Description
Technical field
The present invention relates to a kind of device that is used to guarantee in lift well, to carry out the upkeep operation personal security, wherein carry out upkeep operation and service personnel and when elevator moves, face threat from the danger of vertical shaft equipment from the top of the lift car that in lift well, moves.
Background technology
In EP 0 926 093, disclosed a kind of elevator, wherein carried out the upkeep operation in the lift well from the lift car top with the lift car that in lift well, moves.The vertical projection projection of elevator drive equipment that is arranged on the vertical shaft top is in the vertical projection of lift car.When elevator car arrives top layer section, the service personnel on the lift car top might be sandwiched between elevator car roof and the elevator drive equipment.As safety measure with for fear of the generation of accident, the railing that utilization is arranged on the car roof limits the domain of walk on car roof, wherein can walk with the scope of railing beyond the area of conter of reserving elevator drive equipment on the car roof and the elevator drive equipment area of conter on car roof.
The shortcoming of this known devices is that though only just need limit in the top layer section, in fact the domain of walk at any story height car top all has been subjected to restriction.
Summary of the invention
The objective of the invention is to propose a kind of device that the service personnel that carries out upkeep operation in lift well is protected, wherein overcome the shortcoming that exists in the existing device.
At this a kind of ancillary method is proposed.The implementation of the object of the invention is: a kind of device that is used to guarantee to carry out the personal security of upkeep operation in lift well; wherein upkeep operation is carried out and service personnel will face the danger that vertical shaft equipment causes when elevator cage operation in the top of the lift car that moves in the lift well; it is characterized in that fender guard is arranged on the vertical shaft equipment and will makes lift car out of service when having accident hazard.
According to further design of the present invention, fender guard is a fender, and described fender avoids service personnel to be sandwiched between vertical shaft equipment and the lift car.
According to further design of the present invention, fender is made of a casing and the cover cap that is arranged on the casing that can swing that is arranged on the vertical shaft device carrier, and wherein the position to cover cap monitors.
According to further design of the present invention, be provided with the sensor that is used to monitor the trigger position of cover cap and is used to monitor its open position.
According to further design of the present invention, a limit spring is set on casing, described limit spring is used for cover cap being remained on the normal position and realizing cover cap moving to end position.
According to further design of the present invention, limit spring be Z-shape and with the cover cap fastener on hole interlocking.
The advantage that the present invention realized mainly is, only just the domain of walk of car top is limited at dangerous section.When car is positioned at other position the walking of car top be unrestricted fully and therefore service personnel can utilize car top fully, thereby be convenient to carry out upkeep operation and improve upkeep operation efficient at car top.Only when the walking at whole carriage top is unrestricted, could carry out upkeep operation to the guide rail that stretches in whole shaft height.This equally also is applicable to by the upkeep operation of vertical shaft side to the floor door.In addition, the whole top of car top also can be used for installing escape hatch.
