Control method and control device for controlling rotation of turnplate of pump truck and pump truck

Abstract

The invention discloses a control method and a control device for controlling rotation of a turnplate of a pump truck and the pump truck. The control device comprises the following steps: acquiring the current boom tail end amplitude; according to the current boom tail end amplitude and the maximum boom tail end linear velocity, acquiring the turnplate rotating maximum set angular velocity under the current tail end amplitude; according to the maximum set angular velocity, determining the relationship between the turnplate rotating angular velocity and the opening angle of an operating handle; according to the current opening angle of the operating handle and the determined relationship between the turnplate rotating angular velocity and the opening angle of the operating handle, controlling the turnplate to rotate at the corresponding angular velocity. By the control device, the maximum turnplate rotating set angular velocity can be dynamically controlled according to the boom tail end amplitude, and the control rapidness of a boom of the pump truck is improved on the basis that the safety of users and equipment is ensured.

Description

technical field [0001] The present disclosure relates to the field of pump trucks, and in particular, to a control method, a control device, and a pump truck for rotating a turntable of a pump truck. Background technique [0002] The pump truck achieves the purpose of material distribution through the movement of the multi-section boom. At present, the pump truck controls the rotation of the turntable and the angular speed of the rotation through the operating handle. When the opening angle of the operating handle is the largest, the angular speed of the turntable rotation is the largest and is a fixed value. , the turntable drives the movement of the boom so as to achieve the purpose of distributing materials in different ranges. However, in order to ensure the safety of users and equipment, the linear velocity at the end of the boom will be limited within the standard range, so the maximum angular velocity of the turntable rotation will also be limited to the linear veloci...

Problems solved by technology

However, in order to ensure the safety of users and equipment, the linear velocity at the end of the boom will be limited within the standard range, so the maximum angular velocity of the turntable rotation will also be limited to the linear velocity range when the boom amplitude is the largest, but this is to a certain extent It affects the rapidity of the operation of the boom of the pump truck
