The invention discloses a safety support for a lifting platform, which comprises a telescopic sheath and a telescopic rod. The telescopic sheath comprises a sheath, an electromagnet, a sliding iron core and a reset spring. The cross section of the sheath is concave, and the sheath is surrounded by the outside of the telescopic rod, and the upper part of the sheath is connected with the lifting platform; the electromagnet is located at the lower part of the sheath; the sliding iron core is rectangular; The sliding core is V-shaped near the end of the telescopic rod, and the sliding core is located on the left side of the electromagnet; one end of the reset spring is connected with the electromagnet and the other end is connected with the sliding core; the cross section of the telescopic rod is \convex\, the lower end of the telescopic rod is connected with the base of the hydraulic lifting platform, and the telescopic rod is in coordination with the telescopic sheath, and the right side of the telescopic rod is provided with brake teeth. The sliding core can be inserted into the brake teeth to prevent the expansion sheath from sliding out of control. The invention has the advantages of self-locking after the platform stops, avoiding accidents caused by the falling of the loads on the platform caused by the failure of the elevator, making the hydraulic elevator safer and more reliable, reasonable structure design, simple principle and convenient popularization and use.

一種升降平臺(tái)的安全支架
本專利技術(shù)涉及升降裝置領(lǐng)域,具體的說(shuō)是一種升降平臺(tái)的安全支架。
技術(shù)介紹
升降平臺(tái)是一種多功能起重裝卸機(jī)械設(shè)備,起升高度從1米至30米不等;液壓升降平臺(tái)適用于汽車、集裝箱、模具制造,木材加工,化工灌裝等各類工業(yè)企業(yè)及生產(chǎn)流水線,可配裝各類臺(tái)面形式(如滾珠、滾筒、轉(zhuǎn)盤、轉(zhuǎn)向、傾翻、伸縮),配合各種控制方式(分動(dòng)、聯(lián)動(dòng)、防爆),具有升降平穩(wěn)準(zhǔn)確、頻繁啟動(dòng)、載重量大等特點(diǎn),有效解決工業(yè)企業(yè)中各類升降作業(yè)難點(diǎn),使生產(chǎn)作業(yè)輕松自如。但是,液壓升降平臺(tái)將物體或人抬升到較高位置的同時(shí),也使得被抬升的物體存在墜落的風(fēng)險(xiǎn);如果升降平臺(tái)上的物體墜落,不僅對(duì)物體造成損壞,還有可能砸到地面上的人或其它物體,如果升降平臺(tái)上盛裝的是工作人員,則會(huì)直接對(duì)工作人員造成傷害。
技術(shù)實(shí)現(xiàn)思路
本專利技術(shù)提供一種升降平臺(tái)的安全支架,能在平臺(tái)停止后進(jìn)行自鎖,避免因升降機(jī)故障而導(dǎo)致平臺(tái)上的盛放物墜落引起事故,使得液壓升降平臺(tái)更加安全可靠。本專利技術(shù)解決其技術(shù)問(wèn)題所采用的技術(shù)方案是:一種升降平臺(tái)的安全支架,包括伸縮鞘和伸縮桿,所述的伸縮鞘包括鞘體、電磁鐵、滑動(dòng)鐵芯和復(fù)位彈簧,所述鞘體的橫截面呈“凹”形,鞘體包圍在伸縮桿外部,且鞘體上部與升降平臺(tái)相連;所述的電磁鐵位于鞘體下部;所述的滑動(dòng)鐵芯呈長(zhǎng)方體,滑動(dòng)鐵芯與伸縮桿的接近端呈V形,且滑動(dòng)鐵芯位于電磁鐵左側(cè);所述的復(fù)位彈簧一端與電磁鐵相連,其另一端與滑動(dòng)鐵芯相連;所述伸縮桿的橫截面呈“凸”形,伸縮桿下端與液壓升降平臺(tái)的底座連接,且伸縮桿與伸縮鞘形成配合,伸縮桿的右側(cè)面設(shè)置有制動(dòng)齒,滑動(dòng)鐵芯能插到制動(dòng)齒上以防止伸縮鞘因失控而下滑。所述 ...
