Description

Technical Field

[0001] This utility model relates to the field of power maintenance safety equipment technology, specifically to a turning-type power grounding wire. Background Technology

[0002] Power grounding wires are a common safety device used during power maintenance. They are used to suspend grounding wires over potentially energized parts of equipment to prevent injury to personnel and equipment from accidental energization during maintenance. To prevent electric shock accidents caused by personnel manually installing grounding wires on equipment that may become accidentally energized, modern power grounding wires are equipped with an insulated operating rod in addition to the grounding cable itself. Operators use the operating rod to guide the hook with the grounding cable to the target location, and then use the control device on the operating rod to close or open the hook, ultimately completing the connection or removal of the grounding wire.

[0003] Currently, most power grounding wire operating rods are straight rods. However, in some indoor spaces with numerous pieces of equipment, the close arrangement of equipment creates limited operating space, and obstacles may exist between the operator and the point where the grounding wire is attached. In such cases, using a straight rod grounding wire operating rod makes it difficult to quickly and effectively extend the hook into the target area, potentially leading to inadequate grounding safety procedures.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Therefore, they should not be construed as limitations on this utility model.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] Example 1

[0034] like Figures 1 to 3As shown, this embodiment provides a bend-type power grounding wire, including a hook assembly, a crossbar 8, and a vertical bar 9. As in the prior art, the grounding cable 5 is connected to the hook assembly, which is made of metal. The grounding cable 5 achieves hooking and conductivity with the target device through the hook assembly. In this embodiment, the hook assembly is located at the end of the crossbar 8, and one end of the vertical bar 9 is connected to the crossbar 8 at an angle. A rotating handle 11 is provided at the other end of the vertical bar 9. Like existing grounding wire operating rods, the components between the hook and the operator, such as the crossbar 8 and the vertical bar 9, should be insulated and made of materials such as plastic or nylon. The rotating handle 11 should also preferably be insulated.

[0035] A transmission rod 18 is provided inside the longitudinal rod 9. One end of the transmission rod 18 is connected to the rotating handle 11, and a gear 16 is provided at the other end of the transmission rod 18. Since the transmission rod 18 is also located between the hook and the operator, it may become a conduction path for current, so it should preferably be insulated.

[0036] A rack 17 is provided inside the crossbar 8. The rack 17 meshes with the gear 16 and slides along the axial direction of the crossbar 8 through a sliding groove inside the crossbar 8.

[0037] The hook assembly includes a hook body 3 and a hook slider 4. The hook body 3 is connected to the crossbar 8. The hook slider 4 is connected to the rack 17. Driven by the rack 17, the hook slider 4 can open and close with the hook body 3.

[0038] When using the above-mentioned device, first, by holding the vertical rod 9, the entire device is extended towards the target area. When encountering an obstacle, the device is bypassed by the turning structure formed between the vertical rod 9 and the horizontal rod 8 until the hook assembly hooks onto the point where it needs to touch the ground. Then, the other hand holds the rotating handle 11 and rotates it. This rotation drives the gear 16 to rotate via the transmission rod 18. The rotating gear 16 then converts the power into linear motion through the rack 17. The linear motion of the rack 17 is transmitted to the hook slider 4, causing the hook slider 4 to slide closer to the hook body 3, ultimately achieving the closure of the hook assembly (i.e., Figure 3 (As shown in the diagram). When it is necessary to remove the device, the hook body 3 and the hook slider 4 are opened by rotating the rotating handle 11 in the opposite direction (i.e., ...). Figure 2 Once the device is in the indicated state, it can be easily removed.

[0039] This device, through the arrangement of vertical rod 9 and horizontal rod 8, and the transmission mechanism of rack 17 and gear 16, not only achieves the turning shape of the entire rod, thus bypassing obstacles between the operator and the target location, but also ensures that the hook assembly still receives power to perform the clamping action, thereby reliably connecting the grounding wire. Moreover, the entire device has a simple structure, low cost, and is conducive to widespread adoption.

[0040] Based on the above embodiments, in a preferred embodiment, such as Figures 1 to 3 As shown, the hook head body 3 includes a hook head bending portion 1 and a hook head connecting portion 2. The hook head bending portion 1 is the main part of the hook head body 3 that performs the hooking function. One end of the hook head connecting portion 2 is connected to the hook head bending portion 1, and a connecting ring 6 is provided at the other end of the hook head connecting portion 2. The hook head bending portion 1, the hook head connecting portion 2, and the connecting ring 6 together form a C-shaped structure. The connecting ring 6 is sleeved on the crossbar 8. The connecting ring 6 and the crossbar 8 form a snap-fit ​​relationship in the axial direction. For example, a first annular groove 19 can be opened on the crossbar 8, and a first set screw 12 extending into the first annular groove 19 can be provided on the connecting ring 6 to achieve the snap-fit ​​relationship in the axial direction and prevent axial movement. At the same time, because the connecting ring 6 can rotate while sleeved on the crossbar 8, a rotational connection relationship is formed between the two in the circumferential direction. The hook head connecting portion 2 has a gap between the connecting ring 6 and the rotation axis of the connecting ring 6 in the radial direction, that is, the hook head connecting portion 2 is in an eccentric position.

[0041] This design is because when the vertical bar 9 extends, it is often in an upward angle. In most cases, this will create an angle between the hook assembly and the part to be hooked and clamped. If the hook assembly is fixed and cannot rotate, its opening will clamp in an inclined position, and the concave part of the hook will not be able to fully contact the part to be hooked. In other words, the part to be hooked is in a state where it is easy to detach, which is very detrimental to the clamping stability. However, by setting the hook body 3 to be able to rotate freely, and the hook connection part 2 is in an off-center position, the hook connection part 2 will naturally droop to the lowest point, and the entire hook assembly will be in a vertical position. When the vertically positioned hook assembly encounters the area to be hooked, the operator simply needs to continue pushing the hook assembly. The hook connection 2, which is in an off-center position, will be blocked from moving by the area to be hooked, while the entire hook assembly can continue to move further in. This causes the hook connection 2 to deflect, gradually changing the entire hook assembly from a vertical to a horizontal position, ultimately achieving a clamping posture that matches the angle of the area to be hooked. At this point, the locking operation can fully utilize the locking effect of the hook's recessed area, preventing disengagement.

[0042] Furthermore, it should be noted that this embodiment only demonstrates a structural arrangement in which the connecting ring 6 and the crossbar 8 form a snap-fit ​​relationship in the axial direction and a rotational connection relationship in the circumferential direction. Other technical means that can achieve this function, such as not using a ring groove structure, but setting limiting devices at both ends after the connecting ring 6 is sleeved, can also be applied here.

[0043] Based on the above embodiments, in a preferred embodiment, such as Figures 1 to 3 As shown, the end of the hook slider 4 is concave and can form a closed structure with the hook bend 1 when closed. The hook connecting part 2 is straight, and the hook slider 4 and the hook connecting part 2 form a snap-fit ​​sliding relationship. The hook slider 4 and the rack 17 have a rotatable connection, and the hook slider 4 and the connecting ring 6 have the same axis of rotation.

[0044] After the above settings, the hook slider 4 can rotate together with the hook connecting part 2. In the previous embodiment, it was not considered whether the hook slider 4 also had the corresponding rotation capability, because if the working surface of the hook slider 4 is a plane, its rotation is irrelevant. However, if the working surface of the hook slider 4 is a concave surface that cooperates with the hook bending part 1, then in order to achieve a better clamping effect, the hook slider 4 also needs to be set to be rotatable. Similar to the structure of the connecting ring 6 with the ring groove and the set screw mentioned above, this embodiment also uses the second set screw 14 and the second ring groove 15 to achieve the corresponding function, but obviously it is not limited to using only this structure. Regarding the specific structure of the second set screw 14 and the second ring groove 15, in this embodiment, a slide rod 13 is provided between the hook slider 4 and the rack 17, a second ring groove 15 is provided at the connection end of the slide rod 13 and the rack 17, and a second set screw 14 extending into the second ring groove 15 is provided on the rack 17. Of course, the second set screw 14 and the second annular groove 15 can also be set between the slide bar 13 and the hook slider 4, which are all replacements between conventional means.

[0045] Based on the above embodiments, in a preferred embodiment, such as Figures 1 to 3 As shown, the crossbar 8 is a straight bar, forming a 90° angle with the vertical bar 9. The rack 17 and the hook slider 4 are connected by a straight sliding rod 13. This implementation method has a relatively simple structure and very low cost, but it can handle most situations in application scenarios with obstacles. It is a widely applicable, low-cost, and mass-producible solution.

[0046] Based on the above embodiments, in a preferred embodiment, such as Figure 1As shown, a camera 7 is installed on the crossbar 8, facing the hook assembly. A display screen 10 is installed on the vertical bar 9, and the camera 7 and the display screen 10 are connected via optical fiber. In some cases, the presence of obstacles makes it difficult for the operator to directly observe the area to be hooked. In such cases, in order to perform grounding wire connection work more reliably, it is necessary to set up a camera and display device for indirect observation. The reason for using an optical fiber transmission scheme is to avoid conductivity between related devices and prevent increasing the risk of electric shock to the operator.

[0047] Example 2

[0048] like Figures 4 to 6 As shown, this embodiment provides a bend-type power grounding wire. The grounding wire pole is largely the same as that of Embodiment 1, except that the horizontal bar 8 includes a swing rod 20 and a fixed rod 21. The fixed rod 21 is connected to the vertical bar 9 at an angle. A rack 17 is disposed within the fixed rod 21. The swing rod 20 and the fixed rod 21 are rotatably connected, and a locking device is provided at the rotatable connection between them. The locking device is used to lock the included angle between them; a simple example is the use of a screw 22 and a locking nut 23, while other mechanisms such as spring clips can also be used. The hook assembly is disposed at the free end of the swing rod 20. The swing amplitude of the swing rod 20 is within the plane defined by the fixed rod 21 and the vertical bar 9. The hook slider 4 and the rack 17 are connected by a linear transmission device. The linear transmission device mentioned here refers to a device capable of linear power transmission, such as a cable mechanism similar to a brake cable, or a hydraulic transmission mechanism as described below.

[0049] Generally, a fixed angle between the horizontal bar 8 and the vertical bar 9, especially 90°, is sufficient for most situations. However, maintenance personnel may encounter situations requiring various large turning angles in multiple applications, and configuring a grounding rod for each turning scenario would be very inconvenient. Therefore, this embodiment, based on embodiment 1, further expands the functionality to include an adjustable turning angle, thereby improving the equipment's adaptability.

[0050] Based on the above embodiments, in a preferred embodiment, such as Figures 4 to 6As shown, the linear transmission device includes a first hydraulic rod 24, a hose 25, and a second hydraulic rod 26. The hydraulic rod is a small piston-rod type hydraulic cylinder, but because the force to be transmitted is relatively small, high-strength metal components are unnecessary; materials and structures similar to those of medical syringes can be used. The hydraulic rod necessarily includes a cylinder and a rod. The cylinder of the first hydraulic rod 24 is fixedly connected to the swing rod 20, and the rod of the first hydraulic rod 24 is connected to the hook slider 4. The cylinder of the second hydraulic rod 26 is fixedly connected to the fixed rod 21, and the rod of the second hydraulic rod 26 is connected to the rack 17. The cylinders of the first hydraulic rod 24 and the second hydraulic rod 26 are connected by the hose 25, thus enabling the transmission of linear power between the two hydraulic rods when one hydraulic rod retracts and the other extends. The reason a linear hydraulic transmission mechanism is preferred over a cable-operated mechanism is that the cable-operated mechanism can only transmit the pulling force of rack 17 in one direction, specifically the pull-back direction. For the force in the other direction, i.e., the forward thrust, the cable-operated mechanism needs to provide power through a return spring, and cannot transmit it through the reverse movement of rack 17. Regarding the specific structure of the hook assembly, if a cable-operated mechanism were used, and the transmission system structure were not overly complex, the clamping force of the hook would rely solely on the return spring to provide the forward thrust. The clamping force of the hook is crucial in the entire device, preventing the grounding wire from loosening after connection, thus requiring operator control by feel. Therefore, a hydraulic transmission mechanism that can transmit power in both directions, especially effectively transmitting the forward thrust, is a more suitable choice.

[0051] Based on the above embodiments, in a preferred embodiment, such as Figure 5 and 6 As shown, a tee connector 27 is provided on the hose 25. The two opposite ends of the tee connector 27 are connected to the hose 25, and a removable plug is provided at the middle port of the tee connector 27. The tee connector 27 and the removable plug are provided to facilitate the injection of hydraulic oil or other fluids into the system by removing the plug during equipment manufacturing and subsequent maintenance. This is simpler than installing an oil injection device on the hydraulic rod.

[0052] Based on the above embodiments, in a preferred embodiment, such as Figure 5 and 6As shown, the swing rod 20 and the fixed rod 21 are detachably connected, and the tee connector 27 is located at the rotating connection between the swing rod 20 and the fixed rod 21. The hydraulic rods may experience minor oil leakage. Over long-term use, this inevitably leads to inconsistencies in the stroke between the two hydraulic rods, necessitating the replenishment of oil to compensate for the leakage. Since the swing rod 20 and the fixed rod 21 are inherently movable, the rotation and locking functions can be easily achieved using only the screw 22 and the locking nut 23, making disassembly relatively easy. Therefore, placing the tee connector 27 here allows for easy oil replenishment by simply disassembling the swing rod 20 and the fixed rod 21, saving time.

[0053] Based on the above embodiments, in a preferred embodiment, when viewed from the axial surface of gear 16, that is, from... Figure 5 and 6 Viewed from the indicated direction, rack 17 and second hydraulic rod 26 are arranged side by side, respectively on both sides of gear 16. The ends of the rod body of second hydraulic rod 26 and rack 17 are aligned and fixedly connected by connecting plate 28. Compared to a linear series connection of second hydraulic rod 26 and rack 17, this embodiment places them side by side and on both sides of gear 16. This allows the length of fixing rod 21 to be greatly reduced without excessively increasing its width, making the entire device more compact.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
