Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic equipment, and in particular relates to a hydraulic oil tank mechanism which is anti-overflow and anti-leakage. Background Art

[0002] The hydraulic oil tank is one of the important components of the hydraulic system. Hydraulic oil is stored in the hydraulic oil tank. The hydraulic oil will be reduced due to system leakage, or the hydraulic oil must be replaced regularly. At this time, hydraulic oil needs to be added to the hydraulic oil tank. However, for existing hydraulic oil tanks, there are no instructions or markings when workers refuel, which leads to frequent overfilling of the tank, causing the hydraulic oil to overflow, thereby resulting in a large amount of waste of hydraulic oil.

[0003] To this end, an anti-oil overflow hydraulic oil tank with the announcement number "CN217401305U" includes a hydraulic oil tank, an oil inlet pipe is fixedly arranged on the top right side of the hydraulic oil tank, and an oil outlet pipe is fixedly arranged on the bottom left side of the hydraulic oil tank, a guide cylinder is fixedly arranged on the right side of the top of the hydraulic oil tank, and a negative electrode block is fixedly arranged on the top of the inner cavity of the guide cylinder, a guide rod is arranged through the bottom of the guide cylinder, and a moving block is fixedly arranged on the top of the guide rod, a spring is movably arranged on the outer wall of the guide rod and is located below the moving block, and a floating ball is fixedly arranged at the bottom of the guide rod. The hydraulic oil tank is used for effectively ensuring that the foam floating ball is lifted by the buoyancy when the hydraulic oil tank is filled with oil during use, and the staff can easily see the floating ball at the oil inlet pipe, which warns that the hydraulic oil is almost full, so as to prevent oil overflow and reduce the waste of resources.

[0004] However, for the above-mentioned anti-oil overflow hydraulic oil tank, although the vertical movement of the float up and down is effectively guaranteed by setting a guide cylinder, guide rod, moving block, sliding block, slide groove and spring, which is convenient for better warning that the hydraulic oil is almost full, there are still the following obvious defects during use: the above-mentioned hydraulic oil tank will cause the float to push the guide rod upward through the floating of hydraulic oil. Since the thrust of the floating oil to push the float is small, the spring that requires a larger thrust cannot be stretched to drive the guide rod to continue to move upward, resulting in the float being restricted by the stretching of the spring due to the thrust of the oil, so the float cannot push the electrode sheet to contact and perform the anti-overflow alarm, and thus the anti-oil overflow effect of the hydraulic oil tank cannot be achieved. Utility Model Content

[0005] The utility model aims to provide a hydraulic oil tank mechanism which is anti-overflow and anti-leakage, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a hydraulic oil tank mechanism for preventing overflow and oil leakage, comprising:

[0007] A hydraulic oil tank, wherein one side of the end of the hydraulic oil tank is penetrated by an oil filling pipe for filling hydraulic oil into the hydraulic oil tank, and the internal movable lifting of the oil filling pipe is provided with an anti-overflow float for positioning and floating after the hydraulic oil is filled to the warning position of the hydraulic oil tank to seal and block one end of the oil filling pipe;

[0008] A stainless steel outer box, wherein the sealing cover of the stainless steel outer box is connected to the outside of the hydraulic oil tank, and the inner cavity of the stainless steel outer box and the outside of the hydraulic oil tank form a leak-proof filling cavity for filling the inside with leak-proof oil colloid, and one side of the outside of the stainless steel outer box is embedded with an oil level observation transparent plate that penetrates into the hydraulic oil tank for observing the internal hydraulic oil level.

[0010] Preferably, a movable vertical rod is vertically provided at the center position of the top of the anti-overflow float, one end of which passes through the upper end of the cross bar and is fixed with a limiting block, so that the movable vertical rod can be limited on the cross bar when it is movable and raised to prevent it from falling off.

[0011] Preferably, short cross bars are fixed on both sides of one end of the movable vertical rod, and a strip slider that slides directionally in a positioning strip slide groove is vertically fixed to one end of the short cross bar, so that the movable vertical rod will not shake or shift when moving up and down, and can always maintain the position of the up and down movement.

[0012] Preferably, the leak-proof filling cavity formed by the inner cavity of the stainless steel outer box and the outer surface of the hydraulic oil tank is filled with a hydrophobic colloid for expanding and sealing the oil leakage point, which can achieve the effect of expanding and sealing the oil leakage point when oil leakage occurs.

[0013] Preferably, an oil outlet pipe is provided at the bottom of one side of the outer side of the hydraulic oil tank, and one end of the oil outlet pipe is sealed and penetrates to the outer side of the stainless steel outer box, so that the hydraulic oil is discharged through the oil outlet pipe and transported to the hydraulic equipment.

[0016] Compared with the prior art, the technical effects and advantages of the utility model are as follows: the hydraulic oil tank mechanism for preventing overflow and oil leakage, through the combination of the cross bar, the positioning strip slide, the movable vertical bar, the limit block, the short cross bar, the strip slide and the anti-overflow float in the oil filling pipe, makes the hydraulic oil in the hydraulic oil tank continuously rise and contact the anti-overflow float. Due to the buoyancy of the anti-overflow float following the continuous rise of the hydraulic oil, the movable vertical bar continuously moves upward in the cross bar, causing the anti-overflow float to float and seal the port at the bottom of the oil filling pipe. , so that the hydraulic oil is filled to the best position of the hydraulic oil tank and the filling oil inlet pipe is sealed and blocked, so that the hydraulic oil cannot be filled into the hydraulic oil tank, which can ensure that the hydraulic oil tank will not overflow from the injection oil inlet pipe, and the hydraulic oil tank can be prevented from overflowing with a simple structure, which further solves the problem that the comparative document adopts a complex electronic connection method for overflow prevention alarm, and the float ball is limited by the spring tension of the oil thrust, so the float ball cannot push the electrode sheet to contact for overflow prevention alarm.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The utility model provides a technical solution: a hydraulic oil tank mechanism that prevents overflow and oil leakage, comprising:

[0024] The hydraulic oil tank 1 has an oil filling pipe 2 for filling the hydraulic oil into the hydraulic oil tank 1 on one side of the end thereof, and the oil filling pipe 2 is made of stainless steel to prevent rusting under long-term use, thereby enhancing the service life of the hydraulic oil tank 1. The internal movable lifting and lowering of the oil filling pipe 2 is provided with an anti-overflow float 3 for positioning and floating after the hydraulic oil is filled into the hydraulic oil tank 1 and the warning position is good to seal and block one end of the oil filling pipe 2, which can float and block the oil filling pipe 2, and effectively prevent the phenomenon of overflow caused by excessive filling of hydraulic oil, thereby ensuring that Mr. Hu will not have the problem of overflow during the hydraulic oil filling process, and the filling is safer and more assured.

[0025] A stainless steel outer box 4, wherein the sealing cover of the stainless steel outer box 4 is connected to the outside of the hydraulic oil tank 1, so that the stainless steel outer box 4 can protect the hydraulic oil tank 1 and reduce the problem of external force directly hitting the hydraulic oil tank 1, and the inner cavity of the stainless steel outer box 4 and the outside of the hydraulic oil tank 1 form a leak-proof filling cavity 5 for filling the inside with leak-proof oil colloid, and the hydrophobic colloid 13 can be injected into the inside of the leak-proof filling cavity 5 to bond and seal the leakage point when the hydraulic oil leaks. One side of the outside of the stainless steel outer box 4 is embedded with an oil level observation transparent plate 6 that penetrates into the hydraulic oil tank 1 for observing the internal hydraulic oil level, which can observe the specific position of the hydraulic oil filling in the hydraulic oil tank 1 in real time, as well as observe the usage amount and fill it in time.

[0026] The interior of the oil filling inlet pipe 2 is laterally provided with a cross bar 7 of a mesh structure, which not only does not affect the filling of the hydraulic oil, but also facilitates the flexible up and down movement of the movable vertical rod 9. The inner wall of the bottom end of the oil filling inlet pipe 2 is provided with positioning strip slide grooves 8 on both sides, which can enable the anti-overflow float 3 to move upward in a vertically stable state during the floating process. The top center position of the anti-overflow float 3 is vertically provided with a movable vertical rod 9, which can keep the anti-overflow float 3 in a stable state to block the oil filling inlet pipe 2 for epidemic prevention. The movable vertical rod 9 has one end that passes through the upper end of the cross bar 7 and is fixed with a limited position block 10, so that the movable vertical rod 9 will not be separated from the cross bar 7 during the downward movement. Short cross bars 11 are fixed on both sides of one end of the movable vertical rod 9. One end of the short cross bar 11 is vertically fixed with a strip slider 12 that slides directionally in the positioning strip slide groove 8, so that the anti-overflow float 3 can float stably in the hydraulic oil tank 1 to block the filling oil inlet pipe 2 and prevent excessive filling and overflow.

[0027] The leak-proof filling cavity 5 formed by the inner cavity of the stainless steel outer box 4 and the outer surface of the hydraulic oil tank 1 is filled with a hydrophobic colloid 13 for expanding and plugging the oil leakage point. The hydrophobic colloid 13 will expand when it contacts the outflowing hydraulic oil. This is because the structure of these colloids enables them to absorb liquid, and after absorbing the liquid, they will expand to plug the oil leakage point and prevent leakage. In addition, the oil-producing hydrophobic polymer, silica gel, oxide nanoparticles, nanocarbon materials, surfactants, nanocomposites and other materials are compositely composed, and the material selection and preparation method of the hydrophobic colloid 13 can be adjusted and optimized according to specific application requirements. , to obtain a hydrophobic colloid 13 with ideal performance. An oil outlet pipe 14 is provided at the bottom of one side of the outside of the hydraulic oil tank 1, which is used to transport the filled hydraulic oil to various hydraulic equipment for use. One end of the oil outlet pipe 14 is sealed and penetrates to the outside of the stainless steel outer box 4. Support pads 15 for horizontally supporting the hydraulic oil tank 1 are provided on both sides of the bottom of the stainless steel outer box 4. A mounting base plate 16 is horizontally fixed to the bottom of the support pad 15. An oil collecting trough 17 for collecting oil leakage from the bottom of the stainless steel outer box 4 is provided around the bottom edge of the outer surface of the stainless steel outer box 4, which has the effect of collecting the leaked oil.

[0028] Specifically, when in use, first connect the oil pump filling pipe with the filling inlet pipe 2 to fill the hydraulic oil tank 1 with hydraulic oil, and continuously add hydraulic oil to the hydraulic oil tank 1 until it reaches the highest position and contacts the anti-overflow float 3 to make it float upward. The upward movement of the anti-overflow float 3 pushes the movable vertical rod 9 to interactively move upward in the cross bar 7, and the upward movement of the movable vertical rod 9 utilizes the strip slider 12 on the short cross bar 11 to slide upward in the positioning strip slide groove 8 to ensure the stability of the upward movement of the movable vertical rod 9 and keep the anti-overflow float 3 moving vertically upward. After the hydraulic oil is filled to the highest position of the hydraulic oil tank 1, the anti-overflow float 3 can seal the bottom end of the filling inlet pipe 2, thereby After the hydraulic oil is filled to the highest position, the filling oil inlet pipe 2 can be anti-overflow and blocked. A simple anti-overflow structure can be used to prevent the hydraulic oil tank 1 from overflowing, thereby avoiding the phenomenon of overflow caused by excessive filling of hydraulic oil. When the hydraulic oil flows out of the hydraulic oil tank 1, the leaked hydraulic oil is allowed to contact the hydrophobic colloid 13. The hydrophobic colloid 13 utilizes its own expansion effect when in contact with the liquid to expand the hydrophobic colloid 13 to expand, bond and block the oil leakage point of the hydraulic oil tank 1, thereby being able to expand and block the oil leakage point of the hydraulic oil tank 1 in time, avoiding the problem of large-scale oil leakage in the hydraulic oil tank 1, and further enhancing the anti-leakage effect of the hydraulic oil tank 1.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
