The invention discloses a combined protection device and a wheeled crane. The combined protection device comprises a protection beam, a mounting support and a plurality of T-shaped bolts, two parallel T-shaped sliding grooves penetrating through the whole length of the rear side wall are formed in the rear side wall of the protection beam in the length direction, the T-shaped bolts can be assembled to any positions of the T-shaped sliding grooves, and a first mounting hole is formed in one end of the mounting support. The first mounting hole can be connected with the protective beam through a T-shaped bolt and a T-shaped sliding groove, a second mounting hole is formed in the other end of the mounting support, and the second mounting hole can be connected with a frame through a pin shaft. The installation support can be arranged at any position along the sliding groove, the installation requirements of different installation points can be met, and the problem that the specifications and types of protection beams are too many due to different installation points is solved. Meanwhile, according to the position of an installation point and the bearing condition, the reinforcing support can be installed at any position in the length direction of the protection beam, and therefore the strength and the deformation resisting capacity of the protection device are improved.

    本发明公开了一种组合式防护装置及轮式起重机。组合式防护装置包括防护梁、安装支座和若干T型螺栓,防护梁的后侧壁上沿长度方向设置有两条平行的贯穿后侧壁整个长度的T型滑槽,T型螺栓可以装配到T型滑槽上的任意位置,安装支座一端设置有第一安装孔,第一安装孔可通过T型螺栓和T型滑槽与防护梁连接,安装支座的另一端设置有第二安装孔,第二安装孔可通过销轴与车架连接。本发明可沿滑槽在任意位置布置安装支座,能适应不同安装点安装要求,解决安装点不同导致的防护梁规格种类过多问题。同时,根据安装点位置及承载情况,可沿防护梁长度方向在任意位置安装加强支架,从而提高防护装置的强度及抵抗变形的能力。
