Fig. 2 is the structural representation of the present invention at step or the sagging state of pedal.
In accompanying drawing: the 1-steel rope; The 2-detector switch; 3-installs baffle plate; The 4-support ring; The 5-hinge; 6-re-packs; The 7-spring; The 8-spring dead plate; The 9-setting nut; The 10-pulling plug; The 11-baffle plate; The 21-switch contact.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
Refer to Fig. 1 and Fig. 2, the invention provides a kind of escalator or footway fender guard, it mainly comprises steel rope 1, detector switch 2, re-pack 6, spring 7 and spring dead plate 8.Described steel rope 1 is arranged in the below of step or pedal along the length direction of escalator or moving sidewalk, the one end is fixedly connected on escalator or moving sidewalk, its other end 6 is connected with described re-packing. and the outside that described detector switch 2 is arranged on described steel rope 1 is near described 6 the position of re-packing, in the present embodiment, detector switch 2 is positioned at the top of steel rope 1.Described escalator or footway fender guard also comprise a plurality of support rings 4 that are arranged on described step or pedal, and described steel rope 1 passes described support ring 4.A plurality of described support rings 4 are arranged at intervals on truss along the length direction of escalator or moving sidewalk.
Described detector switch 2 is arranged on the installation baffle plate 3 of the top of being located at described steel rope 1 and switch contact 21 exceeds described installation baffle plate 3, and the switch contact 21 of described detector switch 2 re-packs 6 towards described.In the present embodiment, described detector switch 2 is travel switch.
Described re-packing 6 is hinged on the outside of described detector switch 2 rotationally by hinge 5, and described detector switch 2 is positioned at described steel rope 1 and pulls described 6 radius of gyration scopes of rotating that re-pack.Described 6 the end of re-packing is the pin jointed end that is connected with hinge 5, and its other end is for rotating end, and described rotation end is free to rotate take described pin jointed end as rotating shaft, and described rotation end is connected with described spring 7.
Described spring dead plate 8 is fixedly installed on described 6 sides of rotating away from described detector switch 2 that re-pack, described spring 7 be connected to described re-pack 6 and described spring dead plate 8 between and strain and describedly re-pack 6 and steel rope 1.
Described escalator or footway fender guard also comprise that described the re-packing of restriction 6 touch the baffle plate 11 that is rotated further after described detector switch 2, and described baffle plate 11 is installed in the same side that is positioned at described detector switch in described 6 the radius of gyration scope of re-packing.
On described spring dead plate 8, also be provided with elastic adjusting mechanism, described spring 7 is fixedly connected on described elastic adjusting mechanism.Described elastic adjusting mechanism comprises the pulling plug 10 that is connected with described spring 7 and the setting nut 9 of regulating pulling plug 10 collapsing lengths, and described pulling plug 10 passes described spring dead plate 8 and is threaded with described setting nut 9.By rotation setting nut 9, can regulate the flexible of pulling plug 10, thus the elastic force of regulating spring 7.
As shown in Figure 1, under normal condition, step and pedal sink, and spring 7 will re-pack 6 and steel rope 1 tension, re-pack 6 away from detector switch 2.
Refer to Fig. 2; as shown by arrows; under the state that step or pedal sink; step or pedal drop on steel rope 1; steel rope 1 pressurized 6 produces pulling force to re-packing, and 6 elastic force that overcome spring 7 under the pulling of steel rope that re-pack clockwise rotate take the hinge 5 of pin jointed end as rotating shaft; re-pack and 6 get to touch switch contact 21 on detector switch 2, detector switch 2 actions send shutdown signal make escalator or moving sidewalk out of service.Re-pack 6 rotations until lower end is subject to stopping operating after stopping of baffle plate 11, and this moment, steel rope 1 can't continue to pull to re-pack 6, and step and pedal stop sinking.After step and pedal made progress homing, steel rope 1 and re-packing 6 was strained by spring 7 again, re-packed 6 to rotate counterclockwise away from detector switch 2, and detector switch 2 resets, and this moment, escalator and moving sidewalk can leave the normal operation of ladder.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
