Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanying figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will recognize without departing from the spirit and scope of the present invention.
Referring to fig. 2 to 5, an embodiment of the present application provides a ground wire clamping device 10, including: a first drive assembly 110, a second drive assembly 120, and a clamping mechanism 130 coupled to the second drive assembly 120. The first transmission assembly 110 is movable relative to the second transmission assembly 120 such that the first transmission assembly 110 has a first state and a second state. When the first transmission assembly 110 is in the first state, the first transmission assembly 110 is engaged with the second transmission assembly 120, and the first transmission assembly 110 is used for driving the second transmission assembly 120 to rotate so as to switch the clamping mechanism 130 between the clamping state and the loosening state. When the first transmission assembly 110 is in the second state, the first transmission assembly 110 is disengaged from the second transmission assembly 120.
In the above-mentioned grounding wire clamping device 10, when the first transmission assembly 110 is in the first state, the first transmission assembly 110 is engaged with the second transmission assembly 120, since the first transmission assembly 110 is used for driving the second transmission assembly 120 to rotate so as to switch the clamping mechanism 130 between the clamping state and the unclamping state, when the clamping of the conducting wire 20 is required, the first transmission assembly 110 is in the first state, and at this time, the first transmission assembly 110 is rotated along the set rotation direction so as to rotate the second transmission assembly so as to enable the clamping mechanism 130 to clamp the conducting wire 20. After the clamping mechanism 130 clamps the wire 20, an operator can make the first transmission assembly 110 be in the second state, and because the first transmission assembly 110 is in the second state, the first transmission assembly 110 is separated from the second transmission assembly 120, at this time, the first transmission assembly 110 is rotated along any rotation direction, and the second transmission assembly 120 does not rotate, so that the second transmission assembly 120 can be effectively prevented from rotating by mistake, and then the clamping mechanism 130 is always in the clamping state. When the lead 20 needs to be taken out of the clamping mechanism 130, the first transmission assembly 110 can be in the first state again, and at the moment, the second transmission assembly 120 can be rotated reversely by rotating the first transmission assembly 110 away from the set rotation direction, so that the clamping mechanism 130 can be in a loosening state, and the lead 20 can be taken out.
With reference to fig. 2 to 5, in an embodiment based on the above embodiments, the ground wire clamping device 10 further includes a base 140. The base 140 is provided with a receiving cavity 141. The first transmission assembly 110 includes a first bevel gear 111 and a transmission shaft 112. The second transmission assembly 120 includes a second bevel gear 121. The first bevel gear 111 and the second bevel gear 121 are both disposed in the accommodating cavity 141. The transmission shaft 112 is slidably inserted through the base 140 and connected to the first bevel gear 111. The transmission shaft 112 can drive the first bevel gear 111 to move relative to the base 140 along the axial direction of the transmission shaft 112 so as to switch the first bevel gear 111 between the first state and the second state. As shown in fig. 4, when the first bevel gear 111 is in the first state, the first bevel gear 111 meshes with the second bevel gear 121. As shown in fig. 5, when the first bevel gear 111 is in the second state, the first bevel gear 111 is separated from the second bevel gear 121.
In this embodiment, the first bevel gear 111 is sleeved on the transmission shaft 112 and is fixedly connected to the transmission shaft 112, so that the rotation of the transmission shaft 112 can drive the rotation of the first bevel gear 111, and the movement of the transmission shaft 112 relative to the sliding seat can drive the movement of the first bevel gear 111 relative to the sliding seat.
Specifically, when the first bevel gear 111 is in the first state, the first bevel gear 111 is meshed with the second bevel gear 121, and at this time, when the first bevel gear 111 rotates clockwise, the second bevel gear 121 also rotates clockwise, and when the second bevel gear 121 is set to rotate clockwise, the clamping mechanism 130 is driven to be in the clamping state. When the second bevel gear 121 rotates counterclockwise, the second bevel gear 121 also rotates counterclockwise, and the clamping mechanism 130 is driven to be in the unclamped state when the second bevel gear 121 is set to rotate counterclockwise. Therefore, when it is desired to clamp the wire 20, the first bevel gear 111 may be rotated clockwise to cause the clamping mechanism 130 to clamp the wire 20. In order to prevent the clamping mechanism 130 from being switched from the clamping state to the unclamping state due to an accidental operation, after the clamping mechanism 130 clamps the wire 20, the transmission shaft 112 is moved to make the first bevel gear 111 in the second state, and at this time, the first bevel gear 111 is separated from the second bevel gear 121, so that the rotation of the second bevel gear 121 caused by the erroneous rotation of the first bevel gear 111 can be effectively avoided, and the clamping mechanism 130 is always in the clamping state. When the conducting wire 20 needs to be taken out of the clamping mechanism 130, the transmission shaft 112 can be moved to make the first bevel gear 111 in the first state again, and at this time, the first bevel gear 111 rotates counterclockwise, and the second bevel gear 121 also rotates counterclockwise to drive the clamping mechanism 130 to be in the unclamped state, so that the conducting wire 20 can be taken out more easily.
Optionally, in other embodiments, the first transmission assembly 110 includes a transmission shaft 112 and an external gear. The second transmission assembly 120 includes an internal gear. The outer gear and the inner gear are located in the receiving cavity 141 of the base 140. The transmission shaft 112 is slidably inserted through the base 140 and connected to the external gear. In this way, the transmission shaft 112 can drive the external gear to move relative to the base 140 to switch the external gear between the first state and the second state. When the external gear is in the first state, the external gear is disposed within and meshes with the internal gear. When the outer gear is in the second state, the outer gear is separated from the inner gear.
In order to ensure that the second transmission assembly 120 rotates to switch the clamping mechanism 130 between the clamping state and the unclamping state, referring to fig. 3 to 6, on the basis of the above embodiment, in an embodiment, the clamping mechanism 130 includes a clamping jaw assembly 131, a clamping base 132 and a rotating shaft 133. The clamping base 132 is connected with the base 140, the clamping jaw assembly 131 is rotatably mounted on the clamping base 132 through a rotating shaft 133, and the rotating shaft 133 is parallel to the transmission shaft 112. The second transmission assembly 120 further includes a sleeve 122 and a lead screw 123. The sleeve 122 is rotatably disposed through the base 140 and connected to the second bevel gear 121. The inner wall of the sleeve 122 is provided with threads (not shown). The screw 123 is disposed in the sleeve 122 and is in threaded engagement with the sleeve 122. One end of the screw 123 far away from the second bevel gear 121 is rotatably connected with the clamping jaw assembly 131. Thus, when the sleeve 122 rotates, the screw 123 moves along the axial direction thereof, and the jaw assembly 131 rotates on the holder 132 around the rotating shaft 133 and cooperates with the holder 132 to clamp or unclamp the wire 20.
In the present embodiment, the second bevel gear 121 is fixedly connected to the end of the sleeve 122, so when the second bevel gear 121 rotates, the sleeve 122 rotates synchronously with the second bevel gear 121.
Specifically, it is set that when the sleeve 122 rotates in the clockwise direction, the lead screw 123 moves in the axial direction thereof in a direction approaching the second bevel gear 121, and at this time, the jaw assembly 131 rotates to clamp the wire 20. It is set that when the sleeve 122 rotates in the counterclockwise direction, the screw 123 moves in the axial direction thereof in a direction away from the second bevel gear 121, and at this time, the jaw assembly 131 rotates to release the wire 20.
Further, as shown in fig. 1-3 and 6-8, in one embodiment, the jaw assembly 131 includes a first hook 1311 and a second hook 1312. The clamping seat 132 is provided with a notch 1321. The first hook 1311 and the second hook 1312 are respectively rotatably mounted on the clamping seat 132 through a rotating shaft 133 and located at two sides of the gap 1321. The first hook 1311 and the second hook 1312 can form a clamping area for clamping the wire 20 by enclosing with the notch 1321. As shown in fig. 8, when the first hook 1311 and the second hook 1312 rotate to approach the notch 1321, the first hook 1311, the second hook 1312 and the sidewall of the notch 1321 surround to form a clamping area, and the clamping mechanism 130 is in a clamping state. As shown in fig. 6, when the first hook 1311 and the second hook 1312 rotate to get away from the notch 1321, the clamping mechanism 130 is in an unclamped state.
To ensure that the screw 123 can simultaneously rotate the first hook 1311 and the second hook 1312 when moving along the axial direction thereof, further, as shown in fig. 1, 3, and 6 to 8, in an embodiment, the ground wire clamping device 10 further includes a push rod 150. The push rod 150 is in a "Y" shape. The first end of the push rod 150 is rotatably connected to the first hook 1311, the second end of the push rod 150 is rotatably connected to the second hook 1312, and the third end of the push rod 150 is connected to the screw rod 123. As shown in fig. 4 to fig. 8, when the push rod 150 moves along with the lead screw 123 toward the second bevel gear 121, the first hook 1311 rotates counterclockwise to approach the notch 1321, the second hook 1312 rotates clockwise to approach the notch 1321, and the wire 20 located in the notch 1321 abuts between the sidewall of the notch 1321, the first hook 1311 and the second hook 1312. When the clamping mechanism 130 needs to be switched from the clamping state to the unclamping state, when the push rod 150 moves along with the screw 123 in a direction away from the second bevel gear 121, the first hook 1311 rotates clockwise to be away from the notch 1321, and the second hook 1312 rotates counterclockwise to be away from the notch 1321, so that the wire 20 in the notch 1321 is not pressed by the first hook 1311 and the second hook 1312, and the operator can easily remove the wire 20 from the notch 1321.
In order to improve the applicability of the grounding wire clamping device 10 and improve the stability of clamping the wire 20, referring to fig. 1 and 3, in an embodiment, the clamping seat 132 includes a first panel 1322, a second panel 1323, and a connector (not shown). Notches 1321 are provided in both the first panel 1322 and the second panel 1323. The first and second panels 1322, 1323 are disposed opposite and spaced apart along the axial direction of the drive shaft 112. The connector is connected between the first panel 1322 and the second panel 1323. The space between the first panel 1322 and the second panel 1323 forms a receiving chamber 1324. The accommodating cavity 1324 is provided with an elastic clamping member 160, and the elastic clamping member 160 is used for clamping the lead 20 in the gap 1321.
Further, the clamping jaw assembly 131 may be rotatably disposed on a side of the first panel 1322 and/or the second panel 1323 facing away from the accommodating chamber 1324. Thus, the interference between the elastic clamping member 160 and the clamping jaw assembly 131 during operation can be effectively avoided.
Specifically, in the present embodiment, referring to fig. 6 to 8, the elastic clamping member 160 includes a clamping arm 161, a restoring torsion spring 162, a positioning post 163 and a limiting post 164. The clamping arm 161 is an arc-shaped structure, and one end of the clamping arm 161 is rotatably connected to the first panel 1322 and the second panel 1323. The positioning posts 163 and the limiting posts 164 are connected to the first panel 1322 and/or the second panel 1323. The positioning post 163 is sleeved with the reset torsion spring 162, and one end of the reset torsion spring 162 abuts against the limiting post 164, and the other end of the reset torsion spring 162 abuts against the clamping arm 161. Thus, when the elastic clamping member 160 is used to clamp the wire 20, the gap 1321 is aligned with the wire 20 and the clamping seat 132 is moved toward the wire 20, so that the wire 20 is pressed between the conductive clipping arms 161 and the wall surface of the gap 1321.
It should be noted that "the positioning post 163 and the limiting post 164 are both connected to the first panel 1322 and/or the second panel 1323" includes that the positioning post 163 and the limiting post 164 are both connected to the first panel 1322, or the positioning post 163 and the limiting post 164 are both connected to the second panel 1323, or the positioning post 163 is both connected to the first panel 1322 and the second panel 1323, and the limiting post 164 is both connected to the first panel 1322 and the second panel 1323.
In order to further improve the stability of the clamping, specifically, in the present embodiment, the elastic clamping member 160 is provided with two. And the two elastic clamping members 160 are respectively located at two sides of the notch 1321 and are symmetrically arranged.
Specifically, the two clamping arms 161 are respectively located at two sides of the notch 1321, and the conductive clamping arm 161 can move towards a direction close to or away from the notch 1321 under the action of the reset torsion spring 162, so that the clamping range in the notch 1321 can be adjusted, the notch 1321 can clamp the wires 20 with different diameters, and the applicability of the ground wire clamping device 10 is improved. When the diameter of the wire 20 is small, the guide can be effectively prevented from shaking in the gap 1321, so that the stability of the ground wire clamping device 10 for clamping the wire 20 is enhanced.
Referring to fig. 3 to 5, in order to keep the second bevel gear 121 and the sleeve 122 stable during the rotation process, in an embodiment based on the above embodiment, the ground wire clamping device 10 further includes a supporting shaft 170. The support shaft 170 is disposed in the receiving cavity 141. One end of the supporting shaft 170 is fixedly connected to the base 140, the other end of the supporting shaft 170 is inserted into the second bevel gear 121, and the second bevel gear 121 can rotate relative to the supporting shaft 170. In this manner, the end of the second bevel gear 121 remote from the sleeve 122 may be supported by the support shaft 170, and the end of the sleeve 122 remote from the second bevel gear 121 may be supported by the base 140.
In one embodiment, to avoid the second bevel gear 121 and the sleeve 122 from moving in the axial direction of the sleeve 122 during rotation. Referring to fig. 3 to 5, the supporting shaft 170 is provided with a first limiting protrusion 181, and the sleeve 122 is provided with a second limiting protrusion 182. The first limit boss 181 abuts against the first bevel gear 111, and the second limit boss 182 abuts against the base 140.
Referring to fig. 1 to 5, in order to facilitate the operator to operate the transmission shaft 112, the ground wire clamping device 10 further includes an operating rod 190. The transmission shaft 112 passes through the base 140 and is fixedly connected with the operation rod 190. Thus, the rotation of the operating lever 190 drives the transmission shaft 112 to rotate.
It should be noted that the operating rod 190 in this embodiment is a rod held by an operator, and therefore, in order to ensure the personal safety of the operator, the operating rod 190 is an insulating rod with insulating performance.
It should be noted that the height of the operating lever 190 can be set according to the position on the wire 20 for hanging the grounding lead 30.
Optionally, in an embodiment, the operating lever 190 is a telescopic lever.

In the present application, it is assumed that the notch 1321 of the holder 132 is oriented in a first direction, and the axial direction of the transmission shaft 112 and/or the operating rod 190 is oriented in a second direction. Since the first direction intersects the second direction, in the present application, for the wire 20 that is vertically arranged in a place such as a substation, when such a wire 20 needs to be grounded, an operator may stand on the ground to hold the operating rod 190, so that the axial direction of the operating rod 190 extends in the vertical direction, and thus, the notch 1321 can directly face the wire 20, and at this time, the operating rod 190 is moved in a direction that is close to the wire 20, so that the wire 20 can be clamped into the notch 1321, so as to subsequently clamp the wire 20.
Specifically, in the present embodiment, the first direction is perpendicular to the second direction.
Specifically, when the present ground wire clamping device 10 is used for the lead wire 20 installed on a vertical ground surface, as shown in fig. 1 and 2, the operating lever 190 should be made vertical to the ground surface, and the notch 1321 should be opened in a horizontal direction. Therefore, the difficulty of conducting the operation of the grounding lead 30 on the lead 20 can be reduced, the lifting equipment does not need to be additionally matched, and the grounding operation efficiency is improved.
