The rail is arranged below the arm support 100, one end of the cable rope 13 is connected with the cargo 200 in operation, the other end of the cable rope is controlled by the cable winch 11, and the cable trolley assembly 3 is driven by the traction winch 21 to move back and forth on the arm support 100 along the rail through winding of the steel wire rope 23, so that the cable effect is ensured to meet the design requirement.
In the process of lifting the goods 200, as shown in fig. 4, the motion of the cable wind trolley assembly 3 is automatically compensated and driven to different proper positions along with the height change of the goods 200 by comprehensively controlling the traction winch 21, so that the rope outlet direction of the cable wind rope 13 is always controlled to be as close to the height of the lifting point as possible, the effect that the tension of the cable wind rope 13 tends to be horizontal is basically achieved, and the maximum effect of the force of the cable wind rope 13 is ensured all the time. Thus, the balance effect of the goods 200 is remarkably improved in the operation process, the goods 200 is easy to control, and the efficiency of installing the goods 200 is greatly improved.
The offshore crane trolley cable wind rope device can greatly enlarge the window period of construction operation and greatly improve the construction efficiency.
As shown in connection with fig. 6, the cable wind trolley assembly 3 comprises a trolley frame 31, a trolley pulley 32 and a guide 33 arranged at the lengthwise end of the trolley frame 31, a traction pulley 34 arranged at the widthwise end of the trolley frame 31, wheels 35 arranged at the bottom of the trolley frame 31, and horizontal wheels 36 arranged at the sides of the trolley frame 31.
The cable car assembly 3 moves along the rail through the wheels 35, and the movement of the cable car assembly 3 is prevented through the cooperation of the horizontal wheels 36 and the rail.
Except for the goods stabilizing pulley 32, the traction pulley 34 and the navigator 33, other structures are formed by steel structural members through welding.
The navigator 33 can realize the rope outlet point direction of the cable rope 13 in various directions.
The pulley assembly 12 of the wind-wrapping unit 1 is arranged in a combination of a single pulley and two pulleys arranged side by side.
In the pulley assembly 12, the pulley is properly specified according to design requirements, the pulley frame is formed by welding steel structural members, and the pulley frame can be welded at different positions of the arm frame 100 according to the trend of the cable ropes 13 in different cable wind winding units 1, so that the different trend of the cable ropes 13 is changed.

The cable rope 13 is wound on the stabilizing pulley 32, and the rope-out direction is changed by the navigator 33.
The wire rope 23 is wound around a traction sheave 34.
In combination with the illustration of fig. 5, two parallel pulley assemblies are arranged more than the conventional pulley arrangement, and are arranged at the position (near the front end head position of the arm frame 100) further forward than the 3-stroke limit position of the cable car assembly, and the pulley block is at the highest position in cable winding when lifting the suspended object.

When the cable 13 is in operation, the cable 13 transfers force to the cable car assembly 3: the maximum cable rope force F is upwards, the force of the cable rope which is downwards stable is F ranging from 0 to 1, the total force F1 of the cable rope 13 borne by the comprehensive cable trolley assembly 3 is F ranging from 0 to 1 upwards, the cable trolley assembly 3 has a downward self gravity G, if factors such as an arm support angle and pulley efficiency are not considered, the final trolley traction force F2 on the cable trolley assembly 3 is G-2 (0 to 1) F, and therefore the comprehensive stress F1 at the cable trolley assembly 3 is greatly smaller than the stress of other trend arrangement schemes, the cable trolley assembly 3 can be designed as light as possible, the traction force F2 of the total cable trolley assembly 3 is greatly optimized to be smaller, and the maximum traction force of a traction winch of the cable trolley assembly 3 is designed without being set to be too large; compared with the common design, the wind rope 13 has the advantages that the trend is not too much longer, and the design cost is saved to a certain extent.
Taking a wind power installation floating crane as an example, a set of cable wind rope system with two-point tension not less than 10T and suitable for integrally hoisting and stabilizing a wind wheel of a 15 MW-20 MW fan is manufactured:
the guy wires 13 on the guy car assembly 3 come from the head of the boom 100, the purpose of such entanglement being to optimise and reduce the total force F1 of the guy wires 13 on the guy car assembly 3 and the traction force F2 of the guy car assembly 3. When the cable 13 is in operation, the cable 13 transfers force to the cable car assembly 3: the maximum cable rope force is 2 x 10T upwards, the cable rope force for downward cable rope stabilization is 0T-2 x 10T (along with the cable rope outlet angle change of the cable guider), and the total force F1 of the cable rope 13 borne by the comprehensive cable trolley assembly 3 is 0T-2 x 10T. The cable wind trolley assembly 3 has a downward self gravity G of about 15T, and if the factors such as the angle of the arm support, the pulley efficiency and the like are not considered, the final trolley traction force F2 on the cable wind trolley assembly 3 is-5T-15T. In contrast, if the wind is wound according to the traditional wind rope winding mode, the total force F1 of the wind rope borne by the wind trolley assembly 3 is 20T-40T, the traction force F2 of the wind trolley assembly 3 is 35T-55T, and the comprehensive stress F1 of the wind trolley assembly 3 is greatly optimized and reduced compared with other trend arrangement stress according to the data, so that the wind trolley assembly 3 can be designed in a light-weight manner as much as possible, and in addition, the traction force F2 of the total wind trolley assembly 3 is greatly optimized and reduced, and the maximum traction force of a traction winch of the wind trolley assembly 3 is not required to be set too large.
When the two sets of cable wind winding units 1 are idle, the single-side cable ropes 13 can be used as hooks with the tension of not more than 10 tons. The cable trolley assembly 3 can also be used as a crane that can travel along a track arranged under the boom 100.
The cable wind unit 1 needs to have the functions of speed control, moment control, synchronous position control and the like, and needs to consider the response speed of the system so as to achieve balance and stability control on the heavy objects in the hoisting process.
