Summary of the invention
The object of the invention provides a kind ofly touches earlier non-automatic reset switch and securing rod is inserted in cage fixture mechanism in the lockhole again.
For achieving the above object, the technical solution used in the present invention is: a kind of cage fixture mechanism of elevator, comprise the permanent seat that is arranged on the elevator car frame, be arranged on the adapter plate on the cage guide, be slidingly arranged in the securing rod on the described permanent seat, be opened in the lockhole that matches with described securing rod on the described adapter plate, described securing rod has mode of operation and off working state, when described securing rod is in running order, described securing rod is inserted in the described lockhole, when described securing rod is in off working state, described securing rod and described lockhole are separated, described permanent seat is provided with non-automatic reset switch, described securing rod is provided with touch part, when described securing rod from off working state to the mode of operation switching process, described touch part touches described non-automatic reset switch.
Preferably, described touch part comprises and is arranged on described securing rod away from the shake-up sheet on the end of described lockhole, described shake-up sheet bends towards described non-automatic reset switch, be formed for touching the kink of described non-automatic reset switch, when described securing rod was in off working state, described kink arrived the distance of described lockhole less than a described securing rod end relative with described lockhole to the distance of described non-automatic reset switch.
Preferably, have fixed block on the described permanent seat, described fixed block offers through hole along the direction of slip of described securing rod, and described securing rod passes described through hole slidably.
Preferably, described adapter plate is arranged on the outside of described cage guide, the inner side edge of described cage guide is provided with the pressure guide plate, one side compressing of described pressure guide plate is on the inner side edge of described cage guide, also have part to be pressed on the described adapter plate on the described pressure guide plate, described adapter plate and described pressure guide plate clamp described cage guide.
Described permanent seat is arranged on the upper beam of described elevator car frame.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage: overhaul at car, in the time of need being fixed on car on the guide rail, promote securing rod, the touch part on the securing rod touches non-automatic reset switch, and securing rod just can be inserted in the lockhole then, like this when car with respect to guide rail fixedly the time, elevator must be in off-position, has avoided securing rod to be fractureed, and has eliminated potential safety hazard.
Description of drawings
Accompanying drawing 1 is looked scheme drawing one for master of the present invention, and wherein securing rod is inserted in the lockhole;
Accompanying drawing 2 is looked scheme drawing two for master of the present invention, and wherein securing rod and lockhole are separated;
Accompanying drawing 3 is inserted in schematic top plan view in the lockhole for securing rod among the present invention, and shows elevator hoistways;
Accompanying drawing 4 be among Fig. 2 B to scheme drawing.
The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Referring to Fig. 1-shown in Figure 4, a kind of cage fixture mechanism of elevator, comprise the permanent seat 1 that is arranged on the elevator car frame 3, be arranged on the adapter plate 4 on the cage guide 2, be slidingly arranged in the securing rod 5 on the permanent seat 1, be opened in the lockhole 6 that matches with securing rod 5 on the adapter plate 4, permanent seat 1 can be arranged on the upper beam 11 of elevator car frame 3, securing rod 5 has mode of operation and off working state, when securing rod 5 is in running order, securing rod 5 is inserted in the lockhole 6, this moment, car was fixed with respect to guide rail, when securing rod 5 is in off working state, securing rod 5 is separated with lockhole 6, can remove fixing between car and the guide rail this moment, permanent seat 1 is provided with non-automatic reset switch 7, securing rod 5 is provided with touch part 8, when securing rod 5 from off working state to the mode of operation switching process, touch part 8 touches non-automatic reset switch 7.Overhaul at car, in the time of need being fixed on car on the guide rail, promote securing rod 5, touch part 8 on the securing rod 5 touches non-automatic reset switch 7, securing rod 5 can be inserted in the lockhole 6 then, and when car with respect to guide rail fixedly the time, elevator must be in off-position like this, avoid securing rod to be fractureed, eliminated potential safety hazard.
