DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device for mounting ceiling boards, lighting fixtures and other objects to be mounted substantially horizontally to buildings, underground shopping centers and other structures.

[0002]

2. Description of the Related Art For example, when decorating the ceiling of a building, an operator attaches the ceiling board to a predetermined place by screwing or nailing while supporting the ceiling board under the ceiling board.

[0003]

Generally, performing an upward operation such as screwing or nailing while supporting an object to be mounted horizontally on the lower side thereof is a heavy labor for the operator. In particular, when the horizontal object is heavy and large, the operation involves danger.

[0004] It is an object of the present invention to provide a mounting device for mounting a horizontal object to a structure, which can reduce labor and avoid danger during upward work.

[0005]

According to the present invention, there is provided a mounting apparatus for mounting an object to be mounted on a building and supporting the mounting table substantially horizontally, a means for vertically moving the mounting table, A rotating arm is attached to the gantry or the elevating means so as to be rotatable in a horizontal direction, and a working means is attached to a free end of the rotating arm so as to be able to elevate and lower.

The elevating means is attached to, for example, a trolley so that the gantry can be moved together with the elevating means. The mounting device is brought to a place where the object is to be mounted horizontally, the object is placed on the gantry, and the gantry is raised. Thereafter, the rotating arm is rotated to guide the working means to a predetermined position below the mounted object. The work means at the predetermined position is raised and the mounting work is performed.

[0007] Since the object to be mounted is supported by the gantry, it is not necessary for the operator to support the object to be mounted on the lower side, which is safe.

Since the work to be mounted is supported by the gantry and work is performed by the work means, upward work can be eased and work efficiency can be improved.

In a preferred aspect of the present invention, the elevating means comprises a single cylinder mechanism and is coupled to the gantry at the center of the gantry, and the rotary arm is rotatable about the elevating means. It is attached to the elevating means and is raised and lowered by the elevating means.

Since the lifting / lowering means is a single cylinder mechanism, a plurality of cylinder mechanisms require a synchronous lifting / lowering operation, but the platform can be raised / lowered without such complication.

Since the lifting / lowering means is located at the center of the gantry and the rotary arm is rotatable about the lifting / lowering means, it is possible to cope with a symmetrical work on the object to be mounted simply by rotating the rotary arm.

Since the rotating arm is raised and lowered by the lifting means, the gantry and the rotating arm can be raised and lowered while maintaining the same positional relationship between the working means and the gantry.

In another preferred aspect, the rotating arm is mounted on the elevating means so as to be rotatable in a horizontal direction, and the rotary arm is mounted on the first arm so as to be rotatable in a horizontal direction. And a second arm to which the working means is attached.

Since the degree of freedom of the rotating arm and thus the degree of freedom of the working means is substantially infinite, it is possible to work at any place on the object to be mounted. In addition, the work can be performed even if the mounted object is not accurately placed on the gantry. Thereby, work efficiency can be further improved.

Further, it is preferable that the work means can be rotated in a horizontal direction.

Rough positioning by the rotating arm,
Thereafter, the working means itself is rotated, and accurate positioning can be performed. This allows, especially when the rotating arm is long,
Ease of work can be ensured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a mounting device comprises a gantry 10, a lifting means 12, a rotating arm 14,
Working means 16.

The gantry 10 supports a ceiling board, a lighting fixture, a duct for air conditioning and other objects to be mounted substantially horizontally. In the illustrated embodiment, the mounted object 18 is a ceiling board, and the gantry 10 includes two frames 20 having a substantially U-shaped planar shape, and an auxiliary frame 22 fixed on the frames 20. . The two frames 20 are connected to the elevating means 12 described below. The ceiling board rests on the auxiliary frame 22.

Means 12 for vertically moving gantry 10 up and down
Is an air cylinder mechanism in the embodiment shown in detail in FIG. 3, which is connected to the cylinder 24, a piston (not shown) slidably disposed in the cylinder 24, and protrudes from the cylinder 24. And a piston rod 26.

The connecting member 28 is connected to the piston rod 26 by a screw, and the second connecting member 30 is connected to the connecting member 28 by a screw. On the other hand, the second connecting member 30 is interposed between the two frames 20, and the two frames 20 and the second connecting member 30 are connected by screws, and the frame 1
0 is connected to the lifting means 12 at its center.

The rotary arm 14 is attached to the gantry 10 or the elevating means 12 so as to be rotatable in the horizontal direction.

In the illustrated embodiment, the rotating arm 14 is attached to the elevating means 12 so as to be rotatable about the elevating means 12, and the first arm 32 and the first arm 32 are moved up and down by the elevating means 12. 32 and a second arm 34 rotatably attached to the second arm 32.

As shown in FIG. 3, a cylindrical guide 36 is supported on the shoulder of the connecting member 28 and is arranged so as to cover the cylinder 24 of the lifting / lowering means 12. Guide 36
Is movable in the axial direction of the cylinder 24. On the other hand,
A boss 33 of the first arm 32 is rotatably attached to a guide 36 via a bearing 38. The bearing 38 receives a reaction force applied to the rotating arm 14 from the working means 16 described later.

As shown in FIG. 1, the first arm portion 32 is formed so as to have an L-shaped front surface, and extends horizontally and downward from the elevating means 12. As shown in FIG. 4, a connecting member 40 is attached to the lower end of the first arm 32.
Are connected, and the boss 35 of the second arm portion 34 is
It is rotatably attached to the connecting member 40 via the bearing 42. The bearing 42 receives a reaction force from the working means 16.

The work means 16 selects an automatic screwing machine, an automatic nailing machine, or the like according to the work to be added to the object 18 and is attached to the free end of the rotating arm 14 so as to be able to move up and down.

In the embodiment shown, a support member 46 having a vertical rod 44 is connected to the free end of the second arm portion 34, and a horizontal portion 49 of an L-shaped operation handle 48 is rotatably inserted into the vertical rod 44. It is. A cylindrical guide 50 integral with the working means 16 is rotatably inserted into the vertical rod 44, while a bracket 52 provided on the guide 50 is provided.
