Description

Technical Field

[0001] The utility model belongs to the technical field of building material detection, and specifically relates to a new building material hardness detection device. Background Art

[0002] In some specific cases, it is necessary to test the hardness of the front and back sides of building materials. These cases may include: 1. Material surface treatment: If the front and back sides of the building materials have undergone different surface treatments (such as coating, plating, etc.), these treatments may affect the hardness of the material surface. In this case, hardness testing of the front and back sides can help evaluate the effect and uniformity of the surface treatment. 2. Material non-uniformity: Some building materials may have non-uniformity during the production process, resulting in different hardness in different parts of the material (including the front and back). In this case, hardness testing of the front and back sides can help identify material non-uniformity and evaluate its impact on overall performance. 3. Specific application requirements: In some specific building applications, hardness testing of the front and back sides of building materials may be required to meet specific engineering requirements or standards. For example, some structural parts may need to have a higher hardness on their front side to resist external impact or wear, while the back side may need a lower hardness to provide better shock absorption performance.

[0003] When the existing building material hardness testing device needs to test the hardness of the front and back sides of the comparison sample, the sample to be tested needs to be manually turned over, and the sample to be tested cannot be automatically turned over quickly and stably, resulting in low testing efficiency. Utility Model Content

[0005] To achieve the above objectives, the utility model adopts the following technical solution: a new type of building material hardness detection device, comprising a frame, a controller is installed on the side of the frame, a turning table assembly is rotatably installed on the frame, a support frame is installed on the frame above the turning table assembly, a detection mechanism is installed on the bottom surface of the support frame, the turning table assembly comprises a connecting frame, both sides of the connecting frame are connected with connecting shafts, the connecting shaft is rotatably installed on the frame, one end of the connecting shaft is connected to the output shaft of the driving motor, the upper and lower sides of the connecting frame are respectively rotatably connected with an upper support plate and a lower support plate by hinges, the sides of the upper support plate and the lower support plate are rotatably connected to one end of a hydraulic cylinder by a pin shaft, the other end of the hydraulic cylinder is rotatably connected to a fixed seat by a pin shaft, and the fixed seat is installed on the connecting frame.

[0006] The beneficial effects of the utility model are as follows: the driving motor can drive the building materials placed inside the connecting frame to flip over on the front and back sides, and by controlling the extension and retraction of the hydraulic cylinder, the upper support plate and the lower support plate can provide stable support for the building materials, or the detection mechanism can be smoothly moved downward to perform hardness detection.

[0008] As a further improvement of the above technical solution: when the hydraulic cylinder is retracted to the end of the stroke, the angle between the upper support plate, the lower support plate and the connecting frame is 90 degrees.

[0009] The beneficial effect of this improvement is that after the hydraulic cylinder contracts and drives the upper support plate or the lower support plate to open, the operator can conveniently place the building materials to be tested into the inner side of the connection frame from top to bottom.

[0010] In order to effectively withstand the pressure applied by the testing agency during the testing process;

[0011] As a further improvement of the above technical solution: the connecting frame is a square frame structure, the straight line where the axis of the detection mechanism is located passes vertically through the straight line where the axis of the connecting shaft is located, and the straight line where the axis of the detection mechanism is located passes vertically through the center point of the connecting frame.

[0012] The beneficial effect of this improvement is that the force applied by the detection mechanism when it is pressed down can be stably and evenly borne by the flip table assembly, thereby ensuring the stability of the flip table assembly during the detection process.

[0013] In order to ensure the stability of the hydraulic cylinder installation;

[0014] As a further improvement of the above technical solution: the fixing seat is an angle iron structure.

[0015] The beneficial effect of this improvement is that the fixing seat can stably connect the connection frame and the hydraulic cylinder, thereby ensuring stable use of the hydraulic cylinder.

[0016] In order to make the upper and lower end surfaces of the building materials perpendicular to the axis of the detection mechanism during the detection process to ensure the accuracy of the detection;

[0017] As a further improvement of the above technical solution: an inclination sensor is installed on the fixed seat, and the installation plane of the inclination sensor is perpendicular to the upper and lower end surfaces of the upper support plate and the lower support plate when the hydraulic cylinder is retracted to the end of the stroke, and the inclination sensor and the drive motor are electrically connected to the PLC module in the controller.

[0018] The beneficial effect of this improvement is that under the control of the PLC module, the driving motor drives the building materials inside the connection frame to rotate to an angle where the upper and lower end surfaces are perpendicular to the axis of the detection mechanism, thereby ensuring the accuracy of the detection.

[0019] In order to ensure the stability of the installation of the detection mechanism;

[0020] As a further improvement of the above technical solution: the support frame includes a cross bar, an inclined bar and a top plate, the hydraulic cylinder in the detection mechanism is installed on the top plate, the top plate and one end of the cross bar are connected to the frame, and the top plate is installed on the top surface of the cross bar.

[0021] The beneficial effect of this improvement is that the cross bar can increase the supporting strength of the top plate, so that the top plate provides stable installation support for the detection mechanism.

[0022] In order to ensure the supporting strength of the crossbar;

[0023] As a further improvement of the above technical solution: the two ends of the oblique rod are respectively connected to the side surface of the frame and the front side of the bottom surface of the cross bar.

[0024] The beneficial effect of this improvement is that a structurally stable triangular support structure is formed between the cross bar, the diagonal bar and the frame, thereby ensuring the support strength provided by the cross bar to the top plate.

The driving motor 33 can drive the building materials placed on the inner side of the connecting frame 31 to flip over the front and back sides. By controlling the extension and retraction of the hydraulic cylinder 35, the upper support plate 34 and the lower support plate 39 provide stable support for the building materials, or the detection mechanism 5 moves down smoothly for hardness detection. When the hydraulic cylinder 35 is retracted to the end of the stroke, the angle between the upper support plate 34, the lower support plate 39 and the connecting frame 31 is 90 degrees. After the hydraulic cylinder 35 is retracted to drive the upper support plate 34 or the lower support plate 39 to open, the operator can conveniently put the building materials to be tested into the inner side of the connecting frame 31 from top to bottom. The connecting frame 31 is a square frame structure, the straight line where the axis of the detection mechanism 5 is located passes perpendicularly through the straight line where the axis of the connecting shaft 32 is located, and the straight line where the axis of the detection mechanism 5 is located passes perpendicularly through the center point of the connecting frame 31, and the force applied by the detection mechanism 5 when it is pressed down can be stably and evenly borne by the flip table assembly 3, ensuring the stability of the flip table assembly 3 during the detection process, the fixed seat 36 is an angle iron structure, the fixed seat 36 can stably connect the connecting frame 31 and the hydraulic cylinder 35, ensuring the stable use of the hydraulic cylinder 35, and an inclination sensor 37 is installed on the fixed seat 36, and the installation plane of the inclination sensor 37 is perpendicular to the upper and lower end surfaces of the upper support plate 34 and the lower support plate 39 when the hydraulic cylinder 35 is retracted to the end of the stroke. The inclination sensor 37 and the drive motor 33 are electrically connected to the PLC module in the controller 2. Under the control of the PLC module, the drive motor 33 drives the building materials inside the connection frame 31 to rotate to an angle where the upper and lower end surfaces are perpendicular to the axis of the detection mechanism 5, thereby ensuring the accuracy of the detection. The support frame 4 includes a cross bar 41, an inclined bar 42 and a top plate 43. The hydraulic cylinder in the detection mechanism 5 is installed on the top plate 43.

The top surface of the material is tested for hardness; subsequently, the testing mechanism 5 is reset under the control of the controller 2, and the hydraulic cylinder 35 connected to the upper support plate 34 is retracted to the minimum stroke, driving the upper support plate 34 to be covered on the upper side of the connecting frame 31 and parallel to the lower support plate 39, and then the output shaft of the driving motor 33 drives the connecting frame 31 to rotate 180 degrees through the connecting shaft 32, so that the bottom surface of the building material faces upward, and then the hydraulic cylinder 35 connected to the lower support plate 39 is retracted to the minimum stroke, driving the lower support plate 39 to open, and then the testing mechanism 5 moves down again to perform a hardness test on the back side of the building material.
