Description

Technical Field

[0001] The present invention relates to the technical field of bolts, in particular to a bolt with high tensile strength and high toughness for high-voltage power transmission and transformation. Background Art

[0002] In the field of high-voltage power transmission and transformation, bolts are key components for connection and fixation, and their performance is directly related to the safety and stability of the entire transmission and transformation system. With the continuous development of the power industry, the performance requirements for bolts are becoming increasingly stringent, especially in terms of tensile strength, toughness, and loosening resistance. Bolts are manufactured using special materials and processes, achieving high tensile strength and toughness. They are able to effectively resist deformation and fracture when subjected to high tensile forces, ensuring the safe operation of high-voltage power transmission and transformation equipment under various complex operating conditions and improving the reliability of the entire transmission and transformation system.

[0003] Conventional bolts used in high-voltage power transmission and transformation present numerous practical challenges. Because high-voltage substation equipment operates in complex environments for extended periods, subject to vibration, temperature fluctuations, and other factors, bolts are prone to loosening. Once loosened, this not only impacts the normal operation of the equipment but can also cause serious safety incidents.

[0004] Furthermore, long-term friction between the screw and the hole in the equipment can easily lead to rust, affecting its service life and connection performance. Furthermore, the use and storage of lubricating oil is also a challenge. If the lubricating oil is directly exposed to the outside, it is prone to volatilization and loss, and cannot effectively lubricate it. Summary of the Invention

[0005] The object of the present invention is to provide a high-tensile-resistance, high-toughness bolt for high-voltage power transmission and transformation, so as to solve the problems raised in the above-mentioned background technology.

When the elastic support plate is in the initial state, the elastic support plate supports the pressure ring to extend out of the reserved groove.

The structure utilizes a handle, rubber ball, and slot to allow simultaneous rotation of nuts one and two, preventing them from independently deflecting and loosening. Furthermore, the interaction of a pressure ring, clamping block, and rubber ring three creates a clamping stop between nut one and the screw rod, further enhancing the anti-loosening effect and ensuring long-term, stable connection of the bolt on high-voltage power transmission and transformation equipment. An oil reservoir is located at one end of the screw rod. Through the synergistic action of oil-absorbing cotton pad one, an oil-absorbing cotton core, and oil-absorbing cotton pad two, lubricating oil slowly seeps between the screw rod and the equipment hole, effectively lubricating the screw and hole, reducing friction, and preventing rust on the screw rod body. Furthermore, oil-absorbing cotton pad three seals one side of the hole, reducing oil outflow from the hole, extending the lubricating oil's service life, and ensuring the long-lasting lubrication effect.

DETAILED DESCRIPTION

[0033] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention.

[0034] See also Figures 1 to 12The present invention provides a technical solution: a high-tensile-strength and high-toughness bolt for high-voltage power transmission and transformation, comprising a screw rod 1. The screw rod 1 is manufactured as a whole using special materials and processes, and has high tensile strength and toughness. When subjected to large tensile force, it can effectively resist deformation and fracture, ensure the safe operation of high-voltage power transmission and transformation equipment under various complex working conditions, and improve the reliability of the entire power transmission and transformation system; the rod body of the screw rod 1 is threaded with a nut 1 2 and a nut 2 3, and a connecting plate 4 is fixed to the end of the nut 2 3 close to the nut 1 2, the connecting plate 4 is a circular ring plate, and the inner ring opening of the connecting plate 4 is a truncated cone opening, and a plug ring 5 is inserted into the inner ring opening of the connecting plate 4, the plug ring 5 is a truncated cone ring plate, the plug ring 5 is fixed to the other end of the nut 1 2, and after the connecting plate 4 is clamped between the nut 1 2 and the nut 2 3, the plug ring 5 is inserted into the inner ring opening of the connecting plate 4; a rubber ring 2 7 is fixed to the inner ring opening of the plug ring 5, and the rubber ring 2 7 is clamped between the plug ring 5 and the screw rod 1, and a rubber ring 6 is fixed on the outer ring surface of the plug ring 5, and the rubber ring 6 is clamped between the plug ring 5 and the connecting plate 4. After the rod body of the screw rod 1 passes through the hole on the surface of the high-voltage substation equipment, nut 1 2 and nut 2 3 are sequentially sleeved and screwed on the rod body of the screw rod 1. After nut 1 2 is locked on the rod body of the screw rod 1, one side of nut 1 2 is tightly against the surface of the equipment, and rubber ring 2 7 is clamped between the plug ring 5 and the screw rod 1 to prevent the screw connection between nut 1 2 and screw 1 from loosening. When nut 2 3 and screw 1 are screwed and locked, the plug ring 5 is inserted into the inner ring mouth of the connecting plate 4, and the rubber ring 1 6 is clamped between the plug ring 5 and the connecting plate 4 to increase the friction between the connecting plate 4 and the plug ring 5. Nut 1 2 and nut 2 3 cooperate to prevent the screw rod 1 from falling off from the hole.

[0035] Two embedding grooves 17 are provided on the surface of the connecting plate 4, and the two embedding grooves 17 are symmetrically distributed about the inner ring mouth of the connecting plate 4. The other end of the nut 3 is provided with an embedding groove 28, and the surface of the embedding groove 28 is provided with a socket 19. The embedding groove 17, the embedding groove 28 and the socket 19 are connected. A handle 20 is inserted into the inside of the socket 19, and a rubber ball 22 is fixed on one end of the handle 20. The rubber ball 22 is inserted into the slot 21. The slot 21 is provided at the other end of the nut 2. The slot 21 is a circular groove with a circular fracture. A pull ring 23 is fixed to the other end of the handle 20. After the plug ring 5 is inserted into the inner ring opening of the connecting plate 4, the plug handle 20 is squeezed and pushed. After the top of the plug handle 20 is pushed into the card slot 21, the rubber ball 22 is stuck in the card slot 21. In this way, a connection is set between the nut 1 2 and the nut 2 3, so that the nut 1 2 and the nut 2 3 can rotate synchronously, thereby avoiding the phenomenon that the nut 1 2 and the nut 2 3 deflect and loosen individually; when canceling the connection, pinch the pull ring 23 by hand to pull the plug handle 20 out of the card slot 21.

[0036] A reserved groove 8 is provided at one end of the nut 2, and a clamping block 11 is inserted on the side wall of the reserved groove 8. A rubber ring 3 10 is fixed to the inner ring surface of the nut 2, and one end of the clamping block 11 is fixed to the outer ring surface of the rubber ring 3 10. The reserved groove 8 is a hexagonal annular groove, and two parallel side walls of the reserved groove 8 are provided with sockets 9. The clamping block 11 and the sockets 9 correspond one to one. The clamping block 11 is inserted into the sockets 9, and the end of the clamping block 11 extending to the reserved groove 8 is provided with an inclined surface on the top surface. A pressure ring 12 is inserted into the inside of the reserved groove 8, and the rubber ring 3 10 is clamped between the screw 1 and the nut 2. After the pressure ring 12 falls into the reserved groove 8, the pressure ring 12 squeezes The clamping block 11 and the rubber ring 3 10 are tightly clamped between the clamping block 11 and the screw 1; a notch 13 is provided at one end of the pressure ring 12, and the notch 13 is a hexagonal annular groove. A rubber support ring 14 is fixed inside the notch 13, and one end of the rubber support ring 14 is fixed to the surface of the reserved groove 8, and a rubber pad 16 is fixed to the other end of the pressure ring 12; an elastic support piece 15 is fixed to the outer wall of the pressure ring 12, and the bottom end of the elastic support piece 15 is fixed to the outer ring surface of the nut 1 2. When the elastic support piece 15 is in the initial state, the elastic support piece 15 supports the pressure ring 12 to extend out of the reserved groove 8. After the pressure ring 12 falls into the reserved groove 8, the elastic support piece 15 is compressed and elastically deformed. When nut 12 is screwed onto screw rod 1 and advanced, elastic support piece 15 contacts the surface of the equipment. As nut 12 continues to advance, pressure ring 12 is squeezed into the reserved groove 8. Rubber support ring 14 and elastic support piece 15 are deformed under pressure. In the process of pressure ring 12 retracting into the reserved groove 8, pressure ring 12 squeezes clamping block 11 along the inclined surface, and clamping block 11 squeezes rubber ring 3 10, thereby forming a clamping limit between nut 12 and screw rod 1, thereby preventing nut 12 from loosening on screw rod 1. The resilience of elastic support piece 15, pressure ring 12 and rubber pad 16 makes nut 12 and screw rod 1 tightly screwed together. After nut 2 3 and nut 12 are connected by plug handle 20, they rotate synchronously. In this way, nut 2 3 is also restricted, thereby strengthening the connection firmness of nut 12 and nut 2 3 on screw rod 1.

[0037] An oil storage tank 24 is provided at one end of the screw 1 for storing lubricating oil. An oil seepage hole 29 is provided on the surface of the oil storage tank 24. An oil-absorbing cotton piece 34 is embedded at one end of the nut 2. A cover 25 is connected to one end of the oil storage tank 24. The cover 25 is fixed to the end of the screw 1. An oil filling hole 26 is provided on the surface of the cover 25. A rubber block 27 is fixed inside the oil filling hole 26. An oil seepage tank 28 is provided on the surface of the end plate of the screw 1. The oil seepage tank 28 is an annular groove. A plurality of oil seepage holes 29 are provided. The plurality of oil seepage holes 29 are arranged in a circle. The rod body is distributed in a circle with the center axis, and the oil seepage groove 28 and the oil seepage hole 29 are connected; an oil-absorbing cotton piece 2 31 is fixed inside the oil seepage groove 28, an oil-absorbing cotton piece 1 30 is fixed inside the oil storage tank 24, an oil-absorbing cotton core 32 is fixed between the oil-absorbing cotton piece 1 30 and the oil-absorbing cotton piece 2 31, and the oil-absorbing cotton core 32 passes through the oil seepage hole 29, and a release paper is bonded to the surface of the screw 1, and the release paper covers the oil-absorbing cotton piece 2 31; an embedding groove 33 is opened at one end of the nut 1 2, and an oil-absorbing cotton piece 34 is fixed inside the embedding groove 33. After sucking the lubricating oil in advance with the help of a needle, the needle is passed through the rubber block 27, the lubricating oil is injected into the oil storage tank 24, and the needle is removed; when the screw 1 is not installed and used, a release paper is set on one side of the oil-absorbing cotton sheet 2 31 for covering. When the screw 1 is installed and used, the release paper is torn off. After the screw 1 and the nut 1 2 are screwed to the equipment, the lubricating oil inside the oil storage tank 24 will soak into the oil-absorbing cotton sheet 1 30, the oil-absorbing cotton core 32 and the oil-absorbing cotton sheet 2 31 and then seep into the hole. The lubricating oil lubricates the screw 1 and the hole to prevent the rod body of the screw 1 from rusting, and the oil-absorbing cotton sheet 3 34 is sealed on one side of the hole to reduce the outflow of lubricating oil from the hole.

[0038] How to use the high-tensile strength, high-toughness, high-voltage power transmission and transformation bolts: Use a needle to suck out the lubricating oil, insert the needle through the rubber block 27 on the surface of the cover 25, and inject the lubricating oil into the oil storage tank 24 at one end of the screw 1, then remove the needle. When the screw 1 is not installed and used, set release paper on one side of the oil-absorbing cotton sheet 2 31 in the oil seepage tank 28 for covering. Insert the rod body of the screw 1 through the hole on the surface of the high-voltage substation equipment. Sleeve the nut 2 onto the rod body of the screw 1, and rotate the nut 2 to screw it onto the screw 1 and push it forward. During the advancement process, the elastic support piece 15 will contact the surface of the equipment. As the nut 2 continues to advance, the pressure ring 12 is squeezed into the reserved groove 8, and the rubber support ring 14 and the elastic support piece 15 are deformed under pressure. As the pressure ring 12 retracts into the reserved groove 8, the pressure ring 12 squeezes the clamping block 11 along the inclined surface of the top surface of the clamping block 11, and the clamping block 11 squeezes the rubber ring 3 10, so that the rubber ring 3 10 is tightly clamped between the clamping block 11 and the screw 1, thereby forming a clamping limit between the nut 1 2 and the screw 1. At the same time, the resilience of the elastic support piece 15, the pressure ring 12, and the rubber pad 16 makes the nut 1 2 and the screw 1 tightly screwed together. After the rod body of the screw 1 is locked, one side of the nut 1 2 is tightly pressed against the surface of the equipment, and the rubber ring 2 7 is clamped between the plug ring 5 and the screw 1 to prevent the screw connection between the nut 1 2 and the screw 1 from loosening. Sleeve the nut 2 3 onto the rod body of the screw 1, and rotate the nut 2 3 to make it close to the nut 1 2. After nut 2 (3) and screw 1 are screwed together and locked, insert ring 5 into the inner ring opening of connecting plate 4. Rubber ring 1 (6) is clamped between ring 5 and connecting plate 4, increasing friction between connecting plate 4 and ring 5. After inserting ring 5 into the inner ring opening of connecting plate 4, push handle 20, pushing the top of handle 20 into slot 21, so that rubber ball 22 is locked in slot 21. This establishes a connection between nut 1 (2) and nut 2 (3), allowing them to rotate synchronously and preventing individual deflection and loosening. Remove the release paper from oil-absorbing cotton sheet 2 (31) in oil seepage groove 28 at the end of screw 1. The lubricating oil in oil reservoir 24 will soak through oil-absorbing cotton sheet 1 (30), oil-absorbing cotton core 32, and oil-absorbing cotton sheet 2 (31) and then seep into the hole, lubricating screw 1 and the hole, preventing rust on the screw body. At the same time, the oil-absorbing cotton sheet 34 is sealed on one side of the hole to reduce the outflow of lubricating oil from the hole.

[0039] To disassemble, undo the connection between nut 1 2 and nut 2 3: pinch the pull ring 23 and pull the insert handle 20 to disengage the insert handle 20 from the slot 21, thereby undoing the connection between nut 1 2 and nut 2 3. Rotate nut 2 3 and nut 1 2 in sequence to remove them from the screw 1.
