Description

Technical Field

[0001] This utility model relates to the field of cement sample preparation technology, and more specifically, to a high-strength cement sample preparation device. Background Technology

[0002] High-strength cement is produced using conventional processes from cement, sand, and stone raw materials, with the addition of water-reducing agents or simultaneously fly ash, mineral powder, slag, silica fume, and other additives. As a new type of building material, high-strength concrete is widely used in high-rise building structures, long-span bridge structures, and certain special structures due to its superior properties such as high compressive strength, strong deformation resistance, high density, and low porosity. In actual production of high-strength cement, a sample preparation device is required to prepare high-strength cement samples for subsequent testing.

[0003] The prior art discloses a mold for making cement samples, application number CN202022776469.8. In this invention, the high-strength cement in the sample making cylinder needs to be squeezed by an extrusion cap and an extrusion base to be formed. The extrusion structure is placed outside the air. When impurities are adsorbed on the surface of the extrusion structure, it will affect the extrusion structure to form the high-strength cement, reducing the success rate of this invention. At the same time, the surface of the formed high-strength cement sample will be uneven. There is no grinding structure, so it is impossible to treat the unevenness of the surface of the high-strength cement sample, which reduces the practicality of this invention.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a high-strength cement sample preparation device, which has the advantages of automatically cleaning impurities adsorbed on the surface of the extrusion structure and having a grinding structure that can grind the unevenness of the surface of the high-strength cement sample, thereby solving the problems mentioned in the background technology.

[0006] To achieve the advantages of automatically cleaning impurities adsorbed on the surface of the extrusion structure and having a grinding structure capable of grinding the unevenness of the surface of high-strength cement samples, the specific technical solution adopted by this utility model is as follows:

[0007] A high-strength cement sample preparation device includes a frame, an installation plate installed inside the frame, and multiple sets of sample cylinders fixedly passing through the upper part of the installation plate. Lifting boxes are installed above and below the installation plate. A grinding box is installed on one side of the frame, and a control panel is installed on the other side. Multiple sets of installation shafts pass through the opposing surfaces of the two sets of lifting boxes via bearings. An extrusion plate is installed at the end of each set of installation shafts on the same side near the installation plate. A worm gear is fixedly sleeved on the sidewall of each set of installation shafts on the same side away from the installation plate. Worms are installed inside the two sets of lifting boxes via bearings. Self-locking forward and reverse motors are installed on the sidewalls of the two sets of lifting boxes. The output ends of the two sets of self-locking forward and reverse motors are connected to the two sets of worms respectively via couplings. A first electric telescopic rod is fixedly passed through the upper and lower parts of the frame. Two sets of T-shaped rods slide through the upper and lower parts of the frame. The telescopic end of one set of the first electric telescopic rods on the same side and one end of the two sets of T-shaped rods on the same side are fixedly connected to one set of lifting boxes on the same side.

[0008] Furthermore, one set of worm gears on the same side meshes with multiple sets of worm wheels on the same side.

[0009] Furthermore, mounting covers are installed on both the upper and lower parts of the grinding box. Bearings penetrate the shaft tubes on the inner top and bottom surfaces of the grinding box. Bearings penetrate the two sets of mounting covers at the far ends of the two sets of shaft tubes. Connecting shafts slide through the interior of both sets of shaft tubes, and two sets of clamping plates are installed on the side walls of both sets of connecting shafts. Two sets of slots are provided on the inner walls of both sets of shaft tubes. Grinding wheels are installed on the opposing ends of the two sets of connecting shafts. A drive motor and a right-angle bracket are installed on the far side of both sets of mounting covers. A second electric telescopic rod penetrates the far end of both sets of right-angle brackets. The telescopic ends of the second electric telescopic rod are connected to the far ends of the two sets of connecting shafts respectively through bearings. The output ends of the two sets of drive motors are fixedly sleeved with main gears. The side walls of the two sets of shaft tubes are fixedly sleeved with driven gears. An opening is provided on one side of the grinding box, and a sealing cover is inserted into the opening. Mounting screws slide through the front and rear end faces of the grinding box. Clamping plates are installed at the opposing ends of the two sets of mounting screws. Two sets of mounting nuts are sleeved on the side walls of the two sets of mounting screws. The two sets of drive motors and the two sets of second electric telescopic rods are electrically connected to the control panel through wires.

[0010] Furthermore, the set of main gears on the same side and the set of driven gears on the same side mesh with each other.

[0011] Furthermore, the two sets of mounting screws and the four sets of mounting nuts are threadedly engaged with each other.

[0012] Furthermore, the control panel is connected by wires to two sets of the first electric telescopic rods and two sets of the self-locking forward and reverse motors.

[0013] Furthermore, two sets of support legs are installed on both sides of the frame.

[0014] Compared with the prior art, this utility model provides a high-strength cement sample preparation device, which has the following beneficial effects:

[0015] (1) This utility model adopts a lifting box. When the high-strength cement sample preparation device is actually used, the control panel is used to make two sets of self-locking forward and reverse motors work. The output ends of the two sets of self-locking forward and reverse motors can drive two sets of worm gears to rotate. Since one set of worm gears on the same side meshes with multiple sets of worm wheels on the same side, the rotating one set of worm gears on the same side can drive multiple sets of worm wheels on the same side to rotate. The rotating multiple sets of worm wheels on the same side can make the extrusion plate on the same side rotate through the mounting shaft on the same side. Using centrifugal force, the impurities adsorbed on the surface of multiple sets of extrusion plates on the same side can be thrown off. After cleaning, the control panel is used to extend the first set of electric telescopic rods below. When the multiple sets of extrusion plates below enter the interior of multiple sets of sample tubes, the high-strength cement can be put into the interior of multiple sets of sample tubes. Then, the control panel is used to extend the first set of electric telescopic rods above. The lowered multiple sets of extrusion plates can extrude the high-strength cement inside the multiple sets of sample tubes. Through the lifting box, the impurities adsorbed on the surface of the extrusion structure can be automatically cleaned, which improves the success rate of sample preparation of the high-strength cement sample preparation device.

[0016] (2) This utility model uses a grinding box. According to the above operation, after multiple high-strength cement samples are extruded and molded, the control panel is used to shorten the upper set of first electric telescopic rods and extend the lower set of first electric telescopic rods. At this time, the multiple sets of extrusion plates that move upward can push out the molded high-strength cement samples inside the multiple sets of sample cylinders and then move them into the grinding box. Then, the two sets of clamping plates move in opposite directions. Then, the two sets of mounting screws and four sets of mounting nuts are used to cooperate with each other. The operator rotates the four sets of mounting nuts clockwise and counterclockwise by hand. When the four sets of mounting nuts contact the grinding box, the clamping and installation of the high-strength cement samples is completed. Then, the opening is blocked with a sealing cap. The control panel is used to make the two sets of drive motors work. The output of the two sets of drive motors is... The output end can drive two sets of main gears to rotate. Since one set of main gears and one set of driven gears on the same side mesh with each other, the rotating two sets of main gears can drive the two sets of driven gears to rotate. The rotating two sets of driven gears can rotate two sets of connecting shafts and two sets of grinding wheels through two sets of shaft tubes. Then, using the control panel, two sets of second electric telescopic rods can be extended, which can make the two sets of grinding wheels move in opposite directions through two sets of connecting shafts. When the two sets of grinding wheels contact the high-strength cement sample, the surface of the high-strength cement sample can be ground. The processing of other high-strength cement samples is the same. With the grinding box provided, the grinding structure can grind the unevenness of the surface of the high-strength cement sample, which improves the practicality of the high-strength cement sample preparation device.

[0032] In one embodiment, the control panel is connected to two sets of first electric telescopic rods 6 and two sets of self-locking forward and reverse motors 12 via wires. The control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the art. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0033] In one embodiment, two sets of support legs are installed on both sides of the frame 1.

[0034] Working principle:

[0035] In actual use of the high-strength cement sample preparation device, the control panel is used to operate two sets of self-locking forward and reverse motors 12. The output ends of the two sets of self-locking forward and reverse motors 12 can drive two sets of worm gears 10 to rotate. Since one set of worm gears 10 on the same side meshes with multiple sets of worm wheels 11 on the same side, the rotating set of worm gears 10 on the same side can drive multiple sets of worm wheels 11 on the same side to rotate. The rotating multiple sets of worm wheels 11 on the same side can drive the extrusion plates 9 on the same side to rotate through the mounting shaft 8 on the same side. Using centrifugal force, impurities adsorbed on the surface of the multiple sets of extrusion plates 9 on the same side can be thrown off. After cleaning, the control panel is used to extend the first set of electric telescopic rods 6 below. When the multiple sets of extrusion plates 9 below enter the... When inserting high-strength cement into the multiple sample cylinders 3, the upper set of first electric telescopic rods 6 can be extended using the control panel. The lower set of extrusion plates 9 can then extrude the high-strength cement inside the sample cylinders 3. The lifting box 4 automatically cleans impurities adsorbed on the surface of the extrusion structure, improving the success rate of sample preparation using the high-strength cement sample preparation device. Furthermore, based on the above operation, after multiple high-strength cement samples are extruded and molded, the upper set of first electric telescopic rods 6 can be shortened using the control panel, and the lower set of first electric telescopic rods 6 can be extended. At this time, the lower set of extrusion plates 9 can then push out multiple sets of samples. The high-strength cement sample, formed inside sample cylinder 3, is then moved into the grinding box 5. Two sets of clamping plates 27 are then moved towards each other. Two sets of mounting screws 26 and four sets of mounting nuts 28 are threaded together. The operator manually rotates the four sets of mounting nuts 28 clockwise and counterclockwise. When the four sets of mounting nuts 28 contact the grinding box 5, the high-strength cement sample is clamped and installed. The opening 24 is then blocked with a sealing cap 25. Using the control panel, the two sets of drive motors 20 are activated. The outputs of the two sets of drive motors 20 can drive the two sets of main gears 21 to rotate. Since one set of main gears 21 on the same side and one set of driven gears 22 on the same side mesh with each other, the two sets of rotating gears... The main gear 21 can drive two sets of driven gears 22 to rotate. The rotating driven gears 22 can cause two sets of connecting shafts 15 and two sets of grinding wheels 23 to rotate through two sets of shaft tubes 14. Then, by using the control panel, two sets of second electric telescopic rods 19 can be extended, which can cause the two sets of grinding wheels 23 to move in opposite directions through the two sets of connecting shafts 15. When the two sets of grinding wheels 23 contact the high-strength cement sample, the surface of the high-strength cement sample can be ground. The processing of other high-strength cement samples is the same. The grinding box 5 is equipped with a grinding structure, which can grind the unevenness of the surface of the high-strength cement sample, thus improving the practicality of the high-strength cement sample preparation device.
