Description

Technical Field

[0001] This utility model relates to the field of concrete crack repair technology, and in particular to a concrete crack repair device for water conservancy projects. Background Technology

[0002] Concrete crack repair devices for water conservancy projects are specially designed to repair cracks in concrete structures of water conservancy facilities (such as dams, sluices, and canals). Because concrete is prone to containing air bubbles, the density of the concrete after filling cracks is poor. To ensure the quality of crack repair, it is usually necessary to compact the concrete in the cracks. However, existing concrete crack repair devices for water conservancy projects lack a compaction structure and cannot effectively compact the concrete in the cracks. Additional tools are needed for supplementary compaction, which is time-consuming and labor-intensive, resulting in low crack repair efficiency.

[0003] Therefore, a concrete crack repair device for water conservancy projects has now been developed that can eliminate air bubbles in concrete and compact the concrete, saving manpower and improving the efficiency of crack repair. Utility Model Content

At the lower left of the head 3, the first lead screw 5 is connected to the output shaft of the first motor 4. The first lead screw 5 is rotatably connected to the frame 1. The first slider 6 is threadedly connected to the first lead screw 5. The first slider 6 is slidably connected to the frame 1. The second motor 7 is connected to the front side of the first slider 6. The cleaning roller 8 is connected to the output shaft of the second motor 7. The cleaning roller 8 is rotatably connected to the first slider 6. The frame 1 is also equipped with a repair assembly, which includes a material tank 9, a mixing assembly 10, a water pump 11, a telescopic spray pipe 12, a third motor 13, a second lead screw 14, a second slider 15, and an electric push rod 16. The right side of the frame 1... The material hopper 9 is connected to the upper side, and the mixing assembly 10 is provided on the material hopper 9. The mixing assembly 10 includes a drive motor and a mixing frame. The drive motor is connected to the upper side of the material hopper 9, and the mixing frame is connected to the output shaft of the drive motor. The mixing frame is rotatably connected to the material hopper 9. An observation window is provided on the front side of the material hopper 9 for easy observation of the concrete volume. The water pump 11 is connected to the upper middle part of the vehicle frame 1. The right side of the water pump 11 is connected to the material hopper 9. The telescopic spray pipe 12 is connected to the lower side of the water pump 11. The third motor 13 is connected to the front left side of the vehicle frame 1. The second lead screw 14 is connected to the output shaft of the third motor 13. The second lead screw 14 is connected to the vehicle frame 1. The second slider 15 is threaded onto the second lead screw 14, and the telescopic nozzle 12 passes through the second slider 15. The second slider 15 is slidably connected to the frame 1. The electric push rod 16 is connected to the second slider 15, and the telescopic end of the electric push rod 16 is connected to the telescopic nozzle 12. The repair assembly is equipped with a vibration assembly, which includes a fourth motor 18, a cam 19, and a torsion spring 20.

The torsion spring 20 is connected between the cam 19 and the connecting block.

[0020] When using this invention, firstly, concrete is poured into the hopper 9, and the drive motor in the mixing assembly 10 is started to rotate the mixing frame and mix the concrete. Then, the dual-shaft motor 2 is started to rotate the wheels. The surrounding situation is observed through the upper camera 3, and the vehicle frame 1 is moved to the crack repair position. Then, the first motor 4 is started to rotate the first lead screw 5, causing the first slider 6 to move downwards until the cleaning roller 8 contacts the ground. Then, the second motor 7 is started to rotate the cleaning roller 8, allowing the cleaning roller 8 to clean the crack. After cleaning, the cleaning roller 8 stops rotating and moves upwards to reset. Then, the vehicle frame 1 is moved so that the telescopic nozzle 12 is above the crack. Then, the water pump 11 is started to allow concrete to enter the telescopic nozzle 12 and be sprayed into the crack to repair it. After the concrete fills the crack, the compaction roller 17 can be moved on the crack to further fill it. When the concrete is compacted and smoothed, the location of the crack can be observed through the lower camera 3 during repair. Then, the third motor 13 is activated to drive the second lead screw 14 to rotate, causing the second slider 15 to move back and forth, which in turn drives the telescopic nozzle 12 to move, so as to repair cracks in different locations. When the concrete enters the telescopic nozzle 12, the fourth motor 18 can be activated to drive the cam 19 to rotate, causing the cam 19 to strike the telescopic nozzle 12, making the telescopic nozzle 12 vibrate. After the cam 19 contacts the telescopic nozzle 12, the torsion spring 20 deforms. After the cam 19 disengages from the telescopic nozzle 12, the torsion spring 20 returns to its original position, allowing the cam 19 to reset. When the telescopic nozzle 12 vibrates, the electric push rod 16 can be activated to push the telescopic nozzle 12 downward into the concrete in the crack, thereby eliminating air bubbles in the concrete and compacting the concrete, saving manpower and improving the efficiency of crack repair.
