Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of assembling a piping system in which the entire piping system including body control valves and the like is divided into a plurality of piping groups and assembled.

Conventionally, when assembling a piping system that includes fluid control members such as pulp, pipes are prepared by cutting or bending pipes to a predetermined length, fluid branching members such as bent joints, T-shaped joints, cross-shaped joints, etc. Fluid control members such as pulp are prepared as assembly members. These assembly members are stored on pallets or the like by type or by assembly part. This pallet has a shape convenient for sorting, storing, and transporting assembly parts, and is transported to a predetermined assembly position by a transport means such as a crane or a transport vehicle. The assembly process is carried out on a flat plate in a workshop equipped with various equipment such as an overhead crane, a welding machine, and an impact renote. The assembled parts are taken out onto a flat plate from the pallet transported to the assembly position, the mutual arrangement of the assembled parts is determined, and the assembly is performed using the various devices described above. After the assembly is completed, the assembly parts are moved further upstream to the assembly position trench, sorted and sorted into another /4let, and the assembly parts are assembled one after another.

To form a piping system in the assembly process as described above, a reference point is set on the flat plate where the assembly process begins, and from this reference point, the pipes are positioned and tightened sequentially upstream. Perform assembly work such as

Therefore, the upstream assembly process cannot be started until the downstream assembly process is completed. Therefore, if there is an accident where there are not enough assembled parts at the assembly location, all assembly processes will be suspended until the assembled parts are taken out of the warehouse, transported by crane, etc., and replenished. It has its drawbacks. Furthermore, if assembly errors accumulate, misalignment will occur in the upstream assembly process, so there is a drawback that positioning operations must be made so that the assembly errors are always settled at the position calculated from the reference point.

An object of the present invention is to provide a method for assembling a piping system in which the assembly process is divided into blocks by dividing the piping system into a plurality of piping groups and supporting the piping groups on respective surface plates.

The present invention divides the piping system into a plurality of piping groups.

The piping system is a two-layer, three-layer, etc. stacked piping system on a flat surface, but piping that is extremely far above the flat surface is handled as a piping system on a separate plane (the same applies to vertical surfaces). The divided piping group is positioned on a surface plate of a predetermined size and is supported on this surface plate in a detachable manner, and predetermined assembly parts are attached thereto. A piping system is obtained by sequentially arranging the piping group to which assembly parts are attached and the surface plate, so the assembly work is completed by connecting the piping group on the sides of the surface plates.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the method for assembling pipes, etc. of the present invention will be described below in detail with reference to all the drawings.

In Figure 1, P is the piping system, and piping system P is the piping group P.
It has a planar structure that can be divided into I-Pros, and the piping level has two layers: low-level mounting and high-level mounting, and the pipes mounted on the low level and the i4 pipes mounted on the high level intersect with each other. , or can be connected with a joint member such as a T-joint for branching. Piping groups P1 to P20 are provided with hardware such as pulp 21.

Another assembly component is a pipe 76 (hereinafter referred to as pipe member 24) which is made into a pipe, and the entire piping system P is configured.

To divide piping system Pi into piping group P, -p2o, use surface plate 1
The dimensions of the pipe members 24 are determined in consideration of the mounting dimensions of the metal fittings so that they terminate at an edge-to-nip on the pipe members 20.

Two to three supporting members 23L, 23H, etc., each having a length corresponding to a determined piping level, are welded to the pipe member 24.... As shown in FIG. 2, the support members 23L and 23M can be fixed by fitting into the support needles 23 . . . in vertical and horizontal rows on the surface plates 1 to 20. The support members 23L..., 23H are used as legs to be welded to the module frame, which will be described later.

When another pipe member 24 is installed directly below the pipe member 24 provided at a different mounting level, the pipe members 24.
24 corresponding position 24a.

Weld it to 24b. FIG. 4 shows the connector 25a.

25b is a cross-sectional view of the connector 25b, in which the connector 25a is provided with a groove 26.26 that opens outward at the neck portion of the flap 27. When the connector 25b is inserted into the connector 25b, the grooves 26, 26 open and are caught in the grooves provided on the inner peripheral surface of the connector 25b to be connected.

Next, the assembly process will be explained.

The unprocessed long pipe is cut to a predetermined size and then bent. (cut and bent) 4-ib member 24

H: Fully welded. Also, if necessary, connect the connector 25a.
, 25b, etc. are welded. - and both ends of the eve member 24... are machined into a 7-run shape so that the cornion joint 22 is completely attached, and the union joint 22... is attached. At this time, the necessary T-joints and hardware such as the pulp 21 are also assembled into the main tube member 24. This process is called the tube processing process. The pipe members 24 after the pipe processing process are mass-produced and classified according to various shapes.

The above-mentioned gear member 24 is clamped with a shaft roller Ql shown in FIG. 5 and transported onto the surface plate 1.

The pipe center Q+ has the function of rotating the clamped member 24 at any angle or moving it forward, backward, left and right, and determines the upper position of the surface plate 1 of the pipe member 24, and supports the support member 23L... is fitted onto the support needle 23 planted on the surface plate 1 and supported. Note that the pipe member 24 in the embodiment shown in FIG.

The piping system assembly method according to the present invention has the following effects.

(1) Since the piping system including one fluid valve on its side is divided into a plurality of piping groups, it has the feature that a complex piping system can be formed as a combination of relatively simple piping groups. Therefore, standardization and mass production of piping groups is possible.

(2) Since the pipe group is supported on the surface plate, accidents such as missing assembled parts can be prevented, and delays in the entire assembly work due to accidents can be completely prevented. In addition, since the necessary work information for each process such as transportation and positioning can be digitized, it is suitable for automatic control by a computer or the like.

(3) Since a support needle is provided on the surface plate and the position of the pipe can be set automatically, there is no need to increase the accuracy of setting the pipe security.
