Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a frost removal sweeper for removing frost adhering to freezing pipes in a cold storage warehouse or the like.

[Conventional technology]

In cold storage warehouses and the like, as shown in Fig. 6, a plurality of cross beams 2 are suspended from the ceiling 1, and freezing pipes 3 are placed on these cross beams 2 to provide long-length pipes. If frost builds up on the freezing tube 3 during operation for a period of time, the cooling efficiency will decrease, so workers have to remove the frost with a broom or the like.

[Problem that the invention attempts to solve]

However, because of the extremely low temperatures in cold storage warehouses, the working environment is poor and the work is difficult and inefficient.

Therefore, the present invention aims to improve efficiency by automating the defrosting work of freezing tubes.

[Means for solving the problem] In order to achieve the above object, the present invention is characterized in that a running body is provided with an upper running wheel that rolls on the upper edge of the upper fin that stands upright at the top of the longitudinal direction of the refrigeration tube, and a lower running wheel that rolls on the underside of the refrigeration tube between two lower fins provided at the bottom of the longitudinal direction of the refrigeration tube, and a defrosting brush is provided on the running body to wipe the surfaces of the refrigeration tube and each fin.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. In the figure, the same elements as those in FIG. 6 are given the same reference numerals and explained.

The freezing tube 3 has one upper fin 3a standing upright at the upper part in the longitudinal direction, and two lower fins 3b, 3b are provided at the lower part in the longitudinal direction, spaced apart from each other in an eight-shaped cross-section. The freezing pipe 3 is supported by the freezing pipe 2 and is piped to the ceiling of the frozen warehouse, and the freezing pipe 3 is provided with a defrost sweeper 4.

The defrost sweeper 4 includes defrost brushes 6, 6 for wiping off both sides of the freezing pipe 3 and each fin 3a, 3b, 3b, and defrost brushes 7, 7 for wiping between the lower fins 3b, 3b on the running body 5. It is made up of.

The running body 5 has upper running wheels 9, 9 mounted on an upper bracket 8 that roll on the upper edge of the upper fin 3a of the freezing tube 3.
and a flanged guide ring 10, 10 are rotatably supported, and the upper bracket 8 is provided with lower brackets 11, 11 that wrap around from the side surface of the freezing tube 3 to the lower side of the lower fin 3b, and both lower brackets 11,
11 rotatably supports a lower running wheel 12 that rolls on the lower surface of the freezing tube 3 between the lower fins 3b, 3b, and the freezing tube 3 and each fin 3 are mounted on the upper bracket 8.
Defrost brushes 6, 6 for wiping both sides of the plates 7a, 3b, 3b are provided on the lower brackets 11, 11, and defrost brushes 7, 7 for wiping between the lower fins 3b, 3b are provided on the lower brackets 11, 11. 1
It is fixed to the sides of 1 and 11 with screws.

When the defrost sweeper 4 configured in this way is moved in the longitudinal direction of the freezing tube 3, the defrost brushes 6, 6
And the defrosting brushes 7, 7 are connected to the freezing tube 3 and each fin 3.
Perform defrosting work by wiping the surfaces of a, 3b, and 3b.

Further, the lower bracket 11 is provided with wheels 13 whose outer periphery protrudes beyond the lower end of the lower bracket 11, and when the defroster sweeper 4 moves, the wheels 13 roll on the crossbeams 2 and move downward. The ring 12 lifts the freezing tube 3 and separates the lower fins 3b, 3b and the cross beam 2 to prevent interference between the lower brackets 11, 11 and the cross beam 2, thereby facilitating movement of the defroster sweeper 4. .

In cold storage warehouses, etc., the freezing pipes 3 are often arranged in two stages, upper and lower, as shown in Fig. 4.
In this case, the defrost sweeper 4 placed on the left in the diagram of the upper freezing tube 3 and the lower freezing tube 3
The frost remover sweeper 4 placed on the right side of the rope 1
4 and 14 are connected via pulleys 15 and 15, respectively, the upper defrost sweeper 4 and the lower defrost sweeper 5 can perform defrosting work in opposite directions to each other, and as shown in FIG. In addition, a plurality of freezing tubes 3 are placed in parallel on the crossbeam 2, and the ends of each freezing tube 3 are connected by a U-shaped tube 16, so that the frost formed on each freezing tube 3 is It is also possible to connect a plurality of sweepers 4 using connecting plates 17, 17 and move them.

As described above, according to the defrost sweeper of the present invention,
It can automate the defrosting work of frozen pipes in cold storage warehouses, etc., which previously required manual labor, greatly increasing work efficiency.
It becomes possible to improve cooling efficiency.

[Effect of idea]

As described above, the present invention is equipped with a defrosting brush that wipes the surface of the freezing tube on the traveling body that runs through the freezing tube, so the defrosting work can be automated, greatly increasing work efficiency, and improving cooling efficiency. You can improve your performance.
