Turnover-type footboard structure of fire truck

Abstract

The invention discloses a turnover-type footboard structure of a fire truck, belonging to the technical field of fire trucks. The fire truck comprises a device case body; and a door is arranged on the device case body. The turnover-type footboard structure comprises a pair of rotary arm support mechanisms arranged on an inner wall of a device case cavity and located at a cavity opening of the device case cavity, a pair of rotary arms, a footboard, a manual pulling frame connected with the footboard and a pair of acting cylinders arranged on the corresponding inner wall of the device case cavity and respectively connected with the pair of rotary arms, wherein one end of the rotary arm is respectively connected with the pair of rotary arm support mechanisms while the other end of the rotary arm is a free end, and two ends of the footboard are respectively fixed with the pair of rotary arms. The pair of rotary arms and the footboard are turned out of the device case cavity and hung at the cavity opening of the device case cavity by enabling the firefighter to hold the manual pulling frame when the turnover-type footboard structure is used, and the pair of rotary arms and the footboard are turned into the device case cavity by the manual pulling frame when the turnover-type footboard structure is to be collected, so that the service life is prolonged. The structure is simple, and the operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting vehicles, and in particular relates to an overturned footboard structure of a fire-fighting vehicle. Background technique [0002] In the prior art, the running board is usually fixed on the vehicle by welding or by means of fasteners. Although the running board of this structure can meet the requirements of firefighters, there are the following technical problems. One, once the running board is installed on the On the fire truck, it is always like a wing displayed on the side of the body. Specifically, even in the non-activated state, the running board is still deployed on the side of the body in a standby state, thus easily causing unnecessary obstruction 2. It is easily damaged. 3. It is not conducive to ensuring the cleanliness and viewing effect of the vehicle. [0003] In the published Chinese patent literature, there is no shortage of footboard structures for fire trucks. The utility...

Problems solved by technology

But there are following shortcomings: one, although the bottom or the bottom side of the vehicle can be concealed with the running board in the non-use state, the running board cannot be stored in the compartment cavity of the equipment compartment in the non-use state, so there is still damage. and the running boards, because when the vehicle passes by obstacles or similar obstacles on the road, it may be hit by obstacles; second, the service life is short, because the running boards are located at the bottom of the vehicle when they are not in use, but Still exposed to the outside world and thus vulnerable to environmental influences, such as being prone to rust and shortening the service life
