Description

Jig Apparatus for Steel Pipe and Fittings}

The present invention relates to a jig device for a steel pipe that can be supported on the surface of the steel pipe including a pipe fitting in the form of a deformed pipe or other operations in such a way that it is possible to support the rotary drive.

In general, the conventional jig device for steel pipe is configured to be suitable for use only in the steel pipe of the mainly straight tube type. In other words, in the case of a straight pipe, since both ends of the steel pipe have a vertical state, the jig device fixes the fixed member in a vertical state by moving horizontally. According to the shape, when both ends of the steel pipe are grounded, at least one end has an inclination angle rather than a vertical state, so that the fixing angle can be fixed only by displacing the inclination angle of the fixing member of the jig device to match this inclination angle. Due to the jig device of the straight tube steel pipe has a problem that can not be used in the deformed tube steel pipe.

In addition, even if the angle of inclination of the fixing member is provided to be used as a jig device for a release tube, if the rotation center of the fixing member cannot be adjusted due to the characteristics of the release tube, eccentric rotation is likely to occur during rotation operation, and as a displacement of the center of gravity. Due to the operation is not smooth, it is not suitable for use, and if the center of gravity is biased to one side, there is a problem in that the jig device has a bad effect on the service life due to the heavy ups and downs of the load.

In particular, when the diameter of the steel pipe is significantly changed, it is difficult to properly cope with the large change in the movement range of the jig, and this has caused problems such as a limitation in the application range.

The present invention has been conducted in order to solve the above-mentioned conventional problems, and an object thereof is to provide a steel pipe jig device that can be suitably utilized in various types of steel pipes regardless of the straight pipes or shaped pipes.

Another object of the present invention is to provide a steel jig device for preventing the adverse effects due to eccentric rotation in advance can be adjusted in accordance with the shape of the release tube.

Still another object of the present invention is to provide a jig device for steel pipes that can be used for various purposes regardless of the diameter of the steel pipes in various types of steel pipes including straight pipes and shaped pipes.

The operation of the jig device for steel pipes of the present invention configured as described above will be described by reference.

First, when the steel pipe P is to be mounted on the jig device of the present invention, as shown in FIGS. 10 and 11, a pair of jig devices are positioned such that the base 10 is positioned on both left and right sides of the trolley 9. However, the steel pipe (P) is moved to the position to be mounted by a crane (not shown) and in consideration of the size of the steel pipe (P) in advance to drive the wheel 11 located in the lower portion of the base 10 a pair of Roughly adjust the distance between jig devices. When the pair of bases 10 in the trolley 9 reach a predetermined suitable position, each of the brakes 12 is operated to maintain the brake 11 in a braking state so that the wheels 11 do not move anymore and, if necessary, for height adjustment. Operate the hydraulic cylinder 15 to adjust the height.

In such a state, the angle adjusting member 50 depends on the process of forward and backward movement of the rotary driving body 3 on the upper member 13 by the hydraulic cylinder 41, and whether the steel pipe P is a straight pipe or a deformed pipe. Adjusting the angle of inclination of the support plate 5 around the hinge portion 45 by adjusting the, and the fixing member (6) by the rotation operation of the screw rod members (62, 62) from the support plate (5) Through the slide movement operation of the steel pipe (P) to perform the process of positioning the correct position.

At this time, the opening groove 77 of the jig member 7 maintains the open state by separating the opening and closing member 79, and the hook of the crane for transporting and moving the steel pipe P is positioned in the opening groove 77. The jig member 7 is positioned to be in close contact with both ends of the steel pipe P by the forward operation of the rotary driver 3 described above. In this state, the hydraulic cylinder 75 on the jig member 7 is operated. The slider 73 is moved to the outside of the jig member 7, and at the same time, the remaining slider 73 is also moved outward by the angular rotation of the link member 74 and the driving plate 71. Jig (70) mounted on the other side of the) is also moved in the radial direction outside the jig member (7), due to this jig 70 reaches the inner surface of both sides of the steel pipe (P) to the mounting process to apply pressure to the outside At this time, on the hydraulic line supplied to the hydraulic cylinder (75) A piston rod of the hydraulic cylinder by closing the waste valve (75) so as not to move to disconnect the connector from the hydraulic cylinder 75 to separate the hydraulic line.

As such, when the process of mounting and fixing the steel pipe P to the jig member 7 is completed, the crane is adjusted and the hook of the crane is separated from the opening groove 77 from the steel pipe P, and then the inside of the guider 78. The opening and closing member 79 is inserted into the opening groove 77 to be completely sealed.

As described above, after fixing both ends of the steel pipe (P) to the steel pipe jig device of the present invention, it is moved to the position to perform work by using the bogie 9, if necessary, driving the rear of the housing (2) By operating the motor 34, the driving force is a rotational operation of the steel pipe (P) via the gears (36, 34). In other words, the specific process includes the rotary drive member 3, the rotary reciprocating member 4 meshed with the rotary drive member 3 and the spline portions 30 and 40, and the support plate connected to the rotary reciprocating member 4 ( 5), the fixing member 6 coupled with the supporting plate 5, the jig member 7 coupled with the fixing member 6, and the steel pipe P fixed to the jig member 7 are rotated. It is done.

As described above, regardless of whether the steel pipe (P) is in the form of a straight tube or a deformed tube, the fixing operation by the jig member 7 as well as the rotation operation by the drive motor 34 is made.

As described above, according to the present invention steel pipe jig device, regardless of the form of the straight pipe or the release pipe can be used appropriately in various types of steel pipe, in the case of the release pipe according to the shape of the fixing plate with respect to the support plate By moving the slide to move the position, the center of rotation can be adjusted as well as preventing adverse effects due to eccentric rotation. In addition, in the case of various types of steel pipe including a straight pipe or a deformed pipe, the jig member Since the installation position of the jig can be moved from the slider, it can be used for various purposes regardless of the diameter of the steel pipe, whether large or small.
