Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combination Figures 1-5 A cylindrical diesel hammer includes a diesel hammer body 1, a lifting frame 2 that is connected through the top of the diesel hammer body 1, an oil inlet head 3 that is fixedly installed on the outside of the diesel hammer body 1, a mounting bracket 4 that is provided on the outside of the diesel hammer body 1, a release cylinder 5 that is provided near the bottom of the diesel hammer body 1, an oil supply pipe 6 that is connected to the top of the release cylinder 5, a lower piston head 7 and an upper piston head 8 that are symmetrically arranged inside the diesel hammer body 1, a limit stop block 9 that is fixedly installed near the top of the diesel hammer body 1, and a linkage indicator structure 10 that is connected to the top of the diesel hammer body 1.

[0024] See Figure 1 and Figure 3Furthermore, the linkage indicator structure 10 includes a fixed seat 11, an adjusting seat 12, and an indicator frame 13. The fixed seat 11 is fixed to the top of the diesel hammer body 1 and is sleeved on the outside of the landing gear 2. The adjusting seat 12 is located on the top of the fixed seat 11, and the indicator frame 13 is fixedly installed on the top of the adjusting seat 12.

[0025] Specifically, the lifting position of the diesel hammer's lifting gear 2 is indicated by the indicator frame 13, making it easy to understand the working position reached by the diesel hammer's transmission components.

[0026] See Figure 3 and Figure 4 Furthermore, a linkage frame 14 is provided on the inner side of the indicator frame 13. The linkage frame 14 is connected to the landing gear 2. An indicator head 15 is fixedly connected to the end of the linkage frame 14. A limit pin 16 is connected through the interior of the adjusting seat 12. A limit hole 17 matching the limit pin 16 is opened on the upper surface of the fixed seat 11. The adjusting seat 12 is fixedly connected to the fixed seat 11 by inserting the limit pin 16 into the limit hole 17.

[0027] Specifically, the lifting of the landing gear 2 causes the indicator head 15 to rise and fall together. The position of the indicator head 15 on the indicator frame 13 indicates the lifting position of the landing gear 2. Rotating the adjustment seat 12, the adjustment seat 12 is fixed to the fixed seat 11 after being inserted into different limit holes 17 by the limit pin 16, which facilitates the adjustment of the indication direction.

[0028] Example 2

[0029] See Figure 1 and Figure 5 Furthermore, based on Embodiment 1, a connecting frame 18 is fixedly installed on the outside of the diesel hammer body 1, an extension frame 19 is inserted inside the connecting frame 18, one end of the extension frame 19 is connected to the mounting frame 4, a threaded pin 20 is screwed into the top of the connecting frame 18, and a threaded groove 21 matching the threaded pin 20 is opened on the top of the connecting frame 18. The extension frame 19 is fixedly connected to the connecting frame 18 through the threaded pin 20 and the threaded groove 21.

[0030] Specifically, by pulling the extension frame 19, the extension frame 19 moves the mounting frame 4 to a suitable installation position. The extension frame 19 is then fixed to the connecting frame 18 via the threaded pin 20 and the threaded groove 21, thereby adjusting the installation spacing of the mounting frame 4.

[0031] It should be noted that this utility model is a cylindrical diesel hammer. During use, oil is injected into the release cylinder 5 through the oil inlet head 3 and the oil supply pipe 6. When the hammer starts, the winch starts, driving the lifting frame 2 to lift. The lifting frame 2 hoists the upper piston head 8 upwards. When the upper piston head 8 is lifted by the lifting frame 2 to the limit stop 9, the limit stop 9 touches the upper piston head 8, and the upper piston head 8 falls under gravity. The fuel pump injects diesel fuel and compresses the air in the release cylinder 5. When the upper piston head 8 strikes the lower piston head 7 and ignites the oil mist and high-pressure air in the combustion chamber, it explodes. The explosive force continues to drive the pile while simultaneously lifting the upper piston head 8 upwards. In the next work cycle, pull the extension frame 19. The extension frame 19 drives the mounting frame 4 to the appropriate installation position. Fix the extension frame 19 to the connecting frame 18 through the threaded pin 20 and threaded groove 21 to adjust the installation spacing of the mounting frame 4. The lifting of the landing gear 2 drives the indicator head 15 to rise and fall together. Observe the position of the indicator head 15 on the indicator frame 13 to see the lifting position of the landing gear 2, so as to understand the working position of the diesel hammer transmission component. Rotate the adjusting seat 12. The adjusting seat 12 is fixed to the fixed seat 11 after rotation by inserting the limiting pin 16 into different limiting holes 17, so as to adjust the indicating direction.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
