Detailed description of the invention
Below in conjunction with the accompanying drawings the utility model is further described.
A kind of automatic moving door system as shown in Figure 1, including crossbeam 11 and be arranged on crossbeam 11 past for driving gate
The drive mechanism of multiple movement, drive mechanism branch sleeve assembly 6, sleeve assembly 6 connects door 48 by taking door frame;At horizontal stroke
Beam 11 two ends are respectively mounted hanger 49, and parallel equipped with two root length guide pillars 50 between hanger 49, sleeve assembly 6 is sleeved on
On long guide pillar 50, and can move back and forth on long guide pillar 50.
As shown in Figures 3 to 10, drive mechanism include the motor being fixed on crossbeam 11 the 1st, guide lock dog 51 and limit
Position mechanism 4, motor 1 is connected with controller;The axle connection wire rod 2 of motor 1, complete on screw mandrel 2 is configured with nut
Assembly 3;Nut assembly 3 include nut 31 and with nut 31 rigidly connected follow-up unit 7, nut 31 and screw mandrel
2 composition screws are secondary, be provided with gear frame 9, can relative transport between gear frame 9 with nut 31 outside nut 31
Dynamic;Be provided with torsion spring 10 between gear frame 9 and nut 31, torsion spring 10 with gear frame 9 for support to follow-up unit 7
Apply pressure, gear frame 9 branch sleeve assembly 6, during screw mandrel 2 rotates forward, drive nut 31 and follow-up unit
7 move simultaneously, when move to follow-up unit 7 with guide lock dog 51 contact after, follow-up unit 7 guiding lock dog 51 on
Leading of surface moves downwardly to position-limit mechanism 4 and is stopped by this position-limit mechanism 4, and follow-up unit 7 is rotated into screw mandrel 2
Guide the space between the side of lock dog 51 and position-limit mechanism 4 and be locked;When screw mandrel 2 rotates backward, follow-up unit 7
Rotate backward with screw mandrel 2 and unlock to the restriction departing from guiding lock dog 51, then along screw mandrel 2 axially-movable.Lead
Have one towards the side of position-limit mechanism 4 to lock dog 51, formed between this side and position-limit mechanism 4 can fall into servo-actuated
The space of parts 7.Side is for limiting the inclined-plane that follow-up unit 7 ejects, and the angle between side and vertical plane is
0-10 °, in this angular range, guiding lock dog 51 can apply active force to follow-up unit 7, again will not be because of angle mistake
Causing follow-up unit 7 by locked problem greatly, this angle is preferably 3 °.And also have in gear frame 9 and limit nut
31 with the mechanism of screw mandrel 2 rotational angle range, and this mechanism is a space, and the follow-up unit 7 on nut 31 is at this sky
Moving up and down with nut 31 between, the top and bottom in this space define the slewing area of follow-up unit 7, and then limit
Determine slewing area when nut 31 moves with screw mandrel 2.
As it is shown on figure 3, as the first embodiment, guide lock dog 51 and there is a guiding follow-up unit 7 to position restrainer
The smooth upper surface that structure 4 moves, in follow-up unit 7 motion process, when it does not connects with guiding lock dog 51 upper surface
It when touching, is in free state, be i.e. positioned at the lower end in the space that above-mentioned restriction follow-up unit 7 rotates, be arranged on nut 31
And the torsion spring 10 between gear frame 9 may be configured as being in the compressive state of relaxation state or less, does not executes to nut 31
