DETAILED DESCRIPTION
[0031] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0032] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.
[0033] 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 are not necessarily used to describe a specific order or sequence.
[0034] One of the preferred embodiments of the present application is as follows: Figures 1 to 12 As shown, a grounding device for a conductor includes a wiring clamp, and the wiring clamp includes a hook body 1, a locking hook assembly 5, a limiting assembly 6 and a traction rope 3. A lifting hook 101 is arranged at the top of the hook body 1, the locking hook assembly 5 is movably arranged on the hook body 1, the limiting assembly 6 is arranged on the hook body 1 and cooperates with the locking hook assembly 5, and the end of the traction rope 3 has a first connection point and a second connection point, wherein the first connection point is (fixedly) connected to the limiting assembly 6, and the second connection point is hooked and cooperated with the lifting hook 101.
[0035] It should be noted that if Figure 4As shown, the first connection point at the end of the traction rope 3 can be considered as the bottom end (point) of the traction rope 3, and the second connection point can be considered to be at a distance above the first connection point. A suspension ring can be provided at the second connection point, and the second connection point is hung and matched with the suspension ring and the lifting hook 101.
[0036] It can be understood that the grounding wire 2 is electrically connected to the wiring clamp. When hanging the grounding wire 2, the staff can first use the traction rope 3 to lower the entire wiring clamp at a high position on the tower, so that the hook body 1 is hung on the conductor 4. In the process of pulling the hook body 1 upward for hanging, the conductor 4 will act on the lock hook assembly 5 on the hook body 1, and the lock hook assembly 5 will perform a locking action, and the limit assembly 6 will lock the lock hook assembly 5, thereby keeping the lock hook assembly 5 in the locked action state at this time, so that the wiring clamp can be locked on the conductor 4 to achieve the grounding operation of the conductor 4.
[0037] When the grounding wire 2 needs to be removed, the traction rope 3 is first moved downward, and under the action of gravity, the second connection point (suspension ring) is separated from the lifting hook 101. At this time, the traction rope 3 is lifted upward. Since the traction rope 3 is connected to the limiting component 6, the pulling of the traction rope 3 will trigger the limiting component 6 to act, that is, the limiting component 6 originally locked the locking hook component 5. At this time, the limiting component 6 will release the lock of the locking hook component 5, and then the locking hook component 5 will be unlocked under the squeezing action of the wire 4, so that the wiring clamp will be separated from the wire 4, and the removal of the grounding wire 2 is completed.
[0038] It can be seen that during the installation and removal of the wiring clamp, only one traction rope 3 needs to be operated to complete the installation and removal of the entire grounding wire 2, which greatly simplifies the operation process and improves work efficiency. In addition, since the entire operation process only requires one person to complete, it also reduces the operation risk and improves the operation safety.
[0039] As a further description of the above embodiment: the lock hook assembly 5 includes a lock frame 501 and a lock rod 502 , the lock rod 502 is rotatably mounted on the hook body 1 , and the lock frame 501 is mounted on the lock rod 502 , and the lock rod 502 cooperates with the limiting assembly 6 .
[0040] Specifically, Figure 2As shown, the structures of the lock frame 501 and the hook body 1 are similar, both of which are approximately "U"-shaped structures with openings facing upward, and the rotation position of the lock frame 501 is located at the (right) side position 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 frame 501 is obliquely upward, but most of the openings of the two are in an overlapping state, which makes it easy for the subsequent wire 4 to enter the opening for cooperation.
[0041] It is understandable that before hanging, Figure 8 As shown, the limiting assembly 6 cooperates with the first position 9 of the locking rod 502, and the locking frame 501 is in an unlocked state (i.e., the initial hanging state mentioned above). Figure 3 As shown, the lock frame 501 will be against the wire 4 during the upward pulling process, and then the lock frame 501 will rotate under the action of the wire 4, so the opening of the lock frame 501 will cooperate with the opening of the hook body 1 to form a locking cavity for the wire 4, so that the wiring clamp can be locked on the wire 4. Of course, at this time, the limit assembly 6 can cooperate with the second position 10 of the lock rod 502, so that the lock frame 501 is in a locked state, as shown in FIG. Fig. 9 shown.
[0042] Of course, the present application does not limit the structural form of the limit assembly 6. A specific embodiment is provided below for reference:
[0043] like Figure 8 As shown, the limiting assembly 6 includes a limiting rod 601 and an elastic member 602 (such as a spring), and the limiting rod 601 is vertically slidably installed at the bottom end of the hook body 1 through the elastic member 602. Specifically, in order to make the second end (top end) of the limiting rod 601 better cooperate with the locking rod 502, a wedge 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 (fixedly) connected to the first connection point on the traction rope 3.
[0044] It is understandable that during the hanging process, the limit rod 601 is always in a state of abutment with the lock rod 502 under the action of elastic force. Figure 8 As shown, in the initial state, the top of the limit rod 601 and the first position 9 of the lock rod 502 are matched, and then the lock frame 501 can be in the unlocked state under the limit force; it should be known that the limit rod 601 is a "flexible" limit on the lock rod 502 at this time, that is, under the action of a large external force on the lock frame 501, the lock frame 501 will still be forced to rotate. Before hanging, the entire wiring clamp is generally not subjected to a large external force, so the lock frame 501 can still maintain a stable initial state under the limit action of the limit rod 601.
[0045] When hanging, if Figure 2 As shown, during the upward lifting process of the hook body 1, the wire 4 will cooperate with the lock frame 501, so the wire 4 will act on the lock frame 501, and as the lifting force becomes greater and greater, the lock frame 501 will be forced to rotate, as shown in FIG. Figure 3 As shown, the wire 4 is located between the lock frame 501 and the hook body 1 under the rotation of the lock frame 501, thereby achieving installation and locking of the connecting clip; Fig. 9 As shown, after the wiring clamp is locked, the outer upper end of the limit rod 601 and the (left end) of the locking rod 502 are in abutment with each other; it should be known that at this time, the limit rod 601 is a "hard" limit on the locking rod 502, that is, no matter what force is applied to the locking frame 501, the locking frame 501 will remain in a locked and engaged state, thereby allowing the wiring clamp to be stably locked on the wire 4.
[0046] In the process of hanging the wiring clip, the following problems may occur: Figure 3 As shown, if the grounding wire 2 and the lifting hook 101 are too close, it will affect the subsequent disengagement operation process of the second connection point of the traction rope 3 and the lifting hook 101; and in the subsequent disengagement process, the hook body 1 needs to rotate. If the grounding wire 2 is directly installed on the hook body 1, knotting and entanglement may occur.
[0047] Therefore, in order to solve the above technical problems, one of the embodiments of the present application is as follows: Figure 4 As shown, a connecting 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 connecting piece 7, so that the rotatable installation between the grounding wire 2 and the lock frame 501 can be realized. Therefore, when hanging, if the grounding wire 2 affects the separation between the traction rope 3 and the lifting hook 101, the grounding wire 2 can be rotated and adjusted along the connecting clamp (lock frame 501) through the connecting piece 7 to provide an escape space for the traction rope 3 to separate from the lifting hook 101, thereby improving the flexibility of operation.
[0048] When disengaging, Figure 5 As shown, at this time, the entire wiring clamp will rotate around the wire 4, that is, the wiring clamp will rotate along the bottom end of the wiring 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 wiring clamp, and thus will not become tangled.
[0049] It should be noted that, in the above embodiment, the grounding wire 2 is preferably rotatably installed on the locking frame 501. Why not rotatably install it on the hook body 1? Reason: Since the lifting hook 101 is set on the hook body 1, and the lifting hook 101 needs to cooperate with the traction rope 3; if the grounding wire 2 is also set on the hook body 1, and considering the balance of the entire wiring clamp and the subsequent non-influence on the coordination with the conductor 4, the grounding wire 2 needs to be set on the right side of the hook body 1, and then on the same side as the lifting hook 101, that is, at this time, the installation points of the lifting hook 101 and the grounding wire 2 are almost in the same vertical direction. In this way, when the wire is laid and hung, the grounding wire 2 and the traction rope 3 will easily become tangled, thereby affecting the hanging effect and efficiency. When it is set on the locking frame 501, such as Figure 2 As shown, the installation point of the grounding wire 2 can be offset from the lifting hook 101 in the vertical direction, so that a certain gap is left between the grounding wire 2 and the traction rope 3, thereby greatly reducing the phenomenon of knotting and entanglement during the hanging process.
[0050] In the actual hanging process, since the grounding wire 2 is thick and long, and thus has a certain weight, and the staff is also working at 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 gravity during the entire hanging process, which can reduce the burden on the staff and improve the sensitivity of the staff during operation. Of course, when the traction rope 3 is set thinner, it cannot play a good load-bearing effect, that is, if the entire hanging process is realized only by operating the traction rope 3, the traction rope 3 may break.
[0051] Therefore, in order to solve the above technical problems, in the actual operation process, the traction rope 3 and the grounding wire 2 can be used in conjunction with each other. Figure 2 and Fig.12 As shown, the rotation point of the connecting piece 7 and the locking frame 501 is located at the end away from the opening of the locking frame 501, that is, when the grounding wire 2 is pulled upward, the right end of the locking frame 501 rotates upward and the left end rotates downward (counterclockwise), which can be regarded as a "lever" structure. It can be understood that during the hanging process, when the wiring clamp rises, the locking frame 501 is under the action of the wire 4, and the locking frame 501 can also rotate under the traction of the grounding wire 2, that is, under the action of both forces, thereby improving the effect and efficiency of closing and locking the wiring clamp.
[0052] It should be noted that there are two specific installation positions of the terminal block 7; the first one is as follows: Figure 2As shown, the rotation point of the connecting piece 7 and the lock frame 501 is close to the rotation point between the lock frame 501 and the hook body 1, so the gap between the connecting piece 7 and the lifting hook 101 is small, which may affect the subsequent separation of the traction rope 3 from the lifting hook 101. The second type: Fig.12 As shown, the rotation point of the connecting piece 7 and the lock frame 501 is far away from the rotation point between the lock frame 501 and the hook body 1, so the gap between the connecting piece 7 and the lifting hook 101 is large, so that the subsequent separation of the traction rope 3 from the lifting hook 101 will not be affected; at that time, because the two are far apart, the center of gravity will be dispersed, resulting in poor stability of the connecting clip when hanging. However, both methods can meet actual needs, and technicians in this field can choose according to actual conditions.
[0053] One of the embodiments of the present application is as follows: Figure 7 and Fig. 9 As shown, the two sides of the hook body 1 are elastically rotatably mounted with clips 8 (through torsion springs); that is, when hanging, the clips 8 can be pressed against the two sides of the wire 4 under the action of elastic force, and then can play a role of limiting and clamping the wire 4 to ensure the stability and reliability of the wiring clamp on the wire 4. The design of the clip 8 not only improves the clamping force of the wiring clamp, but also in the process of hanging and detaching, the clip 8 can automatically adapt to the thickness change of the wire 4, thereby ensuring the versatility and adaptability of the wiring clamp.
[0054] Another aspect of the present application provides a method for grounding a wire, which specifically includes the following steps:
[0055] S100: One end of the grounding wire 2 is electrically connected to the wiring clamp, one end of the traction rope 3 is connected to the bottom end of the wiring clamp, and one end of the traction rope 3 is also hooked and matched with the lifting hook 101 at the top end of the wiring clamp.
[0056] Specifically, the grounding wire 2 is connected to the terminal piece 7 (copper nose) on the terminal clamp, the first connection point of the traction rope 3 is fixedly connected to the limit rod 601, and the second connection point of the traction rope 3 is hung and matched through the hanging ring and the lifting hook 101. Of course, since the terminal piece 7 is rotatably installed, two workers can work together during the actual operation, that is, one worker holds the traction rope 3 and the other worker holds the grounding wire 2, and the two work together to lower the terminal clamp; however, it should be noted that during the process of lowering the terminal clamp, if Figure 2 As shown, we assume that the relative angle between the grounding wire 2 and the traction rope 3 is α, where 0≤α≤60°.
[0057] For example, assuming that α is zero degrees, it means that the grounding wire 2 and the traction rope 3 are parallel. In this case, it is preferred to use a single-person operation method, that is, one staff member holds the two ropes at the same time for hanging. If α is 80° or 90° (i.e., greater than 60°), it should be known that the traction rope 3 needs to be lowered vertically when hanging, because the hook body 1 must be in a vertical state to cooperate with the wire 4. At this time, when two people lower the wiring clamp at the same time, it will be easy to interfere with each other, that is, the staff member operating the grounding wire 2 can easily pull the wiring clamp, thereby changing the vertical state of the wiring clamp; at the same time, because the grounding wire 2 is closer to the horizontal position, when hanging, the staff member will use the traction of the grounding wire 2 to make the locking frame 501 rotate. The force will also be smaller, which will also affect the effect and efficiency of the wiring clamp when locking. Therefore, when performing the hanging operation, the angle range of α is preferably between 0-60°.
[0058] S200: Operate the traction rope 3 so that the wiring clamp is hooked and locked with the conductor 4.
[0059] Specifically, we take a worker as an example to explain the operation. The worker holds the traction rope 3 and the grounding wire 2 at the same time to hang the grounding clamp down, so that the grounding clamp is located directly below the wire 4. At this time, the opening of the grounding clamp (hook body 1) and the opening of the lock frame 501 correspond to the wire 4. Then, the grounding clamp is pulled upward to make the wire 4 enter the opening of the lock frame 501 (of course, it also enters the opening of the grounding clamp). Then, the grounding clamp is pulled upward, and the lock frame 501 rotates under the action of the wire 4. Figure 3 As shown, the opening of the lock frame 501 cooperates with the opening of the hook body 1 to form a locking cavity for the wire 4, so that the wiring clamp can be locked on the wire 4 to complete the overlap between the ground wire 2 and the wire 4.
[0060] It should be noted that after the above process, in order to prevent the traction rope 3 from falling and causing the second connection point to separate from the lifting hook 101, the traction rope 3 can be tightened at this time (for example, the other end of the traction rope 3 is tied to the iron tower) so that the second connection point at one end of the traction rope 3 and the lifting hook 101 maintain a hooked and matched state; its purpose is also to prevent the traction rope 3 from being accidentally touched in the future and triggering the limit assembly 6, so as to stably maintain the stable locking state of the grounding clamp.
[0061] S300: After the grounding operation is completed, the traction rope 3 is first operated to move downward and separate from the lifting hook 101, and then the traction rope 3 is operated to move upward to drive the connection clamp to separate from the conductor 4.
[0062] Specifically, it is actually the process of removing the grounding clamp. At this time, the traction rope 3 is first suspended, so that the second connection point (hanging ring) of the traction rope 3 moves down under the action of gravity and separates from the lifting hook 101. Of course, in this process, the grounding wire 2 may approach the lifting hook 101, thereby interfering with the detachment of the traction rope 3. Figure 4 As shown, the traction rope 3 can be operated to rotate and move away from the lifting hook 101, providing the traction rope 3 with a movable escape space, thereby enabling the traction rope 3 to be separated from the lifting hook 101. Then, the traction rope 3 is pulled upward, as shown in FIG. Figure 4 and Figure 5 As shown, since the first connection point of the traction rope 3 is located at the bottom end of the grounding clamp, the grounding clamp will rotate counterclockwise under the pulling action of the traction rope 3, that is, it will change from the original upward opening state to the downward opening state, as shown in FIG. Figure 6 As shown, the traction rope 3 is continuously pulled upward, and the limit rod 601 will be separated from the locking rod 502 under the pulling action, thereby releasing the limit on the lock frame 501. At this time, the lock frame 501 will rotate (clockwise) under the squeezing action of the wire 4, and then be in an unlocked state, so that the grounding clamp can be separated from the wire 4, completing the entire grounding operation.
