Description

TECHNICAL FIELD

[0002] The automatic rudder, full name "automatic steering device control system", also known as "automatic steering device", refers to a steering device that can automatically and timely correct the deviation of the ship, so that the ship can be kept on the specified course for a long time and accurately. The working principle is: when the bow is deviated from the original course by a certain angle under the action of wind, wave, current and other external forces, the device immediately acts to deflect the rudder by a certain angle, and the bow gradually returns to the original course under the action of the rudder force; in order to prevent the inertia of the bow from being too large, the device makes the rudder normal or produces an anti-rudder angle when the bow is close to the original course, so that the bow returns to the original course. The automatic rudder is a closed loop system, which includes: a course setting link; a course detection link; a given course and actual course comparison link; a course deviation and rudder angle feedback comparison link; a controller; an execution mechanism; a rudder; a ship as a regulated object; a rudder angle feedback mechanism, etc.

[0032] Specifically, the main body of the connecting piece 1 is the first panel 11 and the second panel 12 arranged in parallel; one side of the first panel 11 and the second panel 12 is welded and fixed with the support 3, and the other side is welded with the first web 13 to play a supporting role, thereby improving the structural stability of the connecting piece 1; according to different installation environments, the size and thickness of the first panel 11 and the second panel 12 can be selected in different sizes, so as to reduce the occupied space size and the weight of the connecting piece 1 itself; and the welding position of the connecting piece 1 and the support 3 can be selected according to the actual position of the rudder handle 5, so that the mounting piece 2 and the feedback mechanism 4 thereon are closer to the rudder handle 5 in height position, and the volume of the transmission structure 42 between the rudder handle 5 and the feedback mechanism 4 is smaller, occupying less rudder cabin space. The main body of the mounting piece 2 is the third panel 21 and the fourth panel 22, one side of the third panel 21 is fixedly connected with the connecting piece 1, and the other side is connected with the fourth panel 22 through the second web 23; the two ends of the second web 23 are fixed at the middle positions of the third panel 21 and the fourth panel 22; the third panel 21 and the fourth panel 22 are the main components for bearing the feedback mechanism 4, and are provided with the mounting plate 24 for fixing the feedback mechanism 4; the second web 23 is vertically arranged between the third panel 21 and the fourth panel 22, and is perpendicular to the mounting plate 24, which can better share the weight of the feedback mechanism 4, ensure the stability of the feedback mechanism 4, so that the feedback mechanism 4 will not have the problems of position deviation or drop, and ensure the stable detection and feedback of the feedback mechanism 4 to the rudder angle.

[0033] In some embodiments, the side of the first panel 11 and the second panel 12 away from the first web 13 is provided with an arc-shaped mounting groove 14, and the support 3 is embedded in the mounting groove 14; the support 3 is welded and fixed with the first panel 11 and the second panel 12.

[0034] Specifically, in the actual processing process, the outer diameter of the support column 3 can be cut on the first panel 11 and the second panel 12 first, and then the first web plate 13 is welded and fixed on the other side of the first panel 11 and the second panel 12, so that the two mounting grooves 14 are coaxial, then the support column 3 is embedded in the mounting groove 14, and the connector 1 is adjusted to the appropriate height position along the axis of the support column 3, and finally the first panel 11 and the second panel 12 are welded and fixed with the support column 3.

[0035] In some embodiments, two first reinforcing ribs 15 are further arranged between the first panel 11 and the second panel 12, one end of the first reinforcing rib 15 is fixedly connected with the first web plate 13, and the other end is welded and fixed with the support column 3.

[0036] Specifically, the first reinforcing rib 15 is arranged between the first panel 11 and the second panel 12, which can strengthen the structural stability of the connector 1, avoid the middle part of the connector 1 from being concave due to the lack of support points, and further affect the structural stability of the welding position of the first panel 11 and the second panel 12 with the support column 3. In addition, the two first reinforcing ribs 15 can be welded and fixed with the support column 3, further strengthening the stability of the connection between the connector 1 and the support column 3.

[0037] As shown in Figure 4 In some embodiments, the connector 1 is provided with two mounting grooves 14, which are semicircular grooves, and the two connectors 1 are symmetrically arranged along the axis of the support column 3, and the two connectors 1 are correspondingly welded and fixed.

[0038] Specifically, the mounting grooves 14 on the two connectors 1 symmetrically arranged along the axis of the support column 3 can be combined to form a complete circular through groove, and the positions corresponding to the abutment between the two connectors 1 are also welded and fixed, which can further strengthen the stability of the connection between the connector 1 and the support column 3, and make the stress condition between the connector 1 and the mounting member 2 more balanced, and not easy to appear the situation that the connection is damaged due to too large torque.

[0039] In some embodiments, the second panel 12 is fixedly provided with a support rod 16 away from the first panel 11, the other end of the support rod 16 is welded and fixed with the support column 3, and the support rod 16 is circumferentially provided with a plurality of support rods 16 around the axis of the support column 3.

[0040] Specifically, the two ends of the support rod 16 are respectively welded and fixed with the second panel 12 and the support column 3, thereby providing support for the second panel 12 and the connecting piece 1, avoiding the problem that the connecting piece 1 is far away from the support column 3 and the connecting part between the connecting piece 1 and the support column 3 is subjected to excessive force. The top of the support rod 16 is welded and fixed to the bottom of the second panel 12 near one side of the first web plate 13, so as to better provide support for the connecting piece 1. In addition, the surrounding arrangement of the support rod 16 can also provide better support for the two connecting pieces 1, avoiding the problem of uneven force on one side.

[0041] In some embodiments, the third panel 21 is welded and fixed with the first panel 11, the second panel 12, and the first web plate 13; the side of the first panel 11 away from the second panel 12 is provided with a third reinforcing rib 17, and the third reinforcing rib 17 is welded and fixed with the third panel 21.

[0042] Specifically, in the actual installation process, after the connecting piece 1 and the mounting piece 2 are variously welded, the relative positions of the connecting piece 1 and the mounting piece 2 are adjusted, and the first panel 11 and the second panel 12 are welded and fixed with the third panel 21. The third reinforcing rib 17 is welded and fixed with the first panel 11 and the third panel 21, respectively, to reinforce the stability of the connection between the first panel 11 and the third panel 21. Further, the third reinforcing rib 17 can also be arranged between the second panel 12 and the third panel 21 to reinforce the stability of the connection between the second panel 12 and the third panel 21.

[0043] In some other embodiments, the connecting piece 1 further comprises a connecting plate provided with a first mounting hole, and the third panel 21 is provided with a second mounting hole corresponding to the first mounting hole, and the third panel 21 and the connecting plate are fixedly connected through bolts.

[0044] Specifically, the connecting piece 1 and the mounting piece 2 are no longer welded and fixed, but are locked through a bolt structure. Under this structure, the mounting piece 2 can be more conveniently detached from the connecting piece 1, thereby facilitating the preliminary maintenance of the feedback structure. Further, the third panel 21 can be provided with multiple second mounting holes or longer waist-shaped holes to facilitate more accurate adjustment of the positions of the mounting piece 2 and the connecting piece 1.

[0045] In some embodiments, the third panel 21 is provided with a limiting groove 211 for accommodating the wire harness of the limiting feedback mechanism 4. The limiting groove 211 can limit the positions of the output wire harness and the input wire harness of the feedback mechanism 4, ensure the neat appearance of the entire structure, and avoid the problems of space occupation caused by random placement of the wire harness and loosening caused by pulling of the wire harness by other structures.

[0046] In some embodiments, the second web plate 23 is fixed with a bottom plate 25 away from one side of the mounting plate 24, and the second reinforcing rib 26 is arranged between the third panel 21 and the fourth panel 22 and the bottom plate 25, and the second reinforcing rib 26 is welded and fixed with the bottom plate 25, the second web plate 23, and the third panel 21 or the fourth panel 22.

[0047] Specifically, the second reinforcing rib 26 can enhance the connection strength between the third panel or the fourth panel 22 and the bottom plate 25, that is, increase the overall structural strength and stability of the mounting member 2.

[0048] In some embodiments, the surface of the connecting member 1 and the mounting member 2 is hot-dip galvanized with a first corrosion-resistant layer; and the connecting member 1 and the mounting member 2 are welded and sprayed with a second corrosion-resistant layer.

[0049] Specifically, in the actual installation process, after the connecting member 1 and the mounting member 2 are respectively processed and welded, the connecting member 1 and the mounting member 2 can be hot-dip galvanized to attach a layer of corrosion-resistant alloy zinc layer as the first corrosion-resistant layer of the inner layer, and then the connecting member 1 and the mounting member 2 are sequentially welded and fixed on the support 3, and then the second corrosion-resistant layer is sprayed on the surface of the support 3, the connecting member 1 and the mounting member 2 as the outermost wear-resistant corrosion-resistant measure, further protecting the connection between the connecting member 1 and the mounting member 2 and the support 3, especially the welded part, to avoid corrosion and damage to the connecting member 1 and the mounting member 2.

[0050] As shown in Figure 5 and Figure 6 In some embodiments, the second web plate 23 is provided with a U-shaped hollow area 27, and the opening of the hollow area 27 faces the mounting plate 24. Specifically, the hollow area 27 can further reduce the material cost and reduce the weight of the mounting member 2 on one hand; on the other hand, since the bottom of the feedback mechanism 4 is connected with the tiller 5 through the connecting rod, the rotation of the tiller 5 will also drive the rotation of the angle measuring device in the feedback mechanism 4 through the transmission structure 42, and the arrangement of the hollow area 27 can facilitate the rotation of the transmission structure 42 and avoid interference and collision problems.

[0051] In summary, the embodiment of the present application provides a fixed base of a rudder feedback mechanism 4, which fixes the mounting part 2 and the feedback mechanism 4 thereon on the rudder cabin support column 3 through the connecting part 1, avoids the problems of too large height difference, too large structure volume and too much occupied space caused by setting the base on the ground of the rudder cabin, makes the height difference between the mounting part 2 and the feedback mechanism 4 thereon and the rudder handle 5 smaller, and the distance closer, so that the feedback mechanism 4, the transmission structure 42 thereof, the mounting part 2 and the connecting part 1 and other structures can be made smaller, not only reduces the occupied space, but also releases the space at the bottom of the rudder cabin, and the space utilization is higher; in addition, since the connecting part 1 and the mounting part 2 are both made of plates, they are not only small in volume, but also low in cost and simple in manufacturing.

[0052] The above only describes the preferred embodiments of the present application, and it should be noted that those skilled in the art can make several improvements and replacements without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection scope of the present application.
