Problems solved by technology
However, the working mechanisms of different types and models of rotary machines have different sizes of rotational inertia. Therefore, the installation positions of the above-mentioned first detection switch 13 and second detection switch 14 are not easy to control, resulting in a poor effect of limiting the working area of the rotary machine.
[0008] To sum up, how to solve the problem of poor operation area restriction effect of rotary machinery has become a technical problem to be solved urgently by those skilled in the art

The invention discloses an operation area limiting method used for limiting the rotating direction of a working mechanism of a rotary machine. The method comprises the steps: (S11) detecting whether the rotary machine is in a unilateral operation state, and entering the step S12 if the rotary machine is in the unilateral operation state; (S12) confirming the target operation area of the working mechanism, receiving target operation signals, and acquiring the current position of the working mechanism; (S13) when the current position is located in the target operation area, executing target operation signals, when the current position is located on the boundary of the target operation area and the executing target operation signals enable the moving tendency of the working mechanism to be keeping close to the target operation area, executing the target operation signals, and when the current position is located on the boundary of the target operation area and the executing operation target operation signals enable the moving tendency of the working mechanism to be keeping far away from the target operation area, forbidding to execute the target operation signals. The method can improve operation area limiting effect. The invention further discloses an operation area limiting device and a fire fighting truck.
Description
technical field [0001] The invention relates to the technical field of rotary machinery, in particular to a method for limiting an operating area. The invention also relates to a working area limiting device and a fire truck. Background technique [0002] Swing machines such as fire trucks and cranes generally include a chassis, a turntable, and a working mechanism mounted on the turntable. The working mechanism rotates relative to the chassis through the turntable to achieve a full 360° rotation. In order to increase the stability of the rotary machine during work, the entire car body is supported on the ground by horizontal outriggers and vertical outriggers, thereby increasing the support span of the car body to achieve the above purpose. [0003] However, when the above-mentioned rotary machine is working, if its working area is relatively narrow, only one side of the supporting legs on both sides can be stretched out. At this time, if the working mechanism rotates to ...
