Description

Technical Field

[0001] This invention relates to the field of power facility laying device technology, and more specifically to an auxiliary grounding pile device for power equipment grounding testing. Background Technology

[0002] In the production activities of the power sector, grounding tests and measurements are frequently required, including testing the grounding resistance and reactance of substations and transmission and distribution lines, as well as installing grounding wires before power outage maintenance.

[0003] Due to the complex on-site environment, often facing geological conditions such as hard soil, gravel, and rocks, manual grounding pile driving is extremely difficult. After the grounding pile is driven into the hard soil, it is also difficult to insert and remove it, resulting in low work efficiency. At the same time, when workers use traditional hammering and manual pulling methods, they are prone to injury due to excessive force. This invention proposes a new solution to the above problems. Summary of the Invention

[0004] In order to overcome at least one of the above-mentioned disadvantages, the present invention provides an auxiliary grounding pile device for power equipment grounding testing.

[0005] The objective of this invention can be achieved by adopting the following technical solution: This application provides an auxiliary grounding pile driving device for power equipment grounding testing, comprising: The base has a through hole. The bracket is mounted on the base; A ground-driving pile module is mounted on a support. The ground-driving pile module includes a rack, a hook, a gear, and a rocker arm. The gear is mounted on the support. The rack is vertically mounted and meshes with the gear. One end of the rack is connected to a hook for connecting to a grounding rod. A through hole is located directly below the rack. The rocker arm is poweredly connected to the gear and is used to drive the gear to rotate forward or backward, thereby driving the grounding rod to rise and fall through the rack.

[0006] In one possible implementation, the support includes: The upright is longitudinally arranged on the base, and the upright and the base are detachably connected; A horizontal bar is horizontally mounted on the vertical pole, and the pile driving module is connected to the horizontal bar.

[0007] In one possible implementation, the crossbar includes: A fixed section, which is detachably connected to the upright; The diagonal brace section has one end rotatably connected to the fixed section, and the other end is used to embed into the base to form a support.

[0008] In one possible implementation, the base includes: A foot pedal, located on one side of the upright; An anti-tilting rod is provided, which is located on the same horizontal plane as the foot pedal rod and on the other side of the foot pedal rod.

[0009] In one possible implementation, the base further includes: Side support members are provided on both sides of the pedal rod and are located on the same horizontal plane as the pedal rod. The side support members include side support rods and storage slots. The storage slots are provided on the side walls of the pedal rods. The side support rods can be stored in the storage slots or unfolded to form triangular supports.

[0010] In one possible implementation, the upright, the crossbar, and the base are all detachably connected.

[0011] In one possible implementation, the pile driving module further includes: A spacer sleeve is disposed on the bracket, and the gear is disposed inside the spacer sleeve; A first braking module is disposed within the spacer. The second braking module is disposed within the spacer. The stop block, when switching between a first position and a second position, causes the corresponding first braking module or second braking module to stop the gear, thereby realizing the unidirectional transmission of the gear.

[0012] In one possible implementation, the first braking module includes a first pawl and a first elastic element. The connecting end of the first pawl is rotatably connected to the spacer, and the free end of the first pawl is used to mesh with the gear. One end of the first elastic element is connected to the spacer, and the other end is connected to the first pawl, for applying an elastic force to the first pawl to move toward the gear. The second braking module includes a second pawl and a second elastic element. The connecting end of the second pawl is rotatably connected to the spacer, and the free end of the second pawl is used to mesh with the gear. One end of the second elastic element is connected to the spacer, and the other end is connected to the second pawl, for applying an elastic force to the second pawl to move closer to the gear.

[0013] In one possible implementation, the stop block is connected to a knob, and the stop block is switched between the first position and the second position by rotating the knob. The side wall of the stop block includes a first abutting plane and a second abutting plane, and a transition arc surface is formed between the first abutting plane and the second abutting plane. When the stop block is in the first position, the first abutting plane abuts against the first pawl, and the transition arc surface abuts against the second pawl, causing the second pawl to separate from the gear, thereby forming a stop for the gear that is reversing. When the stop block is in the second position, the second abutting plane abuts against the second pawl, and the transition arc surface abuts against the first pawl, causing the first pawl to separate from the gear, thereby forming a stop for the forward-rotating gear.

[0014] In one possible implementation, when the first pawl engages with the gear, it can only drive the gear to rotate forward, thereby driving the grounding rod to descend through the rack and the hook. When the second pawl engages with the gear, it can only drive the gear to reverse and drive the grounding rod to rise through the rack and the hook.

[0015] The beneficial technical effects of this invention are as follows: According to this disclosure, the auxiliary grounding pile driving device for power equipment grounding testing ensures that the grounding stake is vertically inserted into the precise entry point by setting through holes on the base and keeping it coaxial with the rack. This avoids problems such as repeated hammering and tilting due to instability caused by manual straightening. The bracket provides a stable support structure, improving the stability of the device during operation. In the grounding pile driving module, the meshing transmission of the rack and gear converts the rotational motion of the rocker arm into the linear motion of the rack, allowing the operator to continuously drive the gear in small-angle, high-frequency swinging. The grounding stake, connected by a hook, completes precise insertion and extraction under the forward and reverse drive of the gear. The operator only needs to control the lifting and lowering process of the grounding stake with the rocker arm, avoiding the safety risks of traditional manual hammering and manual pile extraction. At the same time, the mechanical transmission improves the stability, control accuracy, and efficiency of the operation. Attached Figure Description

[0018] In the following detailed disclosure, these embodiments are fully described with reference to the accompanying drawings. In order to enable those skilled in the art to understand and clarify the technical solution of the present invention more clearly, the embodiments described below are not limited thereto. The present invention will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0019] This application provides an auxiliary grounding pile driving device for power equipment grounding testing, such as... Figures 1-4 As shown, the device includes a base 1, a support 2, and a grounding pile module 3. The base 1 has a through hole 14. The support 2 is mounted on the base 1, and the grounding pile module 3 is mounted on the support 2. The grounding pile module 3 includes a rack 31, a hook 32, a gear 33, and a rocker arm 35. The gear 33 is mounted on the support 2. The rack 31 is vertically mounted and meshes with the gear 33. One end of the rack 31 is connected to the hook 32 for connecting to the grounding rod. The through hole 14 is located directly below the rack 31. The rocker arm 35 is powered by the gear 33 and is used to drive the gear 33 to rotate forward or backward, thereby driving the grounding rod to rise and fall through the rack 31.

[0020] The grounding test auxiliary grounding pile device provided in this embodiment ensures that the grounding stake is inserted vertically and accurately into the correct location by setting a through hole 14 on the base 1 and keeping it coaxial with the rack 31. This avoids problems such as repeated hammering and tilting due to instability caused by manual straightening. The bracket 2 provides a stable support structure, improving the stability of the device during operation. In the grounding pile module 3, the meshing transmission between the rack 31 and the gear 33 converts the rotational motion of the rocker arm 35 into the linear motion of the rack 31, allowing the operator to continuously drive the gear 33 with small-angle, high-frequency swinging. The grounding stake connected by the hook 32 completes the precise insertion and extraction action under the forward and reverse drive of the gear 33. The operator only needs to control the lifting and lowering process of the grounding stake through the rocker arm 35, avoiding the safety risks of traditional manual hammering and manual pile extraction. At the same time, the mechanical transmission improves the stability, control accuracy and efficiency of the operation.

[0021] In one possible implementation, such as Figure 2As shown, the support 2 includes an upright 21 and a crossbar 22. The upright 21 is longitudinally arranged on the base 1 and is detachably connected to the base 1. The crossbar 22 is transversely arranged on the upright 21, and the ground pile module 3 is connected to the crossbar 22.

[0022] The vertical detachable connection between the upright 21 and the base 1, and the horizontal assembly between the crossbar 22 and the upright 21, create a stable working platform, enabling precise spatial positioning and extension of the pile driving module 3. The upright 21 and the base 1 are detachable by bolts, facilitating disassembly and assembly, reducing space occupation, and improving the adaptability and portability of the device under different terrains and operational requirements.

[0023] In one possible implementation, such as Figure 2 As shown, the crossbar 22 includes a fixed section 221 and a diagonal brace section 222. One end of the diagonal brace section 222 is rotatably connected to the fixed section 221, and the other end is used to embed into the base 1 to form a support.

[0024] The fixed section 221 serves as the main body and is used to support the pile module 3, providing the main support force. The inclined support section 222 can be connected to the fixed section 221 via a hinge. The end of the inclined support section 222 is designed as a plug-in structure that is embedded in the base 1. The protrusion is located at the bottom of the inclined support section 222 and is usually cylindrical or wedge-shaped. It is used to engage with the groove on the base 1 to ensure that there is no shaking after insertion, and can be quickly positioned and locked to prevent the fixed section 221 from bending and deforming during support.

[0025] Furthermore, the fixed section 221 can also be rotatably connected to the upright 21 via a hinge, allowing the crossbar to be folded into a state that fits against the upright when not in use, significantly reducing the overall volume and facilitating transportation and storage. The folding process can be completed by a single person, making it particularly suitable for scenarios where grounding tests of power equipment require frequent disassembly and assembly.

[0026] Furthermore, one end of the diagonal brace 222 is hinged to the fixed section 221, and the other end is connected to the upright 21. The diagonal brace 222 and the upright 21 provide support for the fixed section 221 and keep the fixed section 221 in a horizontal position, thereby allowing the rack 31 to move up and down along the longitudinal direction.

[0027] In one possible implementation, such as Figure 2 As shown, the base 1 includes a foot pedal 11 and an anti-tilting rod 12. The foot pedal 11 is located on one side of the upright 21, and the anti-tilting rod 12 is located on the same horizontal plane as the foot pedal 11 and on the other side of the foot pedal 11.

[0028] Among them, by setting up foot pedals 11 and anti-tilting rods 12 on both sides of the pole 21 on the same horizontal plane, a stable support structure based on the lever balance principle is constructed. When the operator applies force on one side of the crossbar 22, the foot pedal 11, as the main load-bearing point, directly transmits the downward pressure to the ground, effectively overcoming the tendency of the device to tilt forward. The anti-tilting rod 12 on the other side, as the balance fulcrum, accurately suppresses the risk of the rear end of the base 1 tilting up due to the reverse force on the rack 31.

[0029] In one possible implementation, such as Figure 2 As shown, the base 1 also includes a side support member 13. The side support member 13 is disposed on both sides of the foot pedal member 11 and is located on the same horizontal plane as the foot pedal member 11. The side support member 13 includes a side support rod and a storage groove. The storage groove is disposed on the side wall of the foot pedal member 11. The side support rod can be stored in the storage groove or unfolded to form a triangular support.

[0030] The side support member 13 integrates the side support rod with the storage slots on both sides of the foot pedal member 11. When the support rod is extended from the storage slot, the support rod and the foot pedal member 11 form a triangular support area on the horizontal plane, which enhances the anti-overturning ability on soft or uneven ground. In the non-operating state, the support rod can be completely retracted into the storage slot, ensuring the compactness of the device and not taking up extra space when stored.

[0031] In one possible implementation, the upright 21, the crossbar 22, and the base 1 are all detachably connected.

[0032] The upright 21 is connected to the base 1 and the crossbar 22 is connected to the upright 21 using standardized mechanical interfaces. The upright 21 is fixed to the base 1 with bolts, and the upright 21 and the crossbar 22 can be connected by hinges and fixed by inserting pins. This allows the operator to complete the construction of the three-dimensional support frame on site with simple actions, ensuring the compactness of the device when folded and stored, and enabling efficient installation on the work site, perfectly meeting the mobility requirements of power maintenance operations.

[0033] In one possible implementation, such as Figure 3 and Figure 4 As shown, the pile driving module 3 also includes a spacer, a first braking module 36, a second braking module 37, and a stop block 38. The spacer is mounted on the bracket 2, and the gear 33 is mounted inside the spacer. The first braking module 36 is mounted inside the spacer, and the second braking module 37 is mounted inside the spacer. When the stop block 38 switches between the first position and the second position, the corresponding first braking module 36 or second braking module 37 stops the gear 33, realizing the one-way transmission of the gear 33.

[0034] The spacer is fixed in an axial through slot on the crossbar 22. It houses the rack 31, gear 33, first braking module 36, second braking module 37, and stop block 38. The stop block 38 is designed to be rotatable and can switch between a first position and a second position. When the stop block 38 is in the first position, it triggers the first braking module 36 to mechanically stop the gear 33, thus restricting the gear 33 to rotate only in the forward direction. Conversely, when the stop block 38 is switched to the second position, the second braking module 37 is activated and stops the gear 33, realizing the reverse rotation function of the gear 33. The displacement of the stop block 38 directly controls the intervention of different braking modules, completing the switching process of the transmission direction of the gear 33.

[0035] In one possible implementation, such as Figure 3 and Figure 4 As shown, the first braking module 36 includes a first pawl 361 and a first elastic member 362. The connecting end of the first pawl 361 is rotatably connected to the spacer, and the free end of the first pawl 361 is used to mesh with the gear 33. One end of the first elastic member 362 is connected to the spacer, and the other end is connected to the first pawl 361, which is used to apply a spring force to the first pawl 361 to move closer to the gear 33. The second braking module 37 includes a second pawl 371 and a second elastic member 372. The connecting end of the second pawl 371 is rotatably connected to the spacer, and the free end of the second pawl 371 is used to mesh with the gear 33. One end of the second elastic member 372 is connected to the spacer, and the other end is connected to the second pawl 371, which is used to apply a spring force to the second pawl 371 to move closer to the gear 33.

[0036] Both braking modules employ a combination of pawls and elastic elements. In the first braking module 36, the first pawl 361 is hinged to the spacer via a connecting end, with its free end engaging with the gear teeth of the gear 33. Simultaneously, the first elastic element 362 is anchored at both ends to the spacer and the first pawl 361, continuously providing an elastic preload that presses its free end against the gear 33. Symmetrically, the second pawl 371 of the second braking module 37 is also rotatably connected to the spacer via a connecting end, with its free end having an equivalent gear engagement function. An independent second elastic element 372 applies a spring force toward the gear 33 using the same working principle. This symmetrical dual-module configuration allows the stop block 38 to select the corresponding braking module for unidirectional locking when switching.

[0037] In one possible implementation, such as Figure 3 and Figure 4As shown, the stop block 38 is connected to a knob 34. By rotating the knob 34, the stop block 38 can be switched between a first position and a second position. The side wall of the stop block 38 includes a first abutting plane 381 and a second abutting plane 382, ​​and a transition arc surface 383 is formed between the first abutting plane 381 and the second abutting plane 382. When the stop block 38 is in the first position, the first abutting plane 381 abuts against the first pawl 361, and the transition arc surface 383 abuts against the second pawl 371, causing the second pawl 371 to disengage from the gear 33, which is used to stop the gear 33 from rotating in reverse. When the stop block 38 is in the second position, the second abutting plane 382 abuts against the second pawl 371, and the transition arc surface 383 abuts against the first pawl 361, causing the first pawl 361 to disengage from the gear 33, which is used to stop the gear 33 from rotating in the forward direction.

[0038] The rotation of knob 34 directly drives the stop block 38 to rotate around the axis, switching it between the first position and the second position. The precise switching of the working state of the braking module is achieved through the rotation input of knob 34.

[0039] The sidewall of the stop block 38, through the structure of the first abutment plane 381, the second abutment plane 382, ​​and the transition arc surface 383, controls the two pawls during position switching. When the stop block 38 is in the first position, the first abutment plane 381 and the first pawl 361 maintain rigid contact to keep them engaged with the gear 33, while the transition arc surface 383 contacts the second pawl 371 and forces it to overcome the elastic force and disengage from the gear 33. Conversely, in the second position, the second abutment plane 382 abuts the second pawl 371 to engage the gear 33, while the transition arc surface 383 pushes the first pawl 361 to disengage. The working state of the two braking modules is adjusted by the physical contour of the stop block 38.

[0040] In one possible implementation, such as Figure 3 and Figure 4 As shown, when the first pawl 361 meshes with the gear 33, the gear 33 can only drive the gear 33 to rotate forward, thereby driving the grounding rod to descend through the rack 31 and the hook 32; when the second pawl 371 meshes with the gear 33, the gear 33 can only drive the gear 33 to rotate in reverse, thereby driving the grounding rod to rise through the rack 31 and the hook 32.

[0041] Among them, such as Figure 3 As shown, when the first pawl 361 is engaged with the gear 33, the gear 33 can only rotate in one direction (forward). This rotational motion drives the engaged gear 33 to rotate synchronously forward, and then, through the linear motion of the rack 31 and the linkage of the hook 32, the lowering action of the grounding rod is finally achieved; conversely, as... Figure 4As shown, when the second pawl 371 engages with the gear 33, the gear 33 can only rotate in the opposite direction (reverse rotation). This reverse rotation drives the gear 33 to rotate in reverse, which is converted into the upward movement of the grounding rod through the transmission of the rack 31 and the hook 32. Through the directional engagement of the pawl, the correspondence between the rotation direction of the gear 33 and the lifting and lowering action of the grounding rod is precisely locked.
