Abstract

The invention provides a powder tank truck manhole cover opening and closing control system. The powder tank truck manhole cover opening and closing control system comprises a powder tank truck uppercover, a manhole groove and a manhole cover plate; the manhole groove is formed in the powder tank truck upper cover; the manhole cover plate is connected to the top of the manhole groove in a slidingmode, wherein the manhole cover plate is connected to the inner side of the powder tank truck upper cover in a sliding mode; a similar horizontal pushing type driving mechanism used for driving the manhole cover plate is further formed in the powder tank truck upper cover; and a positioning mechanism used for positioning the manhole cover plate is further arranged in the powder tank truck upper cover. According to the powder tank truck manhole cover opening and closing control system, by arranging an air cylinder, a second touch switch, a first touch switch, a main control switch and a driving air cylinder, the air cylinder can be remotely controlled to extend and retract through the main control switch, and then the manhole cover plate is driven to move, so that opening and closing of the manhole groove are achieved; and therefore, automatic control is achieved, and time and labor are saved; and when the manhole groove is closed, the main control switch controls the air cylinder to drive the manhole cover plate to be closed, and the second touch switch touches a transmission block.

Description

technical field [0001] The invention relates to the field of powder filling vehicles, in particular to a control system for opening and closing a manhole cover of a powder filling vehicle. Background technique [0002] At present, the top cover of the dry-mixed mortar tanker is usually sealed with a manhole cover device. In order to avoid safety hazards caused by manual opening, an automatic manhole cover device is generally used. For example, the patent application titled "powder tank car" (CN200810210623) discloses a powder tank car, including a tank body, a manhole located on the top of the tank body, a sealing manhole cover device, a driving mechanism for sealing the manhole cover device, a piston cylinder The connection seat, the piston pulley movement method, and the valve. This patent application only adopts the sliding movement method, the manhole cover is poor in sealing performance, and the degree of automation is not high. Therefore, the present invention propose...
