Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0034] like figure 1 and figure 2 As shown, on the one hand, the present invention provides a method for leveling the bodywork of tower construction machinery, the bodywork includes a turntable 1 and an arm frame 2 installed on the turntable 1, wherein the leveling method includes: a detection step , real-time detection of the inclination angle of the bodywork; and a control step of judging whether the bodywork has reached a level state according to the detected inclination angle, and if the bodywork has reached a level state, then end leveling; if the bodywork has not reached a level state , then adjust the pitch angle θ of the jib 2 of the bodywork until th...

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 ...
