Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to an oil tank and engineering machinery equipment. Background Art

[0002] When construction machinery equipment such as forklifts or shovels are started or braked during operation, the hydraulic oil in the tank will fluctuate. When the speed of sudden start is too fast or sudden braking occurs, the fluctuation amplitude increases, which may cause the hydraulic oil to overflow from the breathing port of the tank. In addition, the hydraulic oil flows out of the tank and enters the oil supply system. The oil supply system supplies the hydraulic oil to the hydraulic system, and finally the oil return system returns the hydraulic oil of the hydraulic system to the tank. After a working cycle, the temperature of the hydraulic oil rises. If the high-temperature hydraulic oil is immediately extracted by the oil supply system and supplied to the hydraulic system to continue the next working cycle, it is easy to cause the temperature of the hydraulic oil to get out of control.

[0003] In the prior art, a partition is usually arranged inside the oil tank, and the partition is used to divide the interior of the oil tank into multiple cavities. The partition can reduce the fluctuation amplitude of the hydraulic oil. At the same time, the partition divides the oil tank into a cooling chamber and a supply chamber. The supply chamber provides hydraulic oil to the oil supply system, and the return oil system returns the high-temperature hydraulic oil to the cooling chamber. Due to the barrier effect of the partition, the high-temperature hydraulic oil stays in the cooling chamber for a longer time, and the temperature drops. After the temperature drops, the hydraulic oil flows to the supply chamber again.

[0004] However, most of the existing partitions are fixed to the inside of the fuel tank by welding, and the partitions are not removable. When the fuel tank needs to be cleaned, the spray gun inserted into the fuel tank from the top is blocked by the partition, and the cleaning angle is greatly limited. There is a large range of cleaning dead angles inside the fuel tank, and the cleaning efficiency is low.

[0005] Therefore, there is an urgent need for an oil tank and engineering machinery equipment to solve the above problems. Utility Model Content

[0007] To achieve this purpose, the utility model adopts the following technical solutions:

[0008] An oil tank, the oil tank comprises a box body, an oil storage chamber is provided inside the box body, the oil storage chamber is provided with a partition assembly, the partition assembly comprises a fixed plate and an adjustment plate, the fixed plate is vertically fixed to the bottom of the oil storage chamber, the bottom of the fixed plate is provided with a notch, the adjustment plate is detachably installed on the top of the fixed plate, the fixed plate and the adjustment plate separate the oil storage chamber into a hot oil chamber and a cold oil chamber, the bottom of the hot oil chamber is connected with the bottom of the cold oil chamber through the notch.

[0012] As an optional technical solution, the elongated groove is provided in the fixing plate, and the mounting hole is provided in the adjusting plate.

[0018] Beneficial effects of the utility model:

[0019] The utility model provides an oil tank and engineering machinery equipment. The oil tank includes a box body, an oil storage chamber is provided inside the box body, and the oil storage chamber is provided with a partition assembly. The partition assembly includes a fixed plate and an adjustment plate. The fixed plate is vertically fixed to the bottom of the oil storage chamber, a notch is provided at the bottom of the fixed plate, and the adjustment plate is detachably installed on the top of the fixed plate. The fixed plate and the adjustment plate divide the oil storage chamber into a hot oil chamber and a cold oil chamber, and the bottom of the hot oil chamber is connected with the bottom of the cold oil chamber through the notch. The hot oil chamber and the cold oil chamber can both store hydraulic oil. Due to the blocking effect of the fixed plate and the adjustment plate, the fluctuation amplitude of the hydraulic oil in the hot oil chamber and the cold oil chamber is reduced, and the retention time of the hydraulic oil in the hot oil chamber is extended, which can prevent the high-temperature hydraulic oil that has just returned to the hot oil chamber from immediately entering the cold oil chamber, and prevent the high-temperature hydraulic oil from entering the next working cycle and continuing to heat up. After the hydraulic oil in the hot oil chamber is cooled, the hydraulic oil with a lower temperature sinks and passes through the notch into the cold oil chamber to prepare to enter the oil supply system.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0030] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] This embodiment provides engineering machinery equipment, which includes an oil supply system, an oil return system and an oil tank. The oil supply system is connected to a cold oil chamber 12 of the oil tank, and the oil return system is connected to a hot oil chamber 11 of the oil tank.

[0032] like Figures 1 to 4 As shown, the oil tank of this embodiment includes a box body 1, an oil storage chamber is provided inside the box body 1, and the oil storage chamber is provided with a partition assembly 2, the partition assembly 2 includes a fixed plate 21 and an adjusting plate 22, the fixed plate 21 is vertically fixed to the bottom of the oil storage chamber, a groove 211 is provided at the bottom of the fixed plate 21, and the adjusting plate 22 is detachably installed on the top of the fixed plate 21, and the fixed plate 21 and the adjusting plate 22 divide the oil storage chamber into a hot oil chamber 11 and a cold oil chamber 12, and the bottom of the hot oil chamber 11 is connected with the bottom of the cold oil chamber 12 through the groove 211.

[0033] In this embodiment, the engineering machinery equipment is a forklift. In some other embodiments, the engineering machinery equipment is a shovel truck or a mining truck.

[0034] When the construction machinery starts moving or braking, the hydraulic oil inside the tank fluctuates. Since the tank of this embodiment is provided with a partition assembly 2 for blocking, the fluctuation amplitude of the hydraulic oil in the hot oil chamber 11 and the cold oil chamber 12 is reduced, thereby preventing the hydraulic oil from overflowing from the breathing port or other positions.

[0035] When the construction machinery equipment is operating, for example, when a forklift is transporting materials, the oil supply system extracts the hydraulic oil from the cold oil chamber 12 and delivers the hydraulic oil to the hydraulic system to realize the operation of transporting materials. In this process, the hydraulic oil absorbs heat and its temperature rises and flows back to the hot oil chamber 11 through the oil return system. Due to the blocking effect of the fixed plate 21 and the adjusting plate 22, the retention time of the hydraulic oil in the hot oil chamber 11 is extended, and the heat dissipation time of the hydraulic oil in the hot oil chamber 11 is increased, which can prevent the high-temperature hydraulic oil that has just returned to the hot oil chamber 11 from immediately entering the cold oil chamber 12, thereby preventing the high-temperature hydraulic oil from entering the next working cycle and continuing to heat up. It is known from common knowledge that in a liquid state, the density of low-temperature hydraulic oil is higher than that of high-temperature hydraulic oil. Due to heat dissipation, the temperature of the hydraulic oil that enters the hot oil chamber 11 first is lower than the temperature of the hydraulic oil that enters the hot oil chamber 11 later. The hydraulic oil with a lower temperature sinks to the bottom of the hot oil chamber 11. When the oil supply system draws hydraulic oil from the cold oil chamber 12, due to the hydraulic pressure difference, the low-temperature hydraulic oil at the bottom of the hot oil chamber 11 passes through the slot 211 and enters the cold oil chamber 12, thereby providing the oil supply system with hydraulic oil with a lower temperature.

[0036] When the oil tank of the engineering machinery needs to be cleaned, the spray gun is inserted into the oil tank and the adjustment plate 22 is removed from the fixed plate 21. The height of the partition assembly 2 is lowered and the cleaning angle of the spray gun is increased, which can reduce the cleaning dead angle and achieve a better cleaning effect.

[0037] Compared with an oil tank without a partition, the oil tank provided in this embodiment can reduce the temperature of the hydraulic oil in the cold oil chamber 12 by 5 to 10° C.

[0038] In this embodiment, a drain port is provided at the bottom of the oil tank, and the cleaning liquid sprayed into the hot oil chamber 11 or the cold oil chamber 12 can pass through the notch 211 and finally be discharged from the drain port.

[0039] In this embodiment, the fixing plate 21 is fixed to the box body 1 by welding to ensure sufficient connection strength. In some other embodiments, the fixing plate 21 is fixed to the box body 1 by bolts 23.

[0040] In this embodiment, the partition assembly 2 further includes a bolt 23 and a nut 24, wherein the bolt 23 passes through the fixed plate 21 and the adjusting plate 22, and the nut 24 is sleeved on the periphery of the bolt 23 to lock the adjusting plate 22 to the top of the fixed plate 21. In some other embodiments, the partition assembly 2 includes a clip, and the adjusting plate 22 is clamped and fixed to the fixed plate 21 by the clip.

[0041] Optionally, one of the fixing plate 21 and the adjusting plate 22 is provided with a long slot 212, the long slot 212 extends in the vertical direction, and the other of the fixing plate 21 and the adjusting plate 22 is provided with a mounting hole 221, the bolt 23 passes through the long slot 212 and the mounting hole 221, and the adjusting plate 22 is adjustable and mounted on the fixing plate 21 in the vertical direction. When it is necessary to adjust the height of the adjusting plate 22, the nut 24 is loosened to allow the bolt 23 to slide in the long slot 212, and the nut 24 is tightened after the adjusting plate 22 reaches a preset position to fix the adjusting plate 22 at a preset height.

[0042] In this embodiment, the long slot 212 is formed in the fixing plate 21 , and the mounting hole 221 is formed in the adjusting plate 22 . In some other embodiments, the long slot 212 is formed in the adjusting plate 22 , and the mounting hole 221 is formed in the fixing plate 21 .

[0043] When the height of the adjustment plate 22 is raised, the hydraulic oil that passes over the adjustment plate 22 from the top is further reduced. In order to provide hydraulic oil to the cold oil chamber 12 in time, the present embodiment extends the length of the long groove 212 in the vertical direction. When the mounting hole 221 is opposite to the upper end of the long groove 212, the bottom end of the long groove 212 is connected to the hot oil chamber 11 and the cold oil chamber 12, and the hydraulic oil in the hot oil chamber 11 can pass through the bottom end of the long groove 212 and enter the cold oil chamber 12.

[0044] Optionally, the top of the box body 1 is provided with an opening 13, and the opening 13 faces the partition assembly 2. The spray gun can pass through the opening 13 to enter the interior of the box body 1, clean the cavities on both sides of the partition assembly 2, and can also observe the hot oil chamber 11 or the cold oil chamber 12 through the opening 13.

[0045] Optionally, a notch 211 is respectively provided on both sides of the bottom of the fixing plate 21 , and the two notches 211 at the bottom of the fixing plate 21 correspond one-to-one to the two side walls of the box body 1 .
