Auxiliary device for icebreaker

Abstract

The invention discloses an auxiliary device for an icebreaker, which includes a connecting frame and a mechanical frame. A motor and a reducer are arranged on the frame, and a main shaft is arranged in the mechanical frame. A limit bar is set, and a positioning screw is set on the spur wheel; a sling is set on the mechanical frame, and a hoist is set on the bow, and the sling is connected to the hoist; the advantage of the present invention is that the ice layer can be easily broken and the icebreaker can be pulled forward , greatly improving the ice-breaking efficiency and ice-breaking thickness.

Description

technical field [0001] The invention relates to an icebreaker, in particular to an auxiliary device capable of breaking the ice layer easily and pulling the icebreaker forward. Background technique [0002] An icebreaker is a service ship used to break the ice on the water surface, open up waterways, ensure that ships enter and leave ice-covered ports and anchorages, or guide ships to sail in ice areas. The methods include ice-breaking and impact methods; the application number is CN201110326606 invention patent A continuous ice-breaking mechanism is disclosed, which is characterized in that it includes a gear (1), a toothed wheel bracket (2), a bearing (3), a toothed wheel shaft (4) and a bracket (5), wherein the toothed wheel (1 ) is connected with the toothed wheel shaft (4), the toothed wheel shaft (4) is connected with the toothed continuous bracket (2) through the bearing (3), and the bracket (5) is arranged on both sides of the lower part of the toothed wheel (1); thi...

[0003] The patent for invention with the application number CN201310193717.8 discloses the combined ice-breaking equipment and method of grooving and hull pressure, a combined ice-breaking equipment of grooving and hull pressure, including an icebreaker, which is characterized in that: each side of the hull of the icebreaker is provided with a Ice-breaking device, the ice-breaking device comprises an outrigger, a milling cutter arranged on the outrigger and a power unit connected to the milling cutter on the outrigger, the axial direction of the milling cutter is the width direction of the icebreaker, and the icebreaker hull It is located between the two milling cutters of the two ice-breaking devices, and the two milling cutters of the two outriggers are all located on the front side of the icebreaker hull; this invention is theoretically possible, but it is difficult to use the milling cutter to cut grooves on the hard ice surface. The speed must be slow, which will definitely affect the forward speed of the icebreaker, which also reduces the icebreaking efficiency; two milling cutters cut two grooves on both sides of the icebreaker, but the main factor of icebreaking is to use the weight of the icebreaker to break the ice surface. The broken breakthrough is in the front middle of the bow, and the grooves of this invention are on both sides of the icebreaker. This design is not helpful for icebreaking; and it cannot bring additional traction for the advancement of the icebreaker
