Embodiment 1
[0027] In this embodiment, the chassis of the cantilever-type longitudinal-axis roadheader is used as the chassis, and a telescopic shield and a rotary shield are arranged on the front and upper part of the chassis to provide a wider and longer protection range for personnel working in front of the roadheader chassis, and a higher carrying capacity. The large temporary safety protection ensures that the construction workers get reliable and safe protection for the construction work in front of the roadheader chassis. Such as figure 1 , figure 2 and image 3 Commonly shown is a cantilever type excavation and protection integrated machine, the frame body 202 is connected with the double crawler type running part 201, and the two together form a chassis. The cantilever type longitudinal axis cutting part 100 is arranged on the upper front of the chassis.
[0028] The base 306 is installed above the chassis through a carrying mechanism, which is a significant difference compar...
Embodiment 2
[0035] Such as Figure 4 As shown, this embodiment is a simplified version of Embodiment 1, which removes the swing shield 308 and the swing power device that drives the swing shield 308 to swing.
Embodiment 3
[0037] Such as Figure 5 As shown, this embodiment is another simplified version of Embodiment 1, which removes the telescopic shield 307 and the telescopic power device that drives the telescopic shield 307 to expand and contract in the longitudinal direction, and directly connects the swing shield 308 to the base through the transverse hinge shaft. Seat 306 is hinged.
