[0059] The live fire connection device of the present invention is described in detail below.

[0060] In some embodiments of the present invention, the device further comprises a connection seat 13 (refer to Figure 1 as well as Figure 4 ), the tightening mechanism 12, the main conductor mounting mechanism 40 and the wire clamp holding mechanism 10 are all connected to the connecting seat 13, and the branch line clamping mechanism 20 is connected to the main conductor mounting mechanism 40.

[0061] The wire clamp holding mechanism 10, the tightening mechanism 12, the branch wire holding mechanism 20, the main wire mounting mechanism 40 and the emergency unlocking mechanism 30 are described below respectively.

[0062] 1. Main line mounting mechanism

[0063] The main guide wire mounting mechanism 40 includes two limiter components 40-10. Figure 2 As shown, the position limiting assembly 40-10 includes a locking tongue frame 40-11, a locking tongue 40-12 and a U-shaped guide frame 40-13. The locking tongue frame 40-11 is mounted on the connecting seat 13, and the U-shaped guide frame 40-13 is mounted on the locking tongue frame 40-11. Figure 3 As shown, the lock tongue 40-12 is arranged in a slide groove 40-15 opened at the top of the lock tongue frame 40-11 through a first telescopic spring 40-12-1, the top of the U-shaped guide frame 40-13 seals the slide groove 40-15, and the lock tongue 40-12 is telescoped toward the opening of the U-shaped guide frame 40-13.

Since the locking tongue 40-12 can be retracted, the main conductor slides into the corresponding inner groove of the wire clamp along the U-shaped guide frame 40-13. During this process, the main conductor will press the locking tongue 40-12 until it is under the locking tongue 40-12. After that, the locking tongue 40-12 rebounds and clamps the main conductor, so that the device can be mounted on the wire without manual support.

[0065] 2. Wire clamp holding mechanism

[0066] In some embodiments of the present invention, Figure 4 As shown, the wire clamping mechanism 10 includes a wire clamping assembly, each of which includes a support rod 10-11, the positioning member and the clamping member, wherein the positioning member includes a sleeve 10-10 (refer to Figure 5 ), the clamping member includes a second telescopic spring 10-12-1 and a wire clamp lock tongue 10-12, wherein each lock tongue frame 40-11 has a telescopic slot 40-16 at the lower end (reference Figure 3 ), the two second telescopic springs 10-12-1 are respectively connected to the lower ends of the two U-shaped guide frames 40-13 and are located in the corresponding telescopic slots 40-16.

[0067] The two clamp lock tongues 10-12 are respectively arranged in the two telescopic grooves 40-16 and are in compression contact with the corresponding second telescopic springs 10-12-1. The two side walls of the second clamp housing 11-20 of the clamp 11 are provided with positioning grooves 11-20-2 (refer to Figure 5 ), therefore, when the heads of the two screws 11-30 of the wire clamp 11 are inserted into the sleeve 10-10, the two wire clamp locking tongues 10-12 can be inserted into the two positioning grooves 11-20-2, and the second wire clamp shell 11-20 of the wire clamp 11 is fixed, wherein the support rod 10-11 supports the second wire clamp shell 11-20 of the wire clamp, thereby playing the role of supporting the entire wire clamp 11.

[0068] The sleeve 10-10 is connected to the tightening mechanism 12 and is controlled to rotate by the tightening mechanism 12. The head of the screw 11-30 of the wire clamp can be inserted into the sleeve 10-10 and can rotate along with the sleeve 10-10 when the sleeve 10-10 rotates.

[0069] 3. Tightening mechanism

[0070] like Figure 5 As shown, the wire clamp 11 (this embodiment is described by taking the puncture wire clamp as an example) includes a first wire clamp housing 11-10, a second wire clamp housing 11-20, a screw sleeve 11-21 and a screw 11-30, and the screw sleeve 11-21 is connected to the inside of the second wire clamp housing 11-20. Among them, the outside of the first wire clamp housing 11-10 and the second wire clamp housing 11-20 is provided with a baffle 11-11 (the baffle 11-11 is not fixedly connected to the corresponding wire clamp housing), and the first wire clamp housing 11-10 and the second wire clamp housing 11-20 constitute the housing of the wire clamp 11.

[0071] Among them, in this embodiment, one end of the screw 11-30 (i.e., the tail of the screw 11-30) engages with the threaded hole of the baffle 11-11 outside the first wire clamp housing 11-10 and passes through the baffle 11-11, and the screw 11-30 is also inserted into the screw sleeve 11-21 and also passes through the second wire clamp housing 11-20, and then passes through another baffle 11-11 provided on the outside of the second wire clamp housing 11-20, that is, the head of the screw 11-30 (exemplarily, the head is hexagonal) is located outside the other baffle 11-11, and by rotating the screw 11-30, the screw 11-30 can rotate, and with the cooperation of the screw sleeve 11-21, the first wire clamp housing 11-10 can approach or move away from the second wire clamp housing 11-20. Among them, the head of the screw 11-30 can be inserted into the sleeve 10-10 of the tightening mechanism 12 (described below) and thus be driven, thereby causing the screw sleeve 11-21 to rotate.

[0072] like Figure 5 As shown, the tightening mechanism 12 includes an active component 12-10 (active component 12-10 refers to Figure 1 ), a driven component 12-20 and a fixed seat 12-30, wherein the fixed seat 12-30 is connected to the connecting seat 13, the active component 12-10 and the driven component 12-20 are both connected to the fixed seat 12-30, the driven component 12-20 is connected to the active component 12-10, and the driven component 12-20 is also connected to the sleeve 10-10. When the active component 12-10 moves, the driven component 12-20 follows the movement.

[0073] Among them, Figure 2 As shown, the connecting seat 13 is provided with a through hole 13-10, and the fixing seat 12-30 is The protrusion of the fixing seat 12-30 passes through the through hole 13-10, and the edge of the fixing seat 12-30 is located below the connecting seat 13 and is connected to the connecting seat 13 by a fastening bolt 13-20.

[0074] In some embodiments of the present invention, Figure 5 As shown, the active component 12-10 includes a motor, a flange shaft and a first bevel gear 12-12, wherein the motor is fixedly connected to the connecting seat 13, and the flange shaft is connected to the output end of the motor (the motor is located in the motor housing 12-11 to protect the motor, and the flange shaft is located inside the fixing seat 12-30, so Figure 2 The motor can be powered by a battery installed on the motor housing 12-11, and the motor housing 12-11 and the connecting seat 13 can be fixed), and the first bevel gear 12-12 is connected to the flange shaft. Therefore, when the motor rotates, the first bevel gear 12-12 will rotate.

[0075] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, the driven assembly 12-20 includes a second bevel gear 12-21, a front shell 12-22, a rear shell 12-23, a first spur gear 12-24, a second spur gear 12-25 and a third spur gear 12-26, wherein the front shell 12-22 and the rear shell 12-23 are connected to a fixed seat 12-30, and the front shell 12-22 and the rear shell 12-23 are connected to form an internal space after the connection, and the second bevel gear 12-21, the first spur gear 12-24, the second spur gear 12-25 and the third spur gear 12-26 are all located in the internal space and are connected in the internal space through corresponding rotating shafts.

[0076] Among them, the second bevel gear 12-21 is meshed with the first bevel gear 12-12, the first spur gear 12-24 is coaxially connected with the second bevel gear 12-21, the second spur gear 12-25 and the third spur gear 12-26 are both meshed with the first spur gear 12-24, wherein the second spur gear 12-25 and the third spur gear 12-26 are staggered with each other, so when the first bevel gear 12-12 rotates, the second bevel gear 12-21 can rotate, and the cooperation of the second bevel gear 12-21 and the first bevel gear 12-12 can change the direction of rotation of the output end of the motor. In addition, after the second bevel gear 12-21 rotates, since the first spur gear 12-24 is coaxially connected with the second bevel gear 12-21, the first spur gear 12-24 will rotate, thereby driving the second spur gear 12-25 and the third spur gear 12-26 to rotate synchronously.

[0077] Among them, Figure 5As shown, there are two screw rods 11-30 and two screw sleeves 11-21. In addition, the rotating shafts of the second spur gear 12-25 and the third spur gear 12-26 pass through the front shell 12-22 and are connected to the sleeve 10-10. Therefore, when the second spur gear 12-25 and the third spur gear 12-26 rotate synchronously, the two sleeves 10-10 also rotate synchronously. Since the heads of the two screw rods 11-30 can be directly inserted into the sleeve 10-10 (the sleeve 10-10 The internal space is also exemplarily hexagonal in shape, which is compatible with the head of the screw 11-30). Therefore, when the heads of the two screws 11-30 are inserted into the sleeve 10-10, the two sleeves 10-10 rotate synchronously, which will cause the two screws 11-30 to rotate, thereby driving the first wire clamp shell 11-10 to move, so that the first wire clamp shell 11-10 can be close to or away from the second wire clamp shell 11-20, thereby ultimately adjusting the size of the wire clamp opening to facilitate the insertion of branch lines and the mounting of main lines.

[0078] It should be understood that when the wire clamp is first used, the screw 11-30 can be rotated manually (for example, counterclockwise) to adjust the wire clamp opening to the maximum, and then when the motor is controlled, the sleeve 10-10 can only rotate in the clockwise direction, thereby only driving the screw 11-30 in the opposite direction (for example, clockwise), so that the wire clamp opening can be reduced. In addition, in this embodiment, the head of the screw 10-30 can be set as a copper nut, and the copper nut can be twisted off (it can also be other types of nuts, as long as they can be twisted off). When the copper nut is twisted off, it means that the wire clamp has been tightened, and at this time, the entire wire clamp 11 and the sleeve 10-10 can be in a disengaged state at any time.

[0079] Among them, a rubber ring 12-28 is also provided between the sleeve 10-10 and the corresponding screw 11-30, the main line can be placed in the upper slot 11-20-1 between the first wire clamp shell 11-10 and the second wire clamp shell 11-20, and the branch line is placed in the lower slot 11-20-1 between the first wire clamp shell 11-10 and the second wire clamp shell 11-20.

The rotating member 20-21 is a handle, which is transversely passed through the rotating shaft of the rotating gear 20-18. Rotating the rotating member 20-21 (it should be noted that under the action of the one-way bearing, the rotating direction of the rotating member 20-21 can only be the same direction, for example, only clockwise) can make the rotating gear 20-18 rotate, and the rotating gear 20-18 can drive the rack 20-10 to move, so that the two sliders 20-13 are close to or away from each other.

[0084] In addition, if Figure 4 As shown, a safety plate 20-14-1 may be provided between the two mounting seats 20-14 to cover the rack 20-10, and a knob 20-14-2 may be installed on the handle to facilitate the rotation of the rotating member 20-10.

[0089] Among them, the two servos 30-11 are installed at the bottom of the connecting seat 13 through the servo housing 30-11-1 and are respectively located on both sides of the bottom of the connecting seat 13. One end of the rudder arm 30-12 is installed at the output end of the servo 30-11, and one end of the pull rod 30-13 is rotatably connected to the other end of the rudder arm 30-12. Therefore, when the servo 30-11 is started, the other end of the rudder arm 30-12 can be rotated to a certain angle, thereby driving the pull rod 30-13 to move.

[0090] One end of the first unlocking rod 30-14 is rotatably connected to the other end of the pull rod 30-13, and the other end of the first unlocking rod 30-14 is inserted into the slide groove 40-15 and into the unlocking groove provided at the bottom of the lock tongue 40-12. The first unlocking rod 30-14 is bent, and each bending part of the first unlocking rod 30-14 is rotatably connected to a lock tongue frame 40-11. Therefore, when the pull rod 30-13 moves, the first unlocking rod 30-14 is driven to rotate, so that the lock tongue 40-12 can be extended and retracted in the slide groove (40-15) at the top of the corresponding lock tongue frame 40-11, so that the lock tongue 40-12 of the main wire mounting mechanism can be unlocked, and finally the main wire mounting mechanism can be unlocked to release the main wire.

[0091] In addition, in this embodiment, an inner hole is opened at the other end of the rudder arm 30-12, and a pull ring 30-12-1 is installed in the inner hole. The pull ring 30-12-1 is connected to the emergency unlocking rope 30-12-2. When the motor cannot be remotely controlled, the emergency unlocking purpose can be achieved by pulling down the emergency unlocking rope 30-12-2.

[0092] 5.2 Emergency unlocking mechanism unlocks the branch line clamping mechanism

[0093] In some embodiments of the present invention, Figure 7 As shown, one of the unlocking components 30-10 also includes a fourth spring 30-15, a first connecting rod 30-16 (reference Figure 8 )、second unlocking lever 30-17, locking wheel 30-18, second connecting rod 30-19 (reference Figure 8 ) and the third unlocking lever 30-20 (reference Figure 8 ). Among them, one end of the second unlocking rod 30-17 is a quadrilateral structure, and an unlocking hole 30-17-1 is opened in the middle.

[0094] A first hanging rod 30-14-1 is passed through a side wall of the middle part of one end of the first unlocking rod 30-14, one end of the first connecting rod 30-16 is hinged to one end of the first hanging rod 30-14-1, and the other end of the first connecting rod 30-16 is hinged to one end of the third unlocking member 30-20, the third unlocking member 30-20 is bent, and the bending part of the third unlocking member 30-20 is hinged to the nearby lock tongue frame 40-11, and the other end of the third unlocking rod 30-20 can hook the moving rod 10-12-2 connected to the side of the wire clamp lock tongue 10-12 and can drive the moving rod 10-12-2 to move, wherein, as Figure 7 As shown, the moving rod 10-12-2 passes through the strip groove 40-11-5 of the lock tongue frame 40-11. Therefore, when the first connecting rod 30-16 moves, the third unlocking member 30-20 can be driven to rotate, so that the hooked moving rod 10-12-2 moves, driving the wire clamp lock tongue 10-12 to move, so that the wire clamp clamping mechanism 10 can be unlocked and the entire wire clamp 11 is released.

[0095] 5.3 Emergency unlocking mechanism unlocks the branch line clamping mechanism

[0096] like Figure 8 As shown, one end of the second connecting rod 30-19 is hinged to the other end of the first hanging rod 30-14-1, and the other end of the second connecting rod 30-19 is hinged to the pulling rod 30-19-1. The lower end of the lock tongue frame 40-11 is also provided with an opening groove 40-11-1 (refer to Figure 7 ), the opening slot 40-11-1 is hinged with a rotating arm 40-11-4, and the pulling rod 30-19-1 moves transversely through the rotating arm 40-11-4 and transversely penetrates the unlocking hole 30-17-1. The other end of the second unlocking rod 30-17 is hinged to the side wall of one of the sliders 20-13. One end of the fourth spring 30-15 is connected to one end of the first hanging rod 30-14-1, and the other end of the fourth spring 30-15 is connected to one end of the second unlocking rod 30-17.

[0097] Among them, the other end of the second unlocking rod 30-17 is stuck in the teeth of the locking wheel 30-18, and the locking wheel 30-18 is mounted on a one-way bearing. Therefore, when the rotating part 20-21 is rotated in one direction, the locking wheel 30-18 remains stationary, and the rotating gear 20-18 moves, but the rotating part 20-21 cannot be rotated in the opposite direction. If the second unlocking rod 30-17 is disengaged from the teeth of the locking wheel 30-18, then under the action of the first spring 20-12 of the guide rail 20-11, the two sliders 20-13 move away from each other, and at this time, under the action of the rack 20-10, the rotating gear 20-18 can rotate in the opposite direction, but at this time, under the restriction of the one-way bearing, the entire locking wheel 30-18 will also be driven by the rotating gear 20-18 to rotate in the same direction as the rotating gear 20-18. When the second unlocking lever 30-17 is released, the second unlocking lever 30-17 is pressed again under the pulling force of the fourth spring 30-15 and the locking column locking wheel 30-18. Therefore, by controlling the action of the second unlocking lever 30-17, the branch line clamping structure can be unlocked and the branch line is released.

[0098] 6. Electrical testing and grounding mechanism

[0099] In some embodiments of the present invention, Fig. 9 As shown, the stabilizing mechanism is connected to the connecting seat 13, wherein the stabilizing mechanism includes a hook 60. When a grounding wire clamp needs to be installed on the main conductor to ground the main conductor, the grounding wire clamp is first clamped by the wire clamp clamping mechanism, and it should be noted that while clamping, the upper end of the grounding ring 80 in the grounding wire clamp needs to be kept against the slot 11-20-1 below the wire clamp 11, and then the lower end of the grounding ring 80 is clamped on the hook 60, so that the hook 60 can hook the lower end of the grounding ring 80 to prevent the grounding ring 80 from falling. The hook 60 is connected to the connecting seat 13 through a connecting member 70 (rotational connection, but the rotation angle of the hook 60 can be set as needed, for example, a limit member can be set to prevent the hook 60 from rotating downward too much, thereby causing the lower end of the grounding ring 80 to detach from the hook 60).

[0100] Then, the grounding wire clamp is tightened by the tightening mechanism in turn, so that the main line is clamped by the grounding wire clamp, and the grounding ring 80 is also clamped by the first shell and the second shell of the grounding wire clamp. Then, the grounding wire clamp can be mounted on the main line by unlocking and releasing it through the emergency unlocking mechanism. However, it should be noted that when the grounding wire clamp is installed on the main line, the branch line clamping mechanism of the device does not need to work. In this embodiment, the grounding ring 80 can ensure reliable grounding during maintenance to avoid danger caused by live electricity.

[0101] It should be understood that the hook 60 is not the only option, and any component that can hook the lower end of the grounding ring 80 can be used in the present invention, such as a baffle, a limit plate, etc.

[0102] 7. Work Engineering

[0103] Initially, the distance between the first wire clamp housing 11-10 and the second wire clamp housing 11-2 can be adjusted by rotating the head of the screw rod 11-30. Then the entire wire clamp 11 is installed, and the head of the screw rod 11-30 of the wire clamp 11 is inserted into the sleeve 10-10. At this time, the entire wire clamp 11 is clamped under the action of the wire clamp lock tongue 10-12.

[0104] Then insert the branch line into the slot 11-20-1 below the wire clamp 11, and rotate the rotating part 20-10 to make the two sliders 20-13 approach each other. Finally, the branch line can be clamped by the two first rollers 20-13-1 and the second rollers 20-13-1 approaching each other.

[0105] Through the insulating rod 50 connected to the bottom of the entire device (specifically, the insulating rod 50 is connected to the connecting seat 13 of the entire device through the connecting piece 70), the entire device is dragged upward so that the main conductor can enter the two U-shaped guide frames 40-13. When it begins to enter the slot 11-20-1 above the entire wire clamp 11, the main conductor will press the locking tongue 40-1, and the locking tongue 40-1 will retract so that the main conductor can smoothly enter the corresponding slot 11-20-1. After the main conductor can smoothly enter the corresponding slot 11-20-1, the locking tongue 40-1 extends out. At this time, when the entire device is released, the entire device can be mounted on the main conductor.

[0106] The motor can be started by the remote controller, and the two sleeves 10-10 can be rotated by the motor, so that the distance between the first wire clamp housing 11-10 and the second wire clamp housing 11-2 can be controlled again, so that the wire clamp is tightened.

[0107] When unlocking is required, the servo 30-11 is started by the remote controller, thereby controlling the pull rod 30-13 to move. Under the movement of the pull rod 30-13, the first unlocking rod 30-14, the first connecting rod 30-16 and the second connecting rod 30-19 can be driven to move. The movement of the first unlocking rod 30-14 can unlock the main line mounting mechanism, the movement of the first connecting rod 30-16 can unlock the wire clamping mechanism 10, and the movement of the second connecting rod 30-19 can unlock the branch line clamping mechanism 20, so that the main line, the branch line and the wire clamp can be released in the end. The whole device can fall.

[0108] When remote control operation is not possible, the rudder arm 30-12-1 can be rotated by pulling down the emergency unlocking rope 30-12-2, and each mechanism can be manually unlocked to remove the device.
