For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Please refer to Figures 1 to 6, A bridge erection machine anti-overturning device 1 and a bridge erection machine shown in a preferred embodiment of the present application. The device includes a reinforcement component 11, a stability component 12, an active stop portion 13, and a reverse buckling component 14. The reinforcement component 11 is arranged on the front outrigger 23 and the rear outrigger 25 for strengthening the foundation of the bridge erection machine. The stability component 12 is arranged at the front outrigger 23 for supporting the bridge erection machine. The active stop portion 13 is arranged on the longitudinal and transverse movement tracks of the front outrigger 23, the middle outrigger 24, and the overhead crane 22 for limiting the bridge erection machine during movement. The reverse buckling component 14 is arranged on the moving wheel boxes of the front outrigger 23, the middle outrigger 24, and the overhead crane 22 for limiting the moving wheel boxes to counteract the unbalanced moment.

[0031] According to the solution of the embodiment of the present invention, by setting the reinforcement component 11, the stability of the foundation of the bridge erection machine is enhanced, the stability component 12 is set to provide additional support, the active stop portion 13 is set to provide limit stop for the bridge erection machine during operation, and the reverse buckling component 14 is set to balance the unbalanced moment, thereby overall improving the moving stability and safety of the bridge erection machine in a complex construction environment.

[0032] The following will be described in detail with specific embodiments:

[0033] Please refer to Figure 2 , The reinforcement component 11 includes a steel chain sling and a parallel reinforcement truss 111. The steel chain sling is arranged at the front outrigger 23 for strengthening the connection between the guide rail and the capping beam. The parallel reinforcement truss 111 is arranged at the rear outrigger 25 for enhancing the overall stability of the bridge erection machine. The guide rail and the capping beam of the bridge erection machine are firmly connected by the steel chain sling, enhancing the foundation stability of the front outrigger 23 and preventing the bridge erection machine from tilting or shifting under high load or complex construction environment. The parallel reinforcement truss 111 improves the anti-overturning ability of the bridge erection machine by increasing the strength and stability of the rear outrigger 25, preventing the bridge erection machine from overturning or losing stability due to unstable factors during the beam slab erection process.

[0034] Please refer to Figure 1 and Figure 5 , The stability component 12 includes a through-hole inclined strut stabilizing rod 121 and a bridge inclined strut stabilizing rod 122 arranged at the front outrigger 23 for providing support and protection during the bridge crossing and erection process of the bridge erection machine. The through-hole inclined strut stabilizing rod 121 increases the stability of the bridge erection machine during through-hole by an inclined support structure, preventing the bridge erection machine from tilting when passing through bridge holes or uneven terrains. The bridge inclined strut stabilizing rod 122 is also arranged at the front outrigger 23 to further provide support and protection, ensuring that the bridge erection machine can operate stably during the beam slab erection process.

[0035] Please refer to Figures 3 to 6, the end of the active retaining part is an arc-shaped structure to buffer and offset the impact force generated by the moving wheel box. The arc-shaped design helps to smoothly guide the release of the impact force, avoiding the impact concentration and structural damage that may be caused by a right-angled structure. By buffering and dispersing the impact force, the bridge erecting machine can operate more smoothly under high load and reduce the unstable factors caused by the impact.

[0036] Please refer to Figures 3 to 6 , the anti-clamping component 14 includes two anti-clamping plates 141 arranged on both sides of the moving wheel box. The anti-clamping plate 141 is an inverted U-shaped structure, and the end of the anti-clamping plate 141 is provided with a barb, which is clamped on the longitudinal and transverse movement track. These anti-clamping plates 141 generate a reverse moment by clamping the track to offset the unbalanced moment caused by the unbalanced load of the bridge erecting machine, helping the bridge erecting machine to maintain balance and prevent tipping over.

[0037] An embodiment of the present invention also provides a bridge erecting machine, including a bridge erecting machine main body 2 and a bridge erecting machine anti-tipping device 1. As Figure 1 shown, the bridge erecting machine main body 2 includes a main beam 21, a trolley 22 arranged on the main beam 21, a front outrigger 23, a middle outrigger 24, and a rear outrigger 25. The other conventional structures of the bridge erecting machine will not be described in detail here.

[0038] Specifically, in this embodiment, as Figure 3 shown, a trolley 22 longitudinal movement wheel box and a trolley 22 stop part 131 are arranged on the trolley 22 longitudinal movement track, and trolley 22 anti-clamping plates 142141 are arranged on both sides of the trolley 22 longitudinal movement wheel box. As Figure 4 shown, a front outrigger transverse movement wheel box 232 and a front outrigger stop part 132 are arranged on the front outrigger transverse movement track 231, and front outrigger anti-clamping plates 143 are arranged on both sides of the front outrigger transverse movement wheel box 232. As Figure 6 shown, a middle outrigger transverse movement wheel box 242 and a middle outrigger stop part 133 are arranged on the middle outrigger transverse movement track 241, and middle outrigger anti-clamping plates 144 are arranged on both sides of the middle outrigger transverse movement wheel box 242. The active stop parts 13 and the anti-clamping components 14 corresponding to the longitudinal movement parts of the front outrigger 23, the longitudinal movement parts of the middle outrigger 24, and the transverse movement part of the trolley 22 will not be described in detail here.

[0039] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0040] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
