Description

Technical Field

[0001] This utility model relates to the field of compaction equipment technology, specifically to a compaction device for bridge and culvert abutments. Background Technology

[0002] Backfill compaction behind bridge and culvert abutments is a crucial step in highway construction, directly impacting roadbed stability. Specifically, it occurs in the transition section between the abutment (the structure supporting both ends of the bridge) and the roadbed, or in the area between the abutment body and the backfill on either side of the culvert opening. These areas exhibit significant stiffness differences between the backfill and the rigid bridge / culvert abutments, leading to uneven settlement and potential vehicle bouncing. Furthermore, due to their proximity to the abutments or culverts, the compacted area is small, making it difficult for large machinery to achieve adequate compaction and increasing the risk of post-construction settlement. Traditional compaction devices often rely on their own weight, resulting in bulky and difficult-to-move equipment, especially challenging to operate on slopes and making it difficult to ensure uniform compaction at the edges. For example, while the roadbed slope compaction device disclosed in Chinese Patent No. CN217758692U reduces soil adhesion through a roller structure, it still suffers from the following problems:

[0003] High dependence on gravity: Existing equipment relies on its own weight for compaction, resulting in large size and heavy weight, making it difficult to adapt to operation in narrow abutment areas; Poor slope adaptability: The slope of the side slope leads to insufficient stability of the equipment, which is prone to slippage or uneven compaction, affecting the density of backfill; Insufficient edge compaction: The compaction dead corners near the abutment need to rely on small tampers for assistance, which is inefficient and prone to local settlement.

[0004] In summary, there is an urgent need for a compaction device for bridge and culvert abutments to solve or at least partially solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a compaction device for bridge and culvert abutments, aiming to solve the problem that existing compaction equipment is too bulky to fully compact the bridge and culvert abutments. The specific technical solution is as follows:

[0006] A compaction device for bridge and culvert abutments includes a frame, a compaction plate, and a vibration generating mechanism. The compaction plate is slidably mounted on the frame along the height direction, and the vibration generating mechanism is mounted on the compaction plate. The vibration generating mechanism includes a drive source, a drive gear, a driven gear, a rotating shaft, and an eccentric wheel. The drive source is mounted on the compaction plate, the rotating shaft is rotatably connected to the compaction plate, the drive gear is coaxially and fixedly connected to the output end of the drive source, the driven gear is coaxially and fixedly connected to the rotating shaft, the drive gear meshes with the driven gear, and the eccentric wheel is eccentrically and fixedly connected to the rotating shaft.

[0007] Furthermore, two eccentric wheels are arranged, one at each end of the rotating shaft.

[0008] Furthermore, the two ends of the compacted plate are bent upwards.

[0009] Furthermore, the compaction device for bridge and culvert abutments also includes a battery, which is mounted on the frame and driven by a motor.

[0010] Furthermore, the compaction device for bridge and culvert abutments also includes a push handle, which is installed on the frame.

[0011] Furthermore, the compaction device for bridge and culvert abutments also includes an elastic support mechanism, with the first end of the elastic support mechanism connected to the frame and the second end of the elastic support mechanism connected to the compaction plate.

[0012] Furthermore, the elastic support mechanism includes four springs, which are respectively arranged at the four corners of the compaction plate. The first end of the spring is fixedly connected to the frame, and the second end of the spring is fixedly connected to the compaction plate.

[0013] Furthermore, the compaction device for bridge and culvert abutments also includes a guide member, which includes a guide rod arranged along the height direction and has a guide hole on the frame; and the first end of the guide rod is fixedly connected to the compaction plate, and the second end of the guide rod extends upward and passes through the guide hole.

[0014] Furthermore, the compaction device for bridge and culvert abutments also includes a traveling mechanism, with four traveling mechanisms arranged at the four corners of the frame. The traveling mechanism includes a traveling wheel, an adjusting rod, and a locking component. The adjusting rod is slidably connected to the frame along the height direction, the traveling wheel is rotatably installed at the bottom of the adjusting rod, and the locking component is installed on the frame to position and lock the adjusting rod.

[0015] Furthermore, the adjusting rod is provided with positioning holes, and multiple positioning holes are spaced apart along the height direction of the adjusting rod; the locking element is a screw, which is threaded onto the frame, and one end of the screw extends into one of the positioning holes.

[0016] The application of the technical solution of this utility model has the following beneficial effects:

[0017] During operation, the drive source operates, and the driving gear rotates the driven gear via the driving gear. The rotation of the driven gear causes the rotating shaft and eccentric wheel to vibrate, which in turn causes the compaction plate to vibrate strongly, compacting the ground. Because the compaction plate generates an upward acceleration relative to the ground during vibration, the reaction force of the compaction plate on the ground is much greater than the force exerted by its own weight on the ground, thus enabling better compaction of the ground fill layer. During the compaction process, the frame of the device is manually pushed and moved. Because the compaction plate vibrates constantly during operation, the friction between the compaction plate and the compacted soil is small, and only a small force is needed to move the device manually.

[0018] During use, the device's small overall size facilitates compaction at the junctions of bridge ends and roadbeds, as well as the junctions of culverts and roadbeds. The actual compaction process involves filling one layer of filler material, compacting it, then filling the next layer, and compacting again, repeating this process until all filler material is used. This step-by-step compaction achieves better compaction results.

[0019] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. These will be described below with reference to...

[0025] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] Example:

[0028] See Figures 1-3 This embodiment provides a compaction device for bridge and culvert abutments, including a frame 1, a compaction plate 2, and a vibration generating mechanism 3. The compaction plate 2 is slidably mounted on the frame 1 along the height direction, and the vibration generating mechanism 3 is mounted on the compaction plate 2. The vibration generating mechanism 3 includes a drive source 31, a drive gear 32, a driven gear 33, a rotating shaft 34, and an eccentric wheel 35. The drive source 31 is mounted on the compaction plate 2, the rotating shaft 34 is rotatably connected to the compaction plate 2, the drive gear 32 is coaxially fixedly connected to the output end of the drive source 31, the driven gear 33 is coaxially fixedly connected to the rotating shaft 34, the drive gear 32 meshes with the driven gear 33, and the eccentric wheel 35 is eccentrically fixedly connected to the rotating shaft 34.

[0029] Specifically, the frame 1 is square, with a through hole in the middle, and the compaction plate 2 is square, slightly larger than the through hole. This arrangement allows the frame 1 to be relatively small, making it easy to move the compaction device manually.

[0030] Understandably, during use, the drive source 31 operates, driving the driven gear 33 to rotate via the driving gear 32. The rotation of the driven gear 33 causes the rotating shaft 34 and eccentric wheel 35 to rotate, generating vibration. This, in turn, causes the compaction plate 2 to vibrate strongly, compacting the ground. Because the compaction plate 2 generates an upward acceleration relative to the ground during vibration, the reaction force of the compaction plate 2 on the ground is much greater than the force exerted by its own weight on the ground, thus enabling better compaction of the ground filling layer. During the compaction process, the frame 1 of the device is manually pushed and moved. Because the compaction plate 2 vibrates constantly during operation, the friction between the compaction plate 2 and the compacted soil is small, requiring only a small force to push or pull the device. It should be noted that because the overall size of the device is small, it is convenient for compacting the junctions between the ends of bridges and the roadbed, as well as the junctions between the sides of culverts and the roadbed. Because the device has a limited compaction depth, in the actual compaction process, it is necessary to fill one layer of filler material and compact it, then fill the next layer of filler material and compact it again, and so on, until all the filler material is laid.

[0031] In a preferred embodiment, two eccentric wheels 35 are arranged, with the two eccentric wheels 35 respectively arranged at both ends of the rotating shaft 34.

[0032] Specifically, the driven gear 33 is arranged in the middle of the rotating shaft 34. It can be seen that by arranging eccentric wheels 35 at both ends of the rotating shaft 34, the device can maintain a stable vibration frequency when vibration occurs, thus improving the vibration compaction effect.

[0033] In a preferred embodiment, the two ends of the compaction plate 2 are bent upwards.

[0034] It can be seen that by bending both ends of the compaction plate 2 upwards, two guide surfaces are formed at the lower ends of the compaction plate 2, which facilitates the guidance of the device during movement and makes it easier to move.

[0035] As a preferred embodiment, the bridge abutment back compaction device also includes a battery 4, which is mounted on the frame 1, and the drive source 31 is a motor.

[0036] It is understood that the motor drives the driving gear 32 to rotate, which in turn drives the driven gear 33, the rotating shaft 34, and the eccentric wheel 35 to rotate, generating vibration. Furthermore, by mounting the electric frequency device on the frame 1, the damage to the electric frequency device caused by vibration is reduced. The motor is powered by the battery 4. In actual use, a switch is installed between the motor and the battery 4 to control the motor's start and stop. It should be noted that in some other embodiments of this application, a controller is also included. The two ends of the controller are connected to the battery 4 and the motor respectively via wires. The controller can not only control the start and stop of the motor, but also adjust the motor speed by setting the controller, thereby controlling the vibration frequency of the compaction plate 2 to achieve different compaction effects.

[0037] As a preferred embodiment, the bridge abutment back compaction device also includes a push handle 5, which is detachably mounted on the frame 1 by bolts.

[0038] It is known that the push handle 5 facilitates the movement of the device by pushing or pulling it. In addition, the push handle 5 is mounted on the frame 1, resulting in less vibration, which is beneficial for operators.

[0039] In a preferred embodiment, the compaction device for the bridge abutment further includes an elastic support mechanism 6. The first end of the elastic support mechanism 6 is connected to the frame 1, and the second end of the elastic support mechanism 6 is connected to the compaction plate 2. Specifically, the elastic support mechanism 6 includes four springs, which are respectively arranged at the four corners of the compaction plate 2. The first end of the spring is fixedly connected to the frame 1, and the second end of the spring is fixedly connected to the compaction plate 2.

[0040] It is known that through the setting of the elastic support mechanism 6, the elastic support mechanism 6 supports the frame 1, and when the compaction plate 2 vibrates, the spring in the elastic support mechanism 6 has a buffering effect, reducing the impact transmitted to the frame 1 when the compaction plate 2 vibrates, so that the weight of the frame 1 presses on the compaction plate 2 while reducing the vibration of the frame 1.

[0041] In a preferred embodiment, the bridge abutment backfill compaction device further includes a guide member 7, which comprises a guide rod arranged along the height direction. A guide hole is provided on the frame 1. The first end of the guide rod is welded and fixedly connected to the compaction plate 2, and the second end of the guide rod extends upward and passes through the guide hole. Specifically, two guide rods are arranged, and an anti-detachment block is provided at the end of the guide rod away from the compaction plate 2. The anti-detachment block is detachably connected to the guide rod by a thread. The guide rod and the guide hole are slidably fitted together. The arrangement of the anti-detachment block prevents the guide rod from detaching from the frame 1.

[0042] It is known that by arranging the guide rod and guide hole, the compaction plate 2 and the guide rod can slide relative to the frame 1 along the height direction, so that the frame 1 remains basically stable when the compaction plate 2 vibrates, preventing the vibration of the compaction plate 2 from being directly transmitted to the frame 1 and causing the frame 1 to vibrate violently.

[0043] As a preferred embodiment, the compaction device for the bridge abutment also includes a traveling mechanism 8, of which four traveling mechanisms 8 are arranged at the four corners of the frame 1. The traveling mechanism 8 includes a traveling wheel 81, an adjusting rod 82, and a locking member 83. The adjusting rod 82 is slidably connected to the frame 1 along the height direction, the traveling wheel 81 is rotatably installed at the bottom end of the adjusting rod 82, and the locking member 83 is installed on the frame 1 to position and lock the adjusting rod 82.

[0044] Specifically, the adjusting rod 82 is provided with positioning holes, and multiple positioning holes are spaced apart along the height direction of the adjusting rod 82; the locking element 83 is a screw, which is threaded onto the frame 1, and one end of the screw extends into one of the positioning holes.

[0045] It can be seen that in the working state, first unlock the locking part 83, that is, unscrew the screw from the positioning hole. At this time, the adjusting rod 82 is unlocked. Move the adjusting rod 82 upward along the height direction of the frame 1, so that the traveling wheel 81 is off the ground. Then turn the screw so that the screw extends into the corresponding new positioning hole for positioning. Adjust the four traveling mechanisms 8 in sequence. At this time, all four traveling wheels 81 are in a suspended state, and the weight of the frame 1 is entirely pressed on the compaction plate 2. Start the motor to start the compaction work. When it is necessary to switch from the working state to the moving state, adjust the screw and the adjusting rod 82, so that the adjusting rod 82 moves downward along the height direction of the frame 1, so that the traveling wheel 81 is supported on the ground. Adjust the four traveling mechanisms 8 in sequence. At this time, the compaction plate 2 is in a suspended state, and the frame 1 is supported by the four traveling mechanisms 8. The operator can move the entire device on the ground by pulling the push handle 5, which facilitates the movement and transfer of the device.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
