Detailed description of the invention
Referring to figs. 1 through Fig. 5, Fig. 1 to Fig. 5 is the structural representation of a specific embodiment of the present invention, as shown in the figure, connecting bridge treadle elevating appts, comprise lowering or hoisting gear main body 9, lowering or hoisting gear main body 9 comprises the cylindrical shell 1 that is arranged on Boarding bridge access envelope 10 one end, be arranged on the translation driving device 3 in cylindrical shell 1, the driving head assembly 2 being connected with translation driving device 3, the pedal 8 of connecting bridge is articulated in one end of passage envelope 10, driving head assembly 2 disposes a jack unit corresponding to connecting bridge pedal 8, the output of translation driving device 3 is a spur rack 31, cylindrical shell 1 one end is extended with an Extension support 11, jack unit is the eccentric wheel 4 being arranged on Extension support 11, eccentric wheel 4 lower ends are provided with the driving gear portion 41 corresponding with spur rack 31, eccentric wheel 4 is provided with the top splenium 42 corresponding with pedal 8.
As shown in the figure, translation driving device 3 comprises the motor driver 36 being arranged in cylindrical shell 1, drive motors 32, the decelerator 33 being connected with drive motors 32 output shafts, the screw rod 34 connecting with decelerator 33 output shafts and corresponding and be sleeved on the transmission nut 35 on screw rod 34 with screw rod 34, wherein decelerator 33 is a planetary reducer, on transmission nut 35, arrange and the corresponding guide ring 351 of cylindrical shell 1 inwall, transmission nut 35 is slidably matched by guide ring 351 and cylindrical shell 1 inwall, and transmission nut 35 is connected with spur rack 31, and the restriction of the connecting through hole on driving head assembly 2 transmission nut 35 rotates with spur rack 31 by transmission nut 35, need to promote pedal 8 time, motor driver 36 powers to drive motors 32, drive motors 32 rotates, and slow down and amplifying moment through planetary reducer, then drive screw rod 34 to rotate, thereby drive transmission nut 35 to move, under the restriction of transmission nut 35 and the connecting through hole of spur rack 31 on driving head assembly 2, transmission nut 35 can not rotatablely move, only can before and after translation, and drive spur rack 31 translations, make eccentric wheel 4 counter-clockwise swings, pedal 8 bottoms are pressed on splenium 42 tops in top, pedal 8 is risen, now Boarding bridge access does stretching motion, pedal 8 can scratch floor, effectively protect the ornament materials of gangway-floor.
As shown in the figure, in cylindrical shell 1, be provided with two buffer limit pieces 13 corresponding with transmission nut 35, the stroke of spur rack 31 is determined by the distance of two buffer limit pieces 13, therefore the pendulum angle of distance limit eccentric wheel 4 between two buffer limit pieces 13, while needing the pendulum angle of eccentric adjustment wheel 4, regulate distance between two buffer limit pieces 13, in the time that transmission nut 35 moves to buffer limit piece 13, with its collision, in the present embodiment, buffer limit piece 13 is made up of elastomeric material, now, buffer limit piece 13 not only plays position-limiting action, and can play cushioning effect, reduce the impact to mechanism, when collision, the electric current of drive motors 32 will increase thereupon, while reaching predetermined value, under the Current Control effect of motor driver 36, cut-off loop, make eccentric wheel 4 keep top to press pedal 8, keep the lifting state of pedal 8, facilitate stretching, extension or the contraction of Boarding bridge access, after the passage of connecting bridge stretches, when motor driver 36 is oppositely powered, drive motors 32 counter motions, eccentric wheel 4 swings clockwise, drives top splenium 42 to fall, now, eccentric wheel 4 no longer pushes up presses pedal 8, and pedal 8 is fallen under self gravitation effect, is overlapped on the joint of two passages, hide two passages due to the step that difference in height produces, facilitate passenger to walk.
Further, as shown in the figure, the top splenium 42 of eccentric wheel 4 is provided with a roller 43, and in the time of eccentric wheel 4 rotary oscillation, roller 43 contacts with the bottom of pedal 8, reduces friction, the lifting that makes pedal 8 smoothness more.
Further again, as shown in the figure, lowering or hoisting gear main body 9 is simple and compact for structure, and is arranged in less space, Boarding bridge access envelope 10 belows, one end by a mount pad 91, installs and uses very convenient.
Above better enforcement of the present invention is illustrated; certainly; the present invention can also adopt form different from the embodiment described above; the conversion being equal to that those of ordinary skill in the art do under the prerequisite without prejudice to spirit of the present invention or accordingly change, all should belong in protection scope of the present invention.
