Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is a load supporting device in which a supported object such as a mechanical device or a building is placed on top and supported by a spring force on a base such as a floor. It relates to an improvement of the device.

(Prior Art) An example of a conventional vertical support type load support device is shown in FIG. In FIG. 3, a cylindrical case 1 has a pair of parallel support plates 3 on the outside of a lid 2 on one end side, and the other end side is fixed to a support S such as a structure with its axis lined vertically. ing.

A coil-shaped compression spring 4 is housed in the case 1 with its axis aligned with the one, and one end of the coil-shaped compression spring 4 is locked to the lid 2 of the case 1.

The pulling rod member 5 is composed of two rods 5a and 5b pivotally supported by a pin 6 at an intermediate portion.
The pulling rod member 5 freely penetrates the lid 2 and has one end side inserted into the case 1, and a spring bearing flange 7 fixed to one end is locked to the other end of the spring 4.

The rotating arm 8 has an intermediate portion pivotally supported by the support plate 3 by a pin 9, one end pivotally supported by one end of the pulling rod member 5 by a pin 10, and the other end pivotally supported by a pin 12 at one end of a support rod 11.
Is pivotally attached to.

The other end side of the support rod 11 is connected to a supported body A such as a piping system and receives a load in the vertical direction of the supported body A.

Thus, this load supporting device is connected to the supported body A in a state in which the spring 4 is compressed in advance by a predetermined amount, and always maintains a predetermined initial load regardless of the amount of vertical displacement of the supported body A. The supported body A is supported.

(Problem to be Solved by the Invention) In the above-described conventional load supporting device, when the supported body A is displaced in the vertical direction, the rotating arm 8 is rotated about the pin 9 via the supporting rod 11. Forced to move in the horizontal direction. As a result, for example, when vibration is applied in the vertical direction, a component force is generated in the horizontal direction, and there is a problem that the support of the supported object becomes extremely unstable due to the overturning moment.

Therefore, the present invention provides a vertically supported load supporting device that does not force the supported body A to be displaced in the horizontal direction even when the rotating arm rotates when the supported body A is displaced in the vertical direction. That is the issue.

(Means for Solving the Problems) In the present invention, in order to solve the above problems, a cylindrical case 21 whose lower end is fixed to the base B with its axis lined in the vertical direction, and a cylindrical case 21 mounted outside the case Guide member
22 is slidably engaged in the vertical direction and is supported on the upper surface of the supported body A.
A support frame 23 for horizontally supporting the case 21, a compression spring 24 housed in the case 21 with its axis aligned, and an upper end locked to a lid 25 of the case 21, and a lower end in the case 21 having a spring 24.
Of the pull rod 26, which is locked to the lower end of the pull rod 26, the upper end of which extends through the lid 25 of the case 21 and projects to the outside of the case 21, and one end of which is pivotally supported by the upper end of the pull rod member 26 and whose middle portion is the case 21. A vertical load supporting device is configured by including a lever 31 pivotally supported by a lid 25 of the above and a supporting rod 34 having an upper end pivotally supported at the other end side of the lever 31 and a lower end pivotally supported by a support frame 23. did.

(Operation) In the load supporting apparatus of the present invention, when the supported body A is displaced in the vertical direction, the support frame 23 is guided by the guide member 22 to be displaced vertically, and the support rod 34 moves up and down together therewith. At this time, the vertical movement of the support rod 34 causes the lever 31 to rotate about the pin 33. The rotation of the lever 31 causes the pulling rod member 26 to move up and down to compress or release the spring 24. During this time, the support frame 23 functions to slightly change the reaction force according to the bending of the spring 24 to push up and support the supported body A, and restore the supported body A to a predetermined original position. The support frame 23 does not move horizontally due to the vertical movement of the supported body A.

(Embodiment) One embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of the load supporting device, and FIG. 2 is a plan view in which a part of the load supporting device is cut away.

In FIG. 1 and FIG. 2, the load supporting device is for horizontally supporting the supported body A on a horizontal base B,
It is provided between the base B and the supported body A.

That is, the lower end of the cylindrical case 21 is fixed on the base B with its axis oriented vertically. A pair of guide members 22 are attached at opposing positions on the outside of the case 21.

A support frame 23 is engaged with the guide member 22 so as to be vertically slidable. That is, the support frame 23 is made of steel material assembled in a gate shape, and the supported body A can be horizontally supported on the upper part of the horizontal beam 23a. The pair of columns 23b of the support frame 23 are vertically erected close to the outside of the case 21, and a slide rail 23c extending vertically inside the case 21 slides vertically on the guide member 22. It is freely engaged.

A coil-shaped compression spring 24 is accommodated in the case 1 with its axis aligned with this, and its upper end is locked by an annular lid 25 at the upper end of the case 21.

The pull rod 26 is composed of a rod 27, a connecting member 28, and a link 29, and is pivotally attached to each other in order from below. And the spring tray fixed to the lower end of the rod 27
30 is locked to the lower end of the spring 24. A pair of left and right links 29 are pivotally attached to the connecting member 28, the upper portions of the links 29 freely pass through the lid 25, and the upper ends of the links 29 are pivotally attached to one end side of the lever 31 by a pin 32.

The lever 31 has a pin 3
While being pivotally supported by 3, the other end is pivotally attached to the upper end of the support rod 34 by a pin 35.

The support rod 34 is configured so that its length can be adjusted, and its lower end is pivotally attached to the column 23b by a pin 36 via a bracket 23d.

Then, the load supporting device is installed so that the upper part is fitted into the box-shaped member C fixed to the lower part of the supported body A such as a mechanical device, and the supported body A is inserted through the member C. It is supported on the support frame 23. Thus, this load supporting device is installed with the spring 24 compressed in advance by a predetermined amount. Then, the spring 24 accompanying the vertical displacement of the supported body A
Supported body A while slightly changing the reaction force with respect to the bending of
And acts to return the supported body A to a predetermined initial setting position. That is, when the supported body A is vertically displaced, the support frame 23 is vertically displaced accordingly. At this time, since the rail 23c is guided by the guide member 22,
The support frame 23 moves up and down together with the support rod 32 while maintaining the vertical state. As the support rod 34 moves up and down, the lever 31 rotates around the pin 33, and the pulling rod member 26 moves up and down via the pin 32 to compress or release the spring 24. During this time, the support frame 23
Supports and pushes up the supported body A.

The present invention is not limited to the illustrated embodiment, and various modifications can be made. For example, the load may be supported by only one support rod 34.

(Effects of the Invention) As described above, in the present invention, the lower end is perpendicular to the cylindrical case 21 fixed to the base B with the axis oriented vertically, and the guide member 22 attached to the outside of the case 21. A support frame 23, which is slidably engaged in the direction and horizontally supports the supported body A, is housed in the case 21 with its axis aligned, and the upper end is locked to the lid 25 of the case 21. Compression spring 24, a lower end of the spring inside the case 21 is locked to the lower end of the spring 24, and an upper end of the pull rod 26 penetrates the lid 25 of the case 21 and projects to the outside of the case 21, and the pull rod member. One end is pivotally supported on the upper end of 26, and the middle part is the lid of case 21.
A lever 31 pivotally supported by 25, and a support rod whose upper end is pivotally supported by the other end of the lever 31 and whose lower end is pivotally supported by the support frame 23.
Since the vertical load supporting device is configured by including 34 and 34, the supporting frame 23 does not rotate even if the lever 31 rotates when the supported body A is displaced in the vertical direction. It is possible to provide a vertical load bearing device that does not force A to be displaced in the horizontal direction.
