Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lift for construction, and more particularly to a lift for an inclined portion used for an inclined portion such as a stair.

[0002]

2. Description of the Related Art In construction work, construction lifts are provided for loading materials. In the slopes such as stairs,
Generally, monorails for construction and lifts for slopes are used. In these, a carrier is placed on a rail installed on an inclined portion, and materials are transported.

[0003]

However, in the conventional apparatus, the material is transported in an inclined state in order to travel on an inclined portion. For this reason, during transportation of the finished interior material and the like, the balance may be lost, and the material may be damaged, leading to a reduction in workability.

[0004] Accordingly, an object of the present invention is to provide a skew lifting device capable of always carrying a lifting material in a horizontal state.

[0005]

According to the present invention, a pair of right and left traveling rails are provided on an inclined conveyance path in two vertical stages, and rails with a rack are provided between the traveling rails, and these rails are level-adjusted. A drive device having a sprocket that can be adjusted in height with a jack and meshes with the rail with a rack and rolls, and a pair of wheels that rolls on each of the running rails and a pair of which is restricted from lateral movement and rolls. A sloping lift device comprising a loading platform having a drive unit, and a tip end of the driving device and a middle of the loading platform are axially connected by a push arm.

In practicing the present invention, the drive unit is provided with a motor for rotating the sprocket.

[0007] In practicing the present invention, it is assumed that the driving device has two sprockets.

In carrying out the present invention, it is assumed that the carrier has three pairs of left and right wheels. Drive the drive,
When the bed moves on an inclined portion such as a staircase, the bed is kept horizontal, so that the materials mounted on the bed are also transported while being kept horizontal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 to 4, the inclined conveying section comprises a step k, FIG. 1 shows a horizontal section, FIG. 2 shows a front section of the inclined conveying section, FIG. 3 shows an inclined conveying section, and FIG. Shows the end of the transport section. The traveling rails 1 forming a pair on the left and right are divided into upper and lower traveling rails 1A and 1B in the inclined conveying section, and are connected to each other by a fitting 1C.

A U-shaped rail is used for the lower traveling rail 1-B so as to restrict the left and right movement of a pair of wheels of the loading platform described later.

As shown in FIG. 5, between the running rails 1,
A rail 2 with a rack is provided.

The traveling rails 1-A and 1-B and the rail 2 with a rack can be adjusted in height by a level adjusting jack 3.

A driving device 4 and a loading platform 5 are provided, and the driving device 4 engages with the rack-equipped rail 2 to roll 2
It has two sprockets 6, which are driven by a motor 7 via a chain 8.

The loading platform 5 comprises a first pair of left and right wheels 9 located below and a second and third pair of wheels 9 located above it.
The first wheel 9 rolls in the lower traveling rail (U-shaped rail) 1B while the left and right movement is restricted, and the second and Three wheels 10,
11 rolls on the upper running rail 1A.

The distal end of the drive unit 4 and the center of the carrier 5 are connected by a push arm 12 to the shafts 12a and 12b.

In FIG. 2, when the driving device 4 is driven,
The carrier 5 approaches the inclined part k. In the inclined portion, the running rail 1 is divided into an upper running rail 1A and a lower running rail 1B, the first wheel 9 is restricted from moving left and right, and rolls on the lower running rail 1B, and the second wheel is on the upper running rail 1A. , And the third wheel rises as it rises.

In FIG. 3, the driving device 4 travels diagonally, while the loading platform 5 travels while keeping the level. Therefore, the material loaded on the bed 5 also keeps the level.

In FIG. 4, when approaching the horizontal portion, the upper traveling rail 1A and the lower traveling rail 1B overlap,
It becomes the running rail 1. The first wheel 9 rolls inside the traveling rail 1, and the second and third wheels 10, 11 roll on the upper part.

[0019]

The present invention has the following advantages because it is constructed as described above. (1) Materials can be transported while always maintaining a horizontal state. (2) No special equipment is required to keep the bed and materials horizontal. (1) Therefore, it is most suitable for transporting materials on inclined parts, and can also be used for general cargo handling.
