Description

Technical Field

[0001] The present invention relates to the technical field of power transmission, and specifically provides a high-toughness and anti-fatigue alloy trunnion. Background Art

[0002] In power transmission lines, trunnions are generally used to connect power fittings of cables. For example, suspension clamps, strain clamps, etc. need to be hung on tower racks. The design of the trunnion hanging plate needs to meet the strength requirements and be able to withstand the maximum tension of the conductor and wind load. When the cable is affected by wind vibration, the fittings, tower structure members or the cable directly bear alternating loads. After long-term use, the above devices will be damaged, thus shortening the service life of the devices.

[0003] For example, a trunnion hanging plate with the patent number CN210577669U inserts a connecting shaft into the first cavity; secondly, a limiting block is inserted into the limiting ring groove by using a butt joint component; then the first mounting column and the second mounting column are connected by using a connecting component to stably support the rotating block; finally, by rotating the nut, the connecting shaft can be fixed on the tower rack. The trunnion hanging plate composed of the above structure is convenient for disassembling and replacing the ear plate. At the same time, when affected by wind vibration, the hanging plate can rotate in cooperation with the connecting shaft as the clamp swings, reducing the direct acting force of the wind vibration on the clamp and extending the service life of the clamp.

[0004] In the prior art, the problems of easy wear and difficult replacement during the use of the trunnion hanging plate have been solved. However, since the trunnion is at both ends of the power transmission line, when the trunnion is damaged and needs to be replaced, the central hole of the trunnion will become larger due to wear, resulting in unstable fixation of the power transmission line, easy to be affected by wind vibration and cause increased wear, posing a great safety hazard. Moreover, since the trunnion in the power transmission line is at a high altitude, it takes a lot of time for personnel to remove the trunnion during replacement, which is time-consuming and laborious.

[0005] Therefore, a high-toughness and anti-fatigue alloy trunnion is proposed. Summary of the Invention

Specific embodiments

[0033] In order to clearly and completely describe the technical solutions in the embodiments of the present invention, so that the features and advantages can be more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0034] Embodiment 1

[0035] Please refer to Figures 1 to 8 , the present invention provides a high-toughness and anti-fatigue alloy trunnion, used in conjunction with the hanging ring 1, including a trunnion hanging plate 2, a resilient block 3, a durable ring 4, a trigger ring 5, a fixing component 6, a switching component 7, a resilient component 8, a replacement component 9 and an anti-aggravation component 10. The resilient block 3 slidably connected in the trunnion hanging plate 2, the durable ring 4 rotatably connected to the resilient block 3, the trigger ring 5 fixed on the hanging ring 1, the fixing component 6 and the switching component 7 arranged on the left side of the resilient block 3, the resilient component 8 arranged at the front end of the resilient block 3, the replacement component 9 arranged inside the resilient block 3, and the anti-aggravation component 10 arranged at the rear end of the resilient block 3. The hanging ring 1 is rotatably connected inside the durable ring 4. The fixing component 6 is used to lock the resilient block 3 inside the trunnion hanging plate 2. The switching component 7 unlocks the resilient block 3 when the hanging ring 1 drives the trigger ring 5 to rotate. The resilient component 8 enables the resilient block 3 to move forward inside the trunnion hanging plate 2 when the resilient block 3 is unlocked. The replacement component 9 rotates the durable ring 4 in cooperation with the trigger ring 5 when the holes of the durable ring 4 are worn to a set degree. The anti-aggravation component 10 cooperates with the switching component 7 to fix the trigger ring 5 and the resilient block 3 to prevent the wear from aggravating when the holes of the durable ring 4 are completely worn.

[0036] Specifically, the ear shaft hanging plate 2 is made of galvanized steel with a sealing coating, so that the part exposed to the outside all year round has excellent corrosion resistance. The durability ring 4 adopts a low-carbon steel surface carburizing or nitriding process to form a high-hardness wear-resistant layer (such as surface hardness HRC60+), while maintaining the toughness of the core, and the local contact surface at the center hole of the durability ring 4 is quenched to improve wear resistance.

[0037] See also Figures 3 to 4 The fixing component 6 includes a fixing groove 61, a fixing block 62, a fixing spring 63, a fixing pin 64 and a fixing slot 65. The fixing groove 61 is arranged on the left side of the tough block 3 in the ear shaft hanging plate 2. The fixing block 62 is slidably connected in the fixing groove 61. The fixing spring 63 is arranged between the left side of the fixing block 62 and the inner wall of the ear shaft hanging plate 2. The fixing pin 64 is arranged at the right end of the fixing block 62. The fixing slot 65 is arranged on the left side of the tough block 3. The fixing pin 64 cooperates with the fixing slot 65. The cooperation here means that the fixing pin 64 is inserted into the fixing slot 65 under normal conditions.

[0038] See also Figures 4 to 6 The switching component 7 includes a switching rack 71, a front switching chamfer 72, a rear switching chamfer 73 and a buffer unit 74. A switching groove is provided at the upper end of the fixed groove 61. A switching groove (not shown in the figure) is provided. The switching rack 71 is slidably connected in the switching groove. The front switching chamfer 72 and the rear switching chamfer 73 are fixed to the right end of the fixed block 62. The right end of the switching rack 71 cooperates with the trigger ring 5. The cooperation here is that when the hanging ring 1 shakes, the hanging ring 1 drives the trigger ring 5 to rotate, and the rotation of the trigger ring 5 drives the switching rack 71 to move forward and backward. The front switching chamfer 72 and the rear switching chamfer 73 cooperate with the switching rack 71. The cooperation here means that when the switching rack 71 moves forward and backward, the front and rear ends of the switching rack 71 will cooperate with the trigger ring 5. The front switching chamfer 72 or the rear switching chamfer 73 is in fit. Here, the front switching chamfer 72 is taken as an example. When the hanging ring 1 shakes violently, the hanging ring 1 will drive the trigger ring 5 to rotate, and the rotation of the trigger ring 5 will drive the switching rack 71 to move forward and backward. Here, when the switching rack 71 moves forward to a certain distance due to the violent shaking of the hanging ring 1, the switching rack 71 will fit with the front switching chamfer 72 when it moves forward a certain distance, and push the fixing block 62 to the left along the front switching chamfer 72 to squeeze the fixing spring 63. The fixing block 62 moves to the left, driving the fixing pin 64 to move to the left to pull out the fixing slot 65. The buffer unit 74 is arranged at the left end of the fixing block 62, and the buffer unit 74 is used to slowly reset the fixing block 62 to the right.

[0039] See also Figures 4 to 5, the buffer unit 74 includes a buffer block 741, a buffer groove 742, and a buffer film 743. The buffer block 741 is fixedly connected to the left end of the fixed block 62. The buffer groove 742 is formed in the trunnion hanging plate 2. The buffer block 741 is slidably connected to the buffer groove 742. The buffer film 743 is disposed at the left end of the buffer groove 742. A small hole is provided in the center of the buffer film 743 and can be turned outwards to the left. When the buffer block 741 moves to the left, the buffer block 741 can squeeze the gas in the buffer groove 742, causing the buffer film 743 to turn outwards to the left and making the aperture of the small hole larger. When the buffer block 741 moves to the right, the buffer block 741 can draw in the air outside the buffer groove 742 and cause the buffer film 743 to close, leaving only a small hole in the center of the buffer film 743. Thus, when the fixed block 62 moves to the right after squeezing the fixed spring 63, it can be slowly reset by the air pressure in the buffer groove 742, preventing the fixing pin 64 from repeatedly inserting into the fixing slot 65 when the hanging ring 1 shakes violently left and right continuously, and preventing the toughness block 3 from getting stuck when squeezing the toughness spring 82 to increase toughness during the violent shaking of the hanging ring 1.

[0040] Please refer to Figure 7 , the toughness component 8 includes a toughness groove 81 and a toughness spring 82. The toughness groove 81 is formed in the trunnion hanging plate 2. The toughness block 3 is slidably connected to the toughness groove 81. The toughness spring 82 is disposed between the front end of the toughness block 3 and the inner wall of the trunnion hanging plate 2.

[0041] Working principle: During installation, the operator first connects the two ends of the trunnion hanging plate 2 to the tower pole, then inserts the end of the hanging ring 1 with the trigger ring 5 into the central hole of the durable ring 4, fixes the upper and lower ends of the hanging ring 1 to the U-shaped ring, and sequentially connects the power transmission line to the U-shaped ring.

[0042] In the normal state, the power transmission line does not shake, or shakes slightly under the action of a gentle breeze. At this time, the front end of the hanging ring 1 will fit against the front end of the central hole of the durable ring 4 in the center of the trunnion hanging plate 2 and fit against the central hole of the durable ring 4, remaining stationary or having slight frictional sliding, so that the end of the power transmission line can be stably fixed by the trunnion hanging plate 2 in the normal state.

[0043] When the ambient wind speed is relatively high, the transmission line will vibrate violently compared to the normal state. The hanging ring 1 connected to the transmission line will rotate by a large angle. When there is a risk of the transmission line breaking due to being tightened by the violent vibration, at this time, the hanging ring 1 will drive the trigger ring 5 to rotate synchronously. The rotation of the trigger ring 5 drives the switching rack 71 to move back and forth. When the switching rack 71 moves forward or backward a certain distance, the front end or the rear end of the switching rack 71 will be in contact with the front switching chamfer 72 and the rear switching chamfer 73. Here, taking the front switching chamfer 72 as an example, when the switching rack 71 moves forward a certain distance, the front end of the switching rack 71 will be in contact with the front switching chamfer 72 and push the fixing block 62 to the left along the front switching chamfer 72, squeezing the fixing spring 63. The leftward movement of the fixing block 62 drives the fixing pin 64 to move leftward and pull out the fixing slot 65 on the side of the resilient block 3. At this time, when the wind continues to blow the transmission line, the transmission line will continue to vibrate, and then drive the hanging ring 1 and the resilient block 3 to move forward, squeezing the resilient spring 82. When the transmission line is tightened due to violent vibration, the sliding of the resilient block 3 in the trunnion hanger plate 2 and the resilient spring 82 can play a role in relaxing and buffering the transmission line to a certain extent, improving the toughness of the trunnion during use.

[0044] Embodiment 2

[0045] Please refer to Figures 6 to 10, a high-toughness anti-fatigue alloy trunnion is provided, including a replacement component 9. The replacement component 9 includes a trigger block 91, a trigger groove 92, a replacement block 93, a replacement spring 94, a locking block 95, a locking groove 96, and a torsion spring (not shown in the figure). A rotating column 41 is provided at the lower end of the durability ring 4. The durability ring 4 is rotatably connected to the toughness block 3 through the rotating column 41. The trigger groove 92 is opened at the front end of the trunnion hanging plate 2. The trigger block 91 is slidably connected in the trigger groove 92. The replacement block 93 is connected to the front end of the trigger block 91. The replacement spring 94 is arranged between the front end of the replacement block 93 and the inner wall of the toughness block 3. The locking block 95 is fixed to the lower side of the rear end of the replacement block 93. The locking groove 96 is opened on the durability ring 4. The torsion spring is connected between the rotating column 41 and the toughness block 3. The rear end of the trigger block 91 cooperates with the trigger ring 5. Here, the cooperation means that when the central holes of the hanging ring 1 and the durability ring 4 are worn due to long-term use and friction, when the wear reaches a certain degree, the hanging ring 1 moves forward relative to the toughness block 3, driving the trigger ring 5 to move closer to the trigger block 91, making the trigger ring 5 gradually fit with the rear end of the trigger block 91 and pushing the trigger block 91 forward. The locking block 95 cooperates with the locking groove 96. Here, the cooperation means that in the normal use state, the contact surface between the front end of the hanging ring 1 and the durability ring 4 is not worn. At this time, the locking block 95 fits with the locking groove 96 under the action of the replacement spring 94. When the contact surface between the front end of the hanging ring 1 and the durability ring 4 is worn and the wear reaches a certain degree, the trigger ring 5 moves forward relative to the toughness block 3, driving the trigger block 91 to move forward. The forward movement of the trigger block 91 drives the replacement block 93 to move forward, squeezing the replacement spring 94, and causing the replacement block 93 to drive the locking block 95 to move forward and pull out of the locking groove 96.

[0046] Specifically, the torsion spring is made of high-quality steel spring, and its maximum torsional compression amount is not exceeded during use to ensure its service life during long-term compression. The torsion spring is used to provide a circumferential rotational force to the rotating column 41 after the locking block 95 is pulled out of the locking groove 96, so that the rotating column 41 can drive the durability ring 4 to rotate, making the worn surface of the durability ring 4 transfer to the side, and making the front end of the hanging ring 1 fit with the intact inner wall of the durability ring 4.

[0047] Please refer to Figure 10 , specifically, the locking groove 96 can be set to at least two and at most four. In this embodiment, four groups of locking grooves 96 are provided, which also correspond to the durability ring 4 being able to be worn out by the hanging ring 1 four times until it is completely damaged.

[0048] The remaining structures are the same as those in Embodiment 1.

[0049] Working principle: When the trunnion hanging plate 2 and the hanging ring 1 have been fixedly connected to the power transmission line for a long time, due to the wear between the front end of the central hole of the durability ring 4 in the trunnion hanging plate 2 and the hanging ring 1, the power transmission line becomes loose, posing a safety hazard. At this time, the hanging ring 1 will move forward relative to the toughness block 3 due to the wear at the front end of the central hole of the durability ring 4, driving the trigger ring 5 to move closer to the trigger block 91. The trigger ring 5 gradually fits with the rear end of the trigger block 91 and pushes the trigger block 91 forward. The forward movement of the trigger block 91 drives the replacement block 93 to move forward and squeeze the replacement spring 94, and the replacement block 93 drives the locking block 95 to move forward and pull out of the locking groove 96. At this time, the durability ring 4 loses the fixation of the locking block 95. The durability ring 4 and the rotating column 41 rotate under the action of the torsion spring. During the rotation process, the central hole of the durability ring 4 will pull the hanging ring 1 backward along the worn surface until the worn surface is completely rotated to the side of the hanging ring 1. At this time, another locking groove 96 is aligned with the locking block 95, and the locking block 95 is inserted back into the locking groove 96 under the action of the replacement spring 94 to fix the durability ring 4, thereby enabling the trunnion to be put back into use, fixing the hanging ring 1, greatly improving the service life and durability of the trunnion, enhancing the anti-fatigue effect, and reducing the maintenance and replacement costs.

[0050] Embodiment 3

[0051] Please refer to Figures 7 to 12 , a high-toughness anti-fatigue alloy trunnion is provided, including an anti-aggravation component 10. The anti-aggravation component 10 includes a lifting ring 101, a lifting limit groove 102, a lifting limit rod 103, a lifting block 104, and a clamping unit 105. The lifting ring 101 is sleeved on the rotating column 41. The rotating column 41 is provided with an external thread, and the lifting ring 101 is provided with a threaded groove. The external thread cooperates with the threaded groove. The lifting limit groove 102 is arranged at the lower end of the toughness block 3, the lifting limit rod 103 is fixed at the lower end of the lifting ring 101, and the lifting limit rod 103 is slidably connected with the lifting limit groove 102. The lifting block 104 is fixedly connected to the lower end of the lifting limit rod 103, and the clamping unit 105 is arranged at the rear end of the toughness block 3 and fixes the toughness block 3 when the lifting block 104 rises to the uppermost end.

[0052] Specifically, the rear end of the trigger block 91 can be inserted into the tooth gap of the trigger ring 5. When the trigger ring 5 contacts the trigger block 91, the trigger block 91 will be inserted into the tooth gap of the trigger ring 5 to achieve the circumferential fixation of the trigger ring 5, thereby preventing the hanging ring 1 from rotating.

[0053] Please refer to Figures 9 to 12, the clamping unit 105 includes a clamping groove 105a, a clamping lifting rod 105b, a clamping spring 105c, a clamping block 105d, a clamping chamfer 105e and a clamping locking groove 105f. The clamping groove 105a is opened at the rear end of the resilient block 3 in the trunnion hanging plate 2. The clamping lifting rod 105b is slidably connected in the clamping groove 105a. The clamping spring 105c is arranged between the upper end of the clamping lifting rod 105b and the inner wall of the trunnion hanging plate 2. The clamping block 105d is fixed to the front end of the clamping lifting rod 105b. The clamping locking groove 105f is opened on the resilient block 3. A clamping chamfer 105e is arranged on the lower side of the front end of the clamping block 105d. The lower end of the clamping lifting rod 105b cooperates with the upper end of the lifting block 104. Herein, the cooperation means that when the rotating column 41 rotates, the rotating column 41 will drive the lifting ring 101 to move upward under the cooperation of the thread groove and the external thread, and under the limitation of the lifting limiting rod 103 and the lifting limiting groove 102. The upward movement of the lifting ring 101 drives the lifting block 104 to move upward. The upward movement of the lifting block 104 fits with the lower end of the clamping lifting rod 105b and drives the clamping lifting rod 105b to move upward. The front end of the clamping block 105d fits with the rear end of the resilient block 3. The clamping chamfer 105e cooperates with the clamping locking groove 105f. Herein, the cooperation means that when the contact surface between the durable ring 4 and the hanging ring 1 is not worn comprehensively, the front end of the clamping block 105d always fits with the rear end of the resilient block 3, so that the resilient block 3 can fit with the front end of the clamping block 105d under the action of the resilient spring 82. After the durable ring 4 is worn comprehensively, the trigger ring 5 will always push the trigger block 91 forward. The locking block 95 always pulls out of the locking groove 96. The rotating column 41 will always rotate under the action of the torsion spring, driving the lifting block 104 and the clamping lifting rod 105b to continuously rise and squeeze the clamping spring 105c. The upward movement of the clamping lifting rod 105b drives the clamping block 105d to rise until the lifting ring 101 loses the cooperation with the thread groove and the external thread of the rotating column 41. At this time, the continuous rotation of the rotating column 41 cannot drive the lifting ring 101, the lifting block 104, the clamping lifting rod 105b and the clamping block 105d to move upward. At this time, the front end of the clamping chamfer 105e fits with the upper side of the rear end of the resilient block 3. The resilient block 3 moves backward under the action of the resilient spring 82 and pushes the clamping block 105d upward along the clamping chamfer 105e to squeeze the clamping spring 105c until the resilient block 3 drives the clamping locking groove 105f to move to the lower end of the clamping block 105d. At this time, the clamping chamfer 105e moves downward under the action of the clamping spring 105c and inserts into the clamping locking groove 105f. At this time, the rear end of the hanging ring 1 fits with the inner wall of the trunnion hanging plate 2.

[0054] A lifting spring (not shown in the figure) is arranged at the lower end of the lifting block 104. The lower end of the lifting spring is connected to the inner wall of the trunnion hanging plate 2. The lifting spring can provide an upward thrust to the lifting block 104, so that when the torsion spring drives the resilient ring to rotate, the lifting block 104 can assist the lifting ring 101 to lift and assist the resilient ring to rotate.

[0055] A warning block is provided on the clamping block 105d, and a warning groove is provided on the clamping groove 105a. The warning block is slidably connected to the warning groove. The warning block and the warning groove are shown in the figure, and the specific positions can be referred to Figure 9 , the warning groove is opened above the clamping groove 105a, and the warning block is slidably connected in the warning groove directly above the clamping groove 105a. The warning block is made of a striking red appearance material. When all the surfaces of the central through-hole of the durability ring 4 are completely worn, the lifting ring 101 rises, driving the clamping lifting rod 105b to rise. The upper end of the clamping lifting rod 105b can contact the lower end of the warning block and push the warning block to slide upward along the warning groove, and finally a part is exposed outside the trunnion hanging plate 2, so as to facilitate manual quick judgment of whether the trunnion is damaged and timely replacement during maintenance by the staff.

[0056] The remaining structures are the same as those in Embodiment 2.

[0057] Working principle: When the central hole of the durability ring 4 of the trunnion scraper is damaged due to long-term friction with the front end of the hanging ring 1, the hanging ring 1 will drive the trigger ring 5 to move forward. During the forward movement of the trigger ring 5, on the one hand, it will push the trigger block 91 forward, causing the locking block 95 to pull out of the locking groove 96 to unlock the durability ring 4. On the other hand, the trigger ring 5 will drive the switching rack 71 to move forward, so that the switching rack 71 will push the fixed pin 64 to the left and pull out the fixed pin 64 under the action of the front switching chamfer 72, unlocking the resilient block 3. When the central hole of the durability ring 4 is worn multiple times and all the central holes of the durability ring 4 corresponding to each locking groove 96 are damaged, at this time, when the durability ring 4 is unlocked, the locking block 95 cannot lock the durability ring 4 under the action of the hanging ring 1 all the time. Therefore, the durability ring 4 and the rotating column 41 can continue to rotate under the action of the torsion spring. The rotating column 41 rotates, driving the lifting block 104 and the clamping lifting rod 105b to continuously rise and squeeze the clamping spring 105c. The rising of the clamping lifting rod 105b drives the clamping block 105d to rise until the lifting ring 101 loses its fit with the thread groove and the external thread of the rotating column 41. At this time, the rotating column 41 continues to rotate and cannot drive the lifting ring 101, the lifting block 104, the clamping lifting rod 105b and the clamping block 105d to move upward. At this time, the front end of the clamping chamfer 105e fits with the upper side of the rear end of the resilient block 3. Since the resilient block 3 has been unlocked, the resilient block 3 can move backward under the action of the resilient spring 82 and push the clamping block 105d upward along the clamping chamfer 105e to squeeze the clamping spring 105c until the resilient block 3 drives the clamping lock groove 105f to move to the lower end of the clamping block 105d. At this time, the clamping chamfer 105e moves downward under the action of the clamping spring 105c and inserts into the clamping lock groove 105f. At this time, the rear end of the hanging ring 1 fits with the inner wall of the trunnion hanging plate 2, so that when the central hole of the durability ring 4 in the trunnion hanging plate 2 is completely worn, the power transmission line can be pulled to the normal state, and the hanging ring 1 can be completely fixed, waiting for the staff to regularly overhaul and replace the trunnion, preventing the hanging ring 1 from shaking due to the loosening of the central hole of the durability ring 4 and driving the power transmission line to shake. Furthermore, while ensuring the safety of the power transmission line during use, the hanging ring 1 and the durability ring 4 are completely fixed, preventing the wear of the central holes of the hanging ring 1 and the durability ring 4 from intensifying, ensuring the safety of the power transmission line.
