Description

Technical Field

[0001] The present invention relates to the technical field of compaction equipment, and particularly to a foundation compaction device for construction engineering. Background Art

[0002] In construction engineering, the compaction of the foundation is a key step to ensure the stability of the building. Foundation compaction refers to the process of applying a certain pressure to the foundation during construction, causing changes in the structure of the foundation soil, and thus improving the bearing capacity of the foundation. Foundation compaction is a very important link in the construction process, directly affecting the safety and stability of the building. Traditional foundation compaction methods include using heavy equipment such as rollers and rammer machines for multiple rolling and knocking to achieve the required compaction degree. However, the current foundation compaction equipment cannot compact and consolidate the foundation in contact with the side of the compaction column during foundation compaction. This causes the foundation in contact with the side of the compaction column to be prone to deformation after the compaction column is withdrawn after compaction, thus affecting the foundation compaction effect.

[0089] Reference Figures 1 to 15 The frame 58 is provided with a plurality of evenly distributed cushion blocks 3, an annular plate 4 is fixedly provided at one end of the cushion block 3 away from the frame 58, a fixing plate 5 is fixedly provided inside the frame 58, and a columnar groove 6 penetrating the frame 58 is provided on the fixing plate 5, and further comprising:

[0094] By providing the first ball bearings 20 in this device, the direct contact between the sliding block 59 and the surface of the guide groove 9 is avoided. When the sliding block 59 moves, the frictional force received by the sliding block 59 is converted from sliding friction to rolling friction, thereby greatly reducing the resistance received when the sliding block 59 moves, and improving the compaction effect and compaction efficiency of the compaction column 7 on the foundation to a certain extent.

[0095] Refer to Figures 1 to 15 , an oil delivery part is provided on the compaction column 7, and the oil delivery part includes:

[0098] The connecting pipe 24 is located in the impact groove 10, and the connecting pipe 24 is communicated with the first oil delivery groove 23.

[0099] One end of the compaction column 7 located in the vehicle frame 58 is provided with an impact groove 10, the other end of the compaction column 7 away from the impact groove 10 is provided with an internal groove 11, and the compaction column 7 is provided with a plurality of evenly distributed radiation grooves 12 on the side away from the impact groove 10. A reset groove 60 is opened in the radiation groove 12, and an ignition part electrically connected to the control device 2 is arranged in the impact groove 10. The ignition part includes:

[0100] The piston column 25 is fixedly arranged in the impact groove 10. A second oil delivery groove 26 is opened in the piston column 25, and the second oil delivery groove 26 is communicated with the connecting pipe 24;

[0101] The fuel injector 27 is arranged on the piston column 25 and is electrically connected to the control device 2;

[0103] During operation, the control device 2 controls the one-way valve 28 to open, and the fuel in the fuel tank 21 is sequentially transported to the fuel injector 27 through the first fuel pipeline 23, the connecting pipe 24, the second fuel pipeline 26, and the one-way valve 28, and finally the fuel injector 27 sprays the fuel into the compression space 31.

[0104] The igniter 29 is arranged on the piston column 25 and fixedly connected to the piston column 25. The igniter 29 is electrically connected to the control device 2 and is used to ignite the fuel sprayed by the fuel injector 27.

[0105] Refer to Figures 1 to 15 , there are two sets of blocking parts, and the two sets of blocking parts are symmetrically arranged in the vehicle frame 58. The blocking parts are electrically connected to the control device 2;

[0106] The blocking part includes:

[0108] The driving motor 40 is fixedly arranged on the motor support plate 39 and is electrically connected to the control device 2;

[0109] The driving shaft 41 is rotatably arranged on the motor support plate 39 and is fixedly connected to the output end of the driving motor 40;

[0111] The transmission part is arranged on the fixed plate 5;

[0112] The transmission part includes:

[0113] The sliding groove 43 is opened on the fixed plate 5;

[0114] The sliding backing plate 44 is slidably arranged in the sliding groove 43. A roller groove 45 is opened on the sliding backing plate 44, and a plurality of uniformly distributed load-carrying rollers 46 are arranged in the roller groove 45;

[0115] The transmission toothed plate 47 is fixedly arranged on the surface of the sliding backing plate 44 close to the driving gear 42, and the transmission toothed plate 47 meshes with the driving gear 42.

[0116] The control device 2 controls the driving motor 40 to start, causing the driving shaft 41 fixedly connected to the output end of the driving motor 40 to rotate, thereby driving the driving gear 42 fixedly connected to the driving shaft 41 to rotate. Through the meshing between the driving gear 42 and the transmission toothed plate 47, the sliding cushion plate 44 fixedly connected to the transmission toothed plate 47 is driven to move towards the connecting plate 36 until the load-bearing roller 46 provided on the sliding cushion plate 44 moves directly below the connecting plate 36. Then, the control device 2 controls the first hydraulic telescopic shaft 37 to reset. Under the action of gravity, the counterweight 32 drives the piston cylinder 30 to move towards the piston column 25, so that the second ear plate 33 provided on the piston cylinder 30 drives the guide ring 34 to move towards the piston column 25 until the connecting plate 36 fixedly connected to the guide ring 34 lands on the load-bearing roller 46.

[0117] Referring to Figures 1 to 15 , an impact mechanism is provided on the fixing plate 5 and is electrically connected to the control device 2. The impact mechanism is used to cooperate with the ignition part to push the compaction column 7 to compact the foundation.

[0118] The impact mechanism includes:

[0119] A piston cylinder 30 is located directly above the piston column 25. One end of the piston cylinder 30 close to the piston column 25 is provided with a compression space 31. The axis of the compression space 31 coincides with the axis of the piston column 25, and the diameter of the compression space 31 is equal to the diameter of the piston column 25;

[0120] A counterweight 32 is provided on the piston cylinder 30 and is detachably fixedly connected to the piston cylinder 30. By setting the counterweight 32 and the piston cylinder 30 to be detachably fixedly connected, it enables the staff to adjust and replace the weight of the counterweight 32 according to the compaction requirements of the foundation, thereby improving the applicable range of the device to a certain extent;

[0121] There are multiple second ear plates 33, and the multiple second ear plates 33 are evenly distributed on the surface of the piston cylinder 30. The second ear plates 33 are fixedly connected to the piston cylinder 30;

[0122] A guide ring 34 is fixedly arranged on the second ear plate 33, and the guide ring 34 is slidably connected to the guide rod 19. A plurality of evenly distributed second balls 35 are arranged inside the guide ring 34. The second balls 35 are used to assist the guide ring 34 to slide on the guide rod 19;

[0123] By providing the second ball 35, direct contact between the guide ring 34 and the surface of the guide rod 19 is avoided. When the guide ring 34 moves, the frictional force on the guide ring 34 is converted from sliding friction to rolling friction, thereby greatly reducing the resistance when the guide ring 34 moves, and improving the compaction effect and compaction efficiency of the compaction column 7 on the foundation to a certain extent.

[0124] Connecting plate 36, fixedly arranged on the guide ring 34;

[0125] The first hydraulic telescopic shaft 37 is fixedly arranged on the fixed plate 5 and is electrically connected to the control device 2. The first hydraulic telescopic shaft 37 is located directly below the connecting plate 36, and the first hydraulic telescopic shaft 37 is used to lift the piston cylinder 30;

[0126] The control device 2 controls the first hydraulic telescopic shaft 37 to start. The first hydraulic telescopic shaft 37 continuously extends and pushes the connecting plate 36 to move away from the compaction column 7, thereby causing the guide ring 34 fixedly connected to the connecting plate 36 to move away from the compaction column 7, driving the second ear plate 33 fixedly connected to the guide ring 34 to move away from the compaction column 7, so that the piston cylinder 30 fixedly connected to the second ear plate 33 drives the counterweight 32 to move away from the compaction column 7 until the height of the connecting plate 36 is higher than the height of the carrying roller 46.

[0127] The distance sensor 38 is arranged on the compaction column 7 and is detachably and fixedly connected to the compaction column 7. The distance sensor 38 is electrically connected to the control device 2, and the distance sensor 38 is used to measure the distance between the second ear plate 33 and the compaction column 7 in real time;

[0128] The control device 2 controls the driving motor 40 to start, causing the driving shaft 41 fixedly connected to the output of the driving motor 40 to reverse, thereby driving the driving gear 42 fixedly connected to the driving shaft 41 to reverse. Through the meshing between the driving gear 42 and the transmission toothed plate 47, the sliding cushion plate 44 fixedly connected to the transmission toothed plate 47 is driven to move away from the connecting plate 36 until the carrying roller 46 provided on the sliding cushion plate 44 slides out from below the connecting plate 36. At this time, the connecting plate 36 loses support, and the counterweight 32 and the piston cylinder 30 move towards the piston column 25 under the action of gravity. When the piston column 25 extends into the compression space 31, the air in the compression space 31 is compressed. When the distance between the second ear plate 33 and the compaction column 7 reaches a preset distance threshold (it should be noted that the distance threshold between the second ear plate 33 and the compaction column 7 is set by the staff according to the total weight of the counterweight 32 and the piston cylinder 30), at this time, the control device 2 controls the one-way valve 28 to open, so that the fuel injector 27 sprays fuel into the compression space 31. At the same time, the control device 2 controls the igniter 29 to turn on, thereby igniting the fuel and compressed gas in the compression space 31. At this time, a huge pressure is generated in the compression space 31. The generated pressure on the one hand pushes the piston cylinder 30 away from the compaction column 7, and on the other hand, the generated pressure acts on the piston column 25, so that the piston column 25 exerts a downward pressure on the compaction column 7, and then the compaction column 7 exerts pressure on the foundation, thereby realizing the primary compaction of the foundation. Then, the piston cylinder 30 pushed up by the generated pressure drops again under the action of gravity, and so on, thereby realizing the compaction operation of the foundation.

[0129] A plurality of groups of uniformly distributed third balls 48 are arranged in the columnar groove 6, and the third balls 48 are in rolling connection with the ball groove 8.

[0130] It should be noted that by arranging the third balls 48 in this device, the compaction column 7 is prevented from directly contacting the surface of the columnar groove 6. When the compaction column 7 moves, the frictional force received by the compaction column 7 is changed from sliding friction to rolling friction, thereby greatly reducing the resistance received by the compaction column 7 when moving, and further improving the compaction effect and compaction efficiency of the compaction column 7 on the foundation.

[0131] Refer to Figures 1 to 15 , the connecting spring 13 is fixedly arranged in the built-in groove 11. A radiation block 14 is slidably arranged in the radiation groove 12. One end of the radiation block 14 close to the built-in groove 11 is fixedly provided with a mating block 15. One end of the connecting spring 13 away from the impact groove 10 is fixedly provided with a convex block 16. The convex block 16 is used to cooperate with the mating block 15 to push the radiation block 14 to slide in the radiation groove 12. The radiation block 14 is slidably connected to the radiation groove 12. One end of the radiation block 14 away from the axis of the compaction column 7 is fixedly provided with a consolidation block 17;

[0132] A first reset portion is provided on the radiation block 14, and the first reset portion includes:

[0133] A reset block 61, fixedly arranged on the radiation block 14 and slidably connected with the reset groove 60;

[0134] A reset spring 62, located in the reset groove 60, and one end of the reset spring 62 close to the reset block 61 is fixedly connected with the reset block 61. The initial state of the reset spring 62 is a compressed state.

[0135] When the compaction column 7 compacts the foundation, the boss block 16 arranged in the built-in groove 11 has a tendency to move downward due to its own inertia, and then applies a force to each mating block 15 that cooperates with the boss block 16, so that the radiation block 14 fixedly connected with the mating block 15 applies a force to the consolidation block 17. Thus, when the compaction column 7 compacts the foundation in contact with the end face of the compaction column 7, it can also compact and consolidate the foundation in contact with the side surface of the compaction column 7. When the boss block 16 has an upward movement tendency, at this time, the boss block 16 does not apply a force to each mating block 15 that cooperates with the boss block 16. At this time, the compressed reset spring 62 releases elastic potential energy to push the reset block 61 to slide in the direction of the axis of the boss block 16, so that the radiation block 14 fixedly connected with the reset block 61 slides in the direction of the axis of the boss block 16 until the radiation block 14 is reset, and then prepares for the next compaction and consolidation of the foundation in contact with the side surface of the compaction column 7 by the consolidation block 17. In this way, it cycles repeatedly, and thus completes the compaction of the foundation in contact with the end face of the compaction column 7 and can also compact and consolidate the foundation in contact with the side surface of the compaction column 7, thereby avoiding the deformation of the foundation in contact with the side surface of the compaction column 7 after the compaction column 7 is withdrawn, and thus improving the compaction effect of the device on the foundation to a certain extent.

[0136] A second reset portion is provided in the vehicle frame 58, and the second reset portion includes:

[0137] L-shaped plates 49, having a plurality of them, and the plurality of L-shaped plates 49 are evenly arranged on the compaction column 7, and the L-shaped plates 49 are fixedly connected with the compaction column 7;

[0138] Second hydraulic telescopic shafts 50, having a plurality of them, and the plurality of second hydraulic telescopic shafts 50 are evenly arranged on the fixed plate 5. The second hydraulic telescopic shafts 50 are electrically connected with the control device 2, and the second hydraulic telescopic shafts 50 are located below the L-shaped plates 49.

[0139] The control device 2 controls the second hydraulic telescopic shaft 50 to shorten until the height of the second hydraulic telescopic shaft 50 is contracted to be the same as that of the first hydraulic telescopic shaft 37. At this time, the L-shaped plate 49 loses the support of the second hydraulic telescopic shaft 50, so that the compaction column 7 falls onto the foundation to be compacted under the action of gravity. After the foundation is compacted, the control device 2 controls the second hydraulic telescopic shaft 50 to start, and the second hydraulic telescopic shaft 50 jacks up the compaction column 7 to its original position through the L-shaped plate 49.

[0140] Working principle: Refer to Figures 1 to 15 , during operation, the control device 2 controls the electric roller 57 to start, and at the same time, the construction worker pushes the push handle 1 to move the vehicle frame 58, so as to move the vehicle frame 58 to the foundation to be compacted. Then the control device 2 controls the first hydraulic telescopic shaft 37 to start, and the first hydraulic telescopic shaft 37 continuously extends and pushes the connecting plate 36 to move away from the compaction column 7, so that the guide ring 34 fixedly connected to the connecting plate 36 moves away from the compaction column 7, driving the second ear plate 33 fixedly connected to the guide ring 34 to move away from the compaction column 7, so that the piston cylinder 30 fixedly connected to the second ear plate 33 drives the counterweight 32 to move away from the compaction column 7 until the height of the connecting plate 36 is higher than the height of the load-carrying roller 46;

[0141] Then the control device 2 controls the drive motor 40 to start, so that the drive shaft 41 fixedly connected to the output end of the drive motor 40 rotates, and then drives the drive gear 42 fixedly connected to the drive shaft 41 to rotate. Through the meshing between the drive gear 42 and the transmission tooth plate 47, it drives the sliding cushion plate 44 fixedly connected to the transmission tooth plate 47 to move towards the connecting plate 36 until the load-carrying roller 46 provided on the sliding cushion plate 44 moves to directly below the connecting plate 36. Then the control device 2 controls the first hydraulic telescopic shaft 37 to reset, and the counterweight 32 drives the piston cylinder 30 to move towards the piston column 25 under the action of gravity, so that the second ear plate 33 provided on the piston cylinder 30 drives the guide ring 34 to move towards the piston column 25 until the connecting plate 36 fixedly connected to the guide ring 34 falls on the load-carrying roller 46;

[0142] Then the control device 2 controls the second hydraulic telescopic shaft 50 to shorten until the height of the second hydraulic telescopic shaft 50 is contracted to be the same as that of the first hydraulic telescopic shaft 37. At this time, the L-shaped plate 49 loses the support of the second hydraulic telescopic shaft 50, so that the compaction column 7 falls onto the foundation to be compacted under the action of gravity;

[0143] The control device 2 controls the driving motor 40 to start, causing the driving shaft 41 fixedly connected to the output of the driving motor 40 to reverse, and then driving the driving gear 42 fixedly connected to the driving shaft 41 to reverse. Through the meshing between the driving gear 42 and the transmission toothed plate 47, it drives the sliding cushion plate 44 fixedly connected to the transmission toothed plate 47 to move away from the connecting plate 36 until the carrying roller 46 provided on the sliding cushion plate 44 slides out from below the connecting plate 36. At this time, the connecting plate 36 loses support, and the counterweight 32 and the piston cylinder 30 move towards the piston column 25 under the action of gravity. When the piston column 25 extends into the compression space 31, the air in the compression space 31 is compressed. When the distance between the second ear plate 33 and the compaction column 7 reaches a preset distance threshold, the control device 2 controls the one-way valve 28 to open, so that the fuel injector 27 sprays fuel into the compression space 31. At the same time, the control device 2 controls the igniter 29 to turn on, and then ignites the fuel and compressed gas in the compression space 31. At this time, a huge pressure is generated in the compression space 31. The generated pressure on the one hand pushes the piston cylinder 30 away from the compaction column 7, and on the other hand, the generated pressure acts on the piston column 25, so that the piston column 25 exerts a downward pressure on the compaction column 7, and then the compaction column 7 exerts pressure on the foundation, thus realizing the primary compaction of the foundation. Then, the piston cylinder 30 pushed up by the generated pressure descends again under the action of gravity, and so on, thus realizing the compaction operation of the foundation.

[0144] When the compaction column 7 compacts the foundation, at this time, the boss block 16 provided in the built-in groove 11 has a tendency to move downward due to its own inertia, and then exerts a force on each mating block 15 that cooperates with the boss block 16, so that the radiation block 14 fixedly connected to the mating block 15 exerts a force on the consolidation block 17, thereby compacting and consolidating the foundation in contact with the side surface of the compaction column 7. When the boss block 16 has an upward movement tendency, at this time, the boss block 16 does not exert a force on each mating block 15 that cooperates with the boss block 16. At this time, the compressed return spring 62 releases elastic potential energy to push the return block 61 to slide in the direction of the axis of the boss block 16, so that the radiation block 14 fixedly connected to the return block 61 slides in the direction of the axis of the boss block 16 until the radiation block 14 is reset, and then prepares for the next consolidation block 17 to compact and consolidate the foundation in contact with the side surface of the compaction column 7. By repeating this cycle, while the foundation in contact with the end surface of the compaction column 7 is compacted, the foundation in contact with the side surface of the compaction column 7 can also be compacted and consolidated, thereby avoiding the deformation of the foundation in contact with the side surface of the compaction column 7 after the compaction column 7 is withdrawn, and thus improving the compaction effect of the device on the foundation to a certain extent.

[0145] After the foundation of this area is compacted, the control device 2 is used to control the start of the second hydraulic telescopic shaft 50. The second hydraulic telescopic shaft 50 jacks up the compaction column 7 to its original position through the L-shaped plate 49. Then, the staff uses the control device 2 to control the start of the electric roller 57, so that this device can be moved to the next foundation area to be compacted.
