Abstract
Description
Technical Field
[0001] The invention relates to the technical field of material detection equipment, in particular to a building material detection device. Background Art
[0002] Building materials need to have good performance when used. Before use, it is generally necessary to test the performance of building materials. The mechanical properties test of building materials includes compressive strength and flexural strength. The tests of compressive strength and flexural strength are similar, but the difference is that compressive strength is the strength limit when external force is applied. During the test, it is generally the strength of the building material when it is fully supported at the bottom. Flexural strength is the ultimate breaking stress per unit area of the material when it is subjected to bending moment, and it is generally supported only at both ends of the material.
[0003] Existing testing equipment generally needs to complete the compressive strength and flexural strength tests at different workstations. In addition, during the testing process, the material will be damaged after reaching its ultimate strength. The falling of the damaged material will cause damage to the supporting parts. The damaged material will remain at the testing location, affecting the environment of the testing location. It also takes a long time to clean up, which will affect the testing frequency and efficiency. Summary of the invention

[0006] In the present technical scheme, both the compressive strength test and the flexural strength test of the building materials can be carried out at the through groove part, so that two different project tests can be carried out at the same work station, and the functionality of the testing equipment is more comprehensive. Among them, the positioning component is retractable. When it is extended, it can cooperate with the clamping component to support the bottom of the building material.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] One embodiment of the present invention is as follows: Figure 1-8, provides a building material testing equipment, which is mainly used to test the compressive strength and flexural strength of materials, including a box body 1, a workbench 2 is arranged in the box body 1, a through slot 3 is opened on the workbench 2, and clamping parts 4 for clamping building materials are arranged at both ends of the through slot 3. When the building material is tested, it is placed above the through slot 3, wherein the clamping part 4 includes a positioning block 5, and a positioning surface 6 for positioning the building material is formed on the positioning block 5. When the testing work is carried out, the two ends of the building material to be tested are clamped and fixed by the clamping part 4, and the lower end surface of the building material is placed on the positioning surface 6, wherein the positioning surface 6 is lower than the upper end surface of the workbench 2, and the positioning surface 6 here can be designed to be 5-10 cm lower than the upper end surface of the workbench 2 to form a recessed portion to improve the installation stability of the building material, wherein a retractable positioning component 7 is provided in the box body 1 and is located on one side of the through slot 3, and the positioning component 7 has an extended position and a retracted position When the positioning component 7 is in the extended position, one end of the positioning component 7 extends to the other side of the through slot 3. At this time, the positioning component 7 can support the middle position of the lower end of the building material, and a compressive strength test can be performed (the pressurizing position of the pressurizing component can be set at the upper part of the positioning component 7). When the positioning component 7 is in the retracted position, the positioning component 7 is hidden in the lower part of the workbench 2. At this time, only the two ends of the building material are supported and fixed, and the flexural strength test of the building material can be performed. A waste storage part 9 located at the lower part of the through slot 3 is provided in the box body 1. During the detection process, the damaged material can directly fall from the through slot 3 into the waste storage part 9, reducing the time and workload of waste cleaning. In addition, the pressure component 8 in the present invention includes a pressure rod 81, and a pressure sensor for detecting the pressure of the pressure rod 81 is provided on the pressure component 8. The detection signal of the pressure sensor can control the positioning component 7 to move from the extended position to the retracted position. When the material is damaged, the pressure of the pressure rod 81 will suddenly change. At this time, the pressure sensor will send a signal to control the positioning component 7 to retract from the extended position to the retracted position, which can reduce the impact damage to the positioning component 7 caused by the fall of the damaged material.
[0020] In the present embodiment, both the compressive strength test and the flexural strength test of the building materials can be carried out at the through groove 3, so that two different project tests can be carried out at the same work station, and the functionality of the testing equipment is more comprehensive. Among them, the positioning component 7 is retractable. When it is extended, it can cooperate with the clamping component 4 to support the bottom of the building material. At this time, the compressive strength test can be realized. When it is retracted, only the clamping component 4 supports the two ends of the building material. At this time, the flexural strength test can be realized, and the switching between the compressive strength and flexural strength test processes is realized.
[0021] One of the embodiments of the present invention is that the positioning assembly 7 includes a first positioning plate 71, a second positioning plate 72 and a positioning shaft 74, the first positioning plate 71 and the second positioning plate 72 are respectively rotatably connected to the positioning shaft 74, and when the positioning assembly 7 is in the extended position, one end face of the first positioning plate 71 and one end face of the second positioning plate 72 can be rotated to a flush state and be in the same plane as the positioning surface 6. The first positioning plate 71 and the second positioning plate 72 can be rotated to a flush state, which can increase the support area for the building material, and in this embodiment, one end face of the first positioning plate 71 and one end face of the second positioning plate 72 are coplanar with the positioning surface 6, avoiding the situation that there is a gap between the first positioning plate 71 and the second positioning plate 72 and the building material during the detection process, which can better support the building material to be detected, improve the stability of the support and the accuracy of the compressive strength detection.
[0022] Furthermore, a spring 73 is connected between the lower end surface of the first positioning plate 71 and the lower end surface of the second positioning plate 72 of the present invention. When the positioning assembly 7 moves from the telescopic position to the retracted position, the first positioning plate 71 and the second positioning plate 72 are pressed to rotate synchronously and compress the spring 73. During the retraction process, the first positioning plate 71 and the second positioning plate 72 will rotate to form a downward tilt angle. At this time, the waste materials staying on the first positioning plate 71 and the second positioning plate 72 will fall into the waste storage part 9, thereby improving the cleaning efficiency of the waste materials and reducing the damage probability of the positioning assembly 7.
[0023] In order to make the positioning assembly 7 achieve a better supporting effect on the building materials, a supporting component is provided in the box body 1 of the present invention. The supporting component and the positioning assembly 7 are arranged opposite to each other on both sides of the through slot 3. The supporting component includes a first drive motor, a rotating shaft 10 and a bracket 11. The rotating shaft 10 is connected to the output shaft of the first drive motor. The bracket 11 is fixed on the rotating shaft 10. When the positioning assembly 7 is in the extended position, the bracket 11 can rotate to the lower part of the positioning assembly 7 and press the lower end surfaces of the first positioning plate 71 and the second positioning plate 72 to make the upper end surfaces of the first positioning plate 71 and the second positioning plate 72 in a flush state. The bracket 11 can assist the first positioning plate 71 and the second positioning plate 72 in a flush state in the extended position, which can increase the contact area between the positioning assembly 7 and the bottom support of the building materials and improve the stability of the support.
[0024] The lower part of the workbench 2 in the present invention is provided with baffles 12 located on both sides of the through slot 3, and a waste storage part 9 is formed between the baffles 12 and the bottom of the box body 1, wherein a passage 13 for passing the bracket 11 is opened on the baffle 12 located on the same side as the supporting component. During use, since the bracket 11 is a rotating part, it rotates to a horizontal state on one hand to support the lower part of the positioning assembly 7, see the attached Figure 6On the other hand, it rotates to a vertical state to contact the support of the positioning component 7 and away from the through slot 3, wherein the baffle 12 can prevent waste from entering the installation area of the support component, and the design of the channel 13 can prevent the baffle 12 from interfering with the rotation of the bracket 11.
[0025] The box body 1 of the present invention is provided with a second drive motor 14 for driving the positioning assembly 7 to slide, the pressure sensor is in communication connection with the first drive motor, and the first drive motor is in communication connection with the second drive motor 14. In this embodiment, the first drive motor acts as an intermediate component, which first receives the signal from the pressure sensor and then acts on the support component. When the support component releases the support effect on the positioning assembly 7, it sends a signal to control the extension and retraction of the positioning assembly 7 through the second drive motor 14, so as to realize the sequence of the actions of the support component and the positioning assembly 7.
[0026] One embodiment of the present invention is, see attached Figure 1 , 4 , 5. A slide groove 15 is provided at the lower end of the workbench 2, and the positioning component 7 is slidably connected in the slide groove 15. The slide groove 15 includes a first section 1501 and a second section 1502 along the axial direction, the first section 1501 is close to the through groove 3, and the second section 1502 is provided with inclined surfaces 1503 on both side walls of the slide groove 15. When the positioning component 7 slides in the second section 1502, the first positioning plate 71 and the second positioning plate 72 are squeezed by the inclined surfaces 1503 to rotate synchronously. In actual design, a guide groove can be provided on the inclined surface 1503 at one end of the first section 1501 close to the second section 1502, which is more convenient for squeezing the first positioning plate 71 and the second positioning plate 72. The width of the slide groove 15 in the first section 1501 is greater than the sum of the widths of the first positioning plate 71 and the second positioning plate 72. The inclined surface 1503 can be used to apply pressure to the first positioning plate 71 and the second positioning plate 72 to make them tilt, and the inclined surface 1503 can scrape off the waste on the first positioning plate 71 and the second positioning plate 72, thereby cleaning the upper surfaces of the first positioning plate 71 and the second positioning plate 72. When the positioning assembly 7 is in the extended position, one end of the positioning assembly 7 is located in the first section 1501 of the chute 15. The positioning assembly 7 does not completely extend out of the chute 15, so that the positioning assembly 7 is more stable when in the extended position.
[0027] The waste storage part 9 of the present invention is provided with a discharge port 16, so as to facilitate the cleaning of the waste in the waste storage part 9.
[0028] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
