Description

Technical Field

[0001] The present invention relates to the technical field of steel truss bridge transportation, and particularly to a rapid transportation device for the whole steel truss bridge. Background Art

[0002] A steel truss bridge is a structural system between a beam and an arch. It is a structure in which the upper beam structure subjected to bending is integrally combined with the lower column subjected to compression. This bridge type is a commonly used selection scheme in the urban construction of our country and is widely used in domestic highway overpasses. At present, when a steel truss bridge is damaged, it is mostly hoisted to the top of a freight car by a cable and transported back to the factory by the freight car for repair. However, when the road surface is relatively narrow, it is impossible to use a cable for hoisting, and the installation cost of the cable hoist is high, and the construction technical difficulty is great. Workers usually use jacks to lift both ends of the steel truss bridge and move it to the upper end of the freight car to transport the steel truss bridge.

[0003] In a comparative document of a rapid transportation device for the whole steel truss bridge proposed in the publication number CN113246834A, it is specifically proposed that "including a carriage, a rotating device is fixedly installed at the middle position of the top of the carriage, a limiting device is movably connected to the top of the rotating device, a steel truss bridge base is arranged at the top of the limiting device, and covering devices are arranged at the top positions of the left and right ends of the carriage".

[0004] The above-mentioned comparative document also has the following defects: when using a vehicle for transportation and transfer, there is a lack of limiting measures for the steel truss bridge, and when turning, a separate power source needs to be equipped, which increases the cost of the equipment, and there is a lack of support measures after turning, and the safety is poor. For this reason, we propose a rapid transportation device for the whole steel truss bridge. Summary of the Invention

The placement plate 6 can be horizontally limited by the limiting component.

[0032] As Figure 6 shown, the moving component 2 includes two vertical plates fixedly connected to the bottom of the vehicle plate 1. A horizontal shaft is rotatably arranged between the two vertical plates. Two moving wheels are fixedly sleeved on the outside of the horizontal shaft. The first bevel gear 4 is fixedly sleeved on the outside of the horizontal shaft. A servo motor 3 is fixedly connected to the vertical plate, and the output shaft of the servo motor 3 is fixedly connected to the horizontal shaft. The servo motor 3 drives the horizontal shaft to rotate, the horizontal shaft drives the moving wheels to rotate, and the moving wheels drive the whole device to move forward.

[0033] As Figure 3 shown, the transmission component includes a second push rod motor 16 fixedly sleeved inside the vehicle plate 1. The output shaft of the second push rod motor 16 is fixedly connected to a lifting plate 17. A bearing 18 is fixedly connected to one side of the lifting plate 17. A transmission shaft 19 is fixedly sleeved inside the bearing 18. A second bevel gear 20 is fixedly connected to the bottom end of the transmission shaft 19, and the second bevel gear 20 meshes with the first bevel gear 4 for transmission. A plug connector 21 is fixedly connected to the top end of the transmission shaft 19. The second push rod motor 16 drives the lifting plate 17 to lift, and the lifting plate 17 drives the transmission shaft 19 and the second bevel gear 20 to lift and transmit. When the plug connector 21 is inserted into the support seat 5, the teeth on the first bevel gear 4 and the second bevel gear 20 are still in meshing state to maintain normal transmission.

[0034] As Figure 3 shown, a cross-shaped insertion slot is opened at the bottom of the support seat 5. The cross section of the plug connector 21 is also a cross-shaped structure, and the plug connector 21 matches the insertion slot.

[0035] As Figure 4 shown, the support component includes a positioning shaft 7 arranged inside the placement plate 6. A ring is movably sleeved on the outside of the positioning shaft 7. A hydraulic cylinder 8 is fixedly connected to one side of the ring. The output shaft of the hydraulic cylinder 8 is fixedly connected to a support plate 9.

[0036] As Figure 4 shown, U-shaped grooves are opened on both sides of the placement plate 6. The positioning shaft 7 is fixedly arranged in the U-shaped grooves.

[0037] As Figure 5As shown in the figure, the limit component includes two positioning seats 12 fixedly connected to the top of the vehicle board 1. A rotating shaft 13 is movably sleeved inside the positioning seat 12. Limit plates 14 are fixedly connected to both ends of the rotating shaft 13. A gear 15 is fixedly sleeved outside the rotating shaft 13. An adjusting component is arranged above the gear 15.

[0038] As Figure 1 shown in the figure, the adjusting component includes a first push rod motor 10 fixedly connected to the top of the vehicle board 1. A rack 11 is fixedly connected to the output shaft of the first push rod motor 10. The rack 11 is in meshing transmission with the gear 15. The first push rod motor 10 drives the rack 11 to move. The rack 11 can drive the gear 15 to rotate, and then drive the rotating shaft 13 to rotate.

[0041] Working principle: First, move the whole device to the bottom of the integral steel truss bridge. Lower the integral steel truss bridge onto the placing plate 6 through a jack. At this time, the servo motor 3 drives the horizontal shaft to rotate, and the horizontal shaft drives the moving wheels to rotate. The moving wheels drive the whole device to move. The erected limit plates 14 can limit the placing plate 6 and the integral steel truss bridge. When the placing plate 6 needs to be turned, at this time, the first push rod motor 10 drives the rack 11 to move. The rack 11 drives the gear 15 to rotate. The gear 15 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the limit plates 14 to rotate horizontally, thus releasing the limit on the placing plate 6. The second push rod motor 16 drives the lifting plate 17 to move upward, so that the transmission shaft 19 drives the plug connector 21 to insert into the support seat 5. At this time, the teeth on the first bevel gear 4 and the second bevel gear 20 are still in meshing state to maintain normal transmission. In this way, the servo motor 3 drives the horizontal shaft to rotate. The horizontal shaft drives the transmission shaft 19 to rotate through the first bevel gear 4 and the second bevel gear 20. The transmission shaft 19 drives the support seat 5 to rotate. The support seat 5 drives the placing plate 6 to turn. After the placing plate 6 turns, at this time, the hydraulic cylinder 8 vertically drops down. In this way, the hydraulic cylinder 8 drives the support plate 9 to land and support, which is beneficial to the safety of the placing plate 6.
