Description

Technical Field

[0002] Steel mill vehicles are special vehicles used in the internal and external transportation process of steel mills, mainly used to transport various steel materials, such as steel billets, steel coils, etc. Most of the existing steel mill vehicles are shown in the scheme disclosed in the Chinese patent with publication number CN219687171U and the name of a multi-in-one steel coil special vehicle chassis. Its steering generally adopts a traditional steering axle structure, and the steering angle of the traditional steering axle structure is limited and the steering angle control accuracy is insufficient. When the road in the operation scene of the steel mill vehicle is relatively narrow and steering is inconvenient, the use of traditional steering axles cannot meet the use requirements of the steel mill vehicle in operating scenes that require high control of steering angles and steering accuracy. In addition, for use scenarios with lower carrying capacity requirements, if a five-axle chassis such as the one disclosed in the Chinese patent with publication number CN219687171U and the name of a multi-in-one steel coil special vehicle chassis is adopted, it also leads to an increase in the cost of construction.

[0029] Two rotating devices 11 are distributed on the lower side of the chassis frame 10; an axle 12 is provided at the bottom of each rotating device 11; the rotating device 11 includes but is not limited to the use of a rotating bearing; an axle 12 is provided at the bottom of the output end of the rotating device 11; a driving device is provided at the input end of the rotating device 11, and the driving device includes but is not limited to a motor, a cylinder, an oil cylinder, etc.; the driving device drives the input end of the rotating device 11 to rotate, thereby driving the output end of the rotating device 11 to rotate, thereby driving the axle 12 connected to the output end to rotate to achieve steering; one or more of the axles 12 are drive axle structures to drive the vehicle to travel.

[0030] The new double-rotating single-bridge steel mill vehicle chassis structure provided in this embodiment replaces the traditional steering axle structure with a rotating device 11, and can perform more precise steering angle control when turning; through the structure of the cooperation of the two rotating devices 11, the turning radius can be reduced when turning, thereby ensuring that the vehicle can turn safely in narrow roads in the operating scenario; and, through the single axle 12 at the bottom of the rotating device 11, the number of axles 12 is reduced compared to the structure with multiple axles, thereby reducing the production cost of the chassis structure. The new double-rotating single-bridge steel mill vehicle chassis structure provided in this embodiment of the utility model can enable the steel mill vehicle to drive safely and turn flexibly on narrow roads with a small turning radius; it can be used in steel mill transportation scenarios with smaller carrying capacity requirements.

[0032] The oil cylinder 14 drives the input end of the rotating device 11 to rotate, thereby driving the output end of the rotating device 11 to drive a connected axle 12 to turn.

[0033] When implementing it, Figure 2 As shown, oil cylinders 14 are provided on both sides of the input end of the rotary device 11; the output end of the rotary device 11 is connected to an axle 12; the oil cylinder 14 drives the input end of the rotary device 11 to rotate, thereby driving the output end of the rotary device 11 to drive the connected axle 12 to turn.
