Description

Technical Field

[0001] This invention relates to the field of grounding rod technology, specifically to a grounding rod that is easy to pull out. Background Technology

[0002] Grounding pins are key components in grounding systems in fields such as power, communications, and construction. They are mainly used to conduct static electricity and fault currents from equipment or buildings to the ground, ensuring the normal operation of equipment and the safety of personnel. The ease of their installation and disassembly directly affects the efficiency and cost of grounding operations.

[0003] The existing grounding rod hammering device and return structure are mostly set up independently. The power generated by hammering is mostly unidirectional and cannot drive the rod to twist. In winter use, the bond between the frozen soil layer and the rod surface is difficult to break, resulting in greater resistance during the rod pulling process. The grounding rod connection mechanism often adopts threaded connection or simple snap-fit ​​method. Threaded connection is cumbersome to disassemble, and simple snap-fit ​​structure is prone to loosening during hammering and rod pulling, affecting the power transmission effect and making it difficult to adapt to the operation requirements of different scenarios. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a grounding rod that is easy to pull out, so as to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grounding rod that is easy to pull out, comprising: a hammering device, a locking mechanism, and a rod. The rod is connected to the hammering device via the locking mechanism. The hammering device includes a bracket that can rotate around its own axis. A disc is fixedly connected to both the upper and lower ends of the bracket, and a rotating gear is coaxially fixedly mounted on the upper surface of the top disc. A sliding sleeve is slidably connected to the outside of the bracket, and a handle is fixedly mounted on the outside of the sliding sleeve. Impact blocks are fixedly mounted at both the upper and lower ends of the sliding sleeve, and driving teeth are evenly arranged on the upper surface of the top impact block along the sliding direction of the sliding sleeve. The driving teeth mesh with the rotating gear. When the sliding sleeve slides up and down along the bracket, the driving teeth drive the rotating gear to periodically rotate in both directions, thereby transmitting the torsional force to the rod through the bracket fixedly connected to the locking mechanism, achieving shearing and loosening of the rod against the surrounding soil. Return devices are provided on both sides of the lower surface of the bottom impact block.

[0006] The return device includes a hinged base, a rotating seat rotatably mounted inside the hinged base, a hollow column rotatably mounted inside the rotating seat, and a sliding arm slidably connected to the inner cavity of the hollow column. The lower end of the sliding arm is fixedly connected to the upper surface of the bottom disc. A first elastic element is provided between the sliding arm and the hollow column. The first elastic element is a high-strength compression spring. When the sliding sleeve slides downward, the bottom impact block drives the hollow column to compress the sliding arm through the hinged base and the rotating seat, allowing the first elastic element to store elastic potential energy. When the sliding sleeve slides to the lowest point, the first elastic element releases the potential energy, generating an upward rebound force. This, combined with the impact force of the top impact block on the top disc when the sliding sleeve slides upward, forms a bidirectional superimposed pulling force. At the same time, the rotational cooperation between the rotating seat and the hinged base can adapt to the angular deviation during the sliding process of the sliding sleeve, ensuring the stable transmission of the elastic force of the first elastic element.

[0007] The locking mechanism includes a hollow sleeve. A top hollow assembly block is fixedly installed on the upper part of the inner cavity of the hollow sleeve, and a bottom hollow assembly block is fixedly installed on the upper outer wall of the drill rod. A locking tongue is rotatably installed in the inner cavity of the top hollow assembly block via a rotating shaft, and a control lever is fixedly installed on the outside of the locking tongue. A second elastic element, which is a torsion spring, is installed between the control lever and the top hollow assembly block. The second elastic element is sleeved on the rotating shaft of the locking tongue, with one end abutting against the control lever and the other end abutting against the inner wall of the top hollow assembly block. A locking block is fixedly installed on the outer wall of the bottom hollow assembly block corresponding to the position of the locking tongue. Both the hollow sleeve and the top hollow assembly block have openings along the edge. The axially extending slot allows the control lever to extend through the slot to the outside of the hollow sleeve. The second elastic element always provides locking force to the locking tongue, ensuring a tight engagement between the locking tongue and the locking block. This ensures a stable connection between the hollow sleeve and the drill rod through two hollow assembly blocks, preventing relative displacement during hammering and drill pulling. Simultaneously, the slot provides space for the swinging operation of the control lever. By moving the control lever, the locking tongue can be quickly unlocked, enabling rapid separation of the hammering equipment and the drill rod. The drill rod has an external grounding end, which is integrated with the drill rod to ensure stable grounding conductivity. Furthermore, the drill rod is detachably connected to the hammering equipment via a snap-fit ​​mechanism, adapting to grounding requirements in different scenarios.

[0008] Preferably, the handle is fitted with a rubber sleeve, and the rubber sleeve is uniformly provided with anti-slip texture. The rubber sleeve can not only increase the friction between the hand and the handle to avoid slipping during operation, but also buffer the vibration generated during the sliding of the sleeve, reducing the operator's fatigue. The uniform distribution of anti-slip texture further improves the grip stability and ensures the accurate transmission of hammering and chisel pulling actions.

[0009] Preferably, the inner cavity of the sliding sleeve and the inner cavities of the upper and lower impact blocks are coaxially provided with annular grooves. Ball bearings are rolled in the inner cavity of the annular grooves, and the balls are in contact with the outside of the bracket. The arrangement of the balls converts the sliding friction between the sliding sleeve, the impact blocks and the bracket into rolling friction, which greatly reduces the resistance when the sliding sleeve slides up and down, ensures smoother meshing and transmission between the drive teeth and the rotating gear, reduces component wear, and extends the service life of the equipment. The limiting effect of the annular grooves on the balls can prevent the balls from falling out and ensure the stability of transmission and sliding.

[0010] Preferably, the outer edge of the sliding sleeve and the tooth tips and sides of the drive teeth are all designed with uniform rounded corners, and the drive teeth are adapted to the inner cavity groove of the sliding sleeve. The rounded corner design can avoid the risk of sharp edge scratches during operation, improve the safety of use, and at the same time reduce stress concentration when the drive teeth mesh with the rotating gear, thus reducing tooth wear. The adaptation design between the drive teeth and the inner cavity groove of the sliding sleeve ensures the stability of the drive teeth installation, prevents them from loosening or shifting during hammering vibration, and ensures the reliability of torsional force transmission.

[0011] Preferably, the impact block has a curved groove on its exterior, and the curved groove is connected to the hinge seat by bolts. Magnets are installed in both the inner cavity of the curved groove and the exterior of the sliding arm, and the two sets of magnets attract each other. The curved groove design provides angle adjustment space for the installation of the hinge seat, allowing for fine-tuning of the installation angle of the return device according to actual assembly requirements, ensuring that the elastic force direction of the first elastic element is consistent with the sliding direction of the sliding sleeve. The attraction of the two sets of magnets assists the sliding arm in quickly resetting within the hollow column, while simultaneously enhancing the stability of the connection between the return device and the impact block, preventing the return device from shaking when the sliding sleeve slides at high speed.

[0012] Preferably, a stabilizing block is provided on the outside of the sliding arm, and a reinforcing block is provided on the outside of the stabilizing block. Fixing pins are provided between the hollow column and the rotating seat, and between the rotating seat and the hinge seat. The combined design of the stabilizing block and the reinforcing block enhances the structural strength of the sliding arm, preventing bending deformation during repeated compression and release of the first elastic element. The fixing pins can lock the relative rotation angle between the hollow column and the rotating seat, and between the rotating seat and the hinge seat, ensuring a stable force transmission path for the return device, while also facilitating disassembly and maintenance.

[0013] Preferably, the hollow assembly block is connected to the inner cavity of the hollow sleeve by bolts. A reinforcing plate is provided at the junction of the hollow assembly block and the hollow sleeve. The hollow sleeve is fixedly connected to the bracket. The bolt connection allows for a detachable connection between the hollow assembly block and the hollow sleeve, facilitating the replacement of hollow assembly blocks of different specifications to accommodate drill rods of different diameters. The reinforcing plate enhances the structural stability of the connection between the hollow assembly block and the hollow sleeve, dispersing the impact force generated during hammering and drill rod extraction, and preventing stress concentration at the junction that could lead to damage. The fixed connection between the hollow sleeve and the bracket ensures that the impact and torsional forces of the hammering equipment are fully transmitted to the drill rod, improving operational efficiency.

[0014] Preferably, the hollow sleeve is provided with a snap-fit ​​device on its outer side, and the drill rod is provided with a slot on its outer side that matches the snap-fit ​​device. The cooperation between the snap-fit ​​device and the slot enables secondary locking of the hollow sleeve and the drill rod, which further improves the connection reliability of the snap-fit ​​mechanism and avoids loosening during high-frequency hammering and torsional vibration. At the same time, the rotating snap-fit ​​device is easy to operate and can quickly complete the locking and unlocking actions.

[0015] Preferably, the bottom of the drill rod has evenly distributed plugs, and the outside of the drill rod is coated with a protective coating. The even distribution of the plugs reduces the resistance when the drill rod is driven into the ground, allowing the grounding end to quickly penetrate deep into the soil and improving grounding stability. The protective coating is made of corrosion-resistant and wear-resistant materials, which can effectively resist the erosion of moisture, salt, and other substances in the soil, extending the service life of the drill rod. At the same time, it reduces the adhesion between the soil and the drill rod surface, helping to improve the ease of drill rod extraction.

[0016] Preferably, the locking mechanism is uniformly provided with fixing bolts on its exterior, and the drill rod is provided with bolt fixing grooves that are compatible with the fixing bolts on its exterior. The cooperation between the fixing bolts and the bolt fixing grooves realizes the rigid fixation of the locking mechanism and the drill rod, further enhancing the connection stability and ensuring that the bidirectional impact force and torsional force generated by the hammering equipment can be efficiently transmitted to the drill rod, avoiding energy loss. At the same time, the bolt fixing method is easy to disassemble, facilitating the maintenance and replacement of parts of the equipment.

[0017] Compared with the prior art, the present invention provides a grounding rod that is easy to pull out, and has the following beneficial effects: This easily removable grounding rod, through the linkage of the hammering device and the return device, generates a bidirectional superimposed pulling force as the sliding sleeve slides, while also causing the rod to periodically rotate forward and backward. This shearing action breaks the bond between the soil and the rod, facilitating its removal. The locking mechanism securely connects the hammering device and the rod through the engagement of the locking tongue and locking block, ensuring efficient power transmission. Simultaneously, a control lever allows for quick unlocking and separation. Combined with its detachable design, it adapts to various grounding operation scenarios. The rotational cooperation between the rotating seat and the hinge seat in the return device accommodates angular deviations during the sliding of the sleeve, ensuring stable spring force transmission and improving operational smoothness.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] This invention provides a technical solution; please refer to [link / reference]. Figure 1 and Figure 2 A grounding rod that is easy to pull out includes: a hammering device 1, a clamping mechanism 3, and a rod 4. The rod 4 is connected to the hammering device 1 through the clamping mechanism 3. The hammering device 1 includes a bracket 11. Both the upper and lower ends of the bracket 11 are connected to discs 12. A rotating gear 13 is provided on the outside of the top disc 12. A sliding sleeve 14 is slidably connected to the outside of the bracket 11. A handle 17 is provided on the outside of the sliding sleeve 14. Both the upper and lower ends of the sliding sleeve 14 are provided with impact blocks 15. A drive tooth 16 is provided on the outside of the top impact block 15. The drive tooth 16 meshes with the rotating gear 13. When the sliding sleeve 14 slides up and down along the bracket 11, the drive tooth 16 will drive the rotating gear 13 to perform periodic forward and reverse rotation. Then, the torsional force is transmitted to the clamping mechanism 3 and the rod 4 through the bracket 11, so as to achieve shearing and loosening of the rod 4 with the surrounding soil. Return devices 2 are provided on both sides of the bottom impact block 15.

[0022] The return device 2 includes a hinge seat 21, a rotating seat 22 rotatably mounted inside the hinge seat 21, a hollow column 23 rotatably mounted inside the rotating seat 22, and a sliding arm 25 slidably connected inside the hollow column 23. A first elastic element 24 is provided between the sliding arm 25 and the hollow column 23. The first elastic element 24 is a high-strength compression spring. When the sliding sleeve 14 slides downward, the bottom impact block 15 will drive the hollow column 23 to compress the sliding arm 25 through the hinge seat 21 and the rotating seat 22, so that the first elastic element 24 stores elastic potential energy. When the sliding sleeve 14 slides to the lowest point, the first elastic element 24 releases potential energy and generates an upward rebound force. Combined with the impact force of the top impact block 15 on the top disc 12 when the sliding sleeve 14 slides upward, a bidirectional superimposed pulling force is formed. At the same time, the rotational cooperation between the rotating seat 22 and the hinge seat 21 can adapt to the angular deviation during the sliding process of the sliding sleeve 14, ensuring the stable transmission of the elastic force of the first elastic element 24.

[0023] Please see Figure 3 and Figure 4 The locking mechanism 3 includes a hollow sleeve 31. Hollow assembly blocks 32 are provided both inside the hollow sleeve 31 and outside the drill rod 4. A locking tongue 33 is rotatably mounted inside the hollow assembly block 32, and a control lever 34 is provided outside the locking tongue 33. A second elastic element 35 is provided between the control lever 34 and the hollow assembly block 32. A locking block 37 is provided outside the hollow assembly block 32. Slots 36 are provided on the outer surfaces of both the hollow sleeve 31 and the top hollow assembly block 32. The second elastic element 35 always provides locking force to the locking tongue 33, causing the locking tongue 33 to engage with the locking block 37. The tight engagement ensures a secure connection between the hollow sleeve 31 and the drill rod 4 via the hollow assembly block 32, preventing relative displacement during hammering and drill pulling. Simultaneously, the slot 36 provides space for the operation of the control lever 34. By moving the control lever 34, the locking tongue 33 can be quickly unlocked, enabling rapid separation of the hammering device 1 from the drill rod 4. The drill rod 4 has an external grounding terminal 41, which is integrated with the drill rod 4 to ensure stable grounding conductivity. Furthermore, the drill rod 4 is detachably connected to the hammering device 1 via the locking mechanism 3, adapting to grounding requirements in different scenarios.

[0024] Please see Figure 4 and Figure 5 The handle 17 is fitted with a rubber sleeve, and the rubber sleeve is evenly textured with anti-slip texture. The rubber sleeve can not only increase the friction between the hand and the handle 17 to prevent slipping during operation, but also buffer the vibration generated during the sliding of the sliding sleeve 14, reducing the operator's fatigue. The even distribution of anti-slip texture further improves the grip stability and ensures the accurate transmission of hammering and chisel pulling actions.

[0025] Both the impact block 15 and the sliding sleeve 14 have annular grooves in their inner cavities. The inner cavities of the annular grooves are equipped with balls, which are in contact with the outside of the bracket 11. The arrangement of the balls converts the sliding friction between the sliding sleeve 14, the impact block 15 and the bracket 11 into rolling friction, which greatly reduces the resistance when the sliding sleeve 14 slides up and down. This ensures smoother meshing and transmission between the drive teeth 16 and the rotating gear 13, while also reducing component wear and extending the service life of the equipment. The limiting effect of the annular grooves on the balls can prevent the balls from falling out and ensure the stability of transmission and sliding.

[0026] The sliding sleeve 14 and the drive gear 16 feature uniformly rounded corners on their outer surfaces, and the drive gear 16 is fitted with the inner cavity groove of the sliding sleeve 14. This rounded corner design avoids the risk of sharp edges causing scratches during operation, improving safety. It also reduces stress concentration when the drive gear 16 meshes with the rotating gear 13, reducing tooth wear. The fitted design between the drive gear and the inner cavity groove of the sliding sleeve ensures the stable installation of the drive gear 16, preventing loosening or displacement during hammering vibration and guaranteeing the reliability of torsional force transmission.

[0027] The impact block 15 has a curved groove on its exterior, which is connected to the hinge seat 21 by bolts. Magnets are installed in both the inner cavity of the curved groove and the exterior of the sliding arm 25, and the two sets of magnets attract each other. The curved groove design provides angle adjustment space for the installation of the hinge seat 21, allowing for fine-tuning of the installation angle of the return device 2 according to actual assembly requirements, ensuring that the elastic force direction of the first elastic element 24 is consistent with the sliding direction of the sliding sleeve 14. The attraction of the two sets of magnets assists the sliding arm 25 in quickly resetting within the hollow column 23, while simultaneously enhancing the stability of the connection between the return device 2 and the impact block 15, preventing the return device 2 from shaking when the sliding sleeve 14 slides at high speed.

[0028] A stabilizing block 26 is provided on the outside of the sliding arm 25, and a reinforcing block is provided on the outside of the stabilizing block 26. Fixing pins are provided between the hollow column 23 and the rotating seat 22, and between the rotating seat 22 and the hinge seat 21. The combined design of the stabilizing block 26 and the reinforcing block enhances the structural strength of the sliding arm 25, preventing bending deformation during repeated compression and release of the first elastic element 24. The fixing pins can lock the relative rotation angle between the hollow column 23 and the rotating seat 22, and between the rotating seat 22 and the hinge seat 21, ensuring a stable force transmission path for the return device 2, while also facilitating disassembly and maintenance.

[0029] The hollow assembly block 32 is connected to the inner cavity of the hollow sleeve 31 by bolts. A reinforcing plate is provided at the junction of the hollow assembly block 32 and the hollow sleeve 31. The hollow sleeve 31 is fixedly connected to the bracket 11. The bolt connection allows for a detachable connection between the hollow assembly block 32 and the hollow sleeve 31, facilitating the replacement of hollow assembly blocks 32 of different specifications to accommodate drill rods 4 of different diameters. The reinforcing plate enhances the structural stability of the connection between the hollow assembly block 32 and the hollow sleeve 31, dispersing the impact force generated during hammering and drill pulling, and preventing stress concentration at the junction that could lead to damage. The fixed connection between the hollow sleeve 31 and the bracket 11 ensures that the impact and torsional forces of the hammering device 1 are fully transmitted to the drill rod 4, improving operational efficiency.

[0030] The hollow sleeve 31 is externally equipped with a snap-fit ​​device, and the drill rod 4 is externally equipped with a slot that matches the snap-fit ​​device. The cooperation between the snap-fit ​​device and the slot enables the hollow sleeve 31 and the drill rod 4 to be locked together again, which further improves the connection reliability of the snap-fit ​​mechanism 3 and prevents loosening during high-frequency hammering and torsional vibration. At the same time, the rotating snap-fit ​​device is easy to operate and can quickly complete the locking and unlocking actions.

[0031] The bottom of the drill rod 4 is evenly provided with plugs 42, and the outside of the drill rod 4 is covered with a protective coating. The even distribution of the plugs 42 reduces the resistance when the drill rod 4 is driven into the ground, allowing the grounding end 41 to be quickly inserted into the soil and improving grounding stability. The protective coating is made of corrosion-resistant and wear-resistant materials, which can effectively resist the erosion of moisture, salt and other substances in the soil, extend the service life of the drill rod 4, and at the same time reduce the adhesion between the soil and the surface of the drill rod 4, thus helping to improve the ease of drill rod extraction.

[0032] The snap-fit ​​mechanism 3 is uniformly provided with fixing bolts 43 on its outside, and the drill rod 4 is provided with bolt fixing grooves that are compatible with the fixing bolts 43 on its outside. The cooperation between the fixing bolts 43 and the bolt fixing grooves realizes the rigid fixation between the snap-fit ​​mechanism 3 and the drill rod 4, which further enhances the connection stability and ensures that the bidirectional impact force and torsional force generated by the hammering device 1 can be efficiently transmitted to the drill rod 4, avoiding energy loss. At the same time, the bolt fixing method is easy to disassemble, which facilitates the maintenance and replacement of parts of the equipment.
