Description

Technical Field

[0001] The invention relates to the technical field of highway and water transport construction, and in particular to a sampling device for highway and water transport test detection. Background Art

[0002] Highway and water transport projects involve many aspects, and in order to improve the quality of the project as much as possible, it is necessary to test and inspect some of the materials used in highway and water transport. They can only be used if they meet the standards. Sampling is usually carried out during the test, such as sampling and testing of cement.

[0003] After searching, according to the patent network CN 220794650 U, a sampling device for highway water transport test and detection is published, including a top plate, a bottom column, a support plate and a top frame, and also includes a sampling component, the sampling component includes an electric push rod, a connecting frame, an insert cylinder, a rotating shaft, a bottom plate and a sampling cylinder; the sampling component includes a servo motor, gear one and gear two. The utility model belongs to the field of highway water transport construction technology, specifically a sampling device for highway water transport test and detection that can simultaneously perform sampling operations on cement at different heights, improve sampling efficiency, and has higher portability and improved practicality.

[0004] After searching, according to the patent network CN217006444U, a sampling device for highway and water transport test detection is announced, including a hollow cylinder, a partition plate is fixedly provided inside the hollow cylinder, two shells are provided inside the hollow cylinder, and the two shells are respectively arranged on both sides of the partition plate. A first opening is opened on the outside of the shell, and a second opening is opened on both sides of the hollow cylinder. The first opening is arranged on the top of the second opening, and a spring is provided at the bottom of the shell. The two ends of the spring are respectively fixedly connected to the bottom end of the shell and the bottom end of the hollow cylinder. A pushing mechanism is provided on the top of the hollow cylinder, and the shell is pushed to move for sampling through the pushing mechanism, and the pushing mechanism can be quickly adjusted to facilitate the pushing of the two shells. One sampling device can perform two sampling operations, which saves the use of sampling equipment, improves the sampling efficiency, and the overall operation is simple.

[0005] However, although the existing sampling device can perform good sampling operations on concrete of different depths when in use, after sampling the concrete, the sampling sleeve and the sampling bucket are not promptly disassembled and cleaned in a good manner, so that when the sampling sleeve and the sampling bucket are used for a long time, the subsequent sampling use of the sampling bucket will be affected due to the solidification of the concrete. In addition, when the sampling device is used daily, the hand operation length of the sampling device is not adjustable, and when the sampler's hand contacts the sampling device, the hand restraint effect of the sampler is not high, so that when the sampling device is lifted, there is a possibility of falling off. In addition, when the sampling device is used, the user's adjustment of the operating handle to different use states is not high, which reduces the user's comfort in holding the sampling device and does not meet people's use needs.
