Definitions
- the invention relates to a hydraulic cable drive for lifts, with a traction sheave, at least one Braking device and at least one hydraulic motor.
- Such a cable drive is for example in DE-U 69 27 188.
- a traction sheave winch in this document described for passenger and freight lifts, to drive a slow-running hydraulic motor used, the outer housing fixed with a traction sheave connected is.
- the traction sheave is with a Brake device equipped.
- the axis of the hydraulic motor is clamped on both sides of the traction sheave in two bearing blocks.
- the traction sheave rotates with the housing of the Hydraulic motor.
- This drive is big and heavy, the hydraulic motor cannot be reached during maintenance and repair and thus for a machine room-less elevator unusable.
- the object of the present invention is therefore a hydraulic rope drive for elevators available too which stands out for its compact design Installation in the elevator shaft is suitable and the above Does not have disadvantages.
- This task is done with a hydraulic cable drive of the type described at the outset in that the Output shaft of the hydraulic motor directly with the hub of the Traction sheave coupled and the braking device in the Traction sheave or integrated in the hydraulic motor, wherein the hub of the traction sheave on the outside in one inside protruding from the traction sheave, the motor housing load-bearing mounting block is stored.
- the compared to conventional electric motors up to the power density of a hydraulic motor is 20 times higher enables the direct coupling of the drive shaft with the Hub of the traction sheave and thus the waiver of one Gearbox, resulting in a very compact drive structure leads.
- the braking device integrated in the traction sheave In addition to the compact design, it provides an additional one Security because even if the output shaft breaks the elevator is held securely by the brake will and cannot crash. It is also possible easy to maintain and replace the engine if necessary without having to dismantle the entire elevator drive.
- the brake integrated in the motor enables a particularly inexpensive implementation of the drive. When using an appropriately deep-drawn hub the drive motor protrudes only slightly from the traction sheave out.
- the fastener carries next to the motor housing and the traction sheave and possibly the brake. With the fastener is a safe installation of the drive in the Elevator shaft possible.
- the braking device one between the hub and the pulley rim arranged drum brake.
- Such an integrated Drum brake is characterized by a special low space requirements, since it particularly reduces the overall depth of the drive is not enlarged.
- the braking device one on the outside the traction sheave arranged brake disc.
- a those additionally or alternatively attached to the drum brake outer brake disc can vary depending on the application make sense. In addition to an increase in braking power with good meterability, it can in particular system performance for heavily frequented lifts improve the drive.
- a hydraulic Control valve is arranged directly on the actuator.
- the direct arrangement of the control valve on the actuator ensures good stability in the control loop. Line routes too long between the hydraulic motor and the corresponding control valves can cause mechanical vibrations in this hydraulic circuit lead what it is to avoid if possible applies. Preferred due to the direct arrangement on the drive through the most rigid pipe connections between the engine and valve, such vibrations can be effective prevent and good controllability of the drive in all Ensure operating areas.
- An embodiment of the conveyor drive provides that to control the hydraulic control valve, if necessary in this integrated electronic control device, in particular a microcontroller is provided.
- a microcontroller in connection with an electrohydraulic Control valve enables flexible control and regulation of the elevator. So the drive system for configure a wide class of application areas and achieve a correspondingly flexible system structure.
- the control problems that arise i.e. the loading and Direction of travel, dependent mode of operation of the Motors as brakes or drives in the forward or reverse direction mastered safely by a microcontroller.
- the invention also relates to an elevator an elevator shaft and an elevator car as well as one cable drive described above, which is characterized by that the drive is provided in the elevator shaft.
- the arrangement of the drive in the elevator shaft offers one A number of advantages, in particular that no machine room more must be provided as to the cost of such Elevator system significantly reduced. Such orders are only due to the particularly compact design of the drive according to the invention. Until the drive and the valve are no other components in addition to the elevator and counterweight in the elevator shaft, since the hydraulic supply to any, even further distant place can be housed.
- a cable drive according to the invention is, as shown in Fig. 1, in the shaft head of an elevator shaft.
- an elevator car 2 and a counterweight 3 are arranged, which has about the same mass as the elevator car plus their half maximum payload. Both the elevator car as well as the counterweight can be moved vertically guided in rails 4.
- a support cable 5 is from its one-sided attachment in Shaft head over rollers at the elevator car over a Traction sheave 6 of drive 1 to one on counterweight 3 attached pulley and from here to his second Fastened in the shaft head.
- the suspension cable 5 can also be a flat belt with steel wire inlays be used.
- the traction sheave 6 of the drive 1 is driven by a hydraulic motor 7 driven and decelerated. Via supply lines 8 is hydraulic fluid from a Pressure medium supply 9 passed to the engine 7.
- the construction of the cable drive according to the invention is in Fig. 2 shown in more detail.
- the traction sheave 6 is preferably with spherical roller ball bearings 10 in a mounting block 11 rotatably mounted.
- a motor shaft 12 of the hydraulic motor 7 is positive (key 13a) connected to the hub 13 of the traction sheave, so that a Power transmission in both directions of rotation between the motor 7 and the traction sheave 6 is possible.
- the mounting block 11 is also a drum brake device arranged.
- a revolving exterior Edge of the traction sheave 6 is designed as a brake disc 16.
- the fastening block 11 has fastening screws in the lower section 17 on which he is on a carrier 18 can be attached in the shaft head, as shown in Fig. 3 is shown in more detail.
- the brake disc 16 attached to the outside of the traction sheave is hydraulic by a braking device 19 by two vented brake shoes 20 held.
- the invention is not based on the embodiment limited, but can be modified in many ways without leaving the basic idea. So are particularly dependent on the application, different Hydraulic motors can be used. The dimensions too and configurations of the traction sheave, the braking devices designs integrated in the engine, etc. can can be varied depending on the application.
