Description

Technical Field

[0001] This utility model relates to the field of slag removal technology for cast-in-place piles, and in particular to a slag removal device for cast-in-place piles. Background Technology

[0002] Cast-in-place piles are a type of deep foundation constructed on-site. They are formed by drilling or excavating holes in the ground, inserting a reinforcing cage, and then pouring concrete into the hole. They are widely used in construction projects such as buildings, bridges, and docks. To ensure the construction quality of cast-in-place piles, especially after drilling, it is necessary to use a slag removal device to clean the sediment from the hole to prevent residual sediment from affecting the strength and stability of the pile.

[0003] A search revealed that utility model patent CN216428270U discloses a slag removal device for cast-in-place piles, comprising a conveying pipe with a matching spiral conveying blade inside. A connecting rod is uniformly fixedly connected to the top of the conveying pipe, and a top plate is fixedly connected to the top of the connecting rod. The spiral conveying blade is rotatably connected to the top plate. This application, through the arrangement of the spiral conveying blade, motor, and collection pipe, allows the device to be hoisted to the bottom of the cast-in-place pile hole. The motor can then be started to rotate the spiral conveying blade, which, when rotating, conveys the slag inside the pile hole upwards to the top of the conveying pipe, where it falls between the collection pipe and the conveying pipe and is collected. This effectively cleans the slag inside the pile hole, thereby improving the forming quality of the cast-in-place pile.

[0004] However, this device has significant limitations in practical applications: the spiral conveyor blades can only clean and transport sediment in the area directly below the inlet of the conveying pipe, and cannot effectively clean sediment in the area surrounding the lower end of the pipe at the same time. This cleaning method limits the cleaning range and reduces cleaning efficiency. Utility Model Content

[0035] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0036] Please see Figure 1-11 This utility model provides a slag removal device for cast-in-place piles, including a feeding pipe 1 and an auxiliary slag scraping structure 6 connected to the outer side of its lower end. The upper end of the feeding pipe 1 is fixedly connected to a top plate 2 by multiple sets of support rods 11. A discharge channel 12 is formed between two adjacent sets of support rods 11. A storage cylinder 3 is fixedly connected to the lower surface of the top plate 2. The storage cylinder 3 is located outside the feeding pipe 1. A lower end cover 4 adapted to the outer wall of the feeding pipe 1 is detachably connected to the annular opening at the lower end of the storage cylinder 3. A screw feeder 5 is installed inside the feeding pipe 1. The screw feeder 5 includes a screw shaft 51, a motor 52, and a protective shell 53. The screw shaft 51 is located inside the feeding pipe 1, and the upper end of the screw shaft 51 rotates through the top plate 2. The motor 52 is fixedly installed at the upper end of the top plate 2. The output shaft of the motor 52 is fixedly connected to the screw shaft 51. A protective shell 53 is fastened to the outer side of the motor 52. The protective shell 53 is fixedly connected to the upper end of the top plate 2.

[0037] The auxiliary scraping structure 6 includes a fixed ring seat 61, a left arc-shaped scraper 62 and a right arc-shaped scraper 63. The fixed ring seat 61 is fixedly sleeved on the outer side of the lower end of the feeding pipe 1. The left arc-shaped scraper 62 is slidably connected to the left side of the lower surface of the fixed ring seat 61, and the right arc-shaped scraper 63 is slidably connected to the right side of the lower surface of the fixed ring seat 61. The fixed ring seat 61 is internally connected to a drive assembly 64 for driving the left arc-shaped scraper 62 and the right arc-shaped scraper 63 to move closer or further away from each other.

[0038] Multiple sets of support members 7 and lifting rings 8 are evenly distributed circumferentially on the upper surface of the top plate 2, and the support members 7 and lifting rings 8 are arranged alternately along the circumferential direction of the top plate 2.

[0039] The working principle of this utility model is as follows: First, the device is hoisted into the grouting pile hole that needs slag removal using the lifting ring 8. Then, multiple sets of support members 7 securely place the device at the upper opening of the grouting pile hole. Next, the screw feeder 5 and the auxiliary slag scraping structure 6 are started simultaneously. The motor 52 of the screw feeder 5 drives the screw shaft 51 to rotate through the output shaft, thereby conveying the sediment at the lower opening of the feeding pipe 1 upwards. After the sediment is conveyed to the top of the feeding pipe 1, it will fall along the discharge channel 12 between the storage cylinder 3 and the feeding pipe 1. At the same time, the drive component 64 in the auxiliary slag scraping structure 6 also drives the left arc-shaped scraper 62 and the right arc-shaped scraper 63 to move closer to each other, thereby scraping the sediment in the outer area of ​​the lower opening of the feeding pipe 1 to the bottom of the feeding pipe 1, facilitating the conveying of sediment by the screw feeder 5. Finally, the sediment is gathered between the feeding pipe 1 and the storage cylinder 3, and the lower end cover 4 can be opened to remove the sediment.

[0040] Furthermore, the lower end cover 4 is movably inserted into the lower annular opening of the storage cylinder 3, and a fixing ring 41 is fixedly connected to the lower end of the lower end cover 4. The fixing ring 41 is threaded onto the outside of the feeding pipe 1, and multiple sets of ear ring seats 42 are fixedly fixed circumferentially at equal intervals on the outside of the fixing ring 41.

[0041] Specifically, when it is necessary to clean the sediment in the storage cylinder 3, the fixing ring 41 can be manually rotated. The fixing ring 41 drives the lower end cover 4 to descend along the outer wall of the feed pipe 1, at which point the sediment in the storage cylinder 3 falls out. After cleaning, the fixing ring 41 is rotated in the opposite direction to reset the lower end cover 4, thereby closing the annular opening at the lower end of the storage cylinder 3. Alternatively, the operator can insert a long rod into the ear ring seat 42 to drive the fixing ring 41 to rotate.

[0042] Furthermore, the fixed ring seat 61 includes an inner ring 611, a lower ring plate 612, an upper ring plate 613, and an outer ring 614. The inner ring 611 is fixedly sleeved on the lower outer side of the feeding pipe 1. The inner sides of the upper ring plate 613 and the lower ring plate 612 are respectively fixed to the upper and lower ends of the inner ring 611. The outer sides of the upper ring plate 613 and the lower ring plate 612 are respectively fixed to the upper and lower ends of the outer ring 614.

[0043] Specifically, the inner ring 611, the lower ring plate 612, the upper ring plate 613, and the outer ring 614 together form an annular space for installing the drive assembly 64.

[0044] Furthermore, the lower end of the left arc-shaped scraper 62 is fixed with a number of left scraping teeth 621, and the lower end of the right arc-shaped scraper 63 is fixed with a number of right scraping teeth 631.

[0045] Specifically, by setting the left scraper tooth 621 and the right scraper tooth 631, they can effectively cut into the sediment layer, thereby improving the scraping efficiency of the left arc-shaped scraper 62 and the right arc-shaped scraper 63.

[0046] Furthermore, the left side surface of the lower ring plate 612 is provided with a through groove 6121 on both the front and back sides, and the right side surface of the lower ring plate 612 is provided with a through groove 6123 on both the front and back sides. The upper end of the left arc-shaped scraper 62 is fixedly connected with a connecting block 622 on both the front and back sides. The two sets of connecting blocks 622 are respectively slidably disposed inside the two sets of through grooves 6121. The upper ends of the two sets of connecting blocks 622 are jointly fixedly provided with a left arc-shaped rod 623. The upper end of the right arc-shaped scraper 63 is fixedly connected with a connecting rod 632 on both the front and back sides. The two sets of connecting rods 632 are respectively slidably disposed inside the two sets of through grooves 6123. The upper ends of the two sets of connecting rods 632 are jointly fixedly provided with a right arc-shaped rod 633.

[0047] Specifically, when the drive assembly 64 drives the left arc-shaped scraper 62 to move, the left arc-shaped scraper 62 causes the two sets of connecting blocks 622 to slide within the two sets of through slots 6121, and also indirectly causes the left arc-shaped rod 623 to move synchronously. When the drive assembly 64 drives the right arc-shaped scraper 63 to move, the right arc-shaped scraper 63 causes the two sets of connecting rods 632 to slide within the two sets of through slots 6123, and also indirectly causes the right arc-shaped rod 633 to move synchronously. Through slots 6121 and 6123 respectively guide and limit the left arc-shaped scraper 62 and the right arc-shaped scraper 63, ensuring that they do not deviate from their designated positions.

[0048] Furthermore, the drive assembly 64 includes two sets of short shafts 640, two sets of gears 641, two sets of left racks 642, and two sets of right racks 643. The two sets of short shafts 640 are rotatably connected to the middle of the front and rear sides of the inner ring 611, respectively. The two sets of gears 641 are fixedly sleeved on the outside of the two sets of short shafts 640, respectively. The two sets of left racks 642 are fixedly connected to the front and rear ends of the right side of the left arc-shaped rod 623, respectively, and the two sets of left racks 642 are respectively meshed with the lower ends of the two sets of gears 641. The two sets of right racks 643 are fixedly connected to the front and rear ends of the right side of the right arc-shaped rod 633, respectively, and the two sets of right racks 643 are respectively meshed with the upper ends of the two sets of gears 641. A synchronizing element 644 is connected to one side of the inner ring 611 to drive the two sets of gears 641 to rotate synchronously in the same direction.

[0049] Specifically, by driving the two sets of gears 641 to rotate counterclockwise synchronously via the synchronizing element 644, the two sets of right racks 643 move synchronously to the left, and the two sets of left racks 642 move synchronously to the right. The two sets of right racks 643 indirectly drive the right arc-shaped scraper 63 to move to the left via the right arc-shaped rod 633, and the two sets of left racks 642 indirectly drive the left arc-shaped scraper 62 to move to the right via the left arc-shaped rod 623, thus bringing the left arc-shaped scraper 62 and the right arc-shaped scraper 63 closer together. When it is necessary to move the left arc-shaped scraper 62 and the right arc-shaped scraper 63 further apart, simply drive the two sets of gears 641 to rotate clockwise synchronously via the synchronizing element 644.

[0050] Furthermore, the lower ring plate 612 has lower slide rails 6125 fixedly connected to the front and rear sides of the upper surface of the lower ring plate 612, and a left slide bar 6421 fixedly connected to the lower surface of the left rack 642. The two sets of left slide bars 6421 are respectively slidably disposed inside the two sets of lower slide rails 6125. The upper ring plate 613 has upper slide rails 6131 fixedly connected to the front and rear sides of the lower surface of the upper ring plate 613, and a right slide bar 6431 fixedly connected to the upper surface of the right rack 643. The two sets of right slide bars 6431 are respectively slidably disposed inside the two sets of upper slide rails 6131.

[0051] Specifically, when the left rack 642 slides, it causes the left slider 6421 to move along the lower slide rail 6125. When the right rack 643 slides, it causes the right slider 6431 to move along the upper slide rail 6131. ​​The lower slide rail 6125 and the upper slide rail 6131 serve to guide and limit the left slider 6421 and the right slider 6431, respectively.

[0052] Furthermore, the lower right surface of the lower ring plate 612 is provided with two sets of guide grooves 6122 that communicate with the through groove 6121, and the lower left surface of the lower ring plate 612 is provided with two sets of guide grooves 6124 that communicate with the through groove 6123. The lower right end of each of the two sets of connecting blocks 622 is fixedly connected with a left sealing plate 624, and the two sets of left sealing plates 624 are slidably connected inside the two sets of guide grooves 6122. The lower left end of each of the two sets of connecting rods 632 is fixedly connected with a right sealing plate 634, and the two sets of right sealing plates 634 are slidably connected inside the two sets of guide grooves 6124.

[0053] Specifically, the left sealing plate 624 and the right sealing plate 634 respectively seal the first through groove 6121 and the second through groove 6123, preventing sediment between the left arc-shaped scraper 62 and the right arc-shaped scraper 63 from entering the fixed ring seat 61 through through groove 6121 and through groove 6123. When the connecting block 622 slides in through groove 6121, it will cause the left sealing plate 624 to slide in guide groove 6122. When the connecting rod 632 slides in through groove 6123, it will cause the right sealing plate 634 to slide in guide groove 6124.

[0054] Furthermore, the synchronizing component 644 includes a second motor 6441, a second gear 6442, and a long shaft 6444. The second motor 6441 is fixedly installed on the left side wall of the inner ring 611. The second gear 6442 is fixedly sleeved on the outside of the output shaft of the second motor 6441. The long shaft 6444 is rotatably connected to the left side of the inner ring 611 through two sets of support seats 6443. The front and rear ends of the long shaft 6444 are both fixedly sleeved with a first sprocket 6445. The outside of the short shaft 640 and on one side of the first gear 641, a second sprocket 6446 is fixedly sleeved. The outside of the first sprocket 6445 and the second sprocket 6446 are together sleeved with a synchronizing chain 6447. The middle position of the outside of the long shaft 6444 is fixedly sleeved with a third gear 6448, which meshes with the second gear 6442.

[0055] Specifically, when it is necessary to drive the two sets of gears 641 to rotate counterclockwise synchronously, it is only necessary to drive the output shaft of the second motor 6441 to rotate clockwise. At this time, the second gear 6442 rotates clockwise, thereby driving the third gear 6448 meshing with it to rotate counterclockwise. The third gear 6448 then drives the long shaft 6444 and the sprockets 6445 at both ends to rotate counterclockwise. Under the action of the synchronizing chain 6447, the two sets of sprockets 6446 also rotate counterclockwise synchronously. The sprockets 6446 then drive the first gear 641 to rotate counterclockwise through the short shaft 640. Conversely, driving the output shaft of the second motor 6441 to rotate counterclockwise is sufficient, thus achieving the synchronous counterclockwise rotation of the two sets of gears 641.

[0056] Furthermore, the support member 7 includes a column 71, a horizontal support plate 72, and a threaded adjusting column 73. The column 71 is fixedly connected to the upper edge of the top surface of the top plate 2. One end of the horizontal support plate 72 is fixedly connected to the upper end of the column 71. The threaded adjusting column 73 is threadedly connected to the other end of the horizontal support plate 72. A base plate 74 is fixedly connected to the lower end of the threaded adjusting column 73, and a handwheel 75 is fixedly connected to the upper end of the threaded adjusting column 73.

[0057] Specifically, by rotating the handwheel 75, the handwheel 75 drives the threaded adjusting column 73 to rotate, thereby changing the length of the threaded adjusting column 73 extending out of the horizontal support plate 72, and thus changing the support height of the support member 7.

[0058] It should be noted that both Motor 1 (52) and Motor 2 (6441) mentioned above are electrically connected to the control terminal. The control terminal transmits signals and supplies power to Motor 1 (52) and Motor 2 (6441) via cables, and the cable layout can be flexibly arranged according to the actual usage environment, space layout, and equipment requirements.

[0059] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
