Description

Technical Field

[0001] The invention relates to the technical field of power cable installation, in particular to a new energy tension machine used for installing and tightening power cables. Background Art

[0002] The power cable tensioner plays a vital role in power engineering and is mainly used in the laying and erecting of power cables. The pay-off device is responsible for storing and releasing cables to ensure a stable supply of cables. The traction device can assist the cables to move forward smoothly during the laying process to avoid problems such as jamming. The use of the power cable tensioner greatly improves the efficiency and quality of power cable laying, and can effectively avoid loosening, sagging or entanglement of cables during the laying process, reducing cable damage and failure rates. At the same time, the power cable tensioner also meets the requirements of modern power engineering for environmental protection, efficiency and safety, and provides a strong guarantee for the smooth progress of power engineering.

[0003] During the erection of high-voltage towers, the cable needs to pass through a tension machine. In the early stage of cable production, the cable is evenly wound on the outside of the winding roller. When the cable on the outside of the winding roller is conveyed to the tension machine, due to the winding characteristics of the cable, that is, it is evenly wound from one end of the winding roller to the other end, and the tension machine and the tension roller are usually fixed on the ground, so that the position of the tension machine receiving the cable is fixed. Because the cable pay-off is reciprocating, the cable tension released from the middle and both ends of the winding roller is different, and the two sides are looser, which increases the jitter of the cable during the pay-off process. At the same time, it is easy for the cable to not fall accurately into the groove of the tension roller, increasing the possibility of the cable being stuck in the gap. In view of the above technical defects, a solution is now proposed. Summary of the invention

[0004] The purpose of the present invention is to provide a new energy tension machine used for power cable installation and tensioning, which is used to solve the problem that due to the reciprocating cable pay-off position and winding characteristics, the cable tension released from the middle and both ends of the winding roller is different, the two sides are looser, and the jitter during the pay-off process is increased, making it difficult for the cable to fall accurately into the tension roller groove.

[0005] To achieve the above object, the present invention provides the following technical solution: a new energy tension machine used for installation and tensioning of power cables, comprising a mounting plate, a tension machine is fixedly mounted on the inner side of the mounting plate, a support plate is fixedly connected to the end side wall of the mounting plate, and a jitter control component for assisting the stable operation of the tension machine is arranged above the support plate; The jitter control component includes a slide plate, the top of which is fixedly connected to pad block 1 and pad block 2, the top of pad block 1 is fixedly connected to frame 1, two truncated cone guide rollers are movably connected to the frame 1 through bearings, the top of pad block 2 is fixedly connected to frame 2, the interior of frame 2 is movably connected to two auxiliary conveying rollers through bearings, the side wall of pad block 2 is fixedly connected to bracket 1, and abutment rollers are movably connected to bracket 1 through bearings.

[0006] Furthermore, two supporting plates are fixedly connected to the bottom of the slide plate, a bearing block is fixedly connected to the bottom end of the supporting plate, a slot is formed through the top of the bearing block, and a sleeve is embedded and fixed in the slot; A push rod is slidably connected in the sleeve, a connecting plate is fixedly connected to the top of the push rod, a shaft sleeve is fixedly connected to the bottom of the push rod, and guide rollers are movably connected to both ends of the shaft sleeve through bearings.

[0007] Furthermore, a push rod is fixedly connected to the top of the connecting plate, a sliding hole is opened through the top of the sliding plate, the push rod is slidably connected in the sliding hole and is fixedly connected to the push plate, the outer side of the push plate is fixedly connected to a connecting frame, the top of the connecting frame is fixedly connected to a bracket two, and an upper push roller is movably connected to the bracket two through a bearing.

[0008] Furthermore, the top and bottom of the inner wall of the second frame are movably connected with auxiliary directional rollers through bearings, the side wall of the support block is penetrated with two sliding grooves and threaded grooves, the top of the support plate is fixed with a frame, the inner side wall of the frame is fixedly connected with two track plates, and the guide rollers cooperate with the track grooves opened on the side walls of the track plates.

[0009] Furthermore, a reciprocating screw and two auxiliary sliding rods are arranged inside the frame, the bearing block cooperates with the reciprocating screw and the auxiliary sliding rod, and a servo motor for driving the reciprocating screw to rotate is arranged on the outside of the frame, and the servo motor is electrically connected to an external power supply.

[0011] Furthermore, a pay-off drum is provided on one side of the tension machine, and a cable is wound on the outer side of the pay-off drum.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention fully takes into account the characteristics that the pay-off position of the pay-off drum is horizontally reciprocating and changes in real time. Through the mutual cooperation between the track groove opened on the side wall of the track plate and the guide roller, the upper push roller can be driven to perform corresponding regular lifting and lowering. The regular lifting and lowering movement of the upper push roller cooperates with the fixed abutment roller to achieve the purpose of real-time adjustment of the height of the upper push roller relative to the abutment roller, thereby realizing real-time adjustment of the cable tension, ensuring that the cable can always remain taut when the pay-off position is constantly switched, further improving the stability and reliability of the cable pay-off process, and effectively reducing various problems caused by cable relaxation or shaking. At the same time, it also makes the cable laying in the process of high-voltage tower erection more efficient and accurate, providing a strong guarantee for the smooth progress of the entire project.

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.

[0016] Embodiment 1: Figure 1-Figure 6 As shown, the new energy tension machine used for installation and tensioning of power cables comprises a mounting plate 1, a tension machine 2 is fixedly mounted on the inner side of the mounting plate 1, and a pay-off drum 18 is arranged on one side of the tension machine 2. In the new energy tension equipment used for installation and tensioning of cables, the pay-off drum 18 serves as a storage and supply device for cables 19, provides a source of cables 19 and controls the pay-off speed; At the same time, the special surface treatment of the pay-off drum 18 can reduce the wear of the cable 19, and its design can also prevent the cable 19 from twisting, which plays an important role in protecting the quality of the cable 19 and provides reliable protection for the installation of the power cable 19. The cable 19 is wound around the outer side of the pay-off drum 18, and the end side wall of the mounting plate 1 is fixedly connected with a support plate 3. A jitter control component 4 for assisting the stable operation of the tension machine 2 is arranged above the support plate 3; The vibration control component 4 includes a slide plate 401, the top of the slide plate 401 is fixedly connected with a cushion block 1 and a cushion block 2, the top of the cushion block 1 is fixedly connected with a frame 1 901, two truncated cone guide rollers 405 are movably connected in the frame 1 901 through bearings, the cable 19 passes between the two truncated cone guide rollers 405, and the truncated cone guide rollers 405 guide and transport the cable 19, the top of the cushion block 2 is fixedly connected with a frame 2 902, the interior of the frame 2 902 is movably connected with two auxiliary conveying rollers 406 through bearings, the side wall of the cushion block 2 is fixedly connected with a bracket 1, and an abutting roller 407 is movably connected in the bracket 1 through bearings; The top and bottom of the inner wall of frame 2 902 are movably connected to auxiliary directional rollers 21 through bearings, the top of the connecting plate 6 is fixedly connected to the push rod 10, and a sliding hole is opened through the top of the slide plate 401. The push rod 10 is slidably connected in the sliding hole and is fixedly connected to the push plate 11. The outer side of the push plate 11 is fixedly connected to a connecting frame 12, and the top of the connecting frame 12 is fixedly connected to a bracket 2, and an upper push roller 408 is movably connected to the inside of the bracket 2 through a bearing.

[0017] In the specific setting, a pay-off drum 18 is arranged on one side of the tension machine 2, and a high-voltage cable erection tower (not shown in the figure) is arranged on the other side of the tension machine 2. The cable 19 in the pay-off drum 18 is stably transported to the top of the high-voltage cable erection tower through the cooperation of the tension machine 2 and the jitter control component 4, so as to realize the long-distance erection and transportation of the cable 19. A plurality of transmission rollers (not shown in the figure) are arranged between the pay-off drum 18 and the jitter control component 4. The transmission roller is an existing structure, which is used for stably transporting the cable 19. After passing through a plurality of transmission rollers, the cable 19 passes through the top of the push-up roller 408, and then passes through the bottom of the abutment roller 407 in turn, and then passes through the pay-off roller in the tension machine 2 and is finally transported to the top of the high-voltage cable erection tower.

[0018] Embodiment 2: In the erection of a high-voltage tower, the cable is evenly wound on the outside of the pay-off drum 18 from the early stage of production, while the tension machine 2 and the tension roller are fixed on the ground, and the receiving cable 19 is fixed. Since the cable 19 pays off reciprocatingly and the cable 19 released at different positions on the pay-off drum 18 has different tensions, the two sides are relatively loose, which increases the pay-off jitter and makes it difficult for the cable 19 to accurately fall into the tension roller groove, increasing the probability of getting stuck in the gap and causing jumpers. In order to solve the above problems, a jitter control component 4 is introduced, and the specific operation process is as follows: Two supporting plates 8 are fixedly connected to the bottom of the slide plate 401, and a bearing block 402 is fixedly connected to the bottom end of the supporting plate 8. A slot is formed through the top of the bearing block 402, and a sleeve 5 is embedded and fixed in the slot. A push rod 403 is slidably connected in the sleeve 5. A connecting plate 6 is fixedly connected to the top of the push rod 403, and a shaft sleeve 7 is fixedly connected to the bottom of the push rod 403. Both ends of the shaft sleeve 7 are movably connected to guide rollers 404 through bearings. Two sliding grooves and threaded grooves are formed through the side wall of the bearing block 402, and a frame 20 is fixed to the top of the support plate 3. Two track plates 13 are fixedly connected to the inner wall of the frame 20, and the guide rollers 404 cooperate with the track grooves formed on the side walls of the track plates 13.

[0019] A reciprocating screw 14 and two auxiliary slide bars 15 are arranged inside the frame 20, the bearing block 402 cooperates with the reciprocating screw 14 and the auxiliary slide bars 15, and a servo motor for driving the reciprocating screw 14 to rotate is arranged on the outside of the frame 20, and the servo motor is electrically connected to an external power supply. The driving device of the present invention is powered by an external power supply, which is cleaner and more environmentally friendly than traditional equipment driven by fuel, and has the advantage of new energy.

[0020] The top of the frame 20 is fixedly connected with a linear track 16 and an I-shaped limit frame 17, and the linear track 16 and the I-shaped limit frame 17 are slidably connected with a linear slider and an I-shaped slider, respectively. The linear slider and the I-shaped slider are fixedly connected to one end and one side of the bottom of the slide plate 401.

[0021] In the specific setting, the servo motor drives the reciprocating screw rod 14 to rotate, and the bearing block 402 slides stably along the auxiliary slide rod 15 under the action of the thread groove and the reciprocating screw rod 14. Figure 4 As shown, the two ends of the track groove opened on the side wall of the track plate 13 are higher than the middle section; When the guide roller 404 rolls from one end of the track groove to the other end, the guide roller 404 first rolls from a higher position of the track groove to the bottom of the middle section, and the guide roller 404 drives the push rod 403 to move downward through the shaft sleeve 7, and the push rod 403 drives the push rod 10 to move downward by driving the connecting plate 6. During the downward movement of the push rod 10, the push plate 11 is driven to move downward synchronously until the push plate 11 drops to the lowest position; At this time, the slide plate 401 moves to the middle of the linear track 16, and the cable 19 is paid out to the middle of the pay-off drum 18. At this time, the cable 19 is closest to the position of the jitter control component 4. The cable 19 passes through the upper push roller 408 and the abutment roller 407 and enters the frame 2 902. Under the action of the symmetrically arranged auxiliary conveying rollers 406 and the auxiliary directional rollers 21, stable conveying is achieved; When the pay-off position of the cable 19 moves from the middle of the pay-off drum 18 to the other end, the movable guide roller 404 moves synchronously from the lowest position of the track groove to the highest position on the other side of the track groove. At this time, the top rod 10 drives the push plate 11 to move upward synchronously, and the push plate 11 drives the upper push roller 408 to move upward through the connecting frame 12. Since the positions passed by the cable 19 in sequence are the top of the upper push roller 408 and the bottom of the abutment roller 407, when the upper push roller 408 moves upward, the upper push roller 408 gradually rises relative to the abutment roller 407, increasing the travel distance of the cable 19, thereby achieving the purpose of increasing the tension of the cable 19 at this time, and effectively eliminating the problem of cable 19 jumping due to insufficient tension caused by the relaxation of the cable 19.
