Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trolley device provided on a ceiling and a hanging metal fitting for the trolley device.

[0002]

2. Description of the Related Art A trolley rail is provided on the ceiling of a building where mechanical devices and the like are installed, and is used for removing and reattaching machines for repair and inspection.
When loading and unloading the machine, there is no problem if the carrier or truck is directly inserted into the building, but if it is not available, a temporary device must be manufactured and loaded and unloaded.

FIG. 6 is a diagram showing an example of loading and unloading a gas turbine. A loading / unloading door 2 is provided in the gas turbine chamber 1, and a trolley rail 3 is provided on the ceiling from directly above the gas turbine 4 to the loading / unloading door 2. Since other equipment and piping are installed on the floor,
It is not possible to carry in / out carriages into the room. For this reason, it is necessary to install the temporary trolley rail 5 from the indoor position to a position where an outdoor carriage or the like enters. A temporary trolley rail 5 is arranged as shown by a broken line, one end is attached to the ceiling so as to be connected to the existing trolley rail 3, and the other end is supported by a temporary gate structure 6 as shown in FIG. The gas turbine 4 is carried in and out of the gas turbine chamber 1 by these temporary devices.

In the case of equipment such as the gas turbine 4, a hoisting piece is provided at the hoisting position, and a hoisting metal fitting attached to the trolley device is also prepared specifically for the hoisting piece. FIG. 8 is a diagram showing an example of such a suspension fitting. The hanging fitting 7 includes a horizontal member 8, a joining fitting 10 for joining the horizontal member 8 to the trolley 9, and a horizontal member 8
The lifting levers 11 and 12 are provided at both ends of the. A lifting lever 11 is fixed to one end of the horizontal member 8 by welding, but a lifting lever 12 is axially slidably and rotatably attached to the other end of the gas turbine 4. It is easy to engage with the lifting piece 13. The hoisting piece 13 and the hoisting levers 12, 13 are joined to each other with bolts and nuts 14.

[0005]

A vehicle or the like is required to carry out what is carried by the indoor trolley device to the outside. However, if these do not enter the room, a temporary trolley rail is placed outside. It must be provided and carried out, and similar equipment is required when carrying in. Such a temporary device may be manufactured each time when the loading / unloading frequency is low, which is expensive. In addition, when it was first manufactured and stored, it was difficult to secure and manage the storage location. Especially when the gas turbine is for ships and the gas turbine room is inside the ship, there is not enough space for storage, etc. Even if there is always a thing that is not normally needed, it will impair the economy of the ship. .

Further, in the case of the hanging fitting 7, conventionally, since the lifting levers 11 and 12 and the lifting piece 13 of the gas turbine 4 are connected by the bolts and the nuts 14, it is troublesome and can be connected more easily. A device was desired.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a trolley device which can be carried out and carried in from the outside without using a temporary structure, and can be easily attached to and detached from an object to be lifted. An object is to provide a hanging metal fitting that can be made.

[0008]

In order to achieve the above object, one end is detachably supported by another fixed rail or a ceiling, and is horizontally rotated at a rotation center at a position of a predetermined length from the other end toward one end. A rotating rail that is freely supported from the ceiling, a roller that is provided above the other end of the rotating rail and has the same axial direction as the length direction of the rotating rail, and a rotating rail that is provided on the ceiling and that rotates the rotating rail. A guide rail that rotatably restrains the roller in a vertical direction with a radius of the predetermined length from the center.

Also, a horizontal beam suspended on the trolley, a threaded rod having one end threaded to the left and the other end threaded to the right, and provided with a rotating handle at either end, A bearing provided on the horizontal beam to rotatably support the screw rod in parallel with the horizontal beam, and one end that is screwed into the threaded portions at both ends of the screw rod and a pin attached to the other end. Levers and stoppers for stopping the lifting levers attached to the bearings and rotating with the rotation of the screw rod at a vertical position and at a predetermined position, and the pins at the other ends of the respective lifting levers are in the axial direction. Are in the same direction as the threaded rods and are arranged so as to face each other inward or separate from each other outward.

[0010]

[Operation] After the object to be hoisted is hoisted by the fixed rail or the trolley at the position of the turning rail, the trolley is moved to the turning center of the turning rail and another fixed rail connecting one end of the turning rail. Alternatively, the object can be carried out outdoors by releasing it from the ceiling, turning it around the turning center, taking one end out of the room, and moving the trolley in this state. When carried out outdoors, the rotation rail is supported by the rotation center and the roller at the other end, and the roller at the other end is constrained in the vertical direction, so that it functions as a support point and can support the load. Further, since the roller at the other end is rotatably supported, the rotating rail is smoothly rotated.

When the rotating handle is turned, the lifting lever screwed with the threaded portions at both ends of the threaded rod rotates together with the threaded rod,
When it reaches the vertical position, it is stopped by the stopper and only the screw rod rotates. This causes the lifting levers at both ends to move inward or outward relative to each other in a vertical state. Since the pin provided at the tip of each lifting lever also moves inward or outward, provide a lifting piece for the object to be lifted at this pin, and make a hole in the lifting piece at the position corresponding to the pin. For example, a pin can be fitted in this hole. If you turn the rotary handle in the opposite direction, the pin will come out of the pin hole. Then, the lifting lever rotates together with the screw rod and hits a stopper provided at a predetermined position to stop there. Thus, when the object to be lifted is not connected to the lifting piece, the lifting lever is rotated to a predetermined position, and when the object to be lifted is connected to the hanging metal fitting, it is rotated to a vertical position, Subsequently, the operation of fitting the pin into the pin hole can be continuously performed. Even when it is removed from the pin hole, it is possible to continuously perform the removing operation and the operation of rotating to a predetermined position.
