[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] like Figure 1 As shown, this embodiment discloses a bridge erecting machine with a stabilizing device, including a machine body. The machine body includes a support device, a main beam 1, a connecting frame 2, and a guide beam 3. The main beam 1 is mounted on the support device, the connecting frame 2 is mounted on the main beam 1, and the guide beam 3 is mounted on the connecting frame 2. A crane and an auxiliary crane (not shown in the figure) are mounted on the guide beam 3. To enable the crane and auxiliary crane to move in opposite directions, the guide beams 3 of multiple connecting frames 2 are connected by bolts. The specific connection structure is well-known to those skilled in the art, and therefore will not be described in detail in this embodiment.

[0022] The support device includes a first base plate 11, a telescopic plate located above the first base plate 11, and a fixed plate 13 set on the telescopic plate; the support device also includes a second base plate 14, a cylinder 15 located on the second base plate 14, and a sliding plate 16 installed on the cylinder 15 (the sliding function of the sliding plate 16 is designed to adapt to the needs of erecting various beam types such as main line beams and platform beams, and to meet the needs of feeding beams at different positions, including front, middle, and rear).

[0023] The main structure of the bridge erecting machine also includes a stabilizing device, which consists of a hydraulic cylinder 4, a support rod 5 attached to the output end of the hydraulic cylinder 4, a top rod 6 mounted on the support rod 5, and a support seat 7 mounted on the top rod 6. A fixing plate 13 is fixedly connected to the main beam 1, and the hydraulic cylinder 4 is fixedly connected to the first base plate 11. The support seat 7 has a support groove 8. The support rod 5 supports the main beam 1, while the support seat 7 supports the guide beam 3. After the guide beams 3 between the connecting frames 2 are bolted together, the hydraulic cylinder 4 is activated, driving the support rod 5 and support seat 7 to rise. The support rod 5 further stabilizes the main beams 1 on both sides of the connecting frame 2. Simultaneously, after the support seat 7 rises, the connection point of the guide beam 3 is embedded in the support groove 8, and the guide beam 3 is stably supported by the support seat 7. Compared with simple bolt fixing, this method offers greater stability and a relatively lower risk of breakage.

[0024] To facilitate the installation and removal of bolts at the connection of guide beam 3, this embodiment employs a sliding connection between the top rod 6 and the support rod 5. The support rod 5 has a groove 9 inside, and the bottom end of the top rod 6 extends into the groove 9, allowing it to slide freely within it. A lead screw 10 is installed within the groove 9; this lead screw 10 is rotatable and passes through the support rod 5, forming a threaded connection. When the hydraulic cylinder 4 drives the support seat 7 to descend, rotating the lead screw 10 causes the top rod 6 and support seat 7 to move, thus moving the support seat 7 away from the connection of guide beam 3 and creating sufficient space for bolt installation and removal. This design is more convenient.

[0025] like Figure 2 As shown, a slider 17 is mounted on the sliding plate 16, and a slide rail 18 matching the slider 17 is provided at the bottom of the main beam 1. The cooperation between the slider 17 and the slide rail 18 enables the sliding plate 16 to slide. To enhance the stability between the sliding plate 16 and the main beam 1 in a static state, a fixing device for positioning with the main beam 1 is specially designed on the sliding plate 16. This fixing device consists of slots 19 distributed in the slide rail 18, a locking strip 20 embedded in the slider 17, and a lifting assembly disposed in the sliding plate 16. The lifting assembly can drive the locking strip 20 to disengage from or enter the slot 19. When the sliding plate 16 needs to move, the lifting assembly will cause the locking strip 20 to disengage from the slot 19; and when stable support is required, the lifting assembly will cause the locking strip 20 to engage with the slot 19, thereby achieving stable support for the sliding plate 16. Figure 3As shown, in this embodiment, the lifting assembly includes a pull rod 21 movably connected to the sliding plate 16 and a spring 22 disposed within the sliding plate 16 and connected to the pull rod 21. Both ends of the pull rod 21 extend into the interior of the sliding plate 16, and a locking strip 20 is fixedly connected to the pull rod 21, enabling the pull rod 21 to control the lifting and lowering of the locking strip 20. The number of springs 22 and locking strips 20 can be adjusted according to actual needs. By pressing down on the pull rod 21, the elastic force of the spring 22 can be overcome, causing the locking strip 20 to disengage from the locking slot 19; after releasing the pull rod 21, the locking strip 20 quickly engages with the locking slot 19 under the action of the spring force of the spring 22, thereby ensuring stable support of the sliding plate 16. This design significantly improves the overall stability of the bridge construction erecting machine.
