The working principle and the process of the invention are as follows:
the corridor elevators have different load rating requirements in different use scenarios, such as: the load ratings vary from motor to motor and from user to user. According to the invention, according to actual requirements, when the preliminary calibration of the corridor elevator carrying device is carried out, the microswitch group 6-5 is positioned at the highest position of the spring leaf 6-4, the weight of a target rated load is placed on the movable plate 6-1 of the upper pedal 5-7, the movable plate 6-1 moves downwards, the spring leaf 6-4 in contact with the movable plate 6-1 is pressed downwards, the foldable wrench handle 6-6-4 is rotated, the movement form of the screw and nut mechanism 6-6 is adjusted to be converted, so that the microswitch group 6-5 moves, until the microswitch group 6-5 is pressed down by the spring leaf 6-4, a switching signal is transmitted to the control system, and the calibration is judged to be finished at the moment.
Because of the deformation of the parts, the corridor elevator needs to be periodically maintained at a later stage, and the rated load can be set by adjusting the micro switch group 6-5 directly by a method of early calibration.
When the carrier device is not in operation, it is in the condition of fig. 7. When a user presses a button of the corridor elevator, the corridor elevator can move towards the position of the user, when the corridor elevator arrives, the servo motor 5-1 rotates forwards to drive the nut block 5-14 and the upper pedal 5-7 to move downwards, the lower pedal 5-9 also moves downwards around the third connecting shaft 5-19, and finally the corridor elevator and the lower pedal are stacked and in a horizontal state, as shown in figure 5, and the nut block 5-14 and the upper pedal 5-7 move downwards.
After the upper pedal 5-7 and the lower pedal 5-9 are both laid flat, the user stands at the position of a moving plate 6-1 of the upper pedal 5-7, the rated load adjustable mechanism 6 can compare the weight of the user with the rated load, and if the user is overloaded, the user cannot start the system; if the overload is not generated, the carrying device is driven to move forward by the external drive after the user station stably presses the start key.
When the pedal is removed after use, the servo motor 5-1 rotates reversely to drive the nut block 5-14 and the upper pedal 5-7 to move upwards, the lower pedal 5-9 also moves upwards around the third connecting shaft 5-19, and finally, the lower pedal and the upper pedal are level and vertical, so that the space is saved, and the pedal is referred to fig. 7. This completes a working cycle of the loading device.
The implementation shows that the device can meet the requirements that the corridor elevator has different rated loads in different use scenes, and meanwhile, the convenience of early calibration and later maintenance of the corridor elevator carrying device is improved. The double-pedal retraction mechanism not only can be folded, but also can be used for judging whether the upper pedal is overloaded or not, the lower pedal is mainly used for bearing, the division of labor is clear, the deformation of the weighing device in the upper pedal can be reduced, and the service life of the loading device is prolonged.
