Description

Technical Field

[0001] The invention relates to the technical field of building block strength testing, in particular to a compressive strength testing device for autoclaved aerated concrete building blocks. Background Art

[0002] Autoclaved aerated concrete blocks, referred to as aerated concrete blocks, are a new type of lightweight, porous building wall material, which is widely used in construction projects. In order to ensure the strength and quality of the building, aerated concrete blocks need to be tested for compressive strength before use, that is, pressure is applied to the blocks through a press for testing. Compressive strength is an important indicator to measure its structural bearing capacity and durability. Only compliant and qualified aerated concrete blocks can be put into use.

[0003] However, as far as the currently available compressive strength testing device for aerated concrete blocks is concerned, the pressure acting on the blocks always starts from zero, and it takes a certain amount of time to reach the required pressure value. The testing efficiency is slow, especially when testing large quantities of blocks. It is time-consuming, has poor flexibility, and is not very practical. Summary of the invention

The testing component is pressed against the top of the block to be tested by a displacement push rod. The pressure push rod can realize the compressive strength test of the block through the testing component. The detection is convenient and flexible, and the operation is simple. When the testing component performs a compressive strength test on the block, it has an initial test pressure, that is, the pressure of the testing component does not start from zero when the test component is pressurized, thereby saving the time wasted by the traditional press starting from zero for the pressure test. The test is fast and efficient. At the same time, the testing component has a protection function. When the block is broken, the testing component can self-lock to avoid the test component being damaged due to the elastic impact caused by the loss of block support.

[0030] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment 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.

[0031] Please refer to Figures 1 to 11 As shown: Embodiment 1: The present invention provides a compressive strength test device for autoclaved aerated concrete blocks, including an installation assembly 1, the installation assembly 1 includes a test platform 101, a support frame 102, a displacement push rod 103, a connecting plate 104 and a pressure push rod 105, the support frame 102 is fixedly mounted on the top of the test platform 101, and the displacement push rod 103 is fixedly mounted on the top of the support frame 102, the connecting plate 104 is fixedly mounted on the bottom end of the push rod of the displacement push rod 103, and the pressure push rod 105 is fixedly mounted inside the connecting plate 104; it also includes a test assembly, the test assembly consists of a pressure mechanism 2 and a transmission mechanism 3; The pressure-applying mechanism 2 includes a pressure seat 201, a control panel 202 and a protective card block 203. The pressure seat 201 is fixedly mounted on the bottom end of the pressure push rod 105, and the control panel 202 is rotatably connected to the inside of the pressure seat 201, and the protective card block 203 is radially plugged into the inside of the pressure seat 201; the transmission mechanism 3 includes a transmission seat 301, a trigger block 302 and a linkage rod 303. The transmission seat 301 is plugged into the bottom of the pressure seat 201, and the trigger block 302 is axially plugged into the bottom of the transmission seat 301, and the linkage rod 303 is rotatably connected to the inside of the transmission seat 301.

[0032] Among them, the cross-sectional shapes of the top block of the trigger block 302 and the bottom block of the pressure seat 201 are both regular polygons, and a positioning groove 3011 is provided inside the transfer seat 301. The regular polygonal cross-sectional block parts of the trigger block 302 and the pressure seat 201 are partially inserted into the positioning groove 3011. In use, the installation component 1 can realize the regulation of the use position and test state of the test component, so as to facilitate the test of the compressive strength of the building block. After the building block to be tested is placed on the test platform 101 and located at a suitable position below the test component, the test component can be driven to rise and fall by controlling the extension and retraction of the displacement push rod 103. When the displacement push rod 103 is extended, it drives the test component to move downward, so that the transmission mechanism 3 is against the top of the building block for subsequent pressurization test. The pressurization test operation can be realized by extending the pressure push rod 105. It is easy to use and convenient to operate.

[0033] Wherein, the top of the trigger block 302 is provided with a switching top spring 3021, and the two ends of the switching top spring 3021 are respectively against the outside of the linkage rod 303 and the top of the trigger block 302. When the bottom of the trigger block 302 is not pressed by an external force, under the action of the switching top spring 3021, the bottom block of the trigger block 302 is exposed to the inside of the transfer seat 301. In use, the test assembly has two use states: a reset state and a test state. When the bottom of the transfer seat 301 does not contact the building block to be tested, the test assembly is in a reset state. When the bottom of the transfer seat 301 is pressed against the top of the building block to be tested, the test assembly is in a test state. When the test assembly is in the reset state, at this time, due to the trigger block 3 The part of the transmission seat 301 exposed outside 02 is not resisted or squeezed by external force, the outside of the linkage rod 303 is provided with a spiral linkage groove 3031, and the inside of the trigger block 302 is provided with a linkage protrusion 3022, and the linkage protrusion 3022 is inserted into the inside of the linkage groove 3031, so that under the action of the switching top spring 3021, the linkage protrusion 3022 is located at the bottom of the linkage groove 3031, and under the cooperation of the control groove 2022 and the control rod 2031, the protection block 203 is in a state of extending out of the pressure seat 201, and the protection block 203 is inserted in the topmost tooth groove of the protection tooth groove 3012 at this time, and when the displacement push rod 103 is extended, it drives the test assembly to move downward and When the transfer seat 301 contacts the top of the building block to be tested, the trigger block 302 is pressed by the building block to be tested, so that the trigger block 302 moves upward to the inside of the transfer seat 301 to hide and compress the switching top spring 3021. When the trigger block 302 moves upward, the linkage protrusion 3022 can drive the linkage rod 303 to rotate through the linkage groove 3031. The cross-sectional shape of the rod body at the top of the linkage rod 303 is a regular polygon, and a synchronization groove 2021 is provided inside the control panel 202. The rod body part of the linkage rod 303 with a regular polygonal cross-section is inserted into the synchronization groove 2021, and the rod body of the linkage rod 303 passes through the inside of the pressure seat 201. When the linkage rod 303 rotates, it can pass through the synchronization groove 202 1 drives the control disk 202 to rotate. An arc-shaped control groove 2022 is provided inside the disk body of the control disk 202, and a control rod 2031 is provided outside the protection card block 203. The control rod 2031 is plugged into the control groove 2022. When the control disk 202 rotates, the control groove 2022 can drive the protection card block 203 to move toward the inside of the pressure seat 201 through the control rod 2031, so that the protection card block 203 will be hidden inside the pressure seat 201 and lose the plug-in relationship with the protection tooth groove 3012. After that, the test assembly is switched to the test state to prepare for the subsequent pressurization action and the compressive strength test of the cut block. The two use states can be automatically switched, and the use is flexible and convenient.

[0034] Among them, a pressure top spring 2011 is provided at the bottom of the pressure seat 201, and the two ends of the pressure top spring 2011 are respectively against the inside of the transfer seat 301 and the bottom of the pressure seat 201. Under the cooperation of the transfer seat 301 and the pressure seat 201, the pressure top spring 2011 is in a pre-compression state. In use, when the test assembly is in the test state, that is, when the bottom of the transfer seat 301 is pressed against the top of the building block to be tested, the pressure seat 201 can be driven to move downward and compress the pressure top spring 2011 by extending the pressure push rod 105. After being compressed, the pressure top spring 2011 can increase its pressure on the transfer seat 301, and the pressure will be transmitted to the top of the building block to be tested through the transfer seat 301, thereby realizing the function of pressurized testing, and because the pressure top spring 2011 is in a pre-compression state when the test assembly is reset (it needs to be explained What is mentioned in this article is that the pressure top spring 2011 in the pre-compression state means that when the pressure seat 201 is located at the topmost point inside the transfer seat 301, the pressure top spring 2011 is still in a compressed state, thereby providing an initial supporting force between the pressure seat 201 and the transfer seat 301, and this force is the initial force and pre-compression force during the pressurization test). Therefore, when the pressure seat 201 moves downward, it is necessary to overcome the pre-compression force of the pressure top spring 2011, that is, the initial test pressure value at the beginning of the test is the pre-compression force. Thereafter, as the pressure seat 201 continues to move downward, the pressure top spring 2011 is continuously compressed to increase the test pressure and transmit it to the building block through the transfer seat 301 for testing, thereby eliminating the pressurization interval from zero to the pre-compression force, thereby realizing the function of quickly testing the compressive strength of the building block.

[0035] Among them, a distance sensor 3013 is provided inside the transfer seat 301, and the distance sensor 3013 can monitor the data of the displacement distance of the pressure seat 201 inside the transfer seat 301. During use, the distance sensor 3013 can monitor the downward movement distance of the pressure seat 201 inside the transfer seat 301. When the test component performs a compressive strength test on the building block, the pressure is generated by the compression of the pressure top spring 2011. Therefore, the downward movement distance of the pressure seat 201 inside the transfer seat 301 is the degree to which the pressure top spring 201 is compressed, that is, the test pressure. By controlling the moving distance of the pressure seat 201 inside the transfer seat 301, the maximum test pressure can be regulated. It is convenient and flexible to use, can adapt to different test requirements, and has strong flexibility and adaptability.

[0036] Among them, a protective tooth groove 3012 is provided inside the transfer seat 301, and the cross-sectional shapes of the outer end block of the protection card block 203 and the single tooth groove of the protection tooth groove 3012 are both right-angled triangles, and the tooth groove hypotenuse of the protection tooth groove 3012 and the block hypotenuse of the protection card block 203 are both set downward. In use, the test component has a protection function, that is, during the test process, if the building block is broken, the test component can be self-locking to avoid damage to the test component due to the elastic impact caused by the loss of building block support. During the test process, when the building block suddenly breaks, the resistance and extrusion effect of the bottom of the trigger block 302 disappears due to the breaking of the building block, so that under the action of the switching top spring 3021, the trigger block 302 will move down and extend out of the inside of the transfer seat 301, thereby restoring the test component to the reset state again. In the reset state, the protection block 203 will extend out of the pressure seat 201, so that the straight edge of the protection block 203 will be stuck in the straight edge of the protection tooth groove 3012, so that the use distance between the pressure seat 201 and the transfer seat 301 will not change due to the force of the pressure top spring 2011, thereby avoiding the phenomenon that the test assembly loses its supporting function after the building block is broken, and the pressure top spring 2011 will quickly extend and reset, causing the test assembly to be damaged due to elastic impact. It is stable to use, and after triggering the protection function, the test assembly is moved down to abut against the top of the test platform 101 so that the test assembly is in the test state again, and the pressure push rod 105 can be retracted to reset the test assembly as a whole, so that it can be used to test the remaining building blocks next time, and it has extremely strong flexibility and stability.

[0037] Specific usage and function of this embodiment: In the present invention, the installation component 1 can realize the regulation of the use position and test state of the test component, so as to facilitate the test of the compressive strength of the building block. After the building block to be tested is placed on the test platform 101 and is located at a suitable position below the test component, the test component can be driven to rise and fall by controlling the extension and retraction of the displacement push rod 103. When the displacement push rod 103 is extended, it drives the test component to move downward, so that the transmission mechanism 3 is in contact with the top of the building block for subsequent pressurization testing. The pressurization test operation can be realized by extending the pressure push rod 105. The test component has two usage states: reset state and test state. When the bottom of the transfer seat 301 does not contact the building block to be tested, the test component is in the reset state. When the bottom of the transfer seat 301 is pressed against the top of the building block to be tested, the test assembly is in the testing state. When the test assembly is in the reset state, the part of the trigger block 302 exposed outside the transfer seat 301 is not pressed against the external force. Therefore, under the action of the switching top spring 3021, the linkage protrusion 3022 is located at the bottom of the linkage groove 3031, and under the cooperation of the control groove 2022 and the control rod 2031, the protection block 203 is in the state of extending out of the pressure seat 201, and the protection block 203 is inserted in the topmost tooth groove of the protection tooth groove 3012. When the displacement push rod 103 is extended, it drives the test assembly to move downward and makes the transfer seat 301 contact with the top of the building block to be tested. At this time, the trigger block 302 is pressed by the building block to be tested. The contact is squeezed, so that the trigger block 302 moves upward toward the inside of the transfer seat 301 to hide and compress the switching top spring 3021. When the trigger block 302 moves upward, the linkage protrusion 3022 can drive the linkage rod 303 to rotate through the linkage groove 3031. When the linkage rod 303 rotates, it can drive the control disk 202 to rotate through the synchronization groove 2021. When the control disk 202 rotates, the control groove 2022 can drive the protection block 203 to move toward the inside of the pressure seat 201 through the control rod 2031, so that the protection block 203 will be hidden in the inside of the pressure seat 201 and lose the plug-in relationship with the protection tooth groove 3012. After that, the test assembly is switched to the test state to prepare for the subsequent pressurization action and the compressive strength test of the cut block. There are two usage states. It can be switched automatically. When the test assembly is in the test state, that is, when the bottom of the transfer seat 301 is pressed against the top of the building block to be tested, the pressure seat 201 can be driven to move downward and compress the pressure top spring 2011 by extending the pressure push rod 105. After being compressed, the pressure top spring 2011 can increase its pressure on the transfer seat 301, and the pressure will be transmitted to the top of the building block to be tested through the transfer seat 301, thereby realizing the function of pressurized testing. In addition, since the pressure top spring 2011 is in a pre-compressed state when the test assembly is reset (it should be noted that the pre-compressed state of the pressure top spring 2011 in this article means that when the pressure seat 201 is located at the topmost inside the transfer seat 301, the pressure top spring 2011 is still in a compressed state,Thereby, an initial supporting force is provided between the pressure seat 201 and the transfer seat 301, and this force is the initial force and pre-compression force during the pressure test). Therefore, when the pressure seat 201 moves downward, it needs to overcome the pre-compression force of the pressure top spring 2011, that is, the pressure value of the initial test at the beginning of the test is the pre-compression force. Thereafter, as the pressure seat 201 continues to move downward, the pressure top spring 2011 is continuously compressed to increase the test pressure and transmit it to the building block through the transfer seat 301 for testing, thereby eliminating the pressure interval from zero to the pre-compression force, thereby realizing rapid testing of the building block. The function of compressive strength detection is that the distance sensor 3013 can monitor the downward movement distance of the pressure seat 201 inside the transfer seat 301. When the test component performs compressive strength test on the block, the pressure is generated by the compression of the pressure top spring 2011. Therefore, the downward movement distance of the pressure seat 201 inside the transfer seat 301 is the degree of compression of the pressure top spring 2011, that is, the test pressure. By controlling the moving distance of the pressure seat 201 inside the transfer seat 301, the maximum test pressure can be regulated. It is convenient and flexible to use and can adapt to different test requirements. The test component has a protection function. That is, during the test process, if the test assembly can be self-locked when the block is broken, the test assembly can be prevented from being damaged due to the elastic impact caused by the loss of the block support. During the test process, when the block is suddenly broken, the resistance and extrusion effect at the bottom of the trigger block 302 disappears due to the breaking of the block. Therefore, under the action of the switching top spring 3021, the trigger block 302 will move downward and extend out of the inside of the transfer seat 301, thereby restoring the test assembly to the reset state again. In the reset state, the protection block 203 will extend out of the inside of the pressure seat 201, so that the straight edge of the block body of the protection block 203 will clamp the protection tooth groove 30 The straight edge of 12 ensures that the use distance between the pressure seat 201 and the transfer seat 301 will not change due to the force of the pressure top spring 2011, thereby preventing the pressure top spring 2011 from quickly extending and resetting after the block is broken, resulting in the test assembly being damaged due to elastic impact due to the loss of support function of the test assembly. The use is stable, and after the protection function is triggered, the test assembly is moved down to contact the top of the test platform 101 to put the test assembly in the test state again, and the pressure push rod 105 is retracted to reset the test assembly as a whole, so that it can be used for the next test of the remaining blocks.
