Abstract
The invention discloses an escalator step loss safety device, comprising a horizontal section of a pedal return rail fixedly arranged at the two ends of the escalator, a support piece close to a rotary part of the escalator, a stopping piece which is rotatably arranged on the support piece and can be contacted with the side of the step, an elastic piece which is arranged between the support piece and the stopping piece and can provide an elastic restoring force to drive the stopping piece to rotate when the step is lost and a safety switch which is arranged on the support piece, can be triggered by a rotary stopping piece and then sends out an escalator operation stopping signal. When the step is lost, the stopping piece is driven to rotate by virtue of the elastic restoring force of the elastic piece, the rotary stopping piece can trigger the safety switch, and the safety switch sends out the escalator operation stopping signal, thus the escalator stops and the life and property safety of passengers is guaranteed.
Description
Technical field
The present invention relates to escalator step loss safety device.
Background technology
At present, escalator is widely used in the places such as large-scale shopping square, airport and Railway station, and escalator is running in the situation of step loss, if still normally operation can cause occupant's danger.
Summary of the invention
The purpose of this invention is to provide on the escalator when step loss occurs so that staircase safety device out of service.
For achieving the above object, the technical solution used in the present invention is: escalator step loss safety device comprises that the pedal that is fixedly installed on described escalator two ends returns the rail horizontal segment at the strut member at the revolution position of close this escalator, rotation is arranged on the abutment that can conflict on the described strut member on the step side, being arranged on can provide described abutment elastic-restoring force between described strut member and the described abutment so that drive the elastic component that described abutment is rotated when step loss, be arranged on the described abutment shake-up that can be rotated on the described strut member and then send the safety switch that stops described escalator operation signal.
Preferably, described abutment comprises the upper block that can conflict on described step side, the lower block that can touch described safety switch, described upper block, described lower block fix setting, has recess on the outside face of described lower block, when block is stably conflicted on described step side on described, the contact of described safety switch is arranged in described recess, and does not contact with described lower block; Step loss can't with described on block when contacting, touch the contact of described safety switch by the described lower block of the elastic-restoring force of described elastic component.
Further preferably, described elastic component adopts a pair of spring, described abutment also comprises the attaching parts that fixes setting with described upper block, described lower block, the dual-side of described attaching parts lays respectively at the both sides of the rotational axis line of described abutment, the dual-side of this attaching parts respectively and be provided with described spring between the described strut member, when the stable conflict of described abutment was on described step side, a described spring was in extended state, and the described spring of another one is in compressive state.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages: when step occurs to lose, elastic-restoring force by elastic component, the driving abutment is rotated, the abutment of rotating can be touched safety switch, so that safety switch sends the signal that stops escalator operation, thereby escalator is out of service, ensure passenger's the security of the lives and property, when the step normal presence, the elastic resistance by elastic component is so that abutment is stable conflicts on strut member, at this moment, safety switch is not touched, and elevator normally moves.
Description of drawings
Accompanying drawing 1 returns the rail horizontal segment at the scheme drawing at the revolution position of close this escalator for the pedal that the present invention is contained in the escalator end;
Accompanying drawing 2 is looked scheme drawing, not shown safety switch for master of the present invention;
Accompanying drawing 3 is schematic side view of the present invention;
Accompanying drawing 4 is the schematic top plan view of the lower block among the present invention.
The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Shown in Fig. 1-4, escalator step loss safety device, comprise strut member 2, rotation is arranged on the abutment 1 that can conflict on the strut member 2 on step 4 sides, be arranged on the elastic component 9 between strut member 2 and the abutment 1, be arranged on the safety switch 3 on the strut member 2, the pedal that strut member 2 is fixedly installed on the escalator two ends returns the rail horizontal segment at the revolution position near this escalator, elastic component 9 can provide abutment 1 elastic-restoring force, rotate so that when step 4 is lost, drive abutment 1 by elastic-restoring force, the abutment 1 of rotating can be touched safety switch 3, so that safety switch 3 sends the signal that stops escalator operation, like this in case step loss occurs, touch safety switch 3 by abutment 1, thereby escalator is out of service, ensures passenger's the security of the lives and property.
In Fig. 2 and 3, abutment 1 comprises the upper block 5 that can conflict on step 4 sides, can touch the lower block 6 of safety switch 3, attaching parts 8, upper block 5, lower block 6, attaching parts 8 fixes setting, the dual-side of attaching parts 8 lays respectively at the both sides of the rotational axis line of abutment 1, the dual-side of this attaching parts 8 respectively and be provided with spring 8 between the strut member 2, when step 4 normal presence, a spring 8 is in extended state, another one spring 8 is in compressive state, elastic resistance by two springs 8, force abutment 1 stable the conflict on step 4 sides, this moment, lower block 6 did not contact with safety switch 3, specifically, and in Fig. 4, has recess 7 on the outside face of lower block 6, when upper block 5 was stably conflicted on step 4 sides, the contact of safety switch 3 was arranged in recess 7, and did not contact with lower block 6, be that safety switch 3 is not touched, elevator normally moves; When step 4 losses can't contact with upper block 5, then under the elastic-restoring force effect of two springs 8, abutment 1 rotated, namely descend link stopper 6 to rotate, so that lower block 6 touches the contact of safety switch 3, after safety switch 3 is touched, send corresponding signal, so that elevator is out of service.
