Description

Technical Field

[0001] This utility model belongs to the technical field of compressive strength testing devices, specifically relating to a compressive strength testing device for cement-modified mudstone. Background Technology

[0002] Cement-modified mudstone is a sedimentary rock produced by cement processing. After cement-modified mudstone is processed, it needs to be tested for compressive strength. This is usually done using a compressive strength testing device, and the existing compressive strength testing device is used for testing the compressive strength of cement-modified mudstone.

[0003] Existing compressive strength testing devices, when used to test the compressive strength of cement-modified mudstone, directly place the cement-modified mudstone on the surface of the test base plate and then press it down again for testing. After the test, when the mudstone is removed, a small amount of cement particles remain on the surface of the test base plate and the pressure plate due to the heavy pressure, which is not convenient for cleaning. This makes it easy to obstruct the placement of mudstone on the test base plate again, causing instability in the mudstone placement, reducing the accuracy of the test, and affecting the convenience of scraping and cleaning and the accuracy of measurement in the compressive strength testing device for mudstone compressive strength testing. Therefore, this utility model proposes a cement-modified mudstone compressive strength testing device. Utility Model Content

Detailed Implementation

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

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a compressive strength testing device for cement-modified mudstone, comprising a main body 100 including a base 101, a test base plate 102 disposed on the upper surface of the base 101, a pressure sensor 106 fixed at the connection between the lower surface of the test base plate 102 and the upper surface of the base 101, a top frame 104 fixedly installed at both ends of the upper surface of the base 101, two cylinders 105 fixedly installed at the top of the top frame 104, and a pressure plate 103 fixedly installed at the ends of the two cylinders 105 inside the top frame 104. The main body 100 of the compressive strength testing device also includes:

[0024] The cleaning and scraping mechanism includes a cleaning and scraping component located at the tail end of the upper surface of the base 101. One end of the cleaning and scraping component is located inside the top frame 104 and is equipped with a reciprocating adjustment component. The other end of the cleaning and scraping component is located inside the top frame 104 and is equipped with a limit sliding component. After the main body 100 of the compressive strength testing device is used for testing, the cleaning and scraping mechanism can clean the cement particles remaining on the surface of the test base plate 102 and the pressure plate 103. The cleaning is convenient, and the device can be placed stably and accurately for testing again.

[0025] To facilitate the removal of residual cement particles from the test base plate 102 and pressure plate 103 using a cleaning and scraping assembly, in this embodiment, preferably, the cleaning and scraping assembly includes a movable frame 1026 located at the tail end of the upper surface of the base 101. A locking bolt is rotatably mounted on the lower surface of the end of the movable frame 1026. Scrapers 1025 are fixedly mounted on both sides of the movable frame 1026 by screws, and the surface of the scrapers 1025 contacts the surface of the test base plate 102. The movable frame 1026 can drive the scrapers 1025 to move back and forth to contact the surfaces of the test base plate 102 and pressure plate 103 for cleaning, making cleaning convenient. When not cleaning, the movable frame 1026 can be moved to the tail end and the locking bolt can be rotated to press against the surface of the limiting slide rod 1028 to fix the movable frame 1026.

[0026] To facilitate the reciprocating movement of the movable frame 1026 and the scraper 1025 for cleaning via the reciprocating adjustment assembly, in this embodiment, preferably, the reciprocating adjustment assembly includes a limiting adjustment groove 1021 formed on one side of the top frame 104. A lead screw 1023 rotates inside the limiting adjustment groove 1021. A forward and reverse motor 1024 is installed at the end of the lead screw 1023 on the rear surface of the top frame 104, which facilitates the rotation of the lead screw 1023 by rotating the forward and reverse motor 1024. The outer surface of the lead screw 1023 is provided with a movable slide 1022, and the end of the movable slide 1022 is fixed to one end of the movable frame 1026 by screws. When the lead screw 1023 rotates, it drives the movable slide 1022 to move on the outer surface of the lead screw 1023, thereby moving the movable frame 1026 and the scraper 1025 to clean via the movement of the movable slide 1022.

[0027] In order to facilitate the stable movement of the moving frame 1026 and the scraper 1025 by means of the limiting sliding assembly, in this embodiment, preferably, the limiting sliding assembly includes a limiting slide rod 1028 fixedly installed inside the top frame 104 on the other side, and a limiting slide hole 1027 is opened at the other end of the moving frame 1026, and the limiting slide rod 1028 passes through the inside of the limiting slide hole 1027. When the moving frame 1026 is moved and adjusted, it can be controlled to slide on the outer surface of the limiting slide rod 1028 through the limiting slide hole 1027, which facilitates the stable control of the movement and cleaning of the moving frame 1026 and the scraper 1025.

[0028] The protective mechanism includes a protective component located at the connection between the edge of the test base plate 102 and the upper surface of the base 101. The edge of the protective component is provided with a fixing and mounting component, which can be fixed to the edge of the test base plate 102 for protection before testing, so that dirt is not easily obstructed from entering the lower surface of the test base plate 102.

[0029] To facilitate the protection of the edge of the test base plate 102 by means of a protective component, preventing cement particles and dirt from entering and obstructing the downward surface, in this embodiment, preferably, the protective component includes a rubber sleeve 1061 disposed on the edge of the test base plate 102. Both sides of the rubber sleeve 1061 are integrally provided with connecting side plates 1062, and the surface of the connecting side plates 1062 is in contact with the surface of the test base plate 102 and the base 101. The rubber sleeve 1061 can be fixedly installed at the edge of the test base plate 102 for protection, preventing dirt from entering and obstructing the test, and ensuring accurate testing.

[0030] To facilitate the fixed installation and protection of the rubber sleeve 1061 using the fixed installation assembly, in this embodiment, preferably, the fixed installation assembly includes a fixing screw 1063 inside the connecting side plate 1062. Both the upper surface edge of the base 101 and the edge of the test base plate 102 have internal threaded holes 1064, and the fixing screw 1063 is threaded into the internal threaded hole 1064. After the rubber sleeve 1061 is closed by the connecting side plate 1062, the fixing screw 1063 is rotated to embed into the internal threaded hole 1064, thus fixing and installing the rubber sleeve 1061.

[0031] The model number of the forward and reverse reversing motor 1024 in this utility model is 3420.

[0032] The working principle and usage process of this utility model are as follows: When using this cement-modified mudstone compressive strength testing device, firstly, the main body 100 of the compressive strength testing device is stably placed in the position of use through the base 101, and the main body 100 of the compressive strength testing device is powered on. The cement-modified mudstone to be tested is placed on the surface of the test base plate 102. The two cylinders 105 are moved simultaneously to drive the pressure plate 103 to move down until it contacts the surface of the mudstone and continues to move down. At this time, the test base plate 102 and the pressure sensor 106 at the bottom are subjected to force during the downward movement. The pressure sensor 106 is subjected to force and can be directly displayed on the display screen on the front surface. The displayed data is the compressive strength test data of the cement-modified mudstone.

[0033] Before using the compressive strength testing device body 100, the rubber sleeve 1061 is closed on the edge of the test base plate 102. The connecting side plate 1062 contacts the test base plate 102 to facilitate contact with the upper surface of the base 101. The rotating fixing screw 1063 is embedded in the internal threaded hole 1064 to fix the connecting side plate 1062, thereby facilitating the fixing of the rubber sleeve 1061 at the edge connection between the test base plate 102 and the base 101. This effectively protects the device during use and prevents falling cement particles from entering the interior and affecting the test results. Furthermore, the rubber sleeve 1061 can deform under pressure during the test without affecting the test results, thus improving the convenience of protecting the edge of the test base plate 102 when the compressive strength testing device body 100 is used for cement-modified mudstone compressive strength testing.

[0034] Finally, after the mudstone is removed from the main body 100 of the compressive strength testing device, the pressure plate 103 is lowered to a certain height and contacts the moving frame 1026. At this time, when cement particles remain on the surface of the pressure plate 103 and the test base plate 102, the forward and reverse motor 1024 can be energized to drive the lead screw 1023 to rotate. The rotation of the lead screw 1023 causes the moving slide 1022 to move within the limit adjustment groove 1021 on the outer surface of the lead screw 1023. When the moving slide 1022 moves stably, it drives the moving frame 1026 and the scraper. 1025 moves, and at the same time, the other end of the moving frame 1026 slides on the outer surface of the limiting slide rod 1028 through the limiting sliding hole 1027, which facilitates the stable movement of the moving frame 1026 and the scraper 1025. This allows the scrapers 1025 on both sides to contact the surfaces of the test base plate 102 and the pressure plate 103 respectively to scrape and clean them. This makes cleaning convenient. When testing again, the mudstone is stably placed on the surface of the test base plate 102 for accurate testing. This improves the convenience and accuracy of cleaning the main body 100 of the compressive strength testing device during cement-modified mudstone compressive strength testing.

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
