Definitions
- the present invention concerns a
- grinding machine comprises a rotatable grinding disc, which is driven by a motor and carried by an articulated motor housing supporting the grinding disc on the chassis of the machine .
- the main object of the present invention is primarily to efficiently, ergometrically correctly as well as in a cost-saving way solve said problems .
- the invention also concerns a device for the realisation of a proceeding as mentioned above.
- a compression spring and/or a tension spring is arranged for counterbalancing the motor housing and the grinding disc carried thereby, and that said spring is arranged to act between the motor housing and the chassis of the machine on one side of the same interconnected pivot joint, preferably in pairs.
- a floor cleaning machine is known, which is provided with a scrubbing or polishing wheel (61) however no grinding machine.
- the known floor scrubbing machine has a rotatable scrubbing brush, which is turnably mounted on pivots (7, 8) .
- Springs (17) situated in line with the motor on each side of the centre line of the machine holds a supporting plate (11) in horizontal position in relation to the substratum (22) .
- a grinding disc is held in horizontal position in relation to the substratum by being pressed down from the frame of the machine. This has not been shown to be previously known by prior art in the field.
- Fig. 1 shows a right side view of a floor grinding machine equipped with shown device according to the invention
- Fig. 2 shows in more detail the invention in close-up
- Fig. 3 shows a side view as seen from the left of a floor grinding machine likewise provided with the invention but which cannot be seen from said side, and
- Fig. 4 shows a perspective view of a floor grinding machine obliquely from the front right side.
- the invention may, e.g., be applied to a floor grinding machine 1, where a grinding disc 2 shaped as a drum with, e.g., three pads equipped with abrasive segments of desired type rotates in a common direction and the larger disc-shaped drum 2, on which the pads are journally supported, rotates in the opposite direction, wherein the grinding becomes even and that there will be a small pull laterally when one operates and walks with the machine holding a handle 4 on the intended substratum 3 , e.g., a concrete floor desired to be evenly ground.
- a grinding disc 2 shaped as a drum with, e.g., three pads equipped with abrasive segments of desired type rotates in a common direction and the larger disc-shaped drum 2, on which the pads are journally supported, rotates in the opposite direction, wherein the grinding becomes even and that there will be a small pull laterally when one operates and walks
- Example thereof is shown in Fig. 1 where the handle 4 is held in raised running position I.
- the handle 4 is shown in lowered storage and transport position II.
- an electric motor 5 is shown, which is placed mounted relatively central on the machine 1 essentially straight above the balancing point 7 of the motor housing 9. In that connection, there is not such a large risk of imbalance of the machine 1.
- the present invention intends to solve this serious problem by a machine 1 that can be utilized in a proceeding of the above-mentioned type for
- grinding machine 1 comprises a rotatable grinding disc 2, which is driven by a motor 5 and carried by an articulated motor housing 9 supporting the grinding disc 2 on the chassis 10 of the machine by allowing counterbalancing the motor housing 9 in question so that the same becomes balanced in relation to the chassis 10 of the machine.
- At least one spring 11 is utilized as balancing aid arranged so that the same counteract (s) weight/torque from a motor 5 carried by the motor housing 9.
- a tension spring 11 and/or a compression spring are/is utilized, which are/is arranged to counteract the weight/torque from said motor 5 and other weighty parts of the machine.
- a device suitable to be applied in the realisation of a proceeding for facilitating the handling of a manually drivable grinding machine 1 for floors 3 and other similar surfaces and which grinding machine 1 comprises rotatable grinding disc 2, which is driven by a motor 5 and carried by an articulated motor housing 9 supporting the grinding disc 2 on the chassis 10 of the machine comprises means for counterbalancing the motor housing 9 in relation to the chassis 10 of the machine and which is arranged to extend between the same so that said means compensates possible imbalance between the motor housing 9 and said chassis 10 of the machine.
- Said means is comprised of at least one spring 11, which is arranged between the motor housing 9 and the chassis 10 of the machine so that said spring 11 is connected to counterbalance the parts of the motor 5 and possible other biased parts thereon.
- suitably two springs 11 are arranged in the indicated way, one spring 11 situated on each side of the motor housing 9, as seen laterally and in the intended direction of travel and longitudinal centre plane 13 of the machine.
- a compression spring and/or a tension spring 11 are/ is arranged for counterbalancing the motor housing 9 and the grinding disc 2 carried thereby and said spring (s) 11 is/are arranged to act between the motor housing 9 and the chassis 10 of the machine on one side of the same interconnected pivot joint 12, preferably in pairs with a spring 11 arranged on each side A, B of the longitudinal centre plane 13 of the machine as seen in the longitudinal direction 14 of the machine.
- a fixing clamp 30 of the motor housing 9 may perform the function of anchoring the spring (s) 11 with the lower end 15 thereof and that the spring (s) 11 is/are anchored to a suitable portion of the chassis 10 of the machine by the respective upper portion 16 of the
- Said spring 11 is fixed to the motor housing 9 and the chassis 10 of the machine with the respective ends 15,16 via pivot joints 12, preferably in the form of ball-and-socket joints, and said spring 11 is mounted between the pivot joint 12 for the bearing
