Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides a technical solution for a small pile driver: a small pile driver includes a base 1, and a plurality of floats 2 for supporting floating on the water are evenly distributed on the bottom of the base 1. The floats 2 are high-density foam boxes or pontoons, wherein the base 1 is composed of a combination of steel pipes, channel steels, pipe fittings, etc., and the floats 2 and the base 1 can be connected and fixed by lead wires and large ropes, but are not limited to, to form a floating ship as a whole.

[0021] A guardrail 3 is welded at the upper edge of the base 1, and a protective net 4 is fixed on the guardrail 3. The guardrail 3 is installed around the base 1 to play a role in safety protection. A winch 5 and a generator 6 are installed on one side of the upper end of the base 1. A winch base 51 and a generator mounting seat 61 are provided on the upper surface of the base 1 corresponding to the winch 5 and the generator 6. The winch 5 and the generator 6 are fixed to the base 1 by the winch base 51 and the generator mounting seat 61 respectively, and the generator 6 generates electricity to provide power for the winch 5. The winch 5 is used to drive the steel wire traction rope 9 to be wound or released, thereby driving the iron lump 11 to rise or fall;

[0022] A truss 8 is installed on the other side of the upper end of the base 1, and a steel pipe diagonal brace 7 for reinforcing the truss 8 is installed in the middle of the upper end of the base 1. The steel pipe diagonal brace 7 is inclined, and one end thereof is welded and fixed to the truss 8. The truss 8 is welded by square tubes. A truss slot 81 is provided on the upper surface of the base 1 corresponding to the bottom of the truss 8. The truss 8 is fixed to the base 1 through the truss slot 81 and bolts. A recess for placing steel pipe piles is provided at the upper end of the base 1 corresponding to the iron lump 11, and the recess is for facilitating the driving of the steel pipe piles underwater. The height of the truss 8 is but not limited to 8m. The truss 8 can be fixed to the base 1 through the reserved truss slot 81, and the reinforcement of the steel pipe diagonal brace 7 can ensure the stability of the truss 8.

[0023] A pulley bracket 12 is provided on the top of the truss 8, and a pulley 13 is rotatably provided on the pulley bracket 12. A steel wire traction rope 9 is wound on the winch 5. One end of the steel wire traction rope 9 passes over the pulley 13 and is connected to an iron block 11. A lifting ring is installed on the top of the iron block 11, and one end of the steel wire traction rope 9 is fixed to the iron block 11 through the lifting ring. Track slide grooves are provided on both sides of the iron block 11, and limit blocks slidably connected to the two track slide grooves on the inner side of the truss 8 are welded. The steel wire traction rope 9 is fixed to the lifting ring, so that the lifting and traction of the iron block 11 can be realized, and there are track slide grooves on both sides of the iron block 11. The purpose is to ensure that the iron block 11 is always on the same vertical center line when it rises or falls, which is convenient for piling the steel pipe piles. In addition, it should be noted that the lifting ring on the top of the iron block 11 can also be used to lift the steel pipe pile, so that it is convenient to lift it to the piling position.

[0024] The working principle of the utility model is as follows: when working, the integrated device is floated in the river channel by the floating body 2, and the steel pipe pile can be suspended by the lifting ring. Before the first steel pipe pile is driven, a large rope is pulled on the shore to control the direction of the floating boat. After the steel pipe pile is adjusted to the driving position, it is lowered, and then the steel pipe pile is stabilized by a pipe clamp or a fixed frame to prevent it from shaking. Figure 2 As shown, Figure 2 A in the figure refers to the steel pipe pile. Further, the top of the steel pipe pile is fixed to the lifting ring;

[0025] The winch 5 is controlled to reel in, so that the iron mass 11 is pulled up to the top of the truss 8 through the wire traction rope 9, and then the winch 5 is controlled to quickly release the wire traction rope 9, so that the iron mass 11 falls vertically along the inner side of the truss 8 quickly, and the steel pipe pile is driven by the gravity of the iron mass 11. The above actions are repeated repeatedly until the steel pipe pile is completely driven into the water;

[0026] When constructing the second steel pipe pile, a large rope can be used to fix the floating boat on the first steel pipe pile, thereby stabilizing the floating boat and ensuring the pile position.

[0027] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
