DETAILED DESCRIPTION OF THE INVENTION A manual hydraulic pipeworking machine 1 according to the present invention.
No. 0 performs the operation of forming the through hole 31 in the ground (see FIG. 4) and drawing the pipe 30 from the other end of the formed through hole 31 to one end.

The main body 11 of the plumbing machine has a size and weight that can be carried into a narrow work place 33 such as a groove or a bottom of a hole 32 excavated on the ground. In the case of the present invention, a portable hydraulic device such as a hand-operated hydraulic pump owned by many pipe manufacturers is used, and smooth workability in a minimum groove or hole 32 is required. In order to satisfy the two conditions (1) and (2), a compact and lightweight configuration is provided as long as practicality is not hindered.

In order to satisfy such conditions, the main body 11
It is necessary to set the size within a range of a size and a weight that enables almost one worker to enter the vertical hole and perform work preparation and plumbing work. For this purpose, the main body 11 needs to have a bottom frame 12 that can be stably placed in the work place 33 and a standing frame 13 that stands up therefrom. These may have a plate-like structure as well as a so-called frame shape, but bear a structure and strength against a force applied particularly during the pipe construction in the pipe axial direction.

The illustrated main body 11 has a substantially front gate type (substantially inverted U type).
It has a structure in which a front and rear through-type frame is bent into an L-shaped side surface to provide a bottom frame 12 and a standing frame 13 at the back. This is because it is possible to mount a member 17 having a punching head 17a longer than the main body 11 from the front or the rear of the main body 11. At the front and the center of the bottom frame 12, horizontal frames 14, 14 are provided in a beam shape. The size of the main body 11 of the pipeworking machine has a bottom frame length of 500 m so that it can be easily handled by one person.
m or less to the extent that a cylinder device 15 described below can be mounted,
As an example, it is desirable that the height is about 400 mm, the height is about 300 mm, and the body weight is about 10 kg or less and about several kg.

The above-described cylinder device 15 is installed in the main body 11. The cylinder device 15 has a telescopic rod 16 and is small in size to use the power of the manual hydraulic device (28) without difficulty and effectively. Through hole 31
Piercing head member 17 and extension member 18 for forming
Further, a holder 20 with a chuck for attaching the drawing member 19 for drawing the tube 30 into the through hole 31 is provided at the tip of the telescopic rod 16.

The holder 20 with a chuck is used to fasten a member such as the drilling head member 17 to a member receiver 21 attached to the tip of the telescopic rod 16.
It has a configuration in which the chuck members 22 are combined. It is desirable that the chuck member 22 be one in which a member such as the drilling head member 17 can be attached to and detached from the telescopic rod 16 by one-touch operation. In such a case, the stroke of the cylinder device 15 is short so that the drilling head and the like are repeatedly fed out. Operation can be performed easily.

In the case of the illustrated embodiment, the holder 20 with the chuck is provided with the member receiver 2 attached to the telescopic rod 16.
1 and a support frame 23 provided on both sides thereof and the chuck member 22 composed of an eccentric cam rotatably supported at the upper end thereof. Reference numeral 24 denotes a lever for rotating the chuck member 22 about an axis 25. The lever 24 presses the perforated head member 17 and the like between the concave member receiver 21 and the pressing surface 26 for increasing friction, and holds the punched head member 17 and the like integrally with the telescopic rod 16. Make it possible.

The cylinder device 15 for this purpose is simple in order to reduce the overall weight and not to complicate the connection and handling with the portable manual hydraulic device owned by many pipe manufacturers. It is desirable to use a dynamic compressor. Therefore, the cylinder device 15 incorporates the spring means 27 for return. Liquid pressure is supplied to the cylinder device 15 from a manual hydraulic pump 28 through a pipe 29. The hydraulic pump 28 is a general portable type, as already mentioned several times, and is operated by a hand lever 28a. 28b indicates a pump valve.

In order to form the through hole 31 using the apparatus of the present invention, the member 17 having the drilling head 17a and the extension member 1 are formed.
8 is used. At the end of each member, a male screw 34 and a female screw 35
There is a connection means such as a screw means consisting of: Each of the members 17 and 18 may be longer than the entire length of the main body, and the portal frame can be set in a skewered manner. The pull-in member 19 is for mounting a so-called poly pipe, that is, a polyvinyl chloride pipe or other pipe 30 and pulling the pipe 30 into the through-hole 31, and has a mounting member 36 for the pipe 30 at the tip.

Therefore, it is possible to excavate a groove or a hole 32 in the ground, easily carry the pipeworking machine 10 according to the present invention into a work place 33 such as the bottom thereof, and stably install the same. For installation, place the bottom frame 12 of the main body or attach the back frame 13 to the hole wall 37.
Or by fixing it to the work place 33 with an anchor. When a wall such as a groove or a hole 32 is used to receive the reaction force of the advancing force of the drilling head member 17, a receiving plate B may be disposed between the wall and the upright frame 13. See FIG. 6 (a). The drilling head member 17 is attached to the holder 20 by the chuck member 22 in a state of being most retracted. See FIG.

When the hand lever 28a of the hydraulic pump 28 is operated, the telescopic rod 16 is pushed out by the hydraulic pressure, and is eventually driven into the ground. When the telescopic rod 16 is fully extended, the chuck member 22 is opened and the pump valve 28b is opened to return the telescopic rod 16 to the contracted position by the action of the spring means 27, and the pump valve 28b and the chuck member 22 are actuated again underground. When the punching head member 17 is insufficient, the connecting means (3) is used.
4, 35), the extension member 18 is added, and the through hole 31 is formed.
To form See FIG. 6 (a).

After the through hole 31 is formed, the body 11 is first turned in the front-rear direction, and the frame 13 is arranged so as to hit the front wall. At this time, the support plate B may be arranged between the front wall and the upright frame 13. See FIG. 6 (b).

Next, the piercing head member 17 protruding from the other end of the through hole 31 is removed, and the retraction member 19 is attached instead, and the tube 30 is connected to the retraction member 19. The retraction is performed by repeatedly pressing and retracting the telescopic rod by applying an operating pressure, re-introducing the member 19 into the through-hole 31, and once moving forward and then backward. In many cases, the pipe 30 can be supplied from an inclined direction with respect to the through-hole axis. When the pipe 30 is pulled out to one end of the through hole 31, that is, the groove or the hole 32, the plumbing operation is completed.

Therefore, even if external work has already been performed, for example, a tiled entrance, if the work places 33 can be secured at both ends without destroying the external work, the through-hole 31 is formed in the ground between them. The tube 30 can be drawn into the formed and formed through hole 31. The present invention as described above is very effective for plumbing work performed on a place covered with a sidewalk, a waterway, a retaining wall, concrete or another construction surface that cannot be cut from the ground.

[0021]

Since the present invention is constructed and operates as described above, if only a hand-operated hydraulic device such as a hydraulic pump owned by many tubing companies is used, electric power and starting power can be obtained. The through hole can be formed in the ground without a machine set or the like, and the pipe can be drawn into the formed through hole. In particular, since the device of the present invention has a configuration suitable for miniaturization and weight reduction, even in a very narrow place surrounded by existing ground facilities , even a single worker involves excavation of the ground and destructive restoration of the existing facilities. Since plumbing can be carried out without any problems, good results can be obtained in a short period of time at a low cost without considering the influence on others.
