Technical Field

[0001] The utility model relates to the technical field of hydraulic break hammers, and particularly relates to a middle cylinder body assembly of a hydraulic break hammer. Background Art

[0002] A hydraulic break hammer is a heavy equipment used for construction and demolition operations. It generates a powerful impact force through a hydraulic system to break concrete, rocks or other solid materials. The hydraulic break hammer is usually installed on an excavator or other robotic arms to improve construction efficiency and handle difficult demolition tasks. The middle cylinder body assembly of the break hammer is a key component of the equipment, which plays a role in supporting and transmitting forces during the working process of the hydraulic break hammer.

[0003] In the existing middle cylinder body assembly of a hydraulic break hammer, the front, middle and rear cylinders are only connected together by a series of bolts, nuts and seals. The simple bolt connection cannot provide sufficient structural stability. Especially under high load and impact working conditions, the lack of additional reinforcement may cause the cylinder body components to vibrate, shift or deform during operation, so it has certain limitations.

Embodiment

[0020] Please refer toFigures 1-3 , the present utility model provides a technical solution:

[0021] A middle cylinder body assembly of a hydraulic breaker, including a rear cylinder body assembly 1, the bottom end of the rear cylinder body assembly 1 is threadedly connected with a middle cylinder body assembly 2, the bottom end of the middle cylinder body assembly 2 is threadedly connected with a front cylinder body assembly 3, a drill rod 4 is movably installed inside the front cylinder body assembly 3, and reinforcing rods 5 are snap-connected at the four corners of the outer wall of the middle cylinder body assembly 2. Installation plates 7 are provided at both ends of the four reinforcing rods 5. Through holes 9 are opened at a corresponding corner of the two groups of installation plates 7. The inner walls of the plurality of through holes 9 are threadedly connected with fastening bolts 10. The sizes of the plurality of installation plates 7 are the same. The provided reinforcing rods 5 are evenly distributed outside the cylinder body, providing additional support force to the cylinder body, enhancing the overall stability of the cylinder body assembly, preventing the structure from deforming or loosening due to vibration and impact generated during operation, and reducing the wear of the cylinder body and other key components by dispersing and reducing local stress, thereby improving the service life and durability of the equipment.

[0022] In this embodiment, a part of the outer wall of one group of fastening bolts 10 is threadedly connected with one end of the rear cylinder body assembly 1, and a part of the outer wall of the other group of fastening bolts 10 is threadedly connected with one end of the front cylinder body assembly 3. Through slots 6 are opened at the top and bottom of the outer walls of the four reinforcing rods 5. Slots 8 are opened on the inner walls of the two groups of installation plates 7. Both ends of the four through slots 6 are snap-connected with the slots 8 opened on the inner wall of the installation plate 7. The sizes of the four reinforcing rods 5 are the same. The provided slots 8 and through slots 6 play a role in assisting the insertion and fixation between the reinforcing rods 5 and the installation plates 7, facilitating individual installation and disassembly, and also facilitating subsequent replacement and maintenance.

[0023] In this embodiment, buffer pads 11 are wrapped around the outer walls of the four reinforcing rods 5.
