Description

Technical Field

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

[0002] As a key piece of equipment for mining and transportation, underground mining trucks rely on their hydraulic systems to provide the necessary power and control functions. The hydraulic oil tank, as an important component of the hydraulic system, not only stores oil, dissipates heat, and settles impurities, but its structural design also directly affects the operational stability of the hydraulic system and the overall reliability of the vehicle.

[0003] Currently, the hydraulic oil tanks of underground mining trucks are generally designed using a "form-fitting design" method, which means adapting the tank's shape to the specific vehicle's chassis layout and the spatial constraints of surrounding components. While this method can meet basic usage requirements to a certain extent, the following prominent problems have gradually emerged in long-term practical application: First, existing design methods result in poor versatility for hydraulic tanks. Different vehicle models, and even different modifications within the same model series, often require redesigning the tank's shape and installation structure, making the tank a non-standard component. This not only increases design workload but also leads to a wide variety of spare parts, increasing production management costs and inventory pressure. During equipment maintenance, it is difficult to quickly replace tank components on-site, severely impacting equipment uptime.

[0004] Secondly, development costs are high. Developing a new mining truck requires the separate design, prototyping, and verification of the hydraulic tank. This process involves multiple stages, including structural design, strength analysis, tooling preparation, sample production, and performance testing, consuming significant time and financial resources. Furthermore, non-standard design makes it difficult to standardize production processes, resulting in low production efficiency and difficulty in effectively controlling production costs.

[0005] Furthermore, the design lacks consideration for human factors. Traditional hydraulic tanks have not been adequately optimized in terms of lifting point placement and maintenance operation space, which makes on-site installation, disassembly, and maintenance operations difficult, increases the labor intensity of operators, and even poses certain safety hazards.

[0006] Therefore, there is an urgent need for a new hydraulic tank design that can fundamentally solve the above problems, improve the product's versatility, economy, and aesthetics while ensuring functionality, and meet the higher requirements of modern mining equipment for reliability, maintainability, and appearance quality. Utility Model Content

[0007] The purpose of this utility model is to provide a hydraulic oil tank for mining trucks to solve the problems of insufficient capacity, difficult installation and maintenance, and lack of aesthetic appeal when integrated with the vehicle.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic oil tank for mining trucks, comprising a hydraulic oil tank body, which is composed of a curved plate, a top cover plate, a bending plate, and a partition plate; the top cover plate is provided with a return port, a fill port, and a suction port flange; the return port is used to connect to a return seat to realize the return of hydraulic oil; the fill port is connected to a second steel pipe, which is used to connect to an air filter to realize air exchange between the hydraulic oil tank and the outside environment and to add hydraulic oil; the suction port flange is used to connect to a suction pipe to provide hydraulic oil to the hydraulic system; the hydraulic oil tank body is internally provided with an elbow, a first steel pipe, a connecting threaded sleeve, a threaded connecting pipe, and a suction filter flange; the suction filter flange is connected to a suction filter to realize the output of hydraulic oil; a cleaning seat is welded to the outside of the hydraulic oil tank body, and the cleaning seat is fitted with a cleaning cover to realize the cleaning of the hydraulic oil tank; an oil drain port is provided at the bottom of the hydraulic oil tank body to release hydraulic oil during cleaning; a handle is also provided on the hydraulic oil tank body for lifting the hydraulic oil tank.

[0009] Preferably, the elbow, the first steel pipe, the connecting threaded sleeve, the threaded connecting pipe, and the oil suction filter flange are fixed inside the hydraulic oil tank body by welding or threaded connection.

[0010] Preferably, the cleaning seat is welded to the side or top of the hydraulic oil tank body, and the cleaning cover is detachably connected to the cleaning seat by threads or snaps.

[0011] Preferably, the drain port is located at the lowest point of the hydraulic oil tank body and is installed by a threaded connection to completely drain the hydraulic oil.

[0012] Preferably, the handles are symmetrically arranged on both sides of the hydraulic oil tank body and fixed by welding or bolts for balanced hoisting.

[0013] The working process of this utility model is as follows: First, steel plate components are cut and processed according to design dimensions. Bending plates and folded plates are formed using a bending machine and then welded to the top cover plate to form the outer shell of the oil tank. Next, partitions and internal support components are welded. Then, the functional components are installed: the return oil port, filler oil port, and suction oil port flanges are welded to the designated positions on the top cover plate; the suction pipeline system is assembled inside the oil tank, including elbows, steel pipes, threaded connecting sleeves, threaded connecting pipes, and suction filter flanges; the cleaning seat, drain port, and handle are welded externally. Finally, an overall inspection is conducted, including dimensional checks, pressure tests, sealing tests, and internal cleanliness checks.

[0014] The beneficial effects of this utility model are as follows: (1) This utility model significantly improves the effective volume and space utilization of the hydraulic oil tank through an optimized structure consisting of a curved plate, a top cover plate, a bent plate, and internal partitions. This structure not only ensures the rigidity and strength of the oil tank body, enabling it to withstand vibrations and impacts under complex underground working conditions, but also effectively guides the oil flow path through its rationally arranged internal partitions, promoting the precipitation of impurities in the oil, thereby improving the working stability and reliability of the hydraulic system and fundamentally guaranteeing the continuous operation capability of mining trucks.

[0015] (2) The rational layout of the functional interfaces of the fuel tank body in this utility model greatly improves the convenience of installation and maintenance. The clearly distinguished return port, filler port and suction port avoid confusion in pipeline connections; the specially designed cleaning seat and drain port work together to make internal cleaning and oil replacement operations more thorough and convenient; and the symmetrically arranged handles provide safe and labor-saving conditions for lifting and moving the fuel tank. These design details effectively reduce the labor intensity and working time of maintenance personnel, while reducing the risk of failure caused by improper maintenance and improving the safety of the whole vehicle.

[0016] (3) This utility model achieves a unity of functionality, versatility, and aesthetics. The modular design allows the hydraulic tank to adapt to the installation requirements of different models of mining trucks, significantly reducing the repetitive design costs and production inputs required due to vehicle model changes. At the same time, its neat and simple external shape makes the tank consistent with the overall appearance of the vehicle, improving the overall appearance of the mining equipment.
