Description

Technical Field

[0001] This utility model relates to the field of concrete strength testing technology, specifically to a strength testing device for durable concrete. Background Technology

[0002] Concrete durability refers to the ability of concrete to resist various destructive factors under actual use conditions and maintain its strength and appearance integrity over a long period of time. Because concrete durability is very important, strength testing devices are needed to test concrete durability to ensure that concrete can be used safely.

[0003] Patent document CN207263546U discloses a concrete compressive strength testing device, which states that "the use of a compression spring, a first compression block, a second compression block, and a compression rod in the concrete compressive strength testing device effectively reduces the pressure of the concrete test block on the concrete compressive strength testing device, protecting the device. The use of buffer blocks and buffer springs avoids unnecessary damage to the concrete test block caused by the compression block, and improves the accuracy of concrete compressive strength testing."

[0004] However, the testing devices mentioned in the above-mentioned documents mainly consider the problem that existing testing devices are prone to damaging concrete when testing it. However, when testing concrete, it is placed on a flat surface, which makes it impossible to test the strength of concrete when it is suspended in the air, resulting in an incomplete strength test of concrete.

[0005] In view of this, it is necessary to develop a strength testing device for durable concrete, which can then be used to test the strength of concrete located on a plane and suspended in the air. Utility Model Content

[0006] The purpose of this invention is to provide a strength testing device for durable concrete, so as to solve the technical problem mentioned in the background art that it is impossible to test the strength of concrete when it is suspended, resulting in an incomplete strength test of concrete.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a strength testing device for durable concrete, comprising: a support base, a testing platform installed on the top of the support base, through slots symmetrically opened on the top of the testing platform, two sets of support components symmetrically installed on the inner wall of the top of the testing platform, each support component including an electric push rod and a pushing block, the electric push rod being installed on the inner wall of the top of the support base, the pushing block being installed at the output end of the electric push rod, and the pushing block being located inside the through slot.

[0008] Preferably, a mounting bracket is installed on the top of the support base, and a controller is installed on one side of the mounting bracket.

[0009] Preferably, a hydraulic cylinder is installed on the top of the mounting frame. The hydraulic cylinder is connected to the controller, and the telescopic end of the hydraulic cylinder penetrates the inner wall of the top of the mounting frame. An installation sleeve is installed on the output end of the hydraulic cylinder. A pressure detector is installed inside the installation sleeve, and a pressure plate is installed on the detection end of the pressure detector.

[0010] Preferably, a through shaft is symmetrically installed through the top of the support base, and the through shaft is located in front of the detection table. A connecting plate is installed at the bottom end of the through shaft, and a buffer spring is installed at the top of the connecting plate. The buffer spring is located outside the through shaft, and the top end of the buffer spring is connected to the top inner wall of the support base.

[0011] Preferably, a buffer platform is installed at the top of the through shaft, and the buffer platform is located above the support base.

[0012] Preferably, the top of the buffer platform is symmetrically provided with mounting grooves, and rollers are installed on the top of the mounting grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, a support assembly is used to lift the concrete placed on top of the testing platform upwards, so that the concrete is supported and suspended in the air before pressure testing is performed. When the support assembly is in use, the electric push rod is started by the controller. The electric push rod drives the push block to move upwards. The push block moves upwards from the through slot to lift and support the concrete on top of the testing platform. Thus, the testing device can perform pressure testing on concrete on a flat surface, or it can support and suspend it in the air for pressure testing, making the concrete testing more comprehensive.

[0015] 2. In this utility model, when concrete is placed on top of the buffer platform, the through-axis moves downward to stretch the buffer spring, thereby buffering the impact force and preventing damage caused by direct placement on the device. Since the top of the buffer platform is equipped with rollers through the mounting groove, after the concrete is placed on the buffer platform, the height of the buffer platform is higher than the testing platform, and then it is pushed onto the testing platform. Under the action of the rollers, the concrete can be easily pushed to the top of the testing platform. Attached Figure Description

[0024] Please see Figure 1 , Figure 2 and Figure 3 A strength testing device for durable concrete;

[0025] The system includes: a support base 1 and a support assembly. A testing platform 8 is installed on the top of the support base 1. A through slot 9 is symmetrically opened on the top of the testing platform 8. Two sets of support assemblies are symmetrically installed on the inner wall of the top of the testing platform 8. The support assembly includes an electric push rod 10 and a push block 11. The electric push rod 10 is installed on the inner wall of the top of the support base 1. The push block 11 is installed at the output end of the electric push rod 10 and is located inside the through slot 9. A mounting frame 2 is installed on the top of the support base 1. A controller 3 is installed on one side of the mounting frame 2. A hydraulic cylinder 4 is installed on the top of the mounting frame 2. The hydraulic cylinder 4 is connected to the controller 3. The telescopic end of the hydraulic cylinder 4 penetrates the inner wall of the top of the mounting frame 2. A mounting sleeve 5 is installed at the output end of the hydraulic cylinder 4. A pressure detector 6 is installed inside the mounting sleeve 5. A pressure plate 7 is installed at the detection end of the pressure detector 6.

[0026] The support base 1 provides a location for the installation of the top testing platform 8, which provides a placement location for durable concrete testing. When concrete is placed on top of the testing platform 8, pressure testing is performed on the concrete by moving the pressure plate 7 downwards. The support assembly can lift the concrete placed on top of the testing platform 8 upwards, supporting and suspending the concrete before pressure testing. When in use, the controller 3 starts the electric push rod 10, which drives the push block 11 upwards. The push block 11 moves upwards from the through slot 9 to support the concrete on top of the testing platform 8. This allows the testing device to perform pressure testing on concrete on a flat surface or to support and suspend it for pressure testing, making the concrete testing more comprehensive. During testing, the hydraulic cylinder 4 drives the pressure plate 7 at the output end to move downwards, applying pressure to the concrete. During pressure application, the pressure detector 6 detects the pressure, and the detected pressure value is displayed on the screen on the controller 3.

[0027] Please see Figure 1 and Figure 4 A strength testing device for durable concrete;

[0028] The system includes a buffer platform 13, a through shaft 12 symmetrically installed on the top of the support base 1, and the through shaft 12 is located in front of the detection platform 8. A connecting plate 16 is installed at the bottom of the through shaft 12, and a buffer spring 17 is installed on the top of the connecting plate 16. The buffer spring 17 is located outside the through shaft 12, and the top of the buffer spring 17 is connected to the top inner wall of the support base 1. A buffer platform 13 is installed on the top of the through shaft 12, and the buffer platform 13 is located above the support base 1. The top of the buffer platform 13 is symmetrically provided with mounting grooves 14, and rollers 15 are installed on the top of the mounting grooves 14.

[0029] The through shaft 12 serves as a through connection. Before the concrete is placed on the testing platform 8, it is first buffered by the impact force generated during placement by the buffer platform 13, and then moved to the testing platform 8. Since the bottom of the buffer platform 13 is supported by the elastically installed through shaft 12, when the concrete is placed on the top of the buffer platform 13, the through shaft 12 moves downward to stretch the buffer spring 17, thereby buffering the impact force and preventing damage caused by direct placement on the device. Since the top of the buffer platform 13 is equipped with a roller 15 through the mounting groove 14, after the concrete is placed on the buffer platform 13, the height of the buffer platform 13 is higher than that of the testing platform 8, and then it is pushed onto the testing platform 8. Under the action of the roller 15, the concrete can be easily pushed to the top of the testing platform 8.

[0030] The working principle is as follows: First, the device is placed in the required position by the support base 1. When the concrete is placed, the impact force is buffered by the buffer platform 13, and then it is pushed into the top of the test platform 8. The hydraulic cylinder 4 drives the pressure plate 7 installed at the output end to move downward to test the pressure of the concrete. At the same time, the concrete can also be supported by the support component to test the pressure of the concrete in a suspended state.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
