Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a transport device used when transporting small construction members such as blocks used as fences and outer walls to an upper installation position.

[Prior art]

Conventionally, when performing construction work at a high location using these small construction members, for example, when stacking blocks, etc., a plurality of blocks are first placed on the assembled work scaffold by lifting it with a crane or the like.

Thereafter, either the worker on the work scaffold lifts the material himself and places it in the stacking position, or the worker lifts it again using a crane or the like and places it in the stacking position by the worker.

[Problems to be solved by this invention]

However, according to this conventional construction work, it is necessary to assemble a scaffold for workers to carry out work at a high position, and it is also necessary to temporarily place small construction members on this work scaffold.

In addition, it requires additional equipment such as a crane attached to the truck, which is troublesome and time-consuming, and increases construction costs.

This invention was made in consideration of the above-mentioned circumstances! It was invented by
Its purpose is for construction work at elevated locations using small construction components, such as scaffolding or other material equipment.

[Means for solving problems]

According to the present invention, a work platform serving as a work platform is provided on a self-propelled mobile trolley so as to be movable up and down, thereby forming a transport device.

The hoisting device, which is rotatably attached to the workbench at least at a higher level than the worker on the workbench in a horizontal plane, and is used to move the lifting tool for small construction members up and down, is moved to the inside and outside of the workbench. A movable support arm is provided, and by appropriately moving the support arm and workbench, construction work for small construction members is carried out at a predetermined position (high position).

〔Example〕

The present invention will be explained below with reference to illustrated embodiments.

The transport device 1 includes a workbench 3 that is provided so as to be able to rise and fall onto a self-propelled mobile cart 2, and a workbench 3 that is rotatable in a horizontal plane at a position that is at least higher than the worker 4 on the workbench. It is equipped with a support arm 8 which is pivotably attached to the workbench 3 and can move a hoisting device 7 for vertically moving the hanging tool 6 for the small construction member 5 to inside and outside positions of the workbench 3.

(See Figure 1, Figure 2, and Figures J and 7) The self-propelled mobile cart 2 is movable by an endless track device 2a, and is provided with a lifting device 2b for a work platform 3 on the upper part.

On the workbench 3, each column 9 is provided at the four corners of the upper surface, and a ceiling portion 10 is provided on each column 9.
It is equipped with a handrail 11 provided between each support 9, and a control box 12 that controls the movement of the trolley 2 and the lifting and lowering of the work platform.

The support arm 8 includes a spear 1 arm 8a whose one end is pivotally attached to the ceiling 10 of the workbench 3 so as to be rotatable in a horizontal plane, and a spear 1 arm 8a whose other end is rotatable in a horizontal plane. It consists of two arm parts 8b, one end of which is movably pivoted, and a hoisting device 7 suspended from the other end. (Refer to Figure 3 and Figure 4 of the spear.) With this support arm 8, as shown in Figure 5 of the spear, the longitudinal distance of the arm portion 8a of the spear 1 is defined as a radius, centered on the center pivot position of the ceiling portion 10. On the circle, centering on the first arm part 8a that can move the shaft attachment part of the spear second arm part 8b and the shaft attachment part to the fang first arm part 8, the longitudinal direction of the spear second arm part 8b is centered. The hoisting device 7 can be freely moved to an appropriate position within the circle 13 by means of the fang 2 arm portion 8b that allows the hoisting device 7 to be moved on a circle having a distance as a radius.

Therefore, the support arm 8 moves the hoisting device 7 to the workbench 3.
It becomes possible to move it to the inside and outside positions.

When transporting a small construction member 5 (a heavy block in this embodiment) to a predetermined high construction position using the transport device 1 having such a configuration, first the workbench 3 is moved as shown in Fig. 2.
While the robot is lowered, a plurality of small construction members 5 are placed on the workbench 3, and the mobile cart 2 is moved below the position to be transported. When the mobile cart 2 reaches a position below the position to be transported, the movement is stopped and fixed.

Next, the workbench 3 is raised to a position where the work can be performed by the worker 4. Then, use the hoisting device 7 of the support arm 8 to lift up the small construction member 5 on the workbench 3 supported by the hanging tool 6, and move it to the construction position outside the workbench 3 using the support arm 8.

After that, construction work is performed by worker 4. (See Figures 6 and 7.) In this way, the small construction member 5 is transported to a predetermined position by moving the moving cart 2, raising and lowering the work platform 3, and moving the support arm 8 as needed.

Note that the hoisting device 7 in this embodiment is a hoist, and the hanging device 6 is attached via a balancer 14. Since the small construction member 5 is a heavy block in this embodiment, the hanging tool 6 has a V-shaped configuration that can support the small construction member 5. (See Fig. 4) However, the hoisting device 7 and the hanging device 6 of the present invention are not limited to those of this embodiment, and may be of any type suitable for the type of the small-sized construction member 5.

Also, any device that can move the lifting device and hoisting device of the workbench to the inside and outside of the workbench, and any device that can manually move the hoisting device to the inside and outside of the workbench. But that's fine.

〔Effect of the invention〕

The present invention has the above configuration and has the following effects.

In order to have a work platform that can be raised and lowered on a self-propelled mobile trolley,
There is no need to assemble work scaffolding for construction work in high places.

In addition, the workbench is equipped with a support arm that can manually move the hoisting device for small construction parts, at a position higher than the worker on the workbench. It can be hung at a location convenient for construction work (see Figures 1 and 7) and easily moved to a predetermined position.

For these reasons, by using the transportation device of the present invention, construction work such as stacking small construction members can be easily performed by workers in a short time without the need for scaffolding, special lanes, etc. .
