Description

Technical Field

[0001] This utility model relates to the field of pile foundation core sampling and monitoring technology, specifically to a pile foundation core sampling and monitoring device. Background Technology

[0002] Core drilling typically involves drilling along the pile top to the pile bottom using a geological drilling rig, reaching a certain depth in the bearing stratum. Core samples are then taken to examine the condition and strength of the pile, providing a direct and qualitative analysis of its quality. This allows for the acquisition of information on pile length, concrete strength, pile bottom sediment thickness, pile integrity, and the determination or identification of the soil and rock properties of the bearing stratum at the pile tip. Core drilling is commonly used for grouting reinforcement of broken piles and piles with inclusions.

[0003] The current publication number CN219196084U discloses a pile foundation core sampling and monitoring device, which relates to the field of pile foundation core sampling and testing technology. It improves the problem that when the ring track is placed on uneven ground, the upright needs to be frequently adjusted, which is quite troublesome. The device includes a base plate, a support ring rotatably mounted on the base plate, an upright fixedly mounted on the support ring, and two infrared rangefinders spaced apart on one side of the upright. Adjustment studs are threaded to the four corners of the base plate.

[0004] To address the issue of adjusting the horizontal position of the uprights, existing technology employs adjusting studs and a level. During use, the base plate can be leveled first, ensuring the uprights remain vertical. However, this leaves the rotating components exposed, increasing the risk of damage from loose mud and sand over time, thus raising operating costs. Utility Model Content

[0005] The purpose of this invention is to provide a core sampling and monitoring device for pile foundations to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A core sampling and monitoring device for pile foundations includes a support leg, a leveling unit on the top surface of the support leg, a rotating unit on one side of the leveling unit, a storage unit on one side of the rotating unit, and a lifting unit on one side of the storage unit.

[0008] The rotating unit includes a limiting plate, which is disposed on one side of the leveling unit. A limiting groove is formed inside the limiting plate, and a limiting block is formed in the rotating connecting hole inside the limiting groove. A gear one is fixedly connected to the surface of the limiting block, and a gear two is meshed with one side of the gear one. A motor one is fixedly sleeved on one side of the gear two, and one side of the motor one is bolted to the top surface of the limiting plate.

[0009] A further improvement of the present invention is that the leveling unit includes a lifting rod, the lifting rod is fixedly connected to the top surface of the support foot, a sleeve rod is slidably sleeved on the surface of the lifting rod, a threaded rod is threadedly connected to the inside of the lifting rod, and the surface of the sleeve rod is fixedly connected to the inside of the limiting plate.

[0010] By adopting the above technical solution, the sleeve rod is designed to limit the movement of the lifting rod, while the threaded rod guides the movement of the lifting rod. The thread pitch of the threaded rod is 0.5mm. The friction of the screw nut with a small pitch can effectively prevent the screw from loosening in the non-driving state, giving the screw nut a self-locking capability.

[0011] A further improvement of this utility model is that: one end of the threaded rod is fixedly connected to a bevel gear, one side of the bevel gear is meshed with a bevel gear, one side of the bevel gear is fixedly connected to a rotating rod, the surface of the rotating rod is rotatably connected to the inside of the sleeve rod, the surface of the rotating rod is rotatably connected to the inside of the lifting rod, and a horizontal bubble is provided on one side of the rotating rod.

[0012] By adopting the above technical solution, the setting of bevel gear one, bevel gear two, rotating rod and horizontal bubble makes it easy to level the limit rod according to the horizontal position, and at the same time, two angles can be adjusted on one side.

[0013] A further improvement of the present invention is that the storage unit includes a fixing frame, the fixing frame is fixedly connected to one side of the limiting block, the fixing frame is rotatably connected to a limiting rod inside, and the limiting rod has a positioning hole inside.

[0014] By adopting the above technical solution, the positioning holes inside the fixing frame facilitate the storage of the limiting rod while reducing the storage volume.

[0015] A further improvement of this utility model is that: a T-shaped rod is slidably connected inside the positioning hole, the surface of the T-shaped rod is slidably connected inside the fixing frame, a spring is sleeved on the outside of the T-shaped rod, one end of the spring is fixedly connected to one side of the T-shaped rod, and the other end of the spring is fixedly connected to one side of the fixing frame.

[0016] By adopting the above technical solution, the T-shaped rod and spring are used to quickly and easily fix the limiting rod for storage and use.

[0017] A further improvement of the present invention is that the lifting unit includes a second motor, which is bolted to the inside of the limiting rod. The output end of the second motor is fixedly sleeved with a second threaded rod, and a moving rod is threadedly connected to the surface of the second threaded rod.

[0018] By adopting the above technical solution, the setting of motor two, threaded rod two, and moving rod achieves the effect of facilitating height adjustment during the detection and monitoring process. The thread pitch of threaded rod two is 0.5mm. The friction of the small-pitch screw nut can effectively prevent the screw from loosening in the non-drive state, so that the screw nut has self-locking capability.

[0019] A further improvement of this utility model is that: the two sides of the moving rod are slidably disposed inside the limiting rod, the moving rod is internally threaded with a threaded rod three, the surface of the threaded rod three is threaded with an infrared rangefinder, one end of the threaded rod three is fixedly sleeved with a motor three, and one side of the motor three is bolted to the top surface of the moving rod.

[0020] By adopting the above technical solution, the setting of threaded rod three and motor three achieves the effect of facilitating precise adjustment of the position of the infrared rangefinder, further improving the detection and monitoring effect. The thread pitch of threaded rod two is 0.5mm. The friction of the small-pitch screw nut can effectively prevent the screw from loosening in the non-drive state, so that the screw nut has self-locking capability.

[0021] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0022] 1. This utility model provides a core sampling detection and monitoring device for pile foundations. Through the setting of a limiting plate, limiting groove, limiting block, gear one, gear two, and motor one, it achieves the effect of facilitating the rotation and detection of the storage unit, further improving the detection effect. At the same time, the setting of the limiting plate facilitates the isolation of external mud and sand, avoiding the problem of mud and sand causing gear one and gear two to jam and wear during use, further improving the service life and reducing costs. The setting of the sleeve rod facilitates the limiting of the movement of the lifting rod, and the setting of the threaded rod one facilitates the guiding effect of the movement of the lifting rod.

At the same time, it can be adjusted at two corners on one side. The positioning hole inside the fixing frame facilitates the storage of the limiting rod and reduces the storage volume. The arrangement of threaded rod three and motor three facilitates the precise adjustment of the position of the infrared rangefinder, further improving the detection and monitoring effect.

[0031] Example 1

[0032] like Figure 1-5As shown, this utility model provides a core sampling and monitoring device for pile foundations, including a support leg 1. A leveling unit 2 is provided on the top surface of the support leg 1. A rotating unit 3 is provided on one side of the leveling unit 2.

One end of the spring 45 is fixedly connected to one side of the T-shaped rod 44, and the other end of the spring 45 is fixedly connected to one side of the fixing frame 41. At the same time, the control motor 36 drives the gear 35 to mesh with the gear 34, and drives the limiting block 33 to rotate the fixing frame 41 under the limitation of the limiting groove 32. At the same time, the limiting rod 42 is rotated for detection. After use, the T-shaped rod 44 is pulled out from the inside of the positioning hole 43, and the limiting rod 42 is rotated to prevent it from entering the limiting plate 31. The T-shaped rod 44 is then placed back into the positioning hole 43 on the other side. The elasticity of the spring 45 completes the fixation of the limiting rod 42, while reducing the storage volume.

[0033] Example 2

[0034] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the leveling unit 2 includes a lifting rod 21, which is fixedly connected to the top surface of the support foot 1. A sleeve rod 22 is slidably sleeved on the surface of the lifting rod 21. A threaded rod 23 is threadedly connected inside the lifting rod 21. The surface of the sleeve rod 22 is fixedly connected to the inside of the limiting plate 31. A bevel gear 24 is fixedly connected to one end of the threaded rod 23. A bevel gear 25 is meshed with one side of the bevel gear 24. A bevel gear 25 is fixedly connected to one side of the bevel gear 25. There is a rotating rod 26, the surface of which is rotatably connected to the inside of the sleeve rod 22. The surface of the rotating rod 26 is rotatably connected to the inside of the lifting rod 21. A horizontal bubble 27 is provided on one side of the rotating rod 26. When the device is moved to the core sampling position of the pile foundation, the rotating rod 26 is rotated on one side of the limiting plate 31, which drives the bevel gear 25 to rotate. At the same time, the threaded rod 23 on one side of the bevel gear 24 drives the lifting rod 21 to adjust the horizontal position of the limiting plate 31 according to the action of the horizontal bubble 27 under the limitation of the sleeve rod 22.

[0035] Example 3

[0036] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the lifting unit 5 includes a second motor 51, model number Y100L-2. The second motor 51 is bolted to the inside of the limiting rod 42. A threaded rod 52 is fixedly sleeved at the output end of the second motor 51.

Simultaneously, the control motor 56 drives the infrared distance measuring instrument 55 to move the threaded rod 54 under the limit of the moving rod 53, so as to further adjust the monitoring and detection position.

[0037] The working principle of the core sampling and monitoring device for this pile foundation will be explained in detail below.

[0038] like Figure 1-5As shown, by moving the device to the core sampling position of the pile foundation, the rotating rod 26 on one side of the limiting plate 31 drives the bevel gear 25 to rotate, and at the same time drives the threaded rod 23 on one side of the bevel gear 24 to drive the lifting rod 21. Under the limitation of the sleeve rod 22, the supporting foot 1 adjusts the horizontal position of the limiting plate 31 according to the action of the horizontal bubble 27. After the adjustment is completed, the control motor 51 drives the threaded rod 52 to rotate, and at the same time drives the moving rod 53 to adjust according to the required height under the limitation of the limiting rod 42. At the same time, the control motor 56 drives the infrared rangefinder 55 under the limitation of the moving rod 53 to drive the threaded rod. The third 54 is moved to further adjust the position of the monitoring and detection. At the same time, the control motor 36 drives the gear 2 35 to mesh with the gear 1 34. Simultaneously, the limit block 33 drives the fixed frame 41 to rotate under the limit groove 32. At the same time, the limit rod 42 rotates for detection. After use, the T-shaped rod 44 is pulled out from the inside of the positioning hole 43. At the same time, the limit rod 42 is rotated to prevent it from being inside the limit plate 31. The T-shaped rod 44 is then placed back into the positioning hole 43 on the other side. The elasticity of the spring 45 completes the fixation of the limit rod 42, while reducing the storage volume.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
