Description

Technical Field

[0001] This utility model relates to the field of cement performance testing technology, specifically a cement performance testing device. Background Technology

[0002] Cement is a powdered hydraulic inorganic binder that forms a paste when mixed with water. It can harden in air or water and can firmly bind materials such as sand and stone together. After the cement is mixed, cement mixtures are usually made into cement test blocks to test the performance of the cement.

[0028] The reciprocating structure 11 includes a fixed plate 111, a rotating rod 112, a driving wheel 113, a driven wheel 114, a cam 115, and a spring 116. The fixed plate 111 is fixed on the left and right sides of the bottom of the testing table 1. The rotating rod 112 passes through one side of the fixed plate 111 and is rotatably connected to the fixed plates 111 on both sides. The driving wheel 113 is fixed on the surface of the output shaft of the first motor 61.

The front and rear ends of the top of the first extrusion plate 10 are... Guide telescopic rods 18 are fixed on both sides, and the top of the guide telescopic rods 18 are fixedly connected to the bottom of the testing platform 1. When the first motor 61 is turned on, the output shaft of the first motor 61 will drive the drive wheel 113 to rotate, and the driven wheel 114 will drive the rotating rod 112 to rotate. The rotating cam 115 will push the first extrusion plate 10 down, so that the first extrusion plate 10 approaches the second extrusion plate 13 below. The springs 116 on both sides will be stretched. Through the continuous rotation of the cam 115, the first extrusion plate 10 will move up and down back and forth. The guide telescopic rods 18 on both sides will guide the first extrusion plate 10, so as to make the stability of the first extrusion plate 10 when moving up and down. The cement test block is crushed and recycled through the first extrusion plate 10 and the second extrusion plate 13.

[0029] The unloading structure 14 includes a second motor 141, a second threaded rod 142, a second threaded sleeve 143, and a push rod 144. The second motor 141 is fixed to the front and rear sides of the right side of the support frame 12. The second threaded rod 142 is rotatably connected to the front and rear sides inside the support frame 12, and the output shaft of the second motor 141 passes through the support frame 12 and is fixedly connected to one end of the second threaded rod 142. The second threaded sleeve 143 is threaded to the right side of the surface of the second threaded rod 142. The push rod 144 is hinged to the top of the second threaded sleeve 143, and the push rod 144 is inclined as a whole. The push rod 144 is angled, and the end of the push rod 144 away from the second threaded sleeve 143 is hinged to the bottom of the second extrusion plate 13. After the cement test block above the second extrusion plate 13 is crushed, the worker can turn on the second motor 141. The output shaft of the second motor 141 drives the second threaded rod 142 to rotate. The second threaded sleeve 143 moves on the surface of the second threaded rod 142, which causes the push rod 144 to push the second extrusion plate 13 above to move. When the second extrusion plate 13 tilts, the cement test block above the second extrusion plate 13 can be tilted out.

[0030] Guide grooves 20 are provided on both the front and rear sides of the bottom of the inner wall of the support frame 12. A guide block 19 is fixed below the second threaded sleeve 143, and the lower part of the guide block 19 extends into the interior of the guide groove 20 and slides in connection with the inner wall of the guide groove 20. When the second threaded rod 142 rotates, the guide block 19 below guides the second threaded sleeve 143, so that the second threaded sleeve 143 can only move horizontally left and right, thereby improving the stability of the second extrusion plate 13 when it is tilted.

[0031] Fixed rods 21 are fixed on the left and right sides of the front side of the testing table 1. A guide plate 4 is fixed at the front end of the fixed rod 21. The guide plate 4 is L-shaped. The bottom of the guide plate 4 is higher than the top of the second extrusion plate 13. When the pusher plate 9 pushes out the cement block, the guide plate 4 can guide the cement block so that the cement block can slide onto the surface of the second extrusion plate 13 for subsequent recycling.

[0032] Protective plates 15 are fixed on both the left and right sides of the front of the pusher plate 9, and the protective plates 15 are slidably connected to the surface of the testing table 1. The upper part of the protective plate 15 is arc-shaped. When the cement test block is tested for strength performance, the protective plate 15 can effectively protect the surrounding staff and prevent cement block fragments from causing injury to the surrounding staff.

[0033] Working principle: When the staff tests the strength performance of the cement test block, they first place the cement test block above the pressure detector 3. Then, the staff continuously applies pressure to the cement test block below using the pressing structure above the mounting platform 2, and tests the pressure through the pressure detector 3. When the cement test block on the surface of the pressure detector 3 breaks, the staff analyzes the strength performance of the cement test block based on the value detected by the pressure detector 3. After the test is completed, the staff can open the first motors 61 on both sides, which pushes the pusher plate 9 forward. The pusher plate 9 moves the broken cement test block on the surface of the pressure detector 3 forward, so that the tested cement test block falls onto the guide plate 4. The guide plate 4 guides the cement test block to the surface of the second extrusion plate 13. At this time, the tested cement test block is located in the second extrusion plate. Between the pressure plate 13 and the first extrusion plate 10, the output shaft of the first motor 61 reverses, causing the pusher plate 9 to move backward and return to its original position. The rotating rod 112 below rotates and drives the cam 115 to move, causing the first extrusion plate 10 to move up and down. The cement test block after testing is crushed and recycled through the second extrusion plate 13 and the first extrusion plate 10. After the pusher plate 9 moves back to its original position, the staff can place the cement test block to be tested again above the pressure detector 3. After the cement test block on the surface of the second extrusion plate 13 below is crushed, the staff can turn on the second motors 141 on both sides, causing the second extrusion plate 13 to tilt and pour out the crushed cement test block for recycling. This completes the testing operation of the cement test block.
