Universal balance weight for railway tank car

Abstract

The invention relates to a universal balance weight for a railway tank car. The balance weight is characterized by comprising an inner balance weight and an outer balance weight which can be installed in a tank car manhole, wherein the outer balance weight is provided with a connecting part which can movably connect and fix the balance weight on the tank car. By adopting a structure combining the inner balance weight and the outer balance weight, the weight requirement on a required balance weight can be reduced in use, and therefore, the balance weight can be made of common steel and the cost is reduced greatly. In the invention, since the balance weight is fixed on the tank car in a movable connected way, the balance weight rotates together with the tank car without impact; and meanwhile, the universal balance weight is also provided with a locking device used for further indenting the inner balance weight and the outer balance weight, thereby greatly improving the use safety of the universal balance weight. In addition, the universal balance weight is also provided with adjustable balance weights, the weight of the universal balance weight can be increased or decreased easily by increasing or reducing the adjustable balance weights according to field conditions and the requirement of different unbalanced weights.

Description

technical field [0001] The invention relates to a general-purpose counterweight specially designed for overcoming the influence of tank body eccentricity on tank body rotation in the field of railway tank car manufacturing, and is also suitable for the manufacture of large-diameter and large eccentricity tank containers in other industries. Background technique [0002] During the manufacturing process of the tank body of the railway tank car, the tank body needs to be rotated for a whole circle to facilitate the assembly and welding of various parts. Because the tank body has a very large weight after the pillow structure is welded, the ordinary can transfer machine cannot rotate the heavy tank body, so it is necessary to add a counterweight to keep the tank body balanced, so as to realize the rotation of the heavy tank body. [0003] At present, various railway factories generally use general-purpose can transfer devices and counterweights to realize the rotation of heavy ...
