[0026] The present application will be described in detail below with reference to the drawings:
[0027] Overall structure:
[0028] The detection platform mainly comprises a workbench 1, a supporting arm 2 is vertically arranged on the workbench 1, a connecting rod 4 is slidably arranged on the supporting arm 2, an installation block 5 is connected to the connecting rod 4, an electromagnet 6 is arranged at the bottom of the installation block 5, an impact head is adsorbed on the electromagnet 6, a sleeve ring 10 is arranged on the impact head and the top of the supporting arm 2, and a safety rope 11 is connected between the two sleeve rings 10. An installation seat 13 is slidably arranged on the workbench 1, a first supporting rod 14 is hingedly connected to the installation seat 13, a head die 15 is installed on the first supporting rod 14, a second supporting rod 16 is hingedly connected to the top of the first supporting rod 14, and the other end of the second supporting rod 16 is hingedly connected to a sliding block 17, and the sliding block 17 is slidably installed on the installation seat 13.
[0029] Specific settings and functions of each component:
[0030] Support arm 2 and connecting rod 4 part: The first sliding table 3 is arranged on the support arm 2, and the connecting rod 4 is installed on the sliding end of the first sliding table 3. Through the first sliding table 3, the sliding position of the connecting rod 4 on the support arm 2 can be accurately controlled, and the height of the impact head is adjusted to meet the needs of different detection heights. The top of the mounting block 5 is provided with a threading groove 19 for the safety lock to pass through, and the caliber of the threading groove 19 is slightly larger than the safety cable 11. The position of the impact head can be limited through the threading groove 19, so that the impact head is roughly located at the middle of the electromagnet 6.
[0031] Impact head part: The impact head includes a base 7 and an impact block 9, and a sleeve ring 10 is arranged on the base 7 of the impact head. The base 7 is provided with a stud 8, and the impact block 9 is provided with a threaded hole matched with the stud 8. Through the threaded connection, different types of impact blocks 9 can be replaced to simulate different impact situations. The safety cable 11 connects the impact head and the sleeve ring 10 at the top of the support arm 2, which plays a protective role during the falling of the impact head, preventing the impact head from flying out and causing danger.
[0032] Head mold 15 adjustment part: The second sliding table 12 is arranged below the workbench 1, and the mounting seat 13 is installed on the sliding end of the second sliding table 12. Through the second sliding table 12, the position of the mounting seat 13 on the workbench 1 can be adjusted, so as to adjust the horizontal position of the head mold 15 to align with the impact head. The third sliding table 18 is arranged on the mounting seat 13, and the sliding block 17 is installed on the sliding end of the third sliding table 18. When the third sliding table 18 drives the sliding block 17 to slide, the sliding block 17 drives the first supporting rod 14 to rotate through the second supporting rod 16, thereby adjusting the angle of the head mold 15, realizing flexible adjustment of the head mold 15 at multiple angles, and improving the comprehensiveness of detection.
[0033] Other parts: One side of the workbench 1 is provided with a drawer 20, which is convenient for storing tools, impact heads of various models and other items used during detection, so as to make the working area more clean and orderly.
[0034] Working process:
[0035] In the process of impact detection of the fire helmet, the fire helmet to be detected is first installed on the head model 15. The third sliding table 18 is used to drive the sliding block 17 to slide, and the head model 15 is adjusted to the required detection angle. The horizontal position of the mounting seat 13 is adjusted by the second sliding table 12, so that the head model 15 is in a suitable detection position. Then, according to the detection requirements, the height of the impact head is adjusted by the first sliding table 3. The electromagnet 6 is turned on to attract the impact head. When the detection conditions are met, the power supply of the electromagnet 6 is turned off, and the impact head freely falls under the action of gravity to impact the fire helmet, and one detection is completed. The safety cable 11 ensures the safety of the falling impact head during the whole process. During the detection process, different impact blocks 9 can be replaced according to the requirements to simulate different impact conditions and comprehensively detect the impact resistance of the fire helmet.
[0036] The impact head can be manually placed for adsorption, or can be adsorbed by controlling the action of the components. When the impact head needs to be adsorbed, the second sliding table 12 is controlled to make the head model 15 away from directly below the electromagnet 6, and then the first sliding table 3 is controlled to make the electromagnet 6 descend until the impact head is adsorbed. If the impact head is adsorbed by controlling the action of the components, the length of the safety cable 11 should meet that the impact head does not contact the workbench 1 when the impact head naturally droops.
[0037] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
