Description

Emergency power device, elevator system, method for emergency operation of an elevator system The invention relates to an emergency power device, an elevator system and a method for emergency operation of an elevator system according to the preamble of the independent claims. In the event of a power failure, it must be possible to free trapped passengers. In this case, the elevator system is powered by an emergency power supply. An emergency power supply with a separate emergency power module can be provided for this purpose. In the case of an elevator system, it must be possible for specialist personnel to operate the elevator system at least partially from an emergency power supply in emergency operation, i.e. for example in emergencies, during commissioning, acceptance or testing, as well as during maintenance and in other operating modes that deviate from normal operation. In particular, the elevator system must be provided with energy from an emergency power supply that is sufficient to open the brake and, if necessary, operate the drive and to enable other functions necessary for the evacuation of passengers. A device is known from the utility model DE 296 15 921 UI by means of which elevator passengers can be evacuated in an emergency. The device is intended for elevator systems without a machine room, in which the drive unit is located in the shaft. If the elevator car gets stuck in the elevator shaft, the brake is released manually and the elevator car is driven to the next floor. The brake is operated by means of a Bowden cable from the floor. During the evacuation, the elevator car moves when the elevator system is de-energized. Only a battery is provided to power a signaling device which indicates that the elevator car is on the evacuation floor. A disadvantage of the known elevator system and the previously described method for emergency operation of this elevator system is that during emergency operation only the brake of the elevator system can be operated. Other functions available during normal operation of the elevator system, such as opening an electronic door lock or operating a door drive, are not possible with the emergency operation device known in the prior art. The task is to further develop the state of the art with regard to the emergency operation of an elevator system. In particular, an emergency power device that is simple and easy to transport and handle is to be provided. Existing disadvantages and restrictions with regard to emergency operation are advantageously reduced or at least reduced. The object is achieved in various aspects with an emergency power device according to the claims, an elevator system according to the claims and a method according to the claims. Particular embodiments are the subject of the dependent claims. Advantageous embodiments also emerge from the description and the drawings. According to the claim, the emergency power device for an elevator system comprises an energy storage device and an energy storage holding device. The energy storage holding device can be connected to the energy storage device in a force-fitting and/or form-fitting manner or is connected in an assembled state. The emergency power device is portable, in particular portable by a person. The energy storage device and the energy storage holding device preferably form a compact and rigid arrangement via their connection. In one embodiment of the emergency power device described above and below, the connection between the energy storage holding device and energy storage devices are designed to be removable without causing any damage. This makes it possible to use one and the same energy storage holding device with several energy storage devices and/or vice versa. The fact that the emergency power device is portable, in particular by one person, means that it can be lifted and preferably transported by one person, for example a service technician, using muscle power. In particular, the emergency power device can be designed to be lifted with one hand. It is advantageous that the emergency power device can be moved or transported from one elevator system to another. The emergency power device can be taken from one elevator system to the next by maintenance personnel and can be easily carried from a car to the elevator system, for example. This makes it possible in particular to design the emergency power device for the elevator system, or the elevator system itself, more cost-effectively, since there is no longer any need for a separate energy storage device for emergency operation that is permanently connected to the elevator system. In one embodiment of the emergency power device described above and below, the emergency power device is designed to supply electricity to at least one drive of the elevator system. In a special embodiment, the emergency power device is designed to supply electricity to two drives of the elevator system at the same time. This is particularly advantag
