A pump truck and its boom system

Abstract

The invention discloses a pump truck boom system. The pump truck boom system comprises a boom, a tail end delivery pipe and an extension boom which is detachably connected with the boom, a delivery pipe is arranged beside the boom, an extension delivery pipe is arranged beside the extension boom, the delivery pipe is detachably connected with the extension delivery pipe, and the tail end delivery pipe is respectively and detachably connected with the delivery pipe and the extension delivery pipe. When a pump truck is used for arranging materials, the tail end delivery pipe is delivery connected with the delivery pipe, the concrete in a conveying pipe is delivered to a material arranging site through the extension of the boom, and the tail end delivery pipe is used for arranging the materials. When the pump truck boom is not long enough to arrange the materials in some sites, the tail end delivery pipe is detached from the delivery pipe, the extension boom is connected with the boom, the extension delivery pipe is connected with the delivery pipe, and the tail end delivery pipe is connected with the delivery pipe, so that the boom can be extended temporarily, and the material arranging range can be expanded. The invention also discloses a pump truck with the pump truck boom system.

Description

technical field [0001] The invention relates to the technical field of concrete pump trucks, in particular to a pump truck and a boom system of the pump truck. Background technique [0002] Concrete pump truck, also known as pump truck, is a machine that uses pressure to continuously transport concrete along the pipeline. It is mainly composed of a pump body and a delivery pipe, which can transmit the power of the engine to the pump body. The delivery pipe is attached to the boom. The extension of the boom will transport the concrete in the delivery pipe to a certain height and distance for distribution. [0003] Each type of pump truck is limited by the industry standard, and the length of the boom is limited. When the concrete pump truck is distributing, because the distributing range is limited by the length of the boom, it is often encountered that the distributing material does not reach the point. At this time, it is necessary to replace the long-arm concrete pump tru...
