Definitions
- the present invention concerns a machine for levelling concrete, in other words a machine for smoothing concrete in order to form a floor, slab, path or such.
- the invention concerns a moveable machine which can be universally used.
- the aim of the invention is to provide a machine of the abovesaid type which is still further improved and can be universally used.
- the telescopic guide preferably consists of a rail construction along which a carriage can be moved which carries the element to be moved. This construction is particularly useful when the machine is provided with a polishing part to be moved back and forth.
- only one or several of the tools can be adjusted in the width, i.e. across the driving direction, in other words the device to spread the concrete and/or the device to vibrate the concrete and/or the device to smoothen the concrete and/or the poshing device.
- all these tools can be adjusted in the width.
- the tools can be adjusted in the width, but also the propelling means.
- the adjusting means to adjust the width of one or several of the tools are connected to the propelling means, one and other such that by changing the width of the propelling means, the width of the tools concerned is automatically changed, in other words the working width or the width of the concrete path to be made.
- adjusting means which allow for a continuous adjustement, such that each path width can be realized between a certain minimum value and a certain maximum value.
- the invention concerns a machine 1 for levelling concrete 2.
- the machine 1 hereby mainly consists of a frame 3, propelling means 4 and a number of tools fixed to the frame 3, such as a device 5 to spread the concrete 2, a device 6 to vibrate the concrete 2, a device 7 to smoothen the concrete 2 and a polishing device 8 to obtain a perfectly smooth surface.
- the frame 3 may have different shapes.
- a superstructure 9 can be provided on the frame 3, such as a cabin or the like for the driver of the machine in which are also provided the control devices to control the machine.
- the frame 3 is supported by columns 10.
- the above-mentioned propelling means 4 consist of roller means, preferably caterpillars 11, which are operated by means of drive means, for example hydraulic motors 12. It is clear that also other drive means can be used.
- the above-mentioned propelling means 4 are situated under the columns 10.
- the above-mentioned device 5 to spread the concrete may consist of one or several distributing screws 13.
- the above-mentioned device 6 for vibrating the concrete 2 consists of one or several vibrating shoes 14, which are driven for example by means of an oscillator which is not represented here.
- the above-mentioned device 7 for smoothing the concrete 2 consists of one or several spreaders 15.
- the polishing device 8 mainly consists of a polishing plate 16 which can be moved over the concrete. Said polishing device 8 will be further described in detail by means of figures 4 to 9.
- the machine 1 can be adjusted in the width, in other words it has means with which the width, by which is understood the span width of the propelling means 4 and/or the width of the tools 5-8, can be changed at the machine itself.
- both the tools in other words the devices 5 to 8, and the propelling means 4 can be preferably adjusted in the width.
- the means for adjusting the width of the tools 5 to 8 are preferably connected to the propelling means 4, one and other such that by changing the width of the propelling means 4, the width of the tools 5 to 8 is automatically changed as well, in other words the working width or the width of the concrete path 17 to be made.
- adjusting means which allow for a continuous adjustment, such that each path width can be made between a certain minimum value and a certain maximum value.
- a frame 3 which can be extended in the width, consisting of two telescopic parts 18 and 19, and of tools 5 to 8 which can be extended in the width, with parts which can be extended and/or which can be partly moved alongside one another 20-21, 22-23, 24-25 and 26-27.
- one or several of the tools 5 to 8 can be connected to the frame 3, the propelling means 4.respectively, such that an adjustment of the span width B1 of the propelling means 4 automatically results in a change of the working width B2 of the tools concerned, or thus usually the width of the concrete path 17 or vice versa.
- the above-mentioned parts 20, 22, 24 and 26 can be connected to the part 18 and the parts 21, 23, 25 and 27 can be connected to the part 19.
- Figure 3 shows a variant whereby the width adjustment is obtained as the frame 3 is supported at its angular points by means of horizontally revolvable arms 28-31 which are hinge-mounted to the frame 3 on the one hand and to the above-mentioned columns 10 on the other hand.
- the arms 28-31 hereby consist of constructions in the shape of a parallelogram, such that the caterpillars 10 or any other rolling means remain parallel in relation to one another when the machine 1 is adjusted.
- the adjustment is preferably also continuous, for example by means of drive elements for the angular setting of the arms 28 to 31, such as pressure cylinders 32 to 35, which are preferably controlled hydraulically.
- the invention also provides a possibility to adjust the working width of tools containing elements which make a back-and-forth movement in the width to the width of the concrete path 17 to be made.
- use is made to this end of a guide for such element, whose length can be adjusted.
- a telescopic guide whereby the element to be moved along this guide is suspended to said guide by means of a slide which can carry out a continuous movement over the entire guide without the transition or transitions between the different telescopic guides being an obstacle.
- This construction is especially designed to be used with a polishing device 8. An example thereof is described by means of figures 4 to 9.
- Figure 4 is a schematic representation of a concrete levelling machine 1 which is provided at the back with a polishing device 8.
- This polishing device 8 consists in the first place of a rail construction 36 which is attached to the columns 10 with which the machine 1 is supported at the back on the caterpillars 11.
- the rail construction 36 mainly consists of two solid rail construction parts, the above-mentioned parts 26 and 27 respectively, which fit in one another in a telescopic manner and which can move together with the width adjustment of the machine 1.
- the rail construction part 26 thereof is in this case fixed to the right column 10 as seen from the driving direction, whereas the rail construction part 27 is fixed on the left column 10.
- these rail construction parts can slide in and out of one another, they are each provided with a rib at the top and at the bottom, 37-38 respectively as far as the rail construction part 26 is concerned, and 39-40 as far as the rail construction part 27 is concerned.
- the running wheels 41 to 44 each have two circumferential grooves, 46 and 47 respectively, which can cooperate with pairs of ribs 37-39, 38-40 respectively, on the place where the rail construction parts 26 and 27 overlap, whereas these running wheels will only cooperate with the ribs 37 and 38 or 39 and 40 on the places where the rail construction parts 26 and 27 do not overlap.
- a motor 48 for example a hydraulic motor, which drives a chain wheel 49 cooperating with a chain 50 which is guided over chain wheels 51-52 and whereby this chain 50 is linked in a point 53 near the end of the rail construction part 27, whereas towards its other end it runs over a chain wheel 54 which is fixed in a freely rotating manner near the end of the rail construction part 26 and is subsequently bent over a chain wheel 55 fixed on the rail construction part 26 to be finally attached in a point 56 to the rail construction part 27.
- a motor 48 for example a hydraulic motor, which drives a chain wheel 49 cooperating with a chain 50 which is guided over chain wheels 51-52 and whereby this chain 50 is linked in a point 53 near the end of the rail construction part 27, whereas towards its other end it runs over a chain wheel 54 which is fixed in a freely rotating manner near the end of the rail construction part 26 and is subsequently bent over a chain wheel 55 fixed on the rail construction part 26 to be finally attached in a point 56 to the rail construction part 27.
- the actual polishing part 57 which mainly consists of a backward directed arm 58 which is freely hinge-mounted on the carriage 45 around a vertical pivot 59 and whereby between the carriage 45 and the arm 58 are provided two hydraulic pressure cylinders 60-61 which make it possible to adjust the arm 58 at a suitable angle, which can be useful in bends when the polishing part 57 could make contact with one of the caterpillars 11. It is clear that also other adjusting mean's can be used to set the polishing plate 16 at an angle.
- the arm 58 is provided towards its free end with a downward directed part 62 which bears a disc 64 at the bottom driven by a motor 63 upon which is fixed a pin 65 upon which is provided the end of a lever 66 in a freely rotating manner.
- This lever 66 is connected in a freely rotating manner at its other end by means of a pivot 67 to a lever 68 which is in turn provided in an oscillating manner underneath the above-mentioned arm 58 by means of a horizontal pivot 69.
- the second end of the lever 68 is freely hinge-mounted by means of a horizontal pivot 70 to two arms, 71 and 72 respectively, which are each provided with a bush 73-74 at their free ends.
- the arms 71 and 72 are placed at an obtuse angle in relation to one another.
- the polishing plate 16 mainly consists of a relatively long smooth plate which is longer than 1 metre, for example of the order of magnitude of 2 metres, and which has a relatively small width, which is smaller than 0.8 metres, for example of the order of magnitude of 0.3 metres, whereby the entire circumference of this plate is provided with bent edges 77-78-79-80.
- the working of the polishing plate 8 according to the invention is very simple and as follows.
- the polishing plate 16 will move back and forward over this concrete 2, whereby the plate is not only moved crosswise as a whole over the concrete 2, but whereby an additional back and forward movement is obtained in the length during said cross movement, as a result of which the concrete 2 is polished very evenly and smoothly.
- the lever 66 will carry out a swinging motion around the pivot 67 during said movement, one and other such that the polishing plate 16 is also moved back and forth over the concrete 2 in its longitudinal direction.
- the polishing plate 16 is kept constantly pressed against the concrete 2.
- the spring 81 makes sure that the weight of the polishing plate 16 and the like is somewhat compensated for, such that the polishing plate 16 always remains on top of the concrete 2 but does not penetrate it.
