Embodiment Construction

[0044] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0045] figure 1 It is a flowchart of a method for determining the load of a working platform of an aerial work machine provided by an embodiment of the present invention. Such as figure 1 As shown, the aerial work machinery includes a flying arm connected to the working platform, and the method includes:

[0046] Step S11, detecting the state of the flying arm;

[0047] For example, the state of the fly arm may include a moving state and a non-moving state. The state of the fly arm can be obtained by detecting whether the fly arm valve is open. For example, when the fly arm va...

Abstract

The embodiment of the invention provides a method and device for determining load and overload of a high-altitude operation machine and the high-altitude operation machine, and belongs to the field of high-altitude operation machinery. The high-altitude operation machine comprises a fly jib connected with a working platform. The method for determining load comprises the steps that the state of the fly jib is detected; when the fly jib is in a non-motion state, the pressure of a rodless cavity of an oil cylinder of the fly jib and the angle of the fly jib are detected; and the load of the working platform is determined at least according to the pressure of the rodless cavity and the angle of the fly jig. The corresponding structure does not have the risk of colliding with the working platform, the structure is simple, and the structural weight of the working platform can be reduced.

Description

technical field [0001] The invention relates to the field of high-altitude working machinery, in particular to a method and device for determining the load and overload of high-altitude working machinery and high-altitude working machinery. Background technique [0002] As a man-carrying device, the working platform of aerial work machinery needs to specify the rated load capacity during design and manufacture. When the platform is overloaded, various emergencies are prone to occur, resulting in potential safety hazards. [0003] However, existing overload determination methods such as: [0004] 1. Through the cooperation of the spring, travel switch (or proximity switch) and the stopper, when the load of the working platform exceeds the limited weight, the spring deforms and compresses downward, driving the entire working platform to slide down along the support column with the slide rail, thereby driving The limit switch moves downward to touch the stopper, and an electr...
