Definitions
- the invention relates to a Drive machine of a lift according to the preamble of claim 1.
- a generic engine is known for example from FR-A-2 387 898.
- a Braking device has become known with one, with a Traction sheave associated brake drum, against the Brake shoes come to rest, by means of joints Brake levers are rotatably mounted.
- the brake levers are arranged on a pivot axis.
- a drawbar is provided which crosses the brake levers enforce, with each end of the drawbar a compression spring is arranged.
- the compression spring supports itself at one end an end stop of the pull rod and the other end against the Brake lever off.
- the end stop is by means of a Adjustable screw displaceable, causing the brake shoe more or less is pressed against the brake drum.
- One Actuator pin penetrates the free end of each Brake lever. Both actuation bolts are from one of depending on a magnet outgoing the spring force of Compressive springs act on counteracting force, so that the brake shoes are lifted off the brake drum.
- a disadvantage of the known device is that in braking devices for larger drive the Transmission of large braking forces on the brake drum without additional measures for the sake of Material deformation is not possible. In addition, the Monitoring the position of the brake shoes consuming.
- the invention as characterized in claim 1 solves the task to avoid the disadvantages of the known device and to provide a braking device with the larger Drive units can be reliably braked.
- the advantages achieved by the invention are in essential to see that with a simple Construction of the braking device and the Brake bearing bearing block a stiff Braking device is feasible, with the particular larger Braking forces easily transferable to the brake drum are.
- the dimensional stability and function of the Brake system be improved at the same time reduced material costs and weight.
- the inventive device can the accuracy of Use point for the brake release to be improved, which turn positive for the ride comfort of the elevator car effect.
- the arrangement of the sensors for monitoring the Brake lever and the wiring of the brake magnets is without great effort possible.
- Fig. 1 shows a gearless drive machine 1 with a Motor 2 consisting of stator and rotor, the one Traction sheave 3 drives. About the traction sheave 3 and a Guide roller 4 are not shown ropes out, the an elevator car not shown and a not wear and propel counterweight shown.
- the Traction sheave 3 is supported by a motor shaft 2.1, the at one end to a bearing plate and not shown the other end is mounted on a bearing block 5.
- Engine 2, End plate, bearing block 5 and guide roller 4 are of a Machine console 6 worn.
- the prime mover comprises a braking device 7 with a first brake lever 8 and a second brake lever 9, at each one on a brake drum, not shown acting brake shoe is arranged.
- the brake drum is For example, designed as a collar of the traction sheave 3.
- the brake levers 8,9 are hinged at the bottom of the bearing block fifth stored and led to the top of a rod 10.
- Guide element serving rod 10 is centered on a with the bearing block 5 connected holder 11 is arranged.
- a Compression spring 12,13 provided to ventilate the brake shoes.
- each brake lever 8.9 provided a magnet which is opposite to the Compression spring works.
- the magnets are on a frame 14th arranged, which is connected to the bearing block 5.
- a contact protection 15 covers the ropes between the Traction sheave 3 and the guide roller 4 from. Another, not shown touch protection covers on the Rear of the engine 1, the ropes between the Traction sheave 3 and the machine console 6 from.
- a fan 16 is provided for cooling the drive unit 1.
- One Terminal box 17 serves as an interface for cables the power supply and as an interface for Control lines.
- a manual drive 18 provided with the motor shaft 2.1 without tools is detachable.
- a cover plate 19 of the bearing block 5 has an opening 20 through which the hand drive 18th with the motor shaft 2.1 can be coupled.
- the manual drive 18 is drivable by means of a handwheel 18.1.
- the elevator car is manually moved depending on the load Upward or down to the next Stop moved and the passengers evacuated.
- Actuate the handwheel 18.1 and simultaneously ventilate the Brake shoes by means of a Bremslmodalhebels 21 is the Motor shaft 2.1 moves manually, with the elevator car is lowered or lifted.
- the brake release lever 21 is made from a yoke 22 with a first claw 23 and one Lever rod 24 with a second claw 25, wherein the yoke 22 is articulated at a pivot point 26 of the rod 24.
- Fig. 2 shows the structure of the braking device 7.
- the Brake levers 8,9 are rotatable at one end to lever axles 49,50 arranged, wherein the lever axes 49,50 with the bearing block. 5 are connected.
- Each brake lever 8.9 is one on the Brake drum acting brake shoe 51,52 rotatably on a Jaw axis 53,54 arranged.
- Each brake lever is 8.9 the other end by means of a rod 10, which with the Holder 11 of the bearing block 5 is connected.
- the direction the rod axis acting compression springs 12,13 press the bar-side lever ends towards the holder 11, wherein the Brake shoes 51,52 brake the brake drum and / or hold tight.
- the brake lever 8,9 a widening 55.56 on, which as a condition for a Anchor plate 57,58 is used.
- the armature disk 57,58 is through the magnetic force of an electromagnet 59,60 against the Spring force of the compression spring 12,13 tightened, the Brake shoe 51,52 released from the brake drum or the Brake is released.
- the electromagnet 59,60 is on a Magnetic carrier 61,62 arranged.
- the magnetic carrier 61,62 together with stabilizers 63, 64 form the frame 14, wherein the magnetic carrier 61,62 on its underside firmly with the bearing block 5 are connected.
- the rigid frame 14 takes the resulting forces when releasing the brake forces.
- each magnet carrier 61, 62 is a Microswitch 65 arranged by means of mounting brackets 66.
- a plunger 67 of the microswitch 65 is connected by means of a the armature disk 57 arranged cam 68 is actuated.
- the Switching state of the microswitch 65 shows the control of the Lift on whether the brake is activated or released.
- other sensors For example, proximity switches can be used.
- the Inside the magnetic carrier 61.62 is by means of a a mounting plate 69 on the magnet carrier 61,62 locked cover 70 completed, wherein at the as Shockproof cover 70 recesses 71 for the plunger 67 of the microswitch 65 and for electrical Lines are provided.
