Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a concrete testing device for construction quality acceptance in building engineering. Background Technology

[0002] In construction engineering, the quality acceptance of concrete is a crucial step in ensuring structural safety and durability. To ensure that concrete meets design requirements and achieves standard compressive, tensile, and flexural properties, a series of testing devices are typically used for inspection.

[0003] There are many existing methods for concrete testing, including compressive strength testing. During compressive strength testing, crushed concrete usually falls onto the test platform, requiring manual cleaning by staff to ensure the platform is flat for the next test. In addition, existing concrete testing equipment is large and inconvenient to carry to different construction environments for acceptance testing, causing inconvenience in use. Utility Model Content

[0004] The purpose of this invention is to provide a concrete testing device for construction quality acceptance in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete testing device for construction quality acceptance, comprising a testing box, and further comprising:

[0006] The test chamber has fixed housings on both sides. A partition is fixedly connected to the bottom of the test chamber's inner cavity. A push plate is hinged to the front side of the top of the partition. A hydraulic rod is fixedly connected to the top of the test chamber. A pressure plate is fixedly connected to the bottom of the hydraulic rod. A controller for use with the hydraulic rod is fixedly connected to one side of the test chamber. A drive assembly for positioning concrete is fixedly connected to one side of the fixed housing. The drive assembly includes a DC motor. A monitoring camera is fixedly connected to one side inside the test chamber.

[0007] Preferably, a counterweight is fixedly connected to the rear side of the top of the push plate, and handles are fixedly connected to both sides of the top of the detection box.

[0008] Preferably, a reinforcing block is fixedly connected to the top of the fixed shell, and one side of the reinforcing block is fixedly connected to the testing box.

[0009] Preferably, the output end of the DC motor extends through the interior of the fixed housing and the detection box and is fixedly connected to a bidirectional lead screw. Both sides of the surface of the bidirectional lead screw are fitted with internal thread plates. A sliding block is fixedly connected to one side of the internal thread plate. A sliding rod is slidably connected inside the sliding block. Both ends of the sliding rod are fixedly connected to the inner wall of the fixed housing. A push rod is fixedly connected to one side of the internal thread plate. A clamping plate is fixedly connected to one side of the push rod.

[0010] Preferably, a rubber pad is fixedly connected to one side of the card plate, and the rubber pad is arranged in an array.

[0011] Preferably, the top rear side of the push plate is hinged to two connecting frames, the connecting frames are slidably connected to a limit rod, and the limit rod is movably connected to an extension rod.

[0012] Preferably, a retaining frame is fitted onto the surface of the extension rod, and one side of the retaining frame is fixedly connected to the pressure plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention first lowers the pressure plate as the hydraulic rod descends. At this time, the extension rod inside the retaining frame is not pulled, causing the limiting rod to raise the connecting frame. As the hydraulic rod descends, the controller can control the downward pressure of the hydraulic rod, and the monitoring camera records the detection process. After the pressure resistance is completed, the hydraulic rod drives the pressure plate to rise to a certain height. The retaining frame then drives the extension rod in conjunction with the limiting rod to raise the connecting frame. Simultaneously, the push plate is hinged on one side of the partition, thereby causing the push plate to pour out the concrete slag at the top, eliminating the need for manual cleaning and improving ease of use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 As shown, a concrete testing device for construction quality acceptance includes a testing box 1 and a fixed shell 2 fixed to both sides of the testing box 1. A partition 3 is fixedly connected to the bottom of the inner cavity of the testing box 1, which facilitates the support of a push plate 4. The push plate 4 is hinged to the front side of the top of the partition 3, which facilitates the drainage of debris out of the testing box 1. A hydraulic rod 5 is fixedly connected to the top of the testing box 1, and a pressure plate 51 is fixedly connected to the bottom of the hydraulic rod 5. A controller 6 for use with the hydraulic rod 5 is fixedly connected to one side of the testing box 1. The controller 6 is electrically connected to the hydraulic rod 5 and simultaneously electrically connected to the DC motor 701 in the drive assembly 7, which facilitates the driving and control of the hydraulic rod 5 and the DC motor 701. A drive assembly 7 for positioning concrete is fixedly connected to one side of the fixed shell 2. The drive assembly 7 includes a DC motor 701. A monitoring camera 8 is fixedly connected to one side of the inside of the testing box 1, which facilitates the recording of the concrete condition during crushing.

[0022] A counterweight 9 is fixedly connected to the rear side of the top of the push plate 4. The counterweight 9 facilitates the reset of the push plate 4. Handles 10 are fixedly connected to both sides of the top of the detection box 1. A reinforcing block 11 is fixedly connected to the top of the fixed shell 2. By fixing the reinforcing block 11 to the detection box 1, the connection strength between the fixed shell 2 and the detection box 1 can be improved. One side of the reinforcing block 11 is fixedly connected to the detection box 1.

[0023] The output end of the DC motor 701 extends through the interior of the fixed housing 2 and the detection box 1 and is fixedly connected to a bidirectional lead screw 702. Both sides of the surface of the bidirectional lead screw 702 are fitted with internal thread plates 703. A sliding block 704 is fixedly connected to one side of the internal thread plate 703. A sliding rod 705 is slidably connected inside the sliding block 704. Both ends of the sliding rod 705 are fixedly connected to the inner wall of the fixed housing 2. Turning on the DC motor 701 allows the bidirectional lead screw 702 to rotate. When the bidirectional lead screw 702 rotates, the two internal thread plates 703... 03 will drive the push rod 706 to move relative to each other, and when the internal thread plate 703 moves, it will drive the sliding block 704 to move in a limited position on the surface of the sliding rod 705. However, as the clamping plate 707 moves, it will drive the rubber pad 708 to press against the concrete block, thereby preventing the concrete from moving during the concrete compressive strength test. The push rod 706 is fixedly connected to one side of the internal thread plate 703, the clamping plate 707 is fixedly connected to one side of the push rod 706, and the rubber pad 708 is fixedly connected to one side of the clamping plate 707. The rubber pads 708 are arranged in an array.

[0024] Connecting frames 12 are hinged to both sides of the top rear side of the push plate 4. A limiting rod 13 is slidably connected inside the connecting frame 12. An extension rod 14 is movably connected inside the limiting rod 13. A retaining frame 15 is fitted on the surface of the extension rod 14. When the hydraulic rod 5 drives the pressure plate 51 to rise to a certain height, the retaining frame 15 will drive the extension rod 14 to cooperate with the limiting rod 13 to raise the connecting frame 12. At the same time, the push plate 4 is hinged on one side of the partition plate 3, thereby linking the push plate 4 to pour out the concrete slag at the top. One side of the retaining frame 15 is fixedly connected to the pressure plate 51.

[0025] Working principle: First, the concrete block to be tested is placed on top of the push plate 4. Then, by turning on the DC motor 701, the bidirectional lead screw 702 rotates. When the bidirectional lead screw 702 rotates, the two internal thread plates 703 drive the push rod 706 to move relative to each other. When the internal thread plates 703 move, they drive the sliding block 704 to move in a limited position on the surface of the sliding rod 705. As the clamping plate 707 moves, it drives the rubber pad 708 to press against the concrete block. Then, the hydraulic rod 5 drives the pressure plate 51 to descend and squeeze the concrete, and the monitoring camera works in conjunction with this. The first 8 records the testing process. However, when the pressure plate 51 descends, the extension rod 14 inside the retaining frame 15 will not be pulled to make the limiting rod 13 drive the connecting frame 12 to rise. After the pressure test is completed, the clamping plate 707 is reset to the inside of the fixed shell 2. At this time, as the hydraulic rod 5 drives the pressure plate 51, when it rises to a certain height, the retaining frame 15 will drive the extension rod 14 to cooperate with the limiting rod 13 to make the connecting frame 12 rise. At the same time, the push plate 4 is hinged on one side of the partition 3, thereby linking the push plate 4 to pour out the concrete slag at the top.
