Abstract

The utility model discloses a falling-prevention safety device of an overhead door. The falling-prevention safety device of the overhead door comprises an electromagnet, wheels, brake friction sheets, a steel wire rope and a rotating shaft. The brake friction sheets are fixed on the end portion of the electromagnet, the brake friction sheets and the electromagnet are fixed on the rotating shaft, the brake friction sheets are located between the electromagnet and the wheels, one end of the steel wire rope is fixed on the wheels, and the rotating shaft is sleeved with the wheels. When the overhead door is out of control and falls fast, the falling-prevention safety device can play of a role of protection, and the overhead door is prevented from falling fast so that people cannot be hurt and objects cannot be damaged.

Description

The anti-whereabouts of overhead door safety device
Technical field
The utility model relates to a kind of safety device, specifically, relates to the anti-whereabouts of a kind of overhead door safety device.
Background technology
At present, overhead door of the prior art has several modes, and a kind of is the lifting roll coil of strip, and the part that rises has exactly twisted in together; Another kind of overhead door is a whole plate, one end of wire rope is fixed on wheel, the other end is fixed on the lower end at gate, drive wheel by reducing motor, wirerope-winding is on wheel, it is exactly that gate will freely falling body when the wearing and tearing of the band-type brake of drive motors or wire rope rupture absolutely that this class overhead door has a shortcoming, can cause injury to the people under gate, and object is damaged.
The utility model content
The technical problem that the utility model solves is to provide the anti-whereabouts of a kind of overhead door safety device,, when overhead door is out of control while hurtling down, can play defencive function, prevents from the people is caused injury and object is damaged.
Technical scheme is as follows:
The anti-whereabouts of a kind of overhead door safety device, comprise electromagnet, wheel, lock friction plate, wire rope and rotating shaft; Described lock friction plate is fixed on the end of electromagnet, and described lock friction plate and electromagnet are fixed in described rotating shaft, and described lock friction plate is between described electromagnet and described wheel, and an end of described wire rope is fixed on wheel; Described wheel is sleeved in described rotating shaft.
Further: described wheel is by the reducing motor driven rotary.
Further: described wirerope-winding is on described wheel.
Further: the other end of described wire rope connects the overhead door top.
Technique effect comprises:
The utility model provides the anti-whereabouts of a kind of overhead door safety device, is characterized in playing defencive function when overhead door is out of control while hurtling down, and prevents from the people is caused and injures and object is damaged.
Description of drawings
Fig. 1 is the structural representation of the anti-whereabouts of overhead door safety device in the utility model.
The specific embodiment
In order to overcome the drawback of overhead door in prior art, the utility model provides a kind of safety device, when the wearing and tearing of the band-type brake of drive motors or wire cable rupture; can play the upper level protection; overhead door is controlled, prevented that hurtling down of overhead door from causing injury to the people, object is damaged.
Below in conjunction with accompanying drawing and preferred embodiment, the technical solution of the utility model is described in detail.
As shown in Figure 1, be the structural representation of the anti-whereabouts of overhead door safety device in the utility model.The structure of the anti-whereabouts of overhead door safety device comprises: electromagnet 1, wheel 2, lock friction plate 3, wire rope 4 and rotating shaft 5; Wherein, lock friction plate 3 is fixed on the end of electromagnet 1, and lock friction plate 3 and electromagnet 1 are fixed in rotating shaft 5, and lock friction plate 3 is between electromagnet 1 and wheel 2, and an end of wire rope 4 is fixed on wheel 2, and the other end is used for connecting overhead door; Wheel 2 is sleeved in rotating shaft 5, and wheel 2 is by the reducing motor driven rotary, and the rotation of wheel 2 can be wrapped in wire rope 4 on wheel 2.
Wheel 2 with automatic wire winding function can rotate and move axially in rotating shaft, wire rope 4 one ends are fixed on wheel 2, and the other end is connected with the overhead door top; When electromagnet 1 dead electricity, externally produce high-intensity magnetic field, electromagnet 1 will attract wheel 2, the frictional force between lock friction plate 3 and wheel 2 is greater than the torque of overhead door to wheel 2, when electromagnet 1 when electric, externally do not produce magnetic force, wheel 2 can freely rotate.Like this, the rotation of wheel 2 is just controlled by electromagnet 1, obtains electricly can rotate, and dead electricity can not be rotated, and effectively plays protective action.

Claims (4)
