Description

Technical Field

[0002] Cement is a powdery hydraulic inorganic gelling material. It is an important gelling material and is widely used in civil construction, water conservancy, national defense and other projects. The various strength indicators of cement need to be tested and recorded using testing equipment. Generally, the flexural properties and compressive strength of cement are tested.

[0003] In the related art, the detection device for cement strength activity generally uses a flexural strength testing machine to test the flexural resistance of cement blocks, and uses a compressive strength testing machine to test the compressive resistance of cement blocks. The cement blocks are generally 40mmX40mmX160mm prisms. During the experiment, the cement blocks are bent by the flexural strength testing machine, and then the two halves of the cement blocks are subjected to a compressive strength test. The flexural strength testing machine and the compressive strength testing machine are generally two independent devices, resulting in a large footprint. During the test, the operator needs to transfer the broken cement blocks over a long distance. At the same time, the protective devices of the existing flexural strength testing machines and compressive strength testing machines need to be manually opened by the operator.

The surfaces of the first mounting plate 212 and the second mounting plate 213 are fixedly connected with the second gear 43 and the third gear 44, and the second gear 43 and the third gear 44 are meshed. The front of the mounting cylinder 211 is fixedly connected to the motor 41, and the output end of the motor 41 is fixedly connected with the first gear 42, the first gear 42 is meshed with the second gear 43, and the second gear 43 is meshed with the third gear 44. The front of the mounting cylinder 211 is movably connected with a rotating shaft, and the surface of the rotating shaft is rotated from the front to the back. The fourth gear 45 and the fifth gear 46 are respectively sleeved thereon, the fourth gear 45 meshes with the third gear 44, the diameter of the fourth gear 45 is smaller than the diameter of the fifth gear 46, the front face of the mounting cylinder 211 is movably connected with a winding wheel 47, the winding wheel 47 is provided with a gear with the fifth gear 46, the front face of the mounting cylinder 211 is provided with a slide groove, the interior of the slide groove is movably connected with a slide rod 48 and is connected to the inner circumferential surface of the first part 11, the top of the slide rod 48 is fixedly connected with a pull rope, the pull rope is movably connected with the winding wheel 47, the top of the base 6 is fixedly connected with a fixing plate 34, the surface of the fixing plate 34 is provided with an opening, the interior of the opening is movably connected with a support plate, the top of the base 6 is fixedly connected with a detection assembly 3, the connecting plate 35 of the detection assembly 3 is fixedly connected to the support plate, the bottom of the support plate is fixedly connected with a connecting plate 35, the two sides of the bottom of the connecting plate 35 are respectively fixedly connected with the first bending test piece 31 and the second bending test piece 32, and the bottom of the connecting plate 35 is fixedly connected with the compression test piece 33.

[0051] When in use, the operator first inserts the first support member 221 into the groove. Under the action of the magnet 23, there is a magnetic force between the magnet 23 and the inner wall of the groove, thereby simply assisting the first support member 221 to be fixed. Then the operator places the cement test block on the top of the first mounting plate 212 and the second mounting plate 213. The top of the first mounting plate 212 and the second mounting plate 213 is provided with a vertical plate 223, and a placement space is formed between the multiple vertical plates 223. The operator places the cement test block in the placement space. At this time, the cement test block is placed in the accurate position, avoiding the problem of manual adjustment of the position of the cement test block and consuming a lot of time and low accuracy. At this time, the first support member 221 is located at the center position of the bottom of the cement test block, and the height of the first mounting plate 212 and the second mounting plate 213 is level with the height of the first support member 221. Then the operator starts the motor 41 to rotate and drive the first gear 42 to rotate, thereby driving the second gear 43 and the third gear 44 to rotate, and the two second gears 43 and the third gear 44 are meshed, so that the two The second gear 43 and the third gear 44 rotate in opposite directions to the first mounting plate 212 and the second mounting plate 213. The first mounting plate 212 on the left rotates counterclockwise, and the second mounting plate 213 on the right rotates clockwise, so that the first mounting plate 212 and the second mounting plate 213 are separated from the cement test block. At this time, the anti-bending test top block 6 lifts up the cement test block, and then the operator starts the detection assembly 3 to retract, thereby driving the detection assembly 3 to move downward, and the first bending test piece 31 and the second bending test piece 32 apply downward pressure to both sides of the top of the cement test block, thereby bending the cement test block. During the rotation of the first mounting plate 212 and the second mounting plate 213, the second gear 43 and the third gear 44 drive the fourth gear 45 to rotate, thereby driving the rotating shaft and the fifth gear 46 to rotate, and then driving the winding wheel 47 to rotate. The winding wheel 47 reels the pull rope, so that the pull rope pulls the sliding rod 48 and the first section 2231 to move upward. At this time, the first section 2231 can prevent the splashing fragments of the cement test block from causing harm to the operator when the cement test block is broken;

[0052] When the operator needs to perform a compression test, the operator takes out the first support member 221, and then inserts the second support member 222 into the groove. Then, the operator places one section of the cement test block on the top of the second support member 222. In order to avoid the first mounting plate 212 and the second mounting plate 213 from contacting the first bending test piece 31 and the second bending test piece 32 and affecting the accuracy of the test, the operator similarly starts the motor 41 to rotate, thereby driving the first mounting plate 212 and the second mounting plate 213 to rotate, and then the operator starts the detection assembly 3 to contract. Similarly, the support plate, the connecting plate 35 and the compression test piece 33 move downward, and the compression test piece 33 presses the cement test block, thereby performing a compression test on the cement test block. The test process of the other half of the cement test block is similar. When the first mounting plate 212 and the second mounting plate 213 rotate, the first part 11 will automatically move up, thereby avoiding the operator manually operating the first part 11 to move up, thereby preventing the operator from forgetting to adjust the first part 11 to move up and causing cement test block fragments to splash and cause injury to the operator;
