Embodiment Construction

[0025] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0026] like figure 1 As shown, the concrete pump truck is represented by reference numeral 10 and mainly includes a vehicle chassis 11 with a cab 12 and a vehicle frame 13 , and the boom 15 is mounted on the vehicle frame 13 through a turntable 16 . figure 1 The boom 15 shown in has seven boom sections 21-27 in total, starting from the turntable 16, followed by the first boom section 21, the second boom section 22, the third boom section 23, and the fourth boom section 24. The fifth boom section 25, the sixth boom section 26 and the seventh boom section 27 are hinged to each other between adjacent boom sections. The jib 15 rotates around the turntable 16 along...

Abstract

The invention provides an arm support of a concrete pump truck. The arm support has a folding state and an unfolding state and comprises at least six arm sections which are sequentially hinged with one another, wherein in the folding state, a first arm section and a second arm section are positioned on a first longitudinal surface; a fourth arm section, a fifth arm section and a sixth arm sectionare positioned on a second longitudinal surface; the first longitudinal surface and the second longitudinal surface are mutually parallel and are separated from each other; a third arm section is extended between the first longitudinal surface and the second longitudinal surface; the first, second, third, fourth and fifth section arms are folded towards a first direction; and the sixth arm section is folded to the fifth arm section towards a second direction opposite to the first direction. The invention also provides the concrete pump truck with the arm support. According to the technical scheme, the conveying distance of concrete can be increased as far as possible when the arm support is unfolded under the condition that the integral size of the pump truck in the folding state is not increased basically.

Description

technical field [0001] The present invention relates to concrete or other construction material conveying equipment, in particular to a concrete pump truck boom and a concrete pump truck including the boom. Background technique [0002] Concrete delivery pump truck (also referred to as "concrete pump truck" or "pump truck") is to install the concrete pump and folding boom on the chassis of the car, and lay concrete delivery pipelines along the boom, and finally output through the end hose Concrete conveying machinery. The folding boom has a folded state and an unfolded state. In the folded state, the boom is folded and put on the chassis so that the pump truck can drive on the road. In the unfolded state, the jib is extended to pour concrete from a distance. [0003] Knownly, the folding forms of the jib mainly include R-shape, Z-shape and RZ-shape. The R-shaped folding means that the multi-section boom section is folded in one direction, such as clockwise, and unfolded ...
