Abstract
The utility model relates to a kind of stair comb plate and lifts detecting device, belongs to staircase technical field, and when staircase normally runs, because rear fixed plate is compressed the pressure of spring, support front end does not contact with switch tentacle; When fishback snaps in foreign matter, under the effect of running and step, upwards lift rear guide groove base plate withstands pedestal lower end to horizontal rearward movement simultaneously, and travel(l)ing rest touches switch tentacle after axle makes left-hand revolution, and switch tentacle triggers travel switch thus makes staircase automatically stop ladder; After fishback resets, rear fixed plate resets under the effect of Compress Spring, thus travel switch resets, and staircase recovers normal and runs.Adopt this detecting device, between fishback and step, snap in foreign matter, shake-up travel switch that can be more accurately sensitive, makes staircase out of service, and the reaction time of whole device is short, reduces the damage to clipped object.
Description
Technical field
The utility model relates to a kind of stair comb plate and lifts detecting device, belongs to staircase technical field.
Background technology
Automatic staircase comb plate is arranged on the horizontal segment up and down of staircase, play the guiding role to the operation of stair step.The position often had an accident in escalator is comb and step junction, in order to ensure the normal operation of staircase, there is gap in fishback and step herein, and can clamp the finger of child and other foreign material herein and cause danger, present staircase is after fishback clips to foreign matter, can level move backward, then touch travel switch, make staircase stop ladder, the mobile power needing to apply is very large backward to make comb, and opening time is long, very macrolesion can be caused to clipped object.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of gap location at fishback and step, if enter foreign matter, then touches the stair comb plate that travel switch makes staircase out of service and lifts detecting device.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of stair comb plate lifts detecting device, comprise fishback and anti-ballistic rail, fishback is arranged on the lower position of anti-ballistic rail, described fishback is provided with guide groove, described anti-ballistic rail is provided with detecting device, described detecting device is by carrier base, travel switch, travel(l)ing rest and screw rod composition, described carrier base lower end is fixedly connected on anti-ballistic rail, described travel switch is fixedly mounted on the upper end of carrier base, described screw rod is fixedly mounted on anti-ballistic rail, described travel(l)ing rest is connected on carrier base by axle, and travel(l)ing rest can rotate around the axis, described travel(l)ing rest rear end is provided with rear fixed plate, described rear fixed plate is socketed in also can along screw slide on screw rod.
Further; described travel switch front end is connected with switch tentacle; switch tentacle can be sensitive the contact of crush stroke switch, when not having external force to interfere, switch tentacle has reset function, the button of travel switch can also be protected not damaged simultaneously.
Again further, described travel(l)ing rest comprises support front end and pedestal lower end, and described support front end outer side is fillet structure, adopts this structure can touch switch tentacle easily.Described pedestal lower end gos deep in guide groove, when fishback upwards lifts, promotes pedestal lower end and move up at the bottom of guide groove, whole travel(l)ing rest around axle left-hand revolution, support front end touching switch tentacle, and then crush stroke switch makes staircase out of service.
Further, described screw rod is socketed with Compress Spring, screw rod top uses bolt to regulate the tightness of Compress Spring, described Compress Spring bottom is pressed on rear fixed plate, adopt this structure when staircase normally runs, because rear fixed plate is compressed the pressure of spring, travel(l)ing rest front end does not contact with travel switch tentacle; After being resetted by staff after stair comb plate lifts, pedestal lower end loses the thrust of guide groove, and the pressure that rear fixed plate is compressed spring resets, and staircase normally runs.
Compared with prior art, usefulness of the present utility model is: between fishback and step, snap in foreign matter, and shake-up travel switch that can be more accurately sensitive, makes staircase out of service, and the reaction time of whole device is short, reduces the damage to clipped object.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is front view of the present utility model.
Fig. 2 is left view of the present utility model.
Fig. 3 is birds-eye view of the present utility model.
In figure: 1, fishback, 11, guide groove, 2, anti-ballistic rail, 3, carrier base, 4, travel switch,
41, switch tentacle, 5, travel(l)ing rest, 51, rear fixed plate, 52, support front end, 53, pedestal lower end, 6, screw rod, 7, Compress Spring, 8, axle.
detailed description of the invention:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
According to shown in Fig. 1 to Fig. 3, a kind of stair comb plate lifts detecting device, comprise fishback 1 and anti-ballistic rail 2, fishback 1 is arranged on the lower position of anti-ballistic rail 2, fishback 1 is provided with guide groove 11, described anti-ballistic rail 2 is provided with detecting device, described detecting device is by carrier base 3, travel switch 4, travel(l)ing rest 5 and screw rod 6 form, described carrier base 3 lower end is fixedly connected on anti-ballistic rail 2, described travel switch 4 is fixedly mounted on the upper end of carrier base 3, described screw rod 6 is fixedly mounted on anti-ballistic rail 2, described travel(l)ing rest 5 is connected on carrier base 3 by axle 8, and travel(l)ing rest 5 can rotate around axle 8, described travel(l)ing rest 5 rear end is provided with rear fixed plate 51, described rear fixed plate 51 is socketed on screw rod 6 and also can slides along screw rod 6.
Travel switch 4 front end according to Fig. 1 is connected with switch tentacle 41,
According to Fig. 1, travel(l)ing rest comprises support front end 52 and pedestal lower end 53, and be fillet structure outside support front end 52, pedestal lower end gos deep in guide groove 11.
According to Fig. 1, screw rod 6 is socketed with Compress Spring 7, screw rod 6 top uses bolt to regulate the tightness of Compress Spring 7, and Compress Spring 7 bottom is pressed on rear fixed plate 51.
During use, when staircase normally runs, because rear fixed plate 51 is compressed the pressure of spring 7, support front end 52 does not contact with switch tentacle 41; When fishback 1 snaps in foreign matter, under the effect of running and step, upwards lift rear guide groove 11 base plate withstands pedestal lower end 52 to horizontal rearward movement simultaneously, and travel(l)ing rest 5 touches switch tentacle 21 after 8 axles make left-hand revolution, and switch tentacle 21 triggers travel switch 4 thus makes staircase automatically stop ladder.After fishback resets, rear fixed plate 51 resets under the effect of Compress Spring 7, thus travel switch 4 resets, and staircase recovers normal and runs.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
