[0001] This application relates to the field of bridge erecting machine traveling rail technology, and in particular to a device for preventing rail overturning. Background Technology

[0002] Bridge erecting machines are required during bridge girder erection. These machines typically travel on rails, and because they are in the bridge girder erection phase, the rails they travel on are usually not fixed.

[0003] Currently, during the construction of high-speed railway bridges, when the bridge erecting machine travels on non-fixed rail sections, it will experience lateral forces when crossing spans, erecting beams, or stopping, which poses a risk of the rails overturning or tipping over.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this application is to provide a device to prevent rail overturning, so as to solve or alleviate the problem that the lateral force generated when the bridge erecting machine travels on non-fixed rail sections can easily cause the rail to overturn and tip over.

[0011] Preferably, a limiting plate is connected between the ends of two adjacent arc plates, and the limiting plate fixes the maximum outward tilt angle of the lower end of the support leg.

[0012] Preferably, both ends of the adjusting column are provided with threaded sections, and the thread directions are opposite.

[0013] Two threaded sections converge toward the center of the adjusting column, and the two clamping plates are threadedly fitted onto the adjusting column through the two threaded sections.

[0032] Example 1: This example aims to provide a rail overturning prevention device. Its main function is to provide lateral support for the rail, so that it will not be affected by the lateral force of the bridge erecting machine and will not overturn or tip over, thus ensuring the stability of the rail.

[0033] Reference Figures 1-3 The system includes: a crossbeam 1, a pair of clamping plates 3, an adjusting column 4, and a reinforcing beam. The crossbeam 1 is either a cylindrical tube or a solid column. The crossbeam 1 is located above the rail, and the length direction of the crossbeam 1 is aligned with the width direction of the rail. A pair of legs 2 are obliquely erected at both ends of the crossbeam 1. The two adjacent legs 2 are symmetrically arranged about the crossbeam 1 so that the two adjacent legs 2 form a V-shape. A pair of arc plates 5 are provided at both ends of the crossbeam 1. The inner ring side of the arc plate 5 is welded and fixed around the bottom semicircle of the crossbeam 1, and the two adjacent arc plates 5 are spaced apart to form a hinge space. The upper end of the leg 2 is located in the hinge space so that the upper end of the leg 2 is hinged to the arc plate 5 through a pin. The hinge position is close to the end of the arc plate 5 to adjust the distance between adjacent legs 2. The purpose is to make the two legs 2 stand vertically to the ground, with a gap between the two legs 2, and this gap is exactly matched with the diameter of the adjusting column 4.

[0034] A pair of clamping plates 3 are erected between two support legs 2, and the upper ends of the two clamping plates 3 are slidably sleeved on the outside of the crossbeam 1. That is, the two clamping plates 3 can slide along the axial direction of the crossbeam 1. The lower inner side of the two clamping plates 3 is provided with corresponding clamping slots that are adapted to the top plate of the rail, so that the top plate of the rail can be clamped by the two clamping plates 3 approaching each other.

[0035] The adjusting column 4 is horizontally positioned directly below the crossbeam 1 to connect the two clamping plates 3 together. By rotating the adjusting column 4, the two clamping plates 3 can be synchronously displaced in opposite directions, allowing them to clamp or release the top plate of the rail. Specifically, both ends of the adjusting column 4 are provided with threaded sections in opposite directions. The two threaded sections converge towards the middle of the adjusting column 4, threading the two clamping plates 3 and the adjusting column 4 together. The length of the two threaded sections is sufficient to stably clamp the top plate of the rail with the two clamping plates 3. Furthermore, the maximum distance between the two clamping plates 3, which is adjusted by the adjusting column 4, is greater than the width of the top plate of the rail, so that the device can be placed and removed vertically.

[0036] A reinforcing beam is horizontally positioned between two adjacent support legs 2. Both ends of the reinforcing beam are connected to the two adjacent support legs 2 respectively. The end of the adjusting column 4 passes through the middle of the reinforcing beam and protrudes outward. The two adjacent support legs 2 are connected as one unit through the reinforcing beam and the adjusting column 4. At this time, the tilt angle of the two support legs 2 is at its maximum. In this state, the lower end of the support leg 2 is fully in contact with the ground to ensure stable support on the ground. Specifically, the middle of the support leg 2 is provided with a receiving opening 7. The receiving opening 7 faces the same direction as the extension direction of the track. The reinforcing beam is composed of two swing arms 8. The size of the receiving opening 7 is the same as the size of the swing arm 8. The ends of the two swing arms 8 that are close to each other are fitted together on the outside of the adjusting column 4. Thus, the two swing arms 8 are hinged as one unit with the adjusting column 4 as the pin. The ends of the two swing arms 8 that are far from each other are hinged in their respective receiving openings 7, and the hinge position is above the receiving opening 7.

[0037] Reference Figure 2 and Figure 3 When the device needs to be retracted, first rotate the adjusting column 4 to completely detach the two clamping plates 3 from the top plate of the rail. Then, lift the device upwards and remove it. Next, slide the two clamping plates 3 simultaneously to the right or left, first pulling one end of the adjusting column 4 away from the middle of the reinforcing beam. At this time, the two swing arms 8 of the reinforcing beam will automatically swing down into the corresponding receiving port 7. Repeat the above operation, then slide the two clamping plates 3 in the opposite direction, so that the other end of the adjusting column 4 is also pulled away from the middle of the other reinforcing beam. At this time, the two swing arms 8 of the other reinforcing arm will also automatically swing down into the corresponding receiving port. 7. Thus, both adjacent supports become vertical, greatly reducing the volume. The distance between the two adjacent supports in the vertical state is just enough to place the adjusting column 4. Based on this, the device can provide lateral support for the rail while also reducing its volume, which greatly facilitates its storage and carrying. It should be noted that the distance by which the two clamping plates 3 slide to one side along the axial direction of the crossbeam 1 must be much greater than the length of the adjusting column 4 protruding out of the middle of the reinforcing beam, so as to ensure that the end of the adjusting column 4 can be completely pulled out from the middle of the reinforcing beam.

[0038] In this embodiment, the end of the adjusting column 4 is a rectangular segment that is tapered so that the two clamping plates 3 can be tightened using tools such as wrenches. The purpose of tapering is to allow the end of the adjusting column 4 to be smoothly and completely removed from the middle of the reinforcing beam.

[0039] In use, the two clamping plates 3 are centered on the crossbeam 1, and the adjacent support legs 2 are tilted at their maximum extension angle. Place the device so that the middle position of the two clamping plates 3 corresponds to the top plate of the rail. Then, rotate the adjusting column 4 to bring the two clamping plates 3 closer together to clamp the top plate of the rail. Finally, use a tool to clamp the rectangular end of the adjusting column 4 and tighten it.

[0040] Example 2 aims to further improve the support strength of this device. Specifically, refer to... Figure 1 and Figure 2 A limiting plate 6 is welded between the ends of two adjacent arc plates 5. The limiting plate 6 fixes the angle at which the lower end of the support leg 2 tilts outward, and this angle is exactly the maximum tilting and unfolding angle of the support leg 2, so that the limiting plate 6 can work together with the reinforcing beam to provide support for the crossbeam 1, thus achieving a joint action.

[0041] The anti-rail overturning device provided in this embodiment can provide lateral support to the rail, so that the lateral force generated when the bridge erecting machine walks on the rail will not affect the stability of the rail, thereby eliminating the hidden danger of rail overturning or tipping over, and thus ensuring the stable movement of the bridge erecting machine on the rail. At the same time, the size of this device can be reduced, making it more convenient to store and carry. Since the rail length of the bridge erecting machine usually requires the installation of this device at intervals, and a large number of devices need to be placed, the effect is more obvious when there are a large number of devices.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
