Description
Technical field
The utility model relates to escape field, tunnel, particularly a kind of plastics pipe for escaping.
Background technology
The communications and transportation cause such as railway, highway construction of China obtains flourish in recent years, and railway, high-grade highway circuit are by mainly taking the form of Tunnel Passing during the mountain ridge.And in constructing tunnel process, when complex geologic conditions, difficulty of construction is large, construction risk is high, very easily occur the catastrophic failures such as landslide, roof fall, prominent mud water burst of closing the door, the constructor near face is often trapped in the inside by this type of landslide, causes rescue work very difficult.For this reason, pipe for escaping should be pre-set in IV, V, VI grade of country rock location during Ministry of Railways's regulation constructing tunnel.
In escape pipe design, what employing was maximum at present is steel pipe, finds through long-term site inspection, and the shortcomings such as steel pipe is easily out of shape as pipe for escaping existence under impact load, unit volume is heavy, interface is many, blow-by are selected in job site.Compared with steel pipe, plastic pipe (comprising polyethylene, polypropylene, polyvinyl chloride etc.) has suitable elastic-plastic deformation, easy to connect, long service life, resisting environmental stress and cracking, lightweight etc. superiority.Plastic pipe is used not only to effectively reduce the weight of pipe for escaping as escape tube, the in-site installation being simultaneously more conducive to escape tube moves operation with tearing open, and the plastic pipe intensity of high-quality is high, good toughness, can meet the requirement of the security performances such as pipe for escaping intensity and shock resistance.
The connection of current pipe for escaping adopts flange plate type to connect more, i.e. the excircle of flange is provided with multiple bolt hole, is arranged on by flange after on pipeline, adopts bolt to be fixed together by the flange on two pipelines.Adopt this structure, connection bolt quantity is many, and fitting operation is wasted time and energy.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of and had not only facilitated attended operation, but also can ensure highstrenghtpiston's pipe for escaping that escape tube joint is connected firmly.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of highstrenghtpiston's pipe for escaping, be formed by connecting by multistage plastic pipe, fixed by connector between adj acent plastic tubing, described connector comprises the first flange and second flange of docking setting and is looped around flange excircle week for fixing the clip of the first flange and the second flange; The end that connects of described first flange and the second flange is respectively arranged with the radial flange stretching to clip; Described clip is be equipped with two semicircular structures mutually, and two semicircle clips are fastened by bolts, and the inner peripheral surface of clip are provided with the groove of equipped first flange and the second flange radial flange.
Above-mentioned highstrenghtpiston's pipe for escaping, the end face that described first flange connects with the second flange is provided with towards the axial chimb of the second flange, the end face that the second flange connects with the first flange is provided with the axial concave edge that axial chimb is equipped mutually with the first flange.
Above-mentioned highstrenghtpiston's pipe for escaping, the junction of described radial flange and the first flange outer end is provided with rounding off part.
Owing to have employed above technical scheme, acquired by the utility model, technological progress is as follows.
Connector of the present utility model have employed the form of structure of the supporting flange of clip, both facilitates attended operation, can ensure again the connectivity robustness of pipe for escaping joint, be more conducive to on-the-spot safe handling; Application of the present utility model, decrease the quantity of bolt in conventional flange connection, and shell ring is better to fixed effect, junction stability is improved greatly, the more important thing is the minimizing of bolt quantity, make fast easier for installation, decrease cost of labor, improve operating efficiency.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
The utility model is formed by connecting by multistage plastic pipe, be fixedly connected with by connector between adj acent plastic tubing, connector comprises the first flange 1, second flange 2 and clip, first flange 1 docks with the second flange 2 and arranges, shell ring around the excircle of flange, for fixing the first flange and the second flange.
The external diameter of the first flange and the external diameter of escape tube match, the end that connects of the first flange and the second flange is provided with the radial flange 11 stretching to clip, the junction of radial flange and the first flange outer end is provided with rounding off part 13, the setting of rounding off part, stress when can prevent flange and clip from assembling concentrates the generation causing connector to damage phenomenon.
In the present embodiment, for strengthening the bonding strength of adjacent channel, the end face that the first flange 1 connects with the second flange is arranged towards the axial chimb 12 of the second flange, as shown in Figure 1; The end face that second flange 2 connects with the first flange arranges axial concave edge 22, as shown in Figure 2; The axial concave edge 22 of the second flange 2 is equipped with axial chimb 12 phase of the first flange.
Clip is be equipped with two semicircular structures mutually, the both ends of semicircle clip 3 are provided with picking up the ears outwardly, be provided through bolt hole 32, two semicircle clips 3 of picking up the ears on picking up the ears by the bolton of cross-under in bolt hole, the structure of semicircle clip as shown in Figure 3.The inner peripheral surface of the utility model clip is provided with groove 31, groove has specific dimensions, can be connected after the radial flange of a pair flange closely cooperate fixing.
Fig. 1 is the structural representation that two plastic pipes are connected by connector, during assembling, can be first connected with the first plastic pipe 5 by the first flange 1, be connected with the second plastic pipe 4 by the second flange 2, one end of flange is connected by welding manner with plastic pipe; Again the first flange is connected with the second flange socket joint, then clip is installed on the radial flange of two flanges, finally use bolt 6 by two semicircle clamp connections together.
