Description

Technical Field

[0001] The present invention relates to the technical field of electric power facilities, and in particular to an automatic wire connecting device and an automatic wire connecting method. Background Art

[0002] Existing live operations on distribution networks, such as live access to flow lines, branch line leads, and emergency power lines, mostly use manual live operations. Workers ride on boom trucks or climb concrete poles, wearing insulating gloves and making close contact with live objects to complete the work of fixing leads (instead of guide lines, branch line leads, and emergency power lines) with wire clamps; or they use insulating poles for operations. The former involves the risk of high-altitude operations and personal electric shock, while the latter requires the operation of holding the insulating pole high, which requires the assistance of 2 to 3 people, consumes manpower and takes a long time, and is less efficient.

[0003] To replace manual labor, the prior art discloses a 10 kV live distribution network automatic wire-connecting robot for electrically connecting lead wires and cables. The wiring device comprises: a base, a movably adjustable mounting bracket mounted on the base; a rotatably adjustable cutting mechanism mounted on one side of the mounting bracket; a movably adjustable gripping mechanism mounted on the base and adjacent to the mounting bracket; a rotatably adjustable rope reel mounted on the mounting bracket, on which a wire rope is wound; and a rotatably adjustable winding mechanism mounted on the other side of the mounting bracket. The 10 kV live distribution network automatic wire-connecting robot uses the cutting mechanism to cut the insulation layer of the cable, exposing the wire inside the cable. The gripping mechanism then connects the lead wire to the exposed wire. The winding mechanism then winds the wire rope around the lead wire and cable, achieving an electrical connection between the two. The lead wire installation process requires no human assistance, resulting in high efficiency and safety. However, the wiring device is relatively complex, labor-intensive to carry, and requires numerous steps to operate. While it can replace manual labor, the pre-use preparation is time-consuming, making it less practical and user-friendly. Summary of the Invention

[0048] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the described embodiments are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0049] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0050] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0051] In the description of this embodiment, the terms "upper," "lower," "left," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and are therefore not to be construed as limitations on the present invention. Furthermore, the terms "first," "second," and the like are used solely for descriptive purposes and have no special meaning.

[0052] like Figures 1 to 6 As shown, the automatic wire connecting device according to the embodiment of the present invention includes a hoisting mechanism 100 , a position adjustment mechanism 200 , a wire clamp tightening mechanism 300 and a wire grabbing mechanism 400 .

[0053] The hoisting mechanism 100 includes a mounting frame 110, a first drive assembly 120, and two spaced-apart hoisting belts 130. The first drive assembly 120 is mounted on the mounting frame 110. The hoisting belts 130 span the main conductor 1 and are in transmission connection with the first drive assembly 120. The main conductor 1 extends in the X direction, and the first drive assembly 120 can release or wind up the hoisting belts 130.

[0054] The position adjustment mechanism 200 is mounted on the mounting frame 110. The wire clamp tightening mechanism 300 includes a parallel groove wire clamp 310 and a tightening assembly 320. The tightening assembly 320 is detachably connected to the parallel groove wire clamp 310 and is used to tighten the parallel groove wire clamp 310. The position adjustment mechanism 200 is connected to the tightening assembly 320 to drive the tightening assembly 320 and the parallel groove wire clamp 310 to move along the X direction and the Y direction. The parallel groove wire clamp 310 has a first clamping groove 3101 and a second clamping groove 3102 spaced apart from each other. The X direction is perpendicular to the Y direction.

[0055] The lead grabbing mechanism 400 is connected to the tightening assembly 320 and is used to selectively grab the lead 2; when the lead grabbing mechanism 400 grabs the lead 2, the exposed part of the lead 2 is located in the second clamping groove 3102; when the lead 2 is connected to the main lead 1 through the parallel groove clamp 310, the position adjustment mechanism 200 can drive the tightening assembly 320 to move until it is separated from the parallel groove clamp 310.

[0056] In this embodiment, the two hoisting belts 130 are connected to the first drive assembly 120 after crossing the main conductor 1, and the first drive assembly 120 drives the entire automatic lead-in device to rise or fall. The position adjustment mechanism 200 is used to drive the wire clamp tightening mechanism 300 to move as a whole until the opening of the first clamping groove 3101 of the parallel groove wire clamp 310 is directly opposite the exposed part of the main conductor 1. The hoisting mechanism 100 is then used to drive the automatic lead-in device to move upward as a whole until the exposed part of the main conductor 1 is located within the first clamping groove 3101. The tightening assembly 320 is then used to tighten the parallel groove wire clamp 310 to electrically connect the lead 2 and the main conductor 1. Since the parallel groove wire clamp 310 is fixed to the main conductor 1, the tightening assembly 320 is driven by the position adjustment mechanism 200 to move in a direction away from the parallel groove wire clamp 310, so that the tightening assembly 320 can be separated from the parallel groove wire clamp 310.

[0057] Before the parallel groove clamp 310 is tightened, its first clamping groove 3101 and second clamping groove 3102 are both open, making it impossible to clamp the lead 2 located in the second clamping groove 3102. Therefore, the lead grasping mechanism 400 is required to grasp the lead 2 and position the exposed portion of the lead 2 precisely within the second clamping groove 3102. After the parallel groove clamp 310 is tightened, the lead grasping mechanism 400 releases the lead 2.

[0058] The automatic wire connecting device of this embodiment can realize the automatic connection and conduction of the lead wire 2 and the main wire 1, thereby improving the efficiency and convenience of the wire connecting operation. The automatic wire connecting device of this embodiment has the function of autonomous lifting and lowering. It has a simple structure, is lightweight, and is very portable. In addition, the operation process is simple, and the subsequent maintenance is also simple. It can not only be used in live access to lead wires, branch line leads, emergency power lines and other operation scenarios, but also can take into account other wiring operations by changing the type of wire clamp. Compared with the existing manual wire connecting operation, it can free the operator from the high-risk working environment and greatly improve the efficiency and quality of the wire connecting operation.

[0059] The automatic wire connecting device of this embodiment can promote the automation and intelligent development of live-line operations in distribution networks and can bring huge economic benefits to society.

[0060] Further, if Figure 3 As shown, the first drive assembly 120 includes two first motors 121 and two transmission parts 122. The two first motors 121 are installed on the mounting frame 110 at intervals along the X direction. Each first motor 121 is connected to the two ends of a hoisting belt 130 through a transmission part 122. The first motor 121 can drive the transmission part 122 to synchronously release the hoisting belt 130 or synchronously wind the hoisting belt 130.

[0061] It can be understood that after the hoisting belt 130 crosses the main wire 1, the two ends of the hoisting belt 130 along its length direction are respectively connected to the transmission part 122. When the first motor 121 drives the transmission part 122 to work, the two ends of the hoisting belt 130 can be released at the same time or the two ends of the hoisting belt 130 can be retracted at the same time, thereby improving the rising rate or falling rate of the entire automatic wire connecting device, thereby improving the efficiency of the automatic wire connecting operation.

[0062] The mounting frame 110 includes a base 111 and two brackets 112. The two brackets 112 are fixed to both ends of the base 111 along the X direction. The two first motors 121 are located between the two brackets 112. The brackets 112 have a first side facing the first motors 121 and a second side facing away from the first motors 121.

[0063] The transmission part 122 includes a driving gear 1221 installed on the first side, a first driven gear 1222, two second driven gears 1223 and two reels 1224. The first motor 121 is connected to the driving gear 1221, one of the second driven gears 1223 is meshed with the driving gear 1221, and the first driven gear 1222 is respectively meshed with the driving gear 1221 and the other second driven gear 1223. The shaft hole of each second driven gear 1223 is fixedly connected to a reel 1224, and the two reels 1224 pass through the bracket 112 and are detachably connected to the hoisting belt 130 at both ends along its length direction.

[0064] When the first motor 121 drives the driving gear 1221 to rotate, the driving gear 1221 drives the second driven gear 1223 directly meshing with it to rotate, thereby driving the reel 1224 installed in the shaft hole of the second driven gear 1223 to rotate, and the reel 1224 is used to wind, retract, or release one end of the hoisting belt 130 connected thereto. At the same time, the driving gear 1221 also drives the other second driven gear 1223 to rotate through the first driven gear 1222, thereby driving the reel 1224 installed in the shaft hole of the second driven gear 1223 to rotate, and the reel 1224 is used to wind, retract, or release the other end of the hoisting belt 130 connected thereto. It can be understood that this structural design can make the two second driven gears 1223 rotate in opposite directions, so that the two ends of the hoisting belt 130 can be wound, retracted, or released synchronously.

[0065] For example, the first driven gear 1222 and the driving gear 1221 have the same size, and the two second driven gears 1223 have the same size. The first driven gear 1222 and the driving gear 1221 are symmetrical about a centerline located between them, and the two second driven gears 1223 are also symmetrical about this centerline. The reel 1224 has a connecting hole, through which the hoisting belt 130 passes and is wound around the reel 1224 for a fixed connection.

[0066] Among them, the bracket 112 includes a fixed plate 1121 and a cover plate 1122, the reel 1224 passes through the fixed plate 1121 and is detachably connected to the hoisting belt 130, the cover plate 1122 is buckled on the side of the fixed plate 1121 away from the first motor 121, the fixed plate 1121 has two spaced-apart mounting grooves, the mounting grooves are arc-shaped structures, the two reels 1224 are respectively located in one of the mounting grooves, and the distance between the groove wall of the mounting groove and the outer periphery of the reel 1224 is greater than the maximum winding thickness of the hoisting belt 130 when winding.

[0067] The first drive assembly 120 of this embodiment also includes a wheel cover 123. The outline of the wheel cover 123 is consistent with the outer outline of the transmission part 122. The wheel cover 123 covers the transmission part 122 to protect the transmission part 122 from dust. The first motor 121 passes through the wheel cover 123 and is connected to the driving gear 1221.

[0068] like Figure 4 As shown, the tightening assembly 320 includes a first fixing frame 321, an electric wrench 322 and a drive shaft 323. The electric wrench 322 is installed on the position adjustment mechanism 200 through the first fixing frame 321. One end of the drive shaft 323 is fixedly connected to the electric wrench 322, and the other end is provided with a slot 3231. The parallel groove clamp 310 includes a first clamping plate 311, a second clamping plate 312, a screw 313, an adjusting nut 314 and at least one first guide rod 315. The first guide rod 315 is passed through the first clamping plate 311 and the second clamping plate 312. The length of the first guide rod 315 extends along the Y direction. 311 and the second clamping plate 312 can move along the length direction of the first guide rod 315, the screw 313 passes through the first clamping plate 311 and the second clamping plate 312 and is clamped with the clamping groove 3231, the adjusting nut 314 is fixed on the side of the first clamping plate 311 away from the second clamping plate 312, the adjusting nut 314 is threadedly screwed with the screw 313, and two first clamping grooves 3101 and second clamping grooves 3102 spaced apart from each other are formed between the first clamping plate 311 and the second clamping plate 312. The electric wrench 322 drives the driving shaft 323 to drive the screw 313 to rotate to adjust the distance between the first clamping plate 311 and the second clamping plate 312.

[0069] In this embodiment, the structure and working principle of the electric wrench 322 are similar to those of a motor, and the structure and working principle are conventional technical means in this field, and will not be described in detail.

[0070] In this embodiment, the first clamping plate 311 and the second clamping plate 312 each have a through-hole for the first guide rod 315 to pass through, and the first clamping plate 311 and the second clamping plate 312 are movable along the length of the first guide rod 315. Because the adjusting nut 314 is fixed to the first clamping plate 311 and is threadedly connected to the screw 313, when the electric wrench 322 drives the drive shaft 323 to rotate to tighten the parallel groove cable clamp 310, the drive shaft 323 rotates the screw 313 engaged therewith, causing the adjusting nut 314 to push the first clamping plate 311 toward the second clamping plate 312, thereby achieving the tightening operation.

[0071] The provision of the first guide rods 315 prevents the first clamping plate 311 and / or the second clamping plate 312 from rotating about the screw 313 and affecting the engagement of the parallel groove clamp 310 with the lead 2 / main lead 1. The number of first guide rods 315 is not limited to one. Exemplarily, the number of first guide rods 315 is two, symmetrically disposed on either side of the adjustment nut 314 along the X-direction.

[0072] Furthermore, the first fixing frame 321 includes a support frame 3211 and a support plate 3212, the support frame 3211 is connected to the position adjustment mechanism 200, the electric wrench 322 is mounted on the support frame 3211, the support plate 3212 is fixed on the support frame 3211, the card slot 3231 is a non-circular structure, the screw 313 includes a screw body 3131 and a card cap 3132 connected to one end of the screw body 3131, and the card cap 3132 is connected to the card slot. 3231 cooperates with each other, the card cap 3132 passes through the support plate 3212 and is engaged with the card slot 3231, and two plug-in protrusions 316 are provided at intervals on the side of the second clamping plate 312 facing the support plate 3212, and a plug-in hole 3213 is provided on the support plate 3212 corresponding to the plug-in protrusion 316. The position adjustment mechanism 200 can drive the card cap 3132 to exit the card slot 3231 along the Y direction and the plug-in protrusion 316 to exit the plug-in hole 3213 along the Y direction.

[0073] By configuring the cap 3132 and the slot 3231 in a non-circular configuration, this embodiment prevents relative movement between the cap 3132 and the slot 3231 in directions other than the Y direction. Furthermore, the mating engagement of the protruding portion 316 on one side of the second clamping plate 312 with the insertion hole 3213 on the support plate 3212 enhances the connection stability between the cap 3132 and the slot 3231 in directions other than the Y direction, preventing the cap 3132 from tilting relative to the slot 3231 and potentially affecting the disengagement (separation) between the tightening assembly 320 and the parallel groove clamp 310.

[0074] The two plugging protrusions 316 are symmetrically arranged on both sides of the card cap 3132 along the Z direction. Correspondingly, the two plugging holes 3213 are symmetrically arranged on both sides of the card slot 3231 along the Z direction. The X direction, the Y direction and the Z direction are perpendicular to each other.

[0075] Furthermore, a limiting portion 317 is provided on the side of the first clamping plate 311 facing away from the second clamping plate 312, and the limiting portion 317 includes a first connecting plate 3171, two limiting plates 3172 and two stops 3173. The two limiting plates 3172 are spaced apart on the side of the first connecting plate 3171 facing away from the first clamping plate 311, and the stop block 3173 is fixed to one end of the limiting plate 3172 away from the first connecting plate 3171. A limiting groove is formed between the two limiting plates 3172, and the adjusting nut 314 is located in the limiting groove, and the outer periphery of the adjusting nut 314 contacts the two limiting plates 3172, and the two ends of the adjusting nut 314 along the Y direction contact the first connecting plate 3171 and the stop block 3173 respectively.

[0076] Because the outer periphery of the adjusting nut 314 contacts the two limiting plates 3172, and the ends of the adjusting nut 314 along the Y direction contact the first connecting plate 3171 and the stopper 3173, respectively, the adjusting nut 314 is limited in its rotation relative to the screw rod 313. As the screw rod 313 rotates, the adjusting nut 314 can only move along the length of the screw rod 313. When the adjusting nut 314 moves toward the second clamping plate 312, the adjusting nut 314 contacts the first clamping plate 311, driving the first clamping plate 311 toward the second clamping plate 312.

[0077] Optionally, the outer periphery of the adjusting nut 314 has a hexagonal structure, with its two upper and lower opposing outer side surfaces contacting the inner walls of two spaced-apart stop plates 3172. One end of the adjusting nut 314 along its length (the Y direction in the figure) contacts the side wall of the first connecting plate 3171, and the other end contacts the inner wall of the stop block 3173. In other embodiments, the outer periphery of the adjusting nut 314 may also have a quadrilateral structure, such as a square, rectangle, or trapezoid, with two upper and lower flat surfaces contacting the inner walls of the stop plates 3172.

[0078] Among them, two first arc-shaped grooves are provided on the side of the first clamping plate 311 facing the second clamping plate 312, and the two first arc-shaped grooves are arranged at intervals along the Z direction. Two second arc-shaped grooves are provided on the side of the second clamping plate 312 facing the first clamping plate 311. When the first clamping plate 311 and the second clamping plate 312 are clamped, the exposed part of the lead 2 is located in the second clamping groove 3102 composed of the first arc-shaped groove and the second arc-shaped groove below, and the exposed part of the main wire 1 is located in the first clamping groove 3101 composed of the first arc-shaped groove and the second arc-shaped groove above.

[0079] Furthermore, the inner circumferences of the first and second arcuate grooves are each provided with a tooth-shaped structure. The tooth-shaped structure is formed by a plurality of spaced-apart, protruding strips extending in the X direction. By designing the inner circumferences of the first and second arcuate grooves as tooth-shaped structures, the friction between the exposed portion of the lead 2 and the second clamping groove 3102 of the parallel groove clamp 310, as well as the friction between the exposed portion of the main lead 1 and the first clamping groove 3101 of the parallel groove clamp 310, can be increased, thereby improving the connection stability between the lead 2 / main lead 1 and the parallel groove clamp 310.

[0080] Further, if Figure 5 As shown, the lead grabbing mechanism 400 includes a second drive component 410 and a clamping portion 420. The second drive component 410 is installed on one side of the support plate 3212 along the X direction. The second drive component 410 is transmission-connected to the clamping portion 420 for driving the clamping portion 420 to open or close. When the clamping portion 420 clamps the lead 2, the exposed portion of the lead 2 is located in the second clamping groove 3102.

[0081] The clamping portion 420 is located on one side of the support plate 3212 and is adjacent to the parallel groove wire clamp 310, and the position of the clamping portion 420 for grabbing the lead 2 corresponds to the second clamping groove 3102 of the parallel groove wire clamp 310, and the two are in the same horizontal plane. When the clamping portion 420 clamps the lead 2, by adjusting the position of the clamping portion 420 grabbing the lead 2, the exposed part of the lead 2 can be exactly located in the second clamping groove 3102 of the parallel groove wire clamp 310.

[0082] Furthermore, the second drive assembly 410 includes a second fixed frame 411, a second motor 412, a first screw rod 413 and at least one second guide rod 414. The second fixed frame 411 is fixedly connected to one side of the support plate 3212 along the X direction. The second motor 412 is installed on the second fixed frame 411 and is transmission-connected to the first screw rod 413. The clamping portion 420 includes two clamping jaws spaced apart up and down. The second guide rod 414 is passed through the two clamping jaws, one of which is transmission-connected to the first screw rod 413, and the other clamping jaw is fixedly connected to the second guide rod 414. The second motor 412 can drive the first screw rod 413 to rotate to adjust the distance between the two clamping jaws.

[0083] Among them, the second fixed frame 411 includes a vertical plate 4111 and two horizontal plates 4112. The two horizontal plates 4112 are spaced apart from each other and vertically connected to the vertical plate 4111. The second motor 412 is installed on the horizontal plate 4112 located above. The first screw rod 413 is sequentially passed through the horizontal plate 4112, the two clamping jaws and the horizontal plate 4112 from top to bottom. The first screw rod 413 is rotatably connected to the two horizontal plates 4112. The two ends of the second guide rod 414 are respectively vertically connected to the two horizontal plates 4112. The two clamping jaws are respectively an upper clamping jaw 421 and a lower clamping jaw 422.

[0084] In this embodiment, when the upper clamping jaw 421 is transmission-connected to the first screw rod 413 , the lower clamping jaw 422 is fixed relative to the first screw rod 413 and the second guide rod 414 , and the second motor 412 can drive the first screw rod 413 to rotate, thereby driving the upper clamping jaw 421 to move up and down along the second guide rod 414 .

[0085] In this embodiment, the upper jaw 421 has a first V-shaped groove with a downward opening, and the lower jaw 422 has a second V-shaped groove with an upward opening. The opening of the first V-shaped groove directly faces the opening of the second V-shaped groove. When the lead 2 is placed in the second V-shaped groove, the second motor 412 is driven to move the upper jaw 421 downward toward the lower jaw 422, causing the lead 2 to abut against the walls of the first and second V-shaped grooves, respectively, thereby grasping the lead 2.

[0086] In other embodiments, the upper clamping jaw 421 is fixed relative to the first screw rod 413 and the second guide rod 414, and the lower clamping jaw 422 is transmission-connected to the first screw rod 413. The second motor 412 can drive the first screw rod 413 to rotate, thereby driving the lower clamping jaw 422 to move up and down along the second guide rod 414. Accordingly, when the lead 2 is placed in the second V-shaped groove, the second motor 412 is driven to drive the lower clamping jaw 422 and the lead 2 to move upward toward the upper clamping jaw 421, so that the lead 2 abuts against the groove walls of the first V-shaped groove and the second V-shaped groove, thereby grasping the lead 2.

[0087] Furthermore, the groove walls of the first V-shaped groove and the second V-shaped groove are respectively provided with a plurality of anti-slip protrusions at intervals, and the provision of the anti-slip protrusions can improve the gripping stability of the lead 2. For example, the plurality of anti-slip protrusions are spaced apart along the X direction.

[0088] Among them, there are two second guide rods 414, and the two second guide rods 414 are symmetrically arranged on both sides of the first screw rod 413, which are used to realize the movement guidance of one of the clamps along the Z direction, so as to avoid the upper clamp 421 or the lower clamp 422 from rotating during the up and down movement and affecting the grasping stability of the lead 2.

[0089] Furthermore, if Figure 6 As shown, the position adjustment mechanism 200 includes a Y-axis drive component 210, a first base plate 220, an X-axis drive component 230 and a second base plate 240 arranged in sequence from bottom to top along the Z direction.

The second connecting block 233 is fixed to the bottom of the second base plate 240.

[0092] The third motor 211 can drive the second screw rod 212 to rotate, thereby driving the first connecting block 213 and the first base plate 220 to move in the Y direction, thereby driving the wire clamp tightening mechanism 300 to move until the main conductor 1 is located in the first clamping groove 3101 of the parallel groove wire clamp 310, or driving the tightening assembly 320 of the wire clamp tightening mechanism 300 to move and separate from the parallel groove wire clamp 310. The fourth motor 231 can drive the third screw rod 232 to rotate, thereby driving the second connecting block 233 and the second base plate 240 to move in the X direction, thereby driving the wire clamp tightening mechanism 300 to move in the X direction until the opening of the first clamping groove 3101 for clamping the main conductor 1 is exactly located at the exposed portion of the main conductor 1.

[0093] Exemplarily, the Y-axis drive assembly 210 also includes a third fixed frame 214, which is a rectangular frame structure, including two first fixed parts 2141 arranged opposite to each other along the X direction and two second fixed parts 2142 arranged opposite to each other along the Y direction.

[0097] This embodiment also provides an automatic wire-connecting method, which uses the automatic wire-connecting device of the above embodiment. The automatic wire-connecting method includes the following steps:

[0098] Place two hoisting belts 130 across the main conductor 1 so that the exposed portion of the main conductor 1 is located between the two hoisting belts 130 , and connect both ends (the two free ends along their length) of the two hoisting belts 130 to the first drive assembly 120 , respectively.

[0099] Insert the parallel groove clamp 310 into one side of the tightening assembly 320;

[0100] The first drive assembly 120 is started to wind the hoist belt 130 so that the automatic lead-connecting device as a whole rises to a first height position. The first drive assembly 120 is then stopped. The lead wire 2 is then grasped by the lead wire grasping mechanism 400, and the exposed portion of the lead wire 2 is positioned within the second clamping groove 3102. The first height position is a position at which the operator can conveniently grasp the lead wire 2 using the lead wire grasping mechanism 400. The specific height position can be determined based on actual conditions and will not be further described.

[0101] The first drive assembly 120 is then started to wind the hoisting belt 130, causing the automatic wire connecting device to rise as a whole until it is close to the main wire 1. The first drive assembly 120 is then stopped, and the position of the parallel groove clamp 310 is adjusted using the position adjustment mechanism 200 so that the exposed portion of the main wire 1 is located above the first clamping groove 3101.

[0104] The position adjustment mechanism 200 is used to drive the tightening assembly 320 to move in the Y direction away from the parallel groove cable clamp 310, so that the tightening assembly 320 is separated from the parallel groove cable clamp 310. That is, the cap 3132 of the screw rod 313 of the parallel groove cable clamp 310 is driven to exit the locking groove 3231 at the end of the driving shaft 323 of the tightening assembly 320 in the Y direction, and the plug-in protrusion 316 of the parallel groove cable clamp 310 is driven to exit the plug-in hole 3213 formed on the support plate 3212 of the first fixing frame 321 of the tightening assembly 320 in the Y direction.
