Definitions

  • the present invention relates to a lateral moving apparatus for a crane car such as a truck crane.
  • a modern crane car, especially a truck crane has a problem of moving in a narrow site of construction, with the tendency of its oversizing.
  • a solution that one of a pair of right and left outrigger beams contained for telescopical movement in an outrigger box provided on the chassis frame of a truck crane is elongated and the other outrigger beam is contracted by elongating and contracting a pair of outrigger extruding cylinders at the same time, whereby the truck crane can be laterally moved.
  • the present invention proposes a lateral moving apparatus for a crane car having at least one or more outriggers which comprise a pair of outrigger beams provided for telescopical movement to the right and left and close to each other in an outrigger box arranged on a chassis frame so as to lie in the breadth direction of the car body, wherein extruding cylinders for said pair of outrigger beams are made capable of elongating and contracting at the same time so as to elongate one of the outrigger beams and contract the other outrigger beam, first rollers capable of contacting with the inner bottom surface of said outrigger box each are provided on the inside end of said outrigger beams in the breadth direction of the car body, and second rollers capable of contacting with the top surface of said outrigger beams each are provided on a strength member for the car body side which is near the outside upper ends of said outrigger box in the breadth direction, such as the chassis frame, the outrigger box or bracket.
  • the sliding friction resistance between the outrigger beams and the outrigger box can be reduced in a large extent, and as a result the lateral movement of the truck crane can be smoothly carried out and the outrigger extruding cylinders can be made small-sized.
  • the reference numeral 1 represents a rear outrigger provided behind the rear wheels 2, which is composed of an outrigger box 4 fixed on a chassis frame 3, a pair of right and left outrigger beams 5 and 6 contained for telescopical movement in said box 4, and a pair of outrigger extruding cylinders which are elongated and contracted so as to elongate and contract said beams 5 and 6 (In Fig. 1, there is shown only one cylinder 7 combined with the beam 5, for simplification of the drawings). Jacks 8 and 9 are fixed on the outside ends of the outrigger beams 5 and 6 in the breadth direction of the car body, respectively.
  • the outrigger beam 5 extensible to the left and the outrigger beam 6 extensible to the right are arranged close to each other in the longitudinal direction of the car body.
  • Said outrigger beams 5 and 6 may be arranged so as to be overlapped on each other or be close to each other in the vertical direction of the car body.
  • a first roller 11 is pivotally supported by way of a bracket 10 on the lower part of the inside end of the left outrigger beam 5 in the breadth direction of the car body and capable of rolling on the inner bottom surface of the outrigger box 4.
  • a bracket 13 is fixed on an angle bar or stay 12 which is a strength member for the car body side provided connectedly to the side of the chassis frame 3 and secured on the upper part of the outside end of the outrigger box 4 in the breadth direction of the car body, and a second roller 14 is pivotally supported on the bracket 13 close to said upper part of the outside end and capable of rolling on the top surface of the outrigger beam 5.
  • Said roller 14 may be attached by way of a bracket to the chassis frame 3, the outrigger box 4, the stay around the outrigger box or the like which constitutes the strength member for the car body side.
  • rollers 11 and 14 are provided in the same way as mentioned above.
  • a front outrigger with the same structure as the above-mentioned rear outrigger is fixed on the chassis frame 3 between the front wheels and the rear wheels 2.
  • Figs. 3 (a) and 3 (b) show the mode of the truck crane where it moves laterally
  • Fig. 3 (a) shows such a state that the left outrigger beam 5 is elongated and the right outrigger beam 6 is contracted.
  • the beam 6 is elongated and the beam 5 is contracted, whereby the truck crane is moved left to the position shown in Fig. 3 (b).
  • the designations L 1 and L 2 represent the distances between the center line of the car body of the truck crane and the outside end of the right outrigger beam 6, respectively
  • the difference L Z -L 1 means the moving distance of the truck crane.
  • the outrigger beams 5 and 6 are caused to slide with respect to the outrigger box 4 by utilization of the rolling of the first roller 11 and the second roller 14 in the lateral movement of the truck crane, and the sliding friction resistance between the outrigger beams and box can be reduced in a large extent and the lateral movement of the truck crane can be smoothly carried out. Accordingly, it enables to carry out the lateral movement of a truck crane by use of small-sized outrigger extruding cylinders, to reduce the weight of the outrigger and further to lower the cost.
  • roller supports 15 and 16 are provided on the inner bottom surface of the outrigger box 4 and the top surface of the outrigger beam 5 at the positions where they will confront the rollers 11 and 14 when the beam 5 is in the maximum elongated position, respectively.
  • Each of the roller supports 15 and 16 is made of a material with a large strength so as to form a reinforcing member, and has a touch face 17 with a curvature according with that of each roller 11, 14 and a sloping side 18 for facilitating each roller to get onto the roller support.
  • the area of the contact surfaces between the rollers 11, 14 and the outrigger box 4 and outrigger beams 5, 6 is increased by the touch face 17 of the roller supports.
  • the surface pressure of said contact surfaces onto which a load is being applied when the beams 5, 6 are elongated to the maximum limit in the crane working as shown in Fig. 4 can be therefore lowered, and this enables smaller rollers to be used. Since the sloping side 18 is provided on each of the roller supports 15, 16, furthermore, the rollers 11 and 14 can get easily onto the roller supports 15 and 16, without any obstruction to the lateral movement of the truck crane, when the truck crane is laterally moved as shown in Fig. 5.
  • the second embodiment of this invention shown in Fig. 6 and Fig. 7 is improved so that the rollers 11 and 14 can be brought into contact with the outrigger box 4 and outrigger beams 5 and 6 only when the outrigger beams are elongated and contracted, instead of their full-time contact.
  • a first roller 11 is pivotally supported on one end of a first arm 19 substantially shaped in the letter V, the center of said arm 19 is pivotally secured to the lower part of a bracket 10 by way of a pivot 20, and a hydraulic cylinder 21 which is a first pressure-responsive device is pivotally secured between the other end of the arm and the upper part of said bracket.
  • a second roller 14 is pivotally supported on one end of a second arm 22 substantially shaped in the letter V, the center of said arm 22 is pivotally secured to the lower part of a bracket 13 by way of a pivot 23, and a hydraulic cylinder 24 which is a second pressure responsive device is pivotally secured between the other end of the arm and the upper part of said bracket.
  • a hydraulic cylinder 24 which is a second pressure responsive device is pivotally secured between the other end of the arm and the upper part of said bracket.
  • the respective hydraulic cylinders 21, 24 are supplied with an oil pressure, for example, from an oil pressure supply circuit for feeding and discharging an oil pressure to or from the outrigger extruding cylinders 7 so as to be elongated in the direction of the arrow shown in Fig. 7, whereby the rollers 11, 14 can be brought into contact with the outrigger box 4 and outrigger beams 5, 6, and the sliding of these beams with respect to the box can be smoothly carried out.
  • the hydraulic cylinders 21, 24 are contracted by discharging the oil pressure therefrom, whereby the rollers 11, 14 are alienated from the outrigger box 4 and outrigger beams 5, 6, and the bottom surface of the inside end of the beams in the breadth direction of the car body and the inner top surface of the outside end of the outrigger box in the breadth direction are contacted with the inner bottom surface of the box and the top surface of the beams, respectively. Accordingly, the area of these contact surfaces can be more increased, with lowering the surface pressure.
  • this embodiment may be modified to such a structure that when the hydraulic cylinder 21, 24 are contracted, the load in the crane working is not applied to the rollers 11, 14, even if they are contacted with the outrigger box 4 and outrigger beams 5, 6.
  • FIG. 8 there is shown an oil pressure supply circuit for controlling the actuation of the outrigger extruding cylinders for the front and rear outriggers, wherein the reference numeral 7 represents a left and rear cylinder; 7' is a right and rear cylinder; 7" is a left and front cylinder; 7'" is a right and front cylinder; 25 is a tank; 26 is a pump; 27 to 27'" are solenoid-actuated control valves for controlling the feed and discharge of the oil pressure to said cylinders 7 to 7"' respectively.
  • Each control valve has an elongating position A, neutral position B, contracting position C and floating position D. At the floating position D, the oil pressure can be freely fed into or discharged from both the chambers of each cylinder.
  • the oil pressure supply circuit when shown in Fig. 8 provides the state where the front and rear outriggers stop at the position shown in Fig. 3 (b).
  • the lateral movement of the truck crane to the position shown in Fig. 3 (a) is carried out by bringing the control valves 27' and 27'" to the floating position D and the control valves 27 and 27" to the elongating position A.
