Description
Technical field
The utility model relates to automatic door field, and concrete is the embedding railing type automatic door that a kind of linear electric motors drive.
Background technology
Development along with Chinese Urbanization construction, the traffic system of the large flow such as the subway in city, between city, light rail, bus rapid transit is widely used, and how to ensure that the crowd of large flow is the problem that traffic system plan and management personnel show great attention to fast, in order, safely at platform by bus.
For guaranteeing passenger and vehicle insulation, some subway platforms adopt totally-enclosed or semi-enclosed door leaf type shield door, and some bus platforms adopt isolation rail or semi-enclosed door leaf type isolating door, have following several features in use:
1. totally-enclosed or semi-enclosed door leaf type shield door all adopts the transmission scheme of electric rotating machine+coarse pitch screw mandrel or Timing Belt, and procurement price is high, and working service cost is high;
2. the environmental requirement of using is high, can only be indoor or protect good occasion and use;
3. isolation rail scheme cost is low, but the passage of opening wide is difficult to the isolation of effective guarantee passenger and vehicle.
The utility model adopts and to be arranged on cylindrical linear on door pillar and to drive the railing type door leaf with secondary mandrel one, control device is controlled the Kai Heguan of door leaf as requested, while opening the door in the embedding hollow handrail of door leaf, it has simple in structure, purchase cost is low, installation, easy to maintenance, environment for use requires low, can be used for the adverse circumstances such as outdoor.
Utility model content
The utility model provides a kind of cost low, installation, easy to maintenance, the embedding railing type automatic door that environment for use requires low linear electric motors to drive.
The technical solution of the utility model:
The embedding railing type automatic door that linear electric motors drive, comprise driving door pillar, it is characterized in that: described driving door pillar is hollow cylinder, and its outer wall is provided with some through holes, its PATENT left side via oral area is connected with hollow handrail, in described through hole, through having upper and lower two embedded railing type door leafs and a secondary mandrel, the right-hand member of embedded railing type door leaf and secondary mandrel is connected by movable railing units; The place, aperture of described driving door pillar inside is all provided with arc surface positioning roller, and arc surface positioning roller is positioned at the upper and lower sides of embedded railing type door leaf, on secondary mandrel, is set with linear electric motors, on the upper wall of linear electric motors, door latch apparatus is installed; The right side of described movable railing units is installed with door pillar.
The embedding railing type automatic door that described linear electric motors drive, it is characterized in that: described door latch apparatus is comprised of displacement piece, fork, the described displacement piece of fixed installation on linear electric motors, on displacement piece, have cross section for " the displacement groove of { " type, the top of described displacement piece is by the hinged fork that is provided with of mandrel, the upper and lower side of fork is all connected with reference column, on the embedded railing type door leaf of linear electric motors top, has locating slot.
The embedding railing type automatic door that linear electric motors drive has the following advantages:
1. railing type door leaf is embedded in hollow handrail while opening the door, drives the space taking of door pillar little, without special protection is carried out in the location of door leaf and drive unit, simple in structure;
2. use linear motor direct drive door leaf, the driving of door leaf is without adopting electric rotating machine+coarse pitch screw mandrel or the transmission of Timing Belt and accurate auxiliary support structure, and purchase cost is low;
3. cylindrical linear has the anti-dust performance of good protection against the tide, the strong adaptability of environment, and reliability is high, long service life, convenient for installation and maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, the embedding railing type automatic door that linear electric motors drive, comprise and drive door pillar 1, driving door pillar 1 is hollow cylinder, and its outer wall is provided with some through holes, its PATENT left side via oral area is connected with hollow handrail 2, and in through hole, through having upper and lower two embedded railing type door leafs 3 and a secondary mandrel 4, the right-hand member of embedded railing type door leaf 3 and secondary mandrel 4 is connected by movable railing units 5; Drive the place, aperture of door pillar 1 inside that arc surface positioning roller 6 is all installed, arc surface positioning roller 6 is positioned at the upper and lower sides of embedded railing type door leaf 3, on secondary mandrel 4, is set with linear electric motors 7, and door latch apparatus 8 is installed on the upper wall of linear electric motors 7; The right side of movable railing units 5 is installed with door pillar 9.
Door leaf location and drive unit are arranged on the door pillar of fence passage one end railing, location and drive unit comprise linear electric motors, arc surface positioning roller, door locking and tripper, the secondary mandrel of linear electric motors passes through a structural member composition integral type railing type door leaf parallel with door pillar with upper and lower railing, the upper and lower railing of railing type door leaf and the diameter of secondary mandrel are less than the internal diameter of hollow handrail, while being arranged on the interior embedded railing type door leaf door opening state of upper and lower arc surface positioning roller and motor body, are embedded in hollow handrail.At closing time, control device is controlled motor and is produced the railing type door leaf that electromagnetic force promotes to be embedded in hollow handrail by secondary mandrel and move right, and when arriving right side door pillar, door latch apparatus automatic blocking prevents from by external force, being pushed open; While opening the door, door latch apparatus release, control device control motor generation electromagnetic force pulls railing type door leaf to move right by secondary mandrel and is embedded in hollow handrail, while arriving left side door pillar, stops; Railing type door leaf runs into object can not door-closing in-place time closing the door, and the resistance of motion of motor increases, and control device is judged the clamp position of door leaf by the current value that motor detected and increase, and folding can locking to door leaf again to control door leaf.
