Problems solved by technology
[0003] With the continuous improvement of elevator safety requirements, when many electromagnetic brakes change from the braking state to the suction state, a larger electromagnetic brake is required due to the greater positive pressure. The attractive force pulls the armature back, which is accompanied by a large pull-back vibration and noise. Long-term vibration will have a negative impact on all parts of the brake.

Embodiment Construction
[0013] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0014] Such as figure 1 In the shown brake damping device, the brake 1 is arranged on both sides of the friction disc of the elevator traction machine.
[0015] The brake 1 generally mainly includes a yoke 2 , an armature 3 , a tongue plate 4 arranged on the armature 3 and a friction plate 5 arranged on the tongue plate 4 , and the yoke 2 and the armature 3 are movably connected as a whole by bolts 6 . The yoke 2 and the armature 3 are arranged in parallel with a gap, and the yoke 2 is provided with an annular groove 7 , and a coil 8 is sleeved in the annular groove 7 .
[0016] At least one shock absorber 9 is arranged inside the yoke 2. In this embodiment, there are four shock absorbers 9. The shock absorber 9 extends out of the yoke 2 and contacts the armature 3. At the same time, each shock absorber 9 are connected with an adjustment device, th...

The invention relates to a brake damping regulating device. A brake comprises a magnet yoke, an armature, a tongue plate and a friction lining. The tongue plate is arranged on the armature, the friction lining is arranged on the tongue plate, the magnet yoke and the armature are arranged in a parallel manner and an interval is retained between the magnet yoke and the armature, the magnet yoke is provided with a ring groove, and a coil is sleeved in the ring groove; at least one shock pad is arranged in the magnet yoke, and the shock pad protrudes from the magnet yoke and is contacted with the armature; and each shock pad is connected with the regulating device, and the regulating device comprises regulating nuts, the regulating nut threads are in threaded connection inside the magnet yoke, and the ends of the regulating nuts is butted against the shock pad. Because the shock pad is additionally provided with the regulating device, when a use part of the shock pad is worn, a non-wearing part of the shock pad is supplemented to the working position through the regulating device, so that the shock pad is continued to be used effectively. The regulating device provided by the invention is simple in structure and convenient in operation, and can effectively enhance the use effect of the shock pad.
Description
technical field [0001] The invention relates to an elevator traction machine brake, in particular to a brake damping adjustment device. Background technique [0002] The brake is an important safety device of the elevator, and its safety and reliability are one of the important factors to ensure the safe operation of the elevator. Electromagnetic brakes usually use a built-in coil winding, which generates or loses electromagnetic force to generate action through the energization or de-energization of the coil winding. [0003] With the continuous improvement of the safety requirements of elevators, when many electromagnetic brakes change from the braking state to the suction state, due to the large positive pressure, a greater electromagnetic attraction force is required to pull the armature back, which is accompanied by a larger force. Pull back the vibration and noise, long-term vibration will have a bad effect on all parts of the brake. Contents of the invention [00...
