Description

Technical Field

[0001] This utility model relates to the field of precast T-beam technology, and in particular to an electric sliding frame for positioning the reinforcing bars of precast T-beams. Background Technology

[0002] The transition section of a precast T-beam is a special design section in a bridge structure used to achieve linear changes in bridge width or beam thickness. The transition section can optimize the stress performance of the T-beam, reduce construction joint and joint stress, and at the same time improve the overall aesthetics of the bridge and adapt to complex alignment requirements.

[0003] When the length of the precast beam changes, the length of the steel reinforcement jig used to prepare the precast beam needs to be adjusted. This causes the positioning grooves of the transition section of the steel reinforcement jig to frequently change position according to the beam length. The traditional method of connecting the transition section of the steel reinforcement jig is welding. When the position needs to be adjusted, the original welding point needs to be cut and then re-welded after the adjustment. This makes the process cumbersome, and the jig is repeatedly cut, which also has a significant impact on the appearance and durability.

[0004] Therefore, it is necessary to develop a new electric sliding jig for positioning the reinforcing bars of precast T-beams to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide an electric sliding jig for positioning the rib reinforcement of a precast T-beam, which facilitates adjusting the position of the gradually changing section of the reinforcement jig according to the beam length.

[0006] To solve the above-mentioned technical problems, the electric sliding jig for positioning precast T-beam rib reinforcement provided by this utility model includes: multiple fixed platforms, a base plate welded to the bottom end of each fixed platform, and a second positioning plate welded to the side wall of each fixed platform; a first positioning plate welded to the top of the fixed platform located in the middle position, and guide rails installed on the tops of the fixed platforms located on both sides; multiple sliding seats slidably connected to the surface of the guide rails, the sliding seats being fixedly connected to the adjusting positioning plate, the adjusting positioning plate being composed of a butt joint section and a transition section, one side of the butt joint section being aligned with one side of the first positioning plate; the width of the transition section gradually decreasing; positioning grooves are provided on the side walls of the first positioning plate, the second positioning plate, the adjusting positioning plate, and the base plate; a toothed plate is installed on the surface of the adjusting positioning plate, a motor is installed on the surface of one of the fixed platforms, a gear is installed on the output shaft of the motor, and the gear meshes with the toothed plate.

[0007] Preferably, a partition is vertically mounted on the surface of the adjusting positioning plate, and the partition separates the toothed plate from the positioning groove.

[0008] Preferably, the positioning grooves on the surfaces of the first positioning plate and the adjusting positioning plate engage with the web ribs, and the positioning grooves on the surfaces of the second positioning plate and the bottom plate engage with the horseshoe ribs.

[0009] Preferably, a support frame is installed on the side wall of the fixed platform to support the horizontal reinforcement bars. The horizontal reinforcement bars, the web reinforcement bars, and the horseshoe reinforcement bars are welded together to form a precast T-beam rib cage.

[0010] Preferably, the sidewall of the slide is threadedly connected to the screw, and the screw abuts against and presses against the surface of the guide rail.

[0011] Preferably, mounting plates are installed on both sides of the slide, and a rubber roller and a roller brush are rotatably connected to the side wall of the mounting plate. The elastic rubber roller is rolledly connected to the guide rail. On the same mounting plate, the rotation direction of the rubber roller is opposite to the rotation direction of the roller brush.

[0012] Preferably, the mounting plate has an internal rotating connection between a first gear and a second gear that mesh with each other, and the first gear is fixedly connected to the rubber roller; a belt shaft is installed on one side of the second gear and the roller brush, and the belt shafts are connected by a belt.

[0013] Compared with related technologies, the electric sliding jig for positioning the precast T-beam rib reinforcement provided by this utility model has the following advantages: This utility model provides an electric sliding jig for positioning the rib reinforcement of precast T-beams. When the length of the precast T-beam changes, the position of the transition section of the precast T-beam changes. When the motor is turned on, the motor drives the gear to rotate, and the gear pushes the toothed plate and the adjusting positioning plate to move along the guide rail. The connecting section of the adjusting positioning plate moves above the first positioning plate, adjusting the overlap length between the first positioning plate and the connecting section, changing the position of the transition section, thereby adapting to the overlapping of precast T-beam rib reinforcement cages of different lengths. This facilitates construction by workers, avoids the original cutting and positioning work, speeds up production efficiency, and extends the service life of the jig. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figures 1 to 7 , Figure 1 A schematic diagram of a preferred embodiment of the electric sliding frame for positioning the precast T-beam rib reinforcement provided by this utility model; Figure 2 for Figure 1 The side view of the fixed platform structure shown; Figure 3 for Figure 1 The top view of the adjustable positioning plate structure is shown below; Figure 4 for Figure 1 The diagram shows the structure of the adjustment and positioning plate. Figure 5 for Figure 2 The diagram shows an enlarged view of the structure at point A. Figure 6 for Figure 5 The diagram shows the internal structure of the slide. Figure 7 for Figure 6The diagram shows the internal structure of the mounting plate. A precast T-beam rib reinforcement positioning electric sliding frame includes multiple fixed platforms 1. A base plate 6 is welded to the bottom of each fixed platform 1, and a second positioning plate 3 is welded to the side wall of each fixed platform 1. A first positioning plate 2 is welded to the top of the fixed platform 1 located in the middle position, and guide rails 13 are installed on the tops of the fixed platforms 1 located on both sides. Multiple sliding blocks 15 are slidably connected to the surface of the guide rails 13. The sliding blocks 15 are fixedly connected to an adjusting positioning plate 4. The adjusting positioning plate 4 consists of a butt joint section 41 and a transition section 42. One side of the butt joint section 41 is aligned with one side of the first positioning plate 2. The width of the transition section 42 gradually decreases. Positioning grooves 11 are provided on the side walls of the first positioning plate 2, the second positioning plate 3, the adjusting positioning plate 4, and the base plate 6. A toothed plate 44 is installed on the surface of the adjusting positioning plate 4. A motor 5 is installed on the surface of one of the fixed platforms 1, and a gear 12 is installed on the output shaft of the motor 5, with the gear 12 meshing with the toothed plate 44. When the length of the precast T-beam changes, the position of the transition section of the precast T-beam changes accordingly. The motor 5 is turned on, and its direction of rotation is controlled, controlling the movement direction of the adjusting positioning plate 4. The motor 5 drives the gear 12 to rotate, and the gear 12 pushes the toothed plate 44 and the adjusting positioning plate 4 to move along the guide rail 13. The connecting section 41 of the adjusting positioning plate 4 moves above the first positioning plate 2, adjusting the overlap length between the first positioning plate 2 and the connecting section 41, changing the position of the transition section 42. This allows for the overlapping of precast T-beam rib reinforcement cages of different lengths, facilitating worker construction, avoiding the original cutting and positioning work, accelerating production efficiency, and extending the service life of the jig.

[0018] The adjustment positioning plate 4 is vertically mounted with a partition 43, which separates the toothed plate 44 from the positioning groove 11 in order to reduce the interference encountered by the gear 12 in driving the toothed plate 44 to move.

[0019] The positioning grooves 11 on the surfaces of the first positioning plate 2 and the adjusting positioning plate 4 engage the web ribs 9, and the positioning grooves 11 on the surfaces of the second positioning plate 3 and the base plate 6 engage the horseshoe-shaped ribs 10. A support frame 7 is installed on the side wall of the fixed platform 1, supporting the horizontal ribs 8. The horizontal ribs 8, the web ribs 9, and the horseshoe-shaped ribs 10 are welded together to form a precast T-beam rib cage. The support frame 7 provides support to the horizontal ribs 8, facilitating welding between the horizontal ribs 9, the web ribs 9, and the horseshoe-shaped ribs 10. To facilitate the first positioning plate 2 fixing the web ribs 9 in the normal section, the adjusting positioning plate 4 fixing the web ribs in the transition section, and the second positioning plate 3 and the base plate 6 fixing the horseshoe-shaped ribs 10.

[0020] The side wall of the slide block 15 is threadedly connected to the screw 14, and the screw 14 abuts against and presses against the surface of the guide rail 13. When the adjusting positioning plate 4 moves, the adjusting positioning plate 4 drives the slide block 15 to move on the surface of the guide rail 13. When it is necessary to fix the adjusting positioning plate 4, the screw 14 is rotated to press the guide rail 13, thereby fixing the position of the slide block 15 and preventing the adjusting positioning plate 4 from shaking during use.

[0021] Mounting plates 17 are installed on both sides of the slide block 15. A rubber roller 18 and a brush 16 are rotatably connected to the sidewalls of the mounting plates 17. The elastic rubber roller 18 is rolled between itself and the guide rail 13. On the same mounting plate 17, the rotation direction of the rubber roller 18 is opposite to that of the brush 16. A first gear 19 and a second gear 20 are rotatably connected inside the mounting plate 17, meshing with each other. The first gear 19 is fixedly connected to the rubber roller 18. A belt shaft 21 is installed on one side of both the second gear 20 and the brush 16, and the belt shafts 21 are connected by a belt 22. Due to the welding of the reinforcing bars, a small amount of welding slag will fall onto the surface of the guide rail 13 during the welding process. (See attached...) Figure 6 and attached Figure 7 As shown, when the slide 15 moves to the left, under the weight of the adjusting positioning plate 4 and the slide 15, the rubber roller 18 contacts the surface of the guide rail 13. When the slide 15 moves, it pushes the left rubber roller 18 to rotate counterclockwise. The rubber roller 18 drives the first gear 19 to rotate, and the first gear 19 drives the second gear 20 to rotate clockwise. Through the belt shaft 21 and the belt 22, the roller brush 16 rotates clockwise. When the slide 15 moves to the left, the roller brush 16 located on the left side of the slide 15 rotates clockwise on the surface of the guide rail 13, pushing the impurities on the surface of the guide rail 13 outward, preventing impurities from entering the interior of the slide 15, reducing the movement resistance of the slide 15, and facilitating the operation of the adjusting positioning plate 4. Similarly, when the slide 15 moves to the right, the roller brush 16 located on the right side of the slide 15 rotates counterclockwise to clean the guide rail 13, facilitating the movement of the slide 15.
