Background

The patent with the name of a special all-terrain boarding tail board for the vehicle is disclosed in the existing Chinese patent database, the application number is CN202020680521.7, the application date is 20200428, the authorization notice number is CN212195224U, and the authorization notice date is 20201222, and the patent comprises a flat plate, a movable mechanism and a tread pedal; the flat plate comprises a flat plate body, a rotating lug and a rotating shaft, wherein a wheel-shaped ring is sleeved in the middle of the rotating shaft; the movable mechanism is a four-link horizontal transmission mechanism, and comprises a cutting rod, an upper connecting rod, a lower connecting rod and a front connecting rod, wherein the cutting rod is tangent to the wheel-shaped ring all the time, a tread pedal is hinged to be installed on the flat plate body and comprises a tread and front supporting lugs, the front supporting lugs are arranged on the front lower portion of the tread, and the front connecting rod is connected with the front supporting lugs of all treads, and the movable mechanism is not limited in that: this tailboard is opening the back, when placing subaerial, and the stress point does not have any strong point at the head end and the tail end of rear of a vehicle board in the middle part of rear of a vehicle board, leads to rear of a vehicle board middle part very fragile, has certain limitation.

Disclosure of Invention

The invention aims to solve the technical problem that after an existing fire-fighting vehicle door is opened, when a tail door is opened and placed on the ground, stress points are arranged at the head end and the tail end of a tail plate, and no supporting point exists in the middle of the tail plate, so that the middle of the tail plate is extremely fragile.

In order to achieve the purpose, the invention is realized by the following technical scheme:

the utility model provides a turn over a structure down convenient to heavy fire-fighting robot gets on or off bus, is including setting up the hinge at fire engine carriage afterbody, articulated on the hinge have turn over a door down, and the carriage bottom that is located the hinge inboard is provided with the connecting seat, it has the pneumatic cylinder to articulate on the connecting seat, and the piston rod free end of pneumatic cylinder is connected with turning over a door down, turn over a door lower surface down and from left to right the interval on be provided with long montant and short montant, be located and set up the connecting rod between long montant and the short montant, the connecting rod one end of slope is articulated bottom the short montant, and the other end is articulated at long montant middle part, long montant, short montant and connecting rod cooperation form parallel double crank structure, the long montant side of orientation pneumatic cylinder articulates there is the actuating lever, the other end and the pneumatic cylinder piston rod free end of actuating lever are connected.

When the downward-turning door at the tail of the carriage is in a vertical state after being retracted, the long vertical rod and the short vertical rod are arranged close to the lower surface of the downward-turning door.

Compared with the prior art, the invention has the beneficial effects that: because parallel double crank structure, pneumatic cylinder and the cooperation setting of turning down the door for long montant rotates along with the upset of turning down the door with short montant, when turning down the door and expand, provides the strong point for turning down the door middle part, prevents to turn down the door fracturing at the in-process of getting on or off the bus of fire-fighting robot, and whole device has the linkage, is applicable to in the industrial production, has very strong practicality.

The downward-turning door comprises a connecting support lug hinged with the hinge joint, a supporting plate is arranged at the other end of the connecting support lug, a reinforcing rib plate is arranged below the supporting plate, and the upper ends of the long vertical rods and the short vertical rods are hinged with the reinforcing rib plate.

And an anti-skid layer is attached to the upper surface of the support plate of the downward-turning door.

Rubber support legs are sleeved at the bottoms of the long vertical rods and the short vertical rods.
