[0021] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0022] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0023] Example 1, with reference to Figures 1 to 4 , this embodiment provides a live working main line and drainage line assembly and disassembly auxiliary device, including a carrying assembly 1, including a carrying frame 11; The transmission assembly 2 includes a threaded rod 231 provided on the inner side of the carrying frame 11; the transmission assembly 2 also includes a handle 21 provided at one end of the carrying frame 11, and a transmission rod 211 is provided at one end of the handle 21 close to the carrying frame 11, and a transmission gear 22 is provided on the outer side of the transmission rod 211; driven gears 23 are meshed at both ends of the transmission gear 22, and the driven gear 23 is fixedly connected to the threaded rod 231. Specifically, the threaded rod 231 and the driven gear 23 are provided with upper and lower groups, and the threaded rod 231 provided on the upper side is fixedly connected to the driven gear 23, and the threaded rod 231 provided on the lower side is fixedly connected to the driven gear 23; a group of transmission gears 22 can be respectively meshed with the upper or lower driven gear 23, wherein, through the transmission gear 22 meshing with the upper driven gear 23, the rotation of the transmission gear 22 drives the upper driven gear 23 to rotate, which can drive When the threaded rod 231 above rotates, a motor can be set on the side of the transmission gear 22 to drive the transmission gear 22 to rotate, or a mechanical arm can be used to drive the transmission gear 22 to rotate; the transmission gear 22 is meshed with the driven gear 23 below, so that the rotation of the transmission gear 22 causes the driven gear 23 below to rotate, which can drive the threaded rod 231 below to rotate; one group of transmission gears 22 is meshed with the driven gear 23 above and the driven gear 23 below at the same time. At this time, when the transmission gear 22 meshes with the driven gears 23 at the upper and lower ends, the two groups of driven gears 23 will rotate and drive the threaded rod 231 in the opposite direction to rotate. By setting opposite threads on the two groups of threaded rods 231, the threaded rod 231 can simultaneously drive the fixed assembly 3 of the upper busbar to descend and drive the fixed assembly 3 of the lower drainage line to rise, which can speed up the approach between the two and save time.

[0024] The fixing assembly 3 includes a transverse connecting seat 31 provided on the outside of the threaded rod 231 and a receiving plate 32 provided on one end of the transverse connecting seat 31; The clamping assembly 4 includes a connecting arc plate 41 disposed on the outside of the receiving plate 32 and an arc-shaped clamping plate 411 disposed on the inside of the connecting arc plate 41. Specifically, the arc-shaped structures of the connecting arc plate 41 and the arc-shaped clamping plate 411 cooperate with the arc-shaped protrusion of the drainage wire pressing plate, making it easier to install and tighten the drainage wire.

[0025] Usage process: When the threaded rods 231 at the upper and lower ends rotate, the two groups of threaded rods 231 will drive the horizontal connecting seat 31 to rise or fall on the side of the supporting frame 11. During the sliding process of the upper horizontal connecting seat 31, the horizontal connecting seat 31 will drive the storage plate 32 with the busbar installed inside to rise and fall, and the lower horizontal connecting seat 31 will drive the drainage line storage plate 32 installed inside to rise and fall. When the upper and lower groups of storage plates 32 are rising and falling, the upper and lower groups of storage plates 32 will move towards or away from each other, and the busbars and drainage lines in the two groups of storage plates 32 will also move towards or away from each other, thereby realizing the function of the drainage lines moving away from or close to the busbars.

[0026] Example 2, reference Figures 1 to 5 This is the second embodiment of the present invention. Unlike the previous embodiment, the fixing assembly 3 further includes a sliding thread groove 311 formed on the inner side of the transverse connecting seat 31. The sliding thread groove 311 is threadedly mounted on the outer side of the threaded rod 231. A rotating shaft is provided at one end of the receiving plate 32. A first elastic member 331 is provided on the outer side of the rotating shaft. A limiting plate 33 is provided on the outer side of the first elastic member 331. The end of the limiting plate 33 away from the first elastic member 331 is inclined. Specifically, the elastic force of the first elastic member 331 exerts an inward force on the limiting plate 33, causing the limiting plate 33 to approach the receiving plate 32, thereby closing the opening of the receiving plate 32 and preventing the busbar from falling off before the fixing work is completed.

[0027] The clamping assembly 4 also includes a sliding transverse groove 432 opened on the inner side of the transverse connecting seat 31, a sliding rod 43 is provided on the inner side of the sliding transverse groove 432, a first ring 431 is provided on the outer side of the sliding rod 43, and an oblique groove 433 is opened on the inner side of the supporting frame 11. Specifically, through the oblique grooves 433 opened on both sides of the supporting frame 11, when the transverse connecting seat 31 drives the sliding rod 43 to descend, the oblique track of the oblique grooves 433 causes the sliding rod 43 to move forward while descending.

[0028] A lifting groove 421 is provided at one end of the storage plate 32 close to the carrying frame 11, and a fixing plate 42 is provided on the inner side of the lifting groove 421. The fixing plate 42 slides on the inner side of the horizontal connecting seat 31. Specifically, the lifting groove 421 provided on the storage plate 32 ensures that the fixing plate 42 will not be blocked during the rising process.

[0029] A connecting block 44 is provided at one end of the fixing plate 42 away from the horizontal connecting seat 31, and a rotating shaft 441 is provided on the inner side of the connecting block 44, and a second ring 4411 is sleeved on the outer side of the rotating shaft 441, and an operating rod 45 is provided between the second ring 4411 and the first ring 431. Specifically, the arc-shaped clamping plate 411 and the connecting arc-shaped plate 41 are designed to form an arc-shaped groove protruding upward, which is convenient for hanging on the busbar and drainage line through the arc-shaped groove during installation; the outward arc-shaped portion of the arc-shaped clamping plate 411 is streamlined with the design of the connecting arc-shaped plate 41, and through its arc-shaped design and the circular shape of the busbar and drainage line, it fits better with its exterior during the clamping process, and the clamping area is larger.

[0030] Usage process: When the busbar and drainage line are respectively installed in the upper and lower storage plates 32, the two sets of threaded rods 231 are rotated, and the corresponding horizontal connecting seats 31 are driven by the threaded rods 231 to move vertically, and the sliding rods 43 on both sides of each set of horizontal connecting seats 31 will pass through the corresponding oblique grooves 433 on both sides of the carrying frame 11 to move in the direction of the storage plate 32. When the sliding rods 43 move forward, the sliding rods 43 will drive the first sleeve 431 on the outside to move. At this time, after the first sleeve 431 moves, the first sleeve 431 drives the second sleeve 4411 and the rotating shaft 441 to rise through the operating rod 45, and the rotating shaft 441 drives the connecting block 44 and the fixed plate 42 to rise. When the fixed plate 42 rises, the fixed plate 42 will drive the connecting arc plate 41 and the arc clamping plate 411 to rise. During the rising process of the arc clamping plate 411, the busbar and drainage line will be clamped and fixed.

[0031] Example 3, reference Figures 1 to 5 , which is the third embodiment of the present invention, and is different from the previous embodiment in that it further includes an expansion component 5, which includes a bearing groove 51 opened below the arc-shaped clamping plate 411, an expansion plate 52 is provided inside the bearing groove 51, and mounting grooves 521 are opened at both ends of the expansion plate 52. An operating shaft 521 is provided inside the mounting groove 521, and the operating shaft 521 is connected to the arc-shaped clamping plate 411. A bearing plate 53 is provided below the expansion plate 52. Specifically, when the outer diameter of the busbar or the drain line is larger than the end face of the arc-shaped clamping plate 411 and When the busbar or drain line is squeezed by the arc-shaped clamping plate 411, the arc-shaped clamping plate 411 will cater to the outer diameter of the busbar or drain line and expand to both sides. The two ends of the expansion plate 52 are respectively rotated and set under the two groups of arc-shaped clamping plates 411. When the two groups of arc-shaped clamping plates 411 expand to both sides and separate, the two groups of arc-shaped clamping plates 411 will respectively pull the two ends of the expansion plate 52 and rotate. At this time, the expansion plate 52 changes from an inclined state to a horizontal state, thereby connecting the two groups of arc-shaped clamping plates 411 through the expansion plate 52.

[0032] A driving shaft 54 ​​is provided on the inner side of the carrying plate 53, and a second elastic member 55 is provided on the outer side of the driving shaft 54. Specifically, after the driving shaft 54 ​​rotates, the driving shaft 54 ​​will drive the second elastic member 55 on the outer side to rotate. Connecting columns 551 are provided at both ends of the second elastic member 55. The connecting columns 551 are connected to the inner side of the carrying plate 53. A limiting plate 56 is provided below the driving shaft 54. A ratchet 561 is provided on the outer side of the limiting plate 56. A cam 562 is provided below the limiting plate 56. A pawl 57 is provided on the inner side of the carrying plate 53. Specifically, the expansion plate 52 is fixed by the limiting plate 56. After that, and when the expansion plate 52 rotates again, the second elastic member 55 will drive the connecting columns 551 at both ends of the second elastic member 55 to twist, so that the second elastic member 55 accumulates elastic potential energy. When the busbar and the drainage line fall off, the convex plate 562 is pressed, and the convex plate 562 will drive the limit plate 56 to rise. After the limit plate 56 rises, the limit plate 56 is located below the pawl 57, so that the limit plate 56 is separated from the limit of the pawl 57, and then through the action of the elastic force of the second elastic member 55, the second elastic member 55 will drive the expansion plate 52 to reset, and the expansion plate 52 drives the arc clamping plate 411 to reset.

[0033] Furthermore, when the expansion plate 52 rotates about the axis, the expansion plate 52 will drive the driving shaft 54 ​​below to rotate, and the driving shaft 54 ​​will drive the limiting plate 56 below to rotate. After the limiting plate 56 rotates, the pawl 57 clamps the ratchet 561 on the outside of the limiting plate 56, thereby fixing the separation of the arc-shaped clamping plate 411.

[0034] Usage process: When encountering high temperature weather, the rubber sleeves on the outside of the busbar and the drainage line will expand due to thermal expansion and contraction, causing the outer diameter of the busbar and the drainage line to increase. When the outer diameter of the busbar and the drainage line increases, the busbar and the drainage line will squeeze the arc-shaped clamping plate 411, and the arc-shaped clamping plate 411 will separate from the middle, and then adapt to the width of the busbar and the drainage line.

[0035] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
