Abstract

The invention relates to a concrete pump truck body frame and a concrete pump truck. The concrete pump truck body frame comprises a first supporting part, a second supporting part and a rotary supporting base. Before the body frame is formed, the rotary supporting base, the first supporting part and the second supporting part are independent components; the body frame is configured to be formed bywelding the first supporting part, the second supporting part and the rotary supporting base; and the first supporting part and the second supporting part are welded to form an X shape. The concretepump truck body frame is divided into the first supporting part, the second supporting part and the rotary supporting base, all sub-components are integrally tailor-welded after being tailor-welded, and each sub-component is relatively simple in structure, regular in weld joint and easy to independently perform automatic welding; the number of connecting weld joints between the sub-components is small, the connecting weld joints are all external weld joints, continuous and tidy, and parallel manufacturing can be achieved; and point splicing and pairing are conducted for overall automatic welding after construction is completed, so that automatic welding is easy, the welding production efficiency and the welding quality are improved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a concrete pump truck underframe and a concrete pump truck. Background technique [0002] Concrete pump truck is a kind of construction machinery that transports commercial concrete to designated locations. The concrete pump truck includes an underframe and outriggers, and the underframe connects the slewing bearing and outriggers; the outriggers are used to support the whole vehicle when the concrete pump truck is working. [0003] The related concrete pump truck adopts X-shaped outriggers, and the corresponding underframe is X-shaped. The X-shaped underframe is generally a single-piece structure, which is welded as a whole, has a complex structure, and has many internal welds. It is difficult to perform automatic welding, and the automatic welding rate Therefore, the X-shaped underframe has always been a structural part of concrete pump trucks with poor workmanship and dif...
