DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] Embodiment 1:

[0038] Reference Figure 1-Figure 8A wire-paying device for installing electric power equipment comprises a wire-paying frame 1, a bottom of which is provided with walking wheels 2 so as to facilitate moving the wire-paying frame 1 to a specified position, and further comprises: a wire-paying unit arranged on the wire-paying frame 1, for paying out the cable; a straightening unit arranged on the wire-paying frame 1, for straightening the cable when paying out the cable, wherein the straightening unit is electrically connected to the wire-paying unit for adjusting the paying-out speed of the wire-paying unit; a cleaning mechanism 21 arranged on the straightening unit, and the straightening unit can drive the cleaning mechanism 21 to rotate in the opposite direction of the paying-out direction of the cable.

[0039] Reference Figure 1 and Figure 7 The pay-off unit includes a hydraulic rod 3 fixedly connected to the pay-off frame 1, the output end of the hydraulic rod 3 is fixedly connected to an adjusting plate 4 slidingly connected to the pay-off frame 1, a limit seat 5 is arranged on the adjusting plate 4, a driving motor 6 is fixedly connected to the limit seat 5, a pay-off wheel 7 is rotatably connected to the limit seat 5, and a wire drum 8 is arranged on the pay-off wheel 7, wherein a group of pay-off wheels 7 are connected to the output end of the driving motor 6, and the axis of the wire drum 8 and the pay-off wheel 7 are tightly fitted.

[0040] The specific structure of the wire drum 8 can refer to the technical solutions in the prior art. Those skilled in the art will know it and will not elaborate on it here. By adjusting the extension length of the hydraulic rod 3, it can be suitable for the use of wire drums 8 of different sizes. When the axis of the wire drum 8 is located on the pay-off wheel 7, the pay-off wheel 7 is driven to rotate by the driving motor 6. Under the action of friction, the wire drum 8 can be driven to rotate, thereby realizing the pay-off of the cable. By adjusting the rotation speed of the driving motor 6, the pay-off speed of the cable can be adjusted.

[0041] Reference Figure 1 , Figure 2 and Figure 4 The straightening unit includes a bracket 9 detachably connected to the pay-off frame 1, a fixed plate 10 is provided on the side of the bracket 9 close to each other, and a slide groove 11 is symmetrically opened on the side of the fixed plate 10 close to each other, a slider 12 is slidably connected inside the slide groove 11, an adjustment component 13 and a first spring 14 are fixedly connected between the slider 12 and the slide groove 11, and multiple groups of support rods 15 are fixedly connected to the slider 12 and the fixed plate 10. The first positioning wheel 16 is rotatably connected to the two groups of support rods 15 on the side away from the wire drum 8, and the second positioning wheel 17 is rotatably connected to the two groups of support rods 15 on the side close to the wire drum 8, wherein the first spring 14 is sleeved on the adjusting component 13, and the second positioning wheel 17 is close to the slider 12. The distance between the first positioning wheel 16 or the second positioning wheel 17 matches the size of the cable, and the support rod 15 adopts a retractable structure.

[0042] When the cable is paid out, the cable passes through the second positioning wheel 17 and the first positioning wheel 16 in sequence. When the cable is installed, the portion of the cable between the first positioning wheel 16 and the second positioning wheel 17 is in a taut state, thereby straightening the bent portion of the cable to facilitate installation of the cable, and the tighter the cable is, the greater the pressure between the cable and the second positioning wheel 17, thereby driving the slider 12 to move in the slide groove 11. In addition, the size of the support rod 15 can adapt to the size of the cable drum 8, and when the cable is paid out, the first positioning wheel 16 and the second positioning wheel 17 can move according to the displacement of the cable on the cable drum 8.

[0043] Reference Figure 4-Figure 5 The adjustment component 13 includes a sealing cylinder 131 and a compression rod 132, the compression rod 132 extends into the interior of the sealing cylinder 131, and an electric slip ring 133 is provided on the side of the compression rod 132 close to the sealing cylinder 131, and a variable resistance ring 134 is provided on the inner wall of the sealing cylinder 131, wherein the electric slip ring 133 and the variable resistance ring 134 are tightly fitted, and the variable resistance ring 134 and the electric slip ring 133 are electrically connected to the driving motor 6, and when the electric slip ring 133 moves into the interior of the sealing cylinder 131, the resistance connected to the driving motor 6 decreases.

[0044] The electric slip ring 133 and the variable resistance ring 134 are conventional means in the prior art and are therefore not described in detail. When the cable is tightened, the pressure between the cable and the second positioning wheel 17 will drive the compression rod 132 to move into the sealing tube 131, thereby reducing the resistance of the drive motor 6. While increasing the cable pay-off speed, on the one hand, it can prevent cable damage, and on the other hand, it can increase the cable installation speed. Moreover, when the compression rod 132 moves into the sealing tube 131, it can also compress the gas in the sealing tube 131.

[0045] Reference Figure 3 , also includes a mounting ring 18 fixedly connected to the support rod 15 on one side close to the first positioning wheel 16 and the second positioning wheel 17, a connecting rod 19 is fixedly connected between the two sets of mounting rings 18 close to the first positioning wheel 16 and the second positioning wheel 17, and a cleaning mechanism 21 is rotatably connected to the connecting rod 19, wherein the connecting rod 19 includes a fixed portion and a telescopic portion, the fixed portion is close to the second positioning wheel 17, the cleaning mechanism 21 is located on the fixed portion, a hollow shaft 20 penetrating the mounting ring 18 is fixedly connected to the second positioning wheel 17, and a linkage wheel 22 is fixedly connected to the hollow shaft 20 and the cleaning mechanism 21, and a belt 23 is sleeved between the linkage wheels 22 on the same side, wherein the linkage wheels 22 on the cleaning mechanism 21 and the linkage wheels 22 on the second positioning wheel 17 are cross-arranged.

[0046] During the straightening process of the cable, the cable fits tightly against the first positioning wheel 16 and the second positioning wheel 17, thereby driving the first positioning wheel 16 and the second positioning wheel 17 to rotate. The cross-setting of the interlocking wheels 22 can make the air storage cylinder 212 rotate in the opposite direction of the cable movement, thereby preventing the dust cleaned by the cleaning member 213 from continuing to move along the cable, and when the distance between the second positioning wheel 17 and the first positioning wheel 16 changes, the relative position between the cleaning member 213 and the cable will be adjusted, further improving the cleaning effect of the cleaning member 213 on the dust on the cable surface.

[0047] Reference Figure 3 and Figure 6 The cleaning mechanism 21 includes a rotating shaft 211 rotatably connected to the connecting rod 19, a gas cylinder 212 is fixedly connected to the rotating shaft 211, a plurality of cleaning members 213 are fixedly connected to the outer wall of the gas cylinder 212, and an exhaust hole 2111 is provided on a side of the gas cylinder 212 close to the cleaning member 213, wherein the cleaning member 213 is fitted with the cable, the sealing cylinder 131, the support rod 15 and the connecting rod 19 are connected to the gas cylinder 212 through a pipeline, and also includes a gravity column 214 arranged inside the gas cylinder 212, and the bottom of the gravity column 214 is rotatably connected to A movable wheel 215 and a hollow ring 2112 are fixedly connected to the interior of the exhaust hole 2111, a force-bearing rod 2113 is arranged inside the hollow ring 2112, a sealing member 2114 is fixedly connected to one end of the force-bearing rod 2113 close to the cleaning member 213, a second spring 2115 is fixedly connected between the sealing member 2114 and the inner wall of the exhaust hole 2111, wherein the size of the sealing member 2114 is larger than the size of the hollow ring 2112 and smaller than the size of the exhaust hole 2111, and the end of the force-bearing rod 2113 away from the sealing member 2114 extends to the interior of the air storage cylinder 212.

[0048] When the lengths of the sealing cylinder 131, the support rod 15 and the connecting rod 19 change, the compressed gas will enter the interior of the air cylinder 212. It should be explained that the gas can be passed into the air cylinder 212 through the air sliding ring. This is a conventional method in the prior art and will not be elaborated on. When the air cylinder 212 rotates, the gravity column 214 will always be located at the bottom of the air cylinder 212 under the action of its own gravity. The force-bearing rod 2113 is compressed by the movable wheel 215, so that the sealing member 2114 is separated from the hollow ring 2112, so that the gas inside the air cylinder 212 is blown toward the cable through the bottom, blowing off the dust cleaned by the cleaning member 213 and removing the dust adhering to the cleaning member 213.

[0049] Reference Figure 6, and also includes an arc-shaped member 216 fixedly connected to the side of the gravity column 214 close to the second positioning wheel 17, and a driving cylinder 217 is fixedly connected to the side of the arc-shaped member 216 close to the inner wall of the air storage cylinder 212, and a pressing plate 218 is fixedly connected to the output end of the driving cylinder 217, wherein the driving cylinder 217 is connected to the sealing cylinder 131 through a pipeline, and multiple groups of windshield plates 24 are fixedly connected to the outside of the second positioning wheel 17.

[0050] When the resistance encountered during cable installation is large, the second positioning wheel 17 is driven to move toward the first positioning wheel 16, the compression rod 132 is moved toward the inside of the sealing tube 131, and the compressed gas is delivered to the inside of the driving cylinder 217, driving the pressing plate 218 to move toward the force-bearing rod 2113, so that the gas in the gas storage cylinder 212 is blown toward the wind shield 24, further reducing the resistance encountered during cable installation.

[0051] Embodiment 2:

[0052] A method for laying out a wire using a wire laying device for installing electric power equipment, comprising the following steps:

[0053] Step 1: When installing the power equipment, push the cable to one side of the pay-off rack 1, adjust the size between the pay-off racks 1, and adjust the height of the pay-off unit to match the height of the cable, and push the cable onto the pay-off unit, while separating the cable from the ground;

[0054] The cable is wound on the wire drum 8, and the wire drum 8 can be pushed between the pay-off frames 1, and the position of the pay-off frames 1 can be adjusted by the running wheels 2;

[0055] Step 2: Pass the cable through the straightening unit and the cleaning mechanism 21 in sequence, release the cable through the wire-releasing unit, and install the end of the cable;

[0056] This can reduce the resistance of the cable during installation and prevent dust from affecting the connection between the cable and the power equipment;

[0057] Step 3: During the installation process, the straightening unit straightens the cable, and at the same time, the cleaning mechanism 21 cleans the dust on the surface of the cable;

[0058] Step 4: Control the cable pay-off speed according to the cable installation speed to ensure the cable installation efficiency while reducing the labor intensity of the staff;

[0059] Step 5: When the cable unwinding resistance is large, the cleaning mechanism 21 can reduce the resistance of the straightening unit, thereby achieving cable installation.
