[0037] It should be understood that the accompanying drawings are not drawn to scale, but rather illustrate various features that are presented in a slightly simplified manner to explain the basic principles of the invention. In the accompanying drawings of this invention, the same reference numerals denote the same or equivalent parts of the invention.

[0038] Reference will now be made in detail to various embodiments of the invention, examples of which are shown in the accompanying drawings and described below. Although the invention will be described in conjunction with exemplary embodiments thereof, it will be understood that this specification is not intended to limit the invention to those exemplary embodiments. On the contrary, the invention is intended to cover not only the exemplary embodiments thereof, but also various alternatives, modifications, equivalents, and other embodiments included within the spirit and scope of the invention as defined in the appended claims.

[0039] The specific structural and functional descriptions of the embodiments of the present invention disclosed herein are for illustrative purposes only. The present invention can be implemented in many different forms without departing from its spirit and essential features. Therefore, the embodiments of the present invention are disclosed for illustrative purposes only and should not be construed as limiting the invention.

[0040] Although the terms "first," "second," etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the teachings of the invention, the first element discussed below may be referred to as the second element. Similarly, the second element may also be referred to as the first element.

[0041] Certain terms are used throughout the application documents of this invention to refer to specific system components. As those skilled in the art will recognize, the same components can often be referred to by different names, and therefore the application documents of this invention are not intended to distinguish those components that differ only in name and not in function. In the document documents of this invention, the terms “comprising,” “including,” and “having” are used in an open form and should therefore be interpreted as meaning “including but not limited to…”.

[0042] In the following, exemplary embodiments of the invention will be described in more detail with reference to the accompanying drawings.

[0043] Figure 1This is a schematic diagram of the structure of a platform system for elevator installation according to an exemplary embodiment of the present invention. Figures 2 to 8 This is a schematic diagram illustrating the state of a platform system for elevator installation during operation, as an exemplary embodiment of the present invention.

[0044] Reference Figures 1 to 8 The platform system for elevator installation according to an exemplary embodiment of the present invention can be applied in an elevator shaft and can be supported by floor surfaces and shaft wall openings, which are arranged vertically and spaced apart from each other by a predetermined distance. The vertical direction refers to the height direction of the elevator shaft. Typically, the vertical position of each of the plurality of shaft wall openings substantially corresponds to the vertical position of the corresponding floor surface; here, "corresponds" means that the heights of the corresponding shaft wall openings and the floor surface are the same or the height difference between the corresponding shaft wall openings and the floor surface is within a specified range.

[0045] According to an exemplary embodiment of the present invention, 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. The top platform 2 is located above the bottom platform 1, and the top platform 2 and the bottom platform 1 are vertically spaced apart. The climbing mechanism is disposed between the bottom platform 1 and the top platform 2 and configured to adjust the vertical height of the bottom platform 1 and the top platform 2. 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. The control unit compares the received state information with predetermined state parameters and controls the platform system to perform corresponding operations based on the comparison result.

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

[0047] Furthermore, the climbing mechanism of an exemplary embodiment of the present invention may include: a lifting component 3 and a pulling component 4, wherein the lifting component 3 is mounted on the top of the bottom platform 1, the lifting component 3 is a one-way driven telescopic component, and the top platform 2 moves vertically based on the extension operation of the lifting component 3 (see reference). Figure 4 The lifting assembly 4 is installed at the bottom of the top platform 2. After the extension operation of the lifting assembly 3 is completed, the lifting assembly 4 performs a lifting operation to move the bottom platform 1 vertically, while the lifting assembly 3 performs a retraction operation (see reference). 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 and retraction operations 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 lifting assembly 3 to perform an upward extension operation, the lifting assembly 3 pushes against the top platform 2 to move the top platform 2 upward; when the control unit controls the lifting assembly 4 to perform a lifting operation, the lifting assembly 4 lifts the bottom platform 1 to move the bottom platform 1 upward, while the lifting assembly 3 performs a retraction operation; thus, through the cooperation of the lifting assembly 3 and the lifting assembly 4, the top platform 2 and the bottom platform 1 move in the vertical direction.

[0049] In the example shown, the lifting component 3 is a hydraulically driven component, and the pulling component 4 is an electric hoist. However, those skilled in the art should understand that the structures of the lifting component 3 and the pulling component 4 are not limited thereto, and any other structure that can achieve the same technical effect is acceptable. For example, the lifting component 3 can also be a worm gear component, a gear / rack drive component, or a screw component, etc., and the pulling component 4 can also be a manual hoist, etc. Any other equivalent solutions that those skilled in the art can conceive of are included within the concept of this invention, and will not be described in detail here.

[0050] Furthermore, although the number of lifting component 3 and lifting component 4 is set to one in the example shown, the number of lifting component 3 and lifting component 4 can be set to multiple depending on the actual application, and the number of lifting component 3 and lifting component 4 can be different from each other to suit various application scenarios.

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

[0052] Alternatively, one end of the lifting assembly 3 can be fixedly mounted on the bottom platform 1, and the other end of the lifting assembly 3 can also be fixedly mounted on 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 lifting 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 drive mechanism.

[0054] As an example, the climbing mechanism can be a motor-driven screw-sleeve structure, where the screw and sleeve constitute a telescopic assembly, one end of which is connected to the bottom platform 1 and the other end to the top platform 2. When the motor's drive shaft rotates in a first direction, the telescopic assembly of the screw and sleeve extends, thereby pushing against the top platform 2 to move it upward until it reaches the appropriate position and is supported by the floor and the shaft wall hole. When the motor's drive shaft rotates in a second direction, the telescopic assembly of the screw and sleeve shortens, thereby lifting the bottom platform 1 to move it upward until it reaches the appropriate position. The second direction is opposite to the first direction; for example, the first direction can be clockwise and the second direction can be counterclockwise, and vice versa. Therefore, by rotating the motor's drive shaft in two opposite directions, the vertical height of the bottom platform 1 and the top platform 2 can be adjusted. Of course, the manifestation of the bidirectional drive mechanism is not limited to this.

[0055] According to an exemplary embodiment of the present invention, the sensor assembly may include: a height sensor 5, an optical sensor 6, a tilt angle sensor 7, a pressure sensor 8, and a mass sensor 9. The height sensor 5 is disposed on a bottom platform 1 and a top platform 2, and 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 disposed on the top platform 2, and is configured to monitor whether an obstacle exists above the top platform 2 to obtain third state information related to the obstacle. The tilt angle sensor 7 is disposed on the bottom platform 1 and the top platform 2, and is configured to monitor the heights of the bottom platform 1 and the top platform 2 to obtain third state information related to the obstacle. The tilt angles of the bottom platform 1 and the top platform 2 relative to the horizontal direction are used to obtain fourth state information related to the tilt angle; pressure sensors 8 are installed on the bottom platform 1 and the top platform 2, and are configured to monitor whether the bottom platform 1 and the top platform 2 are stably supported to obtain fifth state information related to the support state; mass sensors 9 are installed on the bottom platform 1, and are 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 predetermined state parameters and controls the platform system to perform corresponding operations based on the comparison results.

[0056] Furthermore, the platform system for elevator installation according to an exemplary embodiment of the present invention may further include a first support assembly disposed on the bottom platform 1 and a second support assembly disposed on 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 drive unit, wherein the first support member 11 may be disposed on the first side of the bottom platform 1, as shown below. Figure 1 As shown on the left side; the second support member 12 can be disposed on the second side of the bottom platform 1 opposite to the first side, as shown here. Figure 1 As shown on the right side; 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 drive unit can be a motor-driven drive unit, and the connection between the first drive unit and the first support member 11 and the second support member 12 can be a gear and rack connection structure. Thus, by rotating the drive shaft of the motor, the gear connected to the drive shaft engages with the rack portion on the first support member 11 and the second support member 12, allowing adjustment of 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. Of course, the form of the first drive unit is not limited to this.

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

[0060] According to another embodiment of the invention, the first support member 11 and the second support member 12 can 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 drive unit, wherein the third support member 21 may be disposed on the first side of the top platform 2, as shown below. Figure 1 As shown on the left side; the fourth support member 22 can be disposed on the second side of the top platform 2 opposite to the first side, as shown here. Figure 1 As shown on the right side; a second drive unit (not shown) may be disposed in the top platform 2 and configured to extend or retract the third support 21 and the fourth support 22 relative to the top platform 2.

[0062] Similarly, the second drive unit can be a motor-driven drive unit, and the connection between the second drive unit and the third support member 21 and the fourth support member 22 can be a gear and rack connection structure. Thus, by rotating the drive shaft of the motor, the gear connected to the drive shaft engages with the rack portions on the third support member 21 and the fourth support member 22, allowing adjustment of 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. Of course, the form of the second drive unit is not limited to this.

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

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

[0065] Furthermore, the first drive unit of the first support assembly and the second drive unit of the second support assembly can be electrically connected to the control unit, so that the first drive unit and the second drive unit are controlled by the control unit.

[0066] In the example shown, pressure sensor 8 can 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 in the illustrated example the pressure sensor 8 is disposed on the top surface of the first support 11, the second support 12, the third support 21 and the fourth support 22, those skilled in the art should understand that the pressure sensor 8 may also be disposed inside the first support 11, the second support 12, the third support 21 and the fourth support 22, and the form of the pressure sensor 8 is not limited thereto.

[0068] Furthermore, methods for determining whether the bottom platform 1 and the top platform 2 are stably supported are not limited to pressure sensors.

[0069] According to an exemplary embodiment of the present invention, the first support assembly may further include a first adjustment unit 13 disposed at the bottom of the first support member 11 and the second support member 12 near their extended ends. Similarly, the second support assembly may further include a second adjustment unit 23 disposed at the bottom of the third support member 21 and the fourth support member 22 near their extended ends. Furthermore, the first adjustment unit 13 and the second adjustment unit 23 may be electrically connected to a control unit, such that the control unit can be operated to adjust the vertical length of the first adjustment unit 13 and the second adjustment unit 23 to adjust the tilt angle of the bottom platform 1 and the top platform 2.

[0070] Here, the protruding 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 that are away from the bottom platform 1, in accordance with reference. Figure 1 As shown, the first adjustment unit 13 is located at the bottom of the first support member 11 near the left end and at the bottom of the second support member 12 near the right end; the protruding 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, in accordance with reference. Figure 1 As shown, the second adjustment unit 23 is located 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 The diagram shows a platform system for elevator installation in cross-sectional view, wherein the bottom platform 1 and the top platform 2 have rectangular cross-sections. However, those skilled in the art will appreciate that when the bottom platform 1 and the top platform 2 are viewed from a top or bottom view, they may have square top and bottom surfaces.

[0072] According to one embodiment of the present invention, the number of first support members 11 disposed on the first side (left side) of the bottom platform 1 can be set to one, and the number of second support members 12 disposed 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] Furthermore, 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 portions of the first support member 11 and the second support member 12 can be supported on the floor and the shaft wall hole, respectively.

[0074] According to another embodiment of the present invention, the number of first support members 11 disposed on the first side (left side) of the bottom platform 1 can be multiple, and the number of second support members 12 disposed on the second side (right side) of the bottom platform 1 can be 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 will not be described again here.

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

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

[0078] According to one embodiment of the present invention, the first adjustment unit 13 and the second adjustment unit 23 can be motor-driven adjustment units. Of course, the form of the first adjustment unit 13 and the second adjustment unit 23 is not limited thereto.

[0079] The first adjustment unit 13 and the second adjustment unit 23 can adopt the same structure. In the following text, the first adjustment unit 13 will be used as an example for detailed explanation.

[0080] As an example, the first adjustment unit 13 can be a gear and 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 drive gear may be disposed on the drive shaft of the motor, and a rack portion may be disposed on the support rod 131, the drive gear cooperating with the rack portion, 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 cooperating shaft wall holes and the floor, the operation of the first adjustment unit 13 and / or the second adjustment unit 23 can eliminate or mitigate the problem of excessive tilt angle of the bottom platform 1 and / or the top platform 2 caused by the height difference as much as possible.

[0082] Furthermore, preferably, the multiple first adjustment units 13 are arranged independently of each other, and the multiple second adjustment units 23 are arranged independently of each other, so that the tilt angle 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 invention, when the platform system for elevator installation of the invention is applied to an elevator shaft where the heights of the mating shaft wall holes and the floor level are the same or the height difference between the mating shaft wall holes and the floor level is very small, in this case, the plurality of first adjustment units 13 can be replaced by a plurality of first support pads (not shown), and the plurality of second adjustment units 23 can be replaced by a plurality of second support pads (not shown). The plurality of first support pads can be disposed at the bottom near the protruding ends of the first support member 11 and the second support member 12, and the plurality of second support pads can be disposed at the bottom near the protruding ends of the third support member 21 and the fourth support member 22. The plurality of first support pads and the plurality of second support pads can be made of rubber material. Thus, by varying degrees of compression of the plurality of first support pads, the tilt angle of the bottom platform 1 can be slightly adjusted, and by varying degrees of compression of the plurality of second support pads, the tilt angle of the top platform 2 can be slightly adjusted.

[0084] According to another embodiment of the invention, the plurality of first adjustment units 13 can be replaced by a plurality of first adjustment bolts (not shown), and the plurality of second adjustment units 23 can be replaced by a plurality of second adjustment bolts (not shown). The plurality of first adjustment bolts can be screwed to the bottom of the first support member 11 and the second support member 12 near their protruding ends, and the plurality of second adjustment bolts can be screwed to the bottom of the third support member 21 and the fourth support member 22 near their protruding ends. In this case, it may be necessary to manually adjust the tilt angle of the bottom platform 1 and the top platform 2.

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

[0086] The platform system of this invention 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 can be an electric hoist, but is not limited thereto.

[0088] The elevator installation platform system of the present invention can control the platform system to perform corresponding operations based on the comparison results of state information obtained by sensor components and predetermined state parameters, such as the extension and retraction operations of the lifting component 3 and the lifting operation of the pulling component 4. Furthermore, during the operation of the elevator installation platform system, the current state of the platform system can be understood in real time based on the state information obtained by the sensor components. And, in the event of an anomaly, all operations can be stopped immediately to minimize risks. Moreover, the elevator installation platform system of the present invention can be completely controlled by the control unit, thus making operation simpler and more intelligent.

[0089] The following section will describe in detail the operation of the platform system related to the various state information obtained by the sensor components.

[0090] When the comparison result of the third state information and the predetermined state parameters meets the preset conditions, the control unit can operate as follows: control the second drive unit of the second support assembly to retract the third support member 21 and the fourth support member 22 relative to the top platform 2, and then control the lifting assembly 3 to perform the extension operation; when the comparison result of the second state information and the predetermined state parameters meets the preset conditions, the control unit can operate as follows: control the lifting assembly 3 to stop performing the extension operation and then control the second drive unit of the second support assembly to extend the third support member 21 and the fourth support member 22 relative to the top platform 2; 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, the control unit can operate as follows: control the first drive unit of the first support assembly to retract the first support member 11 and the second support member 12 relative to the bottom platform 1, and then control the lifting assembly 4 to perform the lifting operation while controlling the lifting assembly 3 to perform the retraction operation; when the comparison result of the first state information and the predetermined state parameters meets the preset conditions, the control unit can operate as follows: control the first drive unit of the first support assembly to extend the first support member 11 and the second support member 12 relative to the bottom platform 1.

[0091] When the comparison results of the first, second, third, fourth, fifth, and sixth state information with the predetermined state parameters are abnormal, the control unit can control the platform system to stop operating.

[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 operate to control the first adjustment unit 13 and the second adjustment unit 23 to adjust the tilt angle 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 one embodiment of the present invention, the control unit can be installed on the bottom platform, and the operator can stand on the bottom platform to operate the platform system of the present invention.

[0094] According to another embodiment of the invention, the control unit can be located on the bottom platform or the top platform, and the control unit can be signal-connected to a remote control device, thereby allowing the operator to remotely control the platform system of the invention.

[0095] In the following text, references will be provided. Figures 2 to 8 The operation process and control method of the platform system for elevator installation of the present invention are described.

[0096] like Figures 2 to 8 As shown, the bottom platform 1 and the top platform 2 rise vertically by one floor height under the action of the driving elements of the platform system. However, those skilled in the art will understand that the rising height of the platform system of the present invention in each operation is not limited to this, and the platform system can not only perform rising operations, but also lowering operations.

[0097] Reference Figure 2 The bottom platform is at station N, and the top platform is at station N+1, where N is a natural number. Preferably, before the platform system performs an ascent operation, the control unit compares the current first, second, third, fourth, fifth, and sixth state information with predetermined state parameters and obtains the comparison results. This allows the control unit to determine whether each component in the platform system is in the appropriate position or state, thus avoiding interference with subsequent operations. A single ascent operation of the platform system can be broadly divided into the following steps:

[0098] S1: The optical sensor monitors whether there are obstacles above the top platform. When the comparison result of the third state information and the predetermined state parameters meets the preset conditions, that is, there are no obstacles above the top platform, the control unit controls the second drive unit to retract the third and fourth support members, as shown below. Figure 3 As shown;

[0099] S2: The control unit controls the lifting assembly to start the top platform moving upward. At this time, based on the comparison result of the second state information and the predetermined state parameters, it can be determined whether the top platform has moved to the appropriate position (e.g., the height of floor N+2). When the comparison result of the second state information and the predetermined state parameters meets the preset conditions, that is, the top platform has moved to the appropriate position, which also means that the extension operation of the lifting assembly has been completed. Accordingly, the control unit controls the lifting assembly to stop continuing to perform the extension operation. Figure 4 As shown;

[0100] S3: The control unit controls the second drive unit to extend the third and fourth support members, such as... Figure 5 As shown;

[0101] S4: The control unit needs to determine whether to continue subsequent operations based on the comparison results of the fourth, fifth, and sixth state information with predetermined state parameters. Specifically, when the comparison results of the fourth, fifth, and sixth state information with predetermined state parameters meet preset conditions—that is, the tilt angle of the top platform meets relevant requirements, the third and fourth supports are stably supported on the floor and shaft wall holes, and the target object carried by the bottom platform is not overweight—the control unit controls the first drive unit to retract the first and second supports. Figure 6 As shown;

[0102] S5: The control unit controls the lifting assembly to start the bottom platform moving upward. At this time, based on the comparison result of the first state information and the predetermined state parameters, it can be determined whether the bottom platform has moved to the appropriate position (e.g., the height of floor N+1). When the comparison result of the first state information and the predetermined state parameters meets the preset conditions, 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 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. Figure 7 As shown;

[0103] S6: The control unit controls the first drive 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 a lifting operation based on the comparison results of the fourth state information and the fifth state information with the predetermined state parameters. 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 tilt angle of the bottom platform meets the relevant requirements and the first support and the second support are stably supported on the floor and the shaft wall hole, it can be determined that the platform system has completed a lifting operation.

[0105] In step S4, 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, that is, the tilt angle of the top platform does not meet the relevant requirements but is within the adjustable range, the control unit can adjust the tilt angle of the top platform by controlling the second adjustment unit until the tilt 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 parameters does not meet the preset conditions but meets the adjustment conditions, that is, the tilt angle of the bottom platform does not meet the relevant requirements but is within the adjustable range, the control unit can adjust the tilt angle of the bottom platform by controlling the first adjustment unit until the tilt angle of the bottom platform meets the relevant requirements.

[0107] Throughout the operation of the platform system, if any of the comparison results between the first, second, third, fourth, fifth, and sixth state information and the predetermined state parameters are abnormal, the control unit will immediately stop the platform system from operating, thereby reducing operational risks.

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

[0109] Furthermore, according to another embodiment of the present invention, the platform system for elevator installation may further include an optical auxiliary installation module and a drone module, wherein the optical auxiliary 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 elevator installation and send the collected spatial information to the control unit; then the control unit simulates the elevator shaft layout based on the received spatial information and determines whether the current elevator shaft meets the elevator installation requirements.
