Description

Technical Field

[0001] This utility model relates to the field of bridges, and in particular to a propulsion device for bridge assembly. Background Technology

[0002] Bridges are elevated passageways built across natural or man-made obstacles, commonly used in transportation, urban construction, aqueducts, cable carriers, and strategic applications. Bridge assembly propulsion devices can safely, accurately, and efficiently push massive bridge segments to their designated locations for installation without disrupting traffic or the environment below.

[0003] However, in existing bridge assembly propulsion devices, the bridge angle is prone to directional deviation during propulsion. If not corrected in time, this will lead to misalignment of the bridge axis and misalignment during splicing. In addition, existing bridge assembly propulsion devices require long-term, uninterrupted manual monitoring to identify deviations, resulting in high labor intensity for workers and a high risk of oversight due to fatigue.

[0004] Therefore, this application provides a propulsion device for bridge assembly to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bridge assembly propulsion device that can detect in real time whether the bridge angle has shifted, and can quickly adjust the bridge if it has shifted.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A bridge assembly propulsion device includes a base, two third supports, and four first supports. The upper surface of the base has support cavities at both its front and rear ends. A support column is fixedly installed on the bottom surface of each of the two support cavities. A sliding block is slidably installed inside each of the two support cavities. A first groove is formed on both sides of the outer wall of each of the two sliding blocks. First rollers are rotatably mounted on the inner walls of the front and rear ends of each of the four first grooves via bearings. Holes are formed on the upper surface of each of the two sliding blocks. A second support is fixedly installed on the upper surface of the base. A second groove is formed on both sides of the outer wall of the second support. Support plates are slidably installed on the upper surfaces of the two third supports. Support blocks are fixedly installed at two corners on one side of the upper surface of the base near the outer wall. Multiple infrared sensors are fixedly connected to the upper surface of the other side of the outer wall of the two support blocks and the front and rear ends of the upper surface of the base. Second rollers are rotatably mounted on the inner walls of both sides of each of the four first supports via bearings.

[0007] Furthermore, two third hydraulic rods are fixedly installed on the bottom surface of each of the two supporting cavities, and the lower end faces of the two sliding blocks are respectively fixedly connected to the sliding ends of two adjacent third hydraulic rods among the four third hydraulic rods. The two pillars are respectively slidably installed inside the two holes.

[0008] Furthermore, a motor is fixedly installed on the upper end face of one side of the outer wall of each of the four first brackets, and the output ends of the four motors pass through one side of the outer wall of the four first brackets and are fixedly connected to the four second rollers.

[0009] Furthermore, a first hydraulic rod is fixedly installed at each of the four corners on the upper surface of the base, and the lower surfaces of the four first brackets are respectively fixedly connected to the sliding ends of the four first hydraulic rods.

[0010] Furthermore, two second hydraulic rods are fixedly installed on the inner walls of the two second grooves, and the two second hydraulic rods are respectively fixedly connected to the outer walls of the two third supports.

[0011] Furthermore, two fourth hydraulic rods are fixedly installed on the inner bottom surfaces of the two third supports, and the lower end surfaces of the two support plates are respectively fixedly connected to the output ends of the two adjacent fourth hydraulic rods.

[0012] Furthermore, each of the two third supports has multiple third rollers rotatably mounted on its lower end face via bearings.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 — Figure 4 This utility model provides an embodiment of a bridge assembly propulsion device, comprising a base 1, two third supports 16, and four first supports 10. Support cavities 2 are formed on the upper surface of the base 1 near the front and rear ends. Support columns 3 are fixedly installed on the bottom surfaces of the two support cavities 2. Sliding blocks 4 are slidably installed inside the two support cavities 2. First grooves 5 are formed on both sides of the outer walls of the two sliding blocks 4. First rollers 6 are rotatably installed on the inner walls of the front and rear ends of the four first grooves 5 via bearings. Holes 19 are formed on the upper surface of the two sliding blocks 4. Second supports 13 are fixedly installed on the upper surface of the base 1. Second grooves 14 are formed on both sides of the outer walls of the second supports 13. Support plates 17 are slidably installed on the upper surfaces of the two third supports 16. Support blocks 7 are fixedly installed at two corners on one side of the upper surface of the base 1 near the outer wall. Multiple infrared sensors 8 are fixedly connected to the upper surface of the other side of the outer wall of the two support blocks 7 and the front and rear ends of the upper surface of the base 1 near the front and rear ends. Second rollers 11 are rotatably installed on both sides of the inner walls of the four first supports 10 via bearings.

[0019] Specifically, when using this device, multiple units are first placed sequentially on the bridge deck. The two second hydraulic rods 15 at the top of each unit are adjusted so that one is extended and the other is retracted. The bridge is then placed on top of the device and supported by two pillars 3, a second bracket 13, and two support plates 17. Simultaneously, multiple infrared sensors 8 are activated. When movement is required, four third hydraulic rods 18 are activated to drive two sliding blocks 4 upwards, supporting the bridge via four first rollers 6. Simultaneously, four fourth hydraulic rods 20 are activated to support the bridge. The extended second hydraulic rods 15 are retracted, and the retracted second hydraulic rods 15 are extended, moving the bridge towards the side requiring splicing. During movement, any shift in the bridge's angle can be detected by the multiple infrared sensors 8, and the integrated control panel will alert the operator. The operator can then deactivate the four third hydraulic rods 18 and four fourth hydraulic rods 20, stopping the support provided by the two support plates 17 and the four first rollers 6. Simultaneously, four first hydraulic rods 9 are activated to drive four second rollers 11 to support the bridge. Then, four motors 12 are activated to drive the four second rollers 11 to rotate, thereby rotating the bridge and adjusting the angle.

[0020] Reference Figure 1 — Figure 3 The upper surface of the base 1 has support cavities 2 at both the front and rear ends. The bottom surface of each of the two support cavities 2 is fixedly provided with a support column 3. The two support cavities 2 are slidably provided with sliding blocks 4. The outer walls of the two sliding blocks 4 are provided with first grooves 5 on both sides. The inner walls of the front and rear ends of the four first grooves 5 are provided with first rollers 6 through bearings. The upper surface of each of the two sliding blocks 4 has holes 19. The upper surface of the base 1 is fixedly provided with a second bracket 13. The bottom surface of each of the two support cavities 2 is fixedly provided with two third hydraulic rods 18. The lower surface of each of the two sliding blocks 4 is fixedly connected to the sliding ends of two adjacent third hydraulic rods 18. The two support columns 3 are slidably provided inside the two holes 19.

[0021] Specifically, when the bridge is stationary, it is supported by two pillars 3. When movement is required, four third hydraulic rods 18 are activated to drive two sliding blocks 4 upwards, which are supported by four first rollers 6. During movement, the four first rollers 6 reduce friction. Four first grooves 5 provide space for the four first rollers 6. Two holes 19 provide sliding space for the two pillars 3 and also restrict their sliding direction.

[0022] Reference Figure 1 , Figure 2At the two corners of the upper surface of the base 1 near the outer wall, there are two fixed support blocks 7. On the other side of the outer wall of the two support blocks 7, near the upper end and the front and rear ends of the upper surface of the base 1, there are multiple infrared sensors 8. The inner walls of the four first brackets 10 are equipped with second rollers 11 through bearings. At the four corners of the upper surface of the base 1, there are first hydraulic rods 9. The lower surfaces of the four first brackets 10 are fixedly connected to the sliding ends of the four first hydraulic rods 9. The inner bottom surfaces of the two third brackets 16 are each equipped with two fourth hydraulic rods 20. The lower surfaces of the two support plates 17 are respectively fixedly connected to the output ends of the two adjacent fourth hydraulic rods 20. The lower surfaces of the two third brackets 16 are each equipped with multiple third rollers 21 through bearings.

[0023] Specifically, multiple infrared sensors 8 can monitor in real time whether the bridge angle has shifted. Four first hydraulic rods 9 can drive four first supports 10 to rise, which in turn support four second rollers 11, thus supporting the bridge and reducing friction during movement. Four motors 12 can drive the four second rollers 11 to rotate, thereby rotating the bridge to adjust its angle.

[0024] Reference Figure 1 , Figure 2 , Figure 4 The second bracket 13 has a second groove 14 on both sides of its outer wall. The upper surfaces of the two third brackets 16 are slidably provided with support plates 17. The upper surfaces of the outer walls of the four first brackets 10 are fixedly provided with motors 12. The output ends of the four motors 12 pass through the outer walls of the four first brackets 10 and are fixedly connected to the four second rollers 11. The inner walls of the two second grooves 14 are fixedly provided with second hydraulic rods 15. The two second hydraulic rods 15 are fixedly connected to the outer walls of the two third brackets 16 respectively.

[0025] Specifically, four second hydraulic rods 15 can drive two support plates 17 to rise and support the bridge. By retracting and extending two second hydraulic rods 15 respectively, the bridge can be moved to one side. Multiple third rollers 21 can support two third supports 16 respectively, preventing the two third supports 16 from being damaged by long-term friction with the base 1 due to the weight of the bridge.

[0026] Working principle: First, multiple devices are placed sequentially on the bridge deck. Then, the bridge is placed on the devices. Next, four fourth hydraulic rods 20 are activated to drive two support plates 17 to support the bridge. Simultaneously, four third hydraulic rods 18 are activated to drive four first rollers 6 to support the bridge, and two second hydraulic rods 15 are activated to move the bridge. During movement, if the bridge angle shifts, multiple infrared sensors 8 can monitor it and alert the staff. The staff can then shut off the four third hydraulic rods 18 and the two second hydraulic rods 15, activate the four first hydraulic rods 9 to support the bridge via the four second rollers 11, and then activate four motors 12 to drive the four second rollers 11 to rotate the bridge and adjust its angle.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
