[0018] In order to make the objectives, technical solutions and beneficial effects of the present invention more clear, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0019] like Figures 1 to 4 As shown, the present invention provides a stable grounding rod installation and positioning bracket, including a grounding rod and a horizontally arranged base 4, a clamping plate 3 arranged parallel to the base 4 is installed on the top surface of the base 4, the clamping plate 3 is a shell structure with a cavity, and a clamping device 1 is installed in the clamping plate 3, the grounding rod 7 is vertically arranged, and the grounding rod 7 passes through the clamping plate 3, the clamping device 1 and the base 4 in sequence. Specifically, when in use, the base 4 is fixed at the position where the grounding rod 7 needs to be installed, and the base 4 is in a horizontal state, and then after the grounding rod 7 passes through the clamping plate 3, the clamping device 1 and the base 4 in sequence, the position of the grounding rod 7 can be preliminarily located, and at this time, the bottom end of the grounding rod 7 abuts the ground.

[0020] The specific setting method of the clamping device 1 is as follows: the clamping device 1 includes two rotatable gears 11 located in the clamping disk 3, the two gears 11 are arranged vertically opposite to each other, and a horizontally distributed tooth plate 12 is meshed between the two gears 11, that is, the two sides of the tooth plate 12 are respectively meshed with the gears 11; the tooth plate 12 is opposite to the grounding rod 7, and a clamp 13 is installed at one end of the tooth plate 12 close to the grounding rod 7, and the other end of the tooth plate 12 is rotatably connected to a horizontally arranged threaded rod 14, the threaded rod 14 passes through the clamping disk 3 and is threadedly connected to the clamping disk 3. Specifically, when in use, the threaded rod 14 can be rotated to drive the tooth plate 12 to move in the horizontal direction, and the tooth plate 12 can make the clamp 13 away from or close to the grounding rod 7 during the movement.

[0021] In addition, each gear 11 is meshed with a horizontally arranged rack 15 on one side away from the tooth plate 12. The two racks 15 are located on both sides of the tooth plate 12 and are cross-arranged up and down. Specifically, the height of the tooth plate 12 is located between the two racks 15, and the position of the tooth plate 12 and the position of the rack 15 do not affect each other; one end of each rack 15 passes through the clamping plate 3 and is slidably connected to the clamping plate 3, and the other end of the rack 15 is fixedly connected to a clamping rod 16 arranged parallel to the rack 15, and the clamping rod 16 is respectively located outside the grounding rod 7, and the ends of the clamping rod 16 away from the rack 15 are bent inwardly into a hook shape. Specifically, when in use, when the tooth plate 12 is in the process of horizontal movement, it can drive the two gears 11 to rotate synchronously, so as to drive the two racks 15 to move horizontally synchronously, so that the hook-shaped position of the clamping rod 16 and the clamp 13 can be simultaneously away from or close to the grounding rod 7, and when the clamp 13 of the clamping device 1 and the two clamping rods 16 are from different directions After they are in contact with the ground rod 7 together, that is, when the clamping device 1 clamps and positions the ground rod 7, the ground rod 7 can be in a vertical state. In addition, by rotating the threaded rod 14 as a drive, not only can the ground rod 7 be clamped accurately, but also the clamping force can be uniform, and it is convenient to adjust the clamping force of the clamping device 1 on the ground rod 7, so that after the clamp 13 and the two clamping rods 16 are in contact with the ground rod 7 from different directions, it does not affect the insertion of the ground rod 7 into the ground under the action of external force. In this way, in the process of nailing the ground rod 7 into the ground, there is no need to hold the ground rod 7 by hand, so that on the one hand, it can avoid the occurrence of hand shaking and hand injury, so as to reduce the accident rate in the installation process; on the other hand, it can ensure that the ground rod 7 is nailed vertically into the ground, that is, the verticality of the installation of the ground rod 7 can be ensured, so as to improve the installation quality; secondly, since the hook-shaped positions of the clamp 13 and the two clamping rods 16 can be far away from or close to the ground rod 7, the clamping device 1 can also clamp and position ground rods 7 of different diameters.

[0022] In order to facilitate the measurement of the depth of the ground rod 7 inserted into the ground to avoid the situation of insufficient burial depth, Figure 1 and Figure 4As shown, a depth measuring device 2 is installed on the top surface of the clamping disk 3, and the depth measuring device 2 includes a sleeve 21 sleeved on the grounding rod 7, the sleeve 21 is installed on the clamping disk 3, and one side of the sleeve 21 is fixedly connected to a fixed seat 22 horizontally installed on the clamping disk 3, the fixed seat 22 is a shell structure with a cavity, and a roller 23 capable of abutting against the grounding rod 7 is rotatably connected in the fixed seat 22, the roller 23 is horizontally arranged, and an encoder is installed on the roller 23, and the encoder is electrically connected to a controller 24 with a control screen, specifically, the controller 24 is a PLC controller in the prior art, and the encoder is a rotary encoder; when the grounding rod 7 is installed, that is, the grounding rod 7 is in the process of descending, the roller 23 abutting against the grounding rod 7 can roll with the downward movement of the grounding rod 7, and then under the action of the encoder, the depth of the grounding rod 7 inserted into the ground can be measured, and the measurement signal can be displayed in real time through the control screen, so as to directly observe the depth of the grounding rod 7 inserted into the ground, thereby avoiding the situation that the grounding rod 7 is not buried deep enough to ensure the grounding effect.

[0023] The specific configuration method of the roller 23 being able to abut against the grounding rod 7 is as follows: Figure 4 As shown, the top surface of the fixing seat 22 is opened, and a slider 25 is slidably connected inside the fixing seat 22. The roller 23 is installed on the side of the slider 25 close to the sleeve 21, and a horizontally arranged spring 26 is installed between the other side of the slider 25 and the fixing seat 22. The controller 24 is installed on the slider 25. Specifically, before installing the grounding rod 7, the slider 25 can be slid to compress the spring 26. Then, after the grounding rod 7 is inserted into the sleeve 21, the slider 25 can be released. At this time, under the action of the spring 26 rebounding, the slider 25 can be driven to move in the opposite direction, so that the roller 23 abuts against the grounding rod 7; in addition, the roller 23 can also abut against the grounding rods 7 of different diameters.

[0024] The specific configuration of the sliding block 25 and the fixing base 22 is as follows: Figure 4 As shown, horizontally distributed guide grooves 27 are provided on two oppositely arranged inner walls of the fixed seat 22, and guide blocks 28 are slidably connected in the guide grooves 27. The guide blocks 28 are connected to the sliders 25. Specifically, when in use, when the slider 25 slides along the fixed seat 22, the guide blocks 28 and the guide grooves 27 can play a guiding role to improve the stability of the slider 25 during the sliding process.

[0025] In order to improve the stability of the clamp 13 when clamping the ground rod 7, Figure 3As shown, the chuck 13 includes a V-shaped rod 131 which is horizontally arranged and connected to the tooth plate 12. Both ends of the V-shaped rod 131 are hinged with a clamping block 133 through a hinge shaft 132 with a torsion spring. A limiting structure 134 is provided between the inner side of the clamping block 133 and the V-shaped rod 131, which enables the clamping block 133 to be arranged parallel to the tooth plate 12. Specifically, as shown in FIG. Figure 3 As shown, the limiting structure 134 is an inclined surface arranged on the inner side of the clamping block 133 and the end of the V-shaped rod 131. In the initial state, the limiting structure 134 can make the clamping block 133 parallel to the tooth plate 12; and in the process of the clamping head 13 clamping the grounding rod 7, the end of the clamping block 133 away from the V-shaped rod 131 first abuts against the grounding rod 7, and then when the clamping head 13 continues to approach the grounding rod 7, the grounding rod 7 can make the clamping block 133 rotate outward relative to the V-shaped rod 131, and at the same time apply force to the torsion spring. At this time, when the clamping head 13 clamps the grounding rod 7, the clamping block 133 is rotated outward relative to the V-shaped rod 131. After the head 13 moves into position, under the action of the torsion spring, the two clamping blocks 133 can be jointly abutted against the grounding rod 7, so that when clamping and positioning the grounding rods 7 of different diameters, the stability of the clamping head 13 in clamping the grounding rod 7 can be improved; in addition, a hinge shaft with a torsion spring can also be arranged in the middle of the hook-shaped position of the clamping rod 16, and a limiting structure can be arranged so that the hook-shaped position of the clamping rod 16 can be opened and closed. At this time, the stability of the hook-shaped position of the clamping rod 16 in clamping the grounding rod 7 can be improved.

[0026] Further, such as Figure 3 As shown, the end of the clamping block 133 away from the V-shaped rod 131 is installed with a ball 8. Specifically, when in use, when the end of the clamping block 133 away from the V-shaped rod 131 first abuts against the grounding rod 7, the ball 8 can abut against the grounding rod 7. At this time, under the action of the ball 8, the flexibility of clamping can be increased. At the same time, during the clamping process, the friction between the clamping block 133 and the grounding rod 7 can be reduced to reduce the damage to the grounding rod 7 caused by the clamping block 133; in addition, the ball 8 can also be installed at the end of the clamping rod 16 away from the rack 15. In this way, when the hook-shaped position of the clamping rod 16 is in the process of clamping the grounding rod 7, that is, when the ball 8 on the clamping rod 16 first abuts against the grounding rod 7, the friction between the hook-shaped position of the clamping rod 16 and the grounding rod 7 can also be reduced to reduce the damage to the grounding rod 7 caused by the clamping rod 16.

[0027] The specific configuration of the sliding connection between the rack 15 and the clamping plate 3 is as follows: Figure 1 and Figure 2As shown, both sides of the top surface of the base 4 are installed with limit seats 17 arranged parallel to the rack 15, and a limit groove is provided on the top surface of the limit seat 17, which horizontally penetrates the limit seat 17 and is arranged parallel to the limit seat 17. The vertical section of the limit groove is a trapezoidal structure with a narrow top and a wide bottom. The end of the rack 15 away from the clamping rod 16 is fixedly connected to a limit block 18, the bottom of the limit block 18 is adapted to the limit groove and is slidably connected to the limit seat 17 through the limit groove, and the top of the limit block 18 is located outside the limit groove, which can limit the amplitude of the up and down jumping of the rack 15; and the limit block 18 passes through the limit seat 17 through the limit groove and then penetrates The clamping plate 3, specifically, when in use, when the rack 15 is moving, the limit blocks 18 can slide along the limit seats 17 respectively to ensure the stability of the two racks 15 during the movement; in addition, a tray 9 that is arranged parallel to the base 4 and located in the clamping plate 3 can be installed on the top surface of the base 4 by bolts, and the two sides of the tray 9 are beveled edges arranged parallel to the limit seats 17. When in use, the limit seats 17 can be fixedly connected to the tray 9 respectively, and at the same time, the gear 11 can also be rotatably connected to the tray 9, which makes it convenient to install the limit seat 17 and the two gears 11 on the base 4.

[0028] The specific configuration of the toothed plate 12 and the threaded rod 14 in rotation is as follows: Figure 2 As shown, the end of the tooth plate 12 away from the chuck 13 is fixedly connected to the connecting plate 19, and the connecting block 10 is detachably connected to the connecting plate 19 through a bolt connection pair. A bearing is installed in the end of the connecting block 10 away from the connecting plate 19, and the end of the threaded rod 14 close to the tooth plate 12 is rotatably connected to the connecting block 10 through a bearing. Specifically, after removing the bolt connection pair, the connecting block 10 and the connecting plate 19 can be separated, which facilitates the disassembly and assembly between the tooth plate 12 and the threaded rod 14; a turning handle 141 is installed at the other end of the threaded rod 14, and the turning handle 141 can facilitate the rotation of the threaded rod 14.

[0029] Further, such as Figure 1 As shown, a level 6 is installed on the top surface of the clamping plate 3 . Specifically, when in use, the level 6 can be used to check whether the base 4 is in a horizontal state, so as to adjust the position of the base 4 .

[0030] The specific setting method of fixing the position of the base 4 is as follows: Figure 1As shown, the outer periphery of the base 4 is equipped with a plurality of groups of positioning devices 5 distributed along the circumference of the base 4, and the positioning devices 5 all include positioning blocks 51 fixedly connected to the base 4, and the bottom surface of the positioning blocks 51 can be set to be flush with the bottom surface of the base 4; the positioning blocks 51 are slidably connected with positioning rods 52 that vertically penetrate the positioning blocks 51, and the bottom ends of the positioning rods 52 are all pointed, and the top ends of the positioning rods 52 are coaxially equipped with positioning plates 53, and the positioning plates 53 are hinged with pull rings 54. Specifically, when in use, the base 4 is placed horizontally at a predetermined position, and the ground at the predetermined position is ensured to be level. The base 4 is leveled to stably support the base 4, and then the tip of the positioning rod 52 is hammered into the ground until the positioning plate 53 abuts against the positioning block 51, and the position of the base 4 can be fixed to ensure the stability of the bracket of the present invention during use; in addition, in the process of fixing the base 4, the position of the base 4 can be fine-tuned, or after the position of the base 4 is fixed, the depth of the positioning rod 52 inserted into the ground can be adjusted to make the base 4 reach a horizontal state; secondly, by setting the pull ring 54, the positioning rod 52 can be easily pulled out from the ground to facilitate the removal of the bracket.

[0031] The use of the present invention is as follows: Figures 1 to 4 As shown, first, the base 4 is placed horizontally at a predetermined position, and the ground at the predetermined position is ensured to be flat, and then the base 4 is fixed by the positioning device 5. At this time, the level meter 6 can be used to check whether the base 4 is horizontal. If necessary, the base 4 can be made horizontal by fine-tuning the position of the base 4 or adjusting the depth of the positioning rod 52 inserted into the ground; secondly, after the grounding rod 7 passes through the sleeve 21, the clamping plate 3, the clamping device 1 and the base 4 in sequence, the slider 25 is loosened to make the roller 23 contact with the grounding rod 7; furthermore, by rotating the threaded rod 14, the toothed plate 12 can be driven to move horizontally. The toothed plate 12 moves in the direction, and during the movement, the hook position of the clamping rod 16 and the clamping head 13 can be driven to approach the grounding rod 7 at the same time, so as to clamp and position the grounding rods 7 of different diameters. At this time, under the action of the clamping device 1, the grounding rod 7 can be perpendicular to the base 4, and because the base 4 is parallel to the ground, the grounding rod 7 can be kept in a vertical state and perpendicular to the ground; finally, when the grounding rod 7 is inserted into the ground, the roller 23 will roll as the grounding rod 7 moves downward, and then the encoder and the controller 24 can measure and display the depth information in real time.

[0032] In general, the structure of the present invention is compact and reasonable, and the various components are closely matched, which can ensure the stability of the present invention during use, so as to facilitate the clamping and positioning of the grounding rod 7, so that during the installation of the grounding rod 7, the grounding rod 7 can always be kept in a vertical state.
