Abstract
The utility model provides an inside cooler of a coal cutter cutting portion. The inside cooler is mainly characterized in that four heat dissipation water pipes are sleeved on a connection part, two ends of each heat dissipation water pipe are connected with water pipes in a welded mode, two ends of the connection piece are connected with a seal shaft and a flange in a welded mode, and the seal shaft and the flange are respectively provided with an O-shaped seal ring. A hinge bolt, a combination gasket and a hinge piece are installed on one side of the seal shaft, a rubber pipe is installed on the hinge piece, a hinge piece, a hinge bolt and a combination gasket are installed at a position on one side of the flange similarly, and the position is a water inlet. A rubber pipe is installed on the hinge piece of the flange, and cooling water enters into the heat dissipation water pipes through the rubber pipe. The whole set of inside cooler is firmly fixed inside a rocker arm shell. The inside cooler has the advantages that cooling devices directly cool gear wheel lubricating oil, thermal conductivity is increased, each cool device is composed of four cooling water pipes, and the thermal conductivity is greatly improved. Two streams of cooling water in two cooling devices finally combined into one stream to be ejected in an outside-sprayed mode after the cooling water cools inner cavities, and therefore, on one hand, the function of dust falling is achieved, and on the other hand, waste of water resources is avoided.
Description
Technical field
The utility model relates to a kind of large power electric shearer, particularly a kind of internal cooler of winning machine cutting part gear transmission cavity.
Background technique
The most mode that adopts the housing water jacket to force cooling of the cutting portion of present domestic large power electric shearer, although this cooling can be played the effect of atomizing de-dusting, but the oil sump effect is but very little in the cooling gear cavity, because the winning machine cutting part housing is 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 always very high main cause of large power electric shearer cutting portion gear cavity inside temperature.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of novel, safety, and reliability is high, the cooling unit that heat-conducting effect is splendid.This cooling unit is contained in the winning machine cutting part gear cavity, and the cooling by cooling water reduces the oil temperature in the gear.
The purpose of this utility model is achieved in that and comprises heat dissipating pipe, articulated elements, hinge bolt, sealing axle bed, link, it is characterized in that, four heat dissipation pipes are enclosed within on the link, two ends and water pipe welding, two ends welded seal axle and the flange of link, seal shaft and flange are equipped with O-ring seals separately, side at seal shaft is equipped with hinge bolt and combination mat and articulated elements, sebific duct is housed on the articulated elements, is water outlet herein, and cooling water flows out from sebific duct.Side at flange is equipped with articulated elements and hinge bolt and combination mat too, is water intake herein.Sebific duct is housed on the articulated body, and cooling water enters in the heat dissipating pipe from sebific duct.The cooler integral installation is in the rocker arm of coal mining machine housing, and a side is closed with bolt and packing ring handle, and opposite side is fixed in the rocking arm shell a whole set of cooler with block and retainer ring spacing firmly.
Its principle is: after cooling water is through the water valve allocation block, enter respectively direct cooling oil sump in two groups of cooling units by articulated elements, then two groups of cooling waters import one and enter in the cutting portion inner sprayer unit, and inner sprayer unit links with the form ejection of external spraying by pipeline and cylinder.Be divided into altogether two groups, be installed in respectively up and down two ends of cutting portion cavity.
Advantage of the present utility model is:
1, cooling unit directly cools off the gear lubricant thermal conductivity increases, and every group of cooling unit be comprised of four water-cooling tubes, and spiral heat dissipation sheet (spiral heat dissipation sheet and water-cooling tube are welded into one) is all arranged on the every cooling tube, has greatly improved thermal conductivity; 2, final one form with external spraying that imports sprays behind two strands of complete inner chambers of water quench in the two assembling radiator coolers, and the one, played the effect of depositing dust, the 2nd, the waste that must exempt from water resources.

Embodiment
Below in conjunction with concrete accompanying drawing the present embodiment is described further
As shown in Figure 1, four heat dissipation pipes 7 are enclosed within on the link 6 then two ends and water pipe welding, the effect of link 6 is to support and fix four heat dissipation pipes, at the two ends of link 6 at seal shaft 4 and the flange 8 of burn-oning.The effect of seal shaft 4 is after integral body is positioned on the cutting portion, and seal shaft plays the effect of location and sealing, and the location is fixing single unit system, and sealing is to prevent the gear cavity leakage of oil.The effect of flange 8 is the same with the effect of seal shaft, and packaged O-ring seals 5 and the O-ring seals 9 that has separately of seal shaft and flange is equipped with hinge bolt 1, combination mat 2, articulated elements 3 in a side of seal shaft 4, is water outlet herein.One side of seal shaft has tapped hole, and hinge bolt 1 puts together on combination mat 2 and articulated elements 3 on the seal shaft, and sebific duct is housed on the articulated elements, and cooling water flows out from sebific duct.Side at flange 8 is equipped with articulated elements 3B, hinge bolt 13, combination mat 2 too, is water intake herein.One side of flange 8 has tapped hole, and hinge bolt 13 is with combination mat 2, and articulated elements 3B puts together on the flange piece, and sebific duct is housed on the articulated body, and cooling water enters in the heat dissipating pipe from sebific duct.The cooler integral installation is in the rocker arm of coal mining machine housing, and closing, opposite side is spacing with block 14 and back-up ring 15 with bolt 10, packing ring 11 for a side.A whole set of cooler is fixed in the rocking arm shell firmly.The spiral heat dissipation sheet is all arranged on the every cooling tube, and spiral heat dissipation sheet and water-cooling tube are welded into one.
