Definitions

  • ABSTRACT A dredging device having a mounting plate for positioning the device on a vehicle and a slidable carriage movable on the plate. Means are included for sliding the carriage along the plate and locking it in a given location.
  • This invention relates to mounted dredges which are movably arranged on a guidewhich is attached by means of a slidable carriage to a carrier vehicle and which extends laterallyto the latters longitudinal axis.
  • a clamping device designed to fix the slidable carriagein any desired position longitudinally along the lateral guide.
  • the state of the art shows mounted dredges in which the slidable carriage, which carries the outriggers and the digging tool, is clamped by means of two or more cylinders, similar to the arrangement used in parallel vises or disk brakes.
  • This known type of clamping therefore takes place by the use of tension.
  • the invention is intendedto create a clamping device that locks the device in any given location. This clamping action is achieved with simple hydraulic means and can be easily achieved as well as maintained because of its structure and because it is not vulnerable to failure.
  • a clamping device for hearing slidable carriages having mounted dredges is characterized through a perpe'ndicularly mountable plate which is held on a carrier vehicle and which has dove-tail-shaped chamfers on the upper and lower gliding pieces on the slidable carriage which grip or-extend over the upper and lower edges of the mountingplate and which come to rest against the chamfers with correspondingly arranged wear-resistant strips, as well as by hydraulic cylinders which are arranged in the vicinity of the upper-or lower edge of the mounting plate in the carriage. When power or stress is applied, the pistons of these hydraulic cylinders press against the plate and thus guarantee form locking'vclamping via the chamfers on the gliding pieces and the plate.
  • FIG. 1 is a perspective view of a dredge with a mountingplate which is shown held in aposition at the 1 tail end of a'tractor;
  • FIG. 2 is a perspective view-of a part of the mounting plate with the carriage guided on it;
  • ⁇ FIG 3 is an enlarged cross section through the mounting plate and the carriage.
  • A'mouriti'ngplate '10 isheld in position, for instance, on'the'tail end of a tractor, as shownin FIG. 1, and a slidable carriage 20 is guided in a movable manner.
  • the mounting plate consists of a welded construction with a plate 11 and with horizontally rubbing U-shaped reinforcement parts 12 which constitute a hollow frame with the plate. Providedon this hollow frame are suspension loops or other means. of attachment (not shown), in order to establish a firm connection with thecarrier vehicle.
  • On the horizontal upper and lower edges of plate there are provided chamfers 1'3 and 14,-preferably at-an angle of 45, which, considered together, give a dove-tail guide for the carriage 20.
  • The'carriage is likewise made in the form of a welded construction and consists of upper and lower gliding pieces 21 and 22, which are firmly connected with each other via bracing parts 23, 24. Furthermore,
  • Gliding pieces 21 and 22.of the carriage contain lon- 20 gitudinal grooves 27 and 28, one of whose side wall is chamfered in adaptation to the chamfers l3 and 14 of plate ll, likewise at an angle of 45, each time.
  • Interchangeable wear-resistant guide strips 29 may be attached to these chamfers of grooves 27 and 28.
  • the upper and lower gliding pieces 21 and 22 can, in each case, consist of two individual parts which constitute the lateral ends and corners of carriage '20 and which are connected to each other with the help of bracing parts 23, 24.
  • horizontal glide bushings 30 are built in, according to FIG. 3.
  • a freely movable piston 31 is guided.0ne of the end surfaces of pistons 31 is opposite the mounting plate 10 while the other end surface can be stressed hydraulically by a 4O 30.
  • a pressure-medium duct 35 is provided in that lid.
  • This duct is connected to the hydraulic power supply of the dredge.
  • FIG. 3 shows the condition in which the pistons 31 are under hydraulic tension, whereby they press against the mounting plate 10 and lock the carriage 20.
  • gliding pieces 21 and 22 come to rest against chamfers Band 14 of plate 11 with their wear-resistant strips 29 so that the carriage remains firm also when the dredgersoutrigger is swung around at an angle of If the bearing sled is to be adjusted laterally toward the longitudinal axis of the vehicle, then the hydraulic pressure in pressure chamber 32 is reduced.
  • the hydraulic cylinders constituted by glide bushings 30 andpistons 31, can be replaced by clamping screws whose rotation motion is synchronized via a common mechanical or hydraulic drive.
  • pistons 31 can also be built into the lower gliding pieces 22in order to initiate the clamping of the carriage from the lower part of built-on plate 10.
