Description

Technical Field

[0001] This utility model relates to the field of fuel tank technology, specifically to a fuel tank structure for a loader. Background Technology

[0002] 12-ton loaders are commonly used in heavy earthmoving projects, mines, and other places. They are often used for heavy-duty operations and have high operating efficiency, but also high fuel consumption. A fuel tank has been developed specifically for 12-ton large loaders. The effective volume of the fuel tank is about 650 liters, which can meet the normal working time of more than 10 hours.

[0003] Large loaders have a higher overall weight, and the frequent rapid acceleration and deceleration during operation result in greater external impact on the fuel tank. Moreover, to be suitable for large loaders, the fuel tank needs to have a larger volume and a height of over 1.5 meters. During vehicle operation, the impact of the fuel on the fuel tank is significant. As a result, for larger fuel tanks with higher pressure requirements, the impact of the fuel on the fuel tank is greater, which can easily lead to stress concentration problems at the mounting base, causing cracks in the welds or base material, making the fuel tank prone to damage. Utility Model Content

[0004] The purpose of this invention is to provide a fuel tank structure for loaders that can solve the technical problem of internal impact in existing fuel tanks.

[0005] To achieve the above objectives, this utility model proposes a fuel tank structure for a loader, including a lower cover plate and an upper cover plate. Several partitions are arranged at the bottom of the lower cover plate and along its length. The bottom of each partition plate has a serrated notch. Several mounting seats are fixedly arranged on the side wall of the lower cover plate by means of a mounting plate.

[0006] A further configuration is that the top of the upper cover is connected to the respirator via an oil pipe.

[0007] A further configuration is that a filter is connected above the respirator via an oil pipe.

[0008] A further configuration is provided whereby an oil return assembly and an oil suction assembly are provided on one side of the respirator and on top of the upper cover plate.

[0009] A further configuration is provided whereby a water tank trough is provided on one side of the respirator and at the top of the cover plate.

[0010] A further feature is provided that a cleaning flange is provided on the front side of the upper cover plate.

[0011] A further configuration includes an injection port installed on one side of the lower cover plate.

[0012] A further feature is that an oil receiving valve is installed on the filling port, and the oil receiving valve is detached and installed on one side of the filling port.

[0013] A further feature is provided: an oil drain plug is installed at the bottom of the lower cover plate.

[0014] Further configuration involves setting the mounting base to a U-shape.

[0015] The beneficial effects of one or more of the above technical solutions:

[0016] (1) There are multiple sets of baffles inside the fuel tank. The baffles are distributed at a certain distance. The baffles are welded to the left, right and bottom of the lower cover plate. There is a row of sawtooth notches at the bottom. The function of the baffles is to improve the strength and rigidity of the fuel tank and to reduce the impact of oil due to the shaking of the whole vehicle.

[0017] (2) Six U-shaped mounting seats are symmetrically installed on the left and right sides of the oil tank. There is a reinforcing plate in the middle of the mounting seat to increase the strength and prevent the weld or base material from cracking after being stressed. Attached Figure Description

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1 This section describes the specific implementation method of this embodiment.

[0023] A fuel tank structure for a loader, referring to Figure 1 The tank includes a lower cover plate 1 and an upper cover plate 2. Several partitions 3 are arranged at the bottom of the lower cover plate 1 and along its length. The bottom of each partition 3 has a serrated notch. Several mounting seats 4 are fixed to the sidewalls of the lower cover plate 1 via mounting plates 5. The lower cover plate 1 and the upper cover plate 2 are welded together. The lower surface of the overall fuel tank structure is inclined at a certain angle, less than the vehicle's departure angle, to prevent scratches on inclines and declines. The fuel tank steel plate is made of Q355B high-strength carbon steel. The upper cover plate 2 is 8mm thick, and the welded lower cover plate 1 is 10mm thick.

[0024] The top of the upper cover plate 2 is connected to the breather 10 via an oil pipe. The top of the breather 10 is connected to the filter 11 via an oil pipe. An oil receiving valve 9 is installed on the filling port 8. The oil receiving valve 9 is detached and installed on one side of the filling port 8. The filling port 8 is installed on one side of the lower cover plate 1. Oil is introduced through the filling port 8 to achieve rapid filling. The filling process can be completed within 2 minutes.

[0025] Reference Figure 2 In this embodiment, the refueling process is as follows: the fuel nozzle adds fuel to the fuel tank through the receiving valve. The lower tube of the breather extends into the fuel tank and has a vent and a float. The exhaust side of the breather has a one-way valve, allowing gas to flow only from the inside to the outside. Gas inside the fuel tank can be discharged through the vent of the lower tube of the breather. As fuel is added, the float rises until it seals the vent of the lower tube, sealing the inside of the fuel tank. Gas cannot be discharged, and the internal pressure increases. The fuel nozzle senses the instantaneous pressure increase and automatically shuts off, stopping the refueling process. During operation, fuel is drawn out of the fuel tank, causing the internal pressure to drop and creating a negative pressure. External gas enters the fuel tank through the filter and the breather, balancing the internal pressure. The filter has a one-way valve, allowing gas to flow only from the outside to the inside. Gas discharged during refueling cannot pass through the breather. A return oil assembly 12 and a suction oil assembly 13 are located on one side of the breather 10 and on the top of the upper cover 2. A water tank groove 14 is provided on one side of the breather 10 and on the top of the cover. A recess is located after the upper cover 2 is welded together for installing a water tank.

[0026] A cleaning flange port 7 is provided on the front side of the upper cover plate 2. The interior of the lower cover plate 1 can be cleaned by disassembling the cleaning flange port 7, which facilitates the cleaning of impurities by after-sales service.

[0027] The bottom of the lower cover plate 1 is provided with an oil drain plug 6. The oil can be drained from the bottom of the lower cover plate 1 by removing the oil drain plug 6, which is convenient for after-sales service to clean impurities.

[0028] Mounting base 4 is U-shaped. There are 6 U-shaped mounting bases 4 on the left and right sides of the oil tank. There is a reinforcing plate in the middle of the mounting base 4 to increase strength and prevent the weld or base material from cracking after being stressed.

[0029] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
