[0014] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the following description of the embodiments will be briefly introduced. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0015] Figure 1 A schematic diagram of the automatic heat preservation and sample delivery device for a falling hammer machine provided by the present invention; Among them: 100, sample insulation mechanism; 110, insulation box; 200, sample conveying mechanism; 210, conveying track; 220, robot arm assembly. Detailed Implementation

[0016] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0017] Figure 1 This is a schematic diagram of the automatic heat preservation and sample delivery device for a drop hammer test provided in this application. The device includes a sample heat preservation mechanism 100 and a sample delivery mechanism 200. The sample heat preservation mechanism 100 is used to store the sample to be tested and to keep the sample warm. The sample delivery mechanism 200 is used to deliver the sample to be tested to the drop hammer test station.

[0018] Specifically, the sample insulation mechanism 100 includes an insulation box 110 for storing the sample to be tested, which contains an insulation liquid. The sample to be tested is placed in the insulation box 110 and immersed in the insulation liquid. The insulation liquid keeps the sample to be tested warm, ensuring that the sample meets the preset temperature requirements when subjected to a drop hammer test.

[0019] The heat preservation liquid is industrial alcohol, and its chemical composition and mass percentage include: ethanol content ≥95.0%, methanol content ≤0.06%, water content ≤5%, and impurities controlled ≤0.5mg / L.

[0020] Preferably, the sample insulation mechanism 100 further includes a temperature regulating component for adjusting the temperature of the insulation liquid. This temperature regulating component includes a heating component for heating the insulation liquid and a cooling component for cooling the insulation liquid. The heating component includes an electric heating tube fixedly mounted at the bottom of the insulation chamber 110. The cooling component includes several condenser tubes evenly distributed on one side of the insulation chamber 110 and arranged equidistantly along the height of the insulation chamber 110.

[0021] It should be noted that the sample insulation mechanism 100 achieves cooling and heating functions through an external power supply.

[0022] In this embodiment, three condenser tubes are provided, and the distances between the three condenser tubes and the bottom of the insulation box 110 are 50mm, 100mm and 150mm respectively.

[0023] The sample conveying mechanism 200 is used to convey the sample to be tested stored in the sample insulation mechanism 100 to the drop hammer testing station. The sample conveying mechanism 200 includes a conveying track 210 and a robot arm assembly 220 that moves along the conveying track 210. The conveying track 210 includes a chain conveyor belt, and the robot arm assembly 220 moves back and forth with the chain conveyor belt.

[0024] It should be noted that the aforementioned insulated box 110 and the drop hammer testing station are both located directly above the displacement path of the robotic arm assembly 220. When the robotic arm assembly 220 moves directly above the insulated box 110, it can move downwards to grab the sample to be tested. Then, it moves with the chain conveyor belt to directly above the drop hammer testing station and then moves downwards again to place the sample to be tested at the drop hammer testing station, facilitating subsequent drop hammer experiments.

[0025] Preferably, the sample conveying mechanism 200 further includes a limiting component, which includes a first electrical limit switch and a second electrical limit switch. The first and second electrical limit switches are fixedly installed in preset positions. When the robot arm assembly 220 is directly above the insulation box 110, the first electrical limit switch closes, transmitting a first limit signal to the chain conveyor belt, causing the chain conveyor belt to stop running, allowing the robot arm assembly 220 to grasp the sample to be tested. When the robot arm assembly 220 is directly above the drop hammer testing station, the second electrical limit switch closes, transmitting a second limit signal to the chain conveyor belt, causing the chain conveyor belt to stop running, allowing the robot arm assembly 220 to place the sample to be tested at the drop hammer testing station.

[0026] Therefore, the technical solution of this application regulates the temperature of the heat preservation liquid through a temperature regulation component, realizing rapid cooling and heating of industrial alcohol, facilitating the setting of different sample conditions, and ensuring a stable industrial test temperature. A chain conveyor belt drives the movement of the robotic arm component 220, and the robotic arm component 220 realizes automatic sample gripping, effectively improving the sample conveying efficiency. At the same time, the limit switch realizes precise positioning, ensuring precise coordination between equipment and realizing the automation of drop hammer detection.

[0027] In addition to the above embodiments, the present invention may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
