The invention discloses an elevator braking device with a synchronous lifting function. The elevator braking device comprises a clamp body assembly, a lifting mechanism and a synchronizing mechanism;the clamp body assembly comprises two clamp body units, each clamp body unit comprises a wedge block set for clamping an elevator guide rail, and each wedge block set comprises two wedge blocks; the lifting mechanism is used for lifting the wedge blocks to make the clamp body assembly act; the synchronizing mechanism is used for connecting the two clamp body units to make the two clamp body unitsact synchronously; and lifting synchronizing assembly connecting points for fixed connection of the synchronizing mechanism and the lifting mechanism are located between the two wedge blocks of each wedge block set. According to the elevator braking device, by installing synchronizing rods in the middles of clamp bodies of safety clamps, the installation mode can adapt to an elevator arrangement structure in which a car platform wheel is obliquely arranged; and through the integrated design of lifting rods, the lifting rods can execute the function of lifting the wedge blocks in the traditional safety clamps, and meanwhile, the lifting rods can be connected with the synchronizing rods to achieve the functions of triggering the action of the safety clamps and synchronizing the action of thesafety clamps on two sides.

    本发明公开了一种可同步提拉的电梯制动装置,包括:钳体组件,包括两个钳体单元,每个钳体单元包括用于夹持电梯导轨的楔块组;所述楔块组的楔块数量为两个;提拉机构,用于提拉所述楔块使所述钳体组件动作;同步机构,用于连接所述两个钳体单元以使两个钳体单元同步动作;所述同步机构与所述提拉机构固定连接的提拉同步组件连接点位于所述楔块组的两个楔块之间。本发明将同步杆安装在安全钳钳体中间,能够应对轿底轮斜置的电梯布置结构。提拉杆整合设计,使其不仅能够执行传统安全钳中提拉楔块的作用,同时可以连接同步杆,达到触发安全钳动作和同步两侧安全钳动作的作用。
