Open can type six-axis molten iron vehicle with load of 140 to 160t

Abstract

The invention discloses a six-axis open can molten iron vehicle with load of 140 to 160t. The molten iron vehicle is characterized in that: the wheel set of a bogie is a special wheel set of the molten iron vehicle, an axle of the special wheel set of the molten iron vehicle is borne by two dual-aligning bearings arranged in parallel, and a space ring is arranged between the two dual-aligning bearings. A connecting device is arranged between the bogie and a vehicle body, and the connecting device encircles a connecting center disc of the bogie and the vehicle body and is arranged in parallel horizontal gaps of the vehicle body and the bogie. The special wheel set of the molten iron vehicle has good aligning performance, and can compensate coaxial error caused by bending deformation of theaxle, bear high axial load and improve the small-curve passing capability of the molten iron vehicle; and the axle load can reach 43t. The connecting device is non-contact, and does not affect the relative rotation between the vehicle body and the bogie; and when the vehicle needs rescue or the vehicle derails and needs reset, the vehicle body carrying the bogie is integrally hoisted under the action of other operating equipment so as to facilitate the operations such as vehicle maintenance, rescue and the like.

Description

technical field [0001] The invention relates to a special molten iron transportation vehicle for iron and steel enterprises, which is used for the transportation of molten iron inside the iron and steel enterprises. Background technique [0002] In the prior art, the transportation of molten iron in the iron and steel industry generally adopts several forms of molten iron vehicles such as open tank type molten iron vehicles and torpedo tank vehicles. The basic requirements of hot metal cars, all iron and steel enterprises are carrying out the renovation of hot metal cars. [0003] In the prior art, the capacity of open-top tank-type molten iron trucks is relatively small, generally 30t, 50t, 65t, and 100t of loaded molten iron, which is far from meeting the needs of iron and steel enterprises; the reason why the weight of open-top tank-type molten iron vehicles is difficult to increase is that: [0004] 1. Generally, only one bogie can be arranged on the front and back of t...

AI Technical Summary

Problems solved by technology

[0005] 2. Since the open tank type molten iron car usually adopts a three-piece cast steel bogie, the spring is above the side frame, the unsprung weight is relatively large, the dynamic performance of the whole vehicle is poor, the ability to pass through the curve is poor, and the rim wear is serious. The side frame and bolster have insufficient lateral anti-diamond rigidity, which is not suitable for transportation on small curved transportation lines within the enterprise

[0006] 3. Usually, the car body and the bogie are coaxially connected only by the central pin set in the center of the bogie, allowing relative rotational movement between the two, and there is no vertical connection between the car body and the bogie up and down method, once an accident such as falling off the road occurs, the car body and the bogie cannot be hoisted and reset as a whole, and the bogie can only be reset by other methods after the car body is hoisted, the operation is cumbersome, the equipment and site requirements are high, and the time is long

[0007] 4. Generally, the open tank type molten iron car does not use the wind hand brake device, and the operation safety is poor

[0008] Due to the defects of the above structure, it is difficult to increase the overall load capacity of the special transport vehicle such as the open tank type molten iron car, the running speed is low, the running performance is poor, and the safety performance is difficult to guarantee, so further improvement is needed
