Turning angle detecting device for project vehicle turning table and project vehicle thereof

Abstract

The invention discloses a revolving angle detection device for revolving tables of construction vehicles, which comprises an angle measuring unit, a control unit and a zero-point inspection unit; wherein the angle measuring unit is used to measure the revolving angle of a revolving table and send the measurement to the control unit; the zero-point inspection unit defines the zero-point induction signal for the zero point of the rotation angle of the counter-rotating table, and send the signal to the control unit; the control unit is provided with a calibrating program in which a zero-point displacement is obtained according to the zero-point induction signal generated by the zero-point inspection unit and the numerical value captured by the angle measuring unit at that time; based on the zero-point displacement, the control unit converts an output magnitude from the angle measuring unit to be a coordinate angle magnitude taking the specific location of the revolving table as the zero point, and handles the control according to the angle magnitude. The revolving angle detection device has the advantage that very intuitive angle signals can be obtained, and is convenient for applications in occasions such as control against overturning.

Description

technical field [0001] The invention relates to a position detection technology of a turntable of an engineering vehicle, in particular to a detection device for a rotation angle of a turntable of an engineering vehicle. The present invention also provides an engineering vehicle using the above device. Background technique [0002] Various turntables are designed in many construction vehicles to provide slewing functions for actuators that require multi-directional operations. The most common actuator that requires slewing is the working arm. For example, construction vehicles such as construction cranes, concrete pump trucks, and fire trucks all have working arms that can be retracted or folded, and these working arms need to be rotated to realize the basic operation actions of these construction vehicles. For example, hoisting objects or people from one location to another, as well as concrete pouring operations, all-round lifting operations of cranes, etc. The way to r...

AI Technical Summary

Problems solved by technology

Under the existing technology, there is no comprehensive detection of the rotation angle of the turntable relative to the vehicle body, and no effective data support can be obtained when realizing functions such as anti-rollover of engineering vehicles
