Referring to fig. 1 to 4, an embodiment of the present application provides a welding carriage. The welding carriage of this embodiment comprises a chassis 2, a first platform 1 and a second platform 3. The first platform 1 is rotatably connected to the chassis 2 about a first axis. The first axis is configured to extend in a transverse direction Y of the chassis 2. The second platform 3 is used for installing the working device. And the second platform 3 is configured to be rotatably connected to the first platform 1 about a second axis. The second axis is disposed parallel to the first axis.

According to the welding vehicle, the first platform 1 is arranged to be rotatable relative to the chassis 2, the second platform 3 is arranged to be rotatable relative to the first platform 1, and the rotation axes of the first platform 1 and the second platform 3 extend along the transverse direction Y of the chassis, so that when the welding vehicle walks on a slope, the first platform 1 can be controlled to rotate and the second platform 3 can be controlled to rotate, so that a working device arranged on the second platform 3 can be horizontally arranged, and the safety of the working device can be effectively guaranteed.

The working device may be a boom 4. Thus, the lifting arm 4 is in a horizontal state during lifting operation by leveling, and the safety of the whole machine lifting load is improved.

In other embodiments, the working device may also be a telescoping aerial ladder or a drilling rig.

The mountainous terrain is complex, and a transverse slope and a longitudinal slope may exist at the same time. A longitudinal slope means that the direction of inclination of the ramp extends in the longitudinal direction X of the chassis 2, that is to say that the height of the head and tail of the welding vehicle differs when the welding vehicle is driving on the longitudinal slope. The ramp shown in fig. 7 and 8 is a longitudinal ramp, and the head of the welding vehicle is higher than the tail of the welding vehicle when the vehicle ascends; when downhill, the head of the welding vehicle is lower than the tail of the welding vehicle. A lateral slope means that the oblique direction of the ramp extends in the lateral direction Y of the chassis 2, that is to say that the heights of the left and right sides of the welding carriage are different when the welding carriage is driven on the lateral slope. The ramp shown in fig. 9 is a transverse ramp, where the left side of the chassis is higher than the right side of the chassis.

As shown in fig. 7, when the welding vehicle runs on a longitudinal slope and goes up the slope, the first platform 1 is controlled to rotate anticlockwise, the second platform 3 is controlled to rotate anticlockwise relative to the first platform 1, and through the two-time angle transformation, the level of the suspension arm 4 is realized, the suspension arm 4 is ensured to be in a level state during lifting operation, and the safety of the whole crane lifting load is improved.

As shown in fig. 1, the first platform 1 is hinged above the chassis 2, specifically, the first platform 1 is hinged on a hinge shaft 11 extending along a first axis. This enables pitching of the first platform 1 relative to the chassis 2 when the first platform 1 is rotated about the hinge axis 11.

To improve the stability of the pitching movement of the first platform 1, in some embodiments the welding carriage further comprises two first drive cylinders 12 arranged on the front and rear sides of the first axis, respectively. Two first driving cylinders 12 are located one at the front side of the hinge shaft 11 and the other at the rear side of the hinge shaft 11. The first end of the first driving oil cylinder 12 is connected with the chassis 2, the second end of the first driving oil cylinder 12 is connected with the first platform 1, and the first driving oil cylinder 12 stretches and contracts to drive the first platform 1 to rotate around the first axis.

As shown in fig. 1, the two first drive cylinders 12 include a first front drive cylinder 121 on the front side and a first rear drive cylinder 122 on the rear side. Pitch control of the first platform 1 is achieved by the co-operation of the first front drive ram 121 and the first rear drive ram 122. And the first front driving cylinder 121 and the second rear driving cylinder 122 are both disposed obliquely. As shown in fig. 1, a first end of the first front drive cylinder 121 is connected to the chassis 2, a second end of the first front drive cylinder 121 is connected to the first platform 1, and in the longitudinal direction, the first end of the first front drive cylinder 121 is located on the rear side of the second end of the first front drive cylinder 121. A first end of the first rear drive cylinder 122 is connected to the chassis 2, a second end of the first rear drive cylinder 122 is connected to the first platform 1, and in the longitudinal direction, the second end of the first rear drive cylinder 122 is located at the rear side of the second rear drive cylinder 122. This arrangement makes the stroke range of the first front drive cylinder 121 and the second rear drive cylinder 122 larger, thereby expanding the rotation range of the first platform 1.

In some embodiments, the two first drive cylinders 12 include a first rear drive cylinder 122 on the rear side and a first front drive cylinder 121 on the front side. As shown in fig. 3 and 4, the welding carriage further comprises a first hinge seat provided on the first platform 1. The welding carriage further comprises a second hinge seat 14 provided on the first platform 1. The second end of the first rear driving cylinder 122 is hinged to the first hinge seat, and the second end of the first front driving cylinder 121 is hinged to the second hinge seat.
