Definitions

  • the invention relates to devices of the type of jib cranes with articulated or telescopic arms allowing the lifting or handling of loads with the grapple, the hook winch or the hook. It relates more particularly to a device ensuring the automatic balancing of the boom of such cranes as a function of the variation in the range of this boom.
  • the crane boom is generally articulated on the turret, without balancing, the counterweight being itself fixed on the turret.
  • the counterweight in fact only serves to reduce the overturning moment but by a fixed value and without compensation depending on the range of the boom.
  • the lifting cylinders of the main arm or the auxiliary arm must ensure both the lifting of the load, the boom and the load gripper.
  • the object of the invention is to avoid the above-mentioned drawbacks of known devices and, for this purpose, it proposes to equip the crane jib with a device ensuring automatically the balancing of this jib as a function of the variation. of its reach.
  • the value of the counterweight being calculated as a function of the dead weight of the elements of the boom (including the gripping means such as grapple or muffle which it supports) and according to the lever arms, the synchronized movements of the auxiliary arm and the counterweight (by supplying the control cylinder of one of them by means of the hydraulic fluid discharged from the control cylinder of the other) thus make it possible to obtain a choice of total or partial balancing of the boom.
  • the device according to the invention also makes it possible to considerably reduce the powers of the motor and receiver organs necessary for the movements of the load, and therefore to reduce energy consumption.
  • a hydraulic distributor in a first position, ensures the supply of hydraulic fluid to the chamber of the counterweight control cylinder which is not connected to the control cylinder of the auxiliary arm while the chamber of the control cylinder of the auxiliary arm which is not connected to the counterweight control cylinder is in communication with a fluid reservoir, the other chamber of the counterweight control cylinder transferring the hydraulic fluid to the other chamber of the auxiliary arm control cylinder.
  • This distributor in a second position, supplies fluid to the chamber of the control cylinder of the auxiliary arm which is not connected to the control cylinder of the counterweight and puts in communication with the fluid tank the chamber of the control cylinder of the counterweight not connected to the control cylinder of the auxiliary arm, while the chamber of the control cylinder of the auxiliary arm which is connected to the chamber of the control cylinder of the counterweight transmits the hydraulic fluid to this chamber.
  • the balancing device according to the invention can be applied to arrows with articulated arms as well as to arrows with telescopic arms.
  • FIG. 1 there is shown in 1 the crane base, in 2 the pivoting turret overhanging this base and in 3 the main boom arm hinged towards its rear end to the turret 2, around an axis horizontal 4, in order to be able to pivot in a vertical plane under the control of a hydraulic cylinder 5.
  • a hydraulic cylinder 5 At the front end of the main arm 3 is articulated, around a horizontal axis 6, an auxiliary arm 7 whose front end carries a gripping means constituted, in the example shown, by a grapple 8.
  • the angled rear end of the auxiliary arm 7 is integral with the free end of the rod 9 of a hydraulic cylinder 10 whose body is articulated on a yoke 11 secured to the main arm 3.
  • a balance 13 secured to a counterweight 14.
  • the balance 13 is articulated at one end of the rod 15 of a hydraulic cylinder 16, the body is pivotally attached to a yoke 17 carried by the main arm 3.
  • the operator then places the distributor 20 in the position corresponding to its right-hand part, looking at FIG. 1, so that the chamber 26 of the jack 16 is is supplied with pressurized fluid and, by displacement of the rod 15, simultaneously produces a tilting of the counterweight 14 and, due to the connection between the chambers 29 and 28 of the jacks 16 and 10, a lifting of the auxiliary arm 7.
  • the counterweight 14 is calculated as a function of the dead weight of the elements of the boom and of the grapple 8, and as a function of the lever arms, the boom is therefore permanently balanced (in whole or in part), on the assembly formed by the base 1 and the turret 2.
  • the distributor 20 is brought back to its intermediate position and the operations of lifting and lowering the load are then carried out by the jack 5.
  • the operator decides to reduce the reach of the boom, he will then have to place the distributor 20 in the position corresponding to its left part, looking at FIG. 1.
  • the chamber 24 of the jack 10 is then supplied, which produces the tilting of the auxiliary arm 7 and simultaneously, by the connection of the chamber 28 of this jack with the chamber 29 of the jack 16, which ensures the lifting of the counterweight 14 to ensure the automatic balancing.
  • FIG. 2 differs mainly from that of Figure 1 only in that the auxiliary arm 7 is mounted to slide telescopically inside the main arm 3, under the action of the hydraulic cylinder 10 '.
  • the grapple 8 in FIG. 1 has also been replaced by a system with winch 30 and block 31.
  • the hydraulic control device is practically the same as that in FIG. 1, except that the conduit 23 ′ connects the distributor. 20 to the annular section chamber 28 'of the jack 10', while the conduit 27 'connects in series the full section chamber 24' of the jack 10 'and the annular section chamber 29' of the jack 16 '.
  • the user will place the distributor 20 in its position corresponding to its right-hand part, looking at FIG.
