Based on an original structure of the escalator, the safe device is additionally provided with a base seat, the pressing rod and the safety switch, so that the function of escalator stopping and protection are achieved after the overhaul cover plate is opened. The safe device for opening the overhaul cover plate of the escalator is simple in structure and largely improves the reliability and safety of operation of the escalator.
Description
Technical field
The utility model relates to the access panel of escalator and opens safety device.
Background technology
The GB16899-2011 regulation, the access panel of escalator should arrange electric safety device up to specification, otherwise can cause safety misadventure.
Summary of the invention
The purpose of this utility model provides the access panel of escalator and opens safety device, and this safety device so that escalator is out of service, is protected maintainer and passenger's safety by safety switch after access panel is opened.
For achieving the above object, the technical solution adopted in the utility model is: a kind of access panel of escalator is opened safety device, comprise the access panel that can open or close, described access panel is opened safety device and is also comprised firm banking, be arranged on rotationally the depression bar on the described firm banking, be fixedly installed on the described firm banking and can after contact is touched, send the safety switch that stops described escalator operation signal, described access panel has open mode and closed condition, when described access panel is in closed condition, this access panel compresses the residence and states depression bar, so that the contact of this depression bar and described safety switch is separated, the contact of this safety switch is not touched; When described access panel is in open mode, loses the described depression bar of compressing of this access panel and under Action of Gravity Field power, rotate the contact that touches described safety switch.
Preferably, when described depression bar touched the contact of described safety switch, this depression bar struck on the described firm banking, and the position that is struck by described depression bar on this firm banking and described contact are in the same side of this depression bar.
Preferably, have the limiting section that the described depression bar of can conflicting is avoided this depression bar inordinate rotation on the shell of described safety switch, when described access panel was in closed condition, described depression bar was limited between described access panel and the described limiting section.
Preferably, described firm banking is arranged on the large angle steel of described escalator along the vertical direction movably, be provided with the detent mechanism for this firm banking of location between the large angle steel of this firm banking and described escalator, the rotational axis line of described depression bar is horizontally disposed with.
During implementation, described detent mechanism comprises perforation on the large angle steel that is opened on the described firm banking perforation of extending along the vertical direction, is opened in described escalator, pass the bolt of the perforation on the large angle steel of described firm banking and described escalator, the nut that matches with this bolt.
Because the utilization of technique scheme; the utility model compared with prior art has following advantages: the access panel of this escalator is opened in the safety device; after access panel is opened; depression bar rotates the contact that touches safety switch under Action of Gravity Field; the safety switch action makes staircase out of service, plays the effect of protection maintainer and passenger safety.This safety device adds upper bed-plate, depression bar and safety switch on the basis of staircase original structure just can realize that apparatus structure is simple, has greatly improved staircase reliability of operation and safety to the terraced protective effect that stops after opening access panel.
Description of drawings
Accompanying drawing 1 is scheme drawing one of the present utility model, and wherein access panel is in closed condition, and the contact of safety switch is not touched by depression bar;
Accompanying drawing 2 is scheme drawing two of the present utility model, and wherein access panel is in open mode, and depression bar touches the contact of safety switch.
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 1-2, a kind of access panel of escalator is opened safety device, the firm banking 1 on the large angle steel 3 that comprise the access panel 5 that can open or close, is arranged on escalator, rotationally be arranged on depression bar 6 on the firm banking 1, be fixedly installed on the firm banking 1 and can after contact 71 is touched, send the safety switch 7 that stops described escalator operation signal.Depression bar 6 is assemblies, is fixedly formed by a plurality of parts.Depression bar 6 is connected on the base 1 by bolts and nuts combination 4, and is gapped between depression bar 6 and the bolts and nuts combination 4, thereby so that depression bar 6 can rotate at base 1, the rotational axis line of depression bar 6 is horizontally disposed with.Safety switch 7 is fixed on the base 1 by bolts and nuts combination 8, is connected also fastening with bolts and nuts combination 2 between base 1 and the large angle steel 3, offer the oval hole of extending along the vertical direction on the base 1, such as Fig. 1-2, offer perforation on the large angle steel 3, bolt passes the oval hole of base 1 in the bolts and nuts combination 2, the perforation of large angle steel 3, screwed nut on the position that passes, realize the location of base 1 on large angle steel 3, if unscrew nut, height that then can up-down adjustment base 1 guarantees that the depression bar 6 on the base 1 is in suitable position, after adjusting puts in place, screw upper nut and get final product.Access panel 5 has open mode and closed condition, when access panel 5 is in closed condition, as shown in Figure 1, this access panel 5 compresses depression bar 6, so that the contact 71 of this depression bar 6 and safety switch 7 is separated, the contact 71 of this safety switch 7 is not touched, and this moment, escalator can normally move; When access panel 5 is in open mode, as shown in Figure 2, lose compressing of this access panel 5; depression bar 6 clickwise under Action of Gravity Field power touches the contact 71 of safety switch 7; safety switch 7 sends and stops the escalator operation signal, in time stops ladder, protection maintainer and passenger's safety.
When depression bar 6 rotations touch the contact 71 of safety switch 7, broken in order to prevent contact 71 from bearing excessive load, when depression bar 6 touches the contact 71 of safety switch 7, this depression bar 6 strikes on the firm banking 1, and, the position that is struck by depression bar 6 on this firm banking 1 and contact 71 are in the same side of this depression bar 6, as shown in Figure 2.
Has the limiting section that the depression bar 6 of can conflicting avoids this depression bar 6 excessively to rotate counterclockwise on the shell 72 of safety switch 7, like this when access panel 5 is in closed condition, as shown in Figure 1, depression bar 6 is limited between access panel 5 and the limiting section, the continuation rotation of the conter clockwise of restriction depression bar 6, play the effect of mechanical self-latching, prevent that safety device lost efficacy.
To sum up, the access panel of this escalator is opened in the safety device, and after access panel was opened, depression bar was subjected to action of gravitation to touch safety switch downwards by lever principle, and the safety switch action makes staircase out of service, plays protection maintainer and passenger safety.This safety device adds upper bed-plate, depression bar and safety switch just can be realized the terraced protective effect that stops after opening access panel on the basis of staircase original structure; apparatus structure is simple; self structure has again mechanical self-latching; have the functional characteristics such as protection safety switch, electric security protector; simultaneously also satisfy GB16899-2011 to the up-to-date technology requirement of staircase class safety switch, greatly improved staircase reliability of operation and safety.
