Description

Technical Field

[0001] This invention relates to the field of power transmission line hardware technology, specifically to a high-safety bowl-shaped mounting plate that is easy to assemble and disassemble and its usage method. Background Technology

[0002] In power transmission lines, the bowl-shaped hanging plate serves to suspend the insulator strings and suspension clamps, bearing significant working stress. Its safety performance is crucial to the power transmission line. Power transmission lines are usually erected at high altitudes and are subject to wind forces due to the influence of the high-altitude natural environment.

[0003] In existing technology, the cup head and ball head are generally limited by elastic R-shaped pins to prevent the ball head from falling off. However, at high altitudes, the cup head and ball head are prone to relative swaying due to wind. During long-term operation, the cup head mounting plate continuously bears the static load tension from the conductor and is also affected by various natural factors such as wind, rain, and snow. Under the combined effect of these factors, continuous friction is easily generated between the pin of the cup head mounting plate and the ball head of the insulator string. This friction gradually wears down the surface material of the pin and the ball head, causing the pin to wear out or even deform, which in turn affects its fixing function. This leads to a gradual increase in the movement space of the ball head inside the cup head, and the risk of the ball head detaching from the cup head also increases significantly. Moreover, as a connecting hardware for power transmission lines, the cup head mounting plate is generally installed at high altitudes. The existing cup head mounting plate pins are inconvenient to install due to the high altitude and the bending of the pin ends. Furthermore, when the pin is damaged and needs to be replaced or removed for maintenance, the small operating space inside the cup head mounting plate makes it difficult to remove the pin, resulting in inconvenience for maintenance and replacement.

[0004] Therefore, a high-safety bowl-shaped hanging plate that is easy to assemble and disassemble and its usage method are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a high-safety bowl head bracket that is easy to assemble and disassemble and its usage method. In view of the existing technology, the bowl head bracket and safety pin are inconvenient to disassemble and install, and the safety pin will wear out during use and needs to be inspected regularly. When the safety pin is damaged or deformed, it is easy to increase the risk of the ball head separating from the bowl head bracket, which poses a safety hazard.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-safety ball head bracket for easy assembly and disassembly, used to connect the ball head of an insulator string, includes a ball head bracket, a wear-resistant pad on the upper side of the inner wall of the ball head bracket, a safety pin connected inside the ball head bracket, an anti-detachment ring inserted into the lower side of the inner wall of the ball head bracket, a fixing component inside the ball head bracket, a triggering component on the upper end of the wear-resistant pad, an anti-detachment component on the upper end of the ball head bracket, and a replacement component inside the side wall of the ball head bracket. The ball head is connected between the wear-resistant pad and the safety pin. The fixing component is used to fix the anti-detachment 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 wears thin. The anti-detachment component cooperates with the wear-resistant pad to open the anti-detachment ring and wrap the ball head when the safety pin is completely damaged. The replacement component is used to unlock the safety pin when the anti-detachment ring is opened.

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

[0009] When the anti-detachment ring is stored in the ball socket plate, the fixing slot at the lower end of the anti-detachment ring is aligned with the upper end of the fixing block, and the fixing block is inserted into the fixing slot under the action of the fixing spring.

[0010] Preferably, the plug-in unit includes plug-in blocks fixedly connected to both sides of the lower end of the fixing block, a plug-in chamfer set on the upper end of the plug-in block, and a plug-in groove opened at the lower end of the safety pin. The plug-in chamfer cooperates with the plug-in groove, and the depth of the plug-in groove is less than the depth of the fixing slot.

[0011] When the safety pin is inserted into the ball socket plate to the right, the right end of the safety pin first aligns with the chamfer on the insertion block. As the safety pin continues to move to the right, it pushes the insertion block downwards along the chamfer, causing the insertion block to compress the fixing spring until the chamfer is completely moved to the lower end of the safety pin. When the safety pin continues to move, it causes the lower insertion groove to move directly above the chamfer. At this point, the insertion block returns to its original position under the action of the fixing spring, allowing the chamfer to insert into the insertion groove, thus fixing the safety pin. The depth of the insertion groove is less than the depth of the fixing slot, and the downward movement distance of the chamfer is less than the depth of the fixing groove. The purpose of this design is to prevent the upper end of the fixing block connected to the insertion block from being completely pulled out of the fixing slot when the chamfer moves to the lower end of the safety pin, thus preventing the anti-disengagement ring from popping out of the ball socket plate during the installation of the safety pin.

[0012] Preferably, the triggering component includes a trigger groove disposed within the ball socket mounting plate, a trigger block disposed on the right side of the wear-resistant pad, an unlocking block disposed on the left side of the fixing block, and a trigger spring disposed on the upper end of the wear-resistant pad. The upper end of the trigger spring is fixedly connected to the inner wall of the ball socket mounting plate, the wear-resistant pad is slidably connected to the ball socket mounting plate through the trigger groove, the lower end of the wear-resistant pad engages with the ball head, and the lower end of the trigger block is in contact with the upper end of the unlocking block.

[0013] After the ball head is installed in the ball socket plate, the wear-resistant pad will fit against the ball head under the action of the trigger spring. The lower end of the trigger block fits against the upper end of the unlocking block. When the trigger block moves downward, the trigger block will drive the unlocking block to move downward.

[0014] Preferably, the lower end of the wear-resistant pad is provided with a ball bearing, which is rotatably connected inside the wear-resistant pad, and the lower end of the ball bearing is in contact with the upper end of the ball head.

[0015] The purpose of this design is to reduce the friction between the ball head of the insulator string and the wear-resistant pad after the ball head is installed in the ball socket plate.

[0016] Preferably, the anti-detachment component includes an anti-detachment groove circumferentially formed at the upper end of the fixed groove and an anti-detachment spring disposed in the fixed groove. The anti-detachment ring is slidably connected in the anti-detachment groove, and the two ends of the anti-detachment spring are respectively connected to the front end of the anti-detachment ring and the inner wall of the ball socket hanging plate.

[0017] Preferably, the replaceable component includes a replaceable spring disposed within the ball socket mounting plate and a disassembly lever disposed at the right end of the anti-detachment ring. The right end of the replaceable spring is fixedly connected within the ball socket mounting plate, and the left end of the replaceable spring cooperates with a safety pin. A replaceable groove is provided at the rear end of the ball socket mounting plate, and the disassembly lever extends to the outside of the ball socket mounting plate through the replaceable groove.

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

[0019] The purpose of this design is that when the safety pin is damaged and the anti-detachment ring is unlocked and extends out of the ball joint plate, the red paint on the anti-detachment ring can help maintenance personnel quickly identify the damage to the safety pin and repair it in a timely manner.

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

[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 down the unlocking lever to move the fixing block downwards, so that the fixing chamfer at the top of the fixing block is pulled out of the fixing slot, and the insertion chamfer on both sides at the bottom of the fixing block is pulled out of the insertion slot, thus enabling the disassembly and inspection of the safety pin.

[0022] A method for using a bowl hanging plate includes the aforementioned easy-to-install and highly secure bowl hanging plate, and the following steps:

[0023] The safety pin and ball head are connected to the ball socket plate by setting a fixing component;

[0024] By setting a wear-resistant pad and a triggering component, the lower end of the ball head is made to fit against the safety pin;

[0025] By setting an unlock lever, the safety pin can be easily removed when maintenance is required;

[0026] By installing an anti-detachment ring, the safety pin is prevented from detaching after it wears or deforms.

[0027] By coating the surface of the anti-detachment ring with red pigment, the anti-detachment ring becomes easier to spot after it extends out of the ball socket plate;

[0028] By moving the disassembly lever, the extended anti-detachment ring can be retracted back into the bowl head plate for easy use next time.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] By setting a fixing component inside the ball socket mounting plate, the anti-detachment ring and wear-resistant pad can be fixed inside the ball socket mounting plate after the ball head is installed, making installation convenient. By setting a trigger component, the anti-detachment ring is unlocked after the safety pin is worn, damaged or deformed, allowing the anti-detachment ring to extend out of the ball socket mounting plate, thereby intercepting the ball head installed in the ball socket mounting plate and preventing the ball head from falling off. By setting an anti-detachment spring, the damaged or deformed safety pin is automatically ejected a certain distance inside the ball socket mounting plate, making it convenient for the operator to remove and replace it during high-altitude operations.

[0040] To ensure a clear and complete description of the technical solutions in the embodiments of the present invention, and to make the features and advantages more apparent and understandable, the specific implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] Example 1

[0042] Please see Figures 1 to 4 This invention provides a high-safety bowl head bracket that is easy to assemble and disassemble, comprising a ball head bracket 1, a wear-resistant pad 3 disposed on the upper side of the inner wall of the ball head bracket 1, a safety pin 2 connected to the ball head bracket 1, an anti-detachment ring 4 inserted into the lower side of the inner wall of the ball head bracket 1, a fixing component 5 disposed in the ball head bracket 1, a triggering component 6 disposed on the upper end of the wear-resistant pad 3, an anti-detachment component 7 disposed on the upper end of the ball head bracket 1, and a replacement component 8 disposed in the side wall of the ball head bracket 1. A 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-detachment ring 4 and the safety pin 2 after the ball head 9 is installed. The triggering 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 thin. The anti-detachment component 7 cooperates with the wear-resistant pad 3 to open the anti-detachment ring 4 and wrap the ball head 9 when the safety pin 2 is completely damaged. The replacement component 8 is used to unlock the safety pin 2 when the anti-detachment ring 4 is opened.

[0043] Please see Figures 2 to 4Specifically, the fixing component 5 includes a fixing groove 51 opened in the ball socket plate 1, a fixing block 53 slidably connected in the fixing groove 51, a fixing spring 52 disposed between the lower end of the fixing block 53 and the inner wall of the ball socket plate 1, a fixing slot 54 opened at the lower end of the anti-detachment ring 4, and plug-in units 55 disposed on both sides of the lower end of the fixing block 53. The plug-in units 55 are used to fix the safety pin 2. The upper end of the fixing block 53 cooperates with the fixing slot 54. The cooperation here means that when the anti-detachment ring 4 is stored in the ball socket plate 1, the fixing slot 54 at the lower end of the anti-detachment ring 4 is directly opposite 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] Please see Figures 3 to 4 Specifically, the insertion unit 55 includes insertion blocks 551 fixedly connected to both sides of the lower end of the fixing block 53, an insertion chamfer 552 set on the upper end of the insertion block 551, and an insertion groove 553 opened at the lower end of the safety pin 2. The insertion chamfer 552 and the insertion groove 553 cooperate. The cooperation here means that when the safety pin 2 is inserted into the ball socket plate 1 to the right, the right end of the safety pin 2 first fits against the insertion chamfer 552 on the insertion block 551. As the safety pin 2 continues to move to the right, the safety pin 2 will push the insertion block 551 downward along the insertion chamfer 552, so that the insertion block 551 squeezes the fixing spring 52 until the insertion chamfer 552 moves completely to the lower end of the safety pin 2. When the safety pin 2 continues to move, causing the lower insertion groove 553 to move directly above the insertion chamfer 552, the insertion block 551 returns to its original position under the action of the fixing spring 52, so that the insertion chamfer 552 is inserted into the insertion groove 553, thereby fixing the safety pin 2. The depth of the insertion groove 553 is less than the depth of the fixing slot 54, and the downward movement distance of the insertion chamfer 552 is less than the depth of the fixing groove 51. The purpose of this design is that when the insertion chamfer 552 moves to the lower end of the safety pin 2, the upper end of the fixing block 53 connected to the insertion block 551 will not be completely pulled out of the fixing slot 54, preventing the anti-disengagement ring 4 from being unlocked and ejected from the ball socket hanging plate 1 when installing the safety pin 2.

[0045] Working principle: When connecting the ball head 9 of the insulator string to the ball socket plate 1, the operator first moves the anti-detachment ring 4 into the ball socket plate 1, so that the fixing slot 54 at the lower end of the anti-detachment ring 4 is aligned with the upper end of the fixing block 53. Under the action of the fixing spring 52, the fixing block 53 is inserted into the fixing slot 54 to fix the anti-detachment ring 4. Then, the ball head 9 is sent into the ball socket plate 1, so that the ball head 9 is installed in the designated position in the ball socket plate 1. At this time, the upper end of the ball head 9 is in contact with the lower end of the wear-resistant pad 3 under the action of the trigger spring 64. Then, insert the safety pin 2 into the ball socket plate 1 to the right. During insertion, the right end of the safety pin 2 first engages with the chamfer 552 on the insertion block 551. As the safety pin 2 continues to move to the right, it pushes the insertion block 551 downwards along the chamfer 552, causing the insertion block 551 to compress the fixing spring 52 until the chamfer 552 is completely moved to the lower end of the safety pin 2. When the safety pin 2 continues to move, it causes the lower insertion groove 553 to move directly above the chamfer 552, and the insertion block... 551 will return to its original position under the action of the fixing spring 52, so that the chamfer 552 is inserted into the insertion slot 553, thereby fixing the safety pin 2. Because the downward movement distance of the chamfer 552 is less than the depth of the fixing slot 51, when the chamfer 552 moves to the lower end of the safety pin 2, the upper end of the fixing block 53 connected to the insertion block 551 will not be completely pulled out of the fixing slot 54, preventing the anti-detachment ring 4 from being released due to the installation of the safety pin 2. This allows the ball head 9 of the insulator string to be connected to the ball socket plate 1 by simply placing the ball head... 9. Insert the ball head 9 into the ball socket plate 1, and then insert the safety pin 2 below the ball head 9, so that the ball head 9 moves upward in the ball socket plate 1 until the safety pin 2 is locked by the machined chamfer. This connects the ball head 9 of the insulator string to the ball socket plate 1 and fixes the safety pin 2 to the ball socket plate 1. 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 plate 1. The right-angle edge design also makes the safety pin 2, which is easy to damage and needs to be replaced regularly, easier to produce and process, thus reducing costs.

[0046] Example 2

[0047] Please see Figures 4 to 8This invention provides a high-safety bowl head bracket that is easy to assemble and disassemble, including a trigger component 6. The trigger component 6 includes a trigger groove 61 set in the ball socket bracket 1, a trigger block 62 set on the right side of the wear-resistant pad 3, an unlocking block 63 set on the left side of the fixing block 53, and a trigger spring 64 set on 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 bracket 1. The wear-resistant pad 3 is slidably connected to the ball socket bracket 1 through the trigger groove 61. 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 bracket 1, the wear-resistant pad 3 will fit against the ball head 9 under the action of the trigger spring 64. The lower end of the trigger block 62 fits against the upper end of the unlocking block 63. The purpose of this design 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, safety pin 2, and ball socket mounting plate 1 are installed, the upper end of the ball head 9, under the abutment of the safety pin 2, applies a force to the wear-resistant pad 3 to press the trigger spring 64. This ensures that when the safety pin 2 wears down, the trigger spring 64 can maintain the fit between the ball head 9 and the safety pin 2. The lower end of the wear-resistant pad 3 is equipped with a ball bearing. Since the mounting plate is usually designed as the load-bearing body during use, it mainly bears static tensile force, while 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, resulting in stronger wear resistance. The ball bearing rolls within the wear-resistant pad 3, with the lower end of the ball bearing fitting against the upper end of the ball head 9. The purpose of this design is to reduce the friction between the insulator string ball head 9 and the wear-resistant pad 3 after the ball head 9 is installed in the ball socket mounting plate 1.

[0049] Please see Figures 4 to 7 Specifically, the anti-detachment component 7 includes an anti-detachment groove 71 circumferentially opened at the upper end of the fixed groove 51 and an anti-detachment spring 72 disposed in the fixed groove 51. The anti-detachment ring 4 is slidably connected in the anti-detachment groove 71, and the front ends of the anti-detachment ring 4 at both ends of the anti-detachment spring 72 are connected to the inner wall of the ball socket hanging plate 1.

[0050] Specifically, the replacement component 8 includes a replacement spring 81 installed inside the ball socket mounting plate 1 and a disassembly lever 82 installed at the right end of the anti-detachment ring 4. The right end of the replacement spring 81 is fixedly connected inside the ball socket mounting plate 1, and the left end of the replacement spring 81 cooperates with the safety pin 2. This cooperation means that when the safety pin 2 is installed, the middle part of the safety pin 2 is in contact 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 mounting plate 1, and the disassembly lever 82 extends to the outside of the ball socket mounting plate 1 through the replacement groove 83. When the safety pin 2 is damaged or deformed, the anti-detachment ring 4 extends out of the ball socket mounting plate 1 under the action of the replacement spring 81. The operator only needs to move the disassembly lever 82 to reset the anti-detachment ring 4 and put it back into the ball socket mounting plate 1.

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

[0052] An unlocking lever 102 is provided at the right end of the fixing block 53, and an unlocking groove 101 is provided at the right end of the ball socket mounting plate 1. The unlocking lever 102 extends to the outside of the ball socket mounting plate 1 through the unlocking groove 101. The purpose of this design is that when the safety pin 2 is not completely damaged and needs to be disassembled for maintenance or replacement, the operator only needs to press down the unlocking lever 102 to make the unlocking lever 102 drive the fixing block 53 to move downward, so that the fixing chamfer at the upper end of the fixing block 53 is pulled out of the fixing slot 54, and the insertion chamfers 552 on both sides of the lower end of the fixing block 53 are pulled out of the insertion slot 553, thus realizing the disassembly and maintenance of the safety pin 2.

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

[0054] Working principle: After connecting the insulator string ball head 9 to the ball socket plate 1, the ball head 9 and the hole wall of the ball socket plate 1 are generally hardened, thus exhibiting stronger wear resistance. However, the safety pin 2 is exposed to the external environment and is susceptible to damage from rain, salt spray, etc. Furthermore, the safety pin 2 is typically made of softer materials such as ordinary carbon steel or stainless steel, while the ball socket plate is mostly made of high-strength alloys such as cast steel or forged steel, which have higher hardness. Therefore, the pin is more prone to wear during operation. When the safety pin 2 wears down to the point of damage, as it thins, the ball head 9, under the elastic force of the trigger spring 64 on the anti-disengagement ring 4, remains in contact with the safety pin 2 and moves downwards. As the ball head 9 and the anti-disengagement ring 4 move downwards, the anti-disengagement ring 4 drives the trigger block 62 to move downwards. The downward movement of the trigger block 62 drives the unlocking block 63 to move downwards. When the time is right, the fixing block 53 will move downward, causing the fixing chamfer and the insertion chamfer 552 to move downward, unlocking the anti-detachment ring 4 and the safety pin 2. When the anti-detachment ring 4 is unlocked, it will extend out of the ball socket plate 1 under the action of the anti-detachment spring 72. This allows the anti-detachment ring 4 to block the ball head 9 when the safety pin 2 is damaged, preventing the ball head 9 of the insulator string from detaching from the ball socket plate 1 due to wear of the safety pin 2. Unlocking the safety pin 2 makes it easier to disassemble and replace it when it is damaged. Compared with the traditional safety pin 2, it is not necessary to straighten the end of the safety pin 2 before removing it. The setting of the replacement spring 81 can further push the safety pin 2 to the left a distance after it is unlocked, making it easier for the operator to remove the safety pin 2. The red paint on the anti-detachment ring 4 can help maintenance personnel quickly identify the damage to the safety pin 2 and repair it in time.

[0055] Example 3

[0056] A method for using a bowl hanging plate is provided, including the easy-to-install and highly secure bowl hanging plate described in the above embodiments, and the following steps:

[0057] The safety pin 2 and the ball head 9 are connected to the ball socket plate 1 by setting the fixing component 5;

[0058] By setting the wear-resistant pad 3 and the triggering component 6, the lower end of the ball head 9 is made to fit with the safety pin 2;

[0059] By setting the unlock lever 102, the safety pin 2 can be easily removed when maintenance is required;

[0060] By installing the anti-detachment ring 4, the safety pin 2 is prevented from detaching after it is worn or deformed;

[0061] By coating the surface of the anti-detachment ring 4 with red pigment, the anti-detachment ring 4 becomes easier to spot after it extends out of the ball socket hanging plate 1;

[0062] By moving the disassembly lever 82, the extended anti-detachment ring 4 can be retracted back into the bowl head plate for easy use next time.
