The fine steel wire rope is connected with the thick steel wire rope, and finally connected with the conductor. Under the action of the traction machine, the conductor follows the fine steel wire rope and the thick steel wire rope through the wire laying pulley, and then the insulator and other electric power fittings are connected. In the process of wire laying, the worker can realize wire laying by pulling the wire laying vehicle. However, in the process of pulling the wire laying vehicle, sudden conditions may exist in the wire laying section, forcing the traction vehicle to change speed or stop suddenly.

The two limiting plates arranged on the bottom plate and the wire guide wheels slidingly arranged on the limiting plates are provided, so that when a worker is leading a wire, the cable is wound on the two wire guide wheels, when the traction vehicle suddenly changes the speed, the spring connected between the sliding block and the bottom end of the sliding groove keeps the cable on the two wire guide wheels in a tense state, and the cable is prevented from being damaged due to sudden stress change.

[0037] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings of the specification and specific embodiments.

[0038] Referring to Figure 1 A pay-off mechanism comprises a positioning bottom plate 1, a supporting unit 2, a wire leading unit 3 and a buffer unit 4 are fixedly arranged on the positioning bottom plate 1.

[0039] The supporting unit 2 comprises two groups of supporting assemblies, each group of supporting assemblies comprises a supporting rod one 21 fixedly arranged on the bottom plate 1 and a supporting rod two 22 rotationally arranged on the bottom plate 1, a rotating shaft 5 is rotationally arranged between the supporting rod one 21 and the supporting rod two 22, and the rotating shaft 5 is fixedly arranged with a winding drum 6.

[0040] Referring to Figures 1-2 A placing groove 23 is formed in the top end of the supporting rod one 21 and the supporting rod two 22, the rotating shaft 5 on the winding drum 6 is placed on the placing groove 23 on the supporting rod two 22 after the device is installed and fixed, the top end of the supporting rod one 21 is arranged in an arc shape, a pneumatic cylinder 24 is rotationally arranged on the bottom plate 1, and the output end of the pneumatic cylinder 24 is rotationally connected with the supporting rod two 22, the top end of the supporting rod one 21 is arranged in an arc shape, so that the pneumatic cylinder 24 can be used to drive the supporting rod two 22 to rotate in the process of controlling the extension and contraction of the pneumatic cylinder 24, the rotating shaft 5 placed on the supporting rod two 22 can smoothly slide in the placing groove 23 of the supporting rod one 21, the friction between the rotating shaft 5 and the placing groove 23 of the supporting rod one 21 is reduced, and the protection function of the rotating shaft 5 is realized, and the distance from each position of the top end of the supporting rod one 21 to the rotationally connected position of the supporting rod two 22 and the bottom plate 1 is equal, the replacement of the winding drum 6 can be realized by controlling the extension and contraction of the pneumatic cylinder 24 to drive the supporting rod two 22 to rotate, which is simple and convenient, the step of manually disassembling the traditional pay-off vehicle when the winding drum 6 is replaced is omitted, and the replacement efficiency is improved.

[0041] Referring toFigures 1-3 The plurality of clamping rings 7 are fixedly arranged on the rotating shaft 5, which facilitates the installation of the winding disc 6 by the staff, avoids the deviation of the horizontal position of the rotating shaft 5 when the winding disc 6 is installed and clamped on the support rod two 22, and facilitates the positioning of the rotating shaft 5 during installation. Each clamping ring 7 is located between the support rod one 21 and the support rod two 22. The clamping plate lower jaw 8 is fixedly arranged on the support rod one 21. The clamping plate upper jaw 9 is rotatably arranged on the clamping plate lower jaw 8. The rotating shaft 5 is located between the clamping plate lower jaw 8 and the clamping plate upper jaw 9. The clamping plate lower jaw 8 and the clamping plate upper jaw 9 arranged on the support rod one 21 can prevent the cable on the winding disc 6 from being loosened and disordered when the cable is continuously discharged from the winding disc 6 due to inertia during the emergency stop of the cable laying vehicle. The staff can stop the rotation of the winding disc 6 by touching the side wall of the winding disc 6 without the aid of tools. The staff's palm can be injured due to the great friction between the side wall of the winding disc 6 and the palm even if the staff wears protective gloves. In order to avoid this situation, the staff only needs to pull the clamping plate upper jaw 9 when emergency stop is needed. The inner wall of the clamping plate upper jaw 9 is in contact with the rotating shaft 5, and the rotating speed of the rotating shaft 5 is reduced until it stops. The whole process is safe and simple.

[0042] The lead unit 3 includes two support plates 31 fixedly arranged on the bottom plate 1.

[0043] Referring to Figures 3-5 The wire bundler 61 is fixedly arranged on the rotating shaft 5 in the winding disc 6. The inner wall of the wire bundler 61 is rough. The wire bundler 61 arranged on the rotating shaft 5 and the winding disc 6 facilitates the fixation of the cable on the winding disc 6.

[0044] The buffer unit 4 includes a first limiting plate 41 and a second limiting plate 421 fixedly arranged on the bottom plate 1. Two wire guide wheels 42 are movably arranged on the first limiting plate 41. The second limiting plate 421 is provided with a structure for preventing the cable from being separated from the wire guide wheel 42.

[0045] Referring to Figures 6-8The anti-falling structure comprises two pressing rods 411 slidingly arranged on the limiting plate 421, and an arc-shaped pressing plate 412 fixedly arranged on the two pressing rods 411, a plurality of rollers 413 are rotationally arranged on the pressing plate 412, the rollers 413 are in contact with the surface of the wire guide wheel 42, the limiting plate 41 is provided with a control module for controlling the horizontal movement of the pressing rod 411, when the wire laying vehicle suddenly changes speed during the wire laying process, the speed of the winding reel 6 is difficult to change in a short time, so that the cable on the two wire guide wheels 42 is too tight or loose, and the cable may fall off the wire guide wheel 42, by arranging the pressing rod 411 on the limiting plate 421 and the control module for controlling the movement of the pressing rod 411, after the cable is pulled by the staff, the plurality of rollers 413 on the pressing rod 411 can press the cable on the wire guide wheel 42, so that the cable attached to the wire guide wheel 42 will not fall off.

[0046] With reference to Figure 4 The opening and closing size of the pressing plate 412 is smaller than the diameter of the wire guide wheel 42, when the cable is wound on the two wire guide wheels 42, the cable will be in contact with the two outward walls of the wire guide wheel 42, when the speed of the wire laying vehicle changes, the degree of contact between the cable and the two side walls of the wire guide wheel 42 will also decrease, in order to avoid the cable from falling off, the pressing plate 412 is used to press the cable, so it is only necessary to press the cable on the outer side wall of the wire guide wheel 42, which is simple and effective.

[0047] A sliding groove 43 is formed in the limiting plate 41, a sliding block 44 is slidingly arranged on the sliding groove 43, and the wire guide wheel 42 is rotationally connected between the sliding block 44 and the bottom end of the sliding groove 43, and a spring 45 is fixedly arranged between the sliding block 44 and the bottom end of the sliding groove 43, when the speed of the wire laying vehicle changes suddenly during the wire laying process, when the speed of the wire laying vehicle suddenly decreases or stops suddenly, the wire laying speed of the wire laying vehicle decreases, but the rotating speed of the winding reel 6 cannot be adjusted in a short time, so that the wire laying speed does not change, the cable appears to be loose, and the tension between the cables on the two wire guide wheels 42 decreases, so that the pressure on the sliding block 44 slidingly arranged on the sliding groove 43 decreases, the spring 45 pushes the sliding block 44 to move outward, until the tension between the cables on the two wire guide wheels 42 is equal to the elastic force of the spring 45, so that the cable on the wire laying vehicle is in a tense state, when the wire laying vehicle suddenly accelerates, the wire laying speed of the wire laying vehicle suddenly increases, the wire laying speed of the winding reel 6 does not change, so that the stress of the cable increases, the tension between the cables on the two wire guide wheels 42 increases, the spring 45 is compressed under stress, so that the distance between the two wire guide wheels 42 is shortened, which plays a certain buffering role on the cable, avoids the cable from being pulled off, and ensures the normal operation of the wire laying vehicle.

[0048] With reference to Figures 2-4Two cylinders 33 are arranged vertically on the bottom plate 1, two vertical plates are fixedly arranged on the bottom plate 1, and two shaft bodies 34 are rotatably arranged between the two vertical plates, and the shaft bodies 34 are perpendicular to the cylinders 33, because the cable on the reel 6 appears in a complex winding manner, the angle of the cable during the cable laying process will also change constantly, if the cable is directly pulled by the wire guide wheel 42 on the buffer unit 4, the cable may be derailed, the two cylinders 33 arranged on the bottom plate 1 correct the angle of the horizontal cable, and the two shaft bodies 34 on the vertical plate correct the vertical height of the cable, the corrected cable can slide out from the fixed position and be wound on the wire guide wheel 42, so that the cable on the wire guide wheel 42 does not derail during the operation of the cable laying vehicle, and the normal operation of the cable laying operation is ensured.

[0049] Referring to Figures 1-3 The gap between the shaft bodies 34, the gap between the cylinders 33 and the gap between the first wire rod 32 and the third wire rod 322 are at the same horizontal level, in order to enable the cable to be stably transmitted during the cable pulling process, the shaft bodies 34, the cylinders 33 and the first wire rod 32 and the third wire rod 322 are arranged at the same horizontal level, on the one hand, the initial pulling process is more convenient, and on the other hand, the friction loss between the cable and the cylinder 33 is reduced during the transmission process, and the damage to the cable is reduced.

[0050] Referring to Figures 4-6 Two supports 311 are fixedly arranged on the bottom plate 1, and a wire box 312 is fixedly arranged between the two supports 311, and the inside of the wire box 312 is arranged in a narrow middle and wide two ends, the horizontal height of the support 311 is greater than the height of the limiting plate 41, the wire box 312 arranged on the bottom plate 1 plays a certain guiding role for the cable, and the inside of the wire box 312 is arranged in a narrow middle and wide two ends, during the process of inserting the cable into the wire box 312, the protruding structure inside can reduce the included angle between the cable and the edge of the wire box 312, thereby achieving the purpose of reducing friction loss.

[0051] Working principle:

[0052] S1, during use, first fix the bottom plate 1 of the device and the cable laying vehicle by the staff, start the air cylinder 24 after fixing is completed, so that the air cylinder 24 pushes the support rod one 21 to rotate and separate from the support rod two 22, at this time the staff places the prepared reel 6 on the placing groove 23 on the support rod two 22, controls the air cylinder 24 to extend and retract, so that the support rod two 22 rotates until the reel 6 reaches the predetermined position.

[0053] S2, after the winding disc 6 is placed, the staff pulls the wire, the cable is connected through the wire rod 32 in the lead unit 3, and is wound on the wire wheel 42 on the buffer unit 4.

[0054] S3, in the process of using the device to pay off the wire, if the slope makes the speed of the wire paying-off vehicle suddenly increase, since the winding disc 6 on the supporting rod 21 cannot change the rotating speed in the first time, the stress of the cable winding will change greatly, the wire wheel 42 winding the cable will produce horizontal movement, the stress of the cable is reduced, the cable is prevented from being damaged, if the speed of the wire paying-off vehicle suddenly decreases during driving, the staff can control the lower jaw 8 of the clamping plate to clamp the rotating shaft 5, the rotating speed of the winding disc 6 is reduced, the winding disc 6 is prevented from paying off the cable continuously due to the influence of inertia when the wire paying-off vehicle suddenly decreases or stops, the cable is prevented from being disorderly, and the next work is affected.
