Description

Technical Field

[0001] The invention mainly relates to the technical field of ship navigation marks, and in particular to an auxiliary hook device for lifting an offshore light buoy. Background Art

[0002] Navigation mark is the abbreviation of aids to navigation, which refers to the marks indicating the direction, boundaries and obstacles of the waterway, also called signal buoys, including river crossing marks, coastal marks, guide marks, transition guide marks, bow and stern guide marks, side marks, left and right navigation marks, position markers, flood marks and bridge and culvert marks, etc. They are artificial marks that help guide ships to navigate, locate and mark obstacles and indicate warnings.

[0003] At present, navigation mark hook operation generally adopts two operation forms:

[0004] One operation mode is two people working together, one person pushes the hook with a half-moon hook, and the other pulls the traction rope connected to the hook to adjust the hook opening direction to face downward, and both people work together to push the hook to the lifting ear;

[0005] Another mode is that because the hook is heavy and difficult to control, a simple threading device is used. The threading device is connected to the traction rope. One operator uses a hard rod to pass the threading device through the lifting lug, and another operator uses a half-moon hook to hook the traction device pull ring passing through the lifting lug, pull the traction device back to the ship, and then pull the traction rope to pull the hook to the buoy lifting lug and hook it smoothly;

[0006] Generally, when the wind and wave conditions are good, two navigation workers who cooperate well with each other need to try to hang the buoy on the side of the ship several times before they can succeed. Due to wind direction, current direction and other factors at sea, the relative position of the ship and the buoy is unstable and the buoy shakes irregularly, so other people are needed to help fix the buoy and reduce the degree of shaking of the buoy.

[0007] The inventor discovered the following defects during the operation of the specific embodiment:

[0008] The existing navigation mark hooking operation takes up a lot of human resources. The whole hooking operation requires a total of 4 people, or at least 3 people. The personnel need to cooperate tacitly to complete the hooking operation. Especially in bad weather, the buoy shakes, making it difficult to carry out the hooking operation effectively. Summary of the invention

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items. Example

[0037] See attached Figure 1-5 The auxiliary hook device for offshore light buoy lifting operation includes a direction adjustment device 1, which is detachably connected to a guide rod 2. A slide groove is provided on the top of the guide rod 2, and the slide groove is matched and connected to a first support plate 3. The first support plate 3 is detachably connected to one end of a second support plate 4, and the other end of the second support plate 4 is slidably connected to the bottom of the guide rod 2.

[0038] The direction adjustment device 1, guide rod 2, first support plate 3, and second support plate 4 are all made of titanium alloy. Considering the marine operating environment of the ship, there will be a lot of impurities such as mud and sand on the deck. At the same time, it is necessary to ensure that the device does not deform under continuous reset impact and ensure the active reset of the movable plate. After comparing many materials, titanium alloy is selected as the main manufacturing material. The density is 4.057 (g / cm^3), the hardness is HBS60≈67, and the corrosion resistance is good. After three-dimensional software simulation calculation, the overall design weight is ≈3.6kg, which meets the work requirements. Therefore, titanium alloy is selected as the material of the equipment after comparison.

[0039] The direction adjustment device 1 includes a support rod 101, the top of the support rod 101 is fixedly connected to a coupling block 102, a first coupling hole 103 is provided in the middle of the coupling block 102, the first coupling hole 103 matches and connects one end of a symmetrically set semicircular block 104, the other end of the semicircular block 104 is fixedly connected to a rotating shaft 105, and the rotating shaft 105 is threadedly connected to the guide rod 2. Since the measured height space of the buoy lifting ear is about 13 cm, and the width of the hook device body is about 11 cm, when the angle between the device and the lifting ear is greater than 15 degrees, the front section of the hook will collide with the buoy drum surface and cannot smoothly hook the lifting ear. The horizontal movement of the hook device is the best operating angle of the device. Therefore, an angle adjustment device is designed to be added at the connection between the hook and the rod to ensure that the device can maintain the best working angle at any angle. When in use, the coupling block 102 and the semicircular block 104 are connected through the first coupling hole 103 by a locking screw according to actual conditions, and the appropriate angle is adjusted by the locking screw.

[0040] Slide blocks 301 are provided on both sides of the top of the first support plate 3, and the slide blocks 301 are slidably connected to the slide groove. A connecting hole 302 is opened at the bottom of the slide block 301, and the connecting hole 302 can be hung with a steel wire rope. A first combining column 303 is provided at the bottom of the connecting hole 302, and a second combining hole 304 is provided at the bottom of the first combining column 303. When the buoy ring passes through the second support plate 4, the device continues to be pulled toward the ship. At this time, the buoy ring will hit the right side of the first support plate 3. Under the action of the impact force, the first support plate 3 slides out of the guide rod 2 through the slide block 301. After sliding out, the steel wire rope hung in the connecting hole 302 is convenient for the buoy ring to be hung. At the same time, the first support plate 3 rebounds and slides into the guide rod 2 under the action of the elastic member.

[0041] The second support plate 4 includes a quasi-triangular plate 401, one side of which is in an arc shape, and U-shaped grooves 402 are provided on both sides of the top of the quasi-triangular plate 401, and the U-shaped grooves 402 are slidably connected to the inner side of the bottom of the guide rod 2, and the left side of the quasi-triangular plate 401 is in a square block shape, and a groove is provided on the left side of the quasi-triangular plate 401, and third combining holes 403 are provided on both sides of the groove, and the third combining holes 403 match the second combining holes 304, and a second combining column 404 is provided on the right side of the third combining hole 403, and the first combining column 303 is connected to the second combining column 404 through an elastic member, when the buoy hanging ring hits the second support plate 4, under the action of force, the U-shaped groove 402 will slide out of the guide rod 2, thereby sending the buoy hanging ring into the interior, and then the second support plate 4 returns to the guide rod 2 under the action of the elastic member.

[0042] In order to ensure that the guide rod 2 and the second support plate 4 are completely reset, a U-shaped groove is added to the support plate to perform a guiding function, and a rounded corner transition is added at the disengaged and closed position to reduce the occurrence of burrs and chamfers.

[0043] The right side slope of the second support plate 4 is 25-35 degrees.

[0044] After accounting and analysis, Figure 5 As shown, when the second support plate 4 hits the buoy ring and makes a circular motion along the support axis in the A direction, the second support plate 4 can be detached from the guide rod 2 only when F1x>F2x. F1x and F2x are the component forces of F1 and F2 on the x-axis and have the same angle, so as long as F1>F2, that is, the angle a is between 0-45°; at the same time, considering that the thickness of the buoy ring is about 40mm, the vertical distance between the support plate and the guide rod 2 cannot be too small, and the slope angle of the front end of the second support plate 4 is selected to be 25~35 degrees.

[0045] The middle part of the second support plate 4 is a hollow structure to reduce the weight of the device.

[0046] The third combining hole 403 is connected to the second combining hole 304 via a fixing shaft, and the fixing shaft is a detachable structure for easy disassembly.

[0047] To sum up, the present invention is reasonably designed. When in use, the cable is connected to the connecting hole. The direction adjustment device is controlled to be connected to the guide rod and the angle is adjusted according to actual conditions, so that the device can move horizontally on the buoy ring, and the first support plate is connected to the second support plate and the guide rod. When working, the second support rod hits the buoy ring, and the elastic part stretches the second support plate to disengage clockwise with the fixed axis as the center. When the buoy ring passes through the second support plate, the stretching spring is reset, and the buoy ring continues to hit the first support plate. The elastic part stretches the first support plate to disengage with the fixed axis as the center, and the first support plate carries the traction rope through the ring to complete the entire rope threading operation.

[0048] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
