[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0023] See also Figure 1-2 As shown, the utility model is a surfacing device for producing wear-resistant composite steel plates, which includes a roller conveyor, the roller conveyor includes a frame 10, support legs 11 and a driving roller 12, and a surfacing station is set at any position of the roller conveyor, and a surfacing mechanism and a lifting mechanism for lifting the composite steel plate 1 are respectively arranged above and below the frame 10 of the surfacing station; when in use, the composite steel plate 1 is placed on the roller conveyor for horizontal transportation, and when the composite steel plate 1 moves to the specified position of the surfacing station, the lifting mechanism is controlled to lift the composite steel plate 1 so that the bottom surface of the composite steel plate 1 is separated from the driving roller 12, and then the surfacing mechanism is controlled to perform the surfacing operation.

[0024] Specifically, Figure 1-2 The lifting mechanism includes a base plate 2 connected to the bottom of the frame 10 through a suspension rod 20, and a movable plate 22 is connected to the upper surface of the base plate 2 through a telescopic mechanism 21. A plurality of support frames 23 supported on the bottom side of the composite steel plate 1 are arranged on the upper surface of the movable plate 22, and the support frames 23 pass through the gap formed by two adjacent transmission rollers 12.

[0025] Similarly, in order to better fix the composite steel plate 1, the present application also arranges a clamping frame at both ends of the upper surface of the base plate 2, and the clamping frame includes a pair of telescopic structures A24, and a U-shaped frame 26 is detachably installed at the end of the pair of telescopic structures A24, and the U-shaped frame 26 passes through the gap formed by the two adjacent transmission rollers 12; a telescopic structure B27 is connected between the movable plate 22 and the base plate 2, and the telescopic structure B27 is connected to the telescopic structure A24; thereby, when in use, when the telescopic mechanism 21 is controlled to extend and drive the telescopic structure B27 to extend, the telescopic structure A24 contracts, that is, the gap formed by the U-shaped frame 26 and the support frame 23 gradually shrinks, until the U-shaped frame 26 and the support frame 23 respectively abut against the upper and lower sides of the composite steel plate 1 to fix and clamp the composite steel plate 1.

[0026] Specifically, the telescopic structure B27 includes an inner sleeve B and an outer sleeve B which are sealed and sleeved with each other; the telescopic structure A24 includes an inner sleeve A and an outer sleeve A which are sealed and sleeved with each other, the top of the inner sleeve A is connected with a connecting sleeve for inserting the U-shaped frame 26, and a locking bolt 25 is provided on the outside of the connecting sleeve, so that when in use, the depth of the U-shaped frame 26 inserted into the connecting sleeve is adjusted according to the thickness of the composite steel plate 1; when the composite steel plate 1 is thicker, the depth of the U-shaped frame 26 inserted into the connecting sleeve is controlled to be shallow, and conversely, when the composite steel plate 1 is thicker, the depth of the U-shaped frame 26 inserted into the connecting sleeve is controlled to be deeper.

[0027] The telescopic mechanism 21 mentioned above is a telescopic air cylinder or a telescopic oil cylinder.

[0028] A gantry welding frame is arranged on the frame 10 located above the surfacing welding station, and a machine head which can move on a horizontal plane along the conveying direction of the vertical roller conveyor is arranged on the gantry welding frame, and the machine head includes a laser welding head and a hot wire welding gun, the laser welding head is used to output a laser beam to focus on the surface of the workpiece to form a molten pool, and the hot wire welding gun is used to convey the welding wire to the molten pool; it also includes a laser generator connected to the laser welding head, and a hot wire heating device for heating the welding wire; the laser generator and the hot wire heating device are connected to a control system

[0029] On the basis of the above, when the composite steel plate 1 is longer, the welding range of the machine head is small, that is, it is necessary to control the composite steel plate 1 when it moves to the surfacing station during use. When the surfacing mechanism is used for surfacing, after each surfacing is completed, the composite steel plate 1 is controlled to move on the roller conveyor within the welding range of the machine head. Based on this requirement, a stepped limit mechanism is provided above the roller conveyor to limit the movement of the composite steel plate 1 on the roller conveyor.

[0030] like Figure 3The stepped limiting mechanism includes two inverted U-shaped brackets 13, a cross beam 13 is connected between the two U-shaped brackets 13, the bottom side of the cross beam 13 is connected to a movable beam 16 through three telescopic cylinders 15, and a plurality of baffles 17 are arranged at equal intervals along the length direction on the bottom side of the movable beam 16. Along the conveying direction of the roller conveyor, the distance between the baffle 17 and the upper surface of the composite steel plate 1 gradually decreases; and the distance between two adjacent baffles 17 is equal to the welding range of the machine head.
