Description

Technical Field

[0001] The utility model belongs to the technical field of power line clamps, and particularly relates to a grounding wire clamp. Background Art

[0002] When overhauling high-voltage equipment or lines such as 10 kV and 35 kV in the power system, in order to ensure the safety of construction personnel, power outage maintenance is carried out on high-voltage equipment or lines. At the same time, in order to cope with the accidental risks brought by accidental power-on, grounding wire operations are further carried out on transmission lines. Usually, the grounding wire tool consists of a grounding wire and grounding wire clamps at both ends. During use, one end of the grounding wire clamp clamps the transmission line, and the other end of the grounding wire clamp clamps the grounding conductor to complete the grounding operation.

[0003] The existing grounding wire clamps are flat-mouth clamp types. For example, the clamping device disclosed in the patent document with the publication number CN114069268A is a flat-mouth clamp type. When hanging cables, the flat-mouth wire clamp needs to be lifted by an insulating rod. When hanging on the transmission line, due to the high height of the transmission line, it is difficult to adjust the opening height of the flat-mouth wire clamp, so that it is difficult to align the flat-mouth wire clamp with the transmission line, and it takes a long time to hang. Content of the Utility Model

[0004] The purpose of the utility model is to provide a grounding wire clamp to solve the problems mentioned in the above background art.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A grounding wire clamp, comprising a base plate, a conductive plate, and a hanging rod assembly; the base plate is a vertical plate-like structure, a conductive plate in the form of a copper plate is fixedly attached to the rear surface of the base plate, a grounding wire is connected to the conductive plate, a clamp seat is provided on one side of the base plate away from the conductive plate, one side of the clamp seat is a circular arc concave structure and the other side penetrates through the base plate and the conductive plate for electrical connection, an arc-shaped clamp in the form of an arc plate is rotatably fitted on the clamp seat by a rotating shaft, and bent plate-like structures extending away from the base plate are respectively provided on the upper and lower sides of the arc-shaped clamp to form a lever plate and a guiding inclined plate respectively. A torsion spring is provided on the rotating shaft, so that there is an elastic tendency for the guiding inclined plate side of the arc-shaped clamp to deflect towards the base plate. An insulating screw ring is provided on the base plate at the same height as the lever plate, a top bolt is threadedly connected inside the insulating screw ring, and a rotating ring is connected to the side of the top bolt away from the lever plate through a vertical steering device.

[0007] Furthermore, in order to achieve vertical transmission, the vertical steering device includes: a rotating seat, a transmission rod, a first universal joint, and a second universal joint. The rotating seat is made of insulating material and is fixed to the base plate with bolts. The conductive plate is provided with holes for the bolts for installing the rotating seat to penetrate. A transmission rod is rotatably fitted on the rotating seat. The axis of the transmission rod and the conductive plate form an angle of forty-five degrees. The first universal joint and the top bolt are used for transmission connection above the transmission rod, and the second universal joint and the swivel are used for transmission connection below the transmission rod.

[0008] Furthermore, in order to facilitate the rotation of the swivel at a high place, the hanging rod assembly includes: a swivel rod, a sleeve, and a hook; the swivel rod is a rod-shaped structure; a sleeve is embedded on the swivel rod, and the sleeve and the swivel rod are rotatably matched, and a hook is provided at one end of the swivel rod that can be mounted on the swivel.

[0009] Furthermore, in order to facilitate lifting the base plate at a high place and rotating the rotating rod, the hanging rod assembly also includes: a side hanging rod, which is a straight rod with a square column structure. The side hanging rod is vertically connected to the end of the rotating rod away from the hook. A side socket for inserting the side hanging rod is provided on the side of the base plate, and the longitudinal outer contour of the side socket is consistent with the longitudinal outer contour of the side hanging rod.

[0010] Furthermore, in order to make the side hanging rod insert into the side insertion hole more smoothly, the end of the side hanging rod is tapered to form a tapered head.

[0011] Furthermore, in order to ensure a more secure connection between the base plate and the side hanging rod when the side hanging rod is inserted into the side socket, the side hanging rod is provided with at least one group of elastic bumpers with elastic contraction capability, and the side wall of the side socket is provided with a recess for accommodating the elastic bumpers.

[0012] Furthermore, in order to facilitate the placement of the power transmission line during the line hanging operation, the base plate is provided with a smooth contour cutout at the same height as the guide bevel to form an inner concave position, and an embedding gap that is narrow at the top and wide at the bottom is formed between the inner concave position and the guide bevel.

[0013] Furthermore, in order to provide better anti-displacement friction after the arc-shaped clamp clamps the power transmission line, anti-slip grooves are provided on the inner concave part of the arc-shaped clamp.

[0014] Furthermore, in order to compensate for the length difference when the push bolt is fed, the push bolt includes: an inner rod and a threaded sleeve. The inner rod is a prismatic structure, one side of which is slidably embedded in the threaded sleeve, and the other side is connected to the first universal joint. A cavity is provided in the threaded sleeve for the inner rod to slide, and the threaded sleeve and the insulating screw ring are threaded together.

[0015] Furthermore, in order to improve construction safety, the rotating rod and the sleeve are both made of insulating materials.

[0016] In summary, the present invention has the following beneficial effects:

[0017] Mounting is simpler and faster: By setting up the clip seat, deflection clip, and top bolt, the rotating rod places the entire device on the transmission line, and the transmission line is clamped in the embedding gap. Then, pull down the pull rod, and the base plate, clip seat, and deflection clip move downwards as a whole. Under the guiding action of the guiding inclined piece and the concave position, the entire deflection clip deflects around the rotating shaft so that the transmission line can pass through the embedding gap. The transmission line enters between the clip seat and the arc clip from the embedding gap. Since a torsion spring is provided on the rotating shaft, there is an elastic tendency for the guiding inclined piece side of the arc clip to deflect towards the base plate, so the arc clip will clamp the transmission line tightly in the clip seat, and the anti-slip pattern provides anti-slip friction. Then, control the rotating rod to extract the side hanging rod from the base plate, and then turn the entire hanging rod assembly so that its hook is facing upwards. Then, use the rotating rod to hang the hook on the rotating ring, and use the side hanging rod as a crank. Hold the sleeve and rotate the rotating rod. The rotating rod drives the rotating ring to rotate through the hook. The rotating ring drives the inner rod of the top bolt to rotate through the guiding of the second universal joint, transmission rod, and first universal joint. Furthermore, the inner rod drives the externally embedded threaded sleeve to rotate. Also, because the threaded sleeve and the insulating screw ring are in threaded fit, when the threaded sleeve rotates, it will translate relative to the insulating screw ring. By controlling the rotation direction of the rotating rod, control the threaded sleeve to move towards the plate side until the plate is rotated and pressed tightly by the threaded sleeve, thereby making the deflection clip and the clip seat clamp more tightly, and also preventing the wire clip from falling off the transmission line, adding an additional safety guarantee.

[0018] In summary, when this application is used, there is no need to align the opening of the wire clip. Just place the embedding gap above the transmission line and then pull down the rotating rod. The transmission line will automatically buckle in and be clamped under the action of the torsion spring. Compared with the comparative technology, the mounting is simpler and faster.

DETAILED DESCRIPTION

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] Example:

[0028] See also Figures 1-6 , this utility model provides a technical solution:

[0029] A grounding wire clamp, a base plate 1, a conductive plate 2, and a hanging rod assembly 9; the base plate 1 is a vertical plate-like structure, a conductive plate 2 with a copper plate structure is attached and fixed to the rear surface of the base plate 1, and a grounding wire 3 is connected to the conductive plate 2. A clamp seat 4 is provided on the side of the base plate 1 away from the conductive plate 2, one side of the clamp seat 4 is a circular arc concave structure, and the other side penetrates the base plate 1 and is electrically connected to the conductive plate 2, and the clamp seat 4 adopts a rotating shaft 10 to rotate with an arc-shaped arc clamp 51, and the upper and lower sides of the arc clamp 51 are respectively provided with a bent plate structure facing away from the base plate 1. A lever 52 and a guide bevel 53 are formed respectively, and a torsion spring is provided on the rotating shaft 10, so that the guide bevel 53 side of the arc clamp 51 has an elastic tendency to deflect toward the base plate 1. The base plate 1 is provided with an insulating screw ring 12 at the same height as the lever 52. The insulating screw ring 12 is connected to a push bolt 6 through the internal thread. The side of the push bolt 6 away from the lever 52 is connected to a swivel 8 through a vertical deflector 7.

[0030] The vertical steering device 7 includes: a rotating seat 71, a transmission rod 72, a first universal joint 73, and a second universal joint 74. The rotating seat 71 is made of insulating material and is fixed to the base plate 1 with bolts. The conductive plate 2 is provided with holes for the bolts for installing the rotating seat 71 to penetrate. A transmission rod 72 is rotatably fitted on the rotating seat 71. The axis of the transmission rod 72 and the conductive plate 2 form an angle of forty-five degrees. The first universal joint 73 and the top bolt 6 are used for transmission connection above the transmission rod 72, and the second universal joint 74 and the swivel 8 are used for transmission connection below the transmission rod 72.

[0031] The hanging rod assembly 9 includes: a rotating rod 91, a sleeve 92, and a hook 93; the rotating rod 91 is a rod-shaped structure (for the convenience of the view in the illustration, the length of the rotating rod 91 is somewhat omitted, and the rotating rod 91 in the illustration is not in the actual proportion); a sleeve 92 is externally embedded on the rotating rod 91, and the sleeve 92 and the rotating rod 91 are in rotational fit, and a hook 93 that can be hung on the rotating ring 8 is provided at one end of the rotating rod 91.

[0032] The hanging rod assembly 9 further includes: a side hanging rod 94, the side hanging rod 94 is a straight rod with a square column structure, the side hanging rod 94 is vertically connected to one end of the rotating rod 91 away from the hook 93, and a side insertion hole 11 for inserting the side hanging rod 94 is provided on the side surface of the base plate 1, and the longitudinal cross-sectional outer contour of the side insertion hole 11 is the same as the longitudinal cross-sectional outer contour of the side hanging rod 94.

[0033] The end of the side hanging rod 94 is tapered to form a tapered head 95.

[0034] At least one set of elastic beads 96 with elastic contraction ability is provided on the side hanging rod 94, and a concave pit for accommodating the elastic beads 96 is provided on the side wall of the side insertion hole 11.

[0035] The base plate 1 is provided with a smoothly contoured cut at the same height as the guiding inclined piece 53 to form an inner concave position 13, and an embedding gap 55 that is narrow at the top and wide at the bottom is formed between the inner concave position 13 and the guiding inclined piece 53.

[0036] Anti-slip lines 54 are provided at the inner concave part of the arc-shaped clamp 51.

[0037] The top bolt 6 includes: an inner rod 61 and a threaded sleeve 62. The inner rod 61 is a prismatic structure, one side of which is slidably embedded in the threaded sleeve 62, and the other side is connected to the first universal joint 73. A cavity for the inner rod 61 to slide is provided in the threaded sleeve 62, and the threaded sleeve 62 is in threaded fit with the insulating screw ring 12.

[0038] The rotating rod 91 and the sleeve 92 are both made of insulating materials.

[0039] During use, turn over the hanging rod assembly 9, place the side hanging rod 94 of the hanging rod assembly 9 upwards, and then insert the side hanging rod 94 into the base plate 1;

[0040] Again, such as Figure 3As shown, the whole device is placed on the transmission line 14 by using the rotating rod 91, and the transmission line 14 is clamped in the embedding gap 55. Then, the pull rod 91 is pulled down, and the base plate 1, the clamping seat 4, and the deflection clamp 5 move downwards as a whole. Under the guiding action of the guiding inclined piece 53 and the concave position 13, the whole deflection clamp 5 deflects around the rotating shaft 10 so that the transmission line 14 can pass through the embedding gap 55. The transmission line 14 enters between the clamping seat 4 and the arc-shaped clamp 51 from the embedding gap 55. Since a torsion spring is provided on the rotating shaft 10, the guiding inclined piece 53 side of the arc-shaped clamp 51 has an elastic tendency to deflect towards the base plate 1, so the arc-shaped clamp 51 will bite the transmission line 14 tightly in the clamping seat 4, and the anti-slip pattern 54 provides anti-slip friction force;

[0041] Then, control the rotating rod to draw out the side hanging rod 94 from the base plate 1, and then turn the direction of the whole hanging rod assembly 9 so that its hook 93 is upward. Then, use the rotating rod to mount the hook 93 on the rotating ring 8. Then, use the side hanging rod 94 as a crank, and hold the sleeve 92 to rotate the rotating rod 91. The rotating rod 91 drives the rotating ring 8 to rotate through the hook 93. The rotating ring 8 drives the inner rod 61 of the top bolt 6 to rotate through the guiding of the second universal joint 74, the transmission rod 72, and the first universal joint 73. Furthermore, the inner rod 61 drives the externally embedded threaded sleeve 62 to rotate. Also, because the threaded sleeve 62 and the insulating screw ring 12 are in threaded fit, when the threaded sleeve 62 rotates, it will translate relative to the insulating screw ring 12. By controlling the rotating direction of the rotating rod 91, control the threaded sleeve 62 to move towards the plate 52 side until the plate 52 is rotationally pressed by the threaded sleeve 62, thereby making the clamping of the deflection clamp 5 and the clamping seat 4 more tight, and also preventing the wire clamp from falling off the transmission line 14, adding an additional safety guarantee;

[0042] Because one side of the clamping seat 4 penetrates through the base plate 19 (the clamping seat 4 is made of conductive material) and is electrically connected to the conductive plate 2, the transmission line is electrically connected through the clamping seat 4 and the conductive plate 2. The conductive plate 2 is electrically connected to the grounding wire 3, and the other end of the grounding wire 3 is grounded, thus completing the grounding operation of the transmission line 14.

[0043] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
