Title:
コンクリートポンプ用分配弁、コンクリートポンプ及びその制御方法、並びにコンクリートポンプ車
Document Type and Number:
Japanese Patent JP2013519026
Kind Code:
A
Abstract:
A distribution valve for a concrete pump, the concrete pump, a control method thereof and a concrete pump truck are provided. In which, the distribution valve comprises a valve body (200) and a wear resistance plate (300). The valve body (200) comprises a first suction pipe (210) and a first pumping pipe (220), the rear end of the first suction pipe (210) is communicated with an outlet (401) of a material container (400) so as to communicate the material container (400) and a conveying cylinder. The rear end of the first pumping pipe (220) is rotatablely connected with a delivery line of the concrete pump so as to communicate the conveying cylinder and the delivery line. The valve body (200) can be switched between a first state and a secondary state under the driving of a drive mechanism (500). In the first state, concrete slurry is sucked into the conveying cylinder through the first suction pipe (210), and in the secondary state, the conveying cylinder pumps the concrete slurry through the first pumping pipe (220). Because of the distribution valve, the concrete pump can thoroughly employ the self-flowing characteristic of concrete slurry in order to increase the suction performance of the concrete pump. In the meanwhile, because the distribution valve has higher pressure enduring capacity, the concrete pump can make concrete slurry have higher pressure via the conveying cylinder, thereby meeting the requirements of high-pressure pumping of concrete slurry.
