Abstract
The utility model relates to an elevator component, in particular to an elevator traction machine brake. The elevator traction machine brake comprises a base which is installed on one side of a traction machine brake disk in a floating mode, wherein an electromagnetic coil is installed on the base, a suction cup which can be sucked by the electromagnetic coil is arranged between the front end surface of the base and the rear side surface of the brake disk, a compression spring is pressed between the suction cup and a sucking surface of the base, a clamping support which is fixedly connected with the base is arranged in front of the suction cup, brake shoes are respectively arranged on corresponding surfaces of the clamping support and the suction cup, and the traction machine brake disk is located between the clamping support and the brake shoes of the suction cup. The elevator traction machine brake has simple structure, small volume and high movement reliability.
Description
Technical field
The utility model relates to a kind of elevator components, specifically is a kind of elevator machine brake.
Background technology
The brake component of traditional elevator traction machine generally adopts drum brake mechanism, and its structure is complicated, it is bigger to take up room, and can only be applicable to the gear type towing machine that some volumes are bigger, and can't be applied in the compact small-sized towing machine of structure.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, volume is little, reliable in action is high elevator machine brake.
Elevator machine brake of the present utility model includes a unsteady base that is installed in towing machine brake disc one side, magnet coil is installed on the base, being provided with one between the trailing flank of base front end face and brake disc can be by the sucker of magnet coil adhesive, be pressed with compression spring between the adhesive face of sucker and base, sucker the place ahead is provided with a supporting seat of captiveing joint with base, be respectively arranged with brake facing on supporting seat and the sucker facing surfaces, the towing machine brake disc is promptly between the brake facing of supporting seat and sucker.
The rear surface of described sucker is provided with the damping block of several elastomeric materials, and the bump that produces with base when reducing the sucker adhesive vibrates and noise.
Described sucker rear surface also is connected with a pull bar, the rear end of this pull bar is passed base and is connected with the plate of manually stopping, the plate of manually stopping can be that rotating shaft is rotated with the pull bar, manually stop plate with base rear end face bonding surfaces on be placed with several sphere pits, each sphere pit and rotating shaft center equidistantly are provided with, while is provided with several blind holes in the relevant position of the aft end face of base, be mounted with ball in the blind hole, the slightly larger in diameter of ball is in the degree of depth of blind hole, some is projected on the aft end face of base to make ball, and when the sphere pit was relative with blind hole, the jut of described ball was arranged in the sphere pit.
The utility model is simple in structure, volume is little, can be applicable to midget plant, reliable in action, and can realize hand brake.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the base 1 of this elevator machine brake is positioned at brake disc A one side of towing machine, base can pass through magnet coil 2 and the adhesive mutually of sucker 3 rear surfaces, compression spring 4 is set between their adhesive face, the rear surface of sucker is provided with the damping block 5 of several elastomeric materials, vibration and noise during with the reduction adhesive, sucker the place ahead is provided with the supporting seat 6 of captiveing joint with base, the brake disc of towing machine is between sucker 3 and supporting seat 6, when magnet coil 2 outages, sucker and supporting seat can carry out friction braking by brake facing 7 clamping brake disc A under the effect of compression spring 4.
Sucker 3 rear surfaces are connected with a pull bar 8, the rear end of pull bar is passed base and is connected with the plate 9 of manually stopping, the plate of manually stopping can be that rotating shaft is rotated with the pull bar, manually stop plate 9 with base rear end face bonding surfaces on be placed with several sphere pits 10, each sphere pit and rotating shaft center equidistantly are provided with, while is provided with several blind holes 11 in the relevant position of the aft end face of base 1, be mounted with ball 12 in the blind hole, the slightly larger in diameter of ball is in the degree of depth of blind hole, and some is projected on the aft end face of base to make ball.When the rotation manual plate 9 of stopping, when making sphere pit 10 and blind hole 11 relative, the jut of described ball is arranged in the sphere pit, and this moment, sucker 3 was braked brake disc A under the effect of compression spring 4; When the rotation manual plate 9 of stopping, when sphere pit 10 and blind hole 11 are staggered, the jut of ball will manually be stopped the plate top from the aft end face of base, and then pulling sucker and brake disc disengagement.
