Description
Technical Field
[0001] The invention relates to the technical field of a stringing pulley for a collector line engineering construction, in particular to a stringing pulley with adjustable tension for a collector line engineering construction. Background Art
[0002] During the construction of collector lines, the primary function of a stringing pulley is to carry and guide the cables, using the pulley system to pull, release, tension, and position the conductors. The stringing pulley typically consists of a body and guide wheels, suspended from the line conductors. The cables are then transported over the pulley's guide wheels. During construction, the pulley must ensure smooth cable movement while preventing them from slipping. Therefore, when laying long distances, limiters are installed on the guide wheels.
[0003] There are some defects in the cable pulling pulleys currently on the market: since long-distance cables need to be connected through hard connectors, the friction between the hard connectors and the guide wheels is large when passing through, which affects the tension of the cable, easily causing the pulley to jam and the tension to be unstable. The pulley's running speed must be manually observed and adjusted, and direct collision between the limit assembly and the connector can easily cause wear. If no limit assembly is set, the cable may slip off during the passage of the pulley.
[0004] Therefore, a kind of collector line engineering construction stringing pulley with adjustable tension is needed to solve the above-mentioned technical defects. Summary of the Invention
[0005] The object of the present invention is to provide a tension-adjustable stringing pulley for collector line engineering construction, so as to solve the problem in the above-mentioned background technology that when the connector passes through the guide wheel, the change in cable tension causes obstruction of passage.
[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a line-laying pulley for construction of a collector line project with adjustable tensioning, comprising an upper lifting ring and a car body, wherein the upper lifting ring and the bottom ends of the car body are respectively welded with an upper lifting ring and a side lifting ring, a group of guide wheels are movably assembled on both sides of the front end of the car body, a cylinder seat is welded with a cylinder seat in the middle position of the front end of the car body, the top of the cylinder seat is grooved and a lifting frame is movably sleeved, a tensioning wheel is movably assembled in the lifting frame, racks are respectively machined at both ends of the lifting frame, and gear racks are respectively fixedly connected at both ends of the cylinder seat, and a first gear and a second gear are respectively movably connected to the top of the gear rack, the first gear is respectively meshed with the rack and the second gear, a rotating rack is fixedly sleeved at the axis of the second gear, and a limiting plate is fixedly connected to the top of the rotating rack.
[0007] Preferably, the rotating rack is provided with two groups, which are arranged at both ends of the lifting frame, and the limiting plates abut against each other when combined.
[0008] Preferably, two ends of the outer wall of the lifting frame are welded with slots, and the size of the slots matches that of the rotating frame.
[0009] Preferably, the bottom end of the cylinder seat is fixedly connected to a base, a center rod is welded inside the base, the bottom end of the lifting frame is fixedly connected to a piston cylinder, the piston cylinder is sleeved on the outside of the center rod, a spring is abutted between the piston cylinder and the base, and the spring is sleeved on the outside of the center rod.
[0010] Preferably, a wall groove is formed on the inner wall of the base, and a convex block is processed on the bottom edge of the piston cylinder, and the convex block and the wall groove can be slidably engaged.
[0011] Preferably, the first gear and the second gear have the same size, and the first gear is not connected to the rotating frame.
[0012] Preferably, a guide frame fixed to the vehicle body is sleeved at the axis of the guide wheel, an upper brush roller that fits the guide wheel is installed at the top end of the inner wall of the guide frame, and a lower brush roller that fits the tensioning wheel is installed at the middle position of the top end of the cylinder seat.
[0013] Preferably, the guide wheel and the tensioning wheel have the same size.
[0014] Preferably, the two sets of guide wheels and the set of tensioning wheels are located in the same vertical plane, forming an isosceles triangle structure.
[0015] Compared with the prior art, the beneficial effects of the present invention are: the tension-adjustable collector line engineering construction stringing pulley not only realizes self-adjustment of tension and high routing stability, but also realizes a self-cleaning function; (1) The cable pulley is provided with a tensioning wheel, a limit plate, a rack, a first gear, a second gear, and a lifting frame. The cable pulley is suspended on the conductor through an upper lifting ring. The cable is introduced from the bottom end of the guide wheel on the right side of the vehicle body to the top end of the tensioning wheel, and then led out from the bottom end of the guide wheel. When the cable is pulled, the pressure on the tensioning wheel is small. The two sets of limit plates above the tensioning wheel are closed to limit the cable and prevent it from slipping. When the cable connector passes to the top position of the tensioning wheel, the connector squeezes the tensioning wheel due to its own pressure. At this time, the friction force exerted by the connector on the tensioning wheel and the change in transmission tension make the tensioning wheel and the lifting frame together. The spring is compressed by pressing down into the cylinder seat. When the lifting frame descends, the rack and the first gear engage, causing the first gear to rotate and the second gear to rotate in the other direction. The rotating frame drives the limit plates to open outward from both ends of the lifting frame, allowing the cable connector to pass unimpeded. When the connector has completely passed, the spring's rebound force drives the lifting frame up, driving the limit plates to close again, restoring the stable limit of the cable. The self-adjusting tension design ensures that the vehicle body will not be jammed or damaged by friction due to tension changes. The limit components will not interfere with or hinder the connector, greatly improving the continuity and efficiency of construction. (2) By providing a protrusion, a base, a wall groove, a spring, and a card slot, the two sets of limit plates abut against each other when the cable passes through. The gap between the limit plate and the tensioning wheel forms a space for the cable to pass through, preventing the risk of the cable slipping due to steering or uneven force. When the lifting frame is slightly moved up and down in the cylinder seat, the protrusion at the bottom end of the piston cylinder can be embedded in the wall groove on the inner wall of the base to control the compression and rebound process of the spring and ensure stable movement. When the rotating frame is opened and closed, the card slot provides a stable guide. Even if external conditions such as wind changes cause the cable position to shift, the entire vehicle body can still provide effective support. The structure is sophisticated, the loss is low, it is not easy to deform, and the wiring stability is high. (3) By arranging an upper brush roller and a lower brush roller, an upper brush roller and a lower brush roller are respectively arranged at the top of the guide wheel and the bottom of the tension wheel. When the cable moves, the lower brush roller and the upper brush roller are made of flexible material. As the guide wheel and the tension wheel rotate, the brush surface can effectively scrape the rust, dust and particulate impurities attached to the surface of the cable, avoiding damage to the surface of the steel cable and the pulley. It has a self-cleaning function, reduces the risk of mechanical failure caused by impurity accumulation, and does not require manual cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.
[0019] See also Figure 1-6 , an embodiment of the present invention provides: a line pulley with adjustable tension for construction of a collector line project, comprising an upper lifting ring 1 and a car body 2, the upper lifting ring 1 and the side lifting ring 6 being welded to the top and the bottom of the two sides of the car body 2 respectively, a group of guide wheels 3 are movably assembled on both sides of the front end of the car body 2, a cylinder seat 15 is welded to the middle position of the front end of the car body 2, the top of the cylinder seat 15 is slotted and movably sleeved with a lifting frame 9, a tensioning wheel 5 is movably assembled in the lifting frame 9, two ends of the lifting frame 9 are respectively processed with racks 10, two ends of the cylinder seat 15 are respectively fixedly connected to a gear frame 14, the top of the gear frame 14 is respectively movably connected to a first gear 11 and a second gear 12, the first gear 11 is meshed with the rack 10 and the second gear 12 respectively, the second gear 12 is fixedly sleeved with a rotating frame 8 at the axis center, the top of the rotating frame 8 is fixedly connected to a limit plate 7, the rotating frame 8 is provided with two groups, which are arranged at both ends of the lifting frame 9, and the limit plates 7 abut each other when merged, the first gear 11 and the second gear 12 are of the same size, and the first gear 11 is not connected to the rotating frame 8; Specifically, if Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, when the cable is pulled, the pressure on the tensioning wheel 5 is small, and the two sets of limit plates 7 above the tensioning wheel 5 are closed to limit the cable and prevent the cable from slipping. When the cable connector passes through the top position of the tensioning wheel 5, the connector squeezes the tensioning wheel 5 due to its own pressure. At this time, the friction force exerted by the connector on the tensioning wheel 5 and the change in transmission tension cause the tensioning wheel 5 to be pressed down into the cylinder seat 15 together with the lifting frame 9, and the spring 18 is squeezed. When the lifting frame 9 descends, the rack 10 and the first gear 11 are engaged, causing the first gear 11 to rotate, and the second gear 12 to rotate in the other direction, driving the limit plates 7 to open outward from both ends of the lifting frame 9, so that the cable connector can pass through unimpeded. When the connector has completely passed, the rebound force of the spring 18 drives the lifting frame 9 to rise, driving the limit plates 7 to close again, and restoring the stable limit to the cable.
[0020] Slots 13 are welded to both ends of the outer wall of the lifting frame 9. The size of the slots 13 matches that of the rotating frame 8. The bottom end of the cylinder seat 15 is fixedly connected to the base 20. A center rod 19 is welded to the inside of the base 20. The bottom end of the lifting frame 9 is fixedly connected to the piston cylinder 16. The piston cylinder 16 is sleeved on the outside of the center rod 19. A spring 18 is abutted between the piston cylinder 16 and the base 20. The spring 18 is sleeved on the outside of the center rod 19. A wall groove 21 is opened on the inner wall of the base 20. A protrusion 17 is processed on the bottom edge of the piston cylinder 16. The protrusion 17 and the wall groove 21 can be fitted and slidably engaged. Specifically, if Figure 1 、 Figure 2 and Figure 3 As shown, the two sets of limit plates 7 abut against each other when the cable passes through, and the gap between the limit plates 7 and the tensioning wheel 5 forms a space for the cable to pass through, preventing the risk of the cable slipping due to steering or uneven force. When the lifting frame 9 is slightly lifted and lowered in the cylinder seat 15, the protrusion 17 at the bottom end of the piston cylinder 16 can be embedded in the wall groove 21 on the inner wall of the base 20 and slide up and down, controlling the compression and rebound process of the spring 18 to ensure stable movement. When the rotating frame 8 is opened and closed, the card slot 13 provides stable guidance. Even if external conditions such as wind changes cause the cable position to shift, the entire vehicle body 2 can still provide effective support.
[0021] The guide wheel 3 is sleeved with a guide frame 4 fixed to the vehicle body 2 at the axis thereof. An upper brush roller 23 is mounted on the top of the inner wall of the guide frame 4 and is in contact with the guide wheel 3. A lower brush roller 22 is mounted in contact with the tensioning wheel 5 at the middle position of the top of the cylinder seat 15. The guide wheel 3 and the tensioning wheel 5 are of the same size. The two groups of guide wheels 3 and the group of tensioning wheels 5 are in the same vertical plane, forming an isosceles triangle structure. Specifically, if Figure 1 、 Figure 3 and Figure 6 As shown, the lower brush roller 22 and the upper brush roller 23 are made of flexible material. When the cable moves, along with the rotation of the guide wheel 3 and the tensioning wheel 5, the brush surface can effectively scrape off the rust, dust and particulate impurities attached to the cable surface.
[0022] When the cable is pulled, the pressure on the tension wheel 5 is small, and the two sets of limit plates 7 above the tension wheel 5 are closed to limit the cable and prevent it from slipping. When the cable connector passes to the top position of the tension wheel 5, the connector squeezes the tension wheel 5 due to its own pressure. At this time, the friction force exerted by the connector on the tension wheel 5 and the change of transmission tension make the tension wheel 5 and the lifting frame 9 press down into the cylinder seat 15 together. The spring 18 is squeezed. When the lifting frame 9 descends, Due to the meshing of the rack 10 and the first gear 11, the first gear 11 rotates, and the second gear 12 rotates in the other direction, driving the limit plates 7 to open outward from both ends of the lifting frame 9, so that the cable connector can pass through unimpeded. When the connector has completely passed, the rebound force of the spring 18 drives the lifting frame 9 to rise, driving the limit plates 7 to close again, and restoring the stable limit of the cable. When the lifting frame 9 is lifted and lowered slightly in the cylinder seat 15, the protrusion 17 at the bottom end of the piston cylinder 16 can be embedded in the wall groove 21 on the inner wall of the base 20 and slide up and down, controlling the compression and rebound process of the spring 18 to ensure stable movement. An upper brush roller 23 and a lower brush roller 22 are respectively provided at the top of the guide wheel 3 and the bottom of the tensioning wheel 5. When the cable moves, along with the rotation of the guide wheel 3 and the tensioning wheel 5, the brush surface can effectively scrape rust, dust and particulate impurities attached to the cable surface.
