Definitions
- the invention relates to a floor cleaning machine comprising a chassis with several wheels, a lifting device and a cleaning device which can be raised and lowered in the chassis by means of the lifting device in the vertical direction.
- Floor cleaning machines with cleaning brushes rotating about a vertical axis are for example from FR2762503, EP2012642, US4182001, US4692959,
- a floor cleaning machine with a brush field that can be raised and lowered is known.
- the floor cleaning machine further comprises a steam field leading to the brush field in the direction of travel.
- the bottom-side contact pressure of the brushes of the brush field can be adjusted via the lifting device.
- the disadvantage of this floor cleaning machine is that the floor cleaning machine is very large overall in structure and thus has considerable lost cleaning surfaces or. the floor close to obstacles is hardly accessible for cleaning. Furthermore, the brushes can only be adjusted to uneven floors over the entire brush field.
- One object is to specify an improved and compact floor cleaning machine which at least partially avoids the disadvantages of the known floor cleaning machines.
- the floor cleaning machine comprises a chassis with several wheels, a lifting device and a cleaning device which can be raised and lowered in the vertical direction by means of the lifting device.
- the cleaning facility comprises a horizontal turntable which is rotatably mounted about a vertical axis and which is equipped with several brushing devices.
- the multiple brush devices each have a cleaning brush on the bottom side under the turntable, which is rotatably driven about a vertical axis via a drive shaft and is mounted on the turntable in a vertical direction and is spring-loaded.
- the floor cleaning machine accordingly has several cleaning brushes rotating around the axis of rotation of the turntable and around itself, which are pressed onto the floor by means of the lifting device.
- Each cleaning brush is spring-loaded and can therefore be individually adapted to uneven floors, which increases the cleaning performance over the entire brush field.
- differently worn cleaning brushes are applied to the floor with comparable contact pressure.
- direction of rotation can optionally be set to counteract one-sided wear of the cleaning brushes.
- the plurality of brush devices are arranged uniformly around the axis of rotation of the turntable.
- the drive shaft of the cleaning brush can each be designed as a ball spline shaft, the drive shaft being loaded with a spring, preferably a compression spring, opposite the ball spline nut.
- the cleaning brush can be articulated, e.g. B. by means of a universal joint, be connected to the drive shaft.
- the turntable can also be equipped with at least one steam device.
- the turntable is equipped with two or more steam devices, which are each arranged between two adjacent brush devices.
- the at least one steam device can have a preferably horizontal steam spray arm with several steam nozzles on the bottom side under the rotary plate.
- the steam spray arm can be rotatably driven about a vertical axis via a drive shaft.
- the axis of rotation is then ideally in the center of the horizontal steam spray arm.
- the drive shaft is designed as a hollow shaft carrying steam.
- the direction of rotation can also be set optionally for the steam devices.
- a steam outlet opening of the respective steam nozzle can be arranged in such a way that the steam hits the floor in the forward direction of rotation, preferably at an angle of 60 to 80 degrees.
- the multiple steam outlet openings are arranged in such a way that at least one is always directed forwards in each direction of rotation, ie that steam always exits forwards regardless of the direction of rotation.
- the other steam outlet openings are accordingly directed towards the rear. If the direction of rotation is changed, it is exactly the opposite.
- the steam outlet openings of the odd steam nozzles ie the first and third
- the steam outlet openings of the straight steam nozzles ie the second and fourth
- the first and fourth steam outlet openings can be directed in the first direction and the second and third steam outlet openings in the second, opposite direction.
- the turntable can further have a cleaning agent spray arm on the bottom.
- the drive shafts of the plurality of brushing devices and / or of the at least one steaming device can be driven via a chain hoist with a hydraulic motor arranged on the top of the turntable.
- the direction of rotation of the multiple brushing devices and / or the at least one steaming device can be set as desired. I.e. the cleaning brushes and steam nozzles turn clockwise or counterclockwise. This optional setting particularly reduces the wear and tear on the cleaning brushes.
- the steam outlet openings are then advantageously set as described above in such a way that, regardless of the direction of rotation, at least one steam outlet opening is always directed forwards.
- the lifting device can comprise at least three, preferably four, threaded spindles with spindle nuts arranged evenly around the vertical axis of rotation of the turntable, which are rotatably connected to the chassis, the spindle nut in each case being firmly connected to a holder for the cleaning device.
- the drive for the spindle nuts is arranged on the chassis.
- the cleaning device can have a shaft device which comprises a hollow shaft fixedly connected to the turntable, the shaft device being mounted in a rotary bearing arranged in the holder of the lifting device, and the shaft device having fluid lines for steam and / or hydraulic fluid and / or cleaning agent having. In this way, the units and devices arranged on the turntable can be supplied with the corresponding fluids.
- Such a structure allows the construction of a very compact floor cleaning machine without preceding steam and / or cleaning agent fields.
- the shaft device can have an outer corrugated ring arranged around the hollow shaft, the hollow shaft forming the fluid line for steam and the respective fluid line for hydraulic fluid and / or cleaning agent being formed in the outer corrugating ring, with one fluid feed line for the fluids each via a rotary feedthrough is connected to the shaft device, and that in each case an outlet of the fluid lines for steam and / or hydraulic fluid and / or cleaning agent is arranged in the lower area of the shaft device and is fluidically connected to the at least one steam device, the hydraulic motor and the cleaning agent spray arm.
- the outer corrugated ring can be firmly connected to the turntable and the outer corrugated ring can be thermally insulated from the hollow shaft via an air gap. Due to the thermal insulation of the steam-carrying hollow shaft from the outer well ring, the fluids carried in the further fluid supply lines are not heated up by the hot steam.
- the chassis can have at least three, preferably four, wheels evenly arranged around the turntable, the wheels preferably each having their own drive.
- the floor cleaning machine can furthermore have a supply unit for supplying the floor cleaning machine with steam and cleaning agent and / or a power generator for supplying and operating the floor cleaning machine with electrical energy.
- the floor cleaning machine is usually operated electrically.
- it can have an electricity generator which can be flanged to the chassis of the floor cleaning machine.
- the supply unit for the steam and the hydraulic unit for supplying the hydraulic motor of the cleaning device can also be flanged to the chassis of the floor cleaning machine.
- the flanges can take place on one side of the chassis, which then defines the rear, so that the floor cleaning machine with the cleaning device can move forward and sideways as close as possible to any obstacles.
