Abstract
The invention discloses a cross slider type sliding plug door mechanism, relates to an opening/closing and sealing mechanism of a sliding plug door for a high-speed train, and is particularly applied to opening/closing and sealing the door of a subway or the high-speed train. The cross slider type sliding plug door mechanism consists of a stepping motor, a screw rod, a screw rod nut, a support, a main shaft, a cross slider, a guide rod, a sliding plug door body, a guide wheel and a guide slot. The main shaft is fixed on the support. One hole in the cross slider matches the main shaft and can slide along the main shaft, and another hole of the cross slider perpendicular to the hole is matched with the guide rod. The sliding plug door body is fixedly coupled to the guide rod through a bolt. The guide wheel is arranged on the guide rod, and is limited in the guide slot to move. The guide slot is made into a shape of a line and a circular arc. When the guide wheel is driven by the cross slider to move along the guide slot, the guide wheel drives the sliding plug door to open and close and the sliding plug movement is realized. The movement of the cross slider is realized by driving the screw rod to rotate through the stepping motor, so the screw rod nut moves linearly, and the screw rod nut is fixedly coupled to the cross slider.
Description
Technical field
What cross slider type sliding plug door mechanism of the present invention related to is a kind of switch and sealing mechanism of high speed train plug sliding door, is specially adapted to the switch and the sealing of the door of subway or high speed train.
Background technology
Common train plug sliding door is two fan doors, realizes the motion to opening or closing, and in order to realize sealing at closing time, just must increase inside plug tension and compression and tightly move, and guaranteeing to close has good sealing effectiveness behind the door.In order to realize this function, can be divided into three kinds of different mechanisms substantially both at home and abroad, first kind is that homemade mechanism is representative; Mainly prolong the x direction realize door to Push And Release, realizes along the y direction that the plug roping is moving and reach sealing, but the main shaft that prolongs the motion of x direction is fixing; It moves with time delay y direction; Therefore main shaft stability is poor slightly, and scantling of structure is big, and occupation space is many.Second kind is to be the mechanism of representative with external certain company, prolong the x direction realize door to Push And Release, the main shaft that the x direction moves is fixed; Good rigidly; The plug roping is moving to be the rocking bar swing of having adopted around the rotation of x axle, drives the Sai La that double rocker mechanism is realized door, its good rigidly but size is big.The third mechanism also is that external certain company is the mechanism of representative, prolong equally the x direction realize door to Push And Release, main shaft is fixed, the plug roping of door is moving to be to have adopted around the four-bar mechanism of z revolution to realize that the plug of door draws sealing.
Summary of the invention
The present invention seeks to weak point to sliding plug door mechanism commonly used at present; A kind of cross slider type sliding plug door mechanism is provided, and is a kind of new plug sliding door kinematic mechanism, and the present invention has combined each tame strong point; Overcome the plug pull mechanism that each tame deficiency forms a kind of new cross slider type; Make the motion of plug sliding door more reliable, size is compact more, has also reduced cost simultaneously.
Cross slider type sliding plug door mechanism of the present invention is to take following technical scheme to realize:
Cross slider type sliding plug door mechanism is made up of stepping motor, leading screw, feed screw nut, bearing, main shaft, crosshead shoe, guide rod, plug sliding door body, track adjusting wheel, guide groove.
Main shaft is fixed on the bearing; One of them hole of crosshead shoe cooperates with main shaft and can prolong main shaft easily slides, and matches with guide rod in the orthogonal hole of another of crosshead shoe, and plug sliding door body and this guide rod connect firmly with screw; Track adjusting wheel is housed on guide rod; Track adjusting wheel is limited in motion in the guide groove, and guide groove is done to be in line and added the shape of circular arc, and just drive plug sliding door takes the air line and realizes the Push And Release of door when the straight line portion of track adjusting wheel guide groove in the drive lower edge of crosshead shoe moves; When track adjusting wheel is gone to the circular arc portion of guide groove, walked one section circular arc and realized that the plug roping is moving thereby then drive the plug sliding door.Wherein the motion of crosshead shoe is through the rotation of step motor drive leading screw, and feed screw nut is moved as straight line, and feed screw nut and crosshead shoe connect firmly, and crosshead shoe is also moved as straight line, moves along guide groove thereby drive the plug sliding door.
Principle of work:
During cross slider type sliding plug door mechanism work, the step motor drive leading screw rotates, and drives feed screw nut and moves as straight line; Feed screw nut and crosshead shoe connect firmly, and institute moves thereby the drive guide rod prolongs the x direction with the plug sliding door so that crosshead shoe moves axially along x; Realize the Push And Release of door; Because guide rod is passive movement with the plug sliding door body, receives the limit movement of guide groove, guide groove is designed to the geometric configuration that straight line adds circular arc; The straight line Push And Release of straight line control gate, and the plug that arc section forces door to walk one section circular arc realization door draws compound motion.
High speed train plug sliding door is switch and the sealing that is used for the door of subway or high speed train.Major requirement switch door is rapid, and plug draws sealing reliable, cross slider type sliding plug door mechanism of the present invention; The switch that can satisfy above-mentioned door is moving with the plug roping; But with above-mentioned how tame mechanism bigger difference is arranged, and structure is more simple and reliable, with low cost; Be plug sliding door cost-cutting, increasing fiduciary level provides assurance.
The present invention has combined each tame strong point, has overcome the plug pull mechanism that each tame deficiency forms a kind of new cross slider type, makes the motion of plug sliding door more reliable, and size is compact more, and also cost-cutting simultaneously increases the fiduciary level of plug sliding door motion.
Description of drawings
Below will combine accompanying drawing that the present invention is described further:
Fig. 1 is the cross slider type sliding plug door mechanism schematic diagram.
The specific embodiment
With reference to accompanying drawing 1, cross slider type sliding plug door mechanism is made up of stepping motor 1, leading screw 2, feed screw nut 3, bearing 10, main shaft 5, crosshead shoe 4, guide rod 7, plug sliding door body 6, track adjusting wheel 8, guide groove 9.
With reference to accompanying drawing 1; Said stepping motor 1 usefulness coupler 12 is connected with leading screw 2; Leading screw 2 two end axles are fixed on the compartment 10 through support, and feed screw nut 3 moves as straight line along with the rotation of leading screw 2, and said feed screw nut 3 connects firmly through connecting rod 11 usefulness screws with crosshead shoe 4.When feed screw nut moves; Force crosshead shoe 4 to move along axial (the x axis) that be fixed on the main shaft 5 on the compartment, move the Push And Release of realizing door thereby drive guide rod 7 with plug sliding door 6, it is driven member that guide rod 7 connects firmly with plug sliding door 6 usefulness screws; Track adjusting wheel 8 is housed on guide rod; Track adjusting wheel 8 can only be moved in the groove of guide groove 9, and guide groove 9 is fixed on the compartment, and is designed to the geometric configuration that straight line adds circular arc; The straight line Push And Release of straight line portion control gate, and the plug that arc section forces door to walk one section circular arc realization door draws compound motion.
