[Industrial applications]

 The present invention relates to a lifting device in construction work, and in particular, it uses a temporary lift installed along the outer wall surface of a building or in an elevator shaft or a shaft using an opening for construction. It concerns a lifting device that can load and unload cargo.

[0002]

[Problems to be solved by conventional techniques and devices]

 In the conventional construction work of this type, hoisting of materials or equipment for construction work is carried out using heavy equipment such as temporary lifts and cranes. Therefore, in the loading / unloading section of the luggage, manual work is required and it is often dangerous, so that the loading / unloading work efficiency and the use efficiency of the temporary lift are extremely high. bad. In addition, since there is a girder at the bottom of the temporary lift platform at the luggage loading area, a ramp or pit for loading luggage is required.

Therefore, there arises a technical problem to be solved in the loading / unloading section of the load so as to reduce the manual work and enable the efficient lifting work. Aims to solve the problem.

[0004]

[Means for Solving the Problems]

 The present invention was proposed in order to achieve the above-mentioned object, and a girder with an elevating device is laid on a guide rail that is erected along the outer wall surface of the building or on the shaft inside the building. , A forklift with a turntable is removably attached to the lower part of the girder, and a guide rail for traveling of the forklift is connected continuously from the luggage loading part on the outside into the shaft, and further on the upper part of the shaft. Also, in this invention, the lifting device for construction work is provided, characterized in that the guide rails for traveling of the forklift are connected continuously to the inside of the shaft and the cargo unloading portion.

[0005]

[Action]

 The girder descends along the outer wall of the building or along a guide rail provided inside the shaft. Then, the fork lift, which is detachably attached to the girder, disengages from the girder and moves to the luggage loading section along a guide rail that is continuous with the luggage loading section. Therefore, the load is directly transferred to the forklift from a truck or the like which is loaded with the load at the load loading section and is waiting. The forklift receiving the load at the load loading section returns into the shaft along the guide rail of the load loading site, and the forklift is attached to the girder mounted on the guide rail in the shaft, The lifting device installed on the girder raises the inside of the shaft. Thus, since the guide rail on which the forklift can travel is extended between the shaft and the stockyard of the luggage, the forklift is attached to the guide rail within the shaft, and The forklift is removed from the girder and runs to the upper part of the stockyard. The forklift that has traveled to the upper part of the stockyard rotates to an arbitrary position via the turntable, and then the jack is used to lower the fork to drop the load onto the stockyard.

In addition, after unloading the load from the stockyard, the fork of the forklift is lifted and rotated to the original position via the turntable to return to the inside of the shaft along the guide rail, and then to the inside of the shaft. The lower part of the waiting girder is attached again, and the lifting device of the girder descends to the lower part of the shaft, and the above-mentioned operation is repeated.

【Example】

 Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. For convenience of description, a configuration which is conventionally known will be described at the same time. In the figure, reference numeral 1 is a space above and below the outer wall surface of the building or a space such as a shaft provided inside the building, and a guide rail 2 is erected in the space 1. . A girder 3 with an elevating device is bridged over the guide rail 2, and is formed so as to be vertically movable along the guide rail 2 by the elevating device.

Further, a forklift 5 is removably attached to the lower surface of the girder 3 via a turntable 4, and the forklift 5 has a fork 5a vertically movable by a jackie (not shown). It is provided. Further, a guide rail 6 for traveling of the forklift 5 is provided in a lower portion of the space portion 1 above the lower portion of the space portion 1 and above the luggage loading portion 7. A truck 8 or the like loaded with luggage is waiting in the luggage loading section 7. Further, since the load 9 loaded on the truck 8 is placed on the upper surface of the pallet 10, the fork 5a of the forklift 5 is inserted into the lower surface of the pallet 10 to place the load 9 together with the pallet 10 on the fork 5a. Can be transferred to.

Further, as shown in FIG. 4, the luggage loading section 7 can be provided at two or three locations on the left and right sides of the front surface of the space section 1 and the front section. In this case, extended rails 6a, 6a, 6a of the guide rails 6, 6, 6 which are orthogonal to each other are attached to the respective luggage loading portions 7, 7, 7, and the extended rails 6a, 6a, A swivel rail 6b that can be connected to the 6a is provided so as to swivel ahead of the extended rails 6a, 6a, 6a. Therefore, no matter which luggage loading section 7 the truck 8 carrying the luggage is waiting on, the turning rail 6b is swung to extend the extension rail 6a provided on the luggage loading section 7 on which the truck 8 is waiting. To match. In that case, the forklift 5 can travel to the luggage loading section 7 and receive the luggage 9 on the truck 8. Further, when traveling to the lower surface of the girder 3 standing by in the space 1, the swivel rail 6b is swung again to match the guide rail 6 in the space 1 to move the forklift 5 to the girder 3. The lower surface of the girder 3 is mounted on the lower surface of the girder 3.

Further, a guide rail 12 on which a forklift 5 can travel is provided between the luggage unloading portion 11a of a luggage stockyard 11 provided on a predetermined floor above the space portion 1 and the space portion 1, When the forklift 5 reaches the guide rail 12 by the ascent of the girder 3, the forklift 5 is detached from the girder 3 and mounted on the guide rail 12, and travels to the upper part of the luggage lowering part 11a to move to the fork 5a. And the fork 5a is pulled out from the pallet 10, the load 9 placed on the fork 5a can be dropped onto the load unloading portion 11a. At this time, when the fork 5a reaches the upper surface of the load unloading portion 11a, it faces the direction of the space portion 1. Therefore, the fork 5a is turned 180 degrees through the turntable 4 to lower the fork 5a. As described above, the load 9 is lowered from the fork 5a.

When the load 9 is dropped onto the load lowering portion 11a in this way, the fork 5a is pulled up by the jackie, turned 180 degrees again through the turntable 4, and the guide rail is turned. It travels to the lower surface of the girder 3 waiting in the space 1 via 12 and is attached to the girder 3 apart from the guide rail 12. Thus, the girder 3 is lowered by the elevating device, and carries out the loading operation as described above.

Since each of these operations can be automatically performed by computer control, the loading and unloading operations of the load 9 can be reduced by manpower, and the temporary lift device can be very efficiently installed. It can be used to lift construction equipment. Further, a loading platform (not shown) is attached to the upper part of the girder 3 to form a mechanism that can be used as an ordinary long-span elevator, which can be used according to each application and situation. It is also possible to remove 5 and attach a self-propelled carriage (not shown) or the like in place of the forklift 5 to enable lifting.

It should be noted that the present invention can be modified in various ways without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified version.
