[0001] The invention belongs to the technical field of electric power construction, and in particular is an electric power construction traction device. Background Art

[0002] At present, the process of power construction usually involves the laying of power cables. Most of the existing power cables are installed on the outside of the wire storage roller by winding. The power cables are wound in an orderly manner outside the wire storage roller. When the laying of the power cable is required, the wire storage roller is controlled to rotate by the driving mechanism to unwind the power cable. At the same time, the staff pulls one end of the power cable to pull the power cable to a distant place so that the power cable can be fully unfolded.

[0003] When the wire storage roller rotates, the power cable is gradually unwound from one end of the wire storage roller to the other end. During this process, the unwound power cable will swing as the unwound position changes, thereby generating lateral friction with the unwound power cable on the wire storage roller, which in turn causes the power cable to be easily worn.

DETAILED DESCRIPTION

[0036] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] See also Figure 1 The present embodiment provides an electric power construction traction device, including a base plate 10, a wire storage roller 20, a first drive assembly 30, a second drive assembly 40 and a wire moving assembly 50. The wire storage roller 20 is rotatably mounted on the upper part of the base plate 10, and the wire moving assembly 50 is arranged on one side of the wire storage roller 20. The second drive assembly 40 is arranged on the side of the wire storage roller 20, and is used to drive the wire storage roller 20 to rotate to unwind the cable. The first drive assembly 30 is arranged on the upper part of the base plate 10. When the wire storage roller 20 rotates to unwind the cable, the first drive assembly 30 is used to drive the wire moving assembly 50 to reciprocate along the length direction of the wire storage roller 20.

[0039] When it is necessary to unwind the power cable wound on the wire storage roller 20, the staff passes one end of the cable through the wire moving assembly 50 and then pulls the cable. At this time, the second drive assembly 40 drives the wire storage roller 20 to rotate to unwind the wound cable. When the wire storage roller 20 unwinds the cable, the cable changes continuously from the unwinding position on the wire storage roller 20 from right to left and from left to back. At this time, the first drive assembly 30 can be used to drive the wire moving assembly 50 to move back and forth along the length direction of the wire storage roller 20, so that the wire moving assembly 50 always moves with the unwinding position of the cable, thereby avoiding lateral friction between the unwound cable and the unwound cable, and preventing the cable from being worn.

[0040] See also Figure 1 , Figure 2 as well as Figure 3 In one embodiment, two groups of second support plates 102 are fixedly arranged on the upper part of the bottom plate 10, and a square guide rod 103 is fixedly arranged between the two groups of second support plates 102. The first driving assembly 30 includes a motor 301, a driving shaft 302 and a driving roller 303. The motor 301 is fixedly installed on the side wall of one group of the second support plates 102, and the driving roller 303 is arranged between the two groups of the second support plates 102. The driving roller 303 is located below the square guide rod 103. The driving roller 303, the square guide rod 103 and the wire storage roller 20 are parallel to each other. The side wall of the driving roller 303 is provided with a first spiral groove 30 4 and a second spiral groove 305, the first spiral groove 304 and the second spiral groove 305 have opposite rotation directions, the first spiral groove 304 and the second spiral groove 305 are connected end to end, one end of the driving shaft 302 is connected to the output end of the motor 301, and the other end is connected to the driving roller 303, the line moving assembly 50 includes a line moving rod 501, a guide sleeve 503 and a square sleeve 504, the square sleeve 504 is slidably sleeved on the outside of the square guide rod 103, one end of the line moving rod 501 is fixedly connected to the square sleeve 504, and the other end extends to the inside of the first spiral groove 304, and the guide sleeve 503 is arranged on one side of the line moving rod 501.

[0041] Initially, one end of the power cable on the wire storage roller 20 is located at the left end of the wire storage roller 20, the wire shifting rod 501 and the guide sleeve 503 are synchronously located at the left end of the driving roller 303, and the end of the wire shifting rod 501 away from the square sleeve 504 extends to the inside of the first spiral groove 304. The staff passes one end of the power cable through the inside of the guide sleeve 503 and pulls the power cable. The second driving component 40 drives the wire storage roller 20 to rotate to unwind the cable. When the cable is unwinding, the motor 301 drives The driving shaft 302 rotates, thereby driving the driving roller 303 to rotate. At this time, the first spiral groove 304 rotates along with the driving roller 303, thereby pushing the wire-shifting rod 501 so that the wire-shifting rod 501 drives the guide sleeve 503 to move rightward along the length direction of the wire storage roller 20. At the same time, the square sleeve 504 slides to the right along the square guide rod 103. When the guide sleeve 503 moves to the right, the traction cable moves to the right synchronously. When the cable is unwound from the left end position of the wire storage roller 20 to the right end position, the wire-shifting rod 501 slides to The rightmost end of the first spiral groove 304, thereafter, as the driving roller 303 continues to rotate, the wire moving rod 501 slides from the rightmost end of the first spiral groove 304 into the second spiral groove 305. Since the second spiral groove 305 rotates in the opposite direction to the first spiral groove 304, the second spiral groove 305 can push the wire moving rod 501 so that the wire moving rod 501 drives the guide sleeve 503 to move leftward along the length direction of the wire storage roller 20. At the same time, the square sleeve 504 slides leftward along the square guide rod 103. When the guide sleeve 503 slides leftward, the traction cable moves leftward synchronously; through the above-mentioned guide sleeve 503 reciprocating left and right along the length direction of the wire storage roller 20, the wire storage roller 20 can adaptively pull the cable left and right when unwinding the cable, so that the cable located between the guide sleeve 503 and the wire storage roller 20 can always maintain a vertical state with the wire storage roller 20, thereby avoiding lateral friction between the cable unwound from the wire storage roller 20 and the unwound cable, thereby improving the protection of the cable during the wire unwinding process.

[0042] See also Figure 1 In one embodiment, a sliding sleeve 502 is slidably provided on the outside of the wire shifting rod 501, and one side of the sliding sleeve 502 is rotatably connected to the guide sleeve 503 through a rotating rod.

[0043] When the cable is pulled manually, as the person gradually moves away from the wire storage roller 20, the angle between the cable and the wire storage roller 20 will gradually change. At this time, the cable can drive the guide sleeve 503 to make the sliding sleeve 502 adaptively slide along the outside of the wire shifting rod 501. At the same time, the guide sleeve 503 adaptively rotates compared to the sliding sleeve 502. Through the sliding of the sliding sleeve 502 and the rotation of the guide sleeve 503, when the cable is gradually pulled away from the wire storage roller 20, it can prevent the cable from bending at an excessive angle, thereby achieving further protection when the cable is released.

[0044] See also Figure 1In one embodiment, two groups of first support plates 101 are fixedly provided on the upper part of the base plate 10, the wire storage roller 20 is arranged between the two groups of first support plates 101, and a rotating shaft 201 is fixedly provided at the end of the wire storage roller 20, and the end of the rotating shaft 201 away from the wire storage roller 20 is rotatably connected to the first support plate 101, and the second driving component 40 includes a first pulley 401, a driving belt 402 and a second pulley 403, the first pulley 401 is fixedly provided on the outside of the driving shaft 302, the second pulley 403 is fixedly provided on the outside of the rotating shaft 201, one end of the driving belt 402 is sleeved on the outside of the first pulley 401, and the other end is sleeved on the outside of the second pulley 403.

[0045] When the motor 301 drives the driving shaft 302 to rotate and then drives the driving roller 303 to rotate, the driving shaft 302 can also drive the first pulley 401 to rotate. The transmission action of the driving belt 402 can drive the second pulley 403 and the rotating shaft 201 to rotate, and then drive the wire storage roller 20 to rotate. When the wire storage roller 20 rotates, the power cable is unwound.

[0046] As can be seen from the foregoing, the first spiral groove 304 and the second spiral groove 305 have opposite rotation directions, so there is bound to be an intersection between the first spiral groove 304 and the second spiral groove 305 outside the driving roller 303. When one end of the wire-shifting rod 501 slides along the inside of the first spiral groove 304 to the intersection with the second spiral groove 305 or one end of the wire-shifting rod 501 slides along the inside of the second spiral groove 305 to the intersection with the first spiral groove 304, in order to prevent one end of the wire-shifting rod 501 from sliding from the inside of the first spiral groove 304 to the inside of the second spiral groove 305 or from sliding from the inside of the second spiral groove 305 to the inside of the first spiral groove 304, please refer to Figure 2 and Figure 3 In one embodiment, a limiting assembly 306 is provided at the intersection of the first spiral groove 304 and the second spiral groove 305. When one end of the wire moving rod 501 slides to the intersection of the first spiral groove 304 and the second spiral groove 305, the limiting assembly 306 is used to limit the wire moving rod 501 to slide forward along the current spiral groove.

[0047] See also Figure 4 as well as Figure 5In one embodiment, the limiting assembly 306 includes a pressing plate 3061, a piston column 3062, a first air channel 3063, a limiting block 3065, a groove 3066 and a second air channel 3067. The pressing plate 3061 is provided with two groups, one end of the two groups of pressing plates 3061 is respectively hingedly connected to the bottom wall of the first spiral groove 304 and the second spiral groove 305, and the other end is respectively extended to the intersection of the first spiral groove 304 and the second spiral groove 305. The first air channel 3063 is provided with two groups, and the two groups of the first air channel 3063 are respectively opened at the inner bottom of the first spiral groove 304 and the second spiral groove 305. The two groups of the first air channels 3063 are respectively located below the two groups of the pressing plates 3061. The piston column 3062 is provided with two groups, one end of the two groups of the piston column 3062 is respectively attached to the bottom of the two groups of the pressing plates 3061, and the other end is respectively extended to To the inside of the two groups of the first air channels 3063, the inside of the two groups of the first air channels 3063 is also provided with an elastic member 3064 for providing elastic support to the piston column 3062, the grooves 3066 are provided with two groups, and the two groups of the grooves 3066 are respectively opened at the inner bottom of the first spiral groove 304 and the second spiral groove 305, the limit blocks 3065 are provided with two groups, and the two groups of the limit blocks 3065 are respectively embedded in the two groups of the grooves 3066, the second air channels 3067 are provided with two groups, and the two groups of the second air channels 3067 are opened in the driving roller 303, one end of one group of the second air channels 3067 is connected with one group of the grooves 3066, and the other end is connected with one group of the first air channels 3063, and one end of the other group of the second air channels 3067 is connected with another group of the grooves 3066, and the other end is connected with another group of the first air channels 3063.

[0048] When one end of the wire moving rod 501 slides along the first spiral groove 304 to the intersection with the second spiral groove 305, the end of the wire moving rod 501 acts on the pressure plate 3061 inside the first spiral groove 304, and the pressure plate 3061 rotates downward under pressure, thereby pressing a group of piston columns 3062 below it into the corresponding first air channel 3063. The piston columns 3062 pressurize the air inside the corresponding first air channel 3063 to the corresponding groove 3066 through the corresponding second air channel 3067, thereby pushing the corresponding limit block 3065 to move upward. When the limit block 3065 moves upward, it extends into the second spiral groove 305, thereby closing the second spiral groove 305 to prevent One end of the wire-stopping rod 501 slides into the second spiral groove 305 from the intersection of the first spiral groove 304 and the second spiral groove 305, thereby ensuring that one end of the wire-moving rod 501 can continue to slide forward along the current first spiral groove 304, thereby ensuring that the wire-moving rod 501 can smoothly drive the guide sleeve 503 to move rightward along the length direction of the wire storage roller 20. After one end of the wire-moving rod 501 passes through the intersection of the first spiral groove 304 and the second spiral groove 305, the corresponding elastic member 3064 can push the piston column 3062 so that the piston column 3062 moves in the opposite direction along the corresponding first airway 3063, thereby lifting the corresponding pressure plate 3061 to achieve the reset of the pressure plate 3061.

[0049] When one end of the wire moving rod 501 slides along the second spiral groove 305 to the intersection with the first spiral groove 304, the end of the wire moving rod 501 acts on the pressure plate 3061 inside the second spiral groove 305, and the pressure plate 3061 rotates downward under pressure, thereby pressing a group of piston columns 3062 below it into the corresponding first air channel 3063. The piston columns 3062 pressurize the air inside the corresponding first air channel 3063 to the corresponding groove 3066 through the corresponding second air channel 3067, thereby pushing the corresponding limit block 3065 to move upward. When the limit block 3065 moves upward, it extends into the first spiral groove 304, thereby closing the first spiral groove 304 to prevent One end of the stop wire rod 501 slides from the intersection of the second spiral groove 305 and the first spiral groove 304 into the first spiral groove 304, thereby ensuring that one end of the wire moving rod 501 can continue to slide forward along the current second spiral groove 305, and then ensuring that the wire moving rod 501 can smoothly drive the guide sleeve 503 to move left along the length direction of the wire storage roller 20. After one end of the wire moving rod 501 passes through the intersection of the second spiral groove 305 and the first spiral groove 304, the corresponding elastic member 3064 can push the piston column 3062 so that the piston column 3062 moves in the opposite direction along the corresponding first airway 3063, and then lifts the corresponding pressure plate 3061 to achieve the reset of the pressure plate 3061.

[0050] In one embodiment, the elastic member 3064 may be a spring or a metal spring, which is not limited here.

At this time, the second driving assembly 40 drives the wire storage roller 20 to rotate to unwind the wound cable. When the wire storage roller 20 unwinds the cable, the cable changes continuously from the unwinding position on the wire storage roller 20 from right to left and from left to back. At this time, the first driving assembly 30 can be used to drive the moving wire assembly 50 to move back and forth along the length direction of the wire storage roller 20, so that the moving wire assembly 50 always moves with the unwinding position of the cable, thereby avoiding lateral friction between the unwound cable and the unwound cable, and preventing the cable from being worn. Compared with the prior art, during the unwinding process of the power construction cable, it can effectively prevent the unwound cable and the unwound cable from being damaged due to lateral friction, thereby improving the protection of the cable when unwinding.
