Description

[0002] In the railway transportation industry, wheel set is one of the core components of railway freight car, and its surface coating quality is directly related to the durability, corrosion resistance and overall performance of the wheel set. With the rapid development of railway transportation and the continuous rise of safety and reliability requirements for freight cars, the traditional wheel set spraying process has been difficult to meet modern needs.

[0003] Traditional manual spraying wheel set has many drawbacks. First of all, its efficiency is extremely low, far from keeping up with the rhythm of large-scale maintenance and production of railway freight cars. The instability of manual operation makes the spraying quality uneven, and problems such as uneven coating thickness and poor surface finish frequently occur, which seriously weakens the protective ability of the wheel set in harsh railway operating environment, increases the wear and tear and maintenance frequency of the wheel set, increases the operating cost and hides safety hazards.

[0004] Furthermore, the traditional spraying equipment and site layout lack systematic planning. The airflow organization in the spraying area is chaotic, and the paint mist diffusion is difficult to control, resulting in a large amount of paint mist adhering to the equipment and workshop walls, which not only destroys the clean environment of the workshop, but also forms potential safety hazards such as fire, explosion and other accident risks. In addition, the paint supply system management is extensive, and uneven paint mixing directly affects the coating quality, while the lack of effective cleaning means for the spray head makes it prone to blockage, seriously interfering with the continuity and stability of the spraying operation and reducing production efficiency.

[0060] Working principle of the utility model:

[0061] In actual application, the wheel set 7 enters the spraying room 1 along the guide rail 11 through the feeding port. First, the blocking wheel driving cylinder 322 of the blocking wheel mechanism 32 is actuated, the blocking wheel 323 is driven to rotate through the rotating arm 324, and the wheel set 7 is fixed at a specified position below the spraying mechanism 2.

[0062] Subsequently, the spraying mechanism 2 is started. A plurality of nozzles are moved horizontally under the action of the nozzle transverse moving device 23 according to a preset spraying program, the transverse moving motor 236 drives the transverse moving gear 235 to rotate on the transverse moving rack 234, drives the transverse moving mounting plate 231 and the nozzles to move horizontally along the transverse moving guide rail 232, and the built-in lifting device of the nozzles is lifted in the vertical direction according to the shape and size of the wheel set 7, so that the wheel set 7 is sprayed accurately in all directions.

[0063] During the spraying process, the pneumatic diaphragm pump of the paint supply system 4 continuously stirs the paint, and the paint is delivered to the nozzles through the pipeline. The air conditioning air inlet system 5 sends air to the spraying room 1 through the air blower set 51, maintains a good airflow environment in the room, and makes the paint mist uniformly diffuse. The running driving motor 316 of the running device 31 works, drives the running driving gear 314 to rotate, drives the running driven gear 315 and the V-shaped running main gear and the V-shaped running driven gear to rotate through the chain, and thus drives the wheel set 7 to stably rotate, so as to ensure that the paint uniformly covers the surface of the wheel set 7.

[0064] The exhaust gas generated by spraying is collected by the exhaust gas treatment system 6 through a pipeline, and after preliminary collection in the form of secondary adsorption, is transported to an external catalytic combustion device for treatment, and the treated exhaust gas is discharged through an external chimney, and the discharge reaches the environmental protection standard.

[0065] When the spraying operation is completed, the water tank of the paint supply system 4 automatically cleans the spray head, ready for the next spraying. At the same time, the blocking wheel driving cylinder 322 of the blocking wheel mechanism 32 is actuated again to push the wheel set 7 to the discharge port, completing the automatic spraying process of the entire wheel set 7, and then the spraying operation of the next wheel set 7 can be performed.

[0066] The wheel set automatic spraying system effectively solves the problems of low efficiency, unstable quality, poor environmental protection and the like existing in the traditional wheel set spraying mode, has a wide application prospect and remarkable economic and social benefits.
