Description

Technical Field

[0001] The utility model relates to the field of concrete detection, in particular to a concrete sample placement mechanism. Background Art

[0002] Concrete structures are widely used in modern buildings and infrastructure. Concrete is often exposed to acidic or alkaline environments, and it is prone to corrosion. The anti-corrosion parameter indicators of concrete are very important. Therefore, it is necessary to measure the anti-corrosion property of concrete to evaluate its anti-corrosion performance, which helps to ensure the long-term durability of concrete structures. The main test method is to obtain concrete samples from concrete structures and place the concrete samples in corrosive liquids. Generally, hydrochloric acid, sulfuric acid, sodium hydroxide or potassium hydroxide solutions are used for observation and testing as required. At present, laboratory personnel manually place the samples into the corrosion solution. This method requires the experimenter to use clamping pliers for placement. This process has high operation requirements and requires high concentration of attention. Since multiple samples need to be placed at one time for average comparison and there are many repetitive processes, it is easy to cause safety accidents if not careful. Therefore, in order to solve the above problems, a concrete sample placement mechanism is needed. Summary of the Utility Model

[0044] The grasping bracket is fixedly connected to the rotating part of the rotating component. The telescopic component is connected to the grasping bracket. The grasping bracket includes a vertical plate 8 and a horizontal plate 9. The horizontal plate 9 is connected to the lower end of the vertical plate 8. A reinforcing rib 10 plate is arranged between the horizontal plate 9 and the vertical plate 8.

[0045] Two groups of linear bearings 11 are arranged side by side on the horizontal plate 9. A guide post 12 is arranged in the linear bearing 11.

[0046] A grasping component is connected to the lifting end of the telescopic component. The grasping component includes a connecting frame and a clamping component. A guide hole with the same structure as the guide post 12 is formed on the connecting frame. The lower end of the guide post 12 is inserted into the corresponding guide hole.

[0047] The connecting frame includes a connecting plate 13. Two sets of grasping components are oppositely arranged at the bottom of the connecting plate 13. The two sets of grasping components are used to grasp the sample. The grasping component includes a grasping cylinder. A sliding plate 15 is connected to the telescopic end of the grasping cylinder. Guide rods 16 are respectively arranged at both ends of the inner side of the sliding plate 15. The guide rods 16 extend into the corresponding guide blocks 17.

[0048] Principle of the utility model: The utility model is located between the conveying device and the corrosion tank. The driving motor 4 drives the lead screw to rotate.

Since the fixed part of the rotating cylinder 6 is connected to the slider, and the grasping bracket is connected to the rotating part of the rotating cylinder 6. Therefore, the grasping bracket moves synchronously with the slider. The rotating part of the rotating cylinder 6 rotates 180 degrees, so that the grasping component is aligned with the sample. The telescopic cylinder 7 drives the grasping component towards the sample on the conveyor. The two sets of grasping components open, so that the sample is located between the two sets of grasping components. The clamping cylinder 14 drives the two sliding plates 15 to close, so that the two finger clips 18 fix the sample.

[0049] Then, the driving part drives the lead screw to rotate in the reverse direction. The rotation of the lead screw drives the slider to slide along the guide groove 3, so that the grasping bracket drives the sample to be directly above the corrosion tank. The rotating part of the rotating cylinder 6 rotates 180 degrees in the reverse direction so that the sample faces the corrosion tank. Then, the telescopic end of the telescopic cylinder 7 drives the grasping component to move downward, so that the sample is immersed in the corrosion tank. The telescopic cylinder 7 drives the grasping component towards the sample on the conveyor. The clamping cylinder 14 drives the two sliding plates 15 to open, so that the sample sinks into the detection solution pool.
