machine, this brake equipment is by left, right brake facing is braked and is braked on the disc brake rotor, brake wheel with mounting magnetic steel does not directly contact, can't because of action frequently the temperature of brake wheel is risen very high, and magnet steel is lost magnetism, in this structure, when elevator runs, magnet coil is energized, make left control for brake plate and right control for brake plate produce enough electromagnetic forcees attracted each other with overcome come from retarding spring both sides to the left and right by a left side, the elastic acting force that right control for brake plate struts and the nearer distance that attracts each other, and due to the leverage of jointed shaft, make to be positioned at the state that the left adapter plate of jointed shaft bottom and right adapter plate are then in outer, thus make a left side, right brake facing does not clamp brake disc, thus do not brake, when elevator does not work, magnet coil no power, then left, the electromagnetic force do not attracted each other between right control for brake plate, then the brake action of retarding spring starts to play, the power of its enough outer bullet had is by a left side, right control for brake plate struts, now, a left side for jointed shaft bottom, right adapter plate tightens up rapidly, by a left side, brake disc has firmly been clamped braking by right brake facing, manoevreability and the distribution of force of total are more reasonable, retarding spring and brake disc are separately utilized the distance between jointed shaft in the both sides up and down of jointed shaft by the application force of the retarding spring compressed, form a lever force, its application force can be played in greater role ground, compared to existing brake equipment, when needing to reach identical braking force, only need less spring, thus the required electromagnetic force overcoming retarding spring that produces of magnet coil also can diminish, the cost of brake equipment also can have dropped, meanwhile, because the electromagnetic force needed is less, thus the noise produced when making brake equipment work also reduced, in addition, before, rear fixed plate and a left side, right locating plate makes whole brake equipment form a firm stable, the peripheral structure that intensity is high, ensure braking and non-brake operation smooth, carry out with security and stability, be convenient to improve braking effect, in addition, being arranged so that of upper auxiliary braking recoil spring, the buffer action of braking a short period is made at first at brake action, reduce interstructural damage, simultaneously when non-brake state, attracting electromagnetic force can be assisted to control retarding spring, and lower recoil spring, multiple and the quantity be positioned at below jointed shaft is preferably set more than the quantity be positioned at above jointed shaft, then upon completion of the braking and keep braking state time, the unexpected factors such as the disturbance of equipment may be produced, there is the effect of good buffer protection, the braking effect of simultaneously assisting retarding spring to provide certain in braking procedure, and the design of upper auxiliary braking recoil spring and the lower position of recoil spring and other structures of connection makes the globality of whole brake equipment better, be convenient to effectively carrying out of the safety and stability braking operation that quality is high again, the elastic force that retarding spring can provide is greater than elastic force that lower recoil spring and upper auxiliary braking recoil spring can provide widely, the state being so just convenient to brake with non-brake is smooth, rationally, effectively carry out.
as to preferably of the present utility model, left locating plate or right locating plate are fixed on angular adjustment apparatus.The connectivity of optimizing structure, be also beneficial to the angle of the left and right brake facing of adjustment and brake disc, ensure parallel shape, angular adjustment apparatus can adopt existing worm gear, worm structure as far as possible simultaneously.
