Abstract

The invention discloses a screen safety protection device and method of a movable-type concrete jetting manipulator. The screen safety protection device comprises a man-machine interaction unit, a screen opening detection device unit, a control unit and a signal output unit. According to the screen safety protection device, on the basis of an output signal of an approaching switch sensor, the perpendicular distance between the signal face of the approaching switch sensor and an approaching switch induction plate is judged, so that the opening / closing state of a screen is judged, and a corresponding screen safety protection control signal is output by combining a control instruction of the man-machine interaction unit; and meanwhile the state of the signal is displayed in a display screen, and under the situation that the screen safety protection device meets operating of various working conditions is ensured, guarantee is provided for personal safety.

Description

technical field [0001] The invention relates to a mobile concrete spraying manipulator screen safety protection device and method, in particular to an effective device for detecting the closing / opening state of the screen, which outputs The corresponding screen safety protection control signal provides protection for personal safety while ensuring that the equipment meets various working conditions. Background technique [0002] When the mobile concrete spraying manipulator is spraying, the mixing device and concrete conveying device in the hopper are moving. If the screen of the concrete hopper is open, there will be a great potential safety hazard. [0003] In the prior art, an auxiliary mechanism is generally installed on the screen, and a limit switch is used in conjunction with it. When the screen is opened, the auxiliary mechanism will touch the limit switch, and the limit switch will send a signal, thereby obtaining the state of the screen and controlling the concrete...
