Conveying pipeline, boom system and operating equipment

Abstract

The invention discloses a boom system which comprises a boom and a conveying pipeline. The boom comprises a first arm, a middle arm and a tail arm which are hinged sequentially, the conveying pipeline comprises a first pipeline body, a middle pipeline body and a tail pipeline body which are fixedly arranged on the first arm, the middle arm and the tail arm respectively and are connected sequentially, the middle pipeline body comprises a first pipeline, a second pipeline and a pipeline switching device, an inlet of the first pipeline is communicated with the first pipeline body, an outlet of the second pipeline is communicated with the tail pipeline body, and the pipeline switching device is used for disconnecting or connecting the first pipeline with the second pipeline. The boom system is provided with two discharging ports used for long-distance distribution and short-distance distribution respectively, and harm caused by 'bypassing' of concrete in the conveying pipeline during short-distance distribution can be avoided. Additionally, the invention further discloses the conveying pipeline and operating equipment provided with the boom system.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a conveying pipeline, and also relates to a boom system and operating equipment with the boom system. Background technique [0002] At present, operating equipment with boom systems are more and more widely used in engineering operations, such as concrete pump trucks, placing booms, fire trucks with booms, etc., which bring great convenience to operations or construction. The boom system usually includes a boom and a conveying pipe on the boom. The boom includes a plurality of sequentially articulated first booms, intermediate booms (multiple intermediate booms are generally set according to actual needs) and a last boom; Correspondingly, the conveying pipe includes the first pipe, the intermediate pipe corresponding to the intermediate arm (corresponding to multiple intermediate arms, multiple intermediate pipes can be set) and the last pipe; the first pipe is installed on ...
