Automatic electric sanitation vehicle tail door opening and locking device

Abstract

The invention discloses an automatic electric sanitation vehicle tail door opening and locking device. The device comprises a tail door assembly, a lifting mechanism and a locking mechanism, the taildoor assembly is arranged in the middle of a rear end plate of a sanitation vehicle box body, and the lifting mechanism comprises a tail door opening and closing oil cylinder, a tail door opening andclosing oil cylinder support and an oil cylinder piston rod. The whole structure of the electric sanitation vehicle tail door opening and locking device greatly simplifies the opening and locking processes of a sanitation vehicle tail door mechanism, has the characteristics of one-key opening or locking, utilizes the action of one oil cylinder and achieves automatic opening after a tail door is unlocked through the matching action of all parts, and automatically locking is achieved after the tail door is closed; the tensioning action of the locking action can be achieved through two-stage inclined plane guiding when locking, meanwhile, a locking block has an adjustable function, and when a tail door sealing rubber strip fails for a long time, the tail door can be continuously tightened inwards to complete sealing of the tail door; and the device is simple in structure, operated conveniently and is worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of the tailgate of an electric sanitation vehicle, in particular, to an automatic opening and locking device for the tailgate of an electric sanitation vehicle.

Problems solved by technology

[0002] The sanitation vehicle is a special vehicle used for urban tidying and cleaning. The sanitation vehicle is mainly divided into the sprinkler series and the garbage truck series. The simple understanding of the electric sanitation vehicle is that it is driven by electricity. It is environmentally friendly, beautiful and reduces secondary pollution. And other advantages, it is used by the relevant sanitation system departments. As a cleaning tool, the electric sanitation vehicle has no pollution itself and has been recognized by the sanitation department. The electric sanitation vehicle has many advantages. To a certain extent, sanitation workers can reduce labor intensity, save labor costs, and improve work efficiency, but the existing electric sanitation vehicles still have the following disadvantages: the tailgate of the garbage collection compartment of the electric sanitation vehicle needs to be opened and closed during the garbage unloading operation, and the tailgate The door has a sealing requirement to ensure that the sewage cannot flow out after closing. The opening and locking of the traditional tailgate are complicated, and the sealing effect is not ideal, and it cannot be closed and automatically pre-positioned and tightened at the same time.
