Abstract
The invention discloses a safe locking device of an escalator. The escalator is correspondingly in the overhauling state when being overhauled, at this moment, a motor stops, an inserting rod is inserted into a through hole of a flywheel and triggers a switch, then a safety loop of the escalator is powered off, as a result, the escalator is powered off, the stair loop is prevented from rotating, accidents are avoided, and the security in overhauling is improved; and when the overhauling is completed and the escalator can work normally, the escalator is correspondingly in the normal state, and the inserting rod is fallen off from the through hole of the flywheel and the switch, so that the motor can output power normally, the switch is returned, the safety loop is closed, and the escalator is powered on and can work normally.
Description
?
Technical field
The present invention relates to a kind of safe locking device of escalator.
?
Background technology
In the prior art, when escalator overhauled, the step loop should be slack, but in some cases, malfunction has occured in the step loop, causes having an accident.
?
Summary of the invention
The safe locking device that the purpose of this invention is to provide a kind of escalator when the maintenance escalator, disconnects safety return circuit by this safe locking device, makes escalator be in off-position, guarantees that the step loop is motionless, thus the safety when guaranteeing maintenance.
For achieving the above object, the technical solution used in the present invention is: the safe locking device of escalator, comprise the flywheel on the escalator drive motor, be opened in the perforation on the radial surface of described flywheel, inserted link, be arranged on the stay bearing plate on the shell of described motor, be arranged on the switch on the described stay bearing plate, described switch series is in the safety return circuit of escalator, described escalator has inspecting state and normal condition, when described escalator is in inspecting state, described inserted link inserts in the perforation of described flywheel, and described inserted link touches described switch, so that described safety return circuit disconnects described escalator outage; When described escalator was in normal condition, described inserted link broke away from perforation and the described switch of described flywheel, and described switch resets, and described safety return circuit is closed, described escalator energising.
A kind of concrete embodiment, described switch is positioned at the below of described stay bearing plate, and described flywheel is positioned at the top of described stay bearing plate, offers the perforation that can supply described inserted link to pass on the described stay bearing plate.
Described inserted link is hex bolt.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages: this safe locking device is set, then when the maintenance escalator, is in inspecting state corresponding to escalator, this moment, motor was slack, inserted link is inserted in the perforation of flywheel, and the inserted link touch switch, so that the escalator safety return circuit disconnects, thereby escalator outage, guaranteed that the step loop can not rotate, avoided having an accident, the safety when having improved maintenance; Complete when maintenance, when escalator can normally move, be in normal condition corresponding to escalator, the perforation and the switch that inserted link are broken away from flywheel, the so normal outputting power of motor, and also switch resets, safety return circuit is closed, and the escalator energising can work.
?
Description of drawings
Accompanying drawing 1 is schematic diagram of the present invention.
?
The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Referring to shown in Figure 1, the safe locking device of escalator, comprise flywheel 2 on the escalator drive motor, be opened in perforation, inserted link 1 on the radial surface of flywheel 2, be arranged on stay bearing plate 3 on the shell of motor, be arranged on the switch 5 on the stay bearing plate 3, switch 5 strings are in the safety return circuit of escalator, in Fig. 1, inserted link 1 adopts hex bolt.When the maintenance escalator, be in inspecting state corresponding to escalator, this moment, motor was slack, inserted link 1 is inserted in the perforation of flywheel 2, and inserted link 1 touch switch 5, so that the escalator safety return circuit disconnects, thereby escalator outage, guaranteed that the step loop can not rotate, avoided having an accident, the safety when having improved maintenance; Complete when maintenance, when escalator can normally move, be in normal condition corresponding to escalator, the perforation and the switch 5 that inserted link 1 are broken away from flywheel 2, the so normal outputting power of motor, and also switch 5 resets, safety return circuit is closed, and the escalator energising can work.
In Fig. 1, switch 5 is contained in the below of stay bearing plate 3 by switch bracket 4, flywheel 2 is positioned at the top of stay bearing plate 3, offers perforation on the stay bearing plate 3, like this when the maintenance escalator, the perforation that inserted link 1 inserts flywheel 2, after the perforation of passing stay bearing plate 3, arrive switch 5 places, touch switch, so that staircase is in off-position, guarantee the safety of maintenance.
