武漢鑫文豐機(jī)械有限公司
武漢鑫文豐機(jī)械有限公司是一家專業(yè)生產(chǎn)礦山機(jī)械設(shè)備的公司。具有先進(jìn)的鑿巖機(jī)具研制開(kāi)發(fā)中心，擁有一支實(shí)力雄厚的科研開(kāi)發(fā)隊(duì)伍，近幾年來(lái)，研制的YDT31型新型電動(dòng)鑿巖機(jī)專利產(chǎn)品，填補(bǔ)了我國(guó)鑿巖機(jī)械中一次能量轉(zhuǎn)換的空白，冶金部科技成果鑒定會(huì)鑒定為“達(dá)到國(guó)際先進(jìn)水平，是對(duì)我國(guó)電動(dòng)鑿巖機(jī)研制方面一個(gè)新的貢獻(xiàn)”。在致密花崗巖（f=14～16,σb=140～160MPa）中鑿速達(dá)180～280毫米/分（鉆頭直徑36mm），比一般相似機(jī)型的鑿速提高30%，較目前小型氣動(dòng)鑿巖機(jī)提高70%，該機(jī)的能量利用率達(dá)53.1%,為現(xiàn)有小型氣動(dòng)鑿巖機(jī)能量利用率（7.7%）的七倍，按每臺(tái)年工作300天*5小時(shí)計(jì)，節(jié)電11820度，以1000臺(tái)計(jì)，年節(jié)電1182萬(wàn)度，節(jié)電效益為768.3萬(wàn)元/年，不需壓風(fēng)設(shè)備和輸風(fēng)管道，借助柴油發(fā)電機(jī)，在無(wú)電區(qū)域也能正常工作，節(jié)約大量基本建設(shè)資金，確保人身、場(chǎng)區(qū)、設(shè)備的安全作業(yè)。由此開(kāi)發(fā)的系列產(chǎn)品手持式、機(jī)動(dòng)式、電液式、臺(tái)車式等鑿巖機(jī)械，廣泛用于修筑公路、鐵路、機(jī)場(chǎng)跑道、地質(zhì)勘探、金屬和非金屬礦藏開(kāi)采、國(guó)防工程等領(lǐng)域。WuhanXinwenfengMachineyCo.,Ltdisanewcompanytomajormanufacturetheminemachineryequipment.IthasanadvancedresearchcenterandaR&Dteamwithrichexperiencewithanefforttothedevelopmentandtestofrockdrillandtools.Inrecentyears,thecompanyhassucceededindevelopingthepatentproduct,YDT31NewTypePowerfulElectricRockDrill,whichhaspassedtheScience&TechnologyAchievementsExpertiseOrganizedbytheMinistryofMetallurgyIndustry,andregardedas“havingachievedtheintemationaladvancedlevelinthefieldandmadeanewcontributiontothedevelopmentofelectricrockdrillinourcountry”.Fordrillingindensegranite(f=14～16,σb=140～160MPa),thepenetrationrateisupto180～280mm/min(bitdiameter36mm),whichis30%fasterthanthatofthesimilarproducts,70%fastertheordinarysmallpneumaticrockdrills.Theenergyutilizationefficiencyisupto53.1%,whichis7timesasthatofthesmallpneumaticrockdrill(7.7%).Bycalculationofoperatingtimeas300days×5hoursforayearperdrillset,itcansaveelectricityby11820kilowatt-hours.Furthermore,bycalculationfor1000duillsets,thiscansaveelectricityupto11.82millionkilowatt-hoursperyear.Theresultingprofitonelectricityeconomizationis7.683millionyuanRMBperyear.Itneedsneitheraircompressingfacilitiesnorpipelines,andcanoperatenormallyeveninsitewithoutelectricitybymeansofdieselengineTherefore,
