Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line hardware, in particular to a high-safety bowl head hanging plate that is easy to disassemble and assemble, and a method for using the same. Background Art

[0002] In transmission lines, bowl-shaped hanging plates serve to suspend insulator strings and suspension clamps, and are subject to significant working stress. Their safety performance is crucial to transmission lines, and power system transmission lines are typically erected at high altitudes. Affected by the natural environment at high altitudes, these lines are subject to certain wind forces.

[0003] In the prior art, the bowl and ball heads are generally secured with elastic R-shaped pins to prevent them from falling off. However, at high altitudes, the bowl and ball heads are susceptible to relative shaking due to wind. During long-term operation, the bowl head bracket will continuously bear the static load tension from the conductors and will also be affected by various natural factors such as wind, rain, and snow. These factors can easily cause continuous friction between the bowl head bracket's pins and the ball heads of the insulator strings. This friction will gradually wear away the surface materials of the pin and the ball head, causing the pin to wear and even deform, thereby affecting its fixing function, causing the ball head to gradually increase its activity space inside the bowl head, and significantly increasing the risk of the ball head detaching from the bowl head. In addition, the bowl head hanging plate is used as a connecting hardware for the transmission line and is generally installed at high altitudes. On the one hand, the existing bowl head hanging plate pin is inconvenient to install due to high-altitude operations and the bent end of the pin. On the other hand, when the pin is damaged and needs to be replaced, or needs to be removed for inspection, the operating space inside the bowl head hanging plate is small and the pin is difficult to remove, resulting in inconvenience in maintenance and replacement.

[0004] Therefore, a high-safety bowl head hanging plate that is easy to disassemble and assemble and a method for using the same are proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-safety bowl head hanging plate that is easy to disassemble and assemble, and a method for using the same. In view of the fact that the bowl head hanging plate and the safety pin in the prior art are inconvenient to disassemble and install, and the safety pin will wear out during use and requires regular maintenance, when the safety pin is damaged or deformed, it is easy to increase the risk of the ball head and the bowl head hanging plate being detached, posing a safety hazard.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A high-safety bowl head hanging plate that is easy to disassemble and assemble is used to connect the ball head of the insulator string, including a ball socket hanging plate, a wear-resistant pad arranged on the upper side of the inner wall of the ball socket hanging plate, a safety pin connected to the ball socket hanging plate, an anti-slip ring inserted on the lower side of the inner wall of the ball socket hanging plate, a fixing component arranged in the ball socket hanging plate, a triggering component arranged at the upper end of the wear-resistant pad, an anti-slip component arranged at the upper end of the ball socket hanging plate, and a replacement component arranged in the side wall of the ball socket hanging plate, the ball head is connected between the wear-resistant pad and the safety pin, the fixing component is used to fix the anti-slip ring and the safety pin after the ball head is installed, the triggering component is used to cooperate with the wear-resistant pad to keep the ball head and the safety pin in contact when the safety pin is worn and thinned, the anti-slip component cooperates with the wear-resistant pad to open the anti-slip ring to wrap the ball head when the safety pin is completely damaged, and the replacement component is used to unlock the safety pin when the anti-slip ring is opened.

[0008] Preferably, the fixing component includes a fixing groove provided in the ball socket hanging plate, a fixing block slidably connected in the fixing groove, a fixing spring provided between the lower end of the fixing block and the inner wall of the ball socket hanging plate, a fixing slot provided at the lower end of the anti-slip ring, and plug-in units provided on both sides of the lower end of the fixing block, the plug-in unit is used to fix the safety pin, and the upper end of the fixing block cooperates with the fixing slot.

[0011] When the safety pin is inserted into the ball socket hanging plate to the right, the right end of the safety pin first fits into the plug chamfer on the plug block. As the safety pin continues to move to the right, the safety pin will push the plug block downward along the plug chamfer, causing the plug block to squeeze the fixing spring until the plug chamfer is completely moved to the lower end of the safety pin. When the safety pin continues to move, it drives the plug slot at the lower end to move to just above the plug chamfer. At this time, the plug block is reset upward under the action of the fixing spring, causing the plug chamfer to be inserted into the plug slot, thereby fixing the safety pin. The depth of the plug slot is less than the depth of the fixing slot, and the downward movement distance of the plug chamfer is less than the depth of the fixing slot. The purpose of the design here is that when the plug chamfer moves to the lower end of the safety pin, the upper end of the fixing block connected to the plug block will not be completely pulled out of the fixing slot, thereby preventing the anti-slip ring from being unlocked and popping out of the ball socket hanging plate when the safety pin is installed.

[0018] Preferably, the anti-ring-off surface layer is coated with red pigment.

[0019] The purpose of this design is that when the safety pin is damaged and the anti-slip ring is unlocked and extends out of the ball socket hanging plate, the red pigment of the anti-slip ring can help maintenance personnel quickly identify the damage of the safety pin and repair it in time.

[0020] Preferably, an unlocking lever is provided at the right end of the fixing block, an unlocking slot is provided at the right end of the ball socket hanging plate, and the unlocking lever extends to the outside of the ball socket hanging plate through the unlocking slot.

[0021] The purpose of this design is that when the safety pin is not completely damaged and needs to be disassembled for inspection or replacement, the operator only needs to press the unlocking lever downward, so that the unlocking lever drives the fixed block to move downward, so that the fixed chamfer on the upper end of the fixed block is pulled out of the fixed slot, and the plug-in chamfers on both sides of the lower end of the fixed block are pulled out of the plug-in slots, so that the safety pin can be disassembled and inspected.

[0022] A method for using a bowl head hanging plate comprises the above-mentioned high-safety bowl head hanging plate that is easy to disassemble and assemble, and the following steps:

By arranging an anti-slip spring, the damaged or deformed safety pin automatically pops out a certain distance from the ball socket hanging plate, which is convenient for the operator to take out and replace it during high-altitude operations.

[0040] To clearly and completely describe the technical solutions in the embodiments of the present invention and to make the features and advantages more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Example 1

[0042] See also Figures 1 to 4 The present invention provides a high-safety bowl head hanging plate that is easy to disassemble and assemble, comprising a ball socket hanging plate 1, a wear-resistant pad 3 arranged on the upper side of the inner wall of the ball socket hanging plate 1, a safety pin 2 connected to the ball socket hanging plate 1, an anti-slip ring 4 inserted on the lower side of the inner wall of the ball socket hanging plate 1, a fixing component 5 arranged in the ball socket hanging plate 1, a trigger component 6 arranged at the upper end of the wear-resistant pad 3, an anti-slip component 7 arranged at the upper end of the ball socket hanging plate 1, and a replacement component 8 arranged in the side wall of the ball socket hanging plate 1. The ball head 9 is connected between the wear-resistant pad 3 and the safety pin 2. The fixing component 5 is used to fix the anti-slip ring 4 and the safety pin 2 after the ball head 9 is installed. The trigger component 6 is used to cooperate with the wear-resistant pad 3 to keep the ball head 9 and the safety pin 2 in contact when the safety pin 2 is worn and thinned. When the safety pin 2 is completely damaged, the anti-slip component 7 cooperates with the wear-resistant pad 3 to open the anti-slip ring 4 to wrap the ball head 9. The replacement component 8 is used to unlock the safety pin 2 when the anti-slip ring 4 is opened.

[0043] See also Figures 2 to 4Specifically, the fixing component 5 includes a fixing groove 51 provided in the ball socket hanging plate 1, a fixing block 53 slidably connected to the fixing groove 51, a fixing spring 52 provided between the lower end of the fixing block 53 and the inner wall of the ball socket hanging plate 1, a fixing slot 54 provided at the lower end of the anti-slip ring 4 and a plug-in unit 55 provided on both sides of the lower end of the fixing block 53. The plug-in unit 55 is used to fix the safety pin 2, and the upper end of the fixing block 53 cooperates with the fixing slot 54. The cooperation here means that when the anti-slip ring 4 is received in the ball socket hanging plate 1, the fixing slot 54 at the lower end of the anti-slip ring 4 is opposite to the upper end of the fixing block 53, and the fixing block 53 is inserted into the fixing slot 54 under the action of the fixing spring 52.

[0044] See also Figures 3 and 4 Specifically, the plug-in unit 55 includes a plug-in block 551 fixedly connected to both sides of the lower end of the fixed block 53, a plug-in chamfer 552 set at the upper end of the plug-in block 551, and a plug-in slot 553 opened at the lower end of the safety pin 2. The plug-in chamfer 552 cooperates with the plug-in slot 553. The cooperation here means that when the safety pin 2 is inserted into the ball socket hanging plate 1 to the right, the right end of the safety pin 2 first fits with the plug-in chamfer 552 on the plug-in block 551. As the safety pin 2 continues to move to the right, the safety pin 2 will push the plug-in block 551 downward along the plug-in chamfer 552, so that the plug-in block 551 squeezes the fixed spring 52 until the plug-in chamfer 552 is completely moved to the lower end of the safety pin 2 When the safety pin 2 continues to move, the plug-in slot 553 at the lower end moves to just above the plug-in chamfer 552. At this time, the plug-in block 551 is reset upward under the action of the fixing spring 52, so that the plug-in chamfer 552 is inserted into the plug-in slot 553, thereby fixing the safety pin 2. The depth of the plug-in slot 553 is less than the depth of the fixing slot 54, and the downward movement distance of the plug-in chamfer 552 is less than the depth of the fixing slot 51. The purpose of this design is that when the plug-in chamfer 552 moves to the lower end of the safety pin 2, the upper end of the fixing block 53 connected to the plug-in block 551 will not be completely pulled out of the fixing slot 54, preventing the anti-slip ring 4 from being unlocked and popping out of the ball socket hanging plate 1 when the safety pin 2 is installed.

[0045] Working principle: When connecting the ball head 9 of the insulator string with the ball socket hanging plate 1, the operator first moves the anti-slip ring 4 to be stored in the ball socket hanging plate 1, so that the fixing slot 54 at the lower end of the anti-slip ring 4 is aligned with the upper end of the fixing block 53. The fixing block 53 is inserted into the fixing slot 54 under the action of the fixing spring 52 to fix the anti-slip ring 4. Then the ball head 9 is sent into the ball socket hanging plate 1 and installed in the designated position in the ball socket hanging plate 1. At this time, the upper end of the ball head 9 is fitted with the lower end of the wear-resistant pad 3 under the action of the trigger spring 64. , and then insert the safety pin 2 to the right into the ball socket hanging plate 1. During the insertion process, the right end of the safety pin 2 first fits into the plug chamfer 552 on the plug block 551. As the safety pin 2 continues to move to the right, the safety pin 2 will push the plug block 551 downward along the plug chamfer 552, so that the plug block 551 squeezes the fixing spring 52 until the plug chamfer 552 is completely moved to the lower end of the safety pin 2. When the safety pin 2 continues to move, the plug slot 553 at the lower end moves to the top of the plug chamfer 552, the plug block 551 will reset upward under the action of the fixing spring 52, so that the plug chamfer 552 is inserted into the plug groove 553, thereby fixing the safety pin 2. Because the downward movement distance of the plug chamfer 552 is less than the depth of the fixing groove 51, when the plug chamfer 552 moves to the lower end of the safety pin 2, the upper end of the fixing block 53 connected to the plug block 551 will not be completely pulled out of the fixing slot 54, preventing the anti-drop ring 4 from being released due to the installation of the safety pin 2, so that when installing the insulator string ball head 9 and the ball socket hanging plate 1, only the ball head needs to be inserted. 9 is placed in the ball socket hanging plate 1, and then the safety pin 2 is inserted under the ball head 9, so that the ball head 9 moves up in the ball socket hanging plate 1 until the safety pin 2 is locked by the car chamfer. The connection between the insulator string ball head 9 and the ball socket hanging plate 1 can be achieved, and the safety pin 2 and the ball socket hanging plate 1 can be fixed. The operation is simple and the installation is convenient. When installing the safety pin 2, there is no need to use tools to bend the end of the safety pin 2 and fix it to the ball socket hanging plate 1. The right-angle edge mounting design also makes it easier to produce and process the safety pin 2 that is easy to damage and needs to be replaced regularly, thereby reducing costs.

[0046] Example 2

[0047] See also Figures 4 to 8, provides a high-security bowl head hanging plate that is easy to disassemble and assemble, including a trigger component 6, the trigger component 6 includes a trigger groove 61 arranged in the ball socket hanging plate 1, a trigger block 62 arranged on the right side of the wear-resistant pad 3, an unlocking block 63 arranged on the left side of the fixed block 53, and a trigger spring 64 arranged at the upper end of the wear-resistant pad 3, the upper end of the trigger spring 64 is fixedly connected to the inner wall of the ball socket hanging plate 1, the wear-resistant pad 3 is slidably connected to the ball socket hanging plate 1 through the trigger groove 61, and the lower end of the wear-resistant pad 3 cooperates with the ball head 9. The cooperation here means that when the ball head 9 is installed in the ball socket hanging plate 1, the wear-resistant pad 3 will be in contact with the ball head 9 under the action of the trigger spring 64, and the lower end of the trigger block 62 is in contact with the upper end of the unlocking block 63. The purpose of the design here is that when the trigger block 62 moves downward, the trigger block 62 will drive the unlocking block 63 to move downward.

[0048] Specifically, after the ball head 9, the safety pin 2 and the ball socket hanging plate 1 are installed, the ball head 9 is in contact with the safety pin 2, and the upper end of the ball head 9 gives the wear-resistant pad 3 a force to squeeze the trigger spring 64, so that when the safety pin 2 is worn later, the trigger spring 64 can keep the ball head 9 and the safety pin 2 in contact. A ball is provided at the lower end of the wear-resistant pad 3. Since the hanging plate is usually designed as a load-bearing body during use, the hanging plate mainly bears static tensile force, and the dynamic friction is mainly concentrated on the safety pin 2. Therefore, the hole wall and the ball head 9 are hardened or coated for protection, and are more wear-resistant. The ball is rolled and connected in the wear-resistant pad 3, and the lower end of the ball is in contact with the upper end of the ball head 9. The purpose of the design here is that after the ball head 9 is installed in the ball socket hanging plate 1, the ball can reduce the friction between the insulator string ball head 9 and the wear-resistant pad 3.

[0049] See also Figures 4 to 7 Specifically, the anti-slip component 7 includes an anti-slip groove 71 annularly opened at the upper end of the fixed groove 51 and an anti-slip spring 72 arranged in the fixed groove 51. The anti-slip ring 4 is slidably connected in the anti-slip groove 71, and the two ends of the anti-slip spring 72 are connected to the front end of the anti-slip ring 4 and the inner wall of the ball socket hanging plate 1.

[0050] Specifically, the replacement component 8 includes a replacement spring 81 arranged in the ball socket hanging plate 1 and a disassembly lever 82 arranged at the right end of the anti-slip ring 4. The right end of the replacement spring 81 is fixedly connected to the ball socket hanging plate 1, and the left end of the replacement spring 81 cooperates with the safety pin 2. The cooperation here means that when the safety pin 2 is installed, the middle part of the safety pin 2 fits with the left end of the replacement spring 81 and squeezes the replacement spring 81. A replacement groove 83 is provided at the rear end of the ball socket hanging plate 1, and the disassembly lever 82 extends to the outside of the ball socket hanging plate 1 through the replacement groove 83. When the safety pin 2 is damaged or deformed, the anti-slip ring 4 extends out of the ball socket hanging plate 1 under the action of the replacement spring 81. The operator only needs to toggle the disassembly lever 82 to reset the anti-slip ring 4 and re-store it into the ball socket hanging plate 1.

[0051] The surface of the anti-slip ring 4 is coated with red pigment. The purpose of this design is that when the safety pin 2 is damaged, the anti-slip ring 4 is unlocked and extends out of the ball socket hanging plate 1. The red pigment of the anti-slip ring 4 can help maintenance personnel quickly identify that the safety pin 2 is damaged and repair it in time.

[0052] An unlocking lever 102 is provided at the right end of the fixed block 53, and an unlocking slot 101 is provided at the right end of the ball socket hanging plate 1. The unlocking lever 102 extends to the outside of the ball socket hanging plate 1 through the unlocking slot 101. The purpose of this design is that when the safety pin 2 is not completely damaged and needs to be disassembled for inspection or replacement, the operator only needs to press the unlocking lever 102 downward so that the unlocking lever 102 drives the fixed block 53 to move downward, so that the fixed chamfer at the upper end of the fixed block 53 is pulled out of the fixed slot 54, and the plug-in chamfers 552 on both sides of the lower end of the fixed block 53 are pulled out of the plug-in slots 553, so that the safety pin 2 can be disassembled and repaired.

[0053] The rest of the structure is the same as that of Example 1.

[0054] Working principle: After connecting the ball head 9 of the insulator string and the ball socket hanging plate 1, since the hole wall of the ball head 9 and the ball socket hanging plate 1 is generally hardened, they are more wear-resistant. On the one hand, the safety pin 2 is exposed to the external environment and is easily affected by rain, salt spray, etc. and its wear resistance is affected. On the other hand, the safety pin 2 is usually made of softer materials such as ordinary carbon steel and stainless steel, while the bowl head hanging plate is mostly made of high-strength alloys such as cast steel and forged steel with higher hardness. Therefore, during operation, the pin body is more susceptible to wear. When the safety pin 2 is worn and damaged, as the safety pin 2 wears and becomes thinner, the ball head 9 will trigger the elastic member 64 on the anti-slip ring 4, maintain contact with the safety pin 2 and move downward. When the ball head 9 and the anti-slip ring 4 move downward, the anti-slip ring 4 will drive the trigger block 62 to move downward, and the downward movement of the trigger block 62 will drive the unlocking block 63 to move downward, and the unlocking block 63 will move downward. When the safety pin 2 is damaged, the anti-slip ring 4 extends out of the ball and socket hanging plate 1, so that the ball head 9 of the insulator string is prevented from being disconnected from the ball and socket hanging plate 1 due to the wear of the safety pin 2. When the safety pin 2 is unlocked, it can make it more convenient to disassemble and replace the safety pin 2 when it is damaged. Compared with the traditional safety pin 2, there is no need to straighten the end of the safety pin 2 and then take it out. The setting of the replacement spring 81 can further pop the safety pin 2 to the left for a distance after the safety pin 2 is unlocked, making it convenient for the operator to take out the safety pin 2. The red pigment of the anti-slip ring 4 can help maintenance personnel quickly identify that the safety pin 2 is damaged and repair it in time.
