Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically to an integrated hydraulic oil tank for underground mining trucks. Background Technology

[0002] During operation, the hydraulic oil stored in the hydraulic tank of an underground mining truck serves as the medium for the entire hydraulic system. The design of the hydraulic tank significantly impacts the system's performance. Traditional hydraulic tank designs separate the hydraulic oil for the working system and the braking system into two separate tanks, increasing the space occupied by each tank.

[0003] When hydraulic oil tanks need maintenance or cleaning, the hydraulic oil inside needs to be drained. However, existing hydraulic oil tanks usually drain oil through a drain port, which poses a risk of slow draining speed and secondary contamination of the hydraulic oil. Utility Model Content

[0004] The purpose of this invention is to provide an integrated hydraulic oil tank for underground mining trucks, which solves the problems mentioned in the background art of existing oil tanks being space-consuming and inconvenient for draining oil.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated hydraulic oil tank for underground mining trucks, comprising an oil tank body and an oil pumping mechanism disposed on the oil tank body. The interior of the oil tank body is divided into four chambers by multiple partition plates, namely a first chamber, a second chamber, a third chamber, and a fourth chamber. Two oil pumping mechanisms are provided, one of which is connected to the first and third chambers, and the other of which is connected to the second and fourth chambers.

[0006] Furthermore, the oil extraction mechanism includes an oil extraction pipe and a hydraulic pump; the hydraulic pump is located at the bottom of the oil tank body and its inlet and outlet are connected to the oil extraction pipe.

[0007] Furthermore, a filter is provided on the oil extraction pipe.

[0008] Furthermore, the oil tank body is provided with oil filling ports that communicate with the first chamber and the third chamber respectively.

[0009] Furthermore, the bottom of the oil tank body is provided with an oil drain port that communicates with the first chamber, the second chamber, the third chamber and the fourth chamber respectively.

[0010] Furthermore, the side wall of the oil tank body is provided with oil outlets that communicate with the first chamber and the third chamber respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. Saves installation space: The oil tank body of this utility model is divided into four chambers by partition plates. The first and second chambers respectively contain the hydraulic oil used in the working system and braking system of the mining truck hydraulic system. The hydraulic oil that originally needed to be stored in two oil tanks is integrated into one tank, which effectively saves installation space, makes the spatial layout of the underground mining truck more compact and reasonable, and improves the space utilization rate.

[0013] 2. Facilitates oil draining and reduces the risk of secondary contamination: This invention incorporates an oil extraction mechanism, including an oil extraction pipe and a hydraulic pump. When the oil tank requires maintenance, repair, or cleaning, the hydraulic pump is activated to quickly extract the hydraulic oil from the first and second chambers to the third and fourth chambers for temporary storage. Furthermore, the oil extraction pipe is equipped with a filter, which filters the hydraulic oil during the extraction process, reducing impurities. Compared to traditional oil draining methods, this accelerates the draining process, reduces the risk of secondary contamination of the hydraulic oil, ensures the cleanliness of the hydraulic oil, and helps extend the service life of the hydraulic oil and ensure the stable operation of the hydraulic system.

[0020] Please see Figures 1 to 4An integrated hydraulic oil tank for underground mining trucks is disclosed, comprising a tank body 1 and an oil suction mechanism mounted on the tank body 1. The tank body 1, used in the hydraulic system of the mining truck, consists of a tank body, an oil level gauge, an oil inlet 10, an oil outlet 11, an oil outlet 12, a return oil outlet, an oil suction filter, a return oil filter, an air filter, a partition plate 2, an oil temperature sensor, and a level switch. The oil level gauge, mounted on the side of the tank body and used in conjunction with the level switch, alerts the operator to the oil level in the tank. The return oil outlet is located on the tank body. The oil suction filter is installed inside the tank near the bottom; its function is to filter out large particulate impurities in the hydraulic oil, preventing these impurities from entering the pump body and thus protecting the pump body and other hydraulic components from damage. The oil suction filter, installed at the return oil outlet of the tank body, filters impurities, metal shavings, and contaminants from the oil returning from the hydraulic system to the tank, ensuring oil cleanliness and preventing impurities from re-entering the hydraulic system. The air filter, also known as a breather valve, is installed on top of the oil tank. Its function is to balance the air pressure inside and outside the oil tank, allowing the oil to flow smoothly in and out of the tank, while filtering the air entering the tank to prevent dust and other impurities from contaminating the oil. The oil temperature sensor monitors the hydraulic oil temperature in real time and transmits the temperature signal to the vehicle's control system. When the oil temperature is too high or too low, the control system can take appropriate measures, such as activating the cooling fan or heating device, to ensure the hydraulic system operates within a suitable temperature range.

[0021] The internal structure of the oil tank body 1 is divided into four chambers by multiple partitions 2: a first chamber 3, a second chamber 4, a third chamber 5, and a fourth chamber 6. Two oil inlets 10 are provided, communicating with the first chamber 3 and the third chamber 5 respectively. These are the inlets for adding hydraulic oil to the tank, typically located at the top of the tank or in an easily accessible position. They are equipped with sealing caps to prevent dust, debris, etc., from entering the tank during refueling. Four oil drain ports 11 are provided, located at the bottom of the tank and communicating with the first chamber 3, the second chamber 4, the third chamber 5, and the fourth chamber 6 respectively. These are used to drain the hydraulic oil from the tank for maintenance, such as oil replacement or cleaning of impurities at the bottom of the tank. The drain ports are usually equipped with drain valves to control the draining speed and flow rate. Oil outlets 12 are located on the side wall of the tank and communicate with the first chamber 3 and the second chamber 4 respectively.

[0022] The oil extraction mechanism consists of two sets, each composed of an oil extraction pipe 7 and a hydraulic pump 8. One oil extraction pipe 7 connects to the bottom of the first chamber 3 and the third chamber 5 at both ends, while the other oil extraction pipe 7 connects to the second chamber 4 and the fourth chamber 6 at both ends, with sealing rings at the connections. Two hydraulic pumps 8 are mounted on the two oil extraction pipes 7, and filters 9 are installed on both oil extraction pipes 7. Specifically, the hydraulic pumps 8 are bidirectional vane pumps, powered by the mining truck's electrical system (the electrical system drives the engine, which in turn drives the hydraulic pumps 8). The filters 9 are mesh filters.

[0023] The working principle of this utility model is as follows: The interior of the oil tank body 1 is divided into a first chamber 3, a second chamber 4, a third chamber 5, and a fourth chamber 6 by multiple partition plates 2. The first chamber 3 and the second chamber 4 are respectively used to hold the hydraulic oil used in the working system and braking system of the mining truck hydraulic system. By integrating the first chamber 3 and the second chamber 4 into one tank, installation space is saved.

[0024] When the oil tank body 1 needs maintenance, repair or cleaning, the two hydraulic pumps 8 are started to pump the hydraulic oil in the first chamber 3 and the second chamber 4 to the third chamber 5 and the fourth chamber 6, which are used as backups. After the maintenance, repair or cleaning is completed, the hydraulic oil is pumped back into the first chamber 3 and the second chamber 4 through the hydraulic pumps 8. The filter 9 installed on the oil extraction pipe 7 can be used to filter the hydraulic oil.
