Definitions
- the invention relates to self-raising platforms, lifts, mounts materials driven by a pinion rack drive guided along one or more masts that we will call to simplify machines with vertical displacement.
- the invention aims to propose improvements in the drive system, mainly to reduce the extreme forces in case of damage and also to significantly improve safety.
- a centrifugal / freewheel brake assembly located in a coupling bell 8 is inserted between each motor and each gearbox.
- the order in the kinematic chain - (see FIG. 1) - starting from pinion of the rack 1 is as follows: Slow shaft of the gearbox 3, one or more stages of reduction 4, centrifugal brake 5, driven part of the freewheel 6, driving part of the freewheel 7, rotor motor 9, break brake current blocking the rotor on the stator 10 ( Figure 1).
- a machine weighing 1000 kg of own weight and capable of carrying 1000 kg of payload will exert on a downhill obstacle a force of between 1000 and 2000 kg depending on whether it is not is loaded, if the geared motor or gearmotors are equipped with a free wheel, and a force between 5000 and 6000 kg if they are not equipped.
- a rigid coupling is comparable to a machine that would be driven by a motor group and connected to it by a rigid bar.
- a coupling with freewheel is comparable to a machine that would be driven by a motor group and suspended from it by a flexible cable. Downhill if the machine encounters an obstacle, the cable relaxes.
- the freewheel is a cable of infinite length, but never tangled or slack.
- the other motor will turn in the vacuum, creating no downward thrust.
- the total force that must be able to take back the structure will be half of the moving masses is 1000 kg.
- the locked geared motor must be able to recover an extreme total force of 4000 kg while in the solution of the invention, an extreme capacity of 2000 kg is sufficient.
- This invention also applies to a higher number of machines working together on several masts. It is particularly interesting in the case of platforms of substantially square or circular shape.
- FIG. 2bis represents the block diagram for six motors
- the intensity absorbed When mounted, if a geared motor associated with a motor rotates in a vacuum (gear wheel broken, key inoperative, freewheel damaged), the intensity absorbed will be of the order of 0.3 times its nominal intensity, while the other two will consume between 0.75 and 1.5 times their rated intensity depending on whether the machine is empty or loaded.
- the GFCI will trip at ⁇ t.
- each gear motor is mounted as a pendulum, that is to say that the slow shaft of the gearbox is mounted on one or more bearings or bearings 21 and 22; the bearings 21 and 22 are also attached to the guiding structure of the machine.
- the casing of the gearbox is locked in rotation by at least one axis or a strainer with strain gauge 23. This gauge 23 is used to measure the torque induced on the corresponding geared motor.
- this strain gage system on each geared motor offers the double advantage of being able to know the load on the machine, which is the sum of the load on each geared motor and to determine a setpoint which stops the machine in the case where a excessively large charge difference in a given time remains.
- the comparator housing comprising as many operational amps as there are gauges, will control the power supply cutoff in accordance with the predetermined ⁇ load and ⁇ time settings.
- This third improvement can be mounted alone or in second safety with the differential current circuit breaker
- power supply brakes 10 are supplied independently by a battery-backed system.
- a battery-backed system In the event of a break in the main power supply, it is always possible to descend by gravity by opening the brakes with lack of current. The descent speed is then regulated by the centrifugal brakes present on each geared motor unit.
