Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aero-engine test running, in particular, to an aero-engine test running lubricating oil filling equipment. BACKGROUND

[0002] The information provided in this section is for the purpose of generally presenting the background of the application. To the extent that the descriptions in this section describe the work of the inventors, and to the extent that the descriptions in this section are not considered prior art by themselves or in combination with other prior art, they are not an admission that the work described belongs to the prior art.

[0003] When the aero-engine is tested on the test bed, the engine is first installed on the test bed of the test bed, and after the connection of various pipeline lines, the lubricating oil is filled.

[0004] The lubricating oil is a third-class flammable material, and for safety reasons, it is not allowed to directly store the oil tank containing lubricating oil and other containers on the test bed of the test bed. At the same time, due to the large number of test bed test related equipment and facilities on the test bed, the space on the test bed is usually not sufficient. Please refer to the attached drawings of the specification Figure 1 , which is a schematic diagram of the layout of the test bed in the prior art. At present, the lubricating oil is filled on the test bed, and the operator takes the lubricating oil from the test bed lubricating oil room, transports it to the outside of the test room, and then uses the manual oil tank to climb the test bed rack to fill the lubricating oil. Please refer to the attached drawings of the specification Figure 2 , which is a schematic diagram of the layout of the test bed in the prior art. The operator needs to climb the steel ladder of the test bed to operate.

[0005] At present, the lubricating oil is filled on the test bed, and the traditional manual lubricating oil tank is used to climb the test bed rack to fill the lubricating oil. There are several shortcomings:

[0006] 1. There is a safety risk. During the transportation and lubricating oil filling process, some lubricating oil will inevitably splash and fall on the test bed, and the lubricating oil remaining on the test bed will have a flammable safety risk;

[0007] 2. There is a risk of misoperation. When there is residual lubricating oil on the test bed, the operator may also fall due to the slippery surface of the test bed, and misoperate the equipment and facilities on the test bed;

[0008] 3. The working efficiency of lubricating oil filling is low. The operator needs to transport the lubricating oil from the test bed lubricating oil room to the test room door, and then lift it to the test bed to fill the lubricating oil. The operation time is long, the production efficiency is low, and the production efficiency of the test bed is restricted.

[0009] It should be noted that the information disclosed in the above background section is only used to enhance the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those skilled in the art. SUMMARY

[0062] It can be understood that the elevatable limiting support frame 24 can be used to support and limit the front barrel of the oil gun 1, facilitating the taking and storing of the oil gun 1. In order to enhance the limiting stability of the front barrel, the clamping members 251 hinged on the limiting side plates 242 are used to press and limit the front barrel, ensuring the stability of the limiting and avoiding the front barrel from falling off and other phenomena.

[0063] Optionally, the telescopic rod assembly 22 comprises a telescopic inner rod 221 and a telescopic outer rod 222, the telescopic outer rod 222 being telescopically sleeved outside the telescopic inner rod 221 and being lockable and fixed by a locking nut.

The clamping member 251 is hinged to the limiting side plate 242 through a torsional spring.

[0065] Preferably, as shown in Figures 11-14 The front stock mechanism 2 further comprises a pushing assembly 23, two rotating assemblies 26, a first shielding member 27 and a second shielding member 28. The two rotating assemblies 26 are hinged to the outer walls of the limiting side plates 242 on both sides, respectively. The pushing assembly 23 is movably arranged on the limiting side plate 242. The first end of the pushing assembly 23 is hinged to the bottom of the clamping member 251, and the second end of the pushing assembly 23 is hinged to the bottom of the rotating assembly 26. The first shielding member 27 is connected to the top of the rotating assembly 26 on one side, and the second shielding member 28 is connected to the top of the rotating assembly 26 on the other side. The clamping members 251 on both sides are used to be pressed downward by the front barrel to rotate, so as to drive the pushing assemblies 23 on both sides to move outward along the vertical direction of the limiting side plate 242 synchronously, and then drive the rotating assemblies 26 on both sides to rotate, so as to drive the first shielding member 27 and the second shielding member 28 to abut and close, respectively, and shield and protect the inlet of the front barrel.

The plurality of safety pins 35 are used to pass through the respective safety holes 34 to clamp the trigger of the oil gun 1.

[0074] It can be understood that the rear stock mechanism 3 cooperates with the front stock mechanism 2 to support and limit the oil gun 1, and keep the front barrel oriented and clamped. The stock bottom plate 31 is fixed in the lower hanging bin 301, and the inner side of the stock bottom plate 31 mainly plays a role in supporting the bottom of the oil gun 1. The distance between the side support plates 32 on both sides is set to be 2-3mm larger than the width of the oil gun 1, which facilitates the placement of the oil gun 1 and clamps the oil gun 1 through the side support plates 32 on both sides to prevent the oil gun 1 from tilting left and right. The side support plates 32 are provided with a plurality of safety holes 34. The safety pins 35 are inserted into the safety holes 34, which can lock the oil gun 1 and clamp the trigger of the oil gun 1 to avoid the risk of oil spouting caused by misoperation. The tail wall 33 supports the rear side of the protective edge of the oil gun trigger. The oil inlet hose of the oil gun 1 passes through the upper end of the tail wall 33 and is communicated with the vertically curved hose 303 through the limiting perforation of the lower hanging bin 301.
