Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Figure 1 The figure shows a schematic structural diagram of the multi-type pigtail quick tube threading device of the present invention, wherein the multi-type pigtail quick tube threading device comprises a driving unit, a transmission unit 4, a pigtail pulling unit and a pigtail connecting unit.

[0030] The drive unit includes a power module 7 and a motor 2 connected to the power module 7. The power module 7 is used to provide working power to the motor 2. In this embodiment, the power module 7 is a DC power module, for example, a lithium battery can be used. The battery life is more than 5 hours and the power loss is less than 10% after charging and discharging experiments. The power module 7 and the motor 2 are installed in a protective housing, such as Figure 1 As shown, the protective shell is designed to be in the shape of a pistol, including a grip, a barrel, etc., for easy operation, and the material can be made of aluminum alloy.

[0031] like Figure 2 As shown, the transmission unit 4 includes a gear bearing fixed front seat 41, a driving gear bearing 42, a passive gear bearing 43, a driving gear 44, a passive gear 45, a motor connecting shaft 46, a gear spiral sleeve 47, a rear gear bearing seat 48, and a motor connecting platform 49. The transmission unit 4 is fixedly installed at the front end of the barrel of the protective shell.

[0032] The gear bearing fixing front seat 41 provides support and positioning for the driving gear bearing 42 and the passive gear bearing 43. The driving gear 44 and the passive gear 45 are respectively installed on the driving gear bearing 42 and the passive gear bearing 43. The rear gear bearing seat 48 cooperates with the gear bearing fixing front seat 41 to install and limit the driving gear bearing 42 and the passive gear bearing 43. The rear gear bearing seat 48 is fixed to the rear of the transmission unit 4 to ensure its stability and accurate positioning.

[0033] The motor connection platform 49 is used to fix the motor 2 to the rear gear bearing seat 48. The motor connection platform 49 is the installation base of the motor 2, providing support for the motor 2 to ensure that the motor 2 does not move during operation. The motor 2 is connected to the driving gear 44 through the motor connection shaft 46, and the driving gear 44 is meshed and connected with the passive gear 45. The rotation of the motor 2 is transmitted to the driving gear 44 through the motor connection shaft 46, driving the driving gear 44 to rotate, and then driving the passive gear 45 to rotate. The passive gear 45 is installed in the gear spiral sleeve 47. The gear spiral sleeve 47 moves under the drive of the passive gear 45, driving the spiral plastic steel wire 3 passing through it to advance and retreat, completing the function of winding or releasing the line.

[0034] In this embodiment, the driving gear 44 and the driven gear 45 form a threaded gear power device, with a designed speed range of 100-2000r / min and a maximum efficiency of 97.5%, meeting the requirements of high-efficiency transmission.

[0035] The spiral plastic steel wire 3 is wound on the wire drum 1 and connected to the gear spiral sleeve 47. The material and structure of the spiral plastic steel wire 3 should have sufficient strength and flexibility to withstand tension and bending.

[0036] The gear spiral sleeve 47 realizes forward and backward movement through the drive of the motor 2. Its design enables the rotation of the motor 2 to be effectively converted into the winding and releasing action of the wire drum 1.

[0037] like Figure 1 As shown, the protective housing is also provided with a control switch 5 and a motor drive switch 6, the control switch 5 is connected to the gear spiral sleeve 47, and the control switch 5 is used to control the positive and negative directions of the gear spiral sleeve 47. The user can select the mode of winding or releasing the line by operating the control switch 5. The motor drive switch 6 is used to start or stop the work of the motor 2, and can be linked with the control switch 5 to control the operation of the motor 2 when needed.

[0038] The pigtail traction unit includes a wire drum 1 and a spiral plastic steel wire 3 wound on the wire drum 1, the front end of the spiral plastic steel wire 3 passes through the transmission unit 4, specifically, the rear gear bearing seat 48 and the gear bearing fixed front seat 41 are correspondingly provided with through holes, and the gear spiral sleeve 47 is correspondingly provided with threaded holes, the front end of the spiral plastic steel wire 3 passes through the through holes of the rear gear bearing seat 48, the threaded holes of the gear spiral sleeve 47 and the through holes of the gear bearing fixed front seat 4 in sequence, and the tail end of the spiral plastic steel wire 3 is connected to the pigtail connection unit, and the pigtail connection unit is used to connect the pigtail 9. In the present invention, the driving unit is responsible for providing power support and feeding back to the transmission unit 4 to ensure that the transmission unit 4 can perform mechanical transmission, and the transmission unit 4 transmits mechanical energy to the pigtail traction unit, and the pigtail traction unit pulls the pigtail 9 through the pigtail connection unit.

[0039] See also Figure 3-5The pigtail connection unit includes an arc ball head 81, a pipe base 82, a winding rod 83, a wire rope winding portion 84, a wire rope straight portion 85, a flange head 86, a pull ring 87, and a threading hole 88.

[0040] One end of the tube-threading base 82 is provided with a threading hole 88, in which a pull ring 87 is provided; the other end of the tube-threading base 82 is provided with a winding rod 83, on which multiple strands of steel wire ropes are tightly wound in the same direction, and the steel wire ropes extend from the lower end of the winding rod 83. The portion of the steel wire rope located at the winding position of the winding rod 83 is the steel wire rope winding portion 84, and the portion located outside the winding position of the winding rod 83 is the steel wire rope straight portion 85. The lower end of the steel wire rope straight portion 85 is connected with a flange head 86, and the flange head 86 is used to connect the pigtail 9. All flange heads are sequentially extended and staggered from top to bottom, so that the connected pigtails 9 can be well ensured not to overlap and squeeze each other. Preferably, the number of strands of the steel wire rope is an even number, and each pair of flange heads 86 is used to connect the same type of pigtails. The pigtail 9 is put on the pigtail connection unit, and the pigtail traction unit drives the pigtail connection unit to move, so that the pigtail 9 is automatically threaded along the path and reaches the target position.

[0041] Preferably, in another embodiment, Figure 6 As shown, a conical protective cover 10 is set at the connection between the flange head 86 and the spiral plastic steel wire 3. The conical protective cover 10 is made of PVC plastic. The setting of the conical protective cover 10 can protect the head of the pigtail 9 from being damaged in the corrugated tube during the wire pulling process, thereby affecting the communication quality. By installing a conical protective cover 10 on the spiral plastic steel wire 3 and hanging 10 pigtails of 4 types at the same time, a simulated pipe wearing experiment was conducted 100 times, and the damage of the pigtails was recorded. The results showed that the amount of pigtail damage was 0 and the pigtail damage rate was 0%.

[0042] Preferably, in another embodiment, a heat shrink tubing may be sleeved on the spiral plastic-steel wire 3 to effectively protect the spiral plastic-steel wire 3 and also play an insulating role.

[0043] The working principle of the present invention is as follows:

[0044] First, tie the tail end of the spiral plastic steel wire 3 wound on the reel 1 to the pull ring 87 of the tube base 82, and then connect the flange head 86 on the end of the straight part 85 of the wire rope to various types and models of pigtails one by one. The flange heads 86 are arranged in sequence and staggered. Each flange head 86 corresponds to a model of pigtail. In actual operation, a corresponding identification mark can be placed on the flange head 86.

[0045] After the front end of the spiral plastic steel wire 3 is passed through the transmission unit 4, it is aligned with the entrance of the pipeline, and the power module 7 provides power to the motor 2 and the control switch 5 to ensure that the system can work normally. The user selects the rotation direction of the gear spiral sleeve 47 through the control switch 5, thereby controlling the winding and releasing action of the wire drum 2, rotating forward to receive the wire, and rotating reversely to release the wire. When the user starts the motor 2 through the motor drive switch 6, the motor 2 starts to rotate, and the motor 2 drives the transmission unit 4, so that the spiral plastic steel wire 3 is driven by the motor 2, and the movement of the gear spiral sleeve 47 realizes the advance and retreat of the spiral plastic steel wire 3, and completes the function of winding or releasing the spiral plastic steel wire 3 in the pipeline. After the spiral plastic steel wire 3 passes through the pipeline, the spiral plastic steel wire 3 is slowly pulled again. Since the tail end of the spiral plastic steel wire 3 is connected to multiple pigtails through the pigtail connection unit, multiple pigtails can be easily passed through the pipe together, and finally accurate, convenient and fast pigtail pipe passing operation is realized. Through field testing, the average deployment time of the device of the present invention is 7.9 minutes, and the success rate is 100%.

[0046] In June 2024, the inventor of this application invited communication professionals from other power grid companies in Hubei to use the pigtail threading device for testing and record the time required to lay the pigtail during the experiment. As shown in Table 1, 8 different companies were selected to conduct tool effect tests. No safety issues occurred during the use of the tool, the average time consumption was 15 minutes lower than the target setting value, and the success rate was 100%.

[0048]

[0049] The present invention realizes the function of quickly laying out multiple types of pigtails during maintenance. Maintenance personnel can use the laid corrugated pipes for laying, which reduces the laying time and reduces the safety risks of on-site operations. It improves the efficiency of on-site operation and maintenance, and reduces the cost of operation and maintenance and troubleshooting by a total of 620,000 yuan per year, as shown in Table 2.
