DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0022] Combination Figure 1-Figure 10 The present invention discloses an installation device for an aluminum alloy conductor cable for photovoltaic power transmission, comprising a support seat 11, a line feeder frame 15 is connected to the top of the support seat 11, a hook 13 is installed at the top of the line feeder frame 15, a wire tube 14 is embedded in the inside of the line feeder frame 15, a cable body 18 is embedded in the inside of the wire tube 14, a support frame 12 is connected to the top of the support seat 11, an adjusting frame 16 is connected to the top of the support frame 12, a positioning wheel 17 is embedded in the inside of the adjusting frame 16, the support frame 12 and the adjusting frame 16 are rotatably connected, a rotating shaft is arranged between the two, the adjusting frame 16 rotates to drive the positioning wheel 17, thereby changing the deflection angle of the positioning wheel 17.

[0023] The traditional way of laying out cables mainly relies on simple spool supports and manual operation. Usually the cable is wound around a spool, and then the spool is set up on a simple support or roller device, and the cable is laid directly from the spool by manpower. In some more complex construction sites, some basic lifting equipment or ropes may be used to assist in moving the spool, but in general, this traditional way of laying out cables is difficult to handle when faced with some large cables. Due to the heavy weight and hardness of the cables themselves, the required pulling force is very large, which not only easily fatigues the operators but also reduces work efficiency. In order to solve this problem, the transmission component 2, the protection component 3, the pushing component 4 and the meshing component 5 are designed to save effort when laying out the cables. The specific operation is as follows: The upper surface of the support seat 11 is also connected to the transmission component 2, and the transmission component 2 includes a wrapping bin 21, The upper surface of the support seat 11 is connected to a wrapping bin 21, the top of the wrapping bin 21 is movably connected to a limit plate 22, a threading wheel 23 is arranged on the inner side of the limit plate 22, the limit plate 22 and the support seat 11 are rotatably connected, the top of the wrapping bin 21 is connected to a through slot 24, a sliding sheet 25 is embedded in the through slot 24, a pressing roller 26 is connected to the top of the sliding sheet 25, the cable body 18 is pulled out from the pay-off wheel, first passes through the inside of the wire tube 14, then is transported to the threading wheel 23 through the positioning wheel 17, and finally is transported to the pressing roller 26 through the threading wheel 23, so that the cable is pulled out from the pressing roller 26 ; During the transmission process of the cable, the cable body 18 is embedded in the inside of the wire tube 14. After being embedded in the inside of the wire tube 14, it passes between the two positioning wheels 17, and finally passes through the limit plate 22 and the threading wheel 23 to the inside of the crimping roller 26. When the cable is embedded in the inside of the crimping roller 26, the end of the cable body 18 is also clamped by the crimping roller 26. In this way, the movement of the crimping roller 26 can drive the movement of the cable body 18, thereby realizing the function of releasing the wire; in order to make the operation of releasing the wire easier to control, when the cable body 18 is pulled, when the cable body 18 passes through the threading wheel 23, The threading wheel 23 is driven to rotate, so that when facing some heavier cables, the threading wheel 23 can play a supporting role, and the friction between the threading wheel 23 and the cable body 18 is reduced by rotation, making the transmission easier. When the threading wheel 23 stops rotating, due to the large mass of the cable body 18, the friction between the cable body 18 and the threading wheel 23 will become larger, and the cable body 18 will be difficult to be pulled. The rotation of the limit plate 22 and the threading wheel 23 can control the speed of paying out the cable body 18, thereby avoiding a series of dangers caused by excessive paying out speed.

[0024] The support seat 11 is provided with a protection assembly 3, which includes a slide rail 31, a telescopic rod 32 is embedded in the slide rail 31, one side of the telescopic rod 32 is connected to the limit plate 22, the top of the telescopic rod 32 is connected to the connecting plate 34, the top of the connecting plate 34 is connected to the limit plate 22, a brake pad 35 is provided on the side of the support seat 11 close to the limit plate 22, a spring 33 is connected to the outer surface of the telescopic rod 32, a side of the telescopic rod 32 away from the connecting plate 34 is embedded in the slide rail 31, and the connecting plate 34 and the slide rail 31 are connected. 1; regarding the rotation and stopping of the limit plate 22 and the threading wheel 23, the brake pad 35 is used to inhibit them. When the telescopic rod 32 begins to shrink, it drives the connecting plate 34 to move toward one side of the support seat 11. When the connecting plate 34 moves, it also drives the limit plate 22 and the threading wheel 23 to move. When the outer side of the limit plate 22 contacts the brake pad 35, the two rub against each other. The friction between the brake pad 35 and the limit plate 22 is used to further inhibit the rotation of the limit plate 22.

[0025] Considering the large diameter and heavy weight of large cables, when laying out the cables, workers often need multiple workers to lift the cables and pull them forward. This laying out work is very difficult. In order to solve this problem, the pulley 44 is rotated by an external handle, and the rotation of the pulley 44 further drives the cable body 18 forward. In the whole operation process, it is very labor-saving and saves more physical strength. The specific operation is as follows: a pushing component 4 is embedded in the wrapping bin 21, and the pushing component 4 includes a fixed pulley 41. The fixed pulley 41 is installed inside the wrapping bin 21. There are two groups of fixed pulleys 41. A movable pulley 43 is also embedded in the parcel bin 21, and a cable 42 is connected to the fixed pulley 41. The cable 42 is firstly wound around the movable pulley 43, and then is wound around the first set of fixed pulleys 41 through the movable pulley 43, and then is wound around the second set of fixed pulleys 41 through the first set of fixed pulleys 41. A pulley 44 is also installed inside the parcel bin 21, and two sets of pulleys 44 are provided. A transmission belt 45 is wound around the outer surface of the pulley 44, and the transmission belt 45 is sleeved on the two sets of pulleys 44. A pushing block 48 is connected to the transmission belt 45. An engaging block 47 is connected to the side of the movable pulley 43 away from the parcel bin 21. The cable 42 is firstly wound around the movable pulley 43, and then is wound around the first set of fixed pulleys 41, and then is wound around the second set of fixed pulleys 41 through the first set of fixed pulleys 41. One end of 42 is connected to the fixed pulley 41, and the other end is connected to the connecting block 46. The connecting block 46 is connected to the transmission belt 45. The movable pulley 43 is embedded in the slide groove provided on the inner wall of the parcel bin 21. The movable pulley 43 is slidably connected to the slide groove. The rotation of the pulley 44 drives the transmission belt 45. When the transmission belt 45 rotates, it drives the connecting block 46 to pull the cable 42. After the cable 42 is pulled, it drives the movable pulley 43 to slide in the slide groove. When the pulley 44 rotates in the opposite direction, it drives the rotation of the transmission belt 45, thereby pushing the block 48 to contact the meshing block 47, and the pushing block 48 pushes the meshing block 47 to move. The meshing assembly 5 is embedded in the crimping roller 26, and the meshing assembly 5 includes a ratchet rod 53, and the ratchet rod 53 is embedded in the crimping roller 26. When the crimping roller 26 rotates clockwise, it is rotatably connected with the ratchet rod 53, and when the crimping roller 26 rotates counterclockwise, it meshes with the ratchet rod 53. A fixing rod 54 is connected to the ratchet rod 53, and the fixing rod 54 is fixedly connected to the sliding sheet 25. A ratchet 51 is installed inside the crimping roller 26, and the ratchet 51 and the crimping roller 26 are movably connected. A support spring 52 is also provided inside the crimping roller 26, and the support spring 52 is connected between the ratchet 51 and the inner wall of the crimping roller 26;When the cable body 18 is clamped between the pressing rollers 26, the movement of the pressing rollers 26 can drive the movement of the cable body 18, and the rotation of the pulley 44 drives the connecting block 46 to rotate. When the connecting block 46 moves, it drives the cable 42 to move. When the cable 42 moves, the fixed pulley 41 starts to rotate. When the fixed pulley 41 rotates, it drives the movable pulley 43. At this time, as the cable 42 is pulled, the movable pulley 43 slides in the slide groove opened in the wrapping bin 21, and the sliding of the movable pulley 43 drives the sliding plate 25 to move. When the sliding plate 25 moves, it drives the pressing roller 26 to move forward, thus realizing the function of the cable body 18 to output the line. Due to the mutual cooperation between the fixed pulley 41, the cable 42 and the movable pulley 43, the direction of the force is changed by the fixed pulley 41, and the force is reduced by the movable pulley 43. Since the tension at each part of the cable 42 is equal, the tension of each section of the cable 42; , thereby achieving the effect of saving effort, and it can also be easier to pull a cable with a larger mass; when the movable pulley 43 slides to the end of the slide groove, the pulley 44 is rotated in the opposite direction, so that the pulley 44 drives the transmission belt 45 to move, and at this time the connecting block 46 will also move with it. Since the cable 42 is made of flexible material, the cable 42 cannot push the movable pulley 43 to reset. At this time, the movable pulley 43 can be reset by the pushing block 48. When the transmission belt 45 rotates, it drives the pushing block 48 to move. When the pushing block 48 moves, it contacts the meshing block 47. At this time, the pushing block 48 will push the meshing block 47 to move, thereby resetting the movable pulley 43; in order to avoid the cable body 18 being pulled again during resetting, this problem is solved by setting the meshing component 5.

[0026] Combination Fig.10As shown, the rotation of the crimping roller 26 is unidirectional. For example, when the cable body 18 needs to be released, the cable body 18 needs to be limited by the crimping roller 26. That is to say, when the sliding piece 25 moves to the right, the force drives the crimping roller 26 to rotate counterclockwise. In order to overcome the rotation of the crimping roller 26, the ratchet 51 inside the crimping roller 26 will be firmly engaged on the ratchet rod 53. Because the ratchet rod 53 and the fixed rod 54 are fixedly connected, the ratchet rod 53 and the crimping roller 26 cannot rotate. At this time, the crimping roller 26 can The cable body 18 can be clamped better. Conversely, when the movable pulley 43 needs to be reset, in order to prevent the movement of the sliding piece 25 from affecting the cable body 18, it is necessary to release the limiting relationship between the wire-pressing roller 26 and the cable body 18. That is to say, when the sliding piece 25 moves to the left, the wire-pressing roller 26 needs to roll on the outer surface of the cable body 18. When the wire-pressing roller 26 rotates clockwise, the support spring 52 cannot be engaged with the support spring 52. At this time, the movement of the sliding piece 25 cannot affect the cable body 18, thereby realizing the wire-releasing operation of the cable body 18.

[0027] When the wire-crimping roller 26 needs to rotate counterclockwise, the tooth tip of the ratchet 51 will be stuck on the edge of the tooth groove of the ratchet rod 53. At this time, the ratchet 51 and the ratchet rod 53 are meshed, so that the ratchet 51 cannot be disengaged from the ratchet rod 53, thereby preventing the wire-crimping roller 26 from rotating, and thus achieving the function of limiting the cable body 18. When the wire-crimping roller 26 needs to rotate clockwise, the ratchet 51 will be lifted up and jump over a tooth groove under the push of the ratchet rod 53 for each rotation of one tooth pitch, and then fall down and mesh with the next tooth groove, so that meshing cannot be performed, and the cable body 18 cannot be limited.
