Description

Technical Field

[0001] The invention relates to the technical field of power equipment maintenance tools, and in particular to a live bolt fastening device. Background Art

[0002] During the inspection and maintenance of power distribution line equipment, it was found that the 10kV straight poles were prone to vibrate due to the swinging of the conductors in the wind, which caused the foot bolts of the pole insulators to loosen. In windy weather, it was easy for the pole insulators to be pulled out of the line, resulting in the line being grounded.

[0003] However, due to the extremely high requirements for power supply reliability, the possibility of tightening an insulator foot bolt during a power outage is extremely low. The traditional process for tightening the insulator foot bolts is to manually go up the pole and tighten the insulator foot bolts with a wrench after the power outage by applying for a switching operation ticket, thereby eliminating risks. Existing tools for tightening insulator foot bolts can only be used during planned power outages for maintenance or emergency repairs, and the pressure for high-quality service is high, which cannot meet the needs of patrol personnel. Summary of the invention

[0004] The present invention provides a device for fastening bolts under power, which aims to facilitate workers to fasten bolts under power while standing underground or on a ladder after finding that the bolts are loose during inspection, thereby improving line reliability and safe and stable operation capability.

[0005] The present invention is achieved through the following technical scheme: a live bolt tightening device, including a socket wrench, a main insulating rod and a connecting unit, the main insulating rod and the socket wrench are connected through the connecting unit; the connecting unit includes a mounting member and a connecting member, one end of the mounting member is connected to the socket wrench, a through hole is opened on the mounting member, a rotating shaft is provided in the through hole, the rotating shaft is rotatably connected to the connecting member, and one end of the connecting member away from the mounting member is connected to the main insulating rod.

[0006] Compared with the prior art, this solution has the following advantages and beneficial effects:

[0007] In this solution, the main insulating rod is combined with a socket wrench. The main insulating rod has insulating properties. When the staff finds that the bolts are loose during inspection, they can stand underground or on a ladder to tighten them live, which improves the reliability of the line and the ability to operate safely and stably. It effectively solves the trouble of traditional power outage operation when tightening insulator bolts. This solution is more efficient and convenient for live processing, greatly compresses the links and time of power outage processing, and effectively improves maintenance efficiency.

[0008] In addition, in the present embodiment, the connecting unit is used to connect the main insulating rod and the socket wrench, and the connection between the socket wrench and the main insulating rod is realized through the mounting member and the connecting member in the connecting unit. At the same time, a rotating shaft is provided in the through hole of the mounting member, and the rotating shaft is rotatably connected to both sides of the connecting member, so that the rotating shaft connects the mounting member and the connecting member.

[0009] At the same time, since the rotating shaft is rotatably connected to both sides of the connecting piece, the socket wrench connected to the mounting piece can rotate along the rotating shaft. When the operator holds the main insulating rod and puts the socket wrench on the bolt, it is more flexible and will not be limited to a fixed direction. In addition, when there are other interferences such as power accessories next to the base bolt that hinder the position of the main insulating rod, the main insulating rod can be offset by a certain distance to avoid the interference, and the socket wrench can still be aligned with the bolt and tighten the bolt. The live bolt tightening device in this scheme has a wide range of applications and can be used in various working conditions and environments. It can avoid obstacles to tighten the bolts, and when tightening the bolts, it will not be limited to a fixed position, and it is more flexible and convenient to use.

[0010] The live bolt fastening device in this solution can realize non-power-off operation, effectively shortening the work links, especially the accident emergency repair list, instruction book and safety briefing materials, power outage safety measures and other links, saving a lot of time and improving work efficiency, and reducing the risk of quality service complaints caused by power outages. In addition, the live bolt fastening device in this solution only requires one person to implement the operation, and is easy to operate.

[0011] Furthermore, a slider and a swing block are also provided in the through hole, the slider is axially slidably matched with the rotating shaft, one side of the swing block is clamped on the mounting member, and the other side of the swing block is slidably matched with one side of the slider, and the side of the swing block sliding with the slider is an arc-shaped surface, and the slider is provided with an arc-shaped groove slidably matched with the swing block.

[0012] Beneficial effect: The arrangement of the slider and the swing block in the present solution further increases the freedom of movement of the socket wrench. The slider can slide along the rotating shaft, and the swing block can swing along the arc of the slider. In this way, the socket wrench can rotate along the rotating shaft, slide along the axial direction of the rotating shaft, and swing along the axial direction of the rotating shaft. In this way, when tightening the bolts, the position requirements for the operator are lower. The live bolt tightening device of the present application can adapt to various complex or simple environments when repairing high-voltage distribution line equipment.

[0013] Furthermore, a slide groove is provided on one side of the slider away from the swing block, the slide groove is a through groove structure, and the shape of the slide groove matches the shape of the rotating shaft, and a clamping groove is provided on one side of the swing block, and the clamping groove can be clamped on one side of the through hole.

[0014] Beneficial effect: The shape of the slide groove in this solution matches the shape of the rotating shaft, which can improve the matching accuracy and stability between the slider and the rotating shaft, and the card slot set on the swing block is convenient for being stuck on one side of the through hole, so as to achieve connection and matching with the mounting piece, which is convenient for driving the mounting piece and the socket wrench connected to the mounting piece to make corresponding movements.

[0015] Furthermore, the through hole includes a circular hole and a square hole, the circular hole and the square hole are interconnected, the rotating shaft is cylindrical, the rotating shaft is located in the circular hole and can rotate in the circular hole, and the slider and the swing block are located in the square hole.

[0016] Beneficial effects: In this solution, the round hole is convenient for rotating with the rotating shaft, while the square hole is convenient for installing the slider and the swing block, and can limit the position of the swing block and the slider, so that the installation and matching accuracy of the slider and the swing block is higher.

[0017] Furthermore, there are two mounting members, and the two mounting members are symmetrically arranged, and there are two connecting members, and the two connecting members are symmetrically arranged, and the two ends of the rotating shaft are rotatably connected to the two connecting members respectively.

[0018] Beneficial effects: In this solution, two mounting parts and two connecting parts are provided, which can improve the strength and stability of the entire connecting unit.

[0019] Furthermore, the mounting member includes an upper section, a middle section and a lower section, the upper section and the lower section are arranged parallel to each other, the middle section is arranged obliquely, and both ends of the middle section are respectively connected to the upper section and the lower section.

[0020] Beneficial effect: The positional relationship between the upper, middle and lower sections of the mounting piece in this solution, as well as the inclined state of the middle section, allows the two mounting pieces to be symmetrically arranged to form a triangle-like shape, which can improve the connection stability and strength of the mounting piece to the socket wrench, and when the socket wrench is used to tighten the bolt, the force effect is better, and the bolt can be tightened faster.

[0021] Furthermore, a horizontal cylinder is provided between the connecting unit and the main insulating rod, one side of the horizontal cylinder is vertically connected to a vertical cylinder in communication therewith, a first rotating rod is rotatably connected in the horizontal cylinder, one end of the first rotating rod is connected to the connecting unit, the other end of the first rotating rod is connected to the main insulating rod, and a first bevel gear is coaxially connected to the first rotating rod;

[0022] A second rotating rod is rotatably connected in the vertical cylinder, a second bevel gear is connected to the second rotating rod, and the first bevel gear and the second bevel gear are meshed with each other; one end of the second rotating rod is connected to a secondary insulating rod.

[0023] Beneficial effect: In the present scheme, the first rotating rod and the second rotating rod are linked by the first bevel gear and the second bevel gear, so that when in use, it is convenient to tighten the bolts in different positions and directions. When tightening the bolts located vertically, the main insulating rod can be held and rotated to drive the socket wrench to rotate and tighten the bolts. For the bolts arranged laterally, when in use, the secondary insulating rod can be held and rotated to rotate the secondary insulating rod to rotate the second rotating rod and drive the first rotating rod to rotate, thereby driving the socket wrench to rotate and tighten the bolts. Of course, the main insulating rod can also be directly rotated to drive the first rotating rod and the socket wrench to rotate. The user can flexibly choose to rotate the main insulating rod or the secondary insulating rod according to the actual operation position.

[0024] In this solution, the main insulating rod and the auxiliary insulating rod can realize the tightening of the bolt in different directions, which is flexible and convenient to use. In addition, when the L-shaped wrench in the prior art is used to tighten the bolt, it is necessary to rotate the rod of the entire wrench along the circumference of the wrench. If the rod is long, a large space is required to smoothly rotate the rod. However, in this application, the auxiliary insulating rod and the socket wrench form an L-shaped wrench. When it is used, it is not necessary to rotate the auxiliary insulating rod along the circumference of the socket wrench. It is only necessary to rotate the auxiliary insulating rod to transmit the force to the socket wrench through the bevel gear. In this way, when the length of the auxiliary insulating rod is extended, the required rotation space does not need to be increased accordingly. In this way, the device of this solution has low requirements on the use environment, is easy to operate, and is more practical.

[0025] Furthermore, the main insulating rod and the auxiliary insulating rod are both telescopic rods.

[0026] Beneficial effects: In this solution, both the main insulating rod and the auxiliary insulating rod can be shortened or extended in length, so as to adapt to different maintenance height requirements encountered in actual work, and the solution is more practical.

[0027] Furthermore, the main insulating rod is a telescopic rod.

[0028] Beneficial effect: With such arrangement, the main insulating rod can be extended or shortened according to different needs, thereby adapting to different maintenance heights.

[0029] Furthermore, an anti-slip unit is provided on the main insulating rod.

[0030] Beneficial effect: This can prevent hands from slipping when tightening bolts. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] like Figure 1 As shown, this embodiment provides a live bolt fastening device, including a socket wrench 1, a main insulating rod 3 and a connecting unit, wherein the main insulating rod 3 and the socket wrench 1 are connected via the connecting unit; Figure 2 As shown, in this embodiment, the connecting unit includes a mounting member 11 and a connecting member 12. One end of the mounting member 11 is connected to the socket wrench 1. The mounting member 11 and the socket wrench 1 can be connected by welding, bonding, bolting, etc.

[0043] Combination Figure 2 and Figure 3 As shown, a through hole 110 is opened on the mounting member 11, and a rotating shaft 13 is arranged in the through hole 110. The rotating shaft 13 is rotatably connected to the connecting member 12. The end of the connecting member 12 away from the mounting member 11 is connected to the main insulating rod 3. The connecting member 12 and the main insulating rod 3 can be connected by bolt connection, welding, bonding or threaded connection.

[0044] The main insulating rod 3 can be a rod of fixed length or a rod whose length can be adjusted. In this embodiment, the main insulating rod 3 is a telescopic rod structure, which can be applied to operating environments of different height distances and is more practical. An anti-skid unit is provided on the main insulating rod 3. The anti-skid unit is arranged on the outside of the main insulating rod 3 and located at the tail of the main insulating rod 3 (i.e., the side away from the socket wrench 1). The anti-skid unit can be an anti-skid sleeve 4 with an anti-skid function or an anti-skid pattern directly processed on the main insulating rod 3.

[0045] like Figure 2 and Figure 4 As shown, in another embodiment, a slider 14 and a swing block 15 are further provided in the through hole 110, the slider 14 is axially slidably matched with the rotating shaft 13, one side of the swing block 15 is clamped on the mounting member 11, and the other side of the swing block 15 is slidably matched with one side of the slider 14, and the side where the swing block 15 slides with the slider 14 is an arc surface, and the slider 14 is provided with an arc groove that is slidably matched with the swing block 15. Specifically: Figure 3 As shown, the through hole 110 includes a circular hole 1101 and a square hole 1102, the circular hole 1101 and the square hole 1102 are interconnected, the rotating shaft 13 is cylindrical, the rotating shaft 13 is located in the circular hole 1101 and can rotate in the circular hole 1101, the slider 14 and the swing block 15 are located in the square hole 1102, and the slider 14 is a rectangular block.

[0046] Recombination Figure 2 and 4 As shown, a slide groove 1401 is provided on the side of the slider 14 away from the swing block 15, and the slide groove 1401 is a through groove structure, and the shape of the slide groove 1401 matches the shape of the rotating shaft 13, that is, the slide groove 1401 is an arc-shaped slide groove, and a clamping groove 1501 is provided on one side of the swing block 15, and the clamping groove 1501 can be clamped on one side of the through hole 110. In this embodiment, the clamping groove 1501 is in the shape of a rectangular clamping groove.

[0047] Combination Figure 2As shown, there are two mounting members 11, and the two mounting members 11 are symmetrically arranged. There are two connecting members 12, and the two connecting members 12 are symmetrically arranged. Specifically, the mounting member 11 includes an upper section, a middle section and a lower section. The upper section and the lower section are arranged parallel to each other, the middle section is arranged obliquely, and the two ends of the middle section are respectively connected to the upper section and the lower section. The upper section is located above the lower section, and the end of the upper section away from the middle section is connected to the socket wrench 1. The two ends of the rotating shaft 13 are respectively rotatably connected to the two connecting members 12. In this embodiment, both ends of the rotating shaft 13 extend out of the through hole 110 and are respectively rotatably connected to the inner side of the two connecting members 12. In order to facilitate the connection with the main insulating rod 3, in this embodiment, a connecting plate is vertically connected to the end of the two connecting members 12 away from the mounting member 11. The two connecting members 12 are connected into one body through a vertically arranged connecting plate, and the two connecting members 12 are connected to the main insulating rod 3 through the connecting plate.

[0048] The specific implementation process is as follows: the main insulating rod 3 is made of insulating material, so it can work with electricity, and the socket wrench 1 can be a specific type of wrench. At this time, the socket wrench 1 can be designed to be detachably connected to the mounting member 11, such as fixing the socket wrench 1 to the mounting member 11 by bolts, so that it is convenient to replace other types of socket wrenches 1 after later disassembly. Of course, the socket wrench 1 can also use the magic socket wrench 1 or the universal socket wrench 1 in the prior art, which can be suitable for different types of bolts, such as using the wrench recorded in the existing patent publication number CN205465890U.

[0049] In actual use, due to the design of the rotating shaft 13, the slider 14 and the swing block 15 in the utility model, the rotating shaft 13 can make the socket wrench 1 generate rotational motion along the rotating shaft 13, and due to the setting of the swing block 15 and the slider 14, the swing block 15 connects one end of the two mounting parts 11 into one, so the socket wrench 1 can slide back and forth along the axial direction of the rotating shaft 13 under the action of the slider 14; in addition, due to the arc sliding design between the swing block 15 and the slider 14, the socket wrench 1 can swing along the upper and lower ends of the rotating shaft 13, so that the socket wrench 1 can perform adaptive motion in multiple dimensional spaces. When the operator needs to tighten and fix the bolts during the maintenance process, the socket wrench 1 can be appropriately adjusted in position after being put on the bolts to be tightened. When tightening the bolts, the part will not be limited to a fixed position, and the use is more flexible and convenient, which has lower requirements on the operating position of the operator. When the high-voltage distribution line equipment is repaired, the bolt live tightening device of the utility model can adapt to various complex or simple environments.

[0050] like Figure 5 and Figure 6As shown, in another embodiment, a horizontal cylinder 2 is further provided between the connecting unit and the main insulating rod 3, and a vertical cylinder 6 which is in communication with the horizontal cylinder 2 is vertically connected to one side of the horizontal cylinder 2. In this embodiment, the vertical cylinder 6 and the horizontal cylinder 2 are integrally formed, and a first rotating rod 7 is rotatably connected in the horizontal cylinder 2. One end of the first rotating rod 7 is connected to the connecting unit, and the other end of the first rotating rod 7 is connected to the main insulating rod 3. In this embodiment, the connecting unit is indirectly connected to the main insulating rod 3 via the first rotating rod 7. When the main insulating rod 3 is rotated, the connecting unit and the socket wrench 1 connected to the connecting unit can be driven to rotate, thereby achieving the purpose of tightening the bolts.

[0051] The first rotating rod 7 is coaxially connected to the first bevel gear 8; the second rotating rod 9 is rotatably connected in the vertical tube 6, and the second rotating rod 9 is connected to the second bevel gear 10, and the first bevel gear 8 and the second bevel gear 10 are meshed with each other; the second rotating rod 9 is connected to the auxiliary insulating rod 5 at one end away from the first rotating rod 7, so that the auxiliary insulating rod 5 and the main insulating rod 3 are perpendicular to each other. In this embodiment, the main insulating rod 3 and the auxiliary insulating rod 5 are telescopic rods, which can be extended or shortened according to actual needs, and the main insulating rod 3 and the auxiliary insulating rod 5 are both provided with anti-skid units, and the setting of the anti-skid units is the same as that of the above embodiment, which will not be repeated here.

[0052] In this embodiment, the secondary insulating rod 5 and the socket wrench 1 form an L-shaped structure, and the main insulating rod 3 and the socket wrench 1 form a straight structure. The secondary insulating rod 5 and the main insulating rod 3 can be used by operators to tighten bolts in different directions at the same position (such as underground), for example, they can be used to tighten bolts in vertical and lateral directions.

[0053] When tightening the bolts located laterally, you can also stand on the ground and use the L-shaped structure formed by the auxiliary insulating rod 5 and the socket wrench 1 to tighten them. By rotating the auxiliary insulating rod 5, the first bevel gear 8 drives the second bevel gear 10 to rotate, thereby driving the first rotating rod 7, the connecting unit and the socket wrench 1 to rotate and tighten the bolts. The operation is convenient and simple, and the requirements for the operating position are low. When tightening the vertically arranged bolts, the main insulating rod 3 and the socket wrench 1 can be used to form a straight-line structure. By rotating the main insulating rod 3, the socket wrench 1 can be driven to rotate and tighten the bolts.
