Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a friction lining of the present invention and the scheme drawing that is connected of brake ratchet.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is further described:
As depicted in figs. 1 and 2; A kind of staircase constant force friction-type additional brake safety device of the present invention; Its structure is; It comprises brake ratchet 1, can also comprise slipper pushing mechanism, electromagnet 5, friction lining 7 around the slipper 2 of fulcrum rotation, and when slipper 2 actions, the retarding spring 8 of pressure is provided can for friction lining 7; The left and right sides of said brake ratchet 1 is provided with said friction lining 7, and said retarding spring 8 connects said friction lining 7; Said slipper 2 is arranged at brake ratchet 1 below, and said electromagnet 5 connects said slipper pushing mechanism, and the slipper pushing mechanism connects said slipper 2, and slipper 2 can mesh with brake ratchet 1 under the promotion of slipper pushing mechanism.As preferred embodiment, said slipper pushing mechanism comprises push rod 3 and push rod spring 4, and said push rod spring 4 one ends are connected in electromagnet 5, and the other end of push rod spring 4 connects an end of push rod 3, and the other end of push rod 3 is articulated in said slipper 2.Electromagnet 5 is under "on" position, and slipper 2 leaves brake ratchet 1; Electromagnet 5 is under off-position, and the take-off lever of electromagnet 5 ejects, and makes push rod spring 4 drive push rod 3 promotion slipper 2 and rotates up, and slipper 2 provides brake application by spring for the braking sour jujube with brake ratchet 1 engagement, slipper 2.Wherein, said electromagnet 5 is electrically connected with staircase system controlled by computer mainboard, and staircase system controlled by computer mainboard is electrically connected with the host code device.
As preferred embodiment; A kind of staircase constant force friction-type additional brake safety device of the present invention also comprises outer dish 10 of the braking that is arranged at brake ratchet 1 left and right sides and braking inner disc 9; Two friction linings 7 are arranged at outer dish 10 of said braking and braking inner disc 9 respectively; Link together through screw rod between outer dish 10 of braking and the braking inner disc 9, the outer dish 10 of braking is used for fixing with braking inner disc 9 installs friction lining 7.As preferred embodiment, said push rod spring 4 is provided with travel switch 6 near an end of electromagnet 5, is used to control the shift motion of push rod spring 4 machine push rods 3.
