Description

Technical Field

[0001] The utility model relates to the technical field of loader fuel tanks, in particular to a fuel tank leakage prevention device for a low-emission loader. Background Art

[0002] The fuel tank anti-leakage device of a low-emission loader is usually a sealing cover or gasket made of special materials, which is used to ensure that the fuel tank does not leak in the event of a collision or other unexpected situations, thereby reducing environmental pollution and fire risks.

[0003] A Chinese patent with announcement number CN217598343U discloses a fuel tank anti-leakage device for a low-emission loader. The slide groove of the fuel tank protective cover is inserted into the trapezoidal slide rail, and a limit bolt is installed after installation. The limit bolt can prevent the loader from shaking off the fuel tank protective cover during driving, so that the loader fuel tank body can be safely protected by the protection mechanism; however, the existing device is difficult to disassemble and replace the protective side panel during use, which increases maintenance costs, prolongs maintenance time, and reduces equipment availability and production efficiency. At the same time, if the protective side panel needs to be replaced but cannot be disassembled in time, the anti-leakage function of the fuel tank may be damaged, increasing the risk of accidental leakage and affecting the environment and personnel safety.

[0026] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0027] Embodiment 1:

[0028] See also Figure 1 A fuel tank anti-leakage device for a low-emission loader includes: a box body 1, a damper 4 is fixed to the outer wall of the box body 1, one end of the damper 4 is connected to a protective side plate 5, and a shock-absorbing spring sleeved on the outer wall of the damper 4 is connected to the box body 1 and the protective side plate 5.

[0029] When in use, the box 1 is installed on the low-emission loader. Through the setting of the protective side plate 5, when the box 1 is hit, the shock-absorbing spring is driven to contract, and the damper 4 is driven to start working through the contraction of the shock-absorbing spring. After the collision, the damper 4 is driven to reset through the elastic force of the shock-absorbing spring, thereby driving the protective side plate 5 to reset synchronously, so that the harm caused by the collision can be easily resolved, and at the same time, the protection of the box 1 is increased to avoid leakage.

[0030] Embodiment 2:

[0031] See also Figure 1 - Figure 4, disassembly mechanism 2, the disassembly mechanism 2 is located between the damper 4 and the protective side plate 5, and the disassembly mechanism 2 is used to quickly separate the protective side plate 5 from the damper 4, the disassembly mechanism 2 includes a positioning mechanism, a reset mechanism and a driving mechanism, the reset mechanism is connected to the driving mechanism, and the reset mechanism and the driving mechanism are located inside the positioning mechanism, the positioning mechanism includes a mounting groove opened on one side of the protective side plate 5 and a disassembly plate 21 fixed at one end of the damper 4, the disassembly plate 21 corresponds to the mounting groove, and a positioning rod 26 is installed inside the protective side plate 5 ... A positioning groove for the positioning rod 26 to be inserted is provided inside the unloading plate 21. The driving mechanism includes a storage groove provided inside the protective side plate 5 and a movable plate 25 installed inside the storage groove. The movable plate 25 is fixed to the positioning rod 26. The reset mechanism includes two movable rods 23 fixed on one side of the movable plate 25 and two reset springs 24 connected between the movable plate 25 and the storage groove. The two reset springs 24 are both sleeved on the outer walls of the two movable rods 23. The two movable rods 23 extend to one side of the protective side plate 5 and are commonly fixed with a control plate 22.

[0032] When in use, first pull the control plate 22 to drive the movable rod 23 to move, and the movement of the movable rod 23 drives the movable plate 25 to move in the storage groove, and the movement of the movable plate 25 drives the return spring 24 to contract. The contraction of the return spring 24 makes the movable plate 25 drive the positioning rod 26 to move, and the positioning rod 26 is moved to separate it from the positioning groove. The mutual separation of the positioning rod 26 and the positioning groove makes the disassembly plate 21 no longer positioned, and then the protective side plate 5 is moved to separate it from the disassembly plate 21, thereby completing the disassembly operation of the protective side plate 5, facilitating its maintenance and replacement, and avoiding the situation where the protective side plate 5 is damaged and difficult to replace in time, which greatly increases the protection of the box body 1 of the utility model and makes it safer when in use.

[0033] Embodiment 3:

[0034] See also Figure 1 and Figure 5 An oil inlet pipe is connected to the top of the box body 1, and a supporting mechanism 3 is arranged on the top of the box body 1. The supporting mechanism 3 includes a protective box 31 fixed to the top of the box body 1 and a door panel 32 hinged to the top of the protective box 31. The protective box 31 is installed on the outer wall of the oil inlet pipe, and a supporting frame 37 is arranged on one side of the protective box 31. A plurality of evenly distributed anti-sliding blocks are fixed to the top of the supporting frame 37, a linkage plate 36 is fixed to the bottom of the supporting frame 37, an internal thread plate 35 is fixed to one side of the linkage plate 36, and a threaded mechanism for driving the internal thread plate 35 to move up and down is arranged between the internal thread plate 35 and the protective box 31.

[0035] When in use, the door panel 32 is rotated to form an open state, and then the oil gun is aligned with the oil inlet pipe to perform an oil filling operation on the inside of the box body 1. The threaded rod 34 is then rotated to drive the internal threaded plate 35 to move on its outer wall. The movement of the internal threaded plate 35 drives the linkage plate 36 to move, and the movement of the linkage plate 36 drives the support frame 37 to move synchronously until the support frame 37 is moved to the position corresponding to the oil gun, so that the support frame 37 can support the oil gun to avoid the oil gun and the oil inlet pipe from colliding with each other and causing damage to the oil inlet pipe, thereby increasing the protection of the device to the oil inlet pipe.

[0036] Regarding the above-mentioned threaded mechanism, Figure 5 As shown, the thread mechanism includes a fixing plate 33 fixed to one side of the protection box 31 and a threaded rod 34 connected between the fixing plate 33 and the protection box 31 , and an internal threaded plate 35 is screwed to the outer wall of the threaded rod 34 .
