Definitions

  • the embodiments herein relate to lifting technologies for lifting objects.
  • the embodiments herein relate to a lifting device for lifting an object connected to a suspendable casing of the lifting device.
  • Lifting technologies for lifting of objects are used in many different environments, such as transporting environments, health care environments, manufacturing environments and the like. In many environments, it may be suitable to use a known lifting arrangement that is suspendable in a beam or the like and which is easy to operate by means of a handle at a lower portion of the lifting arrangement.
  • a disadvantage with the known lifting arrangement may be that it is time consuming and costly to install the lifting arrangement at a site, i.e. where objects are desired to be lifted.
  • the know type of lifting arrangement has the following general composition.
  • the lifting arrangement comprises a suspendable lifting unit, which is connected to an electrical power supply for serving the lifting arrangement with enough power to lift relatively heavy objects.
  • the need for the electrical an electrical power supply makes installation of the lifting arrangement dependent on access to an electrical power supply.
  • Some known lifting arrangements are connected to a pneumatic supply for delivering power to lift objects. As a result, the locations at which the known lifting arrangement may be installed are severely limited, i.e. the lifting arrangement may only be installed where there is an available an electrical power supply or a pneumatic supply.
  • document DE 20 2018 103817 U1 discloses a lifting device according to preamble of claim 1.
  • the present inventors have realized that there is a need for a lifting arrangement that is easy to move from one location to another, i.e. a lifting arrangement that is more flexible in terms of mobility and simplicity of installation.
  • An object may thus be how to provide a more flexible and mobile lifting device which overcomes, or at least alleviates, the abovementioned disadvantage.
  • a lifting device for lifting an object.
  • the lifting device comprises a casing arranged to be displaced when the lifting device is operated to lift the object, a string mounted within the casing and extending out of the casing, and a maneuverer member, such as a handle.
  • the maneuverer member is connected to the casing and arranged to provide sensing signalling representative of a direction of the movement of the casing when the lifting device is operated.
  • the casing is suspendable by means of the string and the lifting device is arranged to adjust a length of the string extending out of the casing to achieve a movement of the casing.
  • the casing comprises a control unit arranged to control, based on the sensing signalling, the length of the string extending out of the casing, and an electric motor arranged to be controlled by the control unit to cause the movement of the casing.
  • the lifting device is arranged to adjust the length of the string extending out of the casing by that the electric motor is arranged to wind-up or un-wind the string.
  • the lifting device comprises a battery arranged to power the electric motor.
  • the battery is further arranged to accompany the casing when displaced.
  • the casing has an opening.
  • the casing is arranged to hold the battery to obscure the opening when the battery is releasably mounted in the casing. Thanks to the opening, an easy way of accessing the string may be provided.
  • the opening may be used for untangling the string in case of lifting failure due to tangled string.
  • the lifting device is simple to install, e.g. due that no external power source needed, no wiring to an electric outlet is required or the like.
  • Another effect of that the battery is arranged to power the electric motor and to accompany the casing when displaced is though that weight of the casing is increased.
  • the present inventors have thus realized that advantages like simple installation and high mobility overturns a possible disadvantage of increased weight which may decrease lifting capacity, i.e. a maximum weight of an object that the lifting device is capable of lifting.
  • the battery is arranged to power the control unit.
  • the battery is used for powering both the electric motor and the control unit.
  • An advantage may be that material cost of the lifting device may be less than if separate batteries are used.
  • the lifting device is provided with a further battery, i.e. separate and different from the aforementioned battery.
  • the further battery is arranged to power the control unit. In this manner, the control unit is be able to indicate that the battery for powering of the electric motor may need to be re-charged, even when that battery is completely empty, or at least discharged to an extent that the control unit is not operational.
  • the casing at least partly encloses the battery.
  • the battery is integrated into the lifting device. Hence, the battery is protected by the casing that also encloses amongst other the control unit and the electric motor.
  • the battery is releasably mounted at the casing. This means that the battery is removable from the lifting device. In this manner, the battery may easily be replaced when discharged. Hence, if the battery is discharged, it may be replaced with another fully charged battery. Hence, continued operation of the lifting device may be achieved after only a short down time for the exchange of the discharged battery.
  • the maneuverer member is detachably connectable to the object.
  • an operator of the lifting device may intuitively lift the object by use of the lifting device as if the operator would lift the object in real-life, with a gripping device, i.e. without lifting assistance from the lifting device.
  • the maneuverer member is connected to an interior of the casing using at least a lever arm rotatably connected to the interior of the casing.
  • the lever arm is provided with a first position sensor, wherein a second position sensor is fixedly attached to the interior of the casing.
  • the control unit is arranged to control the electric motor based on the sensing signalling represented by a difference between a first sensing signal from the first position sensor and a second sensing signal from the second position sensor.
  • the first and second sensing signals are caused by that the maneuverer member is operated to displace the casing.
  • the difference between the first and second sensing signals may indicate a desired direction for the movement of the casing
  • the lever arm may be part of a joint for transferring the operator's control movements that are intended to inform the lifting device about the operator's intention, i.e. lifting, lowering or keeping steady.
  • the lever arm and the first and second sensors may consequently transfer the control movements to the sensor unit connected to the control unit by means of the sensing signalling.
  • the control movements may indicate a direction of movement that the operator desires to move the object, e.g. heighten or lower a position of the object.
  • lifting may include heightening or lowering the position of the object.
  • the casing comprises a winding cylinder arranged to wind the string onto the winding cylinder to adjust the length of the string extending out of the casing. in this manner, the winding cylinder achieves the movement of the casing.
  • the casing comprises a detection element arranged to detect load or no load on the string by being arranged to perform a movement due to that the string abuts the detection element during load and by being arranged to drive the movement during load and by being arranged refrain from performing the movement due to that the string relaxes and fails to drive the movement during no load.
  • control unit is arranged to receive a load signal indicative of load or no load.
  • the control unit may be arranged to prevent the movement for lifting the object. The movement may e.g. be prevented by that the control unit terminates powering of the electric motor, or at least controls the electric motor to stop winding the string.
  • the detection element comprises a detection cylinder and the movement is a rotational movement. Rotation or non-rotation of the detection cylinder is then an indication of load or no load, respectively.
  • the detection element comprises a detection lever arm that is spring biased towards a first position.
  • the detection lever arm is arranged to assume the first position during no load and wherein the detection lever arm is arranged to assume a second position against bias of the detection lever arm during load.
  • the movement is a translational movement.
  • the detection element is either the detection cylinder or the detection lever arm.
  • the detection element may be realized by comprising a detection cylinder that is supported by a detection lever arm. Accordingly, it is contemplated that a combination of the detection cylinder and the detection lever arm may be realized without undue burden.
  • the lifting device has a lifting capacity 300 N or less.
  • the lifting capacity is dependent on the power of the electric motor.
  • the power of the electric motor sets requirements on the battery to drive it.
  • a more powerful battery is able to power an electric motor with a greater lifting capacity than a less powerful battery.
  • increased power also comes with increased weight. Therefore, in order to achieve desired mobility and flexibility with known batteries, it is expected that the lifting device has a lifting capacity of 300 N or less.
  • a lifting capacity of 300 N normally corresponds to that the lifting device is able to lift an object having a mass of 30 kg.
  • some batteries may be able to achieve a lifting capacity above 300 N.
