[0002] The pile foundation is composed of a pile foundation and a bearing platform connected to the top of the pile. If the entire pile body is buried in the soil and the bottom surface of the bearing platform contacts the soil, it is called a low-bearing platform pile foundation; if the upper part of the pile exposes above the ground and the bottom of the bearing platform is above the ground, it is called a high-bearing platform pile foundation. Building pile foundations are usually low-bearing platform pile foundations and are widely used in projects such as high-rise buildings, bridges, and high-speed rails. When constructing a pile foundation, it is necessary to drill holes at the construction location, then install a reinforcement mold bundled with steel bars or steel pipes into the existing installation holes, and finally pour concrete into the reinforced mold.

The operation box is fixedly arranged on the inner wall of the bottom of the main body box. The clamping and fixing component is arranged in the main body box. The clamping and fixing component includes a servo motor, a worm, a bearing, a worm gear, a driving gear, a rack, a horizontal sliding column, a connecting rod, and a clamping block. The outer ring of the bearing is fixedly arranged on the inner wall of the main body box. One end of the worm is fixedly arranged on the inner ring of the bearing. The servo motor is fixedly arranged on the inner wall of the main body box. The output end of the servo motor is fixedly connected to the end of the worm away from the bearing. The worm gear rotates on the inner wall of the main body box. The worm gear meshes with the worm. The driving gear is fixedly arranged on the worm gear. The utility model belongs to the technical field of engineering detection, and specifically is a device for detecting the strength of bridge pile foundation concrete with a large applicable range and can avoid residues splashing everywhere.

[0004] Currently, when detecting the strength of bridge pile foundation concrete, it is usually necessary to detect multiple samples. However, after detecting a group of samples with the above device, it is necessary to take out and clean the crushed samples before the strength of the next group of samples can be detected. It is difficult to continuously detect the bridge pile foundation concrete, so the detection efficiency is low, and it is difficult to clean the crushed concrete blocks, resulting in an increase in detection time, a long overall detection process, and poor practicability. Content of the Utility Model

This technical solution solves the problems that it is difficult to continuously detect the bridge pile foundation concrete, resulting in low detection efficiency, and it is difficult to clean the crushed concrete blocks, leading to an increase in detection time and a long overall detection process.

[0022] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4 As shown, a device for detecting the concrete strength of bridge pile foundations includes a collection tank 1. A support plate 102 is fixedly connected to the middle of the upper end of the collection tank 1. A driving mechanism 2 is installed at the upper end of the collection tank 1. The driving mechanism 2 includes two groups of screws 203. The screws 203 are rotatably connected to the upper end of the collection tank 1 through bearings. Two groups of feeding mechanisms 3 are installed at the upper end of the support plate 102. The feeding mechanism 3 includes a placement plate 302. The placement plate 302 is slidably connected to the upper end of the support plate 102. Two groups of baffles 104 are fixedly connected to the middle of the upper end of the collection tank 1. A detection mechanism 4 is installed outside the baffles 104. The detection mechanism 4 includes a lower pressing plate 403. The lower pressing plate 403 is slidably connected between the two groups of baffles 104. A pressure sensor 404 is fixedly connected to the lower end of the lower pressing plate 403. A breaker hammer 405 is fixedly connected to the lower end of the pressure sensor 404.

[0025] In this solution, the driving mechanism 2 can drive two groups of placing plates 302 to move left and right simultaneously. The initial positions of the two groups of placing plates 302 are respectively at the left and right ends of the upper surface of the support plate 102, and the two groups of placing plates 302 are used to place concrete samples. The support plate 102 can support the two groups of placing plates 302. When testing the strength of concrete, the concrete sample is placed on the upper end of one of the placing plates 302 by an external lifting mechanism, and the driving mechanism 2 drives the two groups of placing plates 302 to move to the right, moving one of the placing plates 302 to the right between the two baffles 104, and the other placing plate 302 is located inside the collection tank 1, as Figure 2 shown;

[0026] Furthermore, one of the placing plates 302 drives the concrete sample to move directly below the breaker 405. The lower pressing plate 403 can drive the pressure sensor 404 and the breaker 405 to move downward, so that the breaker 405 applies pressure to the concrete sample, and the pressure sensor 404 records the pressure received by the concrete sample, thereby detecting the quality of the concrete sample and completing the detection of the first group of concrete samples.

[0027] Furthermore, after the detection of the first group of concrete samples is completed, the lower pressing plate 403 drives the pressure sensor 404 and the breaker 405 to move upward to reset, and the driving mechanism 2 moves one of the placing plates 302 to the left end of the support plate 102, and the other placing plate 302 moves from inside the collection tank 1 to the right end of the upper surface of the support plate 102, and the next group of samples is placed on the upper end of the other placing plate 302. Then, the driving mechanism 2 drives the two groups of placing plates 302 to move to the left again. At this time, one of the placing plates 302 moves into the collection tank 1, and the tested concrete sample and the broken concrete blocks are transported into the collection tank 1 for cleaning, so that one of the placing plates 302 remains clean and waits for the next feeding operation. Moreover, the other placing plate 302 moves directly below the breaker 405, so as to detect the strength of the second group of samples. While the two groups of placing plates 302 can detect one group of concrete samples, they can clean the samples after the previous group of detections, so as to facilitate the placement of the next group of concrete samples. Through the continuous left and right movement of the two groups of placing plates 302, the feeding, detection and cleaning operations of the concrete samples can be continuously completed, ensuring the continuity of the concrete sample detection, reducing the time required for the concrete detection process, and increasing the efficiency of the concrete detection.

[0028] Embodiment 2

[0029] Please refer to Figure 3As shown in the figure, the feeding mechanism 3 further includes a moving frame 301. The placing plate 302 is rotatably connected to the inside of the moving frame 301. Four groups of moving blocks 303 are fixedly installed at the lower end of the moving frame 301. Two moving blocks 303 in each group are threadedly connected to the outside of the screw rod 203.

[0030] In this solution, the screw rod 203 can rotate, so as to drive the moving frame 301 to move left and right through the moving blocks 303, and then drive the placing plate 302 to move left and right. When the moving frame 301 moves to the right end or the left end of the collection tank 1, the concrete sample presses the placing plate 302 to rotate downward by its own gravity, and then the placing plate 302 rotates to be perpendicular to the moving frame 301, so as to convey the concrete sample after the test into the collection tank 1, which is convenient for cleaning the concrete sample after the test.

[0031] Embodiment 3

[0032] Please refer to Figure 2 As shown in the figure, the driving mechanism 2 further includes a bidirectional motor 201. The bidirectional motor 201 is fixedly installed at the right end of the collection tank 1 through a motor seat. The output ends on both sides of the bidirectional motor 201 are fixedly connected with first bevel gears 202. The right end of the screw rod 203 penetrates through the bearing seat and is fixedly connected with a second bevel gear 204 meshing with the first bevel gear 202.

[0033] In this solution, the bidirectional motor 201 is electrically connected to an external power supply. When the bidirectional motor 201 starts, it can drive the two first bevel gears 202 to rotate, and then drive the screw rod 203 to rotate through the two second bevel gears 204.

[0034] Embodiment 4

[0035] Please refer to Figure 4 As shown in the figure, the detection mechanism 4 further includes a mounting frame 401. The mounting frame 401 is fixedly connected to the upper end of the baffle 104. Two hydraulic cylinders 402 are fixedly connected to the lower end of the mounting frame 401. The output ends of the hydraulic cylinders 402 are fixedly connected with a lower pressing plate 403.

[0036] In this solution, the hydraulic cylinder 402 can drive the lower pressing plate 403 to move up and down.

[0037] Embodiment 5

[0038] Please refer to Figure 1 And Figure 3 As shown in the figure, feeding ports 101 are provided at both the left and right ends of the collection tank 1. Discharge inclined platforms 103 are fixedly connected to both ends of the support plate 102.

[0039] In this solution, when the moving frame 301 drives the placement plate 302 to slowly move the concrete sample to the feeding port 101 after the detection is completed, the placement plate 302 slowly rotates along the inclined surface of the discharge ramp 103. When the moving frame 301 moves directly above the feeding port 101, the placement plate 302 is perpendicular to the moving frame 301, so as to clean the detected concrete sample into the interior of the collection tank 1. After the cleaning is completed, the moving frame 301 moves in the reverse direction, causing the placement plate 302 to rotate along the discharge ramp 103 again until the entire placement plate 302 moves to the upper end of the support plate 102, and the placement plate 302 is in a horizontal state with the moving frame 301, so that the next group of samples can be placed on the upper end of the placement plate 302.

[0040] The working principle and usage process of the present utility model are as follows: First, when detecting the strength of concrete, the concrete sample is placed on the upper end of one group of placement plates 302 through an external lifting mechanism, and the driving mechanism 2 drives the two moving frames 301 to move one group of placement plates 302 to directly below the breaker hammer 405 to the right. At this time, the hydraulic cylinder 402 is activated to press down the breaker hammer 405 to apply pressure to the concrete sample, and the pressure sensor 404 records the pressure. After the detection is completed, the breaker hammer 405 moves upward to reset. The driving mechanism 2 drives the other group of placement plates 302 to move from the interior of the collection tank 1 to the upper right end of the support plate 102, and the next group of samples is placed on the upper end of the other group of placement plates 302. Then, the driving mechanism 2 drives the two placement plates 302 to move to the left again until the concrete sample moves below the breaker hammer 405. At this time, the moving frame 301 moves directly above the left discharge port 101, and the placement plate 302 is pressed down to rotate by the self-weight of the concrete sample, so that the placement plate 302 rotates to be perpendicular to the moving frame 301, thereby transporting the detected concrete sample into the interior of the collection tank 1.

Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments.
