TECHNICAL FIELD

[0001] The application belongs to the technical field of pressure test, and specifically discloses a traffic safety glass stud pressure test device. BACKGROUND

[0002] Studs, a commonly used traffic barrier, are used to guide people to travel in the correct direction, prevent overspeed and traffic accidents. They are mainly used in highways and railways. There are many types of studs, which can be roughly divided into three categories: inverse reflection method of three-dimensional right-angle pyramid mirror, directional inverse reflection of circular lens, and omnidirectional inverse reflection of cat-eye lens. The materials of the reflectors and bases used are metal, ceramic, plastic and composite materials. Due to the 360-degree spotlighting and reflecting effect, the cat-eye stud can provide reflecting function in all directions, which is a unique feature that other studs cannot have. In addition, since the cat-eye stud does not use plastic materials, but is composed of only glass body and metal coating reflection layer, both of which are environmentally friendly materials. Therefore, the research and development of cat-eye studs are increasingly valued. In order to test the quality of glass studs, we need to conduct pressure test on them, and apply pressure to extrude multiple glass studs. However, during the test process, unqualified glass studs will be crushed and splashed with fragments due to the small size of the fragments and the large impact force, which can easily cause accidents. Therefore, we need to improve it. SUMMARY

[0020] The pushing mechanism includes a fixed frame 5 fixedly arranged on the upper surface of the test table 2 and close to one side of the corresponding blank holder 4. A first air cylinder 7 is arranged in the middle of the fixed frame 5. The extension end of the first air cylinder 7 is connected with the outer wall of the protective shell 3. Two guide rods 6 are slidingly arranged at both ends of the fixed frame 5. Both ends of the two guide rods 6 are provided with fixed plates 13.

A flexible wiper blade 21 is arranged on the inner side of both the first mounting rod 22 and the second mounting rod 25. An arc-shaped clamping block 27 is arranged on the end of the second mounting rod 25 away from the spring 24. A plurality of rolling balls 26 are arranged in the clamping block 27. When the clamping block 27 at the front end of the first mounting rod 22 moves to the arc-shaped table 18, the rolling balls 26 will be extruded by the outer wall of the arc-shaped table 18 when the push block 30 moves. The rolling balls 26 roll and push the spring 24 in the sliding shell 23 to the rear end, so that the first mounting rod 22 can be flexibly retracted when passing through the arc-shaped table 18, and the debris near the arc-shaped table 18 can be easily cleaned. When the first mounting rod 22 and the second mounting rod 25 move to the middle part and then perform secondary scraping, the electric telescopic rod 29 can flexibly control the height to avoid bringing back the debris when cleaning back.

[0023] It is emphasized that the sliding connection of the first mounting rod 22 and the sliding shell 23 is dovetail sliding mode, when the spring 24 is extruded, the first mounting shell 22 will not deviate out of the outside of the sliding shell 23.

[0024] The U-shaped rod 33 is provided with a support block 34 at both ends of one side, and the upper surface of the support block 34 is provided with a liquid storage spraying device 37, and the inside of the liquid storage spraying device 37 is connected with a horizontal pipe 32 through a telescopic hose, and the outer part of the horizontal pipe 32 is fixedly installed on the outer edge of the push block 30 through a U-shaped clamp 35, and the inside of the horizontal pipe 32 is communicated and installed with a spray head 36, and the horizontal pipe 32 is stretched with the movement of the push block 30, and at this time the liquid storage spraying device 37 transports water to the horizontal pipe 32 through the telescopic hose, and then sprays out through the spray head 36, that is, the pressure environment in rainy days can be simulated inside the protective shell 3. It needs to be specially pointed out that the liquid storage spraying device 37 is composed of a liquid storage bottle and a small water pump.

[0025] The inside of the protective shell 3 is provided with a material falling shell 17, and the lower part of the inside of the material falling shell 17 is slidably installed with a pull plate 20, and when the material falling shell 17 moves to the material falling frame 4, the pull plate 20 can be pulled out to discharge the debris in the material falling shell 17, and the upper edge of the protective shell 3 is installed with a sinking type protective soft pad 14, and the protective soft pad 14 can protect above the protective shell 3, and avoid that part of the debris falls out from the open upper part.

[0026] Working principle: in use, the first air cylinder 7 on both sides of the test bench 2 moves the protective shell 3 to each other, so that the protective shell 3 is assembled into a full-enclosed protective structure, and then the glass nail to be subjected to pressure test is placed on the upper surface of the arc-shaped table 18, the controller 11 drives the hydraulic cylinder 10 to move downward, so that the pressure sensing head 12 extrudes the glass nail, and through continuous and continuous pressure, the compressive strength of the glass nail is tested. When the squeezed glass spike is critically broken, the fragments are blocked by the protective shell 3 and fall to the bottom of the protective shell 3. Since the two sides of the bottom of the protective shell 3 are provided with inclined surfaces 19, the fragments will be guided to the inner middle part. Some irregular fragments that are retained at the bottom of the protective shell 3 and cannot roll down to the inside of the blanking shell 17 are brought into the blanking shell 17 by the coordinated cooperation of the electric telescopic rod 29 and the second cylinder 28. During the process of downward pressure and transverse movement, the flexible scrapers 21 at the lower ends of the first mounting rod 22 and the second mounting rod 25 are prompted to bring the fragments into the blanking shell 17. The clamping block 27 and the ball 26 provided at the front end of the first mounting rod 22 can roll in contact with the curved platform 18 when they move to the curved platform 18, and in this case Under the condition of squeezing the spring 24 inside the sliding shell 23, the first mounting rod 22 can be well contracted, so that the area abutting the curved platform 18 can be cleaned in all directions. During the squeezing and pressurizing process, the liquid storage spraying device 37 sprays water in the squeezing environment, thereby simulating the pressure environment of the glass road studs on rainy days, thereby ensuring the authenticity of the pressure results. After the test is completed, the pressure sensing head 12 is lifted upward from the inside of the protective shell 3. At this time, the electric telescopic rod 29 can lift the U-shaped rod 33. The first mounting rod 22 slides to the front end when there is no pressure. The flexible scraper 21 at the lower end of the first mounting rod 22 can clean the debris on the upper surface of the curved platform 18. Finally, driven by the first cylinder 7, the protective shells 3 are driven away from each other until they move to the blanking rack 4, and the pull plate 20 inside the blanking shell 17 is manually opened, and the fragments fall to the inclined blanking rack 4 and are then discharged outside the test bench 2.
