Definitions

  • the invention relates to a hand-held, self-propelled orsforschreitendes work equipment, such as a vibrating plate, a vibrating roller, a rammer and the like for soil compaction, according to the preamble of claim 1.
  • Small building, self-propelled or self-propelled work equipment for soil compaction of the aforementioned type are controlled by an operator who runs with the implement, by means of a guide member in the direction of movement and operated with respect to the device functions.
  • the guide element is usually designed as a height-adjustable drawbar, on the tiller head, the control and operating elements are arranged.
  • the guide elements Since vibrations emanate from such implements, especially in dynamically compressing machines, the guide elements must be made vibration-damped.
  • elastic materials preferably the use of so-called rubber-metal compounds, has proven.
  • Such elements have good damping properties, in particular under shear stress.
  • a metallic component additionally be used, which can receive the guide element (drawbar) in a slot-shaped recess. If steering forces are transmitted in such an arrangement, the guide element engages in each case on the side surfaces of the recess and transmits the steering forces directly.
  • the disadvantage is that when applying steering forces in each case the decoupling of the vibrations of the implement is canceled. Further disadvantages are that the additional guide part increases the device costs and only works in a limited angular range.
  • connection of the guide element with the damping elements also forms the adjusting device for the guide element.
  • a desirable adaptation of the adjustment angle of the guide element to ergonomic conditions makes it necessary to solve the fixed connection of the guide element with the damping elements and to fix it again after readjustment. Otherwise, an adaptation of the position can be achieved only with appropriate length of the guide element by applying external forces and concomitant torsion of the damping elements.
  • the existing technical conditions allow either an optimized design with regard to vibration damping or increased mobility of the guide element.
  • the object of the invention is therefore to propose a guide element for hand-held implements, which is adjustable to an ergonomic position and easily readjusted, can be quickly moved from the working to a non-dangerous position in case of dangerous situations, folded for transporting the implement and can be secured, a good vibration damping allows without affecting the controllability of the implement adversely, and can continue to run robust and inexpensive.
  • a connection to the guide element is made on the implement at four points.
  • the four connection points are preferably distributed so that a rectangular arrangement is created.
  • a damping element is arranged in each case.
  • the central axis of the damping elements is placed so that each two damping elements are arranged coaxially to each other.
  • connection points can be arranged on the frame of a working device, on an additional subassembly thereof or on an intermediate component.
  • the damping elements are connected to a console.
  • the console covers the entire arrangement of the damping elements.
  • a suitable for receiving a guide member assembly is arranged at the top of the console.
  • the guide element is connected via said assembly to the console and thus to the implement.
  • this compound is articulated.
  • the guide element which may be designed as a drawbar or guide element is connected in a preferred embodiment by a hinge to the console.
  • the guide element from the working position can be folded upwards and is fixed in this position (transport position) by a securing element.
  • securing elements all suitable technical means can be used, with pins, screw, bar, Rastindizes or brackets are preferred.
  • a stop In the working position of a further embodiment according to a stop additionally be arranged. This serves to fix the ergonomically favorable height. It is possible to adjust the stop adjustable. This gives the possibility to customize the working position of the guide element.
  • Another embodiment uses a stop whose end position determining elements is additionally designed with damping elements and / or the stop itself damped. Likewise, damping elements can be arranged on the contact region of the guide element. In this way, the vibration damping of the guide element is further improved and at the same time an unwanted noise between the guide element and stop can be avoided.
  • the overall arrangement makes it possible, with suitable dimensioning, to arrange the damping elements in such a way that steering forces act uniformly on all four damping elements and no overloading occurs.
  • a rigid connection between the guide element and implement is unnecessary.
  • a decoupling of the vibrations of the implement is achieved via the damping elements, which are almost exclusively claimed to thrust.
  • the foldable or pivotally designed guide element makes it possible that a space-saving rest or transport position can be made possible with simultaneous fixation of the guide element. In dangerous situations beyond the guide element can be folded up. By a continuous adjustment of a stop, which is additionally provided with damping devices, an ergonomically favorable position of the guide element can be achieved.

  • Fig. 2 a perspective view of a guide element in a working position
  • Fig. 3 a cross section through a detail of the guide element
  • Fig. 4 a perspective view of the guide element according to Fig. 2 in a folded position
  • Fig. 5 a perspective view of the guide element in a transport position
  • FIG. 10 illustrates a self-propelled dynamic self-propelled implement 1 shown schematically as a truncated block, which is operated and operated by an on-the-walk operator, for example, a vibratory plate, a unicycle vibration roller or a double vibration roller.
  • an on-the-walk operator for example, a vibratory plate, a unicycle vibration roller or a double vibration roller.
  • At its frame are four connection points, each with a bearing 2, 2 'for a hand-held guide element (drawbar) 15 (FIG. Fig. 2 . 4 . 5 ) for the operator.
  • the bearings 2, 2 ' are arranged in the vertices of a rectangle.
  • Fig. 1 shows, in each case two bearings 2, 2 'on machine-side bearing blocks 8 are present. They are provided with fastening bolts 5 for supporting damping elements 6, via which the connection of the guide element 15 to the working device 1 takes place.
  • the damping elements 6 are aligned in pairs along imaginary transverse axes 4, 4 ', which run parallel to the transverse direction of the implement 1.
  • the distance of the bearings 2, 2 'along the transverse axes 4, 4' is chosen as large as possible.
  • Fig. 2 is with the damping elements 6, the transmission of vibrations generated by the implement 1, as far as possible prevented on the guide member 15.
  • the guide member 15 is formed as a drawbar, which is pivotally articulated in its base on a console 7 for adjusting the working height and taking a transport position. At her tiller head she has guide bracket and controls 16.
  • the console 7 has the function of a rigid base frame to accommodate all necessary for attachment and articulation of the guide member 15 elements.
  • the console 7 there are two further parallel bearing blocks 11 with a total of four counter-bearings 21, 21 'to the machine-side bearings 2, 2'.
  • the connection of a machine-side bearing 2, 2 'and a console-side abutment 21, 21' takes place in each case with one of the damping elements 6.
  • the four damping elements 6 are designed as rubber buffers with metal discs 9 on both end sides. They rest with their inner end faces on the bracket-side bearing blocks 11 and with their outer end faces on the machine-side bearing blocks 8 and are held over the bolts 5, which are passed through the damping elements 6 for receiving in the abutments 21, 21 '. In the longitudinal direction of the guide element 15, the damping elements 6 have a relatively low rigidity.
  • the longitudinal axis of the guide element 15 extends transversely to the transverse axes 4, 4 '. Furthermore, the base point of the guide element 15 lies between the transverse axes 4, 4 '. Thus, there are two bearings 2, 21 above the foot and the other two bearings 2 ', 21' are located below the foot. By this arrangement it is achieved that all four damping elements 6 and the associated bearings 2, 2 '; 21, 21 'are evenly loaded by the weight of the guide bracket 15. The damping elements 6 are predominantly subjected to thrust, so that a high load capacity and service life is achieved. Despite the good vibration isolation and good controllability of the implement 1 is guaranteed.
  • the hinge 14 is arranged for the guide member 15.
  • the pivot axis runs parallel to the transverse axes 4, 4 ', so that by pivoting the guide element 15 according to arrow 12, the working height can be varied by the operator.
  • a minimum height can optionally be adjusted with a set screw 29 which is attached to the console 7.
  • the guide element 15 is extended at its base by an opening 26 in the bracket 7 through an arm 23, at the end of a stop 27 is arranged, which cooperates with the adjusting screw 29.
  • the pivoting range of the arm 23 is limited by the end of an adjusting screw 29 which is guided in a thread 31 guided on the console 7 by hand via a rotary knob 30.
  • the guide member 15 is supported by its own weight on the arm 23 at the Adjusting screw 29 off. A pivoting of the guide member 15 via the joint 14 upwards is possible without hindrance, so that it is easily folded up, for example in a dangerous situation.
  • an elastic stop buffer 28 is arranged, which further reduces the attenuated by the resiliently sprung console 7 vibrations of the machine. Due to this double damping a particularly good vibration isolation is achieved. Since the stop 27 and the adjusting screw 29 are located in front of the pivot axis of the guide element 15 and partially below the console 7, they are also well protected against mechanical damage during construction site operation and during transport.
  • FIG. 2 . 4 and 5 show a latch 17, with which the guide member 15 further in at least one further working position according to Fig. 4 locked and can be fixed in a transport position, the in FIG. 5 is shown.
  • the latch 17 is fixed in the swung-up rest position via a clamping bracket 18 on the guide member 15, which is the case during normal operation.
  • the latch 17 has two spaced locking recesses 24, 25 which define the further working position and the transport position.
  • Fig. 4 illustrates how the latch 17 is folded down and the first latch recess 24 is hooked to a console-side pin 32. This Verrieglung the guide member 15 in the other working position is then made when the operator wants to exert greater forces for pushing or pulling on the machine.
