Abstract
The utility model discloses a lifting plate safety device of an escalator or an automatic moving pavement. The lifting plate safety device comprises a lifting plate and also comprises a supporting member, an impacting rod, a safety switch and an elastic member, wherein the lifting plate can be opened and closed; the supporting member is arranged on a truss of the escalator or the automatic moving pavement; the impacting rod is rotatably arranged on the supporting member; the safety switch is arranged on the supporting member and can send a signal for stopping the escalator or the automatic moving pavement after being triggered; the elastic member is arranged between the impacting rod and the supporting member and can provide elastic restoring force for the impacting rod; when being closed, the lifting plate overcomes the elastic restoring force and is conflict with the impacting rod, and the impacting rod does not trigger the safety switch, so that the normal operation of the escalator or the automatic moving pavement can be guaranteed; and when the lifting plate is opened, the conflict of the lifting plate is eliminated, and the impacting rod starts to rotate under the elastic restoring force of the elastic member, so that the safety switch is triggered and sends an operation stopping signal, the escalator or the automatic moving pavement can be stopped in time, and further the safety of passengers and maintainers is guaranteed.
Description
Technical field
the utility model relates to the boarding plate safety device of escalator or moving sidewalk.
Background technology
In
prior art; Boarding plate on escalator or the moving sidewalk is (like the normal operation time) that can open (like maintenance, when safeguarding) and close; When the boarding plate is opened; If escalator or moving sidewalk be normally operation still, carry passenger, then entail dangers to passenger, repair and maintenance personnel's safety.
Summary of the invention
safety device that escalator or moving sidewalk can be out of service in case the purpose of the utility model provides that the boarding plate is opened.
are for achieving the above object; The technical scheme that the utility model adopts is: the boarding plate safety device of escalator or moving sidewalk; Comprise the boarding plate that can open and close; Said boarding plate safety device also comprise strut member on the truss that is arranged on said escalator or moving sidewalk, rotationally be arranged on drop bar on the said strut member, be contained in and can after being touched, send the safety switch that stops said escalator or moving sidewalk run signal on the said strut member, be arranged on the elastic component that this drop bar elastic-restoring force can be provided between said drop bar and the said strut member; When closing said boarding plate; It is inconsistent that this boarding plate overcomes the elastic-restoring force and the said drop bar of said elastic component, and this drop bar does not touch said safety switch; When opening said boarding plate, said drop bar touches said safety switch under the elastic-restoring force of said elastic component.
preferably; The turning cylinder of said drop bar is fixed on the said strut member, offers on the said drop bar perforation is installed, and is set in rotationally on the said turning cylinder through the said drop bar of this installation perforation; Said elastic component adopts torsion spring; This torsion spring set is located on the said turning cylinder, and an end of this torsion spring is fixed on a side of said drop bar, and the other end is fixed on the said strut member; The axial elasticity back-up ring is housed on the said turning cylinder, and this axial elasticity back-up ring is blocked in the relative opposite side of said drop bar.
Preferably, the rotational axis line of said drop bar is horizontally disposed with
.
are because the utilization of technique scheme; The utility model compared with prior art has advantage: when closing the boarding plate; This boarding plate of elastic-restoring force and the drop bar that overcome elastic component are inconsistent; This drop bar does not touch safety switch, can guarantee the normal operation of escalator or moving sidewalk like this; After opening the boarding plate, lost the conflict of boarding plate, drop bar rotates under the elastic-restoring force of elastic component; Thereby shake-up safety switch; Send signal out of service, escalator or moving sidewalk in time stop, and guarantee passenger, repair and maintenance personnel's safety.
Description of drawings
Accompanying drawing 1 is for the master of the utility model looks scheme drawing, and wherein the boarding plate is closed on the frame;
Accompanying drawing 2 is the schematic side view of the utility model, and wherein the boarding plate is closed on the frame;
accompanying drawing 3 is for the master of the utility model looks scheme drawing, and wherein the boarding plate has been opened from frame.
The specific embodiment
The structure of the utility model is further set forth in
below in conjunction with accompanying drawing.
are referring to shown in Fig. 1-3; The boarding plate safety device of escalator or moving sidewalk; Strut member 1 on the truss 4 that comprise the boarding plate 9 that can open and close, is arranged on escalator or moving sidewalk, rotationally be arranged on drop bar 8 on the strut member 1, be contained in safety switch 3 on the strut member 1, be arranged on the elastic component 5 that these drop bar 8 elastic-restoring forces can be provided between drop bar 8 and the strut member 1, truss 4 is provided with frame 10, is used to carry boarding plate 9; When closing boarding plate 9; Boarding plate 9 is embedded in the frame 10, after opening boarding plate 9 from frame 10, and the inner space of exposing frame 10.Strut member 1 and drop bar 8 are positioned at the below of boarding plate 9; As illustrated in fig. 1 and 2, be fixed with adapter plate 2 on the strut member 1, be fixed with the turning cylinder 7 of drop bar 8 on the adapter plate 2; Offer on the drop bar 8 perforation is installed; Be set in rotationally on the turning cylinder 7 through this installation perforation drop bar 8, turning cylinder 7 is roughly along the horizontal direction setting, thus the rotation up and down of realization drop bar 8.Elastic component 5 adopts torsion spring, and this torsion spring set is located on the turning cylinder 7, and is as shown in Figure 2; One end of this torsion spring is fixed on a side of drop bar 8; The other end is fixed on the adapter plate 2 of strut member 1, and realizing provides drop bar 8 elastic-restoring forces, and axial elasticity back-up ring 6 is housed on the turning cylinder 7; This axial elasticity back-up ring 6 is blocked in the relative opposite side of drop bar 8, thereby forbids that drop bar 8 splits away off from turning cylinder 7.When closing boarding plate 9; Elastic component 5 is compressed, and this boarding plate 9 of elastic-restoring force that overcomes elastic component 5 is inconsistent with drop bar 8, and this drop bar 8 keeps separating with safety switch 3; Perhaps drop bar 8 contacts with safety switch 3; But do not touch safety switch 3, as illustrated in fig. 1 and 2, can guarantee the normal operation of escalator or moving sidewalk like this; After opening boarding plate 9; As shown in Figure 3, lost the conflict of boarding plate 9, drop bar 8 rotates under the elastic-restoring force of elastic component 5; Thereby touch safety switch 3; Send signal out of service, escalator or moving sidewalk in time stop, and guarantee passenger, repair and maintenance personnel's safety.This boarding plate safety device is simple in structure, easy for installation, uses reliably, plays the safety precaution effect.
