Abstract
The invention discloses a double-open sliding plug door system. The system comprises a drive mechanism used for driving one side door to move in a reciprocating mode, a linkage mechanism matched with the drive mechanism and used for pulling the other side door to move in a reciprocating mode, and a sliding plug track. The system is further provided with a guide limiting rod and a limiting plate. One end of the guide limiting rod is fixedly connected with a fixing rack, and the other end of the guide limiting rod is a free end. The limiting plate is installed on a beam in a rotating mode. When the two side doors are closed under driving of the drive mechanism and the linkage mechanism, the limiting plate rotates until the free end of the guide limiting rod is stopped to restrain the pulled side door from moving back; when the two side doors are opened under driving of the drive mechanism and the linkage mechanism, the limiting plate rotates reversely to release the stopping effect on the free end of the guide limiting rod to enable the pulled door to move backwards. As the guide limiting rod is adopted, a bearing mechanism is restrained from moving on the fixing rack, the problem that under the circumstance of failure of the linkage mechanism, the driven door can be opened or closed freely is avoided, and the structure is simple and effective.

As shown in Figure 5, Figure 6, fixed mount 40 is also provided with guide and limit bar 42, its one end is fixedly connected with fixed mount 40, and the other end is free end; Limiting plate 13 is rotatably installed on crossbeam 11, and when closing under the drive of two side doors 48 at driving mechanism and link gear, limiting plate 13 rotates until stop the free end of guide and limit bar 42, limits a trailed side door travelling backwards; When opening under the drive of two side doors 48 at driving mechanism and link gear, limiting plate 13 reverses and removes the stop to guide and limit bar 42 free end, a trailed side door is back moved, after limiting plate 13 reverses and removes the stop to guide and limit bar 42 free end, guide and limit bar 42 approaches limiting plate 13 edge, and restriction limiting plate 13 rotates.
As Figure 13, shown in Figure 14, position-limit mechanism 4 also comprises a man-operated mechanism, this man-operated mechanism comprises one and is arranged on fixed support 20 on crossbeam 11 and a travel(l)ing rest 17 be arranged on bearing pin 14, between two supports, back-moving spring is installed, back-moving spring can be torsion spring, torsion spring set is at bearing pin 14, its one end is fixed on fixed support 20, the other end is fixedly connected with travel(l)ing rest 17, follow-up unit 7 can be transferred to by travel(l)ing rest 17 in rotary course from the space between guiding lock dog 51 and position-limit mechanism 4, be specially, the slide block 21 of a bending can be set in travel(l)ing rest 17 bottom, it transfers to by slide block 21 below follow-up unit 7 from the space between guiding lock dog 51 and position-limit mechanism 4, travel(l)ing rest 17 drives by manual stay cord 8 and rotates around bearing pin 14, manual stay cord 8 is connected with unlock switch, unlock switch can be a manual knob, manual stay cord 8 can be pulled during rotation.In actual applications, it is actually arranged on position that such as subway inwall etc. can make people easily touch.When turn unlock switch drives travel(l)ing rest 17 to rotate for center of rotation with bearing pin 14, slide block 21 promotes follow-up unit 7 and moves upward.Travel(l)ing rest 17 and limiting plate 13 are arranged on same bearing pin 14, and the two can not be interfered each other, and integrated level is high, can save installing space.
A kind of double open plug door system of the present invention, can be divided into following motion process and state:
1, electronicly to lock a door: controller sends signal to motor 1, motor 1 is made to drive screw mandrel 2 to rotate, screw mandrel 2 drives follow-up unit 7 axially to move to position-limit mechanism 4 along screw mandrel 2 by nut assembly 3, when follow-up unit 7 touches guiding lock dog 51, move downwardly to limiting plate 13 leading of guiding lock dog 51 upper surface and stopped by this limiting plate 13, follow-up unit 7 enters the space between the side of guiding lock dog 51 and limiting plate 13 with screw mandrel 2 rotation and is locked, in the process, limiting plate 13 rotates, trigger the signaling switch 15 arranged thereunder, after signaling switch 15 sends to controller the signal that puts in place, controller controls motor 1 stall, complete and lock a door.Now, it is anterior that limiting plate 13 is blocked in guide and limit bar 42 free end, and when link gear lost efficacy, the door due to active sleeve assembly 6 had been directed to lock dog locking, therefore can not be opened easily.And if there is no guide and limit bar 42, the door of driven socket assembly 61 side then can be manually opened, and drives whole crossbeam to carry out plug to pull work.Be provided with guide and limit bar 42, plug pulls work namely to be stopped, even if therefore manually pull the door of driven socket assembly 61 side, can not open.
2, electric open-door: controller sends signal to motor 1, motor 1 is made to drive screw mandrel 2 to rotate backward, follow-up unit 7 rotates backward to the restriction departing from guiding lock dog 51 with screw mandrel 2 and unlocks, and depart from limiting plate 13, limiting plate 13 is return under the effect of torsion spring, remove the stop to guide and limit bar 42, triggering signal switch 15 sends unlocking signal to controller, and then limiting component is along screw mandrel 2 axially-movable.When follow-up unit 7 moves to screw mandrel 2 other end, motor 1 stall, completes enabling, and now guide and limit bar 42 is in the top of limiting plate 13 and can limits limiting plate 13 reversed turning, avoids false touch signaling switch.
3, manually lock a door: manual actuation is sleeve assembly 6 initiatively, nut assembly 3 is axially moved to position-limit mechanism 4 at screw mandrel 2, and now screw mandrel 2 is passive rotation.When follow-up unit 7 touches guiding lock dog 51, move downwardly to limiting plate 13 leading of guiding lock dog 51 upper surface and stopped by this limiting plate 13, follow-up unit 7 enters the space between the side of guiding lock dog 51 and limiting plate 13 with screw mandrel 2 rotation and is locked, in the process, limiting plate 13 rotates, trigger the signaling switch 15 arranged thereunder, signaling switch 15 completes and locks a door after sending to controller the signal that puts in place.
4, open Door by Hand: during the locked door condition of both sides, by rotating unlock switch, make manual stay cord 8 pull travel(l)ing rest 17 to do clockwise direction around bearing pin 14 to rotate, the slide block 21 of travel(l)ing rest 17 is stirred from bottom by follow-up unit 7, follow-up unit 7 is made to leave latched position, torsion spring drives limiting plate 13 to rotate clockwise around bearing pin 14 simultaneously, and triggering signal switch 15, after unclamping unlock switch, travel(l)ing rest 17 rotates to original position under the driving of back-moving spring, then manual actuation controlled device 6, nut assembly 3 is axially moved to the direction away from position-limit mechanism 4 at screw mandrel 2, realization opens Door by Hand.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
