The internal cooler device comprises a liquid feeding hinged bolt, a liquid feeding joint body, a sealing shaft, connecting blocks, a flange block, a liquid discharging joint body and a liquid discharging hinged bolt, wherein one end part of the sealing shaft is in screwed connection with the liquid feeding hinged bolt; the liquid feeding joint body is arranged on the liquid feeding hinged bolt; the other end part of the sealing shaft is fixedly provided with the connecting block; one end part of the flange block is in screwed connected with the liquid discharging hinged bolt; the liquid discharging joint body is arranged on the liquid discharging hinged bolt; the other end part of the flange block is fixedly provided with another connecting block; a cooling pipe is fixed between the two connecting blocks; and the outer wall of the cooling pipe between the two connecting blocks is provided with radiating fins.. The internal cooler device disclosed by the utility model has the advantages of simple structure, safety in use, high reliability, good heat-conducting effect and the like.
Description
Technical field
The utility model relates to the interior cooling unit in a kind of large power, electrically haulage shearer cutting portion gear transmission chamber.
Background technique
At present; The most mode that adopts the housing water jacket to force cooling of the cutting portion of domestic large power, electrically haulage shearer; Though this cooling can be played the effect of atomizing de-dusting, the cooling gear cavity in the oil sump effect but very little because the winning machine cutting part housing is a Cast Steel; To consider its security intensity during design; So the inwall minimum safe thickness of the inwall of housing water jacket and gear cavity is more than the 50mm, and the heat-conducting effect of 50mm thickness is not very desirable, so this also is the very high always main cause of large power, electrically haulage shearer cutting portion gear cavity inside temperature.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the existing technology, and the intercooler device in the winning machine cutting part gear transmission chamber of a kind of safety, reliability height, good heat conduction effect is provided.
The technological scheme that provides according to the utility model; The intercooler device in said winning machine cutting part gear transmission chamber; Comprise feed liquor hinge bolt, liquid inlet joint body, seal shaft, contiguous block, flange piece, fluid fittings body and fluid hinge bolt; End at seal shaft is bolted with the feed liquor hinge bolt, and the liquid inlet joint body is installed on the feed liquor hinge bolt, is fixed with contiguous block in the other end of seal shaft; End at the flange piece is bolted with the fluid hinge bolt; The fluid fittings body is installed on the fluid hinge bolt; Be fixed with another contiguous block in the other end of flange piece; Between two contiguous blocks, be fixed with cooling tube, on the outer wall of the cooling tube between two contiguous blocks, be provided with radiating fin; The opening of being offered in said feed liquor hinge bolt, liquid inlet joint body, seal shaft, cooling tube, flange piece, fluid fittings body and the fluid hinge bolt is breakthrough status.
Described radiating fin is a helical.Described cooling tube has four.
The utlity model has simple in structure, safe in utilization, reliability is high and advantage such as good heat conduction effect.
Description of drawings
Fig. 1 is the overall structure schematic representation of the utility model.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure, the utility model mainly is made up of parts such as liquid hinge bolt 1, liquid inlet joint body 2, seal shaft 3, contiguous block 4, flange piece 5, fluid fittings body 6, fluid hinge bolt 7, cooling tube 8 and radiating fins 9.
The intercooler device in this winning machine cutting part gear transmission chamber; Comprise feed liquor hinge bolt 1, liquid inlet joint body 2, seal shaft 3, contiguous block 4, flange piece 5, fluid fittings body 6 and fluid hinge bolt 7; End at seal shaft 3 is bolted with feed liquor hinge bolt 1; Liquid inlet joint body 2 is installed on feed liquor hinge bolt 1, is fixed with contiguous block 4 in the other end of seal shaft 3; End at flange piece 5 is bolted with fluid hinge bolt 7; Fluid fittings body 6 is installed on fluid hinge bolt 7; Be fixed with another contiguous block 4 in the other end of flange piece 5; Between two contiguous blocks 4, be fixed with cooling tube 8, on the outer wall of the cooling tube between two contiguous blocks 48, be provided with radiating fin 9; The openings of being offered in said feed liquor hinge bolt 1, liquid inlet joint body 2, seal shaft 3, cooling tube 8, flange piece 5, fluid fittings body 6 and the fluid hinge bolt 7 are breakthrough status.
Described radiating fin 9 is a helical.Described cooling tube 8 has four.The two end part of cooling tube 8 are screwed onto in the corresponding contiguous block 4.
The utility model is after cooling water is through the water valve allocation block; Through entering into four cooling tubes 8 behind liquid inlet joint body 2, feed liquor hinge bolt 1, the seal shaft 3 respectively; Cooling water in four cooling tubes 8 imports one and gets in cutting portion inner sprayer unit then, and inner sprayer unit sprays through the form that pipeline and cylinder link with external spraying.Cooling tube 8 directly cools off gear lubricant, and thermal conductivity increases, and on the every cooling tube 8 spiral heat dissipation fin 9 is arranged all, has improved thermal conductivity greatly.
