[0002] A dike breach refers to the process in which the dike of a river or lake breaks due to natural or human factors, the water flows through the defense line, and a large-scale flood is formed. Unlike a reservoir breach, a dike breach mainly threatens the downstream plains, cities and farmland. The key to the successful rescue and plugging of a large dike breach is to throw a large amount of plugging materials (steel mesh gabions, earth and stone materials, special structures, etc.) in a short period of time to prevent the development of water flow, form a breach in a short period of time, and block the breach, thereby expanding the rescue operation area. Therefore, the feeding and throwing equipment need to be automated. The development of automatic control technology for breach entry is the key to achieving high-intensity throwing of the breach, realizing automated control and mechanized construction of pile planting and throwing equipment, and having the ability to cast high-intensity continuous throwing construction for breach plugging. At present, the main methods for repairing breaches are land truck feeding and water stone throwing, but the land operation site is small and the external transportation relies only on narrow dike top roads.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] The present invention provides a Figures 1 - 4 , Figure 8 , Figure 9 The continuous casting and filling device for dike breaches with self-propelling function shown in the figure has dimensions of length × width × height = 5.0 m × 1.5 m × 1.0 m. The bottom crawler track structure 8 is used to carry the material 9 to be cast. The crawler track model is 31.75 mm. An engine with an output power between 150 and 200 kW is selected, which can carry no less than 9 tons of goods to meet the requirements of the casting weight. The structural framework 1 is the basic framework of the device of the present invention, and all other components are installed on the structural framework. The power runner 4 is installed on the left side of the device and drives the driven runner 5 during walking, thereby driving the entire device to walk. In the material transportation mode, the bearing support 2 is retracted. In the feeding mode, the bearing support is placed to enter the feeding process. The lower support runner 6 is used when the device is in the material transportation mode, and the crawler track 8 touches the ground to ensure sufficient friction with the ground. The upper support runner 6 is used to lift and transfer goods during feeding to prevent the crawler track 8 from collapsing.

[0034] The power runner 4 is fixedly installed at the front of the continuous transfer device and is hydraulically driven. The crawler track model is 31.75 mm. An engine with an output power between 150 and 200 kW is selected, which can carry no less than 9 tons of goods to meet the requirements of the casting weight.

The thruster push arm is hinged to the driven wheel connecting bracket 3, and the elastic force of its internally provided spring is used to push the driven wheel connecting bracket 3 outwards, thereby realizing the tensioning of the crawler 8 and preventing the crawler 8 from loosening and falling off.

[0037] The bearing bracket 2 is a steel structure frame installed on the structural frame 1 and is used to control the working state of the equipment to be in the autonomous walking mode or the continuous operation mode respectively. When the bearing bracket 2 is retracted, the equipment is in the material transportation mode; when the bearing bracket 2 is lowered, the equipment is lifted off the ground, and the equipment is in the feeding mode.

[0038] At the breach, in the direction perpendicular to the water flow 12, in cooperation with the pile planting 10, at the back river embankment slope, first the filling of the thrown materials 9 is carried out, and then the material transportation is carried out and transported to the breach for filling. This process is a continuous process, and multiple sets of transfer devices are carried out continuously, one after another for filling materials, transporting materials, and throwing materials. The whole process is high-speed, effective, and uninterrupted, with high efficiency and a large amount of material transportation. This equipment can throw 600 cubic meters of stones per hour, and a 20-cubic-meter stone dump truck can throw 300 cubic meters of stones per hour. By comparison, this developed equipment has the advantages of a large amount of material transportation, high speed, automation, high efficiency, etc., and has the ability to carry out high-strength continuous throwing construction for breach blocking;

[0039] A runner bracket 3 is arranged between two adjacent throwing devices;

One side of one of the second connection blocks 16 is movably connected to a rotation center block 18, and one side of the other second connection block 16 is movably connected to a second magnet 17. The second magnet 17 is adsorbed and connected to the rotation center block 18. The other connection assembly 15 includes two first connection blocks 151. Both of the first connection blocks 151 are movably connected to a first magnet 153 through a rotating shaft, and a first torsion spring 152 is connected to the rotating shaft movably connected between the first connection block 151 and the first magnet 153. An intermediate block 155 is adsorbed between the two first magnets 153. A threaded rod 157 and a secondary rod 158 are movably connected inside the intermediate block 155, and the threaded rod 157 and the secondary rod 158 are respectively connected to the inner wall of the intermediate block 155 through two second torsion springs 154;

[0042] At least one first metal wire is fixedly connected to one side of one of the first magnets 153 close to the intermediate block 155, and the first metal wire is wound and connected to the secondary rod 158;

[0043] Another magnet - 153 is provided with a second metal wire 156 on one side close to the middle block 155, and one end of the second metal wire 156 is wound and connected to the threaded rod 157. A nut is threadedly connected to the threaded rod 157, and one end of the rotating cylinder 14 is movably connected to the nut through a bearing. The other end of the rotating cylinder 14 contacts the surface of the rotating center block 18.

[0044] Embodiment 2: On the basis of Embodiment 1, through the setting of the compensation component 13, when multiple throwing devices need to perform arc transportation, in order to avoid the bending angle between adjacent two throwing devices being too large and affecting the continuity of the entire transportation and the integrity of the transportation state. At this time, when the staff determines the bending angle according to the on-site situation, the compensation component 13 can be installed between the corresponding throwing devices in advance. Taking the connecting block two 16, the rotating center block 18 and the magnet two 17 as the rotation center, and taking the middle block 155 as the arc pulling radius, when forming an arc between the two throwing devices, the second metal wire 156 is pulled to drive the threaded rod 157 to rotate. When the threaded rod 157 rotates, it drives the nut and the rotating cylinder 14 to move upward until it moves flush with the transportation surface of the throwing device, so as to fill the arc space formed by adjacent two throwing devices with the rotating cylinder 14, supplement the integrity of the entire transportation route, and prevent the influence on the material transportation state caused by the gap generated by the arc bending.
