Description

Technical Field

[0001] This application relates to the technical field of mortar test block compressive strength testing device, specifically a mortar test block compressive strength testing device. Background Technology

[0002] The compressive strength test of mortar specimens refers to the pressure that a mortar specimen can withstand per unit area under the action of external force, that is, the ability of the mortar specimen to resist compressive failure. This test needs to be performed on a corresponding compressive strength testing device.

[0003] Chinese utility model patent CN221377495U discloses a concrete test block compressive strength testing device, belonging to the field of concrete test block technology. It includes a test platform and a compressive strength testing mechanism set on the test platform. A storage groove for placing concrete test blocks is formed by protruding upward at the center of the top wall of the test platform. An inverted U-shaped receiving frame is also welded on the test platform. The compressive strength testing mechanism includes a pressure sensor installed on the bottom wall of the storage groove, a display screen and controller installed on the outer wall of the storage groove, a cylinder installed at the center of the top wall of the receiving frame, a telescopic rod connected to the bottom of the cylinder, a receiving platform welded to the bottom of the telescopic rod, and a lower pressing block installed below the receiving platform. The pressure sensor and the display screen are both coupled to the controller. A top groove is opened on one side wall of the receiving platform. The concrete specimen compression test device allows the shape of the lower pressure block to be changed according to the actual situation, thereby meeting different testing needs and expanding the scope of application. However, the above solution has the following drawbacks: the lower pressure block is pushed by a cylinder to test the compressive strength of the mortar specimen. During the contact process, the lower pressure block shakes under the force, resulting in poor stability. Furthermore, the disassembly and installation of the lower pressure block is cumbersome and inconvenient to use.

[0004] Therefore, this application provides a mortar specimen compressive strength testing device to solve the above problems. Utility Model Content

[0005] This application provides a mortar specimen compressive strength testing device, which aims to solve the problems in the prior art where the compressive strength test of mortar specimens is carried out by pushing the lower pressure block with a cylinder. During the contact process, the lower pressure block shakes under force, resulting in poor stability. In addition, the disassembly and installation of the lower pressure block is cumbersome and inconvenient to use.

[0006] To achieve the above objectives, this application provides the following technical solution: a mortar block compressive strength testing device, the mortar block compressive strength testing device comprising a compressive strength testing mechanism;

[0007] Preferably, to address the problems of instability and cumbersome disassembly and installation of the pressure block during compressive strength testing of mortar test blocks using a cylinder-driven pressure block, the compressive strength testing mechanism includes a base. A placement groove is fixedly connected to the top of the base. A pressure sensor is installed inside the placement groove, and a bearing block is installed on top of the pressure sensor. Operating brackets are fixedly connected to the tops of both sides of the base. Electric actuators are fixedly connected to the bottom of the operating brackets. A lifting block is fixedly connected to the output end of the electric actuator. A pressure block is installed at the bottom of the lifting block, and the pressure block is adapted to the internal dimensions of the placement groove and slidably connected to it. Limiters are fixedly connected to both sides of the lifting block. The operating bracket has guide rods fixedly connected inside the slots on both sides. Limiting blocks are located outside the guide rods and are slidably connected to them. Pressure blocks are installed at the bottom of the lifting block according to usage requirements. The lifting block is moved by an electric actuator, causing the limiting blocks on both sides to slide outside the guide rods, improving the stability of the lifting block's movement. The lifting block pushes the pressure blocks to apply pressure to the mortar test block placed on the bearing block, and the values ​​are displayed on the display panel for easy recording. By comparing the pressure values ​​of the mortar test block naturally placed on the bearing block inside the placement slot, the compressive strength value of the mortar test block can be obtained. This allows for convenient and quick testing of the mortar test block's compressive strength, improving pressure stability. The operation is simple, quick, and convenient.

[0008] Preferably, to address the issue of convenient compressive strength testing, a control switch is provided on one side of the top of the base, and a display panel is provided on the other side of the top of the base. Both the control switch and the display panel are electrically connected to the pressure sensor. The electrical connection between the control switch, the display panel, and the pressure sensor allows for better testing of the compressive strength of mortar blocks and is convenient to use.

[0009] Preferably, to solve the problem that the pressure block cannot be installed and replaced according to the size and shape of the mortar test block, mounting blocks are fixedly connected to the top two sides of the pressure block, and mounting grooves are opened on both sides of the inside of the lifting block. The mounting blocks are inserted into the mounting grooves, and fixing holes are opened on both sides of the mounting blocks. By sliding the sliding block, the sliding block slides outside the sliding rod. The sliding block compresses the spring set on the side, thereby causing the sliding block to drive the fixing rod to move into the inside of the operating groove. The pressure block inserts the mounting block into the mounting groove opened inside the lifting block. When the sliding block is released, the sliding block is subjected to the spring rebound force, causing the sliding block to push the fixing rod into the fixing holes opened on both sides of the mounting block, thereby fixing the mounting block inside the mounting groove. This facilitates the installation and disassembly of the pressure block and the lifting block, and the operation is simple, quick, and convenient to use.

[0010] Preferably, to address the issue of convenient operation of the sliding block, two sets of operating slots are provided on both sides of the lifting block. Multiple sets of operating slots are symmetrically arranged in pairs on both sides of the mounting slot. A sliding rod is fixedly connected inside the operating slot, and a sliding block is slidably connected to the outside of the sliding rod. A fixed rod is fixedly connected to the side of the sliding block closest to the mounting slot. The symmetrical arrangement of the operating slots on both sides of the mounting slot facilitates the sliding of the sliding block outside the sliding rod inside the operating slot, thereby facilitating the movement of the fixed rod by the sliding block and simplifying operation.

[0011] Preferably, in order to solve the problem of convenient fixing of the mounting block and the mounting groove, one end of the fixing rod extends into the interior of the mounting groove, and the end of the fixing rod set inside the mounting groove is adapted to the fixing hole. The fixing rod is inserted into the fixing hole, which can conveniently fix the mounting block inside the mounting groove. The operation is simple and quick, and it is easy to use.

[0012] Preferably, in order to solve the problem of the sliding block being easy to restore to its original state, a spring is sleeved on the outside of the sliding rod. The spring is fixedly connected between the side of the sliding block and the inside of the sliding rod. The spring facilitates the sliding block to restore to its original state and makes operation convenient.

[0013] This compressive strength testing mechanism, according to usage requirements, has a pressure block installed at the bottom of a lifting block. The lifting block is moved by an electric actuator, causing the limit blocks on both sides to slide outside the guide rod, improving the stability of the lifting block's movement. The lifting block pushes the pressure block to apply pressure to the mortar test block placed on the support block, and the numerical value is displayed on the display panel for easy recording. By comparing the pressure value of the mortar test block naturally placed on the support block inside the placement groove, the compressive strength value of the mortar test block can be obtained. This allows for convenient and quick testing of the compressive strength of mortar test blocks, improving pressure stability. It is simple, quick, and easy to use.

[0014] This compressive strength testing mechanism uses a sliding block to slide outside the sliding rod. The sliding block compresses a spring on its side, causing the sliding block to move the fixed rod into the operating slot. The pressure block then inserts the mounting block into the mounting slot inside the lifting block. When the sliding block is released, the spring's rebound force pushes the fixed rod into the fixing holes on both sides of the mounting block, thus fixing the mounting block inside the mounting slot. This facilitates the installation and removal of the pressure block and the lifting block, and is simple, quick, and easy to use. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Example 1

[0024] This embodiment provides a device for testing the compressive strength of mortar test blocks, such as... Figure 1-5 As shown, the mortar specimen compressive strength testing device includes a compressive strength testing mechanism 1.

[0025] When in use, the compressive strength testing mechanism 1 can be used to conveniently and quickly test the compressive strength of mortar test blocks. It is also convenient to disassemble and replace mortar test blocks of different sizes and shapes. The operation is simple, quick and easy.

[0026] Specifically, the compressive strength testing mechanism 1 includes a base 11, a placement groove 12 fixedly connected to the top of the base 11, a pressure sensor 13 disposed inside the placement groove 12, a bearing block 14 disposed on the top of the pressure sensor 13, an operating bracket 15 fixedly connected to the top of both sides of the base 11, an electric push rod 16 fixedly connected to the bottom of the operating bracket 15, a lifting block 17 fixedly connected to the output end of the electric push rod 16, a pressure block 18 disposed at the bottom of the lifting block 17, the pressure block 18 being adapted to the internal dimensions of the placement groove 12 and being slidably connected to the placement groove 12, limit blocks 21 fixedly connected to both sides of the lifting block 17, and guide rods 22 fixedly connected inside the slots on both sides of the operating bracket 15, the limit blocks 21 being disposed outside the guide rods 22 and being slidably connected to the guide rods 22;

[0027] In use, the pressure block 18 is installed at the bottom of the lifting block 17 according to the usage requirements. The lifting block 17 is moved by the electric actuator 16. The lifting block 17 drives the limit blocks 21 set on both sides to slide outside the guide rod 22, which can improve the stability of the movement of the lifting block 17. The lifting block 17 pushes the pressure block 18 to apply pressure to the mortar test block placed on the bearing block 14, and the value is displayed on the display panel 20 for easy recording. By comparing the pressure value of the mortar test block placed naturally on the bearing block 14 set inside the placement groove 12, the compressive strength value of the mortar test block can be obtained. It can conveniently and quickly test the compressive strength of the mortar test block, improve the pressure stability, and is simple, quick and easy to use.

[0028] Furthermore, a control switch 19 is provided on one side of the top of the base 11, and a display panel 20 is provided on the other side of the top of the base 11. Both the control switch 19 and the display panel 20 are electrically connected to the pressure sensor 13. The electrical connection between the control switch 19, the display panel 20 and the pressure sensor 13 can better test the compressive strength of the mortar test block and is convenient to use.

[0029] Example 2

[0030] Unlike Example 1, the pressure block 18 cannot be installed and replaced according to the size and shape of the mortar test block. Therefore, the top two sides of the pressure block 18 are fixedly connected with the mounting block 23, and the inner two sides of the lifting block 17 are provided with mounting grooves 24. The mounting block 23 is inserted into the mounting groove 24, and the mounting block 23 is provided with fixing holes 29 on both sides.

[0031] In use, by sliding the sliding block 27, the sliding block 27 slides outside the sliding rod 26. The sliding block 27 compresses the spring 30 set on the side, thereby causing the sliding block 27 to drive the fixed rod 28 to move into the inside of the operating groove 25. The mounting block 23 is inserted into the mounting groove 24 opened inside the lifting block 17 by the pressure block 18. When the sliding block 27 is released, the sliding block 27 is subjected to the rebound force of the spring 30, causing the sliding block 27 to push the fixed rod 28 into the fixing holes 29 opened on both sides of the mounting block 23, thereby fixing the mounting block 23 inside the mounting groove 24. This makes it easy to install and remove the pressure block 18 and the lifting block 17. The operation is simple and quick, and it is convenient to use.

[0032] Specifically, two sets of operating slots 25 are provided on both sides of the lifting block 17. Multiple sets of operating slots 25 are symmetrically arranged in pairs on both sides of the mounting slot 24. A sliding rod 26 is fixedly connected inside the operating slot 25, and a sliding block 27 is slidably connected outside the sliding rod 26. A fixed rod 28 is fixedly connected to the side of the sliding block 27 closest to the mounting slot 24. The symmetrical arrangement of the operating slots 25 on both sides of the mounting slot 24 makes it convenient for the sliding block 27 to slide outside the sliding rod 26 inside the operating slot 25, thereby facilitating the movement of the fixed rod 28 driven by the sliding block 27 and making operation convenient.

[0033] Furthermore, one end of the fixing rod 28 extends into the interior of the mounting groove 24, and the end of the fixing rod 28 located inside the mounting groove 24 is adapted to the fixing hole 29. The fixing rod 28 is inserted into the fixing hole 29, which can easily fix the mounting block 23 inside the mounting groove 24. The operation is simple and quick, and it is convenient to use.

[0034] Furthermore, a spring 30 is fitted around the outside of the sliding rod 26. The spring 30 is fixedly connected between the side of the sliding block 27 and the inside of the sliding rod 26. The spring 30 facilitates the sliding block 27 to return to its original shape, making operation convenient.

[0035] It should be noted that the pressure sensor 13, control switch 19, and display panel 20 are existing devices, and their working principle, size, and model are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0036] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
