Abstract
The invention discloses a linkage-type shutter structure for a fire-fighting truck, and belongs to the technical field of fire-fighting vehicles. The fire-fighting truck comprises a rescue carriage body, a carriage door and a shutter. The linkage-type shutter structure comprises a pair of traction rope connecting mechanisms longitudinally arranged on the middle-upper portions of two ends of the carriage door; first and second pulley shafts are arranged in parallel with each other and fixed between opposite cavity walls of a carriage cavity, first pulleys are arranged at two ends of the first pulley shaft, second pulleys are arranged at two ends of the second pulley shaft, and third pulleys are arranged at two ends of a third pulley shaft; the traction rope connecting mechanisms are arranged face to face and connected to the rear carriage wall in a position corresponding to the shutter, one end of each of traction ropes is connected with a pair of shutter linkage mechanisms, the other end of each of the traction ropes is connected with the traction rope mechanisms via the third, second and first pulleys, and the shutter is connected with the shutter linkage mechanisms. By the linkage-type shutter structure, working intensity of firefighters is alleviated, and ventilating speed of the carriage cavity is improved.
Description
