Description

An embodiment of the present invention relates to a piping support device.

Piping in plants and the like is supported by a pipe support device in consideration of earthquake resistance, etc. The pipe support device restrains and protects the pipe so that it is not damaged even when mechanical loads such as the weight of the pipe, thermal displacement, and earthquake inertia force act on the pipe.

However, when the mechanical load is large, if the pipe is tightly restrained, excessive stress will be generated in the pipe as the pipe moves and expands/contracts, and the pipe may be damaged. In particular, when the pipe and the pipe support device are welded, there is a risk that the welded part will break and damage the pipe, which may cause the internal fluid to leak. Therefore, when stress exceeding a predetermined value is generated in the pipe, it is considered to prevent the pipe from being damaged by releasing the restraint of the pipe.

First Embodiment
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment will be described with reference to the drawings. Fig. 1 is a schematic side view of a pipe support device according to the first embodiment.

As shown in Fig. 1, the pipe support device 1 according to this embodiment includes a first pipe support 10, a second pipe support 11, a base 12, and a stopper 13. The pipe support device 1 supports a pipe 2 from below. The second pipe support 11 is disposed below the first pipe support 10.

The first pipe support 10 is fixed to the pipe 2 above, and the lower end of the first pipe support 10 is machined into a concave shape. The upper end of the second pipe support 11 below the first pipe support 10 is machined into a convex shape so as to fit into the lower end of the first pipe support 10. The first pipe support 10 and the second pipe support 11 fit into each other with their respective concave and convex parts.

The second pipe support 11 is supported by a base 12. The stopper 13 is arranged in a direction x between the first pipe support 10, the second pipe support 11, and the base 12, which is parallel to the pipe 2.
The stoppers 13 are provided adjacent to each other in the direction of the arrow of the axis (hereinafter referred to as the x-axis direction), and the height of the stoppers 13 is higher than the base 12 and lower than the lower end of the convex portion of the second piping support 11. In other words, the movement of the second piping support 11 in the x-axis direction is restricted, but the movement of the first piping support 10 in the x-axis direction is not restricted.

At this time, the pipe 2 and the first pipe support 10 are fixed with a band or the like (not shown).
The pipe support 10 and the second pipe support 11 are not bonded with an adhesive or the like.
The pipe support 11 and the base 12 are not bonded with adhesive or the like.
The pipe support 10 and the second pipe support 11 can each be easily replaced.

The stopper 13 is provided with a movement detector 3. The movement detector 3 is connected to a receiver 4 arranged outside the system, for example, via a network, and transmits a signal indicating that the movement detector 3 has detected movement to the receiver 4. The receiver 4 detects the movement of the movement detector 3 based on the received signal.
The system notifies workers, etc. that it has detected movement.

The fitting between the first pipe support 10 and the second pipe support 11 may have a gap corresponding to the allowable movement distance of the pipe 2. Also, a material that deforms by the allowable movement distance of the pipe 2 may be used.

In addition, the concave and convex portions of the first pipe support 10 and the second pipe support 11 may have opposite shapes, as long as the first pipe support 10 and the second pipe support 11 can be fitted together.

Next, the operation of the pipe support device 1 will be described when a load in the x-axis direction due to thermal displacement or the like acts on the pipe 2.

When a load in the x-axis direction due to thermal displacement or the like acts on the pipe 2, the pipe 2 and the first pipe support 10 fixed to the pipe 2 attempt to move in the x-axis direction. At this time, the engagement between the first pipe support 10 and the second pipe support 11 causes the second pipe support 11 to act as a restraining member and restrain the movement of the pipe 2 and the first pipe support 10. In addition, the movement of the second pipe support 11 on the base 12 causes the pipe 2, the first pipe support 10, and the second pipe support 11 to move in the x-axis direction.
When both of them try to move in the x-axis direction, the stopper 13 restrains the movement.

When the movement of the pipe 2 and the first pipe support 10 is restrained, stress is applied to the recessed portion of the first pipe support 10 and the protruding portion of the second pipe support 11. When a predetermined amount of stress is applied, the protruding portion of the second pipe support 11 breaks in preference to other portions such as the recessed portion of the first pipe support 10 and the pipe 2, thereby releasing the restraint on the pipe 2 and the first pipe support 10.

The pipe 2 and the first pipe support 10, which have been released from the restraint, move in the x-axis direction in which the load acts, and the movement detector 3 detects the movement. The movement detector 3 transmits a signal to a receiver 4 disposed outside the system, and the receiver 4 detects the movement of the pipe 2 and the first pipe support 10 based on the received signal.
Inform workers that they have been released from their restraints.

With this configuration, it is possible to restrain movement of the pipe 2 in the x-axis direction when a load in the x-axis direction due to thermal displacement or the like acts on the pipe 2. Furthermore, when a predetermined stress or more is applied, the convex portion of the second pipe support 11 breaks in preference to other portions such as the concave portion of the first pipe support 10 and the pipe 2, and the restraint of the pipe 2 and the first pipe support 10 is released, thereby preventing a large stress from being applied to the pipe 2 and preventing damage to the pipe 2.

In addition, the piping 2 and first piping support 10 that have been released from the constraint move, and the movement detector 3 and the receiver 4 arranged outside the system detect and report this movement, thereby notifying workers, etc. that the constraints have been released, so that the broken second piping support 11 can be replaced and restored early.

In this embodiment, a configuration has been described assuming that a load acts in the x-axis direction. However, when a load acts in the direction opposite to the direction of the x-axis arrow in FIG. 1, for example, the same configuration may be provided symmetrically, or a configuration suitable for the direction in which the load acts may be used.

In addition, the point that will break when a certain level of stress is applied may be a recessed portion of the first piping support 10, or it may be a portion other than the recessed portion of the first piping support 10 or a notch or the like may be formed in the main body of the second piping support 11 and the breakage may be caused to occur at a portion other than the protrusion of the second piping support 11.

The movement detector 3 may be, for example, a limit switch, a contact sensor, an infrared sensor, or the like, as long as it can detect the movement of the pipe 2 and the first pipe support 10.

In addition, the movement detector 3 and the receiver 4 arranged outside the system may be configured to collect various data about the surroundings of the pipe support device 1, such as the acting load, the surrounding heat, and the strength of stress.
Such a configuration can be used as a reference when improving the installation position of the piping support device 1 and the design of the piping support device 1, etc.

Second Embodiment
The second embodiment will be described with reference to Fig. 2. Fig. 2 is a schematic side view of a pipe support device according to the second embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. The main difference between this embodiment and the first embodiment is the configuration of the pipe support device 1.

As shown in FIG. 2, the pipe support device 1 according to the present embodiment includes a first pipe support 20 and a second pipe support 21 disposed below the first pipe support 20. The lower end of the first pipe support 20 includes a slope that slopes upward with respect to the x-axis direction, and the first pipe support 20 of the second pipe support 21 is disposed below the first pipe support 20.
The upper end of the first pipe support 20 facing the first pipe support 20 has a slope that slopes upward in the x-axis direction.
The first pipe support 20 and the second pipe support 21 are configured so that their inclined surfaces come into contact with each other. At this time, the first pipe support 20 and the second pipe support 21 are not bonded with an adhesive or the like.

Next, the operation of the pipe support device 1 will be described when a load in the x-axis direction due to thermal displacement or the like acts on the pipe 2.

When a load in the x-axis direction due to thermal displacement or the like acts on the pipe 2, the pipe 2 and the first pipe support 20 fixed to the pipe 2 attempt to move in the x-axis direction. At this time, the second pipe support 21 acts as a restraining member to restrain the movement of the pipe 2 and the first pipe support 20 due to the inclined surfaces of the first pipe support 20 and the second pipe support 21.

When the second pipe support 21 restricts the movement of the pipe 2 and the first pipe support 20,
Stress is applied to the inclined surfaces of the first pipe support 20 and the second pipe support 21. When a predetermined stress or more is applied, the inclined surface of the first pipe support 20 is inclined toward the inclined surface of the second pipe support 21.
The constraint is released as the pipe 2 and the first pipe support 20 slide along the inclined surface, and the pipe 2 and the first pipe support 20 move in the x-axis direction.

The pipe 2 and the first pipe support 20, which have been released from the restraint, move in the x-axis direction in which the load acts, and the movement detector 3 detects the movement. The movement detector 3 transmits a signal to a receiver 4 disposed outside the system, and the receiver 4 detects the movement of the pipe 2 and the first pipe support 20 based on the received signal.
Inform workers that they have been released from their restraints.

With this configuration, when a load in the x-axis direction due to thermal displacement or the like acts on the pipe 2, the movement of the pipe 2 in the x-axis direction can be restrained. Furthermore, when a predetermined stress or more is applied, the inclined surface of the first pipe support 20 slides along the inclined surface of the second pipe support 21 to release the restraint, thereby preventing a large stress from being applied to the pipe 2, and the pipe 2 can be moved.
can be prevented from being damaged.

In addition, the piping 2 and first piping support 20 that have been released from the constraint move, and the movement detector 3 and the receiver 4 arranged outside the system detect and report the movement, thereby notifying workers, etc. that the constraints have been released, so that the moved piping 2 and first piping support 20 can be restored to their original position early.

In this embodiment, a configuration has been described assuming that a load acts in the x-axis direction. However, when a load acts in the direction opposite to the direction of the x-axis arrow in FIG. 2, for example, the same configuration may be provided symmetrically, or a configuration suitable for the direction in which the load acts may be used.

The movement detector 3 may be, for example, a limit switch, a contact sensor, an infrared sensor, or the like, as long as it can detect the movement of the pipe 2 and the first pipe support 20.

In addition, the movement detector 3 and the receiver 4 arranged outside the system may be configured to collect various data about the surroundings of the pipe support device 1, such as the acting load, the surrounding heat, and the strength of stress.
Such a configuration can be used as a reference when improving the installation position of the piping support device 1 and the design of the piping support device 1, etc.

Third Embodiment
The third embodiment will be described with reference to Fig. 3. Fig. 3 is a schematic side view of a pipe support device according to the third embodiment. The same parts as those in the first embodiment are given the same reference numerals, and detailed description will be omitted. The main difference between this embodiment and the first embodiment is the configuration of the pipe support device 1.

As shown in Figure 3, the pipe support device 1 of this embodiment is composed of a first pipe support 30, a second pipe support 31 arranged below it, a connecting member 32, a base 12, and a stopper 13.

The lower end of the first piping support 30 and the upper end of the second piping support 31 are machined into a concave shape, and the concave portions are in contact with each other. The connecting member 32 is provided in a space formed by the respective concave portions of the first piping support 30 and the second piping support 31. At this time, the connecting member 32 is longer than the concave portion of the second piping support 31, and a part of the connecting member 32 is exposed on the concave side of the first piping support 30. In addition, the first piping support 30, the second piping support 31, and the connecting member 32 are not bonded with an adhesive or the like.

Note that a gap may be provided around the connecting member 32 provided in the space formed by the recesses of the first pipe support 30 and the second pipe support 31, the gap being equal to the allowable movement distance of the pipe 2. Furthermore, the connecting member 32 may be made of a material that deforms by the allowable movement distance of the pipe 2.

Next, the operation of the pipe support device 1 will be described when a load in the x-axis direction due to thermal displacement or the like acts on the pipe 2.

When a load such as thermal displacement acts on the pipe 2 in the x-axis direction, the pipe 2 and the first pipe support 30 fixed to the pipe 2 attempt to move in the x-axis direction. At this time, the connecting member 32 provided between the first pipe support 30 and the second pipe support 31 acts as a restraining member to hold the pipe 2 in place.
The second pipe support 31 is fixed to the base 12.
When the pipe 2, the first pipe support 30, and the second pipe support 31 all attempt to move in the x-axis direction due to the movement upward, the stopper 13 restrains the movement.

When the movement of the pipe 2 and the first pipe support 30 is restrained, stress is applied to the connecting member 32. When a predetermined stress or more is applied, the connecting member 32 breaks in preference to other parts such as the recesses of the first pipe support 30 and the second pipe support 31 and the pipe 2, and releases the restraint on the pipe 2 and the first pipe support 30.

The pipe 2 and the first pipe support 30, which have been released from the restraint, move in the x-axis direction in which the load acts, and the movement detector 3 detects the movement. The movement detector 3 transmits a signal to a receiver 4 disposed outside the system, and the receiver 4 detects the movement of the pipe 2 and the first pipe support 30 based on the received signal.
Inform workers that they have been released from their restraints.

With this configuration, it is possible to restrain the movement of the pipe 2 in the x-axis direction when a load in the x-axis direction, such as thermal displacement, acts on the pipe 2. Furthermore, when a stress of a predetermined magnitude or more is applied, the connecting member 32 breaks in preference to other portions such as the recesses of the first pipe support 30 and the second pipe support 31 and the pipe 2, and the pipe 2 and the first pipe support 31 are prevented from moving in the x-axis direction.
By releasing the constraint of 0, it is possible to prevent a large stress from being applied to the pipe 2, and therefore it is possible to prevent the pipe 2 from being damaged.

In addition, the piping 2 and first piping support 30 that have been released from the constraint move, and the movement detector 3 and the receiver 4 arranged outside the system detect and report this movement, thereby notifying workers, etc. that the constraints have been released, so that the broken connecting member 32 can be replaced and restored early.

In this embodiment, a configuration has been described assuming that a load acts in the x-axis direction. However, when a load acts in the direction opposite to the direction of the x-axis arrow in FIG. 3, for example, the same configuration may be provided symmetrically, or a configuration suitable for the direction in which the load acts may be used.

The movement detector 3 may be, for example, a limit switch, a contact sensor, an infrared sensor, etc., as long as it can detect the movement of the pipe 2 and the first pipe support 30.

In addition, the movement detector 3 and the receiver 4 arranged outside the system may be configured to collect various data about the surroundings of the pipe support device 1, such as the acting load, the surrounding heat, and the strength of stress.
Such a configuration can be used as a reference when improving the installation position of the piping support device 1 and the design of the piping support device 1, etc.

Fourth Embodiment
The fourth embodiment will be described with reference to Fig. 4 and Fig. 5. Fig. 4 is a schematic side view of the pipe support device according to the fourth embodiment, and Fig. 5 is a schematic front view of the pipe support device according to the fourth embodiment. The same parts as those in the first embodiment are given the same reference numerals, and detailed description will be omitted. The main difference between this embodiment and the first embodiment is the configuration of the pipe support device 1.

As shown in Fig. 4, the pipe support device 1 according to this embodiment is composed of a first pipe support 40 having a hole formed on its side, a second pipe support 41 located to the side of the first pipe support 40 and having a hole formed on its side, and a connecting member 42 penetrating the hole. Here, the shape and size of the holes formed in the first pipe support 40 and the second pipe support 41 are such that the connecting member 42 can penetrate through them. The first pipe support 40 is formed with a protrusion 40a extending in the direction of the y-axis arrow. This protrusion is configured not to interfere with the second pipe support 41. The second pipe support 41 is configured to restrict the movement of the pipe 2 and the first pipe support 40 in the y-axis direction, and to move in the direction of the x-axis arrow or in the opposite direction to the direction of the x-axis arrow. At this time, the first pipe support 40, the second pipe support 41, and the first pipe support 40 are formed with a protrusion 40a extending in the direction of the y-axis arrow.
The pipe support 41 and the connecting member 42 are not bonded with adhesive or the like.

The holes of the first pipe support 40 and the second pipe support 41 and the connecting member 42
There may be a gap between them that corresponds to the allowable movement distance of the pipe 2. Also, the connecting member 42 may be made of a material that deforms by the allowable movement distance of the pipe 2.

Next, the operation of the pipe support device 1 will be described when a load in the x-axis direction due to thermal displacement or the like acts on the pipe 2.

When a load such as thermal displacement acts on the pipe 2 in the x-axis direction, the pipe 2 and the first pipe support 40 fixed to the pipe 2 tend to move in the x-axis direction. At this time, the connecting member 42 provided in the holes of the first pipe support 40 and the second pipe support 41 acts as a restraining member to prevent the pipe 2 from moving in the x-axis direction.
And the movement of the first piping support 40 is restrained.

When the movement of the pipe 2 and the pipe support 40 is restrained, stress is applied to the connecting member 42. When a predetermined amount of stress or more is applied, the connecting member 42 breaks in preference to other parts such as the first pipe support 40, the second pipe support 41, and the pipe 2, and releases the restraint on the pipe 2 and the first pipe support 40.

The released piping 2 and first piping support 40 move in the x-axis direction in which the load acts, and the protrusion 40a presses the movement detector 3, which detects the movement. The movement detector 3 transmits a signal to a receiver 4 arranged outside the system, and based on the received signal, the receiver 4 notifies an operator or the like that the restraint on the piping 2 and first piping support 40 has been released.

With this configuration, it is possible to restrain movement of the pipe 2 in the x-axis direction when a load in the x-axis direction due to thermal displacement or the like acts on the pipe 2. Furthermore, when a predetermined stress or more is applied, the connecting member 42 breaks in preference to other parts such as the first pipe support 40, the second pipe support 41, and the pipe 2, and by releasing the restraint of the pipe 2 and the first pipe support 40, it is possible to prevent a large stress from being applied to the pipe 2 and to prevent damage to the pipe 2.

In addition, the piping 2 and first piping support 40 that have been released from the constraint move, and the movement detector 3 and the receiver 4 arranged outside the system detect and report this movement, thereby notifying workers, etc. that the constraints have been released, so that the broken connecting member 42 can be replaced and restored early.

In this embodiment, a configuration has been described assuming that a load acts in the x-axis direction. However, when a load acts in the direction opposite to the direction of the x-axis arrow in FIG. 4, for example, the same configuration may be provided symmetrically, or a configuration suitable for the direction in which the load acts may be used.

The movement detector 3 may be, for example, a limit switch, a contact sensor, an infrared sensor, etc., as long as it can detect the movement of the pipe 2 and the first pipe support 40.

In addition, the movement detector 3 and the receiver 4 arranged outside the system may be configured to collect various data about the surroundings of the pipe support device 1, such as the acting load, the surrounding heat, and the strength of stress.
Such a configuration can be used as a reference when improving the installation position of the piping support device 1 and the design of the piping support device 1, etc.

According to at least one embodiment of the pipe support device described above, the axial movement of the pipe is restrained when a load is applied to the pipe, and the restraint is released when a predetermined level of stress is applied, thereby preventing large stress from being applied to the pipe and preventing damage to the pipe.

In addition, a movement detector detects that the pipe has moved, and a receiver notifies workers, etc., so that the released pipe and pipe support device can be quickly restored.

Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
