Description

Technical Field

[0001] The utility model relates to the technical field of steering pumps, in particular to a steering pump for mining vehicles with a cooling function. Background Art

[0002] Mining trucks are heavy-duty vehicles designed specifically for mining environments, primarily used to transport ore, equipment, and personnel. They typically feature high carrying capacity and powerful power systems to handle rugged terrain and heavy loads, making them widely used in open-pit mines, underground mines, and quarries, greatly improving the efficiency and productivity of mining operations. Due to the heavy load capacity of mining trucks, a steering pump is typically required in the vehicle's steering system to make steering easier and reduce the burden on operators.

[0003] When used, the existing steering pump will create a certain vacuum through the rotation of the internal rotor, sucking the hydraulic oil into the interior, and then transporting the hydraulic oil to the steering system under the rotation of the impeller, thereby generating power assistance to help the driver easily turn the steering wheel.

[0004] However, during the operation of the steering pump, due to internal mechanical friction and flow resistance of the hydraulic oil, a large amount of heat is generated and cannot be discharged in time, causing the temperature of the hydraulic oil to rise and its viscosity to decrease. This will lead to increased leakage in the hydraulic system, reducing the working efficiency and output pressure of the steering pump. At the same time, the oxidation and deterioration rate of the hydraulic oil will be accelerated, resulting in a shortened service life. For this reason, those skilled in the art have proposed a mining truck steering pump with a cooling function to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a steering pump for mining vehicles with a cooling function, which aims to improve the problem in the prior art that a large amount of heat generated during the operation of the steering pump cannot be discharged in time, resulting in an increase in the temperature of the hydraulic oil, a reduction in the working efficiency and output pressure of the steering pump, and a shortened service life.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steering pump for a mining vehicle with a cooling function, comprising a pump body, the oil outlet of the pump body being threadedly connected to a heat sink, the top of the heat sink being fixedly connected to a U-shaped cover, a plurality of heat sinks being fixedly connected between the U-shaped cover and the heat sink, a cooling fan being installed at one end of the top of the heat sink close to the U-shaped cover, the outside of the cooling fan being fixedly connected to a dust net, the inside of the heat sink being fixedly connected to a serpentine tube, the inside of the heat sink being filled with paraffin, the oil inlet of the pump body being threadedly connected to a filter cabin, the inside of the filter cabin being provided with a filter assembly, and the filter assembly being used to filter impurities in the hydraulic oil.

[0007] Further, the filtering component includes a filter element, which is placed inside the filtering chamber. One end of the filter element away from the oil inlet is fixedly connected with a fixing plate, and a plurality of fixing blocks are fixedly connected to the outside of the fixing plate.

[0008] Further, a plurality of limiting grooves are formed inside one side of the filtering chamber away from the oil inlet. The number of the limiting grooves matches that of the fixing blocks, and the limiting grooves are engaged with the fixing blocks.

[0009] Further, a cover plate is fixedly connected to the outside of the filtering chamber, and a second sealing ring is fixedly connected to one side of the cover plate close to the filtering chamber.

[0010] Further, a second sealing groove is formed on one side of the filtering chamber close to the cover plate. The shape of the second sealing groove matches that of the second sealing ring, and the inner wall of the second sealing groove is slidably connected to the outside of the second sealing ring.

[0011] Further, a flange is fixedly connected to one side of the heat dissipation box away from the oil outlet. A first sealing groove is formed on the surface of the flange, and a first sealing ring is arranged inside the first sealing groove.

[0012] Further, a feeding pipe is fixedly connected to the outside of the heat dissipation box, and a sealing cover is threadedly connected to one end of the feeding pipe.

[0013] Further, a plurality of second heat dissipation fins are fixedly connected to the outside of the pump body, and both the second heat dissipation fins and the first heat dissipation fins are made of copper.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the heat dissipated by the serpentine pipe can be absorbed by the paraffin filled inside the heat dissipation box, and the serpentine pipe increases the heat dissipation area, thereby realizing the cooling of the hydraulic oil. At the same time, the operation of the cooling fan can accelerate the air flow, so that after the first heat dissipation fins absorb the heat transferred from the heat dissipation box, the heat can be dissipated faster, improving the heat dissipation efficiency, thereby reducing the temperature of the hydraulic oil, keeping the properties of the hydraulic oil stable during cyclic use, ensuring the working efficiency and output pressure of the steering pump, and the paraffin can be reused repeatedly, reducing the use cost and making the cooling effect better.

[0016] 2. In the present utility model, impurities and particulate matters in the hydraulic oil are filtered out by the filter element, preventing wear and damage to the internal parts of the steering pump, thereby extending the service life of the hydraulic oil and the steering pump. Through the cooperation between multiple fixing blocks and the limiting grooves, the filter element will not rotate inside the filter chamber, ensuring the stability during filtration, and facilitating removal for cleaning or replacement, improving the maintenance efficiency.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: a mining vehicle steering pump with a cooling function, including a pump body 1. The pump body 1 is made of high-strength alloy and has good durability. The oil outlet of the pump body 1 is threadedly connected to a heat dissipation box 2. The heat dissipation box 2 is made of aluminum alloy and has good thermal conductivity, which can transfer heat well. A U-shaped cover 4 is fixedly connected to the top of the heat dissipation box 2. A plurality of first heat dissipation fins 5 are fixedly connected between the U-shaped cover 4 and the heat dissipation box 2. A heat dissipation fan 6 is installed at one end of the top of the heat dissipation box 2 close to the U-shaped cover 4. A dust-proof net 7 is fixedly connected to the outside of the heat dissipation fan 6. A serpentine pipe 8 is fixedly connected to the inside of the heat dissipation box 2. Through the serpentine pipe 8, the hydraulic oil can release heat more fully. The inside of the heat dissipation box 2 is filled with paraffin wax, which can absorb the heat released when the hydraulic oil flows through the serpentine pipe 8. The oil inlet of the pump body 1 is threadedly connected to a filter chamber 3. A filter assembly is arranged inside the filter chamber 3, and the filter assembly is used to filter impurities in the hydraulic oil.

[0026] Specifically, through the threaded connection method, the heat dissipation box 2 is more easily connected to the pump body 1, and at the same time, the sealing performance of the connection can be ensured. The hydraulic oil can enter the inside of the heat dissipation box 2 through the oil outlet and flow into the serpentine pipe 8 inside the heat dissipation box 2. The serpentine design can make the hydraulic oil release heat more fully. At the same time, the inner diameter of the serpentine pipe 8 is smaller than that of the oil outlet, thereby increasing the time for the hydraulic oil to flow through the inside of the heat dissipation box 2, so as to better dissipate heat. Through the paraffin wax filled in the heat dissipation box 2, the dissipated heat can be absorbed, and the paraffin wax can be reused, reducing the use cost. By the operation of the heat dissipation fan 6, the air flow can be accelerated. Then, after the first heat dissipation fins 5 absorb the heat transferred from the heat dissipation box 2, the heat can be dissipated faster, improving the heat dissipation efficiency. At the same time, installing a dust-proof net 7 outside the heat dissipation fan 6 can prevent excessive dust accumulation from affecting the operation of the heat dissipation fan 6 and causing a decrease in wind force. The U-shaped cover 4 is made of aluminum alloy and also has good thermal conductivity, which can dissipate heat well.

[0027] Refer to Figure 4 and Figure 5, the filtering component includes a filter element 13, which is placed inside the filtering chamber 3. The filter element 13 can filter the hydraulic oil to prevent impurities contained therein from affecting the operation of the pump body 1. One end of the filter element 13 away from the oil inlet is fixedly connected to a fixing plate 14, and a plurality of fixing blocks 15 are fixedly connected to the outside of the fixing plate 14. A plurality of limiting grooves 16 are formed inside one side of the filtering chamber 3 away from the oil inlet. The number of the limiting grooves 16 matches that of the fixing blocks 15, and the limiting grooves 16 are engaged with the fixing blocks 15. Through the cooperation of the fixing blocks 15 and the limiting grooves 16, the movement of the filter element 13 inside the filtering chamber 3 can be restricted, so as to maintain stability during filtration. A cover plate 18 is fixedly connected to the outside of the filtering chamber 3. A second sealing ring 19 is fixedly connected to one side of the cover plate 18 close to the filtering chamber 3. The second sealing ring 19 is made of rubber, which can make the filtering chamber 3 and the cover plate 18 have good sealing performance when in use. A second sealing groove 17 is formed on one side of the filtering chamber 3 close to the cover plate 18. The shape of the second sealing groove 17 matches that of the second sealing ring 19, and the inner wall of the second sealing groove 17 is slidably connected to the outside of the second sealing ring 19.

[0028] Specifically, the filter element 13 is installed inside the filtering chamber 3, so that the hydraulic oil can enter the inside of the pump body 1 after being filtered by the filter element 13 inside the filtering chamber 3 first. The impurities and particles in the hydraulic oil are filtered out by the filter element 13, avoiding abrasion and damage to the internal parts of the steering pump, thereby prolonging the service life of the hydraulic oil and the steering pump. Through the cooperation between the plurality of fixing blocks 15 and the limiting grooves 16, the filter element 13 will not rotate inside the filtering chamber 3, thus ensuring the stability during filtration. And the cover plate 18 and the filtering chamber 3 are fixed by screws. Just unscrew the screws to take out the filter element 13 from the inside of the filtering chamber 3, which is convenient for cleaning or replacement, improving the maintenance efficiency. At the same time, at the connection between the filtering chamber 3 and the cover plate 18, through the cooperation of the second sealing groove 17 and the second sealing ring 19, the sealing performance of the connection can be ensured, so that the hydraulic oil will not leak.

[0029] Refer to Figure 1 and Figure 2 , a flange 9 is fixedly connected to one side of the heat dissipation box 2 away from the oil outlet. A first sealing groove 10 is formed on the surface of the flange 9, and a first sealing ring 11 is arranged inside the first sealing groove 10. Through the cooperation of the first sealing groove 10 and the first sealing ring 11, the sealing performance of the connection is better. A charging pipe 12 is fixedly connected to the outside of the heat dissipation box 2. One end of the charging pipe 12 is threadedly connected with a sealing cover, which is convenient for adding paraffin into the heat dissipation box 2. A plurality of second heat dissipation fins 20 are fixedly connected to the outside of the pump body 1. Both the second heat dissipation fins 20 and the first heat dissipation fins 5 are made of copper.

[0030] Specifically, it can be connected to the return pipeline of the hydraulic oil through the flange 9 to achieve the recycling of the hydraulic oil, reduce the usage cost, and improve the sealing performance of the connection through the cooperation between the first sealing groove 10 and the first rubber sealing ring 11. Paraffin can be added to the heat dissipation box 2 through the injection pipe 12 to supplement the consumed paraffin. The heat dissipation effect of the pump body 1 can be further enhanced through the second heat dissipation fins 20, and both the second heat dissipation fins 20 and the first heat dissipation fins 5 are made of copper, with better heat conduction effect.

[0031] Working principle: When using this steering pump, after it is installed in the steering system of the vehicle, the hydraulic oil enters the steering pump through the filter cabin 3. At the same time, the hydraulic oil will pass through the filtration of the filter element 13 to filter out impurities and particulate matters in the hydraulic oil, avoiding abrasion and damage to the internal parts of the steering pump, thereby prolonging the service life of the hydraulic oil and the steering pump. And by unscrewing the screws fixing the cover plate 18, the fixing plate 14 can be pulled to extract the filter element 13 from the inside of the filter cabin 3, facilitating the replacement or cleaning of the filter element 13, thus ensuring the filtration effect.

[0032] Secondly, after the hydraulic oil flows out of the steering pump, it can enter the serpentine pipe 8 inside the heat dissipation box 2. At this time, the paraffin filled inside the heat dissipation box 2 can absorb the heat of the hydraulic oil and start to melt, and the heat will be transferred to the heat dissipation box 2 and then to multiple first heat dissipation fins 5, increasing the contact area with the air to achieve the heat dissipation operation. Then, start the heat dissipation fan 6 to accelerate the air flow speed, which can improve the heat dissipation efficiency, thereby reducing the temperature of the hydraulic oil, keeping the properties of the hydraulic oil stable during recycling, ensuring the working efficiency and output pressure of the steering pump. It is connected to the return pipeline through the flange 9 to make the hydraulic oil recycled. At the same time, through the cooperation between the first sealing groove 10 and the first sealing ring 11, the connection has good sealing performance and the hydraulic oil will not leak.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
