Description
Technical field
This utility model relates to rolling screen door technical field, particularly relates to a kind of rolling screen door chain broken prevention brake gear.
Background technology
Electric rolling door lifting is driven by door roller, and door roller typically drives spool turns by chain-drive mechanism, and reel drives the door curtain being wrapped on reel to slide up and down along door curtain guide rail and realizes switch gate.After use after a while, can there is the danger of fracture at any time in driving chain because of fatigue, and without taking safety prevention measure, door curtain can cause contingency because of deadweight tenesmus.Safety device of the prior art is usually when driving chain disconnects, and sticks in the gear teeth of sprocket wheel with lock pawl, stops sprocket wheel to rotate and prevents door curtain from dropping；But driving chain disconnects the most in the course of the work, namely break at sprocket wheel rotation process, now stick into lock pawl and the gear teeth allow sprocket wheel stop operating immediately, sprocket wheel and preventer can be produced bigger impact, sprocket wheel and preventer can be damaged, even do not have protective action.
Utility model content
This utility model overcomes the deficiencies in the prior art, it is provided that a kind of will not damage sprocket wheel and preventer, rolling screen door chain broken prevention brake gear that protection effect is good.
This utility model is achieved through the following technical solutions:
Drive sprocket and spool that a kind of rolling screen door chain broken prevention brake gear, the spool including supporting plate, fixing connection for the reel and drum center being wound around door curtain and door roller connect fix the driven sprocket of connection, driving chain；Described supporting plate is located at door opening both sides；Described spool and supporting plate are rotationally connected；Supporting plate side is located at by described drive sprocket and driven sprocket；Described driving chain connects drive sprocket and driven sprocket；Also include that chain broken prevention triggers device, electromagnetic brake and controller；Described chain broken prevention triggers device and is provided with bearing, guide rod, regulating wheel, spring and travel switch；Described bearing is located on supporting plate, is provided with pilot hole in the middle of it, and its lower end is provided with spring guide；Described guide rod runs through pilot hole and spring guide freely slidable；Described regulating wheel is located at lower end of the guide rod, can roll on driving chain；Described guide rod upper end is provided with pressing plate；Described spring housing is located in spring guide outside guide rod, its upper end pushing and withstanding bearing, and lower end pushes guide rod, makes regulating wheel be close to driving chain；The lower section of pressing plate is located at by described travel switch；The opposite side of supporting plate is located at by described electromagnetic brake, and its housing and supporting plate connect, and its rotating shaft and spool connect；Described travel switch, electromagnetic brake all electrically connect with controller.When normally working, electromagnetic brake solenoid obtains electric declutching, and spool can normal rotation；Chain rupture once occurs, and spring promotes guide rod to move downward, and guide rod band dynamic pressure plate touches travel switch, travel switch sends the signal of telecommunication to controller, and controller disconnects electromagnetic brake electromagnetic coil circuit, and electromagnetic brake dead electricity holds rotating shaft tightly, reel the most just stops operating, thus prevents door curtain from dropping.
As preferably, described spring is spiral compression spring.
As preferably, described chain broken prevention triggers device and is located between drive sprocket and driven sprocket.
As preferably, described electromagnetic brake is dry type electromagnetic brake.Dry type electromagnetic brake low price, safeguards simple.
As preferably, also include an emergency power supply, described emergency power supply and controller electrical connection.Emergency power supply unclamps electromagnetic brake when being used for having a power failure so that can be with hand switch rolling screen door.
The beneficial effects of the utility model are: use chain broken prevention to trigger device as chain rupture touch switch, reliable operation；Use electromagnetic brake as braking member, can effective brake, reel will not be made to stop operating immediately when braking and damage sprocket wheel and preventer again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A sectional view of the present utility model.
Fig. 3 is the structural representation that chain broken prevention of the present utility model triggers device.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
As shown in FIG. 1 to 3, embodiment of the present utility model, driven sprocket 5, the driving chain 6 connected fixed by drive sprocket 4 and spool 3 that the spool 3 including supporting plate 1, fixing connection for the reel 2 and reel 2 center being wound around door curtain and door roller connect；Described supporting plate 1 is located at door opening both sides；Described spool 3 and supporting plate 1 are rotationally connected；Supporting plate 1 side is located at by described drive sprocket 4 and driven sprocket 5；Described driving chain 6 connects drive sprocket 4 and driven sprocket 5；Also include that chain broken prevention triggers device, electromagnetic brake 7 and controller (being not drawn in figure)；Described chain broken prevention triggers device and is provided with bearing 8, guide rod 9, regulating wheel 10, spring 11 and travel switch 12；Described bearing 8 is located on supporting plate 1, is provided with pilot hole 13 in the middle of it, and its lower end is provided with spring guide 14；Described guide rod 9 runs through pilot hole 13 and spring guide 14 freely slidable；Described regulating wheel 10 is located at guide rod 9 lower end, can roll on driving chain 6；Described guide rod 9 upper end is provided with pressing plate 15；Described spring 11 is enclosed within outside guide rod 9 to be located in spring guide 14, its upper end pushing and withstanding bearing 8, and lower end pushes guide rod 9, makes regulating wheel 10 be close to driving chain 6；The lower section of pressing plate 15 is located at by described travel switch 12；The opposite side of supporting plate 1 is located at by described electromagnetic brake 7, and its housing and supporting plate 1 connect, and its rotating shaft and spool 3 connect；Described travel switch 12, electromagnetic brake 7 all electrically connect with controller.When normally working, the solenoid of electromagnetic brake 7 obtains electric declutching, and spool 3 can normal rotation；Once there is chain rupture, spring 11 promotes guide rod 9 to move downward, guide rod 9 band dynamic pressure plate 15 touches travel switch 12, travel switch 12 sends the signal of telecommunication to controller, controller disconnects electromagnetic brake 7 electromagnetic coil circuit, electromagnetic brake 7 dead electricity holds rotating shaft tightly, and reel 2 the most just stops operating, thus prevents door curtain from dropping.
