Description
Technical field
the invention belongs to fire-fighting vehicle technical field, be specifically related to a kind of convertible foot pedal structure of fire extinguishing tanker.
Background technology
prior art conventionally by tread plate with welding or be fixed on vehicle by means of fastener, although the tread plate of this structure can meet fire fighter's operating needs, but there is following technical matters, one, because tread plate is once being installed on fire extinguishing tanker, just puts on display the sidepiece in vehicle body just as one piece of wing consistently, specifically, even under non-initiate mode, tread plate is still deployed in Vehicular side body with readiness for action, thereby easily cause unnecessary obstruction; Its two, easily damaged; Its three, be unfavorable for the clean and tidy of support vehicles and sight effect.
in published Chinese patent literature, is no lack of the foot pedal structure that is seen in fire extinguishing tanker, utility model patent Granted publication CN200973933Y recommends to have " fire extinguishing tanker foot pedal structure ", this patent is to arrange for the equipment railway carriage or compartment of fire extinguishing tanker, standing on tread plate the chamber, railway carriage or compartment from equipment railway carriage or compartment for the ease of fire fighter extracts required fire fighting apparatus and materials and arranges, and under non-initiate mode, the exhibition of whole tread plate folding can be arrived to the outer bottom corresponding to equipment railway carriage or compartment of fire extinguishing tanker, thereby can eliminate aforesaid 3 technical matterss: patent of invention publication number CN101214801A provide " linkage wood clapper structure ", this patent is also aimed at the design of equipment railway carriage or compartment, there is the effect of different Qu Tonggong with aforementioned CN200973933Y, it is still for equipment railway carriage or compartment technique effect design and that can embody equally aforementioned CN200973933Y that invention patent mandate notification number CN101480936B announcement has " movable foot pedal device of fire extinguishing tanker ", this patent scheme, invention patent mandate notification number CN101480935B introduces has " the movable foot pedal structure of fire extinguishing tanker " and CN101973233B disclosure to have " linkage type foot pedal structure of used in fire-fighting ", these two patent schemes both can be applied to equipment railway carriage or compartment, also other position can be disposed at as the position of crew department's door, aforesaid 3 unfavorable factors can be eliminated equally.
the common feature that is not limited to the foot pedal structure of the disclosed fire extinguishing tanker of above-mentioned document is with manual mode, tread plate to be put on display to car body by fire fighter under initiate mode, and under non-working condition, makes it in hidden state.But there is following shortcoming: one, although can be by hidden tread plate bottom or the bottom side to vehicle at non-working condition, but can not be by tread plate in non-working condition be stowed to the chamber, railway carriage or compartment in equipment railway carriage or compartment, therefore still there is the anxiety that undermines tread plate, because when vehicle is at the obstacle on road or similarly when obstacle, clashed into by obstacle; Its two, service life is short, although because tread plate is positioned at vehicle bottom under non-working condition, be still exposed to the external world, thereby be subject to environmental concerns, for example easy-to-rust and reduction of service life.
