Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for positioning a cutting machine in automatic pipe cutting equipment.

[Conventional technology]

Conventionally, it has been used as a support frame for cutting machines when cutting slits into pipes using automatic cutting machines.
The one shown in FIG. 3 is used.

This equipment includes a frame-shaped pedestal 7 equipped with a running section 70 of a cutting machine The pedestal 7 can be positioned at any desired height by sliding it on the legs 8 and fixing it at a predetermined position. According to such equipment, the pipe to be processed Y is placed on the pipe support part 9, the pedestal 7 is positioned above it, and the leg part 8 is slid in the height direction according to the diameter of the pipe to be processed. After adjusting the height, the rotary roller 90 is rotated to center the pipe Y, and then the cutting machine X is moved on the running section 70 of the pedestal 7 to perform cutting.

[Means for solving problems]

However, such conventional devices have the following drawbacks.

It is necessary to adjust the height of the pedestal 7 each time according to the diameter of the pipe to be processed, but the height adjustment must be performed for each leg 8, and in addition, it is necessary to ensure the levelness of the pedestal. Therefore, the problem is that the work requires manpower and effort.

Since the structure is such that the weight of the pedestal 7 is always supported by the legs 8, the structure must be made sturdy due to the need for strength, which increases the weight of the device.

Depending on the slit length to be cut, it may be necessary to move the device along the length of the pipe. To move it in this way, the cutting machine must be removed from the stand, which is a time-consuming process. Furthermore, when the device is moved, the area in which the cut layer is scattered becomes wider, which requires more effort to clean.

The present invention was devised in view of these difficulties, and its purpose is to provide a device that can set the position of an automatic cutting machine in a short time with less effort.

[Means for solving problems]

For this reason, the device of the present invention has a horizontal pedestal having a running section of an automatic cutting machine, and is pivotably connected to the base via its lower end so that it can be raised and lowered, and its upper end is pivotally connected to the pedestal. It consists of a plurality of supporting legs, a trolley running section provided on the base along the direction of raising and lowering the legs, and a trolley for supporting the pipe to be processed that is movably disposed on the trolley running section, and the plurality of Its basic feature is that the horizontal pedestal is configured to be movable in the horizontal direction and height direction by having the legs of the horizontal frame form parallel links.

[Effect]

In such a device of the present invention, by raising and lowering the legs forming the parallel links, the horizontal pedestal is displaced in the horizontal direction and the height direction while maintaining the horizontal state.

The pipe to be processed is placed on a cart and positioned below the horizontal pedestal, and the lower part of the horizontal pedestal is brought into contact with the pipe by raising and lowering the legs. As a result, the horizontal pedestal is supported by the pipe to be processed and is positioned.

The pipe to be processed can be moved by the trolley in the direction in which the legs are raised and lowered, allowing the cutting location to be freely selected.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

The apparatus of this embodiment includes a horizontal pedestal 1 having a running section of an automatic cutting machine, a plurality of (four) legs 2 that support the horizontal pedestal in a tiltable manner, and It is equipped with a trolley running section 3 laid down and a trolley 4 for supporting the pipe to be processed, which is movably disposed on the trolley running section.

The horizontal pedestal 1 is composed of a frame member 10, and at both longitudinal ends of the horizontal pedestal 1, connecting shafts 11 to which leg portions to be described later are fixed are rotatably attached via supporting cylinders 13. It is provided. Also,
A pair of abutting portions 100, which are to be formed into a pipe Y to be processed, are formed along the length of the lower portion of the horizontal pedestal 1. In this embodiment, the frame member 10 in the longitudinal direction of the pedestal is constituted by an angle member provided with one side protruding downward, and the one side protruding downward is connected to the contact portion 100.
It consists of The horizontal frame 1 is provided with guide rails for the running section 12 of the automatic cutting machine along its length. A reinforcing plate 120 with holes is installed between the rails of this running section.
is provided.

The lower ends of the leg parts 2 are pivotally mounted on the surface plate 6 via the mounting parts 5 so that they can be raised and lowered, and the upper ends are fixed to each end of the connecting shaft 11 of the horizontal frame 1. A mounting cylinder 20 is fixed to the upper end of each leg 2, and is fixed to the connecting shaft 11 by fitting and fixing the mounting cylinder 20 onto the connecting shaft 11. The legs 2 supporting the horizontal frame in this way form parallel links,
Therefore, the horizontal pedestal 1 can be displaced in the horizontal direction and the height direction while maintaining the horizontal state according to the raising and lowering of the legs. It should be noted that the means for displacing the horizontal pedestal 1 may be any suitable means, but for example, it can be easily displaced by lifting one end with a crane (not shown) or the like.

The bogie traveling section 3 is laid down on a surface plate 6 below the horizontal mount along the up-and-down direction of the leg section 2.

The cart 4 includes a support portion 40 for the pipe to be processed;
It has running rollers 41 for running on the bogie running section 3, and is movably disposed on the bogie running section 3, so that the pipe to be processed Y supported by the support section 40 is moved to the horizontal frame 1. It is now possible to enter and exit from the area. The support section 40 has a structure in which the pipe Y to be processed is supported by rotating rollers 400, and by rotating the rotating rollers 400, the pipe Y to be processed can be rotated and centering of the cutting core can be performed. ing.

According to the device of this embodiment, by raising and lowering the legs 2 forming the parallel links, the horizontal pedestal 1 can be displaced in the horizontal direction and the height direction while maintaining the horizontal state. When cutting a pipe into a slit, the pipe Y to be processed is placed on the cart 4 and moved so that its tip is located below the horizontal frame 1. At this time, if necessary,
The pipe to be processed is rotated by the rotating roller 400 of the support section 40 to center the cutting core. Then,
The horizontal frame 1 is displaced in the pipe direction by tilting the legs 2 using a crane or the like, and the pair of contact parts 100 are brought into contact with the upper surface of the pipe Y. As shown in FIG. 2, the pair of abutting portions 100 abut the pipe Y to be processed symmetrically around its core, and as a result, the horizontal mount 1 is supported by the pipe itself and positioned. becomes.

In this state, slit cutting is performed by the automatic cutting machine X running on the running section 12. In addition, in this cutting, if the movement stroke of the cutting machine is shorter than the cutting length, the horizontal frame 1 is once lifted from the pipe Y to be processed using a crane or the like, and the pipe Y to be processed is moved the required distance using the trolley 4. The horizontal pedestal 1 is again lowered onto the pipe Y to be processed, and slit cutting is continued.

[Effect of idea]

According to the present invention described above, the following effects can be obtained.

Depending on the diameter of the pipe to be processed, by raising and lowering the legs, the horizontal pedestal can be displaced in the horizontal and height directions, and the position can be set, including height adjustment, simply by placing it on the pipe. Therefore, the work can be performed with less effort and manpower. With the conventional equipment shown in Figure 3, it took two workers about 45 minutes to cut one section of the pipe, from marking to removing the pipe. This work can be done by one worker in about 20 minutes.

Since the weight of the horizontal pedestal is supported by the pipe to be processed, there is no need to increase the strength of the pedestal or the legs, and the device can be made smaller and lighter.

Even if the length of the slit to be cut is large, it can be easily cut by simply displacing the horizontal pedestal in the horizontal and vertical directions and moving the pipe to be processed supported by the trolley in the length direction. There is no need to move the entire device along the length of the pipe to be processed. Furthermore, since the device is not moved, the cutting work area is limited, which is advantageous for cleaning cutting debris, etc.
