Special Vehicles with Wreckers

Abstract

The invention discloses a special vehicle with a barrier clearance device. The special vehicle comprises a vehicle body (1), a push shovel plate (2) and a driving part. The lower portion of the frontend of the vehicle body (1) is an inclined face which forwards inclines, and the upper portion and the lower portion of the push shovel plate (2) are hinged to the lower portion of the front end of the vehicle body (1) through an auxiliary support (3) and a main support (4) correspondingly; the vehicle body (1), the push shovel plate (2), the auxiliary support (3) and the main support (4) constitute a hinge four-rod mechanism, and the driving part is used for driving the hinge four-rod mechanism to move to enable the push shovel plate (2) to switch between the lowering position and the withdrawing position; and when the push shovel plate (2) is switched to the lowering position, the push shovel plate (2) is vertically arranged in front of the lower portion of the vehicle body (1) in a forwards and downwards movable mode, and when the push shovel plate (2) is switched to the withdrawing position, the push shovel plate (2) is attached to the lower inclined face at the front end of the vehicle body (1) in a backwards and upwards movable mode. The barrier clearance device of the special vehicle is small in occupied space and good in vehicle maneuverability and passing ability.

Description

technical field [0001] The invention relates to a special vehicle, in particular to a special vehicle with an obstacle removal device. Background technique [0002] Rescue and disaster relief are extremely urgent, but the roads passed by emergency vehicles and other special vehicles inevitably have complex road conditions and obstacles. If they cannot be cleared in time, it will hinder the smooth progress of rescue and disaster relief. Therefore, vehicles equipped with obstacle removal devices are required to open the road. [0003] The existing open front obstacle removal device for special vehicles is generally a parallel four-bar mechanism, such as the road obstacle removal device for a fire truck disclosed in Chinese Patent Application No. CN201310022980. , takes up a lot of space, and has a certain impact on vehicle maneuverability (main turning radius) and passability (approach angle), and is not suitable for vehicles with non-flat cabs, especially not suitable for som...
