Description

Technical Field

[0001] The invention relates to the technical field of railway freight car wheel set maintenance, in particular to an automatic wheel set spraying system. Background Art

[0002] In the railway transportation industry, wheelsets are one of the core components of railway freight cars, and the quality of their surface coating is directly related to the durability, corrosion resistance and overall performance of the wheelsets. With the rapid development of railway transportation and the continuous increase in the safety and reliability requirements for freight cars, the traditional wheelset spraying process can no longer meet modern needs.

[0003] Traditional manual spraying of wheelsets has many drawbacks. First, its efficiency is extremely low, far from keeping up with the pace of large-scale maintenance and production of railway freight cars. The instability of manual operation leads to uneven spraying quality, uneven coating thickness, poor surface finish and other problems, which seriously weaken the protection ability of wheelsets in harsh railway operating environments, increase the loss and maintenance frequency of wheelsets, increase operating costs and bury safety hazards.

[0004] From an environmental perspective, traditional spraying methods put great pressure on the environment. During the spraying process, a large amount of paint mist and exhaust gas are discharged into the atmosphere without restraint. The volatile organic compounds (VOCs) and other harmful components contained in them seriously pollute the air, posing a serious threat to the surrounding ecological environment and the health of residents. It also runs counter to the increasingly stringent environmental regulations, exposing companies to huge environmental risks and legal sanctions.

[0005] Furthermore, the traditional spraying equipment and site layout lack systematic planning. The airflow in the spraying area is chaotic, and the diffusion of paint mist is difficult to control, causing a large amount of paint mist to adhere to the equipment and workshop walls, which not only destroys the clean environment of the workshop, but also forms potential safety hazards due to the accumulation of paint mist, such as fire, explosion and other accidents. In addition, the paint supply system is managed extensively, and uneven mixing of paint directly affects the quality of the coating. The nozzle lacks effective cleaning methods and is prone to clogging, which seriously interferes with the continuity and stability of the spraying operation and reduces production efficiency.

[0006] To sum up, it is urgent to develop an automatic wheelset spraying system that can achieve efficient, high-precision, high-quality spraying operations and has complete environmental protection functions. This is of great significance for promoting the progress of railway freight car wheelset maintenance and production technology and improving the economic and environmental benefits of enterprises.

[0025] The present invention has the following beneficial effects:

[0026] Excellent spraying quality and efficiency: Multiple nozzles can be precisely positioned in the horizontal and vertical directions with the help of the coordinated operation of the nozzle transverse movement device and the built-in lifting device, perfectly adapting to wheelsets of different specifications, achieving a full range of high-precision spraying effects, significantly improving the uniformity and integrity of the coating, and making a qualitative leap in spraying quality and efficiency. The nozzle transverse movement device adopts a precision transmission design of motor-driven gear racks, combined with the stable guidance of the transverse guide rail slider, to ensure that the nozzle is accurately positioned and runs smoothly when moving horizontally, effectively reducing spraying deviations and providing a solid guarantee for high-quality spraying.

[0027] Reliable wheelset auxiliary function: The unique V-shaped driving wheel and driven wheel structure of the wheel runner, combined with the sprocket drive, can stably drive the wheelset to rotate at a uniform speed, ensuring that the paint sprayed by the spray gun evenly covers the surface of the wheelset, eliminating the phenomenon of missed spraying or uneven spraying.

The whole process has a high degree of automation and stable and reliable operation, which greatly improves production efficiency and reduces the risk of manual operation.

[0028] Excellent working environment and environmental protection characteristics: The air-conditioning intake system creates a stable airflow circulation for the spray room through the air supply unit, which helps to maintain a suitable temperature, humidity and air pressure environment in the room, promotes the good diffusion and sedimentation of paint mist, and reduces the adhesion of paint mist on the surface of the equipment, which is not only conducive to the normal operation of the equipment and the extension of its service life, but also provides a comfortable working environment for operators. The exhaust gas treatment system uses a secondary adsorption process to deeply treat the spray exhaust gas, which can effectively remove harmful substances such as volatile organic compounds (VOCs) in it, so that the exhaust gas emissions strictly meet the standards, greatly reducing the pollution to the surrounding environment, meeting the requirements of environmental protection regulations, and helping enterprises achieve sustainable development.

[0029] Durable and easy-to-maintain spray booth structure: The spray booth frame is welded with profiles, which has high strength and stability and can effectively withstand various stresses generated during equipment operation. The combination of composite insulation board and galvanized spray-coated steel plate not only gives the spray booth excellent insulation performance and reduces energy consumption, but also makes it have strong corrosion resistance and impact resistance, which can adapt to complex and changing industrial environments, significantly extend the service life of the spray booth, and reduce maintenance costs. The internal sewage grille plate is convenient for collecting paint residue and waste liquid generated during the spraying process, which is convenient for cleaning and maintenance, effectively keeping the interior of the spray booth clean and hygienic, and reducing the adverse effects of paint residue on equipment and spraying quality.

[0030] Stable paint supply system guarantee: The pneumatic diaphragm pump in the paint supply system can evenly stir the paint to ensure that the composition and concentration of the paint are always stable, so that the quality of the sprayed paint is constant, which effectively guarantees the spraying effect of the wheelset. The configuration of the clean water cylinder can automatically clean the nozzle after each spraying operation to prevent nozzle blockage and residual paint from interfering with the next spraying operation, extend the service life of the nozzle, reduce downtime caused by nozzle failure, and improve production efficiency.

During the spraying operation, the nozzle needs to frequently move laterally and vertically, which will generate various dynamic loads and vibrations. The spray frame 22 made of steel can effectively resist these loads and vibrations, ensure the position accuracy and stability of the nozzle during the movement, and thus ensure the uniformity and accuracy of the spraying.

[0061] Working principle of the present invention:

[0062] In actual application, the wheel set 7 enters the spraying room 1 through the feed port along the guide rail 11. First, the wheel stopper driving cylinder 322 of the wheel stopper mechanism 32 is actuated, and the wheel set 7 is fixed at a designated position below the spraying mechanism 2 by driving the stopper wheel 323 through the rotating arm 324.

[0063] Then, the spraying mechanism 2 is started. Under the action of the nozzle transverse movement device 23, according to the preset spraying program, the transverse movement motor 236 drives the transverse movement gear 235 to rotate on the transverse movement rack 234, driving the transverse movement mounting plate 231 and the nozzle to move transversely along the transverse movement guide rail 232. At the same time, the lifting device built into the nozzle makes the nozzle move up and down in the vertical direction according to the shape and size of the wheelset 7, so as to realize the precise spraying of the wheelset 7 in all directions.

[0064] During the spraying process, the pneumatic diaphragm pump of the paint supply system 4 continuously stirs the paint and delivers the paint to the spray head through the pipeline. The air conditioning intake system 5 supplies air to the spray room 1 through the air supply unit 51 to maintain a good air flow environment in the room and evenly diffuse the paint mist. The running-in drive motor 316 of the running wheel 31 works to drive the running-in drive gear 314 to rotate, and drives the running-in driven gear 315 and the V-type running-in driving wheel and the V-type running-in driven wheel to rotate through the chain, thereby driving the wheelset 7 to rotate stably, ensuring that the paint evenly covers the surface of the wheelset 7.

[0065] The waste gas generated by spraying is collected by the waste gas treatment system 6 through a pipeline, and after preliminary collection in the form of secondary adsorption, it is transported to an external catalytic combustion device for treatment. The treated waste gas is discharged through an external exhaust chimney, and the emissions meet environmental protection standards.

[0066] When the spraying operation is completed, the water tank of the paint supply system 4 automatically cleans the nozzle to prepare for the next spraying. At the same time, the wheel drive cylinder 322 of the wheel blocking mechanism 32 is activated again to push the wheel pair 7 to the discharge port, completing the automatic spraying process of the entire wheel pair 7, and then the next wheel pair 7 spraying operation can be carried out.

[0067] The automatic wheelset spraying system of the present invention effectively solves the problems of low efficiency, unstable quality, poor environmental protection, etc. in the traditional wheelset spraying method, and has broad application prospects and significant economic and social benefits.

Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
