Description

Technical Field

[0001] This utility model relates to the field of concrete hardness testing technology, specifically a concrete hardness testing device. Background Technology

[0002] Concrete is an artificial stone material made by mixing cement as the main binder with water, sand, and gravel, and, when necessary, chemical admixtures and mineral admixtures, in appropriate proportions, and then uniformly mixing, compacting, molding, and curing. Concrete is widely used in my country's construction industry. To ensure the quality of concrete production, samples need to be taken after the concrete production is completed, and hardness testing devices are used to test its hardness.

[0003] For example, Chinese patent application CN202220151909.7 discloses a concrete hardness testing device, which includes a base plate and a frame plate arranged in an inverted "U" shape. The frame plate is mounted on top of the base plate, and its two ends are fixedly connected to the top sides of the base plate. A hydraulic cylinder is fixedly mounted in the middle of the top of the frame plate, and a telescopic rod is installed inside the hydraulic cylinder. The bottom end of the telescopic rod moves through the middle of the top of the frame plate and extends into the interior of the frame plate. This invention allows the corresponding threaded rod to rotate by rotating two cranks, enabling it to move horizontally. This allows the two clamping plates to move closer or further apart, thus clamping samples of different sizes, facilitating testing, and improving testing efficiency.

[0004] However, in actual use, when concrete blocks are removed and tested using the aforementioned device, the concrete blocks with lower hardness break during the testing process, requiring manual removal by staff. Furthermore, if the debris is not cleaned up in time, it can easily affect the accuracy of subsequent concrete hardness testing, resulting in poor performance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete hardness testing device. By driving a pusher plate to move horizontally along the inside of a U-shaped testing frame, it cleans up the waste material left behind during testing, thus replacing the tedious and dangerous manual cleaning. This achieves one-click material cleaning, improves waste cleaning efficiency, reduces the workload of workers, and ensures the efficiency of retesting concrete blocks, effectively solving the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a concrete hardness testing device, including a testing body, wherein a control cabinet is fixedly installed on one side of the testing body;

[0007] The bottom of the testing machine is equipped with a material pushing component for centralized cleaning of waste material after the hardness test is completed.

[0008] The top of the inside of the testing machine is equipped with a testing component for comprehensive hardness testing of the top of the concrete block;

Slots are provided on both sides of the detection machine body. One end of the connecting rod passes through one of the slots and is fixedly connected to the center of one side of the pushing plate, so that the connecting rod can move to drive the pushing plate to move.

[0010] Preferably, the control cabinet has a slot at the center of the bottom of the drive slot, and the two inner walls of the slot are connected by a bearing to the same threaded rod. A threaded block is threadedly connected to the threaded rod, and the top of the threaded block is fixedly connected to the bottom of the other end of the connecting rod, so as to facilitate the rotation of the threaded rod to drive the threaded block to move, thereby moving the connecting rod.

[0011] Preferably, the bottom of the detection body has two horizontally distributed sliding grooves, and the sliding grooves are located at the bottom of the grooves. The bottom of the U-shaped detection frame is fixedly provided with two horizontally distributed fixed frames. The fixed frames are slidably disposed inside the sliding grooves. The bottom of the fixed frames is provided with a number of evenly distributed ball bearings, which facilitates the cooperation between the sliding grooves and the fixed frames, making the movement of the U-shaped detection frame more stable, avoiding deviation, reducing friction, extending service life, and making operation smoother.

[0012] Preferably, the bottom of the detection body has two horizontally distributed sliding grooves, and the sliding grooves are located at the bottom of the grooves. The bottom of the U-shaped detection frame is fixedly provided with two horizontally distributed fixed frames, which are slidably disposed inside the sliding grooves. The bottom of the fixed frames is provided with a number of evenly distributed ball bearings.

[0013] Preferably, the detection component includes a drive block located at the top of the inside of the detection machine body. An electric telescopic rod is fixedly installed on the top of one side of the inside of the detection machine body. One end of the electric telescopic rod is fixedly connected to the front end of one side of the drive block. A slide rail is slidably installed on the rear side of the inside of the drive block. The two ends of the slide rail are fixedly connected to the two side walls of the top of the inside of the detection machine body, respectively, so as to facilitate the horizontal movement of the drive block along the slide rail.

[0014] Preferably, an electric push rod is fixedly provided at the bottom center of the drive block, and a fixing plate is fixedly provided at the bottom end of the piston rod of the electric push rod.

[0016] Compared with the prior art, this utility model provides a concrete hardness testing device, which has the following beneficial effects:

[0017] 1. This utility model uses a drive connecting rod to push a pusher plate horizontally within a U-shaped testing frame, thereby pushing the waste material at the top of the U-shaped testing frame into the guide frame inlet. Once the waste material is pushed into the guide frame, the motor automatically reverses, driving the threaded block to move outward. Then, the drive connecting rod pulls the pusher plate back to its initial position, restoring the device to a ready state, allowing new concrete test blocks to be placed in for testing again. This replaces the tedious and dangerous manual cleaning, achieving one-click cleaning, improving waste cleaning efficiency, reducing the workload of workers, and ensuring the efficiency of retesting concrete blocks.

[0018] 2. This utility model uses an electric telescopic rod to drive the entire detection module to move along the slide rail, and then uses an electric push rod to drive multiple detection heads to press down synchronously. Pressure sensors collect pressure data in real time to detect the hardness of the concrete block. After the detection at one point is completed, the electric telescopic rod drives the detection module to move to the next detection area. Similarly, other points on the top of the concrete block are detected, thereby realizing automated, multi-point, and full-coverage hardness detection of concrete test blocks, which greatly improves detection efficiency, data comprehensiveness, and result accuracy, while eliminating the random errors of single-point detection and human operation interference.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, this utility model provides a concrete hardness testing device, including a testing body 1. A control cabinet 2 is fixedly installed on one side of the testing body 1. A guide frame 6 is fixedly installed on the side of the testing body 1 near another slot 5 to facilitate the discharge of waste materials and keep the working environment clean. A drive slot 7 is opened inside the control cabinet 2, and a slot is opened at the center of the bottom of the drive slot 7 in the control cabinet 2.

[0028] like Figure 1-4 As shown, the bottom of the testing machine body 1 is provided with a pusher assembly 3 for collecting and cleaning up waste material after hardness testing. The pusher assembly 3 includes a U-shaped testing frame 31, which is located at the bottom of the testing machine body 1. A pusher plate 36 is provided on one side of the top of the U-shaped testing frame 31. A connecting rod 35 is provided inside the drive groove 7. Slots 5 are provided on both sides of the testing machine body 1. One end of the connecting rod 35 passes through one of the slots 5 and is fixedly connected to the center of one side of the pusher plate 36, so that the connecting rod 35 can move and drive the pusher plate 36 to move. The same threaded rod 37 is connected between the two sides of the slot through a bearing. A threaded block 38 is threadedly connected to the threaded rod 37. The top of the threaded block 38 is fixedly connected to the bottom of the other end of the connecting rod 35, so that the threaded rod 37 can rotate and drive the threaded block 38 to move, thereby moving the connecting rod 35.

[0029] The bottom of the inner part of the detection body 1 has two horizontally distributed sliding grooves 34, which are located at the bottom of the slot 5. The bottom of the U-shaped detection frame 31 is fixed with two horizontally distributed fixed frames 32, which are slidably disposed inside the sliding grooves 34. The bottom of the fixed frames 32 is rotatably provided with several evenly distributed ball bearings 33, which facilitates the cooperation between the sliding grooves 34 and the fixed frames 32, making the movement of the U-shaped detection frame 31 more stable, avoiding deviation, reducing friction, extending service life, and making operation smoother. The control panel in the control cabinet 2 is used to control the motor 39 to work.

[0030] After the sampled concrete block hardness test is completed by setting up the pusher assembly 3, the operator starts the pusher assembly 2 through the control panel on the control box 2, so that the motor 39 drives forward, drives the threaded rod 37 to rotate, drives the threaded block 38 to move horizontally inward along the threaded rod 37, and drives the connecting rod 35 to push the pusher plate 36 horizontally within the U-shaped test frame 31, thereby pushing the waste at the top of the U-shaped test frame 31 into the inlet of the guide frame 6. The waste is pushed into the guide frame 6 and falls into the collection container prepared by the staff below. After the pusher is in place, the motor 39 automatically reverses, drives the threaded block 38 to move outward, and then drives the connecting rod 35 to drag the pusher plate 36 back to the initial position. The device returns to the ready state, and new concrete test blocks can be put in for testing again. This replaces the tedious and dangerous manual cleaning, realizes one-click cleaning, improves waste cleaning efficiency, reduces the labor intensity of the staff, and ensures the efficiency of retesting concrete blocks.

[0031] like Figure 1-3 As shown in Figure 5, the top of the inside of the testing machine body 1 is provided with a testing component 4 for performing a comprehensive hardness test on the top of the concrete block. The testing component 4 includes a driving block 41, which is located at the top of the inside of the testing machine body 1. An electric telescopic rod 42 is fixedly provided on the top of one side of the inside of the testing machine body 1. One end of the electric telescopic rod 42 is fixedly connected to the front end of one side of the driving block 41. A slide rail 47 is slidably provided on the rear side of the inside of the driving block 41. Both ends of the slide rail 47 are fixedly connected to the two side walls of the top of the inside of the testing machine body 1, respectively, so as to facilitate the horizontal movement of the driving block 41 along the slide rail 47.

[0032] An electric push rod 43 is fixedly installed at the bottom center of the drive block 41. A fixing plate 44 is fixedly installed at the bottom end of the piston rod of the electric push rod 43. Several detection heads 45 are evenly distributed front and back at the bottom of the fixing plate 44. The detection heads 45 are located at the top of the U-shaped detection frame 31. A pressure sensor 46 is fixedly installed on the detection head 45. This allows multiple evenly distributed detection heads 45 to detect multiple points at the same time, improving efficiency. At the same time, the pressure sensor 46 provides real-time data feedback, improving detection accuracy and reliability.

[0033] By setting up the detection component 2, the concrete block requiring hardness testing is placed inside the U-shaped detection frame 31. Then, the control panel drives the electric telescopic rod 42 to move the entire detection module along the slide rail 47, positioning the detection head 45 at the first test area above the test block. The electric push rod 43 is activated, pushing multiple detection heads 45 downwards synchronously. The pressure sensor 46 collects pressure data in real time until the test block is crushed. The control cabinet 2 records the peak pressure data at each detection point. After the test at that point is completed, the electric push rod 43 retracts, raising the detection head 45. Then, the electric telescopic rod 42 moves the detection module to the next test area. Similarly, other points on the top of the concrete block are tested until all predetermined points are tested. After the test is completed, the control system sends a signal to activate the material pushing component 3 to clean up the waste material, preparing for the next test. This achieves automated, multi-point, and full-coverage hardness testing of concrete test blocks, greatly improving testing efficiency, data comprehensiveness, and result accuracy, while eliminating the random errors of single-point testing and human interference.
