[0022] Specific implementation,

[0023] Refer to Figure 1 And Figure 2It can be known that when the device for repairing bridge expansion joint is used, it is usually necessary to disassemble it, so that it is more inconvenient to repair the deformed bridge expansion joint. First, the fan 7 is started, so that the fan 7 can generate suction, and the impurities at the repair site are sucked through the suction pipe 9. Then the water in the water tank 2 is added through the water outlet 4, so that the reference surface can be infiltrated to improve the adhesion between the new and old materials. Then according to the specific circumstances, template support or reinforcement steel mesh skeleton and other measures are taken. Finally, the repair material is poured. The repair material is fast-hardening concrete, and the 2-hour strength can reach 30MPa, and the 28d strength can reach more than 60MPa, so that the traffic can be quickly restored to ensure the repair effect, so that the deformed expansion joint can be repaired without disassembly. At the same time, the driving motor 12 can be started, so that the driving motor 12 can rotate the first rotating rod 13 connected to the output end, so that the first rotating rod 13 can rotate the belt pulley set 15 connected when rotating, so that the belt pulley set 15 can synchronously rotate the second rotating rod 14 connected when rotating. At the same time, the driving motor 12 can rotate the bevel gear set 16 connected on one side when rotating, so that the bevel gear set 16 can rotate the rotating rod 17 connected when rotating, so that the rotating rod 17 can rotate the mixing rod 18 connected on both sides when rotating, so that the mixing rod 18 can mix the repair material in the mixing frame 10 when rotating. And the second rotating rod 14 can rotate the turnover plate 19 when rotating, so that the material at the bottom can be turned over to avoid accumulation at the bottom, so that the rotating mixing rod 18 can avoid condensation when waiting for pouring, so that it is more convenient to repair the bridge expansion joint.

[0024] One end of the collection frame 5 is provided with a vertical plate 20, the inside of the vertical plate 20 is provided with a rotating gear 21, one end of the rotating gear 21 is provided with a rotating shaft 22 connected through a bearing, one end of the rotating shaft 22 is connected with a limiting plate 23, one end of the rotating shaft 22 close to the rotating gear 21 is provided with a torsional spring 24 connected with the vertical plate 20, one side of the rotating gear 21 is provided with a limiting gear ring 25, the surface of the limiting gear ring 25 is connected with the limiting spring 26 between the vertical plate 20.

[0025] In specific implementation,

[0026] Referring to Figures 1-4It can be known that when the device for repairing bridge expansion joints is in use, the protective door is usually opened, and the collected impurities are easy to overflow, so that the device for repairing bridge expansion joints is inconvenient to use. The limiting ring 25 can be pulled to extrude the limiting spring 26 connected on one side when the limiting ring 25 moves, and the limiting ring 25 can be separated from the rotating gear 21 when the limiting ring 25 moves, so that the torsional spring 24 can be lost, and then the torsional spring 24 can be reset, so that the rotating shaft 22 connected with the torsional spring 24 can be rotated, and the limiting plate 23 connected at one end of the rotating shaft 22 can be rotated, so that the limiting plate 23 can limit the cabinet door 6 after being rotated, thereby avoiding that the cabinet door 6 is opened due to vibration during use. Then, the limiting ring 25 is loosened, so that the limiting ring 25 can be locked with the rotating gear 21 again after the limiting spring 26 is reset, so that the device for repairing bridge expansion joints can have a better limiting effect when the impurities are sucked.

[0027] In summary, the main function of the bridge expansion joint is to adjust the expansion deformation of the bridge caused by various factors, to ensure the stability of the bridge structure and the safety of driving. However, most of the bridge expansion joints will be aged or deformed after a long period of use, and even broken. Therefore, it is necessary to repair the bridge expansion joint. First, the fan 7 is started to generate suction, and the impurities at the repair site are sucked through the suction pipe 9. Then, the water in the water tank 2 is added through the water outlet 4 to soak the reference surface, so as to improve the adhesion between the new and old materials. Then, according to the specific situation, measures such as template support or reinforcement of steel mesh skeleton are taken. Finally, the repair material is poured. Using fast-hardening and early-strength concrete to repair the expansion joint can improve the strength and durability of the repair layer, effectively ensure the safe operation of the bridge, and reduce the traffic interruption time during rapid hardening construction, so as to ensure the normal traffic of the road and the repair effect. When repairing the deformed expansion joint, it is not necessary to demolish, so that the repair of the bridge expansion joint is more convenient. Therefore, the development of the low-carbon fast-hardening and early-strength repair material for bridge expansion joints and the application project can improve the construction efficiency, enhance the repair effect, and ensure the safety of the bridge and the traffic operation.
