Description

Technical Field

[0001] The utility model relates to the technical field of building material detection, in particular to a building material strength detection device for construction engineering detection. Background Art

[0002] Building materials are materials used in construction projects. The strength performance of building materials determines the quality of construction projects. During the testing process, the current building material strength testing device places the building materials on the testing device, and then uses the testing device to apply hammers of different intensities to the building materials. By observing whether the building materials are deformed and the degree of deformation, it is judged whether the strength performance of the building materials meets the standards.

[0003] However, the strength testing device for building materials currently used at construction sites has a relatively simple structure, with only a workbench and a testing mechanism for applying pressure, and no protective mechanism. During the testing process, the testers will stand next to the testing device to directly watch the testing process. If the strength performance of the building materials does not meet the standards, it is easy for them to be deformed, broken, and shattered by the pressure applied by the testing mechanism during the testing process. When the building materials break and shatter, they are prone to produce flying debris and fragments, which may cause harm to the testers standing nearby and watching. Utility Model Content

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a building material strength testing device for construction engineering testing includes a workbench 1 and a testing mechanism 2 located on the workbench 1, and also includes a stroke chamber 6 located in the workbench 1, wherein a lifting plate 7 is provided in the stroke chamber 6, wherein at least one and evenly arranged rotating screws 10 driven by a synchronous mechanism for synchronous rotation are provided in the stroke chamber 6, wherein the rotating screws 10 are all threadedly connected to the lifting plate 7, wherein a straight rod penetrating the lifting plate 7 is fixedly connected in the stroke chamber, and the synchronous mechanism includes a driving wheel 8 rotatably arranged in the stroke chamber 6 and a driven wheel 9 arranged oppositely, wherein the lower end of the rotating screw 10 is fixedly connected to the driving wheel 8 and the driven wheel 9, and the upper end is rotatably connected to the top of the inner wall of the stroke chamber 6, wherein the driving wheel 8 is provided with a synchronous belt 11 cooperating with the driven wheel 9, wherein the diameter of the driven wheel 9 close to one side of the driving wheel 8 is larger than that of the driving wheel 8 and the other driven wheel 9, and the tension of the synchronous belt 11 can be improved, and a driving motor with an output end fixedly connected to the driving wheel 8 is provided in the workbench 1.

[0022] Through the above structure, the synchronous mechanism can be used to cooperate with the rotating screw 10 and the straight rod to drive the lifting plate 7 to rise and fall in the stroke chamber 6, so as to protect the detection personnel. The specific structure is as follows:

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a return groove 5 is provided at the upper end of the stroke cavity 6 in the workbench 1, and a transparent protective plate 3 located in the return groove 5 is fixedly connected to the upper end of the lifting plate 7. The cross-section of the transparent protective plate 3 is a rectangle that matches the return groove 5, and the four corners of the transparent protective plate 3 are provided with limiting angle bars 4 that match the return groove 5. The surface of the limiting angle bar 4 fits with the inner wall of the return groove 5, which can improve the stability of the transparent protective plate 3 in the return groove 5 when lifting and lowering.

[0024] Through the above structure, the lifting and lowering of the lifting plate 7 can drive the transparent protective plate 3 to rise and fall. During the detection process, the transparent protective plate 3 rises, which can protect the detection personnel next to the workbench 1.

[0025] Embodiment 2

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the workbench 1 is provided with a control module electrically connected to the detection mechanism 2 and the drive motor.

[0027] Through the above structure, before opening the detection mechanism 2 to detect the strength of the building materials, the driving motor will automatically drive the transparent protective plate 3 to rise, and the detection mechanism 2 will start. After the detection is completed, the detection mechanism 2 stops running, and the control module will control the driving motor to drive the transparent protective plate 3 to descend.

[0028] During the specific implementation of the utility model, when it is necessary to detect the strength of the building materials, the building materials are placed on the workbench and placed under the detection mechanism, and the strength of the building materials is detected by using the pressure applied by the detection mechanism. During the detection, the detection mechanism is turned on, and under the action of the control module, the detection mechanism will start with a delay, and the control module will first turn on the driving motor, and the driving motor drives the driving wheel to rotate, and under the cooperation of the synchronous belt, the driven wheel will rotate accordingly, thereby driving all the rotating screws to rotate synchronously in the same direction, and under the cooperation of the straight rod, the lifting plate will rise in the stroke cavity;

[0029] Since the transparent protective plate is fixedly arranged on the upper end of the lifting plate, the lifting of the lifting plate will drive the transparent protective plate to rise in the return groove. When the transparent protective plate is lifted to a certain height, the driving motor is turned off and the detection mechanism is operated. During the detection process, the transparent protective plate can prevent the flying debris and fragments of the building materials from causing harm to the detection personnel. The detection personnel can watch the detection process through the transparent protective plate. After the detection is completed, the detection mechanism stops running, and the control module controls the driving motor to drive the driving wheel to rotate in the opposite direction, thereby lowering the transparent protective plate.
