Description

A high strain testing support for pile foundations Technical Field

[0001] This utility model relates to the field of foundation pile testing technology, specifically to a high-strain testing support for pile foundations. Background Technology

[0002] A deep foundation consisting of piles and a pile cap connecting the pile tops, or a single-pile foundation connecting a column and piles, is simply called a pile foundation. If the entire pile is embedded in the soil and the bottom of the pile cap is in contact with the soil, it is called a low-pile-cap pile foundation; if the upper part of the pile is exposed above the ground and the bottom of the pile cap is above the ground, it is called a high-pile-cap pile foundation. Building pile foundations are usually low-pile-cap pile foundations. Pile foundations are widely used in high-rise buildings.

[0003] However, existing high strain testing supports for pile foundations cannot be height-adjusted, making it impossible to meet the needs of different heights. In addition, the supports are mostly placed on the surface of the pile foundation during use, which may cause the supports to shift when the hammer is dropped. Summary of the Invention

[0004] The purpose of this utility model is to provide a high strain testing support for pile foundations to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A high-strain testing bracket for pile foundations includes a support frame, an adjustment mechanism at the top of the support frame, and a fixing mechanism at the bottom of the support frame.

[0007] The adjustment mechanism includes a support platform, which is fixedly mounted on the surface of a support frame. A fixed frame is fixedly mounted on the top of the support platform, and a motor is fixedly mounted on the surface of the fixed frame. A first synchronous pulley is fixedly mounted on the output end of the motor. A first synchronous belt is movably connected to the surface of the first synchronous pulley, and a second synchronous pulley is movably connected to the surface of the first synchronous belt. A third synchronous pulley is fixedly mounted on the bottom end of the second synchronous pulley, and a second synchronous belt is movably connected to the surface of the third synchronous pulley. A fourth synchronous pulley is movably connected to the surface of the second synchronous belt, and the second synchronous belt is movably mounted inside the support platform.

[0008] A further improvement of the present invention is that: a connecting ring is fixedly installed at the top of the fixed frame, a first counterweight guide frame is fixedly installed on the inner side of the fixed frame, the first counterweight guide frame is symmetrically distributed on both sides of the fixed frame, a second counterweight guide frame is fixedly installed on the inner side of the fixed frame, the second counterweight guide frame is symmetrically distributed on both sides of the fixed frame, and a height scale is provided on the surface of the fixed frame near the second counterweight guide frame.

[0009] A further improvement of the present invention is that the adjusting mechanism further includes a threaded rod, which is fixedly installed on the surfaces of the second synchronous belt and the fourth synchronous belt pulley. An adjusting frame is threadedly connected to the surface of the threaded rod, and a fourth counterweight guide frame is fixedly installed on the surface of the adjusting frame. A third counterweight guide frame is fixedly installed on the surface of the adjusting frame.

[0010] A further improvement of the present invention is that the fixing mechanism includes a base, the base is movably mounted on the surface of the support frame, a fixing pile is fixedly installed at the bottom end of the base, four sets of fixing piles are provided, the fixing piles are evenly distributed around the base, a level is fixedly installed at the bottom end of the base, and a fixing groove is provided inside the base.

[0011] A further improvement of the present invention is that the fixing mechanism further includes a threaded cylinder, which is movably installed inside the fixing groove. The threaded cylinder is threadedly connected to a threaded column inside the threaded cylinder, and a rotating rod is fixedly installed on the surface of the threaded column.

[0012] A further improvement of this utility model is that: a fixed rod is movably installed inside the threaded column, the fixed rod is fixedly installed inside the threaded cylinder, a movable disc is movably installed on the surface of the fixed rod, and a spring is sleeved on the surface of the movable disc.

[0013] A further improvement of this utility model is that: a connecting rod is movably mounted on the surface of the movable disc, a locking rod is movably mounted on one end of the connecting rod, the locking rod is movably mounted inside the threaded cylinder, and the locking rod is adapted to the fixing groove.

[0014] 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:

[0015] 1. This utility model provides a high-strain detection bracket for pile foundations, employing a fixed frame, connecting ring, first counterweight guide frame, second counterweight guide frame, threaded rod, motor, first synchronous pulley, support platform, first synchronous belt, second synchronous pulley, third synchronous pulley, second synchronous belt, fourth synchronous pulley, height scale, adjusting frame, third counterweight guide frame, and fourth counterweight guide frame in coordination. The fixed frame is suspended by the connecting ring. The first synchronous pulley on the motor surface drives the first synchronous belt to rotate, the second synchronous pulley rotates, driving the third synchronous pulley to rotate, and the second synchronous belt causes multiple sets of fourth synchronous pulleys to rotate synchronously. The second synchronous belt passes through the support platform, maintaining the stability of the second synchronous belt while preventing external interference. The synchronous rotation of the threaded rods on the surfaces of the synchronous pulleys and the fourth synchronous pulley drives the adjusting frame to move upward. The threads are all wedge-shaped threads with a 30-degree angle, thus generating self-locking capability. The material is high-strength steel, which improves its load-bearing capacity and prevents wear. The first and second hammer guide frames clamp the adjusting frame to prevent it from moving upward. The width of the second hammer guide frame is smaller than that of the first hammer guide frame, allowing the hammer to be observed through the gap and its height to be confirmed by a height gauge. When the hammer falls downward, the first, second, fourth, and third hammer guide frames guide the direction of the hammer's fall, preventing deviation and improving the adaptability of the device.

[0016] 2. This utility model provides a high-strain testing bracket for pile foundations, which employs a base, level, fixed pile, fixed groove, threaded cylinder, threaded column, rotating rod, fixed rod, movable disc, spring, connecting rod, and clamping rod. The fixed pile is fixed to the ground around the pile foundation, and the level is achieved using the level. The support frame is aligned with the base and placed. The threaded cylinder is then inserted into the fixed groove, and the rotating rod is turned, causing the threaded column to push the movable disc downwards along the fixed rod. Simultaneously, the spring compresses, and the connecting rod at the bottom of the movable disc pushes the clamping rod outwards, engaging with the fixed groove to complete the fixation. This device can fix the device without damaging the pile foundation, ensuring the accuracy of the test data and improving the adaptability of the device. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] As shown in Figures 1-6, this utility model provides a high-strain detection bracket for pile foundations, including a support frame 1. An adjustment mechanism 2 is provided at the top of the support frame 1, and a fixing mechanism 3 is provided at the bottom of the support frame 1. The adjustment mechanism 2 includes a support platform 208, which is fixedly installed on the surface of the support frame 1. A fixing frame 201 is fixedly installed at the top of the support platform 208. A motor 206 is fixedly installed on the surface of the fixing frame 201. A first synchronous pulley 207 is fixedly installed at the output end of the motor 206. A first synchronous belt 209 is movably connected to the surface of the first synchronous pulley 207. A second synchronous pulley 210 is movably connected to the surface of the first synchronous belt 209. A third synchronous pulley 211 is fixedly installed at the bottom of the second synchronous pulley 210. A second synchronous belt 212 is movably connected to the surface of the third synchronous pulley 211. A fourth synchronous pulley 213 is movably connected to the surface of the second synchronous belt 212. The synchronous belt 212 is movably installed inside the support platform 208. A connecting ring 202 is fixedly installed at the top of the fixed frame 201. A first counterweight guide frame 203 is fixedly installed on the inner side of the fixed frame 201. The first counterweight guide frame 203 is symmetrically distributed on both sides of the fixed frame 201. A second counterweight guide frame 204 is fixedly installed on the inner side of the fixed frame 201. The second counterweight guide frame 204 is symmetrically distributed on both sides of the fixed frame 201. A height scale 214 is provided on the surface of the fixed frame 201 near the second counterweight guide frame 204. The adjustment mechanism 2 also includes a threaded rod 205. The threaded rod 205 is fixedly installed on the surface of the second synchronous belt 212 and the fourth synchronous pulley 213. An adjustment frame 215 is threadedly connected to the surface of the threaded rod 205. A fourth counterweight guide frame 217 is fixedly installed on the surface of the adjustment frame 215. A third counterweight guide frame 216 is fixedly installed on the surface of the adjustment frame 215.

[0027] In this embodiment, the fixed frame 201 is lifted by the connecting ring 202. The first synchronous pulley 207 on the surface of the motor 206 drives the first synchronous belt 209 to rotate. The rotation of the second synchronous pulley 210 drives the third synchronous pulley 211 to rotate. The second synchronous belt 212 causes multiple sets of fourth synchronous pulleys 213 to rotate synchronously. The second synchronous belt 212 passes through the support platform 208, which maintains the stability of the second synchronous belt 212 and avoids external interference to the second synchronous belt 212. The threaded rods 205 on the surfaces of the third synchronous pulley 211 and the fourth synchronous pulleys 213 rotate synchronously, causing the adjusting frame 215 to move upward. The threads of the threaded rods 205 are all wedge-shaped threads with a 30-degree angle. The self-locking capability and the use of high-strength steel enhance its load-bearing capacity while preventing wear. The first hammer guide frame 203 and the second hammer guide frame 204 clamp the adjusting frame 215 to prevent it from moving upwards. The width of the second hammer guide frame 204 is smaller than that of the first hammer guide frame 203, allowing the hammer to be observed through the gap and its height to be confirmed by the height scale 214. When the hammer falls downwards, the first hammer guide frame 203, the second hammer guide frame 204, the fourth hammer guide frame 217, and the third hammer guide frame 216 guide the hammer's falling direction to prevent deviation and improve the adaptability of the device.

[0028] Example 2

[0029] As shown in Figures 1-6, based on Embodiment 1, this utility model provides a technical solution: Preferably, the fixing mechanism 3 includes a base 301, which is movably mounted on the surface of the support frame 1. A fixing post 303 is fixedly installed at the bottom end of the base 301. Four sets of fixing posts 303 are evenly distributed around the base 301. A level 302 is fixedly installed at the bottom end of the base 301. A fixing groove 304 is provided inside the base 301. The fixing mechanism 3 also includes a threaded cylinder 305, which is movably mounted inside the fixing groove 304. The internal threaded connection of the cylinder 305 is a threaded post 306. A rotating rod 307 is fixedly installed on the surface of the threaded post 306. A fixing rod 308 is movably installed inside the threaded post 306. The fixing rod 308 is fixedly installed inside the threaded cylinder 305. A movable disc 309 is movably installed on the surface of the fixing rod 308. A spring 310 is sleeved on the surface of the movable disc 309. A connecting rod 311 is movably installed on the surface of the movable disc 309. A locking rod 312 is movably installed at one end of the connecting rod 311. The locking rod 312 is movably installed inside the threaded cylinder 305 and is adapted to the fixing groove 304.

[0030] In this embodiment, by fixing the fixed pile 303 to the ground around the pile foundation and leveling it with the leveler 302, the support frame 1 is aligned with and placed on the base 301. At this time, the threaded cylinder 305 is inserted into the fixing groove 304, and the rotating rod 307 is turned so that the threaded column 306 pushes the movable disk 309 downward along the fixed rod 308. While the spring 310 is compressed, the connecting rod 311 at the bottom of the movable disk 309 pushes the locking rod 312 outward to engage with the fixing groove 304 and complete the fixation. This device can fix the device without damaging the pile foundation, ensuring the accuracy of the detection data and improving the adaptability of the device.

[0031] The working principle of the high strain testing support for this pile foundation will be explained in detail below.

[0032] As shown in Figures 1-6, by fixing the fixed piles 303 to the ground around the pile foundation, leveling is achieved using the leveler 302, and the support frame 1 is aligned and placed with the base 301. Then, the threaded cylinder 305 is inserted into the fixing groove 304, and the rotating rod 307 is turned, causing the threaded column 306 to push the movable disc 309 downwards along the fixing rod 308. Simultaneously, the spring 310 compresses, and the connecting rod 311 at the bottom of the movable disc 309 pushes the locking rod 312 outwards, engaging with the fixing groove 304 to complete the fixation. This device can fix the device without damaging the pile foundation, ensuring the accuracy of the test data. The fixing frame 201 is lifted by the connecting ring 202. The first synchronous pulley 207 on the surface of the motor 206 drives the first synchronous belt 209 to rotate, the second synchronous pulley 210 rotates, driving the third synchronous pulley 211 to rotate, and the second synchronous belt 212 drives multiple sets of fourth synchronous pulleys 213 to rotate. The second synchronous belt 212 rotates synchronously, passing through the support platform 208. This ensures the stability of the second synchronous belt 212 while preventing external interference. The threaded rods 205 on the surfaces of the third synchronous pulley 211 and the fourth synchronous pulley 213 rotate synchronously, causing the adjusting frame 215 to move upward. The first hammer guide frame 203 and the second hammer guide frame 204 clamp the adjusting frame 215 to prevent it from moving upward. The width of the second hammer guide frame 204 is smaller than that of the first hammer guide frame 203, allowing the hammer to be observed through the gap and its height to be confirmed by the height scale 214. When the hammer falls downward, the first hammer guide frame 203, the second hammer guide frame 204, the fourth hammer guide frame 217, and the third hammer guide frame 216 guide the hammer's falling direction, preventing deviation and improving the adaptability of the device.

[0033] 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.
