[0026] like Figure 1 and Figure 2As shown, the grounding device of this embodiment includes: a support sleeve rod 10, a clamping structure 20, a transmission structure 30, a driving member 40, a sensor and a controller. The clamping structure 20 is arranged at the top of the support sleeve rod 10, and the clamping structure 20 includes a clamping hook 21 and a clamping base 22. A clamping space 23 is formed between the top of the clamping hook 21 and the clamping base 22. The clamping base 22 is movably arranged on the clamping hook 21 and can be close to or away from the top of the clamping hook 21 to change the size of the clamping space 23. The transmission structure 30 is movably arranged in the support sleeve rod 10, and the transmission structure 30 is connected to the clamping base 22. The driving member 40 is arranged on the support sleeve rod 10, and the output shaft of the driving member 40 is driven and matched with the transmission structure 30 to drive the clamping base 22 to move through the transmission structure 30. The sensor is arranged on the output shaft of the driving member 40. The controller is connected to the sensor signal and controls the operation of the driving member 40 according to the detection signal of the sensor.

[0027] The technical solution of this embodiment is applied, and the grounding device includes a support sleeve rod 10, a clamping structure 20 arranged at the top of the support sleeve rod 10, a transmission structure 30 movably arranged in the support sleeve rod 10, a driving member 40 arranged on the support sleeve rod 10, a sensor arranged on the output shaft of the driving member 40, and a controller connected to the sensor signal. The clamping structure 20 includes a clamping hook 21 and a clamping base 22, and a clamping space is formed between the top of the clamping hook 21 and the clamping base 22. The clamping base 22 is movably arranged on the clamping hook 21 so that the clamping base 22 can be close to or away from the top of the clamping hook 21 to change the size of the clamping space 23. The transmission structure 30 is connected to the clamping base 22. The output shaft of the driving member 40 is driven and matched with the transmission structure 30 to drive the clamping base 22 to move through the transmission structure 30. The controller controls the operation of the driving member 40 according to the detection signal of the sensor. Through the above-mentioned settings, the support sleeve rod 10 can support the clamping structure 20, the transmission structure 30 and the driving member 40. The driving member 40 can drive the transmission structure 30 to move, and the movement of the transmission structure 30 can drive the clamping base 22 to move, and the clamping base 22 can move toward or away from the top of the clamping hook 21 to change the size of the clamping space 23. The sensor can detect the driving member 40 to determine whether the clamping structure 20 clamps the wire, and then the controller can control the operation of the driving member 40. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that it is impossible to determine when to stop the drive motor.

[0028] The clamping hook 21 comprises a horizontal plate, a semi-circular plate and a connecting vertical plate connected between the horizontal plate and the semi-circular plate, wherein the horizontal plate is connected to the supporting sleeve rod. The middle part of the semi-circular plate is protruded toward a side away from the horizontal plate.

[0029] The clamping base 22 includes a clamping bar, and the middle part of the clamping bar on one side facing the semi-annular plate is concavely arranged in a direction away from the semi-annular plate to form a clamping arc surface.

[0030] The wire is clamped between the middle portion of the semi-annular plate and the clamping arc surface.

[0031] The radius of the side of the semi-annular plate in contact with the wire is smaller than the radius of the clamping arc surface, so that the clamping hook can be hung on the guide more stably and the clamping arc surface can clamp the wire more effectively.

[0032] like Figure 2 As shown, in this embodiment, the output shaft of the driving member 40 is rotatably arranged, and the sensor includes a torque sensor, which is connected between the output shaft of the driving member 40 and the transmission structure 30. The torque sensor can detect the torque of the output shaft of the driving member 40 and transmit the detection signal to the controller. In the process of the clamping structure 20 clamping the wire, the detection value of the torque sensor is stable within a range, which makes it easy for the controller to judge whether the clamping structure 20 has clamped the wire, that is, to realize automatic judgment of whether the clamping structure 20 has clamped the wire. After the clamping structure 20 is clamped, the driving member can stop running.

[0033] The grounding device also includes a buzzer, which is connected to the controller. When the controller determines that the clamping structure 20 has clamped the wire, the controller controls the buzzer to alarm, prompting the operator to press the start-stop button to make the controller control the drive component to stop running.

[0034] When the grounding device is in use, pressing the start / stop button enables the drive to operate.

[0035] In other embodiments, the sensor further includes a strain gauge disposed on the output shaft of the driving member, and the controller calculates the torque of the output shaft of the driving member based on data collected by the strain gauge.

[0037] like Figure 2 and Figure 4As shown, in this embodiment, the transmission structure 30 further includes a second transmission rod 32 disposed in the support sleeve rod 10, the torque sensor is connected between the first end of the second transmission rod 32 and the output shaft of the driving member 40, and the second end of the second transmission rod 32 is threadedly engaged with the first end of the first transmission rod 31. The output shaft of the driving member 40 can drive the second transmission rod 32 to rotate, and then the second transmission rod 32 can drive the first transmission rod 31 to move in the support sleeve rod 10.

[0038] like Figure 2 and Figure 4 As shown, in this embodiment, the transmission structure 30 further includes a baffle 33 disposed in the middle of the first transmission rod 31, an inner boss 11 is disposed in the support sleeve rod 10, and the grounding device further includes an elastic member 50, which is sleeved on the outer periphery of the first transmission rod 31 and located between the baffle 33 and the inner boss 11. When the first transmission rod 31 moves, it can squeeze the elastic member 50, and since the compression amount of the elastic member 50 is certain, the moving distance of the first transmission rod 31 can be controlled, so as to prevent the first transmission rod 31 from driving the clamping base 22 to move excessively, thereby preventing the clamping base 22 and the clamping hook 21 from clamping the wire.

[0039] It should be noted that the elastic member 50 includes a spring.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, the clamping structure 20 further includes a guide structure 24 disposed between the clamping hook 21 and the clamping base 22 to guide the movement of the clamping base 22. The guide structure 24 can guide the movement of the clamping base 22 so that the clamping base 22 moves more smoothly.

The first connecting sleeve rod 12 can connect the handle 60 and the clamping hook 21. The side of the first connecting sleeve rod 12 facing the baffle 33 can squeeze the elastic member 50 together with the baffle.

[0046] like Figure 2 and Figure 3 As shown, in this embodiment, the support sleeve rod 10 further includes a second connection sleeve rod 13, and a connection through hole 131 is provided on the second connection sleeve rod 13. The second end of the first connection sleeve rod 12 is connected to an end of the connection through hole 131 close to the clamping hook 21, and the handle 60 is connected to an end of the connection through hole 131 away from the clamping hook 21. The provision of the connection through hole 131 facilitates the connection between the first connection sleeve rod 12 and the clamping hook 21.

[0047] like Figure 2 and Figure 3 As shown, in this embodiment, the support sleeve rod 10 further includes a third connection sleeve rod 14, and the third connection sleeve rod 14 is provided with an avoidance through hole 141. The first end of the third connection sleeve rod 14 is connected to the first connection sleeve rod 12, and the second end of the third connection sleeve rod 14 is connected to the clamping hook 21. The middle part of the first transmission rod 31 is penetrated in the avoidance through hole 141. The third connection sleeve rod 14 can connect the first connection sleeve rod 12 and the clamping hook 21. The avoidance through hole 141 allows the first transmission rod 31 to pass through the third connection sleeve rod 14, and then the first transmission rod 31 can be connected to the clamping base 22.

[0048] The support sleeve 10 also includes a fourth connecting sleeve, in which the first transmission rod 31 and the second transmission rod 32 are arranged. The end of the connecting hole 131 away from the clamping hook 21 is connected to the fourth connecting sleeve, and the end of the fourth connecting sleeve away from the second connecting sleeve is connected to the handle 60.

[0049] The supporting sleeve rod 10 further includes a fifth connecting sleeve rod disposed between the fourth connecting sleeve rod and the handle, and the driving member 40 is disposed in the fifth connecting sleeve rod.

[0052] The grounding device of this embodiment is an electrically tightened and loosened 10V grounding wire device.

[0053] The grounding device of this embodiment has the following advantages:

[0054] (1) It can speed up the installation and removal of grounding wires, making construction faster and more convenient, saving manpower and time costs, and thus effectively solving the problem of time-consuming and labor-intensive installation and removal of traditional grounding wires.

[0055] (2) A tightening reminder setting connected to the controller signal is provided. The tightening reminder setting can be a buzzer, which can ensure that the grounding wire is installed firmly, effectively solving the problem that the quality of traditional grounding wire installation is difficult to judge, and eliminating safety hazards.

[0056] (3) An extreme state prompt setting is provided, which can be an indicator light, and the indicator light is an LED light, so as to avoid overheating when the driving part cannot rotate, thereby extending the service life of the grounding device and improving the economy.

[0057] (4) Simple operation and low cost. The main cost lies in the drive components and their control devices, which is conducive to large-scale promotion.

[0058] (5) Combining manual judgment with machine judgment, first determine whether the grounding wire is securely installed by monitoring the torque of the driving component, and then the operator determines whether the grounding device is securely installed again by observing and shaking the grounding device.

[0059] (6) Using a drive to provide power for the installation and removal of the grounding wire not only retains the advantage of not needing to borrow power from the wire, but also saves the physical strength of the operator, improves work efficiency, and reduces the installation and removal time of the grounding device.

[0060] (7) A simple tension key is used to control the driving member, and the start and stop control of the driving member is realized through a start and stop button, and an indicator light is installed on the handle 60 to show that the grounding device has been firmly installed.

[0061] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0062] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0063] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
