[0004] Through long-term observation, although the existing positioning frame can guide the pile casing, its diameter port is usually fixedly set and difficult to adjust, making it troublesome to install pile casings of different sizes. Therefore, an anti-tilting and deviation-correcting device for pile casing installation is proposed for the above problems. Summary of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Next, specific embodiments are given.

[0025] As Figures 1-4As shown in the figure, an anti-tilting and deviation-correcting device for pile casing installation includes a support frame 1; multiple connecting plates 11 are fixedly connected to the middle of the support frame 1; a telescopic rod 12 is fixedly connected to the side wall of the connecting plate 11; the output end of the telescopic rod 12 is fixedly connected to a first support plate 13; a first toothed rail 14 is fixedly connected to the middle of the output end of the telescopic rod 12; a connecting member 15 is fixedly connected to the top of the telescopic rod 12; a toothed block 16 is rotatably connected to the middle of the connecting member 15, and the toothed block 16 is meshed with the inner wall of the first toothed rail 14; a sliding plate 17 is slidably connected to the middle of the support frame 1; multiple second toothed rails 18 are fixedly connected to the top of the sliding plate 17, and the second toothed rails 18 are meshed with the toothed block 16; the second toothed rails 18 and the first toothed rails 14 are arranged in a staggered manner; a servo motor 19 is installed at the bottom of the connecting plate 11; the output end of the servo motor 19 is fixedly connected to a screw rod 110, and the middle of the screw rod 110 is threadedly connected to the sliding plate 17; during operation, the staff needs to fix the support frame 1 in a specified area and align its middle with the hole of the pile casing to be installed. Subsequently, after the staff lifts the pile casing with a lifting tool, it moves downward along the inner walls of multiple first support plates 13 and conducts guiding work. By arranging a servo motor 19 in the middle of a group of connecting plates 11, the staff can then start the switch of the servo motor 19, so that the output end of the servo motor 19 drives the screw rod 110 to rotate, and the entire sliding plate 17 slides up and down on the inner wall of the support frame 1. When the entire sliding plate 17 slides downward, multiple second toothed rails 18 will pull the toothed block 16 to rotate in the middle of the connecting member 15, and during the rotation of the toothed block 16, multiple first toothed rails 14 and the first support plates 13 can be synchronously pulled to expand outward, thereby adjusting the aperture formed by multiple first support plates 13. This step can improve the flexibility during the guiding of the pile casing by arranging multiple slidable first support plates 13 in the middle of the support frame 1, reduce the problem of mismatch between the guiding aperture and the pile casing, which may cause tilting or shaking during the installation process. At the same time, the arranged sliding plate 17 can synchronously adjust multiple first support plates 13, reduce the distance deviation between multiple first support plates 13, and prevent the pile casing from getting stuck when sliding.

[0026] As Figure 1 , 2As shown in FIGS. 3 and 4, multiple sets of connecting cylinders 2 are fixedly connected to the middle of the support frame 1; a first pin 21 is slidably connected to the inner wall of the connecting cylinder 2; multiple sets of spring rods 22 are fixedly connected to the inner wall of the support frame 1; a second support plate 23 is fixedly connected to the output end of the spring rod 22 and the tops of two sets of connecting cylinders 2; a second pin 24 is slidably connected to the middle of the output end of the spring rod 22; multiple sets of clamping members 25 matching the shape of the second pin 24 are fixedly connected to the inner wall of the support frame 1; during operation, by arranging multiple sets of slidable connecting cylinders 2 in the middle of the support frame 1, when it is necessary to fix the placement position of the support frame 1, the staff can press down the top of the second support plate 23, so that the end of the first pin 21 sinks into the ground, and the first pin 21 will compress the output end of the spring rod 22 to retract during the movement. Until the end of the second pin 24 is aligned with the clamping member 25, the staff can push the end of the second pin 24 and make it slide at the output end position of the spring rod 22, and then it can be stuck inside the inner wall of the clamping member 25, thus completing the fixing work of the second pin 24. This step cooperates with the arranged first pin 21 and the sharp end at its bottom, so as to improve the overall stability of the support frame 1 during placement and fixing. The arranged spring rod 22 can, when it is necessary to take out the end of the first pin 21 from the ground, cooperate with its reaction force to pop out the end of the first pin 21, reducing the trouble problem that occurs to the staff during the taking-out process.

[0027] As Figure 3 shown, a first fixing plate 3 is fixedly connected to the bearing end of the tooth block 16; a frame 31 is fixedly connected to the middle of the first fixing plate 3; a cleaning net 32 is fixedly connected to the inner wall of the frame 31; during operation, by arranging a first fixing plate 3 at the output end position of the tooth block 16, when the tooth block 16 rotates, the frame 31 can be driven to rotate synchronously, and the cleaning net 32 can clean and adsorb and collect surrounding dust and other impurities. This step cooperates with the arranged cleaning net 32 to improve the cleanliness of the working environment of the tooth block 16, reducing the problem that a large amount of impurities accumulate and adhere to the middle of the tooth block 16, resulting in greater wear between it and the second tooth rail 18 or the first tooth rail 14 during subsequent rotation.

[0028] As Figure 4 shown, an inner groove 4 is formed at the end of the clamping member 25, and the inner groove 4 is arranged in a horn shape; a smooth member 41 is fixedly connected to the end of the second pin 24; during operation, by arranging a smooth member 41 at the end of the second pin 24, when the second pin 24 is guided in position, the smooth member 41 will move along the inner wall of the inner groove 4 and pour the second pin 24 into the inner wall of the clamping member 25. This step, under the action of the inclined smooth member 41, can guide the position of the second pin 24, reducing the problem that the angle of the second pin 24 is deviated, resulting in trouble when the spring rod 22 is fixed.

[0029] AsFigure 2 As shown, a second fixing plate 5 is fixedly connected to the bottom of the first support plate 13; a limiting groove 51 is formed in the inner wall of the second fixing plate 5; during operation, by providing the limiting groove 51 at the bottom of the first support plate 13, when the pile casing slides downward, the edge thereof will slide along the inner wall of the limiting groove 51 until the pile casing is stuck inside the designated hole. This step, in cooperation with the multiple sets of limiting grooves 51 provided, can further improve the stability of the pile casing during sliding and reduce the problem that the contact area between the multiple sets of first support plates 13 and the surface of the pile casing is small, resulting in shaking and trouble.

[0030] As Figure 4 As shown, multiple sets of friction members 6 are fixedly connected to the top of the second support plate 23; during operation, by providing the multiple sets of friction members 6 at the top of the second support plate 23, when the operator presses the top of the second support plate 23, it will first come into contact with the multiple sets of friction members 6. This step, under the action of the multiple sets of friction members 6, can increase the friction force of the second support plate 23 during fixation and reduce the problem of slipping off.

[0031] As Figure 2 As shown, a limiting block 7 is fixedly connected to the bottom of the screw 110; during operation, by providing the limiting block 7 at the bottom of the screw 110, during the sliding process of the slide plate 17, it will gradually approach the position of the limiting block 7 and be position-limited by the limiting block 7. This step, in cooperation with the provided limiting block 7, can improve the stability of the slide plate 17 during sliding and reduce the phenomenon of its separation from the screw 110.

[0032] Working principle: Fix the support frame 1 in a specified area and align its middle part with the hole of the pile casing to be installed. Then, the staff uses a lifting tool to lift the pile casing, and it moves downward along the inner walls of multiple first support plates 13 for guiding. A servo motor 19 is provided in the middle of a set of connecting plates 11. Then, the switch of the servo motor 19 can be started, so that the output end of the servo motor 19 drives the screw rod 110 to rotate, and the whole slide plate 17 slides up and down on the inner wall of the support frame 1. When the whole slide plate 17 slides downward, multiple groups of second toothed rails 18 will pull the toothed block 16 to rotate in the middle of the connecting piece 15. When the toothed block 16 rotates, it can synchronously pull multiple groups of first toothed rails 14 and the first support plates 13 to expand outward, so as to adjust the aperture formed by multiple groups of first support plates 13. Multiple sets of slidable connecting cylinders 2 are provided in the middle of the support frame 1. When it is necessary to fix the placement position of the support frame 1, the staff can press the top of the second support plate 23 downward, so that the end of the first pin 21 sinks into the ground. During the movement of the first pin 21, it will compress the output end of the spring rod 22 to retract. Until the end of the second pin 24 is aligned with the clamping part 25, the staff can push the end of the second pin 24 and make it slide at the output end position of the spring rod 22, and then it can be stuck on the inner wall of the clamping part 25, thus completing the fixing work of the second pin 24. A first fixing plate 3 is provided at the output end position of the toothed block 16. When the toothed block 16 rotates, it can synchronously drive the frame 31 to rotate, and the cleaning net 32 can clean and adsorb and collect dust and other impurities around. A smoothing part 41 is provided at the end of the second pin 24. When the second pin 24 is guiding its position, the smoothing part 41 will move along the inner groove 4 inner wall and pour the second pin 24 into the inner wall of the clamping part 25. A limiting groove 51 is provided at the bottom of the first support plate 13. When the pile casing slides downward, its edge will slide along the inner wall of the limiting groove 51 until the pile casing is stuck in the specified hole. Multiple friction parts 6 are provided at the top of the second support plate 23. When the staff presses the top of the second support plate 23, it will first contact with multiple friction parts 6. A limiting block 7 is provided at the bottom of the screw rod 110. When the slide plate 17 slides, it will gradually approach the position of the limiting block 7 and be limited in position by the limiting block 7.
