Description

TECHNICAL FIELD

[0001] The utility model relates to internal combustion engine technical field, namely a kind of internal combustion engine car air filter quick dismounting device. BACKGROUND

[0002] In prior art, diesel engine is used as the power source of internal combustion engine car, and its working state directly affects the exertion of locomotive power, and the direct cause of abnormal wear of piston and cylinder liner is the impurity in the intake air, and air filter plays a vital role in the quality of intake air.

[0003] GK1C type internal combustion engine car air filter is composed of three stages, the first stage is V-shaped screen, which filters out leaves, paper sheets, plastic bags and other large impurities.

[0004] The second stage is a one-piece multi-cyclone tube type coarse filter composed of 54 straight-through cyclone tubes, and when air flows through the cyclone tubes at high speed, dust is thrown along the wall of the cyclone tubes by cyclone centrifugal action and is concentrated in the lower dust discharge hopper.

[0005] The third stage is a steel mesh type paper filter, and when air passes through the paper filter, dust is filtered out by the paper filter element, ensuring that clean air enters the cylinder for combustion. According to the requirements, the paper filter is blown once a month, and during the blowing, the attendant needs to use a crowbar to push against the center position of the mounting plate, and then loosen the nuts of the mounting plate to the lowest position, so that the paper filter can be removed. The maintenance time is long, and at the same time, when loosening the nuts on the inner side of the mounting plate, the arm needs to be deep, and personal injury is easily caused due to improper operation. SUMMARY

[0006] The utility model aims at the above-mentioned insufficient and provides a kind of quick dismounting air filter, and ensures the internal combustion engine car air filter quick dismounting device of personal safety.

[0007] The technical solution of the utility model is as follows: a kind of internal combustion engine car air filter quick dismounting device, lifting platform can be fixed or mobile installation in the upper side of two-stage multi-cyclone tube type coarse filter, and the top of lifting platform is connected with the mounting plate below air filter;The lifting platform is fixed support installed above two-stage multi-cyclone tube type coarse filter, folding rod hinged structure is used between fixed support, and there is screw drive shaft in the middle;Limit stop is fixed on the upper side of mounting plate and connected with box body.

[0008] There are screw rods on the lower side of filter mounting plate, and there are fastening nuts on the screw rods.

[0009] The utility model has the advantages that: the lifting platform installed above two-stage multi-cyclone tube type coarse filter can quickly adjust the rising or falling of air filter mounting plate, which facilitates the replacement of air filter, improves the maintenance efficiency and ensures personal safety.

[0010] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 is the structural diagram of the present application.

[0012] Figure 2 is Figure 1 is the left view structural diagram of the lifting platform. DETAILED DESCRIPTION

[0013] Referring to Figure 1 , 2 , the names of the parts are as follows: 1, lifting platform, 2, air cleaner mounting plate, 3, limit stop, 4, screw drive shaft, 5, two-stage multi-swirl pipe type coarse filter, 6, box body, 7, air cleaner (paper filter), 8, nut.

[0014] Referring to Figure 1 , 2 , a quick dismounting and mounting device for an air cleaner of an internal combustion engine vehicle, the lifting platform 1 is fixedly or movably installed above the two-stage multi-swirl pipe type coarse filter 5, and the top is connected below the air cleaner 7 mounting plate 2, which can stably support the filter mounting plate 2 and prevent personal injury, and the lifting platform 1 is lifted or lowered by rotating the screw drive shaft 4 by hand or electric tool, thereby shortening the time for replacing the air cleaner 7; the lifting platform 1 is a scissor type lifting machine, which is fixedly installed above the two-stage multi-swirl pipe type coarse filter 5 and has a folding rod hinged structure between the fixed supports 9, can stably support the filter mounting plate 2, has a screw drive shaft 4 in the middle, and can quickly adjust the air cleaner mounting plate 2 to rise or fall by rotating the screw drive shaft 4 by hand or electric tool, thereby facilitating the replacement of the air cleaner 7, improving the safety degree of the maintenance personnel during work, and improving the maintenance efficiency; the limit stop 3 is fixed above the mounting plate 2 and connected with the box body 6, which prevents the air cleaner 7 from being damaged due to excessive tightening of the lifting platform 1. The attendant can safely tighten the nut 8 inside the filter mounting plate 2, thereby preventing personal injury.

[0015] The lifting platform 1 can be divided into a hydraulic lifting machine and an electric lifting machine according to the needs of the user. The lifting platform 1 is driven by hand or electric tool, which can quickly adjust the air cleaner mounting plate 2 to rise or fall, thereby facilitating the replacement of the air cleaner 7 and improving the maintenance efficiency.
