Hereinafter, the operation process and control method of the platform system for elevator installation of the present utility model will be described with reference to fig. 2 to 8.

As shown in fig. 2 to 8, the bottom deck 1 and the top deck 2 are respectively raised by one floor height in the vertical direction by the driving elements of the deck system. However, it will be understood by those skilled in the art that the elevation height of each operation of the platform system of the present utility model is not limited thereto, and the platform system may perform not only an elevation operation but also a descent operation.

With reference to fig. 2, the bottom platform is at the landing N, the top platform is at the landing n+1, N is a natural number, and preferably, before the platform system performs the lifting operation, the control unit compares the current first state information, the second state information, the third state information, the fourth state information, the fifth state information and the sixth state information with predetermined state parameters to obtain a comparison result, so that whether each component in the platform system is at an appropriate position or state at this time can be determined, so as to avoid affecting subsequent related operations. A lifting operation of the platform system can be largely divided into the following steps:

The optical sensor monitors whether an obstacle exists above the top platform, and when the comparison result of the third state information and the predetermined state parameter meets the preset condition, that is, the obstacle does not exist above the top platform, the control unit controls the second driving unit to retract the third support and the fourth support, as shown in fig. 3;

S2, the control unit controls the jacking component to enable the top platform to start to move upwards, at the moment, whether the top platform is moved to a proper position (such as the height of the landing N+2) can be judged based on the comparison result of the second state information and the preset state parameter, when the comparison result of the second state information and the preset state parameter meets the preset condition, namely, the top platform is moved to the proper position, the extension operation of the jacking component is completed, and accordingly, the control unit controls the jacking component to stop continuously executing the extension operation, as shown in fig. 4;

S3, the control unit controls the second driving unit to extend out of the third supporting member and the fourth supporting member, as shown in FIG. 5;

The control unit needs to determine whether the subsequent operation can be continued based on the comparison result of the fourth state information, the fifth state information and the sixth state information with the predetermined state parameter, wherein when the comparison result of the fourth state information, the fifth state information and the sixth state information with the predetermined state parameter satisfies the preset condition, that is, the inclination angle of the top platform meets the relevant requirement, the third support and the fourth support have been stably supported on the floor surface and the hoistway wall hole and the target object carried by the bottom platform is not overweight, the control unit controls the first driving unit to retract the first support and the second support, as shown in fig. 6;

S5, the control unit controls the lifting assembly to enable the bottom platform to start to move upwards, at the moment, whether the bottom platform is moved to a proper position (such as the height of the landing N+1) can be judged based on the comparison result of the first state information and the preset state parameter, when the comparison result of the first state information and the preset state parameter meets the preset condition, namely, the bottom platform is moved to the proper position, the lifting operation of the lifting assembly is completed, accordingly, the control unit controls the lifting assembly to stop continuously executing the lifting operation, and in addition, the control unit controls the lifting assembly to execute the retraction operation while controlling the lifting assembly to execute the lifting operation, as shown in fig. 7;

S6, the control unit controls the first driving unit to extend the first support and the second support as shown in FIG. 8, and

The control unit needs to determine whether the platform system has completed one ascent operation based on the comparison result of the fourth and fifth state information with the predetermined state parameter, in which case it can be determined that the platform system has completed one ascent operation when the comparison result of the fourth and fifth state information with the predetermined state parameter satisfies the preset condition, i.e., the inclination angle of the bottom platform meets the relevant requirement and the first and second supports have been stably supported on the floor surface and the hoistway wall hole.

In step S4, when the comparison result of the fourth state information and the predetermined state parameter does not meet the preset condition but meets the adjustment condition, that is, the inclination angle of the top platform does not meet the related requirement but is within the adjustable range, in this case, the control unit may adjust the inclination angle of the top platform by controlling the second adjustment unit until the inclination angle of the top platform meets the related requirement.

In step S7, when the comparison result of the fourth state information and the predetermined state parameter does not meet the preset condition but meets the adjustment condition, that is, the inclination angle of the bottom platform does not meet the related requirement but is within the adjustable range, the control unit may adjust the inclination angle of the bottom platform by controlling the first adjustment unit until the inclination angle of the bottom platform meets the related requirement.

In the whole operation of the platform system, once the comparison result of the first state information, the second state information, the third state information, the fourth state information, the fifth state information and the sixth state information with the preset state parameters is abnormal, the control unit immediately controls the platform system to stop running, so that the operation risk can be reduced.

Further, according to another embodiment of the present utility model, the first and second supports may be further provided with sensors configured to monitor the lengths of the first and second supports protruding from the bottom platform, whereby it is possible to determine whether the operations of the first and second supports in steps S4 and S6 have been properly performed based on the state information obtained by the sensors. Similarly, the third and fourth supports may also be provided with sensors configured to monitor the lengths of the third and fourth supports protruding from the top platform, whereby it may be determined whether the operations of the third and fourth supports have been properly performed.

Furthermore, according to still another embodiment of the present utility model, the landing system for elevator installation may further include an optical auxiliary installation module and an unmanned aerial vehicle module, wherein the optical auxiliary installation module may be used for installation positioning of elevator components, the unmanned aerial vehicle module may collect spatial information of an elevator hoistway for installation of an elevator and transmit the collected spatial information to the control unit, and then the control unit simulates a hoistway layout of elevator installation based on the received spatial information and determines whether the current elevator hoistway meets elevator installation requirements.
