Description

Technical Field

[0001] The present invention relates to the technical field of transmission line construction, and particularly relates to a continuous transmission line wire laying device and a wire laying method thereof. Background Art

[0002] Transmission lines are key components in the power system, responsible for efficiently and safely transmitting the electric energy generated by power plants to substations or user ends, connecting power plants far from the power consumption center, reducing the geographical limitations of energy transmission, interconnecting multiple isolated power grids, reducing the total installed capacity, and improving the unit efficiency and economy. During the construction of transmission lines, a special transmission line wire laying device is required, which is a special mechanical system for continuously unwinding and erecting coiled or looped wires and cables onto poles.

[0003] The above-mentioned existing technical solutions have the following defects: When laying wires during the construction of transmission lines, it is inconvenient to perform continuous wire laying work. It is necessary to stop and adjust the equipment multiple times, resulting in an interruption of the construction rhythm. It is necessary to spend additional time to re-prepare the equipment, reducing the degree of automation, further slowing down the progress, with low efficiency and extended construction period. Summary of the Invention

[0004] The purpose of the present invention is to provide a continuous transmission line wire laying device and a wire laying method thereof to solve the defect that the existing transmission line wire laying device is inconvenient for continuous wire laying.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: A continuous transmission line wire laying device and a wire laying method thereof, including a frame and a platform installed at one end thereof. Both sides of the top of the frame are installed with unwinding rollers. Disassembly and assembly structures are provided at one end of the frame. A sliding table is installed at the top of the platform, and rear traction machines are installed on both sides of the top of the sliding table. A front traction machine is provided at one end of the sliding table. An auxiliary structure is provided between the front traction machine and the rear traction machine; the auxiliary structure includes a bracket installed on the top of the platform, and movable shafts are installed on both sides of the bracket. First transmission gears are installed at the bottom ends of the movable shafts. Second transmission gears are provided at the top ends of the movable shafts, and pressing rods are provided at one ends of the rear traction machines at the top of the second transmission gears.

[0006] Preferably, transmission shafts are installed on both sides at one end of the frame, and the transmission shafts are rotatably connected to the frame. The transmission shafts are located at the central positions of the unwinding rollers.

[0007] Preferably, a lead screw is provided inside the sliding table, and a servo motor is installed on one side of the lead screw. Sliding seats are installed at the bottom ends of the rear traction machines, and the sliding seats are threadedly connected to the lead screw.

[0008] Preferably, drive gear sets are installed inside both the front tractor and the rear tractor, and connecting shafts are installed on both sides of the bottom of the front tractor.

[0009] Preferably, the disassembly and assembly structure includes a connecting plate hinged to one end of the frame, and buckles are hinged to the top of the connecting plate. Blocks are installed on the top of the frame at one end of each buckle, and a clamping structure is formed between the blocks and the buckles.

[0010] Preferably, first connecting gears are installed at the bottoms of the connecting shafts at one end of the first drive gears, and the first connecting gears and the first drive gears are meshed and connected. Second connecting gears are installed at the bottoms of the rear tractors at one end of the second drive gears, and the second connecting gears and the second drive gears are meshed and connected.

[0011] Preferably, the second drive gear is rotatably connected to the movable shaft. Blocks are installed on both sides of the top of the second drive gear, and tension springs are connected to one side of each block.

[0012] Preferably, a movable block is installed at the top of the movable shaft, and a return spring is arranged at the top of the movable block. The top of the movable block is trapezoidal, and a slider is arranged inside the movable block.

[0013] Preferably, chutes are arranged on the outer walls of the movable shafts outside the sliders, and a sliding structure is formed between the chutes and the sliders. A ratchet is arranged at the bottom of the movable block, and a clamping structure is formed between the ratchet and the block.

[0014] A preparation method for a continuous transmission line wire laying device includes the following steps:

[0015] S1. First, turn the connecting plate to contact the ground to form an inclined angle. When placing the unwinding roller inside the frame, the inclined angle of the connecting plate can play an auxiliary role to a certain extent. The unwinding roller is pushed along the connecting plate to the central position of the frame, and then the connecting plate is turned and merged with the frame, and the buckles and the blocks are clamped and fixed.

[0016] S2. Before restarting, the front tractor operates. Inside it, the traction of the wire is achieved through a transmission gear set. The first connecting gear below it meshes with the first transmission gear. The servo motor is started to drive the lead screw to rotate, and the two rear tractors above it are driven to translate through the slide base, so that one of the rear tractors is flush with the front tractor. While the rear tractor is moving, the second connecting gear below it is displaced to mesh with the second transmission gear. The second transmission gear is rotatably connected to the movable shaft. When the movable shaft rotates, the second transmission gear remains stationary. At the same time, the pressing rod at one end of the rear tractor squeezes the movable block, causing it to displace downward, so that a clamping is generated between the ratchet teeth and the abutting block, thereby driving the second transmission gear to rotate, causing the second connecting gear meshing with it to rotate simultaneously, and driving the rear tractor and the front tractor to work simultaneously;

[0017] S3. Stretch the wire to one end of the rear tractor, pay out the wire outward through the traction force. At the same time, pass the wire on the other pay-off reel through the other rear tractor, so that it is in the preparation stage. When the pay-out of this group of wires ends, immediately start the servo motor to drive the lead screw to work, translate this group of rear tractors to one side, and the other group of rear tractors are synchronously translated to a position flush with the front tractor. At the same time, the work of the rear tractor is realized through components such as gears, and the wire is pulled to the front tractor to continue paying out the wire;

[0018] S4. Open the buckle to flip the connecting plate, remove the pay-off reel with the wire paid out, replace it with a pay-off reel wound with the wire, and insert it into the rear tractor again for preparation work.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: For this wire pay-out device for transmission lines, the alternate work of the two rear tractors can be adopted to realize the continuous wire pay-out work of the device. Through the cooperation of components such as gears, the traction speed and direction between the rear tractor and the front tractor are both the same, improving the construction efficiency. Moreover, the inclined angle formed by the flipped connecting plate realizes the function of facilitating the replacement of the pay-off reel;

[0020] By providing an auxiliary structure, two pay-off reels are provided on the frame, and two rear tractors are provided on the platform. When one of the rear tractors cooperates with the front tractor for wire pay-out work, the other rear tractor guides the wire into the preparation stage. When the pay-out of one group ends, the other rear tractor immediately replaces it to continue the pay-out work, thereby realizing the continuity of the wire pay-out of the wire pay-out device for transmission lines, reducing the interruption links of the equipment, avoiding frequent start-stop, and improving the construction efficiency;

[0021] Furthermore, when the rear tractor is moved alternately, through the meshing between gears and the extrusion of the pressing rod on the movable block, when the rear tractor moves to the designated position, it works synchronously with the front tractor to tow the wire, and the towing direction and speed are both the same. There is no need to adjust the synchronism between the tractors, which can avoid the phenomena of wire pulling or slackening during construction;

[0022] By setting a disassembly and assembly structure, the connecting plate is hingedly connected to the frame. The flipping connecting plate forms an inclined angle with the ground. When replacing the unwinding roller, due to the excessive weight of the unwinding roller, it is inconvenient for the staff to carry during replacement. After the connecting plate is flipped, it can play an auxiliary role to a certain extent and can serve as a reliance during handling, thus realizing that the wire laying device for transmission lines is convenient for replacing the unwinding roller, making the staff time-saving and labor-saving and the operation simplified.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 - 12 , a continuous transmission line wire laying device and its wire laying method provided by the present invention include a frame 1 and a platform 4 installed at one end thereof.

The transmission shafts 6 are located at the central position of the unwinding rollers 7. The transmission shafts 6 can limit the wire, avoid excessive traction angle and pulling on the wire, and the transmission shafts 6 can rotate to reduce friction when the wire passes through.

[0038] A lead screw 21 is arranged inside the sliding table 2, and a servo motor 22 is installed on one side of the lead screw 21. Sliding seats 23 are installed at the bottom ends of the rear tractors 5, and the sliding seats 23 are threadedly connected to the lead screw 21.

[0039] Refer to Figure 2 , Figure 3 and Figure 11As shown, when replacing the unwinding roller 7 after the wire unwinding is completed, the connecting plate 81 is flipped to contact the ground to form an inclined angle. By pulling the unwinding roller 7, it can be gradually slid and transported relying on the connecting plate 81, saving effort and reducing the operation difficulty. Then, the unwinding roller 7 that needs to unwind the wire is pushed along the connecting plate 81 to the central position of the frame 1, and then the connecting plate 81 is flipped and merged with the frame 1, and the buckle 82 and the clamping block 83 are clamped and fixed to realize the function of facilitating the replacement of the unwinding roller 7.

[0040] An auxiliary structure 9 is provided between the front tractor 3 and the rear tractor 5; the auxiliary structure 9 includes a bracket 91 installed on the top of the platform 4, and movable shafts 97 are installed on both sides of the bracket 91. At the bottom ends of the movable shafts 97, first transmission gears 94 are installed. At the top ends of the movable shafts 97, second transmission gears 95 are provided. At one end of the second transmission gears 95 at the top, pressing rods 96 are provided at one end of the rear tractor 5. At the bottom of the connecting shafts 32 at one end of the first transmission gears 94, first connecting gears 92 are installed, and the first connecting gears 92 and the first transmission gears 94 are meshed and connected. At the bottom of the rear tractor 5 at one end of the second transmission gears 95, second connecting gears 93 are installed, and the second connecting gears 93 and the second transmission gears 95 are meshed and connected. The second transmission gears 95 and the movable shafts 97 are rotationally connected. Inside the front tractor 3 and the rear tractor 5, transmission gear sets 31 are installed, and connecting shafts 32 are installed on both sides at the bottom of the front tractor 3.

[0041] Refer to Figure 4 、 Figure 5 、 Figure 8 and Figure 9 As shown, when the front tractor 3 is started to work, the two conveyor belts inside it move in opposite directions through the transmission gear set 31 to achieve the function of guiding the wire. The first connecting gear 92 below it and the first transmission gear 94 are meshed. When the front tractor 3 works, the first transmission gear 94 rotates, and the movable shaft 97 fixed to it rotates simultaneously. The second transmission gear 95 and the movable shaft 97 are rotationally connected. When the movable shaft 97 rotates, the second transmission gear 95 remains stationary. When replacing the two rear tractors 5, the second connecting gear 93 below it is displaced to the position of the second transmission gear 95 and gradually meshes with the second transmission gear 95 by continuous movement.

[0042] On both sides of the top of the second transmission gear 95, there are abutting blocks 951 installed, and on one side of each abutting block 951, there is a tension spring 952 connected. On the top of the movable shaft 97, there is a movable block 972 installed, and on the top of the movable block 972, there is a return spring 971 arranged. The top of the movable block 972 is trapezoidal in shape. Inside the movable block 972, there is a slider 974. On the outer wall of the movable shaft 97 of the slider 974, there are sliding grooves 973 arranged, and a sliding structure is formed between the sliding grooves 973 and the slider 974. At the bottom of the movable block 972, there is a ratchet tooth 953, and a latching structure is formed between the ratchet tooth 953 and the abutting block 951.

[0043] Refer to Figure 9 、 Figure 10 and Figure 12 As shown, when the second connecting gear 93 and the second transmission gear 95 are engaged, the rear tractor 5 moves to the designated position, and the pressing rod 96 at one end of it presses the movable block 972. At the bottom end of the pressing rod 96, there are balls. The top of the movable block 972 is trapezoidal in shape. When pressing it, the friction force is reduced, so that the movable block 972 moves downward, and the ratchet tooth 953 and the abutting block 951 are latched. The second transmission gear 95 is driven to rotate by the ratchet tooth 953, so that the second connecting gear 93 engaged with it rotates simultaneously, driving the rear tractor 5 and the front tractor 3 to work simultaneously, making the rhythm of the equipment unified and the wire releasing speed consistent.

[0044] A preparation method of a continuous power transmission line wire releasing device includes the following steps:

[0045] S1. First, turn the connecting plate 81 to contact the ground to form an inclined angle. When placing the unwinding roller 7 inside the frame 1, the inclined angle of the connecting plate 81 can play an auxiliary role to a certain extent. The unwinding roller 7 is pushed along the connecting plate 81 to the central position of the frame 1, and then the connecting plate 81 is turned and merged with the frame 1, and the buckle 82 and the clamping block 83 are latched and fixed;

[0046] S2. Before restarting, the front tractor 3 operates. Inside it, the traction of the wire is achieved through the transmission gear set 31. The first connecting gear 92 below it meshes with the first transmission gear 94. The servo motor 22 is started to drive the lead screw 21 to rotate, and the two rear tractors 5 above it are driven to translate through the slide block 23, so that one of the rear tractors 5 is flush with the front tractor 3. While the rear tractor 5 is moving, the second connecting gear 93 below it is displaced to mesh with the second transmission gear 95. The second transmission gear 95 is rotatably connected to the movable shaft 97. When the movable shaft 97 rotates, the second transmission gear 95 remains stationary. At the same time, the pressing rod 96 at one end of the rear tractor 5 squeezes the movable block 972, causing it to displace downward, so that a latching occurs between the ratchet tooth 953 and the abutting block 951, thereby driving the second transmission gear 95 to rotate, causing the second connecting gear 93 meshing with it to rotate simultaneously, and driving the rear tractor 5 and the front tractor 3 to operate simultaneously;

[0047] S3. Stretch the wire to one end of the rear tractor 5 and pay out the wire outward by the traction force. At the same time, pass the wire on the other pay-off reel 7 through the other rear tractor 5 to make it in a preparatory stage. When the pay-out of this group of wire ends, immediately start the servo motor 22 to drive the lead screw 21 to work, translate this group of rear tractors 5 to one side, and the other group of rear tractors 5 is synchronously translated to a position flush with the front tractor 3. At the same time, the operation of the rear tractor 5 is realized through components such as gears, and the wire is pulled to the front tractor 3 to continuously pay out the wire;

[0048] S4. Open the buckle 82 and flip the connecting plate 81 to remove the pay-off reel 7 that has finished paying out the wire, replace it with a pay-off reel 7 wound with wire, and insert it into the rear tractor 5 again for preparatory work.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
