Description

Technical Field

[0001] The invention belongs to the field of electric power equipment, in particular to a grounding hook device capable of being grounded with a grounding wire and a use method thereof. Background Art

[0002] In the power system, grounding is one of the key links to ensure the safe and stable operation of the entire network. It is not only related to the long-term reliability of the equipment, but also directly related to personnel safety and environmental safety. As the main carrier of power transmission, the grounding design and implementation of the transmission line is particularly critical. As a bridge connecting the transmission line and the earth, the grounding wire plays multiple roles: the first is to protect the equipment from damage by lightning strikes. By guiding the lightning current safely into the ground, it effectively reduces the risk of damage to the transmission line and connected equipment caused by lightning strikes; secondly, the grounding wire can quickly eliminate the ground current generated by system failures or abnormal operations, prevent the equipment from overheating or damage caused by current accumulation, and maintain the overall stability of the system; thirdly, good grounding can also suppress electromagnetic interference and protect the normal operation of surrounding sensitive electronic equipment.

[0003] However, the traditional practice of implementing grounding in high-altitude power transmission lines, especially hanging the grounding wire on the grounding hook, often requires workers to wear safety protection equipment and perform high-altitude climbing operations, which not only places high demands on the physical fitness and skills of the workers, but also increases the difficulty and risk of operations when facing emergency maintenance tasks or severe weather conditions, such as heavy rain, strong winds, thunder and lightning. In addition, high-altitude operations themselves are accompanied by extremely high safety risks. Workers may suffer serious accidents such as electric shock and falls due to physical exhaustion, operational errors or sudden weather changes, which poses a great threat to personal safety. Summary of the invention

[0004] The purpose of the present invention is to provide a grounding hook device and method that can be used to hook a grounding wire on the ground, so as to solve the problem that workers need to climb high to work, which is prone to danger.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: A grounding hook device capable of being hooked to a grounding wire on the ground, comprising: The hook body is in an inverted L shape, and is composed of a horizontal section and a vertical section connected in one piece. A secondary pull rope is provided at the right end of the horizontal section, and a main pull rope is provided at the left end of the horizontal section. A clamping block is connected to the vertical section of the hook body in a damping rotation manner and is used to fix the aluminum rod. The left end of the clamping block is fixedly connected to a left pull rope, and the right end of the clamping block is fixedly connected to a right pull rope; The clamping structure includes a locking pin and a spring, which are arranged in the hook body. The top of the locking pin contacts the bottom of the clamping block, the bottom of the spring is fixedly connected to the hook body, and the top of the spring is fixedly connected to the bottom of the pin lock.

[0006] Preferably, a main through hole is opened at the left end of the transverse section, and the main pull rope is connected and fixed through the main through hole, and a secondary through hole is opened at the right end of the transverse section, and the secondary pull rope is connected and fixed through the secondary through hole.

[0007] Preferably, a left through hole is opened at the left end of the card block, and the left pull rope is connected and fixed through the left through hole; a right through hole is opened at the right end of the card block, and the right pull rope is connected and fixed through the right through hole.

[0008] Preferably, the block is an obtuse triangle block, and the obtuse angle is located on the left side of the block.

[0009] Preferably, the length of the block is greater than the width of the cross section of the hook body.

[0010] Preferably, a groove is formed at the bottom of the transverse section of the hook body.

[0011] Preferably, a rotating bolt is threadedly connected to the clamping block, a gasket is provided on the rotating bolt, and the gasket is in contact with the clamping block.

[0012] Preferably, a through slot is formed in the vertical section of the hook body, the clamping block passes through the through slot, and an interference fit is formed between the through slot and the clamping block.

[0013] Preferably, a limiting groove is provided on the top of the block.

[0014] On the other hand, the present invention provides a method for using a grounding hook capable of being hooked to a grounding wire on the ground. The grounding hook device capable of being hooked to a grounding wire on the ground is used, and the specific operation steps are as follows: (1) Throw the auxiliary rope over the aluminum rod by hand, and the operator stands on the ground and pulls the auxiliary rope by hand to pull the hook body up; (2) Raise the hook body and hang it on the aluminum rod. Pull the main pull rope and the auxiliary pull rope during the rise to ensure the balance of the hook body. (3) Pull the left pull rope to move the right end of the clamp upwards, and the clamp cooperates with the hook body to fix the aluminum rod; (4) The lock pin is lifted upward under the elastic force of the spring, and the lock pin is lifted upward to lock the position of the block, completing the installation of the hook body and performing the insulation operation; (5) After the operation is completed, pull the right rope to move the right side of the block downward to unlock the aluminum rod; (6) Pull the main pull rope to remove the hook body from the aluminum rod.

[0015] The beneficial effects of the present invention are as follows: By operating the hook body and the card block by pulling the rope, the installation process of the grounding hook is simplified. The operator does not need to climb to a high place, but only needs to pull the rope on the ground to operate the hook body and the card block, so as to achieve fast and accurate installation of the hook, which greatly improves the working efficiency, ensures the safety of the operators, avoids the risks brought by high-altitude operations, and provides more reliable safety protection for work scenarios such as the power industry that require frequent grounding operations.

[0016] A damping connection is adopted between the block and the hook body, so that the block can stay and be fixed stably at any angle of the hook body, adapting to aluminum rods of different sizes or shapes. The operator can ensure that the hook can fit tightly and achieve stable suspension by adjusting the angle of the block.

[0017] By shifting the center of gravity of the block to the left, the weight of the hook body is balanced, avoiding the hook body from tilting due to unstable center of gravity during operation, ensuring the accuracy of installation and reducing safety hazards caused by improper operation or external interference.

[0024] The present invention provides a grounding hook device which can be used to hook a grounding wire on the ground and a method for using the same. The hook body and the clamping block are operated by pulling a rope, so that an operator can install the grounding hook on the ground, thereby ensuring the safety of the operator. The operation is simple and convenient, and the operator does not need to climb high to perform high-altitude operations. Maintenance work can also be carried out in emergency situations or extreme weather.

[0025] Example 1 like Figure 1-Figure 4 As shown, a grounding hook device capable of being connected to a grounding wire on the ground comprises: The hook body 1 is inverted L-shaped and is composed of a horizontal section and a vertical section connected in one piece. A secondary pull rope 12 is provided at the right end of the horizontal section, a main through hole 3 is provided at the left end of the horizontal section, and the main pull rope 11 passes through the main through hole 3 to be tied and fixed to the hook body. A main pull rope 11 is provided at the left end of the horizontal section, and a secondary through hole 4 is provided at the right end of the horizontal section, and the secondary pull rope 12 passes through the secondary through hole 4 to be tied and fixed to the hook body. The clamping block 5 is connected to the vertical section of the hook body 1 in a damping rotation manner and is used to fix the aluminum rod 2. The left end of the clamping block 5 is fixedly connected with a left pull rope 13, and the left end of the clamping block 5 is provided with a left through hole 6. The left pull rope 13 passes through the left through hole 6 to be tied and fixed to the clamping block 5. The right end of the clamping block 5 is fixedly connected with a right pull rope 14, and the right end of the clamping block 5 is provided with a right through hole 7. The right pull rope 14 passes through the right through hole 7 to be tied and fixed to the clamping block 5. The clamping structure includes a locking pin 8 and a spring 9, which are arranged in the hook body 1. The top of the locking pin 8 contacts the bottom of the card block 5, the bottom of the spring 9 is fixedly connected to the hook body 1, the top of the spring 9 is fixedly connected to the bottom of the pin lock, and a card slot 22 is opened at the bottom of the card block 5 corresponding to the position of the locking pin 8. The locking pin 8 is inserted into the card slot 22. The locking pin 8 maintains the locking state of the card block 5 through the elastic force of the spring 9. The top of the locking pin 8 contacts the card slot 22 to fix the position of the card block 5. When not working, the locking pin 8 is stuck in the slot 22 at the bottom end of the block 5 so that it cannot move. A spring 9 is arranged directly below the locking pin 8. When the left pull rope 13 is pulled down with force, the right end of the block 5 rises to press the aluminum rod 2. The block 5 is stuck in the aluminum rod 2 below the horizontal end of the hook body 1. At the same time, the spring 9 is lifted upward so that the locking pin 8 is stuck in the bottom limit of the block 5 to complete the installation. When the operation is completed, the right pull rope 14 is pulled down to pull off the block 5 and the aluminum rod 2.

[0026] As a preferred example of the above embodiment, the top of the pin lock 8 is arc-shaped to prevent it from being sluggish when sliding in the slot 22 and affecting normal installation.

[0027] As a preferred example of the above embodiment, the center of gravity of the block 5 is located on the left side of the vertical section of the hook body 1, and the counterweight on the left side of the device is increased to ensure the overall balance of the device and avoid operational inconvenience caused by uneven weight distribution.

[0028] As a specific example of the above embodiment, the block 5 is an obtuse triangle block, and the obtuse angle is located on the left side of the block 5, which reduces the weight on the right side while balancing the center of gravity, making it easier to lift the right side of the block 5 later.

[0029] As a preferred example of the above embodiment, the length of the block 5 is greater than the width of the horizontal section of the hook body 1, ensuring that after rotation, the block 5 has sufficient length to cooperate with the horizontal section of the hook body 1 to fix the aluminum rod 2.

[0030] As a preferred example of the above embodiment, a groove 15 is provided at the bottom of the horizontal section of the hook body 1 , which matches the shape of the aluminum rod 2 , making it more stable when fixing the aluminum rod 2 and reducing the sliding of the aluminum rod 2 .

[0031] As a preferred example of the above embodiment, the groove 15 is provided with anti-slip grooves to increase the friction between the groove 15 and the aluminum rod 2 to prevent the aluminum rod 2 from loosening due to external force; As a preferred example of the above embodiment, a rubber pad is arranged in the groove 15. The rubber pad can be deformed to adapt to aluminum rods 2 of different sizes, and can squeeze the aluminum rod 2 to increase friction, prevent the aluminum rod 2 from sliding or shifting in the groove 15, and improve the stability of the overall structure.

[0032] As a preferred example of the above embodiment, the vertical section of the hook body 1 is provided with a through slot 16, and the clamping block 5 passes through the through slot 16. The through slot 16 and the clamping block 5 are in interference fit, and can only be swung downward by external force, and cannot be swung left and right or forward and backward. When no pull rope is used for pulling, loosening or relative movement can be prevented. The clamping and loosening of the clamping block 5 and the aluminum rod 2 are controlled by the left pull rope 13 and the right pull rope 14, and the fixing effect of the aluminum rod 2 is good.

[0033] As a preferred example of the above embodiment, the pull rope is made of high-strength, wear-resistant material, such as nylon or polyester fiber, to ensure that it is not easy to break during long-term use; the hook body 1 is made of lightweight but high-strength material, such as aluminum alloy or stainless steel, to reduce weight and improve corrosion resistance.

[0034] When in use, the upper line throws one end of the auxiliary pull rope 12 over the aluminum rod 2 under the existing grounding wire clamp by hand or drone lead. At this time, one end of the auxiliary pull rope 12 and one end of the main pull rope 11 are both hanging to the ground. The operator stands on the ground and pulls the auxiliary pull rope 12 downward, thereby pulling the hook body 1 at the other end of the auxiliary pull rope 12 up. At the same time, the operator can pull the main pull rope 11. Since the main pull rope 11 at the other end is connected to the main through hole 3 of the hook body 1, the hook body When the hook body 1 rises, the main pull rope 11 is pulled to ensure the stability and balance when the hook body 1 is clamped on the aluminum rod 2. When the hook body 1 is clamped on the aluminum rod 2, the operator pulls the left pull rope 11 to make the right end of the clamping block 5 rise, limit and fix the aluminum rod 2, and at the same time, the pin lock 8 moves up to fix the position of the clamping block 5; after the work is completed, the right pull rope 14 is pulled, and the right end of the clamping block 5 overcomes the pressure of the pin lock 8 and moves down, the aluminum rod 2 is unlocked, and the operator pulls the main pull rope 11 to guide the hook body 1 down.

[0035] Example 2 Example 2 is a preferred example. Figure 5-Figure 7 As shown, the difference from Example 1 is that a threaded hole is formed on the clamping block 5, a rotating bolt 17 is threadedly connected to the inner thread of the threaded hole, a gasket 18 is provided on the rotating bolt 17, and the gasket 18 is arranged between the clamping block 5 and the rotating bolt 17. The rotating bolt 17 is used to adjust the resistance between the clamping block 5 and the hook body 1, thereby making the fixing strength of the clamping block 5 to the aluminum rod 2 different.

[0036] As a preferred example of the above embodiment, there is one threaded hole or two opposite threads on the clamping block 5 to achieve adjustment from one side or both sides.

[0037] As a preferred example of the above embodiment, a support sheet 20 is fixedly connected to the rotating bolt 17. The support sheet 20 is in direct contact with the gasket 18, and has a larger contact area with the gasket 18, resulting in a better squeezing and pushing effect.

[0038] As a preferred example of the above embodiment, the gasket 18 is in contact with the rotating bolt 17. When the rotating bolt 17 rotates, the gasket 18 is pushed inward without causing the gasket 18 to rotate. The gasket 18 is made of a hard material.

[0039] As a preferred example of the above embodiment, a cross slot 19 is formed on the rotating bolt 17 for a screwdriver to rotate the rotating bolt 17 for subsequent adjustment.

[0040] As a preferred example of the above embodiment, Figure 8 As shown, a knob is fixedly connected to the rotating bolt 17, and the rotating bolt 17 can be driven directly by rotating the knob, which makes the operation simpler and more convenient.

[0041] Example 3 Example 3 is a preferred example. Fig. 9 As shown, the block 5 is a rectangular block, and its length on the left side of the vertical rod of the hook body 1 is greater than its length on the right side of the vertical rod of the hook body 1. It is used to balance the weight of the cross bar on the right side of the vertical rod, so that the hook is balanced as a whole to avoid imbalance and falling during installation.

[0042] Example 4 Example 4 is a preferred example. Fig.10 As shown, the block 5 is a rectangular block, and a counterweight block is arranged at the bottom of the left end thereof, which is used to balance the weight of the horizontal bar on the right side of the vertical bar, so that the hook is balanced as a whole and avoids imbalance and falling during installation. The addition of the counterweight block can shorten the length of the rectangular block, which helps to reduce the volume and weight of the entire hook device, making it lighter, more compact, and easy to carry and install.

[0043] Example 5 Example 5 is a preferred example. Fig.11 As shown, a limiting groove 23 is formed on the top of the block 5, and the limiting groove 23 cooperates with the groove 15 at the bottom of the horizontal section of the hook body 1 to limit the aluminum rod 2, and the upper and lower parts cooperate to limit the aluminum rod 2 to prevent the aluminum rod 2 from sliding and displacement, and the fixation is more stable.

[0044] Example 6 A grounding hook device method capable of hooking a grounding wire on the ground, the specific operation steps are as follows: (1) The auxiliary pull rope 12 is thrown over the aluminum rod 2 by hand, and the operator stands on the ground and pulls the auxiliary pull rope 12 by hand to pull the hook body 1 up; (2) Raise the hook body 1 and hang it on the aluminum rod 2. Pull the main pull rope 11 and the auxiliary pull rope 12 during the rise to ensure the balance of the hook body 1; (3) Pull the left pull rope 13 to move the right end of the clamping block 5 upward, and the clamping block 5 cooperates with the hook body 1 to fix the aluminum rod 2; (4) The locking pin 8 is lifted upward under the elastic force of the spring 9, and the locking pin 8 is lifted upward to lock the position of the block 5, thereby completing the installation of the hook body 1 and performing the insulation operation; (5) After the operation is completed, pull the right pull rope 14 to move the right side of the block 5 downward to unlock the aluminum rod 2; (6) Pull the main pull rope 11 to remove the hook body 1 from the aluminum rod 2.

[0045] As a preferred example of the above embodiment, it is faster and more convenient to use a drone to pass the auxiliary pull rope 12 over the aluminum rod 2. The drone can quickly and accurately place the auxiliary pull rope at a predetermined position with its flexible flying ability and precise positioning system, which facilitates the subsequent installation of the hook body.
