Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for dividing a long steel pipe into cartridge drums, which is used in industries mainly manufacturing and processing steel and manufacturing machines and workpieces. It relates to a winding device.

[Conventional technology]

As is well known, steel pipes are used in large quantities for various purposes in various industries.

The steel pipe usually has a predetermined length, e.g.
Although it is manufactured and sold as a straight pipe with a length of approximately 1.5 m, various types of connection means are often required for each use, and when a connection joint is not used, methods such as welding, crimping, or gluing are used.

Therefore, in order to reduce the number of joints and welding points and to reduce construction costs, it is desirable to use as long a steel pipe (hereinafter simply referred to as a pipe).

However, straight pipes are uneconomical because the longer they are, the higher the handling costs during transportation and processing are. Therefore, by winding a long pipe into a coil and supplying it, processing costs and transportation costs for installation can be reduced. Aiming at this reduction, a method and apparatus for manufacturing long pipes have been developed and are disclosed in Japanese Patent Application Laid-open Nos. 125326/1980 and 427027/1980, respectively.

With the apparatus and the method described in JP-A-60-127027, pipes with an outer diameter of 13.8 mm or more can be manufactured. Therefore, the outer diameter
Taking a 17.3mm pipe as an example, one drum has approximately 700m.
The length is wrapped.

When the long pipe is packaged as one drum in this way, long-distance transportation costs can be reduced, but handling is not easy during use because the drum size is large and heavy. Therefore, a method is adopted in which the long pipe is divided into small drums and wound up into appropriate lengths before use, and each small drum is transported to the required location before use.

Now, an example of a blast furnace taphole oxygen hole opening device in which a pipe is wrapped around such a small drum and used in a cartridge style is as follows: a pipe with an outer diameter of 16 mm is wrapped around a cartridge drum for 100 to 150 m, and then There is an example in which the pipe is used while being straightened into a straight pipe.

FIG. 5 shows an outline of the apparatus for wrapping the pipe around the cartridge drum in the above example.

As shown in FIG. 5, the long pipe 1 is wound around a large drum 2, and the large drum 2 is rotatably supported by a bearing device 3.

The long pipe 1 passes through a brake roll 4,
The cartridge drum 6 is wound around a cartridge drum 6 which is rotatably supported on a bearing device 5 and is driven by a drive device such as an electric motor 7.
The required length is wound up by the rotation of .

[Problem that the invention seeks to solve]

The inventors of the present invention, who have carried out a number of operations for winding the long pipe 1 in sections on the cartridge drum 6 using a pipe winding device as shown in FIG. Therefore, in order to reuse the long pipe 1 that has been deformed and irregularly wound as shown in Figure 6, it cannot be wrapped neatly around the cartridge drum, and a large amount of new equipment investment and large amounts of money are required to correct and shape the pipe. I learned that labor costs are necessary.

Therefore, if the long pipe 1 is one that has undergone heat treatment, such as a colorized steel pipe,
Unbelievable twists and bends occur, making subsequent reuse extremely difficult.

An object of the present invention is to prevent deformation of the cross section of the pipe when winding a long pipe, particularly a long pipe in a coiled form, into parts on a cartridge drum, and to do so in an orderly manner even if the long pipe is severely twisted and bent. It is an object of the present invention to provide a pipe winding device that can straighten the pipe and wind it around a cartridge drum.Another object of the present invention is to provide a pipe winding device that allows pipe winding to be carried out safely and with good working efficiency.

[Means for solving problems]

The pipe winding device according to the present invention, which achieves the above object, is a pipe winding device that divides a long pipe wound around a large drum into cartridge drums and winds them, the cartridge drum being detachably attached to the pipe winding device. a drum support device that pivotally supports the cartridge drum and rotatably drives the cartridge drum via a drive device;
A frame rotatably supports a pipe straightening bending roller having two support rollers arranged at a predetermined interval and a pressure roller located between the support rollers; and a guide device for reciprocating and transversely transporting the pedestal in a section corresponding to the winding width of the trige drum.

[Effect]

The drum support device according to the present invention is configured to removably support the cartridge drum and to rotatably drive the cartridge drum via the drive device, so that the drum support device can safely and securely support the cartridge drum. It is possible to quickly wind the pipe, and it is also easy to replace a completely wound cartridge drum with an empty cartridge drum.

In addition, a long pipe that is twisted or bent can be easily straightened by a frame that rotatably supports a pipe straightening bending roller that has two support rollers and a pressure roller located between the support rollers. Since it can be straightened into a tubular shape, pipes with excellent shapes can be continuously supplied to the cartridge drum.

Next, the guide device movably supports the pedestal and reciprocates the pedestal across a section corresponding to the cartridge drum winding width. Moreover, since there is no disturbance in the winding, the pipe itself will not be twisted or bent.

〔Effect of the invention〕

In the pipe winding device of the present invention, a pipe straightening bending roller is provided between a large drum and a cartridge drum, and a pedestal on which the pipe straightening bending roller is supported is connected to a guide device for winding the cartridge drum. Since the structure is such that the pipe is reciprocated and horizontally fed across a section equivalent to its width, the pipe that has been wound around a large drum and curved is first straightened into a straight line by a pipe straightening bending roller, and then straightened by a guide device. Since it is fed horizontally, it can be wrapped around the cartridge drum in an orderly manner.

Therefore, it has the effect of dramatically increasing the practical use of coiled long pipes, and the economic effects thereof are significant.

Furthermore, the device is easy to operate, highly safe, and extremely useful in practice.
