Description

Technical Field

[0001] The utility model relates to the technical field of mast structures, in particular to a high-stability ship mast structure. Background Art

[0002] A ship is a man-made means of transportation that mainly operates in geographical waters. A mast refers to a tall pole on a ship that hangs sails and flags, installs antennas, and supports an observation platform. It is a long wooden pole or metal pole that is usually erected vertically from the keel or centerboard of the ship and can support the lower girders of the horizontal sails, the booms or the diagonal girders. The mast on a ship has many uses, such as using it to install signal lights, hang flags, and set up telegraph antennas; in addition, it can also support the cargo boom, and hoist and unload cargo; the mast of a ship originated from the sailing era. While setting sail, it also plays the role of the "eyes and ears" of the ship. The right way is: "At three o'clock in the morning, the wind is strong and the flags are in chaos." With the progress of society and the development of ship technology, the mast of the sailing era gradually lost its function as a power source pillar and evolved into a pure carrier of ship information sources, especially with the emergence of radar. However, the towering bridge that served as a platform in the early days is no longer popular in the post-giant warship and cannon era. The relatively low and smooth bridge obviously cannot meet the requirements of "standing high and looking far". Therefore, the changes in the mast structure have been closely related to the advancement of radar technology. From thin to thick, from column to tower, the mast has become the iconic structure of the ship's "rows of ships towering like buildings", and has also completed a spiral upward trajectory of change without anyone noticing.

[0003] The masts of modern ships can be roughly divided into lattice masts, tower masts and barrel masts according to their different structural forms. Although the tower mast has better performance in terms of load-bearing capacity, structural strength, and vibration fatigue resistance, it is heavy and increases the weight of the ship. Although the lattice mast and barrel mast have a small weight, their load-bearing capacity is small and their strength is low. Utility Model Content

[0004] The main purpose of the utility model is to provide a high-stability ship mast structure to solve the problems of increased ship load, small carrying capacity and low strength proposed in the relevant technology.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a high-stability ship mast structure is provided, including a mast body, wherein the mast body includes three main poles, the bottoms of the main poles are arranged in an equilateral triangle, the tops of the main poles are respectively inclined toward the center points of the triangles and are fixedly connected to each other, a plurality of horizontal poles are provided between the main poles in the vertical direction, the two ends of the horizontal poles are respectively fixedly connected to the main poles, and the horizontal poles at the same height form an equilateral triangle, and the two main poles are divided into a plurality of trapezoids by the horizontal poles, each trapezoid is provided with a diagonal brace along the diagonal, the two ends of the diagonal brace are respectively fixedly connected to the main poles, the diagonal braces on the same surface of the mast body are arranged in the same direction, and the main poles, horizontal poles and diagonal braces are all hollow poles.

[0006] Furthermore, a base is provided below the mast body, and the base is fixedly connected to the mast body.

[0007] Furthermore, the base includes a base plate, and a plurality of bolt holes are provided on the base plate. The bolt holes penetrate the base plate, and the bolt holes are arranged in an equilateral triangle.

[0008] Furthermore, a pad is provided under the base plate, the pad is movably connected to the base plate, a pad hole is provided on the pad, and the pad hole passes through the pad.

[0009] Furthermore, the pad is provided with three pad holes, the pad holes are arranged in an equilateral triangle, and the pad holes correspond to the bolt holes respectively.

[0010] Furthermore, a bolt is provided in the bolt hole, and the bolt is threadedly connected to the bolt hole.

[0011] Furthermore, the mast body comprises three surfaces, and the three surfaces of the mast body are all the same.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the mast body is provided with three main poles, and the inclined main poles decompose the gravity it receives into vertical downward pressure and horizontal thrust. The main poles offset the vertical downward pressure with their own strength. Several horizontal poles are evenly distributed between the main poles in the horizontal direction. The tension between the horizontal poles and the main poles offsets the horizontal thrust, so that the entire mast body is in an internal force balance state. The diagonal rods divide the trapezoidal units of each surface into two triangles. The stability of the triangle allows the various components of the mast body to be more firmly combined together. The main poles, horizontal poles and diagonal rods are all hollow poles, which reduces the dead weight of the mast body. The mast body adopts a cylindrical component with a small wind receiving area and a simple structure. Most of the crosswind on the sea surface passes through the gaps in the mast body, and the wind force acting on the mast body is small. While occupying the highest position of the ship, the mast body has little effect on the stability of the hull, so that the mast body has the advantages of light dead weight, large bearing capacity and high strength.

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] See also Figures 1 to 6The present embodiment provides a high-stability ship mast structure, including a mast body 1, wherein the mast body 1 includes three main poles 101, the bottoms of the main poles 101 are arranged in an equilateral triangle to enhance the stability of the mast body 1, the tops of the main poles 101 are respectively inclined toward the center point of the triangle, and are fixedly connected to each other, so that the mast body 1 stands in the ship in a triangular cone shape, and a plurality of horizontal poles 102 are arranged between the main poles 101 in the vertical direction, and the two ends of the horizontal poles 102 are respectively fixedly connected to the main poles 101, and the horizontal poles 102 connect the two main poles 101 together, and the horizontal poles at the same height 102 forms an equilateral triangle to enhance the stability of the mast body 1. The two main poles 101 are divided into several trapezoids by the horizontal pole 102. Each trapezoid is provided with a diagonal rod 103 along the diagonal line. Both ends of the diagonal rod 103 are fixedly connected to the main poles 101 respectively. The diagonal rods 103 on the same surface of the mast body 1 are arranged in the same direction. The diagonal rods 103 divide the trapezoidal units on each surface into two triangles. The stability of the triangle allows the various components of the mast body 1 to be more firmly combined together. The main poles 101, the horizontal poles 102 and the diagonal rods 103 are all hollow poles, which reduces the deadweight of the mast body 1.

[0024] A base 2 is provided below the mast body 1 , and the base 2 is fixedly connected to the mast body 1 . The mast body 1 is fixed on the base 2 to keep the mast body 1 in a vertical state.

[0025] The base 2 includes a base plate 201, on which a plurality of bolt holes 202 are provided. The bolt holes 202 penetrate the base plate 201, allowing bolts 204 to pass through the base plate 201 to fix the base 2 on the ship. The bolt holes 202 are arranged in an equilateral triangle, so that the base plate 201 is subjected to balanced force and is not easily damaged.

[0026] A pad 203 is provided under the base plate 201, and the pad 203 is movably connected to the base plate 201. A pad hole 2031 is provided on the pad 203, and the pad hole 2031 penetrates the pad 203. The bolt 204 passes through the pad hole 2031 and enters the bolt hole 202. The pad 203 bears the pressure of the bolt 204. Since the area of ​​the pad 203 is larger than that of the bolt 204, the pressure on the pad 203 is reduced, thereby protecting the pad 203 from being damaged.

[0027] The backing plate 203 is provided with three backing plate holes 2031 , which are arranged in an equilateral triangle and correspond to the bolt holes 202 respectively, so that the backing plate 203 is subjected to balanced force and is not easily damaged.

[0028] A bolt 204 is provided in the bolt hole 202 , and the bolt 204 is threadedly connected to the bolt hole 202 . The bolt 204 is screwed into the bolt hole 202 to fix the base 2 on the ship.

[0029] The mast body 1 comprises three surfaces, and the three surfaces of the mast body 1 are all identical, so that the forces on the surfaces of the mast body 1 are the same, and stress concentration will not occur to damage the mast body 1.

[0030] Transport the mast to the ship, unscrew the bolt 204 from the bolt hole 202 in a counterclockwise direction, remove the bolt 204 and the pad 203 in turn, move the base 2, align the bolt hole 202 on the base 2 with the hole on the ship's keel, place the pad 203 under the keel, align the pad hole 2031 with the keel hole, insert the bolt 204 from the pad hole 2031 into the bolt hole 202 from under the pad 203, and twist it in a clockwise direction to screw the bolt 204 into the bolt hole 202 of the base plate 201 and tighten it. Three bolts 204 are distributed on one pad 203, and the three bolts 204 are arranged in an equilateral triangle, so that the pad 203 is evenly stressed and not easily damaged. Several pads 203 and bolts 204 are evenly distributed on the bottom edge of the base plate 201 to enhance the bite force between the base plate 201 and the ship's keel, and the mast body 1 is firmly fixed to the ship. When a radar or other object is loaded on the top of the mast body 1, the gravity of the object is applied downward to the main rod 101. The inclined main rod 101 decomposes the gravity it receives into vertical downward pressure and horizontal thrust. The main rod 101 offsets the vertical downward pressure with its own strength. A number of horizontal rods 102 are evenly distributed in the horizontal direction between the main rods 101. The tension between the horizontal rods 102 and the main rods 101 offsets the horizontal thrust, so that the entire mast body 1 is in an internal force balance state. The inclined rods 103 divide the trapezoidal units on each surface into Two triangles, the stability of the triangle allows the various components of the mast body 1 to be more firmly combined together. The main rod 101, the horizontal rod 102 and the diagonal rod 103 are all hollow rods, which reduces the deadweight of the mast body 1. The mast body 1 adopts a cylindrical component with a small wind receiving area and a simple structure. Most of the crosswind on the sea surface passes through the gaps in the mast body 1, and the wind force acting on the mast body 1 is small. While the mast body 1 occupies the highest position of the ship, it has little effect on the stability of the hull, so that the mast body 1 has the advantages of light weight, large bearing capacity and high strength.
