Description

Technical Field

[0001] This application relates to the technical field of electric power engineering, and in particular to a locking type grounding device for conductors. Background Art

[0002] The grounding wire is a safety tool for temporarily short - circuiting and grounding the de - energized equipment. It is an important component specifically used for temporarily short - circuiting and grounding the de - energized transmission conductors. Its function is to prevent the equipment from suddenly powering on and the induction voltage generated by adjacent high - voltage energized equipment from harming the human body when performing maintenance or other operations on high - voltage equipment. At the same time, it discharges the remaining charges of the de - energized equipment. Only when its performance is reliable can the safety of the power outage maintenance of high - voltage transmission lines be ensured.

[0003] The current grounding wire setting method mostly adopts the two - person erection method. This method requires two people to cooperate. One person holds the wire clip of one phase of the grounding wire, and the other person holds the grounding wire gun and aims at the lower - end metal head of the hook - type clip. If the guardian is not allowed to participate in the work according to the requirements of the "Safety Regulations", then three people are required to operate each time the grounding wire is erected, which is cumbersome and inefficient. Therefore, a locking type grounding device for conductors is proposed to solve the above - mentioned technical problems. Utility Model Content

[0004] One of the purposes of this application is to provide a locking type grounding device for conductors.

[0005] To achieve the above - mentioned purpose, the technical solution adopted in this application is as follows: A locking type grounding device for conductors includes a hook body, a locking hook assembly, a limiting assembly, and a traction rope. A lifting hook is provided at the top of the hook body. The locking hook assembly is movably arranged on the hook body. The limiting assembly is arranged on the hook body and cooperates with the locking hook assembly. The traction rope is connected and cooperated with the lifting hook. When hanging, the hook body is adapted to be hung on the conductor through the traction rope. At this time, the locking hook assembly is adapted to perform a locking action under the drive of the conductor, and the limiting assembly is adapted to lock the locking hook assembly, so that the wiring clip is locked to the conductor.

[0006] Preferably, a clamping assembly is further arranged inside the hook body. After hanging, the clamping assembly is adapted to abut against the conductor so that the hook body is limited to the conductor.

[0007] Preferably, the clamping assembly includes a pair of clip pieces. The clip pieces are elastically and rotatably installed on both sides of the hook body. The clip pieces are adapted to abut against the outside of the conductor under the action of elastic force.

[0008] Preferably, the end of the towing rope has a first connection point and a second connection point. The first connection point is connected to the limiting component, and the second connection point is in hanging connection with the lifting hook. The towing rope is adapted to drive the hook body through the second connection point during the hanging process. When disengaging, the towing rope is driven downward to disengage the second connection point from the lifting hook, and then the towing rope is lifted to rotate the hook body and trigger the action of the limiting component, so that the limiting component releases the locking of the locking hook component. At this time, the locking hook component is adapted to perform an unlocking action under the drive of the wire, and then the wiring clip is disengaged from the wire.

[0009] Preferably, the locking hook component includes a locking frame and a locking rod. The locking frame is rotatably installed on the hook body through the locking rod, and the locking rod cooperates with the limiting component. Before hanging, the limiting component is adapted to cooperate with the locking rod at a first position so that the locking frame is in an unlocked state. When hanging, the locking frame is adapted to rotate under the drive of the wire, and then the opening of the locking frame and the opening of the hook body cooperate to form a locking cavity for cooperating with the wire. At this time, the limiting component is adapted to cooperate with the locking rod at a second position so that the locking frame is in a locked state.

[0010] Preferably, the limiting component includes a limiting rod and an elastic member. The limiting rod is vertically slidably installed at the bottom end of the hook body through the elastic member. The first end of the limiting rod is connected to the first connection point, and the second end of the limiting rod cooperates with the locking rod. When hanging, the limiting rod is adapted to be in contact with the locking rod under the action of elastic force. When disengaging, the limiting rod is adapted to move away from the locking rod under the drive of the towing rope.

[0011] Preferably, a wiring member connected to the grounding wire is rotatably installed on the locking frame. When hanging, the grounding wire is adapted to be rotationally adjusted along the wiring clip through the wiring member. When disengaging, the wiring clip is adapted to rotate along the end of the wiring member, so that the grounding wire maintains a stable state.

[0012] Preferably, before hanging, the angle between the grounding wire and the towing rope is α, where 0 ≤ α ≤ 60°.

[0013] Preferably, the rotation point of the wiring member and the locking frame is located at the end away from the opening of the locking frame. When hanging, the locking frame is also adapted to rotate under the drive of the grounding wire.

[0014] Preferably, a suspension ring is installed at the second connection point, and the suspension ring is in hanging connection with the lifting hook.

[0015] Compared with the prior art, the beneficial effects of the present application are as follows:

[0016] The utility model adopts a method of grounding the wire by setting a traction rope in cooperation with a grounding clamp. That is, at this time, only one staff member is required to operate to complete the hanging of the entire grounding wire, greatly simplifying the operation process, improving work efficiency, reducing operation risks, and enhancing operation safety.

[0030] Next, in combination with the detailed implementation manners, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0031] In the description of the present application, it should be noted that for the orientation terms, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the indicated orientation and position relationships are based on the orientation or position relationships shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0032] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence.

[0033] One of the preferred embodiments of the present application is as Figures 1 to 12 shown. A locking type grounding device (i.e., a wiring clip) for a conductor includes a hook body 1, a lock hook assembly 5, a limit assembly 6, and a traction rope 3. A lifting hook 101 is provided at the top end of the hook body 1. The limit assembly 6 is disposed on the hook body 1 and cooperates with the lock hook assembly 5. The traction rope 3 is connected and cooperated with the lifting hook 101.

[0034] It can be understood that when hanging, the hook body 1 can be hung on the conductor 4 through the traction rope 3. Then, the traction rope 3 is lifted upward. At this time, the lock hook assembly 5 can perform a locking action under the drive of the conductor 4, and the limit assembly 6 can lock the lock hook assembly 5, so that the wiring clip is locked to the conductor 4, thereby realizing the reliable connection between the ground wire 2 and the conductor 4.

[0035] Furthermore, in order to facilitate the detachment between the wiring clip and the conductor 4 in the later stage, the end of the traction rope 3 has a first connection point and a second connection point. The first connection point is (fixedly) connected to the limit assembly 6, and the second connection point is connected and cooperated with the lifting hook 101 by hanging.

[0036] It should be noted that, as Figure 4 shown, the first connection point at the end of the towing rope 3 can be considered as the lowest point of the towing rope 3, and the second connection point can be considered to be at a position a certain distance above the first connection point. A suspension ring can be provided at the second connection point, and the second connection point is connected and cooperated with the lifting hook 101 through the suspension ring.

[0037] It can be understood that the grounding wire 2 is electrically connected to the terminal clamp. When hanging the grounding wire 2, first, the staff at a high position on the iron tower can lower the entire terminal clamp downward through the towing rope 3 so that the hook body 1 is hung on the wire 4. During the process of pulling and hanging the hook body 1 upward, the wire 4 will act on the locking hook assembly 5 on the hook body 1, and the locking hook assembly 5 will perform a locking action, and the limiting assembly 6 will lock the locking hook assembly 5, so that the locking hook assembly 5 maintains the locking action state at this time, thus enabling the terminal clamp to be locked on the wire 4 to achieve the grounding operation of the wire 4.

[0038] When it is necessary to remove the grounding wire 2, first lower the towing rope 3. Under the action of gravity, the second connection point (suspension ring) is disengaged from the lifting hook 101. At this time, when lifting the towing rope 3 upward, since the towing rope 3 is connected to the limiting assembly 6, the lifting of the towing rope 3 will trigger the limiting assembly 6 to act, that is, the original state where the limiting assembly 6 locks the locking hook assembly 5. At this time, the limiting assembly 6 will release the locking of the locking hook assembly 5. Then, under the extrusion of the wire 4, the locking hook assembly 5 will perform an unlocking action, so that the terminal clamp is disengaged from the wire 4, and thus the removal operation of the grounding wire 2 is completed.

[0039] It can be seen that during the installation and disassembly process of the terminal clamp, only one towing rope 3 needs to be operated to complete the hanging and removal of the entire grounding wire 2, which greatly simplifies the operation process and improves the work efficiency. In addition, since the entire operation process only requires one person to complete, the operation risk is also reduced and the operation safety is improved.

[0040] As a further description of the above embodiment: The locking hook assembly 5 includes a lock frame 501 and a lock rod 502. The lock rod 502 is rotatably installed on the hook body 1, and the lock frame 501 is installed on the lock rod 502. The lock rod 502 cooperates with the limiting assembly 6.

[0041] Specifically, as Figure 2As shown, the structures of the lock holder 501 and the hook body 1 are similar. Both are approximately "U"-shaped structures with the openings facing upward. The position where the lock holder 501 rotates is located on the (right) side of the hook body 1. In the initial hanging state: the opening of the hook body 1 is vertically upward, and the opening of the lock holder 501 is obliquely upward, but most of their openings are in a coincident state, thus facilitating the subsequent wire 4 to enter the opening for cooperation.

[0042] It can be understood that before hanging, as Figure 8 shown, the limiting component 6 cooperates with the first position 9 of the lock rod 502. At this time, the lock holder 501 is in the unlocked state (i.e., the above-mentioned initial hanging state). When hanging, as Figure 3 shown, during the upward pulling process of the lock holder 501, it will abut against the wire 4. Then, under the action of the wire 4, the lock holder 501 will rotate. Therefore, the openings of the lock holder 501 and the hook body 1 will cooperate to form a locking cavity for the wire 4, and thus the terminal clamp can be locked on the wire 4. Of course, at this time, the limiting component 6 can cooperate with the second position 10 of the lock rod 502, so that the lock holder 501 is in the locked state, as Figure 9 shown.

[0043] Of course, the present application does not limit the structural form of the limiting component 6. The following provides a specific embodiment for reference:

[0044] As Figure 8 shown, the limiting component 6 includes a limiting rod 601 and an elastic member 602 (such as a spring). The limiting rod 601 is vertically slidably mounted at the bottom end of the hook body 1 through the elastic member 602. Specifically, in order to enable the second end (top end) of the limiting rod 601 to better cooperate with the lock rod 502, a wedge-shaped block can be installed at the top end of the limiting rod 601, and the first end (bottom end) of the limiting rod 601 is (fixed) connected to the first connection point on the traction rope 3.

[0045] It can be understood that during the hanging process, the limiting rod 601 is always in an abutting and cooperating state with the lock rod 502 under the action of the elastic force. Specifically, as Figure 8 shown, in the initial state, the top end of the limiting rod 601 abuts and cooperates with the first position 9 of the lock rod 502. Then, under its limiting action, the lock holder 501 can be in the unlocked state; it should be known that at this time, the limiting rod 601 provides a "flexible" limit to the lock rod 502, that is, when the lock holder 501 is subjected to a relatively large external force, the lock holder 501 will still rotate forcibly. Before hanging, the entire terminal clamp generally will not be subjected to a relatively large external force. Therefore, the lock holder 501 can still maintain a stable initial state under the limiting action of the limiting rod 601.

[0046] When hanging, as Figure 2 shown, during the upward lifting process of the hook body 1, the wire 4 will cooperate with the lock frame 501. Therefore, the wire 4 will act on the lock frame 501. As the lifting force increases, the lock frame 501 will be forced to rotate, as Figure 3 shown, and then under the rotational traction of the lock frame 501, the wire 4 is located between the lock frame 501 and the hook body 1, thus realizing the installation and locking of the connection clamp; as Figure 9 shown, after the connection clamp is locked, at this time, the outer upper end of the limit rod 601 and the (left end) of the lock rod 502 are in a state of abutment; it should be known that at this time, the limit rod 601 provides a "rigid" limit to the lock rod 502, that is, no matter what force the lock frame 501 receives, the lock frame 501 will maintain the locked and engaged state, thus enabling the connection clamp to be stably locked on the wire 4.

[0047] During the hanging process of the connection clamp, the following problems may occur: as Figure 3 shown, if the grounding wire 2 is too close to the lifting hook 101, it will affect the disengagement operation process of the second connection point of the subsequent traction rope 3 and the lifting hook 101; and during the subsequent disengagement process, the hook body 1 needs to rotate. If the grounding wire 2 is directly installed on the hook body 1, there may be a phenomenon of knotting and entanglement.

[0048] Therefore, to solve the above technical problems, in one embodiment of the present application, as Figure 4 shown, a connection piece 7 (such as a copper nose) can be rotatably installed on the lock frame 501, and then the grounding wire 2 is connected to the connection piece 7, so as to realize the rotational installation between the grounding wire 2 and the lock frame 501. Therefore, when hanging, if the grounding wire 2 affects the disengagement between the traction rope 3 and the lifting hook 101, at this time, the grounding wire 2 can be rotationally adjusted along the connection clamp (lock frame 501) through the connection piece 7 to provide an avoidance space for the disengagement of the traction rope 3 and the lifting hook 101, thereby improving the flexibility of the operation.

[0049] When disengaging, as Figure 5 shown, that is, at this time, the entire connection clamp will rotate around the wire 4. That is to say, the connection clamp will rotate along the bottom end of the connection piece 7, and during this process, the grounding wire 2 will remain in a relatively stable state: the grounding wire 2 will not rotate with the connection clamp, and thus the phenomenon of knotting and entanglement will not occur.

[0050] It should be noted that in the above embodiments, the ground wire 2 is preferably rotatably mounted on the lock frame 501. Why is it not rotatably mounted on the hook body 1? Reason: Since the lifting hook 101 is provided on the hook body 1, and the lifting hook 101 needs to cooperate with the traction rope 3; if the ground wire 2 is also provided on the hook body 1, considering the balance of the entire terminal clamp and subsequent non-interference with the cooperation with the wire 4, the ground wire 2 needs to be provided at the right side position of the hook body 1, and thus on the same side as the lifting hook 101, that is, at this time, the installation points of the lifting hook 101 and the ground wire 2 are almost located in the same vertical direction. In this way, when laying and hanging, the ground wire 2 and the traction rope 3 are likely to be knotted and wound, thus affecting the hanging effect and efficiency. When it is provided on the lock frame 501, as Figure 2 shown, the installation point of the ground wire 2 can be offset from the lifting hook 101 in the vertical direction, so that there is a certain gap between the ground wire 2 and the traction rope 3, and thus the phenomenon of knotting and winding during the hanging process can be greatly reduced.

[0051] During the actual hanging process, since the ground wire 2 is thick and long, it has a certain weight, and the staff is also working at a high altitude; therefore, when setting the traction rope 3, a thinner rope can be selected for the traction rope 3, so as to reduce the overall gravity during hanging. In this way, on the one hand, the burden on the staff is reduced, and on the other hand, the sensitivity of the staff during operation can also be improved. Of course, when the traction rope 3 is set to be thinner, it cannot achieve a good load-bearing effect, that is to say, at this time, if the entire hanging process is only achieved by operating the traction rope 3, the traction rope 3 may break.

[0052] Therefore, to solve the above technical problems, during the actual operation process, the traction rope 3 and the ground wire 2 can be used in cooperation with each other. Specifically, as Figure 2 and Figure 12 shown, the rotation point of the terminal fitting 7 and the lock frame 501 is located at the end away from the opening of the lock frame 501. That is to say, at this time, when the ground wire 2 is pulled upward, the right end of the lock frame 501 rotates upward and the left end rotates downward (counterclockwise rotation), and thus can be regarded as a "lever" structure. It can be understood that during the hanging process, when the terminal clamp rises, under the action of the wire 4, the lock frame 501 can also rotate under the traction of the ground wire 2, that is, under the action of the two forces, so as to improve the effect and efficiency of closing and locking the terminal clamp.

[0053] It should be noted that there are two specific installation positions of the terminal fitting 7; the first one: as Figure 2As shown, the rotation point of the wiring member 7 and the lock bracket 501 is close to the rotation point between the lock bracket 501 itself and the hook body 1. Therefore, the gap between the wiring member 7 and the lifting hook 101 is small, which may affect the subsequent detachment of the traction rope 3 from the lifting hook 101. The second type: Figure 12 As shown, the rotation point of the wiring member 7 and the lock bracket 501 is far from the rotation point between the lock bracket 501 itself and the hook body 1. Therefore, the gap between the wiring member 7 and the lifting hook 101 is large, so it will not affect the subsequent detachment of the traction rope 3 from the lifting hook 101; at that time, due to the far distance between the two, the center of gravity will be dispersed, resulting in poor stability when the wiring clip is hung. However, both methods can meet the actual requirements, and those skilled in the art can make a choice according to the actual situation.

[0054] One embodiment of the present application, such as Figure 7 and Figure 9 As shown, a clamping assembly is further provided inside the hook body 1; after hanging, the clamping assembly can abut against the wire 4 so that the hook body 1 (wiring clip) is limited to the wire 4.

[0055] Specifically, the clamping assembly includes a pair of clip pieces 8, and the clip pieces 8 are elastically rotatably installed on both sides of the hook body 1 (through a torsion spring); that is, when hanging, the clip pieces 8 can abut against both sides of the wire 4 under the action of elastic force, and thus can play a role in limiting and clamping the wire 4 to ensure the stability and reliability of the wiring clip on the wire 4. The design of the clip pieces 8 not only improves the clamping force of the wiring clip, but also during the hanging and detachment processes, the clip pieces 8 can automatically adapt to the thickness change of the wire 4, thus ensuring the versatility and adaptability of the wiring clip.

[0056] The specific working steps of the present utility model are as follows:

[0057] S100: Connect one end of the grounding wire 2 to the wiring clip electrically, connect one end of the traction rope 3 to the bottom end of the wiring clip, and the one end of the traction rope 3 is also hung and matched with the lifting hook 101 at the top end of the wiring clip.

[0058] Specifically, that is, the grounding wire 2 is connected to the wiring member 7 (copper nose) on the wiring clip, the first connection point of the traction rope 3 is fixedly connected to the limiting rod 601, and the second connection point of the traction rope 3 is hung and matched with the lifting hook 101 through a suspension ring. Of course, since the wiring member 7 is rotatably installed, in the actual operation process, two workers can cooperate, that is, one worker holds the traction rope 3 and the other worker holds the grounding wire 2, and the two operate together to lower the wiring clip; however, it should be noted that during the process of lowering and hanging the wiring clip, as Figure 2As shown, let the relative angle between the grounding wire 2 and the towing rope 3 be α, where 0 ≤ α ≤ 60°.

[0059] Exemplarily, assuming α is zero degrees, it means that the grounding wire 2 and the towing rope 3 are parallel to each other. At this time, it is preferably to adopt the method of single-person operation, that is, a staff member holds the two ropes simultaneously for hanging and placing. If α takes 80° or 90° (i.e., greater than 60°), it should be noted that when hanging and placing, the towing rope 3 needs to be vertically lowered, because to ensure that the hook body 1 is in a vertical state to better cooperate with the wire 4. Then when two people lower the terminal clamp simultaneously, it is very easy to interfere with each other, that is, the staff member operating the grounding wire 2 is very likely to pull the terminal clamp, thereby changing the vertical state of the terminal clamp; at the same time, since the grounding wire 2 is closer to the horizontal position, when hanging and placing, the force for the staff member to rotate the lock frame 501 by pulling the grounding wire 2 will also be smaller, which will also affect the effect and efficiency when the terminal clamp is locked. Therefore, when performing the hanging and placing operation, the angle range of α is preferably between 0 and 60°.

[0060] S200: Operate the towing rope 3 to make the terminal clamp be hung and locked with the wire 4.

[0061] Specifically, taking one staff member as an example for operation, the staff member holds the towing rope 3 and the grounding wire 2 simultaneously to lower the grounding clamp, so that the grounding clamp is located directly below the wire 4. At this time, the openings of the grounding clamp (hook body 1) and the lock frame 501 both correspond to the wire 4. Then, the grounding clamp is lifted upward, so that the wire 4 enters the opening of the lock frame 501 (and of course also enters the opening of the grounding clamp). Then, the grounding clamp is lifted upward again, and the lock frame 501 will rotate under the action of the wire 4, as Figure 3 shown. Therefore, the openings of the lock frame 501 and the hook body 1 cooperate to form a locking cavity for the wire 4, so that the terminal clamp can be locked on the wire 4, and the connection between the grounding wire 2 and the wire 4 is completed.

[0062] It should be noted that after the above process, in order to prevent the towing rope 3 from falling and causing the second connection point to separate from the lifting hook 101, at this time, the towing rope 3 can be tightened (for example, the other end of the towing rope 3 is tied to the iron tower), so that the second connection point at one end of the towing rope 3 and the lifting hook 101 maintain a hanging and mating state; the purpose is also to prevent accidentally touching the towing rope 3 and then triggering the limit component 6, so as to stably maintain the stable locking state of the grounding clamp.

[0063] S300: After the grounding operation is completed, first operate the towing rope 3 to move downward and disengage from the lifting hook 101, and then operate the towing rope 3 to move upward to drive the terminal clamp to disengage from the wire 4.

[0064] Specifically, it is actually the process of removing the grounding clamp. At this time, first lower the towing rope 3, so that the second connection point (hanging ring) of the towing rope 3 moves downward under the action of gravity and separates from the lifting hook 101. Of course, during this process, the grounding wire 2 may approach the lifting hook 101, thereby interfering with the detachment of the towing rope 3. Therefore, as Figure 4 shown, the towing rope 3 can be operated to rotate and move away from the lifting hook 101, providing a movable avoidance space for the towing rope 3, and then the separation between the towing rope 3 and the lifting hook 101 can be achieved. Subsequently, pull the towing rope 3 upward, as Figure 4 and Figure 5 shown. Since the first connection point of the towing rope 3 is located at the bottom end of the grounding clamp, the grounding clamp will rotate counterclockwise under the pulling action of the towing rope 3, that is, change from the original state with the opening upward to the state with the opening downward, as Figure 6 shown. Continue to pull the towing rope 3 upward, and the limit rod 601 will separate from the lock rod 502 under the pulling action, thereby releasing the limit on the lock frame 501. At this time, under the extrusion action of the wire 4, the lock frame 501 will rotate (clockwise), and then be in the unlocking state, so that the grounding clamp can be detached from the wire 4, completing the entire grounding operation.

[0065] The above describes the basic principle, main features and advantages of the present application.
