Description

Technical Field

[0001] The utility model relates to a hydraulic oil tank for a pure electric transport vehicle and an unmanned transport vehicle, belonging to the technical field of vehicle hydraulic oil tanks. Background Art

[0002] Currently, domestic port machinery generally uses fuel engines as its power source. With the increasing shortage of natural resources such as oil and natural gas, and the severe ecological damage, safety, environmental protection, and energy conservation have become the mainstream of vehicle development. With the rapid development of my country's economy, import and export volumes have increased dramatically. As a result, the scale and daily throughput of ports have gradually expanded over the past decade, and the use of port transport vehicles has become increasingly widespread at ports and terminals, leading to a growing market demand for them. Consequently, there is a growing market demand for higher-quality, more energy-efficient, and environmentally friendly port transport vehicles. To address the national call for energy conservation and emission reduction, our company has developed a pure electric port transport vehicle. Because port transport vehicles involve hydraulic systems, existing hydraulic oil tanks for fuel transport vehicles are bulky, heavy, require a large assembly space, and are prone to oil splashing, making them unsuitable for installation in pure electric port transport vehicles and unmanned electric transport vehicles. Therefore, there is an urgent need for a hydraulic oil tank and transport vehicle for pure electric port transport vehicles that are simple in structure, compact, lightweight, require minimal assembly space, and resist hydraulic oil splashing. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a hydraulic oil tank for a pure electric transport vehicle and an unmanned transport vehicle with a simple structure, small size, light weight, small assembly space occupation, and hydraulic oil not easy to splash.

[0004] The purpose of this utility model is achieved in this way:

[0006] Furthermore, a cabinet is fixedly mounted on the top of the box body for accommodating various components mounted on the top surface of the box body, and a movable panel with a lock is provided on one side surface of the cabinet body through a hinge.

[0007] Furthermore, the porous baffle is S-shaped and runs across the interior of the box, dividing the interior of the box into two containers that are connected through the through holes provided on the porous baffle.

[0008] Furthermore, the blocking baffle includes several oil baffles arranged in sequence from bottom to top in the pipeline connecting the air filter and the inside of the box. The oil baffle is semicircular and has an angle of 45° with the horizontal plane. Two adjacent oil baffles are perpendicular to each other.

[0009] Furthermore, the shock absorber includes multiple layers of rubber shock-absorbing pads or shock-absorbing springs to reduce the vibration generated when the fuel tank receives an impact.

[0010] Furthermore, a recessed oil drain port is provided on the bottom surface of the box body, and a magnetic plug is installed in the oil drain port.

[0011] Furthermore, an unloading valve connected to the oil return filter via a hose is fixedly mounted on the top surface of the box.

[0027] A mounting bracket 9 with a shock absorber 10 and a reinforcing rib plate are installed on the outer side of the box body 1 to ensure that the hydraulic oil tank is firm and reliable. The shock absorber 10 includes multiple layers of rubber shock-absorbing pads or shock-absorbing springs to reduce the vibration generated when the oil tank is impacted.

[0028] The utility model adopts the method of installing the gear pump 3 into the interior of the hydraulic oil tank body 1 to reduce the space occupied by the oil tank, setting a porous baffle inside the box body 1, setting a blocking baffle in the pipeline connecting the air filter 6 with the interior of the box body 1, and installing a mounting bracket 9 with a shock absorber 10 on the side of the box body 1. The overall structure of the oil tank is simple, small in size, light in weight, and prevents hydraulic oil from splashing. It is suitable for use in pure electric port transport vehicles with numerous components and compact structure, especially pure electric unmanned transport vehicles. Example
