Definitions

  • the present invention relates to an outrigger extend-retract system that can extend and shorten in the telescopic boom and knuckle boom cranes.
  • the present invention particularly relates to an outrigger extend-retract system with compact structure capable of horizontally extending with three segments that enables the outriggers to be extended and retracted by means of a single piston by opening and closing telescopically in a synchronous manner.
  • the outriggers used in the present state of the art are generally opened and closed by extending and retracting the same in three stages on the horizontal axis. This extending and retracting movement is carried out by a mechanism with three hydraulic pistons placed in the outriggers. Moreover, since there is not enough space in outriggers, locating the mechanism that performs the extending and retracting process inside the outrigger during the assembly phase causes loss of time and high costs in production. Furthermore, due to the three-piston mechanism and the hydraulic lines of these pistons, a serious cost increase and extra weight in the crane structure is seen. Meanwhile, the hydraulic line and the cables of the electric line that influence the operation of the system must be connected to the outside of the outrigger since the mechanism occupies a lot of space in the outrigger.
  • the invention relates to a support boom for mobile work machines, particularly for mobile concrete pumps, having a push-out box disposed on a chassis, preferably so as to pivot, having a telescope part consisting of several telescope segments guided inside one another.
  • Present document has not outrigger extend-retract system with compact structure capable of horizontally extending with three segments that enables the outriggers to be extended and retracted by means of a single piston by opening and closing telescopically in a synchronous manner.
  • the present invention is related to an outrigger extend-retract system capable of horizontally extending with three segments which eliminates the abovementioned disadvantages and brings new advantages to the relevant technical field.
  • the main aim of the invention is to provide an outrigger extend-retract system with compact structure that enables the outriggers to be extended and shortened by means of a single piston.
  • the aim of the invention is to enable the outriggers to be opened and closed telescopically by means of a single piston in a synchronous manner.
  • Another aim of the invention is to reduce the total weight of the outrigger by opening and closing the outriggers by means of a single piston.
  • Another aim of the invention is to provide that the hydraulic line and the electric line are taken into the telescopic rail and move within the telescopic rail during the opening and closing of extend-retract system.
  • Another aim of the invention is to eliminate the use of external drums with the presence of the hydraulic line and the electric line within the telescopic rail.
  • Another aim of the invention is to eliminate the failure of the hydraulic line and the power line due to external factors, and in case of a possible breakdown, to prevent the occupational accidents and work losses due to breakdowns.
  • Another aim of the invention is to reduce the cost by eliminating the difficulties encountered during the assembly of extend-retract system to the outrigger.
  • extract-retract system mainly comprises the following; main sleeve rail (10) with a fixed structure, 1 st rail (11) that opens and closes by moving back and forth within the main sleeve rail (10), 2 nd rail (12) that opens and closes by moving back and forth within 1 st rail (11), 3 rd rail (13) that opens and closed by moving forward backward in the 2 nd rail (12), piston sleeve (20) with a fixed structure connected into the 2 nd rail (12), 1 st rod (30), which is engaged into the main sleeve rail (10) and opens and closes the 1 st rail (11) by entering into the piston sleeve (20), 2 nd rod (40), which is engaged into the 1 st rail (11) and opens and closes the 2 nd rail
  • the main sleeve rail (10), 1 st rail (11), 2 nd rail (12) and 3 rd rail (13), which constitute the main structure of the inventive extend-retract system, have a structure that gradually opens and closes in a telescopic manner in the horizontal axis.
  • Main sleeve rail (10) is fixed.
  • a fixed piston sleeve (20) is connected inside the 2 nd rail (12) to enable the opening and closing of the 1 st rail (11) and 2 nd rail (12).
  • 1 st rod (30) that opens and closes the 1 st rail (11) by opening and closing into the piston sleeve (20) is engaged into the main sleeve rail (10) and 2 nd rod (40) that opens and closes the 2 nd rod (12) by opening and closing into the piston sleeve (20) in engaged into the 1 st rail (11).
  • the opening and closing movement of the 3 rd rail (13) is provided by the extending chain or rope (50) that opens the 3 rd rail (13) by extending the same on the 2 nd pulley (120) connected to the 3rd rail (13) during the opening movement of the 2 nd rail (12) and by a retracting chain or rope (60) which closes the 3 rd rail (13) on the 1 st pulley (70) connected to the 2 nd rail (12), during the closing movement of the 2 nd rail (12).
  • the 1 st rod (30) is opened by means of the hydraulic line (80) inside the piston sleeve (20) to open extend-retract system, and it opens the 1 st row (11) by extending the same from the main sleeve rail (10). Then the 2nd rod (40) opens and opens the 2nd row (12) by pushing the same through the 1st rail (11). During the opening of the 2 nd rail (12), the extending chain or rope (50) on the 2 nd pulley (120) engaged to the 3 rd rail (13) opens the 3 rd rail (13) by extending the same. Thus, the extension of the outrigger (not shown in the figures) is ensured.
  • the 1 st rod (30) closes and closes the 1 st row (11) by retracting the same to the main sleeve rail (10). Then the 2nd rod (40) closes and the 2nd row (12) by retracting the same inside the 1st rail (11).
  • the retracting chain or rope (60) that is on the 1st pulley (70) engaged to the 2nd rail (12) closes the 3rd rail (13) by retracting the same into the 2nd rail (12).
