[0002] The elevator brake is an important safety device for elevators. Its safety and reliability are one of the important factors to ensure the safe operation of elevators. The bidirectional thrust elevator brake generates bidirectional electromagnetic thrust when powered on, which disengages the brake mechanism from the rotating part of the motor (i.e. releases it). When the power is off, the electromagnetic force disappears, and under the action of the external brake spring pressure, a friction brake (hereinafter referred to as the brake) is formed for power-off braking.
[0003] However, the above technology often has the following defects: the traditional traction machine brake is an integrated setting, which is very inconvenient for replacing the brake and often requires two or three people to assist in the replacement.

[0033] Working principle: the yoke 1 and the armature 2 are both set in two halves. In the initial state, the yoke 1 and the armature 2 are attracted. When the yoke 1 and the armature 2 need to be separated, the operator starts the opening and closing control component to gradually extend the spring 4 set in the spring hole 3. During the extension of the spring 4, the armature 2 is pushed to move, so that the armature 2 and the yoke 1 are separated until the armature 2 lifts the friction disk (not shown in the figure) to increase the braking force; when the attraction operation is required, the operator starts the opening and closing control component, which is set in the spring hole 3 is gradually compressed, and the spring 4 pushes the armature 2 to move during the compression process, so that the armature 2 and the yoke 1 are gradually attracted.

When the yoke 1 is attracted or separated from the armature 2, the second guide step column 15 is displaced inside the second adapter groove 13, the second guide sleeve 14 and the second step groove 12, playing a guiding and limiting role. In the initial state, the yoke 1 and the armature 2 are attracted and contacted. In the power-off state, the operator rotates the brake release wrench 104 and the fastening bolt 105 counterclockwise to displace the brake release wrench 104 and the fastening bolt 105 away from the yoke 1. At this time, the spring 4 stretches and pushes the armature 2 to displace, so that the armature 2 is separated from the yoke 1. Initially, In this state, the yoke 1 and the armature 2 are attracted and contacted, and when power is turned on, the push rod 111 is connected to the micro switch 112 and transmits a signal. When the yoke 1 and the armature 2 need to be separated, the operator rotates the push rod 111 counterclockwise to displace the push rod 111 and gradually separate it from the micro switch 112 until the push rod 111 is completely separated from the micro switch 112. At this time, the spring 4 stretches and pushes the armature 2 to displace, so that the armature 2 is separated from the yoke 1. By setting the steel ball 106 to engage with the ball groove 11, it is convenient to play a limiting role.
