Description

Technical Field

[0001] This utility model relates to the field of engineering testing, and in particular to a device for testing the strength of concrete structures. Background Technology

[0002] Concrete structures are structures made primarily of concrete, including plain concrete structures, reinforced concrete structures, and prestressed concrete structures. Due to their unique and excellent properties and wide range of applications, they are widely used in construction engineering.

[0003] When testing the strength of concrete structures, a pressure testing device is usually used to test the pressure strength of concrete sample blocks. Specifically, a bearing platform and a pressing testing mechanism are set up, and the pressing testing mechanism includes a pressure block that is pressed against the concrete structure to be tested in a vertical direction. The pressure block applies pressure to the concrete sample block, and the strength of the concrete structure is detected by observing the data on the display screen.

[0004] However, the aforementioned device has certain drawbacks. For example, after the concrete sample block is tested, the surface of the support platform needs to be manually cleaned to remove fragments formed by the concrete sample block breaking under pressure, thereby preventing residual fragments from interfering with the testing of the next concrete sample block. However, when dealing with the testing of multiple concrete sample blocks, manual cleaning inevitably prolongs the testing time of a single concrete sample block, which in turn affects the overall testing rate and fails to meet the requirements of efficient testing.

[0005] Therefore, a concrete structure strength testing device is needed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a concrete structure strength testing device that can effectively shorten the time required to clean up fragments after a single concrete sample block measurement, thereby improving the subsequent testing rate.

[0007] To solve the above-mentioned technical problems, this utility model provides a concrete structure strength testing device, including a base plate, a support platform assembly, and a stamping testing mechanism;

[0008] The support platform assembly is disposed on the substrate and includes a waste collection cavity, a support plate, an annular conveyor belt, and a cleaning brush plate.

[0009] The support plate is fixed in the middle of the waste collection cavity;

[0010] The annular conveyor belt is installed inside the waste collection cavity via a drive unit and is sleeved on the outside of the bearing plate, overlapping with the upper surface of the bearing plate to support the concrete structure to be tested.

[0011] The annular conveyor belt has gaps between itself and both sides of the inner wall of the waste collection cavity;

[0012] The cleaning brush is disposed within the gap and flexibly adheres to the surface of the annular conveyor belt.

[0013] Furthermore, the minimum distance between the outer surface of the annular conveyor belt and the upper surface of the waste collection cavity is greater than the height of the concrete structure to be tested, so that the waste collection cavity can enclose the concrete structure to be tested.

[0014] Furthermore, both sides of the upper surface of the waste collection cavity are slidably fitted with sealing plates;

[0015] When the two closed plates are fitted together, an opening is formed for the stamping testing mechanism to extend into the waste collection cavity and contact the concrete structure to be tested.

[0016] Furthermore, the stamping detection mechanism includes a vertical plate, a cylinder, and a sensing pressure head;

[0017] The upright plate is disposed on the substrate and has an extension that extends to the top of the waste collection cavity;

[0018] The cylinder is mounted on the extension and one end is connected to the sensing pressure head.

[0019] The sensing pressure head is used to contact and compress the concrete structure to be tested, which is located above the bearing plate.

[0020] Furthermore, the upright plate is configured as an L-shaped structure.

[0021] Furthermore, the driving component is configured as a servo motor.

[0022] Furthermore, the end of the cleaning brush that contacts the annular conveyor belt is made of nylon.

[0023] Furthermore, a waste collection box is slidably installed in the middle of the waste collection cavity;

[0024] The waste collection box is located below the annular conveyor belt.

[0025] Compared with the prior art, the present invention has at least the following beneficial effects:

[0026] By setting up a support platform assembly including a waste collection cavity, a support plate, a ring conveyor belt, and a cleaning brush to support the concrete structure to be tested, the fragments formed by the concrete structure to be tested during the stamping testing mechanism will fall onto the surface of the ring conveyor belt. Therefore, in the subsequent cleaning process, no manual cleaning is required. Only the transmission of the ring conveyor belt needs to be controlled. The cleaning can be completed under the influence of gravity and the relative action between the cleaning brush and the ring conveyor belt. Thus, the cleaning time required can be effectively shortened, thereby improving the testing speed. Attached Figure Description

[0032] The concrete structure strength testing device of this utility model will be described in more detail below with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0033] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0034] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a concrete structure strength testing device, including a base plate 1, a support platform assembly 2, and a stamping testing mechanism 3.

[0035] The support platform assembly 2 is disposed on the base plate 1 and includes a waste collection cavity 21, a support plate 22, an annular conveyor belt 23, and a cleaning brush plate 24.

[0036] The support plate 22 is fixed in the middle of the waste collection cavity 21. The annular conveyor belt 23 is driven and installed inside the waste collection cavity 21, and is sleeved on the outside of the support plate 22, overlapping with the upper surface of the support plate 22 to support the concrete structure to be tested. That is, when it is necessary to test the concrete structure, the concrete structure to be tested can be placed in the area corresponding to the annular conveyor belt 23 on the support plate 22 to facilitate the rapid removal of crushed stone later.

[0037] It should be noted that, in order to reduce the influence of the annular conveyor belt 23 on the testing of the concrete structure, the thickness of the annular conveyor belt 23 is set to be much smaller than the thickness of the concrete structure to be tested, so as to ensure that the presence of the annular conveyor belt 23 will not cause a large error in the testing of the concrete structure.

[0038] The annular conveyor belt 23 has gaps on both sides of the inner wall of the waste collection cavity 21, and the cleaning brush 24 is disposed in the gaps and flexibly attached to the surface of the annular conveyor belt 23. It is used to perform secondary cleaning of impurities or gravel attached to the annular conveyor belt 23, so that the annular conveyor belt 23 located above the bearing plate 22 is always in a clean state, so as to ensure the accuracy of the next concrete structure test.

[0039] This device uses a support platform assembly 2, which includes a waste collection cavity 21, a support plate 22, a ring conveyor belt 23, and a cleaning brush 24, to support the concrete structure to be tested. When the stamping testing mechanism 3 performs the test, the fragments formed by the concrete structure to be tested will fall on the surface of the ring conveyor belt 23. Therefore, in the subsequent cleaning process, no manual cleaning is required. Only the transmission of the ring conveyor belt 23 needs to be controlled. The cleaning can be completed under the influence of gravity and the relative action of the cleaning brush 24 and the ring conveyor belt 23. Thus, the cleaning time can be effectively shortened, thereby improving the testing speed.

[0040] In one embodiment, to prevent the concrete structure under test from splashing during the testing process and causing injury to the testing personnel, the height of the waste collection cavity 21 is further limited.

[0041] Specifically, the minimum distance between the outer surface of the annular conveyor belt 23 and the upper surface of the waste collection cavity 21 is greater than the height of the concrete structure to be tested, so that the waste collection cavity 21 can wrap around the concrete structure to be tested. That is, the waste collection cavity 21 can form a wrap around the concrete structure to be tested. In this way, when the concrete structure to be tested is crushed under pressure, it can effectively intercept the gravel, thus achieving the purpose of ensuring the safety of the testing personnel.

[0042] In a further embodiment, a sealing plate 4 is added to further enhance the protection effect.

[0043] Specifically, both sides of the upper surface of the waste collection cavity 21 are slidably fitted with sealing plates 4. When the two sealing plates 4 are in contact with each other, an opening is formed for the stamping detection mechanism 3 to extend into the waste collection cavity 21 and contact the concrete structure to be tested. This ensures that the interception effect of the crushed stone is further improved without interfering with the stamping detection mechanism 3, thereby enhancing safety.

[0044] In other embodiments, a specific stamping inspection mechanism 3 is proposed to improve the inspection effect.

[0045] Specifically, the stamping detection mechanism 3 includes a vertical plate 31, a cylinder 32, and a sensing pressure head 33.

[0046] The upright plate 31 is disposed on the base plate 1 and has an extension that extends above the waste collection cavity 21.

[0047] The cylinder 32 is mounted on the extension and one end is connected to the sensing head 33.

[0048] The sensing pressure head 33 is used to contact and compress the concrete structure to be tested located above the bearing plate 22. The sensing pressure head 33 is a conventional technical means in the prior art, so it will not be described in detail here.

[0049] In a specific example, the upright plate 31 is configured as an L-shaped structure.

[0050] In other embodiments, the driving component that powers the annular conveyor belt 23 is further defined to meet the needs of batch inspection. Specifically, the driving component is a servo motor, and when the servo motor is running, the transmission length of the annular conveyor belt 23 is exactly half the circumference of the annular conveyor belt 23, so as to ensure that the area of ​​the annular conveyor belt 23 above the support plate 22 is always in a clean state, thereby improving the inspection effect.

[0051] In this embodiment, the end of the cleaning brush 24 that contacts the annular conveyor belt 23 is made of nylon material to improve the cleaning effect.

[0052] In other embodiments, a waste collection box 5 is slidably installed in the middle of the waste collection cavity 21. The waste collection box 5 is located below the annular conveyor belt 23 and is used for the recycling and cleaning of waste and gravel.

[0053] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
