Description

Technical Field

[0001] This utility model relates to the field of torque-shear bolt technology, specifically to a large-span torque-shear bolt assembly. Background Technology

[0002] Torque-shear bolts are fasteners specifically designed for high-strength connections. They are highly practical in applications, especially in steel structure projects requiring stable connections.

[0003] After the existing large-span torsion shear bolt assemblies are installed, workers usually need to manually apply rust remover to the torsion shear bolts, which reduces the labor intensity of the workers.

[0004] To address these issues, this invention provides a large-span torsion-shear bolt assembly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a large-span torsion-shear bolt assembly, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a large-span torsion shear bolt assembly, including a torsion shear bolt, one end of which is movably connected to a spline head, a washer movably connected to the side wall of the torsion shear bolt, a preservative storage bag fixedly connected to one side of the washer, a torsion shear nut threadedly connected to the torsion shear bolt, a breaking rod fixedly connected to one side of the torsion shear nut, and a side of the torsion shear nut movably connected to a side of the preservative storage bag.

[0007] Preferably, a magnet ring is fixedly connected to the side wall of the gasket, and the longitudinal section of the magnet ring is rectangular.

[0008] Preferably, a sealing steel ring is movably connected to one side of the magnet ring, and the inner wall of the sealing steel ring is movably connected to the side wall of the preservative storage bag.

[0009] Preferably, the preservative storage bag has a groove on the other side, and a pressure sensor is fixedly connected to one side of the gasket.

[0010] Preferably, a limiting groove is provided on one side of the gasket, and the longitudinal section of the breaking rod is conical.

[0011] Preferably, the torque shear bolt has a fixing groove inside, an electric push rod is fixedly connected to the inner wall of the fixing groove, a protective plate is fixedly connected to one end of the electric push rod, and the side wall of the protective plate is slidably connected to the inner wall of the electric push rod.

[0012] Beneficial effects

[0013] This utility model provides a large-span torsion-shear type bolt assembly. Compared with the prior art, it has the following advantages:

[0014] (1) When equipment needs to be fixed with torque shear bolts, the staff inserts the torque shear bolts into the threaded holes of the equipment. After the staff places the washer on the side wall of the torque shear bolt, the staff manually places the torque shear nut on the side wall of the torque shear bolt to give it a warning. The staff tightens the torque shear nut with an electric wrench. When the torque shear nut is tightened, the torque shear nut moves towards the side of the washer. The torque shear nut drives the crushing rod to approach the side of the washer. When the torque shear nut moves to the side of the corrosion inhibitor storage bag, the crushing rod punctures the corrosion inhibitor storage bag. The rust inhibitor inside the corrosion inhibitor storage bag is sprayed out to apply rust inhibitor between the washer and the torque shear nut, so as to prevent the torque shear bolt and the torque shear nut from rusting and being damaged over time.

[0015] (2) When the pressure sensor detects that the torsion shear nut has been tightened, the sprite head will be unscrewed by the electric wrench. The pressure sensor controls the electric push rod to start, the electric push rod extends, and the electric push rod drives the protective plate to move out of the torsion shear bolt. The protective plate protects the break between the torsion shear bolt and the sprite head, preventing workers from being scratched by the break between the torsion shear bolt and the sprite head.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please see Figure 1 - Figure 3 A large-span torsion shear bolt assembly includes a torsion shear bolt 1, a sprite head 2 movably connected to one end of the torsion shear bolt 1, a washer 3 movably connected to the side wall of the torsion shear bolt 1, a preservative storage bag 6 fixedly connected to one side of the washer 3, a torsion shear nut 10 threadedly connected to the torsion shear bolt 1, a breaking rod 11 fixedly connected to one side of the torsion shear nut 10, and a side of the torsion shear nut 10 movably connected to one side of the preservative storage bag 6.

[0023] It should be noted that when equipment needs to be fixed using torque shear bolt 1, the operator inserts torque shear bolt 1 into the threaded hole of the equipment. After placing washer 3 on the side wall of torque shear bolt 1, the operator manually places torque shear nut 10 on the side wall of torque shear bolt 1 as a warning. The operator then tightens torque shear nut 10 using an electric wrench. When torque shear nut 10 is tightened, it moves towards washer 3. Torque shear nut 10 moves crushing rod 11 closer to washer 3. When torque shear nut 10 moves to the side of corrosion inhibitor storage bag 6, crushing rod 11 punctures corrosion inhibitor storage bag 6, and the rust inhibitor inside corrosion inhibitor storage bag 6 is sprayed out to coat the space between washer 3 and torque shear nut 10 with rust inhibitor, preventing torque shear bolt 1 and torque shear nut 10 from rusting and being damaged over time.

[0024] In an optional embodiment: a magnet ring 4 is fixedly connected to the side wall of the gasket 3, and the longitudinal section of the magnet ring 4 is rectangular.

[0025] It should be noted that the magnetic ring 4 can fix the gasket 3 to one side of the equipment, preventing the gasket 3 from sliding during the tightening of the torsion shear nut 10.

[0026] In an optional embodiment: a sealing steel ring 5 is movably connected to one side of the magnet ring 4, and the inner wall of the sealing steel ring 5 is movably connected to the side wall of the preservative storage bag 6.

[0027] It should be noted that the sealing steel ring 5 can limit the rust remover inside the corrosion inhibitor storage bag 6, preventing the rust remover from spraying everywhere. At the same time, it can protect the torsion shear nut 10 from rainwater impacting its surface.

[0028] In an optional embodiment: a groove 9 is provided on the other side of the preservative storage bag 6, and a pressure sensor 7 is fixedly connected to one side of the gasket 3.

[0029] It should be noted that the tightness of the torque shear nut 10 can be detected by setting the pressure sensor 7. When the torque shear nut 10 moves to the side of the pressure sensor 7, the pressure sensor 7 will sense the pressure and remind the staff that the torque shear nut 10 has been tightened. Otherwise, it means that the torque shear nut 10 still needs to be tightened, and the staff does not need to check the tightness of the torque shear nut 10 afterward.

[0030] In an optional embodiment: a limiting groove 8 is provided on one side of the gasket 3, and the longitudinal section of the breaking rod 11 is tapered.

[0031] It should be noted that the conical crushing rod 11 makes it more convenient for the crushing rod 11 to break the preservative storage bag 6.

[0032] In an optional embodiment: a fixing groove 12 is provided inside the torque shear bolt 1, an electric push rod 13 is fixedly connected to the inner wall of the fixing groove 12, a protective plate 14 is fixedly connected to one end of the electric push rod 13, and the side wall of the protective plate 14 is slidably connected to the inner wall of the electric push rod 13.

[0033] It should be noted that when the pressure sensor 7 detects that the torque shear nut 10 has been tightened, the sprite head 2 will be unscrewed by the electric wrench. The pressure sensor 7 controls the electric push rod 13 to start, the electric push rod 13 extends, and the electric push rod 13 drives the protective plate 14 to move out of the torque shear bolt 1. The protective plate 14 protects the break between the torque shear bolt 1 and the sprite head 2, preventing workers from being scratched by the break between the torque shear bolt 1 and the sprite head 2.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, when equipment needs to be fixed using a torque shear bolt 1, the operator inserts the torque shear bolt 1 into the threaded hole of the equipment. After placing a washer 3 on the side wall of the torque shear bolt 1, the operator manually places a torque shear nut 10 on the side wall of the torque shear bolt 1 as a warning. The operator then tightens the torque shear nut 10 using an electric wrench. When the torque shear nut 10 is tightened, it moves towards the washer 3. The torque shear nut 10 moves the crushing rod 11 closer to the washer 3. When the torque shear nut 10 moves to the side of the corrosion inhibitor storage bag 6, the crushing rod 11 punctures the corrosion inhibitor storage bag 6, and the rust inhibitor inside the corrosion inhibitor storage bag 6 is sprayed out to coat the space between the washer 3 and the torque shear nut 10 with rust inhibitor, preventing the torque shear bolt 1 and the torque shear nut 10 from rusting and being damaged over time.

[0036] The magnetic ring 4 can be used to fix the gasket 3 to one side of the equipment, preventing the gasket 3 from sliding during the tightening of the torsion shear nut 10;

[0037] The sealing steel ring 5 can limit the rust remover inside the corrosion inhibitor storage bag 6, preventing the rust remover from spraying everywhere. At the same time, it can protect the torsion shear nut 10 from direct impact of rainwater on the surface of the torsion shear nut 10.

[0038] The tightness of the torque shear nut 10 can be detected by setting the pressure sensor 7. When the torque shear nut 10 moves to the side of the pressure sensor 7, the pressure sensor 7 will feel the pressure and remind the staff that the torque shear nut 10 has been tightened. Otherwise, it means that the torque shear nut 10 still needs to be tightened, and the staff does not need to check the tightness of the torque shear nut 10 afterward.

[0039] The conical crushing rod 11 makes it easier to break the preservative storage bag 6.

[0040] When the pressure sensor 7 detects that the torque shear nut 10 has been tightened, the sprite head 2 will be unscrewed by the electric wrench. The pressure sensor 7 controls the electric push rod 13 to start, the electric push rod 13 extends, and the electric push rod 13 drives the protective plate 14 to move out of the torque shear bolt 1. The protective plate 14 protects the break between the torque shear bolt 1 and the sprite head 2, preventing workers from being scratched by the break between the torque shear bolt 1 and the sprite head 2.
