Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the invention, whereby the invention is not limited to the specific embodiments disclosed below.
Referring to fig. 2 to 5, an embodiment of the present application provides a ground wire clamping device 10, including: the first transmission assembly 110, the second transmission assembly 120, and a clamping mechanism 130 coupled to the second transmission 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 unclamping state. When the first transmission assembly 110 is in the second state, the first transmission assembly 110 is decoupled from the second transmission assembly 120.
In the above-described ground 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, and since the first transmission assembly 110 is used to drive 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 wire 20 needs to be clamped, 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 wire 20. After the clamping mechanism 130 clamps the wire 20, an operator can make the first transmission assembly 110 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, and at this time, the first transmission assembly 110 is rotated along any direction, and the second transmission assembly 120 is not rotated, so that the error rotation of the second transmission assembly 120 can be effectively avoided, and then the clamping mechanism 130 is always in the clamped state. When the wire 20 needs to be removed from the clamping mechanism 130, the first transmission assembly 110 can be again placed in the first state, and at this time, rotating the first transmission assembly 110 away from the set steering can reverse the rotation of the second transmission assembly 120, so that the clamping mechanism 130 can be placed in the released state, and the wire 20 can be removed.
With continued reference to fig. 2 to 5, in one embodiment, the ground wire clamping device 10 further includes a base 140. The base 140 is provided with a receiving chamber 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 disposed in the accommodating chamber 141. The drive shaft 112 is slidably disposed through the base 140 and coupled to the first bevel gear 111. The transmission shaft 112 can drive the first bevel gear 111 to move along the axial direction of the transmission shaft 112 relative to the base 140 so as to switch the first bevel gear 111 between a first state and a second state. As shown in fig. 4, when the first bevel gear 111 is in the first state, the first bevel gear 111 is meshed 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 with the transmission shaft 112, so that the rotation of the transmission shaft 112 can drive the first bevel gear 111 to rotate, and the movement of the transmission shaft 112 relative to the slide can drive the first bevel gear 111 to move relative to the slide.
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, at this time, when the first bevel gear 111 rotates clockwise, the second bevel gear 121 also rotates clockwise, and the second bevel gear 121 is set to rotate clockwise to drive the clamping mechanism 130 to be in the clamped 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 a released state when the second bevel gear 121 rotates counterclockwise. Thus, 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 accidental operation, after the clamping mechanism 130 clamps the wire 20, the transmission shaft 112 is moved to enable the first bevel gear 111 to be in the second state, and at this time, the first bevel gear 111 is separated from the second bevel gear 121, so that the second bevel gear 121 can be effectively prevented from rotating due to incorrect rotation of the first bevel gear 111, and the clamping mechanism 130 is always in the clamping state. When the wire 20 needs to be removed from the clamping mechanism 130, the transmission shaft 112 is moved to bring the first bevel gear 111 into the first state again, and at this time, the first bevel gear 111 is rotated counterclockwise, and the second bevel gear 121 is also rotated counterclockwise to drive the clamping mechanism 130 into the released state, so that the wire 20 can be removed more easily.
Alternatively, in other embodiments, the first drive assembly 110 includes a drive shaft 112 and an external gear. The second transmission assembly 120 includes an internal gear. The outer gear and the inner gear are both positioned in the receiving cavity 141 of the base 140. The drive shaft 112 is slidably disposed through the base 140 and coupled to the external gear. Thus, the transmission shaft 112 can also 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 meshed with the internal gear. When the external gear is in the second state, the external gear is separated from the internal 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, in the above embodiment, the clamping mechanism 130 includes a clamping jaw assembly 131, a clamping seat 132 and a rotating shaft 133. The clamping seat 132 is connected with the base 140, the clamping jaw assembly 131 is rotatably mounted on the clamping seat 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 screw 123. The sleeve 122 is rotatably installed on 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. The end of the screw 123 remote from the second bevel gear 121 is rotatably connected to the jaw assembly 131. Thus, when the sleeve 122 is rotated, the screw 123 moves in the axial direction, and the jaw assembly 131 rotates on the clamping seat 132 around the rotating shaft 133 and cooperates with the clamping seat 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 that 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 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 loosen 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 rotatably mounted on the clamping seat 132 through a shaft 133 respectively and located at two sides of the notch 1321. The first hook 1311 and the second hook 1312 can enclose with the notch 1321 to form a clamping area for clamping the wire 20. 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 and the second hook 1312 and the side wall of the notch 1321 enclose to form a clamping area, and the clamping mechanism 130 is in a clamped state. As shown in fig. 6, when the first hook 1311 and the second hook 1312 rotate away from the notch 1321, the clamping mechanism 130 is in a released state.
In order to ensure that the screw 123 moves along the axial direction thereof and simultaneously drives the first hook 1311 and the second hook 1312 to rotate simultaneously, 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 pushrod 150 has a "Y" configuration. 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 123. Referring to fig. 4 to 8, when the push rod 150 moves along with the screw rod 123 in a direction approaching the second bevel gear 121, the first hook 1311 rotates in a counterclockwise direction to approach the notch 1321, the second hook 1312 rotates in a clockwise direction 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 is required to be switched from the clamping state to the releasing state, the push rod 150 can be moved along with the screw rod 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 an operator can easily remove the wire 20 from the notch 1321.
In order to improve the applicability of the ground wire clamping device 10 and improve the stability of clamping the conductive wire 20, please refer to fig. 1 and 3, in an embodiment, the clamping base 132 includes a first panel 1322, a second panel 1323, and a connector (not shown). The first panel 1322 and the second panel 1323 are provided with a notch 1321. The first panel 1322 and the second panel 1323 are disposed opposite to and spaced apart from each other in 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 cavity 1324. The accommodating cavity 1324 is provided with an elastic clamping member 160, and the elastic clamping member 160 is used for clamping the wire 20 located in the notch 1321.
Further, jaw assembly 131 is rotatably disposed on a side of first panel 1322 and/or second panel 1323 facing away from receiving cavity 1324. Thus, the interference with the clamping jaw assembly 131 during the operation of the elastic clamping member 160 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 return torsion spring 162, a positioning post 163, and a limiting post 164. The clamping arm 161 has an arc-shaped structure, and one end of the clamping arm 161 is rotatably connected with the first panel 1322 and the second panel 1323. The positioning posts 163 and the limit posts 164 are each connected to the first panel 1322 and/or the second panel 1323. The reset torsion spring 162 is sleeved on the positioning post 163, one end of the reset torsion spring 162 is abutted against the limiting post 164, and the other end of the reset torsion spring 162 is abutted against the clamping arm 161. Thus, when the elastic clamping member 160 is required to clamp the wire 20, the notch 1321 is aligned with the wire 20, so that the clamping seat 132 moves toward the wire 20, and the wire 20 presses between the conductive clamping arm 161 and the wall surface of the notch 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 that the positioning post 163 and the limiting post 164 are both connected to the second panel 1323, or that the positioning post 163 is simultaneously connected to the first panel 1322 and the second panel 1323, and that the limiting post 164 is simultaneously connected to the first panel 1322 and the second panel 1323.
In order to further improve the stability of the clamping, in particular, 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 symmetrically arranged.
Specifically, the two clamping arms 161 are respectively located at two sides of the notch 1321, and the conductive clamping arms 161 can move towards a direction approaching or departing 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, so that the notch 1321 can clamp 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 smaller, the guide can be effectively prevented from shaking in the notch 1321, so as to enhance the stability of clamping the wire 20 by the ground wire clamping device 10.
Referring to fig. 3 to 5, in order to keep the second bevel gear 121 and the sleeve 122 stable during rotation, in addition to the above embodiment, in one embodiment, the ground wire clamping device 10 further includes a support shaft 170. The support shaft 170 is provided in the receiving chamber 141. One end of the support shaft 170 is fixedly connected with the base 140, the other end of the support shaft 170 is inserted into the second bevel gear 121, and the second bevel gear 121 can rotate relative to the support shaft 170. As such, 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. With continued reference to fig. 3 to 5, the support shaft 170 is provided with a first limiting boss 181, and the sleeve 122 is provided with a second limiting boss 182. The first limiting boss 181 abuts against the first bevel gear 111, and the second limiting boss 182 abuts against the base 140.
Referring to fig. 1 to 5, in order to facilitate the operation of the transmission shaft 112 by an operator, the ground wire clamping device 10 further includes an operation lever 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 can drive the transmission shaft 112 to rotate.
It should be noted that, the operation rod 190 in this embodiment is a rod held by an operator, and therefore, in order to ensure personal safety of the operator, the operation rod 190 is an insulating rod having an insulating property.
The height of the operating lever 190 may be set according to the position of the wire 20 where the ground lead 30 is suspended.
Alternatively, in one embodiment, the lever 190 is a telescoping lever.
Referring to fig. 2, 4 and 5, in an embodiment, a connection portion 142 for connecting the ground lead 30 is provided on the base 140. The ground lead 30 is connected to the connection portion 142 via the copper terminal 40.
In this application, it is assumed that the notch 1321 on the clamping seat 132 is oriented in a first direction, and the axial direction of the transmission shaft 112 and/or the operating lever 190 is in a second direction. Because the first direction intersects the second direction, therefore, in this application, when the wire 20 vertically disposed in a place such as a transformer substation needs to be grounded, an operator can stand on the ground to hold the operating lever 190, so that the axial direction of the operating lever 190 extends along the vertical direction, and the notch 1321 can be directly faced to the wire 20, at this time, the operating lever 190 is moved in a direction close to the wire 20, so that the wire 20 can be clamped into the notch 1321 for subsequent clamping operation on the wire 20.
Specifically, in the present embodiment, the first direction is perpendicular to the second direction.
Specifically, when the present ground wire holding device 10 is used for the wire 20 disposed on the vertical ground, the operation lever 190 is set to be vertical to the ground and the notch 1321 is opened in the horizontal direction as shown in fig. 1 and 2. Therefore, the difficulty of carrying out the operation of the grounding lead 30 on the lead 20 can be reduced, the matching with lifting equipment is not needed, and the grounding operation efficiency is improved.
