Description

Technical Field

[0001] This utility model belongs to the field of marine mast technology, specifically referring to a mast height adjustment device for oil tankers. Background Technology

[0002] A mast is a tall column on a ship that holds sails and flags, mounts antennas, and supports observation posts. It is a long, round wooden pole or a metal column that usually rises vertically from the keel or midships and can support the barges, sail girder, derrick, or girder.

[0003] Existing masts used on oil tankers typically require operators to manually control motors or other power sources to adjust their height during navigation. This requires experienced operators, otherwise the top of the mast may collide with objects and cause damage. To address this, a mast height adjustment device for oil tankers is proposed to reduce the precision required for adjustments by operators and minimize mast damage. Utility Model Content

[0004] The technical problem this invention aims to solve is to reduce the precision required for operators to adjust the mast and to reduce mast damage.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a mast height adjustment device for oil tankers, including a base and a housing disposed on the base, a rectangular shell fixedly disposed on the upper end of the housing, a control panel fixedly disposed on the side wall of the base, a multi-stage lifting assembly disposed inside the housing, and a self-adjusting assembly disposed on the upper end of the rectangular shell;

[0006] The multi-stage lifting assembly includes a servo motor fixedly mounted on the inner wall below the base, and the output end of the servo motor is connected to a rotating shaft for driving the lifting of internal parts of the housing.

[0007] The self-adjusting assembly includes a mast inserted into the upper end of a rectangular shell, and two connecting blocks located inside the rectangular shell are fixedly connected to both sides of the mast in a mirror manner. Electroceramic plates are fixedly connected to the upper inner wall of the shell and the upper end of the connecting blocks, respectively.

[0008] Furthermore, the inner wall of the housing shown is sequentially fitted with a first sleeve post, a first T-shaped post, a T-shaped extrusion block, a second T-shaped post, and a second sleeve post. The rotating shaft is threadedly connected to the center part of the lower end of the sleeve post. A T-shaped extrusion block is rotatably connected to the protrusion on the lower inner wall of the first sleeve post. The inner wall of the T-shaped extrusion block is threadedly connected to the first T-shaped post. A second T-shaped post is rotatably provided at the protrusion on the lower end of the first T-shaped post. The outer wall of the second T-shaped post is threadedly connected to the inner wall of the second sleeve post.

[0009] Furthermore, the upper end of the second sleeve is fixedly connected to an upper cover, and a rectangular shell is fixedly disposed on the upper end of the upper cover.

[0010] Furthermore, an arc-shaped cover is fixedly installed at the upper end of the mast, and springs are sleeved on the outer walls of the two electro-ceramic plates, with the upper and lower ends of the springs respectively fixedly connected to the rectangular shell and the connecting block.

[0011] Furthermore, limit rods are mirror-slidably arranged on both sides of the mast, and the lower ends of the limit rods are fixedly connected to the upper end of the rectangular shell.

[0012] Furthermore, a triangular structure is formed between the mast, the limiting rod, and the rectangular shell.

[0013] The beneficial effects of this utility model by adopting the above structure are as follows:

[0014] 1. Equipped with a multi-stage lifting assembly, the rotating shaft is driven by a servo motor to achieve coordinated lifting of sleeve column one, T-shaped column one, T-shaped extrusion block, T-shaped column two and sleeve column two. The fixed rod with an antenna realizes the lifting function.

[0015] 2. Equipped with a self-adjusting component, when the arc-shaped cover above the fixing rod touches an object, the lower end of the fixing rod moves downward. At this time, the two electro-ceramic plates located at the housing and connecting block separate, generating an electrical signal to control the servo motor to rotate in the opposite direction and pull the fixing rod down until the electro-ceramic plates re-adhere under the action of the spring, and the motor stops. This achieves the function of adaptive adjustment, which can reduce the operator's estimation accuracy of the height of the colliding object and reduce mast damage. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] refer to Figure 1 and Figure 2 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: a mast height adjustment device for oil tankers includes a base 1 and a housing 2 set on the base 1. A rectangular shell 3 is fixedly set on the upper end of the housing 2. A control panel 4 is fixedly set on the side wall of the base 1. A multi-stage lifting component is set inside the housing 2. A self-adjusting component is set on the upper end of the rectangular shell 3.

[0025] The multi-stage lifting assembly includes a servo motor 5 fixedly mounted on the inner wall below the base 1, and the output end of the servo motor 5 is connected to a rotating shaft 6 for driving the lifting of the internal parts of the housing 2.

[0026] like Figure 1-4 As shown, the inner wall of the housing 2 is sequentially fitted with a first sleeve post 7, a first T-shaped post 8, a T-shaped extrusion block 9, a second T-shaped post 10, and a second sleeve post 11. The rotating shaft 6 is threadedly connected to the lower center of the first sleeve post 7. The T-shaped extrusion block 9 is rotatably connected to the protrusion on the lower inner wall of the first sleeve post 7. The inner wall of the T-shaped extrusion block 9 is threadedly connected to the first T-shaped post 8. The second T-shaped post 10 is rotatably connected to the protrusion on the lower end of the first T-shaped post 8. The outer wall of the second T-shaped post 10 is threadedly connected to the inner wall of the second sleeve post 11. The upper end of the second sleeve post 11 is fixedly connected to the top cover 12, and the rectangular shell 3 is fixedly installed on the top end of the top cover 12. The servo motor 5 can be actively started to drive the rotating shaft 6 to rotate through the control panel 4. The lifting function is realized through the coordinated rotation of the first sleeve post 7, the first T-shaped post 8, the T-shaped extrusion block 9, the second T-shaped post 10, and the second sleeve post 11, and a pre-adjustment of the mast at the upper end is performed.

[0027] To achieve automatic adjustment of mast height, such as Figure 1-4As shown, the self-adjusting assembly includes a mast 13 inserted into the upper end of a rectangular shell 3, and two connecting blocks 16 located inside the rectangular shell 3 are fixedly connected to the two sides of the mast 13 in a mirror image. Electric ceramic plates 17 are fixedly connected to the upper inner wall of the shell 2 and the upper end of the connecting blocks 16, respectively. An arc-shaped cover 14 is fixedly installed at the upper end of the mast 13. When the arc-shaped cover 14 at the upper end of the mast 13 is squeezed and moves downward, the two electric ceramic plates 17 separate and generate an electrical signal, which controls the servo motor 5 to rotate in the opposite direction and lower the height of the mast 13. Springs 18 are sleeved on the outer walls of the two electric ceramic plates 17, and the upper and lower ends of the springs 18 are fixedly connected to the rectangular shell 3 and the connecting blocks 16, respectively. After the downward squeezing force disappears, the springs 18 can retract the electric ceramic plates 17 and re-attach them.

[0028] In addition, to achieve better fixation of the mast, such as Figure 3 and Figure 4 As shown, limit rods 15 are mirror-slidably installed on both sides of the mast 13, and the lower end of the limit rods 15 is fixedly connected to the upper end of the rectangular shell 3. The mast 13, the limit rods 15 and the rectangular shell 3 form a triangular structure, which has a better stability effect.
