Abstract

The utility model discloses a recovery vehicle for a tunnel. The recovery vehicle for the tunnel comprises a lifting arm assembly (10), a lifting mechanism (30), a rotary mechanism (40) and a chassis (50), wherein the rotary mechanism is arranged on the chassis, the lifting arm assembly is connected with the rotary mechanism, and the length of the lifting arm assembly is set, so that when the lifting arm varies and stretches, the chassis can be maintained stable. The recovery vehicle for the tunnel further comprises the lifting mechanism which can be installed on the chassis in a lifting manner. The chassis is an all-wheel steering and all-wheel driving chassis. As the chassis can be maintained stable when the lifting arm varies and stretches, the recovery vehicle for the tunnel can realize operations such as variation of amplitude and stretch without a supporting leg. After the recovery vehicle for the tunnel hoists and lifts the accident vehicle, the recovery vehicle for the tunnel can depart from the tunnel without turning around by means of joint effect of rotation of the rotary mechanisms and the all-wall steering and all-wheel driving chassis.
