Abstract
The invention discloses an emergency entrance device for a railway vehicle door system, which consists of a panel, a bracket, a baffle plate, a rotating shaft, a pull cord disc, a spring, a cylindrical pin, a cam, a square plate and a positioning disc. A ratchet principle is applied to the emergency entrance device, and the emergency entrance device has the advantage of reliable positioning. In an unlocking state, the baffle plate is clamped in a groove of the square plate, and simultaneously a colliding ball positioned on the bracket is clamped in a groove of the positioning disc to effectively prevent the pull cord disc from being driven to reversely rotate by a wire rope, and the entrance device is reliably positioned; and during resetting, the rotating shaft is reversely operated to overcome the friction force of the baffle plate to the cam. Under the emergency condition, rescue workers can operate the device to provide a safe and reliable rescue channel.

Summary of the invention
What the present invention proposed is a kind of emergency entrance device of door system, has overcome the above-mentioned defective that prior art exists.With ratchet principles to emergency entrance device, have the reliable characteristics in location and have the location reliably.
Technical solution of the present invention: it is characterized in that comprising panel, support, baffle plate, rotating shaft, cable quadrant, spring, straight pin, cam, square plate and positioning disk, wherein panel is fixed on the car body, and support is fixed on the car body through panel; Rotating shaft is rack-mount, rotating shaft and key coupling, and cable quadrant is installed in the rotating shaft; Be connected with wire rope in the cable quadrant water jacket, the crescent groove is arranged on the cable quadrant, cam is installed in the rotating shaft; Baffle plate is installed on the cable quadrant, and spring one end is pressed in the plate washer groove, and the spring other end is fixed on the cable quadrant; Straight pin is fixed on the support; Side's plate is fixed on the support, and square plate inboard is fluted, and positioning disk is installed in the rotating shaft and rotates synchronously with it.
Rotating shaft is rack-mount, and its both sides are the triangle cylindrical configurations, also can be the Any shape except that circular, matees with key.Cable quadrant is installed in the rotating shaft, is connected with wire rope in the cable quadrant water jacket.Cam is installed in the rotating shaft, and the cam outside is fluted and projection respectively.Baffle plate is installed on the cable quadrant, and the backboard that resets matches with the groove of cam, and the baffle plate inboard is fluted, and spring is pressed in the groove, and the spring other end is fixed on the cable quadrant.Straight pin is fixed on the support, and rotating shaft is positioned by straight pin after driving cam, cable quadrant, positioning disk half-twist.Side's plate is fixed on the support, and square plate inboard is fluted, and baffle plate is stuck in the groove under the effect of spring during released state, realizes reliably location.Positioning disk is installed in the rotating shaft and rotates synchronously with it.It is rack-mount and contact with positioning disk to bump pearl, and positioning disk is carried out assist location, bumps the pretightning force of pearl and can adjust.
Advantage of the present invention: with ratchet principles to emergency entrance device, this novel emergency entrance device has the reliable characteristics in location.During released state, baffle wedge is positioned bumping pearl and also can be stuck in the groove of positioning disk on the support simultaneously in the groove of square plate, prevents that effectively wire rope from driving cable quadrant counter-rotating, the reliable location of having realized inlet device; The reverse operating rotating shaft overcomes baffle plate the frictional force of cam is resetted when resetting.In case of emergency, the rescue personnel can provide safe and reliable rescue passage through operating this device.
