無(wú)線遙控多瓣抓斗（液壓系統(tǒng)全球聯(lián)保）
是一種能在空中打開(kāi)的新型單繩抓斗。它既有繩索抓斗結(jié)構(gòu)簡(jiǎn)單、使用可靠的特點(diǎn)，又有動(dòng)力式抓斗生產(chǎn)效率高的特點(diǎn)，它的出現(xiàn)改寫了普通單繩抓斗生產(chǎn)效率低的歷史。
它廣泛應(yīng)用于船舶、港口中、車站、工廠、礦山等物料搬運(yùn)單位。它是煤炭、礦粉、散化肥、黃砂等散貨裝卸的理想工具。
無(wú)線遙控抓斗可以在高溫、嚴(yán)寒、粉塵、雨天等環(huán)境下工作而其性能不受影響，抓斗遙控距離可達(dá)50米以上，抓斗采用了高性能蓄電池，每次充電后，抓斗可連續(xù)作業(yè)100小時(shí)以上,工作原理是：利用電池打開(kāi)電池閥，讓液壓系統(tǒng)開(kāi)始工作。
Wireless remote control grab is a newtype sing letypesingle type can open in the air without any additional energy,It has hoth the advantages ofsimple structureand terminates the low effieciencyof single rope grabin hoisting and transiting.
This grab is widely used inship,port,railway materials(ave.granulation 30mm max 100mm) station,factory,mine and other transport departments,It isan ideal toolin handing bulk car gosuch as coal,orepowder,fertilizer and sand.This grab can be operated well under circumstance of high temperature.Severe cold,dust and rain.There mote distance is more than 50 metres,Thegrab has built-incharger and high efficiency,battery,canoperate. (the hydraulic system is global services)
遙控抓斗工作原理概述
當(dāng)抓斗打開(kāi)時(shí)，滑移座與上承梁接觸而與下承梁是完全分開(kāi)的。此時(shí)電磁換向閥關(guān)閉，由于油缸的活塞桿與滑移座固接，缸筒與下承梁固接，所以此時(shí)油缸活塞桿完全伸出。當(dāng)要抓取貨物時(shí)，起重機(jī)吊索下降，由于油缸活塞可單向?qū)ǎ杂透谆钊麠U能夠收縮，滑移座隨之下降。當(dāng)油缸活塞桿完全收縮后，滑移座也完全落下。然后起重機(jī)吊索上升，滑移座隨之上升，由于油缸的電磁閥處于常關(guān)閉狀態(tài)，此時(shí)，油缸有桿腔被鎖住，在滑輪組的作用下，滑移座上升帶動(dòng)下承梁漸漸向上，同時(shí)帶動(dòng)顎瓣閉合，并抓取物料。
When grab is open, slip block is touching the up beam but it is totally separate with the down beam.Electromagnetic exchange valve is closed at this time. The piston rod of the cylinder and then slip block, and cylinder is firmly jointed together with the down beam, sothe piston rod of the cylinder is fully extended at this time.When the grab is to grab the bulk, crane sling declines and the cylinder is pulled back as the piston rod of the cylinder can be in directed movement，and then the slip block declines.After the piston rod of the cylinder is in complete contraction, slip blocks are totally fallen down.Then the sling of the crane is raised to lead the slip block up. As the electromagnetic valve of cylinder is always closed and the rod end chamber of the cylinder is locked, with the pulley, slip block rises to drive the down beam to up,at the same time; the jaws are closedrod end chamberand grip materials.
