Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a ship windlass. Background Art

[0002] Ships are vehicles that can sail or anchor in waters for transportation and other operations. In order to achieve the anchoring of ships, windlasses are usually used nowadays. The anchor is the main component of the anchoring equipment. It is an iron ship-stopping device that is connected to the ship with an iron chain. The anchor is thrown to the bottom of the water to make the ship stop steadily. The anchor chain, as a special chain that connects the anchor and the hull and transmits the anchor holding force, plays a vital role in the navigation of the ship. When the anchor chain is used in a ship, there are mainly two states, one is to be rolled up on the ship, and the other is to sink into the water with the anchor.

[0003] The anchor and anchor chain on the ship are both retracted and released by the windlass when in use. In the current windlass technical solution, in the process of retracting and releasing the anchor and anchor chain, since the weight of the anchor and anchor chain themselves is very heavy, when the anchor is lifted, first of all, each layer of the anchor chain is squeezed. During the long-term reciprocating operation, the various metal rings on the anchor chain will inevitably deform, which will directly affect the smoothness of subsequent use. Secondly, when the anchor chain is in use, it is soaked in water for a long time, and some adhesives will adhere to its surface, causing erosion of the anchor chain. At the same time, the adhesives will also make the surface of the anchor chain smooth, and when the anchor is lifted and the anchor chain is rolled up, it is easy to slip.

[0004] Therefore, we propose a ship windlass to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a ship windlass to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A ship anchor windlass comprises a chassis, a cross-shaped hole for an anchor chain to pass through is formed through the top of the chassis, a first motor seat is fixedly mounted on the left side of the chassis, a second motor seat is fixedly mounted on the front side of the chassis, a first motor and a second motor are respectively mounted on the tops of the first motor seat and the second motor seat, a second rotating shaft and a first rotating shaft are respectively butt-mounted on the output shafts of the first motor and the second motor, and an upper gear and a lower gear are respectively mounted on the outer rings of the first rotating shaft and the second rotating shaft.

[0008] Preferably, the upper gear and the lower gear are respectively installed in two adjacent grooves of the cross-shaped hole, and the upper gear and the lower gear are perpendicular to each other.

[0009] Preferably, bearing structures are installed at both ends of the outer rings of the first rotating shaft and the second rotating shaft, and the bearing structures are installed and fixed on the inner wall of the cross-shaped hole.

[0010] Preferably, the spacing between the teeth on the outer walls of the upper gear and the lower gear is greater than the length of a single metal ring on the anchor chain.

[0011] Preferably, the maximum width of the teeth on the outer wall of the upper gear and the lower gear is greater than the length of the inner side of the metal ring on the anchor chain.

[0012] Preferably, the first motor and the second motor are both servo motors with high rigidity.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When the upper gear of the ship's windlass rotates, the teeth on it are inserted into the metal ring which is perpendicular to the upper gear. As the upper gear continues to rotate, the teeth on it will gradually extend into the metal ring, so that the side of the teeth of the upper gear gradually increases the interaction force with the inner wall of the metal ring, so as to achieve uniform force distribution to stretch and shape the metal ring, thereby solving the problem that the anchor chain is deformed due to impact and extrusion during use, which affects the safety of the anchor chain and the smoothness of its retraction and release.

[0015] 2. The ship windlass can be inserted into the metal ring of the anchor chain through the teeth of the gear, and can also remove the adhesion of the anchor chain in the water, so as to avoid the problem of long-term residue on the anchor chain causing erosion of the anchor chain and affecting the safety of use.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a technical solution for a ship anchor windlass:

[0022] Embodiment 1:

[0023] like Figure 1 As shown, the anchor windlass of the present technical solution mainly includes a chassis 1 for the anchor chain to shuttle, a cross-shaped hole 2 for the anchor chain to move is opened in the middle of the chassis 1, a first motor seat 3 is fixedly installed on the left side of the chassis 1, a second motor seat 4 is fixedly installed on the front of the chassis 1, and a first motor 5 and a second motor 6 are installed on the top of the first motor seat 3 and the second motor seat 4 respectively.

[0024] like Figure 3 As shown, the output shaft of the first motor 5 is butt-jointed with the second rotating shaft 8 , and the output shaft of the second motor 6 is butt-jointed with the first rotating shaft 7 .

[0025] An upper gear 9 is mounted on the outer ring of the first rotating shaft 7 , and a lower gear 10 is mounted on the outer ring of the second rotating shaft 8 .

[0026] Both ends of the outer rings of the first rotating shaft 7 and the second rotating shaft 8 are fitted with bearing structures, and the side surfaces of the bearing structures are fixedly mounted to the inner wall of the cross-shaped hole 2 .

[0027] The tooth spacing on the outer wall of the upper gear 9 and the lower gear 10 is greater than the length of the metal ring on the anchor chain. In this way, when the device is used to retract and release the anchor chain, each gear will only act on the metal ring in a perpendicular state, and will not interfere with the metal ring in a parallel state.

[0028] The maximum width of the teeth on the upper gear 9 and the lower gear 10 is greater than the length of the inner ring of the anchor chain metal ring.

[0029] In this embodiment, when the anchor chain retractor of the present technical solution is used, one end of the anchor chain is directly passed through the top of the cross-shaped hole 2 and passed out from the bottom of the chassis 1, and each metal ring of the anchor chain is allowed to enter the cross-shaped hole 2 in a horizontal and vertical manner, and then the first motor 5 and the second motor 6 are started, and the output shafts of the first motor 5 and the second motor 6 respectively drive the first rotating shaft 7 and the second rotating shaft 8 to rotate, and then respectively drive the upper gear 9 and the lower gear 10 to rotate.

[0030] Among them, when the upper gear 9 rotates, the teeth thereon are inserted into the metal ring which is perpendicular to the upper gear. As the upper gear 9 continues to rotate, the teeth thereon will gradually extend into the metal ring, so that the side edges of the teeth of the upper gear 9 gradually increase the interaction force with the inner wall of the metal ring, thereby solving the problem that the anchor chain is deformed due to impact and extrusion during use, which in turn affects the safety of the anchor chain and the smoothness of its retraction and release.

[0031] When the gear teeth begin to squeeze and stretch the metal ring, the metal ring in a perpendicular state is directly pressed against the inner wall of the cross hole 2 to provide support force, while the metal ring parallel to it is located in the groove of the other half of the cross hole 2, and the two do not interfere with each other.

[0032] Likewise, the working mode of the lower gear 10 is the same as that of the upper gear 9, and no additional description is given here.

[0033] Embodiment 2:

[0034] The anchor winch of the present technical solution mainly comprises a chassis 1 for the anchor chain to shuttle, a cross-shaped hole 2 for the anchor chain to move is opened in the middle of the chassis 1, a first motor seat 3 is fixedly installed on the left side of the chassis 1, a second motor seat 4 is fixedly installed on the front of the chassis 1, a first motor 5 and a second motor 6 are respectively installed on the top of the first motor seat 3 and the second motor seat 4, the output shaft of the first motor 5 is butt-mounted with a second rotating shaft 8, the output shaft of the second motor 6 is butt-mounted with a first rotating shaft 7, an upper gear 9 is mounted on the outer ring of the first rotating shaft 7, and a lower expansion gear 10 is mounted on the outer ring of the second rotating shaft 8.

[0035] The first motor 5 and the second motor 6 are both servo motors with high rigidity.

[0036] In the present embodiment, based on the first embodiment, the present technical solution can not only be used alone, but also can be used together with the anchor chain machine, that is, when the anchor chain is retracted and released, especially when the anchor chain is put into the water, the power of the first motor 5 and the second motor 6 is directly used to steadily and slowly put the anchor chain into the water, so that the anchor chain can be shaped while the anchor chain is released, which can effectively solve the problem that the existing anchor chain release speed is prone to get out of control and cause accidents.

[0037] Secondly, by inserting the teeth of the gear into the metal ring of the anchor chain, the sticky materials of the anchor chain in the water can be removed to avoid the problem of long-term residue on the anchor chain causing erosion of the anchor chain and affecting the safety of use.

[0038] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
