Description

Technical Field

[0001] The utility model relates to the technical field of soft soil foundation construction, in particular to a soft soil foundation compacting device. Background Art

[0002] Soft soil foundation refers to a weak soil layer with low strength and high compression. Due to its low strength and large settlement, soft soil often poses a great threat to road construction. If not handled properly, it will have a significant impact on the construction and use of the highway. Therefore, compaction of soft soil foundation is particularly important.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] In the description of this utility model, unless otherwise expressly specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed or detachable connections, mechanical or electrical connections, direct or indirect connections through an intermediate medium, and internal communication between two components or interaction between two components.

A first feature being "below," "below," and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0033] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0034] Soft soil foundation refers to a weak soil layer with low strength and high compression. Due to its low strength and large settlement, soft soil often poses a great threat to road construction. If not handled properly, it will have a significant impact on the construction and use of the highway. Therefore, compaction of soft soil foundation is particularly important.

[0035] Currently, compaction devices for soft soil foundations rely on manual positioning to move the device to each compaction point. The device then tampers at each compaction point, moves to the next compaction point, and continues tamping. This can lead to missed tamping or repeated tamping, resulting in poor compaction results. Furthermore, after compacting the soft soil foundation with current compaction devices, rolling compaction requires an additional rolling process, which is time-consuming, labor-intensive, and inefficient.

[0036] To solve the above problems, see Figure 1-Figure 4 The utility model proposes a soft soil foundation compaction device for realizing the linkage of walking and compaction, so that the soft soil foundation compaction device can tamp while moving, effectively avoiding the situation of missed tamping and repeated tamping and compaction; at the same time, tamping compaction and rolling compaction can be carried out at the same time, without the need to add an additional rolling compaction process, thereby improving construction efficiency.

[0037] The soft soil foundation compaction device includes a frame 10, a traveling mechanism 20, a compacting mechanism 30, and a rolling mechanism 40. The traveling mechanism 20 is disposed at the bottom of the frame 10 and includes traveling wheels 21 and axles 22, with the traveling wheels 21 fixedly connected to the axles 22. The compacting mechanism 30 includes a compacting member 31 and a transmission assembly 32, with the compacting member 31 being slidably connected to the frame 10. The transmission assembly 32 is in transmission connection with the axles 22 and the compacting member 31. The rotation of the traveling wheels 21 can drive the compacting member 31 to reciprocate in the vertical direction through the transmission assembly 32. The rolling mechanism 40 includes a rolling roller 41 and a lifting assembly 42, which is connected to the frame 10 and can drive the rolling roller 41 to rise and fall in the vertical direction.

[0038] When using the soft soil foundation compaction device, the operator pushes the frame 10 to move forward, and the walking wheels 21 walk on the foundation. The rotation of the walking wheels 21 drives the wheel axle 22 to rotate, and the transmission assembly 32 transmits the connection between the wheel axle 22 and the compaction member 31. The transmission assembly 32 converts the rotational motion of the wheel axle 22 into the translational motion of the compaction member 31. Therefore, the rotation of the walking wheels 21 can drive the compaction member 31 to reciprocate in the vertical direction. The compaction member 31 can tamp the foundation, thereby realizing the linkage between the walking mechanism 20 and the compaction mechanism 30, so that the soft soil foundation compaction device tamps while moving, which can avoid missed tamping and repeated tamping and compaction. The rolling mechanism 40 includes a rolling roller 41 and a lifting assembly 42. The rolling roller 41 is connected to the lifting assembly 42, and the lifting assembly 42 is connected to the frame 10. The lifting assembly 42 can drive the rolling roller 41 to move between the working position and the storage position in the vertical direction. When tamping and rolling compaction need to be carried out simultaneously, the lifting assembly 42 causes the rolling roller 41 to descend to contact the foundation. When the operator pushes the frame 10 forward, the rolling roller 41 rolls on the foundation and then compacts the foundation, achieving tamping compaction and rolling compaction at the same time. There is no need to add an additional rolling compaction process, thereby improving construction efficiency.

[0039] The traveling mechanism 20 supports the vehicle frame 10, which in turn supports the compacting mechanism 30 and the rolling mechanism 40. To enhance the stability of the vehicle frame 10, at least two axles 22 are provided, each of which is equipped with one or two traveling wheels 21, one of which is connected to the transmission assembly 32. Providing at least two axles 22 can better withstand the pressure of the vehicle frame 10 and improve the stability of the vehicle frame 10.

[0040] See also Figure 2 Two axles 22 are provided, each with two running wheels 21. The two axles 22 are spaced apart at the bottom of the frame 10, with the compacting element 31 and the rolling roller 41 located between the two axles 22. Specifically, one axle 22 is located in front of the compacting element 31, the rolling roller 41 is located behind the compacting element 31, and the other axle 22 is located behind the rolling roller 41. The layout of the two axles 22, the compacting element 31, and the rolling roller 41 ensures that both axles 22 are evenly compressed, preventing the soft soil foundation compaction device from tipping forward or backward and improving stability. The two running wheels 21 on each axle 22 can be located at both ends of the axle 22 to improve the stability of the soft soil foundation compaction device during operation.

[0041] The vehicle frame 10 includes a vehicle body 11 and a connecting plate 12 disposed at the bottom of the vehicle body 11. Two connecting plates 12 are spaced apart, corresponding to each wheel axle 22. The wheel axle 22 is rotatably connected to the connecting plates 12. The two running wheels 21 on the wheel axle 22 are distributed on the outer sides of the two connecting plates 12. The connecting plates 12 support the wheel axle 22 and ensure that the wheel axle 22 can rotate. When the running wheels 21 rotate, they drive the wheel axle 22 together. After the transmission assembly 32 transmits the power, the compacting member 31 tamps the foundation.

[0042] The transmission assembly 32 converts the rotation of the running wheel 21 into a reciprocating movement of the compacting member 31 in the vertical direction, so that the running wheel 21 can move on the foundation while the compacting member 31 tampers the foundation. There are many options for the structure of the transmission assembly 32.

[0043] Illustratively, the transmission assembly 32 includes a fixedly connected cam and a camshaft. The compacting member 31 is provided with a cam cavity. The outer circumference of the cam abuts the inner wall of the cam cavity. The camshaft is in transmission connection with the wheel shaft 22. The camshaft is in transmission connection with the wheel shaft 22, which can transmit the rotational torque of the wheel shaft 22 to the camshaft. Because the cam and camshaft are fixedly connected, the camshaft can drive the cam to rotate about its axis. The abutment between the outer circumference of the cam and the inner wall of the cam cavity can achieve vertical movement of the compacting member 31, causing the compacting member 31 to tamp the foundation.

[0044] See also Figure 2 and Figure 4The transmission assembly 32 includes a fixedly connected residual gear 321 and an output shaft 322. The output shaft 322 is drivingly connected to the wheel axle 22 and fixedly connected to the vehicle frame 10. The compacting member 31 includes two racks 311 spaced apart and extending vertically. The residual gear 321 is disposed between the two racks 311 and meshes with at least one of the racks 311. The output shaft 322 is drivingly connected to the wheel axle 22, transmitting the rotational torque of the wheel axle 22 to the output shaft 322. Since the output shaft 322 and the residual gear 321 are fixedly connected, the output shaft 322 can drive the residual gear 321 to rotate together.

[0045] Specifically, the frame 10 also includes two first ribs 13, which are spaced apart on the vehicle body 11 and extend in the vertical direction. The output shaft 322 is rotationally connected to the first ribs 13 and the output shaft 322 is parallel to the wheel axle 22. The residual gear 321 and the output shaft 322 rotate together around the axis of the output shaft 322.

[0046] For ease of description, the two racks 311 are respectively a first rack and a second rack. Figure 4 As shown, the stub gear 321 is meshed with the first rack and does not contact the second rack. The position of the output shaft 322 is fixed. As the stub gear 321 rotates counterclockwise, the first rack moves upward, causing the compacting member 31 to move upward. When the stub gear 321 moves to a position where it disengages from the first rack and engages with the second rack, the stub gear 321 continues to rotate counterclockwise, further driving the second rack downward. The rotation of the stub gear 321 repeats the aforementioned meshing process, causing the compacting member 31 to reciprocate in the vertical direction.

[0047] In this embodiment, the compacting member 31 further includes a connecting portion 312 and a compacting portion 313. The connecting portion 312 is slidably connected to the vehicle frame 10 and is provided with a rack cavity 3121. Two racks 311 are disposed on the inner wall of the rack cavity 3121. The compacting portion 313 is located below the vehicle frame 10 and is used to compact the foundation. The rack cavity 3121 is used to accommodate and protect the remaining gear 321 and rack 311. The rack cavity 3121 also allows for clearance of the output shaft 322, preventing interference between the compacting member 31 and the output shaft 322.

[0048] In other embodiments, the rack 311 may be disposed on the outer surface of the connecting portion 312, as long as the stub gear 321 can mesh with the rack 311 and the output shaft 322 does not interfere with the connecting portion 312 when the rack 311 moves. Specifically, the connecting portion 312 is provided with an escape hole, so that the output shaft 322 remains within the escape hole when the rack 311 moves and does not interfere with the connecting portion 312.

[0049] Exemplarily, the rack cavity 3121 is arranged through the connecting part 312, the two first ribs 13 are distributed on both sides of the connecting part 312, the output shaft 322 passes through the rack cavity 3121 and is rotatably connected to the first rib 13, and a residual gear 321 is fixedly provided on the output shaft 322. The residual gear 321 is located in the rack cavity 3121 and is engaged with the rack 311, ensuring that when the residual gear 321 rotates, it drives the rack 311 to move, thereby driving the connecting part 312 to reciprocate in the vertical direction.

[0050] The sliding connection between the connecting portion 312 and the vehicle frame 10 may or may not include a slider guide mechanism. For example, the vehicle frame 10 further includes a support frame 14, which is vertically fixed to the vehicle body 11. The connecting portion 312 is provided with ribs, and the support frame 14 is provided with grooves. Both the ribs and the grooves extend vertically, and the ribs are inserted into the grooves to achieve a sliding connection between the connecting portion 312 and the support frame 14. This sliding connection method has a simple structure and is easy to assemble.

[0051] The connecting portion 312 and the compacting portion 313 can be integrally formed or detachably connected. For example, the connecting portion 312 and the compacting portion 313 are secured via conventional bolts, ensuring that vertical movement of the connecting portion 312 drives the compacting portion 313, which in turn compacts the foundation. Damage to the connecting portion 312 or the compacting portion 313 facilitates repair and replacement.

[0052] A first plane is provided on one side of the compacting portion 313 close to the foundation. The first plane contacts the soft soil foundation, so that the foundation is more flat after being rammed by the compacting member 31 .

[0053] The output shaft 322 and the wheel shaft 22 are connected by a belt drive or a chain drive. When a belt drive is used, a single-stage belt drive or a multi-stage belt drive can be used between the output shaft 322 and the wheel shaft 22. Figure 1 and Figure 3 A two-stage belt drive is used between the output shaft 322 and the axle 22. The vehicle frame 10 is also provided with a second rib 15. The transmission assembly 32 also includes a first belt 323, a second belt 324, a first pulley 325, a second pulley 326, a third pulley 327, a fourth pulley 328, and an intermediate shaft 329. The intermediate shaft 329 is rotatably connected to the second rib 15. The first pulley 325 is fixedly mounted on the axle 22. The second pulley 326 and the third pulley 327 are fixedly mounted on the intermediate shaft 329. The fourth pulley 328 is fixedly mounted on the output shaft 322. An opening is provided in the vehicle body 11 above the axle 22. The first belt 323 can pass through the opening to connect with the first pulley 325 and the second pulley 326. The second belt 324 is connected with the third pulley 327 and the fourth pulley 328. The two-stage belt drive can improve transmission efficiency and facilitate maintenance.

[0054] The lifting component 42 can drive the rolling roller 41 to rise and fall in the vertical direction. During the process of compacting the foundation by the soft soil foundation compacting device, if the foundation needs to be rolled and compacted, the lifting component 42 drives the rolling roller 41 to descend in the vertical direction, and the rolling roller 41 rolls and compacts the foundation after contacting the foundation; if the foundation does not need to be rolled and compacted, the lifting component 42 drives the rolling roller 41 to rise in the vertical direction, and the rolling roller 41 is stored under the vehicle body 11.

[0055] There are many options for the structure of the lifting component 42. A hydraulic cylinder, a pneumatic cylinder or a hydraulic push rod can be used. As long as the lifting component 42 can drive the rolling roller 41 to move up and down in the vertical direction, it will be fine.

[0056] In this embodiment, see Figure 1 The lifting assembly 42 includes a driving member 421, a supporting member 422 and two connecting rods 423. The supporting member 422 is slidably connected to the frame 10. The crushing roller 41 is rotatably set on the supporting member 422. The two connecting rods 423 are located on the upper side or the lower side of the supporting member 422. One end of the connecting rod 423 is hinged to the supporting member 422. The driving member 421 can drive the two connecting rods 423 to move closer to or away from each other away from one end of the supporting member 422.

[0057] Specifically, the vehicle body 11 is provided with an opening, and the carrier 422 is partially located within the opening and slidably connected to the vehicle body 11, which can be connected using an existing slider guide mechanism. The driving member 421 can drive the ends of the two connecting rods 423 away from the carrier 422 toward or away from each other, causing the carrier 422 to rise or fall vertically. The rolling roller 41 is rotatably arranged with the carrier 422, and the rolling roller 41 can rise or fall vertically with the carrier 422.

[0058] For example, see Figure 1 The connecting rod 423 is located on the lower side of the supporting member 422. The upper end of the connecting rod 423 is hinged to the supporting member 422. The driving member 421 can drive the lower ends of the two connecting rods 423 to move closer to or away from each other. When the driving member 421 can drive the lower ends of the two connecting rods 423 to move away from each other, the supporting member 422 will move downward. When the driving member 421 can drive the lower ends of the two connecting rods 423 to move closer to each other, the supporting member 422 will move upward. Since the rolling roller 41 is rotatably mounted on the supporting member 422, the rolling roller 41 moves along with the supporting member 422 in a direction closer to or away from the foundation to achieve contact with or separation from the foundation. When the soft soil foundation compaction device is moving, the rolling roller 41 rolls and compacts the foundation, making the foundation more flat.

[0059] In other embodiments, the connecting rod 423 is located on the upper side of the supporting member 422, and the lower end of the connecting rod 423 is hinged to the supporting member 422. The driving member 421 can drive the upper ends of the two connecting rods 423 to move closer to or away from each other. When the driving member 421 can drive the upper ends of the two connecting rods 423 to move away from each other, the supporting member 422 will move upward. When the driving member 421 can drive the upper ends of the two connecting rods 423 to move closer to each other, the supporting member 422 will move downward. Since the rolling roller 41 is rotatably mounted on the supporting member 422, the rolling roller 41 moves along with the supporting member 422 in a direction away from or closer to the foundation, thereby achieving contact with or separation from the foundation.

[0060] The driving member 421 that drives the two connecting rods 423 can be a pneumatic cylinder or an electric push rod. In this embodiment, the driving member 421 includes a motor 4211, a screw 4212, and two sliders 4213. The motor 4211 is connected to the screw 4212. The screw 4212 is provided with two sections of thread with opposite rotation directions, each of which is connected to a slider 4213. The end of the connecting rod 423 away from the supporting member 422 is hinged to the slider 4213. When the motor 4211 drives the screw 4212 to rotate clockwise, the two sliders 4213 move away from each other, driving the ends of the two connecting rods 423 connected to the sliders 4213 away from each other. The connecting rod 423 drives the supporting member 422 downward, thereby causing the rolling roller 41 to contact the foundation and roll and compact the foundation. When rolling and crushing is not needed, the motor 4211 drives the screw 4212 to rotate counterclockwise, so that the two sliders 4213 approach each other, the connecting rod 423 drives the supporting member 422 to rise, and the crushing roller 41 moves upward and is stored under the vehicle body 11.

[0061] The support member 422 can be designed in various shapes depending on practical needs, as long as it can be connected to the connecting rod 423 and the rolling roller 41. In this embodiment, the support member 422 includes a fixedly connected top plate 4221 and two side plates 4222. The top plate 4221 is located above the vehicle body 11. One end of the connecting rod 423 is hingedly connected to the top plate 4221. The two side plates 4222 are spaced apart and extend through the vehicle body 11. The rolling roller 41 is located below the vehicle body 11 and rotatably disposed between the two side plates 4222. The hinged connection between the connecting rod 423 and the top plate 4221 can drive the support member 422 to rise and fall vertically. The side plates 4222 extend through the vehicle body 11. The rolling roller 41 is rotatably connected between the side plates 4222 located below the vehicle body 11, ensuring that the rolling roller 41 rises and falls vertically below the foundation and vehicle body 11 to avoid interference.

[0062] The vehicle frame 10 also includes an operating handle 16, which is provided on the vehicle body 11 and is located at the rear end of the vehicle body 11, so that the operator can push the vehicle frame 10 from the rear end of the vehicle frame 10. When the soft soil foundation compacting device is in use, the operator holds the operating handle 16 and pushes the device forward. The running wheel 21 rolls, thereby driving the wheel axle 22 to rotate. The transmission assembly 32 connects the wheel axle 22 and the compacting member 31. The transmission assembly 32 converts the rotational motion of the wheel axle 22 into translational motion of the compacting member 31. The rotation of the running wheel 21 can drive the compacting member 31 to reciprocate in the vertical direction. The compacting member 31 tamps the foundation, realizing the linkage between walking and compacting, so that the soft soil foundation compacting device tamps the foundation while traveling.

[0063] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
