Description

Technical Field

[0001] The utility model relates to the technical field of mortar test block sampling devices, in particular to a mortar test block rapid sampling device. Background Art

[0002] Mortar test blocks play a vital role in the construction industry. They are mainly used to evaluate the strength and quality of mortar. These test blocks are made by filling mortar into molds of specific sizes and curing them for a certain period of time. Before conducting compressive strength tests, the test blocks need to be cured strictly according to standard procedures. This process ensures the quality and reliability of the test blocks, making the test results more valuable for reference. In this way, we can verify whether the mortar meets the design requirements and specifications, ensuring the safety and durability of the building structure.

[0003] The following problems exist: In the process of sampling the mortar protective layer test block of the PCCP pipeline, the traditional operation method usually includes using wire or bandages to fix the test plate on the surface of the pipeline. The specific steps are to first wrap the wire or bandage around the pipe body, and then tie the test plate to the pipe body after wrapping the wire. Next, the operator will rotate the pipe body and use the mortar high-speed roller spraying technology to spray the sample. However, this method has some problems. First, when removing the mortar sample from the test plate, it is necessary to use repeated knocking and other means. This operation is not only inconvenient, but also easily causes the test block to break or the surrounding damage. These problems not only increase the difficulty of operation, but may also damage the integrity of the test block, thereby affecting the accuracy of the test results. Utility Model Content

Baffles 7 are installed on the outer walls of both sides of the test mold back plate 1. The two groups of baffles 7 and the partition 4 are combined with each other to form two groups of three-sided baffle mechanisms. The design of the baffles 7 makes it have bending characteristics and a certain elasticity. This structure enables the opposite surfaces of the two groups of baffles 7 to fit tightly against the outer walls of both sides of the test mold back plate 1, thereby effectively preventing mortar leakage. At the same time, it also ensures the sealing and stability of the test mold back plate during use, further improving the accuracy and reliability of the test. Through holes 8 are opened at both ends of the baffle 7, and the inner walls of the through holes 8 are fixedly connected with rubber hollow rings 91. The interior of the rubber hollow rings 91 is filled with soft cushioning cotton 92. The cushioning cotton 92 can effectively absorb impact force and reduce vibration. In addition, the rubber The inner wall of the hollow ring 91 is also fixedly connected to a sleeve 93. These sleeves 93 further enhance the stability of the structure. By arranging the rubber hollow ring 91 and the buffer cotton 92, not only can the reset speed of the baffle 7 after being subjected to external force be accelerated, so that it can quickly return to its original position, but it also ensures that the baffle 7 is more stable during the bending process, avoiding damage caused by severe vibration or impact, not only improving the service life of the baffle 7, but also enhancing its reliability in practical applications, ensuring the long-term stable operation of the equipment, the inner wall of the sleeve 93 is rotatably connected to a rotating rod 94, one end face of the rotating rod 94 is fixedly connected to a twist cover 95, and the outer edge of the twist cover 95 located on the opposite side of the sleeve 93 is fixedly connected to a rotating ring 96, the inner wall of the rotating ring 96 is rotatably connected to the other end of the outer wall of the sleeve 93, and the other end face of the rotating rod 94 is fixedly connected to a screw 97, and the screw 97 is threadedly connected to the inner wall of the nut 5.

[0034] Reference Figure 3 、 Figure 5 and Figure 6, which is a front sectional view of a mortar test block rapid sampling device disclosed in the present invention, a front sectional view of a bolt mechanism and a side view of a baffle. By setting a connection structure between the screw 97 and the nut 5, when a rotational force is applied to the twist cover 95, the rotating rod 94 and the screw 97 will rotate synchronously. During this rotation process, the screw 97 can move back and forth on the inner wall of the nut 5 to achieve smooth sliding. As the screw 97 is gradually withdrawn, the baffle 7 will bend due to the action of internal stress. At this time, the rubber hollow ring 91 in the through hole 8 will be squeezed by the sleeve 93, thereby deforming. At the same time, under the influence of the reaction force of the test block, the surface of the baffle 7 can smoothly detach from the surface of the test block, so that the test block can be quickly and completely removed from the mold. This process not only improves work efficiency, but also ensures that the integrity of the test block is not damaged. When the screw 97 continues to rotate and slowly extends into the interior of the nut 5, the baffle 7 and the rubber hollow ring 91 in the through hole 8 will gradually return to their original state. At the same time, the opposing surfaces of the two groups of baffles 7 will fit tightly with the outer walls of both sides of the test mold back plate 1 again, ensuring the stability and reliability of the entire device, and also improving the service life of the mold and the quality of the test block. By arranging the rubber hollow ring 91, buffer cotton 92, sleeve 93, rotating rod 94, twist cover 95, rotating ring 96 and screw 97, a bolt mechanism 9 can be formed.
