Description

[Detailed description of the invention] (Industrial application field) The invention relates to the improvement of minibus duct structures constructed in machine shops, etc., and more specifically, to accommodate electrical conductors such as power distribution cables and air piping. related to what was done.

(Prior art) Conventionally, in factories that mainly carry out machining, electricity, air (compressed air), water, steam, etc. are generally used as the primary power source for machines. Currently, it is being supplied to machines.

Wiring work for supplying electricity and piping work for supplying air are different types of work, so they are usually performed separately by respective construction companies.

FIG. 6 shows a conventional construction example for supplying electricity and air to a machine. As shown in the figure, a minibus duct 30 for supplying electricity is suspended from a beam of a building by a hanging device 31, and a plug-in breaker 32 is used to supply electricity to each machine via a branch cable 33. It's getting old. Moreover, the air piping 34 for supplying air is
It is suspended from a beam of the building by a hanging device 35, and a valve 36 allows air to be supplied to each machine via a hose 37. If these series of wiring and piping works are carried out at the same time on site, the work area will be limited and it will be dangerous, so it is necessary to carry out the wiring work and piping work at different times. be.

(Problems to be solved by the invention) The above-mentioned conventional technology has the following problems.

Since hanging tools are required to hang the minibus duct and air piping, the number of hanging tools increases, obstructing the upward view of the factory and creating clutter.

For work safety reasons, wiring work and piping work must be performed at different times, which lengthens the overall construction time.

Since the air piping is suspended at its middle portion, a steel pipe with a strong structure must be used as the material, resulting in high material and processing costs.

While minibus ducts have a unitized structure and can be repurposed easily, air piping has the disadvantage that it is difficult to repurpose because it is fabricated on-site each time.

(Means for Solving the Problems) The means according to the present invention for solving the above problems is such that the interior of the unit main body case having a certain length contains an electric supply chamber in which an electric conductor is housed and an air piping system. The air supply chamber is divided into two chambers, and a plug-in hole is provided in the front thereof, and both ends of the electric conductor accommodated in the electric supply chamber are protruded by a certain length on both sides of the unit main body having a certain length. Elbows are provided at both ends of the piping accommodated in the air supply chamber, and both ends protrude through the bottom of the unit main body case, and a joint pipe is provided in the middle of the piping, and the joint pipe is connected to the unit. It is characterized by protruding through the bottom of the main body case.

(Function) Since the present invention is constructed in this manner, the unit body case of a certain length, which accommodates the electric conductor and piping and is made into a unit, is carried to the site, installed and fixed at a predetermined location, and the electrical wiring work is carried out in the unit body case. Electrical conductors protruding from both ends are electrically connected via connecting members, while air piping, etc., are connected to the ends of steel pipes protruding through the bottom of the unit main body case with hoses, etc., to connect the main electrical wiring. and piping will be completed at the same time. Electrical wiring to each device is done using the plug-in holes provided on the front of the unit main case, while air piping, etc. are installed in the middle of the piping and are connected to joint pipes that protrude through the bottom of the unit main case. It is used to connect each device with piping.

(Embodiment) An embodiment of the present invention will be explained below with reference to the drawings. In Figs. Inside of case 1, partition plate 2
Upper chamber 3 for electricity supply and lower chamber 4 for air supply
It is defined as Inside the upper chamber 3, three electrical conductors (for example, power distribution cables) 5 for supplying electricity to load equipment (not shown) are housed with both ends protruding to a certain length on both sides of the unit main body case 1.
The electrical conductor 5 is made of copper, aluminum, or an alloy thereof. A plurality of spacers 6 are installed at predetermined positions in the upper chamber 3 at intervals, and the spacers 6 fixedly support the three electrical conductors 5 while electrically insulating them from each other. A plug-in hole 7 is provided at a suitable location on one side of the upper chamber 3. The method of supplying electricity from the electric conductor 5 to the outside is the same as that of the existing minibus duct, and is made possible by inserting a plug-in breaker, which will be described later, into the plug-in hole 7.

The lower chamber 4 of the unit body case 1 accommodates an air pipe 8 for supplying air to load equipment (not shown), and the straight pipe portion 9 of the air pipe 8 is made of steel pipes or hoses (including flexible ones). ) is produced by. Adjacent straight pipe sections 9 are connected to each other by branch piping teeth 10 arranged at regular pitches. The piping cheese 10 penetrates the lower surface of the lower chamber 4 and protrudes outside the unit main body case 1.
A joint pipe 11 for supplying air to the outside is connected to this.

A steel pipe 13 is connected to the end of the air pipe 8 via an elbow 12, and the steel pipe 13 is connected to the pipe cheese 1.
0, it penetrates the lower surface of the lower chamber 4 and protrudes out of the unit main body case 1, and is configured so that it can be connected to an air pipe in another unit main body case. In this way, the air piping 8 is fixed at a predetermined position fitting with a hole on the lower surface of the lower chamber 4 in order to enable piping connection to the outside. In order to ensure the integrity of the air piping 8, one side 14 of the lower chamber 4 is configured to be openable and closable using its lower end as a fulcrum, so that the air piping 8 can be easily accommodated in the lower chamber 4. .

The operation of this embodiment configured in this way will be described next. As shown in FIG. 2, this unit has an electric conductor 5 formed to a predetermined length with its ends protruding to a predetermined length on both sides of the unit main body case 1, while an air pipe 8 A steel pipe 13 with both ends penetrating the bottom of the unit main body case 1 and a joint pipe 11 provided in the middle thereof are in a state of penetrating the bottom of the unit main body case 1. The air and electricity supply minibus duct unit constructed in this manner is then delivered to the site in this state. When constructing electrical wiring and air piping at the site, the ends of the electrical conductor 5 protruding from both sides of the unit body case 1 are electrically connected by conventional means, as shown in FIG. The unit body cases 1 are connected to each other at the connecting part 15, and the air piping 8 is connected to the unit body case 1.
The steel pipe 13 that protrudes through the bottom of the 5th
As shown in the figure, they are connected by a connecting hose 17 having a universal joint 18. The air and electricity supply minibus duct unit thus connected is installed at a predetermined location using a hanging tool 19. As a result, the main electrical wiring work and air piping work will be completed at the same time. In this way, in the construction work such as electrical wiring and air piping, the work of the electricians involved in this work is simply the electrical connection of the electric conductors 5 protruding from both sides of the unit body case 1, while the work of the plumbing workers is Since it is a simple operation of connecting the steel pipe 13 protruding from the bottom of the unit body case 1 with the connecting hose 17, even if both operators work at the same time, they will not interfere with each other. Therefore, there is no waiting time between the two contractors, as would be the case if, for example, plumbing work is started after electrical work is completed. Next, electrical wiring and air piping to each device will be done in accordance with each worker's process, but they can also be done at the same time. First, to explain the electrical work, in Fig. 4, the work of attaching the feed-in breaker 20 to one end of the unit body case 1 and connecting the primary cable 21, the work of installing the plug-in breaker 23 to the plug-in hole 7, and the work of installing the plug-in Electrical wiring from the breaker 23 to each device is performed. Then, the operation string 22 is attached, the electrical performance of the feed-in breaker 20 is checked, and the work is completed. On the other hand, the air piping is steel pipe 13
The main valve 25 is attached to the main valve 25 and the primary air pipe 26 is connected to the air source (not shown), and the valve 28 is attached to the joint pipe 11 and the hose 29 is used to connect the main air pipe 26 to each device. The operation string 27 is attached to the main valve 25, and the piping work is completed. Electrical work and piping work are carried out in this way, but since the main electrical wiring and piping have already been completed and there are no shared parts for wiring and piping to each device, each work must be done independently. This makes it possible to carry out these works at the same time.

(Effects of the invention) As detailed above, according to the invention, an electrical conductor and piping are housed in a unit main case of a certain length, and both ends of the electrical conductor protrude for a certain length on both sides of the unit main case. At the same time, both ends of the piping protrude through the bottom of the unit body case, a joint pipe is provided in the middle of the piping, and this joint pipe penetrates the bottom of the unit body and protrudes to form a minibus duct for both air and electricity supply. So,
The main electrical wiring work and piping work are completed at the same time, and the common parts of the electrical wiring work and piping work for each device are eliminated, making it possible to carry out these works at the same time, eliminating mutual waiting time and shortening the construction period. It can be significantly shortened. By unitizing in this way, the hanging tools can be shared and the hanging tools can be omitted to a minimum, and
This has the effect of simplifying the layout of the factory by minimizing the space occupied by electrical wiring and piping within the factory.
