Description

Technical Field

[0001] This utility model relates to the field of mast technology, and in particular to a mast reinforcement mechanism. Background Technology

[0002] A mast is a vertical or near-vertical rod-shaped structure that is widely used in ships, aircraft, communication equipment, and other applications. Its core function is to support components such as sails, antennas, and signal equipment, while it may also bear the responsibilities of load-bearing and guidance.

[0003] Masts are typically made of metal, wood, or composite materials and are mounted on a carrier via fixed bases. They are used to support various functional components and require rigging to reinforce them and prevent them from tipping over.

[0004] However, when the wind force on the mast is high, the load between the mast and the reinforcement mechanism exceeds the material yield strength, and permanent deformation (such as bending or denting) will occur at the support position, resulting in a shift in the overall verticality of the mast. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art where the load exceeds the material's yield strength, causing the overall verticality of the mast to deviate, and to propose a mast reinforcement mechanism.

[0006] The technical solution of this utility model: A mast reinforcement mechanism includes a fixed base, a mast body fixedly installed on the top of the fixed base, a lower positioning sleeve sleeved on the outer wall of the mast body, and a plurality of inclined support rods fixedly installed between the lower positioning sleeve and the fixed base, and further includes:

[0007] The rigging includes a support plate, a take-up roller with an anti-drop plate is rotatably connected to the side of the support plate, a pull rope is fixedly installed on the take-up roller, an upper positioning sleeve is fitted on the outer wall of the mast body above the lower positioning sleeve, and the end of the pull rope is fixedly connected to the upper positioning sleeve.

[0008] The support plate is fixedly installed on the top of the fixed base, and the outer wall of the upper positioning sleeve is provided with an adjustment mechanism.

[0009] Optionally, the inner walls of both the lower and upper positioning sleeves are lined with a buffer rubber layer, with the lower positioning sleeve located at one-third of the height of the mast body and the upper positioning sleeve located at two-thirds of the height of the mast body.

[0010] Optionally, the fixed base adopts a cross-shaped structure, and four take-up rollers are provided, located on the top of the fixed base and near the four ends.

[0011] Optionally, the adjustment mechanism includes a rotating ring, the inner wall of which is rotatably connected to the upper positioning sleeve, an extended clearance plate fixedly installed on the outer wall of the rotating ring, a wind flag rotatably connected to the inside of the extended clearance plate via a rotating shaft, a configuration ball fixedly installed at the bottom of the wind flag, a hydraulic mechanism provided inside the upper positioning sleeve, a guide rod fixedly installed on the side of the configuration ball facing the upper positioning sleeve, and the hydraulic mechanism located at the end of the guide rod.

[0012] Optionally, the hydraulic mechanism includes a first arc plate, which is fixedly installed at the end of the guide rod. A manual hydraulic pump is fixedly installed inside the upper positioning sleeve. The end of the manual hydraulic pump is fixedly connected to a second arc plate, which is located on the moving path of the first arc plate.

[0013] Optionally, a hydraulic motor is fixedly installed on the side of the support plate, the shaft of the hydraulic motor is fixedly connected to the take-up roller, and a hydraulic pipe is fixedly installed between the manual hydraulic pump and the hydraulic motor.

[0014] Optionally, a protective box is fixedly installed at the bottom of the extended clearance plate, and the outer wall of the guide rod is slidably connected to the protective box.

[0015] Optionally, the top of the fixed base is provided with a groove, and the mast body is fixedly installed in the groove of the fixed base.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] This invention uses a winding roller and a pull rope to apply tension to the upper positioning sleeve from four directions to support and fix the position of the mast body. The addition of the upper positioning sleeve positions it at two-thirds of the height of the mast body. The load that was originally concentrated near the bottom of the mast body is distributed to the upper positioning sleeve. The lower and upper positioning sleeves share the load, which greatly reduces bending moment and shear force, and avoids excessive local stress that could cause the mast body to bend.

[0018] Furthermore, the wind force is used to deflect the wind flag, which in turn causes the configuration ball to push the first arc plate. The first arc plate, through the second arc plate, drives the manual hydraulic pump to allow hydraulic oil to enter the hydraulic motor, thereby causing the winding roller at the corresponding position to rotate. This increases the tension of the pull rope on the upper positioning sleeve at that position, thus counteracting the force of the wind on the mast body and improving the stability of the mast body.

[0029] Example 1

[0030] This embodiment proposes a mast reinforcement mechanism, such as... Figure 1 As shown, the system includes a fixed base 1, a mast body 2 fixedly mounted on the top of the fixed base 1, a lower positioning sleeve 4 fitted onto the outer wall of the mast body 2, and multiple inclined support rods 3 fixedly mounted between the lower positioning sleeve 4 and the fixed base 1. A groove is formed in the top of the fixed base 1, and the mast body 2 is fixedly installed within the groove. The lower half of the mast body 2 is supported by the support rods 3 and the lower positioning sleeve 4.

[0031] like Figure 2 and Figure 3 As shown, a rigging 5 is provided on the outer wall of the mast body 2. The rigging 5 includes a support plate 51, and a winding roller 52 with an anti-fall plate is rotatably connected to the side of the support plate 51. A pull rope 53 is fixedly installed on the winding roller 52. An upper positioning sleeve 54 is fitted on the outer wall of the mast body 2 above the lower positioning sleeve 4. The end of the pull rope 53 is fixedly connected to the upper positioning sleeve 54. The fixed base 1 adopts a cross-shaped structure, and four winding rollers 52 are provided, respectively located on the top of the fixed base 1 and near the four ends. The pull rope 53 applies tension to the upper positioning sleeve 54 from four directions from the winding rollers 52 to support and fix the position of the mast body 2 and prevent the mast body 2 from tilting.

[0032] The inner walls of both the lower positioning sleeve 4 and the upper positioning sleeve 54 are lined with a buffer rubber layer, which reduces the pressure between the mast body 2 and the lower positioning sleeve 4 and the upper positioning sleeve 54. The lower positioning sleeve 4 is located at one-third of the height of the mast body 2, and the upper positioning sleeve 54 is located at two-thirds of the height of the mast body 2, increasing the stress-bearing area.

[0033] In this embodiment, the upper positioning sleeve 54 is pulled from four directions by the winding roller 52 using the pull rope 53 to support and fix the position of the mast body 2. The upper positioning sleeve 54 is added so that it is located at two-thirds of the height of the mast body 2. The load that was originally concentrated near the bottom of the mast body 2 is distributed to the upper positioning sleeve 54. The lower positioning sleeve 4 and the upper positioning sleeve 54 share the force, which greatly reduces the bending moment and shear force, and avoids excessive local stress, which would cause the mast body 2 to bend.

[0034] Example 2

[0035] Based on Embodiment 1, this embodiment proposes a mast reinforcement mechanism, such as... Figure 3 and Figure 4As shown, the outer wall of the upper positioning sleeve 54 is provided with an adjustment mechanism 6. The adjustment mechanism 6 includes a rotating ring 61. The inner wall of the rotating ring 61 is rotatably connected to the upper positioning sleeve 54. An extended clearance plate 62 is fixedly installed on the outer wall of the rotating ring 61. A wind flag 63 is rotatably connected to the inside of the extended clearance plate 62 through a rotating shaft. A configuration ball 64 is fixedly installed at the bottom of the wind flag 63. A hydraulic mechanism is provided inside the upper positioning sleeve 54. A guide rod is fixedly installed on the side of the configuration ball 64 facing the upper positioning sleeve 54. The hydraulic mechanism is located at the end of the guide rod.

[0036] Under the action of wind, the wind flag 63 rotates the rotating ring 61, extending the avoidance plate 62 to be parallel to the wind direction. At the same time, the wind flag 63 tilts under the action of wind, and the wind flag 63 uses the configured ball 64 to squeeze the hydraulic mechanism.

[0037] The hydraulic mechanism includes a manual hydraulic pump 67, which is fixedly installed inside the upper positioning sleeve 54. The end of the manual hydraulic pump 67 is fixedly connected to the second arc plate 66. A hydraulic motor 68 is fixedly installed on the side of the support plate 51. The shaft of the hydraulic motor 68 is fixedly connected to the take-up roller 52. A hydraulic pipe is fixedly installed between the manual hydraulic pump 67 and the hydraulic motor 68. A protective box is fixedly installed at the bottom of the extended clearance plate 62. A guide rod is slidably connected to the inner wall of the protective box. A first arc plate 65 is fixedly installed at the end of the guide rod. The second arc plate 66 is located on the moving path of the first arc plate 65.

[0038] The wind flag 63 deflects the ball 64 and pushes the first arc plate 65 with the guide rod. The first arc plate 65 then pushes the manual hydraulic pump 67 with the second arc plate 66 to allow hydraulic oil to enter the hydraulic motor 68, thereby rotating the take-up roller 52 at the corresponding position to increase the tension of the pull rope 53 on the upper positioning sleeve 54 at that position.

[0039] In this embodiment, the wind force is used to deflect the wind flag 63, and the wind flag 63 causes the configuration ball 64 to push the first arc plate 65. The first arc plate 65 uses the second arc plate 66 to drive the manual hydraulic pump 67 to allow hydraulic oil to enter the hydraulic motor 68, thereby causing the winding roller 52 at the corresponding position to rotate, so as to increase the tension of the pull rope 53 at that position on the upper positioning sleeve 54, so as to counteract the force of the wind on the mast body 2 and improve the stability of the mast body 2.

[0040] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
