Description

Technical Field

[0001] A breaker mechanism for pavement repair operation belongs to the technical field of pavement repair. Background Technique

[0002] Pits, collapses, and cracks are common diseases in asphalt pavement damage. If pits, collapses, and cracks are not repaired in time, rainwater will pour into the pavement structure layer, which will evolve into more serious and large-area diseases such as spalling, loosening, and potholes, thereby greatly reducing the service life of the road. In the prior art, methods for pavement repair include non-grooving repair methods and grooving repair methods. Compared with traditional repair methods, grooving repair can make the repair material fully contact the interface of existing pits, collapses, and cracks, and the repair effect is better.

[0003] During grooving repair, it is generally divided into three processes: grooving, slot cleaning, and filling. The purpose of grooving is to expand the opening of the pit, so that the size and depth of the sunken part of the pavement are enlarged to a certain extent for subsequent filling. Currently, when grooving, it is generally completed by a hydraulically driven breaker. In the prior art, the hammer head of the breaker is generally a cylindrical hammer post, and the end of the hammer post is a tip to increase the pressure applied to the ground.

[0004] Although the traditional breaker structure can achieve the purpose of expanding the opening of the pit during the grooving stage, after the grooving is completed, the inner edge and the bottom of the expanded part of the pavement are both irregular concave and convex shapes. Not only is the subsequent slot cleaning work difficult, but also if the slot cleaning is not thorough, it will further affect the effect during subsequent filling, resulting in the pavement repair being difficult to achieve the expected strength. Content of the Utility Model

[0005] The technical problem to be solved by the present utility model is: to overcome the deficiencies of the prior art and provide a breaker mechanism for pavement repair operation that uses the cutter head at the end of the cutter assembly to cut the pavement material into sheets during grooving, ensuring the flatness of the inner edge and bottom of the pit.

[0006] The breaker mechanism for pavement repair operation of the present utility model includes a hammer head, and is characterized in that: a fixed seat is provided, a connecting seat is installed in the middle of the fixed seat, the hammer head is located at the side of the connecting seat and is inclined on the surface of the fixed seat, a cutter assembly is installed at the output end of the hammer head, and a cutter head is provided at the end of the cutter assembly.

[0007] Preferably, the angle of the hammer head is adjustable and is arranged on the surface of the connecting seat.

[0008] Preferably, a group of hammer head connecting plates are arranged opposite to each other on the surface of the fixing seat, a hammer head fixing plate is fixed on both sides of the hammer head respectively, a hammer head rotating shaft is provided which passes through both the hammer head connecting plate and the hammer head fixing plate, and an adjusting nut for locking the hammer head is also provided on the side of the hammer head connecting plate.

[0009] Preferably, the cutter assembly includes a drill rod fixed to the hammer head, a cutter head fixing plate is fixed to the bottom of the drill rod through a connecting sleeve, and the cutter head is fixed to the bottom of the cutter head fixing plate.

[0010] Preferably, the fixing seat comprises two fixing back plates which are spaced apart from each other, the two fixing back plates are connected by a connecting rod, and the connecting seat is clamped and fixed on the connecting rod.

[0011] Preferably, a fixing plate is detachably mounted on a side of the fixing seat facing away from the hammer head.

[0012] Preferably, fixed side panels are fixed to the ends of the two fixed back panels respectively, upper slots for clamping with the upper edges of the fixed panels are provided on the tops of the fixed side panels, and locking components for locking with the lower edges of the fixed panels are provided on the surfaces of the two fixed back panels.

[0013] Preferably, the locking assembly includes a handle, the middle part of the handle is rotatably connected to the fixed back plate via a hinge shaft, a locking rod is connected to the end of the handle, the handle is elastically connected to the locking rod, a pin is hinged at the bottom of the locking rod, and a guide sleeve is provided at the bottom of the fixed back plate, and the pin passes through the guide sleeve.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the breaker hammer mechanism of the road repair operation, the hammer head drives the cutter assembly to move back and forth. When the pits on the road are grooved, the cutter head at the end of the cutter assembly is used to cut the road material into sheets. After the grooves are grooved, the flatness of the inner edge and bottom of the pit is guaranteed. This not only facilitates the subsequent groove cleaning work, but also ensures the reliability of the filling work after the groove cleaning, thereby improving the road repair effect.

[0016] The cutter assembly and the fixing seat are arranged at an angle. Therefore, when grooving, the cutter head cuts the road surface in an inclined manner, which improves the working efficiency when grooving compared to the working method in which the hammer column at the end of the traditional breaker is perpendicular to the road surface.

[0017] In the breaker hammer mechanism of the present road repair operation, an adjusting nut is provided on the outside of the hammer head connecting plate. After the inner adjusting hole is aligned with different outer adjusting holes and then fixed by the adjusting nut, the inclination angle between the hammer head and the fixing seat can be adjusted.

[0018] At the end face of the fixed seat facing away from the hammer head, a fixed plate is detachably installed, and another device, preferably a sweeper, can be fixed at the other end face of the fixed plate. Thus, the installation of two different devices is realized through the fixed seat, achieving multi-functional use of one machine. Brief Description of the Drawings

[0025] Figures 1 - 6 Is the best embodiment of the present invention. The following further describes the present invention in conjunction with the attached Figures 1 - 6 drawings.

[0026] As Figure 1 shown, a breaker mechanism for road repair operations (hereinafter referred to as the breaker mechanism) includes a fixed seat 1. The fixed seat 1 is horizontally arranged. A connecting seat 2 is provided in the middle of the fixed seat 1 and is connected to a mechanical device in the prior art through the connecting seat 2. Taking an excavator as an example, the breaker mechanism of the present invention can be connected to the quick-release joint at the end of the bucket rod of the excavator through the connecting seat 2 to achieve the quick disassembly and assembly of the breaker mechanism.

[0027] On the side of the fixed seat 1, two hammer connecting plates 5 are symmetrically arranged. An axially penetrating hammer rotating shaft 3 is arranged above the two hammer connecting plates 5. The hammer 8 is installed between the two hammer connecting plates 5. The hammer 8 is realized by a common hydraulic hammer in the art. Hammer fixing plates 7 are respectively arranged on both sides of the hammer 8. The hammer 8 and the hammer fixing plates 7 on both sides thereof are placed between the two hammer connecting plates 5, and the hammer rotating shaft 3 simultaneously rotates from the tops of the two hammer fixing plates 7, thereby realizing the rotational connection between the hammer 8 and the fixed seat 1 through the hammer rotating shaft 3.

[0028] External adjustment holes are formed on the surface of at least one side of the hammer connecting plate 5, internal adjustment holes are formed on the surface of the hammer fixing plate 7, and an adjustment nut 6 is arranged outside the hammer connecting plate 5. After aligning the internal adjustment holes with different external adjustment holes, fixation is achieved through the adjustment nut 6, thereby realizing the adjustment of the inclination angle between the hammer 8 and the fixed seat 1.

[0029] At the end face of the fixed seat 1 facing away from the hammer 8, a fixing plate 4 is detachably installed, and another device, preferably a sweeper, can be fixed at the other end face of the fixing plate 4. Thus, the installation of two different devices is realized through the fixed seat 1, achieving multi-purpose of one machine.

[0030] In this breaker mechanism, a cutter assembly 9 is connected to the output end of the hammer 8. After connecting the hammer 8 to the hydraulic mechanism, the hammer 8 drives the cutter assembly 9 to reciprocate. When grooving the pothole on the road surface, the cutter head 29 at the end of the cutter assembly 9 is used to cut the road surface material into flakes. After grooving, the flatness of the inner edge and bottom of the pothole is ensured. This not only facilitates the subsequent groove cleaning work, but also ensures the reliability of the filling work after groove cleaning, improving the repair effect on the road surface.

[0031] And in this breaker mechanism, the cutter assembly 9 is inclined with respect to the fixed seat 1. Figure 5 The cutter assembly 9 includes a drill rod 26 fixed to the hammer 8. A cutter head fixing plate 28 is fixed to the bottom of the drill rod 26 through a connecting sleeve 27, and the cutter head 29 is fixed to the bottom of the cutter head fixing plate 28. Therefore, through the cutter head 29 at the end of the cutter assembly 9, the cutter head 29 cuts the road surface in an inclined manner during grooving. Compared with the operation mode in which the hammer post at the end of the traditional breaker is perpendicular to the road surface, the operation efficiency during grooving is improved.

[0032] Combined with Figures 2 - 3, the fixing base 1 includes two spaced fixing backplates 11, and the two fixing backplates 11 are connected into one body by two connecting rods 17 arranged vertically. A connecting seat clamping plate 14 is also fixed on the upper surface of the upper connecting rod 17. The above-mentioned connecting seat 2 includes two spaced connecting plates 13, and the two connecting plates 13 are simultaneously clamped and fixed with the two connecting rods 17 and the connecting seat clamping plate 14, realizing the fixation between the connecting seat 2 and the fixing base 1.

[0033] Two connecting shafts 12 are fixed on the upper part between the two connecting plates 13, and through the two connecting shafts 12, the fixation between the connecting seat 2 and the quick-release joint at the end of the excavator bucket rod is further realized.

[0034] On the outer ends of the two fixing backplates 11, a set of fixing side plates 10 are respectively fixed vertically. At the top of the fixing side plate 10 at the end of each fixing backplate 11, an upper clamping groove 16 is formed in a groove shape. Locking components 15 are also respectively arranged at the inner end faces of the two fixing backplates 11. Through the upper clamping grooves 16 at the tops of the two fixing backplates 11 and the locking components 15, the connection with the fixing plate 4 is realized.

[0035] As Figure 4 shown, the locking component 15 includes a handle 22, the middle of the handle 22 is bent, and at the bent part, it is rotatably installed on the end face of the fixing backplate 11 through a hinge shaft 18. A locking rod 21 is arranged at the end of the handle 22. A through slot is arranged in the middle of the locking rod 21, and the through slot is opened along the axial direction of the locking rod 21. A moving shaft 19 is arranged at the end. While the moving shaft 19 is rotatably connected with the handle 22, it passes through the through slot in the middle of the locking rod 21, so that relative displacement can occur between the end of the handle 22 and the locking rod 21.

[0036] A boss is arranged at the lower part of the locking rod 21. A spring 20 is simultaneously sleeved outside the locking rod 21. The bottom of the spring 20 is stuck at the boss at the lower part of the locking rod 21, and the upper end of the spring 20 contacts the end of the handle 22. A guide sleeve 24 is arranged at the bottom of the fixing backplate 11, and a pin shaft 25 passes through the guide sleeve 24. The end of the locking rod 21 is hinged to the top of the pin shaft 25 through a lifting shaft 23. A guide groove is also opened on the surface of the fixing backplate 11. While the lifting shaft 23 realizes the hinge connection between the locking rod 21 and the pin shaft 25, it passes through the guide groove.

[0037] When the handle 22 is lifted upward, the end of the handle 22 moves downward under the action of the hinge shaft 18. At this time, the moving shaft 19 moves axially along the locking rod 21 under the action of the through slot in the middle of the locking rod 21. While the moving shaft 19 and the locking rod 21 perform axial movement, the locking rod 21 is further pressed downward by pressing the spring 20. While the locking rod 21 moves downward, the pin shaft 25 in the guide sleeve 24 moves vertically downward under the action of the guide groove on the surface of the fixed back plate 11 and is led out from the bottom of the fixed back plate 11.

[0038] As Figure 6 shown, the fixing plate 4 includes a plate body 30. An upper edge of one end of the plate body 30 facing away from the fixed seat 1 is provided with a fixing plate clamping plate 31. A clamping groove is formed inside the fixing plate clamping plate 31. A clamping plate is horizontally arranged at the bottom of the fixing plate clamping plate 31. A fixing pin hole 32 is formed on the surface of the clamping plate.

[0039] When the fixed seat 1 is fixed to the fixing plate 4, the upper edge of the fixed back plate 11 is first inserted into the inside of the fixing plate clamping plate 31 from bottom to top. At this time, the clamping groove inside the fixing plate clamping plate 31 intersects with the upper clamping groove 16 at the top of the fixed side plate 10, so that the top of the fixed seat 1 is fixed to the fixing plate 4. Then, manually lift the handle 22 in the locking assembly 15 to make the pin shaft 25 extend out from the bottom of the fixed back plate 11 and enter the pin hole 32, so that the top of the fixed seat 1 is locked to the fixing plate 4.

[0040] The specific working process and working principle are as follows:

[0041] The quick-release joint at the end of the excavator's dipper arm is fixedly connected to the connecting seat 2 of the breaker mechanism. Then, the hydraulic mechanism in the excavator is connected to the hydraulic interface of the hammer head 8. When the hydraulic mechanism in the excavator works, it drives the hammer head 8 to work. At this time, the cutter head 29 at the end of the cutter assembly 9 is driven by the hammer head 8 to reciprocate, and the ground material at the ground pit is cut into flakes. After completing a certain range of cutting operations around the pit, the grooving treatment of the road surface pit is completed. Then, after cleaning and filling the pit, the repair of the road surface pit is completed.

[0042] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
