Description

Technical Field

[0001] The utility model belongs to the technical field of concrete structure sampling, in particular to an on-site sampling device for a concrete structure. Background Art

[0002] Concrete refers to a mixture of binder, granular aggregate, water, and chemical admixtures and mineral admixtures that are mixed in appropriate proportions. After solidification, it is used as an important structural component of the building. In order to detect the construction quality of concrete, it is necessary to sample the concrete at the construction site and then test the obtained samples. Depending on different needs, some samples need to be taken before the concrete solidifies. When taking such samples, the sampling tube is generally inserted into the concrete to obtain the sample, and then the concrete sample in the sampling tube is poured out.

[0003] Generally, there are many locations that need to be sampled at the same project site, and continuous sampling is required for the concrete structure site. In this operating environment, after the concrete sample obtained in the sampling tube is taken out, the next sampling is often carried out directly, and there will generally be a small amount of concrete residue left in the sampling tube. This is the fusion of the concrete sampled last time and the concrete sampled now, resulting in deviations in some values ​​tested after sampling, that is, the test values ​​of the concrete sample are inaccurate.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0029] Furthermore, two second connecting rods 12 are installed on the side wall of the threaded sleeve 11, and a connecting rod 13 is fixedly installed at the bottom of the opposite ends of the two second connecting rods 12. The two connecting rods 13 are symmetrical to each other, and the ends of the two connecting rods 13 away from the second connecting rods 12 are respectively fixedly connected to the two moving rods 7. In this configuration, it is ensured that when the motor 9 is started, the motor 9 will be able to drive the threaded rod 10 to rotate, and when the threaded rod 10 rotates, it will be able to drive the threaded sleeve 11 to move downward. The second connecting rods 12 are arranged at both ends of the threaded sleeve 11, and the connecting rod 13 is installed at the bottom of the second connecting rod 12. At the same time, the connecting rod 13 is connected to the moving rod 7 in the moving mechanism.

[0034] The implementation principle of a concrete structure on-site sampling device of this embodiment is as follows: first, when it is necessary to sample the concrete body at the construction site, the staff can move the device to the location where sampling is required, and then the staff controls the motor 9 to start through the controller;

[0035] When the motor 9 is started, the motor 9 will be able to drive the threaded rod 10 to rotate, and when the threaded rod 10 rotates, it will be able to drive the threaded sleeve 11 to move downward, because the second connecting rods 12 are provided at both ends of the threaded sleeve 11, and the second connecting rod 12 is installed with a connecting rod 13 at the bottom, and the connecting rod 13 is connected to the moving rod 7 in the moving mechanism. When the threaded sleeve 11 moves downward, the moving rod 7 can move downward in the moving groove 8, and the moving rod 7 can drive the sampling tube 6 to sample the concrete body on the construction site;

[0036] When sampling is completed, the staff controls the motor 9 to start in reverse through the controller, and the threaded sleeve 11 moves upward, which can drive the sampling tube 6 to move upward. When the sampling tube 6 moves to a certain position, a collecting assembly is placed under the base 1, and the sampling tube 6 continues to move upward. When it moves to a certain extent, the concrete in the sampling tube 6 can be squeezed out of the sampling tube 6 under the squeezing of the squeezing plate 23 and fall into the collecting assembly.

[0037] When the threaded sleeve 11 moves upward, the movable rod 15 and the rotating assembly 14 can also pull the semicircular storage tray 17 to move horizontally, so that the two semicircular storage trays 17 are close to each other. When the sampling tube 6 moves up to disengage from the extrusion plate 23, the two semicircular storage trays 17 fit together. The staff can knock on the sampling tube 6 to make the concrete on the outside of the sampling tube 6 fall onto the semicircular storage tray 17.
