Definitions

  • the invention relates to an extending screed according to the preamble of claim 1.
  • each screed body has a height adjustment device, which is conventional between the smoothing plate and the torque take-up device is arranged. As a result, the height adjustment device with the screed body applied to the twisting load.
  • the power arm the torque take-up device about the axis of the extension guide is relative short.
  • This relatively complex concept is also used for smaller extending screeds
  • So-called small pavers are used and are derived from the common construction principle of large ones Extending planks for large manufacturers.
  • Small paver extending screeds have a working width range between, for example, only about 1.7 m and about 3.4 m, so that the mechanical requirements here are actually lower than for extending screeds on large manufacturers.
  • the invention has for its object a screed of the aforementioned Specify type that is characterized by a structurally simple and inexpensive concept distinguished, the conception in particular on the simpler conditions should be coordinated with a extending screed for small manufacturers.
  • the height adjustment device between the torque take-up device and the extension guide of the extending screed body Since the height adjustment device between the torque take-up device and the extension guide of the extending screed body is integrated into it, it becomes of the loads rotating the screed body around the extension guide optional. On the other hand, these loads are already introduced into the basic screed body, where they originate, so that the torque pickup is a cheap large power arm around the extension guide. This allows, at least to relatively simplify the screed body and a simple, convenient to use Use height adjustment device.
  • the first support surface is, for example, the drag resistance of the screed body resulting forces exactly opposite to their direction of origin recorded and introduced into the basic screed body.
  • the rail is structurally simple on a rear arm of the screed body attached, with an intermediate distance, so that the gripping arrangement can be easily engaged and is durable.
  • the first support surface is sufficient to transfer the loads.
  • a second support surface for the gripping arrangement which is essentially parallel to the first be provided. It is important in any case that the support surfaces are roughly parallel are oriented to the adjustment direction of the height adjustment, so that the engagement between the gripping arrangement and the rail adjustment movements of the height adjustment device allows without the intervention of the torque receiving device endanger or even re-enact them.
  • the gripping arrangement expediently contains an optionally adjustable one Sliding block arrangement with sliding blocks that work in contact with the support surfaces.
  • rolling elements could also be used.
  • the Sliding contact has the advantage of extending the screed body and also allow height adjustment movements.
  • the height of the support surfaces should be so great that the sliding blocks engage in each
  • the height of the base part is maintained to a sufficient extent. This sliding intervention enables the bottom part to be adjusted without adjusting the torque take-up device to adjust parallel to itself or to tilt in any direction to do that to obtain the desired working profile of the extending screed.
  • the gripping arrangement on a cheek part of the base part is technically simple arranged.
  • the height adjustment device is located between the base part and a crossbar the extension guide of the screed body. This area offers enough Installation space so that large usable adjustment strokes can be achieved.
  • the height adjustment device should tilt inwards or outwards relative to the extension guide at least from two individually adjustable units on the Traverse exist.
  • Piston in the traverse which is connected to the base part via an articulated axis is, with the hinge axis oriented approximately parallel to the floor and perpendicular to the crossbar is.
  • the articulated axes of both units also allow the Bottom part inwards or outwards.
  • the piston and locking device are comfortable from the top of the crossbar operable here.
  • auxiliary drives e.g. mechanical, hydraulic or electromechanical type, used for this purpose become.
  • the crossbar Cover profile may be attached.
  • the screed base such as known per se, divided in the middle and the two halves around a hinge be adjustable.
  • each screed body parallel to itself to adjust yourself or relative to the extension guide on the base screed body half Tilting inwards or outwards can be done apart from the extending screed from an exactly aligned orientation of all smoothing plates, the most diverse positive ones or set negative roof profiles, parabolic profiles or W or M profiles.
  • An extending screed B according to FIGS. 1, 2 and 3 has a central screed body G and two on the rear of the Screed base body G extendable and retractable extendable screed body A.
  • the Basic screed body G is, e.g. in this embodiment, divided in the middle so that two Basic screed body halves G1, G2 are present, which are adjusted by an adjusting device 2 underlying hinge 1 are adjustable relative to each other. Every screed body A is in an extension guide S on the base plank body half assigned to it G1, G2 slidable.
  • the extension guide S consists of, for example an outer cylinder tube 8 in the basic screed body half, one guided therein Telescopic tube 7, the inner and outer cheeks 5, 6 of the screed body A is connected to an adjustment drive 4, e.g. a hydraulic cylinder, and corresponding Supports in the base screed half G1, G2. Because the extension guide S of each extending screed body A over the longitudinal center of the basic screed body G extends away, are the outer telescopic tubes 8 of both extension guides S, e.g. in the working direction (Fig. 1 perpendicular to the plane of the drawing), against each other added.
  • Each screed body half G1, G2 has a smoothing plate 3 on the underside, above its unspecified components such as screed heating, vibrators, Tamper and the like are integrated.
  • the screed body A has a channel-shaped bottom part T with a bottom-side smoothing plate 12, in the bottom part T again working components such as a heater that are not highlighted, Vibrators, tamper and the like are integrated.
  • the bottom part T stands with the crossbar Q via a height adjustment device H in connection with that shown in FIG Embodiment of two individually spaced in the longitudinal direction of the cross member Q. actuatable units 10, 11. It is possible to have only one unit.
  • Torques such as those resulting from the towing forces, and the Extending screed bodies A to twist the extension guide S will be by a torque take-up device M, consisting of a base screed body Abutment W and a gripping arrangement permanently attacking it E, introduced from the base part T directly into the base screed body E.
  • the abutment W is located as far down as possible on the back of the plank base G.
  • the height adjustment device H is between the extension guide S and the torque receiving device M provided.
  • the abutment W is an upright, e.g. on a boom 20 attached to the back of the base board body G rail 17 with the first and second, approximately vertical and mutually parallel support surfaces 18, 19 for the gripping arrangement E.
  • the gripping arrangement E is on one on the inner end face the bottom part T fixed cheek part 14 and has a plurality of sliding blocks 15 on, which can be adjusted by means of an adjusting device 16 so that they in Are in sliding contact with the first and second support surfaces 18, 19.
  • Sliding blocks 15 could also be provided with pillows or rolling elements.
  • the adjustment direction of the height adjustment device H is vertical, i.e. roughly parallel to orient the first and second support surfaces 18, 19.
  • the usable actuating stroke the height adjustment device H is dimensioned so that it is smaller than the height of the first and second support surfaces 18, 19 so that the attack of the sliding blocks 15 at each Height adjustment of the bottom part T is retained.
  • Each unit 10, 11 of the height adjustment device H has in this embodiment one guided in a cylinder 23 of the cross member Q approximately vertically displaceably Piston 22, whose relative setting position by means of a screw 24 from the top of the crossbar T is adjustable.
  • the piston 22 is in a joint with a cover plate 13 of the bottom part T, the hinge being approximately parallel to the floor and contains joint axis 25 oriented perpendicular to the crossbar T.
  • a blocking device with a blocking spindle 26 in the Traverse T may be provided. Facing the back of the screed base G. the crossbeam carries a protective or stiffening profile 21, behind which the actuating ends the spindles 24, 26 are hidden.
  • the blocking spindle 26 also acts the hinge axis 25 to the selected setting position of the piston 22 in the manner of a Lock nut.
