Definitions

  • the invention relates to a vehicle for transporting a stack of loose stones, which has a frame which is supported by two front wheels and at least one rear wheel, means mounted on this frame for driving at least the front wheels, one in front of the front wheels the frame-mounted device for carrying the stones, which device comprises two arms which protrude forward and move sideways away from one another and can be adjusted towards one another for clamping one or more rows of stones at the bottom of the stack and means for adjusting these arms laterally relative to one another and means for Moving this facility includes.
  • the holding device for carrying stone sits vertically slidably mounted on a mast frame, which can be pivoted a little even with respect to the other parts of the frame is.
  • This construction allows the stones to be displaced in great heights, but it is complicated and in no way compact.
  • the stones are normally moved purely vertically, without the need for a support on the rear side of the holding device.
  • GB-A-965 601 describes a device for carrying stones which has a straight standing back wall. But even in this case, the device is designed to be mounted on a mast that can only be moved vertically. This device also does not include a pair of adjustable arms, but fork fingers, and the back wall mainly forms a stop for the stones when the fork fingers are inserted through openings in a stack of stones.
  • a vehicle for transporting cuboid containers is known, with a holding device which has two arms which grip the bottom container in a clamp handle and a back support. At the lower end of this holding device is a bearing, around which the loaded device can be pivoted backwards so that its center of gravity lies in the center of gravity of the axis of the front wheel.
  • the vehicle itself is a work vehicle with driven rear wheels that is hand-guided by an attendant operator and is not suitable for transporting objects as heavy as stones.
  • the proximity of the pivot point of the holding device to this leads to the fact that at the beginning of the pivoting the underside, in particular its corner area, predominantly slides horizontally on the ground and only detaches from it after a significant pivot angle has been reached. In the case of flexible suspension or tires, the pivoting may even become impossible with heavy loads, or the vehicle is thereby reset by one step, with a corresponding risk of an accident.
  • the invention is intended to create a vehicle for transporting a stack of loose stones, which has a relatively simple construction, but can be transported very quickly with the stack of loose stones can also be carried out very easily and can drive over it without risk of damage to the paving already laid.
  • the device for carrying the stones is a holding device which, in addition to the arms and the means, also has an almost flat support which rises from the bottom upwards on the back of the arms in front of the front wheels and about a horizontal axis which is in one Distance behind the support is located near the axis of rotation of the front wheels, is pivotally mounted directly on the frame, the support being inclined upwards and backwards when the device is rotated, around the rows of stones clamped between the arms and rows above them Supporting stones and the two arms for distributing the pressure of the rows of stones gripped between the arms are provided on their mutually facing side with feet, which are articulated about a vertical axis on the arms.
  • the stones can thereby be lifted in a very simple manner by simply rotating the holding device at the same time and stored stably for transport, the feet ensuring that the stones are held securely at their prescribed height in a sufficiently secure manner that parts protruding below and grinding when angled Stones are avoided. This is particularly advantageous when paving stones are loaded onto pavement that has already been laid.
  • the front wheels are rigid with respect to the frame, that is to say they cannot be pivoted, and the means which drive at least the front wheels are those which drive the front wheels separately.
  • the rear wheel is preferably a steering wheel.
  • the vehicle is very easy to steer and can turn quite closely.
  • the vehicle shown in Fig. 1 for transporting a stack of loose stones comprises a frame 1 which is supported by two rigid front wheels 2 and two rear steering wheels 3.
  • the vehicle is a self-propelled vehicle with a fuel engine 4, which is fed by an overhead fuel tank 5.
  • This motor 4 drives a hydraulic compressor 6.
  • the compressor 6 is connected via a distributor 7 on the one hand via a line 8 to an oil tank 9 and on the other hand via lines not shown in the drawing with two hydraulic motors 10 and cylinder-piston mechanisms 11 and 12, as will be described below.
  • the front wheels 2 are each driven by one of the hydraulic motors 10, which are fastened to cross members, which are parts of the frame 1. They are steered separately by a driver sitting on a seat 13 by means of two levers 14.
  • the vehicle When the two motors 10 are running at the same speed, the vehicle is traveling straight. By increasing the speed of one of the motors 10, one can steer the vehicle, also thanks to the fact that the rear wheels are steering wheels 3. The vehicle can turn very tightly and almost on the spot, without damaging any pavement that the vehicle has already laid over.
  • a holding device 15 is pivotally mounted on the frame 1.
  • This holding device 15 contains one from below top-extending, almost flat support, which consists of a frame 16 made of metal tubes and a net 17 welded thereon.
  • the underside of the frame is formed from a horizontal, hollow square tube 18 which extends in the transverse direction of the vehicle.
  • a square support tube 19 is displaceable, which carries an arm 20 at its end.
  • the two arms 20 on the two support tubes 19 extend on both sides of the support 16, 17 to the front, practically at right angles to the level of the support 16, 17. They are each provided on their mutually facing sides with two feet 21 articulated about a vertical axis , which match two rows of stones.
  • these stones are drawn in dash-dotted lines and given the reference number 22. Because the feet 21 are articulated, the pressure exerted by the two arms 20 on the rows of stones 22 is distributed evenly over the two rows, even if the row lengths are not exactly the same.
  • the two arms 20 can be moved towards and from each other by means of the two cylinder-piston mechanisms 11, the cylinders of which are fastened on top of the tube 18 and the pistons of which are connected to ends of the respective two arms 20 projecting from the rear of the support 16, 17 be pushed away.
  • the two cylinder-piston mechanisms are of course operated together, so that the two arms 20 are pushed towards or away from each other at the same time.
  • the pivoting of the support 16, 17 and thus the complete holding device 15 is effected by the cylinder-piston mechanism 12, the cylinder of which is articulated at a small distance behind the support 16, 17 on the horizontal axis 24, specifically via two horizontal arms 26 welded to the top of two profile frames, which are extend between the wheels 2 at the front of the frame 1.
  • the piston is articulated to two small arms 27 which are welded to the back of the hollow tube 18.
  • the holding device 15 can be pivoted between the position shown in FIGS. 1 to 3 and the position shown in FIG. 4.
  • the vehicle is relatively compact and easy to steer.
