Electromagnet of built-in inclined plane force-amplifier

Abstract

The invention discloses an electromagnet of a built-in inclined plane force-amplifier. The electromagnet of the built-in inclined plane force-amplifier comprises a magnet yoke, an electromagnetic coil arranged inside the magnet yoke, an armature, and a fastening bolt, wherein the fastening bolt penetrates through the magnet yoke, the magnet yoke forms an embedded groove, an inclined plane force-amplifier is arranged inside the embedded groove, the inclined plane force-amplifier comprises a supporting plate which is flexibly sleeved in the fastening bolt, a driven plate which is tightly connected with the fastening bolt, a driving drive inclined sleeve which depends on the magnet yoke to propel, and a sliding body, wherein the driving drive inclined sleeve is fixed on the magnet yoke, the supporting plate is fixed on the armature, the supporting plate is arranged outside corresponding to the driven plate, a gap is reserved between the inner end of the supporting plate and the end portion of the driven plate, the driving drive inclined sleeve is sleeved outside the driven plate, and the inclined plane section of the driving drive inclined sleeve corresponds to a gapped portion of the supporting plate and the driven plate, and therefore the driving drive inclined sleeve, the supporting plate and the driven plate form a region. The sliding body is loaded inside the region, the sliding body contacts the driving drive inclined sleeve, the supporting plate and the driven plate, and at least two planes of three planes which contact the sliding body are inclined planes.

Description

technical field [0001] The invention relates to an electromagnet with a built-in slope booster mechanism, which can be applied to a block type electromagnetic brake for elevators. Background technique [0002] The existing block-type electromagnetic brake for elevators requires the maximum safe braking positive pressure, so that the magnetic gap space is as small as 0.2mm to 0.3mm, the amount of copper is greatly increased, the weight is heavy, and electric energy is wasted after the pull-in, causing serious heat generation. , It is very difficult to monitor the state of the electromagnet. Once the brake shoes are worn out, the brake safety factor is significantly reduced, requiring frequent adjustments to avoid the elevator car from falling. However, the adjustment process is very troublesome, and the technical requirements for the operators are high, and the accuracy requirements cannot be guaranteed; at the same time, the release time is difficult to meet the actual need...
