Abstract
The invention relates to an anti-drop device of an electric rolling shutter door arranged on transmission chain wheels. The device comprises a big chain wheel and an installing seat board, and is characterized in that a centrifugal device arranged on the big chain wheel can slide in longitudinal direction; the installing seat board is provided with a rotation stop block; and the rotation stop block is arranged on a position where the centrifugal device can reach during sliding.
Description
Technical field
The present invention relates generally to anti-drop device of electric rolling shutter door.
Background technology
The electric rolling door anti-drop device has crucial effects to the safe operation of support equipment.Existing falling proof device has two classes, and one is safety independently, complex structure, manufacturing cost height; Another kind of is anti-breaking chain apparatus, exist unreasonable structure, safety factor low, falling that the chain fracture time causes can only be solved, driving sections before the transmission hinge wheels such as sprocket fracture, the fracture of electric rolling door device mount pad and the electric rolling door device gear wear rolling door that the causes problem of falling that lost efficacy can't be overcome.
Summary of the invention
At the defective of above-mentioned prior art, the invention provides a kind ofly be convenient to assemble, cheaply, falling proof device that safety factor is high.
For achieving the above object, technical solution of the present invention is:
A kind of anti-drop device of electric rolling shutter door that is installed on the drive sprocket, it comprises hinge wheel and installation seat plate, it is characterized in that: but described hinge wheel is provided with the centrifugal device of longitudinal sliding motion, described installation seat plate is provided with the spline piece, accessible position when the fitting limit of spline piece is positioned at the centrifugal device slip.
Described centrifugal device be located on the hinge wheel, that a place is above, to the pod or vertical rail or the longitudinal tubule (L tubule) that extend away from the hinge wheel center of circle, in pod or vertical rail or longitudinal tubule (L tubule), be provided with slidably centrifugal lock, be provided with stopping means between described centrifugal lock and pod or vertical rail or longitudinal tubule (L tubule) or the hinge wheel, described stopping means satisfies: centrifugal lock can not collide with the spline piece or contact in original state, when the rotating speed of hinge wheel is worth greater than certain, centrifugal lock can overcome the restriction of stopping means and outwards slide under action of centrifugal force, and retaining is in the corresponding position of spline piece.
Described stopping means is that end connection centrifugal lock one end is fixed on the extension spring on the hinge wheel, the elasticity of extension spring satisfies when the rotating speed of hinge wheel is worth greater than certain, centrifugal lock can overcome the restriction of extension spring and outwards slide under action of centrifugal force, and retaining is in the corresponding position of spline piece.
Described stopping means is the draw-in groove that is fixed on the hinge wheel, and the draw-in groove end is provided with the wedge baffle plate, and the end that centrifugal lock is connected with draw-in groove is provided with screens, and the screens shape is complementary with the wedge baffle plate of size with draw-in groove.
Described stopping means is that end connection centrifugal lock one end is fixed on the stage clip on the hinge wheel, the pressure of stage clip satisfies when the rotating speed of hinge wheel is worth greater than certain, centrifugal lock can overcome the restriction of stage clip and outwards slide under action of centrifugal force, and retaining is in the corresponding position of spline piece.
Described stopping means is the opening elastic baffle that is fixed on the hinge wheel, and the end that centrifugal lock is connected with elastic baffle is provided with screens, and the opening of screens and elastic baffle is complementary in shape and size.
The usefulness of technique scheme is:
Rotating speed when the present invention has utilized rolling door the to fall increase centrifugal force that rotating speed is produced during greater than the electric rolling operate as normal, simultaneously also utilize hinge wheel and the characteristics of rolling door reel on same power transmission shaft of electric rolling door, thereby effectively overcome rolling door that the driving section inefficacy before transmission hinge wheels such as driving chain fracture, sprocket fracture, the fracture of electric rolling door device mount pad and electric rolling door device gear wear the causes problem of falling.
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.

Fig. 2 is present embodiment 1 sectional drawing
The specific embodiment
Embodiment 1:
A kind of electric rolling door falling proof device that is installed on the drive sprocket as shown in Figure 1, it mainly is made up of transmission hinge wheel 1, extension spring 2, centrifugal lock 3, spline piece 4 and installation seat plate 5.2 one of described extension springs are hooked centrifugal lock 3 one ends and are fixed on the hinge wheel 1, and centrifugal lock 3 is installed in the gathering sill 11 on the transmission hinge wheel, and centrifugal lock 3 can be in gathering sill under extension spring 2 pulling force or centrifugal action 11 moves; Described spline is fixed on the installation seat plate appropriate location soon, when centrifugal lock when suitable centrifugal action lower edge gathering sill is thrown away, the spline piece can block centrifugal lock, thereby stops hinge wheel to continue rotation, and then prevents that rolling door from continuing tenesmus.
Rotating speed when the present invention has utilized rolling door the to fall increase centrifugal force that rotating speed is produced during greater than the electric rolling door operate as normal, simultaneously also utilize hinge wheel and the characteristics of rolling door reel on same power transmission shaft of electric rolling door, thereby effectively overcome rolling door that the running part inefficacy before transmission hinge wheels such as driving chain 6 fractures, sprocket fracture, the fracture of electric rolling door device mount pad and electric rolling door device gear wear the causes problem of falling.
