The turntable 401 is further provided with a column 404, one end of the tension spring 70 is connected with the column 404, the other end of the tension spring is connected with the far end of the stop part 50, when the rotation speed of the turntable 401 is reduced or stops rotating, the centrifugal force is weakened, the centrifugal force applied to the stop part 50 is smaller than the pulling force of the tension spring 70 on the stop part 50, and the stop part 50 is separated from the limiting opening 1010 and reset in the process of reversing along with the turntable 401, so that the turntable 401 can continue to rotate by utilizing the tightening force of the coil spring 60 until the balance is kept and the rotation is stopped.
In one example, when the emergency anti-pulling protection device is used in a cleaning robot, the safety rope 20 should be tied to the cleaning robot and the vacuum chuck is pressed and adsorbed onto a safe plane, after the cleaning robot is separated from a working surface during operation, the safety rope 20 tied to the cleaning robot is stretched to reduce the length wound on the rotating shaft 40, since the rotating shaft 40 is pulled by the weight of the cleaning robot to rotate rapidly during the falling process, the rotating speed of the rotating shaft 40 due to the pulling of the safety rope 20 is faster as the weight of the cleaning robot is larger, a strong centrifugal force is generated during the rotation of the rotating shaft 40 by the rotating disc 401 of the rotating shaft 40, the free distal end of the stopper 50 is thrown outwards by the centrifugal force, and the distal end of the stopper 50 is inserted into the limiting opening 1010 after being thrown, so as to prevent the rotating shaft 40 from continuing to rotate, and further prevent the safety rope 20 from being stretched, finally, the cleaning robot is pulled, and the cleaning robot is prevented from continuously falling. After the cleaning robot cancels the pulling force on the safety rope 20, the rotating shaft 40 rotates under the action of the coil spring 60, the distal end of the stopping part 50 is separated from the limiting opening 1010, and the safety rope 20 is pulled by the rotating shaft 40 in the rotating process and is gradually wound on the rotating shaft 40.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
