Definitions

  • the invention relates to a construction machine for producing a ceiling covering for cycle paths, walkways or the like. According to the preamble of claim 1.
  • the ceiling covering must be supplemented accordingly after completion of the work. It is known to mill the edges of the ceiling covering, to pull them straight and then to close the ceiling covering of the walkway or cycle path with a paver or the like.
  • the invention has for its object to provide a construction machine for producing a ceiling covering, with the without Preparatory work for additional old coverings can be closed.
  • the old covering is milled to a predetermined width in the area of the section to be repaired and installed over the screed with the addition of new material.
  • Mechanical preparatory work in particular the cutting and straightening of the edges of the ceiling covering section to be repaired, can be completely dispensed with, since the covering is milled off beyond the edges by means of the milling and mixing unit.
  • the working width of the milling and mixing device is matched to the adjustable working width of the paving so that the ceiling covering sections to be renewed can have different widths.
  • the milling and mixing unit is preferably formed from two rolls lying transversely to the direction of travel, which are designed as milling and mixing rolls.
  • the roller lying in front in the direction of travel is ver than in its working width beyond the working width of the trailing roller adjustable vario roller designed, whereby the construction machine according to the invention can be adapted in its working width to the respective applications.
  • the working width advantageously varies between 1.2 m and 2.40 m.
  • a distribution roller is arranged between the milling and mixing unit, which distributes the mixed material mixed by the milling and mixing unit (milled old material and supplied new material) in front of the paving jack and is installed over it.
  • the chassis 1 consists essentially of a chassis 4 with a drive motor 3 arranged thereon.
  • the chassis 2 has a caterpillar drive 2 on each longitudinal side, which consists of individual steel plates with highly wear-resistant rubber treads fastened thereon.
  • the caterpillar drive 2 is provided with wheel hub motors, not shown, which are driven and controlled by a hydrostatic drive system.
  • the hydrostatic drive system is driven by the drive motor 3.
  • a bunker 5 is arranged in front of the drive motor 3 on the chassis 4, which bunker serves to hold the ceiling material to be applied.
  • the bunker 5 is open to the front and top, so that it can be loaded by a tipping vehicle approaching from the front.
  • a support frame 12 is arranged, which is fixed in height at its front end to the chassis 4 and carries a paving 7 at its rear end.
  • the height of the paving jack 7 can be adjusted, for example, via a vertical spindle 13, so that the paving thickness of the new ceiling covering can be predetermined.
  • a milling and mixing device 8 is arranged underneath the carrier frame 12 between the crawler drive 2 and the built-in jack 7, which in the exemplary embodiment shown consists of three rollers 14, 15, 16 lying one behind the other in the direction of travel.
  • the rollers 14, 15, 16 are held on their axial faces in bearing arms 17, which in turn are attached to a support arm 18.
  • the support arm is held at its front end 19 in the direction of travel 11 on the chassis 4 so as to be pivotable about a horizontal axis.
  • an adjusting spindle 20 is arranged at the rear end of the support arm 18.
  • the milling and mixing device 8 consists of two milling and mixing rollers 15 and 16 arranged one behind the other in the direction of travel 11.
  • the rollers lie transversely to the direction of travel 11, preferably at right angles and centrally to the longitudinal axis 26 of the chassis.
  • the milling and mixing roller 16 lying at the front in the direction of travel 11 is adjustable in its working width beyond the working width B of the trailing milling and mixing roller 15.
  • This adjustable roller 16 also called a vario roller, is advantageously composed of two partial rollers 116, 216 which are coaxial with one another and each have their own hydrostatic drive 21 on their mutually facing end face.
  • the partial rollers 116, 216 are to the left and right of the chassis longitudinal axis 26 at right angles to this.
  • the milling and mixing roller 15 arranged in the direction of travel 11 has its own hydrostatic drive 22 on one end face and delimits a roller gap 24 with the vario roller 16.
  • the peripheral surfaces of the milling and mixing rollers 15 and 16 rotate in the same direction Floor.
  • the rollers 15 and 16 rotate in different directions of rotation. Due to the different directions of rotation, there are 24 rectified movements of the rolls in the roll gap.
  • the milling and mixing unit 8 has a working width M (FIG. 2) which is achieved by correspondingly assigning the two milling and mixing rollers 15 and 16 to one another.
  • the partial roller 216 covers the axial width of the hydrostatic drive 22 of the trailing milling and mixing roller 15 in the direction of travel 11 with its working width T.
  • the working width B of the Milling and mixing roller 15 which results in the total working width M of the milling and mixing unit 8.
  • the vario roller 16 is axially infinitely variable in its width, as a result of which the working widths T of the partial rollers 116, 216 extend beyond the axial ends of the trailing milling and mixing roller 15.
  • the working width T 'of the partial roller 216 is such that it continues to cover the axial width of the hydrostatic drive 22 of the roller 15 in the direction of travel 11.
  • the maximum working width M1 of the milling and mixing unit 8 results from the working widths T 'and B.
  • the maximum working width M1 is slightly smaller than the maximum working width E of the jackdaw 7, which is also adjustable as a vario-jackdaw Working width is formed.
  • the milling and mixing device 8 lies between a conveyor belt 6 extending in the longitudinal direction of the chassis and the jackdaw 7.
  • the conveyor belt 6 conveys ceiling covering material from the bunker 5 of the construction machine 1 against the direction of travel 11 approximately in the middle in front of the vario roller 16.
  • On the outer circumference of the vario -Roller 16 conveying screws 27 are arranged, the pitch of which is approximately 45 °.
  • the screw conveyors 27 generate conveying movements in the direction of the arrow 28 towards the longitudinal axis 26 of the chassis.
  • the milled material of the old covering 9 is mixed together with the ceiling covering material supplied from the bunker 5 and brought together to the working width B of the trailing roller 15, in particular when the vario roller 16 is fully extended.
  • scraper plates 30 are preferably arranged at the level of the nip 24, and are located at a short distance from the floor in the direction of travel 11 behind the extended partial rollers 116, 216.
  • the scraper plates 30 guide the milled material of the old covering due to the conveying effect of the screw conveyor 27 into the working width B of the trailing roller 15, where the old covering material is intimately mixed with the ceiling covering material supplied by the bunker via the conveyor belt 6.
  • counter-rotating screw conveyors 29 are arranged on the milling and mixing roller 15, the pitch angle of which differs from that of the screw conveyors 27.
  • the screw conveyors 29 convey directions towards the longitudinal axis 26 of the chassis as well as away from it. This axial back and forth conveying of the mixture brings about a thorough mixing of the material accumulated in the nip 24 or in front of the milling and mixing roller 15.
  • a distribution roller 14 is arranged between the conveying and mixing device 8 and the built-in jack 7, the axial extension of which corresponds to that of the roller 15 and is also provided on one end face with a hydrostatic drive 23.
  • the distribution roller 14 rotates about its axis of rotation 34 in the direction of rotation 14a, which - in relation to the axis of rotation 35 of the roller 15 - is opposite to the direction of rotation 15a. Due to the opposite directions of rotation 14a, 15a, the same direction of rotation of the peripheral surfaces of the rollers 14 and 15 results in the nip 25, this direction of rotation being directed upwards away from the ground.
  • the vario roller 16 and the distribution roller 14 In relation to the direction of rotation 16a of the vario roller 16, the vario roller 16 and the distribution roller 14 have the same directions of rotation.
  • the distribution roller has screw conveyors 31 which have a pitch angle of approximately 45 °.
  • the screw conveyors 31 are arranged symmetrically to the chassis longitudinal axis 26, so that on each side of the chassis longitudinal axis 26 in connection with the direction of rotation 14a of the distribution roller 14 there is a conveying direction 32 away from the chassis longitudinal axis.
  • the rollers 14 and 15 have the same axial width and, moreover, like the vario roller 16, have the same diameter.
  • the width of the nip 24 corresponds to the nip 25; otherwise the rollers 14, 15 and 16 have approximately the same speed.
  • the distribution roller 14 can rotate at a higher speed than the rollers of the milling and mixing unit to achieve a faster distribution.
  • a different speed design is easily possible by arranging your own hydrostatic drives 21, 22 and 23. Only the partial rollers 116, 216 of the vario roller 16 are preferably driven at the same speed.
