Definitions
- the invention relates to a device for milling off floor surfaces, in particular roadways, according to the preamble of claim 1.
- Such devices are also referred to as front loader milling.
- a front loader milling machine is known for example from DE 39 03 482 AI.
- the known milling machines have a self-propelled chassis with a pair of front wheels and a pair of rear wheels.
- the chassis carries a machine frame in which a milling drum is mounted transversely to the direction of travel.
- the milling drum is generally surrounded by a housing in which the wall pointing in the direction of travel is designed as a cover plate with a passage opening for the milled material.
- the material processed by the milling drum is thrown off the milling drum onto a first conveyor belt, which the processed material on the - 2nd
- the milling drum is equipped with cutter tools that make up a conveying helix 'which transports the milled material to fürerieso réelle of Abdeckschildes.
- the first conveyor belt in front of the milling drum can easily be damaged due to breaking open base plates, the repair of the conveyor belt requiring the removal of the conveyor. Removing and installing the conveyor is very laborious and time-consuming. Furthermore, several people are required to carry out this work.
- the invention is therefore based on the object of developing a device of the type mentioned in such a way that the risk of operational malfunctions is considerably reduced.
- the invention advantageously provides that the end of the conveying device on the milling drum side is mounted in a belt shoe attached to the machine frame so that it can be adjusted in height, and that the belt shoe and the conveying device form a rigid unit that cannot be pivoted relative to one another.
- the belt shoe and the conveyor device can therefore not move relative to one another, as a result of which no processed material gets jammed between the belt shoe and the conveyor device 3 -
- the belt shoe is pivoted relative to the machine frame together with the rear end of the conveyor mounted in it.
- the conveyor device is preferably detachably mounted in the rear region of the belt shoe facing the milling drum, the position of the belt shoe relative to the conveyor device being fixed by the storage of the conveyor device and by at least one connecting strut between the belt shoe and the conveyor device.
- the connecting strut ensures that the belt shoe cannot move relative to the conveyor.
- At least one piston-cylinder unit is arranged as a lifting device between the machine frame and the band shoe.
- the belt shoe can be raised in the vertical direction, for example to overcome obstacles.
- the piston-cylinder unit cannot push the strap shoe down, but can only lift it when necessary. Otherwise, the belt shoe with the conveyor can move freely upwards.
- two link arms which are connected to one another in an articulated manner guide the strap shoe to the rear end of the conveyor device, the first link being articulated on the strap shoe and the second link on the machine frame.
- the handlebars ensure exact path guidance of the belt shoe and the conveyor - 4 -
- the unit is pivoted about the point of support of the conveyor in the shaft of the machine frame.
- the links and / or the connecting strut are arranged on both sides of the band shoe.
- the double arrangement of the handlebars and the connecting strut on both sides of the belt shoe causes the rear end of the conveyor and the belt shoe to be guided precisely along a predetermined path.
- the double arrangement of the connecting strut increases the torsional rigidity of the unit formed from the belt shoe and the conveyor.
- the links articulated on the machine frame are coupled via a connecting rod.
- the connecting rod synchronizes the movement of the handlebars on both sides, so that an exact parallel guidance of the strap shoe is ensured with the rear end of the conveyor.
- the handlebar can be bent in the form of a toggle lever, the connecting rod being mounted in the knee area.
- the mounting of the connecting rod in the knee area improves the power transmission due to the lever ratios.
- the belt shoe has a transversely extending protective shield to protect the conveyor belt of the conveyor.
- the protective shield prevents sharp-edged material from damaging the conveyor belt. Stops for the deepest and / or foremost position of the belt shoe are arranged on the roller box. The stop for the lowest position of the belt shoe limits the downward pivoting movement of the unit formed by the belt shoe and the rear end of the conveyor. Another stop for the foremost position of the belt shoe prevents a collision with the roller box. Nevertheless, it is possible to raise the strap shoe by up to 300 mm from the lowest position, the strap shoe and the conveyor being pivoted only slightly.
- the underside of the band shoe is formed by a grate made up of several grate bars running parallel in the direction of travel.
- the grate serves both as a hold-down and as a sliding shoe.
- a hold-down device is arranged on both sides of the belt shoe on the edge facing the milling drum, so that the belt shoe extends over the entire width of the milling drum.
- 1 shows a device according to the invention for milling off floor surfaces
- 2 shows a schematic representation of the position of the band shoe within the machine frame relative to the milling drum at maximum milling depth
- Fig. 3 shows the position of the band shoe with minimal milling depth
- Fig. 4 is a plan view of Fig. 1 along the line IV-IV.
- a device for milling off floor surfaces 2, in particular roadways made of asphalt, concrete or the like. with a chassis 4 which carries a machine frame 6 and a milling drum 8 which is mounted on the machine frame 6 and which extends transversely to the direction of travel of the chassis 4 is shown in FIG. 1.
- the milling depth is adjusted using the height adjustment of the rear wheels.
- Such machines are also referred to as front-loading milling machines because they transport the milled material forward in the direction of travel onto transport vehicles.
- a first conveyor device 10 with a conveyor belt 12 is arranged, which is arranged at an angle of inclination in a shaft of the machine frame 6 and transfers the milled material to a second conveyor device 14 with a further conveyor belt 15.
- the second transport device 14 can be adjusted in height by means of an adjustable inclination angle and can additionally be pivoted laterally by, for example, ⁇ 30 °, so that standing transport vehicles can be loaded next to the lane of the front loader milling machine. - 7 -
- the milling drum 8 is surrounded by a roller box 18, in which the wall pointing in the direction of travel has a passage opening 22 for the milled material.
- the passage opening 22 always has the same position relative to the milling drum 8, even with different milling depth settings.
- the milling drum 8 is provided with helically arranged chisel tools, which are arranged in such a way that the milled material is transported to the passage opening 22 in the drum box 18.
- a strap shoe 16 is attached to the machine frame 6 so that it can be adjusted in height.
- a piston-cylinder unit 17 attached to the machine frame 6 is provided for the height adjustment of the band shoe 16. With the aid of this piston-cylinder unit, the belt shoe can be raised in the vertical direction, for example in order to overcome obstacles.
- the band shoe 16 cannot be pressed down, but can only be raised if necessary. When the milling depth is increased, the position of the band shoe 16 adjusts itself automatically due to the ground contact.
- the belt shoe 16 receives the end of the conveyor 10 on the milling drum side.
- the mounting of the rear end of the conveyor device 10 is a fixed point between the belt shoe 16 and the conveyor device 10.
- connecting struts 20 are provided on both sides, which prevent the belt shoe 16 from pivoting relative to the conveyor device 10.
- the belt shoe 16 consists of a grate 28 parallel to the floor, which serves as a hold-down device and as a sliding shoe.
- the grate 28 consists of a plurality of grate bars 32 aligned parallel to the direction of travel.
- the grate 28 is delimited laterally by vertical side walls 33.
- a front plate 35 extends approximately parallel to the conveyor belt 12 of the conveyor device 10.
- a protective shield 34 is arranged to protect the conveyor belt 12, which prevents the belt 12 from being damaged by sharp-edged material .
- a sign 42 inclined slightly in the direction of travel is recessed in a U-shape in the upper region in order to form a passage opening for the processed material.
- the roller box 18 surrounding the milling drum 8 is, as can best be seen in FIG. 4, complementarily recessed and has a passage opening 22 for the processed material.
- One end of the piston-cylinder unit 17 is hinged to the side walls 33 of the band shoe 16, the other end of which is attached to the machine frame 6.
- the piston-cylinder unit 17 runs approximately parallel to the connecting struts 20 and serves as a lifting device for the structural unit formed from the band shoe 16 and the conveyor device 10.
- a first link 24 is articulated on the side wall 33 and is articulatedly connected to a second link 26.
- the second link 26 is in turn articulated on the machine frame 6.
- the second link -26 is bent in the form of a toggle lever and in the joint area via a connecting rod 30 with the corresponding second link 26 on the other side 9 -
- the connecting rod 30 thus synchronizes the parallel guidance of the strap shoe 16 on both sides of the strap shoe.
- the piston-cylinder unit 17 and the connecting strut 20 are also provided on both sides of the band shoe.
- the parallel guidance of the strap shoe caused by the links 24, 26 enables the shield 42 to perform only a slight pivoting movement, which is limited at the bottom by means of a projection 44 projecting in the direction of travel.
- the projection 44 bears against a stop 36 in the lowest position.
- Another stop 38 on the roller box 18 limits the movement of the belt shoe 16 in the direction of the milling drum 8.
- the band shoe 16 can carry out a total stroke of approximately 300 mm.
- a hold-down device 40 is provided on the rear edge, so that the belt shoe 16 with the hold-down device 40 arranged on both sides covers the entire width of the milling drum 8.
- the rear end of the conveyor 10 on the bearing must be detached from the belt shoe and the upper ends of the connecting struts 20 must be detached from the conveyor. In this way, the conveyor 10 can be quickly released from the belt shoe 16, so that repairs and maintenance work can be carried out in a very short time.
