Definitions

  • the present invention relates to a work device for carrying out assembly or maintenance work in an elevator shaft.
  • Multi-story assembly platforms are known specifically to enable work to be carried out in an upper area of an elevator shaft. That's how she beats EP1647512 proposed installing an assembly platform with an upper and a lower platform. This allows work to be carried out in a higher shaft area or on the shaft ceiling by climbing the upper platform.
  • the GB 2,452,269 A shows a lightweight assembly platform that is to be installed in a stationary manner in the shaft and that is extended upwards and has at least one ladder or another platform.
  • the present invention is intended to provide an alternative device for carrying out work in a higher shaft area of an elevator shaft.
  • the work device is designed to be able to carry out assembly or maintenance work in an elevator shaft.
  • the work device consists at least of a work platform with a standing surface and a railing, the standing surface offering space for at least one person and the railing at least partially enclosing the standing surface.
  • the work device further comprises at least one additional platform.
  • This additional platform is designed such that it is or can be attached to the railing of the work platform and the Additional platform offers an additional standing area for at least one person, the additional standing area in the assembled state, that is to say when it is attached to the railing, being above the railing.
  • the advantage here is that the assembly platform, which is designed for working in the area of a shaft access, preferably in the area of an uppermost shaft access, can be easily expanded in order to enable work in a higher shaft area.
  • the additional standing surface of the additional platform is arranged above the railing and viewed from the standing surface of the work platform at least partially, but advantageously essentially or even completely outside the railing.
  • the advantage here is that the actual footprint of the work platform can be kept rather small. It is matched, for example, to the width of a shaft opening. However, this creates distances to the side walls on the side of the work platform. Because the additional standing area of the additional platform can be arranged at least partially outside the railing or outside the standing area of the work platform, the distance to the side walls can be reduced, which enables safe working in the areas of the shaft walls. In an advantageous solution, a position of the additional standing area of the additional platform can be shifted in relation to the work platform. This means that it is possible to react flexibly to the respective dimensions of the elevator shaft.
  • the additional platform has a fence which essentially encloses the additional standing area and serves as a fall protection.
  • the advantage here is that a worker who steps onto the additional platform is protected from being able to fall into the elevator shaft. This enables safe work.
  • the fence has an access gate, which is advantageously designed to be self-closing.
  • the advantage here is that a worker who is on the additional platform is protected all around so that he cannot fall in the direction of the access.
  • a self-closing access gate which must be consciously opened to enter and exit, for example by lifting a handrail and which automatically closes again after deliberate opening, the safety of work is particularly high, since the gate does not close after stepping on the additional platform can be forgotten.
  • the additional platform has an access, preferably a ladder, which is assembled with the additional platform.
  • the ladder enables the additional stand area to be entered from the work platform.
  • the advantage here is that no separate ladder or the like is required to reach the additional platform.
  • the boarding does not have to be sought, it is inevitably integrated into the additional platform. This eliminates improvising and further reduces the risk of accidents.
  • the additional platform can be hung on the railing of the work platform. Suspended here means that the additional platform is held on the railing, but loading forces, in particular vertical loading forces, can be introduced into the railing or, for example, can also be introduced directly into the work platform. In this respect, the additional platform can also be placed on the railing of the work platform.
  • the advantage here is that the additional platform can be attached as required. It does not have to be permanently installed, but can be hung or placed on the railing in the desired working positions if necessary. The additional platform thus does not hinder other applications of the working platform.
  • the additional platform can be locked on the railing of the work platform by means of a lock after it has been suspended.
  • the locking includes a self-closing bolt which automatically locks the additional platform after it has been attached to the railing.
  • the Locking by means of a locking pin, a locking pin or the like.
  • the lock preferably includes a clearly visible feature which indicates the locked state (locked or unlocked).
  • the advantage here is that the additional platform cannot be accidentally unhooked. This also increases the safety of use of the additional platform.
  • the additional platform can be moved on the railing.
  • a shift can take place without the additional platform having to be unhooked.
  • the additional platform can be moved sideways.
  • the overall advantage here is that the additional platform can easily be moved quickly, at least along a straight railing section. In this way, for example, a fastening or adjustment can be carried out in a rear area of the elevator shaft and then the additional platform can be moved forward so that work can be carried out in the area of a front side wall of the elevator shaft.
  • the displaceability enables the additional platform to be arranged at desired working positions.
  • the additional platform comprises a support which is attached to the additional standing area, preferably to an outer area of the additional standing area, and which supports the additional standing area on the work platform.
  • a load on the railing can primarily be reduced by means of such a support, which enables the railing itself to be made lighter. This is of course inexpensive and facilitates assembly of the railing itself.
  • the support is preferably preassembled, for example, on the additional platform, so that it can be pivoted or shifted into a support position.
  • the working device comprises two additional platforms, the two additional platforms being or being attached to opposite sides of the working platform.
  • the additional platforms are preferably identical, i.e. they can basically be attached anywhere on the railing.
  • the advantage here is that, for example, two people can work on opposite sides of the elevator shaft at the same time or can assemble a component in the elevator shaft together.
  • the work platform of the work device is a preferably temporary assembly platform, which is arranged in the elevator shaft, preferably in the area of an uppermost shaft opening, for carrying out assembly work.
  • the additional platform is arranged on the railing of this work platform in order to carry out work in a head area of the elevator shaft.
  • the work platform is designed, for example, as in the application EP3631119 by the same applicant. This application is filed at the same time as the present application and its content can also be read.
  • the EP3631119 relates to a temporary assembly platform as a work platform for assembling elevator equipment in an elevator shaft, a method for assembling such an assembly platform and a method for adapting such an assembly platform.
  • the proposed assembly platform is designed in particular to be arranged essentially in the region of a shaft opening, so that the assembly platform rests partially on a floor surface on the building side and partially protrudes into the elevator shaft.
  • the assembly platform comprises a floor frame and floor panels which are placed on or inserted into the floor frame.
  • the floor frame further includes two side floor supports, at least one front and one rear cross member, which connect the two side floor supports to one another, and further at least two intermediate supports, which are arranged parallel to the two side floor supports.
  • the two intermediate beams are essentially supported by the front and rear cross members.
  • This temporary assembly platform is designed to interact in particular with an assembly carrier, which assembly carrier is suitable for suspending elevator loads or assembly devices.
  • guide rails are to be arranged in an elevator shaft, which are later to be used for guiding an elevator car and a counterweight. In many cases this is done in the area of the shaft ceiling Aids, such as an installation kit, are installed, which enable such guide rails to be arranged precisely.
  • the additional platform can now be used advantageously for the arrangement of such an aid. With this, for example, alignment or plumb lines can be placed and aligned. The additional platform enables an assembly team to safely reach the required fastening and adjustment points and the members of the assembly team can move around in a safe environment at all times.
  • Such a work device can, however, be used in a variety of ways. It can be temporarily installed and used for repairs in the elevator shaft. With a corresponding configuration of a railing of an elevator car, the additional platform can also be mounted on a railing of the elevator car in order, for example, to carry out repairs or cleaning work in a shaft head area of the elevator system.
  • Figure 1 shows an additional platform 10 for a work platform 1.
  • the work platform 1, together with the additional platform 10, forms a work device for carrying out work in an elevator shaft.
  • the standing area 5 of the work platform 1 is dimensioned so that at least one person can stand and work on it.
  • the work platform 1 can be an assembly platform in an elevator shaft, which is temporarily installed, for example, for the assembly of shaft equipment and so on, or it can analogously also be a roof structure of an elevator car (not shown), which has a standing area 5 for performing control or service work in the Has elevator shaft.
  • the work platform 1 is at least partially enclosed by a railing 6, 6u in order to offer the person working on the work platform a safety against falling.
  • the work platform 1 with standing surface 5 and railings 6, 6u is in Figure 1 shown schematically in dashed lines.
  • the additional platform 10 includes an additional standing area 13, which is dimensioned such that a person can usually stand and work on it.
  • the additional standing area 13 is arranged above the railing 6 of the work platform 1.
  • the additional standing area 13 of the additional platform 10 is also designed such that, viewed from above, it is arranged essentially outside the railing 6. It thus forms a work surface which protrudes laterally over the standing surface 5 of the work platform 1 and which is arranged above the railing 6.
  • the additional platform can also be designed (not shown) in such a way that it is only partially arranged outside the railing and, on the other hand, is arranged above the standing surface 5 of the work platform 1 when viewed from above.
  • the additional standing area 13 of the additional platform 10 has a fence 16.
  • the enclosure 16 encloses the additional standing area 13 on the three sides projecting away from the work platform 1 and thus prevents a person working on the additional standing area 13 from falling into an elevator shaft.
  • the fence 16 has several fence posts 17, 17z which, in the example, are placed on holders on the additional standing surface 13 and fixed there by means of a retaining pin 19.
  • the additional standing area 13 also has a foot protection strip 18. This also protects the person standing on the additional stand area 13.
  • the additional platform 10 includes a boarding 11 in the form of a ladder 12.
  • the boarding 11 enables the additional standing area 13 to be climbed.
  • a handrail 15 is also arranged on the fence post 17z on the approach side. The handrail 15 primarily serves to make it easier to climb onto the additional standing area 13, but it can also serve to attach a safety rope, which additionally secures the person working on the work platform 1 or the additional platform 10.
  • the additional platform 10 can be hung on the railing 6 of the work platform 1 via the access 11.
  • the additional platform 10 can be secured by means of an upper securing device 22.
  • the upper securing device 22 can be a clamping screw or it can 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 inadvertent lifting of the additional platform 10 from the railing 6.
  • a lower holder 24 is arranged on the approach 11, which, as explained in connection with the upper holder 21, is used to hang the additional platform 10 on the railing 6.
  • a lock 20 is also attached in the area of the lower holder 24.
  • the lock 20 secures the additional platform 10 against accidental unhooking.
  • the lock 20 is arranged in the area of the lower holder 24; it could of course also be in the area of the upper holder 21.
  • the lock 20 is based on Figure 3 explained in more detail.
  • the locking device 20 comprises a bolt 25 as a central element.
  • the bolt 25 is attached to the access 11 or the ladder 12 via a pivot point 29.
  • the latch 25 has a hook 25h at its lower end. Because of gravity the bolt 25 hangs down in principle and is designed in such a way that the hook 25h is suspended below the lower cross strut 6u of the railing 6.
  • the hook 25h is beveled on an end surface 25e opposite a locking surface 25v, so that the bolt 25 is pushed back when the additional platform 10 is placed on the railing 6, 6u and again after it has been placed on, which is determined by the lower bracket 24 falls into its position determined by gravity and thus the additional platform 10 is essentially automatically locked.
  • the inevitable locking can be reinforced by a spring as required.
  • the lock 20 can also be secured.
  • a locking pin 26 is provided, which is inserted through a structural part of the access 11 and the locking bar 25 and is fixed by means of a locking device 27.
  • An independent further fuse in the form of a lower fuse 28 is also shown.
  • the lower fuse 28 can be made identical to the upper fuse 22, as described above.
  • the security measures shown can of course, as shown, be used together or individually.
  • the additional platform 10 can be placed on the railing 6 at a desired working position.
  • the additional platform can also be moved lengthways on the railing by loosening the clamping screws or bolts.
  • the longitudinal shift is at least as simple as possible, as there are no railing posts. In the area of a railing post, the additional platform 10 may only need to be raised briefly.
  • a work platform 1 is equipped with two additional platforms 10 and together form a work device for carrying out assembly or maintenance work in an elevator shaft 4.
  • the additional platforms 10 are in the example on both sides of the work platform 1, or on opposite sides of the work platform 1 on the respective railings 6 put on and secured.
  • the railing 6 generally also includes a rear railing 7.
  • the rear railing 7 can also serve as a basis for the arrangement of the additional platform 10 with a corresponding configuration.
  • the support 40 shown is supported on the work platform 1.
  • the support 40 is via a support bracket 41 (see also Figure 2 ) slidably attached to the outer area of the additional standing surface 13 and it can be moved down in the support holder 41 (direction of arrow 43) so that it is supported on the work platform 1 or on a support bracket 44 provided in the area of a floor frame 30 of the work platform 1.
  • securing measures are also provided here, for example by means of support securing means 42, which secure the support 40 against inadvertent loosening.
  • supports 40 for example at least two supports 40, can of course be used at the two outer corner points of the additional standing area 13.
  • the work device formed by the work platform 1 and at least one additional platform 10 can now, as in FIG Figure 5 can be used to carry out assembly work in the elevator shaft.
  • the device is arranged as a temporary assembly platform or assembly platform in the area of an uppermost shaft opening 3.
  • the work platform 1 is fastened to the building structure by means of posts 8 and rests partially on a floor surface 2 on the building side via the floor frame 30.
  • the work platform 1 is also held in the elevator shaft 4 by means of an additional cable safety device 35.
  • the additional platform 10 is placed on the railing 6 of the work platform 1 and, as described in the previous explanations, is fixed and secured.
  • a so-called installation kit 39 is arranged in the uppermost area of the elevator shaft 4.
  • This exemplary installation kit is used as an assembly jig for aligning guide rails, shaft doors and other items.
  • This installation kit 39 can be fastened as high as possible in the elevator shaft by means of the additional platform 10.
  • FIG 5 only a single additional platform 10 can be seen. In practice, two additional platforms 10 could also be used in this application, as in connection with FIG Figure 2 explained.
  • the installation kit 39 can be lifted together and fastened in the appropriate position in the elevator shaft.
  • the work device consisting of work platform 1 and at least one additional platform 10 is suitable for carrying out work in a head area of the elevator shaft in a simple and safe manner.
  • barriers 38 On the post 8 are in the embodiment of Figure 5 further barriers 38 attached. These prevent inadvertent stepping on the work platform 1.
  • the barriers 38 can at best be provided with warning signs that warn against stepping on the work platform. Locks can also be provided on the barriers 38, which only allow them to be removed with the appropriate key.
  • FIG 6 a different or supplementary application of the work device consisting of work platform 1 and additional platform 10 is shown in a different constellation.
  • the work platform 1 itself is penetrated by an assembly support 36 which is arranged in the elevator shaft 4.
  • the standing area 5 remains on the work platform and the additional platform 10 can also be arranged laterally on the railing 6 of the work platform 1, which further enables work to be carried out in an upper shaft area.
  • the additional platform 10, or its additional standing area 13, can still be reached via the boarding 11 from the work platform.
  • the railing of the work platform 1 naturally also includes the rear railing 7.
  • the rear railing 7 can be designed essentially identical to the side railing 6.
  • the additional platform 10 can also be arranged on the rear railing 7.
  • the working platform 1 for its part comprises the floor frame 30 and floor plates which define the standing surface 5 of the working platform 1.
  • the base plates are placed on the base frame 30 or are inserted into it.
  • the floor frame 30 further includes two lateral floor supports 31, at least one front 33 and one rear cross member 34, which connect the two lateral floor supports 31 to one another, and further at least two intermediate supports 32, which are arranged parallel to the two lateral floor supports 31.
  • the two intermediate carriers 32 are essentially carried by the front and rear cross members 33, 34 and they are spaced from one another so far that the assembly carrier 36 can be passed between them.
  • the work platform is connected to the structure on the building side via posts 8.
