Definitions
- the invention relates to a braking device for a Drive machine of an elevator consisting of one Bearing block rotatably mounted brake levers on a Brake drum acting brake shoes, the brake lever at the free ends using a fixed Guide element are guided and from in the direction of Actuating element acting pressure springs be, to release the brake shoes the compression springs counteracting magnets are provided.
- a disadvantage of the known device is that in the case of braking devices for larger drive machines Transfer of large braking forces to the brake drum without additional measures for reasons of Material deformation is not possible.
- the Monitoring the position of the brake shoes is complex.
- the invention seeks to remedy this.
- the invention as characterized in claim 1, solves the problem to avoid the disadvantages of the known device and to create a braking device with the larger one Drive units can be braked reliably.
- the advantages achieved by the invention are in essential to see in that with a simple Construction of the braking device and the Bracket bearing bracket a stiff Braking device is feasible, with the larger one in particular Braking forces can be easily transferred to the brake drum are.
- the dimensional stability and function of the Brake release system can be improved at the same time reduced material and weight.
- the inventive device can the accuracy of Use point for brake ventilation can be improved what in turn has a positive effect on the driving comfort of the elevator car affects.
- the arrangement of the sensors for monitoring the Brake lever and the wiring of the brake magnet is without great effort possible.
- Fig. 1 shows a gearless drive machine 1 with a Motor 2 consisting of stator and rotor, one Traction sheave 3 drives. About the traction sheave 3 and one Deflection pulley 4 are ropes, not shown, which an elevator car, not shown, and a not Wear and drive the counterweight shown.
- the Traction sheave 3 is carried by a motor shaft 2.1 one end of a bearing plate, not shown, and is mounted at the other end on a bearing block 5.
- Engine 2, End shield, bearing block 5 and deflection roller 4 are from one Machine console 6 worn.
- the drive machine also includes a braking device 7 a first brake lever 8 and a second brake lever 9, on each of which on a brake drum, not shown acting brake shoe is arranged.
- the brake drum is for example, formed as a collar of the traction sheave 3.
- the brake levers 8, 9 are articulated on the bearing block 5 below stored and guided on a rod 10 above.
- Guide element serving rod 10 is centered on a the bracket 5 connected holder 11 is arranged.
- Compression spring 12, 13 provided.
- a magnet is provided which is contrary to Compression spring works.
- the magnets are on a frame 14 arranged, which is connected to the bearing block 5.
- a touch guard 15 covers the ropes between the Traction sheave 3 and the deflection roller 4.
- Another, Contact protection covers on the Back of the engine 1 the ropes between the Traction sheave 3 and the machine console 6.
- a fan 16 is provided for the drive unit 1.
- On Junction box 17 serves as an interface for lines of energy supply and as an interface for Control lines.
- a manual drive 18 is for emergency operation of the elevator provided that the tool shaft 2.1 without tools can be coupled.
- An end cover 19 of the bearing block 5 has an opening 20 through which the manual drive 18 can be coupled to the motor shaft 2.1.
- the hand drive 18 can be driven by means of a handwheel 18.1.
- the elevator car In case of emergancy the elevator car is manually in depending on the load Upward or downward to the next Stop moves and the passengers are evacuated.
- a brake release lever 21 Motor shaft 2.1 moved manually, the elevator car is lowered or raised.
- the brake release lever 21 exists from a yoke 22 with a first claw 23 and from one Lever bar 24 with a second claw 25, the yoke 22 is articulated at a pivot point 26 of the rod 24.
- the brake shoes or the brake lever 8.9 Brake release lever 21 placed on the rod 10 and the Lever rod 24 moves forward, countering a force the spring force of the compression springs 12, 13 by means of the claws 23.25 acts on the brake lever 8.9 and the brake shoes ventilates.
- Fig. 2 shows the structure of the braking device 7.
- Die Brake levers 8.9 can be turned at one end on lever axles 49.50 arranged, 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 rotatable on one Jaw axis 53,54 arranged.
- Each brake lever is 8.9 at the other end by means of a rod 10 which is connected to the Holder 11 of the bearing block 5 is connected.
- the towards The compression springs 12, 13 acting on the rod axis press the rod-side lever ends towards the holder 11, the Brake shoes 51, 52 brake the brake drum and / or hold tight.
- the brake lever 8.9 a widening 55.56, which serves as a support for a Armature disk 57.58 is used.
- the armature disk 57.58 is through the magnetic force of an electromagnet 59.60 against 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 one Magnetic carrier 61,62 arranged.
- the magnetic carrier 61.62 together with stabilizers 63, 64 form the frame 14, the magnetic carrier 61, 62 firmly on its underside the bearing block 5 are connected.
- the rigid frame 14 takes the forces generated when the brake is released.
- each magnetic carrier 61, 62 is a Microswitch 65 arranged by means of mounting brackets 66.
- a plunger 67 of the microswitch 65 is turned on the armature disk 57 arranged cam 68 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 of the magnet carrier 61, 62 is by means of a a mounting plate 69 on the magnetic carrier 61, 62 held cover 70 completed, being at the as Touch protection cover 70 recesses 71 for the plunger 67 of the microswitch 65 and for electrical Lines are provided.
