Technical Field
[0001] The utility model relates to the field of hydraulics, in particular to a hydraulic oil tank with dual exhaust functions. Background Art
[0002] Small walking equipment has a compact structure, and the hydraulic oil tank is mostly designed to be long and placed horizontally with the direction of the vehicle body. The speed and movement speed of small walking equipment are fast and frequent, which causes the oil temperature in the hydraulic oil tank to be high. A certain amount of oil vapor is formed in the upper cavity area of the hydraulic oil tank. The upper cavity area of the hydraulic oil tank contains more air. If the hydraulic system returns oil too quickly and the braking condition is sudden, the hydraulic oil in the long hydraulic oil tank increases sharply and churns violently, resulting in excessive pressure in the hydraulic oil tank.

Exhaust pipes are respectively provided on the front and rear sides of the hydraulic oil tank. When the vehicle brakes suddenly and returns oil quickly, there are corresponding exhaust pipes to discharge the gas in the hydraulic oil tank, so that the pressure in the hydraulic oil tank is rapidly reduced and the hydraulic oil cannot overflow;

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Reference Figure 1-3 The utility model provides an embodiment of a hydraulic oil tank with dual exhaust function, including a box body 1, with limit blocks 10 fixedly connected to the left and right sides of the top of the box body 1, a sealing sleeve 11 is provided on the top of the limit block 10, and the top of the sealing sleeve 11 is fixedly connected to the cover plate 2, the four corners of the top of the cover plate 2 are threadedly connected with bolts 3, the bottom ends of the cover plates 2 are all arranged on the top of the box body 1, the lower sides of the outer walls of the bolts 3 are threadedly connected to the inner wall of the box body 1, and the tops of the cover plates 2 are penetrated by lower tubes 12;
[0026] Specifically, by placing the sealing sleeve 11 on the top of the limit block 10, and then using the bolts 3 to install the cover 2 on both sides of the top of the box body 1, the lower tube body 12 on the cover plate 2 can discharge the gas inside the box body 1 and facilitate regular disassembly for maintenance. The setting of the sealing sleeve 11 ensures the overall sealing of the device during use.
[0027] Reference Figure 2-4, the outer wall of the lower tube body 12 is penetrated at the top of the sealing sleeve 11, which is used to discharge the gas in the hydraulic oil tank. The top of the left cover plate 2 is penetrated with an oil suction pipe 4, and the outer wall of the oil suction pipe 4 is penetrated at the inner wall of the left sealing sleeve 11. The top of the right cover plate 2 is penetrated with an oil return pipe 5, and the outer wall of the oil return pipe 5 is penetrated at the inner wall of the right sealing sleeve 11. The bottom end of the lower tube body 12 is fixedly connected with a fixing block 6, and the adjacent side of the bottom end of the fixing block 6 is fixedly connected with a short plate 8, and the opposite side of the bottom end of the fixing block 6 is fixedly connected with a long plate 7. The plate reduces the amount of oil entering the lower tube body 12 due to inertia during braking. The top of the lower tube body 12 is fixedly connected to a blocking chamber 13. The inner wall of the blocking chamber 13 is fixedly connected to a plurality of connecting blocks 14. The opposite end of the connecting block 14 is fixedly connected to a block 15. The block 15 blocks the oil entering the lower tube body 12 and only discharges the gas. The top of the blocking chamber 13 is fixedly connected to the upper tube body 9. The top of the upper tube body 9 is fixedly connected to a protective shell 16. The outer wall of the protective shell 16 is provided with a plurality of vents.
[0028] Specifically, when the equipment suddenly brakes while moving to the left, the hydraulic oil inside the box body 1 will continue to move due to inertia and gather at the bottom end of the left lower tube body 12. At this time, a certain amount of gas will carry part of the hydraulic oil into the lower tube body 12. When the hydraulic oil enters the lower tube body 12, it will be blocked by the connecting block 14 inside the blocking chamber 13, causing the hydraulic oil to flow back into the box body 1, and the gas will continue to rise and be discharged from the protective shell 16. The setting of the blocking chamber 13 makes it possible to prevent the hydraulic oil from spraying out without having to be too long for the upper tube body 9. At this time, the right lower tube body 12 will quickly discharge the gas inside the box body 1 to reduce the air pressure inside the box body 1. The hydraulic oil inside the box body 1 will touch the left side of the inner wall of the box body 1 when moving to the left, and then backflow will occur. At this time, the long plate 7 at the bottom end of the left fixed block 6 will block this part of the hydraulic oil to prevent it from entering the lower tube body 12 again. Similarly, when the equipment moves to the right, the left lower tube body 12 will quickly exhaust the gas. The protective shell 16 set at the top of the upper tube body 9 can prevent foreign objects from falling into the box body 1 and damaging the equipment during daily use.
[0029] Working principle: Place the sealing sleeve 11 on the top of the limit block 10, and then use the bolts 3 to install the cover plate 2 on both sides of the top of the box body 1, so that the lower tube body 12 on the cover plate 2 can discharge the gas inside the box body 1, and is convenient for regular disassembly and maintenance. The setting of the sealing sleeve 11 ensures the overall sealing of the device during use. When the equipment suddenly brakes while moving to the left, the hydraulic oil inside the box body 1 will continue to move due to inertia and gather at the bottom of the lower tube body 12 on the left. At this time, a certain amount of gas will carry part of the hydraulic oil into the lower tube body 12. When the hydraulic oil enters the lower tube body 12, it will be blocked by the connecting block 14 inside the blocking chamber 13, causing the hydraulic oil to flow back into the box. 1, the gas continues to rise and is discharged from the protective shell 16. The setting of the blocking chamber 13 makes it possible to prevent the hydraulic oil from spraying out of the upper tube body 9 without being too long. At the same time, the lower tube body 12 on the right side will quickly discharge the gas inside the box body 1 to reduce the air pressure inside the box body 1. The hydraulic oil inside the box body 1 will touch the left side of the inner wall of the box body 1 when moving to the left, and then backflow will occur. At this time, the long plate 7 at the bottom end of the left fixed block 6 will block this part of the hydraulic oil to prevent it from entering the lower tube body 12 again. Similarly, when the equipment moves to the right, the left lower tube body 12 will quickly exhaust the gas. The protective shell 16 set at the top of the upper tube body 9 can prevent foreign objects from falling into the box body 1 and damaging the equipment during daily use.
