Description

Technical Field

[0001] The invention relates to the technical field of crushing devices, in particular to a hydraulic breaker. Background Art

[0002] Hydraulic breaker is a kind of engineering machinery widely used in construction, mining, highway, bridge and other engineering fields. It is mainly used to break hard materials such as concrete and rock. Its working principle is to use the high-pressure oil generated by the hydraulic system to drive the piston of the breaker to reciprocate at high speed, thereby exerting impact force on the material to achieve the breaking effect. The product characteristics of hydraulic breaker include high efficiency and high precision breaking capacity, which can quickly break hard materials while controlling the breaking precision to avoid unnecessary damage to the surrounding environment. In addition, the design of hydraulic breaker usually takes into account the convenience of maintenance and durability.

[0003] When the hydraulic breaker is working, due to the high hardness of the rock, it needs to work repeatedly. When working on the rock repeatedly, the hydraulic breaker will vibrate greatly. This vibration will cause fatigue and damage to the internal parts of the hydraulic breaker. Key components such as pistons, bushings, bolts, etc. may crack or break due to long-term vibration, thereby shortening the service life of the equipment. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1, reference Figures 1 to 5, which is the first embodiment of the present invention, provides a hydraulic breaker that can reduce the damage caused by the device during operation.

[0028] Specifically, it includes a support assembly 100, including a support body 101, a bearing shell 102 disposed inside the support body 101, and a breaker 103 disposed inside the bearing shell 102; and,

[0029] The buffer assembly 200 includes a first connecting plate 201 disposed on the outside of the breaker 103 and a second connecting plate 207 disposed on the outside of the breaker 103 .

[0030] The support assembly 100 further includes a pin sleeve 101 a disposed inside the support body 101 .

[0031] Usage process: When the hydraulic hammer is breaking rocks, when the hardness of the rocks is high, the hydraulic hammer needs to work on the rocks repeatedly, and the hydraulic hammer will vibrate violently. In the process of the breaker hammer 103 hitting the rocks to cause vibrations, the buffer component 200 on the outside of the breaker hammer 103 will slow down the vibration amplitude of the breaker hammer 103 under the action of the elastic force of the buffer component 200, thereby slowing down the overall vibration amplitude.

[0032] Example 2, reference Figures 1 to 5 , which is the second embodiment of the present invention, provides a hydraulic breaker that can achieve the effect of reducing vibration during operation.

[0033] Specifically, it includes: the buffer assembly 200 also includes a first rotating shaft 201a-2 arranged on both sides of the first connecting plate 201, the first connecting plate 201 is arranged on the outer side of the first rotating shaft 201a-2, the first connecting plate 201 is arranged on the outer side of the first connecting plate 201, the first tooth block 201a-1 is arranged on the outer side of the first turntable 201a, the first cover plate 202 is arranged on the outer side of the first turntable 201a, and the first arc plate 203 is arranged between the first turntables 201a.

[0034] A second rotating shaft 204a-1 is provided on both sides of the second connecting plate 207, a second rotating disc 204 is provided on the outer side of the second rotating shaft 204a-1, a second tooth block 204a is provided on the outer side of the second rotating disc 204, a second cover plate 205 is provided on the outer side of the second rotating disc 204, and a second arc plate 206 is provided between the second rotating discs 204. A first elastic member 205a is provided at one end of the first rotating disc 201a, and the first elastic member 205a is a tension spring. A second elastic member 205b is provided at one end of the second rotating disc 204, and the second elastic member 205b is a reset spring. When the breaker 103 repeatedly works on the rock, the breaker 103 will reciprocate up and down. When the breaker 103 moves downward, the amplitude of its vibration will be reduced by the operation of the elastic force of the first elastic member 205a and the second elastic member 205b. When the breaker 103 rises, the buffer assembly 200 will reset to complete the initialization state.

[0035] Usage process: When the breaker 103 moves downward to break the rock, the breaker 103 will drive the first connecting plate 201 to move downward, and the first connecting plate 201 will drive the first rotating discs 201a on both sides to move downward at the same time. At this time, the first tooth blocks 201a-1 on the outer sides of the first rotating disc 201a will mesh with each other, and drive the first rotating disc 201a below to mesh with the second rotating disc 204, so that the first rotating disc 201a below and the second rotating disc 204 above extend to both sides. When the first rotating disc 201a below and the second rotating disc 204 extend to both sides, the first rotating disc 201a below 201a and the second turntable 204 will simultaneously pull the first elastic member 205a and the second elastic member 205b between the two sides. When the first elastic member 205a and the second elastic member 205b are pulled, the first elastic member 205a and the second elastic member 205b will generate a rebound force to pull the first turntable 201a and the second turntable 204 below to increase their kinetic energy for restoration, thereby reducing the amplitude of vibration of the breaker 103 when it repeatedly breaks rocks, preventing long-term vibration from causing cracks or breakages in the internal workpiece, thereby shortening the service life of the equipment.

[0036] Example 3, reference Figures 1 to 5 , which is the third embodiment of the present invention, and this embodiment provides a hydraulic breaker that can prevent the device from being subjected to impact force and rebounding when the rock is not penetrated.

[0037] Specifically, it also includes a protection component 300, which includes a limit groove 301 opened on the outside of the breaker 103, a limit block 301a is provided on the limit groove 301, a first reset block 302 is provided on the outside of the breaker 103, and a ramp block 303 is provided on the outside of the breaker 103.

[0038] An extrusion block 303a is provided inside the bearing housing 102, a connecting shaft 304c is provided inside the bearing housing 102, a rotating column 304 is provided outside the connecting shaft 304c, a first operating plate 304a is provided above the rotating column 304, and a second operating plate 304b is provided below the rotating column 304. A long plate 305 is provided between the second operating plates 304b, and a blocking block 305a is provided at one end of the long plate 305. A second reset block 306 is provided outside the breaker 103.

[0039] When the breaker 103 moves downward to work on the rock, the limit block 301a is below the stop block 305a, and the breaker 103 drives the inclined plane block 303 to move downward. During the downward movement of the inclined plane block 303, the inclined plane block 303 will contact the extrusion block 303a. At this time, through the setting of the inclined surface at the lower end of the inclined plane block 303 and the setting of the smooth curved surface at the rear end of the extrusion block 303a, when the inclined plane block 303 moves downward, the inclined plane block 303 will squeeze the extrusion block 303a below. At this time, after the extrusion block 303a is squeezed, the extrusion block 303a will slide outward, and the extrusion block 303a will be pushed outward. 03a slides, the squeezing block 303a will also contact the first operating plate 304a and squeeze the first operating plate 304a. At this time, the first operating plate 304a will swing backward. When the first operating plate 304a swings backward, the first operating plate 304a will drive the rotating column 304 to rotate with the connecting shaft 304c as the axis. The rotating column 304 will drive the second operating plate 304b to swing inward. When the rotating column 304 swings inward, the rotating column 304 drives the long plate 305 and the blocking block 305a at one end of the long plate 305 to move inward. At this time, the blocking block 305a and the limit block 301a are located in the same plane. Then, when the breaker 103 rebounds due to the impact force, the breaker 103 will be blocked by the blocking block 305a during the rising process of the breaker 103, thereby avoiding damage to the device caused by rebound due to the impact force.
