[0002] With the development of cities, the scale of municipal road construction is getting larger and larger, and the construction of municipal bridges is also becoming more and more. After the roads and bridges are laid, they will gradually become fragile after being damaged by high temperature, severe cold and rain for a long time during the process of being put into use. In addition, when they are subjected to large loads that exceed their carrying capacity, cracks will appear, causing cracks in roads and bridges. For the sake of road quality and beauty, we need to repair the cracks, which requires the use of crack repair devices.

[0027] The adjusting structure 8 includes a second motor 81, and the second motor 81 is fixedly connected to the outer surface of one side of the movable bottom plate 1, and the first screw rod 82 is fixedly connected to the output end of the second motor 81, and the outer surface of the first screw rod 82 is threadedly connected to the moving block 83, and the bottom surface of the moving block 83 is installed with an electric telescopic rod 84, and the lower end of the electric telescopic rod 84 is fixedly connected to the repair tube 85. When the second motor 81 is started, this design makes the first screw rod 82 rotate inside the observation slot 7, and makes the moving block 83 move laterally on the outer surface of the first screw rod 82. At this time, starting the electric telescopic rod 84 can drive the repair tube 85 to move up and down, so that the position and depth of the repair tube 85 can be adjusted when the crack of the device is repaired, which improves the repair effect to a certain extent;

When the device is in use, this design can observe the position of the device repair through the observation groove 7 and make adjustments in time, which improves the practicality of the device to a certain extent. When the moving block 83 moves, the rectangular slider moves synchronously inside the rectangular chute, so that the moving block 83 can be more stable when moving, avoiding the deflection of the moving block 83.

[0029] A stirring rod is fixedly connected to the output end of the first motor 5, and the stirring rod is arranged inside the storage barrel 3.

[0031] Embodiment 2

[0032] like Figure 5-Figure 6 As shown, based on the same concept as the above embodiment, this embodiment further proposes: a flattening structure 9, the flattening structure 9 includes a second screw rod 91, and the second screw rod 91 is connected to the inside of the bottom surface of one end of the movable bottom plate 1 with a bearing, and the flattening structure 9 also includes a movable plate 92, and the movable plate 92 is provided with two groups, and the two groups of movable plates 92 are respectively threadedly connected to the outer surfaces of the two ends of the second screw rod 91, and a movable groove is provided inside the bottom surface of one end of the movable bottom plate 1, and the outer size of the upper end of the movable plate 92 is adapted to the inner size of the movable groove. This design enables the movable plate 92 to move synchronously in the movable groove when the outer surface of the second screw rod 91 moves, thereby making the movable plate 92 more stable when moving, and avoiding the deflection of the movable plate 92;

[0033] An insertion groove 93 is provided inside the lower end surface of the movable plate 92, and rectangular connecting grooves are provided on the inner wall surfaces on both sides of the insertion groove 93, and a connecting rod 94 is fixedly connected inside the rectangular connecting groove, and a spring 95 and a lower pressure plate 96 are sleeved on the outer surface of the connecting rod 94, and an insertion rod 97 is inserted inside the insertion groove 93, and one end of the insertion rod 97 is fixedly connected to a flattening roller 98, and the outer surface of the insertion rod 97 fits with the inner wall surface of the lower end of the insertion groove 93 and the inner wall surface of the lower end of the lower pressure plate 96. This design allows the insertion rod 97 to rotate at the middle position between the insertion groove 93 and the lower pressure plate 96. When the inner side surfaces of the two groups of movable plates 92 fit the outer surfaces at both ends of the flattening roller 98, the position of the flattening roller 98 can be positioned, and when the inner side surfaces of the two groups of movable plates 92 are away from the outer surfaces at both ends of the flattening roller 98, the flattening roller 98 can be disassembled;

[0034] The two sets of moving plates 92 are respectively threadedly connected to the outer surface of the second screw rod 91, and the internal threads are opposite to each other. This design allows the two sets of moving plates 92 to move outward or inward synchronously on the outer surfaces of both ends of the second screw rod 91 when the second screw rod 91 is rotated;

[0035] Rectangular connecting blocks are provided on the outer surfaces of both sides of the lower pressure plate 96, and the outer dimensions of the rectangular connecting blocks are adapted to the inner dimensions of the rectangular connecting grooves. The two ends of the spring 95 respectively abut against the upper end surface of the rectangular connecting blocks and the top surface inside the rectangular connecting grooves. The bottom surface of the flattening roller 98 is on the same horizontal line as the bottom surface of the universal wheel. The road bridge surface may have a small slope. At this time, the lower pressure plate 96 can be driven to move on the outer surface of the connecting rod 94, and the lower pressure plate 96 is supported by the elasticity of the spring 95 itself, so that the lower pressure plate 96 can reset itself, and the insertion rod 97 can be driven by the lower pressure plate 96 to reset itself, so that the outer surface of the flattening roller 98 is always in contact with the ground to flatten the repaired cracks.

[0036] Working principle: When the equipment is used, firstly, the repair material is injected into the storage barrel 3 through the feed hopper 4, then a set of insertion rods 97 are inserted into a set of insertion slots 93, and the second screw rod 91 is rotated, so that the two sets of moving plates 92 can be moved inward synchronously, and then another set of insertion rods 97 are inserted into another set of insertion slots 93. When the inner surfaces of the two sets of moving plates 92 are attached to the outer surfaces of both ends of the flattening roller 98, the installation of the flattening roller 98 is completed, and then the moving bottom plate 1 is pushed to drive the equipment to move, and the water pump, the first motor 5, and the second motor 81 are supplied by the battery 2. The power source of the electric telescopic rod 84 is used to start the first motor 5 so that the stirring rod rotates to stir the repair material, and then the second motor 81 is started to rotate the first screw rod 82. At this time, the moving block 83 moves laterally on the outer surface of the first screw rod 82, and the position of the repair tube 85 is observed through the observation slot 7. The electric telescopic rod 84 is started so that the electric telescopic rod 84 drives the repair tube 85 to move up and down, and the position of the repair tube 85 is aligned with the position of the crack, and then the water pump is started to transport the repair material to the inside of the repair tube 85 through the discharge pipe 6, thereby repairing the gap through the adjustment structure 8;

[0037] When the equipment is in use, the movable base plate 1 is pulled to move, and the flattening roller 98 rolls on the ground, and the surface of the road bridge is flattened by the flattening roller 98, so that the flatness of the road bridge surface is maintained by the flattening structure 9. When the road surface has a certain slope, the insertion rod 97 can move inside the insertion groove 93, and the lower pressure plate 96 is supported by the elasticity of the spring 95 itself, so that the lower pressure plate 96 can move on the outer surface of the connecting rod 94, and the outer surface of the flattening roller 98 is always in contact with the ground. The above is the entire working principle of the utility model.
