Abstract
An auxiliary mechanical brake used on an escalator and an automatic pedestrian path comprises a ratchet wheel, a pawl, a connecting rod, a travel switch and a sliding block component which are fixed onto a driving chain wheel. One end of the connecting rod matches with the travel switch; the other end of the connecting rod is fixedly connected with the pawl; the pawl is pivoted on a truss by the aid of a support; the sliding block component is pivoted with a component support; the component support is fixed onto the truss; the sliding block component matches with a driving chain; the travel switch is fixed onto the component support; one end of a hanging hook is connected with the sliding block component; and the other end of the hanging hook is connected with the connecting rod. When the driving chain breaks, (1) the siding block component loses the supporting force of the driving chain, the hanging hook drives the connecting rod to move downwards, the pawl moves upwards around a shaft, the pawl meshes with the ratchet wheel, and accordingly a spindle and the driving chain wheel stop rotating, thereby the escalator stops moving. (2) The connecting rod triggers the travel switch to transmit electric signals, and accordingly movement of the escalator and other parts is stopped, thereby the auxiliary mechanical brake achieves the purposes of ensuring safe running of equipment and preventing personal injury caused by stair reversal.
Description
Technical field
The utility model relates to a kind of escalator, especially a kind of brake equipment of escalator.
Background technology
Present prior art, a kind of escalator, when chain drive-belt ruptures, because the effect of step gravity, the step reversing will endanger passenger safety.
Summary of the invention
The purpose of this utility model is: the complementary mechanical brake of using on a kind of escalator and the automatic pedestrian path is provided, and when it can effectively prevent the chain drive-belt fracture, the drive sprocket reversing, thus the step reversing appears, the hidden danger of harm passenger safety.
The utility model is achieved in that the complementary mechanical brake of using on a kind of escalator and the automatic pedestrian path, and its special character is: it comprises ratchet, ratchet, connecting rod, travel switch and the sliding shoe assembly that is fixed on the drive sprocket;
Connecting rod one end cooperates with travel switch, the other end is captiveed joint with ratchet;
Ratchet is articulated on the truss by a support, ratchet and ratchet engaged under a certain state;
Sliding shoe assembly and assembly support articulate, and assembly support is fixed on the truss, and the sliding shoe assembly cooperates with driving chain; Travel switch is fixed on the assembly support; One hanged hook, one end is connected with slide assemblies, the other end is connected with connecting rod.
The complementary mechanical brake of using on described a kind of escalator and the automatic pedestrian path, its special character is: described sliding shoe assembly is made of sliding shoe, spring, spring pressure bar and spring bracket;
Sliding shoe is articulated on the assembly support, and with the driving chain bearing fit; Spring bracket is captiveed joint with assembly support; Spring pressure bar is captiveed joint with spring bracket is removable;
The upper end of spring cooperates with the spring pressure bar lower end, and the lower end of spring cooperates with sliding shoe;
The lower end and the sliding shoe of hanged hook fixed, upper end and connecting rod overlap joint.
The complementary mechanical brake of using on described a kind of escalator and the automatic pedestrian path, its special character is: screw thread is arranged on the spring pressure bar, pilot hole is arranged on the spring bracket, spring pressure bar passes pilot hole; There are two nuts to cooperate, spring pressure bar is fixed on the spring bracket with spring pressure bar.
The complementary mechanical brake of using on described a kind of escalator and the automatic pedestrian path, its special character is: the end that described connecting rod cooperates with travel switch is provided with flexure strip, and flexure strip cooperates with travel switch.
The complementary mechanical brake of using on described a kind of escalator and the automatic pedestrian path, its special character is: also comprise a buting iron, buting iron is fixed on the truss, and buting iron cooperates with connecting rod.
The complementary mechanical brake of using on a kind of escalator of the utility model and the automatic pedestrian path, owing to adopt such structure, when the driving chain chain rupture, (one) sliding shoe assembly has lost the bearing force of driving chain, rotates under axially under the pressure effect of spring; Meanwhile the hanged hook drivening rod moves downward; Ratchet is around axially going up motion, ratchet and ratchet engaged, so main shaft and drive sprocket stop operating, thereby the staircase stop motion.When (two) connecting rod moved downward, the steel disc of connecting rod one end touched travel switch, thereby travel switch sends the motion that electric signal stops other each parts of staircase.Thereby reach the assurance equipment safety operation, prevent that the step reversing from causing personal injury.
