Abstract
The utility model discloses a safety inspection operation device of an elevator. The safety inspection operation device comprises an upper inspection limit switch connected into an uplink operation signal branch in series, wherein the upper inspection limit switch is arranged on an upper switch frame of the elevator, when a carriage of the elevator runs to a position of the upper inspection limit switch, the upper inspection limit switch is triggered and is disconnected, so that the uplink operation signal branch is disconnected. Through setting the upper inspection limit switch, when top heights of some floors are not very high, the carriage is ascended to the position of the upper inspection limit switch, and is only descended other than ascended, so that an accident of a knock of a head of a maintainer in ceiling roof operation can be avoided, and safety of personnel is ensured.
Description
Technical field
the utility model relates to a kind of safety inspection handling device of elevator.
Background technology
in prior art, some building floor headroom height is not very high, and when car is up to top layer, car top, to the inadequate people's of distance on roof height, is easy to cause the service personnel head in the operation of sedan-chair top to be knocked like this, causes accident.
Summary of the invention
the purpose of this utility model is to provide a kind of safety inspection handling device of elevator, avoids occurring in the accident that the service personnel head of sedan-chair top operation is knocked.
for achieving the above object, the technical solution adopted in the utility model is: a kind of safety inspection handling device of elevator, comprise apparatus for examination and repair, elevator operating loop, be connected to upstream operation signal branch and downstream operation signal branch between described apparatus for examination and repair and described elevator operating loop, described safety inspection handling device also comprises the upper maintenance limit switch being connected in described upstream operation signal branch, on this, maintenance limit switch is arranged on the upper switch frame of elevator, at the cage operation of described elevator when overhauling the position of limit switch on described, can touch described upper maintenance limit switch, on this, maintenance limit switch disconnects, described upstream operation signal branch disconnects.
utilization due to technique scheme, the utility model compared with prior art has following advantages: in this safety inspection handling device, maintenance limit switch is set, like this at some floor headroom height while not being very high, car goes upward to the position of maintenance limit switch, cannot continue up, can only be descending, thereby the accident that the service personnel head of avoiding occurring in the operation of sedan-chair top is knocked, guarantees personnel's safety.
Accompanying drawing explanation
accompanying drawing 1 is schematic diagram of the present utility model;
accompanying drawing 2 is the schematic diagram that upper maintenance limit switch of the present utility model is arranged on switch frame.
The specific embodiment
below in conjunction with accompanying drawing, further set forth structure of the present utility model.
shown in Fig. 1-2, a kind of safety inspection handling device of elevator, comprise apparatus for examination and repair 2, elevator operating loop 1, be connected to upstream operation signal branch 3 and downstream operation signal branch 4 between apparatus for examination and repair 2 and elevator operating loop 1, be connected on the upper maintenance limit switch 5 in upstream operation signal branch 3, on this, maintenance limit switch 5 is arranged on the upper switch frame 6 of elevator, like this cage operation of elevator on while overhauling the position of limit switch 5, can touch upper maintenance limit switch 5, maintenance limit switch 5 on this is disconnected, upstream operation signal branch 3 disconnects, thereby car cannot be up, can only be descending.
on upper switch frame 6, increased upper maintenance limit switch 5, like this at some floor headroom height while not being very high, car goes upward to the position of maintenance limit switch 5, cannot continue up, thereby avoid occurring in the accident that the service personnel head of sedan-chair top operation is knocked, guarantee personnel's safety.
Claims (1)
