Concrete pumping equipment and motion control system and method of tail end hose thereof

Abstract

A movement control system for an end hose (20), comprising the end hose (20) arranged on a boom end section (335). The movement control system also comprises an operating handle (10), a boom posture monitoring unit (41), a movement control unit (42), and a movement actuator unit (43). The operating handle is arranged on the end hose. The operating handle is provided thereon with a direction control switch. The direction control switch allows an operator at the end hose to issue, on the basis of on-site casting conditions, a movement control command signal for moving the end hose in a direction as desired, and to control the movement of the boom end in conjunction with a boom-end current position signal generated by the boom posture monitoring unit, thus increasing the movement precision of the end hose, construction efficiency, and construction safety for the operator. Correspondingly, also provided are a movement control method for the end hose and a concrete pumper apparatus.

Description

technical field [0001] The invention relates to concrete pumping equipment, in particular to a motion control system and method for the concrete pumping equipment and its end hose. Background technique [0002] Concrete pumping equipment is a machine that uses pressure to continuously transport concrete along pipelines. It is widely used in various fields such as road engineering, bridge engineering, underground engineering, industrial and civil construction. Concrete pump truck is a typical concrete pumping equipment. [0003] The boom of the concrete pump truck is generally composed of at least three boom sections, each boom section is hinged by a hinge shaft, and each boom section can rotate a considerable angle around the hinge shaft. On the one hand, the whole arm frame can be driven by the hydraulic motor to rotate 360° around the vertical axis perpendicular to the horizontal plane under the drive of the turntable. The conveying pipe of the concrete pump truck is att...

Problems solved by technology

[0004] At present, in terms of the movement control of the hose at the end of the concrete pump truck, the operator of the pump truck can only rely on the operator of the pump truck to control the expansion and contraction of each boom cylinder through the wireless remote control or the controller in the electric control cabinet of the pump truck to realize the end of the boom (end However, the operator of the pump truck and the operator of the end hose are not the same person, and the operator of the remote control is generally far away from the pouring position. In many cases, the operator of the pump truck is not Knowing the specific construction trajectory intention of the operator at the end of the hose, the communication between them is not smooth, resulting in reduced construction efficiency, and even brings safety hazards to the operator at the end of the hose
