Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to equipment and pipes which are detachably attached to a mobile body such as a forklift truck in order to attach equipments such as an air conditioner suspended from a ceiling and pipes such as an air conditioning pipe. Attachment for lifting and lifting.

[0002]

2. Description of the Related Art In recent years, in the construction of air conditioning equipment, there is a tendency to shift from a conventional single duct system to an individually distributed air conditioning system, and it is necessary to mount a large number of equipment and pipes on the ceiling. In order to attach such equipment and pipes, generally, a worker who lifted the equipment and pipes by using a chain block attached to a forklift or a ceiling floor slab, and climbed to a stepladder. The equipment and piping were fixed to the suspension bolts that were previously attached to the ceiling floor slab.

[0003]

However, in the case of the conventional example, the work is performed at a high place with the equipment and pipes being lifted, and there is an unstable heavy object in the vicinity, which is dangerous. When lifting with a forklift, it is necessary to fix the equipment and pipes with wires so that they will not roll.In addition, the equipment and pipes may not be There is a risk that it will fall into the ground, and there is a drawback that the workability is low and the workability is low because it requires many workers and labor.

The present invention has been made in view of the above circumstances, and is useful for safely and efficiently attaching equipment / pipes and for saving labor.
The purpose is to provide an attachment for lifting piping.

[0005]

In order to achieve the above-mentioned object, the attachment for lifting equipment and pipes according to the present invention has a first supporting frame having a mounting portion which is detachably attached to a mobile body. , A second supporting frame is provided so as to be displaceable up and down through the first drive mechanism, and a vertical posture for holding the equipment and piping in a horizontal posture and a horizontal posture for holding the equipment and pipes in an upward posture are provided on the second supporting frame. The third support frame is attached to the first support frame so that the posture can be changed, and the device / pipe holding member is provided on the third support frame so that the facing distance can be changed via the second drive mechanism.

[0006]

According to the construction of the equipment / piping lifting attachment of the present invention, when the equipment / piping is transported horizontally,
With the third support frame in a vertical posture, the first support frame is attached to a mobile body such as a forklift and placed on the ground by using the tilting and raising / lowering operations provided in the mobile body. It is possible to hold the equipment and pipes in a horizontal position and then hold them in a horizontal position for transportation. On the other hand, when lifting the equipment / pipes and attaching them to the ceiling floor slab, etc., the posture of the third support frame is changed to a horizontal posture, and the tilting and raising / lowering operations provided in the mobile body are used. Hold the equipment / pipes placed on the ground via a stand, etc. in a horizontal position and then in an upward position, lift in that state, and then operate the first drive mechanism to lift. Weights and equipment / pipes can be lifted and held in high places.
