Description

Technical Field

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

[0002] In the modern construction industry, concrete is one of the most widely used building materials. Its performance directly affects the safety and durability of building structures. From water conservancy facilities to underground engineering, concrete is ubiquitous, playing a key role in constructing the main structure of buildings and providing stable support. Among them, compressive strength is the key to ensuring the quality of the project. The concrete testing press is the core equipment used to test the compressive strength of concrete.

[0003] In the prior art, concrete testing pressure machines typically consist of a hydraulic system, a support platform, a pair of pressure plates, and a measurement and control system. When in use, the concrete block to be tested is usually placed in the center of the lower pressure plate, and the upper pressure plate is driven by the hydraulic system to apply pressure to the concrete. Finally, the compressive strength value of the concrete is obtained through the measurement and control system.

[0004] However, concrete specimens may break during pressure testing, and the resulting debris may remain on the surface of the lower pressure plate. This debris can affect the flatness of the contact between the specimen and the lower pressure plate during the next test, leading to uneven pressure distribution and thus causing deviations in the test results. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] Please see Figures 1 to 2 This utility model provides a technical solution: a concrete testing press, comprising a pressure device body 1, a support platform 3 fixedly connected to the surface of the pressure device body 1, an upper pressure plate 2 above the support platform 3, a lower pressure plate 4 fixedly connected to the surface of the support platform 3, a collection frame 5 sleeved on the surface of the lower pressure plate 4, a fixing plate 11 rotatably connected to the surface of the collection frame 5, a scraper 7 inserted into the surface of the fixing plate 11, the scraper 7 adhering to the surface of the lower pressure plate 4, and a rotatable fixing plate 11 and scraper 7 on the surface of the lower pressure plate 4. By setting a spring 12 and a limiting rod 10, the scraper 7 can be tightly adhered to the surface of the lower pressure plate 4 to clean residual residue and debris, improving the cleanliness of the lower pressure plate 4, thereby improving the accuracy and reliability of the pressure test results. The collection frame 5 on the surface of the lower pressure plate 4 can centrally collect and process the cleaned residue, improving cleaning efficiency.

[0024] Example 2

[0025] Please see Figures 1 to 4 Based on Embodiment 1, in order to collect concrete residue, the surface of the support platform 3 is provided with multiple grooves 16 arranged in a circular array. The grooves 16 are arc-shaped grooves, and elastic buckles 17 are fastened to the surface of the grooves 16. The elastic buckles 17 are arc-shaped plate structures and are fixedly connected to the bottom of the collection frame 5. By setting multiple grooves 16 arranged in an array, the collection frame 5 can be accurately positioned to ensure that the collection frame 5 can be accurately installed on the support platform 3 and maintain a relatively fixed positional relationship with the lower pressure plate 4. The elasticity of the elastic buckles 17 allows them to be easily fastened into or removed from the grooves 16, which facilitates the installation and disassembly of the collection frame 5 and makes it easier for workers to clean, maintain or replace the collection frame 5.

[0026] A side plate 6 is fixedly connected to the end surface of the collection frame 5 away from the elastic buckle plate 17. A rotating groove 13 is formed on the surface of the side plate 6. The rotating groove 13 is a circular groove with a "T" shaped cross section. A rotating shaft 8 is rotatably connected to the surface of the rotating groove 13. The rotating shaft 8 is a circular plate structure with a "T" shaped cross section. A fixing plate 11 is fixedly connected to the top of the rotating shaft 8. The fixing plate 11 is a square plate structure. A guide groove 14 is formed on the surface of the fixing plate 11. The guide groove 14 is a square groove.

[0027] Example 3

[0028] Please see Figures 1 to 5 Based on Embodiment 2, in order to clean the concrete residue remaining on the surface of the lower pressure plate 4, two limiting rods 10 are fixedly connected to both sides of the surface of the fixed plate 11. The limiting rods 10 have a T-shaped circular plate structure and consist of an outer circular plate and an inner circular plate. The diameter of the outer circular plate is larger than the diameter of the inner circular plate, thereby limiting the range of motion of the scraper 7. The limiting rods 10 play a limiting role for the scraper 7. The limiting rods 10 cooperate with the spring 12 to guide the extension and retraction direction of the spring 12. The surface of the limiting rods 10 is fitted with the spring 12, and the scraper 7 is inserted into the guide groove 14.

[0029] A top plate 9 is fixedly connected to the surface of the scraper 7. The top plate 9 has a square plate structure. Limiting holes 15 are opened on both sides of the surface of the top plate 9. The limiting rod 10 passes through the limiting holes 15. One end of the spring 12 is fixedly connected to the surface of the fixed plate 11, and the other end of the spring 12 is fixedly connected to the surface of the top plate 9. When the scraper 7 is in contact with the surface of the lower pressure plate 4, the spring 12 is in a stretched state, providing a downward pressure to the scraper 7, so that the scraper 7 can be tightly in contact with the surface of the lower pressure plate 4.

[0030] In actual use, firstly, the collection frame 5 is placed on the surface of the lower pressure plate 4. The elastic buckle 17 at the bottom of the collection frame 5 is aligned with the groove 16 on the surface of the support platform 3. After being squeezed by the surface of the support platform 3, the elastic buckle 17 deforms outward until it is fastened in the groove 16. The concrete is placed on the lower pressure plate 4. The upper pressure plate 2 moves downward under the drive of the pressure device body 1 to apply pressure to the specimen for testing. After the test, there will be debris and residue on the surface of the lower pressure plate 4. The operator rotates the fixing plate 11. The fixing plate 11 rotates around the rotation axis 8 as the axis. The fixing plate 11 drives the scraper 7 to rotate. When the scraper 7 is in contact with the surface of the lower pressure plate 4, the spring 12 is in a stretched state, so that the scraper 7 can always be in close contact with the surface of the lower pressure plate 4. During the rotation, the scraper 7 can scrape up the debris and residue on the surface of the lower pressure plate 4 and make it fall into the collection frame 5, thus completing the cleaning work on the surface of the lower pressure plate 4.

[0031] When it is necessary to empty the collection box 5, simply pry open the elastic buckle 17 to remove the collection box 5 from the support platform 3. This makes it easy to clean the waste inside the collection box 5, facilitates the installation and disassembly of the collection box 5, and makes it convenient for staff to clean, maintain or replace the collection box 5.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
