The vertical direction is the height direction of the elevator shaft. Usually, the position of each of the plurality of shaft wall holes in the vertical direction substantially corresponds to the position of the floor in the vertical direction of the matching floor, and here, "corresponding" means that the heights of the shaft wall holes and the floor that match each other are the same or the height difference between the shaft wall holes and the floor that match each other is within a specified range.

[0045] According to an exemplary embodiment of the utility model, a platform system for elevator installation may include a bottom platform 1, a top platform 2, a climbing mechanism, a sensor assembly and a control unit, wherein the top platform 2 is located above the bottom platform 1, and the top platform 2 and the bottom platform 1 are spaced apart from each other in the vertical direction; the climbing mechanism is arranged between the bottom platform 1 and the top platform 2 and is configured to adjust the heights of the bottom platform 1 and the top platform 2 in the vertical direction; the sensor assembly is configured to monitor the state of the platform system to obtain state information; the control unit is electrically connected to the bottom platform 1, the top platform 2, the climbing mechanism and the sensor assembly and is configured to receive the state information obtained by the sensor assembly, and the control unit compares the received state information with a predetermined state parameter and controls the platform system based on the comparison result to perform corresponding operations.

[0046] More specifically, the control unit is electrically connected to the components disposed on the bottom platform 1 and the top platform 2 .

[0047] Further, the climbing mechanism of the exemplary embodiment of the utility model may include: a jacking assembly 3 and a lifting assembly 4, wherein the jacking assembly 3 is installed on the top of the bottom platform 1, the jacking assembly 3 is a one-way drive telescopic assembly, and the top platform 2 moves in the vertical direction based on the extension operation of the jacking assembly 3 (with reference to Figure 4 ); the lifting assembly 4 is installed at the bottom of the top platform 2. When the extension operation of the lifting assembly 3 is completed, the lifting assembly 4 performs a pulling operation to move the bottom platform 1 in the vertical direction, and the lifting assembly 3 performs a retraction operation (with reference to Figure 6 and Figure 7 ). The lifting assembly 3 and the pulling assembly 4 are electrically connected to the control unit, so that the extension operation and retraction operation of the lifting assembly 3 and the pulling operation of the pulling assembly 4 are controlled by the control unit.

[0048] In detail, when the control unit controls the jacking assembly 3 to perform an upward extending operation, the jacking assembly 3 pushes against the top platform 2 to move the top platform 2 upward; when the control unit controls the pulling assembly 4 to perform a pulling operation, the pulling assembly 4 pulls the bottom platform 1 to move the bottom platform 1 upward, and the jacking assembly 3 performs a retracting operation; thus, the jacking assembly 3 cooperates with the pulling assembly 4 to make the top platform 2 and the bottom platform 1 move in the vertical direction.

[0049] In the example shown, the lifting assembly 3 is a hydraulic drive assembly, and the lifting assembly 4 is an electric hoist. However, those skilled in the art should understand that the structures of the lifting assembly 3 and the lifting assembly 4 should not be limited to this, and any other structures that can achieve the same technical effect can be used, for example, the lifting assembly 3 can also be a worm gear assembly, a gear / rack transmission assembly or a screw assembly, etc., and the lifting assembly 4 can also be a hand chain hoist, etc. Any other equivalent solutions that can be thought of by those skilled in the art are included in the concept of the utility model, and will not be repeated here one by one.

[0050] In addition, although the number of lifting components 3 and pulling components 4 is set to one respectively in the example shown, according to the actual application situation, the number of lifting components 3 and pulling components 4 can also be set to multiple respectively, and the number of lifting components 3 and pulling components 4 can be different from each other to be suitable for various application scenarios.

[0051] One end of the jacking assembly 3 may be fixedly mounted on the bottom platform 1 , and the other end of the jacking assembly 3 may be mounted to the top platform 2 via a connector (eg, a mounting bushing).

[0052] Alternatively, one end of the jacking assembly 3 may be fixedly mounted on the bottom platform 1 , and the other end of the jacking assembly 3 may also be fixedly mounted to the top platform 2 .

[0053] According to an exemplary embodiment of the present invention, the vertical movement of the top platform 2 and the bottom platform 1 is achieved by the cooperation of the jacking assembly 3 and the pulling assembly 4. However, according to another embodiment of the present invention, the vertical movement of the top platform 2 and the bottom platform 1 can be achieved by a bidirectional driving mechanism.

[0054] As an example, the climbing mechanism can be a screw sleeve structure driven by a motor, wherein the screw and the sleeve constitute a telescopic assembly, one end of which is connected to the bottom platform 1 and the other end is connected to the top platform 2. When the drive shaft of the motor rotates in the first direction, the telescopic assembly composed of the screw and the sleeve is extended, thereby pushing against the top platform 2 to move the top platform 2 upward until the top platform 2 moves to an appropriate position and then supported on the floor and the wall hole of the well; and when the drive shaft of the motor rotates in the second direction, the telescopic assembly composed of the screw and the sleeve is shortened, thereby lifting the bottom platform 1 to move the bottom platform 1 upward until the bottom platform 1 moves to an appropriate position, wherein the second direction is opposite to the first direction, for example, the first direction can be clockwise, the second direction can be counterclockwise, and vice versa. Therefore, by rotating the drive shaft of the motor in two opposite directions, the height of the bottom platform 1 and the top platform 2 in the vertical direction can be adjusted. Of course, the expression form of the bidirectional drive mechanism is not limited to this.

[0055] According to an exemplary embodiment of the utility model, the sensor assembly may include: a height sensor 5, an optical sensor 6, an inclination angle sensor 7, a pressure sensor 8 and a mass sensor 9, wherein the height sensor 5 is arranged on the bottom platform 1 and the top platform 2, and the height sensor 5 is configured to monitor the heights of the bottom platform 1 and the top platform 2 to obtain first state information related to the height of the bottom platform 1 and second state information related to the height of the top platform 2; the optical sensor 6 is arranged on the top platform 2, and the optical sensor 6 is configured to monitor whether there is an obstacle above the top platform 2 to obtain third state information related to the obstacle; the inclination angle sensor 7 is arranged on the bottom platform 1 and the top platform 2, and the inclination angle sensor 7 is configured to monitor The inclination angles of the bottom platform 1 and the top platform 2 with respect to the horizontal direction are measured to obtain fourth state information related to the inclination angles; a pressure sensor 8 is arranged on the bottom platform 1 and the top platform 2, and the pressure sensor 8 is configured to monitor whether the bottom platform 1 and the top platform 2 are stably supported to obtain fifth state information related to the supporting state; a mass sensor 9 is arranged on the bottom platform 1, and the mass sensor 9 is configured to monitor whether the target object carried by the bottom platform 1 is overweight to obtain sixth state information related to the mass; wherein the control unit compares 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 predetermined state parameters and controls the platform system based on the comparison results to perform corresponding operations.

[0056] Further, the platform system for elevator installation according to the exemplary embodiment of the present utility model may further include a first supporting assembly provided at the bottom platform 1 and a second supporting assembly provided at the top platform 2 .

[0057] In the example shown, the first support assembly disposed on the bottom platform 1 may include: a first support member 11, a second support member 12 and a first driving unit, wherein the first support member 11 may be disposed on a first side of the bottom platform 1, as shown in FIG. Figure 1 The second support member 12 may be disposed on a second side of the bottom platform 1 opposite to the first side, as shown in this Figure 1 a first drive unit (not shown) may be disposed in the bottom platform 1 and configured to extend or retract the first support member 11 and the second support member 12 relative to the bottom platform 1 .

[0058] As an example, the first driving unit may be a motor-type driving unit, and a gear rack connection structure may be provided between the first driving unit and the first support member 11 and the second support member 12. Thus, by rotating the driving shaft of the motor, the gear connected to the driving shaft of the motor cooperates with the rack parts on the first support member 11 and the second support member 12, so that the length of the first support member 11 protruding from the first side of the bottom platform 1 and the length of the second support member 12 protruding from the second side of the bottom platform 1 can be adjusted. Of course, the expression form of the first driving unit is not limited to this.

[0059] According to an embodiment of the present invention, the first support member 11 and the second support member 12 can be driven by a motor to be synchronously extended or retracted.

[0060] According to another embodiment of the present invention, the first support member 11 and the second support member 12 may be driven by two motors to extend or retract independently of each other.

[0061] Similarly, the second support assembly disposed on the top platform 2 may include: a third support member 21, a fourth support member 22 and a second driving unit, wherein the third support member 21 may be disposed on the first side of the top platform 2. Figure 1 The fourth support member 22 may be disposed on a second side of the top platform 2 opposite to the first side, as shown in this Figure 1 a second drive unit (not shown) may be disposed in the top platform 2 and configured to extend or retract the third support member 21 and the fourth support member 22 relative to the top platform 2 .

[0062] Similarly, the second drive unit may be a motor drive unit, and a gear rack connection structure may be formed between the second drive unit and the third support member 21 and the fourth support member 22. Thus, by rotating the drive shaft of the motor, the gear connected to the drive shaft of the motor cooperates with the rack parts on the third support member 21 and the fourth support member 22, so that the length of the third support member 21 protruding from the first side of the top platform 2 and the length of the fourth support member 22 protruding from the second side of the top platform 2 can be adjusted. Of course, the expression form of the second drive unit is not limited to this.

[0063] According to an embodiment of the present invention, the third support member 21 and the fourth support member 22 can be driven by one motor to be synchronously extended or retracted.

[0064] According to another embodiment of the present invention, the third support member 21 and the fourth support member 22 may be driven by two motors to extend or retract independently of each other.

[0065] Furthermore, the first driving unit of the first supporting assembly and the second driving unit of the second supporting assembly may be electrically connected to the control unit such that the first driving unit and the second driving unit are controlled by the control unit.

[0066] In the example shown, the pressure sensor 8 may be mounted on the first support 11, the second support 12, the third support 21, and the fourth support 22. By monitoring the pressure on the first support 11, the second support 12, the third support 21, and the fourth support 22, it can be determined whether the bottom platform 1 and the top platform 2 are stably supported.

[0067] Although the pressure sensor 8 is arranged on the top surfaces of the first support member 11, the second support member 12, the third support member 21 and the fourth support member 22 in the example shown, those skilled in the art should understand that the pressure sensor 8 can also be arranged inside the first support member 11, the second support member 12, the third support member 21 and the fourth support member 22, and the form of the pressure sensor 8 is not limited to this.

[0068] Furthermore, the method of judging whether the bottom platform 1 and the top platform 2 are stably supported is not limited to the pressure sensor.

[0069] According to an exemplary embodiment of the utility model, the first support assembly may further include a first adjustment unit 13, which is disposed at the bottom of the first support 11 and the second support 12 near the extended end. Similarly, the second support assembly may further include a second adjustment unit 23, which is disposed at the bottom of the third support 21 and the fourth support 22 near the extended end. In addition, the first adjustment unit 13 and the second adjustment unit 23 may be electrically connected to the control unit, so that the control unit can be operated to adjust the length of the first adjustment unit 13 and the second adjustment unit 23 in the vertical direction to adjust the tilt angle of the bottom platform 1 and the top platform 2.

[0070] Here, the extended ends of the first support member 11 and the second support member 12 are the ends of the first support member 11 and the second support member 12 away from the bottom platform 1, and the extended ends of the first support member 11 and the second support member 12 are the ends of the first support member 11 and the second support member 12 away from the bottom platform 1. Figure 1 As shown, the first adjustment unit 13 is arranged at the bottom of the first support member 11 near the left end and the bottom of the second support member 12 near the right end; the extended ends of the third support member 21 and the fourth support member 22 are the ends of the third support member 21 and the fourth support member 22 away from the top platform 2, and ... Figure 1 As shown, the second adjustment unit 23 is disposed at the bottom of the third support member 21 near the left end and at the bottom of the fourth support member 22 near the right end.

[0071] exist Figure 1 , a platform system for elevator installation is shown in the form of a cross-sectional view, wherein the bottom platform 1 and the top platform 2 have a rectangular cross-section. However, those skilled in the art can imagine that when the bottom platform 1 and the top platform 2 are viewed from a top view or a bottom view, the bottom platform 1 and the top platform 2 may have a square top surface and a square bottom surface.

[0072] According to one embodiment of the present invention, the number of the first support member 11 provided on the first side (left side) of the bottom platform 1 can be set to one, and the number of the second support member 12 provided on the second side (right side) of the bottom platform 1 can be set to one. In this case, the first support member 11 and the second support member 12 can be formed as flat plate-like members.

[0073] In addition, the first support member 11 and the second support member 12 can also be formed as flat fork-shaped members. When the first support member 11 and the second support member 12 extend relative to the bottom platform 1, the forked parts of the first support member 11 and the second support member 12 can be supported on the floor and the well wall hole respectively.

[0074] According to another embodiment of the present invention, the number of the first support members 11 disposed on the first side (left side) of the bottom platform 1 can be set to multiple, and the number of the second support members 12 disposed on the second side (right side) of the bottom platform 1 can be set to multiple. In this case, the first support member 11 and the second support member 12 can be formed as flat strips.

[0075] The third support member 21 and the fourth support member 22 are similar to the first support member 11 and the second support member 12 , and their detailed description will not be repeated here.

[0076] Although Figure 1 Only two first adjustment units 13 and two second adjustment units 23 are shown, but those skilled in the art should understand that the number of the first adjustment unit 13 and the two second adjustment units 23 is not limited thereto.

[0077] Preferably, the number of the first adjustment unit 13 and the second adjustment unit 23 can be set to three or more, which is more conducive to adjusting the inclination angle of the bottom platform 1 and the top platform 2. These first adjustment units 13 can be arranged at the bottom of the first support 11 and the second support 12 without affecting the extension and retraction of the first support 11 and the second support 12; similarly, these second adjustment units 23 can be arranged at the bottom of the third support 21 and the fourth support 22 without affecting the extension and retraction of the third support 21 and the fourth support 22.

[0078] According to an embodiment of the present invention, the first adjustment unit 13 and the second adjustment unit 23 may be motor-type adjustment units. Of course, the first adjustment unit 13 and the second adjustment unit 23 are not limited to this.

[0079] The first adjustment unit 13 and the second adjustment unit 23 may adopt the same structure. In the following, the first adjustment unit 13 will be taken as an example for detailed description.

[0080] As an example, the first adjustment unit 13 may be a gear rack adjustment structure. In this case, the first adjustment unit 13 may include a motor (not shown) and a support rod 131, wherein the motor may be disposed on the first support member 11 and the second support member 12 and a driving gear may be disposed on the driving shaft of the motor, and a rack portion may be disposed on the support rod 131, and the driving gear and the rack portion cooperate, thereby adjusting the length of the support rod 131 protruding relative to the bottom surface of the first support member 11 and the second support member 12.

[0081] Therefore, when there is a height difference between the shaft wall holes and the floor surface that cooperate with each other, the operation of the first adjustment unit 13 and / or the second adjustment unit 23 can eliminate or reduce as much as possible the problem of excessive inclination angle of the bottom platform 1 and / or the top platform 2 caused by the height difference.

[0082] And, preferably, the plurality of first adjustment units 13 are independently arranged, and the plurality of second adjustment units 23 are independently arranged, so that the inclination angles of the bottom platform 1 and the top platform 2 can be adjusted more effectively and quickly to meet various application scenarios.

[0083] According to another embodiment of the utility model, when the platform system for elevator installation of the utility model is applied to such an elevator hoistway, wherein the height of the hoistway wall hole and the floor surface that cooperate with each other is the same or the height difference between the hoistway wall hole and the floor surface that cooperate with each other is very small, in this case, multiple first adjustment units 13 can be replaced by multiple first support pads (not shown), and multiple second adjustment units 23 can be replaced by multiple second support pads (not shown). Multiple first support pads can be arranged at the bottom of the first support 11 and the second support 12 near the protruding end, and multiple second support pads can be arranged at the bottom of the third support 21 and the fourth support 22 near the protruding end. Multiple first support pads and multiple second support pads can be made of rubber material. Thus, the tilt angle of the bottom platform 1 can be slightly adjusted by the different degrees of being squeezed by the multiple first support pads, and the tilt angle of the top platform 2 can be slightly adjusted by the different degrees of being squeezed by the multiple second support pads.

[0084] According to another embodiment of the present invention, the plurality of first adjustment units 13 may be replaced by a plurality of first adjustment bolts (not shown), and the plurality of second adjustment units 23 may be replaced by a plurality of second adjustment bolts (not shown). The plurality of first adjustment bolts may be screwed to the bottom of the first support 11 and the second support 12 near the protruding end, and the plurality of second adjustment bolts may be screwed to the bottom of the third support 21 and the fourth support 22 near the protruding end. In this case, the tilt angles of the bottom platform 1 and the top platform 2 may need to be manually adjusted.

[0085] In the illustrated example, the platform system for elevator installation may further include a lifting mechanism 10, which may be disposed on the bottom platform 1 and may be connected to a target object located below the bottom platform 1. Here, the target object may be a component of an elevator, such as an elevator car.

[0086] The platform system of the utility model can be used not only for elevator installation, but also for the transportation of construction personnel and goods.

[0087] According to one embodiment of the present invention, the lifting mechanism 10 may be an electric hoist, but is not limited thereto.

[0088] The platform system for elevator installation of the utility model can control the platform system to perform corresponding operations based on the comparison result of the state information obtained by the sensor component and the predetermined state parameter, such as the extension operation and retraction operation of the jacking component 3, the pulling operation of the pulling component 4, etc. In addition, during the operation of the platform system for elevator installation, the current state of the platform system can be understood in real time based on the state information obtained by the sensor component. And, once an abnormality occurs, all operations can be stopped immediately to reduce risks as much as possible. In addition, the platform system for elevator installation of the utility model can be completely controlled by the control unit, so the operation is simpler and smarter.

[0089] Hereinafter, operations of the platform system related to various status information obtained by the sensor assembly will be described in detail.

[0090] When the comparison result between the third state information and the predetermined state parameter meets the preset condition, the control unit can be operated as follows: controlling the second driving unit of the second supporting assembly to retract the third supporting member 21 and the fourth supporting member 22 relative to the top platform 2, and then controlling the lifting assembly 3 to perform the extension operation; when the comparison result between the second state information and the predetermined state parameter meets the preset condition, the control unit can be operated as follows: controlling the lifting assembly 3 to stop performing the extension operation and then controlling the second driving unit of the second supporting assembly to extend the third supporting member 21 and the fourth supporting member 22 relative to the top platform 2; when the comparison result between the fourth state information, the fifth state information and the sixth state information and the predetermined state parameter meets the preset condition, the control unit can be operated as follows: controlling the first driving unit of the first supporting assembly to retract the first supporting member 11 and the second supporting member 12 relative to the bottom platform 1, and then controlling the lifting assembly 4 to perform the lifting operation while controlling the lifting assembly 3 to perform the retraction operation; when the comparison result between the first state information and the predetermined state parameter meets the preset condition, the control unit can be operated as follows: controlling the first driving unit of the first supporting assembly to extend the first supporting member 11 and the second supporting member 12 relative to the bottom platform 1.

[0091] When the comparison results 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 predetermined state parameters are abnormal, the control unit can control the platform system to stop running.

[0092] When the comparison result between the fourth state information and the predetermined state parameters does not meet the preset conditions but meets the adjustment conditions, the control unit can be operated to control the first adjustment unit 13 and the second adjustment unit 23 to adjust the inclination angles of the bottom platform 1 and the top platform 2 until the comparison result between the fourth state information and the predetermined state parameters meets the preset conditions.

[0093] According to an embodiment of the present invention, the control unit may be arranged on the bottom platform, and an operator may stand on the bottom platform to operate the platform system of the present invention.

[0094] According to another embodiment of the present invention, the control unit may be arranged on the bottom platform or the top platform, and the control unit may be connected to a remote control device via a signal, so that an operator may remotely control the platform system of the present invention.

[0095] In the following, we will refer to Figures 2 to 8 The operating process and control method of the platform system for elevator installation of the utility model are described.

[0096] like Figures 2 to 8 As shown in the figure, the bottom platform 1 and the top platform 2 are respectively raised by one floor height in the vertical direction under the action of the driving element of the platform system. However, those skilled in the art should understand that the rising height of each operation of the platform system of the utility model is not limited to this, and the platform system can not only perform the rising operation, but also the descending operation.

[0097] Mate Reference Figure 2 , the bottom platform is at level N, the top platform is at level N+1, N is a natural number, preferably, before the platform system performs an ascending operation, the control unit compares the current first state information, second state information, third state information, fourth state information, fifth state information and sixth state information with the predetermined state parameters and obtains a comparison result, thereby determining whether the various components in the platform system are in an appropriate position or state at this time, so as to avoid affecting subsequent related operations. An ascending operation of the platform system can be roughly divided into the following steps:

[0098] S1: The optical sensor monitors whether there is an obstacle above the top platform. When the comparison result between the third state information and the predetermined state parameter satisfies the preset condition, that is, there is no obstacle above the top platform, in this case, the control unit controls the second driving unit to retract the third support member and the fourth support member, such as Figure 3 As shown;

[0099] S2: The control unit controls the jacking assembly to make the top platform start to move upward. At this time, based on the comparison result of the second state information and the predetermined state parameter, it can be judged whether the top platform has moved to the appropriate position (for example, the height of the layer station N+2). When the comparison result of the second state information and the predetermined state parameter meets the preset condition, that is, the top platform has moved to the appropriate position, which also means that the extension operation of the jacking assembly has been completed. Accordingly, the control unit controls the jacking assembly to stop continuing to perform the extension operation, such as Figure 4 As shown;

[0100] S3: The control unit controls the second driving unit to extend the third support member and the fourth support member. Figure 5 As shown;

[0101] S4: The control unit needs to determine whether to continue the subsequent operation based on the comparison results of the fourth state information, the fifth state information and the sixth state information with the predetermined state parameters, wherein when the comparison results of the fourth state information, the fifth state information and the sixth state information with the predetermined state parameters meet the preset conditions, that is, the inclination angle of the top platform meets the relevant requirements, the third support member and the fourth support member have been stably supported on the floor and the shaft wall hole, and the target object carried by the bottom platform is not overweight, in this case, the control unit controls the first driving unit to retract the first support member and the second support member, such as Figure 6 As shown;

[0102] S5: The control unit controls the lifting assembly to make the bottom platform start to move upward. At this time, based on the comparison result of the first state information and the predetermined state parameter, it can be judged whether the bottom platform has moved to the appropriate position (for example, the height of the layer station N+1). When the comparison result of the first state information and the predetermined state parameter meets the preset condition, that is, the bottom platform has moved to the appropriate position, which also means that the lifting operation of the lifting assembly has been completed. Accordingly, the control unit controls the lifting assembly to stop continuing to perform the lifting operation. In addition, while controlling the lifting assembly to perform the lifting operation, the control unit also controls the jacking assembly to perform the retraction operation, such as Figure 7 As shown;

[0103] S6: The control unit controls the first driving unit to extend the first support member and the second support member, such as Figure 8 as shown; and

[0104] S7: The control unit needs to determine whether the platform system has completed an ascending operation based on the comparison results of the fourth state information and the fifth state information with the predetermined state parameters, wherein when the comparison results of the fourth state information and the fifth state information with the predetermined state parameters meet the preset conditions, that is, the inclination angle of the bottom platform meets the relevant requirements and the first support member and the second support member have been stably supported on the floor and the shaft wall hole, in this case, it can be determined that the platform system has completed an ascending operation.

[0105] In step S4, when the comparison result between 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 relevant requirements but is within the adjustable range, in this case, the control unit can adjust the inclination angle of the top platform by controlling the second adjustment unit until the inclination angle of the top platform meets the relevant requirements.

[0106] In step S7, when the comparison result between 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 relevant requirements but is within the adjustable range, in this case, the control unit can adjust the inclination angle of the bottom platform by controlling the first adjustment unit until the inclination angle of the bottom platform meets the relevant requirements.

[0107] During the entire operation of the platform system, once the comparison results 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 predetermined state parameters are abnormal, the control unit immediately controls the platform system to stop running, thereby reducing operational risks.

[0108] In addition, according to another embodiment of the present invention, the first support and the second support may be provided with sensors configured to monitor the lengths of the first support and the second support protruding from the bottom platform, thereby determining whether the operations of the first support and the second support in steps S4 and S6 have been correctly performed based on the status information obtained by the sensors. Similarly, the third support and the fourth support may also be provided with sensors configured to monitor the lengths of the third support and the fourth support protruding from the top platform, thereby determining whether the operations of the third support and the fourth support have been correctly performed.

[0109] In addition, according to another embodiment of the utility model, the platform system for elevator installation may further include an optically assisted installation module and a drone module, wherein the optically assisted installation module can be used for the installation and positioning of elevator components; the drone module can collect spatial information of the elevator shaft for installing the elevator and send the collected spatial information to the control unit; then the control unit simulates the shaft layout of the elevator installation based on the received spatial information and determines whether the current elevator shaft meets the elevator installation requirements.
