DETAILED DESCRIPTION

[0026] The following will be combined with the 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.

[0027] The utility model provides a technical solution:

[0028] See also Figures 1 to 4A hydraulic breaker hammer with a static pressure support structure includes a shell 1, a connecting end 2 is embedded in the top of the shell 1, a cylinder 3 is fixedly installed on the upper part of the interior of the shell 1, a drill rod 4 is passed through the interior of the cylinder 3, and a stabilizing mechanism 5 is provided below the cylinder 3; the stabilizing mechanism 5 includes a fixed sleeve 501, the fixed sleeve 501 is embedded in the bottom end of the interior of the shell 1, and the outer wall of the fixed sleeve 501 at one end of the interior of the shell 1 is provided with a through groove 502, and a support rod 505 is fixedly installed in the through groove 502. The wall is slidably connected with a slider 504, and a slider 503 is fixedly installed on one end of the slider 504 passing through the through groove 502. A telescopic spring 506 is sleeved on the lower part of the outer wall of the support rod 505. The stabilizing mechanism 5 also includes a slide groove 507, which is opened inside the end of the fixed sleeve 501 passing through the outer shell 1. A block 508 is fixed on the outer wall of the drill rod 4 at the position corresponding to the slide groove 507. The slider 503 forms a sliding structure between the slider 504 and the fixed sleeve 501, and a sliding structure is formed between the slider 504 and the support rod 505.

[0029] By adopting the above technical solution, the outer shell 1 has a protective effect on each component, and the breaker hammer and the machine are connected through the connecting end 2, and the drill rod 4 is pushed through the cylinder body 3 to perform the crushing work. When the drill rod 4 slides, the slider 504 and the block 508 fixed on the outer wall slide along the corresponding through groove 502 and the slide groove 507 respectively, which has a preliminary effect of avoiding shaking and causing damage by collision. At the same time, the slider 504 is further limited by the support rod 505, and cooperates with the slide plate 503 to slide along the fixed sleeve 501, further improving the sliding stability of the drill rod 4 to avoid affecting the static pressure support, preventing mechanical friction or excessive collision from causing damage, and the elastic resistance of the telescopic spring 506 to avoid excessive collision and damage of the slider 504.

[0030] Specifically, such as Figure 2 and Figure 5 As shown, a fixed block 6 is fixedly installed on the outer wall of one end of the drill rod 4 passing through the top of the fixed sleeve 501, and a resistance mechanism 7 is provided above the fixed block 6. The resistance mechanism 7 includes a penetration rod 701, which is fixedly installed on the top of the fixed block 6. The penetration rod 701 penetrates into the outer wall of one end of the cylinder body 3 and is embedded with a mounting block 702. The external rotation of the mounting block 702 is connected to a roller 703. The resistance mechanism 7 also includes a bearing platform 704, which is fixedly installed on the top of the penetration rod 701. A damping shock-absorbing spring 705 is embedded on the top of the bearing platform 704. A sliding structure is formed between the penetration rod 701 and the cylinder body 3, and a sliding structure is formed between the cylinder body 3 and the roller 703.

[0031] By adopting the above technical solution, with the support of the fixed block 6, the penetration rod 701 slides along the inner wall of the cylinder 3, thereby improving the stability of the sliding process of the drill rod 4, and through the cooperation of the mounting block 702 and the roller 703, the smoothness of the sliding process is improved. At the same time, the damping shock-absorbing spring 705 embedded in the supporting platform 704 can avoid excessive collision and shaking, thereby preventing mechanical friction and damage.

[0032] Working principle: The hydraulic cylinder 3 is protected and fixed by the outer shell 1, and is conveniently connected to the machine through the connecting end 2. The drill rod 4 is driven by the cylinder body 3 to perform crushing work. The drill rod 4 passes through the fixed sleeve 501. At the same time, the slider 504 and the block 508 fixed on the outer wall respectively penetrate the through groove 502 and the slide groove 507 to limit and prevent shaking. The slider 504 is supported and guided by the support rod 505. At the same time, the slide plate 503 is fitted with the fixed sleeve 501, thereby improving the stability of the sliding process of the drill rod 4, and cooperating with the telescopic spring 506 to avoid excessive impact. The penetration rod 701 fixed by the fixed block 6 is inserted into the inner wall of the cylinder body 3, and cooperates with the mounting block 702 and the roller 703. It can improve the smoothness of the sliding process when limited by the penetration rod 701. The damping shock-absorbing spring 705 embedded in the bearing platform 704 prevents the drill rod 4 from excessive impact and shaking, and cannot play a static pressure support effect.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
