Description

Technical Field

[0001] The present invention relates to a vibroflot structure of a gravel pile driver, belonging to the technical field of vibroflots. Background Art

[0002] Vibroflotation gravel piles refer to the construction technology using the vibration water jet method to form many gravel piles composed of stones in the foundation. The gravel piles and the original foundation soil together form a composite foundation, which can improve the bearing capacity of the foundation, reduce the settlement, increase the foundation stability, and improve the anti-seismic liquefaction ability.

[0003] For example, the Chinese patent document with the publication number CN109853563A discloses a water jet vibroflot, which includes a gravity rod and a vibroflot submersible pump. The vibroflot submersible pump is arranged on the gravity rod, and the vibroflot submersible pump is provided with a cable. An anchor body bayonet is arranged at the bottom of the gravity rod. The vibroflot submersible pump has a water outlet and a water inlet. The water outlet of the vibroflot submersible pump is communicated with the water inlet hole of the gravity rod. A fluid passage is provided in the gravity rod, and the fluid passage is communicated with the water inlet hole. When the water jet vibroflot provided by this patent document is in use, vibration and water supply are realized through the vibroflot submersible pump. The two are combined into one, and water jet and vibration are realized during pile driving, improving the pile driving speed and being more convenient to use. It is suitable for the occasion of underwater pile driving; it can reduce the inclination during work and keep vertical during pile driving.

[0004] However, after the existing vibroflot vibrates to form a pile hole inside the formation, due to the better fluidity of some complex formations, the soil will flow into the gap between the pile hole and the vibroflot, resulting in difficulty for the stones to fall to the bottom of the pile hole when adding stones into the pile hole, and the stones will generate a large impact force during the falling process, which is easy to impact and damage the vibroflot. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a vibroflot structure of a gravel pile driver.

[0006] The present invention is achieved through the following technical solutions:

One end of the feeding cylinder is connected to one end of the vibroflot body. The buffer mechanism is located inside the feeding cylinder and is connected to the end of the feeding cylinder close to the vibroflot body. A plurality of discharge ports are opened on the side wall of the feeding cylinder at a position corresponding to the top of the buffer mechanism.

[0008] One end of the feeding cylinder close to the vibroflot body is sealed, and the other end is open. A plurality of discharge ports are evenly distributed on the feeding cylinder. The buffer mechanism includes a conical seat and several springs. The conical seat is slidably connected to the feeding cylinder. One end of several springs is connected to the large end of the conical seat, and the other end is connected to the end of the feeding cylinder close to the vibroflot body.

[0009] A plurality of mounting grooves are uniformly formed on the conical surface of the conical seat, and a discharging assembly is provided in each mounting groove.

[0010] The discharging assembly includes a motor, a driving synchronous pulley, a driven synchronous pulley and a synchronous belt. The motor is arranged in the mounting groove. The driving synchronous pulley is fixedly sleeved on the driving wheel shaft. One end of the driving wheel shaft is rotatably connected to the side wall of the mounting groove, and the other end is in transmission connection with the output shaft of the motor. The driven synchronous pulley is movably sleeved on the driven wheel shaft, and both ends of the driven wheel shaft are fixedly connected to the side wall of the mounting groove. The driven synchronous pulley is located between the driving synchronous pulley and the large-end end face of the conical seat. One end of the synchronous belt is sleeved on the driving synchronous pulley, and the other end is sleeved on the driven synchronous pulley. A plurality of paddles are provided on the synchronous belt.

[0011] The vibroflot structure further includes a controller and a weighing sensor. The controller is electrically connected to the weighing sensor and the motor. The buffer mechanism is connected to one end of the feeding cylinder close to the vibroflot body through the weighing sensor.

[0012] A stop block is provided at one end of the mounting groove close to the large-end end face of the conical seat.

[0013] Through grooves are formed in the synchronous belt at positions corresponding to the paddles. The paddles are located inside the through grooves. The paddles are annular and made of magnetic material. A plurality of hook pieces are provided on a pair of side walls of the through grooves, and the ends of the hook pieces far from the side walls of the through grooves abut against the paddles. A connecting rod is provided in the through groove, and the connecting rod is located inside the paddle.

[0014] A plurality of connecting grooves are uniformly formed on one end face of the driven synchronous pulley. During the rotation of the driven synchronous pulley and the synchronous belt, the connecting grooves are aligned with the through grooves one by one.

[0015] A magnetic block is fixedly provided on the driven wheel shaft, and the length direction of the magnetic block is arranged along the connection line of the two tangent points of the synchronous belt and the driven synchronous pulley.

[0016] The paddle is made of rubber magnetic material. The paddle includes two bonding pieces, and the two ends of the two bonding pieces are fixedly connected in a one-to-one correspondence. The bending direction of the hook piece points to the outside of the synchronous belt.

[0017] A plurality of groups of convex blocks are provided on the two bonding pieces in a one-to-one correspondence, and the convex blocks are located between the two bonding pieces.

[0018] Elastic pads are provided on the inner wall of the synchronous belt at positions corresponding to the through grooves. The through grooves penetrate through the elastic pads. A water storage cavity is provided in the elastic pads. Guide holes are provided on the synchronous belt, and the guide holes communicate the through grooves and the water storage cavities in the elastic pads.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The stones are smoothly guided to the bottom of the pile hole through the feeding tube to gradually fill the gap between the pile hole and the vibrator body. The impact of the falling stones is reduced or removed through the buffer mechanism to prevent the stones from directly falling and impacting the vibrator body and causing damage to it.

[0021] 2. Use the discharge assembly to guide the stones on the conical seat to the discharge port so that the stones can fall out of the discharge port smoothly.

[0022] 3. During the movement of the pick, the hook piece will crawl on the surface of the pick, thereby scraping off the more stubborn impurities attached to the surface of the pick to ensure the effectiveness of subsequent use of the pick.

[0023] 4. During the sliding process of the pick, the position of a pair of bonding plates close to the connecting rod will be stretched apart by the connecting rod, and then the stretched parts will be re-attached after sliding over the connecting rod. Therefore, the bonding plates will produce a creeping effect when sliding over the connecting rod, promoting the shedding of the mud layer on the surface of the pick.

[0024] 5. When a group of protrusions move to the connecting rod, the resistance to the continued sliding of a pair of engaging plates increases. At the moment when the pair of protrusions slide over the connecting rod, the sliding speed of the engaging plates will increase in a short period of time, so that the pick has a frustrating effect when sliding inside the through-slot, further shaking off the mud layer on the surface of the pick.

[0025] 6. After the elastic pad aligned with a certain paddle is squeezed by the driven synchronous pulley, the mud in the water storage chamber is sprayed out through the guide hole to wash the surface of the paddle to prevent mud blocks from adhering to the paddle.

Specific embodiments

[0032] The technical solution of the present invention will be further described below, but the scope of protection claimed is not limited thereto.

[0033] As Figures 1 to 5 shown, a vibroflot structure of a gravel pile driver according to the present invention includes a vibroflot body 1, a feed cylinder 2 and a buffer mechanism. One end of the feed cylinder 2 is connected to one end of the vibroflot body 1. The buffer mechanism is located inside the feed cylinder 2 and is connected to one end of the feed cylinder 2 close to the vibroflot body 1. A plurality of discharge ports 3 are provided on the side wall of the feed cylinder 2 at positions corresponding to the top of the buffer mechanism. During use, a plurality of discharge ports 3 are evenly distributed on the side wall of the feed cylinder 2. The stones are smoothly guided through the feed cylinder 2 to the bottom of the pile hole to gradually fill the gap between the pile hole and the vibroflot body 1. The buffer mechanism reduces or removes the impact of the falling stones, avoiding direct impact of the stones on the vibroflot body 1 and causing damage to it.

[0034] One end of the feed cylinder 2 close to the vibroflot body 1 is sealed, and the other end is open. A plurality of discharge ports 3 are evenly distributed on the feed cylinder 2. The buffer mechanism includes a conical seat 4 and a plurality of springs 5. The conical seat 4 is slidably connected to the feed cylinder 2. One end of the plurality of springs 5 is connected to the large end of the conical seat 4, and the other end is connected to one end of the feed cylinder 2 close to the vibroflot body 1. When the stones fall and impact the conical seat 4, the stones move downward with the conical seat 4 against the spring force of the springs 5, and the springs 5 play a buffering role. The conical surface of the conical seat 4 can guide the stones to fall out from the discharge ports 3.

[0035] A plurality of installation grooves 6 are evenly distributed on the conical surface of the conical seat 4, and a discharging assembly is processed in each installation groove 6. During use, the discharging assemblies in the plurality of installation grooves 6 are aligned with the plurality of discharge ports 3 one by one, and the stones on the conical seat 4 are guided and discharged to the discharge ports 3 through the discharging assemblies, so that the stones can smoothly fall out from the discharge ports 3.

[0036] The discharging assembly includes a motor, a driving synchronous pulley 7, a driven synchronous pulley 21 and a synchronous belt 8. The motor is installed in the installation groove 6. The driving synchronous pulley 7 is fixedly sleeved on the driving wheel shaft, and one end of the driving wheel shaft is rotatably connected to the side wall of the installation groove 6, and the other end is in transmission connection with the output shaft of the motor. The driven synchronous pulley 21 is rotatably sleeved on the driven wheel shaft, and both ends of the driven wheel shaft are fixedly connected to the side wall of the installation groove 6. The driven synchronous pulley 21 is located between the driving synchronous pulley 7 and the large-end end face of the conical seat 4. One end of the synchronous belt 8 is sleeved on the driving synchronous pulley 7, and the other end is sleeved on the driven synchronous pulley 21, and a plurality of paddles 9 are installed on the synchronous belt 8. During use, one side of the synchronous belt 8 is flush with or tangent to the conical surface of the conical seat 4; the motor directly drives the driving wheel shaft to rotate, or drives the driving wheel shaft to rotate through gear transmission or the like. Since the fluidity of some complex strata is good, the external soil will accumulate near the discharge port 3, resulting in a large resistance to the export of the stones at the bottom of the feeding cylinder 2, and it is difficult to smoothly export through the discharge port 3. At this time, the motor is driven to rotate the driving synchronous pulley 7, and then drive the synchronous belt 8 and the driven synchronous pulley 21 to rotate, so that the plurality of paddles 9 move from top to bottom along the conical surface of the conical seat 4, and then the stones are pushed to the outside of the discharge port 3 by the paddles 9, improving the export efficiency of the stones and preventing the stones from being blocked near the discharge port 3.

[0037] The vibroflot structure further includes a controller and a weighing sensor 10. The controller is electrically connected to the weighing sensor 10 and the motor. The buffer mechanism is connected to one end of the feeding cylinder 2 near the vibroflot body 1 through the weighing sensor 10. When there are stones on the conical seat 4, the weight borne by the weighing sensor 10 increases, and relevant signals are transmitted to the controller. The controller starts the motor to drive the driving synchronous pulley 7, the synchronous belt 8 and the driven synchronous pulley 21 to rotate, so as to push the stones on the conical seat 4 to the discharge port 3 by the paddles 9; when there are no stones on the conical seat 4, the weight borne by the weighing sensor 10 decreases, and relevant signals are transmitted to the controller. The controller shuts down the motor, thus realizing the automatic start and stop of the motor.

[0038] A stop block 14 is installed at one end of the installation groove 6 near the large-end end face of the conical seat 4. The stop block 14 seals the gap between the lower end of the installation groove 6 and the synchronous belt 8 to prevent stones from entering the interior of the installation groove 6.

[0039] A through groove 11 is formed in the synchronous belt 8 at a position corresponding to the paddle 9, and the paddle 9 is located inside the through groove 11. The paddle 9 is annular and made of magnetic material. A plurality of hook pieces 18 are installed on both side walls of the through groove 11, and the end of the hook piece 18 far from the side wall of the through groove 11 abuts against the paddle 9. A connecting rod 15 is installed in the through groove 11, and the connecting rod 15 is located inside the paddle 9;

[0040] A plurality of connection grooves 12 are evenly distributed on one end surface of the driven synchronous belt pulley 21, and during the rotation of the driven synchronous belt pulley 21 and the synchronous belt 8, the connection grooves 12 are aligned one by one with the through grooves 11;

[0041] A magnetic block 13 is fixedly mounted on the driven wheel shaft, and the length direction of the magnetic block 13 is arranged along the line connecting the two tangent points of the synchronous belt 8 and the driven synchronous pulley 21 .

[0042] The multiple hook pieces 18 on a pair of side walls of the through groove 11 squeeze the paddle 9 toward the middle, so that the two binding pieces 16 in the paddle 9 are attached together, so that the paddle 9 is in a sheet shape, which is convenient for pushing the stone to the discharge port 3. The friction provided by the hook pieces 18 keeps the paddle 9 at a certain position relative to the through groove 11. During the movement of the paddle 9, the hook pieces 18 will crawl on the surface of the paddle 9, thereby scraping off the stubborn impurities attached to the surface of the paddle 9, ensuring the subsequent use effect of the paddle 9.

[0043] The maximum displacement of the paddle 9 toward the inside and outside of the synchronous belt 8 is limited by the connecting rod 15; in addition, the hydraulic vibrator will form mud inside the pile hole during operation, and the mud will penetrate into the feed tube 2 through the discharge port 3, which will cause the surface of the paddle 9 to be covered with a mud layer. During the sliding process of the paddle 9, the positions close to the connecting rod 15 on a pair of coupling pieces 16 will be stretched apart by the connecting rod 15, and then the stretched parts will be re-attached after sliding over the connecting rod 15. Therefore, the coupling piece 16 will produce a creeping effect when sliding over the connecting rod 15, which will promote the shedding of the mud layer on the surface of the paddle 9 and prevent the mud layer from hardening on the surface of the paddle 9, which will make it difficult for the paddle 9 to slide.

[0044] When a certain paddle 9 moves with the synchronous belt 8 to the upper side of the driven synchronous pulley 21 and is aligned with a certain connecting groove 12 on the driven synchronous pulley 21, the magnetic pole at one end of the paddle 9 close to the driven synchronous pulley 21 is different from the magnetic pole at one end of the magnetic block 13 close to the paddle 9, that is, opposite poles attract each other. Under the action of magnetic force, the paddle 9 overcomes the friction force of the bent hook piece 18 and slides into the connecting groove 12 aligned with it, avoiding interference with the block 14 when the paddle 9 rotates to the block 14; and when the paddle 9 rotates about 180 degrees and is relatively aligned with the other end of the magnetic block 13, the magnetic poles of the ends of the paddle 9 and the magnetic block 13 close to each other are the same, that is, like poles repel each other. Under the action of magnetic force, the paddle 9 overcomes the friction force of the bent hook piece 18 and moves to the outside of the synchronous belt 8, and protrudes from the surface of the synchronous belt 8 again.

[0045] The paddle 9 is made of rubber magnetic material, and includes two connecting pieces 16 , and the two ends of the two connecting pieces 16 are fixedly connected in a one-to-one correspondence, and the bending direction of the hook piece 18 points to the outside of the synchronous belt 8 .

[0046] A plurality of sets of bumps 17 are respectively installed on the two bonding pieces 16 in a one-to-one correspondence, and the bumps 17 are located between the two bonding pieces 16. During the process of the pair of bonding pieces 16 sliding relative to the connecting rod 15, when a set of bumps 17 moves to the position of the connecting rod 15, the resistance of the pair of bonding pieces 16 to continue sliding increases. And at the moment when the pair of bumps 17 slide past the connecting rod 15, the sliding speed of the bonding piece 16 will increase within a short period of time, so that the paddle 9 has a jerky effect when sliding inside the through groove 11, further shaking off the mud layer on the surface of the paddle 9.

[0047] An elastic pad 19 is installed on the inner wall of the synchronous belt 8 at a position corresponding to the through groove 11, and the through groove 11 penetrates through the elastic pad 19. A water storage cavity is provided in the elastic pad 19. The synchronous belt 8 is processed with a guide hole 20, and the guide hole 20 communicates with the through groove 11 and the water storage cavity in the elastic pad 19. During use, the mud entering the feeding cylinder 2 will enter the water storage cavity in the elastic pad 19 through the through groove 11 and the guide hole 20. When a certain paddle 9 slides into the alignment connection groove 12 under the magnetic force of the magnetic block 13, the elastic pad 19 is squeezed by the driven synchronous pulley 21, and the mud in the water storage cavity is ejected through the guide hole 20 to wash the surface of the paddle 9 to prevent the mud layer from adhering to the paddle 9.

[0048] The working principle of the vibroflot structure of the gravel pile machine described in the present invention is as follows:

[0049] After the vibroflot body 1 vibrates to form a pile hole inside the formation, stones are put into the feeding cylinder 2. When the stones fall to the bottom of the feeding cylinder 2, the stones impact the conical seat 4 and follow the conical seat 4 to move downward against the action of the spring 5, and then follow the conical seat 4 to move upward and reset under the action of the spring 5, so as to reduce or unload the impact of the stones through the conical seat 4 and the spring 5. Then the stones roll downward along the conical surface of the conical seat 4 and finally fall out from the discharge port 3 and drop to the bottom of the pile hole to gradually fill the gap between the pile hole and the vibroflot body 1.

[0050] The total weight of the spring 5, the conical seat 4 and the stones on the conical seat 4 is detected by the weighing sensor 10, and the relevant signals are transmitted to the controller in real time. When the total weight increases to a certain value, the controller starts the motor, and the motor drives the driving synchronous pulley 7 to rotate, and drives the synchronous belt 8 and the driven synchronous pulley 21 to rotate, so that the plurality of paddles 9 move from top to bottom along the conical surface of the conical seat 4, and then the stones are dialed outward from the discharge port 3 through the paddles 9 to improve the discharge efficiency of the stones and prevent the stones from being blocked near the discharge port 3. When the total weight decreases to a certain value, the controller shuts down the motor.

[0051] When a certain paddle 9 moves with the synchronous belt 8 to the upper side of the driven synchronous pulley 21 and is aligned with a certain connecting groove 12 on the driven synchronous pulley 21, the magnetic poles of the paddle 9 and the end close to each other on the magnetic block 13 are different. Under the action of magnetic force, the paddle 9 overcomes the friction force of the hook piece 18 and slides into the connecting groove 12 aligned with it, so as to avoid interference with the block 14 when the paddle 9 rotates to the block 14; at the same time, the elastic pad 19 aligned with the paddle 9 is squeezed by the driven synchronous pulley 21, and the mud in the water storage chamber is sprayed out through the guide hole 20 to wash the surface of the paddle 9 and prevent mud from adhering to the paddle 9. When the paddle 9 rotates about 180 degrees and is aligned with the other end of the magnetic block 13, the magnetic poles of the paddle 9 and the end close to each other on the magnetic block 13 are the same. Under the action of magnetic force, the paddle 9 overcomes the friction force of the hook piece 18 and moves to the outside of the synchronous belt 8, and protrudes from the surface of the synchronous belt 8 again.

[0052] When the paddle 9 slides toward the inside or outside of the synchronous belt 8, the position of the pair of binding pieces 16 near the connecting rod 15 will be stretched open by the connecting rod 15, and then the stretched parts will be reattached after sliding over the connecting rod 15, so the binding piece 16 will produce a creeping effect when sliding over the connecting rod 15, promoting the shedding of the mud layer on the surface of the paddle 9. When a group of protrusions 17 move to the connecting rod 15, the resistance of the pair of binding pieces 16 to continue sliding increases, and at the moment when the pair of protrusions 17 slide over the connecting rod 15, the sliding speed of the binding piece 16 will be increased in a short time, so that the paddle 9 has a setback effect when sliding inside the through groove 11, and further shakes off the mud layer on the surface of the paddle 9.
