[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Please see Figure 1-4 A bridge construction formwork includes a fixed plate 1 and a working basket 14. A suspension part 2 is fixedly installed on the top wall of the fixed plate 1, and an expansion bolt 17 is screwed onto the suspension part 2. Fixed seats 7 are fixedly installed on both sides of the front side wall of the fixed plate 1, and a guide rail 8 is fixedly installed between the two fixed seats 7. Multiple sets of moving parts 16 are fixedly installed on the rear side wall of the working basket 14. The moving parts 16 are provided with through holes, and the guide rail 8 is slidably connected to the through holes. A fixed arm 5 is fixedly installed on the front side wall of the fixed plate 1 above the guide rail 8. A driving assembly is installed inside the working basket 14, and an escape assembly is installed on the fixed arm 5. The driving assembly can drive the working basket 14 to move on the guide rail 8 via the moving parts 16, thereby adjusting the position of the working basket 14 to facilitate the construction of the bridge. The escape assembly allows workers to escape quickly in case of emergency.

[0024] Please see Figure 1The aforementioned driving component can be any type. This application provides an embodiment in which the driving component includes a threaded rod 9, a worm gear 12, and a worm 13. The threaded rod 9 is rotatably disposed between the left and right inner walls of the work basket 14. A threaded hole is provided on the fixed arm 5, and the threaded rod 9 is threadedly connected to the threaded hole. The worm gear 12 is fixedly disposed near the left inner wall of the work basket 14. A fixed frame 10 is fixedly disposed on the left inner wall of the work basket 14. The worm 13 is rotatably disposed between the rear side wall of the fixed frame 10 and the inner wall of the work basket 14. The worm 13 and the worm gear 12 mesh with each other. By rotating the worm 13, the worm gear 12 and the threaded rod 9 rotate synchronously, thereby driving the work basket 14 to move on the fixed arm 5 through the thread. Through the cooperation of the worm gear 12 and the worm 13, a self-locking mechanism can be formed to prevent the work basket 14 from moving passively.

[0025] Please see Figure 1 Furthermore, it also includes a handwheel 11. The handwheel 11 is rotatably mounted on the front side wall of the fixed frame 10. The handwheel 11 is fixedly connected to the end of the worm gear 13. With the addition of the handwheel 11, the worm gear 13 can be driven to rotate more conveniently.

[0026] Furthermore, the outer wall of the handwheel 11 is provided with anti-slip texture. As an extension, in order to prevent the handwheel 11 from loosening and rotating, multiple threaded holes can be opened on the handwheel 11. The multiple threaded holes are axially aligned with the fixed frame 10. A screw is threaded into one of the threaded holes. The screw is relatively long and has a hand-tightening cap at the end. The screw can be turned by the hand-tightening cap so that the end of the screw is tightly pressed against the surface of the fixed frame 10, thereby forming a locking force. This can prevent the handwheel 11 from loosening and rotating to a certain extent. In order to improve anti-slip performance, a rubber sleeve can be fixed to the end of the screw to increase friction.

[0027] Please see Figure 1-2 The aforementioned escape components can be of any type. This application provides an embodiment in which the escape components include an escape ladder 6 and a slide 4. The addition of the escape ladder 6 facilitates the quick escape of workers to the bridge deck. A slide 4 is fixedly installed on the front wall of the escape ladder 6. The top of the escape ladder 6 bends towards the top wall of the suspension part 2. A slide rail 3 is fixedly installed on the top wall of the suspension part 2, and the slide 4 is slidably connected within the slide rail 3. When the work basket 14 moves, the escape ladder 6 can move synchronously on the slide rail 3 via the slide 4, increasing the stability of the escape ladder 6.

[0028] Please see Figure 1-4 Furthermore, a fall protection net 15 is fixedly installed on the outer wall near the bottom of the work basket 14. The addition of the fall protection net 15 can further increase the safety of this structure.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
