Description

Technical Field

[0001] This utility model relates to the field of vehicle protection equipment technology, and more specifically, to an EGP front protection structure for hazardous chemical transport vehicles. Background Technology

[0002] In the field of hazardous chemical transportation, ensuring the safety and efficiency of transport vehicles is paramount. This is especially true for critical vehicle components, such as the EGP (Electronic Gas Controller Plate, China IV emission standard), also commonly referred to as a catalytic converter-equipped muffler. This is a crucial part of the vehicle's exhaust treatment system, used to reduce pollutants emitted by diesel engines. The exhaust gas processor is equipped with catalytic converter temperature sensors and NOx sensors to monitor and control key parameters during the exhaust treatment process. The design and installation of its protective structure directly affect the overall performance and safety of the vehicle.

[0003] Traditional EGP (Extreme Protection Plate) structures for hazardous materials transport vehicles often employ a fixed design, meaning the position and angle of the protective plates remain unchanged after installation. While this design offers some protection against external impacts, it has several drawbacks. For example, because the angle and position of the protective plates cannot be adjusted according to different driving conditions and road conditions, fixed protective plates may generate significant wind resistance during operation, thereby increasing fuel consumption and operating costs.

[0017] 3. Beneficial effects

[0018] Compared with existing technologies, this utility model provides an EGP front protective structure for hazardous chemical transport vehicles, which has the following advantages:

[0019] This EGP (Electronic Gas Protection) front protection structure for hazardous chemical transport vehicles uses a synchronous drive assembly to control the synchronous rotation of two transmission threaded rods.

Furthermore, the optimized angle reduces wind resistance, decreases fuel consumption, and improves fuel economy. Attached Figure Description

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.

[0028] Example:

[0029] Please see Figures 1-5 An EGP front protective structure for hazardous materials transport vehicles, comprising:

[0030] Two mounting boxes 1, each mounting box 1 has a transmission threaded rod 8 rotatably connected between the inner walls on both sides, and a transmission block 7 slidably passes through the inner bottom wall of each mounting box 1. The two transmission blocks 7 are threadedly connected to the two transmission threaded rods 8 respectively. The bottom of the two transmission blocks 7 is fixedly connected to a support frame 2, and a protective plate 3 is rotatably connected between the inner walls on both sides of the support frame 2.

[0031] Synchronization drive components are installed on both mounting boxes 1; and

[0032] Steering control box 4 is fixedly connected to one side of the outer surface of support frame 2. A transmission worm gear 10 is rotatably connected between the two inner walls of steering control box 4. A transmission worm wheel 11 is rotatably connected between the front and rear inner walls of steering control box 4. The transmission worm wheel 11 is meshed with the transmission worm gear 10, and the transmission worm wheel 11 is fixedly connected to the protective plate 3 through a rotating shaft.

[0033] In a specific embodiment of this utility model, the synchronous control box 5 and two mounting boxes 1 are used to install at the bottom of the hazardous chemical transport vehicle. The protective plate 3 is located on the front side of the EGP. The synchronous drive assembly can control the two transmission threaded rods 8 to rotate synchronously. The two transmission threaded rods 8 drive the two transmission blocks 7 to move synchronously, thereby driving the support frame 2 to move, thus adjusting the distance between the protective plate 3 and the EGP. At the same time, by controlling the rotation of the transmission worm gear 10, the transmission worm wheel 11 is driven to rotate at a certain angle, thereby adjusting the angle of the protective plate 3. By adjusting the angle and position of the protective plate 3, the protective plate 3 can adapt to various installation environments and effectively protect the EGP from external impacts and damage while being as close to the EGP as possible. At the same time, the angle is optimized to reduce wind resistance, reduce fuel consumption, and improve fuel economy.

[0034] Specifically, the synchronous drive assembly includes a synchronous control box 5 and two synchronous pulleys. The synchronous control box 5 is fixedly connected to the outer surface of one side of the two mounting boxes 1. The two synchronous pulleys are rotatably connected between the inner walls of the two sides of the synchronous control box 5. The two synchronous pulleys are fixedly connected to the two transmission threaded rods 8 respectively.

[0035] In this embodiment, the two synchronous pulleys are connected by a synchronous belt drive, so that the two transmission threaded rods 8 keep rotating synchronously.

[0036] Specifically, the synchronous drive assembly also includes a drive motor 6, which is fixedly connected to one side of the outer surface of the synchronous control box 5, and the output end of the drive motor 6 is fixedly connected to one of the synchronous pulleys.

[0037] In this embodiment, by controlling the start of the drive motor 6, the corresponding synchronous wheel can be driven to rotate.

[0038] Specifically, each mounting box 1 has a limit rod 9 fixedly connected between the inner walls on both sides, and each transmission block 7 is slidably sleeved on the corresponding limit rod 9.

[0039] In this embodiment, each limiting rod 9 ensures that the corresponding transmission block 7 remains stable during movement.

[0040] Specifically, both limit rods 9 are made of stainless steel.

[0041] In this embodiment, the surface of the limiting rod 9 is smooth, and it is strong and durable.

[0042] Specifically, a servo motor 12 is fixedly installed on one outer surface of the steering control box 4, and the output end of the servo motor 12 is fixedly connected to the transmission worm gear 10.

[0043] In this embodiment, by controlling the servo motor 12 to start, the transmission worm gear 10 can be driven to rotate.

[0044] Working Principle: After the synchronous control box 5 and two mounting boxes 1 are installed at the bottom of the hazardous chemical transport vehicle, the protective plate 3 is located in front of the EGP. By controlling the start of the drive motor 6, the two synchronous wheels rotate synchronously, thereby controlling the synchronous rotation of the two transmission threaded rods 8. The two transmission threaded rods 8 drive the two transmission blocks 7 to move synchronously, thereby moving the support frame 2 and adjusting the distance between the protective plate 3 and the EGP. At the same time, by controlling the start of the servo motor 12, the transmission worm gear 10 rotates, which in turn drives the transmission worm wheel 11 to rotate at a certain angle, thereby adjusting the angle of the protective plate 3. By adjusting the angle and position of the protective plate 3, the protective plate 3 can adapt to various installation environments and effectively protect the EGP from external impacts and damage while being as close to the EGP as possible. At the same time, the angle is optimized to reduce wind resistance, reduce fuel consumption, and improve fuel economy. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power components and the power supply are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0045] 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 its improved concept should be covered within the protection scope of the present utility model.
