Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hanging tool such as a steel plate.In a suction type lifting tool for lifting a steel plate, etc., a suction pad to be used is selected from a plurality of suction pads having a function of descending when in use, and only the suction pad to be used is lowered. It relates to a hanging tool such as a steel plate that is designed to land on a suspended load.

[0002]

[Prior art]

 Generally, as a suspending tool such as a steel plate or a concrete block, a handing method is performed by using a suspending tool having a plurality of suction pads formed of a circular or elliptic rubber-like elastic body. A plurality of suction pads are arranged to hang lifting equipment of various sizes, and it is common to select the suction pad to be used according to the size of the load.

The arrangement of the suction pads includes a beam type as shown in FIG. 3 and a bogie type as shown in FIG.

As shown in FIGS. 3 and 4, the suction method is such that the suspending tool is hung by the hook 2 of the ceiling crane in the building, and the suction pad 3 ′ used is hung so as to land on the suspended load 4. Lower the tool and select the pad 3'to be sucked according to the size of the hanging load 4, and suck the hanging load 4. After the suction is completed, the suspended load 4 that has been adsorbed is hoisted by hoisting the hoisting device with a ceiling crane (not shown). The pad 3 may be damaged and may be damaged.

Further, as shown in FIG. 4, when the upper suspended load 4 of the suspended load having two plates stacked is suspended, the unused suction pad 3 comes into contact with the lower suspended load 4 ′, so that the vacuum piping is Even if the pad is opened to the atmosphere, the air is not filled in the pad for several seconds when the hoist is lifted to be in a vacuum state, and the unused suction pad 3 is in a suction state. As a result, the lower load 4'is lifted up, and as the unused suction pad 3 is filled with the atmosphere, the suction force of the pad weakens and then falls.

As described above, in the suction-type hanging device having the conventional structure, the unused suction pad 3 comes into contact with the soil when sucking the steel plate or the like, and the unused suction pad 3 is damaged. When the pulling pad 3 comes into contact with something other than the suspended load, the pulling pad 3 becomes in a suction state, and after lifting, there is a problem that it falls.

Further, Japanese Utility Model Laid-Open No. 49-660 discloses an article suction device including a plurality of units each including a suction plate and a suction cylinder via a ball joint. -Sheet depaling method, etc., in which some suction devices are moved up and down relative to other suction devices at the initial stage of lifting the seat, and the seat is lifted while giving elastic bending to the seat. However, all of these give a relative movement to the adsorption device in the suctioned state, and are not used to select an unused adsorption device and do not solve the above-mentioned problems of the prior art.

[0008]

[Problems to be solved by the device]

 The present invention is intended to solve the above-mentioned problems, and specifically, it has a function of lowering each suction pad when using a hanging tool such as a steel plate, and depending on the size of the steel plate to be sucked. While selecting the suction pad to be used and lowering and sucking this pad, at the time of sucking the steel plate, by separating the unused suction pad from the steel plate other than the steel plate to be sucked or the soil, the steel plate other than the steel plate to be sucked The purpose of the invention is to propose a suspender such as a steel plate that prevents the suction of air.

[0009]

[Means for Solving the Problems]

 That is, the present invention is used in a suction-type suspender that is provided with a plurality of suction pads made of a rubber-like elastic body having a circular shape or an elliptical shape, and the inside of the suction pads is vacuumed to suck a steel plate or the like and lift it. Select the suction pad to be used according to the size of the steel plate to be sucked among the suction pads that have the function of lowering by the cylinder etc., and lower the suction pad to be used and suck, while suction the unused suction pad It is characterized in that it is configured to be separated from steel plates other than the steel plate to be formed.

According to the present invention, it is possible to prevent suction of a steel plate or the like other than the steel plate to be sucked and / or to prevent damage to an unused suction pad.

Hereinafter, the structure and operation of the means of the present invention will be described.

[0012]

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a schematic diagram when the present invention is applied to a beam type suction-type hanging device, and FIG. 2 is a schematic diagram when the present invention is applied to a bogie-type suction-type hanging device. Is.

First, as shown in the left diagram of FIG. 1, the suction pad 3 of FIG. 1 is lifted into the suction-type hanging device main beam 1 by a spring 6 for lifting the suction pad when not in use. At this time, the suction pad 3'is selected and used to operate the suction pad lowering air-cylinder-5, pushing down the metal fitting end of the suction pad 3'and lowering the suction pad 3 '. Therefore, the suction pad 3'used when the suspender lands on the suspended load 4 such as a steel plate comes into contact with the suspended load 4, but the unused suction pad 3 is suspended on the soil or another steel plate 4 '. Do not touch.

Further, as shown in FIG. 2, the suction pad 3 ′ to be used is selected and used, and each descending air-cylinder 5 under the suction pad is actuated, and the small beam 7 of the bogie-type lifting device is operated. The suction pad 3'used to push down or pull up one end of the one lowers.

[0016]

As described in detail above, according to the present invention, a plurality of suction pads made of a rubber-like elastic body having a circular shape or an elliptic shape are arranged, and a vacuum is applied to the inside of the pad to remove a steel plate or the like. In the suction-type lifting device that sucks and lifts, the suction pad to be used is selected according to the size of the steel plate, etc. that is sucked and lifted in the suction pad that has the function of lowering with a cylinder etc. during use. It is characterized in that it is configured to lower the suction pad to suck the steel plate and the like while separating the unused suction pad from the steel plate and the like other than the steel plate to be sucked.

In the present invention, only the suction pad to be used among the plurality of suction pads of the suction type lifting device is lowered, so that the unused suction pad is prevented from coming into contact with the soil and the suction pad is not damaged. I was able to. Moreover, since it does not come into contact with other suspended loads such as steel plates of the unused suction pad, there is no risk of lifting other suspended loads.
