Example Embodiment

[0033] Example: braking force is 1200N, load is 1000N:

[0034] An implementation method of the above-mentioned towing winch with automatic tensioning function, the implementation method sequentially includes the following steps:

[0035] Step 1: Initially start the PLC control system 1 to read the data of the speed sensor 7. The data from the speed sensor 7 is 0, and then calculate the retractable length of the cable at this time to be 0 based on the data, and set The calculated retractable length is used as the initial value;

[0036] Step 2: First select the automatic tensioning function on the control panel of the towing winch, and then set the maximum retractable length of the rope on the basis of the above initial value, and send out the brake control command, which is passed through the PLC The control system 1 reaches the brake control device 8 after processing, and then the brake control device 8 sets the braking force of the stepless adjustment brake 6 according to the bra...

Abstract

The invention relates to a towing winch with automatic tensioning function; the towing winch comprises a PLC (programmable logic controller) control system, a main power system and a roller, wherein the PLC control system is connected with the main power system; the other end of the main power system is sequentially connected with a pinion gear and a big gear; the roller is provided with a stepless adjusting brake which is connected with the PLC control system; and the big gear is provided with a speed sensor. When the towing winch is used, firstly the PLC control system is started so as tocollect field data, then the automatic tensioning function is selected as the working mode of the PLC (programmable logic controller) control system and finally the maximum gathering length and braking force of a mooring rope is set; when an external load is greater than the braking force in the towing process, the main power system is started to reversely drive the roller so as to realize the gathering of the mooring rope; and when the length of the gathered mooring rope is equal to the maximum gathering length, the main power system stops gathering the mooring rope. The design of the towingwinch can consume few energy sources and has faster response speed; and the towing winch has batter stability and lower failure rate during long-time running.

Description

technical field [0001] The invention relates to a tow cable winch, in particular to a tow cable winch with an automatic tensioning function and a realization method thereof, which is particularly suitable for the towing operation of the towing cable winch with the automatic tensioning function. Background technique [0002] In the field of ocean engineering, when a large-tonnage ship enters or leaves a port or some kind of offshore oil platform and other equipment without self-propelled capability need to move from one position to another, because they cannot rely on themselves to complete this work, at this time generally It is done by a special towing boat. When the towing ship is performing towing operations, the ship is generally equipped with several towing winches. The towed ship and the towing ship are connected by cables, and the cables are wound on the towing winches. To control the moving speed of the towed ship. [0003] During long-distance towing operations, i...
