Definitions

• Fine-grained vehicle lateral movement device Fine-grained vehicle lateral movement device
• the present invention relates to a device for laterally moving a crane car such as a truck crane.
• Recent crane trucks especially truck crane, have a problem moving on narrow construction sites along with the trend of larger size.
• it is conventionally stored in a stretchable box circle on the body frame of the truck crane 10 so that it can be extended.
• the other is extended.
• the other side be contracted so that the truck crane can be moved / moved in the yellow direction.
• the lower surface of the inner side of the trigger beam in the vehicle width direction and the upper surface on the circular side of the outer side end of the trigger box in the vehicle width direction Are in contact with the lower side of the box and the upper side of the beam, respectively, and a load of truck crane 0 is applied to these contact parts.
• the sliding frictional resistance between the gear and the pet beam is considerably large.
• the present invention expands and contracts left and right in an outrigger box disposed on a vehicle body frame so as to extend in the vehicle width direction, and furthermore, An outrigger having a pair of trigger beams provided in close proximity to
• a second porter that can be applied to the upper surface of the above-mentioned trigger beam is attached to the above-mentioned trigger box.
• the above body near the upper end of the vehicle width direction is attached to the above-mentioned trigger box.
• the sliding friction resistance between the arpeggio beam and the arpeggio box is greatly reduced, the lateral movement is smooth, and the outgoing motion is reduced.
• the size of the rigging cylinder can be reduced.
• FIG. 3 is a schematic rear view of a track train showing a second embodiment of the lateral movement device according to the present invention
• FIG. 3 is an enlarged sectional view showing a main part of FIG. ,
• Fig. J (a back view showing the state in which the left trigger beam is extended,

• a pair of axle-extending cylinders that extend and retract so that they move in the same way as shown in the figure (only one cylinder combined with a beam is shown in the figure for simplicity of drawing). Is indicated)).
• the trigger beam and the trigger beam that extends to the right are arranged close to each other in the vehicle longitudinal direction.
• the above-mentioned trigger beam and ⁇ may be arranged so as to overlap or be close to each other in the vertical direction of the vehicle body.
• a lower part of an end of the left trigger beam in the vehicle width direction is attached to the lower part.
• the / roller // is pivotally supported via the rack f, and can roll on the lower inside surface of the outrigger box.
• Angle material or steel that is a vehicle-body-side strength member that extends to the side surface ⁇ of the vehicle J and is fixed to the upper part of the outer side end of the outrigger boxbar in the vehicle width direction.
• / ⁇ 2 is provided with bracket I.

• Fig. J (a) and (g) show the lateral movement of the truck crane, and Fig. J (a) shows the left-hand trigger beam.
• the outrigger beam corresponds to the rolling of the / rollano / and the J-roller I during the lateral movement of the truck crane. Slides on the trigger box via the arm, so that the sliding friction resistance between the beam and the box is greatly reduced, and the track clearance is reduced. Is it possible for the robot to move in the horizontal direction smoothly, and at the same time, to move in the horizontal direction using a small art. Rig extension cylinder? It can reduce the weight and cost of the trigger.

• the slope / is provided! ), As shown in the figure, when the truck crane moves in the horizontal direction, the rollers / / and / s roller support-/ and / It is easy to get on and off, and it does not obstruct the directional movement.
• the second practice of the present invention is that the mouthpieces // and / are always in contact with the trigger box and the trigger beam.
• the number 20 is such that contact can be made only when the outrigger beam is extended or retracted.
• the aforesaid trigger beam and the front trigger also have the same structure of the rollers, arms and oil cylinders as described above. Are provided.
• the oil ⁇ to gas overhanging and for sheet re down da 7 is supplied to the oil supply times - circuit whether et oil ⁇ that high-speed steel sheet, extending in the arrow direction of FIG. 7, b over La / /, the I Contact the trigger box and the outrigger beam
• the beam can be smoothly slid with respect to the box.
• the oil ⁇ cylinder ⁇ 2 /, 2 ejects oil and contracts, and the rollers / /,
