Definitions
- the invention relates to a brake safety device for the load suspension device of a vertical conveyor device with at least one brake wedge (3, 4) arranged in a housing (1), which, when a braking operation is triggered, applies to a brake
- the guide rail (2) of the conveyor vehicle acts and with a stop which limits the stroke of the at least one brake wedge (3, 4) and thus the maximum braking force during the braking process.
- the invention relates to a method for adapting the braking force of this brake safety device to the masses to be braked acting on the load suspension device.
- Brake arresting devices of this type are used, for example, in passenger elevators, freight elevators and for cages in shaft hoisting systems, the braking process usually being triggered when a permissible driving speed is exceeded by a governor rope of a speed limiter acting on the brake wedges.
- a brake safety device in which a slide guide for the wedge housing, which is attached to the elevator car and is made of ink profile, is provided.
- the wedge housing has a tapered recess in the vertical direction, in which two brake wedges are arranged, which surround the guide rail of the elevator with play.
- the brake wedges are mounted on balls in grooves in the recess so that they roll on the wedge surfaces of the wedge housing and brake wedges, so that there is only a slight rolling resistance.
- the two brake wedges can be moved by a double lever that sits on a shaft that is turned by a lever from the governor rope of a speed governor.
- the brake wedges are pressed against the guide rail and the braking process is initiated.
- a support bracket is attached, protruding from the cabin, against which the wedge housing is supported via disc springs. Set screws secured with nuts are arranged on the support bracket, which serve as stops for the brake wedges.
- the brake wedges are drawn into the wedge housing to the extent that they correspond to the thickness of the guide rail.
- the braking forces that occur cause the wedge housing to be lifted against the disc springs until the brakes do not hit the adjusting screws, which prevents a further increase in the braking forces.
- the brake safety device described above has the disadvantage that different deceleration values are generated on the load suspension device with different masses to be braked. With large loads in the load handler, there may be too little deceleration, with small loads an impermissibly high deceleration of the load handler and thus lead to personal injury and property damage.
- the invention is therefore based on the object of proposing a brake safety device according to the preamble which does not have these disadvantages.
- an actuating device which, by moving at least one stop or the housing, determines the deflection of spring elements which occurs in the event of a braking application and thus the spring forces resulting therefrom, these spring elements having the spring force the brake wedges against the guide rails of the load handler.
- the actuating device can thus be used to adjust the at least one stop or the housing as a function of the size of the mass of the load suspension means to be braked and thus influence the braking force between the brake wedges and the guide rail.
- stop or housing can be adjusted continuously while driving. This is important for vertical conveyors that have balancing weights and are equipped with balancing ropes that hang between the underside of the load handler and that of the balancing weight. Since the proportion of the mass of the compensating cables mentioned which additionally influences a braking braking operation changes during the journey, it is advantageous that the position of the stop or the housing, on which the braking force occurring in the case of braking braking depends, can be continuously adapted to this change.
- FIG. 1 shows a longitudinal section through a first brake safety device according to the invention in a simplified, schematic illustration
- FIG. 2 shows a cross section through the brake safety device according to Fig.l.
- 3 shows a longitudinal section through a second brake safety device according to the invention in a simplified, schematic illustration
- FIGS. 1 and 2 1 denotes a housing fastened to a load-carrying means, not shown, of a vertical conveyor device, and 2 denotes a guide rail of the elevator.
- brake wedges 3, 4 are arranged on both sides of the guide rail.
- the brake wedges 3, 4 are supported on the counter shoes 5, 6 and spring elements 7, 8 in the housing 1, the counter shoes 5, 6 and the spring elements 7, 8 being guided in recesses 9, 10 in the housing 1.
- an actuating device 13 that is operatively connected to the stop is provided, by means of which the stop 11 can be positioned depending on the masses currently to be braked.
- These masses consist mainly of the load present in the load handler, the weight of the cabin and the currently effective weight percentage of the lower ropes hanging on the load handler.
- Brake wedges 3, 4 and the guide rail 2 are influenced in such a way that, regardless of the size of the masses to be braked, a delay occurs in the event of a stop braking, in which, on the one hand, the load suspension device is stopped safely and, on the other hand, no personal injury or material damage occurs.
- the adjusting device 13 can have, for example, an adjusting drive which contains a servo motor and a screw spindle driven by the latter, with which the stop 11 is positioned.
- the actuating device 13 also contains a position control device which is dependent generated by several input signals control signals for the servo motor. At least one input signal, which reports the position of the stop, and a signal generated by a load measuring device, which represents the size of the load in the load suspension device, are evaluated.
- a further input signal can be taken into account, which represents the variable, currently effective mass of the compensating ropes as a function of the vertical position of the load suspension device.
- actuating devices can also be used for the stop positioning, such as, for example, hydraulically actuated servo actuating cylinders or motor-driven cam disks.
- Brake wedges and guide rail create a braking force which is dependent on the position of the stop 11 and counteracts the movement of the load-carrying means.
- the stop 11 on the Load suspension means to be fixed and the housing 1 with brake wedges 3.4, mating shoes 5.6 and spring elements 7.8 are moved.
- the triggering and braking effect of the safety gear remain practically unchanged.
- the embodiment according to FIG. 3 has, instead of the stop 11 determining the end position of the brake wedge, two stops 15 guided in the area of the recesses 9, 10 in the wall of the housing 1.
- Two actuating devices 14 position the abovementioned stops 15 before each journey and possibly also during a journey such that, in the event of emergency braking, the spring deflection of the spring elements 7, 8 and thus the spring forces resulting therefrom, with which the spring elements 7, 8, brake chocks 3, 4 press against the guide rails 2, which are adapted to the mass currently to be braked.
- the functional properties of the actuating devices 14 correspond to those of the actuating device 13 described above.
