DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for lifting and lowering equipment such as air-conditioning equipment, air-conditioning ducts, lighting equipment, piping and the like when installing or replacing the equipment in a space above a ceiling.

[0002]

2. Description of the Related Art Conventionally, a chain block is mounted on an anchor embedded in a ceiling slab, and the equipment is lifted into the space above the ceiling using the chain block. In addition, using a so-called upper in which the equipment mounting table is mounted on a trolley that can move on the floor via a lift cylinder that is operated by gas pressure such as carbon dioxide gas in a cylinder, lightweight equipment is mainly used for duct construction and the like. He was lifting equipment.

[0003]

However, when using a chain block, the equipment cannot be lifted to the lower surface of the upper slab or near the lower surface of the upper slab due to the lifting. Lifting the equipment required manual lifting. On the other hand, when using the upper, the equipment can be lifted to near the lower surface of the upper slab, but the equipment is supported by a lift cylinder that protrudes upward from the bogie and has a free upper end. There was room for improvement in terms of safety because it was easy to wobble when unloading certain equipment. SUMMARY OF THE INVENTION An object of the present invention is to provide a facility equipment lifting device capable of lifting and lowering equipment such as ceiling equipment close to the lower surface of an upper slab with good workability and safety.

[0004]

The feature of the equipment lifting apparatus according to the present invention is that a support is mounted on a truck movable on the floor, the support is pushed up to the upper slab, and the support is stretched and fixed to the upper slab and the floor. A fixing means that can be changed to a state in which the tension is released is provided, a base provided with a holding portion for equipment and equipment is provided so as to be able to move up and down using the support as a guide, and a nut member screwed to a male screw formed on the support. Rutotomoni provided a motor for rotating the it, the gantry lift drive mechanism by supporting the frame on the nut member
And the rotatable connection of the gantry to the nut member around the support, and the support of the gantry with respect to the support
Equipment and equipment held by the holding unit regardless of the vertical position
Balance adjuster to prevent the gantry from tilting due to the weight of
Is provided .

[0005]

[Function] Since the gantry is attached to the trolley via the pillar, not only is there no need for any construction work for mounting equipment on the ceiling slab such as embedding of anchors, but also to the holding part of the gantry by moving the gantry. facilities equipment was held, it can move freely in the horizontal direction. Because provided fixing means are so as to secure the two ends of the upper and lower struts, yet those of vertical position can be freely changed also stabilize raising descending to the gantry via a strut comprising a guide frame be able to. Because are so as to lift more frame to the frame lift drive mechanism, it can be lifted easily roof space facility equipment without requiring even manual operation power in some of the weight. Since the motor is connected to the frame via a so-called screw feed mechanism consisting of a nut and a male screw, it is possible to use a light-weight and small-capacity motor as a drive type, and stop the rotation of the nut member with respect to the male screw. By doing so, it is possible to move and fix the nut to the column and eliminate the need for a structure for fixing the gantry, so that the structure can be made simple and inexpensive, and it can be handled easily by hand. Frame on nut member
The base is rotatably connected around the column, so the equipment
When installing or replacing the
And the fixing means is used to secure the

Rotate the equipment and move it to the appropriate working position for the equipment.
Movement and alignment will damage the weight balance of the gantry.
Can be done without any After all, you can move on the floor
Attach the support to the trolley, push it up to the upper slab and
The state where it is stretched and fixed to the upper slab and the floor, and its stretch
Equipment that can be changed to a state in which
A gantry equipped with a holding part for equipment, using the support as a guide
It is provided so as to be able to move up and down, and is screwed into a male screw formed on the support
Provide a cutting member and a motor for rotating the cutting member
At the same time, the gantry is supported by the nut
Constituting a lowering drive mechanism, the gantry is mounted on the nut member,
While being rotatably connected around the column,
Irrespective of the vertical position with respect to the support,
To prevent the rack from tilting due to the weight of the installed equipment.
Lance adjustment is provided, so it is installed in the space above the ceiling
The operation of raising and lowering equipment when changing or replacing
It can be performed in a stable posture with a lance.

[0006]

Effect of the Invention] Thus, according to the present invention, air conditioning equipment and air conditioning ducts, lighting appliances, in piping, heavy manually, also the movement of bulky carry and lift it very difficult facilities machine member , Installed in the space above the ceiling or replaced
And the raising and lowering of the facility equipment that is required in the case of or, installation position
Positioning is easy and extremely workable and accurate.
In addition, it can be performed safely and simply in a well-balanced and stable position ,
In addition, it has become possible to provide a facility equipment lifting device that is simple in structure and can be implemented at low cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, an equipment equipment lifting device is an equipment equipment A represented by an air conditioner, a duct, piping, and lighting equipment.
Is installed in the space B above the ceiling, etc., and the support 2 is attached to a trolley 1 movable on a floor C,
Fixing means is provided which can be changed between a state in which the upper slab D is pushed up to stretch and fix the column 2 to the upper slab D and the bogie 1 and a state in which the strut is released, and a gantry 3 having a holding portion 3A for the equipment A. and the strut 2 vertically movably provided as a guide, provided <br/> a motor 6 for rotating the it a nut member 5 screwed to the formation of the male screw 4 on the support 2 Rutotomoni, the nut The gantry 3 is supported by a member 5.
To form a gantry lifting drive mechanism,
When the gantry 3 is rotatably connected around the column 2,
To, the weight of the equipment equipment A which is held by the holding portion 3A
A balance adjustment unit 3B for preventing the gantry 3 from tilting.
It is configured. The gantry 3 is connected via a bearing 7
And rotatably mounted on the nut member 5 around the column 2
Is supported. The cart 1 is provided with wheels 1A (caster wheels or the like) that can be changed in direction for movement, and can be switched between a state in which the cart 1 is in contact with the floor C to prevent movement and a state in which the cart 1 is separated from the floor C and allows movement. A fixture 1B is provided. The fixing means is a jack of a screw type or the like in which the column 2 is interposed between the carriage 1 and the column 2 so as to move up and down with respect to the carriage 1. The gantry 3 has a mounting surface 3a on which the equipment A is mounted and a hook 3b for suspending and supporting the holding device 3A at one of two positions sandwiching the mounting support portion for the nut member 5 as a holding portion 3A. And the other equipment
