Description

Technical Field

[0001] The invention belongs to the technical field of building material detection, and specifically refers to a building material detection device. Background Art

[0002] With the continuous development of the construction industry and people's concern about building quality and safety, building material testing has become a vital link. Testing of building materials can avoid adverse consequences such as construction accidents or shortening the service life of buildings due to strength failure of some building materials. Building material testing equipment is used to evaluate and test the quality, performance, safety and other aspects of building materials, and is an important building material testing tool.

[0003] When testing the strength of building materials, the building material testing devices in the prior art mainly measure the maximum pressure when the building materials are damaged by squeezing them, thereby obtaining the maximum pressure load that the building materials can withstand. However, during the use of buildings, building materials are not only subjected to pressure, but also to tension, torsion or shear force. The existing building material testing devices lack the function of simultaneously testing the pressure, tension, torsion and shear force of building materials, and cannot meet the needs of testing building materials of different shapes and specifications. The scope of application is narrow, which affects the detection efficiency.

[0020] (2) The material support plate can provide a placement area for the building materials to be tested, and the lifting motor drives the lifting screw to rotate, so that the lifting slide plate is lifted, and the building materials to be tested are lifted to a position where they can be clamped and fixed by the material testing component, thereby reducing the number of manual loading operations;

[0021] (3) The hydraulic push-pull rod can drive the material detection components to slide toward or away from each other. The building materials fixed on the material detection components will generate pressure or tension. The pressure and tension of the building materials are recorded by the tension and compression sensors, thus achieving the technical effect of detecting the pressure and tension loads of the building materials.

[0022] (4) The rotating drive motor drives the rotating drive gear to rotate, and the rotating drive gear drives the rotating ring to rotate.

[0024] (6) The 3D scanning component can slide left and right on the top of the frame by driving the translation screw to rotate through the screw motor, and the building materials placed on the material support plate below can be 3D scanned by the 3D camera to automatically obtain the shape and size data information of the building materials.

[0025] (7) The adaptive adjustment of the clamping range by the material fixing component and the application of force in multiple directions to the clamped building materials effectively solves the technical problems that the building material detection device in the prior art cannot adapt to building materials of different shapes and specifications and cannot simultaneously meet the requirements of detecting the pressure, tension, torsion and shear force of building materials.

The 3D camera 52 is slidably arranged above the detection slide rod 111. A control screen 61 is provided above the main controller 6.

[0049] like Figure 1-Figure 11As shown, the screw motor 121, the rotation drive motor 2123, the transverse motor 234, the longitudinal motor 235, the hydraulic push-pull rod 3, the tension and compression sensor 321, the torque sensor 322, the lifting motor 411, the lifting hydraulic rod 46, the 3D camera 52, the control screen 61 and the shear sensor are electrically connected to the main controller 6 respectively.

[0050] The specific implementation of this embodiment is as follows: before the device is used, the symmetrical material detection components 2 are respectively located at the left and right ends of the detection sliding rod 111, and the user places the building materials to be detected (such as concrete, steel bars, stone, wood, etc.) on the material support plate 45, and makes the axial direction of the building materials parallel to the moving direction of the material detection component 2, and starts the lifting motor 411 through the control panel 61. The lifting motor 411 drives the lifting screw rod 42 to rotate, and the lifting screw rod 42 is engaged with the lifting slide plate 44. Therefore, the rotation of the lifting screw rod 42 can drive the lifting slide plate 44 to lift, so that the material support plate 45 drives the building materials to lift, and the building materials are lifted to the central axis position of the symmetrical material detection component 2, which is convenient for the material detection component 2 to clamp and fix the building materials to be tested.

[0051] After the building materials are lifted, the 3D scanning component 5 will start automatically, the screw motor 121 will start to drive the translation screw 12 to rotate, thereby driving the scanning frame 51 to slide left and right, and the 3D camera 52 will start synchronously to perform 3D scanning on the building materials placed on the material support plate 45 below, thereby automatically obtaining the shape and size data information of the building materials. The main controller 6 adjusts the material detection component 2 according to the building material size data obtained by the 3D camera 52, and first automatically starts the hydraulic push-pull rod 3, the telescopic rod of the hydraulic push-pull rod 3 extends and pushes the symmetrical material detection components 2 to approach each other. , and the horizontal motor 234 and the longitudinal motor 235 are automatically started at the same time, so that the horizontal positive and negative screw rods 2311 and the longitudinal positive and negative screw rods 2313 rotate respectively. When the horizontal positive and negative screw rods 2311 rotate, the upper ends of the longitudinal clamping plates 232 are respectively engaged with the positive and negative threads of the horizontal positive and negative screw rods 2311, so the longitudinal clamping plates 232 will be displaced toward or away from each other, thereby changing the distance between the longitudinal clamping plates 232. Similarly, the rotation of the longitudinal positive and negative screw rods 2313 will drive the symmetrical horizontal clamping plates 233 to be displaced toward or away from each other, thereby changing the distance between the horizontal clamping plates 233. The main control The controller 6 adjusts the telescopic amount of the telescopic rod of the hydraulic push-pull rod 3, the distance between the longitudinal clamping plates 232 and the distance between the transverse clamping plates 233 according to the 3D size information of the building material, so as to adapt to the shape and size of the building material. When the hydraulic push-pull rod 3 pushes the material detection assembly 2 to slide toward each other, the two ends of the building material will enter the area enclosed by the transverse clamping plates 233 and the longitudinal clamping plates 232. When the transverse clamping plates 233 and the longitudinal clamping plates 232 completely enclose the two ends of the building material, the hydraulic push-pull rod 3 stops pushing, and the transverse motor 234 and the longitudinal motor 235 rotate synchronously, so that the two ends of the building material are completely enclosed. The longitudinal clamping plate 232 and the transverse clamping plate 233 are respectively slid toward each other until the longitudinal clamping plate 232 and the transverse clamping plate 233 respectively clamp the two ends of the building material. If the cross-section of the building material is a circular surface or an arc surface, the longitudinal anti-skid rubber 2321 and the transverse anti-skid rubber 2331 will generate friction on the ends of the building material to prevent the building material from slipping between the longitudinal clamping plate 232 and the transverse clamping plate 233 during the twisting process and losing the fixing effect of the longitudinal clamping plate 232 and the transverse clamping plate 233. At this time, the building material has been fixed between the symmetrical material detection components 2, waiting for the next detection process.

[0052] When the pressure load of the building material needs to be tested, the hydraulic push-pull rod 3 will continue to push the material detection assembly 2 to move toward each other. At this time, the two ends of the building material have been fixed on the material detection assembly 2. The movement of the material detection assembly 2 toward each other will generate axial pressure on the building material. At this time, the pressure generated by the tension and pressure plate 31 on the tension and pressure arm 32 will be measured by the tension and pressure sensor 321 and recorded in the main controller 6. When the building material is deformed or damaged under the action of the axial pressure, the pressure value obtained by the tension and pressure sensor 321 is the maximum axial pressure load value of the building material.

[0053] Similarly, when the tensile load of the building material needs to be tested, the hydraulic push-pull rod 3 will drive the material detection assembly 2 to move in opposite directions, so that the building material generates axial tension. The tension generated by the tension-compression plate 31 on the tension-compression arm 32 is also measured and recorded by the tension-compression sensor 321 to obtain the maximum axial tensile load value when the building material is deformed or damaged under the action of the axial tension.

[0054] When the torsion load of the building material needs to be detected, the rotating drive motor 2123 will be started to drive the rotating drive gear 2122 to rotate. Since the rotating drive gear 2122 is meshed with the rotating teeth 221, when the rotating drive gear 2122 rotates, the rotating ring 22 will rotate under the drive of the rotating teeth 221, so that the torsion arm 24 rotates. At this time, the left and right symmetrical rotating rings 22 rotate in opposite directions respectively. When the rotating ring 22 rotates, the longitudinal clamping plate 232 and the transverse clamping plate 233 jointly apply a torsion force to the end of the building material. Since the symmetrical rotating rings 22 rotate in opposite directions, the two ends of the building material are respectively subjected to opposite torsion forces. At this time, the torsion arm 24 generates a torsion force on the torsion sensor 322. The torsion value of the end of the building material will be measured and recorded by the torsion sensor 322. When the building material is deformed or damaged under the torsion of the symmetrical material detection component 2, the torsion value obtained by the torsion sensor 322 is the maximum torsion load value of the building material.

[0055] When it is necessary to detect the shear load of the building materials, the lifting hydraulic rod 46 will be started and the pressure block 461 will rise. Since the building materials have been fixed on the material support plate 45 at this time, the pressure block 461 will be restricted by the building materials and pressed against the side wall of the building materials. The building materials will generate a shear force perpendicular to the axial direction of the building materials at the pressure point of the pressure block 461. The shear force of the pressure block 461 on the building materials will be measured and recorded by the shear force sensor set in the pressure block 461 until the building materials are deformed or damaged under the action of the shear force. At this time, the value obtained by the shear force sensor is the maximum shear load value of the building materials.

[0056] The device adaptively adjusts the clamping range through the material fixing component 23 and applies force in multiple directions to the clamped building materials, thereby effectively solving the technical problems that the building material detection devices in the prior art cannot adapt to building materials of different shapes and specifications and cannot simultaneously meet the requirements of detecting the pressure, tension, torsion and shear force of building materials, thereby improving the applicability and practicality of the building detection device and the detection efficiency of building materials.
