Abstract
The invention discloses a planetary mechanism cooling drum of a cutting unit of a coal mining machine. The planetary mechanism cooling drum comprises a drum and a copper cooling pipe. The copper cooling pipe is fixedly arranged on the inner wall of the drum through a supporting framework. The two ends of the copper cooling pipe are respectively provided with a copper pipe welding joint. Each copper pipe welding joint is communicated with a rubber pipe through a quick joint. The copper cooling pipe is arranged between the inner wall of the drum and the inner gear ring of a planetary mechanism. One of the two rubber pipes at the two ends of the copper cooling pipes is used for being communicated with a spray water outlet in the cutting unit, and the other one of the two rubber pipes is used for being communicated with a spray joint outside the drum. The planetary mechanism cooling drum of the cutting unit of the coal mining machine provided by the invention has the advantages that the function and the strength of the cutting unit can be guaranteed, the planetary mechanism can be cooled and the damages and the accidents caused by high temperature to components of the planetary mechanism are reduced.
Description
Technical field
The present invention relates to the cooling of slicing portion of drum shearer planetary mechanism transmission, relate in particular to a kind of winning machine cutting part planetary mechanism chilling roll.
Background technique
At present, slicing portion of drum shearer planetary mechanism place is because the condition restriction such as space are not established cooling unit basically.Because the cylindrical shell of cutting drum has sealed the cutting portion planetary mechanism, be not easy heat radiation, thereby cause the planetary mechanism inside temperature too high, have a strong impact on the working life of planetary mechanism gear and bearing, cause component to damage, even likely bring inestimable consequence.Usually need to select imported bearing to extend its working life, greatly increased cost, and can not thoroughly deal with problems.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of winning machine cutting part planetary mechanism chilling roll, under existing spatial constraints condition, can carry out the winning machine cutting part planetary mechanism coolingly, reduce the infringement and the accident that component are caused due to high temperature.
Technological scheme: for achieving the above object, the technical solution used in the present invention is:
Winning machine cutting part planetary mechanism chilling roll, comprise cylinder and cooling copper tube, and described cooling copper tube is fixed on the inwall of cylinder by support frame; The two ends of described cooling copper tube are provided with a copper pipe welded joint, and each copper pipe welded joint all is connected with one section sebific duct by a quick union; Described cooling copper tube is arranged between the inwall and planetary mechanism ring gear of cylinder; Two sections sebific ducts at described cooling copper tube two ends, wherein one section sebific duct is for being communicated with cutting portion internal spraying water outlet, and another section sebific duct is for being communicated with cylinder external spraying joint.
In said structure, described cutting portion internal spraying water outlet and cylinder external spraying joint are existing mechanism from band structure.In existing structure, the water flowed out from cutting portion internal spraying water outlet directly enters cylinder external spraying joint, and sprays by nozzle purposes such as realizing dedusting.After adopting this programme, the moisture flowed out from cutting portion internal spraying water outlet becomes two-way, and a road still directly enters cylinder external spraying joint, and another road enters cylinder external spraying joint after cooling copper tube again, finally by nozzle, sprays; And the water of process cooling copper tube has been taken away the part heat of cylinder inside, realized planetary mechanism is carried out to cooling purpose; Certainly in this process, the water flowed out from cutting portion internal spraying water outlet should be cooling water.
During work, the auxiliary parts that add of the present invention, all in company with the cylinder associated movement, are totally independent of among cylinder; In working procedure, do not adopt other auxiliary water supply equipment, simple in structure, it is convenient to realize; On the function of cutting portion and intensity, all without impact, and cooling segment is arranged between cylinder and planetary mechanism ring gear, in enclosed space, not fragile.
Preferably, on the wheel hub of described cylinder, by screw, be fixed with the joint fixed plate, described quick union and copper pipe welded joint all are fixed on the joint fixed plate by worm structure; Described support frame is fixed by screws on the inwall of cylinder.Use screw and be threaded and realize detachably facilitating I&M.
Preferably, described cooling copper tube dish cloth becomes waveform configuration.To increase the distribution area of cooling copper copper pipe in cylinder, improve cooling effectiveness, in order to realize that planetary mechanism is carried out to cooling specific aim, cooling copper tube should be distributed in the right opposite of planetary mechanism as much as possible.Certainly, need to be according to the size of the spatial relation choose reasonable cooling unit of size, cutting portion planetary mechanism and the cylinder of cutting portion planetary mechanism, quantity of choose reasonable cooling copper tube etc.
Beneficial effect: winning machine cutting part planetary mechanism chilling roll provided by the invention, can in the function and intensity that guarantee cutting portion, to planetary mechanism, provide cooling, reduce the infringement and the accident that cutting portion planetary mechanism component are caused due to high temperature.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Be illustrated in figure 1 a kind of winning machine cutting part planetary mechanism chilling roll, comprise cylinder 9 and cooling copper tube 3, described cooling copper tube 3 is fixed on the inwall of cylinder 9 by support frame 2; The two ends of described cooling copper tube 3 are provided with a copper pipe welded joint 4, and each copper pipe welded joint 4 all is connected with one section sebific duct 9 by a quick union 6; Described cooling copper tube 3 is arranged between the inwall and planetary mechanism ring gear of cylinder 9; Two sections sebific ducts 8 at described cooling copper tube 3 two ends, wherein one section sebific duct 8 is for being communicated with cutting portion internal spraying water outlet, and another section sebific duct 8 is for being communicated with cylinder external spraying joint.
During work, the water flowed out from cutting portion internal spraying water outlet just is divided into two-way, and a road directly enters cylinder external spraying joint, and another road enters cylinder external spraying joint after cooling copper tube 3, then sprays by nozzle purposes such as realizing dedusting; And the water of process cooling copper tube 3 has been taken away the part heat of cylinder 9 inside, realized planetary mechanism is carried out to cooling purpose; Certainly in this process, the water flowed out from cutting portion internal spraying water outlet should be cooling water.
Be fixed with joint fixed plate 5 by screw on the wheel hub of described cylinder 9, described quick union 6 and copper pipe welded joint 4 are threaded connection structure and are fixed on joint fixed plate 5.Described support frame 2 is fixed on the inwall of cylinder 9 by screw 1.Described cooling copper tube 3 dish cloth become waveform configuration.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
