Multi-row rope measuring device and method

[0044] A multi-row rope measuring device is provided in an embodiment of the present invention, comprising:

[0045] The pulse sensor is used to detect the number of pulses during the lifting or lowering process of the reel rotation;

[0046] The controller is connected with the pulse sensor, receives the pulse number sent by the pulse sensor, and calculates the sounding value based on the pulse number and a preset calculation strategy.

[0047] A display, the display is connected to the controller and used to display the sounding value sent by the controller and the length of the input wire rope.

[0048] In the specific implementation process, such as figure 1 As shown, the pulse sensor is connected to the main winding motor of the winch, and the main winding motor is connected to the reel to drive the reel to rotate; the reel is used to wind the winding rope.

[0049] In a specific implementation manner of an embodiment of the present invention, the step of calculating the s

[0060] A method for measuring multi-row ropes is provided in an embodiment of the present invention, including:

[0061] Use the pulse sensor to detect the number of pulses during the lifting or lowering process of the drum rotation;

[0062] Using the controller to receive the number of pulses sent by the pulse sensor, and calculate the sounding value based on the number of pulses and a preset calculation strategy;

[0063] A display connected to the controller is used to display the sounding value sent by the controller and the length of the input wire rope.

[0064] In a specific implementation manner of an embodiment of the present invention, the step of calculating the sounding value includes:

[0065] When the reel is arranged in multiple rows of ropes, and the reel is in the process of being lifted or lowered, the controller detects the pulse number P of the pulse sensor in real time s :

[0066] When P s ≤P n When , the sounding value D is calculated by the following
