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.
【技术实现步骤摘要】
一种升降平台的安全支架
本专利技术涉及升降装置领域,具体的说是一种升降平台的安全支架。
技术介绍
升降平台是一种多功能起重装卸机械设备,起升高度从1米至30米不等;液压升降平台适用于汽车、集装箱、模具制造,木材加工,化工灌装等各类工业企业及生产流水线,可配装各类台面形式(如滚珠、滚筒、转盘、转向、倾翻、伸缩),配合各种控制方式(分动、联动、防爆),具有升降平稳准确、频繁启动、载重量大等特点,有效解决工业企业中各类升降作业难点,使生产作业轻松自如。但是,液压升降平台将物体或人抬升到较高位置的同时,也使得被抬升的物体存在坠落的风险;如果升降平台上的物体坠落,不仅对物体造成损坏,还有可能砸到地面上的人或其它物体,如果升降平台上盛装的是工作人员,则会直接对工作人员造成伤害。
技术实现思路
本专利技术提供一种升降平台的安全支架,能在平台停止后进行自锁,避免因升降机故障而导致平台上的盛放物坠落引起事故,使得液压升降平台更加安全可靠。本专利技术解决其技术问题所采用的技术方案是:一种升降平台的安全支架,包括伸缩鞘和伸缩杆,所述的伸缩鞘包括鞘体、电磁铁、滑动铁芯和复位弹簧,所述鞘体的横截面呈“凹”形,鞘体包围在伸缩杆外部,且鞘体上部与升降平台相连;所述的电磁铁位于鞘体下部;所述的滑动铁芯呈长方体,滑动铁芯与伸缩杆的接近端呈V形,且滑动铁芯位于电磁铁左侧;所述的复位弹簧一端与电磁铁相连,其另一端与滑动铁芯相连;所述伸缩杆的横截面呈“凸”形,伸缩杆下端与液压升降平台的底座连接,且伸缩杆与伸缩鞘形成配合,伸缩杆的右侧面设置有制动齿,滑动铁芯能插到制动齿上以防止伸缩鞘因失控而下滑。所述 ...
