The structure of the swivel footboard for the crew compartment of the fire truck

Abstract

The invention relates to a rotary pedal structure for a crew department of a fire engine, and belongs to the technical field of fire engines. The rotary pedal structure comprises a crew department, wherein the bottom of the crew department is provided with a crew department under carriage used for fixing a chassis of the fire engine, and one side of the crew department is pivoted with a crew department door. The rotary pedal structure of the crew department comprises a pedal body pivoted with the crew department under carriage and connected with the crew department door. When the crew department door is closed, the pedal body is unfolded into the bottom of the crew department; and when the crew department door is opened, the pedal body is unfolded out of the bottom of the crew department along with the crew department door. The rotary pedal structure has the advantages that the linkage of the crew department door and the pedal body is ensured, and the pedal body is in a hidden state to avoid damage when the fire engine runs; and the door opening action and the movement of the pedal body are combined into one, so that the valuable relief time of firefighters is saved.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting vehicles, and in particular relates to a rotary footboard structure for a passenger compartment of a fire-fighting vehicle. Background technique [0002] The fire truck crew compartment is usually located between the cab and the compartment used to carry the liquid storage tank (the liquid storage tank is filled with water or fire extinguishing foam), and the passenger compartment is equipped with a passenger compartment door for firefighters to enter and exit.

Problems solved by technology

But there are the following defects: one, due to the need to manually complete the process of showing the side part of the vehicle and hiding the tread plate at the bottom of the vehicle, it is not suitable to be configured at the position of the passenger compartment door, because when the firefighters board After the car enters the crew compartment, the running boards cannot be stored at the bottom of the vehicle, unless the running boards can be concealed after the disaster relief is completed and the vehicle returns to the destination and all firefighters get off the vehicle. , the running board is still displayed on the side of the vehicle; second, since the running board is displayed on the side of the vehicle and returned to the bottom of the vehicle by manual operation, it is inconvenient to use and is not conducive to saving every minute of firefighters.
