Description

Technical Field

[0001] This utility model belongs to the technical field of quality testing devices, and in particular relates to a quality testing device for building pile foundation drilling. Background Technology

[0002] With the accelerated pace of urbanization, various large-scale construction projects are emerging like mushrooms after rain. As the foundation support structure of a building, the construction quality of building pile foundations directly affects the stability and safety of the entire building. In the construction of building pile foundations, the quality of hole formation is an extremely critical link, which has a decisive impact on the bearing capacity and settlement performance of the pile foundation. Therefore, high-precision building pile foundation hole formation quality testing devices are essential for ensuring the quality of pile foundation construction and ensuring the safety and reliability of building projects.

[0003] However, existing building pile foundation hole forming quality testing devices may experience rope displacement due to wind force during use, affecting the depth inspection and causing a large deviation between the inspection results and the actual data, resulting in reduced construction quality. Utility Model Content

[0004] The purpose of this invention is to provide a device for testing the quality of pile foundation drilling. By setting up a depth detection mechanism, it solves the problem that the position of the rope may shift due to wind, affecting the depth detection and causing a large deviation between the test results and the actual data, which leads to a reduction in construction quality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a device for detecting the quality of hole formation in building pile foundations, including a base, on which a depth detection mechanism and a fixing mechanism are provided;

[0007] The depth detection mechanism includes a wire feeding assembly and an anti-sway assembly. The wire feeding assembly includes two brackets fixedly connected to the top of the base. A rotating shaft is rotatably connected between the two brackets. The front side of the rotating shaft passes through the bracket located on the front side and extends outward. A wire feeding wheel is fixedly connected to the outer wall of the rotating shaft. A motor bracket is fixedly connected to the outer wall of the bracket located on the front side. A motor is fixedly connected to the motor bracket. The output shaft of the motor is fixedly connected to the rotating shaft through a coupling. The fixing mechanism includes rectangular plates that are fixedly connected to the outer walls of the front and rear sides of the base.

[0008] Furthermore, the base is rotatably connected to several casters, and a large fixed rod is fixedly connected between the two brackets. A lead-line wheel is rotatably connected to the outer wall of the large fixed rod, and a rope is wound on the pay-off wheel. The side of the rope away from the pay-off wheel is in contact with the lead-line wheel.

[0009] Furthermore, the anti-sway component includes a circular counterweight fixedly connected to the bottom of the rope. Several hinge blocks are fixedly connected to the outer wall of the circular counterweight. Each of the several hinge blocks is hinged with a hinge rod. Each of the several hinge rods is fixedly connected to a fixed bracket on the side away from the several hinge blocks.

[0010] Furthermore, each of the fixed supports is rotatably connected to a small fixed rod on the side away from the hinge rods. Rollers are fixedly connected to the outer walls of the small fixed rods. Hinge blocks II are fixedly connected to the outer walls of the hinge rods and the top of the circular counterweight. Fixed blocks are hingedly provided on each of the hinge blocks II.

[0011] Furthermore, telescopic rods are fixedly connected to each of the fixed blocks, and springs are fitted on each of the telescopic rods. The left and right sides of each of the springs are fixedly connected to the fixed blocks respectively.

[0012] Furthermore, each of the two rectangular plates is slidably connected to two sliding rods, and each of the two rectangular plates is provided with a fixing spike at its bottom. The two fixing spikes are respectively fixedly connected to several sliding rods, and the tops of the several sliding rods are fixedly connected to a fixing plate.

[0013] Furthermore, a threaded rod is rotatably connected to the top of the rectangular plate located on the front side. The top of the threaded rod passes through the fixed plate and extends outward. The threaded rod is threadedly connected to the fixed plate, and a handle is fixedly connected to the top of the threaded rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a depth detection mechanism and starting the motor, the motor drives the wire feeding wheel to rotate via a shaft, thus feeding the rope through the lead wire wheel. The rope is then placed into the hole to be inspected via a circular counterweight at the bottom of the rope. The inner wall of the hole is pressed against the fixed brackets and hinged rods by rollers, causing several hinged rods to rotate upwards around several hinged blocks as fulcrums. This reduces the distance between the hinged rods, thereby moving the rollers on the fixed brackets to engage with the inner wall of the hole. As the hinged rods rise, they move the rollers on the fixed brackets. The movement of the springs between the fixed blocks on the second hinge block compresses the telescopic rod and the springs through the fixed blocks on the second hinge block. At this time, the springs generate elastic force under the action of the compressive force. Under the action of the spring elastic force, the rollers are made to fit against the inner wall of the hole. Under the action of the weight of the circular counterweight, the rollers on the hinge rod are driven to rotate on the inner wall of the hole. This allows the detection device to be lowered and raised quickly in a stable state, improving detection efficiency, ensuring the accuracy of detection data, reducing unnecessary repeated detection, and further improving detection efficiency.

[0016] 2. By setting up a fixing mechanism, rotating the handle counterclockwise drives the threaded rod to rotate, which in turn drives several sliding rods to move downwards on two rectangular plates via the fixing plate. This causes the fixing spikes at the bottom of the sliding rods to move, so that the fixing spikes penetrate the ground, thereby fixing the position of the device. This ensures that the detection device is accurately placed and fixed at the preset position at the wellhead, firmly locking the detection device and ensuring that it is in the correct initial position throughout the detection process. This lays the foundation for accurate detection and prevents the detection device from shaking or shifting due to external forces.

A depth detection mechanism 2 and a fixing mechanism 3 are mounted on the base 1. The depth detection mechanism 2 includes a wire-laying assembly 21 and an anti-sway assembly 22. The wire-laying assembly 21 includes two supports 211 fixedly connected to the top of the base 1. A rotating shaft 212 is rotatably connected between the two supports 211. The front side of the rotating shaft 212 passes through the front support 211 and extends outward. A wire-laying wheel 213 is fixedly connected to the outer wall of the rotating shaft 212. A motor is fixedly connected to the outer wall of the front support 211. The bracket 214 has a motor 215 fixedly connected to it. The output shaft of the motor 215 is fixedly connected to the rotating shaft 212 via a coupling. The base 1 is rotatably connected to several casters 111. A large fixed rod 216 is fixedly connected between two brackets 211. A guide wheel 217 is rotatably connected to the outer wall of the large fixed rod 216. A rope 218 is wound on the feed wheel 213. The side of the rope 218 away from the feed wheel 213 is in contact with the guide wheel 217. The anti-sway component 22 includes a circular counterweight 22 fixedly connected to the bottom of the rope 218. 1. A plurality of hinge blocks 222 are fixedly connected to the outer wall of the circular counterweight 221. Each hinge block 222 is hinged with a hinge rod 223. Each hinge rod 223 is fixedly connected to a fixed bracket 224 on the side away from the hinge blocks 222. Each fixed bracket 224 is rotatably connected to a small fixed rod 225 on the side away from the hinge rods 223. Rollers 226 are fixedly connected to the outer walls of the small fixed rods 225. The outer walls of the hinge rods 223 and the top of the circular counterweight 221 are fixedly connected. The device is equipped with a second hinge block 227, and a fixed block 228 is hinged to each of the second hinge blocks 227. Telescopic rods 229 are fixedly connected between the fixed blocks 228. Springs 2210 are sleeved on each of the telescopic rods 229. The left and right sides of the springs 2210 are fixedly connected to the fixed blocks 228. By setting up the depth detection mechanism 2, the detection device can be quickly lowered and raised in a stable state, which improves the detection efficiency, ensures the accuracy of the detection data, reduces unnecessary repeated detection, and further improves the detection efficiency.

[0028] The fixing mechanism 3 includes rectangular plates 311 fixedly connected to the front and rear outer walls of the base 1. Two sliding rods 312 are slidably connected to each of the two rectangular plates 311. Fixing spikes 313 are provided at the bottom of each of the two rectangular plates 311. The two fixing spikes 313 are fixedly connected to several sliding rods 312 respectively. Fixing plates 314 are fixedly connected to the top of several sliding rods 312. A threaded rod 315 is rotatably connected to the top of the front rectangular plate 311. The top of the threaded rod 315 passes through the fixing plate 314 and extends outward. The threaded rod 315 is threadedly connected to the fixing plate 314. A handle 316 is fixedly connected to the top of the threaded rod 315. By setting the fixing mechanism 3, the detection device is accurately placed and fixed at the preset position of the borehole opening, firmly locking the detection device and ensuring that it is in the correct initial position throughout the detection process. This lays the foundation for accurate detection and prevents the detection device from shaking or shifting due to external forces.

[0029] A specific application of this embodiment is as follows: In use, rotating the handle 316 counterclockwise drives the threaded rod 315 to rotate, thereby causing several sliding rods 312 to move downwards on the two rectangular plates 311 via the fixed plate 314. This causes the fixing spikes 313 at the bottom of the sliding rods 312 to move, so that the fixing spikes 313 penetrate the ground, thereby fixing the position of the device. Then, the motor 215 is started, and the motor 215 drives the wire feeding wheel 213 to rotate via the rotating shaft 212, thereby feeding the rope 218 through the lead wheel 217. The circular counterweight 221 at the bottom of the rope 218 puts the rope 218 into the hole to be inspected. The inner wall of the hole is squeezed by the roller 226 against the fixed bracket 224 and the hinge rod 223, thereby causing the several hinge rods 223 to move at several... The hinge block 222 rotates upwards as a fulcrum, reducing the distance between several hinge rods 223. This causes the rollers 226 on several fixed supports 224 to move, making them engage with the inner wall of the hole. When the hinge rods 223 rise, they cause the springs 2210 between the fixed blocks 228 on several hinge blocks 227 to move. The fixed blocks 228 on several hinge blocks 227 compress the telescopic rod 229 and the springs 2210. At this time, the springs 2210 generate elastic force under the action of the compressive force. Under the action of the elastic force of the springs 2210, the rollers 226 are made to fit against the inner wall of the hole. Under the action of the weight of the circular counterweight 221, the rollers 226 on the hinge rods 223 rotate on the inner wall of the hole, thereby observing the length of the rope 218 to detect the depth of the hole.
