Description

Technical Field

[0001] This utility model relates to the field of fuel tank installation technology, and in particular to a fuel tank installation reinforcement longitudinal beam. Background Technology

[0002] The fuel tank bracket should be installed on a sturdy part of the vehicle chassis, typically on the crossbeams or longitudinal beams of the frame. Before installation, the mounting area needs to be cleaned and rust-free to ensure the bracket attaches firmly. The choice of fixing method also affects safety. Common fixing methods include bolting and welding. When bolting, high-strength bolts should be selected and tightened to the specified torque. Welding requires a professional welder to ensure a uniform and strong weld. Furthermore, installation accuracy is crucial. The installation angle and position of the fuel tank bracket must be precise to avoid unnecessary stress on the fuel tank.

[0003] In the chassis systems of commercial vehicles and construction machinery, fuel tanks are typically secured using specialized mounting beams. Currently, common fixing methods often employ U-bolt clamps or a structure combining pressure plates and standard bolts. This type of structure has significant shortcomings in practical applications: First, during long-term vehicle operation, especially under harsh road conditions, the chassis experiences continuous and severe vibrations. These vibrations can easily cause the mounting bolts to loosen or even fall off, posing a significant safety hazard. Although standard anti-loosening components such as spring washers are often used, their effectiveness is limited, requiring frequent maintenance and tightening, increasing operating costs. Second, existing fuel tank longitudinal beams are mostly rigidly connected to the fuel tank, lacking effective buffering and vibration damping mechanisms. Road impacts and engine vibrations are transmitted to the fuel tank body with almost no attenuation, not only easily generating operating noise but also potentially causing fatigue cracking of the fuel tank welds and damage to the protective layer on the tank surface, severely affecting the service life of the fuel tank and driving safety. Therefore, there is a need in this field for a new type of fuel tank mounting reinforcement longitudinal beam that must have a more reliable anti-loosening mechanism to cope with strong vibrations, while also having an efficient buffering function to protect the fuel tank and improve the overall security and durability of the fixation. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, this utility model provides a longitudinal beam for reinforcing oil tank installation.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a fuel tank mounting reinforcement longitudinal beam, including two longitudinal beams and two crossbeams for fixing the two longitudinal beams. The inner side of the longitudinal beams is movably connected to a C-shaped connecting plate. The C-shaped connecting plate is provided with a buffer mechanism inside. The outer side of the C-shaped connecting plate is provided with a bolt reinforcement mechanism. The C-shaped connecting plate is connected to the fuel tank through the bolt reinforcement mechanism.

[0006] The bolt reinforcement mechanism includes a right-angle connecting plate. One side of the right-angle connecting plate is welded to the outer wall of the oil tank. A reinforcing rib is welded between the two sides of the right-angle connecting plate. A bolt is installed on the other side of the right-angle connecting plate. One end of the bolt extends into the interior of the C-shaped connecting plate. A flat washer is movably provided on the surface of the bolt. A nut is threaded to the other end of the bolt.

[0007] Furthermore, the bolt, nut, and flat washer constitute a set of fasteners, and the number of fasteners is not less than two sets. The nut has multiple through holes inside.

[0008] Furthermore, a steel wire rope is inserted inside the through hole for connecting and locking adjacent nuts in series, and both ends of the steel wire rope are fixedly connected with fastening buckles.

[0009] Furthermore, the buffer mechanism includes two sets of vertical buffer components and one set of horizontal buffer components. The vertical buffer components include an upper fixed seat and a lower fixed seat. The top surface of the upper fixed seat is fixedly connected to the inner top surface of the C-shaped connecting plate, and the bottom surface of the lower fixed seat is fixedly connected to the bottom of one side of the longitudinal beam. A guide telescopic rod is fixedly connected between the upper fixed seat and the lower fixed seat, and a first spring is sleeved on the surface of the guide telescopic rod.

[0010] Furthermore, the horizontal buffer assembly includes a connecting rod and a sliding rod. The top end of the connecting rod is rotatably connected to one side of the upper fixed seat, and the two ends of the sliding rod are respectively fixedly connected to the sides of the two lower fixed seats. A slider and a second spring are slidably sleeved on the surface of the sliding rod. The bottom end of the connecting rod is rotatably connected to the top of the slider, and one end of the slider and the second spring are fixedly connected.

[0011] Furthermore, a sliding pin is fixedly connected to the outer side of the C-shaped connecting plate away from the bolt reinforcement mechanism, and a sliding groove is provided on the surface of the longitudinal beam, with the surface of the sliding pin slidably connected to the inside of the sliding groove.

[0012] The beneficial effects of this utility model are that, through the combination of a bolt reinforcement mechanism, a right-angle connecting plate, reinforcing ribs, bolts, nuts, flat washers, through holes, wire ropes, and fastening buckles, the oil tank is placed between two C-shaped connecting plates during installation. The C-shaped connecting plates and the right-angle connecting plates are then locked together using bolts, nuts, and flat washers.

[0020] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0021] Example 1

[0022] according to Figure 1-5 As shown, a fuel tank mounting reinforcement longitudinal beam includes two longitudinal beams 1 and two crossbeams 2 for fixing the two longitudinal beams 1. A C-shaped connecting plate 4 is movably connected to the inner side of the longitudinal beams 1. A buffer mechanism 14 is provided inside the C-shaped connecting plate 4, and a bolt reinforcement mechanism 5 is provided on the outer side of the C-shaped connecting plate 4. The C-shaped connecting plate 4 is connected to the fuel tank 3 via the bolt reinforcement mechanism 5. The bolt reinforcement mechanism 5 includes a right-angle connecting plate 6. Any one surface of the right-angle connecting plate 6 is welded to the outer wall of the fuel tank 3, and the two surfaces of the right-angle connecting plate 6 are welded together. A bolt 8 is installed on the other side of the right-angle connecting plate 6, which is connected to a reinforcing rib 7. One end of the bolt 8 extends into the interior of the C-shaped connecting plate 4. A flat washer 10 is movably provided on the surface of the bolt 8. A nut 9 is threadedly connected to the other end of the bolt 8. The bolt 8, nut 9 and flat washer 10 are a set of fasteners. There are no less than two sets of fasteners. The nut 9 has multiple through holes 11 inside. A steel wire rope 12 is inserted inside the through holes 11 and can be used to lock adjacent nuts 9 in series. Both ends of the steel wire rope 12 are fixedly connected with fastening buckles 13.

[0023] In this embodiment, when installing the oil tank 3, the oil tank 3 is placed between two C-shaped connecting plates 4, and the C-shaped connecting plates 4 and the right-angle connecting plates 6 are locked together with bolts 8, nuts 9 and flat washers 10. Then, the wire rope 12 is threaded into the through hole 11. The nuts are usually tightened in a clockwise direction, so when threading the wire rope 12, the principle of "pulling the middle of the wire rope 12 can make the adjacent nuts 9 rotate in the tightening direction" should be followed. In this way, if any one nut 9 loosens later, it will drive the other nut 9 to tighten more, thus forming a balance. This ensures that the two bound nuts can only loosen within a limited range without affecting the overall use. After the wire rope 12 is threaded, it can be tightened with the fastening buckle 13. This device upgrades the traditional bolt reinforcement method with a simple structure and low cost, improving the reliability of the threaded connection.

[0024] Example 2

[0025] according to Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the buffer mechanism 14 includes two sets of vertical buffer components 15 and one set of horizontal buffer components 20. The vertical buffer component 15 includes an upper fixed seat 16 and a lower fixed seat 17. The top surface of the upper fixed seat 16 is fixedly connected to the inner top surface of the C-shaped connecting plate 4, and the bottom surface of the lower fixed seat 17 is fixedly connected to the bottom of one side of the longitudinal beam 1. A guide telescopic rod 18 is fixedly connected between the upper fixed seat 16 and the lower fixed seat 17. A first spring 19 is sleeved on the surface of the guide telescopic rod 18. The horizontal buffer component... 20 includes a connecting rod 21 and a sliding rod 22. The top end of the connecting rod 21 is rotatably connected to one side of the upper fixed seat 16. The two ends of the sliding rod 22 are respectively fixedly connected to the sides of the two lower fixed seats 17. The surface of the sliding rod 22 is slidably sleeved with a slider 23 and a second spring 24. The bottom end of the connecting rod 21 is rotatably connected to the top of the slider 23. One end of the slider 23 and the second spring 24 are fixedly connected. The outer side of the C-shaped connecting plate 4 away from the bolt reinforcement mechanism 5 is fixedly connected with a sliding pin 25. The surface of the longitudinal beam 1 is provided with a sliding groove, and the surface of the sliding pin 25 is slidably connected to the inside of the sliding groove.

[0026] In this embodiment, after the fuel tank 3 is installed on the C-shaped connecting plate 4, the vehicle often vibrates during use. The two sets of first springs 19 can absorb the impact force when the fuel tank 3 moves up and down. The connecting rod 21 and the slider 23 can disperse part of the vertical impact force to the horizontal direction and be absorbed by the second spring 24, which further improves the buffering effect. The guide telescopic rod 18 and the sliding pin 25 limit the horizontal displacement of the fuel tank 3 and improve the stability of the device.

[0027] The working principle of the reinforcing longitudinal beam for the fuel tank will be explained in detail below.

[0028] according to Figure 1-5As shown, in use, the oil tank 3 is first installed and placed between two C-shaped connecting plates 4. The C-shaped connecting plates 4 and the right-angle connecting plate 6 are then locked together using bolts 8, nuts 9, and flat washers 10. Next, the steel wire rope 12 is threaded into the through hole 11. The nuts are typically tightened clockwise, so when threading the steel wire rope 12, the principle should be followed: "Pulling the middle of the steel wire rope 12 will cause adjacent nuts 9 to rotate in the tightening direction." This ensures that if any one nut 9 loosens later, it will cause the other nut 9 to tighten further, creating a balance. This ensures that the two bound nuts can only loosen within a limited range without affecting the overall use. After the wire rope 12 is threaded, it can be tightened by the fastening buckle 13. This device upgrades the traditional bolt reinforcement method with a simple structure and low cost, improving the reliability of the threaded connection. After the oil tank 3 is installed on the C-shaped connecting plate 4, the vehicle often vibrates during use. The impact force when the oil tank 3 moves up and down can be absorbed by the two sets of first springs 19. The vertical impact force can be dispersed to the horizontal direction by the connecting rod 21 and the slider 23 and absorbed by the second spring 24, further improving the buffering effect. The horizontal displacement of the oil tank 3 is limited by the guide telescopic rod 18 and the sliding pin 25, which improves the stability of the device.

[0029] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
