Definitions

  • the present invention relates to a working device for performing assembly or maintenance work in a hoistway.
  • Assembly platforms are already used today for the installation of elevator equipment in a lift shaft. Specifically, to enable working in an upper area of a hoistway, multi-level erection platforms are known. Thus, EP1647512 proposes to install a mounting platform with upper and lower platforms. This allows work to be carried out in a higher shaft area or on the shaft ceiling by climbing the upper platform.
  • Such a mounting platform is difficult and expensive to assemble.
  • GB 2 452 269 A shows a lightweight mounting platform which is to be installed in a stationary manner in the shaft and which is extended upwards and has at least one ladder or a further platform.
  • the present invention is intended to provide an alternative means of performing work in a higher shaft area of a hoistway.
  • the working device is designed to be able to carry out assembly or maintenance work in a lift shaft.
  • the working device consists at least of a working platform with a standing surface and a railing, the standing surface providing space for at least one person, and the railing at least partially enclosing the standing surface.
  • the working device comprises at least one additional platform. This additional platform is designed so that it can be attached to the railing of the work platform or can be attached and the Additional platform provides an additional stand space for at least one person, the additional stand area in the mounted state, that is, when it is attached to the railing, above the railing.
  • the assembly platform which is designed for working in the region of a shaft access preferably in the region of a top shaft access, is easily expandable to allow work in a higher shaft area.
  • the additional floor space of the additional platform above the railing and viewed from the footprint of the working platform is at least partially, but advantageously substantially or even arranged entirely outside the railing.
  • the actual footprint of the work platform can be kept rather small. It is tuned, for example, to a width of a shaft opening. As a result, however, distances to side walls are created laterally of the work platform.
  • the fact that the additional footprint of the additional platform can be arranged at least partially outside the railing, or outside the footprint of the work platform, the distance to side walls can be reduced, whereby safe working is also possible in the areas of the shaft walls.
  • a position of the additional floor space of the additional platform with respect to the work platform can be moved.
  • the additional platform has a barrier, which essentially encloses the additional floor space and serves as fall protection.
  • the barrier has an access gate, which is advantageously self-closing. It is advantageous that a worker who is located on the additional platform is completely protected, so that he can not fall in the direction of access.
  • self-closing access gate which thus must be opened to enter and leave, for example, by raising a balustrade and self-closing after deliberate opening, safety of working is particularly high, since closing the gate after entering the additional platform not can forget.
  • the additional platform has an approach, preferably a ladder, which is assembled with the additional platform.
  • the ladder allows access to the additional floor space from the work platform.
  • the additional platform can be suspended on the railing of the work platform. Hinged in this case is to be understood that the additional platform is held on the railing, but loading forces, in particular vertical load forces, can be introduced into the railing or, for example, can be introduced directly into the work platform.
  • the additional platform can also be placed on the railing of the work platform.
  • the additional platform can be installed as needed. So it does not have to be permanently installed, but it can be hung on demand at desired working positions on the railing or even placed. Thus, the additional platform does not hinder other applications of the work platform.
  • the additional platform on the railing of the work platform can be locked after hanging by means of a lock.
  • the lock includes a self-closing latch, which automatically locks the additional platform after hanging on the railing.
  • the latch includes a clearly visible feature indicating the latch state (latched or unlocked).
  • the additional platform can not be accidentally posted. Also this increases a safety of use of the additional platform.
  • the additional platform is displaceable on the railing.
  • a shift can take place without the additional platform would have to be posted.
  • by releasing the lock sideways shifting of the additional platform may be possible.
  • the additional platform can easily be moved quickly at least along a straight railing piece.
  • an attachment or adjustment in a rear area of the hoistway can be carried out and then the additional platform can be moved forward, so that work in the area of a front side wall of the hoistway can be performed.
  • the displaceability allows arranging the additional platform at desired working positions.
  • the additional platform comprises a support, which is attached to the additional floor space, preferably on an outer area of the additional floor space, and which supports the additional footprint on the work platform.
  • the support is pre-assembled, for example, on the additional platform so that it can be pivoted or moved to a support position.
  • the working device comprises two additional platforms, wherein the two additional platforms can be attached to or attached to opposite sides of the work platform.
  • the additional platforms are identical, that is, they can basically be mounted anywhere on the railing. It is advantageous that, for example, two people on opposite sides of the hoistway can work simultaneously or together can assemble a component in the hoistway.
  • the working platform of the working device is a preferably temporary assembly platform, which is arranged to carry out assembly work in the elevator shaft, preferably in the region of an uppermost shaft opening.
  • the additional platform is arranged on the railing of this work platform to perform work in a head area of the hoistway.
  • the work platform is designed, for example, as described in application IP2457EP by the same Applicant. This application is filed concurrently with the present application and is to be read in content.
  • the IP2457EP relates to a temporary mounting platform as a work platform for mounting elevator equipment in a hoistway, a method of mounting such a mounting platform, and a method of adapting such a mounting platform.
  • the proposed assembly platform is in particular designed to be arranged substantially in the region of a shaft opening, so that the assembly platform partially rests on a building-side floor surface and partially protrudes into the elevator shaft.
  • the assembly platform includes a floor frame and floor panels which are placed on the floor frame or inserted into this. Further, the floor frame includes two lateral floor beams, at least one front and one rear cross member connecting the two side floor beams together, and further at least two intermediate beams arranged parallel to the two side floor beams.
  • the two intermediate carriers are essentially supported by the front and the rear cross member.
  • This temporary mounting platform is designed to interact in particular with a mounting bracket, which mounting bracket is suitable for attaching elevator loads or mounting devices.
  • Next guide rails are to be arranged in an elevator shaft, which are to be used later for guiding an elevator car and a counterweight.
  • Auxiliaries such as an installation kit, mounted, which allows a precise arrangement of such guide rails.
  • the additional platform can now be used advantageously for the arrangement of such an aid. This can be used, for example, to place and align rifle or cords.
  • the additional platform allows an assembly team to safely reach the required mounting and setpoints and the members of the assembly team move around in a safe environment at all times.
  • the additional platform can also be mounted on a railing of the elevator car in order to carry out, for example, repairs or cleaning work in a shaft head area of the elevator installation.
  • FIG. 1 shows a view of an additional platform with attachment to a working platform
  • FIG. 2 shows a view of a working device with working platform and two additional platforms
  • FIG. 3 shows a detailed view of a locking of the additional platform on the railing of the working platform

  • the footprint 5 of the work platform 1 is sized so that at least one person can stand and work on it.
  • the work platform 1 may be a mounting platform in an elevator shaft, which is temporarily installed, for example, for the installation of manhole equipment and so on or it may also be a roof structure of an elevator car (not shown), which has a footprint 5 for performing inspection or service work in the Elevator shaft has.
  • the work platform 1 is at least partially enclosed by a railing 6, 6u in order to provide the person working on the work platform with security against falling.
  • the working platform 1 with base 5 and railing 6, 6u is shown schematically in dashed lines in Figure 1.
  • the additional platform 10 includes an additional floor space 13, which is dimensioned so that usually a person can stand and work on it.
  • the additional floor space 13 is arranged above the railing 6 of the work platform 1.
  • the additional floor space 13 of the additional platform 10 is also designed such that, viewed from above, it is arranged substantially outside the railing 6. It thus forms a work surface which projects laterally beyond the standing surface 5 of the work platform 1 and which is arranged above the railing 6.
  • the additional platform can also be configured (not shown) such that it is only partially arranged outside the railing and, viewed from above, is arranged above the standing surface 5 of the work platform 1.
  • the additional floor space 13 of the additional platform 10 has a reinforcement 16.
  • the reinforcement 16 encloses the additional floor space 13 on the three sides projecting away from the work platform 1 and thus protects a person working on the additional floor space 13 from falling into an elevator shaft.
  • the reinforcement 16 has a plurality of protective posts 17, 17z, which in the example are plugged onto holders on the auxiliary stand surface 13 and fixed there by means of a holding pin 19.
  • the additional floor space 13 also has a Schaucheology 18. This also protects the standing on the additional floor space 13 person.
  • the additional platform 10 includes a boarding 11 in the form of a ladder 12.

The handrail 15 is primarily for easier climbing the additional floor space 13, but it can also serve to attach a safety rope, which additionally secures the person working on the working platform 1 or the additional platform 10 person.
  • the additional platform 10 can be hung on the railing 6 of the working platform 1.
  • an upper bracket 21 which serves to mount the additional platform 10 on the railing 6.
  • the upper fuse 22 may be a clamping screw or it may be a bolt that fits into an opening provided in the railing. In principle, the bolt can also be pushed through below the railing and thus counteract an accidental lifting of the additional platform 10 from the railing 6.
  • a lower support 24 is arranged on the approach 11, which, as explained in connection with the upper bracket 21, the hanging of the additional platform 10 on the railing 6 is used.
