Description

Technical Field

[0001] This utility model relates to the field of electrical equipment maintenance technology, and in particular to a portable live-line working auxiliary device. Background Technology

[0002] With the increase in daily electricity consumption, the failure rate of power supply lines has also increased. Each power outage causes significant economic losses. To improve power supply stability, live-line work has become the norm. During maintenance, workers wear insulated clothing and gloves to perform lead wire splicing. After measuring and fabricating a lead wire of a certain length, it is hung along the arc of the lead wire on the terminal of the corresponding phase load switch (or drop-out fuse). When splicing the lead wire, workers inside the insulated bucket truck use an insulated hook to hook up the lead wire of the corresponding phase, and then hold the lead wire to perform live splicing and tighten the clamp bolts. Workers are exposed to voltages of phase voltage or higher without only auxiliary insulation protection (insulated gloves). Workers inside the bucket face significant safety risks, especially when splicing long unloaded leads. Due to the large capacitance effect of the line, the intermittent burning of the arc between the lead wire ends during the connection process generates overload voltage, greatly increasing the risk of accidents.

[0003] In conclusion, developing an auxiliary device for live-line work that assists in completing lead wire repairs and reduces construction risks is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a portable live-line working auxiliary device, which solves the technical problem that currently workers only perform live-line work under the protection of auxiliary insulating tools, greatly increasing the risk of accidents.

[0005] To achieve the above objectives, this utility model provides a portable live-line working auxiliary device, comprising:

[0006] The support plate is specifically I-shaped. The vertical plate of the support plate is provided with a first pressing assembly and a second pressing assembly on both sides. The first pressing assembly, the second pressing assembly and the first horizontal plate of the support plate are all connected to a pushing assembly. The feeding direction of the pushing assembly is parallel to the vertical plate. Twisting each pushing assembly makes the first pressing assembly and the second pressing assembly clamp the lead wire and the main line. The support plate is provided with a rope sleeve. The end of the rope sleeve is connected to a hook, and the hook is hooked to the main line.

[0007] Preferably, both the first and second wire pressing assemblies include a first pressing block and a second pressing block that are symmetrical to each other. The first pressing block and the second pressing block are arranged sequentially along the length of the vertical plate, and curved grooves are provided on their opposite end faces. Each curved groove is used to accommodate the lead wire and the main wire.

[0008] Preferably, the bearing plate further includes a second horizontal plate, which is arranged parallel to the first horizontal plate. Two fixed shafts are threaded through the second horizontal plate, and the ends of each fixed shaft are fixedly connected to each second clamping block. The other end of each fixed shaft is connected to a push-pull clamping device, which is used to lock the fixed shaft.

[0009] Preferably, the pushing assembly includes a pushing screw threaded to the first horizontal plate, and a screwing member is sleeved on the outer periphery of the end of the pushing screw away from the first pressing assembly. The pushing screw is connected to the first pressing block, and by rotating the screwing member, the pushing screw drives the first pressing block to move.

[0010] Preferably, the first pressing block and the second pressing block are respectively provided with a first locking hole and a second locking hole on their side walls. The first locking hole extends to the side wall of the push screw, and the second locking hole extends to the side wall of the fixed shaft. Locking elements are screwed into both the first locking hole and the second locking hole. Each locking element is used to lock the relative positions of the first pressing block and the push screw, and the second pressing block and the fixed shaft.

[0011] Preferably, an adjusting nut is screwed onto the outer circumference of one end of the fixed shaft near the second pressing block. The adjusting nut abuts against the bottom surface of the second pressing block. Tightening the adjusting nut is used to adjust the distance between the second pressing block and the second horizontal plate.

[0012] Preferably, the second horizontal plate has a connecting hole on its side wall, and a hook is threaded into the connecting hole. The end of the hook is provided with a lifting ring.

[0013] Preferably, one end of the rope loop is provided with a connecting buckle, which is engaged with the hanging ring, and the other end of the hanging ring is connected to the hook through a nylon corner buckle.

[0014] Preferably, the hook includes a hook body, which is specifically U-shaped, and an anti-detachment baffle is rotatably connected to one side of the hook body port. The anti-detachment baffle is used to close the port of the hook body.

[0016] Compared to the aforementioned background technology, the portable live-line working auxiliary device provided by this utility model includes: an I-shaped support plate; a first wire pressing assembly and a second wire pressing assembly are respectively provided on both sides of the vertical plate of the support plate; a pushing assembly is connected between the first wire pressing assembly, the second wire pressing assembly and the first horizontal plate of the support plate; the pushing assembly can slide within the first horizontal plate; the end of the pushing assembly abuts against one side of the first wire pressing assembly and the second wire pressing assembly; the feeding direction of the pushing assembly is parallel to the vertical plate; the pushing assembly is used to drive the first wire pressing assembly and the second wire pressing assembly to press the internal lead wires; and a rope loop is threaded through the side wall of the support plate, the rope loop connecting the support plate and the hook. The hook is attached to the main line. When applying for electrical maintenance work, the worker attaches the hook to the main line to complete the initial positioning of the support plate. The operator can then use both hands to turn and push the component to connect the lead wire to the first clamping component and the main line to the second clamping component. At this time, the relative positions of the lead wire and the main line are locked. The worker can then continue to connect the lead wire and the main line. Since the main line and the lead wire are fixed by the first clamping component and the second clamping component, the worker does not need to hold the lead wire while connecting it, which avoids the worker's body from entering the circuit and reduces the safety hazards of electrical maintenance work.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] This utility model provides a portable live-line working auxiliary device; please refer to the appendix of the instruction manual. Figure 1 This application includes a support plate 1, specifically an I-shaped support plate. A first wire pressing assembly and a second wire pressing assembly are respectively provided on both sides of the vertical plate of the support plate 1. The first and second wire pressing assemblies are located between the first and second horizontal plates of the support plate 1. A pushing assembly is connected between the first and second wire pressing assemblies and the first horizontal plate. The pushing assembly can slide within the first horizontal plate. Preferably, the feeding direction of the pushing assembly is parallel to the vertical plate. The first and second wire pressing assemblies are used to clamp the lead wire and the main guide wire. Furthermore, a rope loop 12 is threaded through the support plate 1. The two ends of the rope loop 12 are respectively connected to the support plate 1 and a hook 14. The hook 14 is used to hook onto the main guide wire. In one embodiment of this application, the worker hooks the hook 14 onto the main guide wire, and the rope loop 12 connected to the hook 14 pulls the support plate 1. The position of the support plate 1 is fixed, so the worker does not need to hold the support plate 1 during subsequent work. Then, the worker places the lead wire to be connected into the first pressure assembly, and then screws the push assembly corresponding to the first pressure assembly. The push assembly holds the first pressure assembly and clamps the lead wire tightly. Next, the main wire is placed into the second pressure assembly, and the push assembly corresponding to the second pressure assembly is screwed to make the second pressure assembly clamp the main wire. At this time, the main wire and the lead wire are fixed on both sides of the vertical plate of the support plate 1, and the relative positions of the main wire and the lead wire are locked. At this time, the worker can free his / her hands to connect the lead wire and the main wire. Since the main wire and the lead wire are fixed by the first pressure assembly and the second pressure assembly, the worker does not need to hold the lead wire for a long time, reducing the contact time between the worker and the high voltage current and reducing the incidence of safety accidents.

[0024] Furthermore, both the first and second pressure components include a first pressing block 2 and a second pressing block 3 that are symmetrical to each other. The first pressing block 2 and the second pressing block 3 are arranged along the length of the vertical plate. Preferably, curved grooves are provided on the opposite side walls of the first pressing block 2 and the second pressing block 3. When the first pressing block 2 and the second pressing block 3 are connected to each other, each curved groove provides a certain space for the lead wire and the main wire, so as to avoid the lead wire or the main wire being excessively squeezed.

[0025] Please refer to the instruction manual appendix. Figure 1 The bearing plate 1 encloses two parallel horizontal plates, a first horizontal plate and a second horizontal plate. A vertical plate is vertically disposed between the first and second horizontal plates. Preferably, a vertical pushing assembly is provided on the first horizontal plate. The pushing assembly includes a pushing screw 4, which passes through the first horizontal plate. A screwing component 5 is fitted onto the end of the pushing screw 4 facing away from the second horizontal plate. The screwing component 5 is threadedly connected to the pushing screw 4. In addition, a fixed shaft 6 passes through the second horizontal plate. The fixed shaft 6 can rotate within the second horizontal plate. One end of the fixed shaft 6 is connected to the second clamping block 3, and the other end of the fixed shaft 6 passes through... The second horizontal plate is connected to the push-pull clamping device 17, which is fixed to the side wall of the second horizontal plate. The push-pull clamping device 17 consists of a base screw, an operating handle, a fixing sleeve, and other components. The fixing sleeve is fixedly connected to the second horizontal plate. The operating handle can swing vertically at the end of the base screw. By moving the operating handle, the drive generated by the push-pull action is converted into the mechanical movement of the base screw in the vertical direction, which drives the clamping component to move. When the clamping component reaches the closed position, the linkage mechanism enters the dead point state and forms a self-locking mechanism, which can maintain stable clamping without continuous force.

[0026] When the operator fixes the lead wire and the main wire, the lead wire and the main wire are placed between the first clamping block 2 and the second clamping block 3. Then, the second clamping block 3 is rotated to adjust the setting angle of the lead wire or the main wire. After the angle adjustment is completed, the operating handle is turned to lock the fixing shaft 6. The position of the second clamping block 3 connected to the end of the fixing shaft 6 is locked. The screwing part 5 is turned. Since the end face of the screwing part 5 abuts against the first horizontal plate, the position of the screwing part 5 is locked after the screwing part 5 is rotated. The driving force generated by the screwing part 5 drives the push screw 4 to rotate. Since the push screw 4 is threadedly connected to the first horizontal plate, the rotating push screw 4 moves to the side closer to the second horizontal plate. The distance between the first clamping block 2 and the second clamping block 3 gradually decreases. The first clamping block 2 and the second clamping block 3 clamp the lead wire and the main wire, thus completing the position locking of the lead wire and the main wire.

[0027] Preferably, the screwing component 5 is a butterfly bolt. The butterfly bolt has two wing plates on the side away from the first horizontal plate. The operator can rotate the screwing component 5 by moving the wing plates, making the clamping operation between the lead wire and the main line easier.

[0028] It should be noted that when clamping the lead wire and the main guide wire, the position of the second clamping block 3 is locked, and the first clamping block 2 gradually moves closer to the second clamping block 3. When the first clamping block 2 abuts against the side wall of the first horizontal plate, the distance between the first clamping block 2 and the second clamping block 3 is at its maximum. Furthermore, an adjusting nut 7 is sleeved on one end of the fixed shaft 6 used to connect the second clamping block 3. Rotating the adjusting nut 7 allows it to slide along the axial direction of the fixed shaft 6, and the adjusting nut 7 abuts against the second clamping block 3. By adjusting the adjusting nut 7, the height of the second clamping block 3 is adjusted, changing the maximum distance between the curved grooves of the first clamping block 2 and the second clamping block 3, thus changing the maximum size of the wire clamped by both. Preferably, several stop marks 16 are provided on the side wall of the vertical plate. When adjusting the setting height of the second clamping block 3 by adjusting the adjusting nut 7, the operator can use each stop mark 16 as a reference to adjust the second clamping block 3. The upper surface of the clamping block 3 corresponds to the stop marks 16 at different heights. Preferably, there are three stop marks 16, which are respectively called the first mark, the second mark, and the third mark. Each mark is distributed sequentially towards the side closest to the first horizontal plate. When the upper surface of the second clamping block 3 corresponds to the first mark, the first and second wire clamping components are suitable for wires with a cross-sectional area of ​​70 square millimeters. When it corresponds to the second mark, it is suitable for wires with a cross-sectional area of ​​150 square millimeters. When it corresponds to the third mark, it is suitable for wires with a cross-sectional area of ​​240 square millimeters. By setting the stop marks 16, the operator can visually estimate the size of the wire in advance and adjust the height of the second clamping block 3 with the stop marks 16 as a reference. The first and second wire clamping components are adjusted to adapt to the current size of the lead wire and the main wire, ensuring that the lead wire and the main wire can be stably clamped.

[0029] In addition, a first locking hole 9 and a second locking hole 10 are respectively provided on the side walls of the first clamping block 2 and the second clamping block 3. The first locking hole 9 and the second locking hole 10 extend to the push screw 4 and the fixed shaft 6 respectively. Locking members are threaded into the first locking hole 9 and the second locking hole 10. When the locking members are screwed on, the locking members gradually extend into the first locking hole 9 and the second locking hole 10. The end of the locking member abuts against the side walls of the push screw 4 and the fixed shaft 6. Each locking member is used to lock the relative position of the first clamping block 2 and the push screw 4, and the second clamping block 3 and the fixed shaft 6, so as to prevent the push screw 4 or the fixed shaft 6 from loosening, which would cause the lead wire and the main guide wire to be unable to be stably clamped.

[0030] Please continue to refer to the instruction manual appendix. Figure 1 and 2A connecting hole 8 is provided on the side wall of the second horizontal plate. A hook 11 is fixed in the connecting hole 8. A hanging ring is provided at the end of the hook 11. The hanging ring is hooked to the connecting buckle 18 of the rope loop 12. The other end of the rope loop 12 is connected to the hook 14 through the nylon corner buckle 13. The rope loop 12 is sleeved on the outside of the nylon corner buckle 13 to reduce the wear of the rope loop 12 during operation. The hook 14 fixes the bearing plate 1 to the main line. Preferably, an anti-detachment baffle 15 is rotatably connected to one side of the hook 14. A spring is connected between the anti-detachment baffle 15 and the hook 14. The anti-detachment baffle 15 is used to close the port of the hook body. When the worker abuts the anti-detachment baffle 15 through the main line, the anti-detachment baffle 15 rotates around the spring at a certain angle to open the opening of the main line. When the main line is inserted into the hook 14, the compressed spring drives the anti-detachment baffle 15 to rebound and close the port of the hook 14 again to prevent the main line from slipping out of the hook 14.

[0031] In one embodiment of this application, the worker attaches the hook 14 to the main line to initially fix the position of the support plate. Then, the worker visually assesses the size of the lead wire and the main line, and adjusts the height of the second clamping block 3 by adjusting the nut 7 so that the upper surface of the second clamping block 3 corresponds to the corresponding stop line 16. The worker places the lead wire and the main line in the curved groove of each second clamping block 3, rotates the screw 5, and pushes the screw 4 to move the first clamping block 2 closer to the end of the second clamping block 3 until each first clamping block 2 and each second clamping block 3 stably clamps the lead wire and the main line, locking the relative position of the lead wire and the main line. The worker can then free up both hands to perform subsequent splicing operations of the lead wire and the main line.

[0032] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0033] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
