Description
Technical field
The present invention relates to the emergency braking apparatus on a kind of traction sheave that acts on towing machine, belong to lift car and use the protection device for over-speed ascending technical field.
Background technology
GB7588-2003 " elevator manufacturing and installation safety standard " is defined in when arranging elevator the car protection device for over-speed ascending must be installed; This device be used in case of emergency rapidly stop traction sheave or steel rope or to pouring weight with the stop elevator car, perhaps direct stop car.Most in the market bridge railway carriage or compartment protection device for over-speed ascending all acts on the steel rope; Come stop elevator through clamping the elevator traction machine steel rope; This apparatus structure is complicated, heavy, in the stop process, damages steel rope easily, and needs certain installing space.Also have the emergency braking apparatus of some protection device for over-speed ascending as towing machine; Act directly on the traction sheave; The emergency braking apparatus that has comes the stop traction sheave through the internal perisporium face that acts on the traction sheave outer ring, and like Chinese invention patent Granted publication CN1305748C disclosed a kind of " brake shoe for elevator emergency stop ", this emergency braking apparatus requires traction sheave inside to have enough spaces that this device is installed; And the internal perisporium of traction sheave outer ring also will have enough brake surfaces; If traction sheave is when narrow, that specially slot milling brake equipment is installed, and not enough because of the traction sheave width; Brake area also can be not enough, and braking force is not enough to the stop traction sheave for a short time.Also having some brake equipments to act on traction sheave has on the outer ring that steel rope walks around; This brake equipment is at the surface and the steel rope of glancing impact easy abrasion traction sheave, and through after the long-term use, steel rope can be more and more thinner; Need frequent more change steel rope; Increase cost, and be difficult for when more change steel rope of assurance, had potential safety hazard.
In addition; China utility model patent Granted publication CN200985260Y also discloses a kind of " acting on the safety tongs on the traction sheave "; It is to have rolling longitudinally to cooperate on the pedestal or be slidingly fitted in the dragging plate on the pedestal; Have on the dragging plate through bearing pin pivotally attached brake block assembly; One end of dragging plate is connected with a end of drag-line on being installed in pedestal one end through pull bar, and the other end of drag-line is connected with the up velocity limiter of towing machine, between dragging plate and said base one end at least one retracing spring is arranged; The moving shoe plate assembly of limited customization is around the inhibiting device of bearing pin hunting range on the dragging plate, and it also comprises and can clamp the limit switch and the pressing plate that can make it conducting of actuating signal by output safety.The advantage that this patented technology has is: the safety tongs on the traction sheave has overcome above-described defective; Kept prior art to act on the advantage of the brake equipment on the traction sheave, volume is little, simple in structure again, noiselessness and working stability are reliable when not working.But also there is following shortcoming in actual use in said structure: at first, though the brake shoe sheet of this device is to brake at traction sheave not on that a part of outside face of steel rope; But because the traction sheave outside face has grooving, the payload space of braking seldom, through after the braking repeatedly; The outside face of traction sheave is worn easily; External diameter reduces, and braking effect is variation gradually, even can't brake; Secondly, when this device is installed, need the mount pad of frame and so on to come to link, need certain installing space with locating plate, and this complex structure, the Installation and Debugging difficulty, the processing and manufacturing difficulty is big, causes cost than higher.
