Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frost conveying device used for defrosting a ceiling hairpin coil provided in a freezing or refrigerating warehouse.

[0002]

2. Description of the Related Art Hot gas defrost (hereinafter referred to as defrost) of a conventional ceiling hairpin coil is carried out by moving a baggage in a freezing or refrigerating warehouse or by placing a sheet on the baggage. For the straight line, a mobile automatic defroster is used.

[0003]

In the conventional defrosting work for defrosting a ceiling hairpin coil, defrosting in a refrigerator can be done by hot gas only by operating a valve, but a large amount of defrosted frost is removed. There is a problem that the work up to putting it in the bucket is laborious and troublesome, so it would be good to improve here.

The present invention is designed to remove a large amount of defrosted defrost from the ceiling hairpin coil onto the sheet of the conveyor,
It is an object of the present invention to provide a defrosting frost transfer device for the de-frosting of an up-coil to the ceiling in which the sheet is dropped into the bucket while moving the sheet toward the passage using a trolley, chain block, forklift, or the like.

[0005]

When setting the suspension bracket, remove the upper rail, put it in place, and then stop the upper rail.

An intermediate vehicle and a seat are hung between the seats with a vehicle strap.

[0007] Further, after the intermediate sheaves of the seat are sequentially inserted into the rails, the ropes on both sides of the seat are pulled through the first rope sheave and the second rope sheave of the suspension metal fitting to pull the sheave rope. Make it strong and then hang it on the rope hook for easy removal.

Further, since the seat surface is to be hung by the intermediate portion carriage, the seat portion should be higher than the horizontal portion in the middle portion.

A sheet should be prepared with a width sufficient to cover the ceiling hairpin coil span. To prevent the sheet from breaking even if the defrosted frost falls, the reinforcement rope is sewn in sufficiently so that a hook or ring for tying the string is placed in the middle of the sheet.

When defrosting is not required, the sheet should be removed and dried to determine the storage location, and the rope should be prepared if necessary. The frost carrier and rails will be permanently installed in the refrigerated / refrigerated warehouse. Also, remove the wire messenger for guard to secure the head space for defrosting the ceiling hairpin coil, defrost the hot gas, and after completion, install the wire messenger for guard permanently between the walls to transport frost. It will be a protective device for equipment, ceiling hairpin coils, lighting equipment, piping, etc.

[0011]

In the frost conveying device configured as described above, a large amount of frost defrosted from the ceiling hairpin coil falls on the sheet surface, so that slack occurs and the frost is biased in this direction and the sheet is cut. The slack is reduced by connecting and pulling the intermediate vehicle from the middle of the seat with the vehicle straps.

The load on the hanging bracket and the rail bracket is alleviated, and it is easy to travel and works to maintain stable rotation of the vehicle.
