Kaishan KG520 Surface DTH Drilling Rig — Heavy-Duty Motor-Chain Feed & High Ground Clearance

Kaishan KG520 imhando yedhiziri ine simba guru, ine simba redhiziri, DTH, yakagadzirirwa kuchera dhayamita hombe munzvimbo dzakaoma zvikuru dzekuchera pamusoro pevhu nekuchera matombo. Ichiratidza kufambira mberi kukuru muhunyanzvi, KG520 yakagadzirwa kuti ikwanise kubata maburi makuru nemabhenji akadzika uku ichichengetedza kuvimbika kwakakurumbira uko Kaishan Group, kambani yechitatu pakukura yepasi rose inogadzira compressor, inozivikanwa nayo pasi rose. Shaanxi Kaishan inopa muchina uyu senzira yako yepamutemo yekuwana hunyanzvi hweinjiniya hunotsigirwa neSeattle muKaishan.

Imwe yekuvandudzwa kwakakosha muKG520 ndeyekuchinja kuenda kune inotungamirwa nemota ine roller chain feed system. Kusiyana nema feeds akajairwa e cylinder, magadzirirwo emota-chain anopa simba rekusimudza nekudyisa rakasimba mukati me 4150mm stroke yese. Kugadziriswa uku kunowedzera zvakanyanya kuvimbika kwerig panguva yekuboorwa kwegomba rakadzika (Φ105-152mm) uye kunoderedza zvinodiwa zvekuchengetedza zvinowanzobatanidzwa nema hydraulic cylinders ane cycle high-cycle.

Kugona kuchinjika kwenzvimbo ndeimwe chiratidzo cheKG520. Nekureba kwepasi kwe440mm—kunoda kusvika kaviri kupfuura kwemhando diki—irigi iyi inogona kupfuura nepamatombo makuru nezvipingamupinyi pasina kukuvara kwepasi pechitsiko chayo. Sisitimu yefolting frame track, inofambiswa nemamota ane torque yakakwirira, inobvumira muchina we6500KG kufamba kusvika ku4km/h uye kukunda mazinga e30°, zvichiita kuti ive imwe yeirigi dzinofamba zvakanyanya mukirasi yayo yehuremu.

Simba rekuboora reKG520 rakanangana neinjini yeYuchai YC4DK100-T304 inoshanda zvakanyanya ine simba re73.5KW. Simba iri rinofambisa sisitimu inotenderera ine simba re4000N·m uye inomhanyisa kusvika 100rpm. Pamwe chete ne4150mm feed stroke, iyo inokwana tsvimbo refu dzekuboora (3m), KG520 inoderedza nguva yekuzorora inochinja tsvimbo uye inowedzera nguva ye "bit-on-bottom" yekufambisa mafambiro ezuva nezuva.

Kuti chivakwa chirambe kwenguva refu, takaita kuti imba yacho ikure uye takasimbisa mabum nematanda. Rig iyi inewo nzvimbo yakakura yekuunganidza guruva uye sisitimu yakasimba yekuenzanisa nzira ye ±10° kuti ive nechokwadi chekuti maburi ari pakati pemabhenji asina kuenzana. Nzvimbo yepamusoro yekusvika yakatwasuka inowedzerwa kusvika 3500mm, ichipa envelopu yakakura yekuboorera yekushandiswa kwakakosha senge face drilling ne slope reinforcement.

Shaanxi Kaishan anokurudzira kubatanidza KG520 nemacompressor emhando yepamusoro-soro anotakurika akadai seKSCY310/22 kana LGCY19/21 series. Aya mayuniti anopa 15-22m³/min yemhepo inodiwa kuti ibvise maburi makuru eΦ105-152mm uye ishandise hammer dzeDTH dzine simba re4″ kana 5″. Kubva payakavambwa muna 1956, Kaishan yakagadziridzwa ma pairings aya e rig-compressor kuti ape mutengo wakaderera-pa-mita muindasitiri iyi.
