Description

Technical Field

[0001] This utility model relates to the field of acoustic logging pipe pile head technology, specifically to an acoustic logging pipe pile head protection device. Background Technology

[0002] A sonic logging tube is a type of pipe used in construction engineering for ultrasonic testing of foundation piles. The pile head of the sonic logging tube refers to the part of the sonic logging tube at the top of the pile body. It is a key part that connects the sonic logging tube with the pile top and external testing equipment. It is an indispensable sonic testing tube. The quality of a pile can be detected by using a sonic logging tube. The sonic logging tube is the channel through which the probe enters the interior of the pile body when performing ultrasonic testing on cast-in-place piles.

[0003] The present invention, CN 221941459 U, discloses a pile head protection device for sonic logging pipes, which solves the problem in the prior art that the pile head protection of sonic logging pipes is only done by plugging the upper end of the sonic logging pipe with a plug to prevent cement from entering the sonic logging pipe. However, when the sonic logging pipe is hit by an object, the part of the sonic logging pipe exposed above the cement pile foundation is bent, thus making it impossible to insert the probe into the sonic logging pipe when performing ultrasonic testing.

[0004] This sonic logging pipe pile head protection device solves the problem of existing technology where the pile head protection of sonic logging pipes is simply blocked at the top of the pipe with a plug to prevent cement from entering. However, the columnar shell on the device cannot be fixed inside the reinforcing steel ring and cannot limit the position of the sonic logging pipe. When the sonic logging pipe is hit, it can shake and be damaged at the same time. Therefore, it needs to be improved. Utility Model Content

[0015] The sonic logging pipe pile head protection device, through the setting of a limiting mechanism, when it is necessary to limit the position of the protective frame, uses a first threaded rod, limiting strip, lifting plate, sliding rod, sliding plate, rotating disk, hollow plate, spring, sliding plate and inclined plate to work together to allow the reinforcing bar to slide into the inside of the limiting strip, thereby limiting the position of the protective frame. When an impact occurs, the impact force will be transmitted to the reinforcing cage through the limiting strip, and the limiting strip and the reinforcing cage will bear most of the impact force, preventing damage to the sonic logging pipe body.

An inclined plate 401 is fixedly connected to the outer side of the sliding plate 49.

[0028] Furthermore, there are two slide rods 44, which are fixedly connected to the top left and right sides of the lifting plate 43 respectively, and are slidably connected to the inner side of the slide plate 45 respectively. The slide rods 44 can limit the lifting plate 43, making the lifting plate 43 more stable during the lifting process.

[0029] Furthermore, a limiting groove corresponding to the movement trajectory of the sliding plate 49 is provided on the inner side of the skateboard 45, and the sliding plate 49 is slidably connected to the inside of the limiting groove. Through the limiting groove, the sliding plate 49 can slide inside the skateboard 45, making the sliding plate 49 more stable during movement.

[0030] Furthermore, a rectangular groove corresponding to the position of the inclined plate 401 is provided on the inner side of the hollow plate 47, and the inclined plate 401 is inserted into the rectangular groove. Through the rectangular groove, the inclined plate 401 can be inserted into the hollow plate 47 to limit the position of the slide plate 45. Example

[0031] Please see Figure 1-4 Furthermore, based on Embodiment 1, the clamping mechanism 3 further includes a second threaded rod 33, which is threadedly connected to the right side of the protective frame 1. A first clamping plate 31 is rotatably connected to the left side of the second threaded rod 33. A sliding rod 32 is fixedly connected to the right side of the first clamping plate 31. A limiting plate 34 is fixedly connected to the right side of the sliding rod 32. A second rack 302 is fixedly connected to the front of the limiting plate 34. A gear 35 meshes with the top of the second rack 302. A support plate 36 is rotatably connected to the front of the gear 35. The support plate 36 is fixedly connected to the front of the protective frame 1. The back end of the gear 35 is rotatably connected to the front of the protective frame 1. A first rack 38 meshes with the top of the gear 35. A linkage plate 301 is fixedly connected to the left side of the first rack 38. A linkage rod 39 is fixedly connected to the right side of the linkage plate 301. A second clamping plate 37 is fixedly connected to the inner side of the linkage rod 39.

[0032] Furthermore, a circular hole is provided on the inner side of the protective frame 1, corresponding to the position of the sliding rod 32 and the linkage rod 39, and the sliding rod 32 and the linkage rod 39 are slidably connected to the inner side of the circular hole. Through the circular hole, the sliding rod 32 and the linkage rod 39 can slide inside the protective frame 1.

[0033] Furthermore, the first clamping plate 31 and the second clamping plate 37 are disposed on the outside of the sonic logging tube body 2, and the inner sides of the first clamping plate 31 and the second clamping plate 37 are in close contact with the outer side of the sonic logging tube body 2. The first clamping plate 31 and the second clamping plate 37 can clamp and fix the sonic logging tube body 2, making it less likely to shake or be damaged by collision.

[0034] In actual operation, when this device is used, the sliding plate 45 is pulled according to the position of the steel bar, so that the sliding plate 45 can drive the inclined plate 401 to move. When the inclined plate 401 is blocked by the hollow plate 47, the inclined plate 401 can squeeze the spring 48 through the sliding plate 49. When the hollow plate 47 does not squeeze the inclined plate 401, the elastic force of the spring 48 can drive the sliding plate 49 to move the inclined plate 401, so that the inclined plate 401 can be inserted into the inner side of the hollow plate 47 to limit the position of the sliding plate 45. When the sliding plate 45 moves to the appropriate position, the rotating disk 46 drives the first threaded rod 41 to rotate, so that the first threaded rod 41 drives the limiting strip 42 to move through the lifting plate 43, so that the steel bar can slide into the inner side of the limiting strip 42 to limit the position of the protective frame 1. When an impact occurs, the impact force will be transmitted to the steel cage through the limiting strip 42. The limiting strip 42 and the steel cage bear most of the impact force to prevent the sounding pipe body 2 from being damaged.

[0035] When protection of the sonic logging pipe body 2 is required, the protective frame 1 is slid into the periphery of the sonic logging pipe body 2, and the second threaded rod 33 is rotated to move the first clamping plate 31. When the first clamping plate 31 moves, the sliding rod 32 drives the limiting plate 34 and the second rack 302 to move, and the second rack 302 drives the first rack 38 to move through the gear 35. The first rack 38 can drive the linkage rod 39 to move through the linkage plate 301, and the linkage rod 39 can drive the second clamping plate 37 to move. The first clamping plate 31 and the second clamping plate 37 can clamp and protect the sonic logging pipe body 2, making it less susceptible to collision damage.
