Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for hoisting and unloading materials from a hoisting opening using a crane at a construction site.

[0002]

2. Description of the Related Art At a construction site of a building, it is necessary to lift necessary materials on each floor. On the contrary, it is necessary to unload unnecessary materials on each floor to the ground. Lifting can be done using a lift at the stage of finishing work, but (a) If there is no lift at the stage of building work, (b) If the dimensions and weight of the material are too large to get on the lift, Use cranes and tow trucks installed on the roof to hoist materials.

At this time, when the unloading stage cannot be provided outside each floor, an unloading opening is provided inside the building to cope with the situation.

[0004]

In the past, the opening was simply opened and the material was hung by a crane to unload the material. However, since the suspended load hung by the crane is simply hanging, there is a risk of colliding with the inner wall surface of the opening because it swings or rotates, and therefore the opening becomes unnecessarily large, It was necessary to attach an attendant.

The present invention has been proposed in view of the above-mentioned problems of the prior art. The object of the present invention is to improve the safety in the case of hoisting and unloading materials using a hoisting opening and to improve automation. The purpose is to provide equipment for lifting and unloading materials.

[0006]

Means for Solving the Problems In order to achieve the above-mentioned object, a device for hoisting and unloading materials according to the present invention has a hoistway formed by penetrating each floor of a structure at the same position on a plane, A pair of left and right guides are installed, and both ends of a luggage suspending member suspended by a lifting machine so as to be movable up and down are fitted to the guides so as to be movable up and down.

According to a second aspect of the present invention, the guide is formed so that it can be divided at each floor, and the upper and lower parts of the divided guide are funnel-shaped. According to a third aspect of the invention, guide rollers are mounted on both ends of the luggage hanging jig.

[0008]

Since the present invention is constructed as described above,
By suspending the luggage via the luggage suspension member, and by stably lifting the luggage suspension jig along the left and right guides installed in the hoistway that penetrates each floor of the structure at the same position on the plane. , There will be no shaking or rotation of the luggage, and there will be no need for an attendant while lifting or lowering the luggage.

According to the invention of claim 2, since the guides can be divided on each floor, the guides can be removed one floor at a time according to the progress of construction, and each split guide is formed in a funnel shape at the top and bottom. Therefore, the hanging jig can be easily inserted into the hoisting guideway. Further, according to the invention of claim 3, since the guide rollers are mounted on both ends of the hoisting jig, the luggage can be smoothly loaded through the hoisting jig along the left and right guides in the hoistway. Can be fried.

[0010]

The present invention will be described below with reference to the illustrated embodiments. A is a structure, which is composed of a large beam b bridged between the pillars a in the X direction, a beam c extending between the large beams b in the Y direction, and a floor d, Floors F ₁ , F ₂ ... F at the same arbitrary planes in the structure A
_The hoistway B extends through _n .

Between the large beams b facing each other in the X direction in the hoistway B, guides 1 each having a groove-shaped cross-section, whose left and right facing surfaces are open, are installed. Is rotatably mounted, and a horizontal load-carrying member 3 slightly shorter than the left and right guides 1 and 1 is vertically movably fitted therein. In the figure, 4 is a bracket for fixing the guide 1 to the girder b, and 5 is a bolt for tightening the guide 1 on the bracket 4.

The guide 1 is constructed by detachably connecting a single guide unit 1a, which has a funnel-shaped upper and lower portion and has an open end from the unloading floor F to the uppermost floor. . In the figure, 1b is a connecting portion of the upper and lower guides 1.
Since the illustrated embodiment is configured as described above, in the hoistway B, the luggage suspension member 3 mounted between the guides 1 on the left and right sides is lowered to the unloading floor F, and the suspension ring of the luggage suspension member 3 is lowered. The material N is suspended from the sling wire 3p on the 3a, and the construction material N is hoisted to the floor where the material is lifted up to the required floor by the lifting machine M such as a crane on the suspension ring 3b via the sled wire q. Unload.

At this time, when the wheels 2 attached to both ends of the luggage suspending member 3 come into contact with the guides, the wheels 2 rotate to reduce friction and smoothly move the member 3 up and down. In FIG.
r is a sling shackle. FIG. 5 shows another embodiment of the guide 1, which is separated into a funnel-shaped guide 1c and a linear guide 1d, and the linear guide 1d is made up of several kinds of members having different lengths so that the height of the building is increased. Adjust the length according to the height of the pod and if the unloading of the intermediate floor is not required, connect only the linear guide and use it as a direct connection.

[0014]

According to the present invention, as described above, the left and right guides installed in the hoistway that penetrates each floor of the building at the same position on the plane, and the load hanging by the lifting machine so that it can be lifted and lowered freely. Fit both ends of the member up and down,
By lifting and lowering the luggage along the guide by the luggage suspending member, the luggage does not shake or rotate, the safety is improved, and an attendant for handling the cargo becomes unnecessary.

According to the second aspect of the present invention, the guides can be divided on each floor, so that the guides can be removed one by one according to the progress of the construction. Further, since the upper and lower sides of the guide are formed in a funnel shape, the guide insertion work of the luggage hanging member can be easily performed. The invention of claim 3 is
Since the guide rollers are mounted on both ends of the luggage suspending member, the luggage can be smoothly moved up and down along the guides.
