Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
As shown in Figure 2,3, a kind of elevator door self adaption belt-tension regulating apparatus, comprises tension device, unidirectional self-lock device and traction gear; The tractive force of described traction gear is equal with the initial tension value of belt, this traction gear is connected with described tension device or described unidirectional self-lock device, described tension device is connected with described unidirectional self-lock device, and belt 30 is articulated between door motor 20 and described tension device.
Pass through such scheme, when belt 30 extends the tension force reduction causing tension force reduction or cause belt 30 due to other reason because plastic deformation elongation or other reason cause, under the tractive force of traction gear, tension device moves thus tightening belt 30, concrete as described in the utility model can only horizontal motion left, because the tractive force of traction gear is equal with the initial tension value of belt 30, tension force after belt 30 tensioning returns to original state, in belt 30 tensioning process, unidirectional self-lock device is not limited tension device, and after belt 30 recovers tension force, unidirectional self-lock device restriction tension device moves, tension device is avoided to reset.
As the part preferred version of above-described embodiment scheme, described tension device comprises follower 40 and tensioning support 70, tensioning support 70 and follower 40 are synchronized with the movement, can adopt preferably and be rigidly connected, described follower 40 is installed on described tensioning support 70 and mounts belt 30 by this follower 40, described tensioning support 70 is connected with described unidirectional self-lock device.
As the part preferred version of above-described embodiment scheme, described tensioning support 70 is provided with chock 50; Described unidirectional self-lock device comprises the limiting stopper 80 be fixedly arranged on car door rail frame 10, and described limiting stopper 80 is provided with rigidity toothed surfaces, and described chock 50 forms one-way intermittent motion mechanism with described limiting stopper 80.
As the improvement of above-described embodiment scheme, be connected in the spring 60 of compressive state by one between described tensioning support 70 with described chock 50, better ensure that tensioning support 70 is close to described chock 50 and is slided.
As the improvement of above-described embodiment scheme, also comprise cover plate 130, described cover plate 130 covers above described chock 50 and described limiting stopper 80, avoids described chock 50 to form one-way intermittent motion mechanism with described limiting stopper 80 and loses efficacy.
As the improvement of above-described embodiment scheme, the space width of described limiting stopper 80 rigidity toothed surfaces is different.
Limiting stopper 80 can be single also can be double, straight line time single, be arranged in parallel time double, as the preferred version of above-described embodiment scheme, described limiting stopper 80 is two and be arranged in parallel, described rigidity toothed surfaces is located on the opposing side of two limiting stoppers 80, and described chock 50 is between two described limiting stoppers 80.
As the part preferred version of above-described embodiment scheme, described traction gear comprises static pulley 110, tow rope 120 and pouring weight 90; Described static pulley 110 is installed on car door rail frame 10, described tow rope 120 is mounted on described static pulley 110 and one end is connected with described pouring weight 90, the quality of pouring weight 90 can adjust according to required tension force difference, the other end is connected with described tension device or described unidirectional self-lock device, and static pulley 110 can reduce hinder the frictional force of tow rope 120 motion and have leading role.
