Description

Technical Field

[0001] This utility model relates to the field of engineering testing technology, specifically a sampling device for engineering testing and acceptance. Background Technology

[0002] Sampling devices for engineering testing and acceptance are specialized equipment used in the engineering field to obtain representative samples from engineering materials or structures for quality testing and acceptance. Cement is a basic building material with wide applications in engineering construction. It is one of the important raw materials for mixing concrete. Due to the long construction time of large-scale projects, cement may be stored in the factory for a long time. Long-term storage of cement may also affect its performance due to factors such as moisture. Therefore, it is necessary to sample and test cement regularly.

[0003] In the prior art, Chinese utility model patent CN217586473U discloses a cement sampling device for construction, including a sampling tube with a handle on one side. A vent hole is formed on the surface of the handle and is connected to the sampling tube. An adjustment component is located on one side of the sampling tube to adjust the connection between the vent hole and the sampling tube. A moving drive plate aligns the slot with the plate, and rotating the handle moves the drive plate synchronously until it reaches the other side of the two plates. At this point, the first and second sealing plates overlap to seal and block the channel, sealing one side of the sampling tube for easy sample removal. After the sample is removed, the drive tube moves the drive plate back to its original position, reconnecting the vent hole with the sampling tube, allowing the sample to be poured out. This more conveniently and stably seals the vent hole, preventing the sample from falling out of the sampling tube due to loose sealing by fingers.

[0004] However, while the above solution avoids the sample falling out of the sampling tube due to loose finger seal, it is inconvenient to sample cement at different depths in the same place at one time, or to use a single sampling tube to sample cement from multiple locations. Therefore, it does not meet the current requirements. In response, we propose a sampling device for engineering testing and acceptance. Utility Model Content

[0005] The purpose of this utility model is to provide a sampling device for engineering testing and acceptance, so as to solve the problems of the above-mentioned solutions in the background art, which avoid the sample falling out of the sampling tube due to the finger not sealing tightly, but are inconvenient to sample cement at different depths in the same place at one time, or to use a single sampling tube to sample cement from multiple places.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for engineering testing and acceptance, comprising a circular plate, six upper shells uniformly installed through the inner side of the circular plate, a sealing plug movably connected to the upper part of the upper shell, a lower shell provided on the lower end face of the upper shell, a bottom plate provided on the lower part of the lower shell, the bottom plate and the sealing plug being connected by a connecting rod, a cover plate movably provided on the lower end face of the lower shell through a limiting mechanism, a circular groove provided on the upper end face of the cover plate, a through hole provided through the bottom surface of the circular groove, a sealing mechanism installed on the inner side of the through hole, the sealing mechanism comprising a limiting ring and a connecting plate, the connecting plate being movably connected to the bottom plate through a rotary insertion mechanism.

[0009] Preferably, horizontal plates are provided on both sides above the connecting plate, the horizontal plates are connected to the connecting plate by a first spring, and a baffle is installed on the lower end face of the connecting plate.

[0010] Preferably, the horizontal plate is fixedly connected to the inner wall of the through hole, the baffle can be inserted into the inner side of the limiting ring, and the outer surface of the limiting ring is fixedly connected to the inner wall of the through hole.

[0011] Preferably, the limiting mechanism includes limiting posts, which are installed on both sides of the outer surface of the cover plate through round holes. A second spring is sleeved on the outer surface of the limiting posts. Insertion holes are provided on the lower sides of both sides of the outer surface of the lower housing, and the limiting posts can be inserted into the inner side of the insertion holes.

[0012] Preferably, the rotating insertion mechanism includes a base and a circular seat. The upper surface of the base is provided with a slot, the inner wall of the slot is provided with vertical grooves at the front and back, and an annular groove is provided below the vertical grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features six progressively longer lower housings, allowing for cement sampling at different depths. A rotating insertion mechanism and a limiting mechanism are incorporated. The cover plate is installed below the lower housing via the limiting mechanism. After the vertical plate is inserted into the vertical groove, rotating the cover plate 90 degrees causes it to engage with the annular groove. With the limiting post engaged with the insertion hole, the cover plate is securely installed. Pulling the pull plate moves the connecting rod upwards, causing the base plate and connecting plate to move upwards as well. The baffle moves away from the inner side of the limiting ring, creating a negative pressure environment between the baffle and the limiting ring. The gap is stored above the lower housing and the connecting plate. Then, under the action of the second spring, the connecting plate moves downward, causing the baffle to engage inside the limiting ring, sealing the limiting ring and preventing leakage of the sampled cement. After sampling is completed, the cement sample needs to be removed. After pulling the two limiting posts outward, the cover plate is rotated 90 degrees in the opposite direction to remove the cover plate from below the lower housing, thus obtaining the cement sample. This utility model can sample cement at different depths. By setting a sealing mechanism, it can prevent cement sample leakage and facilitate sample removal. Attached Figure Description

[0023] like Figure 1 and Figure 2 As shown, one embodiment of this utility model provides a sampling device for engineering testing and acceptance, including a circular plate 1. Six upper shells 2 are evenly installed through the inner side of the circular plate 1. A sealing plug 7 is movably connected to the upper part of the upper shell 2. A lower shell 6 is provided on the lower end face of the upper shell 2. A bottom plate 11 is provided on the lower part of the lower shell 6. The bottom plate 11 and the sealing plug 7 are connected by a connecting rod 15. A cover plate 5 is movably provided on the lower end face of the lower shell 6 through a limiting mechanism 13. A circular groove 16 is provided on the upper end face of the cover plate 5. A through hole 8 is provided through the bottom surface of the circular groove 16. A sealing mechanism 9 is installed inside the through hole 8. The sealing mechanism 9 includes a limiting ring 905 and a connecting plate 904.

[0024] A pull plate 4 is installed on the upper end face of the sealing plug 7. A sliding groove 12 is provided on the lower side of both sides of the inner wall of the lower housing 6. A slider 14 is slidably connected to the inner side of the sliding groove 12, and the outer surface of the slider 14 is fixedly connected to the outer surface of the base plate 11. The sealing plug 7, the connecting rod 15, and the base plate 11 can be driven to move upward by the pull plate 4, thereby improving the stability of the vertical movement of the base plate 11.

[0025] A handle 3 is installed in the middle of the upper end face of the circular plate 1. The upper shell 2 and the lower shell 6 are an integral structure. The length of the six lower shells 6 increases sequentially. A first mark is installed on the front end face of the cover plate 5, and a second mark is installed on the lower side of one side of the outer surface of the lower shell 6. The device can be moved by the handle to improve the stability of the connection between the upper shell 2 and the lower shell 6, and to facilitate the alignment of the cover plate 5 with the lower shell 6.

[0026] like Figure 3 As shown, horizontal plates 903 are provided on both sides above the connecting plate 904. The horizontal plates 903 are connected to the connecting plate 904 by the first spring 902. A baffle 901 is installed on the lower end face of the connecting plate 904. The horizontal plates 903 are fixedly connected to the inner wall of the through hole 8. The baffle 901 can be inserted into the inner side of the limiting ring 905. The outer surface of the limiting ring 905 is fixedly connected to the inner wall of the through hole 8, which improves the stability of the installation of the limiting ring 905 and the horizontal plates 903. The baffle 901 can block the limiting ring 905.

[0027] The limiting mechanism 13 includes a limiting post 1301, which is installed on both sides of the outer surface of the cover plate 5 through a round hole 1303. A second spring 1302 is sleeved on the outer surface of the limiting post 1301. Insertion holes 1304 are provided on the lower sides of both sides of the outer surface of the lower housing 6, and the limiting post 1301 can be inserted into the inner side of the insertion hole 1304. After the limiting post 1301 is inserted into the inner side of the insertion hole 1304, the cover plate 5 and the lower housing 6 can be connected.

[0028] like Figure 4 and Figure 5 As shown, the rotary insertion mechanism 10 includes a base 1001 and a circular seat 1002. The upper end face of the base 1001 is provided with a slot 1006. The inner wall of the slot 1006 is provided with vertical grooves 1003 at the front and rear. The lower part of the vertical grooves 1003 is provided with an annular groove 1004. Vertical plates 1005 are installed on the lower part of the front and rear ends of the circular seat 1002. The circular seat 1002 can be inserted into the inner side of the slot 1006. The vertical plates 1005 can be inserted into the inner side of the vertical grooves 1003. The vertical plates 1005 can move inside the annular groove 1004, which can connect the circular seat 1002 and the base 1001, thereby allowing the base 1001 and the connecting plate 904 to be pulled upward.

[0029] Working principle: In use, the six lower housings 6 of increasing length allow for sampling of cement at different depths. First, the cover plate 5 is installed below the lower housing 6 via the limiting mechanism 13. After the vertical plate 1005 is inserted into the inner side of the vertical groove 1003, the cover plate 5 is rotated 90 degrees, and the vertical plate 1005 is engaged with the inner side of the annular groove 1004. After the limiting post 1301 is engaged with the inner side of the insertion hole 1304, the cover plate 5 is stably installed. At this point, pulling the pull plate 4 moves the connecting rod 15 upwards, causing the base plate 11 and connecting plate 904 to move upwards. The baffle 901 moves away from the inner side of the limiting ring 905. At this time, the cement is under negative pressure, passing through the baffle 901 and the limiting ring. The gap between the rings 905 is stored above the lower housing 6 and the connecting plate 904. Subsequently, the connecting plate 904 moves downward under the action of the second spring 1302, causing the baffle 901 to engage inside the limiting ring 905, sealing the limiting ring 905 and preventing leakage of the sampled cement. After sampling is completed, the cement sample needs to be removed. After pulling the two limiting posts 1301 outward, the cover plate 5 is rotated 90 degrees in the opposite direction, and the cover plate 5 can be removed from below the lower housing 6 to obtain the cement sample. This utility model can sample cement at different depths. By setting the sealing mechanism 9, it can prevent cement sample leakage and facilitate sample removal.
