Preferably, the width of the abutment is equal to that of the main platform, the jacking block on one side of the mobile support is a rotatable jacking block, the pressing mechanism is a hydraulic telescopic cylinder, and the hydraulic telescopic cylinder has a greater pressing force than the air cylinder , more firm, the top block can be rotated to adapt to the bending part of different curvature.

Preferably, no less than three support plates perpendicular to the length direction of the main platform and the small platform are provided; each support plate is provided with a card slot, and the same side of the support plate is provided with a fixed workpiece The cylinder of the movable end of the cylinder is provided with a top block corresponding to the slot. The support plate plays the role of a stable support. The workpiece is placed on the support plate and then clamped by the cylinder to ensure accuracy during assembly and not easily deformed.

Preferably, rollers are provided on the main platform and the small platform, and hydraulic clamping devices are respectively provided at the front end of the main platform and the end of the small platform, so that the workpiece can be moved and further fixed on the platform conveniently.

The beneficial effects of the utility model: use the mobile support to weld the curved part of the girder, combine the assembly platform of the gooseneck girder and the straight girder into one, reduce the cost, and facilitate the operation; adopt the cylinder fixing method, the fixing is firm, It is safe and labor-saving, and improves the machining accuracy; it can move the required processing workpiece conveniently and labor-saving, and reduce the burden.

Detailed ways

Further illustrate the specific embodiment of the present utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, a semi-trailer beam assembly platform includes a main platform 1 and a movable small platform 2 arranged at its end. The main platform 1 and the small platform 2 are provided with no less than 3 vertical pieces. The support plate 8 in the length direction; each support plate 8 is provided with a card slot, and the wing plate is placed in the card slot for fixing during assembly, and then the web is vertically placed in the middle of the two wing plates, and the same side of the support plate 8 is provided with a fixed The cylinder 7 of the workpiece, the end of the movable end of the cylinder 7 is provided with a top block that is used to fix the workpiece relative to the draw-in groove. Between the main platform 1 and the small platform 2, a support platform 4 that can be adjusted in height is provided. A mobile support 5 for supporting the workpiece is provided above the support platform 4. A hydraulic telescopic cylinder 3 is provided on one side of the mobile support 5. The hydraulic telescopic cylinder 3. When assembling the girder, the upper and lower flanges of the girder can be fixed on both sides of the web according to the shape of the middle web for combined welding. The other side is equipped with a rotatable top block. The function of the top block is to adapt to different bending degrees. The neck of the girder better fixes the flange on both sides of the web. Both the main platform 1 and the small platform 2 are provided with supporting rollers 6 to facilitate the movement of workpieces, and the front and rear ends are also provided with hydraulic clamping devices 9 to further fix the processed workpieces after preliminary welding so as to perform final overall welding.

As shown in Figure 3, it is a schematic diagram of a gooseneck girder assembly platform for a semi-trailer girder assembly. The cut girder web 10 is placed in the slot of the support plate 8 on the main platform 1, and put into the straight upper and lower wing plates. After adjusting the position, operate the cylinder on one side of the support plate 8 to tighten the workpiece. At this time, the curved part of the web is just above the support platform 4. Use the mobile support 5 on the support platform 4 to move the straight upper and lower wing plates 10 according to the The cut web structure is profiled and initially fixed by spot welding. Since one end of the mobile support 5 is a rotatable top block, spot welding at multiple angles and places can be performed, which is beneficial to accurately determine the shape of the wing plate. At this time, the position of the small platform 2 is adjusted again, so that the preliminarily formed web and wing plate are fixed into the support plate of the small platform 2, and the hydraulic clamping device 9 at both ends is used to fix the whole, and then the final welding can be carried out.

As shown in Figure 4, it is a schematic diagram of a semi-trailer girder assembly platform to assemble a straight beam girder. The cut straight girder girder web is also placed in the slot of the support plate 8 on the main platform 1, and the same as the gooseneck type girder. The difference in the girder assembly process is that the mobile support 5 on the support platform 4 can be used to weld the bending part without adjusting the position of the small platform 2, and then the small platform 2 is fixed for the next welding.

The utility model combines the two most widely used girder assembly platforms, the gooseneck girder and the straight girder girder, to reduce production costs and save space; at the same time, the bending part of the girder is welded accurately, avoiding complex mechanisms and manual positioning The inaccuracy of the machine makes the processing quality greatly improved; it is more convenient to move the processed workpiece and reduce the workload of the operator.
