Definitions
- the invention relates to a device for executing Working in an elevator shaft with shortened Shaft head, in which elevator shaft a counterweight and an elevator car with a maintenance platform can be moved from executable from maintenance work on shaft equipment are.
- a disadvantage of the known device is that the cabin wall supporting the platform is mechanically reinforced must be and also fittings for folding and locking of the pedestal are necessary on which the elevator users get caught with clothing or objects because the platform is in the lounge area of the Elevator user is located.
- the invention seeks to remedy this.
- the invention as characterized in claim 1, solves the problem to avoid the disadvantages of the known device and a facility for working in an elevator shaft too create that neither for the maintenance staff nor for the Elevator users in the elevator car pose a danger.
- the advantages achieved by the invention are in essential to see that for the Elevator car users are at no risk of sticking to parts to injure the maintenance platform because the maintenance platform itself outside the lounge area of the Elevator car users on the roof of the elevator car located.
- the cabin interior is through the maintenance platform not affected. This is sales strategy aesthetic presentation of the cabin interior of large economic importance.
- the maintenance platform comes this Requirement for example through the invisible arrangement completely opposite the maintenance platform.
- the maintenance platform also has an increased load capacity, so in the shaft too assembling or disassembling parts on the maintenance platform can be stored temporarily.
- the location of the maintenance platform on the roof of the elevator car can be chosen so that the maintenance platform is not arranged in the shaft head Shaft equipment is towered over, the maintenance platform has a sufficiently large footprint.
- the location, the sufficient footprint and increased load capacity of the Maintenance platform ensure the safety of the Maintenance personnel.
- the use of the Cabin roofs necessary as a maintenance platform Safety device extremely easy to use and quickly operational without any effort.
- Another advantage is that during maintenance work the inside of the cabin, in particular the cabin walls are not scratched or be damaged because the maintenance platform is not in the Elevator car is located. With an elevator shaft with shortened shaft head is the safety of the Maintenance personnel also in a maintenance position of the Elevator cabin below the top floor guaranteed.
- FIG. 1 A machine room-less elevator is shown in FIG. 1.
- 1 is a limited by shaft walls 1.1 Designated elevator shaft, in which an elevator car 2 and a counterweight 3 can be moved.
- a traction sheave 5 is arranged with a drive, not shown, is connected.
- the Traction sheave 5 and / or the drive is, for example, from worn on a wall or ceiling bracket.
- Has a suspension cable 6 a rope course, for example, from a first fixed point 6.1 via two deflection rollers 6.2, 6.3 of the elevator car 2, further over the traction sheave 5, further over a Deflection roller 6.4 of the counterweight 3 and on to one second fixed point 6.5.
- the roof of the elevator car is a maintenance platform 10 trained, from which maintenance staff 11 work in Can execute elevator shaft 1, such as Maintenance work on traction sheave 5, guide rails, Shaft switch, drive, suspension cable 6, etc.
- Elevator car 2 and counterweight 3 are in two different locations shown. With a broken line the elevator system is shown in normal operation, the Elevator car 2 on the top floor 1.3 with the corresponding lowest position of the counterweight 3 barely is shown standing over a buffer device 12.
- the elevator system is in full service operation shown.
- the machine room-less elevator system shown offers with its shortened shaft head 4 for maintenance from the canopy 2.1 not enough height H for one legal crossing Ü (distance between Canopy 2.1 and shaft ceiling 1.2) of, for example one meter.
- Ü distance between Canopy 2.1 and shaft ceiling 1.2
- the counterweight 3 When the elevator car 2 is empty, the counterweight 3 is opposite the eye cabin 2 overweight and can become pulling the elevator car 2 down at the same time move. Without safety device 13 there is a risk that that the counterweight 3 except for the buffer device 12 lowered and located on the maintenance platform 10 Maintenance personnel 11 due to the shortened shaft head 4 endangered. With the safety device 13 is the way of the counterweight 3 limited to a height that the required crossing Ü between canopy 2.1 and Manhole cover 1.2 is guaranteed in every case.
- the safety device 13 has a first Design variant a monitored, height adjustable Support 13.1, for example by means of a spindle 13.2 is adjustable in height.
- the spindle 13.2 is one Motor 13.3 driven.
- the one intended as a route limitation Safety device 13 is activated as follows: If the elevator car 2 at most on the second uppermost Floor 1.4 stands, the motor 13.3 by means of a Elevator control AS and by means of a first switch 13.4 be turned on in the upward direction. The support 13.1 moves upwards until a first limit switch 13.5 is operated, which opens a first contact 13.51, one second contact 13.52 closes and the motor 13.3 off. The support 13.1 is now in the for Crossing Ü correct security position. Then it will Counterweight 3 by means of elevator control AS and drive slowly lowered until a second, the location of the support 13.1 detecting limit switch 13.7 by means of Counterweight 3 is operated.
- the second limit switch 13.7 opens a third contact 13.71, causing the Elevator drive is switched off.
- the counterweight 3 lies on the support 13.1, the elevator car 2 not can move up further.
- the elevator car 2 is now secured against any further upward movement.
- the Working in elevator shaft 1 can now be done safely be carried out.
- the elevator car 2 is at least on the second uppermost Floor 1.4 lowered and the engine 13.3 by means of Elevator control AS and by means of a second switch 13.8 switched in the downward direction.
- the support 13.1 moves until it moves out of the way of the counterweight 3 is in normal operation.
- Fig. 2 shows a serving as a safety device 13 manual support 13.1 that in the path of the Counterweight 3 is manually pivotable. With interrupted The rest position of the support 13.1 is shown in the line is monitored by means of limit switch 13.7 and contact 13.71. Normal operation of the elevator system is only in the rest position of the Support 13.1 possible. So that the security of the Maintenance personnel 11 is guaranteed in any case can be provided a further limit switch, the Working position of the support 13.1 monitored.
- the support 13.1 is pivotable about a pivot point D1 and along a Support 13.11 adjustable in height.
- the manual support 13.1 can also on the shaft wall 1.1 be screwable or for example in the shaft wall 1.1 arranged anchor rails can be suspended.
- Fig. 3 shows a serving as a safety device 13 Height-adjustable buffer device consisting of buffer 12 and lifting device 12.1.
- the buffer is used 12 in the working position shown as a support 13.1.
- the Working position of the buffer 12 is by means of limit switches 13.7 and contact 13.71 and the rest position of the buffer 12 by means of Limit switch 13.9 and contact 13.91 monitored and if exceptional operating conditions are detected, the elevator control AS switches the elevator system off.
- the lifting device 12.1 the scissors principle. It can be manual or motorized or be drivable by means of cylinders and pressure medium.
- the Lifting device 12.1 can also be telescopic, for example be constructed.
- the above-mentioned safety device 13 can instead on the counterweight side in the cabin head 4 to be ordered.
- 13 also a device for extending the suspension cable 6 be provided.
- the facility at least postpones a fixed point 6.1.6.5 downwards. Through the Displacement of the fixed rope point from the shaft ceiling 1.2 the effective suspension cable length is increased away. With an extended suspension rope 6, the regulations Crossing Ü are observed because the elevator car 2 in the upper end position is less high.
- the suspension cable extension can also be moved at least the traction sheave 5 can be reached downwards.
