In addition, the three-dimensional spatial dimensions including length, width and depth should be included in actual manufacture.

[0028] Referring to Figures 1-4 For one embodiment of the present application, a portable tracked vehicle field oil sprayer detection tool is provided, which comprises an oil injection tool 1 and an oil sprayer 2, and a detection box 3 covering the spraying area of the oil sprayer 2 is arranged below the oil sprayer 2, a bracket 31 is rotatably arranged in the detection box 3, the bracket 31 is composed of a placing rack located inside the detection box 3 and a push rod slidingly arranged at the bottom of the detection box 3, the placing rack is arranged radially from the center to the periphery, the cross section of the push rod is in a prismatic shape, a spring 32 is slidingly arranged outside the push rod, and the placing rack is elastically connected with the detection box 3 through the spring 32.

[0029] As shown in Figure 2 The oil injection tool 1 is composed of a three-way joint 11, a conversion joint 12, a shockproof pressure gauge 13 and an oil pipe 14, the conversion joint 12, the shockproof pressure gauge 13 and the oil pipe 14 are respectively installed on the three ports of the three-way joint 11, the conversion joint 12 is in communication with the oil inlet of the oil sprayer 2, the conversion joint 12 can be replaced according to different interfaces of the oil sprayer 2, and the conversion joint 12 can meet the repair requirements of different models of oil sprayers 2 within a certain range, and the oil pipe 14 is used for external connection of an oil pump.

[0030] It should be noted that the oil injection tool 1 has the characteristics of independent carrying, and can carry out oil injection pressure detection work on the oil injector 2. Compared with the overall equipment, its structure is more simple, and can be quickly stored in the tracked vehicle to facilitate carrying. Moreover, the oil injection tool 1 is small in size and light in weight, meets the carrying standard, and occupies a very small storage space in the tracked vehicle, greatly improving the carrying convenience.

[0031] When the oil injector 2 can maintain the standard oil injection pressure in the steady pressure working condition, but the injection form appears abnormal atomization phenomenon, it will have serious influence on the tracked vehicle in many aspects. From the power performance aspect, the abnormal jet or uneven distribution of oil mist particles will make the fuel unable to fully and uniformly mix with air in the engine cylinder. This will lead to insufficient and unstable combustion process, engine output power reduction, insufficient power of the tracked vehicle during driving, and influence on its mobility, for example, it may not be able to quickly cross complex terrain, the field generator set power generation efficiency is reduced, and it is difficult to ensure the normal operation of the electrical equipment. At this time, it is necessary to detect the atomization quality of the oil injector 2.

[0032] The bracket 31 is placed with the oil shedding paper 4, and the surface of the oil shedding paper 4 is perpendicular to the injection direction of the oil injector 2. The oil mist sprayed by the oil injector 2 in a single injection can be distributed on the surface of the oil shedding paper 4 below, so that the detection personnel can intuitively judge the atomization quality of the oil injector 2, so as to detect the phenomenon that the oil injector 2 has normal oil pressure and abnormal injection form, and improve the detection effect.

[0033] The detection box 3 is provided with a protective cover 5 which can slide axially along the detection box 3. The protective cover 5 is made of transparent material, such as transparent acrylic plate. The bottom of the detection box 3 is symmetrically fixed with two slide rods 7 which slide through the protective cover 5. The slide rods 7 are provided with springs 71, and the top ends of the springs 71 are elastically connected with the bottom surface of the protective cover 5. The springs 71 are in a compressed state, and when the upper half of the protective cover 5 extends to the outside of the oil injector 2, an anti-interference area between the oil injector 2 and the oil shedding paper 4 is formed in the protective cover 5.

[0034] The bottom of the detection box 3 is hinged with a lever 6. The short arm of the lever 6 is located on the downward movement path of the protective cover 5, and the bottom end of the bracket 31 is located on the rotation path of the long arm of the lever 6. The hinge position of the lever 6 is provided with a stop 61 near the upper side of the short arm. When the top surface of the short arm of the lever 6 is in contact with the stop 61, the lever 6 is in a horizontal state, and the long arm of the lever 6 is in contact with the bottom end of the push rod.

[0035] When the protective cover 5 is lowered to press the lever 6, the bottom end of the bracket 31 is pushed upward by the lever 6, and when the upper surface of the protective cover 5 is lower than the upper surface of the detection box 3, the oil shedding paper 4 is lifted out of the detection box 3. At this time, the detection personnel can quickly replace the oil shedding paper 4.

[0036] The stand 8 can be fixed on the oil injection tool 1 by bolts, and is in sliding connection with the detection box 3. A threaded rod 81 is arranged on the stand 8 and is in rotational connection with the bottom end of the detection box 3. By rotating the threaded rod 81, the detection box 3 can be pushed down, so as to adjust the distance between the oil-repellent paper 4 and the oil sprayer 2.

[0037] In addition, the distance between the oil-repellent paper 4 and the oil sprayer 2 should be kept at 10-15 cm during the initial detection. After the single detection, the distance is adjusted to 5 cm for the second detection. By repeating the operation, the distribution of the oil mist sprayed by the oil sprayer 2 at different positions can be obtained, which is convenient for the detection personnel to observe the spray quality of the oil sprayer 2, so as to more accurately evaluate the performance of the oil sprayer 2.

[0038] The stand 8 and the detection box 3 are integrated, and the main function is to expand the technology on the basis of the oil injection tool 1, so as to detect other parameters of the oil sprayer 2 (such as atomization quality or needle valve tightness). In the idle state, the combination of the stand 8 and the detection box 3 is separated from the oil injection tool 1, which greatly improves the carrying convenience, and is more easily stored in the tracked vehicle, so as to quickly take and carry out comprehensive detection of the oil sprayer 2 in complex field environment, facilitate the repair operation in the field conditions, and ensure the completion of the tracked vehicle repair task in a short time, so that the tracked vehicle can be restored to normal use state in a short time.

[0039] Working principle: when the oil sprayer 2 used by the tracked vehicle fails, it is first disassembled and connected through the conversion joint 12, and the oil sprayer 2 is powered by the external power supply. When the oil pipe 14 is connected to the oil pump, the oil injection tool 1 can be used to inject oil into the oil sprayer 2. At this time, the oil injection pressure of the oil sprayer 2 can be detected by reading the reading of the shockproof pressure gauge 13.

[0040] Part of the fuel injector 2 in the steady state can maintain the standard injection pressure, but its injection pattern has appeared abnormal atomization phenomenon. The specific performance is that the oil beam presents non-normal jet characteristics or uneven distribution of oil mist particles, etc. Typical fault signs, the atomization quality needs to be detected, at this time, the stand 8 needs to be installed on the oil injection tool 1, and the detection box 3 is located directly below the fuel injector 2, at this time, the oil mist sprayed by the fuel injector 2 can fall on the oil absorbing paper 4 below, the operator can observe the distribution of oil points on the oil absorbing paper 4 through the protective cover 5, whether there is non-normal jet characteristics or uneven distribution of oil mist particles, after observation, the protective cover 5 is pulled down, the upper surface of the protective cover 5 is moved below the upper surface of the detection box 3, the top opening of the detection box 3 is exposed, and in the process, the protective cover 5 will squeeze the lever 6, the lever 6 will push the bracket 31 up after rotating, so that the oil absorbing paper 4 is lifted to the outside of the detection box 3, at this time, the detection personnel can replace the oil absorbing paper 4, after replacement, the protective cover 5 is loosened, the protective cover 5 is reset under the elastic force of the spring two 71, the bracket 31 drives the oil absorbing paper 4 to reset under the elastic force of the spring one 32, then the screw rod 81 is twisted, the gap between the detection box 3 and the fuel injector 2 is adjusted downward, and then the distribution of the oil mist is detected, and the above process is repeated to obtain the atomization quality of the fuel injector 2, and the result error is reduced.

[0041] At the same time, when the needle valve tightness of the fuel injector 2 is detected, only the oil droplets on the surface of the oil injection port position and the oil absorbing paper 4 in the static state of the fuel injector 2 need to be observed.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalent, without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
