Description

Technical Field

[0001] This invention relates to the field of cable head splicing technology, and more particularly to an auxiliary device for cable head splicing. Background Technology

[0002] When connecting the electrical cabinet to the underground cable, the existing wiring method is to first place an auxiliary tool between the cable port of the electrical cabinet and the cable well on the ground, then manually pull the underground cable up through the cable well on the ground and connect it to the auxiliary tool. The personnel make the cable head at the upper end of the cable. After the head is made, the auxiliary tool drives the cable upward, and the cable enters the electrical cabinet through the cable port. Finally, the personnel connect the cable head to the electrical components inside the electrical cabinet.

[0003] The existing auxiliary fixtures are too tall and inconvenient to move, easily causing interference with the electrical cabinet, and are difficult to move between the cable well and the cable outlet. Summary of the Invention

[0004] In order to solve the shortcomings of existing auxiliary tooling that easily interferes with electrical cabinets and is inconvenient to move, this invention proposes a cable head splicing auxiliary device that is less likely to interfere with electrical cabinets and is easy to move.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable head splicing auxiliary device includes an upper base with a cable threading port on the upper base. A first cable outlet is provided on one side of the cable threading port. A first clamping roller and a second clamping roller are disposed inside the cable threading port. The axes of the first clamping roller and the second clamping roller are parallel. The upper base is provided with a driving device for driving the first clamping roller. A bracket is slidably connected inside the cable threading port. The second clamping roller is rotatably connected to the bracket. The upper base is provided with a sliding device for driving the bracket to slide along the cable threading port.

[0007] With the above setup, cable lifting and lowering can be achieved. Specifically, the cable is moved between the electrical cabinet and the cable well, and then the cable under the cable well is manually pulled upwards and passed between the first and second clamping rollers. Under the action of the sliding device, the bracket moves along the cable entry to the first clamping roller, and the bracket drives the second clamping roller to move towards the first clamping roller. Finally, the first and second clamping rollers clamp the cable. At this time, the cable is fixed between the first and second clamping rollers, and the cable can be released. A cable head is made at the upper end of the cable. Then, the driving device drives the first clamping roller to rotate around its axis. Under the action of friction, the cable moves upwards, and the second clamping roller rotates accordingly around its axis. The cable passes upwards through the cable opening on the lower side of the electrical cabinet and approaches the electrical components inside the electrical cabinet. Then, personnel connect the cable head to the electrical components. After the connection is completed, under the action of the sliding device, the bracket and the second clamping roller move away from the first clamping roller. The first clamping roller and the second clamping roller separate the cable, and then the cable leaves the upper base from the first outlet, thereby separating the cable from this application, and finally removing this application from between the electrical cabinet and the cable well.

[0008] Furthermore, two sliding seats are slidably connected to the upper side of the upper base, the wire threading port is disposed between the sliding seats, a blade is fixedly connected to the side of the sliding seat near the wire threading port, and the upper base is provided with a control device for controlling the sliding seats to move closer to or away from the wire threading port.

[0009] With the above setup, the cable can be stripped, facilitating the fabrication of cable heads. Specifically, when the cable is clamped by the first and second clamping rollers, the upper end of the cable is positioned between the two blades. The cable includes the conductor and the insulation layer covering the conductor. Under the control of the control device, the two sliding seats move closer together, causing the two blades to move closer together and cut into the cutting layer. The plane of the blades is perpendicular to the axis of the first clamping roller. Then, under the action of the drive device, the first clamping roller rotates, driving the cable upward. As the cable moves upward, the insulation layer of the cable is cut from top to bottom by the blades. When the cutting length reaches a certain value, under the action of the control device, the two sliding seats move away from each other, causing the blades to separate. Under the action of the drive device, the first clamping roller continues to drive the cable upward and through the cable opening. At this time, since the insulation layers on both sides of the upper end of the cable are cut, the insulation layers can be peeled off like peeling a banana. Then, the peeled insulation layers are cut off with scissors to expose the wires, which is convenient for making cable heads. After the cable head is connected to the electrical components, the first clamping roller and the second clamping roller separate and loosen the cable. Then, the cable leaves the application from the first outlet.

[0010] Furthermore, a support plate is provided on the side of the sliding seat away from the wire insertion port. The support plate is fixedly connected to the upper base. A first guide sleeve is fixedly connected to the support plate. A first guide rod is slidably connected inside the first guide sleeve. The first guide rod is fixedly connected to the sliding seat.

[0011] The above settings make the sliding seat slide more stably along the upper base. Specifically, the axis of the first guide sleeve is perpendicular to the axis of the first clamping roller, the first guide rod is coaxial with the first guide sleeve, and the axis of the first guide rod is parallel to the upper side of the upper base.

[0012] Furthermore, the control device includes a first screw that passes through and is threadedly connected to the sliding seat, the axis of the first screw being parallel to the axis of the first guide rod.

[0013] With the above settings, when it is necessary to drive the sliding seat, the first screw is rotated, and the first screw and the sliding seat rotate relative to each other. When the first screw and the sliding seat are threadedly connected, the sliding seat moves along the axial direction of the first screw.

[0014] Furthermore, a first bevel gear and a second bevel gear are rotatably connected inside the support plate. The first bevel gear is fixedly connected to the first screw, and the first bevel gear and the second bevel gear mesh. A drive screw is fixedly connected to the second bevel gear, and one end of the drive screw is located on the side of the support plate.

[0015] With the above configuration, the first screw can be rotated easily. Specifically, the end of the drive screw away from the second bevel gear is located on the same side of the upper base, which makes it convenient for personnel on one side of the upper base to control the movement of the two sliding seats respectively. Specifically, personnel use an electric screwdriver to rotate the drive screw, and the drive screw drives the first screw to rotate through the second bevel gear and the first bevel gear.

[0016] Furthermore, a driven gear is fixedly connected to one end of the first clamping roller, and the driving device includes a drive motor disposed on one side of the upper base. The drive motor is connected to a drive gear, and the drive gear meshes with the driven gear. The radius of the drive gear is smaller than the radius of the driven gear.

[0017] With the above settings, the first clamping roller can be rotated stably. Specifically, the drive motor drives the first clamping roller to rotate through the drive gear and the driven gear. When the radius of the drive gear is smaller than the radius of the driven gear, the power of the drive motor can be reduced. In addition, the drive motor can be set to a motor with a self-locking function to prevent the cable from slipping back.

[0018] Furthermore, the radius of the first clamping roller gradually increases from the middle to both ends, and the radius of the second clamping roller gradually increases from the middle to both ends.

[0019] The above settings prevent the cable from shifting laterally during its ascent. Specifically, when the cable is clamped by the first and second clamping rollers, it is located roughly in the middle of the first and second clamping rollers. Since the gap between the first and second clamping rollers gradually decreases from the middle to both ends, the cable will not shift to either end.

[0020] Furthermore, the bracket is U-shaped with its opening facing the first wire clamping roller. The second wire clamping roller is rotatably connected between the two ends of the bracket. The upper base is provided with a threaded groove. The sliding device includes a second screw rotatably connected to the bracket. The axis of the second screw is perpendicular to the axis of the first wire clamping roller. The end of the second screw away from the bracket is threadedly connected to the threaded groove and fixedly connected to a drive rod. The cross-section of the drive rod is square. A drive wheel is sleeved on the drive rod. The drive wheel is provided with a drive groove adapted to the drive rod. The drive rod passes through the drive groove and is slidably connected to the drive groove. The drive wheel is rotatably connected to one side of the upper base. The drive wheel is threadedly connected to a fixing bolt, and the fixing bolt abuts against the upper base.

[0021] With the above configuration, when the support needs to be driven, the drive wheel is rotated, and the drive wheel drives the second screw to rotate via the drive rod. When the second screw and the threaded groove rotate relative to each other, the second screw moves along the axis of the second screw. Since the second screw and the support are rotatably connected, the second screw drives the support to move closer to or away from the first clamping roller. The second screw and the drive rod are integrally formed, and the cross-section of the drive rod is square, thereby realizing the transmission between the drive rod and the drive wheel. The drive rod and the drive groove are slidably connected, so when the second screw moves along the axis of the second screw, the drive rod also moves along the axis of the second screw. The drive rod and the drive groove slide relative to each other. When the fixing bolt is tightened, the fixing bolt and the upper base abut against each other. Under the action of friction, the drive wheel is prevented from rotating, thereby preventing the second screw from rotating, and thus preventing the distance between the first clamping roller and the second clamping roller from changing. When the fixing bolt is loosened, the drive wheel can rotate freely.

[0022] Furthermore, rollers are provided below the upper base.

[0023] The above settings facilitate the relocation of this application.

[0024] Furthermore, a lower base is provided below the upper base, and the lower base and the upper base are connected by a telescopic rod extending vertically. The driving device is also used to drive the upper base to lift and lower.

[0025] The height of this application can be adjusted through the above settings, thereby further facilitating its movement. Specifically, initially, the distance between the upper and lower bases is small, resulting in a smaller height for this application, making it less likely to interfere with the electrical cabinet and facilitating its placement between the cable port and cable well of the electrical cabinet. Once the application is in place, the upper base moves upward and closer to the cable port under the action of the drive device. As the upper base moves upward, the gap between the upper and lower bases widens, making it easier for personnel to pull up the cable in the cable well through the gap between the upper and lower bases. The drive device is also used to drive the lifting and lowering of the upper base, thereby increasing the compactness of the structure of this application.

[0026] Furthermore, the telescopic rod includes a second guide sleeve whose lower end is fixedly connected to the lower base, a second guide rod which is slidably connected inside the second guide sleeve, and the upper end of the second guide rod is fixedly connected to the upper base.

[0027] The above settings make the lifting and lowering of the upper base more stable.

[0028] Furthermore, a limiting groove is provided on the inner side of the second guide sleeve, and a limiting protrusion is fixedly connected to the second guide rod, with the limiting protrusion slidably connected within the limiting groove.

[0029] The above settings prevent the second guide rod from being pulled upwards out of the second guide sleeve.

[0030] Furthermore, the lower base includes two parallel support beams, the extension direction of which is perpendicular to the axis of the first clamping roller. The support beams are fixedly connected by a first rotating shaft and a second rotating shaft, which are parallel to each other and located at both ends of the support beams. One of the support beams has a second cable outlet, which divides the corresponding support beam into two sub-beams. The first rotating shaft is fitted with a first rotating sleeve, which has a first fixing device for fixing the first rotating sleeve to the first rotating shaft. The second rotating shaft is fitted with a second rotating sleeve, which has a second fixing device for fixing the second rotating sleeve to the second rotating shaft. A first rotating rod is fixedly connected to both ends of the first rotating sleeve, and a second rotating rod is fixedly connected to both ends of the second rotating sleeve. The end of the first rotating rod away from the first rotating sleeve extends downward at an angle toward the second rotating sleeve and is rotatably connected to the roller. The end of the second rotating rod away from the second rotating sleeve extends downward at an angle toward the first rotating sleeve and is rotatably connected to the roller.

[0031] With the above configuration, the rollers can be positioned on the underside of the lower base, thereby facilitating the movement of this application.

[0032] Furthermore, the first fixing device includes a first bolt threadedly connected to the first rotating sleeve, the first rotating shaft is provided with a first threaded hole, and one end of the first bolt is inserted into the first threaded hole. The second fixing device includes a second bolt threadedly connected to the second rotating sleeve, the second rotating shaft is provided with a second threaded hole, and one end of the second bolt is inserted into the second threaded hole.

[0033] The above configuration achieves the fixation of the first rotating sleeve and the first rotating shaft, as well as the fixation of the second rotating sleeve and the second rotating shaft. When the first bolt is loosened and the first bolt is disengaged from the first threaded hole, the first rotating sleeve and the first rotating shaft can rotate relative to each other. When the second bolt is loosened and the second bolt is disengaged from the second threaded hole, the second rotating sleeve and the second rotating shaft can rotate relative to each other.

[0034] Furthermore, the driving device is connected to the first rotating sleeve via a transmission device and is used to drive the first rotating sleeve to rotate; the driving device is connected to the second rotating sleeve via the transmission device and is used to drive the second rotating sleeve to rotate.

[0035] The drive device drives the first rotating rod and the second rotating rod to rotate upward through the transmission device, thereby pushing the upper base to move upward.

[0036] With the above configuration, the first and second rotating rods can rotate upwards and push the upper base upwards. Specifically, the length of the first rotating rod is less than the shortest distance between the first and second rotating sleeves, so that when the first rotating rod rotates upwards, the first rotating rod and the corresponding roller will not interfere with the second rotating sleeve. The length of the second rotating rod is less than the shortest distance between the first and second rotating sleeves, so that when the second rotating rod rotates upwards, the second rotating rod and the corresponding roller will not interfere with the first rotating sleeve.

[0037] After the cable moves between the cable outlet and the cable well, the first and second bolts are loosened. Then, under the action of the drive device, the first and second rotating rods rotate upward and raise the upper base. After the first and second rotating rods raise the upper base, the limiting protrusion approaches the upper end of the limiting groove, the roller abuts against the lower side of the upper base, and the lower side of the lower base abuts against the ground, thereby preventing the cable from shifting. Then the cable extends from the cable well and passes between the second rotating rods. At this time, the upper end of the cable is located between the first and second clamping rollers. Under the action of the sliding device, the first and second clamping rollers approach and clamp the cable. After the cable is clamped by the first and second clamping rollers, the upper end of the cable is located between the two blades. The cable includes a conductor and an insulation layer covering the outside of the conductor. Under the action of the control device, the two sliding seats approach each other, driving the two blades to approach each other and cut into the cutting layer. The plane of the blades is perpendicular to the axis of the first clamping roller. Then, under the action of the drive device, the first clamping roller rotates and drives the cable to move closer to the upper end of the cable. As the cable moves upward, its insulation layer is cut from top to bottom by the blades. When the cut length reaches a certain value, the two sliding seats move away from each other under the action of the control device, causing the blades to separate. Under the action of the drive device, the first clamping roller continues to drive the cable upward and through the cable opening. At this time, since the insulation layers on both sides of the upper end of the cable have been cut, the insulation layer can be peeled off like peeling a banana. Then, the peeled insulation layer is cut off with scissors to expose the wires, making it easier to make a cable head. After the cable head is connected to the electrical components, the first clamping roller and the second clamping roller separate and loosen the cable.

[0038] When it is necessary to disconnect the cable from this application, this application returns to its initial state. That is, under the action of the driving device, the first rotating sleeve and the second rotating sleeve rotate, driving the first rotating rod and the second rotating rod to rotate downward and raise the lower base. When the first bolt and the first threaded hole are aligned, the first bolt is tightened to fix the first rotating sleeve and the first rotating shaft. When the second bolt and the second threaded hole are aligned, the second bolt is tightened to fix the second rotating sleeve and the second rotating shaft. A first positioning block 41 can be provided on the side of the first rotating sleeve away from the second rotating sleeve. The first positioning block 41 is fixedly connected to the support beam. A second positioning block 42 is fixedly connected to the outside of the first rotating sleeve. When the upper side of the second positioning block 42 abuts against the first positioning block 41, the first threaded hole and the first bolt are aligned. A third positioning block 43 can be provided on the side of the second rotating sleeve away from the first rotating sleeve. The third positioning block 43 is fixedly connected to the support beam. A fourth positioning block 44 is fixedly connected to the outside of the second rotating sleeve. When the upper sides of the third positioning block 43 and the fourth positioning block 44 abut against each other, the second bolt and the second threaded hole are aligned. When the lower base is raised by the first and second rotating rods, the lower base separates from the ground, the rollers abut against the ground, the telescopic rod shortens, and the limiting protrusion slides down along the limiting groove and approaches the lower end of the limiting groove. At this time, a first clearance opening is formed between the second rotating rod and the first rotating sleeve, a first clearance space is formed between the first rotating rod and the second rotating rod, a second clearance opening is formed between the second rotating sleeve and the first rotating rod, and a second clearance space is formed between the first rotating rod and the dividing beam. The cable separates from the upper base from the first outlet. The cable passes through the first clearance opening, the second clearance space, the second clearance opening, the second clearance space, the second outlet, and the lower base in sequence, thus completing the separation of the cable from this application.

[0039] Furthermore, a first limiting block and a second limiting block are fixedly connected to the lower side of the upper base. The first limiting block is located on the side of the first wire clamping roller away from the second wire clamping roller, and the second limiting block is located on the side of the second wire clamping roller away from the first wire clamping roller. The first limiting block is provided with a first stop surface and a first guide surface for guiding the roller on the second rotating rod to the first stop surface. The first stop surface is located at the end of the first limiting block near the threading opening, and the first guide surface is located on the side of the first stop surface away from the threading opening. The end of the first guide surface near the first stop surface is inclined downward and connected to the lower end of the first stop surface. The second limiting block is provided with a second stop surface and a second guide surface for guiding the roller on the first rotating rod to the second stop surface. The second stop surface is located at the end of the second limiting block near the threading opening, and the second guide surface is located on the side of the second stop surface away from the threading opening. The end of the second guide surface near the threading opening is inclined downward and connected to the lower end of the second stop surface.

[0040] The first stop surface is an arc surface. When the roller of the second rotating rod abuts against the first stop surface, the axis of the first stop surface coincides with the axis of the second rotating shaft.

[0041] The second stop surface is an arc surface. When the roller of the first rotating rod abuts against the second stop surface, the axis of the second stop surface coincides with the axis of the first rotating shaft.

[0042] Through the above configuration, stable support for the upper base can be achieved by the first and second rotating rods. Specifically, during the upward rotation of the first rotating rod, the roller of the first rotating rod abuts against the upper base and lifts the upper base. As the first rotating rod continues to rotate upward, the roller passes the second guide surface and moves to the second stop surface. Under the action of gravity, the upper base moves downward and abuts against the roller. At this time, the roller of the first rotating rod and the second stop surface are in contact. Similarly, during the upward rotation of the second rotating rod, the roller of the second rotating rod abuts against the upper base and lifts the upper base. As the second rotating rod continues to rotate upward, the roller passes the first guide surface and moves to the first stop surface. Under the action of gravity, the upper base moves downward and abuts against the roller. At this time, under the action of the gravity of the upper base and the cable, the roller of the first rotating rod is stuck between the second stop surface and the upper base, and the roller of the second rotating rod is stuck between the first stop surface and the upper base. The first and second rotating rods provide good support for the upper base.

[0043] Furthermore, the transmission device includes a first transmission shaft, one end of which is fixedly connected to a first transmission bevel gear, and the other end of which is fixedly connected to a second transmission bevel gear. One end of a first rotating sleeve is fixedly connected to a third transmission bevel gear, and one end of a second rotating sleeve is fixedly connected to a fourth transmission bevel gear. The first and third transmission bevel gears mesh, as do the second and fourth transmission bevel gears. A damping sleeve is fitted onto the first transmission shaft, and damping oil is disposed between the damping sleeve and the first transmission shaft. Two annular protrusions are fixedly connected to the first transmission shaft, and the damping sleeve is disposed between these annular protrusions. The outer side of the damping sleeve is fixedly... The transmission device includes a bushing fixedly connected to the support beam and a second transmission shaft passing through the bushing. The second transmission shaft extends vertically, and a fifth transmission bevel gear meshing with the ring bevel gear is fixedly connected to the lower end of the second transmission shaft. The upper end of the second transmission shaft extends upward to form a third transmission shaft. The cross-section of the third transmission shaft is square. A sixth bevel gear is fixedly connected to the side of the driven gear away from the first clamping roller. A seventh bevel gear meshing with the sixth bevel gear is rotatably connected inside the upper base. The seventh bevel gear is provided with a transmission hole adapted to the third transmission shaft. The third transmission shaft passes through the transmission hole and is slidably connected to the transmission hole.

[0044] With the above configuration, the drive device drives the first and second rotating rods to rotate synchronously via the transmission device. Specifically, when it is necessary to rotate the first and second rotating rods upward, loosen the first and second bolts. Then, the drive motor drives the seventh bevel gear to rotate via the drive gear, driven gear, and sixth bevel gear. The seventh bevel gear drives the damping sleeve to rotate via the third transmission shaft, second transmission shaft, fifth transmission bevel gear, and ring bevel gear. Damping oil, which can be silicone oil, is provided between the damping sleeve and the first transmission shaft. Under the action of damping, the damping sleeve drives the first transmission shaft to rotate. The first transmission shaft drives the first transmission bevel gear, third transmission bevel gear, and ring bevel gear to rotate. The gears and the first rotating sleeve drive the first rotating rod to rotate upwards. Meanwhile, the first transmission shaft drives the second rotating rod to rotate upwards via the second and fourth transmission bevel gears and the second rotating sleeve. During this process, the drive motor also drives the first clamping roller to rotate via the drive gear and the driven gear. When the roller of the first rotating rod abuts against the second stop surface, the roller of the second rotating rod abuts against the first stop surface. At this point, the drive motor is turned off, and the cable is pulled up from the cable well and clamped by the first and second clamping rollers. Because the third transmission shaft and the seventh bevel gear are slidably connected, during the upward movement of the upper base, the seventh bevel gear… The gear and the third drive shaft can always transmit power. Under the weight of the cable, the downward force exerted by the upper base on the roller increases, cutting the blade into the insulation layer. Then, the drive motor continues to run, driving the cable upward through the first clamping roller. On the other hand, because the downward force of the upper base on the roller increases, the damping sleeve cannot continue to drive the first drive shaft to rotate further. That is, the first and second rotating rods cannot rotate further upward. In other words, the first and second rotating rods remain supporting the upper base and will not lift the upper base further. After the cable head is connected to the electrical components, the first clamping roller and the third... The two clamping rollers separate the cable. At this time, the downward force of the upper base on the rollers decreases. After the drive motor runs in reverse, the drive motor drives the damping sleeve to rotate in the reverse direction. Under the action of damping, the damping sleeve drives the first transmission shaft to rotate in the reverse direction. The first transmission shaft drives the first rotating rod to rotate downward through the first transmission bevel gear, the third transmission bevel gear, and the first rotating sleeve. The first transmission shaft drives the second rotating rod to rotate downward through the second transmission bevel gear, the fourth transmission bevel gear, and the second rotating sleeve. The first rotating rod and the second rotating rod raise the lower base again. Then, tighten the first bolt and the second bolt to fix the first rotating sleeve and the second rotating sleeve. Then, the present application and the cable can be disconnected. Attached Figure Description

[0057] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0058] See Figures 1 to 12 A cable head splicing auxiliary device includes an upper base 11, on which a cable threading port 111 is provided. A first cable outlet 112 is provided on one side of the cable threading port 111. A first clamping roller 1111 and a second clamping roller 1112 are provided inside the cable threading port 111. The axis of the first clamping roller 1111 and the axis of the second clamping roller 1112 are parallel. The upper base 11 is provided with a driving device 12 for driving the first clamping roller 1111. A bracket 1113 is slidably connected inside the cable threading port 111. The second clamping roller 1112 is rotatably connected to the bracket 1113. The upper base 11 is provided with a sliding device 13 for driving the bracket 1113 to slide along the cable threading port 111.

[0059] With the above settings, the cable 21 can be raised and lowered. Specifically, the cable 21 is moved between the electrical cabinet 22 and the cable well 23, and then the cable 21 under the cable well 23 is manually pulled upwards and passed between the first clamping roller 1111 and the second clamping roller 1112. Under the action of the sliding device 13, the bracket 1113 moves along the cable insertion port 111 towards the first clamping roller 1111. The bracket 1113 drives the second clamping roller 1112 towards the first clamping roller 1111. Finally, the first clamping roller 1111 and the second clamping roller 1112 clamp the cable 21. At this time, the cable 21 is lifted and lowered. 1. The cable 21 is fixed between the first clamping roller 1111 and the second clamping roller 1112. The hand on the cable 21 can be released, and a cable head is made at the upper end of the cable 21. Then, the driving device 12 drives the first clamping roller 1111 to rotate around its axis. Under the action of friction, the cable 21 moves upward, while the second clamping roller 1112 rotates accordingly around its axis. The cable 21 passes upward through the cable port 24 on the lower side of the electrical cabinet 22 and approaches the electrical components inside the electrical cabinet 22. Then, the personnel connect the cable head and the electrical components. After the connection is completed, under the action of the sliding device 13, the bracket 1113 and the second clamping roller 1112 move away from the first clamping roller 1111. The first clamping roller 1111 and the second clamping roller 1112 separate the cable 21. Then, the cable 21 leaves the upper base 11 from the first outlet 112, thereby separating the cable 21 from the present application. Finally, the present application is taken out from between the electrical cabinet 22 and the cable well 23.

[0060] In one implementation, two sliding seats 113 are slidably connected to the upper side of the upper base 11, the wire threading port 111 is disposed between the sliding seats 113, and a blade 1131 is fixedly connected to the side of the sliding seat 113 near the wire threading port 111. The upper base 11 is provided with a control device 14 for controlling the sliding seats 113 to move closer to or away from the wire threading port 111.

[0061] With the above setup, the cable 21 can be stripped, facilitating the fabrication of the cable head. Specifically, when the cable 21 is clamped by the first clamping roller 1111 and the second clamping roller 1112, the upper end of the cable 21 is positioned between the two blades 1131. (See [reference]). Figure 6 The cable 21 includes a conductor 26 and an insulation layer 27 covering the outside of the conductor 26. Under the action of the control device 14, the two sliding seats 113 move closer to each other, driving the two blades 1131 to move closer to each other and cut into the cutting layer. The plane where the blades 1131 are located is perpendicular to the axis of the first clamping roller 1111. See [reference needed]. Figure 7 and Figure 8 Then, under the action of the drive device 12, the first clamping roller 1111 rotates and drives the cable 21 to move upward. As the cable 21 moves upward, the insulation layer 27 of the cable 21 is cut from top to bottom by the blade 1131. (See...) Figure 9 When the cutting length reaches a certain value, under the action of the control device 14, the two sliding seats 113 move away, causing the blade 1131 to separate. (See below) Figure 10 Under the action of the drive device 12, the first clamping roller 1111 continues to drive the cable 21 upward and through the cable opening 24. At this time, since the insulation layers 27 on both sides of the upper end of the cable 21 are cut, the insulation layers 27 can be peeled off like peeling a banana. Then, the peeled insulation layers 27 are cut off with scissors, thereby exposing the conductor 26, which is convenient for making the cable head. See [link to relevant documentation]. Figure 11 After the cable head and electrical components are connected, the first clamping roller 1111 and the second clamping roller 1112 separate and release the cable 21, and then the cable 21 leaves the present application from the first outlet 112.

[0062] In one implementation, a support plate 114 is provided on the side of the sliding seat 113 away from the wire insertion port 111. The support plate 114 is fixedly connected to the upper base 11. A first guide sleeve 1141 is fixedly connected to the support plate 114. A first guide rod 1142 is slidably connected inside the first guide sleeve 1141. The first guide rod 1142 is fixedly connected to the sliding seat 113.

[0063] With the above settings, the sliding seat 113 slides more stably along the upper base 11. Specifically, the axis of the first guide sleeve 1141 is perpendicular to the axis of the first clamping roller 1111, the first guide rod 1142 is coaxial with the first guide sleeve 1141, and the axis of the first guide rod 1142 is parallel to the upper side of the upper base 11.

[0064] In one implementation, the control device 14 includes a first screw 141 that passes through and is threadedly connected to the slide seat 113, the axis of the first screw 141 being parallel to the axis of the first guide rod 1142.

[0065] With the above settings, when it is necessary to drive the sliding seat 113, the first screw 141 is rotated, and the first screw 141 and the sliding seat 113 rotate relative to each other. When the first screw 141 and the sliding seat 113 are threadedly connected, the sliding seat 113 moves along the axial direction of the first screw 141.

[0066] In one implementation, a first bevel gear 142 and a second bevel gear 143 are rotatably connected inside the support plate 114. The first bevel gear 142 is fixedly connected to the first screw 141, and the first bevel gear 142 and the second bevel gear 143 mesh. A drive screw 144 is fixedly connected to the second bevel gear 143, and one end of the drive screw 144 is located on the side of the support plate 114.

[0067] With the above configuration, the first screw 141 can be rotated easily. Specifically, the end of the drive screw 144 away from the second bevel gear 143 is located on the same side of the upper base 11, which makes it convenient for personnel on one side of the upper base 11 to control the movement of the two sliding seats 113 respectively. Specifically, the personnel use an electric screwdriver to rotate the drive screw 144, and the drive screw 144 drives the first screw 141 to rotate through the second bevel gear 143 and the first bevel gear 142.

[0068] In one implementation, a driven gear 11111 is fixedly connected to one end of the first clamping roller 1111. The driving device 12 includes a drive motor 121 disposed on one side of the upper base 11. The drive motor 121 is connected to a drive gear 122. The drive gear 122 meshes with the driven gear 11111. The radius of the drive gear 122 is smaller than the radius of the driven gear 11111.

[0069] With the above settings, the first wire clamping roller 1111 can be rotated stably. Specifically, the drive motor 121 drives the first wire clamping roller 1111 to rotate through the drive gear 122 and the driven gear 11111. When the radius of the drive gear 122 is smaller than the radius of the driven gear 11111, the power of the drive motor 121 can be reduced. In addition, the drive motor 121 can be set as a motor with a self-locking function to prevent the cable 21 from slipping back.

[0070] In one implementation, the radius of the first clamping roller 1111 gradually increases from the middle to both ends, and the radius of the second clamping roller 1112 gradually increases from the middle to both ends.

[0071] With the above settings, the cable 21 can be prevented from shifting laterally during the ascent. Specifically, when the cable 21 is clamped by the first clamping roller 1111 and the second clamping roller 1112, the cable 21 is basically located in the middle of the first clamping roller 1111 and the second clamping roller 1112. Since the gap between the first clamping roller 1111 and the second clamping roller 1112 gradually decreases from the middle to both ends, the cable 21 will not shift to both ends.

[0072] In one implementation, the support 1113 is U-shaped with its opening facing the first clamping roller 1111. The second clamping roller 1112 is rotatably connected between the two ends of the support 1113. The upper base 11 is provided with a threaded groove 115. The sliding device 13 includes a second screw 131 rotatably connected to the support 1113. The axis of the second screw 131 is perpendicular to the axis of the first clamping roller 1111. The end of the second screw 131 away from the support 1113 is threaded into the threaded groove 1115. A drive rod 132 is fixedly connected inside the upper base 11. The cross-section of the drive rod 132 is square. A drive wheel 133 is sleeved on the drive rod 132. The drive wheel 133 is provided with a drive groove 134 that is adapted to the drive rod 132. The drive rod 132 passes through the drive groove 134 and is slidably connected to the drive groove 134. The drive wheel 133 is rotatably connected to one side of the upper base 11. A fixing bolt 135 is threadedly connected to the drive wheel 133. The fixing bolt 135 abuts against the upper base 11.

[0073] With the above configuration, when the support bracket 1113 needs to be driven, the drive wheel 133 is rotated. The drive wheel 133 drives the second screw 131 to rotate via the drive rod 132. When the second screw 131 and the threaded groove 115 rotate relative to each other, the second screw 131 moves along its axial direction. Since the second screw 131 and the support bracket 1113 are rotatably connected, the second screw 131 drives the support bracket 1113 to move closer to or away from the first clamping roller 1111. The second screw 131 and the drive rod 132 are integrally formed, and the cross-section of the drive rod 132 is square, thereby realizing the transmission between the drive rod 132 and the drive wheel 133. The drive rod 132 and the drive groove 134 are slidably connected, so that when the second screw 131 moves along the axis of the second screw 131, the drive rod 132 also moves along the axis of the second screw 131. The drive rod 132 and the drive groove 134 slide relative to each other. When the fixing bolt 135 is tightened, the fixing bolt 135 abuts against the upper base 11. Under the action of friction, the drive wheel 133 is prevented from rotating, thereby preventing the second screw 131 from rotating, and thus preventing the distance between the first wire clamping roller 1111 and the second wire clamping roller 1112 from changing. When the fixing bolt 135 is loosened, the drive wheel 133 can rotate freely.

[0074] As one implementation, a roller 15 is provided below the upper base 11.

[0075] The above settings facilitate the relocation of this application.

[0076] In one implementation, a lower base 16 is provided below the upper base 11, and the lower base 16 and the upper base 11 are connected by a telescopic rod 161 extending vertically. The driving device 12 is also used to drive the upper base 11 to rise and fall.

[0077] The height of this application can be adjusted through the above settings, thereby further facilitating its movement. Specifically, initially, the distance between the upper base 11 and the lower base 16 is small, resulting in a smaller height for this application, making it easier to place it between the cable port 24 and the cable well 23 of the electrical cabinet 22. After the application is placed in position, under the action of the drive device 12, the upper base 11 moves upward and approaches the cable port 24. As the upper base 11 moves upward, the gap between the upper base 11 and the lower base 16 increases, making it easier for personnel to pull up the cable 21 in the cable well 23 through the gap between the upper base 11 and the lower base 16. The drive device 12 is also used to drive the lifting and lowering of the upper base 11, thereby increasing the compactness of the structure of this application.

[0078] In one implementation, the telescopic rod 161 includes a second guide sleeve 1611 whose lower end is fixedly connected to the lower base 16, a second guide rod 1612 which is slidably connected inside the second guide sleeve 1611, and the upper end of the second guide rod 1612 which is fixedly connected to the upper base 11.

[0079] The above settings make the lifting and lowering of the upper base 11 more stable.

[0080] In one implementation, a limiting groove 1613 is provided on the inner side of the second guide sleeve 1611, and a limiting protrusion 1614 is fixedly connected to the second guide rod 1612, with the limiting protrusion 1614 slidably connected within the limiting groove 1613.

[0081] The above-mentioned arrangement prevents the second guide rod 1612 from being pulled upward out of the second guide sleeve 1611.

[0082] In one implementation, the lower base 16 includes two parallel support beams 162. The extending direction of the support beams 162 is perpendicular to the axis of the first clamping roller 1111. The support beams 162 are fixedly connected by a first rotating shaft 163 and a second rotating shaft 164. The first rotating shaft 163 and the second rotating shaft 164 are parallel and located at both ends of the support beams 162. One of the support beams 162 is provided with a second cable outlet 1621, which divides the corresponding support beam 162 into two sub-beams 1622. A first rotating sleeve 1631 is fitted onto the first rotating shaft 163. The first rotating sleeve 1631 is provided with a function to fix the first rotating sleeve 1631 to the first rotating shaft 163. The first fixing device 1632 is provided on the second rotating shaft 164, and the second rotating shaft 164 is sleeved with a second rotating sleeve 1641. The second rotating sleeve 1641 is provided with a second fixing device 1642 for fixing the second rotating sleeve 1641 on the second rotating shaft 164. The two ends of the first rotating sleeve 1631 are fixedly connected to a first rotating rod 1633, and the two ends of the second rotating sleeve 1641 are fixedly connected to a second rotating rod 1643. The end of the first rotating rod 1633 away from the first rotating sleeve 1631 extends downward at an angle toward the side of the second rotating sleeve 1641 and is rotatably connected to the roller 15. The end of the second rotating rod 1643 away from the second rotating sleeve 1641 extends downward at an angle toward the side of the first rotating sleeve 1631 and is rotatably connected to the roller 15.

[0083] With the above configuration, the roller 15 can be positioned on the lower side of the base 16, thereby facilitating the movement of this application.

[0084] In one implementation, the first fixing device 1632 includes a first bolt 16321 threadedly connected to the first rotating sleeve 1631, and the first rotating shaft 163 is provided with a first threaded hole 1634, with one end of the first bolt 16321 inserted into the first threaded hole 1634. The second fixing device 1642 includes a second bolt 16421 threadedly connected to the second rotating sleeve 1641, and the second rotating shaft 164 is provided with a second threaded hole 1644, with one end of the second bolt 16421 inserted into the second threaded hole 1644.

[0085] Through the above settings, the first rotating sleeve 1631 and the first rotating shaft 163 are fixed, as are the second rotating sleeve 1641 and the second rotating shaft 164. When the first bolt 16321 is loosened so that the first bolt 16321 and the first threaded hole 1634 are disengaged, the first rotating sleeve 1631 and the first rotating shaft 163 can rotate relative to each other. When the second bolt 16421 is loosened so that the second bolt 16421 and the second threaded hole 1644 are disengaged, the second rotating sleeve 1641 and the second rotating shaft 164 can rotate relative to each other.

[0086] In one implementation, the driving device 12 is connected to the first rotating sleeve 1631 via the transmission device 17 and is used to drive the first rotating sleeve 1631 to rotate; the driving device 12 is connected to the second rotating sleeve 1641 via the transmission device 17 and is used to drive the second rotating sleeve 1641 to rotate.

[0087] The driving device 12 drives the first rotating rod 1633 and the second rotating rod 1643 to rotate upward through the transmission device 17, thereby pushing the upper base 11 to move upward.

[0088] With the above configuration, the first rotating rod 1633 and the second rotating rod 1643 can rotate upward and push the upper base 11 to move upward. Specifically, the length of the first rotating rod 1633 is less than the shortest distance between the first rotating sleeve 1631 and the second rotating sleeve 1641. Therefore, when the first rotating rod 1633 rotates upward, the first rotating rod 1633 and the corresponding roller 15 will not interfere with the second rotating sleeve 1641. The length of the second rotating rod 1643 is less than the shortest distance between the first rotating sleeve 1631 and the second rotating sleeve 1641. Therefore, when the second rotating rod 1643 rotates upward, the second rotating rod 1643 and the corresponding roller 15 will not interfere with the first rotating sleeve 1631.

[0089] After the device moves to the space between the cable port 24 and the cable well 23, the first bolt 16321 and the second bolt 16421 are loosened. Then, under the action of the drive device 12, the first rotating rod 1633 and the second rotating rod 1643 rotate upward and raise the upper base 11. See [link to relevant documentation]. Figure 5When the first rotating rod 1633 and the second rotating rod 1643 raise the upper base 11, the limiting protrusion 1614 approaches the upper end of the limiting groove 1613, the roller 15 abuts against the lower side of the upper base 11, and the lower side of the lower base 16 abuts against the ground 25, thereby preventing the present application from shifting. Then the cable 21 extends out from the cable well 23 and passes between the second rotating rods 1643. At this time, the upper end of the cable 21 is located between the first clamping roller 1111 and the second clamping roller 1112. Under the action of the sliding device 13, the first clamping roller 1111 and the second clamping roller 1112 approach and clamp the cable 21. When the cable 21 is clamped by the first clamping roller 1111 and the second clamping roller 1112, the upper end of the cable 21 is located between the two blades 1131. See Figure 6 The cable 21 includes a conductor 26 and an insulation layer 27 covering the outside of the conductor 26. Under the action of the control device 14, the two sliding seats 113 move closer to each other, driving the two blades 1131 to move closer to each other and cut into the cutting layer. The plane where the blades 1131 are located is perpendicular to the axis of the first clamping roller 1111. See [reference needed]. Figure 7 and Figure 8 Then, under the action of the drive device 12, the first clamping roller 1111 rotates and drives the cable 21 to move upward. As the cable 21 moves upward, the insulation layer 27 of the cable 21 is cut from top to bottom by the blade 1131. (See...) Figure 9 When the cutting length reaches a certain value, under the action of the control device 14, the two sliding seats 113 move away, causing the blade 1131 to separate. (See below) Figure 10 Under the action of the drive device 12, the first clamping roller 1111 continues to drive the cable 21 upward and through the cable opening 24. At this time, since the insulation layers 27 on both sides of the upper end of the cable 21 are cut, the insulation layers 27 can be peeled off like peeling a banana. Then, the peeled insulation layers 27 are cut off with scissors, thereby exposing the conductor 26, which is convenient for making the cable head. See [link to relevant documentation]. Figure 11 After the cable head and electrical components are connected, the first clamping roller 1111 and the second clamping roller 1112 separate and loosen the cable 21.

[0090] When it is necessary to disconnect cable 21 from this application, this application returns to its initial state, i.e., see [link to relevant documentation]. Figure 2Under the action of the drive device 12, the first rotating sleeve 1631 and the second rotating sleeve 1641 rotate, driving the first rotating rod 1633 and the second rotating rod 1643 to rotate downward and raise the lower base 16. When the first bolt 16321 and the first threaded hole 1634 are aligned, the first bolt 16321 is tightened to fix the first rotating sleeve 1631 and the first rotating shaft 163. When the second bolt 16421 and the second threaded hole 1644 are aligned, the second bolt 16421 is tightened to fix the second rotating sleeve 1641 and the second rotating shaft 164. A first positioning block can be provided on the side of the first rotating sleeve 1631 away from the second rotating sleeve 1641. 41. The first positioning block 41 and the support beam 162 are fixedly connected. The second positioning block 42 is fixedly connected to the outside of the first rotating sleeve 1631. When the upper side of the second positioning block 42 abuts against the first positioning block 41, the first threaded hole 1634 and the first bolt 16321 are aligned. A third positioning block 43 can be set on the side of the second rotating sleeve 1641 away from the first rotating sleeve 1631. The third positioning block 43 and the support beam 162 are fixedly connected. The fourth positioning block 44 is fixedly connected to the outside of the second rotating sleeve 1641. When the upper sides of the third positioning block 43 and the fourth positioning block 44 abut against each other, the second bolt 16421 and the second threaded hole 1644 are aligned. When the lower base 16 is raised by the first rotating rod 1633 and the second rotating rod 1643, the lower base 16 disengages from the ground 25, the roller 15 abuts against the ground 25, the telescopic rod 161 shortens, and the limiting protrusion 1614 slides downward along the limiting groove 1613 and approaches the lower end of the limiting groove 1613. At this time, a first clearance opening 31 is formed between the second rotating rod 1643 and the first rotating sleeve 1631, a first clearance space 32 is formed between the first rotating rod 1633 and the second rotating rod 1643, a second clearance opening 33 is formed between the second rotating sleeve 1641 and the first rotating rod 1633, and a second clearance space 34 is formed between the first rotating rod 1633 and the dividing beam 1622. The cable 21 disengages from the first outlet 112 and the upper base 11. See [reference needed] Figure 12 The cable 21 is separated from the first clearance port 31, the second clearance space 34, the second clearance port 33, the second clearance space 34, the second outlet port 1621 and the lower base 16 in succession, thus completing the separation of the cable 21 from this application.

[0091] In one implementation, a first limiting block 116 and a second limiting block 117 are fixedly connected to the lower side of the upper base 11. The first limiting block 116 is located on the side of the first wire clamping roller 1111 away from the second wire clamping roller 1112, and the second limiting block 117 is located on the side of the second wire clamping roller 1112 away from the first wire clamping roller 1111. The first limiting block 116 is provided with a first stop surface 1161 and a first guide surface 1162 for guiding the roller 15 on the second rotating rod 1643 to the first stop surface 1161. The first stop surface 1161 is located at the end of the first limiting block 116 near the wire threading opening 111, and the first guide surface 1162 is located at the first stop surface 1161. On the side away from the threading opening 111, the first guide surface 1162 is inclined downward at one end near the first stop surface 1161 and connected to the lower end of the first stop surface 1161. The second limiting block 117 is provided with a second stop surface 1171 and a second guide surface 1172 for guiding the roller 15 on the first rotating rod 1633 to the second stop surface 1171. The second stop surface 1171 is located at one end of the second limiting block 117 near the threading opening 111. The second guide surface 1172 is located on the side of the second stop surface 1171 away from the threading opening 111. The end of the second guide surface 1172 near the threading opening 111 is inclined downward and connected to the lower end of the second stop surface 1171.

[0092] The first stop surface 1161 is an arc surface. When the roller 15 of the second rotating rod 1643 abuts against the first stop surface 1161, the axis of the first stop surface 1161 coincides with the axis of the second rotating shaft 164.

[0093] The second stop surface 1171 is an arc surface. When the roller 15 of the first rotating rod 1633 abuts against the second stop surface 1171, the axis of the second stop surface 1171 coincides with the axis of the first rotating shaft 163.

[0094] With the above configuration, the first rotating rod 1633 and the second rotating rod 1643 can provide stable support for the upper base 11. For details, please refer to [link / reference]. Figure 5During the upward rotation of the first rotating rod 1633, the roller 15 of the first rotating rod 1633 abuts against and lifts the upper base 11. As the first rotating rod 1633 continues to rotate upward, the roller 15 passes the second guide surface 1172 and moves to the second stop surface 1171. Under the action of gravity, the upper base 11 moves downward and abuts against the roller 15. At this time, the roller 15 of the first rotating rod 1633 abuts against the second stop surface 1171. Similarly, during the upward rotation of the second rotating rod 1643, the roller 15 of the second rotating rod 1643 abuts against and lifts the upper base 11. As the second rotating rod 1643 continues to rotate upward, the roller 15 passes the first guide surface 1162 and moves to the first stop surface 1161. Under the action of gravity, the upper base 11 moves downward and abuts against the roller 15. At this time, under the weight of the upper base 11 and the cable 21, the roller 15 of the first rotating rod 1633 is stuck between the second stop surface 1171 and the upper base 11, and the roller 15 of the second rotating rod 1643 is stuck between the first stop surface 1161 and the upper base 11. The first rotating rod 1633 and the second rotating rod 1643 provide good support for the upper base 11.

[0095] In one implementation, the transmission device 17 includes a first transmission shaft 171, one end of which is fixedly connected to a first transmission bevel gear 1711, and the other end of which is fixedly connected to a second transmission bevel gear 1712. One end of a first rotating sleeve 1631 is fixedly connected to a third transmission bevel gear 172, and one end of a second rotating sleeve 1641 is fixedly connected to a fourth transmission bevel gear 173. The first transmission bevel gear 1711 and the third transmission bevel gear 172 mesh, and the second transmission bevel gear 1712 and the fourth transmission bevel gear 173 mesh. A damping sleeve 1713 is fitted onto the first transmission shaft 171, and damping oil is disposed between the damping sleeve 1713 and the first transmission shaft 171. Two annular protrusions 1714 are fixedly connected to the first transmission shaft 171, and the damping sleeve 1713 is disposed between the annular protrusions 1714. The outer side of the damping sleeve 1713 is fixed. The transmission device 17, connected to an annular bevel gear 1715, also includes a bushing 174 fixedly connected to the support beam 162 and a second transmission shaft 175 passing through the bushing 174. The second transmission shaft 175 extends vertically, and a fifth transmission bevel gear 1751 meshing with the annular bevel gear 1715 is fixedly connected to the lower end of the second transmission shaft 175. The upper end of the second transmission shaft 175 extends upward to form a third transmission shaft 1752, which has a square cross-section. A sixth bevel gear 176 is fixedly connected to the side of the driven gear 11111 away from the first clamping roller 1111. A seventh bevel gear 177 meshing with the sixth bevel gear 176 is rotatably connected inside the upper base 11. The seventh bevel gear 177 has a transmission hole 1771 adapted to the third transmission shaft 1752. The third transmission shaft 1752 passes through the transmission hole 1771 and is slidably connected to the transmission hole 1771.

[0096] With the above configuration, the drive device 12 drives the first rotating rod 1633 and the second rotating rod 1643 to rotate synchronously via the transmission device 17. For details, see [link to details]. Figure 5When the first rotating rod 1633 and the second rotating rod 1643 need to be rotated upwards, the first bolt 16321 and the second bolt 16421 are loosened. Then, the drive motor 121 drives the seventh bevel gear 177 to rotate through the drive gear 122, the driven gear 11111, and the sixth bevel gear 176. The seventh bevel gear 177 drives the damping sleeve 1713 to rotate through the third transmission shaft 1752, the second transmission shaft 175, the fifth transmission bevel gear 1751, and the ring bevel gear 1715. Damping oil is provided between the damping sleeve 1713 and the first transmission shaft 171. The damping oil can be silicone oil. Under the action of damping, the damping sleeve 1713 drives the first transmission shaft 171 to rotate. The first transmission shaft 171 drives the first rotating rod 1633 to rotate upwards through the first transmission bevel gear 1711, the third transmission bevel gear 172, and the first rotating sleeve 1631. On the other hand, the first rotating rod 1633... A drive shaft 171 drives a second rotating rod 1643 to rotate upwards via a second drive bevel gear 1712, a fourth drive bevel gear 173, and a second rotating sleeve 1641. During this process, a drive motor 121 also drives a first clamping roller 1111 to rotate via a drive gear 122 and a driven gear 11111. When the roller 15 of the first rotating rod 1643 abuts against the second stop surface 1171, the roller 15 of the second rotating rod 1643 abuts against the first stop surface 1161. At this point, the drive motor 121 is turned off, and the cable 21 is pulled up from the cable well 23 and clamped by the first clamping roller 1111 and the second clamping roller 1112. Because the third drive shaft 1752 and the seventh bevel gear 177 are slidably connected, the seventh bevel gear 177 and the third drive shaft 1752 can always transmit power during the upward movement of the upper base 11. (See also...) Figure 6 Under the weight of cable 21, the downward force exerted by the upper base 11 on the roller 15 increases, causing the blade 1131 to cut into the insulation layer 27. (See attached image) Figure 7 Then, the drive motor 121 continues to run, driving the cable 21 upward through the first clamping roller 1111. On the other hand, because the downward force of the upper base 11 on the roller 15 increases, the damping sleeve 1713 cannot continue to drive the first drive shaft 171 to rotate further. That is, the first rotating rod 1633 and the second rotating rod 1643 cannot rotate further upward. In other words, the first rotating rod 1633 and the second rotating rod 1643 remain supporting the upper base 11 and will not raise the upper base 11 further. See [link to relevant documentation]. Figure 9 After the cable head is connected to the electrical components, see [link / reference]. Figure 11The first clamping roller 1111 and the second clamping roller 1112 separate the cable 21. At this time, the downward force of the upper base 11 on the roller 15 decreases. After the drive motor 121 runs in the reverse direction, the drive motor 121 drives the damping sleeve 1713 to rotate in the reverse direction. Under the action of damping, the damping sleeve 1713 drives the first transmission shaft 171 to rotate in the reverse direction. The first transmission shaft 171 drives the first rotating rod 1633 to rotate downward through the first transmission bevel gear 1711, the third transmission bevel gear 172, and the first rotating sleeve 1631. The first transmission shaft 171 drives the second rotating rod 1643 to rotate downward through the second transmission bevel gear 1712, the fourth transmission bevel gear 173, and the second rotating sleeve 1641.

Figure 2 The first rotating rod 1633 and the second rotating rod 1643 raise the lower base 16 again, and then tighten the first bolt 16321 and the second bolt 16421 to fix the first rotating sleeve 1631 and the second rotating sleeve 1641. Then, this application and the cable 21 can be disconnected.
