Problems solved by technology
[0003] After the traditional elevator brake is powered off, the electromagnetic force of the two-way electromagnetic thrust brake disappears when the power is turned off. It will generate heat. During the braking process, if the friction time is too long, the temperature will rise to a higher temperature, causing the friction brake pads to melt or even catch fire due to excessive temperature, which will affect the braking effect of the elevator brake and cause safety hazards.

The invention discloses a high-temperature-resistant elevator brake. The high-temperature-resistant elevator brake comprises a push rod, a machine body and a base, wherein the machine body is fixedlyconnected with the base, a back mounting plate is welded on the machine body, a fan is arranged on one side of the back mounting plate, the two sides of the machine body are correspondingly in hinge connection with a left clamping plate and a right clamping plate, the left clamping plate and the right clamping plate are correspondingly provided with rubber plates, and cooling pipelines are correspondingly arranged in the left clamping plate and the right clamping plate. According to the high-temperature-resistant elevator brake, through the arranged fan and formed heat dissipation holes, the brake is cooled in the working and braking processes, so that the brake is resistant to the high temperature; due to the fact that a cooling liquid conveying device is arranged, a cooling liquid is conveyed into the cooling pipelines and absorbs heat generated by friction of the rubber plates during braking, and the cooling liquid which absorbs the heat is cooled through a cooling liquid storage tank, so that the cooling liquid can circularly absorb the heat multiple times; and the rubber plates are resistant to the high temperature, so that the braking effect of the elevator brake is increased.
Description
technical field [0001] The invention relates to the technical field of brake equipment, in particular to a high temperature resistant elevator brake. Background technique [0002] The elevator brake is a two-way electromagnetic thrust brake that produces a two-way electromagnetic thrust when the brake is energized, so that the brake mechanism is separated from the rotating part of the motor (that is, released), and the electromagnetic force disappears when the power is turned off. Friction brakes. It is mainly matched with the driving motor on the escalator traction machine to form an electromagnetic braking three-phase asynchronous motor for escalators. It is widely used in occasions that can realize smooth parking and fast starting and safe anti-braking when power is off. This brake has the characteristics of It has the advantages of compact structure, convenient installation, low noise, small vibration, large electromagnetic thrust, sensitive action, and reliable braking...
