Immersed tube traverse mooring winch and system

Abstract

The invention relates to the technical field of over-water construction cable system equipment, and provides a sinking tube sidesway mooring winch and system. The winch comprises a common base and a positioning pile, wherein the common base is hinged to the positioning pile; the common base is provided with a motor, a transmission unit and a winding drum unit, wherein the motor, the transmission unit and the winding drum unit are connected in sequence; the winding drum unit comprises a main winding drum and an auxiliary winding drum; the main winding drum and the auxiliary winding drum are respectively connected with the transmission unit via a main clutch and an auxiliary clutch. According to the sinking tube sidesway mooring winch, a cable of the sinking tube sidesway mooring winch can realize multidirectional traction through the rotatable common base so as to meet various traction requirements of a tube joint and a dock gate of a sinking tube in a dock chamber. On the basis, the winding drum unit capable of realizing self cable discharging is also designed for the winch, and a main steel wire rope can be taken to a destination on a far position by an auxiliary steel wire rope wound on the drums. The sinking tube sidesway mooring system with the winch is convenient in operation and can adapt to various operation requirements in the dock chamber with a large area.

Description

technical field [0001] The invention relates to the technical field of cable equipment for water construction, in particular to an immersed tube lateral movement mooring winch and system. Background technique [0002] Mooring equipment is part of marine equipment and is suitable for water work and offshore construction environments. It is a more suitable choice to design and manufacture pipe section traverse mooring twisted cable system equipment by adopting offshore ship equipment standards. One of the more reasonable prefabricated immersed tube docks and the distribution of the traversing mooring cable system can be found in figure 1 . In the figure, the deep dock area 34 is located on the north side of the dock chamber, and the shallow dock area 35 is located on the south side of the dock chamber; closed; the east side of the shallow dock area 35 is isolated from the factory area 40 by the shallow dock steel gate 36. In addition, the traversing mooring twisted cable s...

Problems solved by technology

However, the winch in the current winch subsystem has a single cable outlet position, and it is difficult to adapt to the various operating requirements of the immersed tube joint 33 and the dock door at the same time; Used for undocking of pipe joints and opening and closing of dock doors

In addition, due to the large area of ​​the dock room, it is necessary for the winch to be able to unload the cable over a long distance; however, the wire rope unloading of the current winch cannot be realized automatically, and because the cable is difficult to pull out manually, it is necessary to set up an auxiliary power machine to achieve this.
