The invention discloses a high-speed elevator braking device which comprises an elevator braking device body, a fixing base mechanism, a clamping arm A and a clamping arm B. The fixing base mechanismis arranged on the elevator braking device body, a pulley is arranged in the fixing base mechanism, and the clamping arm A and the clamping arm B are symmetrically arranged above and below the fixingbase mechanism. One end of the clamping arm A and one end of the clamping arm B are installed in clamping arm moving grooves, close to the two ends, of a fixing block, a hydraulic oil cylinder is arranged between the other end of the clamping arm A and the other end of the clamping arm B, the clamping arm A and the clamping arm B are controlled to get close to each other through the hydraulic oilcylinder, after pressure relief of the hydraulic oil cylinder, the clamping arm A and the clamping arm B are pushed off rapidly through a spring, and the clamping arm A and the clamping arm B are separated from a steel wire rope. The device is reasonable in design, effective braking is achieved in a mutual extrusion braking manner, and the stability of the device is high.
本发明公开了一种高速电梯制动装置,包括电梯制动装置,固定座机构,夹臂A,夹臂B,电梯制动装置上设有固定座机构,固定座机构的内部设有滑轮,固定座机构的上方与下方对称设有夹臂A,夹臂B,夹臂A,夹臂B的一端端头安装在固定块靠近两端的夹臂活动槽内部,夹臂A与夹臂B的另一端之间设有液压油缸,通过液压油缸来控制夹臂A,夹臂B之间相互靠拢,液压油缸解压后,弹簧迅速将夹臂A与夹臂B推开,使夹臂A与夹臂B与钢丝绳之间分离,本装置设计合理,采用相互挤压制动的方式起到有效的制动,装置的稳定性高。
