Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a detection device for concrete mechanical properties. Background Art

[0002] As a basic material in the construction field, the quality of concrete's mechanical properties is directly related to the quality of the project and its safety in use. Therefore, testing the mechanical properties of concrete is an important part of ensuring the quality and safety of the project. Traditional concrete mechanical properties testing devices usually have problems such as complex operation, low test accuracy, and insufficient safety performance, and cannot meet the modern engineering requirements for efficient, accurate and safe concrete performance testing.

[0003] Existing detection devices usually do not protect concrete when testing concrete. During pressure testing, the concrete is subjected to pressure, causing fragments to collapse and scatter everywhere, affecting the personal safety of the testers. Therefore, we propose a detection device for the mechanical properties of concrete to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the defect in the prior art that the concrete is not protected during detection, resulting in the fragments being scattered everywhere, and proposes a detection device for the mechanical properties of concrete.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A detection device for concrete mechanical properties, comprising:

[0007] Base,

[0008] A hydraulic cylinder is arranged above the base and is used to perform pressure testing on concrete;

[0009] A pressing block, which is fixedly arranged at the output end of the hydraulic cylinder and is used for direct contact with the concrete;

[0010] The device also includes:

[0011] Two supports, both of which are fixedly arranged on the top of the base, and the hydraulic cylinder is arranged between the two supports;

[0012] A fixed cover, which is fixedly arranged on the top of the two supports;

[0013] The moving assembly is arranged on two supports and is used to enable the hydraulic cylinder to move up and down for easy testing;

[0014] The protection component is fixedly arranged on the top of the base and is used for protection when the concrete is subjected to pressure testing.

[0015] In a possible design, the moving component includes a moving block, two supporting sides close to each other are provided with grooves, the top inner walls and bottom inner walls of the two grooves are rotatably connected with screws, the two screws penetrate the moving block and are threadedly connected to the moving block, the tops of the two screws penetrate the bottom of the fixed cover and extend to the interior of the fixed cover, the tops of the two screws are fixedly sleeved with second bevel gears, and the two second bevel gears are connected to the same driving component.

[0016] In a possible design, the drive assembly includes a motor, which is fixedly arranged on one side of a fixed cover. The inner walls on both sides of the fixed cover are rotatably connected to the same rotating shaft. The output end of the motor passes through the fixed cover and is fixedly connected to the rotating shaft. Two first bevel gears are fixedly sleeved on the rotating shaft, and the two first bevel gears are respectively meshed and connected with the corresponding second bevel gears.

[0017] In a possible design, the protective assembly includes a second protective shell, which is fixedly mounted on the top of the base. The top hinge of the base is provided with a first protective shell. The second protective shell and the first protective shell are supported to form a cylindrical protective cover to protect the concrete inside.

[0018] In a possible design, a limiting block is fixedly connected to one side of the first protective shell, one of the supported sides is fixedly connected to two rotating seats, a fixed column is fixedly connected to the side where the two rotating seats are close to each other, a clamping block is slidably connected to the fixed column, a clamping slot is provided at the bottom of the clamping block, and the limiting block is clamped and connected to the clamping slot.

[0019] In a possible design, a fixing block is fixedly connected to the top of the base between two supports, and a scale is engraved on the top of the fixing block for centering the position when placing concrete to facilitate testing.

[0020] In the present application, firstly, the concrete is placed at the center of the fixed block according to the scale on the fixed block. Since the first protective shell and the second protective shell are semicircular, when the first protective shell is opened, the area of ​​the fixed block exposed to the outside can be increased to facilitate placing the concrete on the fixed block. Then the motor is started, and the motor drives the rotating shaft to rotate, so that the two second bevel gears meshing with the two first bevel gears on the fixed cover rotate, thereby driving the two screws to rotate, so that the moving blocks on the two screws can move up and down, so the hydraulic cylinder on the moving block also moves up and down to facilitate testing of concrete of different thicknesses. After the pressing block at the output end of the hydraulic cylinder fits the concrete, the motor stops working and waits for pressure testing.

[0021] Next, the first protective shell is closed, and the limit block on the first protective shell is clamped with the clamping block on one of the supports to fix the first protective shell, and then it is spliced ​​with the second protective shell and the two supports to form a cylindrical protective cover to protect the concrete. Then the hydraulic cylinder is started, and the pressing block at the output end of the hydraulic cylinder presses the concrete until the concrete is destroyed. The performance of the concrete is calculated by recording the pressing pressure value. During the process, the first protective shell and the second protective shell shield the concrete to prevent the concrete from being destroyed and causing the fragments to scatter everywhere, affecting the personal safety of the testers.

[0022] Beneficial effects:

[0023] In the utility model, the detection device for the mechanical properties of concrete is provided with a moving assembly to realize the up and down movement of the hydraulic cylinder, thereby facilitating the pressure test of concrete of different thicknesses and improving the test efficiency;

[0024] In the utility model, the detection device for concrete mechanical properties effectively protects the concrete during the test by setting a protection component, thereby preventing the concrete from collapsing during the test and ensuring the personal safety of the tester.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] Example 1

[0033] Referring to 1-3, a detection device includes a base 1, a hydraulic cylinder 6, a pressing block 601, two supporting members 2, a fixed cover 3, a moving component and a protective component.

[0034] The base 1 serves as the supporting foundation of the entire device and provides a stable installation platform for other components. The hydraulic cylinder 6 is arranged above the base 1 for pressure testing the concrete. The pressing block 601 is fixedly arranged at the output end of the hydraulic cylinder 6. When the hydraulic cylinder 6 is working, the pressing block 601 will directly contact the concrete and apply pressure.

[0035] The two supports 2 are fixedly arranged on the top of the base 1, and the hydraulic cylinder 6 is arranged between the two supports 2. This design makes the installation of the hydraulic cylinder 6 more stable. The fixed cover 3 is fixedly arranged on the top of the two supports 2 to form a closed space for protecting the internal drive components.

[0036] The moving assembly is arranged on the two supports 2, and is used to enable the hydraulic cylinder 6 to move up and down for easy testing. Specifically, the moving assembly includes a moving block 4. The two supports 2 are provided with grooves on one side close to each other. The top inner walls and the bottom inner walls of the two grooves are rotatably connected with screws 9. The two screws 9 penetrate the moving block 4 and are threadedly connected to the moving block 4. When the screw 9 rotates, due to the action of the thread, the moving block 4 will move along the axial direction of the screw 9.

[0037] The tops of the two screw rods 9 pass through the bottom of the fixed cover 3 and extend to the interior of the fixed cover 3, so as to be conveniently connected to the drive assembly. The drive assembly includes a motor 5, which is fixedly arranged on one side of the fixed cover 3 to provide power for the entire drive assembly. The inner walls on both sides of the fixed cover 3 are rotatably connected with the same rotating shaft 501. The output end of the motor 5 passes through the fixed cover 3 and is fixedly connected to the rotating shaft 501. In this way, when the motor 5 is working, the rotating shaft 501 will rotate accordingly. Two first bevel gears 502 are fixedly sleeved on the rotating shaft 501. The two first bevel gears 502 are respectively meshed and connected with the corresponding second bevel gears 901. The meshing transmission of the first bevel gear 502 and the second bevel gear 901 enables the two screw rods 9 to rotate synchronously.

[0038] The protection component is set up to ensure the safety of the test process. The protection component includes a second protection shell 8 and a first protection shell 7. The second protection shell 8 is fixedly set on the top of the base 1 to form a fixed protection part. The top hinge of the base 1 has a first protection shell 7, which can be opened or closed by rotation. When the first protection shell 7 is fitted with the second protection shell 8 and the support 2, a cylindrical protection cover is formed to protect the concrete inside it and effectively prevent the splash of debris generated during the test. Because the first protection shell 7 and the second protection shell 8 are semicircular, when the first protection shell 7 is opened, the open area can be increased to facilitate the placement of concrete on the fixed block.

[0039] The present application can be used in the field of concrete detection technology, and can also be used in other fields applicable to the present application.

[0040] Example 2

[0041] refer to Figure 2-3 , improved on the basis of the first embodiment: a detection device for concrete mechanical properties, which is applied to the technical field of concrete detection devices, in order to facilitate the fixing and opening of the first protective shell 7, a limiting block 701 is fixedly connected to one side of the first protective shell 7. One side of one of the supports 2 is fixedly connected to two rotating seats 201, and the two rotating seats 201 are fixedly connected to the side close to each other with a fixed column 202, and a block 203 is slidably connected to the fixed column 202. A bayonet is provided at the bottom of the block 203, and the limiting block 701 is connected to the bayonet by clamping. When the first protective shell 7 needs to be closed, it is only necessary to align the limiting block 701 with the bayonet and push the first protective shell 7 so that the limiting block 701 is clamped into the bayonet to achieve fixation. When the first protective shell 7 needs to be opened, it is only necessary to push the clamp 203 upward to make the bayonet out of the restriction of the limiting block 701.

[0042] In addition, in order to facilitate the centering of the position when placing the concrete, a fixing block 10 is fixedly connected between the two support blocks 2 at the top of the base 1. A scale is engraved on the top of the fixing block 10 for centering the position when placing the concrete, which is convenient for testing.

[0043] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 5 and the hydraulic cylinder 6 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
