DETAILED DESCRIPTION

[0024] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0025] See also Figure 1-7 The embodiment of the present invention provides a grounding wire clamp for a power line conductor end that is easy to hang, including: a wire clamp 10, a locking assembly 20 and a hand-held assembly 30; the locking assembly 20 includes a locking groove component 21 and a locking column component 22, the locking groove component 21 is arranged at the bottom end of the wire clamp 10, and the locking column component 22 is arranged at the front end of the hand-held assembly 30; the wire clamp 10 and the hand-held assembly 30 are detachably installed through the locking groove component 21 and the locking column component 22, so that the operator can hold the hand-held assembly 30 to send the wire clamp 10 to the power cable for hanging.

[0026] In this embodiment, the grounding wire clamp 10 mainly includes a wire clamp 10, a locking assembly 20 and a handheld assembly 30, wherein the locking assembly 20 includes a locking groove component 21 and a locking column component 22, the locking groove component 21 is arranged at the bottom end of the wire clamp 10, and the locking column component 22 is arranged at the front end of the handheld assembly 30, and the wire clamp 10 and the handheld assembly 30 can be detachably installed through the cooperation of the locking groove component 21 and the locking column component 22. In this way, when installing the grounding wire clamp 10, the operator only needs to stand in a safe place, install the wire clamp 10 on the handheld assembly 30, and then send the wire clamp 10 to the position where the grounding wire clamp 10 needs to be installed on the power cable through the handheld assembly 30 for installation, and the operator no longer needs to climb to a high place to install the wire clamp 10, which greatly reduces the safety hazards when the operator installs the wire clamp 10, which makes the wire clamp 10 more practical. Moreover, the grounding clamp 10 provided in this solution saves the time for operators to climb to a high place to install the clamp 10, which not only reduces the labor intensity of operators but also greatly improves the work efficiency of operators.

[0027] In one embodiment, the wire clamp 10 may mainly include: a first clamp body 11, a second clamp body 12, a torsion spring 13, a pin 14 and a trigger rod 15. The first clamp body 11 and the second clamp body 12 are rotatably connected through the pin 14. The torsion spring 13 is sleeved on the pin 14, and the two ends of the torsion spring 13 are respectively pressed against the inner sides of the first clamp body 11 and the second clamp body 12; a first through groove 111 is provided on the first clamp body 11, and a second through groove 121 is provided on the second clamp body 12. The fixed end of the trigger rod 15 is rotatably installed in the second through groove 121, and the free end extends in the direction of the first through groove 111, so as to open the upper end of the wire clamp 10 when it is pressed against the first clamp body 11, and close the upper end of the wire clamp 10 when it is detached from the first clamp body 11.

[0028] In this embodiment, the first clamp body 11 and the second clamp body 12 are connected by a pin 14 and a torsion spring 13 to form a wire clamp 10 structure, and the closing trigger of the wire clamp 10 is further realized by a trigger rod 15. In this way, the wire clamp 10 is opened before installation, and the free end of the trigger rod 15 is pressed against the first clamp body 11 to maintain the open state of the wire clamp 10. When the wire clamp 10 is sent to the power cable outlet where the ground wire needs to be hung through the handheld component 30, the power cable hits the trigger rod 15, so that the trigger rod 15 is detached from the first clamp body 11. At this time, the first clamp body 11 and the second clamp body 12 can clamp the power cable between the two, thereby realizing the ground wire hanging of the power cable.

[0029] Furthermore, in order to ensure that the trigger rod 15 can work, it can be easily pressed against the first clamp body 11, and can be separated from the first clamp body 11 when it is hit. In one embodiment, trapezoidal bosses 16 can be symmetrically arranged at the positions near the top on both sides of the first through slot 111, and the direction of the trapezoidal bosses 16 toward the inside of the wire clamp 10 is a plane, so that when the free end of the trigger rod 15 presses against the plane, the upper end of the wire clamp 10 is opened, and when the free end of the trigger rod 15 is separated from the plane, the upper end of the wire clamp 10 is closed.

[0030] In this embodiment, a trapezoidal boss 16 is provided in the first through slot 111, and the direction toward the inside of the wire clamp 10 is a plane, so that the trigger rod 15 can be against the plane, thereby realizing the opening of the first clamp body 11 and the second clamp body 12, that is, maintaining the opening state of the wire clamp 10. Moreover, the trapezoidal boss 16 should be provided in the first through slot 111 near the upper position, so that after the power cable enters the clamping part in the wire clamp 10, it can immediately hit the trigger rod 15, so that the trigger rod 15 is separated from the trapezoidal boss 16, and the power cable is clamped.

[0031] In addition, the position of the first through slot 111 on the first clamp 11 and the position of the second through slot 121 on the second clamp 12 should both be set as semicircular structures. In this way, the power cable can be clamped in the circular structure formed by the two semicircular structures, thereby clamping the power cable and further hanging the ground wire.

[0032] In one embodiment, in order to facilitate the fixed installation of the grounding wire on the wire clamp 10, it is considered to set a first mounting hole 112 at the lower side of the first clamp body 11. The first mounting hole 112 can be set as a threaded hole, so that the grounding wire can be fixedly installed at the position of the first mounting hole 112 by bolts.

[0033] After the power operation is completed, the wire clamp 10 installed on the power cable needs to be removed. Therefore, in order to facilitate the operator to remove the wire clamp 10, it is considered to set two second mounting holes 122 on the lower side of the second clamp body 12. Before installing the wire clamp 10, one end of the traction rope is fixedly installed on the two second mounting holes 122, and the other end is held by the operator. After the power operation is completed, the operator can hold the traction rope and pull the traction rope hard, so as to detach the wire clamp 10 from the power cable by applying force. In this way, the operator can remove the wire clamp 10 from a long distance, which is convenient, fast, time-saving and labor-saving.

[0034] The locking assembly 20 mainly includes a locking groove component 21 and a locking column component 22. In one embodiment, the locking groove component 21 may include a first fixing member 211 and a second fixing member 212, wherein the first fixing member 211 is fixedly disposed at the lower end of the first clamp body 11, and the second fixing member 212 is fixedly disposed at the lower end of the second clamp body 12; the first fixing member 211 and the second fixing member 212 are both semi-cylindrical shells, and when the upper end of the wire clamp 10 is opened, the two semi-cylindrical shells can form a complete hollow cylinder, and the first fixing member 211 and the second fixing member 212 are both provided with an "inverted L"-shaped through groove 213.

[0035] As for the locking column component 22, it may include a third fixing member 221 and two locking cylinders 222; the third fixing member 221 is fixedly installed on the front end of the handheld component 30, and the two locking cylinders 222 are symmetrically fixedly installed on the cylindrical surface of the third fixing member 221, so that the two locking cylinders 222 are respectively locked into the two "inverted L"-shaped through grooves 213 to realize the detachable installation of the wire clamp 10 and the handheld component 30.

[0036] In this embodiment, the "inverted L"-shaped through groove 213 on the first fixing member 211 and the second fixing member 212 should penetrate from the bottom of the first fixing member 211 and the second fixing member 212. In this way, when the wire clamp 10 is installed on the handheld component 30, since the trigger rod 15 is against the first clamp body 11 at this time, the wire clamp 10 is in an open state. Correspondingly, at this time, the first fixing member 211 and the second fixing member 212 are in a closed docking state, that is, in a state where two semi-cylindrical shells form a complete hollow cylinder. At this time, during installation, the two locking cylinders 222 enter the vertical grooves of the two "inverted L"-shaped through grooves 213 respectively, and then by rotating the handheld component 30, the locking cylinder 222 can be rotated to the other side of the "inverted L"-shaped through groove 213, that is, rotated to the horizontal groove, to prevent the locking groove component 21 and the locking column component 22 from being separated. When the wire clamp 10 is delivered to the power cable and causes the power cable to hit the trigger rod 15, the trigger rod 15 disengages from the first clamp body 11, the wire clamp 10 closes, and at the same time the first fixing member 211 and the second fixing member 212 open, and the locking groove component 21 and the locking column component 22 separate, thereby realizing the separation of the wire clamp 10 and the handheld component 30.

[0037] Of course, in one embodiment, in order to further ensure the locking firmness of the locking cylinder 222 and the "inverted L"-shaped groove 213, it is considered to set a semicircular groove at the end of the horizontal groove of the "inverted L"-shaped groove 213, so that the locking cylinder 222 can fit into the groove, further improving the locking firmness.

[0038] As for the handheld component 30, in one embodiment, the handheld component 30 can be composed of several cylindrical shells that are telescopically connected, and a fastening component 31 is provided between two adjacent cylindrical shells. In this way, the length of the handheld component 30 can be flexibly adjusted according to the height of the power cable to be hung for the ground wire. Moreover, the two adjacent cylindrical shells can be controlled by fasteners to avoid arbitrary expansion and contraction between the corresponding two cylindrical shells. In this way, in the process of sending the wire clamp 10 to the power cable to be hung for the ground wire through the handheld component 30, and in the process of controlling the collision of the trigger rod 15 with the power cable, the handheld component 30 is avoided from being expanded and contracted at will, which affects the operation.

[0039] Of course, in order to ensure the safety of the operators, in practice, a handle 32 made of insulating material is provided on the bottom cylindrical shell of the handheld component to improve the safety of the operators.

[0040] When the grounding wire clamp 10 for the conductor end of the line in the store provided by the present invention is implemented, the operator first fixes the grounding wire and the traction rope on the wire clamp 10, then forcibly opens the first clamp body 11 and the second clamp body 12, and makes the trigger rod 15 rest on the trapezoidal boss 16 of the first clamp body 11 to keep the wire clamp 10 in the open state. Further, the locking cylinder 222 of the locking column part 22 at the front end of the handheld component 30 is inserted into the "inverted L"-shaped through groove 213 of the locking groove part 21, and the handheld component 30 is rotated so that the locking cylinder 222 is located in the groove of the horizontal groove. Then, the other end of the traction rope is fixed to an object around the operator, or held by the operator. The operator adjusts the length of the handheld component 30 according to the height and distance of the power cable to be hung with the ground wire, and tightens the fastener, and then the operator holds the handheld component 30 tightly to send the wire clamp 10 to the power cable, so that the power cable enters from the opening of the wire clamp 10 and hits the trigger rod 15. The trigger rod 15 is disengaged, the first clamp body 11 and the second clamp body 12 are closed, and the wire clamp 10 is clamped on the power cable. At the same time, the first fixing member 211 and the second fixing member 212 are opened, the locking groove component 21 and the locking column component 22 are separated, that is, the handheld component 30 and the wire clamp 10 are separated, and the staff performs the power operation. After the power operation is completed, the staff holds the traction rope and pulls it hard to separate the wire clamp 10 from the power cable.

[0041] The modules or units in the device of the embodiment of the present invention can be combined, divided and deleted according to actual needs. The above disclosure is only the preferred embodiment of the present invention, and of course it cannot be used to limit the scope of the rights of the present invention. Those skilled in the art can understand that all or part of the processes of the above embodiment are implemented, and the equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
