Claims

[Scope of utility model registration request]

An outrigger connection frame, which is provided with outriggers at both ends and extends in the left-right direction, is supported at the front and rear of the rock-cutting truck so that it can be moved laterally with respect to the truck and swingable within a substantially horizontal plane, and each outrigger connection frame is A pair of front and rear lateral movement cylinders that extend along the frame and have one end supported by the outrigger and the other end connected to the truck move the truck laterally when the outrigger touches the ground, and the difference in the amount of movement of these cylinders In a positioning device for a cart for rock drilling, which is configured to swing the cart by the above, the pair of lateral movement cylinders are each housed inside an outrigger connection frame, and the other end is pin-connected to the cart via a substantially vertical pin. Also, a swinging guide member is provided on the bogie, and an arcuate contact surface that allows the swinging of the outrigger connection frame contacts one front and rear side of the frame; a pair of pressing members supported movably in the longitudinal direction of the trolley so as to abut the other surface of the frame from the opposite side of the guide member; and a coil spring ′ that biases these pressing members toward the frame, respectively. A positioning device for a cart for drilling Iwatsuki, which is characterized by being provided with.
