Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Combining Figure 1 and Figure 3, during the towing process of the existing towing machine, the emergency release is realized mainly by disengaging the jaw clutch 7 on the drive shaft, so that the power mechanism of the towing machine is disconnected from the actuator . If it is necessary to realize the emergency release during the towing process of the upper drum 52, the upper jaw clutch control device 74 must be manipulated to disengage the upper jaw clutch 71, so that the upper drum 52 is in a free state, thereby realizing the emergency release of the upper drum 52. Similarly, emergency release of the lower drum 62 can also be performed. But because the torque transmitted in the process of dragging is very large, the upper jaw clutch 71 or the lower jaw clutch 73 are often stuck very tightly, and it is difficult to open it i...

Abstract

The invention relates to a marine haulage device and an emergency release method thereof, which belong to the technical field of marine machines. An upper roller clutch (3) is mounted on the output shaft of an upper roller-driving motor (5), a lower roller clutch (4) is mounted on the output shaft of a lower roller-driving motor (6), the output ends of the upper roller clutch (3) and the lower roller clutch (4) are respectively and fixedly connected with small gears (1), the control end of the upper roller clutch (3) is connected with an upper roller clutch controller (54), and the control end of the lower roller clutch (4) is connected with a lower roller clutch controller (64). The upper roller clutch (3) and the lower roller clutch (4) can be synchronously disengaged to carry out emergency release. The transmission torque of the clutches is low, action is quick, sensitivity is high, the clutches can be quickly engaged and disengaged, operation is flexible and reliable, and thereby the invention can fully meet the requirement of International and domestic emergency release action standards.

Description

technical field [0001] The invention relates to a marine towing device, and also relates to an emergency release method for the device, in particular to a marine towing device and an emergency release method thereof. It belongs to the technical field of marine machinery. Background technique [0002] Marine three-purpose engineering marine towing winch is designed for effective and safe towing, anchor handling and other work of marine engineering ships, and is installed on the deck of the ship. According to the international standard ISO 7365-1983 "Shipbuilding and Marine Equipment - Deck Machinery - Towing Winch for Ocean-going Vessels" and the national standard of the People's Republic of China "Towing Winch for Ocean-going Vessels" GB 11869-89, the towing winch should have an emergency release function , that is, it should be designed so that the drum can be released in an emergency when the rope is taken in, released or the drum is braked. The maximum delay time allowe...
