Abstract

(57) [Summary] [Purpose] An object of the present invention is to provide a tube hanging jig that is easy to install and safe. [Structure] A jig that abuts against the inner surface of a pipe 11 and hangs the guide wire rope 1 having a grip portion 9 at the upper end and a stopper 8 protruding and fixed to the lower end of the guide wire rope 1 to hold the upper portion of the guide wire rope 1 inserted. Between the tool 2 and the lower holder 3, two outwardly bendable arms 6 and 7 are connected, and the arms 6 and 7 are connected by a bent portion holder 5 equipped with a pressing member 4 to hold the upper portion. The arm extension wire rope 10 is connected to the tool 2, and the guide wire rope 1 to be inserted into the tube 11 is hung by the gripping portion 9 and is driven by the lowering of the arms 6 and 7 by its own weight, and the pressing member 4 is moved. It is pressed against the inner surface of the pipe 11 and hung up.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pipe hanging jig used for pipe installation work or laying work at a construction site or a shipyard work site.

[0002]

[Prior Art]

 Conventionally, this kind of device has not been devised in particular, and when a large-diameter thin-walled pipe is suspended and moved, the suspending piece is welded to the pipe and a wire is attached to the suspending piece. It is known that ropes are connected and suspended by the operator's manual force or a chain block, or simply by tying the outer circumference of the pipe with wire ropes.

[0003]

[Problems to be solved by the device]

 As described in the prior art, suspending a pipe with a wire rope that locks the suspension piece requires the work of welding the suspension piece to the pipe, and it takes a long time to attach it to the pipe. The piece must be welded and removed after the pipe is installed or attached, and in that case, there is a problem that a scar of the weld cut remains at a place where the piece is attached.

On the other hand, it is dangerous to tie and suspend the outer circumference of the pipe with a wire rope, because if the wire rope is not sufficiently tied, the pipe may come off from the wire rope, and There was a problem that the wire rope and the pipe were rubbed and scratched when the product was taken out after it was installed at a predetermined position.

The present invention has been made in view of the above problems of the conventional technique, and its purpose is to ensure that the pipe can be easily attached and that the pipe is not damaged. It is intended to provide a high tube hanging jig.

[0006]

Means for Solving the Problems To achieve the above object, the present invention relates to a jig for abutting an inner surface of a pipe and suspending the pipe, wherein a stopper having a grip portion at an upper end and protruding at a lower end is provided. The guide wire rope to be fixed, the cylindrical upper and lower holders through which the guide wire rope is inserted, and the upper and lower holders are connected to each other at a plurality of positions so that they can be bent outwardly. Two arms to be connected, a bending part holder to which a pressing member for connecting and holding the bending part between the two arms is attached, and a wire for extending the arm to be connected to the upper holder The guide wire rope to be inserted into the pipe is hung by the grip portion, and the bending portion holder is projected outward by being driven by the lowering of the arms at a plurality of positions by its own weight. The pressing member Put press on the inner surface of the tube is made by hanging.

[0007]

[Action]

 Two arms connecting the upper holder and the lower holder make the bent portion holder project outwardly depending on the presence or absence of the tension of the wire rope.

When the guide wire rope is suspended by the grip portion, the stopper protruding to the lower end of the guide wire rope comes into contact with the lower holding tool and pushes up the lower holding tool so that the bending section holding tool faces outward. To project.

The lightweight and strong guide wire rope serves as a guide when the upper holding tool and the lower holding tool are moved up and down, facilitates portability of the tube, and maintains stability of suspension of the tube.

The wire rope for extending the arm that is connected to the upper holding tool is such that the two arms are extended straight from the bent state, and the guide wire rope can be inserted into and removed from the pipe.

[0011]

【Example】

 An embodiment will be described with reference to the drawings. As shown in FIGS. 1 and 2, a stopper 8 for projecting beyond the diameter of the guide wire rope 1 is provided at the lower end of the guide wire rope 1 having a grip portion 9 at the upper end. It is stuck.

Between the upper holder 2 and the lower holder 3 having a cylindrical shape through which the guide wire rope 1 is inserted, two arms 6 and 7 that are flexibly connected outward are connected, and two arms 6 are connected. , 7 as one set, three arms 6 and 7 are connected to the cylindrical outer surfaces of the upper holder 2 and the lower holder 3. Further, the wire rope 10 for arm extension is connected to the upper holder 2.

The bent portion between the two arms 6 and 7 is flexibly connected and held by a bent portion holder 5 to which the pressing member 4 is attached.

In this embodiment, when the pipe 11 is suspended, it is suspended by the wire extension wire rope 10 so that the two arms 6 and 7 are stretched in a straight line from the bent state. Insert the rope 1 into the tube 11.

In this state, when the arm extension wire rope 10 is moved to the guide wire rope 1, the stopper 8 at the lower end of the guide wire rope 1 abuts the lower holder 3 and is connected to the upper holder 2. The arms 6 and 7 bend under their own weight while descending, projecting the bent portion holder 5 between the arms 6 and 7 outwardly, and the pressing member 4 attached to the bent portion holder 5 causes the pipe 11 to move. It abuts the inner surface and is hung on the tube 11.

[0016]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. After inserting the guide wire rope with the arm extended in the pipe, the arm can be bent to easily suspend the pipe, and the work of welding the hanging piece to the pipe can be omitted and the pipe can be omitted. Safety is improved without damaging the tube and stabilizing the suspension of the tube by tying the outer circumference of the tube with a wire rope.
