Problems solved by technology

[0004] The above structure needs to be opened or closed manually. The powder tanker is bulky and needs to climb to the top of the tank to operate, which is inconvenient. Every year, operators fall from the top of the tank during high-altitude operation, causing casualties and posing potential safety hazards.

Abstract

The invention relates to an electric control powder tank car manhole cover which comprises a hole seat, a cover body and a connecting plate; the connecting plate is connected with the periphery of thehole seat; the cover body is in pivot joint with the hole seat; an overturning mechanism is arranged on one side of the pivot joint part of the cover body and is fixed to the connecting plate or thehole seat; the output end of the overturning mechanism drives the cover body to rotate by taking the pivot joint part as a shaft; and a group of locking mechanisms of the cover body is at least arranged between the cover body and the hole seat or between the cover body and the connecting plate. The electric control powder tank car manhole cover adopts a motor to drive the cover body to overturn and improves the locking mechanisms between the cover body and the seat body; the electric control powder tank car manhole cover and a matching motor realize remote locking and opening of the cover body; and the electric control powder tank car manhole cover does not need manual get-on to open the cover and close the cover for locking, so that the convenience and safety are greatly improved.

Description

technical field [0001] The invention relates to a manhole cover for a powder tank truck, in particular to an electrically controlled manhole cover for a powder tank truck. Background technique [0002] The powder tank truck is a special tank truck specialized in the storage and transportation of powder materials. It is suitable for bulk transportation of fly ash, cement, lime powder, ore powder, granular alkali, etc. It can save a lot of material packaging materials and manpower loading and unloading costs. Generally, there are multiple manhole covers in the vehicle part to realize powder feeding and maintenance. [0003] The existing manhole cover is as shown in CN103213781A, a pressure self-sealing device for a manhole cover of a powder tanker, including a tank body, a manhole seat connected to the tank body, and the upper part of the manhole seat is in contact with the manhole cover. Cooperate, there is a handle on the manhole cover, a sealing device is installed in the ...
