Description

The invention relates to a method for operating a construction hoist. The construction hoist essentially consists of a vertical mast and a platform movable along the mast by an engine to the individual floors.

Such a lift with a, movable on a mast platform is the DE 100 58 021 C2 refer to. Such an elevator has a control device which can be actuated by the platform as a transport platform with a low driving speed and by an outside control station arranged outside the platform as a construction hoist with a higher driving speed. Both on the platform, as well as on the outside steering position, arranged control device is designed so that it can optionally connect to the control device of the platform or the control device of the outside control station a control panel. Here, a switching device is arranged on the outside control station, which is connected to the operating mode as a construction hoist with the control panel connected and the operation as a transport platform when the control panel is removed.

Such construction hoists are well known in various embodiments. They serve to transport either people or loads in different floors of a building, depending on the load different requirements are placed on the design of the elevator car or platform. Thus, passenger elevators, which are also suitable for transporting material, are commonly used with a closed elevator car with door and roof, in order to ensure that the persons in the elevator car can not fall out of the car while driving and also objects falling from a scaffold or the like can be taken.

In the DE 10 2005 039 531 A1 discloses a method for wireless commissioning and operation of a lift or crane, in particular a stairlift. The travel movement of this elevator is effected by an electric motor, which is connected to a control and regulating circuit and is supplied by the latter with the electrical energy, at the touch of a button, the device providing a remote control with a power supply equipped with functional elements for actuating switching elements is. Upon actuation of one of these functional elements directly or indirectly at least one other switching element is switched simultaneously and in the remote control commands are generated as a low-frequency signal and transmitted to the control and regulating circuit.

In the DE 10 2008 018 710 A1 an elevator installation with at least one elevator car, which is destination-controlled by a control device in a first operating state, is shown. This elevator installation has input means in the floors in the form of touch screens in order to initiate a special drive for the control.

With the DE 27 33 441 A1 has become known elevator control, in which the wiring for the control between each floor and the cabin has dropped. A wireless device in the form of energy radiation is used to transmit the control signals. In the manhole frames, transceivers are arranged to request.

A device for the vertical transport of persons and / or materials is used in the DE 201 04 491 U1 disclosed. The drive is connected to external actuators located outside the platform and actuators located within the platform.

The object of the invention is that the requirement of the platform to one of the floors above or below are more effectively and easily solved than the verbal signings used today, or an elaborate wiring of the individual floors with each other. Furthermore, the transport performance of such construction lifts should be increased.

The object of the invention is solved by the features of claim 1.

The invention proposes the solution that any floor is a separate floor transmitter that is wirelessly, preferably held in a wall bracket is used. Such a floor transmitter serves to cause the request of the platform of the building hoist by operating one of the keys either "up" or "down". By pressing one of the keys "up" or "down", to which the corresponding person wants to drive himself or wants to create material, is transmitted via radio to a radio receiver. This radio receiver is stationary within the platform, preferably housed within the controller and receives this request signal from the corresponding floor. The elevator operator, who carries out the operation of the elevator within the elevator car or the platform, can see on a display panel from which floor the request has been triggered. At the same time, by sending the radio signal, the information has also been transmitted in which direction, "up" or "down" the requesting person wishes to travel. The display panel displays the corresponding requesting floor and the desired direction of travel. That's it Display panel designed according to a first preferred embodiment so that for each floor at least a separate display is available. Such a display may be a signal light or, preferably, an LED display.

In a preferred embodiment, a separate series of displays for each floor is provided for each direction of travel.

The level transmitters described above are equipped so that they can be programmed according to the number of floors used. This ensures that, after the creation of a new further floor, a further additional floor transmitter, preferably in the area of the building hoist, is determined.

In a preferred embodiment it is possible for the floor transmitter to have only one button for requesting the building hoist. In such a case, the Bauaufzugsführer gets only the requested floor for display.

In a further preferred embodiment, the operating device present in the cabin or platform essentially consists of a programmable microprocessor control, which is connected to an operating unit. With the control of the radio receiver and the at least one display panel are connected accordingly. In a further preferred embodiment, optionally, a numeric keyboard may be present, which allows the operator to enter the desired floor, whereupon the building elevator either automatically moves to this floor or as it is usually carried out in this area by the operation of a so-called deadman button.

Since such hoists are used for structures of different heights, it is possible to equip the display panel exchangeable or retrofittable.

• – Betätigung eines Etagensenders durch eine Person zur Anforderung des Bauaufzuges,
• – Übermittlung der Anforderung per Funk an den Funkempfänger in der Plattform,
• – Anzeige der gewünschten Fahrtrichtung und der auslösenden Etage auf dem Anzeigentableau,
• – Betätigung der geforderten Totmanntaste oder Eingabe der gewünschten Etage mittels der nummerischen Tastatur durch den Aufzugführer,
• – Bauaufzug fährt zu der angeforderten Etage.

To use such a device described above, consisting of a corresponding number of floor transmitters and a radio receiver in the platform, the sequence of the method for operating such a building hoist can be carried out according to the following steps:

• Operation of a floor transmitter by a person to request the building hoist,
• Transmission of the request by radio to the radio receiver in the platform,
• Display of the desired direction of travel and the triggering floor on the display panel,
• Actuation of the required deadman key or entry of the desired floor by means of the numeric keypad by the elevator operator,
• - Construction hoist drives to the requested floor.

By such a method, the transport performance can be increased enormously, because, for example, in the request of several floors on a guideway they can be executed simultaneously. This saves appropriate working time and thus occurs a reduction in construction costs. Also, the reliability is greatly increased because the use of floor transmitters in conjunction with a radio receiver on the one hand, the laying of expensive cables is avoided to each floor and at the same time the risk of damage to such cables is completely eliminated. Damage to the cabling used so far means standstill of the construction hoist. Such failures of the construction hoist are avoided by the invention.

The invention will be explained in more detail with reference to a possible performance example shown schematically in the drawings.

It shows:

1 : A schematic representation of a building elevator in connection with a multi-storey building;

2 a first preferred embodiment of an operating device located in the platform;

3 A second preferred embodiment such as 2 but with additional numeric keypad;

4 A further preferred embodiment of a display tableau.

According to the 1 The construction elevator consists essentially of a vertically oriented mast 1 , on which a platform can be moved 2 located. In the platform 2 is an operating device 3 which will be referred to later. In order to be able to use the building hoist operationally, there is a control cabinet on the ground floor 4 to which a stationary operating unit 5 is appropriate. The stationary control unit is used to operate the construction hoist from the ground.

In the individual floors 11 . 12 . 13 . 14 . 15 , in which 15 For n stands, are each floor transmitters 6 . 7 . 8th . 9 . 10 , in which 10 For n stands, exists. These floor transmitters 6 . 7 . 8th . 9 . 10 are preferably mounted in a wall mount near the construction hoist. According to the number of floors are the single floor transmitter 6 . 7 . 8th . 9 . 10 programmed so that when delivering a radio signal via the integrated antenna a definitive statement on a display panel 23 within the operating device 3 is performed.

A first preferred embodiment of the operating device 3 can he 2 be removed. It is within the operating device 3 an operating unit 17 present, preferably for guiding the platform 2 serves. The operating unit 17 basically has an emergency stop button 18 , an upward deadman button 19 , a down-deadman button 21 and a stop button 20 on. To the control unit 17 can also make a key switch ready to use 22 available. With the control unit 17 , whose other functional elements are not relevant to the invention and therefore are not shown, operates a microprocessor control 28 together, via a connection with a radio receiver 16 and its antenna in conjunction with the floor transmitters 6 . 7 . 8th . 9 . 10 stands. To the microprocessor control 28 is in the representation of 2 on the right side an advertisement tableau 23 There are a number of floor displays on the left side 24 is present for a number of floors and next to this ad 24 is a request direction indicator 25 available. Now by one of the floor transmitters 6 . 7 . 8th . 9 or 10 a request for one of the ads shown here 1 to n performed, a corresponding signal light or LED display is lit and at the same time when requesting the upward movement is the request direction indicator 25 displayed. On the right side, the same display version is available again, so here too for the floors 1 to n corresponding floor displays 24 available. Also located next to the floor indicator 24 a request direction indicator 26 but indicating the down request.

Now by one of the floor transmitters 6 to 10 If a selective request for a floor to be approached is executed, this is displayed on the display panel 23 Visible and at the same time becomes the desired direction of travel 25 or 26 displayed. The building elevator operator located in the platform can thus directly recognize where he has to go and by pressing either the deadman button 19 or 21 he can thus approach the desired floor. As a result, enormous time losses are compensated, so that it also comes at the same time to a transport performance increase.

According to the 3 is in a further preferred embodiment in addition to the execution of 2 in addition a numeric keyboard 27 existing, which serves that the construction elevator operator deletes the landed floor request by a corresponding acknowledgment. However, it is also possible that via the operating device 3 by means of the microprocessor control 28 an automatic deletion of the approached floor on the display panel 23 is carried out.

The 4 shows in a further preferred embodiment, a modification of the display panel 23 , which in this case only a number of floor displays 24 having. With such a simplified design, the construction elevator operator can not recognize in which floor the requested drive should go.

The floor transmitter described so far 6 to n was equipped with two buttons, whereby in addition to the requesting floor and the desired direction of travel was transmitted by radio. In a further preferred but simplified embodiment, the floor transmitter 6 to n also have only one key. Through this button is only the request of the platform by radio 2 causes, in which case only a display panel 23 according to the execution of 4 Use finds.

The present method contributes to increasing the transport performance of construction hoists. While earlier cables had to be laid consuming to each floor and these were damaged, for example, by falling objects, which in principle meant that such a construction hoist for a non-predictable period was unusable, today is in addition to a reduction in installation time and cost savings for the Cabling also a failure of the construction hoist because of damaged cables are no longer given.
