Description

A kind of devices for taking-up of rolling door

The utility model relates to a kind of devices for taking-up of rolling door.

The devices for taking-up of rolling door is installed in outside the curtain sheet reel at present, needs by sprocket wheel, and the chain drive structure realizes the rotation of reel, thereby installing space is big, and is loosely organized.The manual chain of handling the rolling door lifting during especially for power failure hangs from above outside, influences the neat and artistic of rolling door.

The purpose of this utility model is to provide a kind of compact conformation, rolling door devices for taking-up that installing space is little.

The purpose of this utility model realizes by the device of being made up of reel, manual control device, mechanical type stop, braking motor, reducing gear, electrical equipment control part, braking motor and reducing gear place in the reel inner chamber, the reducing gear clutch end drives the drive sleeve that places in the reel inner chamber, but drive sleeve is the mechanism of the winding reel axis rotation that connects with the reel internal chamber wall, and manual control device and mechanical type stop place the outer end of reel.

The power set that this structure will be batched the curtain sheet are installed in the reel, drive the drive sleeve rotation by the reducing gear output during motor rotation, and drive sleeve drives the reel rotation again, and reel makes the stop action in rotation.

For making the utility model structure further compact, braking motor can adopt other magnetic self-control motor, manual control device is by forming with the handle vertical with bull stick with the bull stick of braking motor rotating shaft coaxial line, bull stick and handle are provided with intermeshing bevel gear and bull stick and handle all can be along axis reciprocating motion separately, when handle is in downward extreme position, unclamp mutually between the bevel gear, bull stick does not link to each other with machine shaft, handle is in when making progress extreme position, intermesh between the bevel gear, the effect of pulling out of pushing away in the bevel gear engagement process is moved bull stick in braking motor, link to each other with machine shaft by shaft coupling, and bull stick can be embedded in the machine shaft vertically.Connect by connecting pin between machine shaft and the armature, the pin-and-hole diameter is greater than the connecting pin diameter.The said mechanism operating principle is: the armature of braking motor and brake disc are in the friction closure state during motor dead electricity, when handle upwards promotes, bevel gear engagement on handle and the bull stick, gear exists the effect of pulling out that pushes away in engagement process to bull stick, therefore promotes bull stick to the motion of machine shaft direction, pushes connecting pin in the bull stick embedding machine shaft and moves in pin-and-hole, make armature break away from brake disc, meanwhile rotate handle,, thereby drive the reel motion by bevel gear and shaft coupling rotary electric machine axle.

For guaranteeing the safety of manual control device in running; a normally closed electrical source circuit breaking switching is installed between the reciprocating stroke of handle; when pushing away on the handle, bevel gear touches protection switch makes the whole system outage, thereby prevents to send suddenly the electric possibility that damages to the person.In addition, in order further to make compact conformation, mechanical type stop power input gear stretches into into reel inner chamber, and the internal tooth with gears engaged is arranged on the corresponding drum wall, during the reel rotation by the moving mechanical type stop action of intermeshing cingulum.Braking motor adopts the side magnetic braking motor, and the armature of side magnetic braking motor and brake disc contact surface are the conical surface, have so both dwindled the size of braking motor, have guaranteed that again braking moment does not reduce.

The utility model compares with prior art, and it will batch main part and be installed in roller shutter tube inside, save installing space effectively, make things convenient for construction; The side magnetic braking motor volume of Cai Yonging is little in addition, and motor rotation and electromagnetic actuation are even to be to come from same coil, the probability that electromagnet breaks down when having reduced by two tunnel energisings, and use the taper braking to strengthen braking moment.The utility model is also reformed manual control device, has cancelled chain and the lifting of rolling door is handled in the rotation that replaces handle, so outward appearance is clean and tidy; Employed stop drive method also makes total compacter, and the protection travel switch that manual control device is set up makes that use is safer.

By the following examples and in conjunction with the accompanying drawings the utility model is described further.

Fig. 1 is the example structure schematic diagram.

Fig. 2 is the partial cutaway diagrammatic sketch of Fig. 1.

Fig. 3 is that manual control device structure and motor cooperate schematic diagram.

Among Fig. 1, Fig. 2, the 1st, curtain sheet reel, reel inner chamber stage casing is a side magnetic braking motor 3, the 2nd, adopt three grades not have supporting floating construction sun planetary gear reducing gear, the motor transmission shaft 10 that runs up drives the first order planetary gear 9 of reducing gear 2, after the third-level planetary gear reduction, speed is reduced to required low speed, output on the drive sleeve 7 through its output wheel 8, drive sleeve 7 places in the inner chamber and by bolt 6 and links to each other with reel 1.Drive sleeve 7 is the rotations of winding reel axis, therefore drives the reel rotation by drive sleeve 7 and batches or put down the curtain sheet.One end of reel 1 installs manual control device 5 and mechanical type stop 21 outward, 4 li of the inner chambers of component positionings such as electrical equipment changeover portion between manual control device 5 and motor 3.

Among Fig. 3, the 25th, the power input gear of mechanical type stop 21, internal tooth 16 engagements on gear 25 and the reel inwall are in case reel 1 rotation has also just driven stop 21 actions by gear 23,24 like this.Manual control device 5 is made of with vertical with it handle 22 bull stick 15 of horizontal direction.Bull stick 15 can move back and forth along side magnetic braking motor 3 axis directions, and handle 22 can move back and forth vertically.Bull stick 15 and handle 22 all are installed with can intermeshing bevel gear 17,19, when handle 22 is in downward extreme position, throw off mutually between the bevel gear, bull stick 15 is because the effect of back-moving spring 27 is in the extreme position away from motor 3, when handle 22 moves up when bevel gear is intermeshed, bull stick 10 is pushed away the effect of pulling out and is moved to motor 3 directions, and its displacement can make bull stick head 14 extend in the shaft coupling 13 to link to each other with machine shaft 10.Shaft coupling 20 is offered a duct 26 that can allow bull stick 15 heads stretch into just at machine shaft 10 afterbodys, and respectively settles orthogonal straight pin 13,14 on bull stick 15 and machine shaft 10 junction surfaces.When moving up and down, handle 15 can lead to steel ball detent mechanism 20 location, travel switch 18 is set in the handle displacement simultaneously, in a single day brush up against the contact of travel switch 18 when moving on the handle 22, whole system is in off state, system was in channel status again when handle 15 moved down again, sent electricity to damage to personnel in the time of can preventing manual control so suddenly.Have a connecting pin 11 to pass duct 26 in addition and link to each other, and the pin-and-hole diameter is greater than connecting pin 11, so bull stick throws off to come can armature and brake disc being under the closure state top by connecting pin 11 when motor drive direction moves with armature.Thereby rotating shaft 10 can freely be rotated.In the present embodiment, armature 12 and brake disc contact surface are taper.Only need rotate crank 22 when carrying out manual control this moment, by the bevel gear commutation bull stick 15 rotated, and drives machine shaft 4 rotations by shaft coupling again, so just can lifting play roller shutter.
