In the preferred embodiment of the present invention, the power adapter 2 is connected to each lifting device 1 via at least one dc power line 3.
In the preferred embodiment of the present invention, the dc power line 3 includes a power input terminal 31 and at least two power output terminals 32.
Preferably, the power adapter 2 is provided with a male plug, the dc power line 3 is a two-core 1-to-2 cable, the power input terminal 31 of the dc power line 3 is a female plug correspondingly connected to the male plug of the power adapter 2, the power output terminal 32 of the dc power line 3 is a male plug, the input terminal of the elevating member 11 is a female plug correspondingly connected to the male plug of the power output terminal 32. When two lifting devices 1 are arranged, only the dc power supply line 3 is required.
In a preferred embodiment of the present invention, if the number of the lifting devices 1 is greater than the number of the power output terminals 32 of one dc power line 3, a plurality of dc power lines 3 are provided, and the dc power lines 3 are connected in series in sequence.
Specifically, in this embodiment, similarly taking the dc power line 3 as a two-core line of 1 to 2 as an example, if there are three lifting devices 1, two dc power lines 3 are required, the power input end 31 of the first dc power line 3 is connected to the power adapter 2, one power output end 32 of the first dc power line 3 is connected to one lifting device 1, the other power output end 32 is connected to the power input end 31 of the second dc power line 3, and the two power output ends 32 of the second dc power line 3 are respectively connected to one lifting device 1, so that when the number of the lifting devices 1 increases gradually, flexible expansion can be performed by adopting a mode of sequentially connecting more dc power lines 3 in series.

In the preferred embodiment of the present invention, in each lifting device 1, each lifting component 11 includes a lifting controller 12 and at least one lifting actuator 13, and a control chip 121 and a voltage detection circuit 122 connected to the control chip 121 are configured in the lifting controller 12;
the control chip 121 receives the real-time voltage value detected by the voltage detection circuit 122, and adaptively adjusts the lifting speed of each connected lifting actuator 13 through the serial connection line when the real-time voltage value is greater than a voltage threshold value, so as to perform overload protection on the power adapter 2.
Specifically, in this embodiment, the control chip 121 may further include a memory, where a plurality of preset lifting speeds are stored in the memory, and three lifting speeds are taken as an example, that is, the three lifting speeds include a first speed, a second speed and a third speed, where the first speed is greater than the second speed, and the second speed is greater than the third speed, so as to immediately divide the lifting speed of the lifting executing structure 13 into three gears. Under normal conditions, during lifting, the first speed is adopted by default, when the real-time voltage value is greater than the voltage threshold value, it is described that a plurality of lifting devices 1 perform lifting operation at the same time, in order to avoid overload of the power adapter 2, at this time, the control chip 121 firstly adjusts the first speed to the second speed, at this time, if the real-time voltage value is not greater than the voltage threshold value, the second speed is kept for lifting, if the real-time voltage value is still greater than the voltage threshold value, the second speed is adjusted to the third speed, at this time, if the real-time voltage value is not greater than the voltage threshold value, the third speed is kept for lifting, if the real-time voltage value is still greater than the voltage threshold value, since the lifting speed is already reduced to the minimum value, at this time, the control chip 121 controls the lifting execution mechanism 13 to stop running. More preferably, the control chip 121 controls the lifting actuator 13 to stop operating, and may further generate an overload prompt for the user to check.

Specifically, in the present embodiment, the power adapter 2 has a rated voltage, but in actual use, the no-load voltage value and the rated voltage generally have a certain difference, and when configuring the voltage threshold value in the overload protection, the no-load voltage value is required to be used as a reference. Considering that the power adapter 2 may need to be replaced due to the increase of the number of the lifting devices 1 or other situations that the power adapter 2 needs to be replaced, after the power adapter 2 is replaced, the overload protection cannot be realized by using the historical voltage threshold, by setting the configuration button 123, when all the lifting devices 1 are idle at each time of powering on the power adapter 2, the configuration button 123 is pressed to record the idle voltage value at that time, preferably, the difference between the voltage threshold and the idle voltage value can be configured in the memory, and after the idle voltage value is recorded, the voltage threshold is automatically updated according to the difference.
The application still provides a lift table system, adopts foretell novel power supply system to supply power, and wherein, elevating gear is the lift table, and each lift part is including the controller and the support post of lift table.
While the utility model has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model.
