Description

A folding electric gate

The utility model relates to a folding electric gate driven by a motor, which is suitable for gates with relatively large courtyard walls in enterprises, public institutions and government departments.

ZL92235067.1 discloses a folding electric door. The door is composed of a motor, an active door and a driven door. Drive rod is equipped with on the active door, and this rod one end links to each other with the screw mandrel in the motor rotating shaft, and motor is contained on the base, and fixed wheel is equipped with on the active door coaxially with rotating post, and this wheel is fixed on the base. The end of the rotating column connecting the driven door and the active door is equipped with a driven wheel. The main and driven wheels are on the same plane.

The door is driven by a motor to drive the drive rod to push the active door to rotate, and then the two doors are folded through the wire rope between the fixed wheel and the driven wheel on the two doors.

Compared with the side-opening or translational electric gate, the structure of this gate has the advantages of reducing the occupied space when opening and closing the gate, and there is no need to set up special guide rails for the gate; when the power is off, it can realize manual operation without taking large measures. Drive the gate. But, there are also some problems in this gate: the pulley-steel rope transmission often causes the transmission to fail because the tension of the steel rope decreases, loosens and slips during use. There must be two guide wheels between them; the drive of the main door is realized by pushing and pulling the telescopic screw rod matched with the cylindrical motor shaft of the inner screw nut. The shaft of the motor cylinder wears and loses a lot, which leads to the possibility of frequent maintenance and parts replacement.

The purpose of this utility model is designed for the problems existing in the above-mentioned folding electric door. Its driving mechanism and passive transmission chain structure can ensure continuous and reliable transmission, and the structure is simple and the operation is safe.

The structure of the present utility model is realized like this:

A folding electric gate is composed of a main gate, a secondary gate, a driving mechanism of the main gate, and a passive transmission chain centered on the rotational axis of the main gate and a radius from the center to the rotational center of the secondary gate. The drive mechanism of door (1) is to be made up of motor reduction gear (2), worm and gear (3), safety device (4), a pair of bevel gear (5), main door drive shaft (6), connect main door rotating shaft ( 6) and the connecting pin (7) of the main door (1) constitute; the passive transmission chain is to be fixed on the secondary door (9) rotating shaft ( 10) small sprocket wheel (11) and chain (12) on the form.

Below with an embodiment and accompanying drawing the structure of the present utility model is described in further detail.

Fig. 1 is the utility model, a schematic diagram of the front structure of a folding electric gate.

Fig. 2 is a schematic diagram of the working state of the utility model to open the door.

Fig. 3 is a schematic diagram of the working state of the utility model for closing the door.

A folding electric gate is composed of the main door, the secondary door, the driving mechanism of the main door, and the passive transmission chain with the rotation axis of the main door as the center and the radius from the center to the rotation center of the secondary door. The driving mechanism of door (1) is by the axle (6) [that is The main door rotating shaft (6)], connecting the main door rotating shaft (6) and the connecting pin (7) of the main door (1) are made up of; Chain wheel (8), and the little chain wheel (11) that is fixed on the rotating shaft (10) of secondary door (9) and the chain (12) on the chain wheel are made up of, and big chain wheel (8) is fixed on base Sitting still.

Another feature of the utility model is that a threaded adjustment device (13) and two symmetrically arranged spring devices (14) are installed on the chain (12). The effect of threaded adjustment device (13) is to adjust the tension degree of whole chain (12) by adjusting the screw on it to make it work normally. When the door was opened to limit position and blocked, two springs (14) act Function, one pull spring is stretched, and the other pull spring is compressed, which plays the role of buffering and speed regulation.

The working process of opening the door:

)实现开门。When the motor reduction device (2) starts to rotate in a certain direction, it drives the worm gear and the bevel gear (5), and the rotating shaft (6) of the passive bevel wheel (5) passes through the connecting pin (7) to make the main door (1) press Rotate counterclockwise (direction indicated by the arrow), because the chain (12) rotates counterclockwise with the main door (1) to make it also rotate around the large sprocket (8) counterclockwise, because the large sprocket (8) is stationary , the equivalent large sprocket (8) rotates clockwise along the center of itself, and at this moment, chain (12) just drives the small sprocket and the secondary door (9) to rotate clockwise along the center of the small sprocket (11). When the main door (1) turned to 90°, the secondary door rotated 180° along the center of the small sprocket (11) (the diameter ratio of the large and small sprockets

) to open the door.

The working process of door closing:

When the motor speed reduction device (2) starts to rotate in the other direction, it drives the rotating shaft (6) of the worm gear, the bevel gear (5), and the driven bevel gear (5) through the connecting pin (7) to make the main door (1) press smoothly. The hour hand (the arrow indicates the direction) turns, the same reason. Because the chain (12) rotates clockwise with the main door (1) to make it (chain) rotate around the large sprocket (8) in the clockwise direction, because the large sprocket (8) is stationary, it is equivalent to the large sprocket (8) rotate counterclockwise, and now, chain (12) just drives small sprocket (11) and secondary door (9) to rotate along the center of small sprocket (11) counterclockwise. When the main door (1) turned to 90 °, the secondary door (9) rotated 180 ° along the center of the small sprocket wheel (11) to realize door closing.

When the gate is in any position:

When running into a power outage and the gate is in any position, the coupling pin (7) is folded off. At this moment, the utility model folding electric gate is the same as the common gate, and can be arbitrarily pushed or pulled by staff to realize closing or opening the gate.

The structure of the utility model is novel, simple and reliable, and since the chain sprocket transmission is adopted, the continuous, stable and reliable transmission can be ensured. It occupies a small area, is simple and safe to operate, and can realize automatic or manual opening and closing of the gate. It is suitable for the gates of enterprises, institutions and government departments.
