Description

Technical Field

[0001] This application relates to the field of power maintenance technology, and more specifically, to an insulated rod type high-torque electric fastening combination tool. Background Technology

[0002] 5kV tension conductors using parallel groove clamps are mostly used on lines with long service lives. Because 35kV lines are mostly single-line power supplies, line defects often accumulate due to lack of ongoing maintenance and downtime. In particular, the hardware at key connection points suffers from oxidation of the conductors, loss of galvanized plating on the bolts, and severe corrosion. Over time, this leads to loosening and gaps at the parallel groove clamp connections. If not addressed promptly, this could result in the conductor being burned out. Currently, there are no suitable tools for indirect tightening and bolt replacement. Summary of the Invention

[0063] An insulated rod type high-torque electric fastening combination tool, including an adjustable insulated operating rod fixing bracket and an extended insulated electric fastening tool.

[0064] The extended insulated electric fastening tool includes a handle body 10, an extended insulated rod 11, a fastening mounting housing 12, a bolt locking assembly 13, and a transmission structure 14.

[0065] The grip body 10 is equipped with a drive unit. The extended insulating rod 11 includes a first insulating tube 15 and a second insulating tube 16 connected by a connecting assembly 17, with the first insulating tube 15 fixed to the grip body 10. A fastening mounting housing 12 is connected to the end of the second insulating tube 16. A bolt locking assembly 13 is disposed in the fastening mounting housing 12 and has a sleeve 13a for locking bolts. A transmission structure 14 is located within the extended insulating rod 11 and extends through the fastening mounting housing 12 for transmission connection with the bolt locking assembly 13, and the drive unit drives the sleeve 13a to rotate via the transmission structure 14.

[0066] The bolt locking assembly 13 includes a sleeve 13a for locking the bolt. The transmission structure 14 is connected to the bolt locking assembly 13.

[0067] The adjustable insulated operating rod fixing bracket includes a base assembly 40, a ball head connection assembly 41, a rack housing 42, a rack 43, a lifting handwheel 44, a fastening tool fixing assembly 45, a connecting bracket 46, and a coil assembly 47.

[0068] The base assembly 40 is used to detachably clamp onto the angle steel of the transmission line equipment. The ball joint assembly 41 is fixed to the base assembly 40. The rack housing 42 is equipped with a steering ball joint 48, which is connected to the ball joint assembly 41 and configured to be lockable by and positionally adjustable relative to the ball joint assembly 41. The rack 43 is vertically and vertically mounted within the rack housing 42. A lifting handwheel 44 is mounted on the rack housing 42 and equipped with a drive helical tooth 49 that meshes with the rack 43; the lifting handwheel 44 is used to drive the rack 43 to rise and fall. A fastening tool fixing assembly 45 is rotatably mounted on the end of the rack 43 and rises and falls with the rack 43, used to fix the extended insulating rod 11. The connecting bracket 46 is connected to the rack housing 42. The reel assembly 47 is fixed to the end of the connecting bracket 46 and is equipped with a winding handwheel 50 and an insulating wire 51. The insulating wire 51 is wound around the reel assembly 47. The winding handwheel 50 is used to wind and unwind the insulating wire 51. The free end of the insulating wire 51 is used to connect to the end of the extended insulating rod 11 near the sleeve 13a. With the help of a fastening tool, the rotatable connection between the fastening assembly 45 and the rack 43 is fixed, so it can be used to adjust the tilt angle of the extended insulating rod 11 around the rack 43. Figure 1 The upward and downward directions shown near point B in the middle represent its tilt direction.

[0069] In the above-described process, the extended insulated electric fastening tool, with its extended insulating rod 11, can tighten bolts at greater distances. The operator holds the main handle 10, places the sleeve 13a over the bolt, and activates the drive unit, causing the sleeve 13a to rotate, ultimately completing the bolt tightening. The extended insulated electric fastening tool is used to fix the tool to the angle steel of transmission line equipment. Its height, orientation, and tilt angle can be adjusted via the adjustable insulated operating rod fixing bracket to accommodate various types of bolts in transmission lines. Maintenance personnel can first fix the extended insulating rod 11 to the fastening tool fixing assembly 45, and then fix the base assembly 40 to the angle steel of the transmission line equipment, thereby completing the installation of the electric fastening tool. The maintenance personnel can adjust the position of the rack housing 42 (i.e., the extended insulating electric fastening tool) according to the position of the bolt to be tightened through the ball head connecting assembly 41, and adjust the rack 43 (i.e., the height of the extended insulating electric fastening tool) by rotating the lifting handwheel 44. The height can be adjusted by rotating the winding handwheel 50 and pulling the end of the extended insulating rod 11. Since the fastening tool fixing assembly 45 is rotatably mounted on the rack 43, the tilt angle of the extended insulating electric fastening tool can be adjusted.

[0070] In this disclosure, the connecting assembly 17 includes a cylindrical connecting screw 18 and a cylindrical connecting nut 19. The external thread of the connecting screw 18 is screwed onto the inner wall of the first insulating tube 15 and the inner wall of the connecting nut 19. The external thread of the connecting nut 19 is screwed onto the inner wall of the second insulating tube 16.

[0071] In the above process, the first insulating tube 15 and the second insulating tube 16 can be effectively assembled by connecting screw 18 and connecting nut 19 so that the length of the extended insulating rod 11 meets the actual working requirements.

[0072] The transmission structure 14 includes a first transmission rod 20, a second transmission rod 21, a first transmission connector 22, and a second transmission connector 23. One end of the first transmission rod 20 is connected to the drive unit, and the other end of the first transmission rod 20 is engaged with the first transmission connector 22. One end of the second transmission rod 21 is connected to the bolt locking assembly 13, and the other end of the second transmission rod 21 is engaged with the second transmission connector 23. The first transmission connector 22 is engaged with the second transmission connector 23.

[0073] In the above-described process, the first transmission connector 22 is engaged in the opening of the first transmission rod 20, and the second transmission connector 23 is engaged in the opening of the second transmission rod 21. The first transmission connector 22 is also engaged within the second transmission connector 23, effectively transmitting the torque of the first transmission connector 22 to the second transmission rod 21, ensuring that the power generated by the drive unit is smoothly transmitted to the bolt locking assembly 13. It should be noted that, to ensure smooth rotation of the first transmission rod 20 and the second transmission rod 21 within the extended insulating rod 11, the first transmission connector 22 is fitted with a bearing, which contacts the inner wall of the extended insulating rod 11 or the inner wall of the connecting screw 18.

[0074] The bolt locking assembly 13 includes a transmission assembly 26, a centrifugal flywheel 24, and a drive shaft 25.

[0075] The transmission assembly 26, the centrifugal flywheel 24, and the transmission shaft 25 are transmissively disposed within the fastening housing 12, and the second transmission rod 21 is transmissively connected to the fixed transmission unit in the transmission assembly 26.

[0076] The transmission assembly 26 is connected to the centrifugal flywheel 24, and one end of the transmission shaft 25 is fixed to the centrifugal flywheel 24, while the other end is fixed to the sleeve.

[0077] In the above process, the second transmission rod 21 transmits torque to the transmission assembly 26, and the power is transmitted through the centrifugal flywheel 24, which enables the sleeve to rotate smoothly under high torque so as to stably tighten the bolt.

[0078] Combination Figure 11 The transmission assembly 26 includes a first gear transmission disc 27 and a second gear transmission disc 28. The first gear transmission disc 27 is rotatably disposed at the end of the second insulating tube 16, and the second gear transmission disc 28 is provided with a movable cover 280, which is disposed in the fastening mounting housing 12. The second gear transmission disc 28 is rotatably disposed inside the movable cover and is connected to the centrifugal flywheel 24 for transmission. The free end of the insulating wire 51 is connected to the outer surface of the end of the second insulating tube 16.

[0079] The first gear transmission disc 27 has multiple first transmission tooth structures, and the second gear transmission disc 28 has multiple second transmission tooth structures. The first transmission tooth structures and the second transmission tooth structures mesh with each other.

[0080] The movable cover 280 is hinged to the end of the second insulating tube 16 so that the first gear transmission disk 27 and the second gear transmission disk 28 can rotate relative to each other to send changes in their relative positions, but there is always a partially meshing area between the first transmission gear structure and the second transmission gear structure so that transmission can be performed.

[0081] In the process described above, by adjusting the angle of the hinge between the movable cover 280 and the end of the second insulating tube 16, the tilt angle of the sleeve 13a relative to the extended insulating rod 11 can be adjusted, providing a wider working range for the extended insulating electric fastening tool and accommodating bolts in more positions.

[0082] The end of the second insulating tube 16 is provided with a hinged mounting bracket 281, and the hinged mounting bracket 281 is provided with an arc-shaped hole 282.

[0083] The wall of the movable cover 280 is provided with a hinge shaft 283, which passes through the arc-shaped hole 282 and can slide along the arc-shaped hole 282.

[0084] The first gear transmission disc 27 is rotatably mounted on the second insulating tube 16 via bearings. A transmission block is formed on one side of the first gear transmission disc 27, and the transmission block is inserted into the second transmission rod 21. The second transmission gear structure is connected to the centrifugal flywheel 24. A wear-resistant bushing 29 is fixed inside the fastening housing 12 and is fixed to the outer periphery of the transmission shaft 25.

[0085] It should be noted that the hinge shaft 283 can be screwed to the movable cover 280. By tightening the hinge shaft 283, it abuts against the hinge mounting bracket 281, and the movable cover 280 and the second insulating tube 16 maintain a stable angle.

[0086] The drive unit includes a battery module 30, a control switch, a drive module 31, and a reduction gear transmission module 32. The battery module 30 is built into the grip body 10, and a charging port 33 corresponding to the battery module 30 is formed on the outer side of the grip body 10. The battery module 30 is configured to be rechargeable and dischargeable, and is used to supply power to the drive module 31. The drive module 31 is built into the grip body 10, and the control switch is located on the outer surface of the grip body 10. The control switch is used to control the working state of the drive module 31. The drive module 31 is connected to the reduction gear transmission module 32. The reduction gear transmission module 32 is built into the grip body 10 and is connected to the transmission structure 14.

[0087] During the above process, maintenance personnel can control whether the drive module 31 works and control the direction of its output power by controlling the control switch; at the same time, the battery module 30 can be conveniently charged by connecting a charger through the charging port 33.

[0088] In this disclosure, the drive module 31 includes a motor, and the control switches include a power switch 34 and a forward / reverse switch 35.

[0089] The power switch 34 is used to control the connection between the battery module 30 and the motor, and the forward / reverse switch 35 is used to control the direction of the motor. The drive unit also includes a display screen 36, which is connected to the battery module 30 and is used to display the status of the battery module 30.

[0090] In the above process, the battery module 30 is turned on by the battery switch to supply power to the motor, and the voltage and remaining percentage of the power module can be observed on the display screen 36; the direction of the motor is controlled by the forward / reverse switch 35 to achieve the effect of tightening or loosening the bolts.

[0091] It should be noted that the battery module 30 includes a lithium battery, and the hand-held body 10 forms a battery box. The lithium battery is locked in the battery box by a battery buckle 37. At the same time, a battery protective layer 38 is also provided to protect the lithium battery.

[0092] It should be noted that the reduction transmission module 32 includes a reduction gear, the output shaft of the motor is provided with a transmission gear, the transmission gear meshes with the reduction gear, and the reduction gear is fixed to the end of the transmission structure 14.

[0093] Meanwhile, a grip groove 39 is formed on the top of the grip body 10. Maintenance personnel can grasp the grip groove 39 on the top of the grip body 10 to easily pick up and operate the extended insulated electric fastening tool.

[0096] The clamping plate 55 is located inside the clamping seat 52 and fixed to the end of the locking screw 53.

[0097] During the above process, by turning the locking handle 54, the distance between the clamping plate 55 and the top of the clamping seat 52 can be adjusted, so that the clamping seat 52 can be easily fixed or removed from the angle steel.

[0098] In this disclosure, the ball joint assembly 41 includes a spherical housing 56, a locking knob 57, an adjusting knob 58, a turbine 59, and a connecting plate 60;

[0099] The turbine 59 is vertically and retractably disposed in the slot of the spherical housing 56 (see...). Figure 4 As indicated by C, the edge of the turbine 59 forms a limiting piece, and the inner wall of the spherical housing 56 forms a strip groove (the limiting piece can slide along the strip groove) to lock the steering ball joint 48. The locking knob 57 is equipped with an adjusting worm gear 57a, which meshes with the turbine 59 to lock or release the steering ball joint 48.
