Description

Technical Field

[0001] The utility model relates to the technical field of hardness detection devices, in particular to a hardness detection device for municipal engineering building materials. Background Art

[0002] Commonly used building materials in municipal engineering include concrete, bricks, etc. Their hardness has an important impact on the quality and durability of the project. Traditional municipal engineering building material hardness testing usually uses equipment such as Rockwell hardness tester to measure the hardness value of the material by applying a certain pressure on the surface of the material. However, this traditional method has some defects:

[0003] Lack of protective measures: When using traditional hardness testing equipment, due to the lack of effective protective measures, building materials are often easily crushed, resulting in flying fragments and posing a safety hazard.

[0004] Single-point testing: Traditional hardness testing devices can usually only test a single point on a building material. After a piece of material has been tested, its structure will undergo stress changes and therefore it cannot be reused. In actual engineering, it is necessary to take the average value multiple times to obtain accurate hardness data, which requires testing of multiple materials, resulting in a waste of materials and time.

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] Combined with Figure 1 To Attachment Figure 7A municipal engineering building material hardness testing device comprises a base plate 1, leveling feet 18 are fixedly provided at the four corners of the bottom of the base plate 1, a bubble level 19 is fixedly provided on the front and side of the base plate 1, an L-shaped bracket 2 is fixedly provided on the rear side of the upper end surface of the base plate 1, an electric push rod 3 is fixedly provided on the upper end of the L-shaped bracket 2, the piston end of the electric push rod 3 extends into the L-shaped bracket 2 and is fixedly provided with a testing plate 4, a supporting platform 5 is fixedly provided at the center of the upper end surface of the base plate 1, a clamp assembly for fixing building materials is fixedly provided on the upper end surface of the supporting platform 5, two groups of hardness testing balls 6 are movably provided on the lower end surface of the testing plate 4, a pressure sensor 7 is provided at the movable connection between the hardness testing balls 6 and the testing plate 4, side enclosures 8 are fixedly provided on the left and right sides of the L-shaped bracket 2, and a front enclosure with adjustable height is fixedly provided on the front side of the upper end surface of the base plate 1.

[0028] In this embodiment, the height-adjustable front baffle includes a plug-in housing 9 fixedly arranged on the upper end surface of the bottom plate 1, a lifting baffle 10 is inserted inside the plug-in housing 9, and a limiting mechanism is matched between the lifting baffle 10 and the plug-in housing 9. The limiting mechanism includes a fixing bolt 11 threadedly connected to the front of the plug-in housing 9, and also includes a threaded hole 12 arranged on the side of the lifting baffle 10, and the fixing bolt 11 is threadedly connected to the threaded hole 12. The lifting baffle 10 is made of transparent acrylic material.

[0029] In this embodiment, the clamp assembly includes a fixing plate 13 fixed to the left and right sides of the upper end surface of the supporting platform 5, and an adjusting bolt 14 is threadedly connected to the fixing plate 13. A fixed pressure plate 15 is rotatably provided at the lower end of the adjusting bolt 14.

[0030] In this embodiment, T-shaped sockets 16 are provided on both sides of the bottom surface of the detection plate 4, and the two hardness detection balls 6 are movably inserted into the T-shaped sockets 16 through T-shaped rods 17. The pressure sensor 7 is fixedly arranged on the top surface of the T-shaped sockets 16.

[0031] Before using the utility model, first connect the external power supply. The specific working principle of the utility model is as follows:

[0032] 1. Preparation:

[0033] Place the building materials that need hardness testing on the support platform 5, ensure that the base plate 1 is stable and flat, and the bubble level 19 shows a horizontal state, then use the clamp assembly to compact and fix the building materials, adjust the height of the front enclosure so that its upper edge is higher than the upper surface of the building materials to be tested to prevent debris from splashing.

[0034] 2. Conduct testing:

[0035] Start the electric push rod 3 so that the hardness test ball 6 at the lower end of the test plate 4 is applied to the surface of the building material. At the same time, the pressure sensor 7 monitors the pressure change in real time. The indentation diameter of the two hardness test balls 6 on the surface of the building material is controlled by controlling the stroke of the electric push rod. The stroke is the same, so the indentation diameter is the same.

[0036] When the hardness detection ball 6 at the lower end of the detection plate 4 applies pressure, the pressure sensor 7 will sense the pressure change and convert it into an electrical signal and transmit it to the control system. The control system can be an external pressure display or a computer for recording the pressure value. The indentation diameter is the same, and the hardness can be calculated by averaging the pressure values.

[0037] The bottom leveling feet and bubble level ensure the stability and levelness of the device. At the same time, the design of the side and front enclosures can effectively prevent the construction materials from being crushed and splashed, protecting the safety of operators.

[0038] By arranging two sets of hardness test balls and T-shaped sockets at the lower end of the test plate, the device can perform hardness tests on multiple points at the same time, improving the test efficiency and accuracy. The pressure applied by each hardness test ball can be monitored in real time by a pressure sensor to obtain accurate hardness data.

[0039] The lifting baffle made of transparent acrylic material enables the operator to clearly observe the detection process, ensuring the accuracy and reliability of the detection.

[0040] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
