Description

Technical Field

[0001] The present application relates to the field of power maintenance operations, and in particular to a device for live working and an operating method. Background Art

[0002] In the power system, it is often necessary to inspect and repair insulator strings. To inspect tower equipment, it is necessary to climb up the tower to perform high-altitude work. However, the tower is too high and without perfect safety protection measures, high-altitude work will bring great danger to construction workers.

[0003] Reference Figure 1 In the related art, the electric tower 6 and the insulator string 61 are connected through a connecting fitting 62 and a triangular connecting plate 63. One end of the connecting fitting 62 is connected to the electric tower 6 and the other end is connected to the triangular connecting plate 63. The insulator string 61 is connected to the triangular connecting plate 63. When inspecting the insulator string 61, the staff needs to walk from the electric tower 6 to the triangular connecting plate 63 through the connecting fitting 62.

[0004] Currently, before construction, the staff will first throw a connecting belt with a hook to the triangular connecting plate 63, then tighten the connecting belt, and fix the other end of the connecting belt on the power tower 6. Then, the staff can help the connecting belt walk from the power tower 6 to the triangular connecting plate 63.

[0005] With respect to the above-mentioned related technologies, the inventors believe that directly throwing the hook toward the triangular connecting plate may not allow the hook to be accurately hooked on the triangular connecting plate, and sometimes multiple attempts are required, which is time-consuming and labor-intensive, and increases the difficulty of high-altitude operations.

[0031] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in some embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present disclosure.

[0032] Unless the context requires otherwise, throughout the specification and claims, the term "including" is to be interpreted as an open, inclusive meaning, that is, "including, but not limited to".

The schematic representations of the above terms do not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials or characteristics described may be included in any one or more embodiments or examples in any appropriate manner.

[0033] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0034] The embodiment of the present invention provides a device for live working, comprising: an auxiliary insulating rod and a hook, referring to Figure 2 , Figure 3 and Figure 4 The auxiliary insulating rod comprises: a telescopic rod 1, and a connecting ring 2 arranged at one end of the telescopic rod 1; Figure 5 The hook comprises: a hook body 3 and a connecting belt 5 connected to each other; a connecting ring 2 cooperates with the hook body 3, and the telescopic rod 1 is extended to deliver the hook body 3 to the triangular connecting plate 63 for hooking.

[0035] In some embodiments, reference Figure 4 The connecting ring 2 includes a first ring segment 21 and a second ring segment 22, both of which are arc-shaped semicircular rings. One end of the first ring segment 21 is rotatably connected to one end of the second ring segment 22, and the first ring segment 21 and the second ring segment 22 are elastically connected, and the first ring segment 21 and the second ring segment 22 tend to move closer to each other.

[0036] For example, refer to Figure 4One end of the first ring segment 21 is hinged to one end of the second ring segment 22, and the first ring segment 21 and the second ring segment 22 are elastically connected by a spring, and the spring is in a contracted state. Therefore, in a normal state, under the action of the elastic force, the first ring segment 21 and the second ring segment 22 tend to move closer to each other.

[0037] In a normal state, the connecting ring 2 is in a closed state, at which point the end of the first ring segment 21 away from the hinged end and the end of the second ring segment 22 away from the hinged end abut against each other; when the first ring segment 21 and the second ring segment 22 are subjected to force, the first ring segment 21 and the second ring segment 22 move away from each other, at which point there is a gap between the end of the first ring segment 21 away from the hinged end and the end of the second ring segment 22 away from the hinged end, the connecting ring 2 forms an opening, and the opening direction of the connecting ring 2 is not in the same direction as the length direction of the telescopic rod 1.

[0038] In this embodiment, the opening direction of the connecting ring 2 is perpendicular to the length direction of the telescopic rod 1. In other embodiments, the angle between the opening direction of the connecting ring 2 and the length direction of the telescopic rod 1 can be 120°, 135°, etc.

[0039] The present invention provides a device for live working, wherein the telescopic rod enables the auxiliary insulating rod to have a telescopic function, and when being carried, the auxiliary insulating rod can be retracted, which is convenient for carrying the auxiliary insulating rod and reduces the inconvenience caused by people carrying the auxiliary insulating rod; when in use, the auxiliary insulating rod can be extended, which is convenient for hanging a hook body on a triangular connecting plate; a connecting ring is convenient for connecting with the hook body, and when connected, the first ring segment and the second ring segment are opened, the hook body is placed between the first ring segment and the second ring segment, and then the hook body is sent to the triangular connecting plate through the telescopic rod to be hung tightly; when the auxiliary insulating rod needs to be retracted, only the telescopic rod needs to be pulled, the connecting ring is forced to open, and the connecting ring can be removed from the hook body by a slight movement; the embodiment provided by the present invention makes the connection and separation of the connecting ring and the hook body more convenient and quick, and the hook body is sent to the triangular connecting plate to be hooked through the auxiliary insulating rod, which is convenient for accurately hooking the hook on the triangular connecting plate.

[0040] If the opening direction of the connecting ring is consistent with the length direction of the telescopic rod, when the hook body is sent to the triangular connecting plate for hooking through the telescopic rod, the hook body is located in the direction of the opening of the connecting ring. Since the telescopic rod needs to be pulled hard to hang the hook body tightly, the hook body may be separated from the connecting ring at the opening. Therefore, the opening is set at other positions of the connecting ring. When pulling hard, the hook body is not easy to be separated from the connecting ring, which facilitates the connection between the hook body and the triangular connecting plate.

[0041] By adopting the above technical solution, when the hook body is hung on the triangular connecting plate through the auxiliary insulating rod, the end of the connecting belt away from the hook body is tied to the electric tower, and the connecting belt is tied and tightened to make the connecting belt in a taut state. At this time, the connecting belt can be passed through the connecting hardware by hand, reducing the possibility of maintenance personnel falling from the connecting hardware; at the same time, when the hook body needs to be retracted, the hook body can be retracted through the connecting belt, which makes it easy for the hook body to be reused.

[0042] In some embodiments, reference Figure 2 The telescopic rod 1 includes: a plurality of straight tubes 11 and a fixing assembly 12 , and two adjacent straight tubes 11 are connected by the fixing assembly 12 .

[0043] In some examples, reference Figure 2 The diameters of the plurality of straight tubes 11 gradually decrease, and the straight tube 11 with a larger diameter is sleeved outside the straight tube 11 with a smaller diameter among two adjacent straight tubes 11, and the two adjacent straight tubes 11 are slidably connected to each other. In this way, the telescopic function of the telescopic rod 1 can be realized, and it is convenient for application.

[0044] In some examples, reference Figure 2 A cylindrical base 112 is welded to the port of one end of the straight tube 11 with the largest diameter. In this way, the base 112 can block the port of the straight tube 11 with the largest diameter, preventing the remaining straight tubes 11 from sliding out of the port of the straight tube 11 with the largest diameter. At the same time, the base 112 is heavy, which can play a role of gravity balance when the telescopic rod 1 is used, making it convenient for maintenance personnel to hold the telescopic rod 1 for operation.

[0045] In some examples, reference Figure 2 The first ring segment 21 is welded to an end of the straight tube 11 with the smallest diameter in the telescopic rod 1 that is away from the base 112 .

[0046] In some examples, reference Figure 2 Two handles 113 are provided on the straight tube 11 with the largest diameter.

[0047] Exemplarily, the handle 113 may be made of rubber and provided with anti-skid grooves. In other embodiments, the handle 113 may also be made of sponge. The handle 113 is used for holding by a human hand, so that maintenance personnel can perform hand-held operation.

[0048] In some embodiments, reference Figure 3The fixing component 12 includes a clamping ring 121 and an abutment ring 122. The clamping ring 121 is coaxially welded to the port of the straight pipe 11 with the fixing component 12 away from the base 112. The inner diameter of the clamping ring 121 is the same as the inner diameter of the straight pipe 11 connected to the clamping ring 121, and the outer diameter of the larger end of the port of the clamping ring 121 is the same as the outer diameter of the straight pipe 11 connected to the clamping ring 121. The clamping ring 121 is a truncated cone-shaped ring; the abutment ring 122 is a columnar ring, which can be sleeved on the outside of the clamping ring 121 and plays a role of fixed connection through the clamping ring 121.

[0049] In some examples, reference Figure 3 The clamping ring 121 is provided with a plurality of slits 1211, the length direction of the slits 1211 is consistent with the axial direction of the clamping ring 121, and the plurality of slits 1211 are evenly distributed along the circumference of the clamping ring 121. In this way, when the outer diameter of the clamping ring 121 is subjected to external force, the clamping ring 121 can be locked through the plurality of slits 1211, so that the fixing assembly 12 can fix the two adjacent straight pipes 11.

[0050] In some examples, reference Figure 3 A tightening ring 1221 is coaxially connected to the inner wall of one end of the abutment ring 122. The tightening ring 1221 is sleeved outside the clamping ring 121. The inner diameter of the tightening ring 1221 is smaller than the outer diameter of the larger end of the clamping ring 121 port and larger than the outer diameter of the smaller end of the clamping ring 121 port. The abutment ring 122 provides force to the clamping ring 121 through the tightening ring 1221, thereby locking the clamping ring 121 to play a role of fixed connection.

[0051] In some examples, except for the straight tube 11 with the smallest diameter, each of the other straight tubes 11 is provided with a fixing component 12 , and the size of the fixing component 12 can be changed with the size of the straight tube 11 .

[0052] The abutment ring 122 is threadedly connected to the straight tube 11. When the abutment ring 122 is tightened, the inner wall of the tightening ring 1221 abuts against the peripheral wall of the clamping ring 121. At this time, the inner wall of the clamping ring 121 abuts against the peripheral wall of the straight tube 11 passing through the clamping ring 121, thereby fixing the straight tube 11 passing through the clamping ring 121, thereby achieving fixation between two adjacent straight tubes 11.

[0053] By connecting a plurality of straight tubes 11 to each other through the above method, in this embodiment, the length of the telescopic rod 1 in the retracted state can reach 50 centimeters, and the length of the telescopic rod 1 in the extended state can reach three meters.

[0054] In some embodiments, the fixing assembly 12 also includes a top screw and a handle. The top screw is rotatably connected to the straight tube 11. The top screw is used to abut against the small-diameter straight tube 11 inside the straight tube 11 connected to the top screw. The handle is connected to the top screw, and the handle facilitates the staff to rotate the top screw.

[0055] The working principle of the above-mentioned auxiliary insulating rod is as follows: when it is necessary to extend or shorten the telescopic rod 1, loosen the abutment ring 122, and the straight tube 11 with a smaller diameter can slide freely in the straight tube 11 with a larger diameter; when it is necessary to limit the sliding of the straight tube 11 in the telescopic rod 1, rotate the abutment ring 122 to a locked state, and the abutment ring 122 moves with the tightening ring 1221 toward the side close to the large end of the clamping ring 121, and the tightening ring 1221 abuts against the clamping ring 121, and the clamping ring 121 abuts against the wall of the straight tube 11. At this time, the movement of the straight tube 11 is restricted and the sliding stops; the connecting ring 2 is in a closed state under normal conditions and can be opened after being subjected to force.

[0056] In some embodiments, reference Figure 5 The hook body 3 is a metal hook painted with insulating paint. The hook body 3 includes a first hook segment 31, a hook segment 32 and a second hook segment 33. The hook segment 32 is in a semicircular arc shape. The first hook segment 31 and the second hook segment 33 are both in the shape of long strips. The length of the first hook segment 31 is longer than that of the second hook segment 33. One end of the hook segment 32 is integrally connected to the first hook segment 31, and the other end is integrally connected to the second hook segment 33. A hook groove is formed on the inner side of the hook body 3. The hook groove is surrounded by the first hook segment 31, the hook segment 32 and the second hook segment 33. The concave wall of the hook segment 32 close to the hook groove is the bottom wall of the hook groove surrounded by the hook body 3.

[0057] In some embodiments, reference Figure 5 , Figure 6 and Figure 7 The hook further comprises: a clamping member 4, the hook body 3 passes through the clamping member 4 and is rotatably connected to the clamping member 4, one end of the clamping member 4 is connected to the connecting belt 5, and the other end extends in a direction away from the inner side of the hook groove of the hook body 3.

[0058] In some examples, reference Figure 5 , Figure 6 and Figure 7 The clamping member 4 is in the shape of a long strip, and a long strip movable hole 41 is opened on the clamping member 4. The length direction of the movable hole 41 is consistent with the length direction of the clamping member 4. The first hook segment 31 passes through the movable hole 41, and the first hook segment 31 and the clamping member 4 are rotatably connected through the shaft hole clearance fit; one end of the clamping member 4 is located on the side of the first hook segment 31 away from the second hook segment 33, and the other end extends in the direction away from the inner side of the hook groove of the hook body 3.

[0059] In some examples, reference Figure 5 , Figure 6 and Figure 7The intersection of the hook body 3 and the clamping member 4 is a rotation connection point, and the rotation connection point is located between the two ends of the clamping member 4; one end of the clamping member 4 connected to the connecting belt 5 is elastically connected to the hook body 3.

[0060] For example, refer to Figure 5 , Figure 6 and Figure 7 The end of the clamping member 4 outside the hook groove is elastically connected to the end of the first hook section 31 near the hook section 32 through a spring, and the spring is in a contracted state. In this way, in a normal state, the end of the clamping member 4 outside the hook groove of the hook body 3 is located on the side of the rotation connection point of the clamping member 4 near the hook section 32.

[0061] In some examples, reference Figure 5 , Figure 6 and Figure 7 A transition section 42 is provided on one end of the clamping member 4 extending away from the inner side of the hook groove. One end of the transition section 42 is integrally connected with the clamping member 4 and the other end extends toward the side away from the curved hook section 32. The transition section 42 is inclined toward the side close to the first hook section 31 in the direction away from the curved hook section 32. In normal state, the end of the transition section 42 away from the clamping member 4 abuts against the side wall of the first hook section 31 close to the hook groove. In this way, the transition section 42 facilitates the triangular connecting plate 63 to smoothly enter the hook groove of the hook body 3 during the hooking process.

[0062] By adopting the above technical scheme, when only the hook body is connected to the triangular connecting plate, after the connecting belt is tightened, the connecting belt is passed by hand, and the hook body is likely to be displaced on the triangular connecting plate, which may cause the connecting belt to loosen, thereby reducing the stability of the maintenance personnel when they pass the connecting belt through the connecting hardware by hand; a clamping piece is provided, and when the connecting belt is tightened, the connecting belt will drive the clamping piece to rotate, and the end of the clamping piece away from the connecting belt will exert a force on the triangular connecting plate. The tighter the connecting belt is pulled, the tighter the triangular connecting plate is clamped by the hook body and the clamping piece, and the clamping piece makes the hook between the hook body and the triangular connecting plate more tightly, thereby reducing the possibility of displacement of the hook body on the triangular connecting plate and ensuring the safety of maintenance work.

[0063] In some embodiments, reference Figure 5 The hook further comprises a safety belt 52, one end of which is connected to the hook body 3, and the other end is connected to the connecting belt 5 by sewing. When the connecting belt 5 is in a tightened state, the safety belt 52 is in a relaxed state.

[0064] By adopting the above technical solution, since the clamping member is rotatably connected to the hook body, and the rotational connection point between the clamping member and the hook body may be aged and broken, a safety belt is provided. When the clamping member and the hook body are broken and separated, the safety belt reconnects the connecting belt and the hook body. At this time, the connecting belt is still connected between the tower and the hook body, which reduces the possibility of separation of the connecting belt and the hook body, and also reduces safety hazards, making the use of the hook safer.

[0065] In some embodiments, reference Figure 5 , Figure 6 and Figure 7 A first through hole 43 is formed on one end of the clamping member 4 away from the hook body 3 , a first movable ring 431 is hung in the first through hole 43 , and the first movable ring 431 is connected to one end of the connecting belt 5 .

[0066] In some embodiments, reference Figure 5 , Figure 6 and Figure 7 A second through hole 311 is formed on one end of the first hook section 31 away from the bent hook section 32 , and a second movable ring 3111 is hung in the second through hole 311 . The second movable ring 3111 is connected to one end of the safety belt 52 .

[0067] It should be noted that the present invention does not limit the shapes and styles of the first movable ring 431 and the second movable ring 3111. In this embodiment, the first movable ring 431 and the second movable ring 3111 are locking carabiners. In other embodiments, the first movable ring 431 and the second movable ring 3111 may be circular rings.

[0068] The first movable ring 431 and the second movable ring 3111 are convenient for adjusting the degree of torsion between the hook body 3 and the connecting belt 5 .

[0069] By adopting the above technical solution, since a wider belt is used for the connecting belt, when the hook body is sent to the triangular connecting plate, the hook body may flip over, and the connecting belt will also twist accordingly. The connecting belt is in a twisted state, which is not convenient for people to hold by hand. Therefore, a first movable ring is provided, and the first movable ring can move in the first through hole, providing a margin for the twisting of the connecting belt, reducing the twisting degree of the connecting belt, and facilitating maintenance personnel to hold the triangular connecting plate by hand through the connecting hardware. At the same time, it is also convenient to adjust the angle of the hook body when it is sent to the triangular connecting plate, so that the hook body is easy to hook. The existence of the first movable ring reduces the twisting degree of the connecting belt after it is tightened.

[0070] By adopting the above technical solution, since the safety belt is connected to the connecting belt, the twisting of the safety belt will cause the synchronous twisting of the connecting belt. At this time, holding the connecting belt by hand will cause inconvenience, so a second movable ring is provided, and the second movable ring can have a certain range of movement in the second through hole. The safety belt connected to the second movable ring also has a certain twisting range, which reduces the influence of the twisting of the safety belt on the connecting belt, making the connecting belt easier to be grasped by hand. The existence of the second movable ring reduces the degree of twisting of the connecting belt after it is tightened.

[0071] In some examples, reference Figure 5 , Figure 6 and Figure 7 In this embodiment, a plurality of fixing belts 53 are provided on the connecting belt 5 , and the plurality of fixing belts 53 are distributed along the length direction of the connecting belt 5 . The fixing belts 53 are used to fix the telescopic rod 1 and connect the telescopic rod 1 to the connecting belt 5 .

[0072] Exemplarily, the fixing belt 53 is an elastic belt, and in normal state, the belt surface of the fixing belt 53 is in contact with the belt surface of the connecting belt 5. When the telescopic rod 1 needs to be connected to the connecting belt 5, the telescopic rod 1 is passed through all the fixing belts 53 in sequence, and the fixing belts 53 fix the telescopic rod 1 on the belt surface of the connecting belt 5 under the elastic action.

[0073] In other embodiments, the fixing belt 53 may be two binding belts, and the two fixing belts 53 are respectively located at the two ends of the connecting belt 5 , and the fixing belts 53 fix the telescopic rod 1 to the connecting belt 5 by binding.

[0074] By adopting the above technical solution, the fixing belt is used to fix the telescopic rod to the connecting belt. When the maintenance personnel need to hold the telescopic rod by hand to pass through the connecting hardware, the telescopic rod can be fixed to the connecting belt in advance. The telescopic rod protects the maintenance personnel and is easy to grasp, making the process of maintenance personnel passing through the connecting hardware safer and reducing safety hazards during the maintenance process.

[0075] In some examples, reference Figure 5 and Figure 6 The other end of the connecting belt 5 is connected to a connecting hook 51, and the connecting hook 51 is used to hook the electric tower 6.

[0076] In some embodiments, reference Figure 5 The connecting belt 5 is a tightening belt, and a tightener 54 is provided on the connecting belt 5. The maintenance personnel can adjust the tightness of the connecting belt 5 through the tightener 54.

[0077] After the hook body 3 is hooked on the triangular connecting plate 63, the connecting hook 51 is hung on the electric tower 6. At this time, the connecting belt 5 is tightened, the clamping member 4 is subjected to force, and the triangular connecting plate 63 is clamped between the clamping member 4 and the second hook section 33. The tighter the connecting belt 5 is stretched, the tighter the triangular connecting plate 63 is clamped, thereby reducing the possibility of the hook body 3 moving on the triangular connecting plate 63.

[0078] The embodiment of the present application also discloses a live working operation method, which uses the live working device as described above, and includes the following steps:

[0079] S1: Climbing the tower: Bring the auxiliary insulating rod and the hook to the tower 6;

[0080] Before the above steps, adjust the telescopic rod 1 to the retracted state to avoid bumping when climbing the tower.

[0081] S2: Hooking: Connect the connecting ring 2 with the hook body 3, extend the telescopic rod 1, and send the hook body 3 to the triangular connecting plate 63 for hooking through the auxiliary insulating rod.

[0082] Before performing step S2 , it is selected whether to connect the auxiliary insulating rod to the connecting belt 5 .

[0083] S21: If you choose to connect the auxiliary insulating rod to the connecting belt 5, first pass the telescopic rod 1 through several fixing belts 53 close to the hook body 3, then open the connecting ring 2, hang the second movable ring 3111 on the connecting ring 2, and then extend the telescopic rod 1 step by step. When extending, pass the telescopic rod 1 through the fixing belt 53 in time, hold the telescopic rod 1 and send the hook body 3 to the triangular connecting plate 63, and then hang the hook body 3 on the triangular connecting plate 63; when the hook body 3 is hung, gently pull the telescopic rod 1 to open the connecting ring 2 due to the abutment force, and then slightly adjust the connecting ring 2 to take it out of the second movable ring 3111, and finally retract the auxiliary insulating rod.

[0084] The reason for taking the connecting ring 2 out of the second movable ring 3111 is to facilitate tightening the connecting belt 5 in the subsequent steps.

[0085] In other embodiments, if the fixing belt 53 fixes the telescopic rod 1 by buckling or binding, it is possible to choose whether to connect the telescopic rod 1 to the connecting belt 5 before extending the telescopic rod 1 or before hanging the hook body 3 on the triangular connecting plate 63.

[0086] S22: If you choose not to connect the auxiliary insulating rod to the connecting belt 5, directly buckle the connecting ring 2 with the second movable ring 3111, then extend the telescopic rod 1 step by step, send the hook body 3 to the triangular connecting plate 63 through the telescopic rod 1, then hang the hook body 3 on the triangular connecting plate 63, gently pull the telescopic rod 1 to make the connecting ring 2 open due to the abutment force, then make a slight adjustment to take the connecting ring 2 out of the second movable ring 3111, and finally retract the auxiliary insulating rod.

[0087] By adopting the above technical solution, during the actual construction, when walking while holding the connecting belt, it may be difficult to support because the connecting belt is soft. Holding the connecting belt with both hands will cause an unstable grip between the two hands. At the same time, the connecting belt is a flexible belt. When a person accidentally deviates, the connecting belt will bend and deform after applying force on the connecting belt, which has a poor protective effect on the human body. Therefore, maintenance personnel can decide whether to connect the auxiliary insulating rod to the connecting belt according to needs. Maintenance personnel can hold the auxiliary insulating rod by hand through the connecting hardware. At the same time, because the rod is a rigid material, it will not easily deform, so it can play a better protective role for the human body. This solution can be selected by people. Maintenance personnel can choose whether to connect the connecting belt with the auxiliary insulating rod according to specific needs, so that maintenance personnel can respond flexibly.

[0088] S3: Through the connecting fitting 62: connect the connecting belt 5 to the tower 6, tighten the connecting belt 5, and hold the connecting belt 5 through the connecting fitting 62 to reach the triangular connecting plate 63.

[0089] Specifically, connect the connecting hook 51 on the connecting belt 5 to the tower 6, tighten the connecting belt 5, adjust the tightness of the connecting belt 5, and make the connecting belt 5 in a taut state; when the auxiliary insulating rod is connected to the connecting belt 5, hold the telescopic rod 1 and the connecting belt 5 to smoothly pass through the connecting hardware 62; when the auxiliary insulating rod is not connected to the connecting belt 5, hold the connecting belt 5 to pass through the connecting hardware 62.

[0090] S4: Lowering the tower: After the operation is completed, the hook body 3 is retracted, the telescopic rod 1 is retracted, and the auxiliary insulating rod and the hook are brought down the tower 6 together.

[0091] Specifically, loosen the connecting belt 5, adjust the connection between the hook body 3 and the triangular connecting plate 63 to a loose state, adjust the angle and pull several times to retract the hook body 3. If the hook body 3 is not easy to be pulled back from the triangular connecting plate 63, use the auxiliary insulating rod to poke several times, separate the hook body 3 from the triangular connecting plate 63 with the cooperation and assistance of the auxiliary insulating rod, and retract the hook body 3 through the connecting belt 5.

[0092] Afterwards, the telescopic rod 1 is adjusted to the retracted state, and the auxiliary insulating rod and the hook are lowered from the tower together, thus completing a maintenance operation.

[0093] By adopting the above technical scheme, when it is necessary to inspect and repair the insulator string of the high-altitude electric tower, first, the auxiliary insulating rod and the hook in the retracted state are brought to the tower, and the auxiliary insulating rod is in a tightened state, so that the auxiliary insulating rod is easy to carry, and the hook body is hung on the triangular connecting plate through the extended auxiliary insulating rod, and then the other end of the connecting belt is fixed on the electric tower and tightened, so that the maintenance personnel can hold the connecting belt through the connecting hardware; the hook body is connected to the auxiliary insulating rod, and the auxiliary insulating rod is held by hand to send the hook body to the triangular connecting plate, and the maintenance personnel do not need to throw the hook body multiple times for hooking, which is convenient for the hook to be accurately hooked on the triangular connecting plate; after the operation is completed, the hook is retracted and the auxiliary insulating rod is retracted at the same time, which is convenient for the maintenance personnel to carry the auxiliary insulating rod down the tower.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in the field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
