Description

Technical Field

[0001] The present invention belongs to the technical field of foundation ramming, and specifically refers to a foundation ramming device for water conservancy projects. Background Art

[0002] Generally, slopes are provided on both sides of the ditch. The height of the slope is related to the depth of the ditch. For the ditch, both the slope and the bottom have certain strength requirements. In many cases, the slope also needs to be cast with concrete; therefore, when building the ditch, it is necessary to ram the slope surface; the ramming of the inclined surface is more difficult than that of the flat surface. Since there is a process of springback during ramming, ordinary rammers can hardly operate on the inclined surface. Currently, most practices are to roll by a solid wheel; but on the one hand, due to the lack of impact, the rolling effect is far less than that of ramming; and since there is an angle between the direction of gravity and the slope surface during rolling, when the weight of the roller is too large, it is easy to cause the collapse of the unrammed slope surface.

[0003] Previously, most ramming devices were driven by diesel; but currently, the proportion of electric drive devices has a tendency to increase; due to the difficulty of obtaining electricity outdoors, the importance of the energy consumption of the device has also become prominent. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a continuous ramming device with an impact force perpendicular to the slope surface; the present invention can reduce the motor power requirement through the accumulation and concentrated release of gravitational potential energy, thereby achieving the goals of energy conservation and improving the device integration; and further reducing the production cost and the use cost.

[0005] To achieve this goal, the present invention proposes a method of rotating an eccentric pendulum by a crankshaft. During the process of the inclined sliding bracket descending along the slope, gravitational potential energy is accumulated by lifting the eccentric pendulum. During this process, since not much work is done against gravity, the energy consumption is not large. However, by concentrating the release of the accumulated gravitational potential energy, a better ramming effect can be achieved; through this solution, if the motor power remains unchanged, a greater ramming force can be generated. If the ramming requirement remains unchanged, a smaller specification motor and supporting components can be used; thus achieving the technical goal of energy conservation and cost reduction.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a foundation ramming device for water conservancy projects, including a pendulum energy storage and release mechanism, a reciprocating ramming mechanism, a self-locking and horizontal movement mechanism, and a slope rolling assembly. The pendulum energy storage and release mechanism moves along the slope rolling assembly. The slope rolling assembly is arranged on the self-locking and horizontal movement mechanism. The reciprocating ramming mechanism is arranged on the pendulum energy storage and release mechanism.

[0007] The pendulum energy storage and release mechanism includes an inclined sliding component, an eccentric energy storage component, a pawl component, and a driving component. The inclined sliding component moves along the slope rolling component. The eccentric energy storage component is rotatably arranged in the inclined sliding component. The pawl components are symmetrically arranged at both ends of the eccentric energy storage component. The driving components are symmetrically arranged on the inclined sliding component.

[0008] During the energy storage process when the inclined sliding bracket slides obliquely downward, the center of gravity positions of the eccentric pendulum and the reciprocating ramming mechanism will both be lifted relative to the inclined sliding bracket, thereby retaining and accumulating the gravitational potential energy of the two. When released, this part of the gravitational potential energy is quickly released and used for ramming, which can greatly reduce the energy consumption of the motor, playing the role of energy saving, cost reduction, and optimizing the equipment volume.

[0009] Further, the inclined sliding component includes an inclined sliding module, an inclined sliding bracket, side panels, and bearings. The inclined sliding module is arranged on the inclined sliding bracket. The inclined sliding bracket moves along the slope rolling component through the inclined sliding module. The side panels are arranged on the inclined sliding bracket. The bearings are arranged in the side panels.

[0010] Preferably, the eccentric energy storage component includes a crankshaft, an eccentric pendulum, and a ratchet wheel. The crankshaft is symmetrically provided with journal necks and disc parts. An eccentric connecting rod is arranged between the two disc parts. The crankshaft is arranged in the bearing through the journal necks. The eccentric pendulum and the ratchet wheel are symmetrically arranged on the journal necks. The eccentric pendulum and the ratchet wheel are both fixedly connected to the journal necks.

[0011] During the process of the crankshaft descending together with the inclined sliding bracket, it can lift the center of gravity of the eccentric pendulum relative to the crankshaft through its own rotation, thereby keeping the center of gravity height of the eccentric pendulum basically unchanged. Thus, during the downward sliding of the inclined sliding bracket, it can not only move the ramming plate away from the slope surface through lateral movement but also avoid wasting the gravitational potential energy of the reciprocating ramming mechanism and the eccentric pendulum.

[0012] As a further preference of the present invention, the pawl component includes a toothed ring, a mounting ring, a pawl base, a pawl hinge shaft, a hook claw, and a pawl return spring. The toothed ring is rotatably arranged on the ratchet wheel. The mounting ring is fixedly connected to the inner ring of the toothed ring. The pawl base is fixedly connected to the inner wall of the mounting ring. The pawl hinge shaft is arranged on the pawl base. The hook claw is rotatably arranged on the pawl hinge shaft. The hook claw cooperates with the ratchet teeth of the ratchet wheel. The pawl return spring is arranged between the hook claw and the mounting ring.

[0013] As a further preference of the present invention, the driving component includes a roller, a rack, a driving motor, and a driving gear. The roller is rotatably arranged inside the side panel. The rack is located between the roller and the toothed ring. The rack and the toothed ring are in meshing transmission. The driving motor is fixedly connected to the side panel. The driving gear is arranged on the output shaft of the driving motor. The driving gear and the toothed ring are in meshing transmission.

[0014] Through the one-way transmission between the ring gear and the ratchet, the slow rotation of the ring gear during the power accumulation stage can cause the crankshaft to rotate slowly; and when the eccentric pendulum swings rapidly across the apex and descends, the ratchet will not rotate with the ring gear, which allows the gravitational potential energy of the eccentric pendulum and the reciprocating tamping mechanism to be released quickly to achieve tamping, and avoids the problem of the oblique sliding bracket descending at an unsteady speed; and if the eccentric pendulum is to move with the oblique sliding bracket when it descends, then the energy used for tamping will inevitably be partially distributed.

[0015] Furthermore, the reciprocating tamping mechanism includes a tamping guide assembly and a tamping assembly, the tamping guide assembly includes a guide plate, a reciprocating bracket, a force storage spring and a swing rod, the guide plate is fixedly connected to the oblique sliding bracket, the guide plate is symmetrically provided with guide sleeves, the reciprocating bracket is symmetrically provided with guide rods, the guide rods are snap-fitted and slidably arranged in the guide sleeves, the force storage spring is arranged between the guide plate and the reciprocating bracket, one end of the swing rod is hinged to the reciprocating bracket, the other end of the swing rod is hinged to the eccentric connecting rod between the original disk parts, and the tamping assembly is arranged on the reciprocating bracket.

[0016] Through the linkage of the swing rod, the reciprocating bracket can be driven to slide back and forth during the rotation of the eccentric pendulum, thereby achieving the approach and distance between the tamping plate and the slope surface; through the storage spring, elastic force can be accumulated during the storage stage, and this part of the elastic force will serve as a supplement to the gravitational potential energy and be used together for tamping.

[0017] Preferably, the tamping assembly comprises a guide block, a sliding guide seat and a tamping plate, the guide block is fixed to the bottom of the reciprocating bracket, the sliding guide seat is slidably arranged on the guide block, the tamping plate is arranged on the sliding guide seat, and the top of the tamping plate is provided with an upturned portion.

[0018] Furthermore, the self-locking transverse movement mechanism includes a transverse movement component and a self-locking component, and the self-locking component is arranged on the transverse movement component.

[0019] Preferably, the transverse movement assembly comprises a base plate, a transverse sliding module and a slide plate, wherein the transverse sliding module is arranged on the base plate, and the slide plate is arranged on the transverse sliding module, and the slide plate can slide along the base plate.

[0020] As a further preferred embodiment of the present invention, the self-locking assembly includes a push rod, a tooth plate, a locking plate, a guide cylinder and a pull rope. The push rod is hinged on the slide through the bottom, the tooth plate is fixed to the bottom plate, a lifting column is provided on the locking plate, and the locking plate is slidably arranged on the slide through the engagement of the lifting column. A locking spring is provided between the top of the lifting column and the slide, and mutually engaging tooth groove features are provided between the locking plate and the tooth plate. The guide cylinder is provided on the slide, and the pull rope passes through the guide cylinder, and the two ends of the pull rope are respectively provided on the locking plate and the push rod.

[0021] Through the linkage of the pull rope, no matter in which direction the push rod is pushed, the self-locking component will be unlocked first, and after the push stops, the locking plate will return to the locked state under the elastic force of the locking spring.

[0022] Furthermore, the slope rolling assembly includes an inclined frame, a rolling shaft and a rolling cylinder, the two ends of the inclined frame are respectively fixed to the slide plate, the lateral sliding module is arranged on the inclined frame, the rolling cylinder is rotatably arranged on the rolling shaft, and the inclined sliding bracket moves along the inclined frame through the inclined sliding module.

[0023] The beneficial effects achieved by the present invention using the above structure are as follows: (1) During the process of accumulating force when the oblique sliding bracket slides obliquely downward, the center of gravity of the eccentric pendulum and the reciprocating tamping mechanism will be lifted relative to the oblique sliding bracket, thereby retaining and accumulating the gravitational potential energy of the two. When released, this part of the gravitational potential energy is quickly released and used for tamping, which can greatly reduce the energy consumption of the motor and play a role in saving energy, reducing costs and optimizing the size of the equipment.

[0024] (2) When the crankshaft descends along with the oblique sliding bracket, it can raise the center of gravity of the eccentric pendulum relative to the crankshaft through its own rotation, thereby keeping the center of gravity height of the eccentric pendulum basically unchanged; thus, when the oblique sliding bracket slides down, the tamping plate can be moved laterally away from the slope, and the gravitational potential energy of the reciprocating tamping mechanism and the eccentric pendulum can be avoided from being wasted.

[0025] (3) Through the one-way transmission between the ring gear and the ratchet, the slow rotation of the ring gear during the power accumulation stage can cause the crankshaft to rotate slowly; and when the eccentric pendulum passes the apex and swings down rapidly, the ratchet will not rotate with the ring gear. This allows the gravitational potential energy of the eccentric pendulum and the reciprocating tamping mechanism to be released quickly to achieve tamping, and avoids the problem of the oblique sliding bracket descending at an unstable speed. Furthermore, if the eccentric pendulum is to move with the oblique sliding bracket when it descends, the energy used for tamping will inevitably be partially distributed.

[0026] (4) Through the linkage of the swing rod, the reciprocating support can be driven to slide reciprocally during the rotation of the eccentric pendulum, so as to realize the approach and separation between the ramming plate and the slope surface; through the energy storage spring, elastic force can be stored during the energy storage stage, and this part of the elastic force will be used as a supplement to the gravitational potential energy and together for ramming.

[0027] (5) Through the linkage of the pulling rope, no matter which direction the push rod is pushed, the self-locking component will be unlocked first, and after stopping pushing, the locking plate will return to the locked state under the elastic force of the locking spring.

[0034] The slope rolling component 4 includes an inclined frame 52, a rolling shaft 53, and a rolling cylinder 54. The two ends of the inclined frame 52 are respectively fixedly connected to the sliding plates 44. The transverse sliding module 43 is arranged on the inclined frame 52. The rolling cylinder 54 is rotatably arranged on the rolling shaft 53. The inclined sliding bracket 10 moves along the inclined frame 52 through the inclined sliding module 9.

[0035] The self-locking and horizontal movement mechanism 3 includes a horizontal movement component 40 and a self-locking component 41. The self-locking component 41 is arranged on the horizontal movement component 40.

[0036] The horizontal movement component 40 includes a bottom plate 42, a transverse sliding module 43, and a sliding plate 44. The transverse sliding module 43 is arranged on the bottom plate 42. The sliding plate 44 is arranged on the transverse sliding module 43. The sliding plate 44 can slide along the bottom plate 42.

[0037] The self-locking component 41 includes a push rod 45, a toothed plate 46, a locking plate 47, a guide cylinder 48, and a pull rope 49. The push rod 45 is hinged to the sliding plate 44 at the bottom. The toothed plate 46 is fixedly connected to the bottom plate 42. The locking plate 47 is provided with a lifting column 50. The locking plate 47 is slidably engaged with the sliding plate 44 through the lifting column 50. A locking spring 51 is arranged between the top of the lifting column 50 and the sliding plate 44. There are mutually engaged tooth groove features between the locking plate 47 and the toothed plate 46. The guide cylinder 48 is arranged on the sliding plate 44.

[0038] Through the linkage of the pull rope 49, no matter which direction the push rod 45 is pushed, the self-locking component 41 will be unlocked first. After stopping pushing, the locking plate 47 will return to the locked state under the elastic force of the locking spring 51.

[0039] The pendulum energy storage and release mechanism 1 includes an inclined sliding component 5, an eccentric energy storage component 6, a pawl component 7, and a driving component 8. The inclined sliding component 5 moves along the slope rolling component 4. The eccentric energy storage component 6 is rotatably arranged in the inclined sliding component 5. The pawl components 7 are symmetrically arranged at both ends of the eccentric energy storage component 6. The driving components 8 are symmetrically arranged on the inclined sliding component 5.

[0040] During the energy storage process of the inclined sliding support 10 sliding obliquely downward, the center of gravity positions of the eccentric pendulum 14 and the reciprocating ramming mechanism 2 will be lifted relative to the inclined sliding support 10, thereby retaining and accumulating the gravitational potential energy of the two. When released, this part of the gravitational potential energy is quickly released and used for ramming, which can greatly reduce the energy consumption of the motor and play a role in energy conservation, cost reduction, and optimizing the equipment volume.

[0041] The inclined sliding assembly 5 includes an inclined sliding module 9, an inclined sliding support 10, a side panel 11, and a bearing 12. The inclined sliding module 9 is provided on the inclined sliding support 10. The inclined sliding support 10 moves along the slope rolling assembly 4 through the inclined sliding module 9. The side panel 11 is provided on the inclined sliding support 10, and the bearing 12 is provided in the side panel 11.

[0042] The eccentric energy storage assembly 6 includes a crankshaft 13, an eccentric pendulum 14, and a ratchet 15. The crankshaft 13 is symmetrically provided with a journal 26 and a disc portion 27. An eccentric connecting rod is arranged between the two disc portions 27. The crankshaft 13 is provided in the bearing 12 through the journal 26. The eccentric pendulum 14 and the ratchet 15 are symmetrically provided on the journal 26, and both the eccentric pendulum 14 and the ratchet 15 are fixedly connected to the journal 26.

[0043] During the process of the crankshaft 13 descending together with the inclined sliding support 10, it can lift the center of gravity of the eccentric pendulum 14 relative to the crankshaft 13 through its own rotation, and then keep the center of gravity height of the eccentric pendulum 14 basically unchanged. Thus, during the downward sliding of the inclined sliding support 10, it can not only move the ramming plate 36 away from the slope surface through lateral movement, but also avoid wasting the gravitational potential energy of the reciprocating ramming mechanism 2 and the eccentric pendulum 14.

[0044] The pawl assembly 7 includes a toothed ring 16, a mounting ring 17, a pawl base 18, a pawl hinge shaft 19, a hook claw 20, and a pawl return spring 21. The toothed ring 16 is rotatably provided on the ratchet 15. The mounting ring 17 is fixedly connected to the inner ring of the toothed ring 16. The pawl base 18 is fixedly connected to the inner wall of the mounting ring 17. The pawl hinge shaft 19 is provided on the pawl base 18. The hook claw 20 is rotatably provided on the pawl hinge shaft 19. The hook claw 20 cooperates with the ratchet teeth of the ratchet 15. The pawl return spring 21 is arranged between the hook claw 20 and the mounting ring 17.

[0045] The drive assembly 8 includes a roller 22, a rack 23, a drive motor 24, and a drive gear 25. The roller 22 is rotatably provided inside the side panel 11. The rack 23 is located between the roller 22 and the toothed ring 16. The rack 23 and the toothed ring 16 are in meshing transmission. The drive motor 24 is fixedly connected to the side panel 11. The drive gear 25 is provided on the output shaft of the drive motor 24. The drive gear 25 and the toothed ring 16 are in meshing transmission.

[0046] Through the one-way transmission between the ring gear 16 and the ratchet 15, the slow rotation of the ring gear 16 during the power accumulation stage can cause the crankshaft 13 to rotate slowly; and when the eccentric pendulum 14 swings rapidly downward over the apex, the ratchet 15 will not rotate with the ring gear 16, which can allow the gravitational potential energy of the eccentric pendulum 14 and the reciprocating tamping mechanism 2 to be released quickly and achieve tamping, and can also avoid the problem of the oblique sliding bracket 10 descending in an unsteady and unstable speed process; and if the eccentric pendulum 14 is to move with the oblique sliding bracket 10 when descending, then the energy used for tamping will inevitably be partially distributed.

[0047] The reciprocating tamping mechanism 2 includes a tamping guide assembly 28 and a tamping assembly 29. The tamping guide assembly 28 includes a guide plate 30, a reciprocating bracket 31, a force storage spring 32 and a swing rod 33. The guide plate 30 is fixedly connected to the oblique sliding bracket 10. A guide sleeve 37 is symmetrically provided on the guide plate 30. A guide rod 38 is symmetrically provided on the reciprocating bracket 31. The guide rod 38 is symmetrically arranged in the guide sleeve 37 for engagement and sliding. The force storage spring 32 is arranged between the guide plate 30 and the reciprocating bracket 31. One end of the swing rod 33 is hinged to the reciprocating bracket 31. The other end of the swing rod 33 is hinged to the eccentric connecting rod between the original disk parts 27. The tamping assembly 29 is arranged on the reciprocating bracket 31.

[0048] Through the linkage of the swing rod 33, the reciprocating bracket 31 can be driven to slide back and forth during the rotation of the eccentric pendulum 14, so that the tamping plate 36 and the slope surface can move closer and farther away; through the force storage spring 32, elastic force can be accumulated during the force storage stage, and this part of the elastic force will be used together with the gravitational potential energy for tamping.

[0049] The tamping assembly 29 includes a guide block 34, a sliding guide seat 35 and a tamping plate 36. The guide block 34 is fixed to the bottom of the reciprocating bracket 31, the sliding guide seat 35 is slidably arranged on the guide block 34, the tamping plate 36 is arranged on the sliding guide seat 35, and the top of the tamping plate 36 is provided with an upturned portion 39.

[0050] like Figure 12 As shown, the movement trajectory of the ramming plate 36 relative to the slope is roughly as shown in the figure. During the force accumulation stage, the oblique sliding bracket 10 moves obliquely downward, and the reciprocating bracket 31 moves obliquely upward relative to the oblique sliding bracket 10. The longitudinal movements of the two roughly offset each other, and the lateral movements are superimposed on each other. Therefore, the ramming plate 36 is roughly in a transverse state during the force accumulation stage, and moves toward the inclined surface during the ramming stage.

[0051] During specific use, first, the user needs to install this device on the slope to be rammed. One set of self-locking and cross-moving mechanisms 3 is located at the top of the slope, and the other set of self-locking and cross-moving mechanisms 3 is located at the bottom of the slope. The inclined sliding module 9 and the transverse sliding module 43 can select various linear motion guiding forms such as sliding or rolling; the cooperation between the gear ring 16 and the rack 23 can also be replaced with a transmission structure such as a chain depending on the slope height. When it is replaced with a chain, the transmission between the driving motor 24 and the gear ring 16 is also replaced with the corresponding transmission form.

[0052] Embodiment 1: When it is necessary to cross-move this device, only need to push the push rod 45 in the same direction simultaneously up and down at approximately the same speed (or use a rope to tow); No matter which direction the push rod 45 is pushed, the push rod 45 will first change from the vertical state to the inclined state. During this process, the locking plate 47 will rise under the pulling of the pulling rope 49 and separate from the toothed plate 46, thus releasing the locked state; After the cross-movement is completed, only need to remove the traction force on the push rod 45, and the locking plate 47 will reset under the elastic force of the locking spring 51. The locking plate 47 and the toothed plate 46 are mutually locked through the tooth grooves, thus automatically returning to the locked state.

[0053] During the cross-movement process, the slope rolling component 4 will also move horizontally, and drive the pendulum energy storage and release mechanism 1 and the reciprocating ramming mechanism 2 thereon to move horizontally together. At this time, through the rolling of the rolling cylinder 54, it can not only support the inclined frame 52, but also roll the slope once.

[0054] Embodiment 2: When the driving motor 24 drives the pendulum energy storage and release mechanism 1 to descend from the top, the driving motor 24 drives the gear ring 16 to rotate through the driving gear 25, and the gear ring 16 drives the crankshaft 13 to rotate through the hook claw 20. At this time, the center of gravity of the eccentric pendulum 14 is located below the central axis of the crankshaft 13. Therefore, the rotation of the crankshaft 13 will slowly lift the eccentric pendulum 14. Since the crankshaft 13 itself descends along with the inclined sliding bracket 10 during this process, under the superposition of the two movements, the height of the center of gravity of the eccentric pendulum 14 changes little relative to the ground, mainly showing a horizontal movement; When the crankshaft 13 rotates, it will also drive the reciprocating bracket 31 to slide in the guiding sleeve 37 through the swing rod 33. During this process, on the one hand, the sliding of the reciprocating bracket 31 leaves time for the next ramming to accelerate and impact, and on the other hand, the elastic force can be stored by the compression of the energy storage spring 32. The elastic potential energy of the energy storage spring 32 and the gravitational potential energy of the eccentric pendulum 14 are released together for ramming; the elastic potential energy of the energy storage spring 32 is used to supplement the gravitational potential energy of the eccentric pendulum 14 to ensure that a good ramming effect can be achieved.

[0055] During the energy storage phase, the center of gravity of the eccentric pendulum 14 moves from below the crankshaft 13 to above the crankshaft 13. After the eccentric pendulum 14 crosses the apex of the crankshaft 13, the eccentric pendulum 14 will rapidly rotate and descend under the dual action of its own weight and rotational inertia; at this time, the rotation of the ratchet 15 will not drive the gear ring 16 to rotate through the claw 20, and the gear ring 16 still maintains the rotational speed driven by the drive motor 24. When the eccentric pendulum 14 rapidly swings downward, it will drive the reciprocating bracket 31 to ram against the inclined plane. At this time, the rebound and reset of the energy storage spring 32 will increase the ramming speed and impact force.

[0056] When the ramming plate 36 just contacts the slope, the guide block 34 is located at the top of the sliding guide seat 35. Since the ramming plate 36 will contact the slope for a short period of time, during this process, the relative sliding between the guide block 34 and the sliding guide seat 35 allows the oblique sliding bracket 10 to move relative to the slope surface.

[0057] Embodiment 3: When the drive motor 24 drives the pendulum energy storage release mechanism 1 to rise from the bottom, since only one-way transmission is possible between the ratchet 15 and the gear ring 16, the gear ring 16 can drive the pendulum energy storage release mechanism 1 to rise at this time but will not drive the crankshaft 13 to rotate. At this time, the ramming plate 36 contacts and slides on the slope surface, but the downward pressure provided is small. During the upward movement of the oblique sliding bracket 10, the ramming plate 36 will slide along the slope surface, and the floating soil on the slope surface can be leveled and preliminarily pressed through the upturned portion 39, thereby realizing the reset of the pendulum energy storage release mechanism 1 and the preliminary leveling before ramming.

[0058] The actual usage cycle sequence of this device is as follows. During assembly, the oblique sliding bracket 10 is located at the bottom of one end of the slope surface, and then the drive motor 24 is started to move the oblique sliding bracket 10 upward for preliminary leveling; after moving to the top, the drive motor 24 is started in the reverse direction for ramming; then the slide plate 44 is laterally pushed for position movement; then it enters the next cycle.
