As preferably, be provided with breach separately on the bight of upper plate and lower plate correspondence, the shape at the shape of breach and the two ends of vertical beam matches, and the two ends of vertical beam and breach employing are welded to connect fixing.Breach can position the installation site of vertical beam, can also make simultaneously flange surperficial concordant of surface and upper plate and lower plate of vertical beam.
As preferably, described breach is stereo structure, and breach is formed by two L shaped mouthful of vertical butt joints, and L shaped mouth is arranged on top or two following vertical flange ends.Breach is stereo structure and represents that the limit of forming this breach is in the solid space, and two L shaped mouthful vertical mutually, and two such one L shaped mouthful limits are in a plane, and another two limits of L shaped mouthful also are in a plane, and these two planes are perpendicular.
As preferably, the junction of two side flangings of back and top and following two side flangings is provided with connector, and the degree of depth of this connector equates that with the width of flange connector butt joint back forms the right angle connection and stitches.Connector makes things convenient for the plate bending of the relative back with lower plate of upper plate, can not produce interference, also makes two side flangings of back plate dock the maintenance plane with the flange of upper plate and the flange of lower plate simultaneously.
As preferably, vertical beam is totally one on an angle steel structure, and the width of the angle steel of vertical beam is corresponding with the width of flange.The width dimensions of vertical beam is corresponding with the width of flange, makes the angle steel limit of vertical beam become the structure of the similar flange corresponding with flange, and planar structure of the corresponding formation of such two flange makes things convenient for to connect crossbeam as support between two flange simultaneously.
As preferably, the lower plate centre position is provided with square hole, and on the flange of machine frame periphery and the edge of square hole is provided with connecting hole.Square hole and connecting hole are to set according to the concrete equipment mounting means in machine frame inside
The beneficial effects of the utility model are: machine frame has only sheet material and vertical beam to be welded, and is relatively simple for structure, reduced number of molds, reduced the position of splicing welding, accelerated packaging efficiency.
