Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for fixing electric wires, cables, piping and the like to a wall surface.

[0002]

2. Description of the Related Art Wires such as electric wires and cables, and fluid pipes such as gas, liquid and powder (hereinafter referred to as long bodies) are laid in an appropriate environment such as a dedicated pipe. In other cases, it is often necessary to lay in unsuitable or harsh environments. When laid in such an environment, for example, vibration caused by automobiles, factory power, etc., hydraulic power caused by water flow such as when laid in sewers, waterworks, etc., and other natural and artificial external forces In addition, the laid cables and pipes may vibrate and move, causing various damages due to them, and may not be able to perform their functions sufficiently during the lifetime, that is, may deteriorate the soundness.

Therefore, conventionally, when laying in such an environment, the cables and tubing after laying are arranged at regular intervals in order to suppress damage to the cables and pipes and to ensure soundness during the service life. It is tied to a nearby facility or the like with a string or the like, or a wall fixing device 5 such as a saddle metal fitting, an anchor bolt, a U-shaped metal fitting is attached to the wall 4 as shown in FIG.
A method for fixing the piping 1 is employed.

However, in the conventional fixing method, since it depends on a manual operation by a human, it is limited to a case where the installation is performed in a laying environment in which the human can work. Therefore, there is a problem that cables and pipes laid in an environment where humans cannot work cannot be fixed to the surrounding wall surface, so that they are easily damaged during the service life and the soundness of the cables and pipes is deteriorated. For example, there is a case where cables and pipes are laid in a pipe having a pipe diameter of about 1 m or less, which is difficult for a person to enter and work. On the other hand, recent technological innovations have made remarkable progress in robot technology, so even in a laying environment where humans could not work conventionally, it is possible to efficiently lay and fix cables and piping using these technologies. It became.

[0005]

However, in the conventional method of fixing cables and pipes, it is assumed that manual work is performed by a human. Therefore, the cables and pipes are fixed by a robot using the conventional fixing method as it is. It is difficult. That is, in the conventional fixing method, relatively large fixing points, such as saddle fittings, anchor bolts, U-shaped fittings, etc., as shown in FIG. Although it was firmly fixed to the wall 4 such as the wall at the installation site, the robot at the present stage lacks the working ability in terms of dexterity compared to humans, so the fixing method of these wall fixing devices 5 cannot be adopted as it is. .

Also, in terms of size, the size of the conventional wall fixture is extremely large for the robot to be used. Therefore, from the viewpoint of using a small robot to work in a narrow place, the size is reduced. There is a need. Therefore,
The present invention solves this problem and provides a fixing method suitable for fixing cables and pipes by a robot.

[0007]

According to the present invention, there is provided a method of fixing a long body to a wall surface, wherein a plurality of linear body locking members are arranged in a predetermined position of the wall surface for fixing the long body in the longitudinal direction. Then, the long body is disposed in the vicinity of the linear body locking tool, and the long body is locked to the linear body locking tool by the linear body, so that the long body is It is characterized by being fixed to a wall surface.

For example, in a method of fixing a long body along a wall surface, a portion at a fixing start position of the long body is brought into contact with a position to be fixed on the wall surface, and a linear body locking tool is provided. The linear body is fixed to the wall in the vicinity of one side surface of the portion of the elongated body that has been brought into contact with the wall, and the linear body is restrained by the linear body restraining portion of the fixed linear body locking tool. A portion of the elongate body at a position moved by a fixed distance from the fixing start position is brought into contact with a position to be fixed on the wall surface, and the linear body locking tool is brought into contact with the wall surface of the elongate body. A linear body restraint of a linear body locking member fixed to a wall surface near the other side surface of the portion and the constrained linear body is fixed to a wall surface near the other side surface across the long body The elongated body is restrained and tensioned, and this process is repeated until the fixing end position of the elongated body is reached. In two rows along the vicinity of both sides of the elongated body, with the linear body restraining portion of the linear body locking tool intermittently fixed to the wall surface, in a state of straddling the elongated body alternately, By being restrained and tensioned, the elongated body can be fixed to the wall surface, which is particularly suitable when a robot is used.

That is, instead of the conventional method of fixing a long body to a wall with a relatively small number of fixing points using a relatively large wall fixing device, a linear body and a relatively large size for restraining the linear body to the wall are used. Suitable for robot work by adopting a method of fixing a long body to the wall using the frictional force between the linear body, the long body, and the wall using a small linear body locking tool A fixing method can be used. In addition, the use of a small-sized linear body locking device generally decreases the fixing strength at each fixing point, but in this case, the number of fixing points per unit length is increased, and the same as the conventional case. The fixing strength of the entire long body can be secured.

[0010] The linear body locking device includes a distal end portion having a function of fixing to the wall surface and a linear body restraining portion at the head having a function of restraining the linear body. The tip portion may be a nail-shaped one that is driven and fixed, a screw-shaped one that is fixed by screwing, a one that is fixed by bonding with an adhesive, solder, or the like. The linear body restraining portion may be an anchor-shaped one that hooks and restrains the linear body, or a needle-shaped one that has a perforation and restrains the linear body therethrough.

As long as the linear body has strength and life that can fix the long body over its entire life,
A string made of stainless steel wire or other metal wire, plastic, fiber or the like may be used. Further, the tape may be in the form of a tape, and various tapes such as metal, plastic, and fiber can be used.

According to the present invention, it is of course possible to improve the efficiency of the fixing work of the long body, and even in a laying environment where the long body could not be fixed conventionally, it is possible to fix the long body to the wall surface. Damage during the life of the long body can be suppressed. Further, the size of the fixing portion can be made smaller than before, and a relatively large number of long members can be laid for a fixed laying volume, so that the utilization efficiency of the laying space is improved. In addition, unlike the related art, the risk of the elongated body hanging down in the middle of the fixed point is extremely reduced, and when the elongated body needs to be removed, it can be easily removed by cutting the linear body. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The same elements are given the same numbers, and duplicate descriptions are omitted.

(Embodiment 1) In this embodiment 1, a cable 1 is first laid in a conduit made of concrete inside a nuclear facility that is dangerous because it is contaminated with radioactivity using a pipeline work robot. , 30 m. The robot used in the first embodiment operates by remote control,
The robot itself can be fixed to the inner wall of the pipeline at the designated position, moved in the pipeline, a cable can be drawn into the pipeline, and a fixing operation described later can be performed.

Elongated body 1 to be laid and fixed in Embodiment 1
Is a natural rubber sheath with a diameter of 10 mm and a capacity of 200
V, 100A power cable for emergency power supply. As shown in FIG. 1 to FIG. 3, the linear body locking tool 2 used has an anchor-shaped linear body restraining portion for hooking and restraining the linear body 2 on the head, and a leg portion. Is a so-called hook having a tip portion having a function similar to that of a nail for driving and fixing it to a wall surface and having a total length of 1 cm. Linear body 3
Is a 0.5 mm diameter stainless steel metal wire.

First, the robot grips the power cable 1 supplied from the drum placed at the end of the pipeline, first,
It is pulled into the conduit made of concrete and positioned at the laying position. Next, the robot moves to the fixing start position of the power cable 1 located at the laying position, and presses a portion of the power cable 1 at which the fixing start position of the power cable 1 is to be fixed to the wall surface 4 of the pipe to be fixed. The power cable 1 is gripped, pierced into the wall surface 4 of the pipe near one side of the power cable 1, and the hook 2 serving as a linear body locking tool is driven into a depth of 7 mm and fixed. The stainless metal wire 3 is restrained by passing it through an anchor portion of the hook 2 which is a linear body restraining portion.

30c from the fixing start position of the power cable 1
The robot is moved by m, and the portion of the power cable 1 to be fixed is pressed against the wall surface 4 at the position where the pipeline is to be fixed and gripped, and a hole is drilled in the wall surface 4 of the pipeline near the other side surface of the power cable 1. Then, hook 2 which is a linear body locking tool is
mm, and the stainless steel wire 3 restrained by the hook 2 on one side is connected to the power cable 1.
The power cable 1 is fixed to the wall surface 4 by being restrained by being passed through an anchor portion which is a linear body restraining portion of the hook 2 fixed to the other side and strung so as to straddle the power cable 1.

This fixing operation is repeated for 30 m from the fixing start position to the fixing end position of the power cable 1,
The hook 2 is fixed to the wall surface 4 at a position where the cable 1 is alternately sandwiched at intervals of 30 cm, and the stainless metal wire 3 is attached to the anchor portion which is the linear body restraining portion of the hook 2 so as to straddle over the power cable 1. The power cable 1 is fixed to the wall surface 4 by being restrained and tightened. FIG. 1 shows a part of the state where the power cable 1 is fixed to the wall surface 4.

This fixing work requires a long time due to the problem of radiation exposure in human manual work. However, according to the present invention, the fixing work can be completed in a relatively short time without any problem of radiation exposure. According to the first embodiment, when a robot is used but there is no suitable one, it is of course possible to wear a protective suit for avoiding radioactivity and then perform a human operation.

According to the first embodiment, the cable is laid indoors. However, the present invention is not limited to this. Further, the present invention is not limited to the air, and may be underwater or seawater. Further, it may be on the ground or underground. It may be inside a ship, an aircraft, a large machine, or the like. According to the first embodiment, the cable 1
Although a power cable is used as the above, the present invention is not limited to this, and a communication cable may be used. The piping is not limited to a cable, but may be a liquid such as gas, water, or petroleum, a powdery material such as cement or sand, a granular material, or a semi-fluid pipe such as silicone oil. However, it is preferable that these can be wound around a drum and handled for convenience of the fixing operation.

Further, according to the first embodiment, the hook is used as the linear body locking member 2 and is fixed to the wall surface 4 by striking it. However, the present invention is not limited to this.
A screw may be formed at the tip of the device, and the screw may be fixed to the wall surface 4 by screwing. Alternatively, a method in which an adhesive surface is formed at the tip and fixed to the wall surface 4 with an adhesive, solder, or the like may be used. Further, a system in which the linear body 3 is fixed by the same principle as that of the stapler may be used.

The linear body restraining portion of the linear body locking device 2
It is not limited to the anchor-like shape,
Any other shape may be used as long as it has a function of restricting the shape. For example, a hole may be formed in the head, and the hole may be restrained through the linear body 3. When the linear body 3 is restrained by an adhesive, solder, or the like, the linear body 3 may have a bonding surface suitable for these.

According to the first embodiment, the linear member 3
Although a stainless steel wire was used as the material, any other metal wire or a string made of plastic, fiber, or the like may be used as long as it has a strength and a life that can fix the long body 1 over the entire life. . Further, the tape may be in the form of a tape, and various tapes such as metal, plastic, and fiber can be used. For convenience of operation, it is preferable that the linear body 3 can be wound around a drum and handled.

According to the first embodiment, the linear member 3
Are alternately straddled over the surface of the power cable 1 and intermittently restrained by the linear body locking device 2 to thereby obtain the linear body 3, the power cable 1,
Although the method of fixing the power cable 1 to the wall surface 4 using the frictional force between the wall surfaces 4 is adopted, the present invention is not limited to this, and the tape-shaped linear body 3 is parallel to the elongated body 1. A method may be used in which the elongated body 1 is fixed by covering the end from the upper part and restraining the end of the elongated body 1 to the wall surface 4 with the linear body locking tool 2.

(Embodiment 2) In Embodiment 1 described above, 1
Although the case where the power cables 1 are fixed has been described, even when a plurality of long bodies 1 are simultaneously fixed as illustrated in FIG. As long as the strength is within the range of the strength of the linear body 3, the linear body 3 can be fixed using the same linear body locking tool 2 and the same linear body 3 by the same method in principle.

Therefore, according to the method of the present invention, it is possible to prepare a relatively small number of kinds of the linear body locking tools 2 and the linear bodies 3 without preparing many kinds of the linear body locking tools 2 and the linear bodies 3. If you prepare body 3,
It is possible to cope with the case where a wide variety of long bodies are fixed.

(Embodiment 3) In Embodiments 1 and 2 described above, one linear body 3 is stopped by the linear body locking member 2 by alternately straddling the upper part of the power cable 1. Although the method of fixing the cable 1 to the wall surface 4 was adopted, as shown in FIG. 3, the upper part of the long body 1 is straddled so that the two linear bodies 3 are symmetrical, so-called crossover. By fixing the long body 1 to the wall surface 4 by clinging, it is also possible to fix the long body with two sets of the linear body locking tool 2 and the linear body 3.
Thereby, the fixing strength to the wall surface can be improved. Of course, it is also possible to fix the cable 1 to the wall surface by using three or more sets of the linear body locking device 2 and the linear body 3.

As a method of increasing the fixing strength of the elongated body 1, of course, shortening the fixing interval of the linear body locking member 2 to the wall surface 4, and reducing the distance between the linear body locking member 2 and the linear body 3 itself. It is also possible by increasing the strength.

[0029]

The method for fixing a long body to a wall surface according to the present invention is particularly effective when a robot is used, and the work for fixing a long body to a wall surface even in an environment where a human could not work conventionally. It is possible to avoid damage during the life of the long body and to improve the soundness.

Further, the efficiency of the work for fixing the elongated body can be improved. Further, the size of the fixing portion can be made smaller than before, and a relatively large number of long bodies can be laid in a fixed volume, so that the utilization efficiency of the laying space is improved. In addition, unlike the related art, the risk of the elongated body hanging down in the middle of the fixed point is extremely reduced, and when the elongated body needs to be removed, it can be easily removed by cutting the linear body. .
