[0002] In the current pump trucks, when the sliding leg slides relative to the turret side plate, the position of the limit member on the sliding leg and the turret side plate is fixed. Therefore, the relative position between the sliding leg and the turret side plate is fixed during the limiting process. This fixes the length of the sliding leg extending out of the turret side plate, which cannot be applied to different working conditions. Based on this, a limit component is designed, and under the action of the limit component, the length of the sliding leg extending out of the turret side plate can be adjusted at will, which is a technical problem that needs to be solved urgently. Utility Model Content

[0007] The limiting assembly provided by the utility model comprises a leg stopper, a turret stopper and an adjusting assembly, wherein the leg stopper is arranged on the sliding leg; the turret stopper is arranged on the turret side plate and is located on a side close to the leg stopper, and when the leg stopper follows the sliding leg to slide, the turret stopper can limit the leg stopper, thereby limiting the length of the sliding leg extending out of the turret side plate; the adjusting assembly is connected to the turret stopper or the leg stopper, and the position of the leg stopper on the sliding leg or the position of the turret stopper on the turret side plate can be adjusted along the sliding direction of the sliding leg. Since the position of the turret stopper or the leg stopper is adjustable along the sliding direction of the sliding leg, when the sliding leg is limited by the turret stopper and the leg stopper, it is equivalent to adjusting the length of the sliding leg extending out of the turret side plate, and thus it can be suitable for different working conditions.
