Abstract
The utility model discloses an emergency entrance device for a railway vehicle door system, which mainly comprises a panel, a bracket, a baffle plate, a rotating shaft, a cable quadrant, a spring, a cylindrical pin, a cam, a square board and a positioning disc. In the utility model, the ratchet wheel principle is applied to the emergency entrance device; and the emergency entrance device is reliable to position. When the emergency entrance device is in an unlocked state, the baffle plate is clamped in a groove of the square board, and a bead positioned on the bracket is also clamped in the groove of the positioning disc at the same time, so that a steel wire rope is effectively prevented from driving the cable quadrant to invert and the entrance device is reliably positioned; and when the emergency entrance device is restored, the rotating shaft is reversely operated to prevent the baffle plate from restoring the friction force of the cam. In case of emergency, a rescue worker can provide a safe and reliable rescue channel by operating the device.
Description
Technical field
The utility model relates to a kind of emergency entrance device of guideway vehicle door system, belong to the technical field of door system.
Background technology
Emergency release is the operating important safety link of track traffic transportation device.In case of emergency, the rescue group can operate train-door system emergency entrance device, implements rescue action.This device mostly adopts and bumps the pearl locate mode at present, and its locate mode is also unreliable.In case of emergency, panic exit device is difficult to guarantee that door system is in the unlocked position, and has influenced emergency relief work to a certain extent.
Summary of the invention
The utility model proposes a kind of emergency entrance device of door system, overcome the above-mentioned defective that prior art exists.The ratchet principle is used to the emergency entrance device, had the reliable characteristics in location and have the location reliably.
Technical solution of the present utility model: it is characterized in that comprising panel, support, baffle plate, rotating shaft, cable quadrant, spring, straight pin, cam, side's plate and dowel disc, wherein panel is fixed on the car body, support is fixed on the car body by panel, rotating shaft is rack-mount, rotating shaft and key coupling, cable quadrant is installed in the rotating shaft, be connected with steel 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 blind recess, 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 dowel disc 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, mates with key.Cable quadrant is installed in the rotating shaft, is connected with steel 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 back shield 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, dowel disc 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.Dowel disc is installed in the rotating shaft and rotates synchronously with it.It is rack-mount and contact with dowel disc to bump pearl, and dowel disc is carried out auxiliary positioning, bumps the predetermincd tension of pearl and can adjust.
Advantage of the present utility model: the ratchet principle is used to the emergency entrance device, and this 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 dowel disc on the support simultaneously in the groove of square plate, prevents that effectively steel rope from driving cable quadrant counter-rotating, the reliable location of having realized inlet device; The reverse operating rotating shaft overcomes baffle plate the friction force of cam is resetted when resetting.In case of emergency, the rescue group can provide safe and reliable rescue passage by operating this device.
