DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0014] Embodiment: as Figures 1-4As shown, the present application provides a bridge formwork rapid positioning assembly, including a base 1, the top surface of the base 1 is fixedly installed with a plurality of frame bodies 2, the top surface of the base 1 is symmetrically provided with two moving rods 3, the middle part of the moving rod 3 is fixedly installed with a moving plate 32, the middle part of the moving plate 32 is fixedly installed with a drive rod 33, the base 1 is movably connected with a positioning rod 41, the base 1 is internally provided with a positioning hole 17, and the positioning rod 41 and the positioning hole 17 are in sliding fit. In actual use, the base 1 can be placed in a suitable position, and the base 1 is in U-shaped structure and the sliding fit of the convex strip 11 and the lap joint groove 12, so that the splicing combination between the plurality of bases 1 is facilitated, so as to adapt to different bridge formwork construction requirements. By injecting gas into the positioning hole 17 through the connecting hole 13, the positioning rod 41 will extend out of the positioning hole 17, and the installation ring 4 at the inner end of the positioning rod 41 and the spring 42 between the adjacent installation rings 4 can play a buffering and stabilizing role in the extension and retraction process of the positioning rod 41, so as to ensure the accuracy and reliability of positioning. The guide block 31 at the end of the moving rod 3 is in sliding fit with the sliding groove 21 in the frame body 2, when the drive rod 33 drives the moving plate 32 to move, the moving plate 32 will drive the two moving rods 3 to move along the sliding groove 21, so as to realize the rapid positioning and adjustment of the bridge formwork. At the same time, the laser emitting end 15 on one side of the outer wall of the base 1 and the laser receiving end 16 on the other side of the outer wall can be used to detect whether the installation position of the base 1 is accurate, if the laser receiving end 16 does not receive the laser signal emitted by the laser emitting end 15, it means that the position of the base 1 may be deviated and needs to be adjusted.

[0015] Further, in the present application, the base 1 is in U-shaped structure, and the convex strip 11 is fixedly installed on one side of the outer wall of the base 1, and the lap joint groove 12 is provided on the other side of the outer wall of the base 1, and the convex strip 11 and the lap joint groove 12 are in sliding fit. Through the sliding fit mode of the convex strip 11 and the lap joint groove 12, not only the splicing between the plurality of bases 1 is more compact, but also the stability of the whole positioning assembly can be effectively improved. During splicing, only the convex strip 11 of one base 1 is aligned with the lap joint groove 12 of another base 1, and then it is pushed gently, and the splicing can be completed, which is simple and convenient. Moreover, due to the close fit of the convex strip 11 and the lap joint groove 12, the base 1 can be prevented from shaking or displacing after splicing, so as to ensure the precision of bridge formwork construction.

[0016] Further, in the present application, the bottom base 1 is provided with a laser emitting end 15 on one side wall, and a laser receiving end 16 on the other side wall. A sleeve 14 is fixedly installed on the top surface of the bottom base 1, and a drive shaft 5 is sleeved in the sleeve 14. In the horizontal direction, the drive shaft 5 is clamped and matched with the sleeve 14 through a clamping plate 51. The arrangement of the laser emitting end 15 and the laser receiving end 16 provides accurate position reference for the installation of the bottom base 1. During the installation process, whether the position of the bottom base 1 is accurate can be quickly judged by observing whether the laser receiving end 16 receives a laser signal, greatly improving the installation efficiency. The clamping and matching of the sleeve 14 and the drive shaft 5 through the clamping plate 51 enables the drive shaft 5 to be stably installed in the sleeve 14 in the horizontal direction. This clamping method not only facilitates the installation and removal of the drive shaft 5, but also ensures that the drive shaft 5 will not loosen or deviate during operation, ensuring that the drive shaft 5 can stably transmit power. When positioning and adjusting the bridge formwork is needed, the drive shaft 5 can drive the moving rod 3 to move through cooperation with other components, thereby achieving accurate control of the bridge formwork. In addition, the clamping and matching of the drive shaft 5 and the sleeve 14 also has a certain flexibility, which can conveniently replace drive shafts 5 of different specifications according to different construction needs to adapt to various bridge formwork construction scenes. At the same time, during the use of the entire positioning assembly, the close cooperation and mutual cooperation between the components enable the bridge formwork rapid positioning assembly to efficiently and accurately complete the installation of the bridge module.

[0017] Further, a sliding groove 21 is formed in the frame body 2, and a guide block 31 is fixedly installed at the end of the moving rod 3. The guide block 31 is in sliding cooperation with the sliding groove 21. Through the design of sliding cooperation, the movement of the moving rod 3 in the frame body 2 is smoother and more stable. When the guide block 31 slides in the sliding groove 21, it can effectively prevent the moving rod 3 from shaking or deviating, ensuring the accuracy of its movement trajectory. When the driving rod 33 drives the moving plate 32 to move, the moving plate 32 will transmit power to the moving rod 3, and the cooperation of the guide block 31 and the sliding groove 21 ensures that the moving rod 3 can move along the predetermined path, thereby accurately positioning and adjusting the bridge formwork.

[0018] Further, in the present application, the inner end of the positioning rod 41 is fixedly installed with an installation ring 4, and the adjacent two installation rings 4 are elastically connected through a spring 42. The top surface of the bottom base 1 is provided with a connecting hole 13, which is in communication with the positioning hole 17. When gas is injected into the positioning hole 17 through the connecting hole 13, the corresponding positioning rod 41 will extend out of the positioning hole 17.

[0019] Further, in the present application, the elastic connection of the spring 42 enables the positioning rod 41 to adaptively adjust according to the actual situation during the extension and retraction process. When the positioning rod 41 extends out and contacts the bridge formwork, the spring 42 can buffer the impact force received by the positioning rod 41, avoid causing damage to the bridge formwork, and also ensure the close fit between the positioning rod 41 and the formwork, thereby improving the stability of positioning. Moreover, the elastic effect of the spring 42 can also help the positioning rod 41 to quickly reset when it is retracted, thereby preparing for the next positioning operation.

[0020] Obviously, various modifications and changes can be made to the present application by those skilled in the art without departing from the spirit and scope of the present application. Thus, it is intended that the present application cover the modifications and changes as long as they come within the scope of the claims of the present application and their equivalents.
