Abstract
The utility model discloses a safety clutch device of an electric roller shutter door, which is characterized in that at least three safety clutch device units are uniformly arranged on a brake rotary disc. In an embodiment, the safety clutch device of an electric roller shutter door is provided with four safety clutch device units symmetrically arranged on the brake rotary disc, each safety clutch device unit consists of two guide screw units, a clutch brake block, an extension spring and a pair of symmetrical friction plates, wherein the two guide screw units are fixed on the brake rotary disc, the clutch brake block is provided with guide grooves corresponding to the two guide screw units and is connected to the guide screws via the guide grooves, the clutch brake block is connected to the brake rotary disc via the expansion spring, and the friction plates are fixed at the top end of the clutch brake block. Compared with the prior art, the safety clutch device has the advantages of simpler structure, more flexible movement, higher safety and longer service life.
Description
Technical field
The utility model relates to a kind of safe arrangement of clutch that cooperates electric rolling door.
Background technology
Electric rolling door safety arrangement of clutch on the existing market (also claiming clutch to get rid of piece) mainly is to be used in the external hanging type electric rolling door and above the fireproofing electric rolling door.Because the door body weight of electric rolling door is big, under the situation of throwing off clutch, the motion that can produce freely falling body causes the damage of a body easily; On the fireproofing electric rolling door, in case of emergency, secure context is to stop after needing the door body to drop to the position of regulation, the delay regular hour continues to descend again, if the motion that the door body produces freely falling body, speed is uncontrollable, will also constitute a threat to the life property safety.Existing electric rolling door mainly is to increase safe arrangement of clutch, throws off the motion that clutch produces freely falling body to solve the door body, and performance tightens security.Safe arrangement of clutch as shown in Figure 3, its end by two clutch brake shoes 2 ' are articulated on the braking rotating disk 1 ', and an extension spring 4 ' connects the other end of two clutch brake shoes 2 ', and symmetrically arranged two wearing pieces 3 ' are individually fixed on the two clutch brake shoes 2 '.This safe arrangement of clutch complex structure, underaction, needs door body downstream rate is very fast just to play a protective role; Member is easy to wear, causes the damage of safe arrangement of clutch easily, and application life is short, poor stability.
The utility model content
At the defective that exists in the prior art, it is a kind of simple in structure that the utility model provides, and motion flexibly, and is safe, the electric rolling door safety arrangement of clutch of long service life.
For achieving the above object, technical solutions of the utility model are:
Electric rolling door safety arrangement of clutch, be characterised in that: it evenly is arranged at the braking rotating disk by the safe arrangement of clutch unit more than three groups and forms, described safe arrangement of clutch unit comprises that guider screw, a clutch brake shoe that is fixed on the braking rotating disk is slidingly connected to guider screw, extension spring connection clutch brake shoe on the braking rotating disk, and a friction plate is fixed in clutch brake shoe top.
The usefulness of technique scheme is:
The utility model compares by the electric rolling door safety arrangement of clutch with the existing structure complexity, has the following advantages: 1. friction plate is whole and rubs mutually with housing, rather than the single-point friction, thus not easy to wear, improve application life.2. each clutch brake shoe connects an extension spring, the centrifugal force that produces directly corresponds to extension spring, analyze from structure and mechanics principle, structure is advantages of simple more, the influence of spring force gas can not stretched, just could be in conjunction with friction when producing normally operation in conjunction with friction or rotating speed that need be very high, it is more flexible to move.3. by with four or more clutch brake shoe, than with below four, move more steadily, increased in conjunction with frictional force, the speed that easier control is descending avoids producing the movement of falling object, has improved security performance.

Fig. 2 is the utility model package assembly schematic diagram;
Fig. 3 is the prior art structural representation.
The specific embodiment
The utility model now is described in conjunction with the accompanying drawings and embodiments.
Electric rolling door safety arrangement of clutch 1 as shown in Figure 1, 2, it evenly is arranged at braking rotating disk 11 by the safe arrangement of clutch unit more than three groups and forms.The utility model is an example with four groups of safe arrangement of clutch unit that are symmetricly set on the braking rotating disk.As shown in Figure 1, this safe arrangement of clutch unit is provided with two gathering sills 121 by two guider screw unit 15, a clutch brake shoe 12 corresponding two the guider screw unit 15 that are fixed on the braking rotating disk 11, and described guider screw unit is connected in the corresponding gathering sill.Clutch brake shoe 12 is slidingly connected to guider screw unit 15 by corresponding gathering sill 121; One extension spring 14 connects clutch brake shoe 12 on braking rotating disk 11, and a symmetrically arranged friction plate 13 is fixed in clutch brake shoe 12 tops.
As shown in Figure 2, the utility model electric rolling door safety arrangement of clutch 1 is connected with an end of motor power shaft 2, when the normal up-downgoing of electric rolling door, the motor input shaft rotational speed is about 1300-1500 rev/min, clutch brake shoe 12 above the safe arrangement of clutch can produce centrifugal force, the friction because the effect of extension spring 14 pretensions, clutch brake shoe 12 can not combine with housing 3.When throwing off clutch handle 4, electric rolling door beginning under the deadweight of door body is descending, produced the motion of freely falling body, and drive motor power shaft 2 rotates, rotating speed has met or exceeded desired speed (being about 2000-2100 rev/min), the centrifugal force that clutch brake shoe 12 produces is greater than the pretension of extension spring 14, vertical outwards motion under the effect of guider screw unit 15, by the friction plate 13 beginning friction that combines with housing 3, control motor input shaft rotational speed is the 70%-80% of desired speed, thereby consistent when controlling the downstream rate of electric rolling door and normally moving, the motion of having avoided the door body to produce freely falling body.
Claims (3)
