Automatic inclination correcting method and device

Abstract

The invention relates to an automatic inclination correcting method and device. The method includes the flow of correcting the angle of declination of an underground working device around an x axis or a y axis, and the flow specifically includes the steps that an inclinator is used for detecting the angle of declination of the underground working device around the x axis or the y axis and sending the detected value of the dip angle to a controller; the controller judges whether the value of the dip angle reaches a preset threshold value or not, and if the value of the dip angle reaches the preset threshold value, part of inclination correcting mechanisms to be driven and an inclination correcting angle value are determined according to a coordinate axis on which the value of the dip angle is based and the sign of the value of the dip angle; the controller sends control signals to electromagnetic directional valves corresponding to part of the inclination correcting mechanisms to be driven to drive part of the inclination correcting mechanisms to be driven to move till the inclination correcting angle value is reached. The multiple inclination correcting mechanisms on the underground working device can automatically and properly conduct inclination correcting based on inclination of the underground working device, high inclination correcting accuracy can be achieved without depending on the experience and the state of an operator, and grooving quality is improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an automatic deviation correction method and device for an underground working device of foundation pile engineering machinery. Background technique [0002] The double-wheel slot milling machine is a kind of construction machinery equipment for large-depth slotting by suspending the milling cutter frame by a steel wire rope. It is mainly used in construction of water conservancy projects and other constructions. During the construction process, the deviation of the working posture of the milling cutter holder relative to the initial state affects the construction quality, the smaller the deviation, the better the groove quality. With the vigorous development of water conservancy projects in my country, the application of double-wheel slot milling machines will increase, and the requirements for deviation correction control of milling cutter holders will also become higher an...

Problems solved by technology

[0005] Obviously, neither the manual control correction method nor the semi-automatic control correction method can timely and accurately control the milling tool holder of the double-wheel slot milling machine, which will not only consume too much energy of the operator, but also lead to low work efficiency. Moreover, the deviation correction accuracy cannot be guaranteed. The deviation correction accuracy depends to a large extent on the operator's experience and state. Insufficient deviation correction accuracy will also make it difficult to maintain the working track of the milling cutter holder on the construction center line, resulting in poor groove quality.
