Description

Technical Field

[0001] The present invention relates to the technical field of overhead line emergency repair, and in particular to an overhead line emergency repair auxiliary device and a use method thereof. Background Art

[0002] With socioeconomic development, the stability of power supply has become crucial. Overhead transmission lines, the backbone of power transmission, are widely distributed and long-distance. They are susceptible to factors such as severe weather (such as lightning strikes, windstorms, and icing), external damage (such as construction damage and vehicle collisions), natural aging, and municipal relocations, leading to failures or the need for temporary interruptions for power supply. Prompt repair and restoration of power after failures or relocations are paramount in power grid operations and maintenance.

[0003] During emergency repairs or relocations involving power outages on overhead lines, a transfer terminal is required. This terminal needs to be lifted and reliably positioned close to the energized overhead line. Through jumper connections, the power load of the faulty or relocated section of the line that needs to be isolated is temporarily transferred to another healthy line or temporary cable loop, thereby achieving load transfer and minimizing the duration and scope of power outages for users. In related technologies, aerial work platforms are typically used to hoist the transfer terminal. However, during the process of lifting the transfer terminal, the cable connected to the transfer terminal is prone to shaking. Furthermore, the traction for the cable's upward movement is entirely provided by the transfer terminal, which can easily cause the connection between the transfer terminal and the cable to break.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0021] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0022] like Figure 2 、 Figure 3 As shown, an overhead line emergency repair auxiliary equipment provided by an embodiment of the present invention includes a lifting device 100 and a terminal placement platform 200 arranged on the lifting device 100. The lifting device 100 is used to drive the terminal placement platform 200 to rise and fall, and the terminal placement platform 200 is used to place the power transfer terminal 10.

[0023] Please refer to Figures 1 to 4 It is understood that the transfer terminal 10 can be placed on the terminal placement platform 200 and then raised and lowered by the lifting device 100. Specifically, the transfer terminal 10 can be first placed on the terminal placement platform 200, and then the lifting device 100 can be used to lift the transfer terminal 10 close to the overhead line 40. After the transfer terminal 10 is close to the overhead line 40, the wires of the overhead line 40 can be connected to the transfer terminal 10 using a jumper 50. It should be noted that the transfer terminal 10 is connected to the cable 20, and the cable 20 is connected to the transfer equipment, which is used to connect to the power-consuming equipment. In this way, with the help of the transfer terminal 10, cable 20, and transfer equipment, electricity can be transmitted to the power-consuming equipment across the fault section or relocation section of the overhead line 40.

[0024] like Figure 2As shown, it should be noted that the overhead line emergency repair auxiliary equipment further includes a mounting seat 400 , and the lifting device 100 is arranged on the mounting seat 400 , and the mounting seat 400 is used to provide support for the lifting device 100 .

[0025] The mounting base 400 may be equipped with driving wheels, so that the mounting base 400 can move on the ground.

[0026] Furthermore, a support leg 500 is provided on the mounting base 400, and the support leg 500 can be extended downward or retracted upward. When the support leg 500 is in the retracted state, it will not affect the movement of the mounting base 400. After the support leg 500 is extended downward, it can be supported on the ground to improve the stability of the equipment.

[0027] Combine Figure 3 and Figure 4 In some embodiments, the overhead line emergency repair auxiliary equipment further includes a cable guide rail 300, which is arranged on the mounting seat 400, with the top end of the cable guide rail 300 facing upward and the bottom end of the cable guide rail 300 facing away from the mounting seat 400.

[0028] It can be understood that after the transfer terminal 10 is placed on the terminal placement platform 200, the cable 20 connected to the transfer terminal 10 can be passed through the cable guide rail 300; in this way, when the subsequent lifting device 100 drives the transfer terminal 10 to lift and lower, the cable 20 can move along the cable guide rail 300, thereby improving the stability of the cable 20 during the lifting process and improving the problem of large shaking of the cable 20.

[0029] Combine Figure 3 、 Figure 5 and Figure 6 Specifically, the cable guide rail 300 includes two mounting plates 310 arranged in parallel and at intervals, and a wire passing channel is formed between the two mounting plates 310. The top of the wire passing channel is set upward, and the bottom end of the wire passing channel is set back to the mounting seat 400; the cable guide rail 300 also includes a plurality of guide roller assemblies 320 arranged at intervals along the extension direction of the wire passing channel.

[0030] It can be understood that the cable 20 is passed between the two mounting plates 310 and is guided by the guide roller assembly 320 .

[0031] Furthermore, the guide roller assembly 320 includes two guide rollers 321, both ends of the two guide rollers 321 are respectively connected to the two mounting plates 310, and the two guide rollers 321 are arranged at intervals, wherein the spacing direction of the two guide rollers 321 is perpendicular to the spacing direction of the two mounting plates 310, and a line gap is formed between the two guide rollers 321.

[0032] It can be understood that the cable 20 is inserted between the two mounting plates 310 and into the wire gap of each guide roller assembly 320. The cable 20 is guided by the two guide rollers 321 of the guide roller assembly 320, and the guide rollers 321 and the cable 20 are in rolling cooperation.

[0033] like Figure 6 As shown, further, one of the guide rollers 321 in the guide roller assembly 320 is used to provide support for the cable 20, and the other guide roller 321 is detachably connected to the two mounting plates 310, wherein the other guide roller 321 and the two mounting plates 310 can be detachably connected via a pin.

[0034] It will be appreciated that one of the guide rollers 321 (the lower guide roller 321) in the guide roller assembly 320 is used to support the cable 20 and bear the weight of the cable 20, while the other guide roller 321 (the upper guide roller 321) cooperates with it to prevent the cable 20 from moving. Before placing the cable 20 on the cable guide 300, the non-supporting guide roller 321 is removed. At this point, the cable 20 can be placed on the supporting guide roller 321 first, and then the non-supporting guide roller 321 can be installed to prevent the cable 20 from moving.

[0035] like Figure 9 As shown, the power transfer terminal 10 includes a base plate 11 and a terminal body 12 disposed on the base plate 11, wherein the terminal body 12 is used to connect the cable 20, and the base plate 11 is provided with a first assembly hole 13. Specifically, the first assembly hole 13 passes through the upper and lower sides of the base plate 11.

[0036] Combine Figure 7 and Figure 8 The terminal placement platform 200 includes a base 210 and a support plate 220 . The support plate 220 is disposed on the base 210 and is used to support the power transfer terminal 10 .

[0037] The support plate 220 is provided with an avoidance notch 221, and the support plate 220 is provided with a second assembly hole 222; wherein, the projection of the avoidance notch 221 on the horizontal plane is located to the side of the projection of the base 210 on the horizontal plane, and the two (the projection of the avoidance notch 221 on the horizontal plane and the projection of the base 210 on the horizontal plane) do not overlap.

[0038] Please refer to Figures 8 to 11It can be understood that the specific process of placing the power conversion terminal 10 on the terminal placing platform 200 is that the power conversion terminal 10 is moved from the side of the support plate 220 to the avoiding gap 221, so that the cable 20 connected with the terminal main body 12 is inserted into the avoiding gap 221, and the bottom plate 11 is stacked on the support plate 220, and the first assembly hole 13 and the second assembly hole 222 are arranged opposite to each other, then the fastener 30 is inserted into the first assembly hole 13 and the second assembly hole 222, so as to fix the support plate 220 and the bottom plate 11. The first assembly hole 13 and the second assembly hole 222 can be through holes, and the fastener 30 is a bolt and nut set. The bolt is inserted into the first assembly hole 13 and the second assembly hole 222, and the bolt is locked by the nut, so as to fix the support plate 220 and the bottom plate 11.

[0039] As shown in Figure 7 , further, the terminal placing platform 200 includes three support plates 220, and the three support plates 220 are arranged on the base 210 and are used to support the three power conversion terminals 10 respectively.

[0040] By means of the terminal placing platform 200, the three power conversion terminals 10 can be placed, and the operation of placing the power conversion terminal 10 on the support plate 220 is simple. Specifically, in the process of placing the power conversion terminal 10, the cable 20 will not interfere with the terminal placing platform 200 (the avoiding gap 221 is arranged, the support plate 220 will not interfere with the cable 20, and the projection of the avoiding gap 221 on the horizontal plane does not coincide with the projection of the base 210 on the horizontal plane, and the base 210 will not interfere with the cable 20), in addition, by stacking the bottom plate 11 of the power conversion terminal 10 on the support plate 220 and aligning the first assembly hole 13 and the second assembly hole 222, the bottom plate 11 and the support plate 220 are fixed by means of the fastener 30, so as to fix the power conversion terminal 10, and the operation is simple.

[0041] In combination with Figure 7 and Figure 8 , the support plate 220 has a connecting portion 223 and an avoiding portion 224. The connecting portion 223 is connected to the base 210, and the avoiding portion 224 extends to the side of the base 210. The projection of the avoiding portion 224 on the horizontal plane is located to the side of the projection of the base 210 on the horizontal plane, and the two projections do not coincide with each other. The avoiding gap 221 is arranged in the avoiding portion 224.

[0042] It is understood that the connecting portion 223 is disposed on the base 210 and is fixed to the base 210 by bolts, while the relief portion 224 extends from the side of the base 210 so that the projection of the relief portion 224 on the horizontal plane is located to the side of the projection of the base 210 on the horizontal plane, and the two do not overlap. The relief notch 221 is formed in the relief portion 224 and penetrates the side of the relief portion 224 away from the connecting portion 223. It should be noted that the relief notch 221 also penetrates the upper and lower sides of the relief portion 224.

[0043] It should be noted that the three support plates 220 are spaced apart on a horizontal plane, and their projections on the horizontal plane do not overlap. It is understood that the three support plates 220 are disposed at the edges of the base 210 and spaced apart along the circumference of the base 210. This allows the three transfer terminals 10 to be installed independently of each other when they are placed on the three support plates 220.

[0044] like Figure 7 As shown, three support plates 220 are defined as a first support plate 220a, a second support plate 220b, and a third support plate 220c. The avoidance portion 224 of the first support plate 220a is oriented in a first direction, the avoidance portion 224 of the second support plate 220b is oriented in a second direction, and the avoidance portion 224 of the third support plate 220c is oriented in a third direction. The angle between the first direction and the second direction is an acute angle, and the angle between the first direction and the third direction is also an acute angle. In other words, the avoidance portion 224 of each support plate 220 is oriented toward the same side ( Figure 7 In this way, the three power transfer terminals 10 can be placed on the three support plates 220 from left to right.

[0045] Specifically, the first direction is facing left, the second direction is facing left and deviates from the first direction by a certain angle (preferably within 45°), and the second direction is facing left and also deviates from the first direction by a certain angle (preferably within 45°).

[0046] Combine Figure 3 and Figure 7 As will be appreciated, the three cables 20 connecting the power transfer equipment extend in essentially the same direction. For ease of understanding, the power transfer equipment is located to the left of the overhead line emergency repair auxiliary equipment. The left end of each cable 20 is connected to the power transfer equipment, while the right end of each cable 20 is connected to a power transfer terminal 10. By orienting the relief portion 224 of each support plate 220 substantially to the left, the three power transfer terminals 10 can be positioned on the three support plates 220 from left to right, making operation more convenient.

[0047] like Figure 7As shown, further, a plane perpendicular to the first direction is defined as a reference plane, and the projection of the first support plate 220a on the reference plane is located between the projection of the second support plate 220b on the reference plane and the projection of the third support plate 220c on the reference plane.

[0048] like Figure 7 As shown, in some embodiments, the terminal placement platform 200 further includes a fence 230 disposed on the base 210. It is understood that when the transfer terminal 10 is placed on the terminal placement platform 200, the terminal placement platform 200 is at a certain distance from the ground (typically 2m-4m). Placing the transfer terminal 10 on the support plate 220 requires an operator to climb onto the base 210 for operation. The provision of the fence 230 ensures the operator's safety.

[0049] Furthermore, the fence 230 is detachably connected to the base 210 .

[0050] It is understood that before the three transfer terminals 10 are placed on the terminal placement platform 200, the fence 230 is connected to the base 210. This provides safety for the operator during the placement of the transfer terminals 10 on the support plate 220. After the three transfer terminals 10 are placed, the fence 230 can be removed. It should be noted that before the fence 230 is removed, the distance between the fence 230 and the three transfer terminals 10 is relatively close, and electricity near the transfer terminals 10 can easily hit the fence 230, posing a safety hazard. Removing the fence 230 can reduce these safety hazards.

[0051] Specifically, the fence 230 includes three guardrails 231, which are arranged at the edge of the base 210 and spaced apart along the circumference of the base 210. An avoidance space 240 is formed between each adjacent two guardrails 231, and the avoidance space 240 is used to avoid the power transfer terminal 10 placed on the support plate 220.

[0052] Combine Figure 4 and Figure 5 The number of the cable guide rails 300 is three, and the three cable guide rails 300 correspond to the three support plates 220. Top ends of the three cable guide rails 300 are respectively disposed toward the avoidance gaps 221 of the three support plates 220 .

[0053] It is understandable that after the three transfer terminals 10 are respectively placed on the three support plates 220 of the terminal placement platform 200, the three cables 20 connected to the three transfer terminals 10 can be respectively passed through the three cable guides 300; in this way, when the subsequent lifting device 100 drives the three transfer terminals 10 to be lifted or lowered, the three cables 20 can be respectively moved along the three cable guides 300. On the one hand, the stability of the cables 20 during the lifting process can be improved, and the problem of large shaking of the cables 20 can be improved. In addition, in the corresponding cable guides 300 and support plates 220, the top of the cable 20 terminal is set towards the avoidance notch 221 of the support plate 220. The cable 20 located between the cable guides 300 and the support plate 220 has a better verticality, which can improve the oblique pulling problem caused by the cable 20 exerting an oblique force on the transfer terminal 10, thereby improving the safety of the transfer terminal 10.

[0054] like Figure 12 As shown, in some embodiments, the lifting device 100 is a mast-type lifting device, which can drive the terminal placement platform 200 to rise and fall.

[0055] Specifically, the lifting device 100 includes a mast assembly 110. The mast assembly 110 can be extended upward to drive the terminal placement platform 200 to rise, and the mast assembly 110 can also be retracted downward to drive the terminal placement platform 200 to descend.

[0056] Combine Figure 12 and Figure 13 Specifically, in this embodiment, the lifting device 100 includes two mast assemblies 110, which are spaced apart horizontally. The terminal placement platform 200 is supported by both mast assemblies 110. Both mast assemblies 110 can simultaneously extend upward or retract downward, driving the terminal placement platform 200 upward or downward. The simultaneous support of the terminal placement platform 200 by the two mast assemblies 110 provides greater stability and improves operator safety.

[0057] Combine Figure 12 and Figure 13 The mast assembly 110 includes a fixed mast 111 , a first lifting mast 112 liftably disposed on the fixed mast 111 , and a second lifting mast 113 liftably disposed on the first lifting mast 112 .

[0058] Specifically, the fixed mast 111 is fixedly mounted on the mounting base 400; the first lifting mast 112 is mounted on the fixed mast 111 and can be raised and lowered relative to the fixed mast 111; the second lifting mast 113 is mounted on the first lifting mast 112 and can be raised and lowered relative to the first lifting mast 112; the terminal placement platform 200 is mounted on the second lifting mast 113.

[0059] It should be noted that one or more lifting masts can be set between the first lifting mast 112 and the fixed mast 111, one or more lifting masts can be set between the second lifting mast 113 and the first lifting mast 112, and one or more lifting masts can be set between the terminal placement platform 200 and the second lifting mast 113.

[0060] The first clamping device 600 is mounted on the first lifting mast 112 and is used to clamp the cable 20 connected to the transfer terminal 10. The second clamping device 700 is mounted on the second lifting mast 113 and is also used to clamp the cable 20. It should be noted that the number of first clamping devices 600 and second clamping devices 700 corresponds to the number of support plates 220. Specifically, in this embodiment, there are three support plates 220, and three first clamping devices 600 and three second clamping devices 700. In the corresponding support plates 220, first clamping devices 600, and second clamping devices 700, the support plate 220 is used to support the transfer terminal 10, and the first clamping device 600 and second clamping device 700 are used to clamp the cable connected to the transfer terminal 10. In other embodiments, there is only one support plate 220, and there is also only one first clamping device 600 and second clamping device 700.

[0061] It should be noted that the first clamping device 600 and the second clamping device 700 may be electric clamping devices that can be controlled to automatically clamp or release the cable 20 .

[0062] When the lifting device 100 drives the terminal placement platform 200 on which the transfer terminal 10 is placed to rise, the second lifting mast 113 rises before the first lifting mast 112. Specifically, when the mast assembly 110 drives the terminal placement platform 200 to rise, not all lifting masts rise together, but each lifting mast rises in sequence, among which the second lifting mast 113 rises (extends upward) before the first lifting mast 112.

[0063] Furthermore, in the process of the lifting device 100 driving the terminal placement platform 200 on which the transfer terminal 10 is placed to rise, the second clamping device 700 clamps the cable 20 before the first clamping device 600, and when the relative position of the cable 20 relative to the second clamping device 700 in the vertical direction is fixed (when the relative position relationship of the cable 20 relative to the second clamping device 700 in the vertical direction is no longer affected by the extension of the mast assembly 110), the second clamping device 700 performs the clamping action on the cable 20, and when the relative position of the cable 20 relative to the first clamping device 600 in the vertical direction is fixed (when the relative position relationship of the cable 20 relative to the first clamping device 600 in the vertical direction is no longer affected by the extension of the mast assembly 110), the first clamping device 600 performs the clamping action on the cable 20.

[0064] It is understandable that, since not all lifting masts rise together when the mast assembly 110 drives the terminal placement platform 200 to rise, but each lifting mast rises in sequence, therefore, within a certain period of time, the cable 20 will not move relative to the second lifting mast 113 in the vertical direction, but will move relative to the first lifting mast 112 in the vertical direction. If the first clamping device 600 and the second clamping device 700 clamp the cable 20 at the same time in the initial stage of the mast assembly 110 driving the terminal placement platform 200 to rise, then, when the mast assembly 110 is subsequently extended, the cable 20 will be pulled by the first clamping device 600 and the second clamping device 700 and there is a risk of breakage. In the present application, since the second lifting mast 113 rises before the first lifting mast 112 during the process of the lifting device 100 driving the terminal placement platform 200 on which the power transfer terminal 10 is placed, the second lifting mast 113 rises before the first lifting mast 112. Therefore, when the cable 20 rises, the second lifting mast 113 will maintain a relatively static state with the cable 20 in the vertical direction before the first lifting mast 112. Therefore, by making the second clamping device 700 clamp the cable 20 before the first clamping device 600, and the second clamping device 700 performs the clamping action on the cable 20 when the relative position relationship of the cable 20 relative to the second clamping device 700 in the vertical direction is no longer affected by the extension of the mast assembly 110, and the first clamping device 600 performs the clamping action on the cable 20 when the relative position relationship of the cable 20 relative to the first clamping device 600 in the vertical direction is no longer affected by the extension of the mast assembly 110, it is possible to prevent multiple clamping devices from clamping the cable 20 at the same time, causing the cable 20 to be pulled and broken.

[0065] It should be emphasized that, in the present application, the cable 20 is clamped by means of a first clamping device 600 and a second clamping device 700 (using multiple clamping devices), which can further improve the problem of the shaking of the cable 20 compared to the solution of clamping the cable 20 without the help of a clamping device or only with the help of a single clamping device. Moreover, after the second clamping device 700 first clamps the cable 20, the second clamping device 700 can provide an upward traction force for the cable 20, thereby improving the problem that the traction force of the cable 20 is entirely provided by the transfer terminal 10, resulting in the connection position between the cable 20 and the transfer terminal 10 being easily broken. Moreover, when the first clamping device 600 clamps the cable 20 again, the first clamping device 600 can also provide an upward traction force for the cable 20, thereby further reducing the burden on the second clamping device 700 and the transfer terminal 10. Furthermore, it is precisely because the lifting masts in the mast assembly 110 ascend sequentially, rather than synchronously, that it is possible to utilize the first clamping device 600 and the second clamping device 700 (or multiple clamping devices) to clamp the cable 20. This is because, if the lifting masts ascend synchronously, during the upward deployment of the mast assembly 110, except for the top mast 114 (the lifting mast that can ascend to the highest point and is directly connected to the terminal placement platform 200), the remaining lifting masts and the cable 20 maintain a state of relative vertical motion. The remaining lifting masts are no longer equipped with corresponding clamping devices to clamp the cable 20 and provide traction for the cable 20 to ascend.

[0066] In addition, when the lifting device 100 drives the terminal placement platform 200 with the power transfer terminal 10 to descend, the first lifting mast 112 descends before the second lifting mast 113, and the first clamping device 600 releases the cable 20 before the second clamping device 700.

[0067] It can be understood that, in the process of the lifting device 100 driving the terminal placement platform 200 on which the transfer terminal 10 is placed to descend, the first lifting mast 112 descends before the second lifting mast 113. When the first lifting mast 112 is in a fully retracted state, the first clamping device 600 can first release the cable 20 to avoid the problem that the first clamping device 600 cannot clamp the cable 20 and cause the cable 20 to slide down smoothly. At this time, the second clamping device 700 still clamps the cable 20 to provide traction for the cable 20, improving the problem that the traction force of the cable 20 is entirely provided by the transfer terminal 10, which causes the connection position between the cable 20 and the transfer terminal 10 to be easily broken. When the second lifting mast 113 is in a fully retracted state, the second clamping device 700 can release the cable 20 again.

[0068] like Figures 13 to 15As shown, in some embodiments, the fixed mast 111, the first lifting mast 112 and the second lifting mast 113 are arranged along a horizontal direction, and the mast assembly 110 further comprises a pulling rope 116 and a pulling rope winding and unwinding device 115, one end of the pulling rope 116 is connected to the pulling rope winding and unwinding device 115, and the pulling rope 116 is connected to the fixed mast 111, the first lifting mast 112 and the second lifting mast 113.

[0069] When the pulling rope winding and unwinding device 115 winds up the pulling rope 116, the pulling rope 116 pulls the second lifting mast 113 to rise to a fully extended state, and then pulls the first lifting mast 112 to rise to a fully extended state. It should be noted that when the second lifting mast 113 is fully unfolded upward, the second lifting mast 113 can be locked by a locking device to avoid falling, and when the first lifting mast 112 is fully unfolded upward, the first lifting mast 112 can be locked by another locking device to avoid falling. When the pulling rope winding and unwinding device 115 unwinds the pulling rope 116, the locking device for locking the first lifting mast 112 is unlocked first, and then the locking device for locking the second lifting mast 113 is unlocked, and the second lifting mast 113 is lowered to a fully retracted state due to gravity.

[0070] It should be noted that the locking device can be any locking device in the prior art. For example, for the locking device for locking the second lifting mast 113, an extendable electric push rod can be arranged at the bottom of the second lifting mast 113, and a corresponding lock hole can be arranged at the top of the lifting mast adjacent to and behind the second lifting mast 113. When the second lifting mast 113 is fully unfolded upward, the electric push rod can be inserted into the lock hole to lock the second lifting mast 113. It can be understood that the locking devices on other lifting masts can also be arranged in the same way as the locking device for locking the second lifting mast 113, and will not be described here.

[0071] The pulling rope winding and unwinding device 115 can be a winding and unwinding wheel device that can rotate forward or reverse. When the winding and unwinding wheel device rotates forward, the pulling rope 116 can be wound up. When the winding and unwinding wheel device rotates reversely, the lifting mast is lowered due to gravity and pulls out the pulling rope 116 on the winding and unwinding wheel device.

[0072] Specifically, the mast assembly 110 also includes a top mast section 114, the fixed mast 111 is provided with two first pulleys 1111 arranged at intervals along the height direction, the first lifting mast 112 is provided with two second pulleys 1121 arranged at intervals along the height direction, and the second lifting mast 113 is provided with two third pulleys 1131 arranged at intervals along the height direction. The pull rope 116 passes from the pull rope retracting and releasing component 115 around the first pulley 1111 at the bottom, the first pulley 1111 at the top, the second pulley 1121 at the bottom, the second pulley 1121 at the top, the third pulley 1131 at the bottom, and the third pulley 1131 at the top, and the end of the pull rope 116 away from the pull rope retracting and releasing component 115 is connected to the bottom of the top mast section 114. In this way, when the rope retracting and releasing component 115 reels the rope 116, the rope 116 will first pull the top mast section 114 up to a fully extended state, and then pull the second lifting mast 113 up to a fully extended state, and then pull the first lifting mast 112 up to a fully extended state. It should be noted that when the top mast section 114 is fully extended upward, the top mast section 114 can be locked by a locking device to prevent it from falling. When the second lifting mast 113 is fully extended upward, the second lifting mast 113 can be locked by a locking device to prevent it from falling. When the first lifting mast 112 is fully extended upward, the first lifting mast 112 can be locked by another locking device to prevent it from falling. When the pull rope retracting member 115 extends the pull rope 116, the locking device for locking the first lifting mast 112 is first unlocked, and the first lifting mast 112 first descends to a fully retracted state. Thereafter, the locking device for locking the second lifting mast 113 is unlocked again, and the second lifting mast 113 descends to a fully retracted state. Thereafter, the locking device for locking the top section mast 114 is unlocked again, and the top section mast 114 descends to a fully retracted state.

[0073] In other embodiments, the second lifting mast 113 is a top section mast, the fixed mast 111 is provided with two first pulleys 1111 spaced apart along the height direction, the first lifting mast 112 is provided with two second pulleys 1121 spaced apart along the height direction, the pull rope 116 passes from the pull rope retracting component 115 around the first pulley 1111 located below, the first pulley 1111 located above, the second pulley 1121 located below, and the second pulley 1121 located above in sequence, and the end of the pull rope 116 away from the pull rope retracting component 115 is connected to the bottom of the second lifting mast 113. In this way, when the pull rope retracting member 115 reels the pull rope 116, the pull rope 116 will first pull the second lifting mast 113 up to a fully extended state, and then pull the first lifting mast 112 up to a fully extended state. It should be noted that when the second lifting mast 113 is fully extended upward, the second lifting mast 113 can be locked by a locking device to prevent it from falling. When the first lifting mast 112 is fully extended upward, the first lifting mast 112 can be locked by another locking device to prevent it from falling. When the pull rope retracting member 115 releases the pull rope 116, the locking device used to lock the first lifting mast 112 is first unlocked. After the first lifting mast 112 descends to a fully retracted state due to gravity, the locking device used to lock the second lifting mast 113 is unlocked again, and the second lifting mast 113 descends to a fully retracted state due to gravity again.

[0074] Combine Figure 16 and Figure 17 In some embodiments, the first clamping device 600 and the second clamping device 700 have the same structure, including a housing 610, a movable clamping block 630 disposed on the housing 610, a linear drive 640 drivingly connected to the movable clamping block 630, and a fixed clamping block 620 disposed on the housing 610. The movable clamping block 630 and the fixed clamping block 620 are disposed opposite each other, and the linear drive 640 is used to drive the movable clamping block 630 toward or away from the fixed clamping block 620. The linear drive 640 may be an electric push rod.

[0075] It can be understood that when the linear drive member 640 drives the movable clamp 630 to approach the fixed clamp 620, the cable 20 located between the movable clamp 630 and the fixed clamp 620 can be clamped, and when the linear drive member 640 drives the movable clamp 630 away from the fixed clamp 620, the cable 20 located between the movable clamp 630 and the fixed clamp 620 can be loosened.

[0076] It should be noted that the first clamping device 600 has a first clamping area (the area between the movable clamping block 630 and the fixed clamping block 620 of the first clamping device 600), through which the cable 20 passes. The second clamping device 700 has a second clamping area (the area between the movable clamping block and the fixed clamping block of the second clamping device 700), through which the cable 20 passes. In the corresponding support plate 220, the first clamping device 600, and the second clamping device 700, the avoidance notch 221, the first clamping area, and the second clamping area are arranged in a vertically opposed relationship. This allows the cable 20 between the cable guide 300 and the support plate 220 to extend vertically.

[0077] Furthermore, the fixed clamp 620 is detachably connected to the shell 610. After the transfer terminal 10 is installed on the terminal placement platform 200, the fixed clamp 620 can be removed first so that the cable 20 fits the movable clamp 630, and then the fixed clamp 620 can be installed on the shell 610 so that the cable 20 is placed between the fixed clamp 620 and the movable clamp 630.

[0078] The fixing clamp 620 can be detachably connected to the housing 610 by using a pin, a screw or a buckle.

[0079] It should be noted that the mast assembly 110, the first clamping device 600, and the second clamping device 700 can be connected to a controller to control the operations of the mast assembly 110, the first clamping device 600, and the second clamping device 700. Specifically, the rope retracting and releasing member 115, and the linear drive members 640 of the first clamping device 600 and the second clamping device 700 are all electrically connected to the controller.

[0080] An embodiment of the present invention further provides a method for using an overhead line emergency repair auxiliary device, which comprises the following steps: S100 , placing the power transfer terminal 10 on the terminal placement platform 200 .

[0081] It can be understood that when diversion and power transfer are required due to municipal relocation or overhead line failure, the overhead line emergency repair auxiliary equipment is transported to a suitable location where diversion and power transfer are required and placed stably, and then the support legs 500 are extended downward and rested on the ground so that the equipment is stable and reliable when in use; then, each power transfer terminal 10 is placed on the terminal placement platform 200; thereafter, the cable 20 is passed through the first clamping area of ​​the first clamping device 600, the second clamping area of ​​the second clamping device 700 and the wire passage of the cable guide 300; then, the fence 230 is removed.

[0082] S200: Lift the power transfer terminal 10.

[0083] like Figures 13 to 15As shown, specifically, the mast assembly 110 drives the terminal placement platform 200, on which the transfer terminal 10 is placed, to rise. More specifically, each lifting mast deploys upward sequentially, with the second lifting mast 113 rising before the first lifting mast 112. Furthermore, during the lifting process of the transfer terminal 10, the cable 20 connected to the transfer terminal 10 is also lifted by the mast assembly 110. During this process, when the vertical relative position of the cable 20 and the second clamping device 700 is fixed (the fixed vertical relative position of the cable 20 and the second clamping device 700 is no longer affected by the extension of the mast assembly 110), the second clamping device 700 clamps the cable 20. Furthermore, when the vertical relative position of the cable 20 and the first clamping device 600 is fixed (the vertical relative position of the cable 20 and the first clamping device 600 is no longer affected by the extension of the mast assembly 110), the first clamping device 600 clamps the cable 20.

[0084] It is understandable that during the lifting of the power transfer terminal 10, when the top mast 114 is fully extended upward, no matter which lifting mast is extended upward thereafter, the relative position of the cable 20 and the second lifting mast 113 in the vertical direction will no longer change, and the relative position of the cable 20 and the second clamping device 700 provided on the second lifting mast 113 in the vertical direction will no longer change. At this time, the second clamping device 700 clamps the cable 20; it is also understandable that during the lifting of the power transfer terminal 10, when the first lifting mast 112 is close to the previous lifting mast of the second lifting mast 113 and is fully extended upward, no matter which lifting mast is extended upward thereafter, the relative position of the cable 20 and the first lifting mast 112 in the vertical direction will no longer change, and the relative position of the cable 20 and the first clamping device 600 provided on the first lifting mast 112 in the vertical direction will no longer change. At this time, the first clamping device 600 clamps the cable 20.

[0085] It should be noted that a first sensor can be set to detect the specific position of the top mast section 114. When the first sensor detects that the top mast section 114 is fully extended upward, the first sensor sends data to the controller, which controls the second clamping device 700 to perform the clamping action on the cable 20; a second sensor can also be set to detect the specific position of the previous lifting mast of the first lifting mast 112 close to the second lifting mast 113. When the second sensor detects that the previous lifting mast of the first lifting mast 112 close to the second lifting mast 113 is fully extended upward, the second sensor sends data to the controller, which controls the first clamping device 600 to perform the clamping action on the cable 20.

[0086] At S300 , the electric wires of the overhead line 40 are connected to the power transfer terminal 10 using the jumper wire 50 .

[0087] Specifically, after the terminal placement platform 200 is lifted to a suitable position, the jumper 50 is used to drain the overhead line 40, transferring the current from the high overhead line 40 to the transfer terminal 10, and then transferred to the ground transfer equipment through the cable 20 connected to the transfer terminal 10, and then the transfer equipment transfers the current across the fault section or relocation section to the power-consuming equipment.

[0088] S400, remove jumper 50.

[0089] Specifically, after the project is completed, the jumper 50 is removed.

[0090] S500: Move the power transfer terminal 10 downward.

[0091] Specifically, the lifting device 100 drives the terminal placement platform 200 downward. More specifically, the lifting masts are sequentially retracted downward, with the first lifting mast 112 descending before the second lifting mast 113. In other words, the order in which the lifting masts are retracted downward when the mast assembly 110 drives the terminal placement platform 200 downward is opposite to the order in which the lifting masts are deployed upward when the mast assembly 110 drives the terminal placement platform 200 upward. During the process of the lifting device 100 driving the terminal placement platform 200 downward, when the first lifting mast 112 is fully retracted, the first clamping device 600 first releases the cable 20. When the second lifting mast 113 is fully retracted, the second clamping device 700 releases the cable 20.

[0092] S600 , removing the terminal of the cable 20 from the terminal placement platform 200 .

[0093] Specifically, the fence 230 can be reinstalled on the base 210 first, the cable 20 can be removed from the first clamping device 600, the second clamping device 700 and the cable guide 300, and each power transfer terminal 10 can be removed at the same time, and then the support leg 500 can be retracted upward.
