Description

Technical Field

[0001] This invention relates to the technical field of wrapping insulating tape from a roll of material onto a cable splice, and in particular to an efficient apparatus and method for wrapping insulating tape onto a cable splice. Background Technology

[0002] Cables are used to transmit signals and are laid underground or suspended in the air. During actual cable laying, one cable is usually spliced ​​with another to obtain a suitable cable for the installation. The procedure for workers to splice two cables together is as follows: S1. The worker peels off the insulation layer at the free end of cable A1 to expose conductor 2 of cable A1. Figure 1 As shown; S2, strip the insulation layer from the free end of cable B3 to expose conductor 2 of cable B3, as shown. Figure 2 As shown; S3, fuse conductor 2 of cable A1 and conductor 2 of cable B3 together to form a cable fusion joint 4, as shown. Figure 3 As shown; S4, the worker uses a wrapping machine to wrap multiple turns of insulating tape 5 around the cable fusion joint 4 along its length, as shown. Figure 4 As shown, the insulating tape 5 covers the cable fusion joint 4 so that the cables A1 and B3 connected together can continue to be used.

[0003] In step S4, the structure of the winding machine used is as follows: Figures 5-6 As shown, the winding machine includes a movable plate 12 that can move back and forth, a gear ring 16 rotatably mounted on one end face of the movable plate 12, a mounting rod 20 fixed on one end face of the gear ring 16, a drive motor 18 fixed on the movable plate 12, and a gear 19 mounted on the output shaft of the drive motor 18, which meshes with the gear ring 16.

[0004] The method by which the worker uses the wrapping machine to wrap multiple turns of insulating tape 5 around the cable fusion splice 4 is as follows: Sa, the worker passes the fused cable A1 from left to right through the center hole 17 of the toothed ring 16, ensuring that the cable fusion joint 4 located between cable A1 and cable B is within the center hole 17 of the toothed ring 16. Figures 7-8 As shown, both cable A1 and cable B3 are secured at the same time; Sb, The worker takes out a roll of material [the roll includes a sleeve 6, with multiple turns of insulating tape 5 wound around the sleeve 6, the structure of the roll is as follows] Figures 9-10 As shown in the image, the worker then places the sleeve 6 of the coiled material onto the mounting rod 20 of the winding machine, as shown. Figures 7-8 As shown; Sc. The worker pulls out the first end of the insulating tape 5 wrapped around the sleeve 6, and then fixes the first end of the insulating tape 5 to the outer surface of the first section of the cable splice 4, as shown. Figures 11-12 As shown; Sd, the worker turns on the drive motor 18, the drive motor 18 drives the gear 19 to rotate, the gear 19 drives the gear ring 16 to rotate around its own axis, the gear ring 16 drives the mounting rod 20 to rotate around the center line of the gear ring 16, the mounting rod 20 drives the sleeve 6 of the coil to move synchronously, at this time, the insulating tape 5 wrapped on the sleeve 6 begins to be released and begins to be wrapped around the cable fusion splice 4. Simultaneously, the worker drives the movable plate 12 to reciprocate left and right, which in turn drives the toothed ring 16 to reciprocate left and right, thereby causing the coiled material to reciprocate left and right. The insulating tape 5 released from the sleeve 6 is gradually wound around the cable fusion splice 4 along its length. When all the insulating tape on the sleeve 6 has been unwound and wound around the cable fusion splice 4, multiple turns of insulating tape 5 can be wound around a single cable fusion splice 4. The structure after winding is as follows: Figure 4 As shown; Se, after the cable fusion splice 4 is wrapped with a layer of insulating tape, the worker turns off the drive motor 18, and then the worker removes the cable fusion splice 4, cable A1 and cable B3 wrapped with insulating tape 5. Sf, the worker repeats steps Sa~Se in this way, so that insulation tape 5 can be continuously wrapped around multiple cable fusion joints 4.

[0005] However, although this type of wrapping machine can wrap insulating tape 5 around the cable fusion splice 4, it still has the following technical defects: I. In step Sb, when the worker manually puts the sleeve 6 of the coiled material onto the installation rod 20, the sweat on the worker's hands can easily get onto the insulating tape 5 on the sleeve 6. This can cause the insulating tape 5 wrapped around the outside of the cable fusion splice 4 to be punctured during the withstand voltage test of the cable fusion splice 4, which in turn makes the connected cables A1 and B3 unusable, thereby reducing the quality of the insulating tape 5 wrapped on the cable fusion splice 4.

[0006] II. In step Sd, the insulating tape 5 released from the sleeve 6 was not wrapped around the cable fusion splice 4 in a taut state, resulting in the cable fusion splice 4 not being securely wrapped. Consequently, when the withstand voltage test was performed on the cable fusion splice 4, the insulating tape 5 wrapped around the outside of the cable fusion splice 4 was punctured, causing the connected cables A1 and B3 to become unusable, thereby reducing the quality of the insulating tape 5 wrapped around the cable fusion splice 4.

[0007] III. The number of cable fusion splices 4 to be wrapped with insulating tape is large every day, which means that the roll of material needs to be put on the installation rod 20 multiple times in order to wrap the insulating tape 5 on multiple cable fusion splices 4. The entire operation of installing the roll of material is done manually, which undoubtedly increases the wrapping time and reduces the efficiency of wrapping the insulating tape 5 on the cable fusion splices 4.

[0008] Therefore, there is an urgent need for a device and method that can greatly improve the quality of wrapping insulating tape on cable splices and greatly improve the efficiency of wrapping insulating tape on cable splices. Summary of the Invention

A tensioning mechanism for tightening the insulating tape is provided on the left end face of the gear ring. The tensioning mechanism is located below the installation rod. The tensioning mechanism includes a fixed rod fixedly provided on the left end face of the gear ring. Two downwardly extending round rods are fixedly provided on the fixed rod. A pressure strip located below the fixed rod is slidably installed between the two round rods. A spring is sleeved on both round rods. The upper end of the spring is fixedly provided on the fixed rod, and the other end is fixedly provided on the top surface of the pressure strip. The left vertical plate is provided with an upper mounting mechanism for automatically mounting the sleeve of the coil material onto the mounting rod. The upper mounting mechanism includes a feed cylinder fixed to the right end face of the left vertical plate. The piston rod of the feed cylinder passes through the left vertical plate to the left, and a moving plate is fixed to the extended end. A smooth rod is fixed to the right end face of the moving plate. The smooth rod and the mounting rod are on the same horizontal straight line. Multiple coil materials are arranged on the smooth rod along its length direction, and the sleeve of each coil material is mounted on the smooth rod. A horizontal cylinder is fixed on the left end face of the movable plate, located above the light rod. The piston rod of the horizontal cylinder passes through the movable plate, and a bracket is fixed on the extended end. A vertical cylinder is fixed on the top surface of the bracket. The piston rod of the vertical cylinder passes downward through the bracket, and a clamping cylinder is fixed on the extended end. The clamping cylinder's chuck faces the rightmost sleeve of the coiled material.

[0011] Four guide pillars are fixed between the left and right upright plates, and the guide pillars are distributed at the four corners of the right upright plate.

[0012] The right end face of the movable plate is fixed with guide seats corresponding to the four guide columns. The four guide seats are slidably sleeved on the four guide columns.

[0013] Four limiting wheels are mounted on the left end face of the movable plate and rotate around the circumference of the square groove. The four limiting wheels are evenly distributed, and the gear ring is rotatably mounted outside the circle formed by the four limiting wheels.

[0014] The cross-sectional diameter of the optical rod is equal to the inner diameter of the sleeve of the coil.

[0015] A cylinder is fixed to the outer end face of both the left and right vertical plates, and the inner hole of the cylinder penetrates the corresponding vertical plate; locking screws are threaded to the top and bottom walls of the cylinder, and a pressure head is fixed to the extension end of the locking screw.

[0016] The left vertical plate has a through groove that is opposite to the left and right of the clamping cylinder.

[0017] The device also includes a controller, which is electrically connected to the feed cylinder, horizontal cylinder, vertical cylinder, clamping cylinder, linear cylinder and drive motor via signal lines.

[0018] A method for efficiently wrapping insulating tape around a cable splice includes the following steps: S1. The worker passes cable A sequentially from right to left through the right cylinder, right vertical plate, square groove in the movable plate, center hole of the toothed ring, right vertical plate, and left cylinder, ensuring that cable A is in the left cylinder and cable B is in the right cylinder, while ensuring that cable B is in the center hole of the toothed ring. S2. The worker tightens the locking screw on the left cylinder, which drives the pressure head to move towards cable A until cable A is clamped and fixed between the two pressure heads; the worker tightens the locking screw on the right cylinder, which drives the pressure head to move towards cable B until cable B is clamped and fixed between the two pressure heads, thus fixing the cable splice located between cable A and cable B. S3. The specific operation method for mounting the coiled material on the installation rod is as follows: S31. Control the moving part of the linear cylinder to move to the left. The moving part drives the movable plate to move to the left along the guide column. The movable plate drives the gear ring, the tensioning mechanism and the mounting rod to move to the left synchronously. When the moving part moves to the set distance, the controller controls the linear cylinder to close. At this time, the center hole of the gear ring is just fitted on the outside of the cable A, and the tensioning mechanism is just above the cable A. S32. Control the piston rod of the feed cylinder of the upper assembly mechanism to retract to the right. The piston rod drives the moving plate to move to the right. The moving plate drives the smooth rod and the horizontal cylinder to move to the right synchronously. The smooth rod drives each coil of material on it to move to the right synchronously. When the piston rod of the feed cylinder retracts to the set stroke, the controller controls the feed cylinder to close. At this time, the right end of the smooth rod is just close to the mounting rod located on the gear ring. S33. The piston rod of the vertical cylinder of the upper device controlled by the worker extends downward, the piston rod drives the clamping cylinder to move downward, the clamping cylinder drives the chuck to move downward, and the chuck moves towards the sleeve of the first coil of material located on the smooth rod. When the piston rod of the vertical cylinder is fully extended, the chuck is just placed on the outside of the sleeve of the first coil of material. S34. Control the start of the clamping cylinder, the clamping cylinder drives the chuck to close, and the chuck clamps and fixes the first roll of material in place; S35. The piston rod of the horizontal cylinder of the upper assembly mechanism extends to the right, the piston rod drives the bracket to move to the right, the bracket drives the vertical cylinder and the clamping cylinder to move to the right in sync, and then drives the clamped sleeve to move to the right. The sleeve drives the insulating tape wound on it to move to the right in sync. When the piston rod of the horizontal cylinder extends to the set stroke, the sleeve of the first roll of material is just fitted onto the mounting rod. S36. Control the clamping cylinder to close, the clamping cylinder drives the chuck to open, the chuck releases the sleeve of the first coil, that is, the chuck no longer clamps the sleeve; S37. Control the piston rod of the vertical cylinder to retract upwards, the piston rod drives the clamping cylinder to move upwards, and in turn drives the chuck to move upwards; control the piston rod of the horizontal cylinder to retract to the left, the piston rod drives the bracket to move to the left, the bracket drives the vertical cylinder and the clamping cylinder to move to the left synchronously, when the piston rod of the horizontal cylinder retracts to the set stroke, the controller controls the horizontal cylinder to close, at this time, the chuck just moves to the top of the sleeve of the second roll; control the piston rod of the feed cylinder to extend to the left, the piston rod drives the moving plate to move to the left, the moving plate drives the guide rod to move to the left, the guide rod drives each roll of material on it to move to the left synchronously, thus finally realizing the mounting of the roll of material on the mounting rod; S4. Wrap the insulating tape from the coil around the cable fusion splice. The specific operation method is as follows: S41. Control the moving part of the linear cylinder to move to the right. The moving part drives the movable plate to move to the right along the guide column. The movable plate drives the gear ring, the tensioning mechanism and the mounting rod to move to the right synchronously. When the moving part moves to the set distance, the controller controls the linear cylinder to close. At this time, the tensioning mechanism just moves to the top of the left end of the cable fusion splice. S42. The worker pulls out the first end of the insulating tape wrapped around the sleeve, then passes the first end of the insulating tape through the area enclosed by the pressure bar and the fixing rod of the tensioning mechanism, and finally fixes the insulating tape to the outer surface of the first section of the cable splice. S43. The worker turns on the drive motor, which drives the gear to rotate. The gear drives the gear ring to rotate around its own axis. The gear ring drives the tensioning mechanism and the mounting rod to rotate around the center line of the gear ring. Under centrifugal force, the pressure bar on the tensioning mechanism moves along the round rod toward the fixed rod, thereby clamping the insulating tape between the fixed rod and the pressure bar. At the same time, the mounting rod drives the sleeve of the roll of material mounted on it to move synchronously. At this time, the insulating tape wrapped on the sleeve begins to be released and begins to wrap around the cable fusion splice. S44. The worker controls the moving part of the linear cylinder to move to the right. The moving part drives the movable plate to move to the right. The movable plate drives the toothed ring, the winding material and the tensioning mechanism to move to the right in sync. When the tensioning mechanism moves to the right end of the cable fusion splice, it can just wrap a circle of insulating tape around the cable fusion splice. S45. Control the moving part of the linear cylinder to make reciprocating left and right movements. The moving part drives the movable plate to make reciprocating left and right movements. The movable plate drives the gear ring to make reciprocating left and right movements, which in turn drives the coil to make reciprocating left and right movements. During the reciprocating movement, the insulating tape released from the sleeve is gradually wrapped around the cable fusion joint along the length of the cable fusion joint. When all the insulating tape on the sleeve is unwound and wrapped around the cable fusion joint, multiple turns of insulating tape can be wrapped around a cable fusion joint, thus finally realizing the wrapping of the insulating tape on the coil onto the cable fusion joint. S5. After the cable splice is wrapped, the worker turns off the drive motor, then loosens the locking screw, and finally removes the cable splice wrapped with insulating tape, cable A and cable B. S6. Workers can repeat steps S1 to S5 to continuously wrap insulating tape around multiple cable fusion joints.

[0019] The present invention has the following advantages: it greatly improves the quality of wrapping insulating tape on cable splices and greatly improves the efficiency of wrapping insulating tape on cable splices. Attached Figure Description

[0023] The left vertical plate 9 is provided with an upper mounting mechanism 26 for automatically mounting the sleeve 6 of the coiled material onto the mounting rod 20.

The piston rod of the feed cylinder 27 extends to the left through the left vertical plate 9, and a moving plate 28 is fixed to the extended end. A smooth rod 29 is fixed to the right end face of the moving plate 28. The cross-sectional diameter of the smooth rod 29 is equal to the inner diameter of the sleeve 6 of the coiled material.

[0028] A method for efficiently wrapping insulating tape around a cable splice includes the following steps: S1, the workers will be as follows Figure 3 The cable A1 is shown passing sequentially from right to left through the right cylinder 37, the right vertical plate 10, the square groove 15 in the movable plate 12, the center hole 17 of the toothed ring 16, the right vertical plate 10, and the left cylinder 37, ensuring that cable A1 is inside the left cylinder 37 and cable B3 is inside the right cylinder 37. Simultaneously, ensure that cable B3 is inside the center hole 17 of the toothed ring 16. Figure 23 As shown; S2. The worker tightens the locking screw 38 on the left cylinder 37.

The specific operation method is as follows: [The text abruptly ends here, so the translation stops as well.] S31. The moving part 14 of the linear cylinder 13 is controlled to move to the left. The moving part 14 drives the movable plate 12 to move to the left along the guide post 11. The movable plate 12 drives the gear ring 16, the tensioning mechanism 21, and the mounting rod 20 to move to the left synchronously. When the moving part 14 moves to the set distance, the controller controls the linear cylinder 13 to close. At this time, the center hole 17 of the gear ring 16 is just fitted onto the outside of the cable A1, and the tensioning mechanism 21 is just above the cable A1. Figure 25 As shown; S32. The piston rod of the feed cylinder 27 of the upper assembly mechanism 26 retracts to the right. The piston rod drives the moving plate 28 to move to the right. The moving plate 28 drives the guide rod 29 and the horizontal cylinder 30 to move to the right synchronously. The guide rod 29 drives each coil of material on it to move to the right synchronously. When the piston rod of the feed cylinder 27 retracts to the set stroke, the controller controls the feed cylinder 27 to close. At this time, the right end of the guide rod 29 is just close to the mounting rod 20 located on the gear ring 16. Figure 26 As shown; S33, the piston rod of the vertical cylinder 32 of the worker-controlled upper mechanism 26 extends downward, driving the clamping cylinder 33 to move downward. The clamping cylinder 33 drives the chuck 34 to move downward, and the chuck 34 moves towards the sleeve 6 of the first coil of material located on the guide rod 29. When the piston rod of the vertical cylinder 32 is fully extended, the chuck 34 is just placed on the outside of the sleeve 6 of the first coil of material. Figures 27-28 As shown; S34. The clamping cylinder 33 is activated, causing the clamping head 34 to close. The clamping head 34 clamps and fixes the sleeve 6 of the first coil of material. Figure 29 As shown; S35. The piston rod of the horizontal cylinder 30 of the upper assembly mechanism 26 extends to the right, driving the bracket 31 to move to the right. The bracket 31 drives the vertical cylinder 32 and the clamping cylinder 33 to move to the right synchronously, thereby driving the clamped sleeve 6 to move to the right. The sleeve 6 drives the insulating tape 5 wound on it to move to the right synchronously. When the piston rod of the horizontal cylinder 30 extends to the set stroke, the sleeve 6 of the first coil of material is just fitted onto the mounting rod 20. Figure 30 As shown; S36. Control the clamping cylinder 33 to close, the clamping cylinder 33 drives the chuck 34 to open, the chuck 34 releases the sleeve 6 of the first coil, that is, the chuck 34 no longer clamps the sleeve 6. S37. Control the piston rod of the vertical cylinder 32 to retract upwards, causing the clamping cylinder 33 to move upwards, which in turn causes the chuck 34 to move upwards; control the piston rod of the horizontal cylinder 30 to retract to the left, causing the support 31 to move to the left, and the support 31 causes the vertical cylinder 32 and the clamping cylinder 33 to move to the left synchronously. When the piston rod of the horizontal cylinder 30 retracts to the set stroke, the controller controls the horizontal cylinder 30 to close. At this time, the chuck 34 moves directly above the sleeve 6 of the second coil; control the piston rod of the feed cylinder 27 to extend to the left, causing the moving plate 28 to move to the left, the moving plate 28 to move the guide rod 29 to the left, and the guide rod 29 in turn causes each coil on it to move to the left synchronously, thus finally realizing the mounting of the coil on the mounting rod 20, such as Figures 31-32 As shown; As can be seen from step S3, this device, through the coordinated operation of the feed cylinder 27, horizontal cylinder 30, vertical cylinder 32, and clamping cylinder 33 of the upper assembly mechanism 26, can automatically mount the sleeve 6 of the first roll of material on the mounting rod 29 onto the mounting rod 20, thereby achieving the installation of the roll of material. This eliminates the need for workers to manually mount the roll of material onto the mounting rod 20, effectively preventing sweat from sticking to the insulating tape 5, and thus effectively preventing the insulating tape 5 wrapped around the cable fusion splice 4 from being punctured during the withstand voltage test of the cable fusion splice 4. Therefore, this device, compared to... Figures 5-12 The wrapping machine shown greatly improves the quality of wrapping insulating tape 5 on the cable splice 4.

[0029] S4. Wrap the insulating tape 5 from the coil around the cable fusion splice 4. The specific operation method is as follows: S41, the moving part 14 of the linear cylinder 13 is controlled to move to the right. The moving part 14 drives the movable plate 12 to move to the right along the guide post 11. The movable plate 12 drives the gear ring 16, the tensioning mechanism 21, and the mounting rod 20 to move to the right synchronously. When the moving part 14 moves to the set distance, the controller controls the linear cylinder 13 to close. At this time, the tensioning mechanism 21 moves to just above the left end of the cable fusion splice 4. Figure 33 As shown; S42. The worker pulls out the first end of the insulating tape 5 wrapped around the sleeve 6, then passes the first end of the insulating tape 5 through the area enclosed by the pressure strip 24 and the fixing rod 22 of the tensioning mechanism 21, and finally fixes the insulating tape 5 to the outer surface of the first section of the cable splice 4, as shown. Figures 34-35 As shown; S43. The worker turns on the drive motor 18, which drives the gear 19 to rotate. The gear 19 drives the gear ring 16 to rotate around its own axis. The gear ring 16 drives the tensioning mechanism 21 and the mounting rod 20 to rotate around the center line of the gear ring 16. Under centrifugal force, the pressure strip 24 on the tensioning mechanism 21 moves along the round rod 23 toward the fixed rod 22, thereby clamping the insulating tape 5 that passes between the fixed rod 22 and the pressure strip 24. At the same time, the mounting rod 20 drives the sleeve 6 of the rolled material on it to move synchronously. At this time, the insulating tape 5 wrapped on the sleeve 6 begins to be released and begins to wrap around the cable fusion splice 4. S44. The worker controls the moving part 14 of the linear cylinder 13 to move to the right. The moving part 14 drives the movable plate 12 to move to the right. The movable plate 12 drives the gear ring 16, the winding material, and the tensioning mechanism 21 to move to the right simultaneously. When the tensioning mechanism 21 moves to the right end of the cable splice 4, it can just wrap one turn of insulating tape 5 around the cable splice 4. Figure 36 As shown; S45. The moving part 14 of the linear cylinder 13 is controlled to reciprocate left and right. The moving part 14 drives the movable plate 12 to reciprocate left and right, and the movable plate 12 drives the gear ring 16 to reciprocate left and right, which in turn drives the coiled material to reciprocate left and right. During the reciprocating motion, the insulating tape 5 released from the sleeve 6 is gradually wound around the cable fusion splice 4 along its length. When all the insulating tape on the sleeve 6 is unwound and wound around the cable fusion splice 4, multiple turns of insulating tape 5 can be finally wound around a cable fusion splice 4. Figure 37 As shown, this ultimately achieves the goal of wrapping the insulating tape 5 from the coil onto the cable splice 4, resulting in the following structure: Figure 4 As shown; As can be seen from steps S43-S45, under the action of centrifugal force, the pressure bar 24 clamps the insulating tape 5 between the pressure bar 24 and the fixing rod 22. Therefore, the insulating tape 5, which passes between the fixing rod 22 and the pressure bar 24, is always clamped, thus applying a certain amount of damping to the insulating tape. This ensures that the insulating tape 5 located between the cable fusion splice 4 and the pressure bar 24 is always in a taut state, ensuring that the insulating tape 5 can always be firmly wrapped around the cable fusion splice 4. This effectively prevents the insulating tape 5 wrapped around the outside of the cable fusion splice 4 from being punctured during the withstand voltage test of the cable fusion splice 4. Therefore, this device is superior to... Figures 5-12 The wrapping machine shown greatly improves the quality of wrapping insulating tape 5 on the cable splice 4.

[0030] S5. After the cable splice 4 is wrapped, the worker turns off the drive motor 18, then loosens the locking screw 38, and finally removes the cable splice 4, cable A1 and cable B3 wrapped with insulating tape 5. S6. Workers can repeat steps S1 to S5 to continuously wrap insulating tape 5 around multiple cable fusion joints 4.

[0031] As can be seen from step S6, after the insulating tape 5 is wrapped around a cable splice 4, the worker only needs to use the linkage of the linear cylinder 13, the drive motor 18, and the upper assembly mechanism 26 to wrap the insulating tape 5 on each roll of material on the smooth rod 29 onto each cable splice 4 respectively. Therefore, this device, compared to... Figures 5-12 The winding machine shown does not require manual loading of the roll material, which greatly shortens the winding time and thus greatly improves the efficiency of winding the insulating tape 5 on the cable splice 4.
