Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevating device such as an elevating body consisting of a parking pallet on which a car is parked.

[Conventional technology]

Conventionally, the applicant of the present invention has provided a device described in Japanese Utility Model Application Publication No. 167153/1983 as this type of elevating device for elevating objects.

In this device, the lower end is connected to a chain adjuster provided on the elevating body, and an idler roller provided at the tip of a bracket having a long hole facing the direction of the hoisting sprocket comes into contact with the release side of the hoisting chain of the hoisting sprocket. The bracket is fixed to the mounting part through its elongated hole with a bolt, the lower end of the bolt projects below the mounting, and the tip of the hoisting chain is fixed to the lower end protrusion. .

[Problem that the invention attempts to solve]

Although the above-mentioned conventional device also has the effect of preventing the chain from coming off the hoisting sprocket when the elevating object is raised or lowered, the present invention further improves the reliability and allows the hoisted chain to tightly mesh with the hoisting sprocket, so that the chain is not disengaged from the hoisting sprocket when the lifting body is raised or lowered. It is characterized in that it is constructed so that it does not come off smoothly and does not get caught up in it, and furthermore, it is easy to horizontally install the elevating body and the like and to make subsequent adjustments.

In other words, conventional idler rollers can literally rotate in reverse, holding the chain at a "point", and if a large force is applied from the chain in the direction of release, it may not be possible to prevent the chain from flowing backwards. In order to naturally rotate in the same direction as the chain and to prevent backflow of the chain, if the chain is placed under pressure,
The hoisted chain meshed tightly with the hoisting sprocket, and could not be removed smoothly at the release section, leading to the possibility of the chain becoming entangled.

The winding of the chain is extremely dangerous, as it becomes entangled with the hoisting sprocket, and furthermore, the hoisting chain is cut, and as a result of the cutting, the elevating body, etc. falls, is damaged, and workers are injured.

The present invention effectively prevents the above-mentioned entrainment, furthermore, allows easy horizontal installation and subsequent adjustment, and allows for a smaller chain hoisting section.

[Means for solving problems]

This invention In order to solve the above problems, the lower end is connected to a chain adjuster provided on the elevating body, etc.
On the release side of the hoisting chain that is suspended from the hoisting sprocket provided at the upper part of the hoisting sprocket, there is provided a retaining vertical plate located at the longitudinal center of the hoisting chain that has been hoisted through a mounting plate. The lower hoisting chain releasing portion is provided with a roll-in prevention plate via an arm provided from the lower end of the above-mentioned detachment preventing vertical plate so as to avoid the hanging position of the hoisting chain.

[Effect]

In the present invention, the lower end of the hoisting chain 4 is the lifting body a.
The hoisting sprocket 6 is connected to the chain adjuster 17 provided at 4 is provided with a retaining vertical plate 11 located at the center in the vertical direction.

As a result, the vertical plate 11 prevents the hoisting chain 4 from coming off.

Furthermore, the hoisting chain 4 is connected to the above-mentioned detachment preventing vertical plate 1.
1 and the entrainment prevention plate 14, and its tip is fixed to the lower end of the vertical plate 11 with a set screw 16. As a result, the entrainment prevention plate 14 is positioned at the open portion of the hoisting chain 4 below the hoisting sprocket 6, thereby preventing entrainment during winding.

As described above, according to the present invention, the hoisting chain 4 is prevented from coming off and being rolled up, so the hoisting sprocket 6 can be made small in diameter, and the device can be downsized.

That is, if the hoisting sprocket 6 is made larger in diameter, the area of contact and engagement with the hoisting chain 4 will inevitably become larger, reducing the possibility of it coming off or even getting caught. Since the chain 4 can be effectively prevented from coming off and being rolled up, a winding sprocket with a small diameter can be used and the device can be downsized.

Furthermore, according to the present invention, the chain adjuster 1
7, it is easy to horizontally install the elevating body a and to make subsequent adjustments such as elongation of the hoisting chain 4 due to continued use.
