[Structure] A cylindrical support metal member 9 attached to the pipe 1 in a workable state before being vertically arranged, and an adjustment metal member 10 for adjusting a distance between the support beam 2 and the support metal member 9, These matching surfaces have at least two slopes 11 and 12 which are complementary to each other when they are expanded.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vertical pipe support device, which can be applied to support a suspended element of a land boiler.

[0002]

[Prior Art]

 In the suspended element of a land boiler, as shown in FIG. 3, in order to support the tubes 1 densely arranged in the vertical direction, a support beam 2 is arranged so as to sandwich the tube 1 and is supported by this. It is designed to be supported via the metal fitting 3. In FIG. 3, reference numeral 4 is a suspension rod for suspending the support beam 2, 5 is a seal band, 6 is a seal box, and L is a pipe pitch.

A specific example of tube support is shown in FIG. In FIG. 4, (a) is a view of the tube viewed from the same direction as in FIG. 3, and (b) is a view of the side surface thereof. In order to support the tube 1, after adjusting and setting the level of the tube 1, the cylindrical support metal 3 inserted into the tube 1 has its lower end in contact with the upper end of the support beam 2 It is attached by welding to 1. In such a mounting, the working environment is poor and the number of mounting steps is large when the tubes 1 are densely arranged.

In order to improve the workability in FIG. 4, in FIG. 5, the sleeve 7 and the screw type level adjustment hardware 8 are attached to the pipe 1 before setting, and the level is set after setting the pipe 1 and the support beam 2. The adjusting metal 8 is fixed to the sleeve 7 by closely contacting them with the sleeve 7 and performing non-rotating welding.

[0005]

[Problems to be solved by the device]

 In the conventional pipe supporting device, the structure of FIG. 4 has a small number of parts, but has a drawback that the number of steps required for mounting is large. On the other hand, the structure of FIG. 5 has a small number of mounting steps and improves workability, but the number of manufacturing steps of the supporting metal piece is increased, and therefore the cost of the supporting metal piece is high, and since the metal piece has a double structure, it is unnecessary The space, that is, the length of the pipe pitch L shown in FIG. 3 increases.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vertical tube supporting device which is low in cost, easy in operation, and mountable in a space similar to that of a conventional device.

[0007]

[Means for Solving the Problems]

 For the above object, according to the present invention, in a device for supporting a vertically densely arranged pipe, a cylindrical support metal member inserted into the pipe and fixed thereto, the support metal member and the support beam. And a cylindrical adjustment hardware inserted into the pipe between the support metal and the adjustment metal, and the matching surfaces of the support metal and the adjustment metal each have at least two slopes which are complementary to each other when they are expanded. A vertical tube support device is provided.

[0008]

[Action]

 According to the above means, the support metal fitting is attached to the tube in advance and the adjustment metal fitting is inserted. After setting the support beam, the adjustment hardware is rotated and brought into close contact with the support beam. Here, the support metal and the adjustment metal are fixed by anti-rotation welding.

[0009]

【Example】

 1 and 2, a vertical tube supporting device according to the present invention will be described in detail. The vertical pipe support device is composed of a support metal 9 and an adjustment metal 10 which are attached to the pipe 1 as shown in FIG. The support metal 9 and the adjustment metal 10 are characterized by the shape of these matching surfaces. That is, the matching surfaces each have at least two slopes 11 and 12 which are complementary to each other when they are expanded. Therefore, when the supporting metal piece 9 and the adjusting metal piece 10 are aligned, one cylindrical body is obtained, which is the same as the supporting metal piece 3 in FIG.

The attachment of the vertical pipe supporting device having such a structure will be described. First, the supporting metal 9 is attached to the vertically arranged pipe 1 by welding in a workable state before being arranged. . At this time, the adjustment metal fitting 10 is inserted in the tube 1 below the support metal fitting 9. Next, after setting the support beam 2 as shown in FIGS. 2 (a) and 2 (b), the adjustment hardware 10 is rotated to correct the error a at the time of installation. As shown in (4), a detent weld is performed on the matching slope between the support metal 9 and the adjustment metal 10.

The support metal 9 and the adjustment metal 10 can be manufactured by plate winding, cutting from a pipe, or casting.

[0012]

[Effect of the device]

 According to the present invention, the supporting metal object can be attached to the pipe first, so that the number of man-hours for attaching the supporting metal object after setting the pipe and the supporting beam can be reduced, and the cylindrical spacing adjusting metal object can be By adopting this, level adjustment and installation work become extremely easy, so no skilled worker is required. Furthermore, since the supporting device according to the present invention can be formed in the same size as the conventional supporting metal member, it can be mounted in a narrow space in the same manner as the conventional one, and it is necessary to change the design of peripheral devices. There is no.
