Concrete pump vehicle supporting leg and concrete pump vehicle therewith

Abstract

The invention discloses a landing leg of a concrete pump truck; the supporting end of the basic arm of the landing leg is hinged on the body of the concrete pump truck by a rotating shaft arranged with an angle less than 45 degrees with a horizontal plane; when being folded from a supporting position, the landing leg rotates towards the inner side surrounding the rotating shaft; besides, when the landing leg finally reaches a folding position, the angle between the basic arm of the landing leg and the vertical line of the horizontal plane is less than 80 degrees. In the preferable scheme of the invention, the landing leg can adopt the forms of a single-section landing leg or a multi-section landing leg. The folding position of the landing leg is arranged above the body of the truck; and the landing leg can be arranged by utilizing the upper part space of the body of the truck by proper arrangement. When the landing leg moves from the folding position to the supporting position, the landing leg moves in a plane vertical to the horizontal plane and can not be baffled by a barrier on the horizontal plane; besides, the restriction to the concrete pump truck in a construction field comes from barriers on the horizontal plane; therefore, compared with the swing type landing leg of the prior art, the landing leg of the invention is more flexible for being unfolded. The invention simultaneously provides a concrete pump truck which uses the landing leg.

Description

technical field [0001] The invention relates to a support leg of a concrete pump truck, in particular to a concrete pump truck with the support leg. The present invention also provides a concrete pump truck with the above outrigger. Background technique [0002] Concrete pump trucks (Pump Truck / Truck-mounted concrete pump) need to use support devices to achieve support during work. cause overturn. The supporting device generally includes two pairs of outriggers at the front and back, and each outrigger has two positions of retracting and supporting. When the concrete pump truck is going to move, the outriggers need to be retracted for easy movement. In this position, the outriggers are in a retracted state; when the concrete pump truck is in construction, the outriggers need to be expanded to achieve support. In this position, the outriggers are in support state. The above two states can ensure that the outrigger can play a supporting role without affecting the movement ...
