Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the drawings:

[0024] Such as figure 1 As shown, in the method of the present invention, when the controller 6 detects the closing signal of the unfolding button 11, it indicates that the driver wants to perform the operation of unfolding the stairs. The controller 6 detects the status of the safety handle switch 5, if the safety handle switch 5 is closed, it means that the super-large excavator is not working at this time, and the stairs are allowed to expand, otherwise it is not allowed. The controller 6 detects the status of the retracting proximity switch 1 and the locking proximity switch 4, if the retracting proximity switch 1 and the locking proximity switch 4 are closed, it indicates that the stairs are in a retracted state and the stairs can be unlocked. The controller 6 drives the unlock solenoid valve 7 to unlock the stairs, and at the same time detects the state of the unlock ...

Abstract

The invention discloses a method for controlling an ultra-large type excavator stairway and relates to the technical field of ultra-large type excavators. According to a controller, the real-time state of the stairway is detected through a proximity switch, and whether the stairway needs to be unfolded or folded is judged according to button operation. Meanwhile, the on-off state of a safety handle is detected, and when the safety handle is closed, unfolding and folding of the stairway is carried out. The method is suitable for controlling the ultra-large type excavator stairway, it is guaranteed that when the ultra-large type excavator carries out operation, the stairway is in a folded state, and the loss caused by stairway damage is avoided.

Description

Technical field [0001] The invention relates to a method suitable for stair control of a super-large excavator, belonging to the technical field of super-large excavators. Background technique [0002] Super-large excavators are mainly used in large-scale mines. They are characterized by large dimensions and require stairs to enter the excavator for operation or maintenance. The unfolding and retracting of the stairs is realized by manual operation of two buttons. When the super large excavator is working, the stairs must be retracted, otherwise the stairs will be damaged when turning. It often happens that drivers forget to retract the stairs and operate the super-large excavator, which damages the stairs and causes relatively large economic losses. Summary of the invention [0003] The purpose of the present invention is to provide a method suitable for the control of the stairs of a super-large excavator, which ensures that the stairs are in a retracted state when the super-l...
