[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The sampling structure for quality testing of building pile foundations, after the pile foundation sampling is completed, sends a signal through the controller, causing the power output shaft of motor one to rotate. Motor one drives the rotating rod to rotate, which in turn drives the gear to rotate. Through the meshing of the gear and rack, and through the opening of the rotating groove, the gear drives the rack to move on the inner wall of the moving groove. When the rack moves, it also drives the limiting rod to move on the inner wall of the limiting groove. The limiting rod limits the rack and prevents it from deviating during movement. At the same time, the movement of the rack also drives the protective shell to move, covering the top of the placement shell, thereby protecting the sampling structure on the inner wall of the placement shell.

[0013] 2. The sampling structure for quality testing of the building's pile foundation, when sampling the pile foundation, sends a signal through the controller, causing the power output shaft of motor two to rotate upon receiving the signal. Motor two drives the rotating shaft to rotate, which in turn drives rotating block one to rotate. Rotating block one then applies rotational force to tension belt one, which transmits this force to the inner wall of rotating block two, causing it to rotate. This rotation also drives rotating column to rotate on the inner wall of the fixed plate. Rotating column then drives rotating block three to rotate, which in turn drives tension belt two to rotate. Tension belt two then drives rotating block four and the cylinder to rotate on the inner wall of the limiting plate. The rotation of tension belt two then moves the force-bearing rod, which in turn moves the sampling cylinder, thus achieving better movement of the sampling cylinder. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] See also Figure 1 - Figure 6 A sampling structure for quality testing of building pile foundations includes a placement shell 1. A controller 2 and a placement block 3 are fixedly mounted on the outer wall of the placement shell 1. A fixing block 12 is fixedly mounted on the top of the placement shell 1. A placement plate 17 is fixedly mounted on the inner wall of the placement shell 1. A fixing plate 18 and a limiting plate 25 are fixedly mounted on the outer wall of the placement plate 17. A sliding groove 22 is provided on the top of the placement plate 17. A second motor 13 is fixedly mounted on the outer wall of the fixing block 12. A rotating shaft 14 is fixedly mounted on the power output shaft of the second motor 13. A first rotating block 15 is fixedly mounted on the outer wall of the rotating shaft 14. A tension belt 16 is rotatably connected to the inner wall of the first rotating block 15. A rotating column 19 is rotatably connected to the inner wall of the fixing plate 18. Rotating block 20 and rotating block 3 23 are fixedly mounted on the outer wall of 9. The inner wall of rotating block 3 23 is rotatably connected to tension belt 24. The inner wall of limiting plate 25 is rotatably connected to cylinder 26. Rotating block 4 27 is fixedly mounted on the outer wall of cylinder 26. Sliding block 29 is slidably connected to the inner wall of sliding groove 22. Force rod 28 is fixedly mounted on the top of sliding block 29. Base plate 30 is fixedly mounted on the bottom of sliding block 29. Support rod 31 and electric telescopic rod 32 are fixedly mounted on the bottom of base plate 30. Sliding plate 33 is fixedly mounted on the telescopic end of electric telescopic rod 32. Rotary motor 34 is fixedly mounted on the top of sliding plate 33. Sampling cylinder 35 is fixedly mounted on the power output shaft of rotary motor 34.

[0023] In the above structure, during the pile foundation sampling process, the controller 2 sends a command signal. After receiving the signal, the power output shaft of motor 2 13 starts to rotate. This rotation drives the rotating shaft 14 to rotate synchronously. When the rotating shaft 14 rotates, it further drives the rotation of rotating block 15. During the rotation of rotating block 15, it applies rotational force to tension belt 16. Tension belt 16 then transmits this rotational force to the inner wall of rotating block 20, causing rotating block 20 to rotate. This, in turn, drives rotating column 19 to rotate on the inner wall of fixed plate 18. As rotating column 19 rotates, rotating block 3 23 is driven to rotate, which in turn drives tension belt 24. The rotation of the tension belt 24 not only drives the rotating block 27 and the cylinder 26 to rotate on the inner wall of the limiting plate 25, but also drives the force rod 28 to move. The movement of the force rod 28 further promotes the movement of the sampling cylinder 35, thereby optimizing the movement effect of the sampling cylinder 35. When the sampling cylinder 35 moves to the predetermined position, the electric telescopic rod 32 and the rotary motor 34 also receive the signal sent by the controller 2. At this time, the telescopic rod of the electric telescopic rod 32 drives the sliding plate 33 to move along the outer wall of the support rod 31. At the same time, the power output shaft of the rotary motor 34 drives the sampling cylinder 35 to rotate during the movement of the sliding plate 33, thereby completing the sampling operation of the pile foundation.

[0024] In a preferred embodiment: the top of the placement shell 1 is provided with a moving groove 7 and a limiting groove 8 respectively. The inner wall of the limiting groove 8 is slidably connected to a limiting rod 10. The outer wall of the limiting rod 10 is fixedly fitted with a rack 9. The outer wall of the placement shell 1 is provided with a rotating groove 21. The outer wall of the placement block 3 is fixedly fitted with a motor 4. The power output shaft of the motor 4 is fixedly fitted with a rotating rod 5. The outer wall of the rotating rod 5 is fixedly fitted with a gear 6. The top of the rack 9 is fixedly fitted with a protective shell 11.

[0025] In the above structure, after the pile foundation sampling process is completed, the controller 2 issues a command to cause the receiving motor 4 to start rotating its power output shaft after receiving the signal. This rotation is transmitted to the rotating rod 5, causing the rotating rod 5 to rotate synchronously. During the rotation of the rotating rod 5, it further drives the gear 6 to rotate. The gear 6 and the rack 9 are connected by a meshing transmission mechanism. Therefore, the rotation of the gear 6 will drive the rack 9 to move on the inner wall of the moving groove 7. At the same time, when the rack 9 moves, it will drive the limiting rod 10 to move on the inner wall of the limiting groove 8. The function of the limiting rod 10 is to limit the rack 9 and ensure that it will not deviate during the movement. In addition, the movement of the rack 9 will also drive the protective shell 11 to move synchronously, thereby covering the top of the placement shell 1 and protecting the sampling structure on the inner wall of the placement shell 1 from damage.

[0026] In a preferred embodiment, the gear 6 meshes with the rack 9 for transmission, and the rack 9 is slidably connected to the inner wall of the movable groove 7.

[0027] In the above structure, when the gear 6 rotates, it will drive the rack 9 to move on the inner wall of the moving groove 7, and the moving groove 7 will limit the rack 9.

[0028] In a preferred embodiment: the sliding plate 33 is slidably connected to the outer wall of the support rod 31, and the force-bearing rod 28 is fixedly assembled with the tension band 24.

[0029] In the above structure, the sliding plate 33 is limited by the support rod 31, and the tension belt 24 will drive the force rod 28 and the sliding block 29 to move on the inner wall of the sliding groove 22 when it rotates.

[0030] In a preferred embodiment: tension band 16 is rotatably connected to the inner walls of rotating block 15 and rotating block 20 respectively, and tension band 24 is rotatably connected to the inner walls of rotating block 3 and rotating block 4 respectively.

[0031] In the above structure, rotating block 15 can drive rotating block 20 to rotate via tension belt 16 when rotating, and rotating block 3 23 can drive rotating block 4 27 to rotate via tension belt 24 when rotating.

[0032] In a preferred embodiment, there are two of each of the following: rotating block 3 23, tension band 24, and rotating block 4 27, and the two rotating blocks 3 23, tension band 24, and rotating block 4 27 are located on the outer walls of rotating column 19 and cylinder 26, respectively.

[0033] In the above structure, the two rotating blocks 23, the tension belt 24, and the rotating block 27 are used to make the force-bearing rod 28 more stable when it is moved, and the force-bearing rod 28 will not tilt.

[0034] Working principle: During pile foundation sampling, the controller 2 sends a signal to trigger the power output shaft of motor 2 13 to rotate. Motor 2 13 then drives the rotating shaft 14 to rotate. During the rotation of the rotating shaft 14, the rotating block 15 rotates and applies rotational force to the tension belt 16. The tension belt 16 transmits the rotational force to the inner wall of the rotating block 20, causing it to rotate. This rotation drives the rotating column 19 to rotate on the inner wall of the fixed plate 18. The rotating column 19, in turn, drives the rotating block 3 23, which in turn causes the tension belt 24 to rotate. The tension belt 24 drives the rotating block 4 27 and the cylinder 26 to rotate on the inner wall of the limiting plate 25. At the same time, the rotation of the tension belt 24 causes the force rod 28 to move, which in turn pushes the sampling cylinder 35 to move, thus optimizing its movement effect. When the sampling cylinder 35 reaches the appropriate position, the electric telescopic rod 32 and the rotating motor 34 also receive the signal from the controller 2. The telescopic rod of the electric telescopic rod 32 pushes the sliding plate 33 to move on the outer wall of the support rod 31. During the movement of the sliding plate 33, the power output shaft of the rotary motor 34 drives the sampling cylinder 35 to rotate to complete the pile foundation sampling. After the sampling is completed, the controller 2 sends a signal again. The power output shaft of the motor 4 receives the signal and rotates. The rotation of the motor 4 drives the rotating rod 5 to rotate. When the rotating rod 5 rotates, it causes the gear 6 to rotate. The gear 6 meshes with the rack 9 and passes through the opening of the rotating groove 21, so that the gear 6 pushes the rack 9 to move on the inner wall of the moving groove 7 when it rotates. During the movement, the rack 9 drives the limiting rod 10 to move on the inner wall of the limiting groove 8 to limit the rack 9 and prevent it from deviating during movement. At the same time, the movement of the rack 9 also drives the protective shell 11 to move to cover the top of the placement shell 1, thereby protecting the sampling structure on the inner wall of the placement shell 1.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
