Problems solved by technology
[0003] At present, the existing single-drum winch cannot meet the needs of deep-water offshore oil pipe-laying operations. First of all, due to the large traction force of the winch required for deep-water pipe-laying, the existing single-drum winch cannot meet such a large traction load, while the double-drum winch cannot can tow heavy loads
Furthermore, the current retractable winch has the problems of excessive bearing stress during the traction operation, resulting in serious heating of the bearing and low bearing life.
In addition, if the retractable winch with large tonnage traction is braked, if the internal braking of the motor is used, it does not have such a large braking torque. Even if the motor with internal braking is a rare special motor, the cost of the motor is very high

The invention provides a rendering winch used for deep water pipe laying. The rendering winch comprises a base, a frame, two rotary drums, a plurality of driving devices and a pressure-resistant wheel, wherein the frame is arranged on the base, and the frame is provided with the two rotary drums; the rotary drums are respectively connected with the driving devices, and the driving devices are arranged on the base and positioned on two sides of the frame; and the pressure-resistant wheel is arranged on the frame and positioned between the two rotary drums. The rendering winch provided by the invention has the efficacies of large-tonnage traction force, reliability in braking and high cost performance, and is suitable for being used in deep water pipe laying operation.
Description
technical field [0001] The invention relates to offshore pipe laying equipment, in particular to a retractable winch for laying deep water sea pipes. Background technique [0002] Retractable winches are usually used for traction of heavy objects. This type of equipment is one of the important equipment for offshore pipe-laying ships. It is used to pull the pipeline during the pipe collection or abandonment operation when laying the submarine pipeline. Especially when the pipe needs to be collected or abandoned in the deep water pipelaying operation, since the suspension length of the pipeline from the pipelaying ship to the seabed is very long, the winch needs to have a large traction force, and the The winch is required to have good and reliable braking performance. [0003] At present, the existing single-drum winch cannot meet the needs of deep-water offshore oil pipe-laying operations. First of all, because the deep-water pipe-laying requires the winch to have a larg...
