The specific embodiment
Preferred embodiment of the present utility model below is described with reference to the accompanying drawings.
Embodiment 1
The automatic operated barrier mechanism of embodiment 1 of the present utility model is made up of motor 1, gear pair 2, friction axis coupling 3, changement 4, shift fork 6, main shaft 7 and roadway gate 8 as shown in Figure 1.Described automatic operated barrier mechanism also comprises travel switch 9, and the trip switch 9 can adopt the no maintenance type automatic lid actuator that has obtained Chinese patent (ZL9820799.4), to prolong the working life of whole roadway gate mechanism.Shift fork 6, main shaft 7 and roadway gate 8 are formed striking gear, and wherein an end of main shaft 7 and liftable roadway gate 8 link, and the other end of main shaft 7 and a shift fork 6 link, and this main shaft 7 can rotate with shift fork 6.Pinion 21 in the gear pair 2 is sleeved on the output shaft of motor 1, meshes and drive its rotation with gear wheel 22, and gear wheel 22 can be integral with the enclosure designs of friction axis coupling 3, with simplified structure.
Described changement 4 comprises ball nut 41 and ball-screw 42, and a side is provided with shift fork 6 and cooperates the roll sleeve 43 that connects on this ball nut 41, and opposite side is provided with push rod 44; Ball-screw 42 links with above-mentioned gear wheel 22.
When motor turned clockwise, the pinion 21 in the gear pair 2 began rotation, drove gear wheel 22 rotations with its engagement simultaneously.Gear wheel 22 sends power to changement 4 by friction axis coupling 3, thereby realizes that ball nut 41 drives ball-screw 42 and moves to the diagram below.By moving of ball nut 41, roll sleeve 43 is stirred shift fork 6 and is rotated counterclockwise.Main shaft 7 rotates 90 degree thereupon when ball nut 41 moves to lower terminal position, roadway gate 8 also is converted to the upright position by horizontal level thereupon, roll sleeve 43 on the ball nut 41 pins shift fork 6 with main shaft 7 automatically together, meanwhile, push rod 44 touches travel switch 9, and travel switch 9 sends information and cuts off the action power of motor and provide the information that roadway gate 8 is converted to the upright position.
In like manner as can be known, when motor was rotated counterclockwise, ball nut 41 was moving above diagram on the leading screw 42, and shift fork 6 turns clockwise, thereby made roadway gate 8 be converted to horizontal level by the upright position.
Above-mentioned motor 1 can be to have big torque, the torque motor of slow-speed of revolution characteristic.
Adopt the automatic operated barrier mechanism of this kind structure, rotatablely moving of motor 1 is transformed to the low-speed rectilinear movement of ball nut by means of ball screw assembly,, because the transmission efficiency of ball-screw is high, the loss of other transmission links is also little, so overall efficiency height, the driving power of motor only need 1/3rd of traditional multi-stage gear transmission scheme.Because the motion of shift fork becomes cosine relation with nut, big more according to angular velocity, the principle that speed is more little, striking gear is minimum at the rotating speed of two extreme positions of first and last, and the roll sleeve that is provided with on the ball nut during main shaft EOC pins shift fork again automatically, therefore, roadway gate during with the main shaft EOC speed minimum therefore need not to establish in addition buffer and lock structure almost without any impact.In addition, control module adopt to obtain the no maintenance type automatic lid actuator of national patent, has therefore improved the working life of whole roadway gate mechanism greatly.
Embodiment 2
Embodiment 2 is basic identical with principle and the structure of embodiment 1, difference is: the automatic operated barrier mechanism that embodiment 2 is provided is when the rotating torque of motor is enough big, can omit gear pair 2, thereby further simplify the internal structure of an organization, reduce the complexity of mechanism.The user mode of present embodiment and the beneficial effect that is produced are identical with embodiment 1, do not repeat them here.
Embodiment 3
Embodiment 3 is basic identical with principle and the structure of embodiment 1, difference is: the automatic operated barrier mechanism that embodiment 3 is provided has replaced ball-screw with gear ﹠ rack structure, gear 22 ' directly is sleeved on the output shaft of motor 1, tooth bar 23 1 sides are provided with shift fork 6 and cooperate the roll sleeve that connects, and opposite side is provided with push rod 44.When the output shaft driven gear 22 ' rotation of motor 1, drive the tooth bar 23 that is meshed with gear 22 ' and move up and down, this motion process and embodiment 1 mentioned above and 2 roughly the same, so do not give unnecessary details at this.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any ordinary skill is from the member; in not breaking away from design of the present utility model and protection domain; when doing a little conversion and modification, all should be as the criterion with claim scope of the present utility model.
