Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a tube support.
More specifically, the present invention relates to a pipe support base that is used to support two pipes when connecting two pipes in the case of constructing a gas pipe or a water pipe, and can finely adjust the support height.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, two gas pipes 1 and 1'are connected by using an electrofusion joint 2, or when the butt connection is made by a butt fusion machine. It is necessary to support 1'at a predetermined height using the tube support 3. 2 of the tube support used in this case
Examples are shown in FIGS. 6 and 7.

The pipe supporting base shown in FIG. 6 comprises a fixed part 4 and a movable part 5, and the fixed part 4 is arranged on the underframe 6 with a spacing sufficiently wider than the diameter of the maximum diameter pipe of the target pipe 1. And two inner pipes 7 and 7'are provided vertically, and the inner pipe
Springes 8 and 8'which are longer than the inner pipes are inserted in the pipes 7 and 7 '.

The movable portion 5 is provided so as to cover the outer peripheries of the inner pipes 7 and 7'of the fixed portion 4 so as to be slidable up and down, and the upper end is closed by a blind lid 9a. 9 ', and a roller 10 supporting the tube 1. A boss 12 for supporting the roller shaft 11 and a locking screw 1 are provided below the outer pipes 9 and 9 '.
3 and a boss 14 having a screw hole for supporting the screw 3.

The boss 1 of each outer pipe 9, 9 '
Reference numeral 2 respectively supports and fixes the ends of the roller-shaft 11 which supports the roller 10. Locking screws 13 each having a lock handle 13a are screwed into the bosses 14, respectively. When this pipe support is used, the pipe 1 is supported on the roller 10, the height thereof is adjusted, and then the locking screw 13 is tightened, and the outer pipes 9 and 9'are made inner.
Fix to pipes 7, 7 '.

Further, in the pipe support base shown in FIG. 7, a pipe 16 having a screw formed on the outer periphery is vertically provided on the underframe 6.
A nut body 17 having a handle 17a is screwed into the pipe 16, and a support member 19 having a pair of rollers 18, 18 'arranged in a V shape is provided on the upper portion of the nut body 17.
Is rotatably provided. When used, the tube 1 is supported by the rollers 18, 18 'arranged in a V shape, and the handle 17a is rotated to move the nut body 17 up and down to adjust the height.

[0007]

Although the conventional pipe support shown in FIG. 6 is inexpensive, the height of the pipe 1 is set to the outer pipe 9 by the spring pressure of the springs 8 and 8 '. Since 9'is moved up and down for adjustment, it is necessary to carry out fine adjustment for a pipe heavier than the spring pressure of the springs 8 and 8'while supporting the pipe 1 by hand. Therefore, a large-diameter tube (particularly, a nominal diameter of 200 A) has a heavy weight (about 60 kg at 200 A), and there is a problem that it is difficult to perform adjustment while supporting it by hand.

Further, in the tube support base shown in FIG. 7, when adjusting the height, it is not necessary to carry out fine adjustment by manually supporting the tube because it is adjusted with screws, but the H dimension (tube support height) There is a problem that it cannot be lowered. Also, increase the stroke amount (H
If the dimensions must be in the range of 100 to 270 mm), the minimum height of the H dimension cannot meet H = 100 mm when the male thread dimension is adjusted to the maximum height.

In view of the above-mentioned conventional problems, the present invention realizes a pipe support base which does not need to support the pipe by hand when finely adjusting the height and can secure a predetermined stroke amount (270 mm-100 mm = 170 mm). With the goal.

[0010]

The pipe support base of the present invention comprises a fixed portion and a movable portion provided on the fixed portion so as to be movable up and down. It comprises two inner pipes fixed vertically on the underframe at a predetermined interval, and one of the two inner pipes has an internal thread formed on the inner surface thereof. Is a pair of outer pipes that cover the inner pipe and are slidable up and down, a roller shaft whose both ends are fixedly connected to the lower portions of both outer pipes, and a roller rotatably supported by the roller shafts. And a screw shaft rotatably provided inside one of the outer pipes and screwed into the female screw of the inner pipe, and a rotating handle attached to the upper end of the screw shaft. To do. In addition to that, a side roller is rotatably provided on the outer periphery of each outer pipe.

By adopting this construction, it is possible to obtain a pipe support base which does not need to support the pipe by hand when finely adjusting the height and which can secure a predetermined stroke amount.

1 and 2 are views showing an embodiment of the present invention. FIG. 1 is a plan view and FIG. 2 is a sectional view taken along line II-II of FIG. As shown in the figure, this embodiment is composed of a fixed portion 20 and a movable portion 21. The fixing portion 20 is provided with a base frame 22 having a substantially rectangular planar shape, and a pair of the base frames 22 which are vertically provided on opposite sides of the base frame 22 and are spaced apart from each other by a predetermined distance (a dimension equal to or larger than the maximum diameter of a target pipe). Inner pipe 2
3, 23 '. A female screw is formed on the inner side of one inner pipe 23.

The movable part 21 is an inner member of the fixed part.
Outer pipes 26, 26 'which cover the outer circumferences of the pipes 23, 23' and are slidable up and down and have a boss 25 for supporting and fixing the roller shaft 24 in the lower part, and rotatably supported by the roller shaft 24. The inner pipe 23 is provided on the roller 27 and one outer pipe 26.
And a side roller 29, 29 'rotatably provided on the outer circumference of the outer pipe 26, 26'.

The screw shaft 28 is rotatably supported by a bearing collar 30 provided on the upper end of the outer pipe, and a handle 33 is provided on the upper end of the screw shaft 28 via a handle mounting collar 31 and a handle bar 32. Has been. Also, the side rollers 29, 29 'are the outer pipes 26,
Clips 34, 34 'fitted on the upper and lower parts of the 26' are regulated so as not to come off.

The present embodiment having such a configuration is used as shown in FIGS. 3 and 4. First, as shown in FIG. 3, both the large-diameter pipe and the small-diameter pipe are placed at the center of the roller 27 as shown in 1a. However, due to bending of the pipe and other reasons, one side of the roller 27 (the screw shaft is Place it on the outer pipe side). Then, as shown in FIG. 4, the screw shaft 28 is rotated by rotating the handle 33 to adjust the height of the roller 27 together with the outer pipe 26 and the pipe 1
The a or the tube 1b can be positioned at the desired height.

In this case, since the vertical movement of the roller 27 is adjusted by the screw shaft 28, a predetermined stroke amount can be obtained, and the operation force of the handle 33 with respect to the load is light, and even a large diameter pipe can be easily moved up and down. Yes, there is no need to manually support the tube as before. Also, fine adjustment is easy. The side rollers 29, 29 'can guide the pipe 1a or 1b when moving it back and forth, reduce the friction in that case, and facilitate the movement.

[0017]

According to the present invention, since the roller for supporting the pipe can be vertically moved and adjusted by the screw shaft, a desired stroke amount can be obtained and the pipe can be manually connected during the connecting work. There is no need to support it, and fine adjustment becomes easy, which can contribute to rationalization of piping work.
