Compared with the traditional expanding and excavating trolley, personnel can stand on the expanding and excavating trolley to directly drill, explode and remove slag, so that the underground construction is avoided, and the risk of drilling, exploding and removing slag is greatly reduced. Because the drilling operator does not need to bear hand wind drill to go down to the working face of the construction, namely the working face does not need to stand.
The included angle between the horizontal plane of the working platform 1-5 and the face surface of the expanding and digging work is controlled between 60 degrees and 80 degrees. The horizontal angle between the face and the working platform 1-5 is adjusted to be more than 60 degrees during the general expanding and digging. That is, after the trolley of the scheme is adopted, the face does not need to be in a traditional horizontal shape during construction, but is inclined by 60-80 degrees, and 60 degrees are generally adopted. The casting surface of the ballast is effectively controlled when the expansion digging is carried out, and the dollies are not easy to hurt people and damage.
The main frame 1-1 is provided with a reinforcing structure, the reinforcing structure comprises a first cross rod 1-11 arranged on the front side of the main frame 1-1, a second cross rod 1-12 corresponding to the first cross rod 1-11 arranged on the rear side of the main frame 1-1, a vertical rod perpendicular to the underframe 1-2 arranged in the middle of the main frame 1-1, a third cross rod 1-13 corresponding to the first cross rod 1-11 arranged between the vertical rods, and a third vertical rod 1-14 arranged between the third cross rod 1-13 and the main frame 1-1 and the upper platform 1-4.
