Abstract
Description
Technical Field
[0001] This utility model relates to a tank truck frame beam, specifically a tank truck frame beam with a reinforced structure that can prevent damage at stress concentration points. Background Technology
[0002] Currently, the main beams of liquid or powder tank semi-trailers are generally made of welded steel structures. The front of the main beam is the mounting section, which typically serves as the area for mounting diesel engines, pumps, air compressors, and other related accessories. During operation, the mounting section is subjected to dynamic impact loads from road bumps and other conditions, making it one of the most stress-concentrated parts of the vehicle structure.
[0003] In the existing frame beam structure, such as Figure 3 As shown, it includes an upper plate, a lower plate, and a central vertical web. The upper and lower plates are generally made of steel strip. An upward-extending bend is provided on the lower plate behind the mounting section to increase the height of the lower end of the frame from the ground, facilitating the connection of the frame to the tow bar. Existing frame beams are prone to stress concentration at their bends, making them susceptible to breakage due to bumps, heavy loads, and other factors. Utility Model Content
[0004] The main purpose of this utility model is to provide a chassis beam for tank trucks, which aims to solve the problem that the existing chassis beams for tank trucks are prone to breakage at the bending points of the mounting section due to bumps, heavy loads, and other reasons.
[0005] This utility model provides a tank truck frame beam, including an upper plate, a lower plate, and a central vertical web plate. The upper plate, the lower plate, and the web plate are welded together to form an I-beam. The tank truck frame beam includes a main beam body that supports the tank body. The main beam body extends forward to form a transition section, and the transition section extends forward to form a mounting section. The upper plate extends obliquely downward and forward from the rear end of the transition section. The web plate has an opening that extends horizontally backward from the upper front part of the transition section. The upper plate at the mounting section has a rearwardly extending middle plate that extends backward and inserts into the opening.
[0006] Preferably, a vertically arranged and laterally extended reinforcing plate is provided on the rear side of the transition portion, the upper end of the reinforcing plate is attached to the upper plate, the lower end of the reinforcing plate is attached to the lower plate, and the inner side of the reinforcing plate is attached to the web plate.
[0007] Preferably, the rear end of the medium plate abuts against the reinforcing plate.
[0008] Preferably, the chassis beam of the tanker truck is used on a liquid tanker truck, a diesel engine is installed on the mounting part, and a traction device is installed at the corresponding position of the mounting part.
[0009] Compared with the prior art, the tanker truck frame beam provided by this utility model has the following advantages:
[0010] The aforementioned tank truck frame beam features an upper flat plate that extends downwards and forwards at the rear end of the transition section, thereby lowering the height of the upper surface of the mounting section. This allows for the installation of diesel engines, pumps, air compressors, and other related accessories at a lower height, improving the convenience of accessory installation. Simultaneously, the mounting section connects to the main vehicle structure, such as the cab, and can better bear the weight of the accessories. Furthermore, in this invention, the web of the transition section has an opening extending horizontally backwards from the front end, and the upper flat plate of the mounting section extends into this opening to form a middle flat plate. By adding a middle flat plate, the strength of the transition section is improved. When shear stress is concentrated, the shear force can be distributed through the middle flat plate, preventing breakage at the transition section. Additionally, the central reinforcing structure formed by the opening and the middle flat plate results in a relatively simple manufacturing process and stable mechanical properties.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] Example 1
[0018] This embodiment provides a tank truck frame beam, which includes an upper plate 5, a lower plate 4, and a central vertical web 6. The upper plate 5, the lower plate 4, and the web 6 are welded together to form an I-beam. The frame beam and crossbeams together form the chassis. In this embodiment, the tank truck frame beam includes a main beam body 1 located at the rear for supporting the tank body. The main beam body 1 extends forward to form a transition section 2, and the transition section 2 extends forward to form a mounting section 3. The upper plate 5 extends obliquely downward and forward from the rear end of the transition section 2. The web 6 has an opening that extends horizontally backward from the upper front end of the transition section 2. The upper plate 5 at the mounting section 3 has a rearwardly extending middle plate 8 that extends backward and inserts into the opening.
[0019] In this embodiment, the tanker truck frame beam consists of a main beam 1, a transition section 2, and a mounting section 3 from back to front. The upper surface of the transition section 2 gradually decreases, thereby reducing the height of the upper surface of the mounting section 3. This allows the mounting section 3 to be installed at a lower height, facilitating the installation of related accessories such as the diesel engine 10, pump body, and air compressor, thus improving the ease of accessory installation. Simultaneously, the mounting section 3 is connected to the main vehicle structure, such as the cab, via a traction device or similar structure, enabling it to better bear the weight of the accessories. Finally, in this embodiment, the web plate 6 of the transition section 2 has an opening extending horizontally from the front to the rear. The upper plate 5 of the mounting section 3 extends horizontally forward and is inserted into this opening. This method adds a middle plate 8 to the middle of the web plate 6 of the transition section 2. Adding the middle plate 8 increases the strength of the transition section 2, and the middle plate 8 can distribute the shear force during shear stress concentration, preventing breakage at the transition section 2. Furthermore, the opening and the middle plate 8 form a central reinforcing structure, simplifying the manufacturing process and ensuring stable mechanical properties.
[0020] Specifically, in this embodiment, a vertically arranged and laterally extended reinforcing plate 9 is provided on the rear side of the transition part 2. The upper end of the reinforcing plate 9 is attached to the upper plate 5, the lower end of the reinforcing plate 9 is attached to the lower plate 4, and the inner side of the reinforcing plate 9 is attached to the web plate 6. That is, the reinforcing plate 9 is provided on at least one side of the web plate 6 and is perpendicular to the web plate 6. The reinforcing plate 9 is generally connected to the upper plate 5, the lower plate 4 and the web plate 6 by welding.
[0021] More specifically, in this embodiment, the rear end of the medium plate 8 abuts against the reinforcing plate 9, that is, the medium plate 8 and the reinforcing plate 9 are connected into a single structure by welding or any other means, which improves the strength of the transition part 2 and avoids damage at the stress concentration point.
[0022] More specifically, in this embodiment, the tanker frame beam is used on a liquid tanker, a diesel engine 10 is provided on the mounting part 3, and a traction device is provided at the corresponding position of the mounting part 3.
[0023] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
