Description

Grounding wire clamp and grounding wire erecting device

Technical Field

The application relates to the technical field of auxiliary ground wire erection tools, in particular to a ground wire clamp and a ground wire erection device.

Background

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

In the work of a power system, the erection of the ground wire is an important link for guaranteeing the personal safety of operators, and when the ground wire is erected, the operators usually finish the erection of the ground wire by means of a ground wire clamp.

In the related art, the ground clips are broadly classified into an overhead bare conductor ground clip and a busbar ground clip according to the applicable objects. The overhead bare conductor grounding wire clamp is suitable for erecting a grounding wire on the overhead bare conductor and clamps the bare conductor by means of two clamping pieces arranged inside the hook-shaped bending part; the busbar grounding wire clamp is suitable for erecting a grounding wire on a busbar in a switch cabinet or on the low-voltage side of the main transformer, and clamps the busbar by means of cooperation between a fixed contact and a movable contact capable of moving towards the fixed contact.

It can be seen that the clamping principle adopted by the overhead bare conductor grounding clamp and the busbar grounding clamp is quite different, so that the two cannot be mutually rotated. However, in actual work, an operator who goes out often delays the working time due to the fact that the operator carries the ground wire clamp with the fault, and in order to avoid such a situation, an effective way is to carry the overhead bare conductor ground wire clamp and the busbar ground wire clamp by the operator at the same time, but this way increases the burden of the operator.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described in connection with the following detailed description.

Referring to fig. 1 and 2, some embodiments of the present application provide a ground clip 100, wherein fig. 1 shows a schematic structural view of the ground clip 100, and fig. 2 shows a schematic structural view of a bending part 10 in the ground clip 100. Specifically, the ground clip 100 includes a bending member 10, a clamping member 20, and an operating member 30.

In some embodiments of the present application, the curved member 10 is generally hook-shaped, and in particular, the curved member 10 includes a first upright portion 11, a curved portion 12, and a second upright portion 13. As shown in fig. 2, the first vertical portion 11 and the second vertical portion 13 are disposed opposite to each other, and the bent portion 12 is used to connect the first vertical portion 11 and the second vertical portion 13, for example, two ends of the bent portion 12 may be connected to top ends of the first vertical portion 11 and the second vertical portion 13, respectively, so as to define a clamping cavity 15 with a downward opening 14 by the first vertical portion 11, the bent portion 12, and the second vertical portion 13, and the length of the second vertical portion 13 is greater than that of the first vertical portion 11.

The clamping member 20 is configured to clamp both the bare conductor and the busbar, and specifically the clamping member 20 includes two clips 21 and a movable contact 22. As shown in fig. 1, the two clamping pieces 21 are disposed in the clamping cavity 15, and a clamping channel for clamping the bare conductor is formed between the two clamping pieces, so that the bare conductor can be clamped by the two clamping pieces 21 only by allowing the bare conductor to enter the clamping channel between the two clamping pieces 21 from the opening 14 in actual use.

The movable contact 22 is disposed below the opening 14 and aligned with the opening 14, so that when the ground clip 100 is used as a busbar ground clip, the whole bending part 10 together with the two clips 21 serves as a stationary contact that cooperates with the movable contact 22. At this time, the operating member 30 is connected to the second vertical portion 13 and located below the moving contact 22, and the operating member 30 is used to bring the moving contact 22 close to or away from the opening 14.

In this way, when the busbar needs to be clamped, only the busbar needs to be located between the moving contact 22 and the opening 14 of the bending member 10, and then the moving contact 22 can be close to the opening 14 by the operating member 30, so that the busbar is clamped between the moving contact 22 and the opening 14.

Therefore, the grounding wire clamp 100 provided by the application can be used as an overhead bare wire grounding wire clamp and a busbar grounding wire clamp by arranging the clamping structure capable of clamping the bare wire and the busbar, so that the practicability of the grounding wire clamp 100 is greatly improved, an operator can erect the grounding wire 200 on the bare wire or the busbar by carrying only one grounding wire clamp 100 in actual work, and the situation that the operator delays the operation time due to carrying the wrong grounding wire clamp 100 is effectively avoided while the burden of the operator is reduced.

In order to improve the reliability of the ground clip 100 when used as a busbar ground clip and clamping a busbar, in some embodiments of the present application, as shown in fig. 4, the bottom ends of the first vertical portion 11 and the bottom ends of the two clamping pieces 21 that form the bending member 10 are in the same horizontal plane, so that the contact area with the busbar can be increased when clamping the busbar, so that the busbar can be reliably clamped between the movable contact 22 and the opening 14 of the bending member 10.

In order to improve the reliability of the grounding clip 100 when used as an overhead bare conductor grounding clip and clamping bare conductors, in some embodiments of the present application, two clamping pieces 21 are each in an arc structure and are hinged to a first vertical portion 11 and a second vertical portion 13, respectively, for example, as shown in fig. 1, one clamping piece 21 is hinged to the first vertical portion 11 near its bottom end, and the other clamping piece 21 is hinged to the second vertical portion 13 near its bottom end, so that a clamping channel formed between the two clamping pieces 21 is gradually narrowed from bottom to top.

At this time, the clamping member 20 may further include first elastic members 23 in one-to-one correspondence with the clips 21, and the first elastic members 23 are connected between the clips 21 and the corresponding vertical portions. For example, the first elastic member 23 may be a spring, and for the clip 21 hinged to the first vertical portion 11, the first elastic member 23 corresponding to the clip 21 is connected between the clip 21 and the first vertical portion 11; accordingly, for the clip 21 hinged to the second vertical portion 13, the first elastic member 23 corresponding to the clip 21 is connected between the clip 21 and the second vertical portion 13.

Based on this setting, in the initial state, the first elastic members 23 corresponding to the two clamping pieces 21 are in a natural elongation state, when the bare conductor needs to be clamped, the bare conductor is led to enter the clamping channel formed between the two clamping pieces 21 from the opening 14, and in the process that the bare conductor moves upwards relative to the two clamping pieces 21, the bare conductor applies extrusion force to the two clamping pieces 21 due to the gradual narrowing of the clamping channel, so that the first elastic members 23 corresponding to the clamping pieces 21 are compressed, and meanwhile, the first elastic members 23 can also apply extrusion force to the corresponding clamping pieces 21, so that the bare conductor can be reliably clamped between the two clamping pieces 21.

On this basis, when the ground clip 100 needs to be removed from the bare conductor, the ground clip 100 is typically pushed upwards to withdraw the bare conductor from between the two clamping pieces 21, however, in this process, the bare conductor may be influenced by the clamping forces of the two clamping pieces 21 to move synchronously with the ground clip 100, so that the bare conductor cannot withdraw smoothly from between the two clamping pieces 21.

For this reason, in some embodiments of the present application, as shown in fig. 2, the bent portion 12 constituting the bending member 10 is provided with escape grooves 16 penetrating both upper and lower surfaces thereof. At this time, the ground clip 100 may further include an opening and closing assembly 40, and the opening and closing assembly 40 is used to separate the two clips 21 from each other by a sufficient distance when the ground clip 100 needs to be removed from the bare wire, so that the bare wire can be smoothly withdrawn from between the two clips 21.

Specifically, the opening and closing assembly 40 may include two opening and closing units 41 and a driving unit 42, where the two opening and closing units 41 are in one-to-one correspondence with the two clamping pieces 21, that is, one opening and closing unit 41 is matched with one clamping piece 21, and at this time, the avoiding groove 16 provided on the bending portion 12 may also be in one-to-one correspondence with the opening and closing unit 41.

Further, as shown in fig. 3, for the single opening and closing unit 41, the opening and closing unit 41 includes a rotating shaft 411 and a pulling rope 412, wherein the rotating shaft 411 is rotatably disposed in the avoiding slot 16, the pulling rope 412 is wound on the rotating shaft 411 and connected to the corresponding clamping piece 21, and the driving unit 42 is used for rotating the rotating shafts 411 of the two opening and closing units 41 in opposite directions.

So configured, when the ground clip 100 needs to be removed from the bare conductor, the rotating shafts 411 of the two opening and closing units 41 are rotated in opposite directions by the driving unit 42, at this time, the pulling ropes 412 of the two opening and closing units 41 will gradually wind around the corresponding rotating shafts 411, as shown by the arrow located beside the clip 21 in fig. 4 (the arrow represents the moving direction of the clip 21), the pulling ropes 412 will apply a pulling force to the corresponding clip 21 to force the clip 21 to rotate around the hinge point where the clip 21 is hinged to the corresponding vertical portion, so that the two clips 21 are separated from each other by a sufficient distance under the action of the pulling ropes 412 of the corresponding opening and closing units 41, in this process, the bare conductor will not be clamped by the two clips 21, and the bare conductor can be smoothly withdrawn from between the two clips 21.

In order to enable the rotation shafts 411 of the two opening and closing units 41 to rotate in opposite directions by means of the driving unit 42, in some embodiments of the present application, the opening and closing units 41 may further include a rotation pulley 413, as shown in fig. 3, the rotation pulley 413 being provided at the front side of the bending portion 12 and being in driving connection with the rotation shaft 411, that is, the rotation pulley 413 being rotatable coaxially with the rotation shaft 411.

At this time, the driving unit 42 may include a slider 421, a driving string 422, and a pulling string 423. As shown in fig. 4, the sliding block 421 is slidably engaged with the second vertical portion 13, so that the sliding block 421 can slide along the length direction of the second vertical portion 13, for example, a sliding groove extending along the length direction of the second vertical portion 13 may be formed in the second vertical portion 13, and the sliding block 421 is slidably disposed in the sliding groove to implement the sliding engagement between the sliding block 421 and the second vertical portion 13.

The driving ropes 422 are in one-to-one correspondence with the opening and closing units 41, that is, one driving rope 422 is engaged with one opening and closing unit 41. For the single driving rope 422, one end of the driving rope 422 is connected to the slider 421, the other end of the driving rope 422 is wound around the rotating pulleys 413 of the corresponding opening and closing units 41, and winding directions of the driving rope 422 wound around the rotating pulleys 413 of the two opening and closing units 41 are opposite. For example, as shown in fig. 4, the driving rope 422 corresponding to the opening and closing unit 41 near the second vertical portion 13 may be wound around the rotating pulley 413 of the opening and closing unit 41 counterclockwise, and correspondingly, the driving rope 422 corresponding to the opening and closing unit 41 near the first vertical portion 11 may be wound around the rotating pulley 413 of the opening and closing unit 41 clockwise.

The pull cord 423 is used for driving the slider 421 to slide along the length direction of the second vertical portion 13, specifically, one end of the pull cord 423 is connected to the slider 421, and the other end of the pull cord 423 extends vertically downward.

So configured, when it is required to rotate the rotation shafts 411 of the two opening and closing units 41 in opposite directions, it is only necessary for an operator to stand on the ground and pull the pull cord 423, at this time, the slider 421 will slide vertically downward under the action of the pull cord 423 to drive the two driving ropes 422 to move through the slider 421, in the process, the rotation pulleys 413 of the two opening and closing units 41 will rotate under the action of friction force with the corresponding driving ropes 422, and since the winding directions of the driving ropes 422 wound on the rotation pulleys 413 of the two opening and closing units 41 are opposite, the rotation shafts 411 of the two opening and closing units 41 can be driven to rotate in opposite directions by the rotation pulleys 413 of the two opposite rotation directions, as seen by the arrow (which represents the rotation direction of the rotation pulleys 413) at the rotation pulleys 413 of the two opening and closing units 41 shown in fig. 4.

Second, in some embodiments of the present application, the driving unit 42 may further include a limit structure (not shown) for locking the position of the slider 421 when the slider 421 is slid to a predetermined position. For example, the predetermined position may be a position where the slider 421 is located when the two clips 21 are separated from each other by a sufficient distance so that the bare conductor can be smoothly withdrawn from between the two clips 21, and the limiting structure may be, but not limited to, a form of a buckle and a slot, for example, the limiting structure may include a buckle provided on a sliding path of the slider 421 and a slot provided on the slider 421, and when the slider 421 slides to the predetermined position, the buckle just can be snapped into the slot on the slider 421, thereby achieving locking of the position of the slider 421.

In addition, in some embodiments of the present application, with continued reference to fig. 4, the opening and closing assembly 40 may further include a positioning ring 43 disposed at the front side of the bending portion 12, the positioning ring 43 being located between the rotating pulleys 413 of the two opening and closing units 41, and at this time, the driving rope 422 corresponding to the opening and closing unit 41 near the first vertical portion 11 passes through the positioning ring 43, and the driving rope 422 corresponding to the opening and closing unit 41 near the first vertical portion 11 can be effectively prevented from being suspended by the positioning ring 43.

To achieve that the moving contact 22 is brought closer to or farther from the opening 14 of the bending member 10 by means of the operating member 30, in some embodiments of the present application the moving contact 22 is in sliding engagement with the second vertical portion 13 such that the moving contact 22 can slide in the length direction of the second vertical portion 13. For example, as shown in fig. 1, the sliding fit of the moving contact 22 with the second vertical portion 13 may be achieved by providing a sliding portion extending in the length direction thereof on the second vertical portion 13 and providing a slide groove on the moving contact 22 that is adapted to the sliding portion.

At this time, the operation member 30 may include a fixed seat 31 and a screw 32, as shown in fig. 1, the fixed seat 31 is connected to the second vertical portion 13, the top end of the screw 32 penetrates through the fixed seat 31 and is movably connected to the moving contact 22, for example, the top end of the screw 32 may be rotatably connected to the moving contact 22, and the screw 32 is in threaded connection with the fixed seat 31. In this way, when the movable contact 22 needs to be close to or far from the opening 14 of the bending part 10, only the screw rod 32 needs to be screwed, and the operation is simple and convenient.

In some embodiments of the present application, with continued reference to fig. 1, the operating member 30 may further include a connecting sleeve 33, the connecting sleeve 33 being disposed at the bottom end of the screw 32. At this time, the ground clip 100 may further include a hand-held lever 50 that can be connected to the connection sleeve 33, and by providing the hand-held lever 50, an operator can stand on the ground to perform a corresponding operation using the ground clip 100.

However, in the known ground clip 100, the hand-held rod 50 for the operator to hold is usually a rod, and in the case of the rod, the rod is usually connected to the connecting sleeve 33 by a threaded connection, in this case, when the screw 32 needs to be screwed, the hand-held rod 50 is usually directly rotated, and in this process, the hand-held rod 50 may rotate relative to the connecting sleeve 33 and gradually separate from the connecting sleeve 33, so that the screw 32 cannot be smoothly driven to rotate.

To this end, in some embodiments of the present application, the manner of connection between the hand lever 50 and the connecting sleeve 33 is also improved. Specifically, as shown in fig. 5, the circumferential side wall of the connection sleeve 33 is provided with a locking hole 331 together with the inside thereof. At this time, the hand-held lever 50 may include an insertion portion 51 that can be inserted into the connection sleeve 33, and a circumferential side wall of the insertion portion 51 is provided with a radially extending sliding groove (not shown), in which a locking post 52 and a second elastic member (not shown) are provided, one end of the locking post 52 extends out of the insertion portion 51, and the other end of the locking post 52 is held in the sliding groove by the second elastic member, which may be a spring provided in the sliding groove, for example.

Thus, in the initial state, one end of the locking post 52 is located outside the insertion portion 51, and the second elastic member is in a natural extension state, when the insertion portion 51 needs to be inserted into the connecting sleeve 33, the locking post 52 is pressed toward the inside of the sliding groove until the locking post 52 is completely hidden in the sliding groove, and in this process, the second elastic member is compressed to pre-store an elastic force, and then the insertion portion 51 can be inserted into the connecting sleeve 33. When the insertion portion 51 is inserted into the connection sleeve 33, the hand-held lever 50 is properly rotated to align the locking post 52 with the locking hole 331 of the connection sleeve 33, and then the second elastic member releases the pre-stored elastic force to force the locking post 52 to extend out of the sliding groove, and the locking post 52 can extend into the locking hole 331, so that the connection sleeve 33 and the hand-held lever 50 are reliably connected, and in this state, the connection sleeve 33 and the screw 32 are inevitably rotated when the hand-held lever 50 is rotated.

Of course, in actual implementation, if the hand lever 50 is composed of a plurality of bars, two adjacent bars may be connected to each other by the same connection method as the connection sleeve 33 and the insertion portion 51.

On the other hand, some embodiments of the present application also provide a ground wire erecting device for assisting an operator in completing the erecting of the ground wire 200, specifically, as shown in fig. 6, the ground wire erecting device includes the ground wire 200, the ground wire bracket 300, and the ground wire clip 100 as described in the above embodiments.

Wherein, the ground wire bracket 300 includes two columns 301 and a cross-pillar 302 disposed between the two columns 301, the two cross-pillars 302 are disposed at intervals in a vertical direction, and the ground wire 200 is wound on the two cross-pillars 302 and can be connected to the second vertical portion 13 of the bending member 10 constituting the ground wire clip 100.

It will be appreciated that in the prior art, the ground wire 200 is typically simply wound around a vertical ground stake during erection of the ground wire 200, which is inconvenient for collection of the ground wire 200. Therefore, the present application can realize the following and following placement of the ground wire 200 and facilitate the better collection of the ground wire 200 by adopting the ground wire holder 300 having a substantially square shape and winding the ground wire 200 around the two cross posts 302 of the ground wire holder 300.

The above is only a preferred embodiment of the present application, and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
