[0003] In the existing technology, the drop hammer impact testing machine cannot pre-treat the test sample under specified temperature and humidity conditions, requiring the tester to pre-treat the test sample under specified temperature and humidity conditions. However, the tester is required to take out the test pipe immediately after pre-treatment and complete the test within the corresponding time, which increases the difficulty of the test operation and cannot guarantee the scientific nature and accuracy of the test. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing drop hammer impact testing machines cannot pre-treat test samples under specified temperature and humidity conditions, requiring inspectors to pre-treat the test samples under specified temperature and humidity conditions. However, this requires inspectors to immediately remove the test pipes after pre-treatment and complete the test within a corresponding time, which increases the difficulty of the test operation and cannot guarantee the scientific nature and accuracy of the test. Therefore, an environmental chamber type drop hammer impact testing machine is proposed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 An environmental chamber-type drop hammer impact testing machine includes a frame 3, a drop hammer lifting and resetting assembly, a guide assembly, a hammer head 12, an insulated chamber 1 and a door 2 located on one side of the insulated chamber 1, a temperature and humidity control assembly, a controller 10 installed on the top of the insulated chamber 1, and a V-shaped plate 25.

[0023] One side of the insulated box 1 is connected to a temperature and humidity control component, which specifically consists of a cooling and heating unit 4 and an ultrasonic humidifier 6. The cooling and heating unit is model FL-03A, and the ultrasonic humidifier is model SM-03B.

[0024] The integrated cooling and heating unit 4 has a first air inlet pipe 5 on one side and the ultrasonic humidifier 6 has a second air inlet pipe 7 on one side. The first air inlet pipe 5 and the second air inlet pipe 7 are connected to the top of the heat preservation box 1.

[0025] The support frame 3 is fixedly installed on the insulation box 1. The support frame 3 is equipped with a drop hammer lifting and resetting assembly and a guide assembly. The guide assembly includes a guide tube 11. The bottom end of the guide tube 11 is connected to the insulation box 1. A hammer head 12 is slidably connected inside the guide tube 11. A sliding hole 14 is opened on one side of the guide tube 11. An adjusting screw 13 is threadedly connected to one side of the hammer head 12. The adjusting screw 13 passes through the sliding hole 14 and can adjust the height of the hammer head 12, enabling drop hammer impact tests at different heights. An electromagnet 16 is provided at the bottom of the hammer head 12. The electromagnet 16 is electrically connected to the controller 10. A test hammer 23 is slidably connected to the inner wall of the guide tube 11. A connecting rope 20 is bolted to the top of the test hammer 23. The connecting rope 20 passes through the hammer head 12 and is connected to the drop hammer lifting and resetting assembly. A V-shaped plate 25 is built into the insulation box 1.

[0026] The drop hammer lifting and resetting assembly includes a winding box 17 installed on one side of the top of the upright frame 3. A winding reel 18 is rotatably connected to the inside of the winding box 17, and a connecting rope 20 is wound around the outer surface of the winding reel 18. A rotating disc 19 is keyed to one side of the winding reel 18. A through hole 21 is opened on the inner side of the top of the upright frame 3, and the two ends of the through hole 21 are respectively connected to the winding box 17 and the guide tube 11. Multiple guide rollers 22 are rotatably connected to the inner wall of the through hole 21. A steering roller 15 is rotatably connected to the top of the hammer head 12. The connecting rope 20 is wound around the guide roller 22 and the steering roller 15.

[0027] Among them, the guide tube 11 is specifically a PP pipe, the insulated box 1 and the box door 2 are both assembled from polyurethane insulated, heat-insulating and flame-retardant wall panels, and the V-shaped plate 25 is specifically an alloy metal plate.

[0028] The outer surface of the test hammer 23 is embedded with multiple balls 24, and the balls 24 are in contact with the guide tube 11. The design of the balls 24 can reduce friction to a certain extent and improve the test accuracy of the test hammer 23. The top inner wall of the heat preservation box 1 is equipped with a temperature sensor 8 and a humidity sensor 9, and both the temperature sensor 8 and the humidity sensor 9 are electrically connected to the controller 10. The temperature sensor model is ATS1-82 and the humidity sensor model is AM2001.

[0029] The working principle of this embodiment is as follows: When a drop hammer impact test is required on a pipe or plate, the pipe or plate is first placed on the V-shaped plate 25, and the chamber door 2 is closed. At this time, the controller 10 controls the integrated cooling and heating unit 4 and the ultrasonic humidifier 6 to start, thereby adjusting the temperature and humidity according to different curing conditions of different samples. The temperature sensor 8 and humidity sensor 9 can visually monitor the temperature and humidity inside the insulation chamber 1 through the display panel on the controller 10. When the curing conditions are met, the impact test begins. At this time, the controller 10 cuts off the current to the electromagnet 16 at the bottom of the hammer head 12. After the test hammer 23 loses the attraction of the electromagnet 16, it moves downward along the guide tube 11 to conduct an impact test on the sample. After the test, the rotating disk 19 is rotated, which drives the winding disk 18 in the winding box 17 to rotate, thereby winding the connecting rope 20. Under the action of the rotating roller 15 and the guide roller 22, the test hammer 23 is driven to move upward along the guide tube 11. At the same time, the controller 10 connects the current to the electromagnet 16, and the electromagnet 16 regains its magnetism. When the test hammer 23 rises a certain distance, it will automatically attract the electromagnet 16, thereby completing the reset, so that it can be tested again next time.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
