JPH07123558A - Duct for wiring/piping material equipped with running path for suspension vehicle, suspension vehicle and wiring/piping unit therefor - Google Patents

Abstract

PURPOSE:To lead in wiring/piping material in stabilized state while suspending in the center by ensuring a space for containing the wiring/piping materials in a duct and arranging the running paths on the opposite sides of the duct thereby running a suspension vehicle while supporting on the opposite sides thereof. CONSTITUTION:A rigid priming wire P is inserted into a duct 1 from one end thereof and connected, at the other end thereof, with a wiring/piping material X suspended from a suspension vehicle 2. The priming wire P is then pulled back and the suspension vehicle 2 runs on a running path 12 in the duct 1 thus leading in the wiring/piping material X while suspending up to one end of the duct 1. Subsequently, a tension rope P1 is pulled from the other side of the duct 1 to actuate the releasing means for the preceding suspension vehicle 2 thus falling the wiring/piping material X at a lead-in position in the duct 1. The released vehicle 2 moves toward the other end of the duct 1 and strikes against an adjacent vehicle 2 to actuate the releasing means thereof. The operation is repeated and the vehicle 2 is separated sequentially from the material X thus laying the material X.

It is designed to be maintained in a suspended state.
Further, the one end 21 of the engaging member 204 formed as the operating portion
When 0 is pressed, as shown in FIG.
Is rotated about the shaft 208, the engaging portion 209 retracts, the engagement with the tip of the arm portion 206 is released, and the suspension of the wiring / piping material X is also released. Such a suspension vehicle 2 is arranged at appropriate intervals with respect to the wiring / pipe material X, and travels in the pipe 1 along the travel path 12.

The pipe 1 and the suspension vehicle 2 for wiring / piping material of the present invention may be embodied as follows in addition to the above embodiment. Regarding the pipe 1 for wiring / piping material, for example, as shown in FIG. 8, a running path 12 may be formed in the middle of the pipe side wall 1a.
Further, as shown in FIG. 9, a traveling path 12 may be formed below, and further, as shown in FIG.
2 may be formed. The traveling path 12 is not limited to the one formed by projecting the pipe side wall 1a outward,
As shown in FIG. 11, the traveling path 12 may be formed by a ridge portion 1b protruding from the inner wall of the pipe 1. Further, the traveling path 12 is not limited to the one having the road surface on which the rollers roll. For example, as shown in FIG. 12, the traveling path 12 may be formed by a rod-shaped rail 121. In this case, the suspension vehicle 2 can be caused to travel along the traveling path 12 by the structure having the holding groove of the rail 121 and the roller 201 rotating on the vertical axis, for example.

As for the suspension vehicle 2, for example, FIG.

Further, as shown in FIG. 14, an end portion of the support plate 202 is cut out as a suspension means to form a hook portion 211, and a blade portion 2 is provided at the tip as a release means.
A sliding plate 2 that includes 12 and can freely move back and forth with respect to the hook portion 211.
It may be configured by 13. Sliding plate 2
One end 214 of 13 is formed as an operating portion, and slides the slide plate 213 by pressing from the lateral direction.

The pipe 1 for wiring / piping material of the present invention is
It is a tube that stores or protects wiring and piping materials such as electric wires, signal wires, hot and cold water supply pipes, gas pipes, electric wire pipes, various protection pipes, regardless of exposed pipes or buried pipes. The present invention is not limited to an integrally molded product, and includes a product formed in a tubular shape by combining a main body that houses wiring / piping materials and a lid, such as a duct.

Next, an example of a method of laying wiring / piping material using the pipe 1 for wiring / piping material and the suspension vehicle 2 will be described.

First, as shown in FIG. 15, a rigid nominal line P is inserted from one end of the pipe 1, and the suspension vehicle 2 is inserted at the other end.
The wiring / piping material X suspended at and the nominal line P are connected.
The suspension vehicle 2 and the call line P may be connected. Next, the call line P is pulled back, and the wiring / pipe material X is suspended and drawn into one end of the pipe 1 while the suspension vehicle 2 is traveling on the traveling path 12 in the pipe 1. At this time, the operating portion (one end 205 of the engaging member 204 shown in FIG. 3) for operating the releasing means for releasing the suspension of the wiring / piping material X provided in the suspension vehicle 2 is located on the side of the nominal line P. Suspension car 2
Send in. A flexible pulling rope P1 is attached to the suspension vehicle 2 at the top. This pull rope P1
Are connected so that the leading suspension vehicle 2 can be pulled in by the operation and the actuating portion of the leading suspension vehicle 2 can be operated. In addition, pull rope P
1 may be held upward by inserting it into a hole provided in another suspension vehicle 2.

Next, as shown in FIG. 17, the pulling rope P1 is pulled from the other end side of the pipe 1, and the suspension vehicle 2 at the top is pulled.
The operating part is operated and the releasing means is operated to release the suspension of the wiring / pipe material X, and the wiring / pipe material X is dropped to the retracted position in the pipe 1. At the same time, the suspension vehicle 2 becomes free and moves toward the other end side of the pipe 1, so that
Then, the operating portion of the suspension vehicle 2 is pressed to operate the operating portion. As a result, the suspension of the wiring / pipe material X of the adjacent suspension vehicle 2 is released, and the suspension vehicle 2 and the wiring / pipe material X are separated. While the same operation is repeated, the suspension vehicle 2 and the wiring / pipe material X are sequentially separated, so that the suspension vehicle 2 is recovered at the other end of the pipe 1 as shown in FIG. Can be installed in the tube 1.

In the above method, the pulling rope P1 is connected to the leading suspension vehicle 2, but the pulling rope P1 is connected to the last suspension vehicle 2,
It is also possible to pull from the one end side of the tube 1. In this case, one end of the pulling rope P1 may be pulled in when the call line P is pulled back.

If the leading suspension vehicle 2 is provided with a drive motor and is self-propelled, wiring without a calling line P is possible.
The pipe material X can be pulled in, and the suspension can be released by reverse running. As another laying method, a flexible tow rope is connected to the self-propelled suspension vehicle 2, and the pipe 1 is first drawn from one end to the other end, and the suspension vehicle 2 is suspended at one end of this tow rope. By connecting the suspended wiring / piping material X and pulling the other end of the tow rope with a towing machine, the wiring / piping material X is pulled into a suspended state and then the self-propelled suspension vehicle 2 is piped. It is also possible to adopt a method in which the wiring / pipe material X is released by suspending the wiring / pipe material X by running in the inside of the apparatus 1. This method has the advantage that a large suspension vehicle 2 does not require a large torque, and a small suspension vehicle 2 is sufficient.

Further, in order to facilitate the insertion of the rigid nominal line P (see FIG. 15) into the pipe 1 in the above laying method, as shown in FIG. 19, a passage 13 dedicated to the nominal line P is provided in the pipe 1. May be provided. As a result, the calling line P does not intersect with the existing wiring and piping materials in the pipe 1.

As described above, according to the present invention,
With the above configuration, when drawing multiple wiring / pipe materials at the same time or when drawing heavy wiring / pipe materials,
Wiring and piping materials can be installed easily and reliably when drawing in over long distances, and new wiring and piping materials can be drawn in without disturbing existing wiring and piping materials. The laying work can be easily performed.
