Description

Technical Field

[0001] This utility model relates to the field of cement pole preparation technology, specifically to a precision positioning fixture for cement pole reinforcement cage fabrication. Background Technology

[0002] As the core load-bearing structure of a concrete pole, the positioning accuracy of the reinforcing cage directly determines the pole's mechanical properties and durability. In traditional construction methods, the positioning of the reinforcing cage relies primarily on manual experience, using methods such as temporary fixing with spacers or welding auxiliary positioning ribs. While these methods are simple to operate, they are insufficient for the high-precision positioning requirements of slender cylindrical concrete poles, especially for large poles exceeding 10 meters in height, where positioning quality directly impacts project safety.

[0003] The current rebar cage positioning process has obvious technical defects: First, manual adjustment is difficult to ensure the uniform distribution of the main reinforcement bars; second, the temporary fixing method has poor stability and is prone to displacement during the weaving process, causing the pole to be eccentrically compressed. To address this, we propose a precision positioning fixture for cement pole rebar cage weaving. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a precise positioning fixture for weaving cement pole steel cages, which can ensure the uniform distribution of the main reinforcement bars during weaving and avoid displacement during weaving, thus effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision positioning fixture for the fabrication of cement pole reinforcement cages, including an installation ring and a support assembly;

[0006] Mounting ring: The circumferential surface has evenly distributed strip-shaped openings, and the front end of the mounting ring is equipped with a rotating component;

[0007] Support assembly: includes a movable frame, a threaded rod, a first bevel gear, and a support hole. The movable frame is slidably connected inside the strip-shaped opening. A rotating hole is opened inside the strip-shaped opening, and a rotating shaft is rotatably connected inside the rotating hole. The first bevel gear is fixed on the end face of the rotating shaft outside the strip-shaped opening. All the first bevel gears are located inside the mounting ring. A threaded hole is opened on the rear side of the movable frame, and the threaded rod is threaded into the threaded hole. A support hole is opened on the side of the movable frame away from the first bevel gear. A fixing assembly is installed on the side of the movable frame. The rotating assembly is connected to all the first bevel gears. The main reinforcement of the cement pole is supported by the support assembly.

[0008] Furthermore, the fixing component includes an internally threaded tube, a threaded post, and a dialing plate. A fixing hole is provided on the side of the movable frame. The threaded tube is fixed inside the fixing hole. The threaded post is connected to the internal thread of the threaded tube. The dialing plate is fixed on the end face of the threaded post located outside the internally threaded tube. The main reinforcement of the cement pole is fixed by setting the fixing component.

[0009] Furthermore, the rotating assembly includes a fixed frame, a motor, a second bevel gear, and support legs. The fixed frame is fixed to the front end of the mounting ring, and the motor is installed inside the fixed frame. The second bevel gear is fixed on the output shaft of the motor, and the second bevel gear meshes with all the first bevel gears. Two corresponding support legs are fixed to the lower side of the fixed frame. The input end of the motor is electrically connected to the output end of an external control switch. By setting the rotating assembly to drive all the first bevel gears to rotate, the position of all the moving frames can be adjusted, thereby facilitating the adaptation to the main reinforcement bars of cement poles with different spacings.

[0010] Furthermore, an anti-slip ring is fixed on the circumferential surface of the dial, and the anti-slip ring has evenly distributed anti-slip grooves on its circumferential surface. The anti-slip ring facilitates the user's rotation of the dial.

[0011] Furthermore, a base plate is fixed to the lower side of the two outriggers, and four corresponding fixing holes are provided on the edge of the base plate. The two outriggers are fixed by setting the base plate and fixing holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This precision positioning fixture for cement pole rebar cage weaving has the following advantages:

[0013] 1. The combination of bevel gear linkage mechanism and modular moving frame is adopted. The synchronous radial adjustment of all support points is achieved by motor drive. While ensuring the uniform distribution of the main reinforcement around the circumference, it can adapt to the preparation requirements of steel cages with different diameters and specifications, which significantly improves the process adaptability of the equipment.

[0014] 2. The composite fixing structure of support holes and threaded columns is adopted. While providing support for the main rib positioning, the threaded push-type clamping mechanism realizes three-dimensional locking, completely eliminating the slippage of the main rib during the weaving process.

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.

[0020] Please see Figure 1-3 This embodiment provides a technical solution: a precision positioning fixture for the fabrication of cement pole reinforcement cages, including an installation ring 1 and a support component 3;

[0021] Mounting ring 1: A uniformly distributed strip-shaped opening 2 is provided on the circumferential surface. A rotating component 5 is installed at the front end of the mounting ring 1. The rotating component 5 includes a fixed frame 51, a motor 52, a second bevel gear 53, and support legs 54. The fixed frame 51 is fixed at the front end of the mounting ring 1. The motor 52 is installed inside the fixed frame 51. The second bevel gear 53 is fixed on the output shaft of the motor 52. The second bevel gear 53 meshes with all the first bevel gears 33. Two corresponding support legs 54 are fixed on the lower side of the fixed frame 51. The input end of the motor 52 is electrically connected to the output end of an external control switch. By setting the rotating component 5 to drive all the first bevel gears 33 to rotate, the position of all the moving frames 31 is adjusted, so as to easily adapt to the main reinforcement of cement poles with different spacing.

[0022] Support assembly 3 includes a movable frame 31, a threaded rod 32, a first bevel gear 33, and a support hole 34. The movable frame 31 is slidably connected inside the slot 2. A rotating hole is opened inside the slot 2, and a rotating shaft is rotatably connected inside the rotating hole. The first bevel gear 33 is fixed on the end face of the rotating shaft outside the slot 2. All the first bevel gears 33 are located inside the mounting ring 1. A threaded hole is opened on the rear side of the movable frame 31, and the threaded rod 32 is threaded into the inside of the threaded hole. A support hole is opened on the side of the movable frame 31 away from the first bevel gear 33. 34. A fixing component 4 is installed on the side of the movable frame 31. The rotating component 5 is connected to all the first bevel gears 33. The fixing component 4 includes an internal threaded tube 41, a threaded post 42 and a dial 43. A fixing hole is opened on the side of the movable frame 31. The threaded tube 41 is fixed inside the fixing hole. The threaded post 42 is connected to the internal thread of the threaded tube 41. The dial 43 is fixed on the end face of the threaded post 42 outside the internal threaded tube 41. The main reinforcement of the cement pole is fixed by setting the fixing component 4, and the main reinforcement of the cement pole is supported by setting the support component 3.

[0023] Among them, an anti-slip ring 6 is fixed on the circumferential surface of the dial 43, and the anti-slip ring 6 has evenly distributed anti-slip grooves on its circumferential surface. The anti-slip ring 6 makes it convenient for users to rotate the dial 43.

[0024] Among them: a base plate 7 is fixed to the lower side of the two support legs 54, and four corresponding fixing holes 8 are opened on the edge of the base plate 7. The two support legs 54 are fixed by setting the base plate 7 and fixing holes 8.

[0025] The working principle of the precision positioning fixture for cement pole rebar cage fabrication provided by this utility model is as follows: Several installation ring 1 units are selected according to the design length of the main reinforcement and arranged at intervals along the axis of the main reinforcement. Each unit is anchored to the ground through the fixing holes 8 of the base plate 7 to ensure the concentricity of the multi-fixture system. After starting the motor 52 of the arbitrary rotation component 5, the second bevel gear 53 drives the first bevel gear 33 of all fixtures to rotate synchronously, and the threaded rods 32 of each unit rotate in linkage, so that the moving frame 31 on each installation ring 1 moves radially synchronously along the strip opening 2, realizing the proportional scaling of the array of support holes 34 of the multi-fixture, and completing the uniform adjustment of the circumferential spacing of the entire length of the main reinforcement. After the main reinforcement passes through all the support holes 34, the actuating disks 43 of each fixing component 4 are rotated in sequence. Through the axial feed of the threaded column 42 in the internal threaded tube 41, the main reinforcement passing through the multi-fixture is subjected to segmented radial compression, forming a distributed rigid constraint system, and finally realizing the dual control of the axial straightness and radial uniformity of the ultra-long rebar cage.
