Abstract

The application relates to the technical field of civil engineering, and discloses a ramming device for civil engineering, which comprises a trolley, a supporting cylinder, a circular rack, a ramming hammer, a first bearing with a seat, a first rotating shaft, a straight gear and an incomplete gear. When in use, after the two incomplete gears rotate under the driving of external force, the two straight gears can be driven to rotate when the toothed parts of the two incomplete gears are engaged with the two straight gears. Then, under the meshing action between the teeth and the guiding and supporting action of the supporting cylinder, the two circular racks can drive the ramming hammer to ascend. When the toothed parts of the two incomplete gears are disengaged from the two straight gears, the ramming hammer can drive the two circular racks to descend under the action of gravity and the guiding and supporting action of the supporting cylinder, so that the ground is rammed. In the process of ramming, the incomplete gears and the straight gears do not contact and collide with each other, so that the abrasion and damage can be reduced, and the ramming effect is ensured.

Description

Technical Field

[0001] This application relates to the field of civil engineering technology, for example to a compaction device for civil engineering. Background Technology

[0002] A related technology (publication number: CN222948966U) discloses a device for compacting foundations in civil engineering, including a base plate. A rectangular limiting hole is formed on the upper surface of the base plate, and a compaction block is disposed inside the rectangular limiting hole. A U-shaped lifting plate is fixedly connected to the upper surface of the compaction block. A vertical plate is fixedly connected to the upper surface of the base plate, and two mounting brackets are fixedly connected to the side of the vertical plate. A linkage rod is rotatably connected between the two mounting brackets, and a cam top block is fixedly connected to the surface of the linkage rod, overlapping the lower surface of the lifting plate.

[0003] In implementing the above embodiments, at least the following problems were found in the related technology:

[0004] This device, used for compacting foundations in civil engineering, works by rotating a linkage rod under external force, which in turn drives a cam block to rotate. The cam block then lifts a lifting plate, causing the compaction block to rise. Under gravity, the compaction block falls, compacting the ground. However, significant friction occurs between the cam block and the lifting plate during the lifting process, leading to wear and damage. Furthermore, the lifting plate is prone to colliding with the cam block during its descent, affecting the compaction effect.

[0019] This disclosure provides a compaction device for civil engineering, comprising a trolley, support cylinders, racks, a compaction hammer, a first bearing with a mounting seat, a first rotating shaft, a spur gear, and an incomplete gear. The trolley drives the entire device. Support cylinders are mounted on the top surface of the trolley along its height and on both sides of the trolley along its width. Both support cylinders support slidable racks. Each support cylinder has a notch in its sidewall for the passage of a spur gear. The racks are slidably mounted inside the support cylinders and slidably pass through the top wall of the trolley, sliding along its height. The compaction hammer is mounted at the bottom end of each rack and is used to abut against the ground to compact it. The first bearing with a mounting seat is mounted on the top surface of the trolley and supports the rotatable first rotating shaft. The first rotating shaft, along the width of the trolley, is mounted on the first bearing with a mounting seat and supports the spur gear.

[0038] Combination Figures 1 to 5As shown, this embodiment of the present disclosure provides a compaction device for civil engineering, including a trolley 1, a support cylinder 2, a rack and pinion 3, a compaction hammer 4, a first bearing with a seat 5, a first rotating shaft 6, a spur gear 7, and an incomplete gear 8. The trolley 1 is used to drive the entire device. The support cylinder 2 is installed on the top surface of the trolley 1 along its height direction and on both sides of the trolley 1 along its width direction. Both support cylinders 2 are used to support the slidable rack and pinion 3. Both support cylinders 2 include notches in their side walls, and the spur gear 7 passes through the notches. The rack and pinion 3 are slidably installed inside the support cylinders 2 and slidably pass through the top wall of the trolley 1, and can slide along the height direction of the trolley 1. The compaction hammer 4 is installed at the bottom end of the rack and pinion 3 on both sides and is used to abut against the ground to compact the ground. The first bearing with a seat 5 is installed on the top surface of the trolley 1 and is used to support the rotatable first rotating shaft 6. The first rotating shaft 6, along the width direction of the trolley 1, is mounted on the first seated bearing 5 to support and mount the spur gear 7. The spur gear 7 is mounted on the first rotating shaft 6 and meshes with the two circular gear racks 3 on both sides through notches on both sides, together converting rotational motion into linear motion. The incomplete gears 8 mesh with the two spur gears 7 on both sides, together transmitting driving force. The two incomplete gears 8 are controlled to rotate synchronously, driving the tamping hammer 4 upwards.

[0039] This disclosure provides a compaction device for civil engineering. Two incomplete gears 8 rotate under external force. When the toothed portions of the incomplete gears 8 mesh with the spur gears 7, they drive the spur gears 7 to rotate. Then, under the meshing action of the teeth and the guiding support of the support cylinder 2, the two circular racks 3 drive the compaction hammer 4 to rise. When the toothed portions of the incomplete gears 8 disengage from the spur gears 7, under the action of gravity and the guiding support of the support cylinder 2, the compaction hammer 4 drives the two circular racks 3 to descend, thereby compacting the ground. During the compaction process, there is no contact or collision between the incomplete gears 8 and the spur gears 7, thus reducing wear and damage and ensuring the compaction effect.

[0040] Optionally, the system also includes a second bearing 9 and a second shaft 10. The second bearing 9 is mounted on the top surface of the trolley 1 and supports the rotatable second shaft 10. The second shaft 10 is mounted on the second bearing 9 along the width direction of the trolley 1 and supports the incomplete gears 8 on both sides. Both incomplete gears 8 are mounted on the second shaft 10 and rotate under the drive of the second shaft 10. The second shaft 10 can be rotated in a controlled manner to drive the incomplete gears 8 on both sides to rotate synchronously.

[0041] In this embodiment, after the second rotating shaft 10 rotates under the drive of an external force, it can drive the two incomplete gears 8 on both sides to rotate synchronously. Compared with the method of driving the two incomplete gears 8 to rotate synchronously separately, the number of power sources is reduced.

[0042] Optionally, the system also includes a reducer 11, a third shaft 12, a driving pulley, a driven pulley, and a belt 13. The reducer 11 is mounted on the top surface of the trolley 1, and its output end is distributed along the width direction of the trolley 1, serving to reduce the rotational speed. The third shaft 12, along the width direction of the trolley 1, is connected to the output end of the reducer 11 and supports the driving pulley. The driving pulley is mounted on the third shaft 12 and rotates under its drive. The driven pulley is mounted on the second shaft 10 and drives the second shaft 10 to rotate. The belt 13 is fitted between the driving pulley and the driven pulley to transmit driving force. The input end of the reducer 11 can be controlled to rotate, thereby driving the second shaft 10 to rotate.

[0043] In this embodiment, after the input end of the reducer 11 rotates under the drive of an external force, the output end of the reducer 11 can drive the third shaft 12 to rotate, thereby driving the driving pulley to rotate. Through the belt 13, the driven pulley can be driven to rotate, thereby driving the second shaft 10 to rotate. The design of the reducer 11 can reduce the rotational speed and increase the output torque.

[0044] Optionally, a motor 14 is also included. The motor 14 is mounted on the top surface of the trolley 1, and the rotating end of the motor 14 is connected to the input end of the reducer 11 to provide driving force.

[0045] In this embodiment, the control motor 14 operates, which, through the reducer 11, drives the third rotating shaft 12 to rotate, thereby driving the drive pulley to rotate. The belt 13 then drives the driven pulley to rotate, which in turn drives the second rotating shaft 10 to rotate, ultimately achieving the function of automatically raising the tamping hammer 4.

[0046] Optionally, it also includes a first coupling 15. The first coupling 15 is installed between the rotating end of the motor 14 and the input end of the reducer 11.

[0047] In this embodiment, a first coupling 15 is further included, which is installed between the rotating end of the motor 14 and the input end of the reducer 11. The first coupling 15 is used to transmit torque so that the rotating end of the motor 14 rotates synchronously with the input end of the reducer 11.

[0048] Optionally, a second coupling 16 is also included. The second coupling 16 is installed between the third shaft 12 and the output end of the reducer 11.

[0049] In this embodiment, a second coupling 16 is also included, which is installed between the third shaft 12 and the output end of the reducer 11. The second coupling 16 is used to transmit torque so that the output end of the reducer 11 rotates synchronously with the third shaft 12.

[0050] Optionally, a third mounted bearing 17 is also included. The third mounted bearing 17 is fitted onto the third shaft 12 and mounted on the top surface of the trolley 1.

[0051] In this embodiment, a third bearing 17 with a mounting seat is further included, which is fitted onto the third rotating shaft 12 and mounted on the top surface of the trolley 1. After being mounted on the top surface of the trolley 1, the third bearing 17 is used to support the mounting of the third rotating shaft 12. It bears the axial and radial forces on the third rotating shaft 12 and improves the rotational accuracy of the third rotating shaft 12.

[0052] Optionally, it also includes linear bearings 18. The linear bearings 18 are respectively fitted onto the two side racks 3 and respectively mounted on the two side support cylinders 2.

[0053] In this embodiment, linear bearings 18 are also included, which are respectively fitted onto the two side racks 3 and respectively installed on the two side support cylinders 2. The two side linear bearings 18 are used to reduce the friction between the two side racks 3 and the two side support cylinders 2, and to improve the accuracy of the two side racks 3 sliding relative to the two side support cylinders 2.

[0054] Optionally, a limiting plate 19 is also included. The limiting plate 19 is mounted on the top of the two side toothed racks 3.

[0055] In this embodiment, a limiting plate 19 is also included, which is installed at the top of the two side toothed racks 3. The limiting plate 19 is used to limit the movement of the two side toothed racks 3 to prevent them from falling out of the two side support cylinders 2.

[0056] Optionally, it also includes a spring 20. The spring 20 is respectively fitted onto the two circular toothed racks 3 on both sides, and is located between the tamping hammer 4 and the top wall of the trolley 1.

[0057] In this embodiment, a spring 20 is further included, which is respectively fitted onto the two circular toothed racks 3 on both sides and located between the tamping hammer 4 and the top wall of the trolley 1. The spring 20 is used to provide elastic force. As the tamping hammer 4 rises, the springs 20 on both sides are continuously compressed, thereby storing elastic potential energy. When the tamping hammer falls, it applies a downward force to the tamping hammer 4, thereby increasing the force of the tamping hammer 4 on the ground.
