Description

Technical Field

[0001] The present application relates to the technical field of bored pile construction, and in particular to a pile head concrete backfilling device and method based on vacuum suction. Background Art

[0002] In the field of construction, especially in the construction of bored pile foundations, the quality and integrity of the pile head concrete are crucial to the stability and safety of the overall structure. However, in the actual construction process, due to various reasons, the pile head concrete often has defects, such as voids, bubbles, cracks, etc. These problems not only affect the bearing capacity of the pile, but may also cause safety hazards. Traditional methods of pile head concrete backfilling mostly use manual filling or mechanical grouting, which have many shortcomings. It is difficult to ensure the uniformity of the filling. With the continuous advancement of construction technology, the demand for bored pile head concrete backfilling equipment is also increasing.

[0003] The existing technology still has the following problems:

[0004] 1. Existing concrete backfilling equipment cannot quantitatively discharge materials and cannot accurately control the discharge amount, which may lead to waste of concrete materials, multiple additions or reductions, thereby increasing construction costs. In addition, during the discharge process, concrete slurry will splash after falling, and concrete splashes will pollute the environment of the construction site, increasing the difficulty and cost of cleaning.

[0005] 2. During the vacuum suction process of existing concrete backfilling equipment, the vacuum pump uses negative pressure to remove air and moisture from the concrete to achieve close bonding inside the concrete, thereby effectively enhancing the density and impermeability of the concrete. When the air and moisture are discharged, part of the concrete is also absorbed, and this part of the concrete cannot be reused, resulting in a waste of resources. Summary of the invention

During the rotation of the second connecting plate 64, the raw materials collected in the first discharge barrel 62 and the second discharge barrel 65 enter the cast-in-place pile to form the pile head.

The bottom end of the second motor 633 is fixedly connected to the connecting frame 637, and the connecting plate 636 is slidably connected to the inner cavity of the second connecting plate 64. The bottom end of the second feeding barrel 65 is flush with the upper surface of the baffle 639. The adjusting mechanism 635 includes a connecting block 6351, and the inner cavity of the connecting block 6351 is rotatably connected to the threaded rod 6352. The lower surface of the connecting block 6351 is slidably connected to the driving block 6353. The driving block 6353 and the threaded rod 6352 are connected by threaded transmission. The outer surface of the driving block 6353 is fixedly installed with a driving rod 6354. The four corners of the connecting block 6351 are fixedly installed with a storage rod 6355. The inner cavity of the storage rod 6355 is slidably connected to the inner cavity of the storage rod 6355. A telescopic rod 6356 is connected, and a lifting block 6357 is fixedly connected to the bottom end of the telescopic rod 6356. A fixing plate 6358 is fixedly installed on the upper surface of the lifting block 6357. A driving groove is provided on the outer surface of the fixing plate 6358. The driving rod 6354 is slidably connected to the driving groove. The bottom end of the first fixing rod 634 is fixedly connected to the connecting block 6351, the two ends of the lifting block 6357 are fixedly connected to the connecting plate 636, the connecting frame 637 is fixedly connected to the connecting block 6351, the lifting block 6357 is fixedly connected to the first connecting rod 638, and the second motor 633 adopts a stepping motor. When unloading, the work of the second motor 633 drives the belt 632 to rotate, and the rotation of the belt 632 drives the rotating sleeve 631 to rotate, and the rotation of the rotating sleeve 631 The rotation of the first connecting plate 61 drives the first discharge barrel 62 to rotate, the rotation of the first discharge barrel 62 drives the second discharge barrel 65 to rotate, and the rotation of the second discharge barrel 65 drives the second connecting plate 64 to rotate, so that the first discharge barrel 62 and the second discharge barrel 65 are directly below the discharge port 8, so that the raw materials in the inner cavity of the mixing barrel 1 enter the inner cavities of the first discharge barrel 62 and the second discharge barrel 65, and the inner cavities of the first discharge barrel 62 and the second discharge barrel 65 have fixed capacities to achieve quantitative discharge, and when feeding, the baffle 639 blocks the bottom end of the second discharge barrel 65 to prevent leakage of raw materials during quantitative discharge, thereby ensuring the accuracy of discharge. When the capacity of the first discharge barrel 62 and the second discharge barrel 65 needs to be adjusted,By rotating the threaded rod 6352, the driving block 6353 is made to slide on the connecting block 6351, and the sliding of the driving block 6353 drives the driving rod 6354 to slide in the driving groove on the fixing plate 6358, and the movement of the driving rod 6354 drives the telescopic rod 6356 to slide in the inner cavity of the storage rod 6355. At this time, the distance between the lifting block 6357 and the connecting block 6351 changes, and the movement of the lifting block 6357 drives the connecting plate 636 to move, and the movement of the connecting plate 636 drives the second connecting plate 64 to move, thereby driving the second discharge barrel 65 to slide on the outer surface of the first discharge barrel 62. At this time, the capacity of the first discharge barrel 62 and the second discharge barrel 65 changes, and the amount of quantitative discharge can be adjusted according to demand. The movement of 357 drives the first connecting rod 638 to move, and the movement of the first connecting rod 638 drives the baffle 639 to move, so that the baffle 639 always remains flush with the bottom end of the second discharge barrel 65, so that when the mixing barrel 1 adds materials to the inner cavities of the first discharge barrel 62 and the second discharge barrel 65, the baffle 639 can keep covering the bottom end of the second discharge barrel 65, and as the second connecting plate 64 rotates, the bottom end of the second discharge barrel 65 is exposed, and at this time, the raw materials in the inner cavities of the first discharge barrel 62 and the second discharge barrel 65 fall on the buffer mechanism 66 for buffering, thereby achieving precise control of the raw materials and ensuring that the amount of each discharge meets the preset standard, thereby reducing the multiple additions or reductions due to inaccurate raw materials during discharge.

[0043] See also Figure 3 , Figure 7 and Figure 8As shown, the buffer mechanism 66 includes a first fixing ring 661, the first fixing ring 661 is fixedly connected to the lower end of the second lower barrel 65, the inner cavity of the first fixing ring 661 is slidably connected to the first sliding rod 662, the bottom end of the first sliding rod 662 is fixedly connected to the hopper 663, the top of the first sliding rod 662 is fixedly connected to the connecting head 664, the outer surface of the first sliding rod 662 is sleeved with a first spring 665, the first spring 665 is located between the connecting head 664 and the first fixing ring 661, a groove 666 is provided on one side of the second lower barrel 65 close to the first sliding rod 662, the inner cavity of the connecting head 664 is slidably connected to the elastic rod 667, and the connecting head 664 is fixedly connected to the hopper 663. The inner cavity of 64 is provided with a second spring 668, and the elastic rod 667 and the second spring 668 are elastically connected. The hopper 663 is located directly below the second lower barrel 65. At the same time, the diameter of the hopper 663 is smaller than the diameter of the second lower barrel 65, so that the concrete slurry on the inner wall of the second lower barrel 65 can adhere to the outer surface of the hopper 663 when the material is discharged, so that the hopper 663 shakes, and the end of the elastic rod 667 away from the connecting head 664 fits into the groove 666. With the rotation of the first connecting plate 61 and the second connecting plate 64, the bottom end of the second lower barrel 65 is separated from the contact with the baffle 639. At this time, the raw material flows from the inner cavity of the second lower barrel 65 into the hopper 663. The contact between the concrete slurry and the hopper 663 will increase the weight of the hopper 663. At the same time, the concrete slurry on the hopper 663 enters the cast-in-place pile, which reduces the weight of the hopper 663. At this time, the hopper 663 drives the first slide bar 662 to slide on the first fixed ring 661 to compress the first spring 665, so that the hopper 663 shakes, which reduces the splashing of the concrete slurry when it falls directly, avoids pollution of the environment on the construction site, reduces the difficulty and cost of cleaning, and at the same time, the first slide bar 662 slides in the inner cavity of the first fixed ring 661 to drive the connector 664 to move, and the movement of the connector 664 drives the elastic rod 667 on the groove 666. Move, due to the elastic force of the second spring 668, the elastic rod 667 can be extended and retracted to knock on the groove 666, so that in the process of the raw material of the second discharge barrel 65 falling into the hopper 663, the elastic rod 667 has a knocking effect on the groove 666 under the elastic force of the second spring 668, thereby producing a knocking effect on the second discharge barrel 65, so that the concrete slurry attached to the inner walls of the first discharge barrel 62 and the second discharge barrel 65 all fall into the hopper 663, that is, the slurry falling from the inner cavity of the first discharge barrel 62 and the second discharge barrel 65 can drive the hopper 663 to shake and the elastic rod 667 knocks on the second discharge barrel 65, thereby ensuring the accuracy of quantitative discharge.

There are two shielding pieces 78, and both ends of the push rod 79 are fixedly connected to the shielding piece 78. A piston rod is provided in the inner cavity of the cylinder 76, and the piston rod is fixedly connected to the shielding piece 78. The shielding piece 78 and the inner wall of the connecting pipe 77 are tightly fitted. Water outlets are provided at both ends of the recovery box 71, and the water outlets are located above the filter screen 73. A block is provided on the inner wall of the recovery box 71, and the filter screen 73 is located at The upper surface of the block drives the conduit to remove air and moisture in the cast-in-place pile concrete through the operation of the vacuum pump 72, so that the moisture and part of the concrete enter the inner cavity of the recovery box 71. As the moisture and raw materials in the inner cavity of the recovery box 71 increase, water passes through the filter screen 73 and enters the water storage mechanism 75 through the water outlet. The increase of the material in the inner cavity of the recovery box 71 drives the filter screen 73 to squeeze the control mechanism 74. At this time, the control mechanism 74 drives the cylinder 76 to work so that the piston rod pushes the shielding piece 78, and the shielding piece 78 pushes the push rod 79 and the shielding piece 78 on the inner wall of the connecting pipe 77 to push the concrete in the inner cavity of the recovery box 71 into the inner cavity of the mixing barrel 1 for secondary utilization. When the cylinder 76 is not pushed, one of the shielding pieces 78 is located on the inner wall of the connecting pipe 77 to prevent the concrete in the inner cavity of the recovery box 71 from communicating with moisture and air to enter the inner cavity of the mixing barrel 1. In this way, it is ensured that the recycled concrete entering the inner cavity of the mixing barrel 1 can be reused, thereby achieving the effect of saving raw materials.

Pressing the first button 7411 controls the cylinder 76 to work. When the space of the recovery box 71 expands, that is, the concrete in the inner cavity of the recovery box 71 increases, the filter screen 73 is squeezed at this time, and the filter screen 73 will not exceed the water outlet when moving. , to prevent concrete slurry from flowing out of the water outlet, the filter screen 73 drives the pressure plate 746 to move, the movement of the pressure plate 746 drives the connecting bar 745 to rotate, the rotation of the connecting bar 745 drives the slide 743 to slide on the second fixed rod 742, so that the slide 743 squeezes the third spring 744, and at the same time, the movement of the pressure plate 746 drives the second connecting rod 747 to move, the movement of the second connecting rod 747 drives the pressure plate 748 to move, and the movement of the pressure plate 748 drives the pressure plate 748 to squeeze the first button 7411 on the second fixing ring 7410.

[0046] See also Fig.10 and Fig.12As shown, the water storage mechanism 75 includes a water storage box 751, and second sliding rods 752 are slidably connected to both ends of the water storage box 751. The outer surface of the second sliding rod 752 is sleeved with a fourth spring 753. The bottom end of the second sliding rod 752 is fixedly connected to a support plate 754. The fourth spring 753 is located between the water storage box 751 and the support plate 754. A speaker 755 is fixedly installed on the lower surface of the support plate 754. A second button 756 is provided on the upper surface of the support plate 754. The second button 756 and the speaker 755 are electrically connected. Pressing the second button 756 controls the speaker 755 to sound an alarm. The water storage box 751 is slidably connected to the recovery box 71, and the support plate 754 is fixedly connected to the recovery box 71. During the vacuum water absorption process of the concrete, the vacuum pump 72 removes air and moisture in the concrete to achieve close bonding inside the concrete, thereby effectively enhancing the compactness and impermeability of the concrete. At this time, the water absorbed in the inner cavity of the recovery box 71 The moisture and concrete are settled in the inner cavity of the recovery box 71, part of the moisture is mixed in the concrete, and the excess moisture is filtered through the filter screen 73. When the filter screen 73 is selected for filtration, it is ensured that the concrete slurry will not pass through the aperture of the filter screen 73. At this time, there is excess water above the filter screen 73. At this time, the water enters the inner cavity of the water storage box 751 through the water outlet. The increase in the weight of the water storage box 751 drives the water storage box 751 to slide up and down on the second slide bar 752. The downward movement of the water storage box 751 drives the fourth spring 753 to be compressed. At this time, the bottom end of the water storage box 751 squeezes the second button 756, causing the speaker 755 to sound an alarm, thereby reminding the staff that the water in the inner cavity of the water storage box 751 is too much and needs to be removed to prevent excess water from polluting the environment. Cooperating with the blanking component 6, the number of times raw materials are added and subtracted during the production of cast-in-place piles is reduced, thereby improving construction efficiency and automation level, saving raw materials and reducing costs, simplifying operating procedures and reducing labor intensity.

[0047] In summary, the stirring frame 4 is driven by the operation of the first motor 5 to stir and mix the slurry, the material is discharged through the discharge component 6, and the material is vacuum-drawn through the recovery component 7. By removing the air and moisture in the pile head concrete, the close combination of the concrete inside is achieved, thereby effectively enhancing the compactness and anti-seepage performance of the concrete. Quantitative discharge is carried out through the discharge component 6, that is, the first connecting plate 61 is driven to rotate on the lower surface of the mixing barrel 1 through the regulating mechanism 63, and the first discharge barrel 62 and the discharge port 8 are driven to align, so that the raw materials in the inner cavity of the mixing barrel 1 enter the first discharge barrel 62 and the second discharge barrel 65. During the rotation of the second connecting plate 64, the raw materials collected in the first discharge barrel 62 and the second discharge barrel 65 enter the cast-in-place pile to form the pile head. The buffer mechanism 66 is used for buffering when the concrete falls to prevent the raw materials from splashing. At the same time, the concrete attached to the inner walls of the first discharge barrel 62 and the second discharge barrel 65 is vibrated and dropped to ensure the accuracy of quantitative discharge. At the same time, the regulating mechanism 63 can adjust the amount of quantitative discharge. The control mechanism 74 is squeezed by the filter screen 73. The filter screen 73 is used to squeeze the control mechanism 74. At this time, the control mechanism 74 drives the cylinder 76 to work so that the piston rod pushes the shielding piece 78. The shielding piece 78 pushes the push rod 79 and the shielding piece 78 on the inner wall of the connecting pipe 77 to push the concrete in the inner cavity of the recovery box 71 into the inner cavity of the mixing barrel 1 for secondary utilization. When the cylinder 76 is not pushed, one of the shielding pieces 78 is located on the inner wall of the connecting pipe 77 to prevent the concrete in the inner cavity of the recovery box 71 from communicating with the moisture and air and entering the inner cavity of the mixing barrel 1. In this way, the recycled concrete entering the inner cavity of the mixing barrel 1 can be reused, thereby achieving the effect of saving raw materials.
