Abstract
Description
Technical Field
[0001] This invention relates to a power operation tool, and more specifically, to an electric piercing tool for live-line work on 10KV insulated wires and insulated poles. Background Technology
[0002] Currently, to address the safety issues of overhead power distribution lines and the surrounding buildings, bamboo, trees, and other vegetation along the line corridors, insulated conductors are widely used in the installation of overhead power distribution lines. For these lines, connections are made by stripping the insulation or using piercing clamps. Traditionally, using piercing clamps requires shutting down the overhead power line, which directly impacts customers' normal production and daily life. Due to limitations in power supply reliability, power outages are difficult to implement, so connections to customers and branches require live-line work. Commonly used methods include: 1. Stripping the insulation before connection. This method introduces numerous safety hazards to the insulated conductors, such as water ingress and reduced mechanical strength. 1. Rainwater entering insulated conductors can cause them to overheat and break during operation due to prolonged water accumulation, directly affecting the safe operation of overhead power distribution lines. 2. Using piercing clamps for connection can avoid the problems that occur during conductor stripping. However, when piercing clamps, workers can only use insulated gloves for live work and need to have an insulated platform or use insulated bucket trucks or other live work equipment. This increases the safety risks of live work and reduces work efficiency. Summary of the Invention
[0003] To overcome the above shortcomings, this invention provides a 10KV insulated wire and insulated pole live-line working electric piercing tool. It assists the piercing clamp to connect to the circuit by piercing. The operator can work while standing on the ground, without the need to build an insulated platform or insulated bucket truck or other live-line working equipment, thus avoiding the safety hazards caused by stripping the insulation of the wire.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a 10KV insulated conductor and insulating rod live-line electric piercing tool, comprising a body, an insulating rod, and a clamp positioning seat. A drive shaft driven by a motor is installed on the body. The insulating rod is movably fitted outside the drive shaft. The insulating rod is connected between the body and the clamp positioning seat. The clamp positioning seat is provided with a clamp mounting groove for clamping the piercing clamp. Two driven shafts driven by the drive shaft are installed on the clamp positioning seat. The upper end of the driven shaft is provided with a tightening groove that matches the bolt on the piercing clamp.
[0005] When installing insulated conductors in power distribution lines, piercing clamps are used for connection. During the connection operation, the piercing clamp is first inserted into the clamp mounting slot on the clamp positioning seat, and the conductor to be connected is threaded through the piercing slot on the piercing clamp. The bolt on the piercing clamp is fitted into the tightening slot. The operator stands on the ground, holds the machine body, and lifts the clamp positioning seat upwards, inserting the other piercing slot on the piercing clamp into the installed insulated conductor. The motor starts, driving the drive shaft to rotate, which in turn drives the two driven shafts to rotate synchronously. The driven shafts tighten the bolt on the piercing clamp, thus clamping the insulated conductor and piercing it. The bolt on the piercing clamp is a torque bolt; when the tightening force of the piercing clamp reaches the limit value of the torque bolt, the bolt head is broken off. At this point, the piercing clamp achieves the best piercing effect on the insulated conductor. Next, the clamp positioning seat is moved outward, separating from the piercing clamp, leaving the piercing clamp on the insulated wire, thus completing the piercing operation of the piercing clamp.
[0006] The electric piercing tool of this application assists in connecting to the circuit via piercing with a wire clamp. The operator can work standing on the ground, eliminating the need for insulated platforms or insulated boom trucks and other live-line working equipment, thus avoiding the safety hazards associated with stripping insulated wires. This piercing method is not limited by the terrain of the working environment, effectively reducing personal safety risks and improving work efficiency.
[0007] Preferably, the upper end of the driven shaft is provided with an installation notch for the bolt on the piercing clamp to pass through, and the installation notch connects between the screwing groove and the outer wall of the driven shaft.
[0008] The installation notch facilitates the installation of the bolt head into the screwing slot during the process of loading the piercing clamp into the clamp mounting slot.
[0009] Preferably, a driving gear is installed on the driving shaft and a driven gear is installed on the driven shaft. Both driven gears mesh with the driving gear for transmission, while the two driven gears are separated from each other.
[0010] The transmission uses gears, ensuring smooth and reliable operation. The two driven gears are separated to guarantee that the two driven shafts rotate in the same direction, preventing them from contacting and jamming.
[0011] Preferably, the main unit is connected to a power bank via a cable. Using a power bank makes the use of power tools more flexible and convenient.
[0012] Preferably, the lower side wall of the clamp mounting slot is provided with a clearance slot corresponding to the driven shaft.
[0013] The clearance slot is designed to facilitate the passage of bolts on the piercing wire clamp.
[0014] As a preferred design, the device is handheld and equipped with a handle.
[0015] The device is designed for handheld operation, making it easy to use.
[0016] Preferably, a spring pin is installed on the upper side wall of the wire clamp mounting slot, a positioning spring is installed between the spring pin and the wire clamp positioning seat, and an inclined guide surface is provided on the lower end face of the spring pin.
[0017] During the process of inserting the piercing clamp into the clamp mounting slot, the upper end of the piercing clamp slides over the guide surface, and the end of the spring pin abuts against the upper surface of the piercing clamp, thereby achieving reliable positioning of the piercing clamp and preventing the piercing clamp from detaching from the clamp mounting slot.
[0018] Preferably, the clamp positioning seat is equipped with an anti-dislodgement cover to prevent the puncture clamp from slipping off.
[0019] After the piercing clamp is installed into the clamp mounting slot, the anti-detachment cover blocks the piercing clamp to prevent it from coming off the clamp mounting slot. Furthermore, if the torque bolt head breaks off, the anti-detachment cover prevents it from slipping down, thus preventing the bolt head from falling and posing a safety hazard to the operator.
[0020] Preferably, the piercing clamp includes an upper clamping part and a lower clamping part, and a preload spring is installed between the upper clamping part and the lower clamping part.
[0021] The preload spring ensures that the upper and lower clamping parts can be reliably clamped in the wire clamp mounting slot.
[0022] Preferably, an anti-disengagement cover plate for preventing puncture of the wire clamp is installed on the wire clamp positioning seat. The anti-disengagement cover plate has a rotating shaft, and the anti-disengagement cover plate is rotatably mounted on the wire clamp positioning seat via the rotating shaft. A rotating column, a transition shaft, and a connecting seat are installed on the wire clamp positioning seat, and the rotating column and the transition shaft are connected by transmission. A movable gear is installed on the rotating column, and a fixed gear is installed on a driven shaft. The axial movement of the movable gear achieves engagement or disengagement with the fixed gear. A return spring is installed between one side of the movable gear and the rotating column, and a push bar for pushing the movable gear is installed on the other side of the movable gear. The outer end of the push bar has a push head, and the anti-disengagement cover plate covers the push head. The end of the push head has a conical pushing surface. The anti-detachment cover is provided with a positioning groove for ejecting the push head; a clutch seat with axial movement is installed on the rotating shaft, a return spring is installed between the clutch seat and the rotating shaft, several locking pins are installed on the clutch seat, and several locking holes corresponding to the locking pins are provided on the transition shaft; a connecting rod and a push column are installed on the connecting seat, the end of the push column is provided with a tapered push head, a driven shaft has a positioning groove on its outer wall that corresponds to and matches the push head, the connecting rod is hinged to the connecting seat, one end of the connecting rod abuts against the clutch seat to push the clutch seat to move, the other end of the connecting rod is provided with a connecting groove, and a connecting pin is connected between the connecting groove and the push column; when the push head is inserted into the positioning groove, the mounting notch faces the anti-detachment cover.
[0023] Before each installation of the piercing clamp into the clamp mounting slot, the mounting notch on the driven shaft must face the opening of the clamp mounting slot. Only in this way can the piercing clamp be installed into the clamp mounting slot, and the bolt head on the piercing clamp must be aligned with the mounting notch before being screwed into the slot. However, often after the previous operation, the mounting notch is in any position, so before the next operation, the driven shaft needs to be manually adjusted to ensure the mounting notch faces the opening of the clamp mounting slot. This design makes the adjustment of the driven shaft much more convenient.
[0024] After the piercing operation of the piercing clamp is completed, the clamp positioning seat is lowered. At this time, the anti-detachment cover is rotated to facilitate the removal of the broken bolt head. During the rotation of the anti-detachment cover, if the push head is inserted into the positioning groove, the installation notch faces the anti-detachment cover. In other words, the position of the driven shaft does not need to be adjusted. At this time, the locking pin on the clutch seat separates from the locking hole on the transition shaft, and the transition shaft and rotating column will not be driven to rotate. In reality, the push head is often not aligned with the positioning groove. Instead, it abuts against the outer wall of the driven shaft. At this time, the clutch seat is pushed towards the transition shaft by the connecting rod, causing the locking pin to insert into the locking hole. The rotating shaft drives the transition shaft and the rotating column to rotate. Because the anti-detachment cover rotates, the positioning groove and the push head are misaligned, causing the push head to be pushed inward. This causes the push bar to push the movable gear to move axially, making the movable gear mesh with the fixed gear for transmission. At this time, the orientation of the installation notch for adjusting the driven shaft can be achieved. When the orientation of the installation notch is adjusted to the correct position, the push head is inserted into the positioning groove, the connecting rod returns to its original position, and under the action of the return spring, the locking pin separates from the locking hole. At this time, the rotating shaft no longer drives the driven shaft to rotate.
[0025] When the driven shaft is driven by the drive shaft, since the shaft remains stationary in its initial position, the push head pops out of the positioning slot, separating the moving gear from the fixed gear. During this rotation, the driven shaft moves once per revolution via the connecting rod without affecting the anti-detachment cover. While the anti-detachment cover rotates to unload the broken bolt head, it simultaneously adjusts the position of the mounting notch on the driven shaft without requiring additional adjustments. This precise and reliable position adjustment facilitates subsequent piercing operations with the piercing clamp.
[0026] Compared with the prior art, the beneficial effects of the present invention are: (1) The electric piercing tool of this application is used to assist the piercing clamp in the piercing method to connect the circuit. The operator can stand on the ground to carry out the work. There is no need to build an insulated platform or an insulated bucket truck or other live work equipment for construction, which avoids the safety hazards caused by stripping the insulation wire; (2) The piercing operation method of this application is not limited by the terrain of the working environment, which more effectively reduces the personal safety risk of the operator and improves the work efficiency; (3) The electric tool assisted piercing clamp of this application is convenient and reliable to operate and has high work efficiency.

[0036] The technical solution of the present invention will be further described in detail below through specific embodiments and with reference to the accompanying drawings:
[0037] Example 1: An electric piercing tool for live-line working on 10KV insulated wires and insulated poles (see attached document) Figure 1 To be continued Figure 4 The system includes a body 1, an insulating rod 2, and a wire clamp positioning seat 3. A drive shaft 4, driven by a motor, is mounted on the body. The insulating rod is movably fitted outside the drive shaft and connects the body to the wire clamp positioning seat. The wire clamp positioning seat is equipped with a clamping clip 5 for holding piercing wires (see appendix). Figure 5 The clamp mounting slot 6 is provided. The piercing clamp includes an upper clamping part 7 and a lower clamping part 8, with a preload spring 9 installed between the upper and lower clamping parts. Two driven shafts 10, driven by the drive shaft, are mounted on the clamp positioning seat. The upper end of the driven shaft has a tightening groove 12 that matches the bolts 11 on the piercing clamp. By changing the insulating rods and drive shafts of different lengths, the piercing clamps for insulated wires at different heights can be installed.
[0038] A driving gear 13 is mounted on the drive shaft, and a driven gear 14 is mounted on the driven shaft. Both driven gears mesh with the driving gear, and are staggered vertically to maintain their separation. The main unit is connected to a power supply 15 via a wire. A motor is installed inside the unit, and the power supply powers the motor. A worm gear is mounted on the motor's output shaft, and a worm wheel is mounted at the lower end of the drive shaft. The worm gear and worm wheel are coupled for transmission. The unit is handheld and has a handle 16.
[0039] The driven shaft has an installation notch 17 at its upper end for the bolts on the piercing clamp to pass through. The installation notch connects the screwing groove and the outer wall of the driven shaft. A clearance groove 18 is provided on the lower side wall of the clamp mounting groove, corresponding to the driven shaft. An anti-detachment cover 19 for blocking the piercing clamp is installed on the clamp positioning seat. The anti-detachment cover is positioned opposite to the upper part of the driven shaft. The anti-detachment cover is rotatably mounted on the clamp positioning seat. When rotated upwards to a horizontal position to cover the upper part of the driven shaft, the anti-detachment cover is rotated downwards to a horizontal position to expose the upper part of the driven shaft.
[0040] Three spring pins 20 are installed on the upper side wall of the wire clamp mounting slot. A positioning spring 21 is installed between the spring pins and the wire clamp positioning seat. An inclined guide surface 22 is provided on the lower end face of the spring pin. Protective plates 23 are provided on both the upper and lower sides of the wire clamp mounting slot. The protective plates protect the piercing wire clamp installed in the wire clamp mounting slot and prevent the piercing wire clamp from falling out of the wire clamp mounting slot.
[0041] When installing insulated conductors in power distribution lines, piercing clamps are used for connection. During the connection operation, the piercing clamp is first inserted into the clamp mounting slot on the clamp positioning seat, and the conductor to be connected is threaded through the piercing slot on the piercing clamp. The bolt on the piercing clamp is fitted into the tightening slot. The operator stands on the ground, holds the machine body, and lifts the clamp positioning seat upwards, inserting the other piercing slot on the piercing clamp into the installed insulated conductor. The motor starts, driving the drive shaft to rotate, which in turn drives the two driven shafts to rotate synchronously. The driven shafts tighten the bolt on the piercing clamp, thus clamping the insulated conductor and piercing it. The bolt on the piercing clamp is a torque bolt; when the tightening force of the piercing clamp reaches the limit value of the torque bolt, the bolt head is broken off. At this point, the piercing clamp achieves the best piercing effect on the insulated conductor. Next, the clamp positioning seat is moved outward, separating from the piercing clamp, leaving the piercing clamp on the insulated wire, thus completing the piercing operation of the piercing clamp.
[0042] The electric piercing tool of this application assists in connecting to the circuit via piercing with a wire clamp. The operator can work standing on the ground, eliminating the need for insulated platforms or insulated boom trucks and other live-line working equipment, thus avoiding the safety hazards associated with stripping insulated wires. This piercing method is not limited by the terrain of the working environment, effectively reducing personal safety risks and improving work efficiency.
[0043] Example 2: An electric piercing tool for live-line working on 10KV insulated wires and insulated poles (see attached document) Figure 6 To be continued Figure 8 Its structure is similar to that of Embodiment 1, the main difference being that in this embodiment, an anti-detachment cover plate for blocking the puncture clamp is installed on the clamp positioning seat. The anti-detachment cover plate is provided with a rotating shaft 24, and the anti-detachment cover plate is rotatably mounted on the clamp positioning seat via the rotating shaft. A rotating column 25, a transition shaft 26, and a connecting seat 27 are installed on the clamp positioning seat. The rotating column and the transition shaft are connected by a transmission. A driving bevel gear 28 is installed on the transition shaft, and a driven bevel gear 29 is installed on the rotating column. The driving bevel gear and the driven bevel gear mesh and transmit power. A movable gear 30 is installed on the rotating column, and a fixed gear is installed on a driven shaft. Gear 31, the axial movement of the movable gear achieves engagement or disengagement with the fixed gear. A return spring 32 is installed between one side of the movable gear and the rotating column. A push bar 33 for pushing the movable gear is installed on the other side of the movable gear. A push head 34 is provided at the outer end of the push bar. An anti-detachment cover plate covers the push head. The end of the push head has a conical pushing surface. The anti-detachment cover plate has a positioning groove 35 for ejecting the push head. The push bar has an inclined pushing surface. The movable gear has a top block 36. The movement of the push bar causes the pushing surface to abut against the top block, thereby pushing the movable gear to move axially. An axially arranged protrusion 37 is provided on the inner wall of the movable gear. A groove 38 adapted to the protrusion is provided on the outer wall of the rotating column. The protrusion and the groove are adapted to each other.
[0044] A clutch seat 39 with axial movement is installed on the rotating shaft. A return spring 40 is installed between the clutch seat and the rotating shaft. A spring seat 41 is connected to the end of the rotating shaft. A protruding ring 42 is provided on the inner wall of the clutch seat. The return spring abuts between the spring seat and the protruding ring. The protruding ring abuts against the end of the rotating shaft. An anti-rotation rib 43 is provided on the inner wall of the clutch seat with axial arrangement. An anti-rotation groove 44 corresponding to and adapted to the rib is provided on the outer wall of the rotating shaft. The rib and the anti-rotation groove are adapted to each other. A number of locking pins 45 are installed on the clutch seat, and a number of locking holes 46 corresponding to the locking pins are provided on the transition shaft. A connecting rod 47 and a push column 48 are installed on the connecting seat. The push column is movably mounted on the connecting seat, and a tapered push head 49 is provided at the end of the push column. A driven shaft has a positioning groove 50 on its outer wall that corresponds to and matches the push head. The connecting rod is hinged to the connecting seat. One end of the connecting rod abuts against the clutch seat to push the clutch seat to move. The other end of the connecting rod has a connecting groove 51. A pin 52 is connected between the connecting groove and the push column. When the push head is inserted into the positioning groove, the mounting notch faces the anti-detachment cover. A buffer spring 53 is connected between the locking pin and the clutch seat to give the locking pin a buffer function, so as to avoid the locking pin hitting the end face of the transition shaft and causing jamming, which would affect the normal operation of the driven shaft. An end face bearing 54 is connected to the clutch seat, and the end of the connecting rod abuts against the end face of the end face bearing. Other structures are the same as in Embodiment 1.
[0045] After the piercing operation of the piercing clamp is completed, the clamp positioning seat is lowered. At this time, the anti-detachment cover is rotated to facilitate the removal of the broken bolt head. During the rotation of the anti-detachment cover, if the push head is inserted into the positioning groove, the installation notch faces the anti-detachment cover. In other words, the position of the driven shaft does not need to be adjusted. At this time, the locking pin on the clutch seat separates from the locking hole on the transition shaft, and the transition shaft and rotating column will not be driven to rotate. In reality, the push head is often not aligned with the positioning groove. Instead, it abuts against the outer wall of the driven shaft. At this time, the clutch seat is pushed towards the transition shaft by the connecting rod, causing the locking pin to insert into the locking hole. The rotating shaft drives the transition shaft and the rotating column to rotate. Because the anti-detachment cover rotates, the positioning groove and the push head are misaligned, causing the push head to be pushed inward. This causes the push bar to push the movable gear to move axially, making the movable gear mesh with the fixed gear for transmission. At this time, the orientation of the installation notch for adjusting the driven shaft can be achieved. When the orientation of the installation notch is adjusted to the correct position, the push head is inserted into the positioning groove, the connecting rod returns to its original position, and under the action of the return spring, the locking pin separates from the locking hole. At this time, the rotating shaft no longer drives the driven shaft to rotate.
[0046] When the driven shaft is driven by the drive shaft, since the shaft remains stationary in its initial position, the push head pops out of the positioning slot, separating the moving gear from the fixed gear. During this rotation, the driven shaft moves once per revolution via the connecting rod without affecting the anti-detachment cover. While the anti-detachment cover rotates to unload the broken bolt head, it simultaneously adjusts the position of the mounting notch on the driven shaft without requiring additional adjustments. This precise and reliable position adjustment facilitates subsequent piercing operations with the piercing clamp.
[0047] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications may be made without departing from the technical solutions described in the claims.
