Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.
As shown in fig. 1 and 2, the safety access control device for a large oil tank of the present embodiment includes a fixing frame 1 installed on an escalator upright post 4 of an oil tank, a swing arm 3 is rotatably connected to the fixing frame 1, an actuating mechanism 2 for driving the swing arm 3 to rotate is installed on the fixing frame 1, and an output end of the actuating mechanism 2 is connected to the swing arm 3.
The swing arm 3 is rotated in the horizontal direction or the vertical direction under the action of the actuating mechanism 2 to realize the opening and closing of the entrance guard. To prevent unauthorized person loading the tank, the swing arm 3 is in a closed state. When the actuating mechanism 2 receives a remote electric signal or a remote gas signal, the swing arm 3 is driven to swing, the tank loading passage is opened, and people can pass through.
Specifically, actuating mechanism 2 includes cylinder 21, and the cylinder of cylinder 21 articulates on mount 1, and it has connecting rod 22 to articulate on the piston rod of cylinder 21, and the other end of connecting rod 22 is fixed with the pivot of swing arm 3.
