[0019] To make the purpose, technical scheme and advantages of the utility model embodiment more clear, the utility model technical scheme will be clearly and completely described below in conjunction with embodiment.

[0020] Embodiment 1: the utility model provides a kind of small diameter steel pipe's semicircle formula clamp, as shown in the figure: Figures 1 to 4As shown, including the fixed plate 1, fixed plate 1 top end by threaded rod and nut and vibration hammer connection, vibration hammer by amphibious excavator control, fixed plate 1 bottom fixedly connected with fixed block 2, fixed block 2 bottom inside opening has clamping groove 3, fixed block 2 inside at the position of clamping groove 3 clamping has clamping block 4, clamping block 4 bottom fixedly connected with positioning plate 5, positioning plate 5 movably connected in the fixed block 2, positioning plate 5 bottom fixedly connected with steel column 6, positioning plate 5 top screw thread connection has bolt 7, bolt 7 one end screw thread connection in the fixed block 2 inside, fixed block 2 bottom at the position of steel column 6 outside fixed installation has hydraulic machine 8, hydraulic machine 8 one end fixedly connected with arc clamping plate 9, arc clamping plate 9 away from the one end of hydraulic machine 8 fixedly connected with friction plate 10.

[0021] As shown in Figure 1 and Figure 4 , the steel column 6 is provided with an extrusion groove 11 in the inner end close to the friction plate 10, the spring 12 is fixedly connected in the inner end of the extrusion groove 11, the extrusion block 13 is fixedly connected at one end of the spring 12, the extrusion block 13 is movably connected in the inner end of the steel column 6, the limiting block 14 is fixedly connected at both sides of the extrusion block 13, the limiting block 14 is movably connected in the inner end of the steel column 6, the limiting block 14 limits the extrusion block 13 from sliding out of the inner end of the steel column 6 under the elastic force of the spring 12.

[0022] As shown in Figure 1 and Figure 4 , the steel column 6 is in the shape of a cone, the diameter of the one end close to the positioning plate 5 of the steel column 6 is greater than the diameter of the other end, which can ensure that the steel column 6 can be smoothly aligned and inserted into the steel pipe, and also can provide a certain fixing effect to ensure the stability after installation.

[0023] As shown in Figure 1 and Figure 4 , the end of the extrusion block 13 away from the positioning plate 5 is provided with an inclined surface, the guiding effect of the inclined surface can reduce the resistance when the extrusion block 13 is inserted into the inner end of the steel pipe, and the operation is more smooth.

[0024] As shown in Figure 1 and Figure 4 , the center of the steel column 6 and the center of the arc clamping plate 9 are on the same vertical line, which ensures that the arc clamping plate 9 can be extruded and fixed with the steel column 6 under the driving of the hydraulic machine 8, and ensures that the arc clamping plate 9 can be normally used.

[0025] As shown in Figure 1 and Figure 4 Figure 1 Figure 4 , the end face of the extrusion block 13 close to the friction plate 10 is a frosted surface, which can increase the friction force when the extrusion block 13 contacts with the inner wall of the steel pipe, and improves the stability of the steel pipe.

[0026] Working principle: during the actual use of the device, first, the fixed plate 1 is connected with the vibrating hammer, then the amphibious excavator controls the steel column 6 to align with the steel pipe, then the steel column 6 is controlled to move towards the steel pipe, the steel column 6 will move along the inner wall of the steel pipe, when the steel pipe contacts the extrusion block 13, since the bottom end of the extrusion block 13 is a slope, the steel pipe will exert force on the slope, so that the extrusion block 13 extrudes the spring 12 to make the spring 12 compressed, causing the extrusion block 13 to descend, so that the steel pipe will slowly move along the surface of the extrusion block 13, when the steel pipe reaches the bottom end surface of the fixed block 2, the hydraulic machine 8 is started to control the arc-shaped clamping plate 9 to move towards the steel column 6, with the movement, the friction plate 10 will contact the surface of the steel pipe, when the inner wall of the steel pipe and the outer surface of one side of the steel column 6 are completely attached, the clamping and fixing of the steel pipe are completed, and due to the elastic force of the spring 12, the spring 12 will extrude the extrusion block 13, the extrusion block 13 extrudes the steel pipe to form secondary extrusion and fixing, improving the fixing effect of the steel pipe, which can ensure the accurate butt joint of the steel pipe and the steel column 6, and can realize the stable clamping of the small-diameter steel pipe, significantly improving the fixing effect of the steel pipe;

[0027] Then when the steel column 6 needs to be maintained due to long-term use, the bolt 7 is loosened, after the bolt 7 is removed, the positioning plate 5 controls the clamping block 4 to move outward, so that the clamping block 4 is no longer clamped in the clamping groove 3, when the clamping block 4 completely separates from the clamping groove 3, the steel column 6 is successfully removed and can be maintained, after the maintenance is completed, the positioning plate 5 controls the clamping block 4 to align with the clamping groove 3, then the positioning plate 5 controls the clamping block 4 to move towards the clamping groove 3, when the clamping block 4 is completely clamped in the clamping groove 3, at this time, the preliminary fixing is completed, the bolt 7 is tightened, and the steel column 6 is fixed, which can realize the quick disassembly and installation of the steel column 6, facilitates the maintenance of the steel column 6, and improves the maintenance efficiency of the steel column 6.

[0028] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit them.
