In the huge system of modern industrial production, the sand blasting room, as a key link in metal surface treatment, bears the responsibility of removing impurities and oxidised skin on the surface of the workpiece, and laying the foundation for subsequent spraying and painting processes. And rail transfer car for sandblasting rooms, as the core equipment for material transport in this link, the performance of its equipment directly affects the production efficiency and the service life of the equipment.
The working environment in a sandblasting room is extremely special, filled with a large amount of flying sand and grit. These fine particles are pervasive, will not only accelerate the wear and tear of the transmission device, but also may penetrate the automatic control system, resulting in circuit short-circuit and other serious malfunctions. Compared with a simple spraying workshop and a baking paint room, the sand blasting room has more stringent protection requirements for electric rail transfer cart.
Because of the existence of thinner and other flammable and explosive substances in the spraying workshop, electric rail transfer cart is required to have explosion-proof performance; the high temperature environment of the paint baking room requires rail-guided transport systems to do a good job of insulation and heat preservation, and heat dissipation treatment of all components. And in the complete production line, including sand blasting – spraying – painting, electric transfer cart on rail must simultaneously meet a variety of complex work requirements, and become an ‘all-round player’ in industrial production.
The anti-fouling design scheme adopted by the sand blasting room rail transfer trolley is the key to differentiating it from the ordinary rail transfer trolley. Through the special sealing structure and protective coating, it effectively blocks the wind and sand from entering the internal of the transmission device and the automatic control system.
For example, in key parts such as bearings, gearboxes, etc., multi-layer sealing rings and dust covers are used to form multiple protective barriers, which ensure stable operation of the equipment even in the sandy and windy working environment, and significantly reduce the equipment failure rate and maintenance costs.
The frames of rail transfer trolley are mainly welded by channel steel, and the steel plates are especially thickened in the key parts of transfer car body, such as the motor mounting place and load-bearing pivot point etc. This design gives rail transfer trolley body a strong anti-dumping resistance. This design gives transfer car body a strong resistance to pressure and impact, not only can it firmly carry the transported materials, but also effectively protect the circuit equipment and transmission devices above transfer car body. Even in the process of frequent starting and braking, it can also avoid damage to the internal equipment due to vibration and collision, and prolong the overall service life of rail transfer trolley.
The unique hollow structure design of rail transfer cart shows the perfect combination of wisdom and practicality. During the sand blasting operation, the flying grit can naturally fall through the gap on the surface of rail transfer cart, and the collection device can directly recycle and reuse it. This design not only reduces the waste of gravel, reduces the production cost, but also avoids the obstruction caused by the accumulation of gravel on the operation of rail transfer cart, which is also in line with the industrial development trend of green production and resource recycling.
In order to guarantee the personal safety of the operators, rail transfer cart for the sand blasting room adopts a remote control operation mode. The operator does not need to be in the sand blasting room, and can precisely control the forward, backward, steering, and other actions of rail car through the remote control. The advanced remote control system is characterised by stable signals and strong anti-interference ability, which ensures the accurate transmission of operating instructions even in a complex electromagnetic environment, and effectively avoids potential injuries to the operators due to close contact with the sand blasting operation.
In the spraying workshop, self propelled transporter is equipped with professional explosion-proof devices. From the motor, electrical components to transfer car body shell, all are made of explosion-proof materials and processes. The explosion-proof motor can prevent electric sparks from being generated, avoiding the danger of explosion; the explosion-proof shell can effectively block the flame and energy generated by the explosion, ensuring the safe production of the entire spraying workshop.
Facing the high temperature environment of 80 degrees or even higher in the paint booth, all the components of self propelled transporter have been given special heat insulation and thermal insulation treatment. High-temperature-resistant heat insulation materials are used to wrap key components, such as motors, controllers, etc., to prevent high temperatures from affecting the performance of the equipment. At the same time, reasonable heat dissipation channels are designed to emit the heat generated by the equipment’s operation in time, realizing the perfect balance between heat insulation and heat dissipation to ensure rail-guided transport systems work continuously and stably under a high-temperature environment.
In the multi-workshop integrated assembly line, the sand blasting room rail cart integrates a variety of protective functions such as anti-fouling, anti-explosion, and heat insulation. Whether it is in the sandblasting room filled with wind and sand, or a flammable and explosive spraying workshop, or a high-temperature baking paint booth, it can easily cope with, seamlessly connect the various production links, to ensure the efficient operation of the entire production line, and become an indispensable and important equipment in industrial production.
Enterprises in the purchase of sand blasting room rail transfer carts should focus on their anti-fouling, structure, operation, and other core advantages.
Check whether the anti-fouling design is tight and whether the sealing performance is good.
Observe whether the structure of transfer car body is solid and whether the thickness of the steel plate in the key parts is up to standard.
Test the sensitivity and stability of the remote control system. At the same time, it is necessary to combine the specific environmental requirements of their own production workshops, such as whether it involves spraying, baking paint, and other links, to choose rail transfer trolleys with corresponding protective functions, to ensure that the equipment is perfectly adapted to the production environment.
