[0002] Steel sheet piles are a kind of protective structure commonly used in civil engineering, mainly used for supporting or isolating soil bodies to prevent soil erosion and soil loss, or as part of projects such as water conservancy, ports, and infrastructure. Steel sheet piles are usually made of steel, with strong bending strength and corrosion resistance, and are suitable for humid environments such as the ocean and rivers. A steel sheet pile driving device is a device used to drive steel sheet piles into the ground or underwater. These devices drive or press the steel sheet piles into the soil mechanically to form a stable supporting structure.

[0003] In the prior art, the current steel sheet pile driving device generally uses a crawler excavator equipped with clamping jaws to clamp the steel sheet piles and dock them with other steel sheet piles, and then uses a separate knocking device or pressing device to press the steel sheet piles into the ground. However, using two large devices not only occupies the construction site, but also has high construction costs and low efficiency, and cannot meet the construction requirements. Therefore, we propose a driving device for steel sheet piles and a driving method thereof to solve the above problems. Summary of the Invention

[0035] The present invention also proposes a driving method for a driving device of a steel sheet pile, including the following steps: S1: First, drive the lifting arm 1 of the crawler excavator to move through the excavator. Then, when the two rotating plates 12 are sleeved on the steel sheet pile body 18, starting the two first hydraulic cylinders 13 can drive the two rotating plates 12 to rotate and clamp and fix the steel sheet pile body 18. At this time, then hoist the steel sheet pile body 18 to the construction position through the crawler excavator lifting arm 1; S2: Then start the motor 5, which can drive the first gear 6, the second gear 7, the rotating shaft 4, the support plate 10, the two rotating plates 12 and the steel sheet pile body 18 to rotate. At this time, the steel sheet pile body 18 can be adjusted to be perpendicular to the ground; S3: At this time, starting the fourth hydraulic cylinder 23 can drive the fifth hydraulic cylinder 28 and the pressing block 29 to move to the left and be located above the steel sheet pile body 18. Then, starting the third hydraulic cylinder 22 drives the fourth hydraulic cylinder 23, the slider 24, the fifth hydraulic cylinder 28 and the pressing block 29 to move downward so that the pressing block 29 is at an appropriate distance from the top of the steel sheet pile body 18; S4: Finally, start the second hydraulic cylinder 14 to drive the two clamping plates 15 to move away from each other. At this time, only the four limiting rollers 20 limit the steel sheet pile body 18. Then, starting the fifth hydraulic cylinder 28 can drive the pressing block 29 to move up and down reciprocally to hammer and drive the steel sheet pile body 18 downward, so as to realize the installation between the steel sheet pile body 18 and the ground or adjacent steel sheet pile bodies 18.

[0036] It should be noted that: For the specific models of the crawler excavator boom 1, the motor 5, the first hydraulic cylinder 13, the second hydraulic cylinder 14, the third hydraulic cylinder 22, the fourth hydraulic cylinder 23 and the fifth hydraulic cylinder 28, those skilled in the relevant art can select them by themselves. Moreover, the above-mentioned crawler excavator boom 1, the motor 5, the first hydraulic cylinder 13, the second hydraulic cylinder 14, the third hydraulic cylinder 22, the fourth hydraulic cylinder 23 and the fifth hydraulic cylinder 28 all belong to the prior art, and this solution will not be elaborated here.

[0037] Working principle: When in use, first connect the power supply to the crawler excavator lifting arm 1, motor 5, first hydraulic cylinder 13, second hydraulic cylinder 14, third hydraulic cylinder 22, fourth hydraulic cylinder 23 and fifth hydraulic cylinder 28. Then, drive the crawler excavator lifting arm 1 to move through the excavator. When the two rotating plates 12 are sleeved on the steel sheet pile body 18, start the two first hydraulic cylinders 13, which can drive the two rotating plates 12 to rotate and clamp and fix the steel sheet pile body 18. At this time, lift the steel sheet pile body 18 to the construction position through the crawler excavator lifting arm 1. Then start the motor 5, which can drive the first gear 6 to rotate. At this time, the first gear 6 can drive the second gear 7 and the rotating shaft 4 to rotate. At the same time, the rotating shaft 4 can drive the support plate 10, the two rotating plates 12 and the steel sheet pile body 18 to rotate. At this time, the steel sheet pile body 18 can be adjusted to be perpendicular to the ground, so as to facilitate the insertion and installation between the steel sheet pile body 18 and the ground or adjacent steel sheet pile bodies 18. Then, when the docking between the steel sheet pile body 18 and the ground or adjacent steel sheet pile bodies 18 is completed, start the fourth hydraulic cylinder 23, which can drive the fifth hydraulic cylinder 28 and the pressing block 29 to move to the left and be located above the steel sheet pile body 18. At this time, start the third hydraulic cylinder 22 to drive the fourth hydraulic cylinder 23, the slider 24, the fifth hydraulic cylinder 28 and the pressing block 29 to move downward so that the pressing block 29 is at an appropriate distance from the top of the steel sheet pile body 18. Then start the fifth hydraulic cylinder 28, which can drive the pressing block 29 to move downward reciprocally and hammer the steel sheet pile body 18 downward to realize the installation between the steel sheet pile body 18 and the ground or adjacent steel sheet pile bodies 18. Here, by starting the second hydraulic cylinder 14, the two clamping plates 15 can be driven to approach each other and cooperate with the two rotating plates 12 to clamp the steel sheet pile body 18. And when the second hydraulic cylinder 14 drives the two clamping plates 15 to move away from each other, at this time, only the four limiting rollers 20 limit the steel sheet pile body 18. Therefore, the steel sheet pile body 18 can move downward under stable limiting, so as to facilitate driving the steel sheet pile body 18 downward. And in this way, the efficient insertion and installation between the steel sheet pile body 18 and the ground or adjacent steel sheet pile bodies 18 is realized. It can cooperate with the crawler excavator to realize the lifting, position adjustment, limiting and automatic hammering of the steel sheet pile body 18. The integrated design is efficient and convenient, greatly improving the construction efficiency and having strong practicability.
