Problems solved by technology

In the existing technology, the patent No. 96198742.1 is the patent of "tugboat with horizontal propulsion device". The tugboat is equipped with two propulsion devices at the stern and one propulsion device at the bow, but the bow does not have the capability of side thrusting. It only has the advantages of flexible operation and fuel saving, but does not have the function and operation mode of side thruster

Embodiment Construction

[0014] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 , figure 2 As shown, the propulsion device of the present invention includes a first propulsion device 1 , a second propulsion device 2 and a third propulsion device 3 . The horizontal propulsion directions of the three propulsion units are perpendicular to the respective axes C1, C2, C3, and each propulsion unit is driven by an independent engine. Wherein the first propulsion device 1 and the second propulsion device 2 are arranged on the stern 8, and their central vertical axes C1, C2 are symmetrical to the longitudinal axis of symmetry 4, and their thrust is toward the rear of the hull, and its function is the same as that of a common tugboat. The third propulsion device 3 adopts a transverse propulsion device and is installed on the bow 9 of the tugboat, and its central vertical axis C3 is located on the mai...

Abstract

The invention a side-pushing towboat whose bow has lifting transverse thruster, installed with three pushers, where two pushers are installed in the stern and have the same function as the general ships. The third pusher is a transverse pusher in the bow, to make the towboat have side-push working function. When the bow is inserted in the gap between the offshore-being ship and the dock, the transverse pusher starts working, the thrust produced is perpendicular to the primary plane of the vertical symmetric axis of the towboat, acting on the bow of the offshore-being ship, to make it gradually leave the dock so as to enlarge the space between the ship and the dock for creating conditions of towboat thrusting. It can flexibly turn and turn round on the water surface, easy to near work.

Description

technical field [0001] The invention relates to a side-thrusting tugboat, in particular to a side-throwing tugboat with a lift-type transverse propulsion device at the bow, and belongs to the technical field of ship engineering. Background technique [0002] Existing various tugboats at present, comprise ocean-going tugboats, coastal tugboats, inland river tugboats and port work tugboats, all do not have propelling device installed in the bow, only have two kinds of operation modes of towing and pushing. When the ship is required to leave the shore, due to the narrow gap between its bow and the shoreline, it cannot accommodate the length of the tugboat, so that the tugboat cannot carry out the pushing operation. The only way of operation is to transfer to the outside of the ship and pull the bow of the ship with a steel cable. When the object to be towed is too tall, or the water surface of the towing operation is narrow, the operation of receiving the throwing steel cable ...
