Description

Technical Field

[0001] This utility model relates to the technical field of building material testing equipment, specifically a tensile testing device for testing building materials. Background Technology

[0002] In the field of construction engineering, the mechanical properties of building materials are the core indicators for evaluating their structural safety and durability. As a key device for testing the tensile properties of materials, the performance of tensile testing devices directly affects the accuracy and reliability of test results. However, existing tensile testing devices still have many technical defects and cannot meet the tensile testing needs of building materials. Therefore, developing a tensile testing device for testing building materials has important practical significance.

[0003] A tensile testing device for building materials, as described in CN221350875U, includes a main body and a disassembly mechanism disposed on the outer wall of the main body. The disassembly mechanism includes a locking assembly comprising a bolt and a slot. A lower placement platform is fixedly connected to the outer wall of the main body, and a sliding rod is slidably connected to the outer wall of the lower placement platform. A clamping rod is detachably connected to the outer wall of the sliding rod. By providing the slot, when the tensile testing device is used to test building materials, to improve the ease of clamping and positioning materials of different shapes, the bolt can be rotated according to the outer contour of the building material. The bolt slides from the inner wall of the slot through the action of the nut, and the clamping rod is pulled out from the outer wall of the sliding rod through the connecting groove. This facilitates the replacement of clamping rods of different shapes. As can be seen from the above, although this device can be applied well, it is generally not convenient for sequential testing of building materials at two different stations, making it difficult to achieve the expected testing efficiency. Further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a tensile testing device for testing building materials, so as to solve the problem that although the device proposed in the background art can be applied well, it is usually not convenient to conduct sequential testing of building materials in two stations, making it difficult for the device to achieve the expected testing efficiency for building materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tensile testing device for testing building materials, comprising a base, base plates fixed on both sides of the top of the base, a slide rail fixedly installed on the top of the base plates, a placement platform slidably installed on one side of the top of the slide rail, a first clamping mechanism installed on the top of the placement platform, a plurality of columns provided on the top of the base between the base plates, a top plate fixedly installed on the top of the plurality of columns, a motor installed at the bottom of the top plate, a drive gear installed through the top of the motor, a driven gear rotatably installed on the top of the top plate on one side of the drive gear, the driven gear meshing with the drive gear, a linkage shaft fixedly installed on the top of the driven gear, a bearing arm provided on the outer wall of one side of the linkage shaft, a control panel installed on the top of the base in front of the columns, the output terminal of the microcontroller inside the control panel being electrically connected to the first clamping mechanism and the input terminal of the motor respectively.

The input end of the first electric push rod is electrically connected to the output end of the microcontroller inside the control panel, and one end of the first electric push rod is connected to the outer wall of one side of the placement stage. The first electric push rod is provided to drive the placement stage to perform translation processing.

[0007] Preferably, the end of the support arm away from the linkage shaft is provided with a support frame, and a placement plate is fixed on one side outer wall of the lower end of the support frame. The placement plate is provided to accommodate the second electric push rod.

[0008] Preferably, a second electric push rod is installed at the center of the top of the mounting plate. The input end of the second electric push rod is electrically connected to the output end of the microcontroller inside the control panel. The bottom end of the second electric push rod passes through the mounting plate and is provided with a lifting plate. The second electric push rod is configured to drive the lifting plate to perform lifting and lowering operations.

[0009] Preferably, a second clamping mechanism is installed at the bottom of the lifting plate. The input end of the second clamping mechanism is electrically connected to the output end of the microcontroller inside the control panel.

[0012] (1) The drive gear is rotated by the motor. Since the drive gear and the driven gear mesh with each other and the diameter of the drive gear is smaller than that of the driven gear, the drive gear drives the driven gear to rotate slowly. The driven gear drives the placement plate to rotate through the linkage shaft and the bearing arm. The reciprocating rotation of the placement plate is moved to the top of the placement platform. The tensile test of building materials can be carried out in two stations in sequence, thereby improving the testing efficiency of building materials when using the tensile testing device.

Then, the second electric push rod is started to drive the lifting plate to move upward according to the predetermined force value. If the lifting plate moves upward, the lifting plate will drive the guide rod to slide upward inside the guide cylinder. At this time, observe whether the building material is deformed or broken, so as to determine whether the tensile test of the building material is qualified, thereby achieving the purpose of easily conducting tensile tests on the building material.

[0014] (3) The first electric push rod drives the placement platform to move forward, so that the placement platform slides on the top of the slide rail, so that the placement platform carries the building material above it to move forward and get closer to the staff, so that the staff can easily replace the building material, thereby improving the convenience of using the tensile testing device.

A bearing frame 10 is provided at the end of the bearing arm 9 away from the linkage shaft 21. A placement plate 11 is fixed on the outer wall of one side of the lower end of the bearing frame 10.

[0024] In use, the second electric push rod 14 is positioned by setting the mounting plate 11;

[0025] A second electric push rod 14 is installed at the center of the top of the mounting plate 11. The input end of the second electric push rod 14 is electrically connected to the output end of the microcontroller inside the control panel 2. The bottom end of the second electric push rod 14 passes through the mounting plate 11 and is provided with a lifting plate 13.

[0026] In use, the second electric push rod 14 is used to drive the lifting plate 13 to perform lifting and lowering operations.

[0027] A second clamping mechanism 12 is installed at the bottom of the lifting plate 13. The input end of the second clamping mechanism 12 is electrically connected to the output end of the microcontroller inside the control panel 2.

[0028] In use, the second clamping mechanism 12 is provided to cooperate with the first clamping mechanism 7 to clamp and fix the two ends of the building material.
