[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a hazardous chemical transport vehicle anti-rollover warning device, including: a fixed frame 1, a movable cylinder 5, a support rod 20, and a tilt sensor 28. The tilt sensor 28 is fixedly installed on the lower outer side of the vehicle body 27 of the hazardous chemical transport vehicle to detect whether the hazardous chemical transport vehicle is tilting. The movable cylinder 5 is slidably disposed in the fixed frame 1. The inner walls of the front and rear sides of the outer end of the fixed frame 1 are provided with a sliding groove 4. The outer walls of the front and rear ends of the movable cylinder 5 are fixedly installed with a slider 7. The inner walls of the front and rear ends of the movable cylinder 5 are provided with a sliding groove 8. The slider 7 slides into the sliding groove 4. When the movable cylinder 5 moves in the fixed frame 1, the slider 7 slides in the sliding groove 4 to guide and limit the movable cylinder 5.

[0024] The support rod 20 is movably set inside the movable cylinder 5. The outer end of the movable cylinder 5 is provided with a clearance groove 10. The movable block 14 is slidably connected inside the movable cylinder 5. Slider 2 17 is fixedly installed on the outer wall of the front and rear ends of the movable block 14. Rubber pads 18 are fixedly installed on the upper and lower ends of slider 2 17. Slider 2 17 is slidably inserted into slide groove 2 8. Rubber pad 18 contacts the inner wall of slide groove 2 8. Rubber pad 18 increases the friction between slider 2 17 and slide groove 2 8, making the friction between slider 2 17 and slide groove 2 8 greater than the friction between slider 1 7 and slide groove 1 4.

[0025] The outer end of the movable block 14 is rotatably connected to the upper end of the support rod 20 via the fixing plate 19. The fixing plate 19 is fixedly installed on the front and rear sides of the outer end of the movable block 14. The upper end of the support rod 20 is inserted between the two fixing plates 19 and is rotatably connected via a rotating shaft. The lower end of the support rod 20 is rotatably connected to the shaft 21. The outer end of the shaft 21 is fixedly connected to the roller 22. The support rod 20 can rotate on one side of the movable block 14 with the roller 22.

[0026] A rear baffle 2 is fixedly installed at one end of the fixed frame 1. An electric push rod 3 is installed inside the fixed frame 1. One end of the electric push rod 3 is fixed to the rear baffle 2. The output end of the electric push rod 3 is fixedly connected to the inner end of the moving block 14. When the electric push rod 3 drives the moving block 14 to move, the friction between the second slider 17 and the second groove 8 is greater than the friction between the first slider 7 and the first groove 4. The moving cylinder 5 moves inside the fixed frame 1. When the moving cylinder 5 moves to the outermost position, the moving block 14 slides inside the moving cylinder 5, thereby driving the support rod 20 to the outside until the moving block 14 moves to one side of the clearance groove 10. The support rod 20 falls vertically into the clearance groove 10 under the gravity of the roller 22. At this time, the roller 22 is located on the lower side of the outer end of the transport vehicle platform 27. When the hazardous chemical transport vehicle overturns, the roller 22 contacts the ground, which forcibly stops the overturning tendency of the vehicle.

[0027] A limiting component is installed on the outer upper end of the movable cylinder 5. The limiting component includes a strip hole 6, a limiting groove 9, a vertical plate 15, and a limiting plate 11. The strip hole 6 is located at the upper end of the movable cylinder 5. The vertical plate 15 is L-shaped, and its lower end is fixed to the upper end of the movable block 14. The upper end of the vertical plate 15 passes through the strip hole 6 and is fixedly installed with a drive plate 16. The drive plate 16 moves synchronously with the movable block 14. The limiting groove 9 is fixedly installed on the side walls of the front and rear sides of the outer end of the movable cylinder 5. The upper end of the limiting plate 11 has a ramp, and its lower end slides between the two limiting grooves 9. Ear plates 12 are fixedly installed on the outer walls of both the front and rear ends of 11. A spring 13 is fixedly installed on the lower end of the ear plate 12. The lower end of the spring 13 is fixed to the upper end of the limiting groove 9. When the spring 13 is in a balanced state, the lower end of the limiting plate 11 is flush with the upper side wall of the moving cylinder 5, which will not affect the movement of the support rod 20 in the moving cylinder 5. When the support rod 20 falls into the relief groove 10, the drive plate 16 presses down the limiting plate 11 through the ramp. The limiting plate 11 moves down to the outer end of the support rod 20 by squeezing the spring 13, thereby fixing the support rod 20 in the relief groove 10.

[0028] The fixed frame 1 is installed at the lower end of the transport vehicle platform 27 by a fixing component. The tilt sensor 28 is fixed to the lower side of the outer end of the transport vehicle platform 27. The fixing component includes a support plate 23. The lower end of the support plate 23 has a sleeve groove 24, which is sleeved on the outer end of the fixed frame 1. The lower end of the support plate 23 is fixedly connected to a base plate 25 by bolts. The base plate 25 is located at the lower end of the fixed frame 1. Bolts are welded to the lower end of the support plate 23. The bolts pass through the base plate 25 and are threaded with nuts, thereby fixing the base plate 25 to the lower end of the fixed frame 1. A fixing groove 26 is fixedly installed at the upper end of the support plate 23. The fixing groove 26 is U-shaped and sleeved on the outer side of the crossbeam at the lower end of the transport vehicle platform 27. It is fixedly connected by bolts, thus fixing the device to the lower end of the dangerous goods transport vehicle platform 27.

[0029] When the device is not in use, the electric push rod 3 reinforces the moving cylinder 5 and retracts it into the fixed frame 1. The support rod 20 is located inside the moving cylinder 5, and the roller 22 is located between the vehicle chassis and the fixed frame 1. One side of the roller 22 is located at the upper end of the limiting plate 11, and the device is stored at the lower end of the vehicle chassis.

[0030] Warning lights are installed on the outside of the cargo compartment and in the driver's cab of the dangerous goods transport vehicle. A controller is also fixedly installed in the driver's cab. The controller is electrically connected to the warning lights, tilt sensor 28 and electric push rod 3.

[0031] In use: When a hazardous materials transport vehicle overturns during operation, the tilt sensor 28 immediately sends a signal to the controller. The controller then controls the warning lights to flash continuously to alert the driver and vehicles behind. At the same time, the controller controls the electric push rod 3 to start quickly. The electric push rod 3 pushes the moving cylinder 5 and the support rod 20 to the outside of the vehicle. When the hazardous materials transport vehicle overturns, the rollers 22 come into contact with the ground, thus forcibly stopping the vehicle's overturning tendency.

[0032] 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.
