CONSTITUTION:A support column 2 is mounted on a truck 1 which is movable on a floor, and is provided thereto with a fixing means which can change the column 2 between a condition in which the support column 2 abuts against an upper slab D so as to be extended and fixed between the upper slab D and a floor C, and a condition in which the former condition is released. A frame 3 on which hold parts 3A for equipments and materials A are provided is elevatably provided using the support column 2 as a guide, and further, a nut member 5 threadedly engaged with a male thread 4 formed on the support column 2 and a motor 6 for rotating thereof are provided. Further, the frame 3 is coupled to the nut member 5 so as to be rotatable around the support column 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility equipment lifting device used when installing or replacing equipment such as an air conditioner, an air conditioning duct, a lighting fixture, and a pipe in a space above a ceiling.

[0002]

2. Description of the Related Art Conventionally, in order to install the above various equipments in a space above the ceiling, a chain block is attached to an anchor embedded in a ceiling slab, and the equipment is lifted to the space above the ceiling using the chain block. In addition, the equipment platform is mounted on a trolley that can move freely on the floor, using a so-called upper, which is attached via a lift cylinder that operates by gas pressure such as carbon dioxide gas in the cylinder, and is mainly used for duct construction and other lightweight equipment. I was carrying the equipment.

[0003]

However, when the chain block is used, the equipment cannot be hung up to the lower surface of the upper slab or its vicinity because it is hoisted, and the equipment cannot be hung up to the lower surface of the upper slab or its vicinity. To lift the equipment, it was necessary to lift it manually. On the other hand, when using the upper, the equipment can be lifted up to near the lower surface of the upper slab, but the equipment is supported by the lift cylinder that projects upward from the dolly and has a free upper end. There was room for improvement in terms of safety because it was easy for the equipment and equipment to hang up when unloading. An object of the present invention is to provide an equipment / equipment elevating / lowering device capable of raising and lowering equipment / equipment such as ceiling equipment / equipment to the vicinity of the lower surface of the upper slab safely and efficiently.

[0004]

A feature of the equipment lifting device according to the present invention is that a pillar is attached to a carriage that is movable on the floor, and the upper slab is pushed up to fix the pillar to the upper slab and the carriage. A fixing means that can be changed to a state in which the strut is released is provided, and a pedestal provided with a holding portion for equipment and equipment is provided so as to be able to move up and down using the pillar as a guide, and a nut member that is screwed into a male screw formed on the pillar. A motor for rotating it is provided, and the mount is rotatably connected to the nut member around the support.

[0005]

[Operation] Since the gantry is attached to the trolley via the columns, not only is there no need for structural construction such as embedding anchors to attach equipment to the ceiling slab, but the equipment attached to the gantry by moving the gantry The equipment can be moved freely in the horizontal direction. Since the fixing means are provided to fix at the upper and lower ends of the column, the elevating position can be freely changed, but the column that serves as a guide for the frame is stabilized and the frame is stably moved up and down, that is, , Can be raised. Since the pedestal is moved up and down by the motor, even a heavy object can be easily lifted to the space above the ceiling without requiring manual operation. Since the motor is connected to the pedestal through a so-called screw feed mechanism consisting of a nut and a male screw, a lightweight and small capacity motor can be used even though it is a drive type, and rotation of the nut member with respect to the male screw is stopped. This synergizes with the fact that the nut can be moved and fixed to the column and the structure for fixing the gantry can be eliminated, so that the structure can be simplified and the cost can be reduced, and the nut can be handled easily by hand.

[0006]

According to the present invention, therefore, equipment such as an air conditioner, an air conditioning duct, a lighting fixture, a pipe, etc., which is heavy and difficult to lift by a human hand, is installed in the space above the ceiling. The equipment required for maintenance can be lifted with excellent workability, accuracy, safety, and convenience.
Moreover, it has become possible to provide an equipment device lifting device that can be implemented at low cost.

EXAMPLE As shown in FIG. 1, an elevating device is used for installing equipment A represented by air conditioners, ducts, pipes, and lighting equipment in a space B above the ceiling. The support 2 is attached to the trolley 1 which is movable on C, and the upper slab D is pushed up to fix the stanchion 2 to the upper slab D and the trolley 1 and to release the support. A pedestal 3 provided with a holding portion 3A for the equipment A is provided so as to be able to move up and down by using the support column 2 as a guide, and a nut member 5 to be screwed into a male screw 4 formed on the support column 2 and a rotational operation thereof. A motor 6 is provided, and the gantry 3 is rotatably mounted on and supported by the nut member 5 around the support column 2 via a bearing 7. The trolley 1 is provided with wheels 1A (caster wheels or the like) whose direction can be freely moved, and can be switched between a state where it comes into contact with the floor C to prevent movement and a state where it is allowed to move away from the floor C. The fixture 1B is provided. The fixing means is a screw type jack or the like, which is interposed between the carriage 1 and the pillar 2 so that the pillar 2 is moved up and down with respect to the carriage 1.
The pedestal 3 has a mounting surface 3 on which the equipment A is mounted at one of the two positions sandwiching the mounting support portion on the nut member 5.
a and a hook 3b for suspending and supporting are provided as a holding portion 3A, and on the other hand, a plurality of balance weights 8 for preventing the pedestal 3 from tilting due to the weight of the equipment A held by the holding portion 3A are provided. A balance adjustment unit 3B for detachably attaching is provided. The motor 6 uses the nut member 5 as a rotor, and the exterior main body 6A that rotatably supports the rotor is provided in the groove 2a formed in the post 2 in a posture along the longitudinal direction thereof. The engagement prevents the column 2 from rotating. Reference numeral 9 is a remote controller for the motor 6. Also, the operator who is on a lifter or the like performs the installation and removal of the lifted equipment A.

It should be noted that although reference numerals are given in the claims for convenience of comparison with the drawings, the present invention is not limited to the structures of the accompanying drawings by the entry.
