Description

  The present invention relates to a height adjustment device, and in particular, supports a support such as a shelf or a rail on the floor surface by adjusting the level to a floor surface level or a predetermined height or angle, and height. The present invention relates to a height adjusting device that can be easily replaced without lifting a support such as a rail even when the adjusting device is damaged.

Conventionally, although not particularly limited, for example, in a stacker crane or the like, when the stacker crane is guided to travel in a predetermined traveling path (course) in an automatic warehouse, along the traveling path of the stacker crane Running rails are laid.
However, since the horizontal level of the concrete floor on which the traveling rail is laid is not necessarily constant, the traveling rail is laid at a predetermined height as shown in FIG. 2 in order to maintain the horizontal level of the traveling rail. As described above, a plurality of height adjusting devices (adjusters) are arranged on the floor surface, and these height adjusting devices are used to support the height level of the traveling rail to be constant.

By the way, as a conventional height adjusting device, for example, there is one having a structure as shown in FIG.
This height adjusting device caulks a part of the lower part of the adjuster bolt to the cup-shaped adjuster pad 1 so as to prevent it from coming off, and allows it to be rotated and inserted into the lower part of the adjuster bolt 2, particularly the adjuster pad 1. A rotation adjusting piece 21 having a hexagonal bolt head shape is integrally formed at a position in contact with the adjuster pad 1, and a load applied to the adjuster bolt 2 is supported by the adjuster pad 1. 3, the height of a support such as a rail is adjustable and supported.

  However, when it is used for a long period of time like a running rail, it may be damaged due to an overload applied to the height adjusting device, or a problem of corrosion may occur. Thus, when it becomes impossible to support the load applied to the height adjusting device properly due to breakage or corrosion, it is necessary to replace the height adjusting device with a new one in view of safety.

In such a case, in view of the support structure of the traveling rail using the conventional height adjusting device, in the state where the traveling rail is laid, as shown in FIG. Since the total length cannot be reduced, that is, the height position of the bolt head cannot be lowered, only the damaged or corroded height adjusting device cannot be removed from the lower part of the traveling rail. Accordingly, one end of the traveling rail supported by the height adjusting device is removed, and the damaged or corroded height adjusting device is removed and then replaced with a new one.
Therefore, it takes a lot of time and labor to replace the faulty height adjustment device, and the operation of the stacker crane must be stopped for a long time when the height adjustment device is replaced. There was a problem.

  In view of the problems of the conventional height adjusting device, the present invention is an adjuster bolt that is rotatably inserted into an adjuster pad disposed on the floor surface, and more particularly, an adjuster bolt that protrudes upward from the adjuster pad. The height of the adjuster bolt head is lowered by reducing the overall length of the adjuster, and only the height adjustment device with a malfunction such as breakage is removed while the traveling rail is supported by another height adjustment device. An object of the present invention is to provide a height adjusting device that can be replaced.

  In order to achieve the above object, the height adjusting device of the present invention comprises an adjuster pad and an adjuster bolt which is supported by the adjuster pad so that the lower end of the adjuster pad is prevented from coming off and is rotatable. In the height adjusting device, the lower end portion of the adjuster bolt can be inserted into the adjuster pad so that the length of the adjuster bolt protruding upward from the adjuster pad can be adjusted.

  In this case, the support can be supported at the upper position of the adjuster bolt, and the rotation operation piece for the rotation operation can be formed integrally with the adjuster bolt.

  Further, the adjuster pad is cup-shaped, and the space between the bottom surface and the floor surface of the adjuster bolt to be inserted into the adjuster pad is configured to be larger than the upper end length of the bolt protruding on the rotating operation piece of the adjuster bolt. be able to.

  Further, a height adjusting nut and a fixing nut for adjusting the support height of the support by the adjuster bolt can be screwed into a double nut shape on the side of the adjuster bolt that contacts the adjuster pad.

  According to the height adjusting device of the present invention, the height adjusting device includes an adjuster pad and an adjuster bolt that is supported by the adjuster pad so that the lower end of the adjuster pad is prevented from coming off and is rotatable. The adjuster bolt that protrudes upward from the adjuster pad can be adjusted by adjusting the length of the adjuster bolt that protrudes upward from the adjuster pad by enabling the lower end of the adjuster bolt to be inserted into the adjuster pad. The height adjusting device in which a problem has occurred can be easily and quickly replaced without removing the support supported by another height adjusting device.

  In addition, by supporting the support at the upper position of the adjuster bolt and forming the rotating operation piece for rotating operation integrally with the adjuster bolt, it protrudes above the rotating operation piece even if the height is adjusted. Since the bolt length to be made is always constant, the support can be easily attached.

  Further, the adjuster pad is cup-shaped, and the space between the bottom surface and the floor surface of the adjuster bolt to be inserted into the adjuster pad is configured to be larger than the upper end length of the bolt protruding on the rotating operation piece of the adjuster bolt. Therefore, the upper end of the adjuster bolt can be moved up and down, so the length of the adjuster bolt protruding above the adjuster pad can be easily reduced. This can be done quickly without removing the support.

  In addition, the height adjustment can be adjusted by screwing the height adjustment nut and the fixing nut for adjusting the support height of the support with the adjuster bolt into the double nut shape on the side of the adjuster bolt that contacts the adjuster pad. It can be performed simply, quickly and firmly.

  Embodiments of the height adjusting device of the present invention will be described below with reference to the drawings.

1 to 2 show an embodiment of the height adjusting device of the present invention.
FIG. 1 is a front view of the right half of the height adjusting device A according to the present invention, and shows a cup-shaped adjuster pad 1 disposed on the floor surface F, and a lower end portion of the adjuster pad that is prevented from falling out. An adjuster bolt 2 that can be rotated and inserted by a formula, and a double nut-like height adjusting nut 3 and a fixing nut 4 that are screwed to the adjuster bolt 2.

  The adjuster pad 1 has a deep cup shape and has a strength that can sufficiently support the load applied to the height adjusting device A, and is a bolt for inserting the lower end of the adjuster bolt 2 into the central portion of the top piece 10. The insertion hole 11 is drilled, and the inside of the adjuster pad 1, particularly the lower part of the top piece 10, is hollow, and the depth (space length) of the hollow part 12, that is, the adjuster pad 1 is arranged on the floor surface F. When installed, the space length L1 between the floor surface F and the lower end surface of the adjuster bolt 2 inserted into the adjuster pad 1 projects to the length between the rotating operation piece 21 and the upper end of the bolt, that is, the rotating operation piece. The bolt upper end length L2 is set to be larger.

The adjuster bolt 2 has a predetermined required length and diameter, and after its lower end portion is inserted into the bolt insertion hole 11 of the adjuster pad 1, the end portion is formed with a retaining piece 13 by caulking or the like. In addition, it is pivotably locked and combined with the adjuster pad 1, and a support is provided at an upper position of the adjuster bolt 2, which is not particularly limited, for example, supports the traveling rail R and the like, and A rotation operation piece 21 for rotation operation is formed integrally with the adjuster bolt 2.
When the traveling rail R is supported, the traveling rail R is attached via a rail mounting base B fixed to the upper end of the height adjusting device A, as shown in FIG.
Although this rotation operation piece 21 is not specifically limited, For example, it forms in the shape of the head of a hexagon bolt, other polygons, and manual tools, such as a spanner, can be hung from the outside, So that it can be rotated easily.
In addition, the position where this rotational operation piece 21 is formed is such that the length L2 between the top surface of the rotational operation piece and the upper end of the adjuster bolt is a space between the lower end surface of the adjuster bolt 2 inserted into the adjuster pad and the floor surface F. It is set to be smaller than the length L1. Thus, the overall length of the adjuster bolt that is retracted into the adjuster bolt and protrudes from the adjuster pad can be shortened.

  Further, the adjuster bolt 2 is screwed with a height adjusting nut 3 and a fixing nut 4 in a double nut shape so as to be in contact with the top surface of the top piece 10 of the adjuster pad 1, and thereby, from the top surface of the adjuster pad. By adjusting the length of the protruding adjuster bolt 2, more specifically, the length L 3 from the floor surface F to the top surface of the rotation operation piece 21, a support such as a running rail R supported by the rotation operation piece 21. Adjust the support height.

  When a support such as a running rail R is newly laid and disposed, this height adjusting device fits the top end of the adjuster bolt 2 in a support hole formed on the support in the same manner as before. It arrange | positions so that it may insert. In this case, two nuts having a double nut shape, that is, the height adjusting nut 3 and the fixing nut 4 are loosened. The height adjustment is performed by turning the height adjusting nut 3 in the form of a double nut to adjust the length L3 from the floor surface F to the top surface of the turning operation piece 21. When the predetermined height adjustment is completed, the fixing nut 4 is tightened so as to be in strong contact with the height adjusting nut 3, the height adjusting nut 3 is fixed, and the height adjusting device A is attached.

By the way, when used over a long period of time, the height adjusting device may be damaged or corroded by an overload applied to the height adjusting device A. If such a problem occurs, the load applied to the height adjusting device cannot be properly supported.
Therefore, when a malfunction occurs due to damage or corrosion, it is necessary to replace the damaged or corroded height adjusting device with a new one.
In order to replace the troubled height adjusting device, the fixing nut 4 is first loosened and then the height adjusting nut 3 is loosened while the support such as the traveling rail R is left as it is. This is done by turning the fixing nut 4 or the height adjusting nut 3 by putting a tool such as a spanner on the rotating operation piece 21 fixed to the adjuster bolt 2 and the fixing nut 4 or the height adjusting nut 3 respectively. This can be done easily.

  By rotating the height adjusting nut 3 so as to loosen, the lower end portion of the adjuster bolt 2 is inserted into the cavity portion 12 in the adjuster pad 1, and the adjuster bolt protruding from the top surface of the adjuster pad 1 The length of 2 is shortened. This shortens the length L3 from the floor surface F to the top surface of the rotating operation piece 21. In this case, the lower end portion of the adjuster bolt 2 is inserted into the hollow portion 12 in the adjuster pad 1, but the portion of the length L2 that protrudes substantially above the rotating operation piece 21 of the adjuster bolt 2 is It is absorbed by the space length L1 in the hollow portion 12, and the upper end portion of the adjuster bolt 2 is completely extracted from the support hole of the support.

  In this state, the support of the traveling rail R by the faulty height adjusting device is completely released, and the faulty height adjusting device can be taken out through the space on the lower surface side of the support. In this way, the height adjusting device which has been damaged due to breakage or corrosion is removed, and similarly, the lower end portion of the adjuster bolt 2 is inserted into the hollow portion 12 in the adjuster pad 1 so that the length of the projecting bolt is shorter than that of the adjuster pad 1. After the new height adjusting device is removed and placed at the position of the height adjusting device where the problem occurred, the height is adjusted by rotating the height adjusting nut 3, and then the fixing nut 4 is The replacement of the height adjusting device A is completed by tightening and fixing.

  In addition, although the said Example demonstrated the attachment of the running rail, when using the height adjusting device of this invention for installation of the shelf of an automatic warehouse, a vending machine, etc. (all are not shown in figure), the rotation of the adjuster bolt 2 is carried out. After the bolt portion above the moving operation piece 21 is inserted into a mounting hole (not shown) of a mounting frame (not shown) disposed on the lower portion of a shelf or a vending machine, a fixing nut is screwed into the upper bolt portion. Thus, the mounting frame is clamped by the fixing nut and the rotating operation piece 21 from above and below. The replacement of the height adjusting device A in this case is performed in the same manner as the traveling rail R.

  The height adjusting device of the present invention has been described above based on the embodiments thereof. However, the present invention is not limited to the configurations described in the above embodiments, and the configurations are appropriately set within the scope not departing from the gist thereof. It can be changed.

  The height adjusting device according to the present invention reduces an overall length of an adjuster bolt that is rotatably inserted into an adjuster pad disposed on the floor surface, particularly an adjuster bolt that protrudes upward from the adjuster pad. Since the height position of the head can be lowered, it has the property that only the height adjustment device that caused the problem can be removed and replaced, so it can be used suitably for the purpose of laying the traveling rail of a stacker crane In addition, it can be used for, for example, installation of shelves in automatic warehouses and vending machines.
