Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, and in particular to a fuel tank structure for mining. Background Art

[0002] At present, the excavator fuel tank is an important component to ensure the normal operation of the excavator. The size of the fuel tank directly affects the continuous working time of the excavator. As the tonnage of the excavator increases, the fuel tank capacity increases accordingly, and the structural strength of the fuel tank weakens.

[0003] The working conditions of super-large tonnage excavators are complex, the vibration of the whole machine is large, and the sloshing of fuel in the fuel tank is increased, which requires high structural strength of the fuel tank. The traditional internal reinforcement structure cannot meet the requirements and is prone to cracking and failure of the fuel tank. Utility Model Content

[0004] The purpose of the utility model is to provide a fuel tank structure for mining in view of the above problems, so as to improve the strength of the fuel tank.

[0005] In order to achieve the above-mentioned purpose, the utility model discloses a fuel tank structure for mining, which includes a enclosure with a cross-sectional shape of П, an outer plate is connected to the opening of the enclosure, a bottom plate is connected between the enclosure and the lower end of the outer plate, a top plate is connected between the enclosure and the upper end of the outer plate, the inner walls of the two side plates of the enclosure are connected to a plurality of horizontally arranged reinforcing cross plates, and the inner wall of the middle plate of the enclosure is connected to a vertically arranged reinforcing vertical plate.

[0006] When in use, the enclosure, outer panels, bottom plate and top plate form a box body. The outer panel also serves as the facade of the whole machine, requiring good structural strength, good flatness and no obvious welding marks; the thickness of the outer panel and bottom plate is greater than that of the enclosure and top plate. Strengthening the vertical plate strengthens the left and right strength, and strengthening the horizontal plate enhances the overall strength, which helps to reduce the impact caused by oil shaking.

[0007] Preferably, both upper and lower edges of the reinforcing vertical plate are provided with vertical plate notches.

[0008] This structure is used to improve the overall strength of the reinforced vertical plate.

[0009] Preferably, a transverse plate notch is provided on the inner edge of the reinforcing transverse plate.

[0010] This structure is used to improve the overall strength of the reinforced cross plate.

[0011] Preferably, a plurality of horizontally arranged rib plates are connected to both sides of the reinforcing vertical plate.

[0012] The rib plate improves the strength of the vertical plate and reduces the impact caused by oil shaking.

[0013] Preferably, the cross-section of the bottom plate is in a stepped shape.

[0014] The bottom plate bears the weight and impact of the fuel tank and fuel, and has relatively high structural requirements. The bending of the bottom plate not only ensures the connection strength with the crossbeam of the whole machine platform, but also allows the bottom of the fuel tank to expand downward to increase the tank capacity. It can also strengthen the bottom plate and optimize the overall force of the fuel tank.

[0015] Preferably, the enclosure is made by bending a steel plate.

[0016] The enclosure of this structure is easy to process and manufacture.

[0017] Preferably, the outer walls of the two side panels of the enclosure are connected to the side mounting seats, and the outer wall of the middle panel of the enclosure is connected to the middle mounting seat.

[0018] When in use, the side of the fuel tank is connected to the whole machine. Compared with the bottom of the fuel tank being connected to the whole machine, the force is more evenly distributed, thus optimizing the overall force of the fuel tank.

[0019] Preferably, a liquid level sensor mounting seat and a liquid level sensor guard plate located on the side of the liquid level sensor mounting seat are installed on the top plate, an oil level sensor fixing tube is connected to the upper part of the bottom plate, and the liquid level sensor mounting seat and the oil level sensor fixing tube are coaxially arranged.

[0020] When in use, the liquid level sensor mounting base is used to install the liquid level sensor, and the oil level sensor fixing tube is used to fix the bottom of the oil level sensor to reduce damage and failure of the sensor caused by oil shaking.

[0021] Preferably, a cleaning flange is installed on the base plate, a sealing ring is arranged between the cleaning flange and the base plate, an oil suction port and a water discharge port are installed on the cleaning flange, and the upper part of the oil suction port protrudes from the upper surface of the base plate; an oil return port is installed on one side plate of the enclosure, a vertically arranged oil return pipe is connected to the inner side of the oil return port, and there is a gap between the lower end of the oil return pipe and the base plate.

[0022] When in use, the upper part of the oil suction port protrudes above the upper surface of the bottom plate to prevent bottom impurities and water from being sucked into the engine. There is a gap between the lower end of the oil return pipe and the bottom plate to reduce the impact of the return oil on the bottom impurities, and the distance from the oil suction port is as far as possible to prevent the return oil from impacting the bottom impurities and being sucked into the oil suction port.

[0023] Preferably, a fuel filler seat, a functional component mounting seat and a cushion block are installed on the top plate.

[0024] When in use, it is used to install other sensors and other components to meet other design requirements of the fuel tank.

[0025] In summary, the beneficial effects of the utility model are as follows: when in use, the enclosure, outer plate, bottom plate and top plate form a box body, and the outer plate also serves as the facade of the whole machine, requiring good structural strength, good flatness and no obvious welding marks; the thickness of the outer plate and bottom plate is greater than that of the enclosure and top plate. Strengthening the vertical plate strengthens the left and right strength, and strengthening the horizontal plate enhances the overall strength, which helps to reduce the impact caused by oil shaking.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0035] like Figures 1 to 3 As shown, a fuel tank structure for mining includes a veneer 2 with a П-shaped cross-section, an outer plate 3 is connected to the opening of the veneer 2, a bottom plate 4 is connected between the lower ends of the veneer 2 and the outer plate 3, a top plate 1 is connected between the upper ends of the veneer 2 and the outer plate 3, the inner walls of the two side plates of the veneer 2 are connected to a plurality of horizontally arranged reinforcing transverse plates 17, and the inner wall of the middle plate of the veneer 2 is connected to a vertically arranged reinforcing vertical plate 15.

[0036] When in use, the enclosure 2, outer panel 3, bottom panel 4 and top panel 1 form a box body, and the outer panel 3 also serves as the facade of the whole machine, requiring good structural strength, good flatness and no obvious welding marks; the thickness of the outer panel 3 and bottom panel 4 is greater than that of the enclosure 2 and top panel 1. The strengthening vertical panel 15 strengthens the left and right strength, and the strengthening horizontal panel 17 enhances the overall strength, which helps to reduce the impact caused by oil shaking.

[0037] The upper and lower edges of the reinforcing upright plate 15 are both provided with upright plate notches.

[0038] This structure is used to improve the overall strength of the reinforcing vertical plate 15 .

[0039] The inner edge of the reinforcing transverse plate 17 is provided with a transverse plate notch.

[0040] This structure is used to improve the overall strength of the reinforcing transverse plate 17 .

[0041] A plurality of horizontally arranged rib plates 16 are connected to both sides of the reinforcing vertical plate 15 .

[0042] The rib plate 16 increases the strength of the reinforcing plate 15 and reduces the impact caused by oil shaking.

[0043] The cross-section of the bottom plate 4 is in a stepped shape.

[0044] The bottom plate 4 bears the weight and impact of the fuel tank and fuel, and has relatively high structural requirements. The bottom plate 4 is bent to ensure the connection strength with the cross beam of the whole machine platform, and to expand the bottom of the fuel tank downward to increase the fuel tank capacity. It can also strengthen the bottom plate 4 and optimize the overall force of the fuel tank.

[0045] The enclosure 2 is made by bending a steel plate.

[0046] The enclosure 2 of this structure is convenient to process and manufacture.

[0047] The outer walls of the two side panels of the enclosure 2 are connected to the side mounting seats 5 , and the outer wall of the middle panel of the enclosure 2 is connected to the middle mounting seat 6 .

[0048] The traditional fuel tank installation fixing point is at the bottom of the fuel tank. After the weight of the fuel tank and the fuel is coupled with the vibration of the whole machine, the force on the bottom is concentrated, which can easily cause the fuel tank to crack and fail. When in use, the side of the fuel tank is connected to the whole machine, which is more evenly stressed than the bottom of the fuel tank is connected to the whole machine, optimizing the overall stress of the fuel tank.

[0049] like Figure 1 , 3 As shown, a liquid level sensor mounting seat 8 and a liquid level sensor guard plate 9 located on the side of the liquid level sensor mounting seat 8 are installed on the top plate 1, an oil level sensor fixing pipe 18 is connected to the upper part of the bottom plate 4, and the liquid level sensor mounting seat 8 is coaxially arranged with the oil level sensor fixing pipe 18. Specifically, the liquid level sensor mounting seat 8 is located in the middle of the top plate 1 to reduce the inaccuracy of the liquid level sensor data caused by the liquid level offset when the excavator is on the ramp.

[0050] When in use, the liquid level sensor mounting seat 8 is used to mount the liquid level sensor, and the oil level sensor fixing tube 18 is used to fix the bottom of the oil level sensor to reduce damage and failure of the sensor caused by oil shaking.

[0051] like Figure 2 , 3 As shown, a cleaning flange 12 is installed on the bottom plate 4, a sealing ring is arranged between the cleaning flange 12 and the bottom plate 4, an oil suction port 13 and a water discharge port 14 are installed on the cleaning flange 12, and the upper part of the oil suction port 13 protrudes from the upper surface of the bottom plate 4; an oil return port 11 is installed on one side plate of the enclosure 2, and a vertically arranged oil return pipe 19 is connected to the inner side of the oil return port 11, and there is a gap between the lower end of the oil return pipe 19 and the bottom plate 4. Specifically, the oil suction port 13 is close to the middle position of the bottom plate 4 to reduce the difficulty of oil suction when the excavator is on a slope when the amount of oil is small. The fuel level sensor mounting seat is close to the oil suction port 13 to reduce the misjudgment caused when the excavator is on a slope when the amount of oil is small.

[0052] When in use, the upper part of the oil suction port 13 protrudes from the upper surface of the bottom plate 4 to prevent bottom impurities and water from being sucked into the engine. There is a gap between the lower end of the return oil pipe 19 and the bottom plate 4 to reduce the impact of the return oil on the bottom impurities, and the distance from the oil suction port 13 is as far as possible to prevent the return oil from impacting the bottom impurities and being sucked into the oil suction port 13.

[0053] A fuel filler seat 10 , a functional component mounting seat 20 and a cushion block 7 are mounted on the top plate 1 .

[0054] When in use, it is used to install other sensors and other components to meet other design requirements of the fuel tank.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
