Description

Pipe Corrector {Device for pipe correction}

The present invention relates to a pipe straightener that straightens a curved pipe and at the same time removes concrete stuck to the pipe.

Curved pipes are often generated at construction sites, and concrete is often attached to curved pipes generated at construction sites.

Korean Utility Model Registration No. 157798 has been disclosed as a conventional technology for straightening a curved pipe.

However, the conventional technique is a technical feature that the work of calibrating the pipe and the work of removing concrete at the same time, the effectiveness of the problem in the case of calibrating the pipe.

In other words, the pipes mainly used in construction sites are thick because they are mostly used as supports, and even when the work is forcibly unrolled, they try to return to the original bent state due to their elasticity.

Therefore, the conventional technology has the advantage that can be done at the same time to remove the concrete, but in terms of straightening the pipe can be seen as the same as the job of straightening the pipe by hand.

Therefore, the present invention is intended to provide a pipe straightener that can not only simultaneously correct curved pipes and remove concrete, but also improve the effectiveness of pipe straightening.

That is, the present invention was intended to prevent the pipe from being restored to the bent state by elasticity by applying a force to the bent pipe while applying a shock while rotating the pipe in a straightened state.

In the above, it is preferable that the impact members form a cylindrical shape and the impact members are rotatably provided on the body. Although the impact members may be used in a stationary state, the impact members rotate by the pipe to come into contact with the pipe to mitigate the impact the pipe receives from the impact members as well as the durability of the impact members themselves. Also preferred for.

Hereinafter, the configuration and operation of the present invention will be described in detail.

1 is a perspective view of one embodiment according to the present invention, Figure 2 is a schematic diagram of another embodiment according to the present invention shown to show the principle of operation of the present invention.

For convenience of description, the following description will be made with reference to FIGS. 1 and 2.

The curved pipe 20 is inserted into the body 10.

Normally, the bent pipe 20 is used as a support for a construction site, and its outer diameter is produced in the same way. Therefore, the present embodiment will be described based on the curved pipe having the same outer diameter.

However, even when the outer diameter of the bent pipe is changed, the present invention may be applied by changing the rotation center of the chuck or changing the position of the impact members.

The bent pipe 20 is fixed by the chuck 30, and the chuck 30 is rotatably provided in the body 10.

The chuck 30 has a hollow 31 formed therein so that the bent pipe 20 can be inserted therein.

In addition, the chuck portion 30 is provided with a chuck 32 capable of biting the pipe 20 inserted into the hollow 31.

In the case of FIG. 2, as the chuck 32, a bolt coupled to a bolt hole formed in the chuck part 30 is presented, and the front end of the bolt allows the pipe 20 to bite the pipe 20 by advancing the bolt. The chuck is generally used as a shelf.

In the case of the chuck provided on the shelf, as well as the technology of fixing the workpiece by moving the respective claw (claw), as well as the technology of the interlock chuck that a plurality of claws are linked at the same time is widely known.

The chuck 32 is sufficient to be able to fix the pipe 20, the technical configuration can be variously changed by those skilled in the art.

Therefore, since the pipe 20 is fixed to the chuck 30 by the chuck 32, the pipe 20 and the chuck 30 are rotated together.

The chuck 30 is driven by the rotating means.

2, the motor 40 and the electric gear 41b which rotates in association with the motor, and the chuck part 30 which rotates in conjunction with the electric gear 41b are shown.

In the case of FIG. 1, the motor 40 and the electric chain 41a rotating in conjunction with the motor and the chuck unit 30 rotating in conjunction with the electric chain 41a are illustrated.

1 to 2 are only one embodiment, various rotating means may be considered. In other words, those skilled in the art can apply a variety of rotation means to rotate the chuck portion, changes or adjustment of such rotation means is within the scope of the present invention.

The body 10 is provided with a plurality of impact members.

In this embodiment, the impact member is composed of a stationary rotating roller 50 and the transfer rotating roller (60).

The stationary rotating roller 50 and the conveying rotating roller 60 are provided on the body 10 in a state parallel to the pipe 20, and are rotatably provided on the body 10 as a cylinder.

Since the stationary roller 50 and the transfer roller 60 are generally in contact with the outer circumferential surface of the pipe 20, when the pipe 20 rotates, the stationary roller 50 rotates to some extent by the contact thereof.

The stationary rotating roller 50 and the conveying rotating roller 60 form a shape surrounding the pipe 20, and in the case of FIG. 1, two stationary rotating rollers 50 and one feeding rotating roller 60 are provided. In the case of 2, one stationary roller 50 and one feeder roller 60 are provided.

That is, in the case of FIG. 1, the impact members form a triangle shape to surround the pipe 20, and in FIG. 2, the impact members are disposed to face each other to surround the pipe 20.

The impact member conveying means 70 is provided in the body 10 so that the conveying roller 60 is spaced apart from the pipe 20.

Before inserting the bent pipe 20 into the body 10, the conveyance rotating roller 70 is conveyed upward by the impact member conveying means 70.

After the bent pipe 20 is inserted into the body 10 and fixed by the chuck part 30, the conveying roller 60 is moved to its original position by the impact member conveying means 70, that is, with the outer circumferential surface of the pipe 20. Transfer it to the position where it is usually in contact.

The bent pipe 20 is forcibly straightened to some extent by the conveyance of the conveying roller 60.

However, if the pipe 20 is to be calibrated only by the transfer of the transfer roller 60 in this manner, the pipe 20 is returned to the bent state again when the transfer roller 60 is removed by the restoring force by elasticity. will be.

The curved pipe 20 is straightened to some extent by the feed roller 60 which is conveyed by the impact member conveying means 70, and then the pipe 20 is rotated.

The pipe 20 is rotated and hit continuously with the impact members, that is, the stationary rotating roller 50 and the transfer rotating roller 60, the elastic restoring force is removed by this impact, that is, the plastic deformation.

As the impact member conveying means 70, a hydraulic mechanism or the like provided on the support bearing of the conveying roller 60 can be assumed, but this is only an embodiment.

In the middle portion of the stationary rotating roller 50 and the transfer rotating roller 60, a plurality of supporting rollers are placed in order to prevent bending due to the rotational impact of the pipe 20.

Concrete and the like buried in the pipe 20 is separated in the process in which the pipe 20 hits the stationary rotating roller 50 and the transfer rotating roller 60.

In addition, reference numeral 80 of FIG. 1 is a device for unfolding the support plate coupled to the pipe support, and the support plate coupled to the pipe support is generally flat because the thickness thereof is very thin compared to the pipe, so that it is well spread only by giving a strong force in one direction. .

According to the experiment, when the pipe is rotated at about 180 rpm (using a motor reduction ratio of about 10: 1), when the pipe is rotated for about 5 seconds, the pipe is changed to a normal straight state, and it is not bent again by the restoring force.

The present invention can provide a pipe straightener that can not only correct curved pipes and remove concrete, but also ensure pipe straightening.
