The invention relates to the technical field of elevator braking, and discloses a quick-start elevator brake which comprises a bottom plate, a brake wheel, a brake rod, a brake shoe, a transverse frame, an electromagnetic assembly, an electromagnetic armature, an electromagnetic coil and a fixing rod, a sliding groove is formed in the position, located on the transverse frame, of the interior of the brake rod, and a penetrating groove is formed in the middle of the transverse frame; the top end of the fixing rod is fixedly connected with a coil frame, and a movable coil is fixedly arranged in the middle of the coil frame. By designing the coil frame, the movable coil, the ejector rod and the sliding groove, when an elevator needs to be started after braking, the top of the ejector rod enters the sliding groove through deflection of a brake rod during elevator braking, and the winding direction of the movable coil is made to be the same as the winding direction of the electromagnetic coil through driving of the ejector rod; as the two groups of coils are electrified at the same time, the magnetic force of the electromagnetic armature is increased, the magnetic force of the electromagnetic assembly is increased when overcoming the brake spring, and then the elevator is quickly started.
Description
technical field [0001] The invention relates to the technical field of elevator braking, in particular to a quick-start elevator brake. Background technique [0002] The elevator brake is the most important safety device in the elevator field, and it is one of the important factors that can ensure the safe operation of the elevator. When the power is turned off, the electromagnetic thrust disappears, so that the brake lever and the brake shoe are pushed to brake it under the action of the brake spring, thereby causing the elevator to stop. [0003] However, since the elevator is in the braking state except in the normal running state, the potential energy of the braking spring selected in the elevator brake has a particularly large potential energy, which leads to the electromagnetic thrust generated when the elevator needs to move normally. Great elastic potential energy, so that the elevator moves slowly, and when the elevator brakes after running, the potential energy of...
