Description

Open wagon side-opening correcting device Technical Field The invention relates to the technical field of railway transportation, in particular to a side-opening correction device for an open wagon. Background The open wagon is one kind of wagon and features no cover and four side plates, which have side door capable of being opened to facilitate unloading cargo. The open wagon is mainly used for conveying large cargoes such as coal, ore, mineral materials, wood, steel and the like, and can also be used for conveying mechanical equipment with small weight, so that the open wagon has great universality, the maximum number of open wagon is formed in a wagon, the number of open wagon is about 30 ten thousand in the whole country, and the open wagon accounts for more than 50% of the total number of the wagon. However, in the production and manufacturing process of the side-opening door of the open wagon, the welding part can be deformed, the deformed structure is generally in a semi-arc shape, two measures for solving the problems in the prior art are adopted, one measure is to perform thermal correction by adopting a flame heating method after the side-opening door is loaded, and the other measure is to perform mechanical correction of the side-opening door on hydraulic equipment (such as a four-column press) before the loading of the side-opening door after the side-opening door is produced. Flame heating correction is a common metal surface treatment method, and based on the characteristics of thermal expansion and contraction of metal, the deformed metal is corrected by adopting a flame local heating method, for example, when a concave or convex part exists on the surface of the metal, the convex part can be heated by flame to cause thermal expansion, and then the convex part is contracted by cooling treatment, so that the correction effect is achieved. The method has the advantages that the device is simple, for example, an oxygen-acetylene bottle is connected with a flame nozzle through a leather hose, special large-scale mechanical equipment is not needed, the use is convenient and flexible, the cost is low, the requirement on the experience skill of an operator is high, the correction process is required to be judged by the operator through experience, the safety risk coefficient of an operation site is high, and meanwhile, after heat treatment, the internal structure of the metal can be correspondingly changed, so that the mechanical property of a material of a heating part is reduced. The hydraulic equipment correction is to achieve the purpose of deformation correction through a mode of pressing the metal plates, for example, the deformed door plates are conveyed to a door plate shaping hydraulic press die, and after certain pressure is applied, the metal plates such as the door plates can be rapidly molded at one time and are fully automatically operated. However, the method has the defects that for large-size vehicle doors, large hydraulic equipment with a large workbench surface is required, the price is too high, the investment is large, the equipment is fixed, the flexibility is poor, the equipment and a production line cannot be integrated together, special lifting equipment is required for workpiece loading and unloading, lifting workers and operators are required to be equipped for correction, labor and time are wasted, the efficiency is low, the universality is low, the conventional hydraulic equipment takes hydraulic pressure limiting braking into consideration, and pipe distribution is convenient, so that the oil cylinder is mostly inverted, namely the oil cylinder is arranged above the workbench, and the defect that oil leakage pollutes products exists. Disclosure of Invention The invention aims to provide a side-opening correction device for an open wagon, which is used for solving the technical problems that the conventional side-opening correction mode for the open wagon is low in universality, inconvenient in production line layout, troublesome in feeding and discharging operations, unable to guarantee correction precision, complex in structure and high in cost. The basic scheme is that the correction device for the side opening door of the open wagon comprises a correction tool and a transmission device, the correction tool is connected with a production line through the transmission device, the correction tool comprises a frame body, two opposite bending parts are arranged on the left side and the right side of the upper portion of the frame body, a movable cushion block capable of moving left and right is movably connected below the bending parts, a plurality of correction cylinders are arranged on the lower portion of the frame body, the transmission device is fixedly connected in the middle of the frame body and used for horizontally transmitting the side opening door between the movable cushion block and the correction cylinders, the movable cushion block is used for limiting th
