Definitions

  • the present invention relates to a scanning device for a vehicle road, sweeper type automobile or towed chassis. It also concerns vehicles fitted with such a device.
  • Urban or industrial automobile sweepers of known type have two rotating brushes on the front or on the side, adjustable around a passing vertical axis.
  • Each broom is connected to the front part of the vehicle by means of a support formed by two arms articulated around a vertical axis.
  • a suction nozzle is placed under the vehicle chassis, set back from the brushes, and communicates with a tank receptor.
  • the brushes bring the waste and dirt to the center of the vehicle, so they can be sucked in through the nozzle then sent into the tank.
  • the covering of the roadway by the brushes is imperfect. of the dirt can pass between the nozzle and the brushes and thus not be sucked.
  • the device may be damaged or distorted.
  • One of the solutions proposed consists in mounting a scanning device additional at the front of the vehicle, called the third broom. It is in most cases completely independent of the dual sweep placed near the waste suction means. He has for function of bringing the waste which is too far away double brush.
  • the third broom moves in the horizontal plane, from left to the right.
  • the means used to control it, whether mechanical, electric, hydraulic or pneumatic, must be separate from those to control the double brush.
  • the range of motion of the third broom is a source of additional cost, and also of danger for passers-by who risk being struck by the mechanical elements of the structure. These mechanical elements being exposed to shocks, the assembly is weakened, resulting in a maintenance cost most important.
  • This assembly also makes it possible to separate the additional brush from the drive mechanism.
  • the broom being held resiliently, it offers less resistance to possible shocks.
  • US-A-4,754,521 shows a scanning device for road vehicle comprising several brushes mounted under the chassis of the vehicle and whose position relative to the surface to be treated is adjustable.
  • a first broom is placed at the rear of the vehicle, near the means and is fixed in position after adjustment.
  • a second broom, movable in the horizontal plane, is disposed in front of the first brush.
  • the two brushes are hinged together by a parallelogram structure.
  • Document DE 91 15 578 U describes a scanning device composed of two identical sets arranged symmetrically on either side of the longitudinal axis of the vehicle. Each set has a broom main and an additional movable broom, which is hinged to the broom main via an arm. Means are provided for the automatic folding of the additional broom in the event of accidental contact with an obstacle.
  • the present invention proposes to remedy these drawbacks by realizing a scanning device for road vehicle allowing a precise adjustment of the inclination, spacing and height of each brushes, so as to cover an area beyond the vehicle size while avoiding the consequences resulting from frontal or lateral impacts and ensuring optimal waste suction.
  • This object is achieved by the association in a scanning device of a first brush fixed in position after adjustment and a second mobile brush connected to the first by a parallelogram structure, cooperating with folding means of said movable broom comprising a compass gas and a jack.
  • the device according to the invention is characterized by the specific arrangement brushes at the front of said vehicle, and more particularly by the support structure of the movable broom.
  • the device may include two sets identical of two brushes, arranged symmetrically on either side of the longitudinal axis of the vehicle.
  • the scanning device comprises two sets of brushes (1, 2) and (1 ', 2'), mountable under the vehicle chassis, the first broom of each set being placed at the rear in the direction of movement of the vehicle, near the suction means, and the second upstream from the previous one.
  • the assembly is permanently mounted under the chassis of a road vehicle, in the immediate vicinity of the suction means.
  • the brushes are mounted on a structure comprising means for adjustment in three directions, so that each brush can be oriented as required forward or sideways, and in height.
  • the aim of the forward adjustment is to position the trim of the brush by ground level and is in principle done once and for all, by by means of ball joints (4) acting on the axis (3) of the brushes.
  • a parallelogram adjusts the tilt forward.
  • the axis (3) is substantially perpendicular to the ground.
  • the height adjustment is carried out in a conventional manner by means of a cylinder and a joint.
  • the lateral adjustment allows to sweep a portion of roadway if necessary exterior which would not be exactly in the same plane as the whole of the track, for example an inclined gutter.
  • the rear brushes (1, 1 ') are arranged near the means suction (not shown) and are interconnected by two bars lateral (8, 9), the lower bar (8) being fixed and the upper bar (9) being provided for adjusting the inclination of the brushes (1, 1 ') by means of, for example, inverted pitch ball joints.
  • these two brushes are fixed in position, after initial adjustment of their inclination as explained above.
  • the brushes (2, 2 ') located on the front of the device are movable parallel to the ground.
  • FIGS 2 and 3 illustrate the operation of the brushes.
  • the device as shown in the figures has four brooms, but is actually made up of two sets identical, perfectly symmetrical around the longitudinal axis of the vehicle.
  • Each broom advantageously consists of a fixed rotating brush on an axis (13), substantially perpendicular to the ground.
  • the brush (10) of the first brush (1) is positioned at the rear of the device, in the direction of movement of the vehicle and near the suction means.
  • the brush (10) is connected by a joint (18) to a parallelogram (19) controlling the lateral inclination of the brushes (1, 2) by means of two arms (17 ', 17 ").
  • the assembly formed by the arms (17 ', 17 ") is, as the case may be, directly connected to the means for fixing the device to the chassis of the vehicle, when the device has only one right or left scanning set, or the corresponding joint on the brush located opposite, when the device has two symmetrical assemblies on either side of the axis longitudinal of the vehicle.
  • the brush (20) of the second brush (2) is positioned in front of the brush (10) of the first brush (1).
  • a cylinder (15) also makes it possible to adjust the lateral inclination of the brush (20).
  • a transverse arm (26) is mounted at one of its ends on the axis (23) of the brush drive motor (20).
  • the other end of said arm is connected to a parallelogram (27), which cooperates with the cylinder (14) of the rear brush (10).
  • the parallelogram (27) makes it possible to adjust the difference height between front and rear brushes, depending for example their respective degree of wear or the condition of the roadway.
  • the brush (20) is folded inwards, while keeping a movement parallel to that of the vehicle.
  • the device adopts the position shown in the figure 2.
  • the brush (20) is spread and protrudes from the chassis of the vehicle towards outside.
  • the initially defined position is kept on.
  • the surface swept will be particularly wide, since it will cover the area trapezoidal formed by the four brushes (10, 10 ', 20, 20').
  • the device according to the invention provides means for automatic folding the movable brush (20) under the chassis of the vehicle, for example in the event of shock causing contact between the front brush and the rear brush.
  • said means can comprise a gas compass (30), connecting the axis (23) of the brush drive motor (20), at the joint (18) near the axis of rotation (13) of the brush (10).
  • the brushes (10, 20) are rotated in the direction A - B, i.e. from outside to inside.
  • the rotation of the brushes causes a withdrawal movement and thus eliminates any risk of shock that could damage or distort the device.
  • the compass (30) operates under a very low control pressure, so that in the event of impact, the brush (20) pushes the cylinder (14) on the arm (26) while folding against the other brush. By the meaning of rotation of the brushes, this kinematics then causes the reopening of the cylinder (14) and the corresponding withdrawal of the brush (20) under the chassis.
  • the scanning device brings many advantages, due to the characteristic layout of the brooms which compose it.
  • the scanning area is much larger than in the conventional devices.
  • the device is light and does not obstruct vehicle performance and safety.
