A self-propelled hydraulic tapping device for a main beam automatic welding production line is shown in figures 1-2, wherein the main beam 3 automatic welding production line is provided with a roller bed frame 1, and roller shafts are arranged on the roller bed frame 1. The upper cover plate of the main beam 3 is placed downwards on the roller shaft, and the placing direction of the main beam 3 is parallel to the roller bed frame 1. Because the roll shaft can rotate freely, promote girder 3 and can make girder 3 remove along roller rack 1.

This self-propelled hydraulic pressure equipment of taking a percentage is including strideing on girder 3, and can follow the portal 4 of girder 3 length direction walking, and girder 3 can pass through in the portal 4. Specifically, the two sides of the roller way frame 1 are respectively provided with a track 2 parallel to the roller way frame 1, the lower end of the upright post 42 of the portal 4 is provided with a walking beam 43, the walking beam 43 is provided with a walking wheel 44, the walking wheel 44 is connected with a walking motor 45, and the portal 4 can walk along the track 2 under the driving of the walking motor 45. Since the gantry 4 can travel along the track 2, the tapping apparatus can be moved to tapping positions at both ends of the main beam 3. A pull-up mechanism and a push-down mechanism are provided on the beam 41 of the gantry 4.

As shown in fig. 2, the upward pulling mechanism includes a pair of upward pulling cylinders 5, a pair of upward pulling plates 6, and a pair of upward supporting shafts 7, wherein the upward supporting shafts 7 are used for supporting the upper cover plate of the main beam 3 upward. Bearings are installed at two ends of the upper supporting shaft 7, and the upper supporting shaft 7 can freely rotate around the axis of the upper supporting shaft. The lower ends of the pair of upper pulling plates 6 are respectively connected with the two ends of the pair of upper supporting shafts 7, and the upper ends of the pair of upper pulling plates 6 are respectively connected with the pair of upper pulling oil cylinders 5. When the pull-up oil cylinder 5 is contracted, the upper supporting shaft 7 is supported on the upper cover plate of the main beam 3, so that the main beam 3 can move upwards.

The pressing mechanism comprises a pair of pressing oil cylinders 8 and a pressing beam 9, the telescopic ends of the pair of pressing oil cylinders 8 are connected with the pressing beam 9, and the pressing beam 9 is used for pushing and pressing the lower cover plate of the main beam 3 downwards to enable the lower cover plate to be bent and attached to the web plate of the main beam 3. In order to enable the hold-down bar 9 to be pressed downward in parallel, guide rails 46 are provided on the pair of columns 42 of the gantry 4, respectively, and the sliders 10 are provided at both ends of the hold-down bar 9, respectively, and the sliders 10 can slide up and down along the guide rails 46.

Therefore, the upward pulling force generated by the pair of upward pulling oil cylinders 5 is balanced with the downward pressure generated by the pair of downward pressing oil cylinders 8, and the generation of bending moment is avoided. Similarly, in order to avoid the interference between the pressing-down movement of the pressing-down beam 9 and the pressing-up movement of the upper supporting shaft 7, as shown in fig. 4, the inside of the upper pulling plate 6 has a hollow structure, and the pressing-down beam 9 is located in the hollow structure of the upper pulling plate 6.

Starting the hydraulic pump, and enabling the pair of upward-pulling oil cylinders 5 to contract to enable the upper supporting shafts 7 to be supported on the upper cover plate of the main beam 3; at the same time, the pair of hold-down cylinders 8 starts to extend, so that the hold-down beams 9 are pressed on the lower cover plate of the main beam 3. Because the end of the web plate is provided with the inclined surface, the upper cover plate starts to bend under the action of pressure and is attached to the inclined surface of the web plate. Because the inclined plane can produce horizontal thrust, the horizontal thrust can make girder 3 produce and remove pushing down roof beam 9 in the in-process that pushes down, makes the bending and the laminating of upper cover plate go on in succession like this, accomplishes the processing of taking a percentage of bending. Since the upper support shaft 7 can rotate freely, the friction force between the upper support shaft 7 and the upper cover plate can be reduced.
