EKG Productive Excavators yog mining tracked tsheb siv hauv kev txhim kho thiab thauj cov pob zeb, pob zeb thiab mine ua haujlwm. Tsis tas li ntawd, lub tshuab ua haujlwm thaum lub sijhawm thauj khoom ntawm cov khoom thauj khoom thiab cov chaw khaws khoom, thiab koom nrog kev tsim khoom. Cov chav nyob yog tsim los rau hauv tus account lub peculiarities ntawm climatic cheeb tsam, lawv muaj mechanisms nyob rau hauv daim ntawv ntawm tiav technologies blocks, uas ua rau nws muaj peev xwm kho cov cuab yeej nyob rau hauv ib tug tag nrho txoj kev.

Devices thiab lub ntsiab mechanisms

EKG excavators tau nruab nrog lub cev, lub voj voog, ib xub, lub thoob mining ntawm ntau qhov ntau thiab tsawg thiab lem. Tsis tas li ntawd, ib qho qis dua thiab ob-theem khib yog muab. Lub tshuab mining yog ua los ntawm cov hlau muaj zog, ua haujlwm hauv ntau yam kev nyab xeeb.

Cov ntsiab lus tseem ceeb ntawm lub thoob ua haujlwm suav nrog pem hauv ntej thiab nram qab phab ntsa, hauv qab, sab ntsiab lus thiab rocker. Lub cev cuam tshuam nrog lwm qhov chaw ua haujlwm los ntawm cov ntiv tes tshwj xeeb. Cov hlau kov dhau los ntawm qhov muab txuas rau hauv lub boom, uas yog nruab nrog lub siab blocks thiab winch mechanism. Nyob rau lub turntable mounted tsis tsuas yogboom, tab sis kuj lub dynamic chav tsev, hluav taws xob Circuit Court, lub cev qhov chaw thiab racks. Tus neeg tsav tsheb lub tsheb ua tiav lub tshuab sab nrauv.

Ntse

Hauv qab no yog qhov tsis muaj ntawm cov phiaj xwm kev ua haujlwm uas ECG excavators muaj:

• ntev/dav/qhov siab ntawm lub thoob - 2450/2190/2560 mm nrog ib tug loj ntawm 9.9 tons;
• zoo ib yam ntawm lub turntable - 8100/5000/1200 mm nrog ib tug luj ntawm 18.9 tons;
• thoob ntim yog 5.2 cubic meters;
• qhov siab thiab khawb lub vojvoog - 10.3 / 14.5 meters;
• ua haujlwm hnyav - 196 tons;
• dimensions ntawm qis ncej hnyav 10.5 tons - 3000/3000/1680 mm;
• zoo ib yam li tus ncej uas hnyav 5.4 tons - 5500/750/1000 mm.

Tus neeg tsav tsheb lub cab hnyav hnyav 1.1 tons, nws ntev yog 2.36 meters, thiab nws qhov dav thiab qhov siab yog 1.35 thiab 2.76 meters, raws li.

Lub nres chav tsev ntawm lub siab thiab lub tshuab teb, nrog rau lub winch, ua haujlwm vim cov cua ntws los ntawm compressor. Lub undercarriage yog nruab nrog ib tug hydraulic system uas kho lub lag luam ntawm lub clutch hloov ntawm cov lem thiab mus ncig teb chaws brakes.

tsob nroj muaj zog

Lub EKG mining excavator yog nruab nrog lub laub, nqa, tig thiab mus ncig. Kev qhib lub thoob yog nqa tawm los ntawm kev siv hluav taws xob los ntawm DC motors. Lwm cov khoom pabcuam yog siv los ntawm cov motors sib txawv. Cov nodes tseem ceeb tau txais lub zog los ntawm kev hloov dua siab tshiab generators thiab step-down transformers.

Qhov tseem ceeb tshaj plaws uas ua kom cov cuab yeej ua haujlwm yoggenerator lub cev muaj zog nrog thyristor excitation. Nws cov ntsiab lus tseem ceeb yog:

• transformer kev ua tau zoo - 160 kVA;
• Lub npe lub zog ntawm chav tsev network yog 800 kW, lossis ib txhiab horsepower.

Lub tshuab hluav taws xob nyob tom qab.

Kev hloov kho ntawm lub excavator EKG 5A

Cov tshuab muaj zog no yog siv hauv kev lag luam mining thiab kev lag luam. Lawv pab txhawb kev ua haujlwm ntawm cov tuam txhab metallurgical, thee mining chaw thiab kev tsim kho kev lag luam. Excavators muaj lub zog siab, kev tswj kom muaj zog thiab kev tswj xyuas siab.

Dhau li ntawm ECG qauv 5A, muaj ntau qhov kev hloov pauv zoo sib xws, sib txawv hauv qhov ntsuas tsis tseem ceeb:

1. Hloov kho 5V muaj lub tshuab fais fab nrog lub peev xwm ntawm ob puas thiab tsib caug kilowatts. Muaj peev xwm ua haujlwm ntawm pob zeb yam tsis tau npaj ua ntej, nruab nrog lub thoob tshwj xeeb nrog rauj es tsis txhob siv cov hniav ib txwm siv.
2. Version 5D yog mining crawler excavator, cov tsis zoo ib yam li cov qauv dhau los. Nws txawv tsuas yog nyob rau hauv lub xub ntiag ntawm ib tug ua ke diesel cav thiab ib tug hluav taws xob lub cev muaj zog. Nws muaj peev xwm thauj cov tsheb thauj khoom ntawm nws tus kheej.
3. 5U - cov cuab yeej muaj zog uas muaj peev xwm hla dhau trenches, ua cov ledges, thiab ua haujlwm thauj khoom. Lub excavator tau nruab nrog lub tsev ua haujlwm yooj yim nrog kev pom zoo thiab cov ntaub ntawv tswj hwm.
4. Model EKG-4, 6 A. Thawj lub tshuab ntawm pawg no tau tsim tawm ntawm Uralmash. Lawv tau ua tiav los txog tam sim nomuaj nuj nqi, nruab nrog 5.2 cubic meter thoob thiab 250 kW lub cev muaj zog.

Excavator EKG-10

Ntawm cov qauv tsim ntawm cov cuab yeej ntawm cov koob no, cov ntsiab lus hauv qab no yuav tsum tau qhia:

• thoob nqa tau tsis siv neeg lub zog ruaj khov;
• khoom siv yog nruab nrog lub winch nrog lub lifting boom, yooj yim kho thiab tu lub tsev;
• brake system ntawm cov chav tseem ceeb - khau hom nrog pneumatics;
• Npaj cam khwb cia tsim thoob;
• dawb-poob lub hauv qab tshem tawm kev sib cuag nrog tus kov;
• Rack thiab pinion siab system suav nrog txhua qhov kev sib tw welded thiab kov nrog ob kab kab;
• qhov kev tsim no txhim kho kev tuav cov pob zeb nyuaj;
• cov khoom siv cua tshwj xeeb tsim cov cua siab hauv lub thawv;
• Qhov tseem ceeb ntawm lub tshuab yog ua los ntawm cov hlau alloy.

Txo kev tiv thaiv kev saib xyuas thiab kho tus nqi nrog kev siv lub tshuab lubrication zoo.

txiaj ntsig

EKG excavators yog nruab nrog ob-khiav undercarriage nrog ib tug cais tsav rau txhua txoj kev. Qhov no ua rau nws ua tau kom tau txais kev txhawb nqa qis ntawm cov khoom siv, uas ua rau kom muaj kev ruaj ntseg ntawm kev sib dhos thiab kev hloov kho ntawm qhov nro ntawm cov lem. Embedded hydraulic cylinders thiab yuam cua ua pa pab txhawb ntxiv dynamics thaum lub sijhawm ua haujlwm ntawm chav tsev. Lub ntsiab mechanisms ntawm lub excavator yog nruab nrogtus kheej adjustable fais tsav.

Lub tsev ntawm lub cuab yeej muaj cov cuab yeej siv tau yooj yim. Nws muab lub suab nrov thiab plua plav rwb thaiv tsev nyob rau hauv daim ntawv ntawm cov partitions tshwj xeeb. Tsis tas li ntawd, qhov chaw ua haujlwm yog nruab nrog cua txias, muaj ib qho chaw sab hauv thiab muaj cua sov. Lub vaj huam sib luag nyob ruaj ruaj tso cai rau koj los kho tus neeg teb xov tooj lub rooj sai sai. Cov yam ntxwv ntawm cov txheej txheem no suav nrog qhov tsis muaj lub gearbox, vim tias qhov kev txav mus los hauv ib hom kev kub ceev.

Ntu 8&

Lub EKG excavator, cov yam ntxwv ntawm peb yuav xav txog hauv qab no, yog nruab nrog lub tshuab hluav taws xob nrog lub peev xwm ntawm tsib puas thiab nees nkaum kilowatts. Qhov loj ntawm cov cuab yeej loj no yog 373 tons. Lub tshuab muaj peev xwm nce siab tshaj kaum degrees, tswj txhua qhov kev khiav haujlwm.

Ntawm niaj hnub version ntawm cov koob no yog ib qho excavator nyob rau hauv lub cim EKG-8-US. Nws yog txawm peem rau nrog ib tug ntev boom, ua hauj lwm nyob rau hauv lub rooj ntev zaum thiab nyob rau hauv high heights, thiab kuj yog yoog rau kev thauj khoom mus rau cov tsheb thauj khoom thiab tsheb ciav hlau. Lub tshuab muaj peev xwm ntawm 10 cubic meters. m, tuaj yeem nqa cov khoom hnyav txog li 110 tons. Chav tsev yog txhim khu kev qha, ruaj khov thiab muaj kev ua haujlwm zoo.

Nyob hauv kaw

Hom ECG excavators, uas tau tham luv luv hauv peb tsab xov xwm, yog qhov xav tau thoob plaws hauv qhov chaw tom qab-Soviet thiab txawv teb chaws. Qhov no yog vim lawv adaptability rau txawv cheeb tsam climatic, siab productivity thiab zootechnical parameters. Cov tshuab no tshwj xeeb tshaj yog nyob rau hauv kev thov rau ntau yam kev ua haujlwm hauv chaw txua txiag zeb hauv thaj chaw nyuaj thiab thaj chaw uas muaj huab cua hnyav. Lub xub ntiag ntawm ntau qhov kev hloov kho tso cai rau koj xaiv ib lub cuab yeej uas yuav ua kom zoo rau cov yam ntxwv ntawm kev ua haujlwm thiab cov kev xav tau ntawm cov neeg siv khoom.
