Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoisting equipment for carrying out hoisting work required when constructing a curved roof represented by a dome roof, a shell roof, an arch roof, etc. The present invention relates to equipment for lifting a roof base material to be attached to a roof structure such as a structure and a roof finish material to be attached to the roof base material to an installation location.

[0002]

2. Description of the Related Art Conventionally, a mobile crane installed on the ground around the outer periphery of a lower structure has been used for hoisting a roof base material and a roof finishing material to an installation location.

[0003]

However, according to the above-mentioned conventional technique, as a crane to be installed on the ground, a crane having an arm having a length reaching from the ground on the outer periphery of the lower structure to the installation location is required. So if the roof is wide,
A large crane with a very long arm and a large hoisting radius is required to lift the roof substrate and roof finishing material to a central part of the roof, which is separated from the outer periphery of the roof by a large distance.
As a result, hoisting was lacking in speed, and hoisting work required a great deal of time. In other words, the workability of lifting was poor.

Moreover, generally, a large crane having a large hoisting radius has a large hoisting load as well as a large hoisting capacity. On the other hand, the roofing base material and the roof finishing material are relatively lightweight, so that the hoisting load is large. Therefore, a crane having a very excessive performance was used, and the lifting cost was high.

An object of the present invention is to provide a lifting equipment for a curved roof which can lift a roof base material and a roof finishing material to a predetermined portion of a curved roof with good workability and at low cost.

[0006]

According to a first aspect of the present invention as set forth in claim 1, the feature of the lifting equipment for a curved roof is that the structure of the curved roof or the roof foundation attached to the structure is along the roof slope. The lifting rail extending from the lower end to the upper end of the curved roof in a different posture is supported along the contour line of the curved roof so that the position of the lifting rail can be freely changed, and a carriage that can move on the lifting rail is provided. The present invention is provided with a cargo handling device for performing cargo handling between the luggage carrier and an outer portion of the carriage, and a horizontal maintaining means for maintaining the cargo carrier in a horizontal or substantially horizontal posture.

A feature of the lifting equipment for a curved roof according to the second aspect of the present invention is that in the first aspect of the invention, the lifting rail has a plurality of rail bodies that can be connected and separated in the longitudinal direction. It is composed of

[0008]

According to the first aspect of the present invention, the lifting rail extending from the lower end to the upper end of the curved roof in a posture along the roof slope is supported so as to be repositionable along the contour line of the curved roof, and the lifting rail is supported. Since the movable carriage is provided, the carriage can be moved to all positions on the curved roof by moving the carriage on the lifting rail and changing the position of the lifting rail. In other words, the carriage can be moved from any place on the curved roof to any other place.

[0009] Since the cart is provided with a luggage carrier so that luggage such as roof base material and roof finishing material can be transported, it is possible to transport luggage from any place on the curved roof to any other place. .

As a result, the outer periphery of the curved roof is set as a place for receiving luggage from the ground to the trolley, and the received roof base material and roof finishing material are transported to an arbitrary installation place of the curved roof. Therefore, as a crane that is installed on the ground around the outer periphery of the substructure and lifts roof base materials and roof finishing materials, it is sufficient to lift roof base materials and roof finishing materials from the ground to the outer periphery of the curved roof. A small crane with a short arm is sufficient.

Moreover, since the cart is provided with the cargo handling device, it is possible to efficiently and efficiently transfer the roof base material and the roof finishing material from the cargo bed to the installation location.

In addition, since the carriage is provided with the horizontal maintaining means, the carriage can be moved along the curved surface of the roof, but the cargo bed can be maintained in a horizontal posture so that the carriage can be used as a roof base material for various parts of the roof. And roof finishing materials can be safely transported, and it is easy to load roof base materials and roof finishing materials from the ground crane to the loading platform of the truck and to take them out from the loading platform to each installation location by the cargo handling device attached to the truck. It can be done safely and quickly.

According to the second aspect of the invention, since the lifting rail is divided into a plurality of rail bodies, it is necessary to assemble and install the lifting rail required prior to the lifting installation of the roof base material and the roof finishing material. As a work form of the installation of the dolly,
<1> First, one of the rail bodies located on the outer peripheral side of the roof is lifted and supported by a crane installed on the ground, and <2>
Then, set the dolly on the installed rail body,
<3> After that, a crane installed on the ground lifts other rail bodies to the loading platform of the truck and transports them to the roof center side, and the rail bodies that have previously supported the transported rail bodies When the hoisting rail and bogie are installed by adopting a mode in which the hoisting rail is carried into the connecting position by the cargo handling device attached to the bogie and supported, and <4> such steps <3> are repeated to assemble the hoisting rail. No need for a large crane, just a small one to install on the ground.

Of course, when it is necessary to dismantle and remove the lifting rail after the lifting work, and also to remove the carriage,
As the removal work form, the procedure opposite to the installation work form is performed, that is, <1> disconnect the rail body on the center side of the curved roof and transport it to the outer periphery of the curved roof with a trolley, 2> Lower the transported rail body to the ground with a crane installed on the ground, <3> Such <1><2>
By sequentially repeating the procedure of <4>, the rail bodies other than the rail body located on the outer peripheral part are dismantled and removed, and <4> After that, the trolley and the last rail body are unloaded to the ground by the ground crane. A large crane is not required when dismantling and removing the lifting rails and trolleys, and it is only necessary to prepare a small crane to be installed on the ground.

[0015]

According to the first aspect of the present invention, therefore, a crane having a large hoisting load is not required, and it is easy, safe and quick.
Moreover, it has become possible to provide a hoisting equipment for a curved roof capable of hoisting a low-cost and lightweight roof base material and roof finishing material to a predetermined installation location.

In particular, according to the second aspect of the present invention, the lifting rail and the truck can be easily installed using a small crane.
