Description

A simple anti-tipping device for the traveling rails of a bridge erecting machine Technical Field

[0001] This utility model belongs to the field of bridge erection construction technology, specifically relating to a simple anti-tipping support for bridge erection machines. Background Technology

[0002] When carrying out bridge girder erection, bridge erection machines are often used. These machines typically travel on rails. Because the bridge girder erection is still in the process of construction, the rails on which the bridge erection machine travels are usually not fixed. When the bridge erection machine travels on a non-fixed rail section, there may be unsafe factors.

[0003] Currently, during the construction of high-speed railway bridges, the rails of the bridge erecting machines are not equipped with anti-overturning devices, which makes the bridge erecting machines susceptible to lateral stress, rail overturning, and overturning risks when crossing spans, erecting beams, or stopping. This poses a significant safety hazard to the bridge erecting machines in all states.

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

[0040] This embodiment aims to provide a simple anti-tipping device for the traveling rails of a bridge erecting machine. Its main function is to effectively ensure the stability of the traveling rails of the bridge erecting machine, prevent the rails from overturning, thereby avoiding the overturning of the bridge erecting machine and ensuring that the bridge erecting machine is in a stable state under any working condition.

[0041] Referring to Figures 1 and 2, the simple anti-tipping device for the traveling rail of this bridge erecting machine mainly consists of a cantilever beam 1, a support frame, and a pair of clamping plates 2. The cantilever beam 1 is horizontally positioned above the rail, and supports are installed at both ends of the cantilever beam 1. The support frame has two working states: positioning support and moving support. To cope with these two working states, the support frame consists of a positioning support frame and a moving support frame. The clamping plates 2 are respectively erected on both sides of the rail, and their upper ends are fitted over the outside of the cantilever beam 1, allowing the clamping plates 2 to slide along the length of the cantilever beam 1. To prevent the clamping plates 2 from rotating, the cantilever beam 1 has a rectangular structure. An adjusting screw 3 is horizontally installed between the cantilever beam 1 and the rail. The two ends of the adjusting screw 3 are respectively threaded onto the two clamping plates 2. Because the two ends of the adjusting screw 3 have opposite thread directions, turning the adjusting screw 3 can make the two clamping plates 2 move synchronously in opposite directions to change the distance between the two clamping plates 2. When the adjusting screw is turned... 3. This brings the two clamping plates 2 closer together and clamps the upper rail plate of the rail. At this time, the support is in the working state of positioning support. The positioning support frame provides support. Each side of the support is equipped with a positioning support frame, which consists of a pair of inclined legs 11. The upper ends of the pair of inclined legs 11 on each side are welded together to the end of the suspension beam 1, and the lower ends of the pair of inclined legs 11 are far apart from each other, so that the positioning support frame is in the shape of an "eight". This allows the entire device to stably support the rail, prevent the rail from overturning, and ensure that the bridge erecting machine will not be at risk of tipping over.

[0042] Furthermore, the lower end of the clamping plate 2 is provided with a slot 21 facing the rail, and the slot 21 corresponds to the side of the upper rail plate of the rail. When the clamping plate 2 clamps the rail, the slot 21 fits into the side of the upper rail plate of the rail, so that the rail will not tip over and is more stable.

[0043] Referring to Figures 2, 4, and 5, a push rod 4 extends laterally on the side of each of the two clamping plates 2 that are far apart from each other. The end face of the push rod 4 is inclined upwards. The aforementioned movable support frame consists of a support plate 8, a lifting rod 5, and a wheel frame 9. The support plate 8 is horizontally positioned between two inclined legs on the same side, making the support structure more stable. The lifting rod 5 is upright in the center of the support plate 8. To prevent the lifting rod 5 from rotating, it is designed to be rectangular, and the upper end face of the lifting rod 5 is inclined towards the clamping plate 2. A ring-shaped limiting plate 6 protrudes radially from the upper end of the lifting rod 5. The limiting plate 6 is located above the support plate 8. A spring 7 is provided between the limiting plate 6 and the support plate 8. The spring 7 is sleeved on the outside of the lifting rod 5. The top center of the wheel frame 9 is welded to the lower end of the lifting rod 5. The overall structure of the wheel frame 9 is an inverted U-shape. At least two rollers 10 are provided in the U-shaped space of the wheel frame 9 to maintain balance.

[0044] When disassembling this device from the rail, first turn the adjusting screw 3 to move the two clamping plates 2 away from each other to detach them from the rail. During this process, manually control the two clamping plates 2 to be in the center of the suspension beam 1. As the two clamping plates 2 move away from each other, the ends of the pushing rods 4 on both sides simultaneously press the upper ends of the lifting rods 5 on both sides. That is, the ends of the pushing rods 4 will gradually press the lifting rods 5 down along the upper inclined surface of the lifting rods 5, so that the rollers 10 at the lower end of the lifting rods 5 slowly contact the ground and lift the inclined support legs 11 upward, thus achieving the mobile support mode. In order to facilitate the movement of this device, a rope can be used to pull the entire device to move it on the ground. The operation is simple and achieves the effect of being easy to carry and use. In this state, the upper end of the lifting rod 5 rests against the bottom of the end of the pushing rod 4.

[0045] Because the bridge erecting machine uses sections of steel rails during high-speed railway bridge construction, it needs to move forward a certain distance after each beam erection. Correspondingly, the bridge erecting machine's track must also move accordingly to facilitate the machine's movement for the next beam erection. When the rails move to a new position, this device is still needed to stabilize them. As the bridge erecting machine's track moves, this device also needs to move to the next work location. Therefore, it can be pulled by ropes and moved towards the rails under the drive of the mobile support frame. This facilitates manual labor, and when close to the rails, it can also move along the rails to reach the designated position for the next positioning and support work.

[0046] Correspondingly, when using the device to securely support the rails, first move the device to the designated position, then turn the adjusting screw 3 to make the two clamping plates 2 move towards both sides of the rails simultaneously, while driving the pushing rod 4. Gradually, as the squeezing of the pushing rod 4 is released, the upper end of the lifting rod 5 moves upward with the reaction force of the limiting plate 6 and the spring 7, thereby causing the lower end of the lifting rod 5 to drive the roller 10 away from the ground until the spring 7 is in a stable state. At the same time, the inclined support leg 11 naturally contacts the ground to position and support the entire device. At this time, the two clamping plates 2 just clamp the upper rail plate of the rail, giving the rail a more stable support force, so that the rail will not tilt under force, avoiding the overturning of the bridge erecting machine. It should be noted that when the reaction force of the spring 7 is completely released, the bottom of the upper inclined surface of the lifting rod 5 corresponds to the bottom of the inclined surface of the end of the pushing rod 4.

[0047] The simple anti-tipping device for the traveling rail of the bridge erecting machine provided in this embodiment ensures the stability of the rail when it is under stress by the cooperation between the clamp and the support, preventing it from overturning and thus protecting the bridge erecting machine from the risk of overturning. In addition, the device can be moved by the movable support frames on both sides, without the need for manual movement, achieving the effect of being easy to carry and use, and the operation is extremely simple.

[0048] 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.
