Description

Technical Field

[0001] This utility model relates to the field of tank truck technology, specifically a protective structure for a dangerous goods tank truck. Background Technology

[0002] Dangerous goods transport vehicles are special vehicles with an open cargo box, a front-mounted exhaust pipe equipped with a spark arrestor, and used to transport dangerous goods such as petrochemicals, explosives, and fireworks.

[0003] Traditional adhesive installation of reflective strips on hazardous materials transport vehicles requires complete removal of the old adhesive during replacement, which is time-consuming and can easily damage the surface of the vehicle's protective structure. Furthermore, adhesive installation makes it difficult to ensure a tight fit between the reflective strip and the vehicle body, which can easily lead to air bubbles or wrinkles and reduce reflectivity. To address these issues, we have proposed a protective structure for hazardous materials transport tank trucks. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4A protective structure for a dangerous goods transport tanker includes: a rear protective beam, which is an integrally formed anti-collision beam 1 and a support column 2. The integral forming eliminates the stress concentration problem of traditional welding and improves the overall strength and fatigue life of the structure; a reinforcing beam 3 is provided between the support column 2 and the anti-collision beam 1. The two ends of the reinforcing beam 3 are welded to the anti-collision beam 1 and the support column 2 respectively. The reinforcing beam 3 forms a double reinforcement structure, optimizes the collision energy transmission path, and enhances the torsional resistance and deformation resistance. The ends of the support column 2 are also welded with square flanges 4 for connecting with the transport tanker. The square flanges 4 can increase the contact area, improve the connection stability, reduce local stress concentration, and improve the connection reliability and durability.

[0021] A reflective strip 5 is positioned on the front of the anti-collision beam 1. A connecting mechanism 6 is positioned between the reflective strip 5 and the anti-collision beam 1. The connecting mechanism 6 includes a card box 61 that can engage with the reflective strip 5. A first screw 66 is threaded onto the inner wall of the card box 61, and the first screw 66 can also be threaded onto the anti-collision beam 1. A circular hole is also provided on the inner wall of the card box 61 to accommodate the nut of the first screw 66. A washer 65 is provided inside the circular hole, and the washer 65 contacts both the nut of the first screw 66 and the card box 61. A guide rail 64 is fixedly installed on the side of the card box 61, and a frame strip 62 is also engaged at the opening of the card box 61. A boss 63 is fixedly installed on the side of the frame strip 62, and a round shaft 67 is fixedly installed inside the boss 63. The round shaft 67 can slide with the guide rail 64. The cooperation between the guide rail 64 and the round shaft 67 ensures that the frame strip 62 is precisely aligned with the notch of the card box 61 after rotation. To ensure accurate installation of the reflective strip 5, a clip 68 is fixedly installed on the front of the frame strip 62. The internal thread of the clip 68 is connected to a second screw 69, which is also threaded into the cartridge 61. The frame strip 62 slides and rotates along the guide rail 64 via a round shaft 67, enabling quick removal and installation of the reflective strip 5. During maintenance, after loosening the second screw 69, the frame strip 62 can rotate at a large angle, facilitating the replacement of the reflective strip 5. The clip 68 has an L-shaped structure design, and after the frame strip 62 is inserted into the cartridge 61, the threaded hole on the side of the clip 68 for engaging the second screw 69 coincides with the threaded hole on the side of the cartridge 61 for engaging the second screw 69. The reflective strip 5 includes a reflective surface and an outwardly expanding edge. The frame strip 62 contacts the outwardly expanding edge of the reflective strip 5. The outwardly expanding edge of the reflective strip 5 increases the contact area between the reflective surface and the frame strip 62, preventing the edge from lifting, ensuring the flatness of the reflective surface, and improving the reflective effect.

[0022] Working principle: The anti-collision beam 1 and the support column 2 are integrally formed. The square flange 4 at the end of the support column 2 is installed at the rear of the vehicle. A reinforcing beam 3 is also provided at the connection between the anti-collision beam 1 and the support column 2 to enhance the overall protective strength. Simultaneously, a reflective strip 5 is engaged with the surface of the anti-collision beam 1 via a connecting mechanism 6 to improve the visibility of the entire protective structure at night. When maintenance of the reflective strip 5 is required, the second screw 69 is loosened, releasing the connection between the clip 68 and the card holder 61. The frame strip 62, integrally formed with the clip 68, can then slide along the guide rail 64 on the card holder 61 via the round shaft 67 on the side of the protrusion 63 on the other side of the frame strip 62 until the round shaft 67 reaches the end of the guide rail 64. At this point, the entire frame strip 62 is... The reflector strip 5 can be removed for maintenance by rotating the circular shaft 67 as the center. After the new reflector strip 5 is re-inserted into the card box 61 on the front of the anti-collision beam 1, the frame strip 62 is rotated so that it aligns with the notch in the card box 61. The frame strip 62 is then pushed into the card box 61 to press down the boundary of the reflector strip 5. At this time, the threaded hole of the clip 68 is aligned with the threaded hole on the side of the card box 61. The second screw 69 is tightened, and the reflector strip 5 can be fixed inside the card box 61 by using the frame strip 62. At the same time, the card box 61 and the anti-collision beam 1 are installed by the first screw 66. A washer 65 is also added at the connection between the first screw 66 and the card box 61 to increase the contact area between the first screw 66 nut and the card box 61.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
