Description

Technical Field

[0001] The utility model relates to the technical field of concrete quality detection, in particular to a concrete quality detector. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded into a whole by cementitious materials. Concrete is widely used. The main materials that make up concrete are cement, sand, stone and water. Admixtures can also be added for compounding, and the materials need to be mixed according to the ratio. In concrete construction, it is usually necessary to test the quality of concrete, so a concrete quality detector is needed.

[0003] After searching, the Chinese patent publication number is CN216978939U, which discloses a concrete quality detector for highway construction. Through the support mechanism, the motor is first controlled to rotate forward, driving the push shaft to rotate forward, thereby driving the transmission sleeve to rotate forward, and then driving the two push plates to move downward. The downward movement of the two push plates drives the two pressure plates to move downward, thereby prompting the support plates and universal wheels to expand to both sides, making it convenient for the entire detection instrument to move. By controlling the movement of the electric push rod, the detection head is driven to move downward, reducing manual operations and speeding up detection efficiency. At the same time, the spring set can reduce the shock of the detector on the buffer table, reducing the shaking of the detector during movement, thereby increasing the service life of the detector.

[0004] However, during the use of the above patent, since gravel particles used in construction are scattered on the concrete surface, the detection device is tilted to a certain extent during detection, which will lead to errors in the detection results when detecting concrete.

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] like Figure 1-Figure 5 As shown, a concrete quality detector comprises a box body 1, in which a detection mechanism 5 and a detection mechanism 7 are installed, a lifting mechanism 2 is arranged between the detection mechanism 5 and the detection mechanism 7, the lifting mechanism 2 comprises a horizontal plate 206, a leveling mechanism 3 is arranged at the bottom of the horizontal plate 206, an adjusting mechanism 4 is installed in the leveling mechanism 3, and a covering mechanism 6 is installed on the top of the box body 1.

[0026] The adjustment mechanism 4 includes two bearing plates 401, which are welded to the front and rear sides of the fixed plate 302. A worm 402 is rotatably connected to the two bearing plates 401 through a bearing. A worm wheel 403 is meshed on one side of the worm 402. The worm wheel 403 is keyed to the threaded tube 304. A turntable 404 is welded on the front side of the worm 402. The worm 402 is rotated by rotating the turntable 404, thereby driving the worm wheel 403 to rotate. The leveling mechanism 3 includes a connecting plate 301, which is welded to the bottom of the cross plate 206. A fixed plate 302 is welded to the bottom of the connecting plate 301. A fixed plate 302 is welded on one side of the fixed plate 302. The mounting block 303 has a threaded tube 304 rotatably connected to the mounting block 303 through a bearing, a threaded rod 305 is threadedly connected to the threaded tube 304, a sliding plate 306 is welded to the bottom of the threaded rod 305, and the sliding plate 306 is slidably connected to one side of the fixed plate 302. A moving wheel is installed at the bottom of the sliding plate 306 through a bracket, and the threaded tube 304 is driven to rotate by the rotation of the worm gear 403, thereby driving the threaded rod 305 to rise and fall, and then driving the sliding plate 306 to move. The sliding plate 306 moves, thereby supporting the box body 1 and adjusting the angle, and adjusting the box body 1 to a horizontal state by adjusting the four sets of leveling mechanisms 3 in turn.

[0027] The lifting mechanism 2 includes two support plates 201, which are welded to the inner wall of the box body 1. The two support plates 201 are rotatably connected with a screw 202 through a bearing. A movable plate 205 is slidably connected to the side wall of the box body 1. The cross plate 206 is welded to the bottom of the movable plate 205. A threaded block 203 is welded in the movable plate 205. The threaded block 203 is threadedly connected to the screw 202. The top of the support plate 201 is connected to a motor 204 through bolts. The output shaft of the motor 204 is connected to the top of the screw 202 through a coupling. The rotation of the motor 204 drives the screw 202 to rotate. The rotation of the screw 202 drives the threaded block 203 to move downward, thereby driving the movable plate 205 to move downward, and then driving the cross plate 206 to move downward.

[0028] The detection mechanism 7 includes an electric push rod 701, which is connected to the bottom of the support plate 201 near the bottom end by bolts. The output shaft of the electric push rod 701 is threadedly connected to the mounting plate 702, and a detection head 703 is installed at the bottom of the mounting plate 702. The electric push rod 701 moves to drive the mounting plate 702 to move downward, thereby driving the detection head 703 to move downward to the concrete surface, and then the detection is carried out. The detection mechanism 5 includes a load plate 501, which is welded to the inner wall of the box body 1, and the top of the load plate 501 is connected to the base 502 by screws, and the top of the base 502 is connected to the damping rod 503 by screws.

The top of the sliding seat 505 is connected to a support plate 506 by screws, and a detector is installed on the top of the support plate 506. When moving, the detector will shake, thereby driving the support plate 506 to move downward, and then driving the sliding seat 505 to move downward. The sliding seat 505 moves downward, thereby compressing the spring 504. At the same time, the spring 504 will generate a rebound force, so that the sliding seat 505 moves upward. Under the action of the damping rod 503, it can absorb part of the energy and reduce vibration. The covering mechanism 6 includes a top plate 601, and the top plate 601 is attached to the top of the box body 1. A threaded hole 602 is opened on the top plate 601, and a fixing bolt 603 is threadedly connected in the threaded hole 602. A sunshade 604 is slidably connected to the top plate 601. By pulling the sunshade 604, sunlight is shielded, which is convenient for observing values.

[0029] Working principle: When in use, the motor 204 rotates to drive the lead screw 202 to rotate, and the lead screw 202 rotates to drive the threaded block 203 to move downward, thereby driving the moving plate 205 to move downward, and then driving the cross plate 206 to move downward. The cross plate 206 moves downward, and the leveling mechanism 3 moves downward, thereby driving the moving wheel to move downward. The box body 1 is supported and lifted by the moving wheel, and the device is moved to the position to be detected by the moving wheel. After moving to the position to be detected, the worm 402 is driven to rotate by rotating the turntable 404, thereby driving the worm wheel 403 to rotate. The worm wheel 403 rotates, and the threaded tube 304 is driven to rotate, thereby driving the threaded rod 305 to rise and fall, and then driving the sliding plate 306 to move. The sliding plate 306 moves, thereby supporting the box body 1 and adjusting the angle, and so on. Adjust the four sets of leveling mechanisms 3 to adjust the box body 1 to a horizontal state, then the electric push rod 701 moves, driving the mounting plate 702 to move downward, thereby driving the detection head 703 to move down to the concrete surface, and then carry out the detection, and then pull the cover plate 604 to block the sunlight for easy observation of the values. After the detection is completed, the electric push rod 701 moves, driving the mounting plate 702 to move upward, thereby driving the detection head 703 to move upward for storage, and then move the device to the next location. During the movement, the detector will shake, thereby driving the support plate 506 to move downward, and then driving the sliding seat 505 to move downward. By moving the sliding seat 505 downward, the spring 504 is compressed, and at the same time the spring 504 will generate a rebound force, causing the sliding seat 505 to move upward, and under the action of the damping rod 503, it can absorb part of the energy and reduce vibration.
