Abstract
The utility model discloses a safe locking device of an escalator. The safe locking device of the escalator comprises a flywheel arranged on a driving motor of the escalator, a punched hole formed in the radial surface of the flywheel, an inserted rod, a supporting plate arranged on an outer shell of the motor, and a switch arranged on the supporting plate, wherein the switch is connected in a safety circuit of the escalator in series. When the escalator is repaired, the safe locking device is in a repairing state correspondingly, the motor keeps still at the moment, the inserted rod is inserted into the punched hole in the flywheel and triggers the switch to enable the safety circuit of the escalator to be disconnected, and then the escalator is powered off, a step circuit will not rotate, accidents are avoided, and safety is guaranteed in a repairing process. When the repairing is finished and the escalator can operate normally, the safe locking device is in a normal state correspondingly, the inserted rod is made to be separated from the punched hole of the flywheel and the switch so that the motor can output power normally, the switch returns to the original position, and the safety circuit is closed to enable the escalator to be powered on for normal work.
Description
Technical field
The utility model 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 taken place in the step loop, causes having an accident.
Summary of the invention
The purpose of this utility model provides a kind of safe locking device of escalator, when the maintenance escalator, disconnect safety return circuit by this safe locking device, make escalator be in off-position, guarantee that the step loop is motionless, thus the safety when guaranteeing maintenance.
For achieving the above object, the technical solution adopted in the utility model 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, make described safety return circuit disconnect, described escalator outage; When described escalator was in normal condition, described inserted link broke away from the perforation and the described switch of described flywheel, and described switch resets, described safety return circuit closure, 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 a hex bolt.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: 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, make the escalator safety return circuit disconnect, thereby escalator outage, guaranteed that the step loop can not rotate, avoided having an accident, the safety when having improved maintenance; When maintenance finishes, when escalator can normally move, be in normal condition corresponding to escalator, inserted link is broken away from the perforation and the switch of flywheel, the normal outputting power of motor like this, and also switch resets, the safety return circuit closure, the escalator energising can normal operation.
Description of drawings
Accompanying drawing 1 is a scheme drawing of the present utility model.
The specific embodiment
Further set forth structure of the present utility model 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, make the escalator safety return circuit disconnect, thereby escalator outage, guaranteed that the step loop can not rotate, avoided having an accident, the safety when having improved maintenance; When maintenance finishes, when escalator can normally move, be in normal condition corresponding to escalator, inserted link 1 is broken away from the perforation and the switch 5 of flywheel 2, the normal outputting power of motor like this, and also switch 5 resets, the safety return circuit closure, the escalator energising can normal operation.
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, make staircase be in off-position, guarantee the safety of maintenance.
