The hydraulic control system with a subframe leveling unit has the function of leveling a subframe, and the problem that rollover safety accidents are likely to be caused by dumper tilting in the left-right direction in the unloading process of a lifting type dumper is solved.

A concrete spraying mechanical arm only has the function of spraying concrete and does not have the function of concrete pumping. Crawler belt chassis are adopted for the mechanical arm and used for crawling. Leveling hydraulic air cylinders are arranged between a frame and the chassis, so that the mechanism arm performs construction on a ramp, wherein the gradient of the ramp is smaller than 30 degrees, and wet spraying performance is not affected. Hydraulic control is adopted for a multi-stage telescopic arm of a mechanical arm frame and can be freely operated in a narrow and long tunnel, a combination of manual speed adjustment and frequency conversion speed adjustment is adopted for the quantity of flows of additives, so that the control range of the quantity of flows of the additives is larger, and stepless adjustment is achieved. The mechanical arm can smoothly finish the concrete wet spraying operation in a narrow and small construction site and has the advantages of being small in size, light in weight, low in energy consumption and low in cost.

The invention provides a railway crane with outer rail superelevation levelling function and belongs to the crane field. The crane realizes levelling by arranging an arched beam levelling device between an upper vehicle frame and a lower steering frame. The device pushes the vehicle frame by a piston rod base matched with a double-boom oil cylinder such that the vehicle frame relatively slides along an arched beam matched therewith through skid shoes so as to gradually reduce the inclination degree of the vehicle frame above the arched beam to realize levelling; synchronously, as the double-boom oil cylinder can rotate with certain angle around the short shafts at the two sides of a cylinder with respect to the arched beam and the arched beam base plate can also slightly rotate with respect to the steering frame, the vehicle frame and the upper components can be levelled to be horizontal even though the arched beam and the steering frame connected to the lower portion of the arched beam are inclined. The invention solves the problem that the crane integrally inclines when the crane works at a railway curve by an integrated levelling device and ensures the rated hoisting performance and working safety when the crane works at a railway curve.
