Definitions

  • the invention relates to a linking system for assembling self-propelled hand-operated machines of various types, such as Excavators for excavations, piling drills or other support and anchoring means, oleodynamic impact drills, or any other oleodynamically powered hand tool, using only a single support structure that functions as a power unit.
  • the inventive device makes it possible to reduce the number of company equipment and the related operating costs by constantly adapting the agent to the various work requirements. Accordingly, the device to be cleaned will include a single support structure that will operate as a power unit and various work devices to be connected in accordance with the various requirements.
  • the device according to the invention enables the question to be completely solved by using a single work program which can be equipped with various devices depending on the corresponding work requirements.
  • a self-propelled cart is provided, which is controlled by the operator standing on the ground by means of a handlebar provided with a power unit.
  • the various types of work devices can only be attached in joints to assemble machines to meet different requirements.
  • the transmission of motion from the self-propelled vehicle to the attached device is provided by a hydraulic means with a chain, drive belt or other accessories.
  • the power unit as well as the attached devices are driven by one or more hydraulic distributors attached to the steering device.
  • the agent moves on the attached front pair of wheels.
  • the machine is parked on three armrests mounted on the frame, which are carried by the frame and brought into working position by tipping over.
  • the floor parking of this running board allows access to the base of the car that holds the motor and the container.
  • Picture 1 is the side view a self-propelled wagon according to the invention including a power unit and with an attached excavator arm.
  • Figure 2 is a schematic view of the attachment system for the excavator arm of the truck.
  • the embodiment shown uses the handlebar 1, which is attached to the middle arm 2 in a unique manner, namely between the vertical tubes 3, which together with the base 4 complete the car frame.
  • Said pad 4 carries the oil tank 5 and the diesel engine 6 mounted thereon.
  • the support pad 4 shows a running board 8 which is mounted on the pin 8 and allows the power unit to be reached. From the elevated non-working position, which allows the carriage adjustment, the foot board 8 is brought down by tipping over by means of the piston, which is located below the base 4, in order to form a central rear storage plate of the machine.
  • the shutdown is completed with the front pair of feet 10, which is brought into a non-contact position by tilting upwards onto a pair of tooth storage stars 13 each.
  • the movement of the self-propelled car is made possible by the shaft 11 and the wheel set 12.
  • the two tabs 14 are involved, which support the pair of tabs 15, which are blocked by means of two pivot pins 16.
  • the two tabs 14 carry out the coupling of the device 17 with an excavator arm.
  • the two pins 16 are removed, the device 15 is pulled out and replaced with the other device in question, whereupon the movement and control transmission must be repaired again.
  • the embodiment provides a system for the transmission of motion, which is carried out by a hydraulic pump 18 which is switched on at the container 5 and is driven by the motor 6. This pump actuates the motor 19 connected to the reduction gear 20 and thus also the pin 11.
  • the control of all movements, both of the power unit and of the working devices which can be attached individually to the self-propelled vehicle NEN is provided by means of one or more distributors 21 which are constructed on the support arm 2 of the car steering rod.
  • the shape of the self-propelled wagon, that of the individual work and control devices, that of the joint and movement transmission means can be provided in different ways.
