For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0040] Reference will be made below to Figures 1-9 describe a clamping device 100 according to an embodiment of the present invention.

[0041] As Figure 1 shown, an embodiment of the first aspect of the present invention provides a clamping device 100, which includes a clamping structure 1, a locking structure 2, and a connection structure 3 for a transmission line traveling device.

[0042] The clamping structure 1 includes a clamping member mounting seat 13, a first clamping member 11 and a second clamping member 12. The first clamping member 11 is mounted on the clamping member mounting seat 13, and the first clamping member 11 can move relative to the clamping member mounting seat 13; the second clamping member 12 is mounted on the clamping member mounting seat 13, and the second clamping member 12 can move relative to the clamping member mounting seat 13. The first clamping member 11 and the second clamping member 12 can both move in a direction towards each other, and thus clamp on opposite sides of the object to be clamped. The object to be clamped here can be a power transmission line, so the first clamping member 11 and the second clamping member 12 can both move in a direction towards each other until the power transmission line is clamped.

[0043] The locking structure 2 includes a lock seat 21, a locking arm 22 and a locking member 23. The lock seat 21 is fixedly connected to the clamping member mounting seat 13, the locking member 23 is pivotally arranged on the lock seat 21, and the locking member 23 is connected to the first clamping member 11. The locking arm 22 is connected to the locking member 23, and the locking arm 22 can pull the locking member 23 to rotate in the first direction. When the locking member 23 pivots in the first direction, it can apply a pressure towards the second clamping member 12 to the first clamping member 11, thereby further clamping the power transmission line.

[0044] Specifically, one end of the locking arm 22 is hinged to the locking member 23, and the other end of the locking arm 22 is hinged to the power transmission line walking device connection structure 3, and the power transmission line walking device connection structure 3 can also be connected to the power transmission line walking device 200.

[0045] In a specific application scenario, the power transmission line walking device 200 drives the insulating net to walk on the power transmission line, and the power transmission line walking device 200 can transport the insulating net to a designated position. Specifically, four power transmission line walking devices 200 can be used to respectively pull a corner of the insulating net to walk on the power transmission line, so as to transport the insulating net to the designated location, and every two power transmission line walking devices 200 walk on the same power transmission line. Each power transmission line walking device 200 is connected to a clamping device 100 through the power transmission line walking device connection structure 3. When the four power transmission line walking devices 200 reach the designated position, the first clamping member 11 and the second clamping member 12 of each clamping device 100 move in a direction towards each other, and the clamping structure 1 clamps the power transmission line, thereby fixing the power transmission line walking device 200 and the insulating net. When an insulating net dropping accident occurs, a huge dragging force is applied to the locking arm 22 through the power transmission line walking device connection structure 3, so that the insulating net pulls the locking member 23 to rotate in the first direction through the locking arm 22. When the locking member 23 pivots in the first direction, it can apply a pressure towards the second clamping member 12 to the first clamping member 11, thereby further clamping the power transmission line.

[0046] The clamping device 100 provided by the embodiment of the present invention has the following advantages:

[0047] (1)When an insulating net dropping accident occurs, a huge dragging force is applied to the locking arm 22 through the connecting structure 3 of the transmission line walking device. Thus, the insulating net pulls the locking member 23 to rotate along the first direction through the locking arm 22. When the locking member 23 pivots along the first direction, it can apply a pressure towards the second clamping member 12 to the first clamping member 11, thereby clamping the transmission line.

[0048] (2)The locking member 23 is connected to the first clamping member 11, and the locking member 23 can apply pressure to the first clamping member 11 in a timely manner, avoiding the situation where the locking member 23 cannot transmit pressure due to insufficient stroke, and further improving stability and reliability.

[0049] (3)When the clamping device 100 is under the action of an external force, it can quickly respond and automatically trigger the locking mechanism, improving safety.

[0050] (4)The clamping device 100 can press the power transmission cable at the initial stage of the insulating net collapse accident, making the insulating net and the transmission line relatively fixed, and improving the safety of the power line construction.

[0051] Embodiment 2

[0052] As Figure 1 and Figure 2 shown, further, the number of the locking members 23 is multiple, and the multiple locking members 23 are arranged at intervals along the extending direction of the first clamping member 11. The multiple locking members 23 are connected by a connecting rod 24. The connecting rod 24 is connected to the locking arm 22, and the connecting rod 24 can drive the multiple locking members 23 to rotate synchronously under the drive of the locking arm 22. Specifically, each locking member 23 is hinged to the first clamping member 11, and each locking member 23 is also hinged to the connecting rod 24. The end of the connecting rod 24 is also hinged to the locking arm 22. Thus, when the locking arm 22 pulls the connecting rod 24, the connecting rod 24 drives the multiple locking members 23 to rotate simultaneously. Each locking member 23 rotates along the first direction, and each locking member 23 can apply a pressing force towards the second clamping member 12 to the first clamping member 11, thereby improving the clamping effect. By arranging the multiple locking members 23 at intervals, the interference between different locking members 23 can be reduced, and the transmission stability can be improved.

[0053] Here, the extending direction of the first clamping member 11 means that the first clamping member 11 extends along the axial direction of the transmission line, thereby increasing the contact area between the first clamping member 11 and the transmission line and improving the fixing stability.

[0054] As Figure 2 shown, further, one of the locking members 23 is hinged to the end of the connecting rod 24, and the locking member 23 and the connecting rod 24 are pinned by the same pin shaft, thereby reducing the arrangement of parts, simplifying the structure and improving the compactness of the structure.

[0055] Embodiment III

[0056] As shown in Figure 2 Figure, further, the locking member 23 is configured as a cam transmission member, and the cam transmission member has a base circle portion 231, a first convex portion 232, and a second convex portion 233. A pivot shaft 2311 is provided at the center of the base circle portion 231, and the pivot shaft 2311 is used to connect the lock seat 21; the first convex portion 232 and the second convex portion 233 protrude from the base circle portion 231 in the radial direction of the base circle portion 231. The protruding distance of the first convex portion 232 is greater than the protruding distance of the second convex portion 233. The first convex portion 232 can be connected to the locking arm 22, and the second convex portion 233 can be connected to the first clamping member 11. When the locking arm 22 pulls the first convex portion 232, the locking member 23 takes the pivot shaft 2311 as a fulcrum. According to the lever principle, a greater force will be generated at the position where the second convex portion 233 is connected to the first clamping member 11 than the force acting on the locking arm 22, so that a greater pressure can be applied to the first clamping member 11 toward the second clamping member 12, and the transmission line can be clamped more effectively. Secondly, the contour curve of the cam can be designed to make the force transmission smoother. During the process of the locking arm 22 pulling the cam to rotate, the position changes of the first convex portion 232 and the second convex portion 233 can evenly apply the force to the first clamping member 11, avoiding sudden changes in force, which helps to protect the transmission line and the clamping device 100 itself, extends its service life, and also improves the reliability of the entire clamping device 100 during operation.

[0057] In a specific example, the first clamping member 11 has a clamping surface and a connecting surface facing away from the clamping surface. An installation portion is provided on the connecting surface, and the second convex portion 233 is pin-connected to the installation portion through a pin shaft.

[0058] It should be further noted that the protruding distance of the first convex portion 232 refers to the distance between the connection point of the first convex portion 232 and the locking arm 22 and the center of the base circle portion 231, that is, the distance between the connecting pin shaft of the first convex portion 232 and the locking arm 22 and the center of the base circle portion 231; the protruding distance of the second convex portion 233 refers to the distance between the connection point of the second convex portion 233 and the first clamping member 11 and the center of the base circle portion 231, that is, the distance between the connecting pin shaft of the second convex portion 233 and the first clamping member 11 and the center of the base circle portion 231.

[0059] Embodiment IV

[0060] As shown in Figure 3 and Figure 4 Figure, further, the clamping device 100 further includes a first guiding structure 4. The first guiding structure 4 includes a first guiding groove 41 and a first guiding pin 42. The first guiding groove 41 is opened on the lock seat 21, and the first guiding pin 42 passes through the first mounting hole 221 of the locking arm 22. A part of the first guiding pin 42 is located in the first guiding groove 41, and the first guiding pin 42 is in guiding cooperation with the first guiding groove 41.

[0061] Compared with the situation without the first guiding structure 4, when the locking arm 22 is subjected to external forces such as a dragging force, it may move in multiple directions uncertainly, that is, it has a movement with multiple degrees of freedom. By setting the first guiding structure 4, the locking arm 22 moves along a preset path, restricting the degrees of freedom of movement of the locking arm 22. When the locking arm 22 moves along the preset path, it pulls the locking member 23 to rotate in the first direction, thereby improving the stability of the automatic locking mechanism of the clamping device 100.

[0062] As Figure 3 and Figure 4 shown, further, both ends of the first guiding groove 41 are closed in its own extending direction, and the two end portions of the first guiding groove 41 respectively form a first limiting structure 411 and a second limiting structure 412. When the locking arm 22 drives the first guiding pin 42 to move from the first limiting structure 411 to the second limiting structure 412, the locking arm 22 drives the locking member 23 to rotate in the first direction; when the locking arm 22 moves from the second limiting structure 412 to the first limiting structure 411, the locking arm 22 can drive the locking member 23 to rotate in the second direction, and the second direction is opposite to the first direction. That is to say, when the locking arm 22 can drive the locking member 23 to rotate in the second direction, the locking member 23 no longer applies a pressure away from the second clamping member 12 to the first clamping member 11. The first limiting structure 411 and the second limiting structure 412 at both ends of the first guiding groove 41 limit the movement range of the locking arm 22 and the first guiding pin 42. The locking arm 22 can only move between these two limiting structures, avoiding structural damage or functional failure that may be caused by excessive movement of the locking arm 22, and ensuring the stable operation of the clamping device 100 within the designed movement range. Secondly, through the setting of the two limiting structures, precise control of the rotation direction of the locking member 23 is achieved.

[0063] As Figure 5 shown, further, the transmission line traveling device connection structure 3 includes a first mounting seat 31, and the first mounting seat 31 can be connected to the transmission line traveling device 200. A second mounting hole 311 is formed on the first mounting seat 31, and the second mounting hole 311 can be connected to the first guiding pin 42. The clamping device 100 further includes a second guiding structure 5, and the second guiding structure 5 includes a second guiding groove 51 and a second guiding pin 52. The second guiding groove 51 is formed on the first mounting seat 31, the extending direction of the second guiding groove 51 is parallel to the extending direction of the first guiding groove 41, and the extending length of the second guiding groove 51 is not less than the extending length of the first guiding groove 41; a third mounting hole 211 is provided on the locking seat 21, and the second guiding pin 52 can pass through the third mounting hole 211 on the locking seat 21, and the second guiding pin 52 is guidingly engaged in the second guiding groove 51.

[0064] As Figure 6As shown, when a collapse accident occurs to the insulating net, the insulating net drives the first mounting seat 31 to move relative to the locking seat 21. Through the guiding cooperation of the second guiding structure 5, the first mounting seat 31 moves relative to the locking seat 21 along the preset path direction. At the same time, the first mounting seat 31 is also connected to the first guiding pin 42. The first mounting seat 31 drives the first guiding pin 42 to move relative to the locking seat 21, thereby driving the locking arm 22 to move relative to the locking seat 21. Finally, the locking arm 22 drives the locking member 23 to pivot relative to the locking seat 21. By providing the second guiding structure 5, the first mounting seat 31 moves along a preset path, restricting the degree of freedom of movement of the first mounting seat 31. When the first mounting seat 31 moves along the preset path, it pulls the first guiding pin 42 to move, thereby improving the stability of the automatic locking mechanism of the clamping device 100.

[0065] It should be emphasized that the locking seat 21 and the first mounting seat 31 are connected through the first guiding structure 4 and the second guiding structure 5. The locking seat 21 can be more stably supported in the first mounting seat 31, improving the stability and reliability of the structure.

[0066] As Figure 7As shown in the figure, further, the transmission line walking device connection structure 3 includes a second mounting seat 32, the second mounting seat 32 can be connected to the transmission line walking device 200, and the first mounting seat 31 is slidably arranged on the second mounting seat 32 in the vertical direction; the first clamping member 11 is arranged above the second clamping member 12, the first clamping member 11 and the second clamping member 12 are movable in the vertical direction, and the clamping structure 1 further includes a driving mechanism 14, and the driving mechanism 14 is used to apply an upward driving force to the second clamping member 12. Combining the above embodiments, it can be seen that the first guide groove 41 extends in the horizontal direction, the second guide groove 51 extends in the horizontal direction, and the lock seat 21 and the first mounting seat 31 are connected through the first guide structure 4 and the second guide structure 5. Thus, the first mounting seat 31 can drive the clamping member mounting seat 13, the entire locking structure 2 and the first clamping member 11 to move in the vertical direction through the lock seat 21. Therefore, when the transmission line walking device 200 walks on the transmission line, by adjusting the first mounting seat 31, the first clamping member 11 is driven to move upward, so that the first clamping member 11 is spaced apart from the transmission line, avoiding interference between the first clamping member 11 and the transmission line. When it is necessary for the first clamping member 11 and the second clamping member 12 to move in the direction towards each other and clamp the transmission line, the driving mechanism 14 applies an upward driving force to the second clamping member 12 to drive the second clamping member 12 to move upward until the second clamping member 12 abuts against the lower surface of the transmission line; then, the driving mechanism 14 continues to apply an upward driving force to the second clamping member 12. At this time, the transmission line applies a downward reaction force to the clamping member mounting seat 13 through the second clamping member 12. Thus, the clamping member mounting seat 13 moves downward relative to the second clamping member 12, and the clamping member mounting seat 13 drives the first clamping member 11 to move downward through the locking structure 2 until the first clamping member 11 abuts against the upper surface of the transmission line, thereby realizing the clamping of the clamping structure 1 to the transmission line.

[0067] Combined with Figure 8 it can be seen that in a specific example, the transmission line walking device connection structure 3 further includes a fifth guiding structure. The fifth guiding structure includes a fifth linear guide rail extending in the vertical direction arranged on the second mounting seat 32 and a fifth guiding hole opened on the first mounting seat 31, and the fifth guiding hole is slidably mounted on the fifth linear guide rail.

[0068] As Figure 8As shown, further, the connection structure 3 of the transmission line traveling device further includes an auxiliary wheel assembly 33, and the auxiliary wheel assembly 33 is movably installed on the first mounting member in the vertical direction; a spring 34 is provided between the auxiliary wheel assembly 33 and the first mounting seat 31, and the spring 34 is used to apply an elastic force to the auxiliary wheel assembly 33 so that the auxiliary wheel assembly 33 adaptively fits on the surface of the transmission line. Specifically, the spring 34 is compressed between the auxiliary wheel assembly 33 and the first mounting member, and the elastic force of the spring 34 is not only used to adaptively fit the auxiliary wheel assembly 33 on the surface of the transmission line, but also used to drive the first mounting member to move upward, thereby driving the entire locking assembly and the first clamping member 11 away from the upper surface of the transmission line. The second clamping member 12 can move away from the lower surface of the transmission line under the action of gravity. Thus, the stability of the transmission line traveling can be improved.

[0069] Combined with 5 and Figure 8 As shown, in a specific example, the auxiliary wheel assembly 33 includes an auxiliary wheel mounting plate 331 and an auxiliary wheel 332, and the auxiliary wheel 332 is rotatably arranged on the auxiliary wheel mounting plate 332. The installation structure of the netting device 1000 further includes a third guiding structure 35, and the third guiding structure 35 includes a third guiding hole 351 opened on the first mounting seat 31 and a third linear guide rod 352 slidably arranged in the third guiding hole 351; the auxiliary wheel mounting plate is connected to the end of the third linear guide rod 352; the spring 34 is sleeved on the third linear guide rod 352 and abuts against the first mounting seat 31 and the auxiliary wheel mounting plate at both ends respectively.

[0070] Please refer to Figure 2 Further, the clamping member mounting seat includes an upper limit plate 131 and a lower limit plate 132 arranged at intervals in the vertical direction, and both the first clamping member 11 and the second clamping member 12 are movably arranged between the two limit plates; the lock seat 21 is installed on the side of the upper limit plate 131. The upper and lower limit plates are arranged at intervals in the vertical direction, and the first clamping member 11 and the second clamping member 12 are movably limited therebetween.
