Abstract
The invention discloses a safety device of an escalator or a moving walkway. The safety device comprises a motor flywheel, an electric brake chassis arranged below the motor flywheel, a locking piece and a safety switch which is arranged on the electric brake chassis, wherein the motor flywheel is provided with a first locking hole; and a position, which corresponds to the first locking hole, on the electric brake chassis is provided with a second locking hole. When the safety device is in the working state, the locking piece is inserted into the first locking hole and the second locking hole, the motor flywheel can be braked, the escalator or the moving walkway can be prevented from being started, the locking piece triggers the safety switch and the power supply of the escalator or the moving walkway can be cut off, so that safety hidden trouble caused when the power supply of the escalator or the moving walkway is forgotten to be cut off carelessly is eliminated and the safety of maintenance personnel is fully guaranteed; and when the safety device is in the non-working state, the locking piece is separated from the first locking hole, the second locking hole and the safety switch, and the escalator or the moving walkway can be restarted.
Description
Technical field
The present invention relates to the safety device of a kind of escalator or automatic walkway.
Background technology
Escalator or automatic walkway are widely used in places such as shopping square, airport and Railway station; Escalator or automatic walkway need regularly carry out repair and maintenance; Need make escalator or automatic walkway be in off-position at warranty period,, but possibly carelessness cause forgetting the power supply of closing escalator or automatic walkway sometimes with guarantee repair and maintenance personnel's personal safety; Then there is potential safety hazard, the safety device of the invention of therefore being born.
Summary of the invention
The purpose of this invention is to provide the safety device that fully guarantees the repair and maintenance personal security on a kind of escalator or the automatic walkway.
For achieving the above object; The technical scheme that the present invention adopts is: the safety device of a kind of escalator or automatic walkway; Comprise the motor flywheel, be arranged on the motor braking chassis of said motor flywheel below; Offer first lockhole on the said motor flywheel, said motor braking chassis with the corresponding position of said first lockhole on offer second lockhole, said safety device also comprises locking piece, is arranged on the safety switch on the said motor braking chassis; Said safety device has mode of operation and off working state; When said safety device was in running order, said locking piece was inserted in said first lockhole and said second lockhole, and said locking piece touches said safety switch; When said safety device was in off working state, said locking piece and said first lockhole and said second lockhole were separated, and said locking piece separates with said safety switch mutually.
Preferably, said motor braking fixedly is equipped with switch bracket on the chassis, and a side of said switch bracket is provided with said safety switch; Opposite side is provided with adapter plate; All offer mounting hole on said safety switch and the said adapter plate, be inserted with bolt in the said mounting hole, be combined with nut on the said bolt; Through cooperating of said bolt and said nut, said adapter plate and said safety switch are clamped on the said switch bracket.
Because the utilization of technique scheme, the present invention compared with prior art has advantage: through safety device is set, before repair and maintenance work begins; Locking piece is inserted in first lockhole and second lockhole; The braking motor flywheel can stop escalator or automatic walkway to start, and locking piece touches safety switch; Cut off the power supply of escalator or automatic walkway; Can eliminate like this since careless forget close the potential safety hazard that escalator or automatic walkway power supply cause, fully ensure repair and maintenance personnel's safety, behind the repair and maintenance end-of-job; Locking piece and first lockhole and second lockhole and safety switch are separated, can reactivate escalator or automatic walkway.
Description of drawings
Accompanying drawing 1 is in the scheme drawing of off working state for the present invention;
Accompanying drawing 2 is the in running order scheme drawing of the present invention.
The specific embodiment
Come further to set forth structure of the present invention below in conjunction with accompanying drawing.
Referring to illustrated in figures 1 and 2, the safety device of a kind of escalator or automatic walkway, comprise motor flywheel 1, be arranged on motor flywheel 1 below motor braking chassis 2, locking piece 3, be arranged on the safety switch 4 on the motor braking chassis 2; Motor flywheel 1 rotates escalator or automatic walkway power can be provided, and motor flywheel 1 is braked can stop using escalator or automatic walkway, offers first lockhole 5 on the motor flywheel 1; Motor braking chassis 2 with first lockhole, 5 corresponding positions on offer second lockhole 6, safety device has mode of operation and off working state, when safety device is in running order; As shown in Figure 2; Locking piece 3 is inserted in first lockhole 5 and second lockhole 6, through braking motor flywheel 1, can stop escalator or automatic walkway to start; And locking piece 3 touches safety switch 4; Cut off the power supply of escalator or automatic walkway, eliminated potential safety hazard, fully guaranteed warranty period repair and maintenance personnel's personal safety; When safety device was in off working state, the locking piece 3 and first lockhole 5 and second lockhole 6 were separated, and locking piece 3 separates with safety switch 4 mutually, and be as shown in Figure 1, and this moment is after repair and maintenance work is accomplished, but escalator or automatic walkway normal operation.To sum up, through safety device is set, before repair and maintenance work begins; Locking piece 3 is inserted in first lockholes 5 and second lockhole 6, and locking piece 3 touches safety switchs 4, can eliminate because carelessness is forgotten and close the potential safety hazard that escalator or automatic walkway power supply cause; Ensure repair and maintenance personnel's safety; Behind the repair and maintenance end-of-job, locking piece 3 is extracted, can reactivate escalator or automatic walkway.
The mounting means of safety switch 4 on motor braking chassis 2 is as shown in Figure 2, and the matching and fixing through bolts and nuts on the motor braking chassis 2 is equipped with switch bracket 7, and a side of switch bracket 7 is provided with safety switch 4; Opposite side is provided with adapter plate 8, all offers mounting hole on safety switch 4 and the adapter plate 8, and mounting hole has two; Be provided with up and down, be inserted with bolt 9 in the mounting hole, be combined with nut on the bolt 9; Cooperation through bolts and nuts; Adapter plate 8 is clamped on the switch bracket 7 with safety switch 4, that is to say, safety switch 4 is arranged on the motor braking chassis 2 through adapter plate 8 and switch bracket 7.On motor braking chassis 2, safety switch 4 is arranged on the below of second lockhole 6.Locking piece 3 can adopt bolt, and after bolt inserted first lockhole 5 and second lockhole 6, the tail end of bolt can touch safety switch 4.
To sum up, safety device of the present invention, simple in structure, easy to use, as long as locking piece is inserted in first lockhole and second lockhole, and after touching safety switch, can stop escalator or automatic walkway to start, ensure repair and maintenance personnel's personal safety.
