Description

technical field [0001] The invention relates to a control device and control method of an electric cable storage winch, more specifically, relates to a storage and discharge for steel wire ropes or photoelectric composite load-bearing cables with a certain hardness, which is realized by a programmable controller A control device and a control method for an electric cable storage winch. Background technique [0002] The winch is a common transmission equipment. Since the wire rope has sufficient strength and hardness, it is not afraid of extrusion deformation and has high safety. Therefore, most of the wire rope is used to connect the winch and the dragged object. When the length of the cable is several thousand meters, the weight of the steel wire rope itself will inevitably increase the driving power greatly, and if the dragged object itself needs power supply and optical fiber communication, the steel wire rope cannot meet the requirements of use. At this time, it is often...

Problems solved by technology

[0003] When the cable is to realize multi-turn, multi-layer cable storage or cable discharge on the cable storage winch, a cable discharge guide wheel driven by a screw rod is required to reciprocate on the screw rod. The traditional way of driving the screw rod is the cable discharge screw rod and Chain transmission is adopted between the cable storage reels, and the cable storage reel is driven by a motor, which drives the screw to move through the chain transmission. The advantage of this is that the system is simple and the screw does not need to be controlled independently, but the disadvantages are also obvious, mainly as follows Points: 1) The system is not flexible and cannot adapt to cables of different diameters. If it is replaced with cables of different diameters, it is necessary to redesign and manufacture screw rods with different pitches; The wheel needs to reciprocate left and right under the drive of the cable discharge screw. The cable discharge screw needs to be designed as a two-way screw, which increases the difficulty and cost of manufacturing; 3) due to manufacturing and assembly errors, the storage and discharge of cables are easy to cause irregularities. It is often necessary to stop and manually assist the cable arrangement, which is inefficient. In severe cases, the screw rod may need to be redesigned and manufactured; 4) Since the cable discharge screw rod and the cable storage drum are connected by a chain, the cable guide wheel needs to be adjusted when parking is required. In the position of the cable screw rod, the chain must be disassembled to separate it from the sprocket, and the adjustment handwheel at the end of the cable screw rod must be manually turned. The whole process is very time-consuming and laborious.

[0004] As the winch task system puts forward higher and higher requirements for the control device of the cable storage winch, the conventional control device of the cable storage winch can no longer meet the requirements. The key to solving the problem is to adopt a new control device and a new control method generated by it where the
