Description
Technical Field
The invention relates to an arrangement for installing an elevator, in particular a cantilever elevator, in a hoistway and a bracket for engaging two elevator guide rail sections.
Background
When installing elevators in a shaft, it is desirable to provide a safe and efficient means for moving a temporary platform on which a construction worker can stand through the shaft.
US 8,186,130B 2 discloses such a method for installing an elevator. Here, after mounting into position in the lowermost guide rail section, at least one working platform is established between the guide rails of the lowermost guide rail section. The guide rail of the second guide rail section is then fixed as an extension of the guide rail of the lowermost guide rail section using the work platform as an aid. Here, the diverting pulley is fixed to the top end of the guide rail of the second guide rail section, the hoisting device and the rope suspension of the work platform are fitted to the work platform, in which rope suspension the hoisting rope is passed over the diverting pulley from the hoisting device at its first end and guided under the diverting pulley connected to the work platform to its fixing point of the second end and the work platform, and the work platform is lifted by the hoisting device to the next working level and locked in place.
The method comprises a relatively complex mechanism for lifting the work platform between the work positions. Furthermore, it is not suitable for guide rails provided for cantilever-type elevators.
Disclosure of Invention
It is therefore an object of the present invention to further optimize the installation equipment of a cantilevered elevator in a shaft, particularly in a shaft of a high-rise building.
The invention provides a device for installing a cantilever type elevator in an elevator shaft, which comprises:
two first guide rail sections mounted in a first section of the elevator hoistway, the two first guide rail sections extending parallel to each other in the vertical direction defining a constant horizontal distance therebetween,
a mounting device comprising a working platform adapted to engage the two first rail sections for guided movement along the two first rail sections,
a first horizontally extending bracket adapted to engage two first rail sections above the mounting device,
-a winch mechanism adapted to engage the bracket and the mounting device, and
-a winch mechanism for lifting the mounting device along the first rail section in an upward direction towards the carriage.
The invention also provides a mounting arrangement for mounting between two parallel extending guide rail sections of an elevator, in particular a cantilevered elevator, the mounting arrangement comprising a working platform adapted to engage with the guide rail sections, and a winch mechanism adapted to interact with and lift the working platform along the guide rail sections, the carriage extending horizontally between the two guide rail sections vertically above the working platform, the winch mechanism comprising a rope or chain extending between the carriage and the working platform. Advantageously, the rope or chain is provided as a single rope or chain.
The invention also provides a bracket adapted to engage and move along two parallel extending guide rail sections of an elevator, particularly a cantilevered elevator, which bracket is adapted to temporarily prevent downward movement along the guide rail sections.
Advantageously, the bracket is adapted to prevent downward movement in the event that a torque generated by a downward force acts on the bracket.
It is also possible to provide the carriage with a safety gear adapted to allow a downward movement along the rail section only in case the safety gear is actuated by a user.
With the present invention, an efficient means of installing a cantilevered elevator in a hoistway is provided. In particular, no special scaffolding has to be provided, since the rail or rail section is used for this purpose.
A particularly advantageous aspect of the invention is a bracket adapted to engage two parallel extending guide rail sections. Such a carriage may be moved upwards along a first guide rail section and then along a successive subsequent guide rail section. In particular, a torque is generated by applying a downward force on the bracket, by which the bracket is fixed in a position immovable downward as long as the torque is generated.
In the present description, the term guide rail section is used for a component of a guide rail. I.e. a plurality of vertically extending and aligned guide rail sections constitutes the entire guide rail. Two parallel guide rails are provided. The term "first guide rail section" particularly refers to the lowermost guide rail section of the guide rail. The "two first guide rail sections" are therefore in particular the respective lowermost sections of the two parallel-running guide rails.
Advantageous embodiments of the invention are the subject matter of the dependent claims.
According to a preferred embodiment of the invention, when the vertical distance between the mounting device and the bracket reaches a predetermined value, in particular a minimum value, two further guide rail sections are provided, which are each aligned with one of the two first guide rail sections and are mounted in another section of the elevator hoistway directly above the first section of the elevator hoistway, after which the further guide rail sections are each mounted in another section of the elevator hoistway
Any one of the following
-providing a further horizontally extending bracket adapted to engage a further rail section vertically above the mounting device,
-thereafter, arranging the winch mechanism to engage the further bracket and the mounting device, and actuating the winch mechanism to further lift the mounting device in an upward direction along the further rail section,
-or
-thereafter, moving the first carriage up the first rail section to engage with the further rail section, then further up the further rail section, thereafter engaging the first carriage with the further rail section in a non-downwardly movable manner, and actuating the winch mechanism engaged with the first carriage and the mounting device to lift the mounting device further up the further rail section.
The invention thus provides, inter alia, two alternative methods for installing an elevator, one method using various different mounting brackets provided along the length of the elevator hoistway and the other method using brackets that can be displaced along guide rail sections.
It will be apparent that the method of the present invention can be used for any desired rail length by providing additional rail sections, installing them in alignment with previously installed rail sections and repeating the above steps.
Advantageously, the mounting device can only be moved vertically downwards along the rail section or the entire rail, if the user specifically actuates the safety device. The provision of such a safety device ensures safe operation of the mounting device. For example, even if the winch mechanism fails, the safety device can ensure that the mounting device stays safely in place at its current position in the elevator hoistway and cannot accidentally move downward.
According to a preferred embodiment of the mounting device according to the invention, the safety device is provided on or at the work platform and is adapted to engage the guide rail section or the guide rail such that in a first operating state in which the safety device is not actuated by a user, the work platform can only be moved in an upward direction along the guide rail by means of the winch mechanism, and in a second operating state in which the safety device is actuated by a user, the work platform can be moved in a downward direction along the guide rail. The work platform can only be moved downwards if at the same time the rope of the winch mechanism is released and the safety device is activated.
Advantageously, the safety device comprises a blocking device which allows the work platform to move only in case the active blocking device is actuated. The blocking means advantageously comprise a compression spring which, unless decompressed by active actuation by the user, interacts with a roller arranged in a conical opening of the safety device.
Advantageously, the mounting device comprises a balancing mechanism adjusted to release two safety devices simultaneously, each safety device interacting with one of the two guide rail sections. For example, each security device may include a compression spring and a Bowden cable (Bowden cable). The counterbalance mechanism connects the two bowden cables such that pulling the counterbalance mechanism by a pulling motion acting on the two bowden cables causes the two compression springs to decompress at the same time.
Advantageously, the bracket comprises two openings or holes adapted to engage and move along two parallel extending rail sections and to prevent downward movement along the rail sections in the event of a torque being applied thereto resulting from a downward force, the two openings or holes being shaped to substantially correspond to the profile of the engaged rail sections, and a further opening or hole adapted to be engaged by the winch mechanism. As long as the winch mechanism does not exert a downward force on such a carriage, it can be displaced along the rail section. In this mode, the area of the opening is substantially perpendicular to the extension direction of the guide rail. When a downward force, which generates a torque, acts on the bracket, it pivots in the forward direction, so that the area of the opening is inclined with respect to the direction of extension of the guide rail section. Thereby, a movement along the guide section is effectively prevented.

Detailed Description
In fig. 1, the mounting device is generally designated 100. It includes a work platform 110 on which at least one person can stand.
The mounting device is further provided with a railing 120, which is only partially shown. The balustrade 120 serves to protect a person working on the mounting device from falling off.
On two opposite sides, the working platform 110 is attached to a vertically extending carrier 130. On each carrier 130, a safety device 140 is mounted. Each safety device 140 includes a U-shaped profile that is adapted and arranged to interact with a T-shaped rail section 200 of a cantilevered elevator system. The U-shaped profile includes a central channel 144 that tapers in an upward direction, as particularly shown in fig. 3. This means that the mounting device 100 is arranged between two parallel guide rail sections 200 (as shown in particular in fig. 2) and can be displaced along these guide rail sections 200 (as will be explained below).
As is shown in particular in fig. 3, which shows a part of a T-shaped rail section 200 and a safety device 140 in more detail, the safety device 140 is provided with a blocking device, in particular a positive blocking means (positive blocking means) 150. This active blocking device 150 ensures that the mounting device can only be moved along the rail section 200 in an upward direction, which is indicated by arrow U in fig. 2, without a specific unlocking action by the user. The active blocking means comprises a roller 142 arranged in a tapered channel 144 provided on the safety device 140. As shown in fig. 3, roller 142 is located between one side 201a of web 201 of rail 200 and tapered wall 144a of tapered channel 144. The roller 142 is driven upward (i.e., in the direction of arrow U) toward the narrow section of the tapered channel 144 by a guided and compressed spring 146 attached to a block 148 that engages the roller 142. This means that safety device 140 can only move in an upward direction without specifically decompressing spring 146. The interaction of the rollers 142 with the narrow section of the tapered channel 144 blocks downward movement.
In order to enable the safety device 140 and thus the mounting device as a whole to be moved down the rail section 200, a bowden cable 160 is provided which is attached to the spring 146. With the Bowden cable 160 pulled in the direction of arrow P, the spring 146 decompresses such that the roller 142 will move downward within the tapered channel 144. As long as the pulling of the bowden cable 160 in the direction of arrow P is maintained, the safety device and thus the mounting device can be moved down the rail 200.
Referring back to fig. 1, the location of the compression spring 146 and bowden cable 160 throughout the mounting device can be seen. As can be seen in particular from fig. 1, two bowden cables 160 are provided, one for each safety device, each cable interacting with one of the two guide rail sections. The ends 160a of the two bowden cables are connected to each other by a balancing device 170, which can be easily actuated by a person standing on the platform 110. If, for example, a person standing on the platform 110 pulls the counterbalance apparatus 170 vertically upward (i.e., in the direction of arrow Q), this motion results in pulling both bowden cables simultaneously, thereby releasing the active blocking device (i.e., the spring 146) so that the mounting device can move down the guide rail 200.
As can be seen in fig. 3, the active blocking arrangement greatly enhances the safety of a person on the platform 110. If, for example, the bowden cable 160 tears or breaks, the spring 146 automatically assumes its blocking position, i.e. blocks the roller 142 in the tapered channel 144.
A preferred method of installing a cantilevered elevator will now be described with reference to the various installation stages shown in fig. 4. The various stages are denoted a) to e).
In stage a), at least one horizontally extending support 410 is mounted to the borehole wall 400. Advantageously, two horizontally extending brackets 410 are mounted at a suitable vertical spacing from each other.
Also in stage a), two vertically extending rail sections 200 (two first rail sections in the language used above and in the claims) are mounted to the bracket 410. The two first guide rail sections 200 mounted to the same shaft wall 400 thus function as guide rail sections of a cantilevered elevator.
Thereafter, the mounting device 100 is mounted between the two first guide rail sections 200, as explained above with particular reference to fig. 1 and 2.
The bracket 470 is then engaged with the two first guide rail sections 200. The bracket 470 is shown in detail in fig. 5. It is provided with two openings 470a, the distance between which corresponds to the horizontal distance of the first guide rail section 200. Furthermore, the shape of the opening 470a corresponds to the contour of the first guide rail section 200. Thus, the bracket 470 may engage the rail section 200, wherein the rail section extends through the opening 470a and moves along the rail section in a vertical direction. Here, the area of the opening 470a extends in a plane perpendicular to the vertical extension of the rail section.
The bracket 470 is also provided with a second opening 470b for engagement with a winch mechanism, as will be explained below.
Returning to fig. 4, stage a), the winch mechanism 430 is engaged with the bracket 470 and the mounting device 100. The winch mechanism 430 is provided with a single cable or chain 440 and is adapted to engage the bracket 470 and the mounting device 100, for example, with suitable attachment means on the platform 110.
The force acting on the bracket 470 by the winch mechanism 430 engaging the opening 470b causes the bracket 470 to pivotally move forward relative to the first guide rail section 200, as indicated by arrow P shown in fig. 4a and 5. This results in preventing any vertical movement of the bracket 470 relative to the guide rail section 200. In other words, upon application of a force in a downward direction near the opening 470b, a torque is generated and the bracket 470 is temporarily prevented from moving along the first rail section 200.
By actuating the winch mechanism 430, the mounting device may then be pulled up the two first rail sections 200. This case is described as phase b). In this case, the mounting device 100 reaches the uppermost position on the two first guide rail sections 200. As explained above, the mounting device 100 can only be moved up along the rail section 200 by actuating the winch 430 without particularly actuating the safety device 140 (i.e. by pulling the balancing device 170).
When the mounting device 100 reaches the position shown in phase b) and all necessary work has been completed along the two first guide rail sections 200, two further guide rail sections are mounted on the two first guide rail sections 200 previously mounted. Obviously, the two further guide rail sections 200 are each vertically aligned with the previously installed first guide rail section 200. These guide rail sections 200 potentially constitute the entire guide rail together with further vertically aligned guide rail sections not shown in the figures.
Stage c) shows the situation where the further guide rail section has been vertically aligned with the first guide rail section and is mounted to the hoistway wall again using the bracket 410.
The bracket 470 can now be moved upwards along the first guide rail section 200 and the further guide rail section 200 mounted in alignment therewith to reach the new position shown in stage d). During this displacement of the bracket 470, the mounting device 100 is fixed in its position (uppermost position on the first rail section 200) by the safety device 140 and the winch mechanism 430 is deactivated, so that no pivoting force acts on the bracket 470.
Again, once the winch mechanism is actuated to further lift the mounting device 100 along the further rail section 200, this pivoting force acts again on the bracket 470, so that it becomes temporarily unable to move in the downward direction again.
Then, as described in relation to stages a) and b), the upward movement of the mounting device 100 may be continued until the mounting device 100 reaches the uppermost position on the further rail section 200. In the embodiment shown in fig. 4, this uppermost position corresponds to the uppermost position in the elevator shaft as can be seen in stage e). Obviously, in case the elevator hoistway is long, additional guide rail sections may be provided to extend the guide rail further vertically.
The mounting device can be moved along the rail section 200 in a downward direction by pulling or actuating the counterbalance device 170 and simultaneously releasing the cable 440 of the winch 430.
As an alternative to the carriage movable along the guide rail as shown in fig. 5, it is also possible to use a carriage as shown in fig. 6, which also engages the guide rail section and can be moved along it. The bracket is designated by reference numeral 480. In the same way as described in relation to the working platform with reference to fig. 3, the bracket 480 is provided with two safety devices 490. Each safety device 490 includes a U-shaped profile that is adapted and arranged to interact with a T-shaped rail section 200 of an elevator system. The U-shaped profile includes a central channel that tapers in an upward direction as described above with respect to the safety 140 of the work platform 110. The function of the safety device thus corresponds to the function already described above in relation to the safety device 140.
The bracket 480 also includes an opening 480d that is adapted to be engaged by the winch mechanism 430.
Alternatively, instead of using a movable bracket 470 or 480, a winch mechanism may be adapted to engage the mounting bracket 410. In this case, when the mounting device 100 reaches the uppermost position relative to the guide rail section 200, it is necessary to disengage the winch from the initial mounting bracket 410 to which it is attached and engage it with a further mounting bracket 410 arranged vertically above the previous mounting bracket.
