Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction material lifting device for carrying materials and equipment to each floor at a construction site or the like.

[0002]

2. Description of the Related Art In construction work, lifting and horizontal transportation of construction materials occupy a large weight in field work. Of these, hoisting occupies a fairly large weight, and materials of other varieties are concentrated and carried in various packing styles, especially at the finishing work and equipment construction stages, so if not hoisting quickly, it will have a large impact on the process. .

Therefore, in recent years, a pair of guide pillars are erected at the opening of the outer wall of the building body, and the elevating table for suspending the slide forks is moved up and down along the guide pillars, and the materials are used by the slide forks in the building. A construction material lifting device, which was designed to be loaded into the building, came to be used.

[0004]

According to this apparatus, the material can be quickly brought into each floor, but there are the following problems.

Since a dedicated electric motor was used as a power source for lifting, the own weight of the lift is very heavy because it is equipped with the electric motor, a safety device, and a special slide mechanism. A special protection device was needed. Also, when loading materials that were transported by forklifts etc. into the lift, it was necessary to reload the load. In addition, a dedicated operator was required to operate the lift.

The present invention has been made to solve the above-mentioned problems of the conventional apparatus. The object of the present invention is not to require a dedicated electric motor as a power source for lifting and to provide a special slide mechanism. To provide a lifting device for unnecessary construction materials, and to provide a lifting device for construction materials that does not require load reloading work for lifting and does not require a dedicated operator to operate the lift. is there.

[0007]

In order to achieve the above-mentioned object, according to the present invention, four racks each provided with a rack are provided along the opening of the outer wall of the building frame so as to present a flat quadrangle. The pillars are erected on the front, rear, left and right, and the pinions are meshed with the racks of each pillar, and the pinion that meshes with the racks of the front and rear pillars are driven and connected by the pinion shafts. In addition, the worm gears are drive-coupled to each other by a worm shaft, and a power wheel driven by traveling wheels such as a forklift is integrally provided on the worm shaft so as to rotate integrally, and the pinion, the pinion shaft, the worm gear, the worm shaft, the power wheel, and With a loading platform on which a traveling vehicle such as a forklift is mounted, the traveling wheels of the forklift are used as a power source along the pillar. Construction materials made constitutes a lift for descending lifting device is provided.

[0008]

[Function] A forklift loaded with materials is directly placed on the platform of the lift, brakes are applied to wheels other than the drive wheels of the forklift, and the drive wheels are rotated in the same procedure as traveling to rotate the power wheels provided in the lift. The rotational force of the power wheels is transmitted to the pinion that meshes with the racks of the four columns via the worm shaft, the worm gear, and the pinion shaft, and the loading platform on which the forklift or the like is mounted rises. After reaching the specified floor, the forklift etc. will self-propell and carry the materials into the building.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, an opening B is provided in an outer wall A of a building in which building work has been substantially completed, and materials are carried into the building through the opening B. As shown in FIG. 2, along the opening B of the outer wall A, four pillars 1A, 1B, 1C, 1 each equipped with a rack 2 so as to have a planar quadrangle are provided.
D is erected in front, back, left and right. The pinion 3 is engaged with the rack 2 of each of the columns 1A to 1D, and the pinions 3 engaging with the front and rear columns 1A and 1B and the columns 1C and 1D are drivingly connected by the pinion shafts 4A and 4B, respectively. Worm gears 5A and 5B are integrally provided on the pinion shafts 4A and 4B, respectively, and the worm gears 5A and 5B are drivingly connected to each other by a worm shaft 6. The worm shaft 6 is rotationally driven by the drive wheels D of the forklift C, and as shown in FIGS. 2 and 3, the worm shaft 6 is
A power wheel 7 is provided integrally with the wheel, and the power wheel 7 and the guide wheel 8 are provided.
And a driving wheel D of the forklift C is placed on the belt 9, and the rotational force is transmitted by the frictional force between the tire and the belt 9. These power transmission mechanisms are provided on the luggage carrier 10, and together with the luggage carrier 10 form a lift.

The forklift C loaded with the material F is directly loaded with the drive wheels D on the belt 9.
Put it on top. Wheel E other than drive wheel D of forklift C
Apply the brake to and rotate the drive wheel D in the same procedure as running.
When the tire starts to rotate, the belt 9 starts to move due to frictional force, and this is used as a power source for lifting. That is, the power wheel 7
Rotates, and the rotational force is the worm shaft 6 and the worm gear 5.
A, 5B, pinion shafts 4A, 4B, and the front, rear, left, and right columns 1
It is transmitted to the pinion 3 that meshes with the rack 2 of A to 1D,
The loading platform 10 rises. When the loading platform 10 reaches a predetermined floor, the forklift C is self-propelled and the material F is loaded into the building through the opening B of the outer wall A.

[0011]

According to the present invention, the following effects can be obtained.

(1) Forklift, directly to the lift,
Vehicles can get in and carry loads to the desired floor without reloading.

(2) A driver of a forklift or the like may directly drive the vehicle in the same manner as driving a vehicle, and a dedicated lift operator is not required.

(3) Since the structure is very simple without the need for attaching a dedicated motor as a power source for lifting, a safety device, a special slide mechanism, etc., the weight of the lift is light and the cost is low.

(4) Since the worm gear is inserted in the middle of transmission, the brake is unnecessary.
