The device is used on an up-sliding type electric door, after that, when the door body is static at the uppermost place, the shaft sleeve can do the synchronous rotation at the moment of starting a traction motor to drive the door body to do the downward motion; as the door body moves downward due to the self-gravity, the door body can not move along with the shaft sleeve instantly due to the static inertia, at the time, the steel wire rope roller can tighten the steel wire rope under the action of the elastic connecting mechanism, the utility model can maintain the synchronization with the movement of the door body within a certain scope, so as to achieve the purpose of preventing the loose of the steel wire rope.
Description
Technical field
The utility model relates to a kind of wire rope roll cartridge, especially a kind of wire rope roll cartridge that can be used for gliding style electric door lever gear door body.
Background technology
The driving mechanism of last gliding style garage door and industrial door mainly is made up of traction electric machine, power transmission shaft, wire rope and wire rope roll cartridge, the wire rope roll cartridge is fixed on the power transmission shaft by jackscrew, the two ends of wire rope are connected on reel and the door body, traction electric machine drives the folding and unfolding that the reel forward and backward realizes wire rope by driving power transmission shaft, and the door body rises automatically under the traction of wire rope or descends.At present, because the wire rope roll cartridge adopts the integral cast structure mostly, even if the wire rope roll cartridge that has is made of reel and axle sleeve, but it also is weldingly fixed on together, the roll device of this structure is after assembling with power transmission shaft and traction electric machine, during the motor rotation, reel promptly is synchronized with the movement with traction electric machine, like this, in door running body process, if traction electric machine shuts down because of certain reason, roll device is stall synchronously also, the door body causes wire rope lax because of inertia can continue preshoot at this moment; Particularly when the door body rise to horizontal level static after, in the moment that starter motor is closed the door, the motor band reel and is rotated synchronously, this moment, the door body also begins to rely on himself gravity to move downwards, because the startup acceleration of motor is greater than the startup acceleration of door body, within a certain period of time, the inevitable distance of length of steel wire rope that reel is put greater than the decline of door body, the result who causes thus is that wire rope is lax, and serious meeting causes wire rope disorderly to twine, and a body can not be moved, damage wire rope even, repair very difficult.
The utility model content
The purpose of this utility model provide a kind of under normal operating condition wire rope can remain the wire rope roll cartridge of tensioning state, prevent to be wound on the reel the wire rope pine disorderly.
For achieving the above object, the utility model adopts following technical scheme: locking random wire rope roll cartridge, comprise reel and axle sleeve, and reel has central through hole, reel is threaded onto on the axle sleeve circumferential surface rotationally by central through hole, is provided with flexible connection mechanism between reel and axle sleeve; Be installed with limit body on the bobbin trunk, correspondence is provided with and stirs body on the axle sleeve body, and axle sleeve realizes that by stirring body and limit body the rotating driving cooperates with reel.
Described flexible connection mechanism is one to be sleeved on the torsion spring on the axle sleeve circumferential surface, and torsion spring one end is fixed on the bobbin trunk, and the other end is fixed on the axle sleeve body.
Be provided with the torsion spring accommodation space at the axle sleeve body between the part of reel inside and reel, torsion spring set is loaded on the circumferential surface of the axle sleeve body that forms this space.
Torsion spring is fixedlyed connected with the axle sleeve body by a special fastener, and this special fastener comprises the main body with jack, and insert in this jack the torsion spring termination, and by fixing with the crossing tight fixed bolt of this jack; The main body top has alignment pin, the main body side mask has and axle sleeve junction plate tangent, that installing hole is arranged on it, be provided with locating hole and screwed hole with alignment pin and the corresponding position of junction plate installing hole on the axle sleeve, special fastener is fixedlyed connected with axle sleeve with the fastening bolt in passing junction plate screw-in screwed hole by the alignment pin that inserts in the locating hole.
Described locating hole and screwed hole are on the same cross section of axle sleeve.
Described limit body has two, and two limit bodies all are fixedly arranged on the reel end face, and forms certain included angle at circumferencial direction; The described body of stirring extends radially outwardly along axle sleeve, and length reaches in limit body; Reel realizes that by stirring the different limit body of body rotation replacing driving the rotating driving cooperates with axle sleeve.
Two limit bodies are fixedly arranged on the same circumference in the same end face of the reel outside, and the same body of stirring rotates the different limit body of replacing driving between two limit bodies.
Described limit body has one, and this limit body is fixedly arranged on the reel end face; Stirring body has two, stirs body for two and extends radially outwardly along axle sleeve, and length reaches in limit body, and forms certain included angle at circumferencial direction; Reel drives same limit body realization rotating driving cooperation with axle sleeve by the different bodies of stirring.
Also be provided with the axially movable axially stop block of restriction reel on the axle sleeve body.
Described axially stop block comprises the reel location shaft shoulder and the axial locking device of being located on the axle sleeve body, and the length between the reel location shaft shoulder and the axial locking device and the height of reel adapt.
Reel of the present utility model can produce relative rotation with axle sleeve in certain scope, after being applied in it on gliding style electric door, under the driving of traction electric machine, stirring body rotates with axle sleeve, when stirring body and meet limit body, drive limit body and rotate together, thereby drive the folding and unfolding that the reel rotation realizes wire rope, make a body automatic open and close.When the door body is in the top when static, if start traction electric machine a body is moved downward, axle sleeve can rotate synchronously, because the door body relies on himself gravity descending, static inertia can not move it immediately with axle sleeve, cable drum at this moment can be under the effect of flexible connection mechanism the tensioner wire rope, keep within the specific limits and a door body synchronized movement, prevent the random purpose of wire rope pine thereby reached.Torsion spring places reel inside can make structure compact more; Special fastener utilizes alignment pin and fastening bolt torsion spring can be securely fixed on the axle sleeve, and simultaneously, alignment pin and fastening bolt can also prevent that special fastener from rotating the phenomenon that gets loose under the effect of torsion spring moment of torsion.
