[0005] As a further description of the above technical solution:

[0006] A plurality of slots are provided on the side surface of the cylinder body, and a plurality of the expansion cylinder blocks are inserted into the plurality of slots.

[0007] As a further description of the above technical solution:

[0008] Two opposite inner walls of the slot are provided with wedge-shaped grooves, and two opposite ends of the expansion cylinder block are provided with wedge-shaped strips, and the two wedge-shaped strips are respectively inserted into the two wedge-shaped grooves.

[0009] As a further description of the above technical solution:

[0010] The extended cylinder block is connected to the cylinder body via a plurality of fixing bolts.

[0011] As a further description of the above technical solution:

[0012] The cylinder body is provided with an air avoidance groove.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] In the utility model, the cylinder body is used as the basic cylinder module of the pile hammer. According to the requirements of the striking force, multiple extended cylinder blocks are installed on the cylinder body in a snap-on manner to meet the use requirements. There is no need to customize multiple models of cylinders, which reduces the production cost and greatly improves the flexibility and versatility of the cylinder body.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The utility model provides a technical solution: a cylinder module increase and decrease guide rod diesel pile hammer, comprising a cylinder body 1 and a plurality of extension cylinder blocks 2, wherein the cylinder body 1 is slidably connected to the pile hammer guide rod, and the plurality of extension cylinder blocks 2 are clamped on the cylinder body 1, and the plurality of extension cylinder blocks 2 are distributed around the pile hammer guide rod;

[0024] The side of the cylinder body 1 is provided with a plurality of slots 3, and the plurality of extended cylinder blocks 2 are inserted into the plurality of slots 3;

[0025] The two opposite inner walls of the slot 3 are provided with wedge-shaped grooves 4, and the two opposite ends of the expansion cylinder block 2 are provided with wedge-shaped strips 5. The two wedge-shaped strips 5 are respectively inserted into the two wedge-shaped grooves 4, so as to facilitate the stable clamping and installation of the expansion cylinder block 2 on the cylinder body 1;

[0026] The extended cylinder block 2 is connected to the cylinder body 1 via a plurality of fixing bolts 6, which facilitates the fixed installation between the two modules;

[0027] The cylinder body 1 is provided with an air avoidance groove 7 .

[0028] Working principle: The cylinder body 1 serves as the basic cylinder module of the pile hammer.
