Description

Technical Field

[0001] The present invention relates to the technical field of pile foundation detection, and specifically to a pile foundation detection device for building engineering. Background Art

[0002] Existing pile foundation detection devices can only detect the depth and inner diameter of pile foundations, and do not include a stability detection mechanism. Therefore, the detection method is relatively single, which affects the practicability and detection diversity of the pile foundation detection device. The pile foundation detection device with the application number CN202321900420.6 includes a pile foundation body and a detection frame, which solves the problem that the existing pile foundation detection device can only detect the depth and inner diameter of pile foundations and does not include a stability detection mechanism. Therefore, the detection method is relatively single, which affects the practicability and detection diversity of the pile foundation detection device.

[0003] Although the device has the above advantages, there are still the following defects in actual use:

[0004] 1) The device drives the knocking block to swing through a connecting column to knock and detect the pile foundation. On the one hand, the swinging amplitude is fixed, resulting in a relatively single detection force. On the other hand, the knocking block moves by compressing a spring, which easily reduces the knocking force, thereby deteriorating the detection effect.

[0005] 2) The device uses a jack for pile foundation compressive testing, but the connection between the detection frame and the pile foundation is relatively loose, resulting in poor load-bearing capacity of the support and a poor detection effect.

Moreover, by utilizing the telescoping of the reset rod and the movement of the shaft sleeve, the rotation of the rotating rod can be facilitated, and the position of the knocking part can be fixed through the connection between the key shaft and the shaft sleeve, so as to improve the stability of the knocking part during detection.

[0024] (3) By arranging a traction component, the linear motor drives the sliding plate to move, and the flexible plate can be pulled to deform through the traction rope.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figure 1-6 , the present invention provides a technical solution: a pile foundation detection device for building engineering:

[0035] Embodiment 1: Refer to the attached drawings of the specificationFigure 1 , attached Figure 2 , attached Figure 4 ;

[0036] It includes a bracket 1, and a knocking mechanism is arranged outside the bracket 1. The knocking mechanism includes a fixing strip 2, the outer surface of the fixing strip 2 is fixedly connected with the outer surface of the bracket 1, a resilient plate 3 is arranged outside the fixing strip 2, the resilient plate 3 is arranged perpendicular to the fixing strip 2, and the resilient plate 3 can be made of a material with high hardness and good elasticity. For example, it can be made of the leaf spring material of an automotive leaf spring. Both ends of the resilient plate 3 are sleeved with connecting sleeves 4. The connection between the connecting sleeve 4 and the resilient plate 3 facilitates the replacement of the resilient plate 3 after fatigue, and different resilient plate 3 with different elastic coefficients can also be replaced during detection. A knocking member 5 is arranged outside one side connecting sleeve 4, a pile foundation is arranged outside the knocking member 5, and the knocking members 5 are respectively a sphere, a prism and a rectangular bar to provide point, line and surface knocking effects. The outer surface of the other side connecting sleeve 4 is fixedly connected with the outer surface of the fixing strip 2. Bolts 9 penetrate and are slidably connected through the bodies of the two connecting sleeves 4, and one end of the bolt 9 penetrates and is threadedly connected with the body of the resilient plate 3. A traction rope 7 is arranged outside one side connecting sleeve 4, and a clamp 10 is movably connected outside the knocking member 5. During compressive testing, the clamp 10 is fixed on the surface of the pile foundation and is clamped with the rectangular bar-shaped knocking member 5 to improve the bearing capacity of the bracket 1. The clamp 10 is sleeved outside the pile foundation. The other end of the traction rope 7 is wound and connected with a hook 11, and the outer surface of the hook 11 is fixedly connected with the outer surface of one side connecting sleeve 4. A fixed pulley 12 is movably connected to the outer surface of the traction rope 7, and the outer surface of the fixed pulley 12 is fixedly connected with the outer surface of the fixing strip 2. An arc plate 13 is movably connected to the outer surface of the traction rope 7. The arc plate 13 can play a side protection role and can prevent the traction rope 7 from disconnecting from the fixed pulley 12. The outer surface of the arc plate 13 is fixedly connected with the outer surface of the fixed pulley 12.

[0037] In this embodiment, after the traction rope 7 is redirected by the fixed pulley 12, it pulls on the lower part of the resilient plate 3. The movement of the knocking member 5 is driven by the deformation of the resilient plate 3, and the knocking force is adjusted through the deformation amount of the resilient plate 3. Different knocking methods are provided through the knocking members 5 with various shapes. By releasing the traction rope 7, the resilient plate 3 rebounds to drive the knocking member 5 to reset, so that the knocking member 5 knocks on the pile foundation for detection. At the same time, during compressive testing, the clamp 10 is fixed on the surface of the pile foundation, and through the clamping of the rectangular bar-shaped knocking member 5 and the clamp 10, the pile foundation and the bracket 1 clamp the jack, thereby improving the stability of the jack and the bracket 1, and then the pile foundation can be subjected to compressive testing through the jack.

[0038] Embodiment 2: On the basis of Embodiment 1, referring to the attached drawings in the specification Figure 2 , attached Figure 3 ;

[0039] An alternating component 6 is provided outside the striking member 5. The alternating component 6 includes two support plates 61. The outer surfaces of the two support plates 61 are fixedly connected to the outer surface of the side connecting sleeve 4 on one side. A rotating rod 62 is rotatably connected through the body of the support plate 61. The rotation of the rotating rod 62 can alternate the positions of the striking member 5 in multiple ways to achieve striking detection in multiple ways. A connecting rod 63 is fixedly connected to the outer surface of the rotating rod 62. One end of the connecting rod 63 is fixedly connected to the outer surface of the striking member 5. One end of the rotating rod 62 is fixedly connected to a key shaft 64. The outer diameter of the key shaft 64 is larger than that of the rotating rod 62, which can axially limit the rotating rod 62 and improve the stability of the relative position of the striking member 5. A sleeve 65 is movably connected to the outer surface of the key shaft 64. The cooperation between the sleeve 65 and the key shaft 64 can radially limit the rotating rod 62 to improve the radial stability of the striking member 5. A reset rod 66 is fixedly connected to the outer surface of the sleeve 65. The reset rod 66 is made of a spring rod, which can facilitate the stability of the sleeve 65. One end of the reset rod 66 is fixedly connected to the outer surface of the support plate 61.

[0040] In this embodiment, when it is necessary to replace the striking member 5 with different shapes for detection, axially pull the sleeve 65 to make it slide and disengage from the limit of the key shaft 64, and at the same time stretch the output end of the reset rod 66. Then rotate the rotating rod 62 through the connecting rod 63 to alternate the position of the striking member 5. After the position adjustment is completed, release the sleeve 65. Through the retraction of the output end of the reset rod 66, the sleeve 65 is reset and connected to the key shaft 64, so as to fix the position of the striking member 5. Then the pile foundation can be detected by the striking member 5 after alternation.

[0041] Embodiment 3: On the basis of Embodiment 2, refer to the appended Figure 4 and appended Figure 5 ;

[0042] An external traction assembly 8 is provided for the traction rope 7. The traction assembly 8 includes a chute 81. The chute 81 is opened on the body of the fixing strip 2 and is in a through state. A slide plate 82 is slidably connected inside the chute 81. The cross-section of the slide plate 82 is in an I-shape to enhance its own stability. One end of the outer surface of the slide plate 82 is fixedly connected to the traction rope 7. A groove 83 is opened inside the chute 81. A linear motor 84 is arranged inside the groove 83. The linear motor 84 adopts a shaft-type linear motor 84 to provide a greater traction force. The linear motor 84 slides inside the groove 83 to drive the slide plate 82 to move accordingly. A fixing plate 85 is fixedly connected to the outer surface of the linear motor 84. Two clamping jaws 86 are rotatably connected to the outer surface of the fixing plate 85. Both ends of the clamping jaws 86 are chamfered. One end of the clamping jaws 86 is movably connected to a clamping rod 88. The cross-section of the clamping rod 88 is in a T-shape and the end is chamfered to cooperate with the chamfer of the clamping jaws 86 so that the clamping jaws 86 clamp the clamping rod 88. The outer surface of the clamping rod 88 is fixedly connected to the outer surface of the slide plate 82. A buffer rod 89 is rotatably connected to the outer surface of the fixing plate 85. The buffer rod 89 is made of a spring rod. Both ends can be respectively connected to the clamping jaws 86 and the fixing plate 85 through rotating connectors (not shown in the figure) to maintain the relative stability of the end of the clamping jaws 86. One end of the buffer rod 89 is rotatably connected to the outer surface of the clamping jaws 86.

[0043] In this embodiment, the linear motor 84 moves inside the groove 83, driving the fixing plate 85 to approach the slide plate 82. During the movement, the chamfer at one end of the clamping jaws 86 interacts with the chamfer at the end of the clamping rod 88, thus causing the clamping jaws 86 to rotate and the distance between the ends of the two clamping jaws 86 to be greater than the width of the clamping rod 88, and enabling one end of the clamping rod 88 to be located between the two clamping jaws 86. When the clamping jaws 86 rotate, the buffer rod 89 is stretched. After the contact is released, the output end of the buffer rod 89 rebounds to drive the clamping jaws 86 to reset. Then the linear motor 84 moves in the reverse direction. By clamping the clamping rod 88 with one end of the two clamping jaws 86, the slide plate 82 is pulled to move synchronously inside the chute 81, thereby pulling one side of the flexible plate 3 through the slide plate 82 and the traction rope 7, and controlling the deformation amount of the flexible plate 3 by the movement distance of the linear motor 84.

[0044] Embodiment 4: On the basis of Embodiment 3, refer to the appended drawings of the specification Figure 4 and Figure 6 ;

[0045] An unlocking unit 87 is disposed outside the jaw 86. The unlocking unit 87 includes a connecting groove 871 which is formed in the body of the slide plate 82 and is in a through state. A slider 872 is movably connected inside the connecting groove 871. One side of the slider 872 abuts against the inner wall of the sliding groove 81. The outer surface of the slider 872 is slidably connected to the inside of the sliding groove 81. A resisting rod 873 is fixedly connected to the outer surface of the slider 872. There are two resisting rods 873, and the distance between them is less than the distance between the other ends of the two jaws 86. By contacting the chamfers at the other ends of the jaws 86, the other ends of the two jaws 86 are squeezed and made to approach each other. The outer surface of the resisting rod 873 abuts against the outer surface of the jaw 86. A light-sensitive plate 874 is fixedly connected to the outer surface of the slider 872. The light-sensitive plate 874 is made of a light-sensitive material and can receive the rays of the spotlight 875. A spotlight 875 is disposed outside the light-sensitive plate 874. Both the spotlight 875 and the light-sensitive plate 874 are electrically connected to an external control circuit. Moreover, the slide plate 82 can wrap the spotlight 875, the light-sensitive plate 874, and the slider 872 through the connecting groove 871. The outer surface of the spotlight 875 is fixedly connected to the inside of the sliding groove 81. A lead screw 876 is threadedly connected through the body of the slider 872. The outer surface of the lead screw 876 is rotatably connected to the inside of the connecting groove 871. One end of the lead screw 876 is rotatably connected to the inside of the sliding groove 81 in an embedded manner. The other end of the lead screw 876 is fixedly connected to a driving motor 877 through a coupling. The driving motor 877 is made of a servo motor and is electrically connected to an external control circuit. The outer surface of the driving motor 877 is fixedly connected to the inside of the sliding groove 81 in an embedded manner.

[0046] In this embodiment, when it is necessary to control the deformation amount of the flexible plate 3, the corresponding movement amount of the slide plate 82 is calculated. Then, the spotlight 875 emits rays that strike the light-sensitive plate 874. The movement duration of the rays is obtained by the difference between the ray emission time and the reception time of the light-sensitive plate 874. Then, according to the speed of light, the distance between the two is calculated to determine the relative position of the slider 872. Then, according to the corresponding movement position of the slide plate 82, the driving motor 877 drives the slider 872 through the lead screw 876 to drive the resisting rod 873 to move to a suitable position. When the linear motor 84 drives the slide plate 82 and the jaw 86 to move, the other end of the jaw 86 contacts the resisting rod 873, so that the other ends of the two jaws 86 approach each other. Through the rotational action, the distance between the two ends of the two jaws 86 clamping the clamping rod 88 is increased, so as to release the clamping of the clamping rod 88, enabling the slide plate 82 to break away from the traction, and thus enabling the flexible plate 3 to rebound to achieve the automatic unlocking function.
