Abstract

The utility model discloses a connecting pipe for underground bending pipelines. The connecting pipe is formed by at least one bending pipe at 175 degree, 165 degree or 150 degree through flanges in an assembling mode. During use, the connecting pipe can be used independently, or two sections of the connecting pipes can be connected to be used together, or more than two sections of the connecting pipes can be connected to be used together, and therefore a plurality of different bending angles can be formed in a combination mode and a 90-degree pipe can be formed by combining at most three sections of 150-degree connecting pipes. In addition, the bending angles are smooth. Therefore, the connecting pipes can be assembled on site according to conditions of the construction sites very conveniently during underground pipeline paving.

Description

Down-hole bending pipe connecting pipe

Technical field

The utility model relates under coal mine and lays pipeline.

Background technique

While laying Ф 108 with upper pipeline under coal mine, due to tunnel turn round and knick point many, therefore pipeline need to turn round and lay, and straight pipeline need to be processed into curved pipe.So scene, general Shi down-hole is approximately measured tunnel and is turned round and knick point angle, at the connecting tube of aboveground ground processing belt angle, be then sent to job location welding, the angle pipe of sometimes making is inaccurate, the phenomenon that repeats to do over again happens occasionally, for site operation brings difficulty.

Summary of the invention

In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide a kind of down-hole bending pipe connecting pipe.

A bending pipe connecting pipe, is characterized in that, it is at least assembled by flange by the pipe that turns round of following a kind of angle, and the angled pipe that turns round is 175 °, 165 ° or 150 °.

The utility model has the advantages that: during use, can be used alone, also can two joint uses that link together, or above uses that link together of two joints, so the some different angles of turning round of one-tenth capable of being combined, the most multiplex three save 150 ° can combine angle pipe in 90 °; And the angle of turning round is round and smooth.While therefore laying pipeline in down-hole, according to construction point situation Assembling, very convenient.

The utility model adds man-hour, as long as prescind respectively 5 °, 15 °, 30 ° on three-joint pipe, folds up and welds.

Fig. 2 is that the utility model angle is the bending pipe substructure schematic diagram of 165 °;

Fig. 3 is that the utility model angle is the bending pipe substructure schematic diagram of 150 °;

Fig. 4 is the connecting tube by the bending pipe sub-portfolio shown in two joint Fig. 3;

Fig. 5 is the connecting tube by the bending pipe sub-portfolio shown in three joint Fig. 3.

Embodiment

The bending pipe substructure of three kinds of different amount of the utility model as shown in Figure 1, Figure 2 and Figure 3.

The connecting tube of the 150 ° of bending pipe subgroups dress shown in Fig. 3 of take below further illustrates as example.

As shown in Figure 4, it is the connecting tube of β=120, turning that assembled by flange by 150 ° of pipes that turn round of two joints °;

As shown in Figure 5, it is the connecting tube that connects again γ=90, turning that the one 150 ° pipes that turn round form ° on the basis of Fig. 4;

Assembled relation of the present utility model is not limited to above-described embodiment, during use, can be used alone; Also can two the joint use that links together, by 5 °, enter level, be combined into some different angles of turning round, as 175 °, 170 °, 165 °, 160 °, 155 °, 150 °, 145 °, 140 °, 135 °, 130 ° etc.Add man-hour, as long as prescind respectively 5 °, 15 °, 30 ° on three-joint pipe, fold up and weld.

Claims

1.Yi Zhong down-hole bending pipe connecting pipe, is characterized in that, it is at least assembled by flange by the pipe that turns round of following a kind of angle, and the angled pipe that turns round is 175 °, 165 ° or 150 °.
