Description

[Detailed description of the invention] [Industrial application field 1 The present invention relates to a loading/unloading device for a lift.

[Prior Art 1] Generally, a conveyor such as an IJ7 or an elevator is used as a means for vertically conveying construction materials at a construction site or the like.

Up until now, loading and unloading of loads onto these transport machines has often been done manually, which has had problems such as having to limit the weight of each load and overwork. .

For this reason, the following methods have been explored in the past for the purpose of saving labor and shortening work time.

(^) How to avoid loading and unloading materials using a forklift.

(B) Method of manufacturing a dedicated container truck and loading and unloading the cargo with the truck.

(C) A method in which the loading platform of a truck or elevator is converted into a roller conveyor and cargo is loaded and unloaded using this roller conveyor.

[Problems to be Solved by the Invention] However, in the conventional method A described above, it is not possible to arrange 7 oak trees on each floor due to the floor load, the transport of 7 oak trees, lifting equipment, economic scale, etc. It is difficult and
There are problems such as lower operating rates.

In addition, method B has problems such as empty containers taking up a lot of space, and the site having many obstacles such as floor differences and bars, making it difficult to move the trolley smoothly. .

Furthermore, with Method C, it cannot be used unless the loading platform and unloading position are at the same level, and there are many restrictions on the installation location. There are problems such as not being able to achieve this.

The present invention has been made to solve the above-mentioned conventional problems, and its purpose is to easily and quickly load and unload carts even in places where it is difficult to move carts etc. or even if there are some steps. It is an object of the present invention to provide a load-loading and unloading device for a lift that is efficient and economical.

[Means for Solving the Problems 1] In the lift loading/unloading device of the present invention, a crane body is rotatably installed at an appropriate position on a lift platform that moves up and down along a guide rail, and The crane is characterized in that the boom is mounted so that it can be raised and raised freely, and a hook is provided on the boom via a telescoping arm so that it can be moved up and down, and the installation position of the crane main body can be selectively changed. It is characterized by:

[Embodiment 1] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a guide rail, which is attached to a high-rise temporary structure 3 such as a steel pipe framework scaffolding via a support 2.

Reference numeral 4 denotes a lift frame, the base end of which is movably attached to the guide rail 1. The lift frame 4 is driven up and down by a drive wire 5 stretched along the guide rail 1.

Reference numeral 6 denotes a crane main body, and its rotation support shaft 7 is rotatably attached to the lift frame 4.

The mounting position of the crane main body 6 can be changed to the mounting position 8 or 9 as required.

A boom 10 is attached to the upper part of the crane main body 6 by a hydraulic sill 11 so as to be rotatable in the vertical direction. Reference numeral 12 denotes a telescoping arm, which is telescopically attached to the boom 10. A hook 13 is suspended from the tip of the telescoping arm 12 so as to be movable up and down. The rotational movement of the crane body 6, the downward movement of the boom 10 by the hydraulic cylinder 11, the telescopic movement of the telescoping arm 12, and the vertical movement of the 7-hole 13 are performed by the hydraulic pump 1.
The driving means 4 and the like are used to perform the driving independently or in conjunction with each other. 15 is a hydraulic tank.

In addition, 16 is a movable frame, which is attached to the tip of the above-mentioned upper frame 4 so as to be able to rise and fall, so that the floor area can be expanded.

Next, loading and unloading operations using the apparatus of the above embodiment will be explained.

First, when loading a load on a transport vehicle such as a truck onto the lift frame 4, as shown in FIG.
The inclination angle and the telescopic length of the telescoping arm 12 are movably set, and the seven hooks 13 are moved into the load S. 7 and hang 7 hooks 13 on the load S.

Subsequently, the crane 13 is raised to lift the load S, and then the crane body 6 is rotated again to position the load S on the lift frame 4, completing the transfer work.

Next, the cart is operated, raised along the guide rail 1, and stopped at the floor where the cargo is to be unloaded.

Once the crane 1J7 has been raised to the target floor, as shown in Figure 4, rotate the crane main body 6 toward the building.
While appropriately adjusting the position of the seven pallets 13 using the boom 10, telescoping arm 12, etc., the cargo is unloaded onto a pallet 17 prepared on the floor of the building.

[Effects of the invention 1 (1) It is possible to reduce the number of personnel and time required for loading and unloading materials on the tray.

(21 can be unloaded at a desired position without using a separate unloading gantry.

(3) Unloading work can be done without anyone getting on the truck.

(4) Loading and unloading of cargo can be carried out even by one person with working tools.

(5) Even if there are obstacles such as handrails or waist walls in the unloading area,
You can escape by dodging them and dropping the load onto the desired location.
