Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for aircraft hydraulic systems, and particularly relates to an aircraft ground hydraulic pressure supply device. Background Art

[0002] An aircraft hydraulic system refers to a complete set of devices on an aircraft that uses oil as the working medium and drives actuators to complete specific manipulation actions by hydraulic pressure. To ensure the safety and reliability of pressure supply, modern aircraft generally have several independent hydraulic source systems, which are specifically composed of a main hydraulic system, an auxiliary hydraulic system, a ground service system, and a hydraulic indication system. When the aircraft is not started, a ground hydraulic pressure supply device is needed to supply pressure. The hydraulic pressure supply device includes a hydraulic system, which is used to provide the pressure and flow required for cleaning and debugging the aircraft hydraulic system, refuel and drain the aircraft hydraulic oil tank, and refuel the hydraulic pressure supply device itself, and a device for lifting the housing of the hydraulic pressure supply device to facilitate internal maintenance of the hydraulic pressure supply device.

[0003] Although the existing ground hydraulic pressure supply device can supply pressure to the aircraft hydraulic system, its interior is relatively enclosed. When the internal components work, they will generate relatively high heat, and the discharge of this heat is relatively slow, which will accumulate inside the pressure supply device, resulting in too high an internal temperature and affecting the normal operation of the internal components.

Detailed implementation manners

[0027] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail the specific embodiments of the "aircraft ground hydraulic pressure supply device" of the present utility model with reference to the accompanying drawings.

[0028] See Figures 1-5, in this embodiment, the hydraulic pressure supply device includes a base 100, on which a housing 200 is provided to form a closed space, and a hydraulic system (not shown) is arranged in the closed space; a hollowed-out window 202 is provided on the front side wall 201 of the housing 200, and a first motor 204 and a first lead screw 205 are arranged inside the rear side wall 203 of the housing 200. A first slider 206 is arranged on the first lead screw 205, and a blower assembly is arranged on the first slider 206. The blower assembly faces the hollowed-out window 202; the first motor 204 drives the first lead screw 205 to rotate, thereby driving the first slider 206 to slide along the first lead screw 205, so as to drive the blower assembly to blow air towards the hollowed-out window 202 while moving. The moving air supply of the blower assembly can send out the heat generated at different positions inside the device through the air from the hollowed-out window 202, achieving effective cooling of the inside of the device and providing a normal working temperature environment for the components inside the device.

[0029] Further referring to Figure 4 and Figure 5 , in this embodiment, the blower assembly includes a second motor 207 and a main blade 208. The second motor 207 drives the main blade 208 to rotate to blow air, with a simple design and convenient installation.

[0030] Furthermore, in this embodiment, in order to enhance the air-cooling effect, the blower assembly further includes a pulley 209 and a driven blade 210. Pulley key grooves are arranged on both the second motor 207 and the driven blade 210. The pulley 209 is connected to the second motor 207 and the driven blade 210 through the key grooves. While the second motor 207 drives the main blade 208 to rotate, it also drives the driven blade 210 to rotate through the pulley 209. Such a setting can increase the blowing area and improve the heat dissipation effect without additionally increasing the motor. It should be noted that one driven blade is provided in this embodiment, and in other embodiments, multiple driven blades can be provided according to needs to further improve the heat dissipation effect.

[0031] Further referring to Figure 3 and Figure 5 , in this embodiment, a third motor 211 is arranged inside the front side wall 201. The third motor 211 is connected to a second lead screw 212. A second slider 213 is sleeved on the second lead screw 212, and a cleaning brush 214 is arranged on the second slider 213. The cleaning brush 214 abuts against the inner side of the hollowed-out window 202; the third motor 211 drives the second lead screw 212 to rotate, thereby driving the second slider 213 to move along the second lead screw 212, so as to drive the cleaning brush 214 to move to clean the entire hollowed-out window 202 and prevent the hollowed-out window 202 from being blocked and unable to dissipate heat by air cooling.

[0032] More specifically, in this embodiment, a sliding column 215 is fixedly connected to the inner wall of the housing 200. The sliding column 215 is parallel to the second lead screw 212. The second slider 213 is sleeved on the sliding column 215 and slides up and down along the sliding column 215 to ensure that the cleaning brush 214 does not shake during sliding cleaning and ensure the stability of cleaning.

[0033] Meanwhile, in this embodiment, in order to prevent the dust generated during cleaning from accumulating on the base 100, a dust collection box 216 is detachably arranged inside the front side wall 201. The dust collection box 216 has an upward opening and is located below the hollowed window 202.

[0034] Further referring to Figures 1-4 , in this embodiment, a universal wheel shaft 101 and a driven wheel shaft 102 are arranged at the bottom of the base 100. The universal wheel shaft 101 is connected to a traction control head 103 to facilitate the movement and transportation of the pressure supply device.

[0035] More specifically, in this embodiment, the bottom edge of the right side surface of the housing 200 is hinged to the base 100 to facilitate opening the housing 200 for overhaul and maintenance of the hydraulic system inside the device; lifting rings 217 are arranged on both the base 100 and the housing 200 to facilitate lifting the pressure supply device using a crane; a hanging rack 218 is also arranged on the housing 200 for winding and placing pipelines and wires.

[0036] Further referring to Figures 1-4 and Figure 6 , in this embodiment, a fourth motor 104 is arranged at the bottom of the base 100. The fourth motor 104 is connected to a double-threaded screw 105. Two third sliders 106 are sleeved on the double-threaded screw 105. Forklift groove plates 107 are fixedly connected to the bottoms of the third sliders 106; the fourth motor 104 drives the double-threaded screw 105 to rotate, thereby driving the two third sliders 106 to move towards / away from each other along the double-threaded screw 105 to adjust the distance between the forklift groove plates 107 to facilitate lifting and transporting the pressure supply device by a forklift.
