Description

Technical Field

[0001] The utility model relates to a hydraulic breaker, in particular to a hydraulic breaker with a guiding structure. Background Art

[0002] A hydraulic breaker is an engineering mechanical equipment driven by hydraulic pressure, mainly used for breaking hard materials such as rocks and concrete. It is usually installed on an excavator, a loader or other construction machinery, and generates a powerful impact force through a hydraulic system to quickly and efficiently complete the breaking operation:

[0003] Due to the lack of a guiding structure, the impact force of the hydraulic breaker during operation is likely to be dispersed and cannot be effectively concentrated on the striking point of the drill rod, reducing the working efficiency. Moreover, the movement trajectory of the hydraulic breaker is unstable, and it may deviate or shake, resulting in the hydraulic breaker being more likely to be damaged or broken under high-intensity impacts.

[0004] It should be noted that the above content belongs to the technical cognitive scope of the utility model person and does not necessarily constitute the prior art. Summary of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide a hydraulic breaker with a guiding structure.

One ends of the four limiting discs are fixedly provided with buffer rods. The four buffer rods are inserted and connected with the corresponding buffer sleeves, and one ends of the four buffer rods are fixedly connected with the four corner positions on one side of the second guiding frame plate.

[0023] As Figures 1 to 4 shown, an embodiment of the present utility model provides a hydraulic breaker with a guiding structure, including a hydraulic energy storage tank 1:

[0024] A hammer head 2 is fixedly arranged at the output end of the hydraulic energy storage tank 1;

[0025] A first guiding frame plate 3 is fixedly arranged at one end of the hydraulic energy storage tank 1. The first guiding frame plate 3 is inserted and connected with the hammer head 2. The four corner positions on one side of the first guiding frame plate 3 are fixedly connected with one side of a second guiding frame plate 4 through buffer structures. Guide rods 8 are inserted through the middle positions on both sides of the second guiding frame plate 4. One ends of the two guide rods 8 are fixedly connected with one end of a guiding guide frame 7.

[0026] Specifically, the buffer structure includes buffer sleeves 5 fixedly arranged at the four corner positions on one side of the first guiding frame plate 3. First springs 13 are fixedly arranged inside the four buffer sleeves 5. One ends of the four first springs 13 are fixedly connected with one ends of corresponding limiting discs 11. Buffer rods 14 are fixedly arranged at one ends of the four limiting discs 11. The four buffer rods 14 are inserted and connected with the corresponding buffer sleeves 5. One ends of the four buffer rods 14 are fixedly connected with the four corner positions on one side of the second guiding frame plate 4.

[0027] Specifically, U-shaped frames 9 are fixedly arranged on both sides of the second guiding frame plate 4. Second springs 10 are sleeved at the positions where the two guide rods 8 are inside the corresponding U-shaped frames 9.

[0028] Specifically, the aperture diameter of the through hole of the guiding guide frame 7 is equal to the outer diameter of the hammer head 2.

[0029] Specifically, guiding grooves 6 are opened at the top and bottom of the inner wall of the second guiding frame plate 4. The two guiding grooves 6 are slidably connected with corresponding guiding rail plates 12. The two guiding rail plates 12 are fixedly arranged at the top and bottom of the outer wall of the guiding guide frame 7.

[0030] Working principle: The core function of the guiding structure is to ensure that the hammer head 2 moves up and down along a fixed trajectory during operation, avoiding the dispersion and deviation of the impact force. The hydraulic energy storage tank 1 accumulates energy through the hydraulic system and transfers this part of the energy to the hammer head 2 to push it to perform reciprocating up and down motion. When the hammer head 2 contacts the working surface, a huge impact force is released to complete the crushing operation. During this process, the hammer head 2 maintains the smoothness of its movement through the first guiding frame plate 3 and the second guiding frame plate 4. In the guiding structure, the first guiding frame plate 3 is connected to the second guiding frame plate 4 through a buffer structure. The buffer sleeve 5, the first spring 13 inside and the limit disk 11 can effectively absorb the impact vibration, reduce the equipment wear and improve the service life of the hammer head 2. When the hammer head 2 moves, guiding rods 8 are arranged on both sides of the second guiding frame plate 4. The guiding rods 8 provide additional stable support through the U-shaped frame 9 and the second spring 10 inside to ensure the positioning of the hammer head 2 during reciprocating motion. The outer diameter of the hammer head 2 is the same as the inner diameter of the through hole of the guiding frame 7. During the sliding process, the guiding groove 6 and the guiding rail plate 12 cooperate with each other to further ensure the precise movement of the hammer head 2 and avoid trajectory deviation.

[0031] The above are only the embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
