Description
Technical Field
The invention relates to a tank container, in particular to a longitudinal centering system and a longitudinal centering method for a tank body and a frame of the tank container.
Background
When the tank container is designed, in order to obtain larger loading volume, the difference between the length of the tank body and the length of the frame is extremely small, the tank body is regulated by relevant standards not to exceed the outermost edge of the corner fitting of the container, and the allowed offset of the longitudinal center line of the tank body (namely the axis of the tank body) and the longitudinal center line of the frame (namely the center line corresponding to the axis of the tank body) is extremely small, so that the difficulty of the process for assembling the tank body and the frame is greatly increased. As shown in fig. 1, after the end frame 02 of the can body and the frame is in a position, the end frame 02 and the positioning stopper 03 are pushed tightly by a pushing cylinder 04, and after the height position of the can body is adjusted, a longitudinal assembling (centering) process needs to be started. The existing tank body and frame assembly process mainly comprises the following two steps:
the first method is a direct center line alignment method, and the specific operation method comprises the following steps: measuring the total length of the tank body, drawing the position of the longitudinal center line of the tank body, determining the longitudinal center line of the frame, and longitudinally moving the tank body along the frame of the tank container by the tank body longitudinal displacement mechanism 05 to adjust the position so as to ensure that the longitudinal center line of the tank body is aligned with the longitudinal center line of the frame. The disadvantages of this method are: the total length of the tank body is difficult to measure, the efficiency is low, and the deviation of the longitudinal central line of the tank body determined manually is large, so that the pairing effect is poor.
The second method is a diagonal intersection method, and the specific operation method comprises the following steps: after the two end frames 02 of the frame are fixed, as shown in fig. 2, the intersection point of two diagonal lines of each end frame 02 is determined in a stay cord mode, the vertical distance from the intersection point of each diagonal line to the tank body end enclosure 01 is measured, and the position of the tank body is correspondingly adjusted until the distance from the two tank body end enclosures 01 of the tank body to the intersection point of the diagonal lines of the two end frames 02 meets the pairing requirement. The disadvantages of this method are: once the cotton rope becomes flexible, errors are easily caused, so repeated measurement is needed in the process of adjusting the position of the tank body, and the efficiency is low.
