Definitions

  • the invention relates to a self-propelled construction machine according to the preamble of claim 1 and to a method for driving a height-adjustable sealing element according to the preamble of claim 18.
  • the known road milling machines have a milling device which has a milling drum for milling the material.
  • the milled material is fed to the following truck via the rear of the milling machine.
  • stabilizers or recycler are to be distinguished, which produce by the addition of binders from a non-load bearing ground, such as a loose ground (stabilizer) or a damaged roadway (recycler) a load-bearing substructure, which for later overbuilding with a roadway suitable is.
  • a non-load bearing ground such as a loose ground (stabilizer) or a damaged roadway (recycler) a load-bearing substructure, which for later overbuilding with a roadway suitable is.
  • Road milling machines and stabilizers or recyclers have in common that the working device has a work roll and a roller housing enclosing the work roll, which is closed by at least one working direction downstream of the work roll arranged sealing member, which is also referred to as stripping.
  • the working device has a work roll and a roller housing enclosing the work roll, which is closed by at least one working direction downstream of the work roll arranged sealing member, which is also referred to as stripping.
  • road milling machines also have a sealing element arranged in front of the milling drum in the working direction, which is also referred to as a hold-down device.
  • the road milling machines have a right and left edge protection extending in the working direction, which laterally close the roller housing.
  • the sealing element In practice, the problem arises in the case of all sealing elements that the sealing element can hit obstacles in the event of unevenness. Therefore, the sealing element must be adjustable in height. This problem arises in particular in the transverse to the working direction extending front and rear sealing element. The problem of jamming arises in particular in the case of the rear sealing element, since the rear sealing element is set in the working direction and is generally equipped at the lower edge with divorced hard metal elements. This problem is further increased in the rear sealing element in that this sealing element is generally subjected to a pressing force.
  • a road milling machine with a front hold-down and a rear stripping element is for example from the EP 2 050 875 A2 known.
  • the road milling machine has a tracking element, with which the hold-down is connected by a control lever so articulated that is lifted when striking the Nach lecturorgans to an obstacle of hold-down.
  • the U.S. 4,723,867A describes a road milling machine whose Fräswalzengeophuse has a front and rear sealing element. Both sealing elements can be adjusted in height, so that the milling drum is accessible.
  • the CN 102 168 401 A describes a self-propelled construction machine, in particular road milling machine, which has a machine frame and a work roll and a roll housing enclosing the work roll, which is closed by at least one sealing element to the ground.
  • the road milling machine has a device for raising and lowering the sealing element, which has a piston / cylinder arrangement with which the sealing element can be raised or lowered.
  • a control unit regulates the hydraulic pressure in the cylinder of the piston / cylinder arrangement such that the sealing element rests on the ground with a predetermined contact force. For the regulation, the force acting on the sealing element detected vertical force component with a measuring unit that measures the hydraulic pressure in the cylinder.
  • the sealing member is raised when a vertical force acts on the sealing member, so that the hydraulic pressure increases.
  • the sealing element can be pulled with a certain contact force on the ground lying over the ground (floating position).
  • the regulation of the sealing element can react sufficiently, for example, to the change in the milling depth, which leads to a change in the measured hydraulic pressure (vertical force component).
  • the disadvantage is that the control can not respond to obstacles that exert a horizontal force component on the sealing element. When the sealing member abuts an obstacle, its Aufstandskraft with which the sealing member rests on the ground, remains virtually unchanged, since when striking an obstacle only a substantially horizontal force component acts on the sealing member. Consequently, the sealing member is not raised.
  • the sealing element is pivotally mounted about an axis which lies in the working direction in front of the milling drum.
  • the sealing element can be raised or lowered with a piston / cylinder arrangement.
  • the hydraulic pressure is adjusted so that the sealing member is pivoted against the pavement at a predetermined pressure. If the predetermined pressure between the sealing element and the road surface is exceeded, which is due, for example, to irregularities in the road surface or an increase in the cutting depth, the hydraulic pressure should be designed such that a pivoting back of the sealing element about the axis is made possible. This is to prevent the piston / cylinder arrangement blocking the sealing element.
  • the invention is based on the object to provide a self-propelled construction machine, in which the roller housing is sealed in the working direction to the front and / or rear and / or side without the risk of blockage by abutting an obstacle sealing element.
  • the invention relates to a self-propelled construction machine, in particular a road milling machine, a stabilizer or recycler, which has at least one front and / or at least one rear sealing element and / or at least one lateral sealing element.
  • a sealing element is to be understood as meaning any element with which the roller housing is closed towards the bottom. However, this does not mean that the roll housing is sealed.
  • the respective sealing element or the respective sealing elements is associated with a device for raising and lowering, which is designed such that the sealing element or the sealing elements rest with a predetermined contact force on the ground or pressed onto the ground. In a construction machine with a front and a rear sealing element, for example, two means for raising and lowering are provided.
  • the bearing force of the sealing element may be the weight of the sealing element.
  • the sealing element can be pressed with a bearing force on the ground, which is greater than the weight of the sealing element.
  • the fiction, contemporary construction machine is characterized in that the means for raising and lowering the sealing member comprises a measuring unit, which is designed such that the measuring unit measures a force acting on the sealing element when abutting the sealing member on an obstacle.
  • the means for raising and lowering a control unit, which is designed such that the control unit generates a control signal for lifting the sealing member, when the force component measured with the measuring unit is greater than a predetermined limit, so that the sealing member is raised.
  • the force measured with the measuring unit is the substantially horizontal component of force acting on the sealing member when striking an obstacle.
  • the power does not have to be determined absolutely. Rather, it is sufficient if the force is determined quantitatively. Also, the force does not have to be measured directly in its actual physical unit, but can be measured across any physical principles in another physical unit, such as pressure, displacement, or the like, if these physical quantities were easier to detect.
  • the advantage of the sealing element according to the invention is that obstacles in the working direction of the construction machine can be recognized by the fact that the force acting on the sealing element exceeds a limit value. If this is the case, the sealing element is raised automatically. The sealing element is raised only until the measured force is below the limit again. In this case, it is assumed that the obstacle has been overcome and can be changed back to the original operating mode or a preselected other operating mode.
  • the limit value for the measured force should be such that the sealing element is not raised even at very small forces.
  • the sealing member may remain in the raised position. For example, the sealing member remains in the raised position when the obstacle is a step. However, the sealing element can also lower again when the obstacle is not a step.
  • the means for raising and lowering the sealing element can, for example, be returned to the Return floating position when the measured force falls below the specified limit again. Then, the sealing element can move automatically down when the height of the terrain decreases, ie the sealing element can then follow the contour of the terrain again.
  • the means for raising and lowering the sealing member may also switch to a preselected other operating mode when the measured force falls below the predetermined limit again, z. B. in an operating mode in which the sealing member is supported by a restoring force is lowered.
  • control unit generates a second control signal when the force is less than the predetermined limit, such that the raising and lowering means switches to an operating mode in which the sealing member can maintain or lower its position.
  • the lowering of the sealing element can be done solely under the action of gravity or be supported by the means for raising and lowering the sealing member with an additional restoring force. The only decisive factor is that the sealing element rests again on the ground with the given contact force.
  • the means for raising and lowering the sealing member comprises one or more piston / cylinder assemblies, the cylinder articulated to the machine frame and the piston articulated to the sealing member or its cylinder hinged to the sealing member and the piston articulated to the machine frame are connected.
  • the piston / cylinder arrangement can be operated hydraulically or pneumatically. But it is also an electric motor drive possible.
  • the assemblies required for this purpose belong to the state of the art.
  • the automatic lifting or lowering of the sealing element relieves the machine operator of the construction machine. Furthermore, the stability of the machine is improved and a constant feed ensured, since there is no risk that the machine breaks loose from obstacles. In addition, the wear of the sealing member is reduced.
  • the control of the sealing element according to the invention can always be in operation during operation of the construction machine or can also be switched off by the operator, so that the raising and lowering of the sealing element can be controlled manually.
  • a further preferred embodiment of the invention provides a stop element, in particular on the front or rear sealing element, which extends beyond the lower edge of the sealing member downwards.
  • the stop element is preferably a plate-shaped element which extends across the width of the sealing element extends. But it is also possible that the stop element extends only over part of the width of the sealing element.
  • an upper portion of the stopper member is fixed to the sealing member under a resilient bias, so that the stopper member when striking an obstacle from a first position in which the upper portion of the stopper member to the sealing member is applied, is moved against the resilient bias in a second position in which the upper portion of the stop member projects from the sealing element.
  • the stop element can be guided either linearly guided or pivotally mounted on the sealing element. It is crucial that the stop element changes its position, so that the impact with an obstacle can be detected.
  • the upper portion of the stop element is displaceably guided on an axis which is perpendicular to the plane of the sealing element.
  • the stop element can also be guided on an axis extending obliquely to the plane of the sealing element.
  • the guide of the stop element on the sealing element may comprise at least one guide pin which extends through a bore in the stop element.
  • a plurality of guide pins distributed over the width of the sealing element are provided.
  • the guide pin preferably has a screw thread, and the stop element is preferably screwed with a screw, wherein a spring is arranged between the screw and the stop element, so that the stop element is resiliently biased against the sealing element. By turning and loosening the screw, the resilient bias can be adjusted.
  • the measuring unit has at least one sensor which detects the position of the stop element and which is preferably a distance sensor, with which the deflection or displacement of the stop element when striking an obstacle is detected can.
  • the distance sensor may be a contact switch, which is actuated by the stop element.
  • the roller housing is closed in a further preferred embodiment of the invention by two in the working direction of the construction machine behind the work roll rear sealing elements, wherein two means are provided for raising and lowering of the sealing member, so that the two sealing elements are lifted when hitting an obstacle independently can.
  • the sealing elements may each extend over half the working width of the work roll.
  • Each sealing element is again associated with a stop element which detects the impact force on an obstacle.
  • the embodiment with two sealing and stop elements has the advantage that when an obstacle occurs, only one of the two sealing elements is lifted, so that the roll housing remains closed on the other side. This is particularly advantageous when cornering the construction machine, in which the risk of striking the outside or inside the curve stop element is at an obstacle.

  • the hold-down or edge protection is in a floating position, so that the hold-down or edge protection rests on the ground with a predetermined contact force.
  • the hydraulic valve 46 of the hydraulic unit connects in the floating position via the cylinder connections connected to the hydraulic lines 47, 48, the upper and lower cylinder chamber 45A and 45B of the hydraulic cylinder 45 for raising and lowering the hold-down or edge protection with a hydraulic tank, not shown, so that the chambers not the system pressure to be applied.
  • the hydraulic valve 46 is a 4/3 way valve.
  • the hydraulic lines leading to the valve are in Fig. 11 for the sake of simplicity not shown.
  • the piston can move in the cylinder, so that the Downholder or edge guard moved downwards due to its weight. At the same pressure in both cylinder chambers, this movement can be supported downwards with a corresponding formation of the effective contact surfaces of the hydraulic cylinder, when both chambers are acted upon in the floating position with a pressure, but preferably not equal to the system pressure.
  • the hydraulic valve 46 By switching the hydraulic valve 46, the one or the other hydraulic line 47 48 can be acted upon by the system pressure (pressure line) or connected to the tank (tank line), so that the piston is moved up or down.
  • the actuation of the hydraulic valve 46 takes place in dependence on the measured impact force with the control unit, which in Fig. 11 not shown.
  • the control unit When hitting an obstacle, the control unit generates a first control signal for driving the hydraulic valve 46, so that the lower cylinder chamber 45B to the pressure line and the upper cylinder chamber 54A are connected to the tank line, whereby the hold-down or edge protection is raised. If the measured force is below the predetermined limit, the control unit generates a second control signal, so that the hydraulic valve 46 is switched back to the floating position, which in Fig. 11 is shown, so that the hold-down or edge protection drops again.
  • An alternative embodiment provides that the hydraulic valve 46 connects the upper cylinder space 45A to the pressure line and the lower cylinder space 45B to the tank line, so that the hold-down or edge protection is pressed down until the hold-down or edge protection impinges on the floor. Only then does the control unit switch the hold-down back into the floating position.
  • Fig. 12 shows the hydraulic circuit diagram of another embodiment of the hydraulic control.
  • This embodiment differs from the embodiment Fig. 11 in that two cylinder-piston arrangements 49 and 50 are provided for raising and lowering the sealing element, not shown.
  • Another difference lies in an additional hydraulic unit 51 with which a defined pressure force, which is greater than the weight of the sealing element but less than the maximum working force of the respective piston-cylinder arrangement, is exerted on the sealing element.
  • This pressure force, with which the sealing element is pressed onto the ground proves to be particularly advantageous in a scraper, as a Scraper should remain in contact with the ground even when it is uneven.
  • the upper cylinder chambers 49A, 50A of the two piston-cylinder assemblies 49, 50 are short-circuited via a first hydraulic line 51 and the lower cylinder chambers 49B, 50B of the piston-cylinder assemblies 49, 50 via a second hydraulic line 52.
  • a third hydraulic line 53 leads from the first hydraulic line 51
  • a fourth hydraulic line 54 leads from the second hydraulic line 52 to a hydraulic valve 55.
  • the third hydraulic line 53 with a tank line (not shown) and the fourth hydraulic line 54 with one not connected pressure line connected.
  • the control unit not shown, actuates the hydraulic valve 55.
  • the ends of the third and fourth hydraulic lines 53, 54 are closed, for which purpose the hydraulic valve in the in Fig. 12 shown position is brought.
  • the third hydraulic line 53 is connected to the pressure line 56 and the fourth hydraulic line 54 to the tank line 57 of the additional hydraulic unit 51, so that the hold-down is pressed with the predetermined pressure force to the ground. Since the pressing force should be less than the maximum working force of the piston-cylinder assembly, the pressure in the pressure line 56 is less than the system pressure with which the piston-cylinder assemblies are actuated. In the detection of an obstacle, the control unit, not shown again generates a control signal for actuating the hydraulic valve 55 such that the hold-down is raised until the obstacle is overcome.
  • Fig. 13 shows in a highly simplified schematic representation of an embodiment of the control of an overload protection for a scraper 58, a hold-down 59 and an edge protection 60.
  • the scraper, hold-down or edge protection is assigned in each case a measuring unit 58A, 59A, 60A, each via a signal line 61 with a central control and evaluation unit 65 is connected.
  • the control and evaluation unit 65 controls, via signal lines 62 in response to the impact force measured with the respective measuring unit 58A, 59A, 60A, the hydraulic valve 58B, 59B, 60B associated with the wiper, hold-down or edge protector with which the wiper, hold-down device and edge protector assigned piston-cylinder arrangement is actuated in Fig. 13 not shown.
  • an operating unit 63 is provided, the is connected via a data line 64 to the control and evaluation unit 65. With the operating unit 63, the operator can turn off the automatic overload protection and adjust the sealing elements 58, 59, 60 by hand in height.
