Abstract
The utility model discloses a push rod air door, which is composed of a big door leaf, a small door leaf, a door frame, a track, a rolling wheel and an electric-hydraulic push rod. The door leaf is hinged with the small door leaf via hinges, the door leaf is wider than the small door leaf, the small door leaf is connected with the door frame via a rotating shaft, the upper end of the door frame is connected with one end of the track, the other end of the track is connected with the rolling wheel on the big door leaf, the middle part of the small door leaf is connected with the electric-hydraulic push rod, and the other end of the electric-hydraulic push rod is hinged to a laneway wall. Because the big door leaf is wider than the small door leaf, the dead angle can not occur when the air door is closed. The utility model has the advantages of simple structure, high safety, and easy application.
Description
The utility model relates to a kind of Electrohydraulic push rod air door, belongs to mine ventilation safety technics field.
The air door of installing in the present underworkings, a kind of is hand, often needs very big strength just can open air door (pressure reduction on air door both sides is big more, and the strength of opening the door is big more); Another kind is a lever, its complex structure, and processing and installation be difficulty relatively.Above-mentioned air door safety is relatively poor, and the workman once occurs and squeezed off trick, even by the serious accident of asphyxia by external pressure on the chest and abdomen.
The purpose of this utility model provides a kind of Electrohydraulic push rod air door of being made up of Electrohydraulic push rod, door leaf, roller, track etc., realizes automatic, the safety operation of air door.
The utility model is fanned the little door leaf that is connected through the hinge by the gate, big door leaf is wideer than little door leaf, the wicket fan pass is crossed gyroaxis and is connected doorframe, the doorframe upper end connects track one end, the track other end multiple in roller that big door leaf upside is connected on, wicket fan middle part connects Electrohydraulic push rod, and the Electrohydraulic push rod other end is articulated on the wall and constitutes.
The utility model has the advantages that simple in structure, easy to implement, laborsaving, safety, can realize electric blocking, control automatically between each air door.
Fig. 1 is an Electrohydraulic push rod air door front view.
Fig. 2 is an Electrohydraulic push rod air door vertical view.
(1) Electrohydraulic push rod, (2) little door leaf, (3) big door leaf, (4) doorframe, (5) roller, (6) track among the figure.
Describe below in conjunction with accompanying drawing.
Electrohydraulic push rod (1) produces when moving back and forth, and drives little door leaf (2), and little door leaf (2) drives big door leaf (3), and simultaneously, the roller (5) that links to each other with big door leaf (3) moves in track (4), thereby finishes opening or closing of air door.During unlatching, little door leaf (2) is opened 90 °, because big door leaf (3) is wideer than little door leaf (2), so between two door leafs certain angle is arranged during unlatching, occurs the dead angle in the time of can avoiding air door to close.Electrohydraulic push rod (1) is an electromechanical integrated product, is easy to realize automatic control.
Claims (1)
- A kind of Electrohydraulic push rod air door, form by big door leaf, little door leaf, doorframe, track, roller and Electrohydraulic push rod, it is characterized by the gate and fan the little door leaf that is connected through the hinge, big door leaf is wideer than little door leaf, the wicket fan pass is crossed gyroaxis and is connected doorframe, and the doorframe upper end connects track one end, the track other end multiple in roller that big door leaf upside is connected on, wicket fan middle part connects Electrohydraulic push rod, and the Electrohydraulic push rod other end is articulated on the wall.
