[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0024] like Figures 1-5 As shown, a bridge web and top and bottom plate reinforcing rib marking and positioning device includes a locking telescopic rod 1. Both ends of the locking telescopic rod 1 are fixedly connected to locking angle adjustment parts 2. Each of the two locking angle adjustment parts 2 is fixedly connected to a moving part 3. One locking angle adjustment part 2 is fixedly connected to a locking winding part 5, and the other locking angle adjustment part 2 is fixedly connected to a side bracket 4. At least two steel wires 6 are wound inside the locking winding part 5. One end of the steel wire 6 is a movable end, which extends out of the locking winding part 5 and the side bracket 4 and is fixed. Multiple movable marking pens 7 are installed on the outside of the two steel wires 6, and the marking pens 7 can be locked at different positions on the steel wires 6.
[0025] When marking and positioning the stiffening ribs on the top or bottom plate of the bridge web unit 8, the two moving parts 3 are brought into contact with the inner walls on both sides of the bridge web unit 8 to position the locking telescopic rod 1 and the steel wire 6. Then, the positions of multiple marking pens 7 are adjusted so that the multiple marking pens 7 are respectively opposite to the positions of the multiple stiffening ribs to be marked. After the positions of the marking pens 7 are adjusted, the locking telescopic rod 1 is moved inside the bridge web unit 8 to move the marking pens 7, thus completing the marking of the multiple stiffening ribs to be marked. The multiple marking pens 7, through the contact between the moving parts 3 and the side walls of the bridge web unit 8, can complete the left and right positioning of the locking telescopic rod 1 and the steel wire 6, thereby completing the movement guidance of the marking pens 7 and reducing the difficulty of marking.
[0026] Here, a size scale is provided on the outside of the steel wire 6, which makes it easy to determine the position of the marking pen 7.
[0027] like Figures 1-2 As shown, in some embodiments, the locking telescopic rod 1 includes a sleeve 9, with inner rods 10 slidably connected to both ends of the sleeve 9. The two inner rods 10 are respectively fixedly connected to two locking angle adjustment parts 2. The two ends of the sleeve 9 are threaded with first locking screws 11. When the inner rods 10 slide, the total length of the locking telescopic rod 1 can be adjusted to control the distance between the two moving parts 3. After adjustment, the position of the inner rods 10 can be locked by the first locking screws 11.
[0028] like Figures 1-3 As shown, in some embodiments, the locking angle adjustment component 2 includes a U-shaped frame 12 fixedly connected to the end of the inner rod 10. A rotating rod 13 and a first worm gear 15 are rotatably connected to the U-shaped frame 12. A first worm wheel 14 and a rotating arm 16 are fixedly connected to the outer side of the rotating rod 13. The first worm wheel 14 and the first worm gear 15 are meshed together. By rotating the first worm gear 15, the first worm wheel 14 and the rotating rod 13 can be driven to rotate. After rotation, the rotating rod 13 can be locked by the first worm gear 15. The rotating arm 16 and the moving part 3 are fixedly connected. When the rotating rod 13 rotates, it can drive the moving part 3 to rotate together, thereby adapting to the angle of the side wall of the bridge web unit 8.
[0029] In some embodiments, an angle scale 17 located outside the rotating rod 13 is fixedly connected to the side of the U-shaped frame 12, and an indicator needle 18 is fixedly connected to the outside of the rotating rod 13. The rotation angle of the side plate 19 can be determined by observing the indicator needle 18.
[0030] like Figures 1-3 As shown, in some embodiments, the moving part 3 includes a side plate 19 fixedly connected to the rotating rod 13. The side plate 19 can be positioned by abutting against the side wall of the bridge web unit 8, thereby positioning the locking telescopic rod 1 and the steel wire 6.
[0031] In other embodiments, a plurality of first wheel bodies 20 are fixedly connected to the side of the side plate 19, and at least two second wheel bodies 21 are fixedly connected to the upper and lower sides of the side plate 19. During the movement of the side plate 19, the arrangement of the first wheel bodies 20 and the second wheel bodies 21 can reduce the wear between the side plate 19 and the bridge web unit 8.
[0032] like Figure 1 and Figure 4 As shown, in some embodiments, the marking pen 7 includes a slide 22 slidably connected to the outside of the two steel wires 6. A second locking screw 23 is threaded onto the slide 22. After the slide 22 has slid outside the steel wires 6, the second locking screw 23 can be rotated to make the second locking screw 23 abut against the steel wires 6, thereby locking and positioning the slide 22.
[0033] An inner sleeve 26 is installed on the lower side of the slide 22. A marker 27 is inserted into the inner sleeve 26. A third locking screw 28 is threaded on the outer side of the inner sleeve 26. At this time, the marker 27 can be replaced as needed. After replacement, the marker 27 can be locked by the third locking screw 28.
[0034] In some further embodiments, an outer sleeve 24 is fixedly connected to the lower side of the slide 22, and a return spring 25 is fixedly connected inside the outer sleeve 24. An inner sleeve 26 is slidably connected inside the outer sleeve 24, and the upper end of the inner sleeve 26 is fixedly connected to the lower end of the return spring 25. In use, the return spring 25 applies a downward pushing force to the inner sleeve 26 and the marker 27, so that multiple markers 27 can effectively contact the bridge web unit 8.
[0035] Among them, such as Figures 1-2 and Figure 5 As shown, the locking winding component 5 includes a housing 29 fixedly connected to the locking angle adjustment component 2. A winding shaft 30 is rotatably connected inside the housing 29. Both steel wires 6 are wound on the outside of the winding shaft 30. A second worm gear 32 is rotatably connected to the housing 29. A second worm wheel 31 is fixedly connected to the outside of the winding shaft 30. The second worm wheel 31 and the second worm gear 32 are meshed together. At this time, by rotating the second worm gear 32, the winding shaft 30 can be rotated through the second worm wheel 31 to unwind or wind the steel wires 6. After the winding shaft 30 has rotated, it can be locked by the second worm wheel 31 and the second worm gear 32.
