Description

Technical Field

[0001] The utility model relates to the technical field of concrete setting time detection, in particular to an automatic magnetic attraction device for the bucket cover of a full-automatic setting time measuring instrument. Background Technique

[0002] The detection of the concrete setting time is an important link in concrete quality control, which is used to ensure that the concrete reaches a certain strength within the specified time, so as to ensure the stability and durability of the concrete structure. The setting time of concrete refers to the time required for the concrete to reach a certain strength from the start of mixing. It is mainly divided into the initial setting time and the final setting time. The initial setting time refers to the time required for the cement paste to start losing plasticity from the start of mixing cement with water; the final setting time refers to the time required for the cement paste to completely lose plasticity and start to generate strength from the start of mixing cement with water. The concrete setting time is of great significance in construction. The initial setting time should not be too short to avoid the loss of plasticity of the concrete during transportation and pouring, which affects the construction quality; the final setting time should not be too long to ensure that the concrete can harden as soon as possible and improve the construction efficiency. At the same time, the setting time is also one of the important indicators for evaluating the performance of concrete and is of great significance for ensuring the strength and durability of the concrete structure.

[0003] At present, the opening and closing of the setting time bucket cover need to be carried out manually. During the detection process, in order to regularly observe and measure the setting state of the concrete, it is necessary to frequently open and close the bucket cover. Especially at the critical moments close to the initial setting and final setting, the test frequency may be higher, which leads to a large amount of repetitive labor. Usually, the detection of the concrete setting time will conduct tests on multiple samples simultaneously to ensure the accuracy and comparability of the results. This means that the detection personnel need to manage multiple setting time buckets simultaneously or in turn, and perform a series of operations such as opening the cover, observing, and recording, which greatly increases the workload.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-5 As shown, the automatic magnetic attraction device for the bucket cover of the full-automatic setting time measuring instrument includes a bottom plate 1. A support seat 2 is bolted to the middle of the top of the bottom plate 1. A fixed table 3 is fixed to the top of the support seat 2. A rotating disk 4 is sleeved outside the fixed table 3, and the rotating disk 4 is slidably connected to the fixed table 3. A indexing structure 5 is arranged below the rotating disk 4. A plurality of placement grooves 6 are formed on the surface of the top of the rotating disk 4, and a setting time bucket 7 is placed inside the placement groove 6. A bucket cover body 8 is placed on the top of the setting time bucket 7, and a lifting block 9 is bolted to the top of the bucket cover body 8. A servo motor 10 is fixed to the top of the fixed table 3, and a mounting table 11 is fixed to the top of the output shaft of the servo motor 10. A second motor 12 is installed above the mounting table 11. A rotating block 13 is rotatably connected to the surface of the front side of the mounting table 11. A connecting rod 14 is movably connected to the front side of the rotating block 13. A magnetic attraction block 15 is placed on the top of the left lifting block 9.

[0020] The output shaft of the second motor 12 passes through the mounting table 11 and is fixedly connected to the rotating block 13. One end of the connecting rod 14 is movably connected to the magnetic attraction block 15, and the connecting rod 14 is integrally arranged in an L shape. When the second motor 12 is turned on, the output shaft of the second motor 12 drives the rotating block 13 to rotate, thereby deforming the connecting rod 14, and the magnetic attraction block 15 can be pulled to move through the connecting rod 14.

[0021] The lifting block 9 is integrally circular, and the material of the lifting block 9 is iron. The magnetic attraction block 15 and the lifting block 9 are used in cooperation. When the staff opens the magnetic attraction block 15, the magnetic attraction block 15 placed above the lifting block 9 will adsorb the lifting block 9. When the magnetic attraction block 15 moves, the barrel cover body 8 can be lifted through the lifting block 9.

[0022] The indexing structure 5 includes a toothed ring 51, a first motor 52 and a gear 53. The toothed ring 51 is fixed to the bottom of the rotating disk 4. The first motors 52 are fixed to the left and right sides of the top of the bottom plate 1. The gear 53 is fixed to the top end of the output shaft of the first motor 52, and the gear 53 meshes with the toothed ring 51. A limiting ring 16 is fixed to the inner surface of the inner wall of the rotating disk 4, and a limiting groove 17 is formed on the outer surface of the fixed table 3. The limiting ring 16 is located inside the limiting groove 17 and is slidably connected to the inner wall of the limiting groove 17. When it is necessary to exchange the positions of the setting time buckets 7, the staff can turn on the first motors 52 on both sides, so that the output shafts of the first motors 52 drive the gears 53 to rotate, and the toothed ring 51 drives the rotating disk 4 above to rotate, causing the entire rotating disk 4 to rotate, and the limiting ring 16 also slides inside the limiting groove 17 to limit the rotating disk 4 through the limiting ring 16.

[0023] Working principle: When the staff conducts the concrete setting time detection, the staff pour the concrete to be detected into the interior of the setting time bucket 7 one by one and seal the setting time bucket 7 through the bucket cover body 8. After a period of time, the staff turn on the servo motor 10, so that the output shaft of the servo motor 10 drives the mounting table 11 to descend, making the magnetic attraction block 15 fall on the corresponding lifting block 9 surface. At this time, the staff turn on the magnetic attraction block 15 to make the magnetic attraction block 15 adsorb the lifting block 9. Then the staff turn on the second motor 12 above the mounting table 11, and then the rotating block 13 rotates. The connecting rod 14 will pull the magnetic attraction block 15 to move, and the bucket cover body 8 can be removed from the setting time bucket 7 through the magnetic attraction block 15. When the magnetic attraction block 15 is closed, the lifting block 9 will separate from the magnetic attraction block 15, and then the bucket cover body 8 will be put down. When it is necessary to open the setting time bucket 7 at other positions, the staff only need to turn on the first motor 52 below, and the rotating disk 4 can be rotated, and the position of the setting time bucket 7 above will change. When the corresponding setting time bucket 7 moves below the magnetic attraction block 15, the corresponding bucket cover body 8 can be lifted continuously through the magnetic attraction block 15, thus completing the opening operation of the setting time bucket 7.

[0024] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
