Description

Technical Field

[0001] This utility model relates to the field of concrete-related technology, specifically to a tensioning and anchoring device for prestressed concrete poles. Background Technology

[0002] Concrete, often simply called PT, is a general term for engineering composite materials made by binding aggregates together with cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement, sand, and gravel as aggregates with water and potentially admixtures in a specific ratio. It is widely used in civil engineering and is one of the most important civil engineering materials today. Workers need to insert utility poles vertically into the concrete while it is still uncured.

[0003] Utility model patent CN219711014U discloses a tensioning and anchoring device for prestressed concrete poles, belonging to the field of concrete-related technology. It addresses the problem in existing technologies where the lack of a limiting mechanism for the pole body leads to potential movement and misalignment when the pole is placed vertically into concrete. The device includes a main structure and an auxiliary structure. The top surface of the auxiliary structure is fixedly connected to the bottom surface of the main structure, and the auxiliary structure is located at the bottom of the main structure. The main structure includes a support member and the pole body. The first limiting member in this utility model effectively limits the top of the pole body, preventing misalignment during subsequent placement into the concrete. The position of the first limiting member is adjustable. When the first electric telescopic rod retracts or extends, it simultaneously moves a slider within a groove. As the slider moves, the support and the first limiting member are also moved. The user can adjust the position of the first limiting member according to the specifications of the pole body.

[0004] However, the above patent still has shortcomings: although the patent can limit the position of the pole, the curvature of the internal limiting component is not adjustable, and there are many types of poles. When the limiting component limits poles of different diameters, the contact area between the limiting component and the pole is small and the fit is poor, resulting in the pole being clamped unstable and prone to shaking. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a prestressed concrete pole tensioning and anchoring device to solve the problem mentioned in the background art. Although the existing prestressed concrete pole tensioning and anchoring devices can limit the position of the pole, the curvature of the internal limiting member is not adjustable. In addition, there are many types of poles, which means that when limiting poles of different diameters, the contact area between the limiting member and the pole is small and the fit is poor, resulting in unstable clamping of the pole and easy shaking.

[0006] The technical solution of this utility model is:

[0007] A prestressed concrete pole tensioning and anchoring device includes: a platform; an adjustment frame is provided at the top center of the platform, a fixed box is provided inside the adjustment frame, a pole body is provided at the center of the fixed box, four fixing claws are provided at both ends of the fixed box, and a moving block is fixedly connected to each fixing claw near the fixed box, and the moving block is slidably connected to the fixed box; a linkage mechanism for locking and fixing pole bodies of different diameters is provided inside the fixed box; and a rotation mechanism for multi-angle adjustment of the pole body is provided inside the adjustment frame.

[0008] Preferably, the linkage mechanism includes: a brake motor fixedly connected inside the fixed box; a first rotating shaft fixedly connected to the output end of the brake motor; a first bevel gear fixedly connected to the end of the first rotating shaft away from the brake motor; and second bevel gears meshing on both sides of the first bevel gear; a rotating sleeve fixedly connected inside each of the second bevel gears; a flat screw plate fixedly connected to the end of each rotating sleeve away from the second bevel gear; the flat screw plate and the rotating sleeve are rotatably connected to the fixed box; and the moving block meshes with the flat screw plate respectively.

[0009] Preferably, the movable block has sliding grooves on both sides, and the fixed box is fixedly connected with limit strips near the sliding grooves.

[0010] Preferably, the rotating mechanism includes: two second rotating shafts rotatably connected inside the adjusting frame, the ends of the second rotating shafts away from the adjusting frame being fixedly connected to the fixed box; a slot is provided in the adjusting frame near one of the second rotating shafts; a first worm gear is provided inside the slot, the first worm gear is fixed to the outer surface of the second rotating shaft, a first worm is engaged at the top of the first worm gear, one end of the first worm is rotatably connected to a first fixing block, the other end of the first worm passes through the first fixing block and extends to a first knob, the first knob is fixedly connected to the first worm, and the first fixing blocks are all fixedly connected to the adjusting frame; an auxiliary mechanism for adjusting the adjusting frame is provided on one side of the adjusting frame perpendicular to the second rotating shaft.

[0011] Preferably, the auxiliary mechanism includes: a third rotating shaft fixedly connected to one side of the adjustment frame perpendicular to the second rotating shaft; a second fixing block rotatably connected to one end of each third rotating shaft; and the second fixing block being fixedly connected to the table surface. A second worm gear is fixedly connected to the end of one of the third rotating shafts away from the second fixing block; a second worm engages with the bottom of the second worm gear; a third fixing block rotatably connects to one end of the second worm; the other end of the second worm passes through the third fixing block and extends to a second knob; the second knob is fixedly connected to the second worm; and the third fixing block is fixedly connected to the table surface.

[0012] Preferably, each of the fixing claws is provided with a damping pad on the side near the pole body, and the damping pads are fixedly connected to the fixing claws respectively.

[0013] Preferably, support rods are fixedly connected to the four bottom corners of the tabletop, support blocks are fixedly connected to the bottom of each support rod, and anti-slip pads are fixedly connected to the bottom of each support block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Firstly, this utility model, through the coordinated action of the platform, adjusting frame, fixing box, pole body, fixing claw, moving block, and linkage mechanism, can stably clamp and limit poles of different diameters, preventing the poles from swaying. This solves the problem that while existing prestressed concrete pole tensioning and anchoring devices can limit the poles, the curvature of their internal limiting components is not adjustable, and the wide variety of pole models results in a small contact area and poor fit between the limiting components and the poles when limiting poles of different diameters, leading to unstable clamping and easy swaying of the poles.

[0016] Secondly, through the combined action of the platform, adjusting frame, fixing box, pole body, fixing claw, moving block and rotating mechanism, this utility model can be used on ground with poor levelness to adjust the fixing box at multiple angles to ensure that the fixing box is in a horizontal state, thereby ensuring that the pole is in a vertical state, thus improving its practicality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 The present invention will describe the above technical solution in detail through the following embodiments:

[0027] A prestressed concrete pole tensioning and anchoring device includes: a platform 1; an adjustment frame 2 is provided at the top center of the platform 1, a fixed box 3 is provided inside the adjustment frame 2, a pole body 4 is provided at the center of the fixed box 3, four fixing claws 5 are provided at both ends of the fixed box 3, and a moving block 6 is fixedly connected to each fixing claw 5 near the fixed box 3, and the moving block 6 is slidably connected to the fixed box 3; a linkage mechanism 7 is provided inside the fixed box 3 for locking and fixing pole bodies 4 of different diameters; a rotation mechanism 8 is provided inside the adjustment frame 2 for multi-angle adjustment of the pole body 4. The user places the pole body 4 at the center of the fixed box 3, and then controls the moving block 6 to slide towards the pole body 4 simultaneously through the linkage mechanism 7. As the moving block 6 slides, it drives the fixing claws 5, so that the eight fixing claws 5 cooperate to fix and limit the pole body 4. Then, the fixed box 3 is adjusted by the rotation mechanism 8 and the adjustment frame 2 to keep the fixed box 3 horizontal, so that the pole body 4 is in a vertical state.

[0028] like Figure 4 As shown, the linkage mechanism 7 includes: a brake motor 9 fixedly connected inside the fixed housing 3; a first rotating shaft 10 fixedly connected to the output end of the brake motor 9; a first bevel gear 11 fixedly connected to the end of the first rotating shaft 10 away from the brake motor 9; and second bevel gears 12 meshing on both sides of the first bevel gear 11; a rotating sleeve 13 fixedly connected inside each of the second bevel gears 12; and a flat screw disc 33 fixedly connected to the end of the rotating sleeve 13 away from the second bevel gear 12; both the flat screw disc 33 and the rotating sleeve 13 are rotatably connected to the fixed housing 3; and the moving block 6 meshes with the flat screw disc 33 respectively. The brake motor 9 is started, and the output end of the brake motor 9 drives the first rotating shaft 10. The first rotating shaft 10 rotates and drives the first bevel gear 11. The first bevel gear 11 drives the two second bevel gears 12. The second bevel gears 12 drive the rotating sleeve 13 respectively. The rotating sleeve 13 rotates and drives the flat screw disc 33. The flat screw disc 33 pushes the moving block 6 through the flat thread on its surface. The moving block 6 slides towards the pole body 4 through the cooperation of the fixed box 3. While the moving block 6 slides, it drives the fixed claws 5. Then, the eight fixed claws 5 cooperate to clamp and fix the pole body 4.

[0029] like Figure 3 As shown, sliding grooves 14 are provided on both sides of the movable block 6, and limiting slide bars 15 are fixedly connected to the fixed box 3 near the sliding grooves 14, which can limit the movable block 6 and make the movable block 6 slide flexibly inside the fixed box 3.

[0030] like Figure 5 and Figure 6As shown, the rotating mechanism 8 includes: two second rotating shafts 16 rotatably connected inside the adjusting frame 2, with the ends of the second rotating shafts 16 away from the adjusting frame 2 fixedly connected to the fixed box 3; a slot 17 is provided in the adjusting frame 2 near one of the second rotating shafts 16; a first worm gear 18 is provided inside the slot 17, the first worm gear 18 is fixed to the outer surface of the second rotating shaft 16, a first worm 19 is engaged at the top of the first worm gear 18, one end of the first worm 19 is rotatably connected to a first fixing block 20, and the other end of the first worm 19 passes through the first fixing block 20 and extends to the first knob 2. At point 1, the first knob 21 is fixedly connected to the first worm gear 19, and the first fixing block 20 is fixedly connected to the adjustment frame 2. An auxiliary mechanism 22 for adjusting the adjustment frame 2 is provided on one side of the adjustment frame 2 perpendicular to the second rotating shaft 16. When the user rotates the first knob 21, the first knob 21 drives the first worm gear 19. The first worm gear 19 rotates with the cooperation of the first fixing block 20. At the same time, the rotation of the first worm gear 19 drives the first worm wheel 18. The first worm wheel 18 drives the second rotating shaft 16. The second rotating shaft 16 drives the fixing box 3, thereby adjusting the front and rear angle of the fixing box 3.

[0031] like Figure 5 As shown, the auxiliary mechanism 22 includes: a third rotating shaft 23 fixedly connected to one side of the adjusting frame 2 perpendicular to the second rotating shaft 16; a second fixing block 24 rotatably connected to one end of each third rotating shaft 23; and the second fixing blocks 24 fixedly connected to the table surface 1. A second worm gear 25 is fixedly connected to the end of one of the third rotating shafts 23 away from the second fixing block 24. A second worm 26 is meshed with the bottom of the second worm gear 25. A third fixing block 27 rotatably connects to one end of the second worm 26, and the other end of the second worm 26 passes through the third fixing block 27 and extends to the second knob 28. The second knob 28 is fixedly connected to the second worm gear 26, and the third fixing block 27 is fixedly connected to the table surface 1. When the user rotates the second knob 28, the second knob 28 drives the second worm gear 26. The second worm gear 26 rotates with the cooperation of the third fixing block 27. While the second worm gear 26 rotates, it drives the second worm wheel 25. The second worm wheel 25 drives the third rotating shaft 23. The third rotating shaft 23 rotates with the cooperation of the second fixing block 24. While the third rotating shaft 23 rotates, it drives the adjustment frame 2. The angle of the left and right sides of the fixed box 3 is adjusted with the cooperation of the adjustment frame 2.

[0032] like Figure 4 As shown, damping pads 29 are provided on the side of the fixing claw 5 near the pole body 4. The damping pads 29 are fixedly connected to the fixing claw 5, which improves the friction between the contact surface of the fixing claw 5 and the pole body 4.

[0033] like Figure 1 and Figure 2As shown, support rods 30 are fixedly connected to the four corners of the bottom of the tabletop 1, support blocks 31 are fixedly connected to the bottom of the support rods 30, and anti-slip pads 32 are fixedly connected to the bottom of the support blocks 31, which improves the stability of the device placement and prevents the device from shifting.

[0034] Working principle: The user places the pole body 4 at the center of the fixing box 3, and then starts the brake motor 9. The output end of the brake motor 9 drives the first rotating shaft 10. The first rotating shaft 10 rotates and drives the first bevel gear 11. The first bevel gear 11 drives two second bevel gears 12. The second bevel gears 12 drive the rotating sleeve 13. The rotating sleeve 13 rotates and drives the flat screw disc 33. The flat screw disc 33 pushes the moving block 6 through the flat threads on its surface. The moving block 6 slides towards the pole body 4 through the cooperation of the fixing box 3. As the moving block 6 slides, it drives the pole body 4. The moving fixing claw 5, in turn, clamps and fixes the pole body 4 through the cooperation of eight fixing claws 5. It can stably clamp and limit the poles of different diameters, preventing the poles from shaking. This solves the problem that although the existing prestressed concrete pole tensioning and anchoring devices can limit the poles, the curvature of the internal limiting components is not adjustable. In addition, the poles are of various types, which makes the contact area between the limiting components and the poles small and the fit poor when limiting poles of different diameters. This results in the poles being clamped less steadily and prone to shaking.

[0035] The user rotates the first knob 21, which drives the first worm gear 19. The first worm gear 19 rotates in conjunction with the first fixing block 20. Simultaneously, the rotation of the first worm gear 19 drives the first worm wheel 18, which in turn drives the second rotating shaft 16. The second rotating shaft 16 then drives the fixed box 3, thereby adjusting the front-to-back angle of the fixed box 3. Rotating the second knob 28 drives the second worm gear 26, which rotates in conjunction with the third fixing block 27. Simultaneously, the rotation of the second worm gear 26 drives the second worm wheel 25, which in turn drives the third rotating shaft 23. The third rotating shaft 23 rotates in conjunction with the second fixing block 24, and simultaneously drives the adjusting frame 2. Through the adjustment frame 2, the left and right angles of the fixed box 3 are adjusted. This allows for multi-angle adjustment of the fixed box 3 on uneven ground to ensure it is level, thus ensuring the pole remains vertical, improving practicality.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
