Abstract
Description
Technical Field
[0001] This utility model relates to the field of road construction technology, and in particular to a road construction foundation compaction device. Background Technology
[0002] The purpose of road compaction is to improve its strength and stability, reduce the permeability of the roadbed, and reduce uneven deformation caused by freezing, thereby ensuring that the road surface has sufficient mechanical strength and stability to resist vehicle loads and extend the service life of the road.
[0003] Chinese utility model patent CN219260644U discloses a compaction device for road construction, belonging to the field of road construction technology. The compaction device includes a body, and further includes: a hammer rod slidably connected to the body; a hammer disc fixedly connected to the hammer rod; a cleaning box fixedly connected to the body; a cleaning rod slidably connected to the cleaning box; and a scraper fixedly connected to the cleaning rod. The scraper is in contact with the bottom wall of the hammer disc. When the hammer disc compacts the ground and retracts, the cleaning rod slides out, causing the scraper to scrape off the soil adhering to the bottom wall of the hammer disc.
[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When the above-mentioned device is used, the hammering disc is driven by a hydraulic press to compact the bottom surface. During this process, the time required for the hydraulic press to retract and extend is relatively long, which makes it impossible to quickly hammer the bottom surface, resulting in poor compaction effect. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a road construction foundation compaction device.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a road construction foundation compaction device, including a body, a groove is provided on the bottom surface of the body, a slide rod is slidably arranged in the groove, a compaction hammer is fixedly arranged on the bottom surface of the slide rod, the compaction hammer is a compaction hammer made of steel, and a drive component for driving the compaction hammer to perform hammering is provided on the body.
[0007] By adopting the above technical solution, when workers need to compact the ground, they need to drive the sliding rod up and down through the drive component, which in turn drives the compaction hammer up and down, so that the compaction hammer can pound the ground and compact it. During this process, the drive component can drive the sliding rod to slide up and down quickly, thereby improving the compaction effect.
[0008] Furthermore, a rotating groove is provided on the side wall of the machine body, and the rotating groove is connected to the sliding groove. The drive assembly includes a motor fixedly mounted on the side wall of the machine body, a rotating component rotatably mounted in the rotating groove, a connecting rod sleeved on the outer wall of the rotating component, and a drive component slidably mounted in the sliding groove. The connecting rod is rotatably connected to the drive component, the connecting rod is fixed to the rotating component, the motor output shaft is fixed to the rotating component, and the sliding rod is fixed to the drive component.
[0009] By adopting the above technical solution, when workers need to compact the ground, they need to start the motor, which will cause the motor output shaft to rotate. This will cause the rotating component to rotate under the action of the motor output shaft, and in turn, the connecting rod will rotate under the action of the rotating component. Since the connecting rod and the rotating component are eccentrically designed, the driving component will slide up or down under the action of the connecting rod, which will cause the sliding rod to slide under the action of the driving component. This will cause the compaction hammer to pound the ground under the action of the sliding rod. During this process, the motor rotates once, and the compaction hammer completes the following up and down sliding, thereby increasing the pounding speed and improving the compaction effect.
[0010] Furthermore, the bottom surface of the machine body has two symmetrical connecting grooves, and a first spring is fixedly installed on the inner top wall of each of the two connecting grooves. The other end of each of the two first springs is fixedly installed on the upper surface of the tamping hammer.
[0011] By adopting the above technical solution, when the tamping hammer slides downward, it strikes the ground under the action of the sliding rod and the first spring. During this process, the first spring improves the hammering effect of the tamping hammer, thereby improving the compaction effect.
[0012] Furthermore, a limiting groove is formed on the inner wall of the slide rail, and a limiting plate is slidably disposed in the limiting groove. The limiting plate is sleeved on the outer wall of the slide rod and fixed to the slide rod.
[0013] By adopting the above technical solution, when the slide bar slides, the limiting plate slides synchronously with the slide bar under the action of the slide bar. During this process, the limiting plate limits the slide bar, thereby reducing the probability that the slide bar will slide out of the groove under the action of inertia, thus improving the stability of the device.
[0014] Furthermore, an installation groove is provided on the inner wall of the rotating groove, and an installation rod is slidably disposed in the installation groove. Multiple fixing grooves are arranged in a circular array on the side wall of the rotating component away from the motor. A fixing plate is fixedly disposed on the side wall of the installation rod close to the rotating component. Multiple fixing blocks are distributed in a circular array on the side wall of the fixing plate away from the installation rod. The fixing blocks match the fixing grooves.
[0015] By adopting the above technical solution, when the operator does not need to use the device, the operator needs to slide the mounting rod towards the fixing groove, thereby causing the fixing plate to slide towards the fixing groove under the action of the mounting rod. This causes the fixing block to slide towards the fixing groove under the action of the fixing plate, and then the fixing block slides into the fixing groove, thereby fixing the rotating part and reducing the probability of the rotating part rotating, thus improving the stability of the device.
[0016] Furthermore, a receiving groove is provided on the inner wall of the mounting groove, and a cylinder is installed in the receiving groove. The piston rod end of the cylinder is fixed to the mounting rod.
[0017] By adopting the above technical solution, when the worker needs to slide the slide bar, the worker needs to activate the cylinder, which in turn causes the installation rod to slide under the action of the cylinder. In this process, the cylinder reduces the difficulty for the worker to slide the installation rod, thereby reducing the difficulty of the worker's work.
[0018] Furthermore, multiple heat dissipation holes are provided through the inner wall of the receiving groove.
[0019] By adopting the above technical solution, the heat dissipation holes reduce the probability of cylinder overheating and damage, thereby extending the service life of the cylinder.
[0020] In summary, this utility model has the following beneficial effects:
[0021] 1. In this application, when workers need to compact the ground, they need to drive the slide bar up and down through the drive component, which in turn drives the compaction hammer to slide up and down, so that the compaction hammer can pound the ground and compact the ground. During this process, the drive component can drive the slide bar to slide up and down quickly, thereby improving the compaction effect.
[0022] 2. In this application, when workers need to compact the ground, they need to start the motor, which causes the motor output shaft to rotate. This causes the rotating component to rotate under the action of the motor output shaft, which in turn causes the connecting rod to rotate under the action of the rotating component. Since the connecting rod and the rotating component are eccentrically designed, the driving component slides up or down under the action of the connecting rod, which causes the sliding rod to slide under the action of the driving component. This causes the compaction hammer to pound the ground under the action of the sliding rod. During this process, the motor rotates once, and the compaction hammer completes the following up and down sliding, thereby increasing the pounding speed and improving the compaction effect.
[0023] 3. In this application, when the tamping hammer slides downward, it strikes the ground under the action of the sliding rod and the first spring. During this process, the first spring improves the hammering effect of the tamping hammer, thereby improving the compaction effect. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0030] like Figure 1-4 As shown in the figure, this application discloses a road construction foundation compaction device, including a body 1, a sliding rod 11, a compaction hammer 12, a drive assembly 3, a first spring 4, a limiting plate 5, a mounting rod 6, a fixing plate 61, and a fixing block 62. A sliding groove 2 is formed on the bottom surface of the body 1. The sliding rod 11 is a round rod structure with a vertical axis, and the sliding rod 11 is slidably disposed within the sliding groove 2. The compaction hammer 12 is fixedly disposed on the bottom surface of the sliding rod 11, and the compaction hammer 12 is made of steel.
[0031] When workers need to compact the ground, they need to drive the slide bar 11 up and down through the drive component 3, which in turn drives the compaction hammer 12 up and down, so that the compaction hammer 12 can pound the ground and compact it. During this process, the drive component 3 can drive the slide bar 11 to slide up and down quickly, thereby improving the compaction effect.
[0032] A rotating groove 21 is formed on the side wall of the machine body 1, and the rotating groove 21 is connected to the sliding groove 2. A drive assembly 3 is set on the machine body 1 and is used to drive the tamping hammer 12 to perform hammering. The drive assembly 3 includes a motor 31, a rotating rod, a connecting rod 33, and a drive component 34. The motor 31 is fixedly set on the side wall of the machine body 1, and its output shaft axis is horizontal. The rotating component 32 is rotatably set in the rotating groove 21, and its axis coincides with the axis of the output shaft of the motor 31. The output shaft of the motor 31 and the rotating component 32 are fixed to each other. The connecting rod 33 is sleeved on the outer wall of the rotating component 32, and the connecting rod 33 and the rotating component 32 are fixed to each other. The connecting rod 33 and the drive component 34 are eccentrically set. The drive component 34 is slidably set in the sliding groove 2. The connecting rod 33 and the drive component 34 are rotatably connected, and the sliding rod 11 and the drive component 34 are fixed to each other.
[0033] When workers need to compact the ground, they need to start the motor 31, which will cause the output shaft of the motor 31 to rotate. This will cause the rotating part 32 to rotate under the action of the output shaft of the motor 31, which in turn will cause the connecting rod 33 to rotate under the action of the rotating part 32. Since the connecting rod 33 and the rotating part 32 are eccentrically designed, the driving part 34 will slide up or down under the action of the connecting rod 33, which will cause the sliding rod 11 to slide under the action of the driving part 34. This will cause the compaction hammer 12 to pound the ground under the action of the sliding rod 11. During this process, the motor 31 rotates once, and the compaction hammer 12 completes the following up and down sliding, thereby increasing the pounding speed and improving the compaction effect.
[0034] To improve the compaction effect, two symmetrical connecting grooves 22 are provided on the bottom surface of the machine body 1. A first spring 4 is fixedly installed on the inner top wall of each connecting groove 22, and the other end of each first spring 4 is fixedly installed on the upper surface of the compaction hammer 12. When the compaction hammer 12 slides downwards, it strikes the ground under the action of the sliding rod 11 and the first springs 4. During this process, the first springs 4 enhance the hammering effect of the compaction hammer 12, thereby improving the compaction effect.
[0035] A limiting groove 23 is provided on the inner wall of the slide 2. The limiting plate 5 is slidably disposed in the limiting groove 23, and its axis coincides with the axis of the slide rod 11. The limiting plate 5 is sleeved on the outer wall of the slide rod 11 and is fixed to the slide rod 11.
[0036] When the slide bar 11 slides, the limiting plate 5 slides synchronously with the slide bar 11 under the action of the slide bar 11. During this process, the limiting plate 5 limits the slide bar 11, thereby reducing the probability that the slide bar 11 will slide out of the slide groove 2 under the action of inertia, thus improving the stability of the device.
[0037] An mounting groove 24 is formed on the inner wall of the rotating groove 21, and multiple fixing grooves 25 are formed in a circular array on the side wall of the rotating component 32 away from the motor 31. The mounting rod 6 is a rectangular rod-shaped structure and is slidably disposed in the mounting groove 24. The fixing plate 61 is a circular plate-shaped structure, and its axis coincides with the axis of the rotating component 32. The fixing plate 61 is fixedly disposed on the side wall of the mounting rod 6 near the rotating component 32. Multiple fixing blocks 62 are provided and distributed in a circular array on the side wall of the fixing plate 61 away from the mounting rod 6. The fixing blocks 62 are matched with the fixing grooves 25.
[0038] When the device is not in use, the operator slides the mounting rod 6 toward the fixing groove 25, thereby causing the fixing plate 61 to slide toward the fixing groove 25 under the action of the mounting rod 6. This causes the fixing block 62 to slide toward the fixing groove 25 under the action of the fixing plate 61, thus allowing the fixing block 62 to slide into the fixing groove 25, thereby fixing the rotating part 32 and reducing the probability of the rotating part 32 rotating, thereby improving the stability of the device.
[0039] To reduce the difficulty of the work for the workers, a receiving groove 26 is provided on the inner wall of the mounting groove 24. A cylinder 7 is installed in the receiving groove 26, and the piston rod end of the cylinder 7 is fixed to the mounting rod 6. When the worker needs to slide the sliding rod 11, the worker needs to activate the cylinder 7, which will cause the mounting rod 6 to slide under the action of the cylinder 7. In this process, the cylinder 7 reduces the difficulty for the worker to slide the mounting rod 6, thereby reducing the difficulty of the worker's work.
[0040] To extend the service life of cylinder 7, multiple heat dissipation holes 8 are provided through the inner wall of the receiving groove 26. The heat dissipation holes 8 reduce the probability of cylinder 7 overheating and causing damage, thereby extending the service life of cylinder 7.
[0041] The working principle of the road construction foundation compaction device in this embodiment is as follows: When the worker needs to compact the ground, the worker needs to start the motor 31, which causes the output shaft of the motor 31 to rotate, thereby causing the rotating part 32 to rotate under the action of the output shaft of the motor 31, which in turn causes the connecting rod 33 to rotate under the action of the rotating part 32. Since the connecting rod 33 and the rotating part 32 are eccentrically designed, the driving part 34 slides up or down under the action of the connecting rod 33, thereby causing the sliding rod 11 to slide under the action of the driving part 34, and thus causing the compaction hammer 12 to pound the ground under the action of the sliding rod 11. During this process, the motor 31 rotates one revolution, and the compaction hammer 12 completes the following up and down sliding, thereby increasing the pounding speed and improving the compaction effect.
[0042] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
