The invention relates to a safety braking system. The safety brake system includes a safety brake, a linkage, and an actuator for the safety brake. The safety brake is movable between a non-braking position and a braking position. The actuator is configured to be mounted to the conveying member and positioned between the first and second ferromagnetic members. The actuator includes an array of magnetic components including a first magnetic component adjacent to and disposed between two second magnetic components. The first magnetic member includes one of a permanent magnet and an electromagnet, and the second magnetic members each include the other of the permanent magnet and the electromagnet. When the electromagnet of the first or second magnetic component is switched from the first state to the second state, the magnetic field between the array and the first ferromagnetic component is weakened and the magnetic field between the array and the second ferromagnetic component is enhanced so as to move the actuator against the second ferromagnetic component from the first position to the second position.
本发明涉及一种安全制动系统。安全制动系统包括安全制动器、连杆机构和用于安全制动器的致动器。安全制动器可在非制动位置和制动位置之间移动。致动器构造成安装到输送部件并定位在第一和第二铁磁部件之间。致动器包括磁性部件的阵列,该阵列包括邻近两个第二磁性部件且布置在两个第二磁性部件之间的第一磁性部件。第一磁性部件包括永磁体和电磁体中的一个,第二磁性部件各自包括永磁体和电磁体中的另一个。当第一或第二磁性部件的电磁体从第一状态切换到第二状态时,阵列和第一铁磁部件之间的磁场减弱,并且阵列和第二铁磁部件之间的磁场增强,以便使致动器抵靠第二铁磁部件从第一位置移动到第二位置。
