Description

Technical Field

[0001] This utility model relates to the field of anchoring mechanism technology, specifically to a prestressed steel bar tensioning and anchoring mechanism for cement poles. Background Technology

[0002] The prestressed steel bar tensioning and anchoring mechanism for cement poles is a device used to tension and anchor prestressed steel bars during the manufacturing of cement poles. After the cement pole reaches the predetermined prestress value, the anchoring device is used to fix the steel bars in a tensioned state. After anchoring is completed, the pressure of the tensioning equipment is gradually released to ensure a firm connection between the steel bars and the anchoring device.

[0003] The existing technology has the following problems:

[0004] During the use of the device, the existing device cannot be quickly disassembled and installed. The inability to quickly disassemble and install means that more time is needed when replacing or repairing the equipment. Workers need to spend more physical strength and energy to manually disassemble and install the mechanism, which not only increases labor intensity but may also lead to worker fatigue, thereby affecting work quality and safety. Furthermore, the existing device cannot clamp the limiting plate during use. The main function of the limiting plate is to restrict the position of the reinforcing bar and ensure its stability during tensioning. If the limiting plate cannot be clamped, the reinforcing bar may move or shift during tensioning, resulting in poor fixing effect. If the reinforcing bar moves due to the limiting plate not being clamped, it may lead to equipment failure or safety accidents. Utility Model Content

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0024] like Figure 1-2As shown, this utility model provides a prestressed steel bar tensioning and anchoring mechanism for cement poles, including a fixed base 1, an mounting base 2 movably connected to the front side of the fixed base 1, a fixed column 3 fixedly connected to the front side of the mounting base 2, a limit plate 5 provided on the front side of the fixed column 3, two knobs 7 rotatably connected to the outer wall of the limit plate 5, four snap-fit ​​mechanisms 6 provided on the front side of the mounting base 2, several cement poles 4 movably connected to the rear side of the fixed base 1, multiple through holes 10 opened on the front side of the fixed column 3, multiple anchor clamps 8 movably connected to the inner surface of the through holes 10, grooves 9 opened on the outer wall of the anchor clamps 8, and steel rings 11 movably connected to the inner surface of the grooves 9. The outer wall of the pole 4 is movably connected to the groove 9, and the front side of the anchor clamp 8 is movably connected to the limiting plate 5. In the process of using the existing device, the device can be installed first, and then the cement pole 4 can be passed through the device. After that, the cement pole 4 can be limited and fixed. When limiting and fixing the cement pole 4, the four anchor clamps 8 are first combined together, and the steel ring 11 is clamped in the groove 9. Then, the combined anchor clamps 8 are clamped inside the through hole 10. After the cement pole 4 passes through the anchor clamps 8, it is pressed together with the limiting plate 5, which can squeeze the anchor clamps 8 inward and press the cement pole 4. After pressing, the limiting plate 5 can be clamped.

[0025] like Figure 3-4 As shown, this utility model provides a technical solution: Preferably, a threaded rod 14 is fixedly connected to the side of the knob 7 near the cement pole 4, and a bevel gear 12 is fixedly connected to the end of the threaded rod 14 away from the knob 7. A bevel gear ring 13 is meshed with the outer wall of the bevel gear 12. A lifting plate 16 is threadedly connected to the outer wall of the threaded rod 14. Two limiting rods 15 are fixedly connected to the inner wall of the limiting plate 5. A locking block 17 is fixedly connected to the side of the lifting plate 16 away from the knob 7. Insert blocks 18 are fixedly connected to both the upper and lower ends of the front side of the fixing column 3. The outer wall of the locking block 17 is movably connected to the insert block 18. The outer wall of the limiting rod 15 is slidably connected to the lifting plate 16. The outer wall of the threaded rod 14 is rotatably connected to the limiting plate 5. During the process of clamping the limiting plate 5, the insert block 18 on the front side of the fixing column 3 will first insert into the limiting plate 5. Inside the hole, the knobs 7 at both ends can be rotated. Rotating the knobs 7 will drive the threaded rod 14 to rotate, which in turn will drive the bevel gear 12 to rotate. The bevel gear 12 will then drive the bevel ring 13 to rotate, and the bevel ring 13 will simultaneously drive the lower bevel gear 12 to rotate. As the threaded rod 14 rotates, it will cause the lifting plate 16 to rise and fall on the limiting rod 15. When the two lifting plates 16 move towards the middle, they will drive the locking block 17 to move. Once the locking block 17 is engaged inside the insert block 18, the insert block 18 can be fixed in place. The locking function of the limiting plate 5 ensures that the position of the cement pole 4 can be stably controlled during the tensioning process, reducing the need for repeated adjustments and corrections caused by the movement or offset of the cement pole 4.

[0026] like Figure 5 As shown, this utility model provides a technical solution: Preferably, the snap-fit ​​mechanism 6 includes a movable plate 64, a snap-fit ​​block 63 fixedly connected to the rear end of the movable plate 64, a limit post 65 fixedly connected to the inner wall of the mounting base 2, a spring 66 sleeved on the outer wall of the limit post 65, a snap-fit ​​plate 62 rotatably connected to the front end of the movable plate 64, a snap buckle 61 fixedly connected to the front side of the mounting base 1, the outer wall of the snap buckle 61 movably connected to the snap-fit ​​plate 62, the outer wall of the limit post 65 slidably connected to the snap-fit ​​block 63, the outer wall of the snap-fit ​​block 63 movably connected to the mounting base 1, one end of the spring 66 fixedly connected to the mounting base 2, and the other end of the spring 66... The device is fixedly connected to the snap-fit ​​block 63. During the installation process, the mounting base 2 can be snapped into the interior of the fixed base 1 first. Then, the moving plate 64 can be pulled. The movement of the moving plate 64 will drive the snap-fit ​​block 63 to move. The snap-fit ​​block 63 can be inserted into the interior of the fixed base 1. Then, the snap-fit ​​plate 62 is rotated to snap into the buckle 61. Then, the moving plate 64 is released. At this time, the spring 66 will pull the snap-fit ​​block 63 to snap the snap-fit ​​plate 62 and the buckle 61 more tightly, thereby limiting and fixing the device. The quick disassembly and installation function makes the entire tensioning and anchoring process more efficient, saves time, and speeds up the overall construction speed.

[0027] The working principle of the prestressed steel bar tensioning and anchoring mechanism for cement poles will be explained in detail below.

[0028] like Figure 1-5As shown, in the existing device, during use, the device can be installed first. During installation, the mounting base 2 can be inserted into the fixed base 1. Then, the movable plate 64 can be pulled. The movement of the movable plate 64 will cause the locking block 63 to move, allowing the locking block 63 to insert into the fixed base 1. Then, the locking plate 62 can be rotated to engage with the buckle 61. Next, the movable plate 64 can be released. At this time, the spring 66 will pull the locking block 63, making the locking plate 62 and the buckle 61 more tightly engaged, thereby ensuring the device's stability. The device features a limit and fixation mechanism, and its quick disassembly and installation functions make the entire tensioning and anchoring process more efficient, saving time and accelerating the overall construction speed. The cement pole 4 is then passed through the device, and subsequently, it is limited and fixed. To limit and fix the cement pole 4, the four anchor clamps 8 are first assembled together, and the steel ring 11 is secured in the groove 9. Then, the assembled anchor clamps 8 are secured inside the through hole 10. After the cement pole 4 passes through the anchor clamps 8, the limiting plate 5 is engaged. Tightening causes the anchor clamp 8 to press inward, compressing the cement pole 4. After tightening, the limiting plate 5 is clamped. During the clamping process of the limiting plate 5, the insert 18 on the front side of the fixing column 3 will first insert into the interior of the limiting plate 5. Then, the knobs 7 at both ends can be rotated. Rotating the knobs 7 will drive the threaded rod 14 to rotate, which in turn will drive the bevel gear 12 to rotate. The rotation of the bevel gear 12 will drive the bevel gear ring 13 to rotate, which in turn will simultaneously drive... The lower bevel gear 12 rotates, and while the threaded rod 14 rotates, it can drive the lifting plate 16 to rise and fall on the limiting rod 15. When the two lifting plates 16 move towards the middle, they will drive the locking block 17 to move. Once the locking block 17 is locked into the interior of the insert block 18, the insert block 18 can be limited and fixed. The locking function of the limiting plate 5 enables the position of the cement pole 4 to be stably controlled during the tensioning process, reducing the repeated adjustment and correction work caused by the movement or displacement of the cement pole 4.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
