Description

A spraying device for cleaning the coupling of EMUs

technical field

The utility model relates to a spraying device used for cleaning the coupling of an EMU, which belongs to the field of cleaning equipment.

Background technique

CRH2A/B/C1/E EMUs use WN couplings, and CRH2C Phase II and 380A/L EMUs use couplings produced by ESCO in Belgium. Clean the outer cylinder, pinion and other components. At present, the cleaning method of EMU couplings is mostly manual cleaning, which has low efficiency, and some parts of the inner cavity are not easy to be cleaned effectively, resulting in poor cleaning effect; cleaning with an ultrasonic cleaning machine is relatively expensive. There are patents at home and abroad that use spraying to clean similar mechanical parts. For example, the Chinese utility model patent No. CN205253629U discloses a "machine parts cleaning machine". This cleaning machine is equipped with a series of nozzles on the top. This kind of nozzle arrangement can only complete the cleaning of one part of the inner surface or the outer surface in one clamping, and we urgently need a one-time clamping to complete the effective cleaning of the inner and outer surfaces of the coupling.

Utility model content

In view of the above problems, the utility model aims to design a spraying device for cleaning the couplings of EMUs, so as to realize the effective cleaning of the inner and outer surfaces of the couplings once the couplings are placed.

The technical scheme adopted in the utility model:

A spraying device used for cleaning the couplings of EMUs. The spraying device includes a flange plate, a nozzle pipe in the middle and a plurality of uniformly distributed nozzle pipes. The upper end of the pipe is connected to the large threaded hole through a pipe joint, and a plurality of evenly distributed small threaded holes are arranged on the edge of the bottom surface of the flange. The lower end is respectively provided with a sealing device for sealing; the middle nozzle pipe is provided with a plurality of series of nozzle holes from top to bottom, and each series of nozzle holes is composed of nozzle holes distributed uniformly along the circumference of the middle nozzle pipe. It is inclined to the axis of the central nozzle to form a set angle; the uniformly distributed nozzle is provided with a plurality of series of nozzle holes from top to bottom, and each series of nozzle hole combinations corresponds to one nozzle hole on all uniformly distributed nozzles. The axes of each nozzle hole are inclined to form a set angle with the axis of the middle nozzle.

Further, the lower ends of the middle spray pipe and the uniform spray pipe are sealed by oil plug pads and oil plugs.

Further, preferably, the axes of the nozzle holes of the middle nozzle are respectively separated from the axis of the middle nozzle, so that the cleaning liquid can form a vortex on the surface of the workpiece.

Further, preferably, the axis of each nozzle hole of the uniformly distributed nozzle is separated from the axis of the middle nozzle, so that the cleaning liquid can form a vortex on the surface of the workpiece.

Further, the lower end of the uniformly distributed nozzle is set to bend inward.

The beneficial effects of the utility model are:

The spraying device developed by the utility model is used for cleaning the coupling, and it is installed on the reciprocating mechanism to move up and down, which can effectively clean the inner and outer surfaces of the coupling of the EMU at one time, improve the cleaning efficiency, and has the advantages of easy operation, The cleaning effect is good, the labor force of the workers is reduced, the cleaning cost is reduced, and the working environment of the workers is improved.
