Description

Technical Field

[0001] The utility model relates to the technical field of concrete sampling, in particular to a concrete sampler. Background Art

[0002] In construction projects, it is often necessary to conduct quality inspections on completed projects. One of the most important items is the inspection of the concrete structure in the project. A coring machine is needed when sampling concrete.

[0003] At present, after the existing drilling coring machine completes coring, due to the small diameter of the coring barrel, the concrete sample will be squeezed against the inner wall of the coring barrel, so the concrete sample will remain in the coring barrel and will be difficult to remove. At this time, the staff needs to use external tools to continuously knock on the coring barrel. The manual repeated knocking process is not only laborious, but also makes the staff's sampling efficiency low. For this reason, we propose a concrete sampler to solve the above problems.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4A concrete sampler comprises a coring body 1, a coring barrel 2 is installed inside the coring body 1, and a protective cover 3 is provided on the side of the coring barrel 2. The sampling principle of the coring body 1 and the coring barrel 2 is the existing technology, which will not be described in detail here. A double-axis motor 4 is installed at the central position inside the protective cover 3, and the two ends of the double-axis motor 4 are symmetrically connected with a first rotating shaft 5. The double-axis motor 4 is an existing mature technology and can drive two groups of first rotating shafts 5 to rotate at the same time. Its specific working principle is not described in detail here. The outer sides of the first rotating shafts 5 are respectively sleeved with bevel gear sets 6, and the interiors of the bevel gear sets 6 are all inserted with second rotating shafts 7. The bevel gear sets 6 are composed of two groups of bevel gears, and the two groups of bevel gears are respectively sleeved on the outer sides of the first rotating shaft 5 and the second rotating shaft 7, and the bevel gears sleeved on the outer sides of the second rotating shaft 7 are connected to the inner wall of the protective cover 3 through bearings, thereby ensuring the stable rotation of the second rotating shaft 7, and the other end of the second rotating shaft 7 is connected with a knocking rod 8.

[0023] Further, see Figure 1 and Figure 2 It can be known that an electric telescopic rod 13 is connected to the lower side of the protective cover 3, and the bottom end of the electric telescopic rod 13 is connected to a mounting plate 14. The electric telescopic rod 13 is a prior art, and its telescopic range can be freely adjusted by the staff. The specific telescopic principle is not described in detail here. Since the electric telescopic rod 13 can be telescoped, it can drive the intermittent change of the position of the protective cover 3 to achieve the change of the knocking point, which can effectively improve the knocking effect on the core barrel 2, thereby accelerating the falling speed of the concrete sample.

[0024] Further, see Figure 2 It can be seen that the two ends of the protective cover 3 are symmetrically connected with connecting blocks 15, and the interior of the connecting blocks 15 is vertically inserted with vertical rods 16, and the bottom ends of the vertical rods 16 are fixedly connected to the mounting plate 14. When the electric telescopic rod 13 is working, the protective cover 3 can drive the connecting blocks 15 to slide along the outer surface of the vertical rods 16, and through the mutual cooperation of the connecting blocks 15 and the vertical rods 16, the electric telescopic rod 13 can be guided, thereby ensuring the stable lifting and lowering of the electric telescopic rod 13.

[0025] Further, see Figure 1 and Figure 2 It can be known that the mounting plate 14 is configured as a U-shaped structure, and the interior of the mounting plate 14 is connected to the coring machine body 1 by bolts. When in use, the mounting plate 14 configured with a U-shaped structure and in combination with the setting of bolts can realize the disassembly and assembly operations of the device and the coring machine body 1, thereby facilitating the staff to inspect the coring machine body 1 or the coring barrel 2.

[0026] Further, see Figure 2It can be known that a rubber block 9 is provided at the end of the knocking rod 8, and the rubber block 9 is set to a spherical structure. The rubber block 9 is made of rubber. The spherical setting of the rubber block 9 can effectively prevent the end of the knocking rod 8 from directly and rigidly contacting the outer wall of the core tube 2, thereby protecting the outer wall of the core tube 2.

[0027] Further, see Figure 3 and Figure 4 It can be known that a buffer spring 10 is connected to the side of the rubber block 9, and the other end of the buffer spring 10 is fixedly connected to the knocking rod 8. When in use, the elastic characteristics of the buffer spring 10 itself can further protect the core barrel 2.

[0028] Further, see Figure 4 It can be known that the sides of the knocking rod 8 are symmetrically distributed with fixed blocks 11, and the insides of the fixed blocks 11 are all inserted with guide rods 12, and the sides of the guide rods 12 are fixedly connected to the rubber blocks 9. When in use, the moving rubber blocks 9 can be guided by the mutual cooperation of the fixed blocks 11 and the guide rods 12, so as to effectively prevent the buffer spring 10 from being skewed, thereby effectively ensuring the service life of the buffer spring 10.

[0029] Working principle: When the utility model is in use, the staff can first move the device to take samples, and then drive the core barrel 2 to move down as a whole by turning the hand wheel. The purpose of sampling can be achieved through the continuous rotation of the core barrel 2. After the sampling is completed, the staff can rotate the hand wheel in the opposite direction, thereby driving the core barrel 2 to lift up as a whole, and then the staff can start the rotation of the dual-axis motor 4, thereby transmitting the rotational force to the first rotating shaft 5, and through the bevel gear set 6 sleeved on the outside of the first rotating shaft 5, the second rotating shaft 7 can be driven to reverse and rotate, and while the second rotating shaft 7 is rotating, it can drive the knocking rod 8 and the rubber block 9 to intermittently knock the outer wall of the core barrel 2, and in addition, it is equipped with an electric telescopic rod 13 installed at the bottom end of the protective cover 3. Through the extension and retraction of the electric telescopic rod 13, the position of the protective cover 3 can be adjusted, thereby realizing the change of the knocking point, so as to speed up the falling speed of the sample from the inside of the core barrel 2. The above is the entire working principle of the utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
