Description

Technical Field

[0001] This invention relates to the field of road compaction equipment technology, and in particular to a road construction compaction equipment and its compaction process. Background Technology

[0002] Road compaction is a construction operation that uses heavy objects to repeatedly impact soil or fill materials to increase their density. It is mainly used in infrastructure projects such as roads and bridges. Its core purpose is to enhance the bearing capacity of the foundation and ensure the stability and durability of the road structure. Compaction equipment uses the impact force generated by the free fall of heavy objects (such as tampers and rollers) to compact the soil or fill materials.

[0003] When compacting roads, a significant amount of dust is generated. To reduce dust generation, the ground needs to be treated for dust suppression beforehand, which increases the labor intensity. Existing compaction equipment has hydraulic components that are directly fixed to the hammer. During the compaction process, the strong reaction force causes the hydraulic cylinder and connecting parts to bear a large impact force, which can easily lead to fatigue damage. Summary of the Invention

[0004] Technical problems to be solved: To address the shortcomings of existing technologies, this invention provides a road construction compaction device and its compaction process. A connecting component is added between the hydraulic cylinder assembly and the hammer head. When the hammer head falls, the connecting component is controlled to disconnect the connection between the hammer head and the hydraulic cylinder assembly. As the hammer head falls and strikes the lower hammer body and the compaction plate, the hydraulic cylinder assembly and the hammer head are in a separated state. This reduces the reaction force transmitted from the hammer head to the hydraulic cylinder assembly without affecting the hammering effect. Dust suppression is achieved through a dust suppression component, thus solving the technical problems mentioned in the background art.

[0005] Technical solution: To achieve the above objectives, the present invention provides the following technical solution: A road construction compaction device includes a compaction frame, which houses a hydraulic cylinder assembly and a hammer head. The hydraulic cylinder assembly and the hammer head are connected by a connecting assembly. An additional connecting assembly is provided between the hydraulic cylinder assembly and the hammer head. A lower hammer body is located at the bottom of the compaction frame, and a compaction plate is located at the lower end of the lower hammer body. The connecting assembly includes a mounting frame and a fixing frame. A motor is mounted on the mounting frame, and the output shaft of the motor is fixedly connected to a screw. An adjusting sleeve is fitted onto the screw. First drive arms are rotatably mounted on both sides of the fixing frame. The first drive arms are rotatably connected to second drive arms. The second drive arms are connected to the fixing frame via connecting plates. Connecting shafts are fixedly mounted on the inner surfaces of both sets of second drive arms. A lifting seat is located at the top of the hammer head, and a slot is formed on the lifting seat. The connecting shaft extends into the slot of the lifting seat. The hammer head is hung on the connecting assembly. An assembly base is welded and fixed to the compaction frame and mounted on a loader. A dust suppression component is fixedly mounted on the compaction frame for dust suppression.

[0006] In one possible implementation, the loader includes an adjustment assembly for driving the ramming frame, and the assembly base is provided with a first connecting ear plate, a second connecting ear plate, and a third connecting ear plate, which respectively form connection positions.

[0007] In one possible implementation, the adjusting assembly includes a first hydraulic cylinder, a second hydraulic cylinder, and a third hydraulic cylinder. The push rod of the first hydraulic cylinder is connected to a first connecting lug via a first connecting arm, the push rod of the second hydraulic cylinder is connected to a second connecting lug via a second connecting arm, and the push rod of the third hydraulic cylinder is connected to a third connecting lug via a third connecting arm.

[0008] In one possible implementation, the ramming frame has multiple sets of slotted structures for the entry and exit of hydraulic oil circuits and wiring components. The top of the mounting frame is provided with a connecting seat, and one end of the push rod of the hydraulic cylinder assembly is fixedly connected to a connector, which is connected to the connecting seat of the mounting frame.

[0009] In one possible implementation, the adjusting sleeve is rotatably connected to the first drive arm via a rotating shaft, the first drive arm is rotatably connected to the fixed frame via a rotating shaft, the first drive arm is rotatably connected to the second drive arm via a rotating shaft, one end of the connecting plate is rotatably connected to the second drive arm via a rotating shaft, the other end of the connecting plate is rotatably connected to the fixed frame via a rotating shaft, one end of the screw is fixedly connected to the output shaft of the motor via a coupling, and the other end of the screw is connected to the fixed frame via a bearing. The motor serves as a power source, driving the second drive arms on both sides of the end of the connecting assembly to perform an outward opening or inward closing action.

[0010] In one possible implementation, the dust suppression component includes a dust suppressant storage tank and a spray pipe, the spray pipe including a connecting pipe, and the dust suppressant storage tank storing dust suppressant.

[0011] In one possible implementation, a pump body is provided on one side of the dust suppressant storage tank. Both the dust suppressant storage tank and the pump body are mounted on a loader. One end of the pump body is connected to the dust suppressant storage tank via a liquid extraction pipe, and the other end of the pump body is connected to a connecting pipe via a delivery hose.

[0012] In one possible implementation, the spray pipe is fixed to the outer surface of the rammer frame.

[0013] In one possible implementation, the spray pipe is provided with multiple sets of spray nozzles, which are evenly distributed at intervals. When the pump works, it extracts the dust suppressant from the dust suppressant storage tank and sends it to the delivery hose. The dust suppressant enters the spray pipe through the delivery hose and is finally sprayed out to the surrounding area through the multiple sets of spray nozzles in the spray pipe.

[0014] A compaction process for a road construction compaction device includes the following steps: Step 1: Install the tamping frame of the compactor onto the loader, connect the loader's adjustment mechanism, and adjust the working position of the compactor using the adjustment mechanism; Step 2: The operator drives the loader to the designated work position, and under the drive of the adjustment component, the compaction equipment is erected and the ground is compacted. The lifting seat of the hammer head is hung on the connecting shaft of the connecting component, and the hammer head is lifted under the drive of the hydraulic cylinder component. Step 3: After the hydraulic cylinder assembly lifts the hammer head to the designated height, it quickly applies reverse force. Under the combined action of its own weight and the thrust of the hydraulic cylinder assembly, the hammer head accelerates to fall. During the fall, the motor of the connecting assembly works, driving the second drive arms on both sides of the end to open outward. The second drive arms drive the connecting shaft on their inner side to move synchronously and open, releasing the hammer head and disconnecting the connection between the hydraulic cylinder assembly and the hammer head. The hammer head falls freely and strikes the lower hammer body after falling. The lower hammer body strikes the tamping plate, driving the tamping plate pre-pressed on the ground to compact the ground. Step 4: During the compaction operation, the pump extracts the dust suppressant from the storage tank and sends it to the delivery hose. The dust suppressant enters the spray pipe through the delivery hose and is sprayed outwards through multiple spray nozzles to suppress dust. Step 5: After one compaction action is completed, the hydraulic cylinder assembly drives the connecting assembly to move down to the designated position. The motor of the connecting assembly works, and the second drive arms on both sides of the drive end close inward. The second drive arms drive the connecting shaft on their inner side to move synchronously and close. The connecting shaft re-enters the slot of the lifting seat, reconnecting the hydraulic cylinder assembly and the hammer head. Driven by the hydraulic cylinder assembly, the hammer head is lifted, and the above actions are repeated. The ground is compacted by the hammer head repeatedly striking the tamping plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention adds a connecting component between the hydraulic cylinder assembly and the hammer head. The second drive arms on both sides of the end of the connecting component can open outward and close inward under the drive of the motor. When the hammer head falls, the connecting component is controlled to disconnect the connection between the hammer head and the hydraulic cylinder assembly. When the hammer head falls and strikes the hammer body and the tamping plate, the hydraulic cylinder assembly and the hammer head are in a separated state. This reduces the reaction force transmitted from the hammer head to the hydraulic cylinder assembly without affecting the hammering effect, thus reducing the impact force and protecting the hydraulic cylinder assembly from fatigue damage, extending the service life of the compaction equipment. After one compaction action is completed, the connecting component is controlled to reconnect the hammer head and the hydraulic cylinder assembly. Driven by the hydraulic cylinder assembly, the hammer head is raised to a certain height, and the above action is repeated. The ground is compacted by the hammer head repeatedly striking the tamping plate.

[0016] 2. The present invention adds a dust suppression component to the tamping frame, which can spray dust suppressant onto the ground to suppress dust during the tamping operation. There is no need to perform dust suppression on the ground before the tamping operation, and the dust suppression operation and the tamping operation can be carried out simultaneously, reducing labor intensity.

[0020] This application provides a road construction compaction device and its compaction process. By adding a connecting component between the hydraulic cylinder assembly and the hammer, when the hammer falls, the connecting component is controlled to disconnect the connection between the hammer and the hydraulic cylinder assembly. When the hammer falls and strikes the hammer body and the compaction plate, the hydraulic cylinder assembly and the hammer are in a separated state. This reduces the reaction force transmitted from the hammer to the hydraulic cylinder assembly without affecting the hammering effect. Dust is suppressed by a dust suppression component, thus solving the technical problems mentioned in the background art.

[0021] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example 1: Please see Figure 1-10This invention provides a technical solution: a road construction compaction device, including a compaction frame 1, which houses a hydraulic cylinder assembly 2 and a hammer head 4. The hydraulic cylinder assembly 2 and the hammer head 4 are connected by a connecting assembly 3. A lower hammer body 5 is provided at the bottom of the compaction frame 1, and a compaction plate 6 is provided at the lower end of the lower hammer body 5. The connecting assembly 3 includes a mounting frame 31 and a fixing frame 32. A motor 33 is mounted on the mounting frame 31, and the output shaft of the motor 33 is fixedly connected to a screw 34. An adjusting sleeve 35 is fitted on the screw 34. Both sides of the frame 32 are rotatably equipped with first drive arms 36, which are rotatably connected to second drive arms 37. The second drive arms 37 are connected to the fixed frame 32 through connecting plates 38. Connecting shafts 39 are fixedly installed on the inner sides of both sets of second drive arms 37. The top of the hammer head 4 is equipped with a lifting seat 41, which has a slot 42. An assembly base 7 is welded and fixed on the ramming frame 1. The assembly base 7 is installed and fixed on the loader 8. A dust suppression component 9 is fixedly installed on the ramming frame 1.

[0022] A connecting component 3 is added between the hydraulic cylinder assembly 2 and the hammer head 4. One end of the connecting component 3 is connected to the hydraulic cylinder assembly 2, and the other end is connected to the hammer head 4. The second drive arms 37 on both sides of the end of the connecting component 3 can open outward and close inward under the drive of the motor 33. Figure 6 As shown, when the connecting component 3 is connected to the hammer head 4, the connecting shaft 39 of the second drive arm 37 on both sides of the end of the connecting component 3 passes through the slot 42 of the upper lifting seat 41 of the hammer head 4. At this time, the hammer head 4 is hung on the connecting component 3, realizing the connection between the connecting component 3 and the hydraulic cylinder assembly 2. The hammer head 4 can move axially under the drive of the hydraulic cylinder assembly 2, and the hammer head 4 can be lifted by the hydraulic cylinder assembly 2 to a specified height position.

[0023] During free fall, the hydraulic cylinder assembly 2 lifts the hammer head 4 to a specified height and then releases it. The hammer head 4 falls under its own weight. After falling, the hammer head 4 strikes the hammer body 5 and the tamping plate 6, driving the tamping plate 6 pre-pressed on the ground to compact the soil and carry out the compaction operation. When the hammer head 4 is released, the motor 33 drives the connecting shaft 39 of the second drive arm 37 on both sides of the end to open outward, moving the connecting shaft 39 out of the slot 42 of the upper lifting seat 41 of the hammer head 4, releasing the connection between the two. The hammer head 4 falls under its own weight to carry out free fall compaction.

[0024] During forced hammer drop, the hydraulic cylinder assembly 2 lifts the hammer head 4 to a specified height, and then quickly applies reverse force. Under the combined action of its own weight and the thrust of the hydraulic cylinder assembly 2, the hammer head 4 accelerates its fall. During the fall, the motor 33 drives the connecting shaft 39 of the second drive arm 37 on both sides of the end to open outward, moving the connecting shaft 39 out of the slot 42 of the upper lifting seat 41 of the hammer head 4, thus detaching the connection between the two. The hammer head 4 accelerates its fall and strikes the lower hammer body 5, which in turn strikes the tamping plate 6, driving the tamping plate 6 pre-pressed on the ground to compact the ground and improve the compaction quality. The hammer drop method can be selected according to actual usage requirements.

[0025] After one compaction action is completed, the hydraulic cylinder assembly 2 drives the connecting assembly 3 to move down to the designated position. The motor 33 drives the connecting shaft 39 of the second drive arm 37 on both sides of the end to close inward. The connecting shaft 39 re-enters the slot 42 of the lifting seat 41, reconnecting the hydraulic cylinder assembly 2 and the hammer head 4. Driven by the hydraulic cylinder assembly 2, the hammer head 4 is raised to a certain height. The above action is repeated, and the ground is compacted by the hammer head 4 repeatedly hitting the tamping plate 6.

[0026] When the hammer head 4 falls and strikes the hammer body 5 and the tamping plate 6, the hydraulic cylinder assembly 2 is separated from the hammer head 4. This reduces the reaction force transmitted from the hammer head 4 to the hydraulic cylinder assembly 2 without affecting the hammering effect of the hammer head 4, thus reducing the impact force and protecting the hydraulic cylinder assembly 2 from fatigue damage, thereby extending the service life of the compaction equipment.

[0027] In some examples, the loader 8 includes an adjustment assembly 81 for driving the ramming frame 1, and the mounting base 7 is provided with a first connecting ear plate 71, a second connecting ear plate 72 and a third connecting ear plate 73, which respectively form connection positions.

[0028] In some examples, the adjustment assembly 81 includes a first hydraulic cylinder 811, a second hydraulic cylinder 812, and a third hydraulic cylinder 813. The push rod of the first hydraulic cylinder 811 is connected to the first connecting ear plate 71 via a first connecting arm 814. The push rod of the second hydraulic cylinder 812 is connected to the second connecting ear plate 72 via a second connecting arm 815. The push rod of the third hydraulic cylinder 813 is connected to the third connecting ear plate 73 via a third connecting arm 816.

[0029] like Figure 3 and Figure 4As shown, the first connecting ear plate 71 of the tamping frame 1 is connected to the first hydraulic cylinder 811 of the loader 8, the second connecting ear plate 72 of the tamping frame 1 is connected to the second hydraulic cylinder 812 of the loader 8, and the third connecting ear plate 73 of the tamping frame 1 is connected to the third hydraulic cylinder 813 of the loader 8. The first connecting arm 814, the second connecting arm 815, and the third connecting arm 816 are driven by the first hydraulic cylinder 811, the second hydraulic cylinder 812, and the third hydraulic cylinder 813, respectively. The tamping frame 1 is driven by the first connecting arm 814, the second connecting arm 815, and the third connecting arm 816. The angle and height of the tamping frame 1 can be adjusted according to the ground shape. When carrying out tamping operations, the tamping equipment can be erected and the ground can be initially compacted to prepare for the tamping operation.

[0030] In some examples, the ramming frame 1 has multiple sets of slotted structures, the top of the mounting frame 31 is provided with a connecting seat 311, one end of the push rod of the hydraulic cylinder assembly 2 is fixedly connected to a connector 21, the connector 21 is connected to the connecting seat 311 of the mounting frame 31, and the multiple sets of slotted structures on the ramming frame 1 are used for the entry and exit of hydraulic oil circuits and wiring components.

[0031] In some examples, the adjusting sleeve 35 is rotatably connected to the first drive arm 36 via a rotating shaft, the first drive arm 36 is rotatably connected to the fixed frame 32 via a rotating shaft, the first drive arm 36 is rotatably connected to the second drive arm 37 via a rotating shaft, one end of the connecting plate 38 is rotatably connected to the second drive arm 37 via a rotating shaft, the other end of the connecting plate 38 is rotatably connected to the fixed frame 32 via a rotating shaft, one end of the screw 34 is fixedly connected to the output shaft of the motor 33 via a coupling, and the other end of the screw 34 is connected to the fixed frame 32 via a bearing.

[0032] When the motor 33 is working, it drives the screw 34 at one end to rotate, which in turn drives the adjusting sleeve 35 to move along the axis of the screw 34. When the adjusting sleeve 35 moves, it drives the first driving arm 36 to rotate relative to the fixed frame 32. The first driving arm 36 drives the second driving arm 37 to move. The second driving arm 37 drives the connecting shaft 39 to move. The deflection direction and deflection angle of the second driving arm 37 are controlled by the rotation direction and number of rotations of the output shaft of the motor 33. The motor 33 serves as a power source, driving the second driving arms 37 on both sides of the end of the connecting assembly 3 to open outward or close inward.

[0033] By adopting the above technical solution: A connecting component 3 is added between the hydraulic cylinder assembly 2 and the hammer head 4. The second drive arms 37 on both sides of the end of the connecting component 3 can open outward and close inward under the drive of the motor 33. When the hammer head 4 falls, the connecting component 3 is controlled to disconnect the connection between the hammer head 4 and the hydraulic cylinder assembly 2. When the hammer head 4 falls and strikes the hammer body 5 and the tamping plate 6, the hydraulic cylinder assembly 2 and the hammer head 4 are in a separated state. While not affecting the hammering effect of the hammer head 4, the reaction force transmitted from the hammer head 4 to the hydraulic cylinder assembly 2 is reduced, and the impact force is reduced. This is to protect the hydraulic cylinder assembly 2, prevent fatigue damage, and extend the service life of the compaction equipment. After one compaction action is completed, the connecting component 3 is controlled to reconnect the hammer head 4 and the hydraulic cylinder assembly 2. Under the drive of the hydraulic cylinder assembly 2, the hammer head 4 is raised to a certain height, and the above action is repeated. The ground is compacted by the hammer head 4 repeatedly striking the tamping plate 6.

[0034] Example 2: Based on Example 1, this example introduces the specific structure of the dust suppression component 9 in a road construction compaction device. The dust suppression component 9 includes a dust suppressant storage tank 91 and a spray pipe 92. The spray pipe 92 includes a connecting pipe 97. The dust suppressant storage tank 91 stores dust suppressant, which can quickly capture and firmly adsorb particulate dust, thus having the function of dust suppression and prevention.

[0035] By adding a dust suppression component 9 to the tamping frame 1, dust suppressant can be sprayed onto the ground to suppress dust during the tamping operation. This eliminates the need for dust suppression before the tamping operation, allowing the dust suppression and tamping operations to be carried out simultaneously, thus reducing labor intensity.

[0036] In some examples, a pump body 93 is provided on one side of the dust suppressant storage tank 91. Both the dust suppressant storage tank 91 and the pump body 93 are mounted on the loader 8. One end of the pump body 93 is connected to the dust suppressant storage tank 91 through a liquid extraction pipe 94, and the other end of the pump body 93 is connected to the connecting pipe 97 through a delivery hose 95.

[0037] When the pump body 93 is in operation, it extracts the dust suppressant from the dust suppressant storage tank 91 and sends it to the delivery hose 95. The dust suppressant enters the spray pipe 92 through the delivery hose 95 and is finally sprayed out to the surrounding area through multiple spray nozzles 96 of the spray pipe 92 to suppress dust.

[0038] In some examples, the spray pipe 92 is fixed to the outer surface of the ramming frame 1.

[0039] In some examples, the spray pipe 92 is provided with multiple sets of spray nozzles 96, which are evenly distributed at intervals. The multiple sets of spray nozzles 96 achieve uniform and wide-area spraying of dust suppressant, thereby improving the dust suppression effect.

[0040] A compaction process for a road construction compaction device includes the following steps: Step 1: Install the tamping frame 1 of the compaction equipment on the loader 8, connect the adjustment component 81 of the loader 8, and adjust the working position of the compaction equipment through the adjustment component 81; Step 2: The operator drives the loader 8 to the designated work position, and under the drive of the adjustment component 81, the compaction equipment is erected and the ground is compacted. The lifting seat 41 of the hammer 4 is hung on the connecting shaft 39 of the connecting component 3, and the hammer 4 is lifted under the drive of the hydraulic cylinder component 2. Step 3: After the hydraulic cylinder assembly 2 lifts the hammer head 4 to the specified height, it quickly applies reverse force. Under the combined action of its own weight and the thrust of the hydraulic cylinder assembly 2, the hammer head 4 accelerates to fall. During the fall, the motor 33 of the connecting assembly 3 works, driving the second drive arms 37 on both sides of the end to open outward. The second drive arms 37 drive the connecting shaft 39 on its inner side to move synchronously and open, releasing the hammer head 4 and disconnecting the connection between the hydraulic cylinder assembly 2 and the hammer head 4. The hammer head 4 falls freely. After the hammer head 4 falls, it strikes the lower hammer body 5. The lower hammer body 5 strikes the tamping plate 6, driving the tamping plate 6 pre-pressed on the ground to compact the ground. Step 4: During the compaction operation, the pump body 93 works to extract the dust suppressant from the dust suppressant storage tank 91 and send it to the delivery hose 95. The dust suppressant enters the spray pipe 92 through the delivery hose 95 and is sprayed out to the surrounding area through the multiple spray nozzles 96 of the spray pipe 92 to suppress dust. Step 5: After one compaction action is completed, the hydraulic cylinder assembly 2 drives the connecting assembly 3 to move down to the designated position. The motor 33 of the connecting assembly 3 starts working, and the second drive arms 37 on both sides of the drive end close inward. The second drive arms 37 drive the connecting shaft 39 on their inner side to move synchronously and close. The connecting shaft 39 re-enters the slot 42 of the lifting seat 41, reconnecting the hydraulic cylinder assembly 2 and the hammer head 4. The hammer head 4 is lifted under the drive of the hydraulic cylinder assembly 2. The above action is repeated. The ground is compacted by the hammer head 4 repeatedly hitting the tamping plate 6.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.

5. The road construction compaction equipment according to claim 4, characterized in that: The spray pipe (92) is provided with multiple sets of spray nozzles (96), and the multiple sets of spray nozzles (96) are evenly distributed at intervals.

6. A compaction process for a road construction compaction device, implemented based on the road construction compaction device described in claim 5, characterized in that, Includes the following steps: Step 1: Install the tamping frame (1) of the tamping equipment on the loader (8), connect the adjustment component (81) of the loader (8), and adjust the working position of the tamping equipment through the adjustment component (81); Step 2: The staff drives the loader (8) to the designated work position, and under the drive of the adjustment component (81), the compaction equipment is erected and the ground is compacted. The lifting seat (41) of the hammer (4) is hung on the connecting shaft (39) of the connecting component (3), and the hammer (4) is lifted under the drive of the hydraulic cylinder component (2). Step 3: After the hydraulic cylinder assembly (2) lifts the hammer (4) to the specified height, it quickly reverses the force. The hammer (4) accelerates down under the combined action of its own weight and the thrust of the hydraulic cylinder assembly (2). During the fall, the motor (33) of the connecting assembly (3) works, driving the second drive arms (37) on both sides of the end to open outward. The second drive arms (37) drive the connecting shaft (39) on its inner side to move synchronously and open, releasing the hammer (4) and disconnecting the connection between the hydraulic cylinder assembly (2) and the hammer (4). The hammer (4) falls freely. After the hammer (4) falls, it strikes the lower hammer body (5). The lower hammer body (5) strikes the tamping plate (6), driving the tamping plate (6) pre-pressed on the ground to compact the ground. Step 4: During the compaction operation, the pump body (93) works to extract the dust suppressant from the dust suppressant storage tank (91) and send it to the delivery hose (95). The dust suppressant enters the spray pipe (92) through the delivery hose (95) and is sprayed out to the surrounding area through the multiple spray nozzles (96) of the spray pipe (92) to suppress dust. Step 5: After one compaction action is completed, the hydraulic cylinder assembly (2) drives the connecting assembly (3) to move down to the designated position. The motor (33) of the connecting assembly (3) works, and the second drive arms (37) on both sides of the drive end close inward. The second drive arms (37) drive the connecting shaft (39) on its inner side to move synchronously and close. The connecting shaft (39) re-enters the slot (42) of the lifting seat (41) and reconnects the hydraulic cylinder assembly (2) and the hammer (4). The hammer (4) is lifted under the drive of the hydraulic cylinder assembly (2). The above action is repeated. The ground is compacted by repeatedly pounding the tamping plate (6) with the hammer (4).
