Abstract

The invention discloses an upper assembly leveling method of tower type engineering machinery. An upper assembly comprises a rotating table (1) and an arm frame (2) mounted on the rotating table (1), and the leveling method comprises the following steps: the detection step: detecting the inclination angle of the upper assembly in a real-time manner; the control step: judging whether the upper assembly achieves the horizontal state or not according to the detected inclination angle, if the upper assembly achieves the horizontal state, finishing leveling; and if the upper assembly does not achieve the horizontal state, regulating the pitch angle (theta) of the arm frame (2) of the upper assembly till the upper assembly achieves the horizontal state. The invention further provides a corresponding upper assembly leveling device of the tower type engineering machine. According to the technical scheme, the pitch angle of the arm frame can be automatically regulated according to the detected inclination angle of the upper assembly till the upper assembly achieves the horizontal state without manual operation, so that the efficiency is high, the safety is high and the leveling precision can be ensured.

Description

technical field

[0001] The invention relates to the field of engineering machinery, in particular to a method and device for leveling the top of a tower construction machinery. Background technique

[0002] Tower construction machinery is a widely used construction machinery. like figure 1 As shown, the tower construction machine may include a tower body 7 arranged on the base foundation 6 and a bodywork arranged on the tower body 7 . The tower body 7 is mainly constructed by a plurality of standard sections 8 . The bodywork may include a turntable 1 arranged on the top of the tower body 7 and a jib 2 , a balance arm 10 , a control room 11 and the like arranged on the turntable 1 . The tower body 7 of the tower construction machinery can add or reduce the number of standard sections 8 through its own climbing and jacking device 9, so as to meet the requirements of different building heights. When increasing or decreasing the standard section, it is necessary to keep the ...
