遙控抓斗工作原理概述
當(dāng)抓斗打開時(shí),滑移座與上承梁接觸而與下承梁是完全分開的。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)?,所以油缸活塞桿能夠收縮,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.
抓斗開啟Grab Opening
當(dāng)需要打開抓斗時(shí),只需按動(dòng)遙控發(fā)射器的開關(guān),液壓系統(tǒng)中電磁換向閥得電,使其換向,油缸有桿腔卸荷。油缸活塞桿分別在滑移座和下承梁的作用下被拉出,滑移座和下承梁分開,抓斗即可逐漸打開。
When open grab,press the switch of the remote control transmitter. Electromagnetic directional valve of the hydraulic system is fully energized to commutate. Therod end chamberof the cylinder offloads.Piston rod of the cylinder is pulled out by the slip block and down beam, and slip block is separated with down beam, so the grab is gradually opened.
紫石*先進(jìn)的遙控抓斗又可變成單繩手拉抓斗
一、技術(shù)原理
由于科學(xué)技術(shù)的高速發(fā)展,單繩抓斗的開閉裝置出現(xiàn)多個(gè)品種,如:只有一種裝置的遙控抓斗、電動(dòng)液壓抓斗、電動(dòng)馬達(dá)抓斗、手拉單繩抓斗、碰地打開單繩抓斗(落地打開單繩抓斗)等,但是每個(gè)抓斗只采取一種開閉裝置。若開閉裝置出現(xiàn)了故障,一時(shí)又缺乏零部件或維修人員,抓斗只能停止作業(yè);再一個(gè)抓斗遠(yuǎn)離維修中心,單繩船用抓斗隨船作業(yè),一旦開閉裝置出現(xiàn)故障,只能棄而不用,影響工作進(jìn)度和降低經(jīng)濟(jì)效益。同時(shí),單繩抓斗遙控開閉裝置雖已試制成功,但是裝置用久了必然會(huì)出故障,特別大噸位的單索抓斗還不能使用。目前,普通單索散貨抓斗開閉時(shí)沖擊較大,并且不能在空中任意位置開啟卸料,影響工作效率。 紫石新型無線遙控散貨抓斗既能使用無線遙控遠(yuǎn)程操作抓斗,又能更換少量零件后快速轉(zhuǎn)換成手拉開閉裝置操作抓斗,也不需要外部電源,僅利用電池充電就可工作,從而增強(qiáng)了抓斗的適應(yīng)性,降低了抓斗的使用成本。同時(shí),又改進(jìn)了開閉裝置,安裝先進(jìn)的無線遙控裝置和柔性開閉液壓緩沖系統(tǒng),使抓斗性能更完善。 本項(xiàng)目的兩用啟閉裝置可使單索抓斗在裝卸作業(yè)中,選擇遙控或手拉的方式,通過抓斗的主油缸、液壓夾桿鍥形重塊或拉桿、手拉夾桿鍥型重塊控制偏心板與斜壓板的離合,達(dá)到控制抓斗開閉的效果。安裝該開閉裝置的散貨抓斗能在空中任意位置卸貨。
二、使用優(yōu)點(diǎn)
新型無線遙控散貨抓斗具有以下優(yōu)點(diǎn) 1. 這種設(shè)置能用遙控或手拉兩用開閉裝置控制單索抓斗,擴(kuò)大了抓斗的使用功能,使抓斗的適應(yīng)性增強(qiáng),工作效率提高。且兩種不同開閉裝置能巧妙、有機(jī)的結(jié)合,裝置結(jié)構(gòu)簡單、可靠,使用方便。當(dāng)一種啟閉裝置故障時(shí),在很短的時(shí)間就能更換開閉裝置,可提高裝卸速度和裝卸效益,減少船舶??繒r(shí)間,縮短船舶運(yùn)行周期。 2. 新型紫石遙控散貨抓斗與普通單索散貨抓斗相比,不僅保持原有的功能,而且增加了無線遙控裝置。無線遙控開閉裝置能在 50m 的范圍內(nèi)控制抓斗自由操作,可提高裝卸速度 25%, 3. 新型紫石遙控散貨抓斗與原無線遙控散貨抓斗相比,在原理上更科學(xué)、結(jié)構(gòu)上更可靠。減少維修成本和時(shí)間,提高裝卸效率。 4. 新型紫石散貨遙控抓斗應(yīng)用先進(jìn)的無線遙控裝置,信號穩(wěn)定,有利安全生產(chǎn),低噪聲,有利于環(huán)境保護(hù)。
三、產(chǎn)品前景
新型紫石遙控散貨抓斗,前景廣闊,將會(huì)代替單繩手拉抓斗或以前只有一種裝置(遙控)的抓斗,是目前世界上*先進(jìn)、*耐用可靠、維修費(fèi)用*低(因液壓系統(tǒng)是進(jìn)口)且工作效率*高的一種新型遙控散貨抓斗。
