Description

Technical Field

[0001] This invention relates to the field of grounding electrode construction technology, and in particular to a portable grounding electrode drilling and installation tool and a grounding electrode construction method. Background Technology

[0002] During the construction of railways, it is often necessary to pre-bury grounding electrodes. However, in some areas with complex terrain, significant elevation differences, a high proportion of bridges and tunnels, or where electrification stations are located in valleys, hills, or mountain valleys, the surface layer is mostly composed of composite geology such as rock layers, gravel soil, boulders, and artificial fill, which brings great difficulties to the construction work of civil engineering and electrical engineering professionals, especially the installation of grounding electrodes.

[0003] Traditional grounding electrode construction methods mainly include manual excavation and backfilling, mechanical excavation and backfilling, hammering, and casing-protected hammering. Manual backfilling is generally used in locations where machinery cannot be used, such as existing line renovation sites or confined spaces. Mechanical excavation and backfilling uses excavators to excavate the earth, bury the grounding electrode, and then backfill and compact the soil. Its advantages are labor saving, fast construction speed, and less susceptibility to geological limitations; its disadvantages include a large operating range, lower installation quality, and the grounding electrode being prone to tilting or bending during backfilling. The hammering method has strict geological requirements, requiring soft soil for construction. The existing grounding electrode installation method requires highly skilled personnel and carries significant safety risks, easily damaging the grounding electrode. The sleeve-protected hammer method uses an additional steel pipe to protect the grounding electrode before hammering it in with an electric hammer. Its advantage is higher installation quality; however, it is greatly affected by geological conditions, has greater instability, and the steel pipe may become impossible to remove. It is suitable for specific situations. These factors mean that the existing grounding electrode installation method cannot meet the installation quality and schedule requirements under these geological conditions. Therefore, researching a new portable grounding electrode drilling and installation tool and grounding electrode construction method to solve these problems is of great significance.

[0019] A method for constructing a grounding electrode, the method comprising the following steps:

[0020] S1. Determine the hole diameter and depth based on the grounding electrode size. The hole diameter should be 2mm larger than the grounding electrode diameter. The drilling depth should be consistent with the grounding electrode length. Generally, the grounding electrode size is designed as Ф18*3000mm, therefore the drilling size is Ф20*3000mm. Then, control the first motor to drive the lead screw to rotate, which in turn drives the nut downwards, causing the nut to drive the movable plate downwards, thus moving the detachable drilling assembly downwards. Next, control the second motor to drive the auger drill rod to rotate through the connecting assembly, allowing the auger drill rod to smoothly drill into the ground. Since the auger drill rod is 1m long, when the drilling reaches this depth, remove the magnetic block and align it with the magnet. The magnetic repulsion between the block and the magnet causes the magnetic block to control the magnet to retract into the notch, and then control the first motor to move in the opposite direction, causing the lead screw to drive the nut to move upward, causing the second motor to separate from the auger drill rod and remove the connecting drill rod, so that the bottom of the connecting drill rod is inserted into the groove of the auger drill rod, and the elastic force of the second spring pushes the magnet to return to its original position, so that the magnet is located between the fixed opening and the notch. At the same time, the top of the connecting drill rod is connected to the second motor in the same way. Then, the first motor is controlled to rotate forward, and the second motor controls the connecting drill rod to drive the auger drill rod to rotate, so that it continues to drill into the ground for drilling operations until the connecting drill rod drills into the ground, and then another connecting drill rod is connected to continue drilling operations deeper into the ground.

[0021] S2. When the drill bit gets stuck and the auger rod cannot drill down, the first motor continues to drive the screw to rotate, and the nut continues to control the moving plate to move downward. Because the fixed plate cannot move down due to the stuck drill bit, the moving plate compresses the first spring through the movable sleeve, which causes the connecting plate to drive the rack downward and mesh with the gear. The gear drives the rotating shaft to rotate, which in turn drives the roller to move in the frame. The frame drives the second motor to move up and down, which in turn drives the auger rod to move up and down, which is conducive to breaking through the hard layer and drilling down.

[0022] S3. During the up-and-down movement of the second motor, the second motor drives the piston rod to move up and down. When the piston rod moves upward, the one-way valve opens to guide the liquid into the lower part of the water cylinder. When the piston rod moves downward, the liquid enters the annular shell through the hose, and then enters the water outlet through the inlet and support block. Finally, it is discharged through the drain outlet near the bottom of the auger rod. The water flow facilitates the drilling operation of the auger rod. After drilling is completed, the auger rod is taken out and the grounding electrode is placed into the borehole.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: The portable grounding electrode drilling and installation tool and grounding electrode construction method can automatically control the detachable drilling component to perform self-tapping drilling operations through the self-tapping component. At the same time, when changing the drill rod after each 1m drilling operation, there is no need to remove the auger drill rod for replacement, which prevents tilting or hole collapse and the entry of surface impurities into the borehole, affecting the next drilling operation. This method can be quickly assembled and used by simply connecting the components. When the drill gets stuck, the cooperation between the self-tapping component and the elastic component can drive the detachable drilling component to move up and down, which is conducive to breaking through hard layers and facilitating drilling. Moreover, the water diversion component diverts water through the bottom of the detachable drilling component, which reduces the drilling resistance and makes it easier to drill through hard layers. This construction method is no longer a matter of excavation and hammering, adaptable to various complex geological conditions, and can improve the installation quality. Attached Figure Description

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention.

[0039] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0040] Example 1

[0041] like Figure 1-3 and Figure 10 As shown, the present invention provides a technical solution: a portable grounding electrode drilling and installation tool, comprising,

[0042] The transfer mechanism 1 includes an alarm light 11, a moving assembly 12, two connecting drill rods 13, two clamps 14, a magnetic plate 15, and two magnetic blocks 16 magnetically attracted to the magnetic plate 15. The magnetic plate 15 and the magnetic blocks 16 are attracted to each other, so that the position of the magnetic blocks 16 can be fixed. At the same time, the magnetic blocks 16 correspond to the magnet 281. Since the magnet 281 and the magnetic blocks 16 are magnetically repelled, the magnetic blocks 16 can push the magnet 281 to overcome the elastic force of the second spring 282 and retract into the notch, thereby facilitating the quick removal of the spiral drill rod 232. The alarm light 11 is installed on the top of the moving assembly 12, and the magnetic plate 15 is embedded in the moving assembly 12. The moving assembly 12 includes a base plate 121, and the base plate 121 has four... Each corner is fixedly connected with a caster wheel 123. A vertical plate 122 is fixedly connected to the upper surface of the base plate 121. Two clamps 14 are fixedly connected to both sides of the vertical plate 122. A magnetic plate 15 is embedded in the vertical plate 122. A handrail 124 is fixedly connected to one end of the vertical plate 122. The handrail 124 provides a support point, and the caster wheels 123 assist in movement, making the device easy to move and saving time and effort. An alarm light 11 is installed on the top of the vertical plate 122, and two clamps 14 are fixedly connected to both sides of the moving assembly 12. Two connecting drill rods 13 are respectively engaged in the two clamps 14. The clamps 14 can fix the position of the connecting drill rods 13 and prevent them from falling off.

[0043] The automatic oscillating drilling mechanism 2 includes a self-tapping component 24, an elastic component 22, a detachable drilling component 23, a water-guiding component 26, four toothed rods 211, a frame 27, and two transmission components 25 slidably connected in the frame 27. The two transmission components 25 are respectively meshed with the two left and two right toothed rods 211. The four toothed rods 211 are fixedly connected to the elastic component 22, which is connected to the self-tapping component 24 and the moving component 12. The self-tapping component 24 includes a first motor 241, with brackets 242 fixedly connected to both sides of the first motor 241. The brackets 242 can support the first motor 241. For the purpose of fixing, the output shaft of the first motor 241 is fixedly connected to the lead screw 243, and the bottom end of the lead screw 243 is rotatably connected to the base plate 121 through the bearing. The external thread of the lead screw 243 is fitted with a nut 244. The first motor 241 controls the thread transmission between the lead screw 243 and the nut 244, which can realize the automatic self-tapping drilling operation of the detachable drilling assembly 23. The water diversion assembly 26 is fixedly connected to the elastic assembly 22, and the bottom end of the water diversion assembly 26 is fixedly connected to the detachable drilling assembly 23. The detachable drilling assembly 23 is installed in the middle of the frame 27, and the bottom end of the water diversion assembly 26 is connected to the detachable drilling assembly 23.

[0044] The detachable drilling assembly 23 includes a spiral drill rod 232 and a second motor 231. Water inlets 213 are provided in both the connecting drill rod 13 and the spiral drill rod 232. Grooves 29 are provided at the top of both the connecting drill rod 13 and the top of the spiral drill rod 232. The grooves 29 ensure the smooth insertion of the support block 283, allowing the magnet 281 to align with the fixing port 210. Fixing ports 210 are provided on both side walls of the groove 29. A connecting assembly 28 is fixedly connected to the bottom of the output shaft of the second motor 231 and the bottom of the connecting drill rod 13. The connecting assembly 28 includes support blocks 283. Two support blocks 283 are fixedly connected to the bottom of the second motor 231 and the connecting drill rod 13, respectively. Recesses are provided on both sides of the support blocks 283, and a second spring 282 is fixedly connected to the side wall of each recess. A magnet 281 is fixedly connected to one end of the second spring 282. The elastic force of the second spring 282... The magnet 281 can be reset, so that it is located between the notch and the fixing port 210, which can facilitate the quick assembly connection of the drill rod 13 and the spiral drill rod 232, improving construction efficiency. The magnet 281 is sized to match the notch and the fixing port 210. The support block 283 is hollow. The water inlet 212 is connected to the water outlet 213 through the support block 283. The hollowness of the support block 283 can facilitate the connection between the water inlet 212 and the water outlet 213, allowing the liquid to be smoothly introduced into the drain port 233. One of the connecting components 28 is built into the groove 29 of the spiral drill rod 232. The second motor 231 is fixedly connected to the middle of the frame 27. The bottom of the spiral drill rod 232 has multiple drain ports 233, which can ensure that the liquid is smoothly discharged from the spiral drill rod 232. The spiral drill rod 232 is connected to the output shaft of the second motor 231.

[0045] In this embodiment, the first motor 241 drives the lead screw 243 to rotate, causing the lead screw 243 and nut 244 to drive the movable plate 223 to move downwards. This causes the elastic component 22 to drive the detachable drilling component 23 to move downwards, and then the second motor 231 controls the spiral drill rod 232 to move downwards, causing the spiral drill rod 232 to screw into the soil, thereby realizing self-tapping drilling operation, making the drilling operation more labor-saving. When the spiral drill rod 232 reaches a depth of 1m, the magnetic block 16 is aligned with the magnet 281, so that the magnetic block 16 and the magnet 281 repel each other, causing the magnet 281 to retract into the notch. Then, through the first... The motor 241 moves in the reverse direction, causing the lead screw 243 to lift the nut 244, thus separating the second motor 231 from the auger drill rod 232. Then, the connecting drill rod 13 aligns with the support block 283 and the auger drill rod 232. At the same time, the elastic force of the second spring 282 drives the magnet 281 to be located between the notch and the fixing port 210, so that the connecting drill rod 13 connects the auger drill rod 232 and the output shaft of the second motor 231. In this way, the self-tapping drilling operation can continue. This method does not require the auger drill rod 232 to be removed and replaced, which prevents it from tilting or collapsing when it is removed and reinserted into the hole, and prevents surface impurities from entering the hole and affecting the next drilling operation.

[0046] Example 2

[0047] Combined with appendix Figure 4 and attached Figure 8-9 It is concluded that: the elastic component 22 includes a movable plate 223 and a fixed plate 224. A switch 21 is fixedly installed on the upper surface of the fixed plate 224. The fixed plate 224 is sleeved outside the lead screw 243. The movable plate 223 is fixedly connected to the outside of the nut 244. The upper part of the lead screw 243 is rotatably connected to the U-shaped guide rod 226 through a bearing. Two brackets 242 are installed on the guide rod 226. The guide rod 226 is fixedly connected to the base plate 121. Two movable sleeves 222 are fixedly connected to both the fixed plate 224 and the movable plate 223. All four movable sleeves 222 are slidably connected to the guide rod 224. 6. The guide rod 226 can guide the movable sleeve 222, so that the movable sleeve 222 can slide smoothly on the guide rod 226, so that the movable plate 223 and the fixed plate 224 can move smoothly. A first spring 221 is fixedly connected between the two movable sleeves 222. The first spring 221 can support the movable plate 223, and after the stuck drill is eliminated, the elastic force of the first spring 221 can drive the movable plate 223 to return to its original position smoothly. Two connecting plates 225 are fixedly connected to one side of the movable plate 223. The lower surface of the connecting plate 225 is fixedly connected to two toothed rods 211.

[0048] The transmission assembly 25 includes two connecting bars 252, and a roller 251 is fixedly connected between the two connecting bars 252. The roller 251 is slidably connected in the frame 27. The opening of the frame 27 can ensure that the roller 251 can move, and at the same time, the roller 251 can drive the frame 27 to reciprocate. A rotating shaft 254 is fixedly connected to one side of the connecting bar 252. The rotating shaft 254 is rotatably connected to the fixed block 253 through a bearing. The fixed block 253 is fixedly connected to the fixed plate 224. A gear 255 is fixedly connected to one end of the rotating shaft 254. The gear 255 meshes with the rack 211.

[0049] In this embodiment: the self-tapping component 24 continuously applies force to the movable plate 223. Due to the stuck drill, the fixed plate 224 is fixed in position. At this time, the movable plate 223 compresses the first spring 221 and moves downward, causing the rack 211 to mesh downward with the gear 255. The gear drives the roller 251 to rotate through the rotating shaft 254, causing the roller 251 to slide in the frame 27 and drive the frame 27 to move up and down. The frame 27 drives the second motor 231 to move up and down, and the second motor 231 drives the spiral drill rod 232 to move up and down. The spiral drill rod 232 can easily break through the hard layer, which facilitates the drilling operation. Moreover, when the drill is stuck, the hard layer can be automatically drilled through without removing the spiral drill rod 232, which speeds up the construction process and facilitates the construction operation.

[0050] Secondly, when the movable plate 223 continues to move downward and the switch 21 is pressed down, the switch 21 controls the alarm light 11 to sound an alarm, thereby reminding the construction personnel to take action and avoid delaying the construction progress when the drill is stuck.

[0051] Example 3

[0052] Combined with appendix Figure 5-7Therefore, the water intake assembly 26 includes a water cylinder 261, which can store liquid. The top of the water cylinder 261 has a water inlet for easy water filling. The water cylinder 261 is mounted on the movable plate 223. Inside the water cylinder 261 is a piston rod 264, which has a one-way valve 263. The one-way valve 263 ensures one-way liquid flow, preventing backflow. The bottom end of the piston rod 264 is fixedly connected to the second motor 231. A sealing sleeve 265 passes through the piston rod 264, ensuring the sealing performance of the piston rod and preventing leakage. The sealing sleeve 265 is fixedly connected to the bottom of the water cylinder 261. A flexible hose 262 is connected to one side of the water cylinder 261. The flexible hose 262 can connect the annular shell 266 and the water cylinder 261. Moreover, the flexible hose 262 is elastic, which allows the detachable drilling assembly 23 to move up and down smoothly. The bottom end of the flexible hose 262 is connected to the annular shell 266. The output shaft of the second motor 231 is rotatably connected to the annular shell 266 through two bearings. The annular shell 266 is fixedly connected to the second motor 231 through a connecting rod. A water inlet 212 is provided on the output shaft of the second motor 231.

[0053] In this embodiment: the first motor 241 drives the piston rod 264 to move up and down reciprocally, so that when the piston rod 264 moves upward, the one-way valve 263 opens, allowing the liquid above the water cylinder 261 to enter the lower part. When the piston rod 264 moves downward, the one-way valve 263 closes, allowing the liquid to be forced into the annular shell 266 through the hose 262, and then enter the water outlet 213 through the hollow of the inlet 212 and the support block 283, allowing the liquid to be discharged through the drain outlet 233. This reduces the resistance of the water flow and provides good lubrication, making it easier to drill through the hard layer. This greatly meets the actual construction schedule, reduces the construction difficulty, and improves the installation quality of the grounding electrode.

[0054] A grounding electrode construction method, comprising the following steps:

[0055] S1. Determine the hole diameter and depth based on the grounding electrode size. The hole diameter should be 2mm larger than the grounding electrode diameter. The drilling depth should be consistent with the grounding electrode length. Generally, the grounding electrode size is designed as Ф18*3000mm, so the drilling size is Ф20*3000mm. Then, control the first motor 241 to drive the lead screw 243 to rotate, which in turn drives the nut 244 to move downwards. This causes the nut 244 to drive the movable plate 223 to move downwards, thus moving the detachable drilling assembly 23 downwards. Then, control the second motor 231 to drive the auger drill rod 232 to rotate through the connecting assembly 28, allowing the auger drill rod 232 to smoothly drill into the ground. Since the length of the auger drill rod 232 is 1m, when the drilling reaches this depth, remove the magnetic block 16 and align it with the magnet 281. Magnetic repulsion causes the magnetic block 16 to control the magnet 281 to retract into the notch, and then controls the first motor 241 to move in the opposite direction, causing the lead screw 243 to drive the nut 244 to move upward, causing the second motor 231 to separate from the auger drill rod 232, and the connecting drill rod 13 to be removed, so that the bottom of the connecting drill rod 13 is inserted into the groove 29 of the auger drill rod 232, and the elastic force of the second spring 282 pushes the magnet 281 to return to its original position, so that the magnet 281 is located between the fixed opening 210 and the notch. At the same time, the top of the connecting drill rod 13 is connected to the second motor 231 in the same way. Then, the first motor 241 is controlled to rotate forward, and the second motor 231 controls the connecting drill rod 13 to drive the auger drill rod 232 to rotate, so that it continues to drill into the ground for drilling operations until the connecting drill rod 13 drills into the ground, and then another connecting drill rod 13 is connected to continue drilling operations deeper into the ground.

[0056] S2. When the drill bit gets stuck and the auger rod 232 cannot drill down, the first motor 241 continues to drive the lead screw 243 to rotate, and the nut 244 continues to control the movable plate 223 to move downward. Because the drill bit is stuck, the fixed plate 224 cannot move down. At this time, the movable plate 223 compresses the first spring 221 through the movable sleeve 222, which causes the connecting plate 225 to drive the rack 211 to mesh with the gear 255 downward. The gear 255 drives the rotating shaft 254 to rotate, which causes the rotating shaft 254 to drive the roller 251 to move in the frame 27. The frame 27 drives the second motor 231 to move up and down, which in turn drives the auger rod 232 to move up and down, which is conducive to breaking through the hard layer and drilling down.

[0057] S3. During the up-and-down movement of the second motor 231, the second motor 231 drives the piston rod 264 to move up and down. When the piston rod 264 moves upward, the one-way valve 263 opens to guide the liquid into the lower part of the water cylinder 261. When the piston rod 264 moves downward, the liquid enters the annular shell 266 through the hose 262, and enters the water outlet (213) through the inlet 212 and the support block 283. Then it is discharged through the drain outlet 233 near the bottom of the spiral drill rod 232. Under the action of the water flow, it is beneficial for the spiral drill rod 232 to drill down. After the drilling is completed, the spiral drill rod 232 is taken out and the grounding electrode is placed into the borehole.

7. A method for constructing a grounding electrode, comprising a portable grounding electrode drilling and installation tool according to claim 6, characterized in that: The construction method includes the following steps: S1. Determine the hole diameter and depth according to the grounding electrode size. The hole diameter is required to be 2mm larger than the grounding electrode diameter. The drilling depth is consistent with the grounding electrode length. The grounding electrode size is designed as Ф18*3000mm, so the drilling size is Ф20*3000mm. Then control the first motor (241) to run, so that the first motor (241) drives the lead screw (243) to rotate, so that the lead screw (243) drives the nut (244) to move downward, so that the nut (244) drives the movable plate (223) to move downward. The detachable drilling assembly (23) moves downward, causing the second motor (231) to rotate the auger rod (232) via the connecting assembly (28), allowing the auger rod (232) to smoothly drill into the soil. Since the length of the auger rod (232) is 1m, when the drilling reaches this depth, the magnetic block (16) is removed and its position is aligned with that of the magnet (281). Due to the magnetic repulsion between the magnetic block (16) and the magnet (281), the magnetic block (16) and the magnet (281) are aligned. The magnetic block (16) controls the magnet (281) to retract into the notch, and then controls the first motor (241) to move in the opposite direction, causing the lead screw (243) to drive the nut (244) to move upward, causing the second motor (231) to separate from the auger rod (232), and removing the connecting rod (13), so that the bottom of the connecting rod (13) is inserted into the groove (29) of the auger rod (232), so that the elastic force of the second spring (282) pushes the magnet (281) to reset, so that the magnet ( 281) Located between the fixed opening (210) and the notch, the top of the connecting drill rod (13) is connected to the second motor (231) in the same way. Then, the first motor (241) is controlled to rotate forward, while the second motor (231) controls the connecting drill rod (13) to drive the spiral drill rod (232) to rotate, so that it continues to drill into the ground for drilling operations until the connecting drill rod (13) drills into the ground. Then, another connecting drill rod (13) is connected to continue drilling operations into the ground. S2. When the drill bit gets stuck and the auger rod (232) cannot drill down, the first motor (241) continues to drive the screw (243) to rotate, and the nut (244) continues to control the moving plate (223) to move downward. Because the drill bit gets stuck, the fixed plate (224) cannot move down. At this time, the moving plate (223) compresses the first spring (221) through the moving sleeve (222), so that the connecting plate (225) drives the rack (211) to mesh with the gear (255) downward, so that the gear (255) drives the rotating shaft (254) to rotate, so that the rotating shaft (254) drives the roller (251) to move in the frame (27), so that the frame (27) drives the second motor (231) to move up and down, so that the second motor (231) drives the auger rod (232) to move up and down, which is conducive to breaking through the hard layer and drilling down. S3. During the up-and-down movement of the second motor (231), the second motor (231) drives the piston rod (264) to move up and down. When the piston rod (264) moves upward, the one-way valve (263) opens to guide the liquid into the lower part of the water cylinder (261). When the piston rod (264) moves downward, the liquid enters the annular shell (266) through the hose (262), and enters the water outlet (213) through the inlet (212) and the support block (283). Then it is discharged through the drain outlet (233) near the bottom of the auger rod (232). Under the action of the water flow, it is beneficial for the auger rod (232) to drill down. After the drilling is completed, the auger rod (232) is taken out and the grounding electrode is placed into the borehole.
