The invention discloses a longitudinally arranged sheet type elevator car out-of-control deceleration device. A plurality of resistance sheets are mounted from top to bottom on the left and right sidewalls in an elevator shaft, one ends, facing the elevator shaft wall, of the resistance sheets are connected to a metal expansion box, and the expansion box is internally provided with an explosive and an electronic fuze. When an elevator operates normally, the expansion box is in a compressed state, and a controller calculates a real-time speed of the elevator car according to an electronic signal transmitted by an infrared correlation velometer. When the descending speed of the elevator car exceeds a rated speed by 20%, the controller sends out a signal to the electronic fuze through a signal wire, the electronic fuze detonates the explosive in the expansion box below the elevator car, and the resistance sheets connected to the expansion box pushed by an expansion box wall stretch froma positioning module. The descending elevator car strikes the stretched resistance sheets, so that the resistance sheets are broken or are bended to deform. The kinetic energy of the elevator car is absorbed by the longitudinally arranged resistance sheets, and the elevator car is stopped in the elevator shaft finally.

    本发明公开了一种纵列片式电梯厢失控减速装置,在电梯井内的左右两面侧壁上从上至下安装多个阻力片,阻力片朝向电梯井壁的一端与金属膨胀盒连接,膨胀盒内装设有炸药和电子引信。在电梯正常运行时,膨胀盒为压缩状态,控制器从红外对射测速器传输来的电信号计算出电梯厢的实时速度。当电梯厢下降速度超过额定速度20%时,控制器通过信号线向电子引信发出信号,由电子引信引爆电梯厢下方的膨胀盒内的炸药,与膨胀盒连接的多个阻力片在膨胀盒壁推动下从定位模块伸出。下降中的电梯厢撞击伸出的阻力片,使阻力片折断或弯曲变形,电梯厢动能被多个纵向排列的阻力片吸收,最终停止在电梯井内。
