form of construction work of laying the bed course such as steel plate, sandbag with traditional, engineering is simplified greatly, plays the effect of raising efficiency of construction equally.
The above is only preferred embodiment of the present utility model, not does any pro forma restriction to structure of the present utility model.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
