Definitions

  • the present invention relates to a sweeping aiding device for municipal street cleaning sweepers.
  • street sweepers are conventionally used for cleaning municipal streets and comprise a plurality of motor driven cleaning brushes, specifically designed for sweeping the street surface and collecting dirt therefrom.
  • the mentioned street sweepers are adapted to operate in an optimum manner if the street being cleaned is free and not obstructed by obstacles.
  • a walking operated provided with a broom or other sweeping instrument, can collect said dirt at a region which can be accessed by the sweeper brushes.
  • the aim of the present invention is to provide a sweeping aiding device, specifically designed for solving the above mentioned problems affecting the prior art.
  • a main object of the present invention is to provide such a sweeping aiding device allowing to a walking operator to easily and quickly collect dirt and waste materials to direct the latter to the sweeper cleaning brushes.
  • Another object of the present invention is to provide such a sweeping aiding device which does not require any great physical effort by the operator and which can also be used for a long period.
  • Yet another important object of the present invention is to provide such a sweeping aiding device which also allows to properly clean streets and sidewalks even in regions thereof occupied by parked vehicles, and this by aiding the cleaning operator by a safe, efficient and noiseless system which, in addition, can be also easily controlled.
  • a sweeping aiding device to be applied to municipal street sweepers, characterized in that said device comprises a servo-controlled articulated arm, which can be coupled to a street sweeper and comprises a windable sheath bearing, at one end portion thereof, a sweeping lance adapted to provide pressurized water and to be gripped by an operator.
  • the sweeping aiding device which has been generally indicated by the reference number 1, comprises a semiautomatic two articulated-joint arm, comprising a first arm segment 2 fixed at the middle region of the street sweeper 3 above the front portion of the tilting casing 4 thereof, through a first articulated joint 11.
  • the above mentioned arm is of a self-moving type, i.e. it can be driven in a plane parallel to the ground, and arranged at a level greater than the maximum height of the sweeper.
  • the sweeping operation is performed by using pressurized water delivered from the street sweeping machine and, to that end, the sweeping aiding device ends with a sheath 13 supplying and supporting a sweeping lance 5.
  • Said sweeping lance is driven by a walking operator 6, and allow to displace dirt and waste materials from the sidewalks 7 and from the bottom of the cars or vehicles 8 parked at the central portion of the street 9, from which said dirt and waste materials are collected by the sweeper, which in the meanwhile washes the street surface.
  • the articulated arm as is shown, comprises a second segment 10 coupled to the first segment 2 by a second articulated joint 12.
  • the two arm segments 2 and 10 in the maximally extended condition thereof, have a length larger than six meters, but a specifically designed system for winding and automatically recovering the sheath 13 allows the operator to move away, if necessary, by other three meters from the sweeper.
  • the lance 5 supporting sheath 13 slides, at the end portion of the arm, in a special supporting element 14, of a joystick type, which automatically drives the arm segment, thereby providing an operator tracking length reserve, independently from the movement direction of the operator.
  • the walking operator can perform the dirt and waste material removal operation, without considering the position of the sweeper arm.
  • the sheath 13 ends with an electric connector and a water quick fitting, allowing, as the sweeping aiding device is in an idle condition above the sweeper, to disconnect the lance 5 for storing it at any other desired location.
  • the supporting sheath 13 will be automatically wound within the arm segment 10 and will be bracketed on a side of the casing or box 4.
  • the sheath 13 is wound, by a specifically designed winding system, inside the second segment 10 on a cable holder chain 19 coupled to the aiding shoes 20, which can slide at the top in a polyethylene guiding element 21.
  • the sheath 13 projects from the second arm segment 10 through the end portion 18 comprising a control system for controlling the position and movement of said sheath, said control system comprising two potentiometers 23 and 24, each of which is provided with small rollers 25, arranged in respective orthogonal planes, thereby to transmit an electric signal to the control central unit controlling the servomotors 26 and 27 which respectively drive the first and second articulated joints.
  • said potentiometers can detect or sense the operator moving speed, so as to properly control the servomotors of the articulated arm to properly track or follow the moving operator.
  • a spotlight element having a halogen lamp, mounted on the end portion 18 of the second arm segment 10, will allow the sweeper to also operate in a night period, by diffusely illuminating from the top the working region.
  • the two arm segments are compasses-like closed, and are bracketed on the sweeper 3 by an automatic safety locking system.
  • the sweeping aiding device will be held inside the sweeper perimeter thereby meeting the maximum height values provided by the Street Code.
  • the sweeping aiding device is adapted to indifferently operate on both sides of the sweeper.
  • a selector or switch element, arranged on the cab button panel of the sweeper will allow to select the working side and then, the system controlling softer will prevent any further movements on the other side of the sweeper.
  • the rotary movements of the two arm segments are motor driven.
  • Torque limiting elements together with damping rubber section elements, arranged on the sides of the arms, will protect the equipment from accidental impacts.
  • the device bearing construction 15 is coupled, by a removable coupling means, to a fixing or attachment plate 16, rigid with the sweeper casing or box 4.
  • said sweeping aiding device anchoring plate 16 is removably coupled, by a coupling bracket, to the front portion of the casing 4 of the sweeper 3.
  • the bearing construction can be subjected to the following loads:
  • the handle 17 of the lance has integrated therein an on/off joystick electric control to allow the operator to adjust, through a knob control valve, the flow rate of the water being sprayed from the lance 5.
  • the device further comprises an independent electric panel, meeting the related CE standards, provided for driving and controlling the sweeper; it comprises: a PLC for controlling the operating and safety logic circuits; I/O cards for managing the transmitted signals; and the electric motor drives.
  • the device comprises moreover an independent pushbutton panel, mounted on the sweeper cab, and including the following control pushbuttons: on/off selector; emergency pushbutton; arm extending and withdrawing selector or switch; a selector for operating either at the right or at the left of the truck; a small panel for necessary alarms; an alarm reset pushbutton; and a lighting system on/off selector or switch.
  • the driver and walking operator can continuously communicate through a radio-wave interphone system, with an earphone for the walking operator and in a voiced manner for the driver, thereby providing a highly synchronous cooperating of the driver and operator.
  • the sweeper can also comprise, onboard, the following provisions, as necessary for operating the sweeping aiding device: electricity 24 V; voltage 24+/-15% Vcc; and useful power 0.85 kW, as necessary for power supplying the arm motors, lighting system and electronic cabinet.
  • Pressurized water is advantageously filtered and free of suspensions and has a rated pressure from 60 to 100 bars (adjustable), a maximum pressure of 110 bars and a maximum flowrate of 900 dm 3 /h, for water supplying the water spraying lance.
  • the sweeping aiding device can also perform, by small modifications, even a cleaning function, by using an air blower, having a 24 Vcc electric motor, to be coupled to the sheath in place of the sweeping lance, and can also be electrically supplied by the sheath.
  • the device can also be applied on a tank truck and can be used for washing streets and sidewalks, since it would have available great amounts of water.
  • the device according to the invention can also be applied to a salt delivery truck, thereby delivering salt on the sidewalks and under the parked vehicles, under snow and ice condition.
  • the invention provides a sweeping aiding device allowing to sweep and wash streets and sidewalks even in regions occupied by parked vehicles, aiding the operator through the use of a safe, efficient, noiseless and easily manoeuvrable system.
  • the used materials, as well as the contingent size and shapes can be any, depending on requirements.
