Description

Technical Field

[0001] This invention belongs to the field of excavator parts technology, specifically relating to an adjustable hydraulic breaker suitable for multiple construction sites for excavators. Background Technology

[0002] Excavators are large engineering equipment, equipped with buckets, breakers, or ramming plates at their front ends for construction work, such as excavation, road surface breaking, or roadbed compaction. In actual use, these accessories, such as breakers or ramming plates, are detachably installed at the front of the excavator. When road surface breaking or roadbed compaction is required, these accessories need to be constantly replaced, which is tedious and troublesome. Furthermore, when compacting road surfaces, there are two types: one is compacting flat roadbeds, which requires flat ramming plates; the other is compacting the roadbeds on both sides of V-shaped or inverted V-shaped ditches. Most existing roadbed compaction plates are flat, making it difficult to adapt traditional accessories to the corresponding construction sites when encountering V-shaped or inverted V-shaped roadbeds. This is a major headache in our current construction process, hence the urgent need to solve these problems. Summary of the Invention

[0003] To address the problems mentioned in the background section, this invention provides an adjustable hydraulic breaker suitable for various construction sites, enabling its use in multiple locations.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an adjustable hydraulic breaker adaptable to multiple construction sites for excavators, comprising a hydraulic breaker assembly, an adjustable base assembly being provided on both sides of the hydraulic breaker assembly, a foundation compaction plate assembly being rotatably provided at the bottom of the adjustable base assembly, a construction force-applying folding arm assembly being provided between the hydraulic breaker assembly, the adjustable base assembly and the foundation compaction plate assembly, the foundation compaction plate assembly forming an angle-adjustable foundation compaction platform structure on both sides of the hydraulic breaker assembly, the construction force-applying folding arm assembly forming a support arm structure for raising or lowering the foundation compaction plate assembly between the hydraulic breaker assembly and the adjustable base assembly, the adjustable base assembly forming an adjustable base structure with upper and lower pin positioning on both sides of the hydraulic breaker assembly, and the adjustable base assembly forming a drive base structure on both sides of the hydraulic breaker assembly for adjusting the roadbed compaction angle of the foundation compaction plate assembly;

[0007] Preferably, the foundation compaction plate assembly includes a foundation compaction platform, and the top two ends of the foundation compaction platform are respectively provided with platform shaft seats and platform shaft pin hole seats;

[0008] The construction force-applying folding arm assembly includes a first construction force-applying folding arm, a second construction force-applying folding arm rotatably disposed at the bottom of the first construction force-applying folding arm, and a third construction force-applying folding arm rotatably disposed at the middle of the first construction force-applying folding arm.

[0009] Preferably, the reset support platform is disposed in the side guide groove and slides up and down in the side guide groove, and the reset support platform slides up and down on the side guide slide rod through the reset slide hole. The two ends of the reset push spring respectively abut against the bottom of the side guide groove and the reset support platform. Through the push of the reset push spring, the adjusting base plate is in a natural upward structure on the outside of the top beam of the breaker hammer.

[0010] Preferably, the top of the first construction force-applying folding arm is rotatably mounted at the base plate axle seat on the adjusting base plate, the bottom of the second construction force-applying folding arm is rotatably mounted at the platform axle pin hole seat on the foundation compaction platform, and the bottom of the third construction force-applying folding arm is rotatably mounted at the top beam axle seat on the top beam of the breaker hammer.

[0011] Preferably, when the adjusting base assembly moves downward on one side of the breaker assembly, the first and third folding arms for applying construction force form an unfolded structure with the top beam shaft seat as the base point. When the adjusting base assembly moves upward on one side of the breaker assembly, the first and third folding arms for applying construction force form a folded structure with the top beam shaft seat as the base point.

[0012] Preferably, the tightening spring and the tightening end plate are disposed between the L-shaped support plate and the adjusting base plate, and the U-shaped positioning pin is disposed on the adjusting base plate through the positioning through hole. By the push of the tightening spring, the end of the U-shaped positioning pin is inserted into the positioning pin hole on the top beam of the breaker. The top beam shaft seat passes through the frame of the adjusting base plate through the vertical sliding groove of the base plate.

[0013] Preferably, when the U-shaped positioning pin on the adjusting base assembly is inserted into the positioning pin hole in the middle of the side of the top beam of the breaker, the two sets of foundation compaction plate assemblies form a flat compaction platform structure for compacting the flat roadbed on both sides of the breaker assembly. When the U-shaped positioning pin on the adjusting base assembly is inserted into the positioning pin hole at the top of the side of the top beam of the breaker, the two sets of foundation compaction plate assemblies form a compaction platform structure for compacting the V-shaped roadbed on both sides of the breaker assembly. When the U-shaped positioning pin on the adjusting base assembly is inserted into the positioning pin hole at the bottom of the side of the top beam of the breaker, the two sets of foundation compaction plate assemblies form a compaction platform structure for compacting the inverted V-shaped roadbed on both sides of the breaker assembly.

[0014] Preferably, when the U-shaped positioning pins on the two sets of adjusting base assemblies are inserted into the positioning pin holes at the top of the side of the top beam of the breaker, the two sets of foundation compaction plate assemblies fold towards both sides of the breaker assembly to form a folded storage structure. When the two sets of foundation compaction plate assemblies form a planar roadbed compaction platform structure, the two sets of foundation compaction plate assemblies will form a planar roadbed compaction platform structure below the breaker as the adjusting base assembly moves down.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The construction force-applying folding arm assembly of the present invention forms a support arm structure for the placement or retraction of the foundation compaction plate assembly between the breaker assembly and the adjusting base assembly. The adjusting base assembly forms a drive base structure on both sides of the breaker assembly for adjusting the roadbed compaction angle of the foundation compaction plate assembly. In actual use, a second construction force-applying folding arm is rotatably mounted at the bottom of the first construction force-applying folding arm, and a third construction force-applying folding arm is rotatably mounted in the middle of the first construction force-applying folding arm. Simultaneously, the top of the first construction force-applying folding arm is rotatably mounted at the base plate shaft seat on the adjusting base plate, the bottom of the second construction force-applying folding arm is rotatably mounted at the platform shaft pin hole seat on the foundation compaction platform, and the third construction force-applying folding arm... The bottom rotating assembly is located at the top beam axle seat on the top beam of the breaker hammer. The top beam axle seat passes through the frame of the adjustable base plate via a vertical sliding groove in the base plate. Pushed by a tension spring, the end of the U-shaped positioning pin is inserted into the positioning pin hole on the top beam of the breaker hammer. A row of positioning pin holes is provided on both sides of the side guide groove. When the adjustable base assembly moves down to one side of the breaker hammer assembly, the first and third construction force-applying folding arms form an unfolded structure with the top beam axle seat as the base point. At this time, when the U-shaped positioning pin on the adjustable base assembly is inserted into the positioning pin hole in the middle of the side of the breaker hammer top beam, the two sets of foundation compaction plate assemblies form a flat compaction platform structure on both sides of the breaker hammer assembly for compacting the flat roadbed. When the foundation compaction plate assembly forms a planar roadbed compaction platform structure, the two sets of foundation compaction plate assemblies will form a planar roadbed compaction platform structure below the breaker hammer as the adjusting base assembly moves downward. As it continues to move downward, when the U-shaped positioning pins on the adjusting base assembly are inserted into the positioning pin holes at the bottom of the side of the breaker hammer's top beam, the two sets of foundation compaction plate assemblies form a compaction platform structure on both sides of the breaker hammer assembly for compacting the inverted V-shaped roadbed. When the adjusting base assembly moves upward on one side of the breaker hammer assembly, a folding structure of the construction force-applying folding arm assembly is formed between the first and third construction force-applying folding arms, with the top beam shaft seat as the base point. At this time, when the U-shaped positioning pins on the adjusting base assembly are inserted into the positioning pin holes at the top of the side of the breaker hammer's top beam... Two sets of foundation compaction plate assemblies form a compaction platform structure on both sides of the breaker assembly for compacting V-shaped roadbeds. In this way, the compaction of flat roadbeds, V-shaped roadbeds, and inverted V-shaped roadbeds can be achieved. At the same time, the inclination angle of the V-shaped roadbeds and inverted V-shaped roadbeds can be adjusted according to the actual roadbed slope of the production site. When the U-shaped positioning pins on the two sets of adjusting base assemblies are inserted into the positioning pin holes at the top of the side of the breaker top beam, the two sets of foundation compaction plate assemblies fold and close to the sides of the breaker assembly to form a folded storage structure. In this state, the adjusting base assembly will lift the foundation compaction plate assemblies to the top of the breaker assembly, so that the breaker at the bottom of the breaker assembly is fully exposed for road surface crushing.

It passes through the positioning through hole 214 on the adjusting base plate 201. Pushed by the tensioning spring 209, the end of the U-shaped positioning pin 211 is inserted into the positioning pin hole 105 on the top beam 101 of the breaker. The top beam shaft seat 108 passes through the frame of the adjusting base plate 201 via the vertical sliding groove 202.

The bottom of the third construction force-applying folding arm 403 is rotatably mounted at... At the top beam axle seat 108 on the top beam of the breaker hammer 101, when the adjusting base assembly 200 moves down on one side of the breaker hammer assembly 100, the first construction force folding arm 401 and the third construction force folding arm 403 form an unfolded structure with the top beam axle seat 108 as the base point. When the adjusting base assembly 200 moves up on one side of the breaker hammer assembly 100, the first construction force folding arm 401 and the third construction force folding arm 403 form a folded structure with the top beam axle seat 108 as the base point.

[0034] The working principle and usage process of this invention: The construction force-applying folding arm assembly 400 of this invention forms a support arm structure for the placement or retraction of the foundation compaction plate assembly 300 between the breaker assembly 100 and the adjusting base assembly 200. The adjusting base assembly 200 forms a drive base structure on both sides of the breaker assembly 100 to drive the adjustment of the roadbed compaction angle of the foundation compaction plate assembly 300. In actual use, a second construction force-applying folding arm 402 is rotatably mounted at the bottom of the first construction force-applying folding arm 401, and a third construction force-applying folding arm 403 is rotatably mounted in the middle of the first construction force-applying folding arm 401. At the same time, the top of the first construction force-applying folding arm 401 is rotatably mounted at the base plate shaft seat 204 on the adjusting base plate 201. The second construction force-applying folding arm 402... The bottom of the first and third construction force-applying folding arms 403 is rotatably mounted on the foundation compaction platform 301 at the platform shaft pin hole seat 303. The bottom of the third construction force-applying folding arm 403 is rotatably mounted on the top beam shaft seat 108 on the top beam of the breaker hammer 101. The top beam shaft seat 108 passes through the frame of the adjustable base plate 201 via the vertical sliding groove 202 of the base plate. Through the push of the tightening spring 209, the end of the U-shaped positioning pin 211 is inserted into the positioning pin hole 105 on the top beam of the breaker hammer 101. A row of positioning pin holes 105 is provided on both sides of the side guide groove 104. When the adjustable base assembly 200 moves down on one side of the breaker hammer assembly 100, the first and third construction force-applying folding arms 401 and the third construction force-applying folding arm 403 form a construction force-applying folding arm assembly with the top beam shaft seat 108 as the base point. When the U-shaped positioning pin 211 on the adjusting base assembly 200 is inserted into the positioning pin hole 105 in the middle of the side of the breaker top beam 101, the two sets of foundation compaction plate assemblies 300 form a flat compaction platform structure for flat roadbed compaction on both sides of the breaker assembly 100. As the two sets of foundation compaction plate assemblies 300 form the flat roadbed compaction platform structure, they will move downwards with the adjusting base assembly 200 and form a flat roadbed compaction platform structure below the breaker 109. When moving downwards further, the U-shaped positioning pin 211 on the adjusting base assembly 200 is inserted into the positioning pin hole 105 at the bottom of the side of the breaker top beam 101, and the two sets of foundation compaction plate assemblies 300 form a flat roadbed compaction platform structure below the breaker 109. On both sides of the breaker assembly 100, a compaction platform structure is formed for compacting the inverted V-shaped roadbed. When the adjusting base assembly 200 moves upward on one side of the breaker assembly 100, the first construction force-applying folding arm 401 and the third construction force-applying folding arm 403 form a folding structure of the construction force-applying folding arm assembly 400 with the top beam shaft seat 108 as the base point. At this time, when the U-shaped positioning pin 211 on the adjusting base assembly 200 is inserted into the positioning pin hole 105 on the top side of the breaker top beam 101, the two sets of foundation compaction plate assemblies 300 form a compaction platform structure on both sides of the breaker assembly 100 for compacting the V-shaped roadbed. In this way, the compaction of the planar roadbed, V-shaped roadbed, and inverted V-shaped roadbed can be achieved. At the same time, the inclination angle of the V-shaped roadbed and the inverted V-shaped roadbed can be adjusted.Adjustments are made according to the actual roadbed slope at the production site. Simultaneously, when the U-shaped positioning pins 211 on the two sets of adjusting base assemblies 200 are inserted into the positioning pin holes 105 at the top of the side of the breaker top beam 101, the two sets of foundation compaction plate assemblies 300 fold towards both sides of the breaker assembly 100, forming a folded storage structure. In this state, the adjusting base assembly 200, along with the foundation compaction plate assemblies 300, rises to the top of the breaker assembly 100. This fully exposes the breaker hammer 109 at the bottom of the breaker assembly 100 for road surface breaking.
