Background
For soil milling equipment, such as a two-wheel slot milling machine, the mechanical equipment generally adopts a steel wire rope to suspend a working tool, a pair of rotatable cylindrical milling wheels is arranged below the working tool, and a plurality of cutter teeth are arranged on the outer ring of each milling wheel. Through the rotation of the cutter teeth, the milling wheel peels off soil, a blank area is formed below the operation tool, then the steel wire rope is placed downwards, and the milling wheel continues to dig holes.
In the soil milling and digging process, due to the fact that cutter teeth on the milling wheel are not uniformly distributed and the hardness of soil placed under the working tool is different, the flexibly connected working tool has the risk that the working tool does not vertically move downwards, and therefore the center of a slotted hole formed by milling and digging deviates in the vertical direction. In order to reduce the deviation phenomenon in the process of digging a slot hole, particularly in the process of digging an ultra-deep slot hole, a working tool is generally manufactured into a steel frame with a certain length, and a push plate device capable of adjusting the movement direction of the working tool is arranged on the frame.
Under the same depth of the slotted hole, the longer the steel frame of the working tool is, the better the guidance performance is, and the less the possibility of deflection is; meanwhile, the longer steel frame can also enable the push plate device arranged on the steel frame to be more far away from the milling wheel below the operation tool, so that the deviation rectifying effect of the push plate device is better. Therefore, the working tool (milling working device) of the existing double-wheel slot milling machine is generally about 10m, even longer, and reaches about 15 m. Therefore, the height of the whole double-wheel slot milling machine equipment is higher than 15m in order to meet the requirement of walking or displacement of a lifting operation tool.
However, with the continuous advance of urban construction in recent years, more and more double-wheel slot milling machines are used for construction under viaducts, and the long working tools often cause that the viaducts cannot be normally constructed.
