each nylon belt 2 is respectively wound on one pipeline 6 (specifically beside the port of the pipeline) needing to be aligned;

two ends of each nylon belt 2 are locked and fixed through a ratchet locking device 1;

the plurality of cross beams 3 are located on the same side of the two nylon belts 2 (i.e., the side facing the pipe to be aligned) and are in contact with the surface of the pipe 6 to be aligned.

The utility model discloses in, on specifically realizing, many crossbeams 3 are each other, for equidistant distribution.

In the utility model, in the concrete implementation, one end of each beam 3 is fixedly connected with two ends of a nylon belt pressing plate 4 through pressing plate screws 5;

the nylon strap 2 is pressed in place between the cross beam 3 and the nylon strap pressing plate 4.

The utility model discloses in, on specifically realizing, crossbeam 3's extending direction is parallel to each other with the axis direction of pipeline 6.

The utility model discloses in, in the concrete realization, the port (need welded port promptly, welded junction) of two 6 relative sides of pipelines is located the position between two nylon belts 2.

It should be noted that, for the present invention, one end of each nylon strap 2 is fixedly connected to one end of the ratchet locker 1 (for example, as shown in fig. 2, a connecting hole or a connecting column bound thereon);

the other end of each nylon strap 2 is wound and fixed on the ratchet locker 1 (for example, the other end can be wound on the ratchet wheel of the ratchet locker 1 and pressed and fixed by the ratchet wheel pressing handle which is hinged with the two ends of the ratchet wheel and can rotate). Here, it should be noted that the structure of the ratchet locker is the conventional structure. The ratchet locker can be any one of the conventional ratchet lockers for tightening a rope, and is a conventional mechanical locking device.

In particular, the ratchet locking device 1 may be a conventional truck-mounted tightener (tensioner) produced by Shanghai ordinary factories, and may be other types of conventional locking devices with ratchet wheels.

It should be noted that, to the utility model discloses, it is the device of the group error that subducts of being convenient for.
