[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0017] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a stable and intelligent engineering line positioning device, including a limiting box 4. A first clamping plate 5 is rotatably connected to the outer wall of the limiting box 4. A first rotating shaft 6 and a first connecting shaft 7 are fixedly connected through the interior of the first clamping plate 5. A second connecting rod 16 is rotatably connected to the outer wall of the first rotating shaft 6. A second rotating shaft 12 is rotatably connected through the interior of the second connecting rod 16. A trapezoidal block 17 is rotatably connected to the outer wall of the first connecting shaft 7. A second connecting shaft 10 and a third connecting shaft 11 are rotatably connected through the interior of the trapezoidal block 17. A second clamping plate 9 is fixedly connected through the outer wall of the second connecting shaft 10. A first connecting rod 13 is fixedly connected through the outer walls of both the third connecting shaft 11 and the second rotating shaft 12. A third rotating shaft 24 is rotatably connected through the interior of the first connecting rod 13. A handle 14 is fixedly connected to the outer wall of the third rotating shaft 24. A second pulley 15 is connected to the outer wall of the first connecting rod 13. A first pulley 8 is rotatably connected to the interior of both the first clamping plate 5 and the second clamping plate 9. A support assembly is provided on the outer wall of the limiting box 4. Specifically, pulling handle 14 causes the third rotating shaft 24 to rotate, which in turn moves the first connecting rod 13. The first connecting rod 13 then rotates the second rotating shaft 12 and the third connecting shaft 11. The third connecting shaft 11 causes the trapezoidal block 17 to slide along the outer walls of the first connecting shaft 7 and the second connecting shaft 10. By setting two trapezoidal blocks 17, the second clamping plate 9 is clamped and limited, but this clamping force does not affect the movement of the second clamping plate 9, thus preventing it from falling off. The second rotating shaft 12 then causes the second connecting rod 16 to rotate along the outer wall of the first rotating shaft 6, which in turn moves the second clamping plate 9 via the second connecting shaft 10. Turning handle 14 will... A linkage mechanism ultimately translates into the linear movement of the second clamping plate 9, thereby achieving the clamping and pulling of the cable. During the pulling of the handle 14, the cable is also pulled to slide against the outer walls of the first pulley 8, the second pulley 15, and the third pulley 23. The first clamping plate 5 is fixed on the turntable 3 and serves as a fixed reference point, forming a clamping opening with the second clamping plate 9. The second clamping plate 9 is movable and serves as a movable clamping claw, moving closer to or away from the first clamping plate 5 under the drive of the linkage mechanism, thereby performing the action of clamping and releasing the cable. The first pulley 8 serves to guide and position the cable, achieving the effect of placing the cable in the correct position, and also plays a rolling clamping role, achieving the effect of reducing cable wear. Through the action of the first pulley 8, the device can smoothly pull the cable while clamping it.
[0018] Reference Figure 2 The support assembly includes an A-frame 1, a support plate 2 fixedly connected to the top of the A-frame 1, a third pulley 23 fixedly connected to the upper surface of the support plate 2, and the outer wall of the limiting box 4 fixedly connected to the upper surface of the support plate 2. Specifically, the A-frame 1 serves to support and fix the support plate 2, and the support plate 2 serves to support and fix the limit box 4 and the third pulley 23, thus achieving a more stable effect for the device during operation.
[0019] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5A turntable 3 is rotatably connected to the upper surface of the support plate 2, and a limiting cylinder 18 is fixedly connected inside the turntable 3. A spring 20 is provided on the inner wall of the limiting cylinder 18, and a round-headed block 19 is slidably connected to the inner wall of the limiting cylinder 18. One end of the spring 20 is fixedly connected to the inner wall of the limiting cylinder 18, and the other end of the spring 20 is fixedly connected to the outer wall of the round-headed block 19. The outer wall of the round-headed block 19 is slidably connected to the inside of the support plate 2, and the upper surface of the turntable 3 is rotatably connected to the inner wall of the limiting box 4. The upper surface of the turntable 3 is fixedly connected to the outer wall of the first clamping plate 5, and an annular groove 21 and a groove 22 are provided inside the support plate 2. Specifically, rotating the first clamping plate 5 causes the turntable 3 to rotate within the inner wall of the limiting box 4 and the support plate 2. The turntable 3 then rotates the limiting cylinder 18, which in turn causes the round-headed block 19 to slide within the annular groove 21. Multiple grooves 22 are machined on the inner wall of the annular groove 21, and these grooves 22 are evenly distributed on the annular groove 21. Each groove 22 represents a fixed cable length position. When the round-headed block 19 falls into any of the grooves 22, the... The device is locked, thus enabling the cable to be pulled out to different fixed lengths. When the limiting cylinder 18 causes the round head block 19 to slide away from the inner wall of the groove 22, it will compress the spring 20. When the round head block 19 is aligned with the groove 22, the reaction force of the spring 20 will cause the round head block 19 to stick tightly to the inner wall of the groove 22, achieving the locking effect. The function of the limiting box 4 is to prevent the turntable 3 from disengaging from the annular groove 21 when the handle 14 is pulled, ensuring the stability of the movement. The function of the limiting cylinder 18 is to limit the round head block 19 and the spring 20, improving the stability during the movement.
[0020] Reference Figure 4 The outer wall of the round-headed block 19 is slidably connected to the inner wall of the annular groove 21 and the groove 22; Specifically, the annular groove 21 serves to limit and guide the round head block 19, ensuring that the movement trajectory of the round head block 19 is a fixed circular motion.
[0021] Working principle: When the device is needed, first pass the cable through the first clamping plate 5 and the second clamping plate 9. Then, use the second pulley 15 to pass the cable from bottom to top into the handle 14. Next, pass the cable through the third pulley 23 and pull the handle 14. The handle 14 will drive the third rotating shaft 24 to rotate, which in turn drives the first connecting rod 13 to move. The first connecting rod 13 will then drive the second rotating shaft 12 and the third connecting shaft 11 to rotate. The third connecting shaft 11 will then drive the trapezoidal block 17 to rotate on the first connecting shaft 7 and the second connecting shaft 10. The cable slides along the outer wall of the first rotating shaft 6, thereby driving the second connecting rod 16 to rotate along the outer wall of the first rotating shaft 6 via the second rotating shaft 12. This, in turn, drives the second clamping plate 9 to move via the second connecting shaft 10, thereby clamping the cable via the first pulley 8. When the handle 14 is pulled, the cable also slides along the outer walls of the first pulley 8, the second pulley 15, and the third pulley 23. Therefore, pulling the handle 14 can not only clamp the cable but also pull it, thus achieving the effect of clamping cables of different thicknesses and improving the applicability of the device. Then, the first clamping plate 5 can be rotated, which in turn drives the turntable 3 to rotate on the inner wall of the limiting box 4 and the support plate 2. The turntable 3 then drives the limiting cylinder 18 to rotate, which in turn drives the round-headed block 19 to slide inside the annular groove 21. When the round-headed block 19 slides away from the inside of the groove 22, it will compress the spring 20. When the round-headed block 19 slides back into the inside of the groove 22, the reaction force of the spring 20 will cause the round-headed block 19 to contact the inner wall of the groove 22, thus limiting the round-headed block 19 inside the groove 22. This allows cables of different lengths to be pulled out, achieving a more convenient cable testing effect.
