摘要:
The present invention provides a side wall of railway wagon and a boxcar of railway wagon. The side wall of the railway wagon comprises an upper side plate, a lower side plate, an inner side stake and an outer side stake, wherein the said inner side stake is arranged at the inner side of the said upper side plate and the said lower side plate, and the said outer side stake is arranged at the upper part of the said side wall of railway wagon and is arranged at the outer side of the said upper side plate. By applying the side wall in the form of internal stakes, the side wall of railway wagon and the boxcar of railway wagon of the present invention can make full use of the width space between the outer surface of the side plate and the outer surface of the side stake on the basis that the external dimension of the railway wagon is not changed, thereby effectively improving the volume of the railway wagon and the transporting capability of the train.

A lower locking pin body for the hinge joint between a lower locking pin and a lower locking pin hook has a suspending hole of a coupler lock lifter to facilitate it rotating surrounding the lower locking pin hook under the effect of the hole. There are two coupler suspending holes which are respectively arranged on each side ends of the lower locking pin body to facilitate the workers opening the coupler on either side of a car. A two-side operating coupler with above said lower lock pin body and a draft gear are provided, wherein the draft gear also includes two lock lifters and two lock lifter seats. The lock lifters are mounted into a key-shaped hole of the lock lifter seats, and the lock lifter has a limiting segment on the matched position. Two hook head ends of the lock lifters pass respectively out from the key-shaped holes of the coupler lock lifter seats and hang with the coupler lock lifter suspension hole of the two-side operating coupler. It has clearance between the limiting segment of the coupler lock lifter and a stripe-shaped hole wall of the key-shaped hole.

A container tank body and a processing method thereof are provided. The tank body is arranged in a frame with a square-shaped cross section and comprises a cylindrical main body part, end enclosures arranged at two ends of the cylindrical main body part and fixedly connected with the cylindrical main body part, and a tank body strengthening device. The cylindrical main body part comprises a plurality of parts with an arc-shaped cross section, the parts are formed by bending and welding a same panel, and the cross section of the cylindrical main body part of the tank body is generally arranged between the square-shaped cross section of the frame and an inscribed circle of the square-shaped cross section. A tank container comprising the tank body is also disclosed. As the cylindrical main body part is made by continuously bending a whole panel, the molding process is simplified so that the cylindrical main body part is only provided with one welding line, thereby remarkably lowering the leakage risk of the container tank body in use and improving the reliability of the container tank body in work; and the structure has quite strong self-anti-load capacity, thereby decreasing the number of the used tank strengthening devices and reducing the deadweight.

A lower lockpin rotation shaft assembly includes a lower lockpin rotation shaft body, an outer end portion thereof having a first coupler lifting bar hole, an intermediate portion thereof having a connecting key; and a lower lockpin rotation shaft bush, an outer end portion of the lower lockpin rotation shaft bush having a second coupler lifting bar hole, and an inner end portion of the lower lockpin rotation shaft bush being operatively connected to an inner end portion of the lower lockpin rotation shaft body. Further, the present invention further provides a double-side operating coupler and a coupler draft gear having the above lower lockpin rotation shaft assembly. The coupler draft gear further includes two coupler lifting bars and two coupler lifting bar seats. Each of the coupler lifting bars is inserted in a keyhole-shaped through hole of corresponding coupler lifting bar seat, and the coupler lifting bar has a restrained segment at a fitted portion of the coupler lifting bar with the coupler lifting bar seat. Coupler heads of the two coupler lifting bar are inserted through the keyhole-shaped through holes of the two coupler lifting bar seats and then coupled with the first coupler lifting bar hole and the second coupler lifting bar hole of the double-side operating coupler. There is a gap between the restrained segment of each coupler lifting bar and walls of the rectangular hole of the keyhole-shaped through hole.
