The car body and underframe of the 4m3 bottom side dump car are made of Q235A, and their wear resistance, corrosion resistance and impact resistance are poor, especially the underframe, which often deforms during use, has a high repair rate and short service life. Therefore, in the design of 10m3 bottom side dump tramcar, the car body and underframe are made of 16Mn steel, and the structure is also improved accordingly. Compared with Q235A steel, the strength of 16Mn steel is increased by 50%, the atmospheric corrosion resistance is increased by 20-38%, and the low-temperature impact toughness is also superior, and the price is not expensive. Some manufacturers also use QJ50 and QJ70 rare earth steel plates to cover the underframe of tramcars. The service life is 1.5-2 times longer than that of 16Mn steel, but the price of this steel is expensive, which is applicable to mines with high requirements for wear resistance of tramcars; In addition, the car floor can also be overlaid with wear-resistant electrodes to improve its wear resistance. In the structural design of the underframe, two box shaped longitudinal main beams and transverse wheel support beams are used to form a rigid frame structure, which greatly enhances its strength, reduces deformation, not only reduces maintenance, but also extends the service life of the tramcar.
At present, there are many kinds of trams for ore transportation in domestic mines, and large and medium-sized mines tend to use bottom dump and bottom side dump trams for transportation. Compared with other types of tramcars, these two types of tramcars can realize continuous loading and unloading
Good morning, young friends! Next, the small editor is ready to explain the relevant contents of the single hydraulic prop for the small friends. The small friends are also deeply impressed with the single hydraulic prop. I still hope that this explanation will bring some gains to my friends1. For n
In order to make the hydraulic acrow props work stable, give full play to the efficiency of the equipment, and extend the service life, in addition to strictly complying with the operating procedures, it is necessary to strengthen daily maintenance.Precautions for maintenance and management of singl
