In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified. In the description of the embodiments of this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, B1 and / or B2 can represent: B1 existing alone, B1 and B2 existing simultaneously, and B2 existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] The following is combined with Figures 1 to 15 The present invention describes the lifting device and the lifting and rotating transport platform.

[0043] In the first aspect, such as Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a lifting device 1, including a lifting body 11 and a mounting frame 12; The lifting body 11 is used to move up and down along the guide rail 2. The mounting frame 12 is used to attach to the transport platform 3. The mounting frame 12 is rotatably connected to the lifting body 11. The mounting frame 12 is configured to rotate relative to the lifting body 11 about the vertical axis to transfer the transport platform 3 to different lateral positions of the lifting body 11.

[0044] Understandably, the guide rail 2 is used to guide the lifting of the lifting body 11 in the vertical direction, and the guide rail 2 can be attached to the current construction surface of the overlapping structure.

[0045] The lifting body 11 can be a traction-type lifting device or a gear climber, and there is no specific limitation on this. The lifting body 11 can be set on one side of the guide rail 2 or sleeved on the outside of the guide rail 2, and there is no specific limitation on this.

[0046] The lifting body 11 and the mounting frame 12 are rotatably connected by a hinge structure, which guides the mounting frame 12 to rotate relative to the lifting body 11 around a vertical axis. To ensure that the mounting frame 12 can stably and reliably support the transport platform 3 and rotate relative to the lifting body 11, multiple hinge structures can be provided, with the multiple hinge structures spaced apart along the vertical direction.

[0047] For example, the hinge structure includes a first hinge ear, a second hinge ear, and a hinge shaft. The first hinge ear is disposed on the lifting body 11, and the second hinge ear is disposed on the mounting frame 12. The first hinge ear and the second hinge ear are rotatably connected by hinge shafts distributed in the vertical direction.

[0048] In practical applications, the mounting frame 12 can be manually controlled by the operator to rotate relative to the lifting body 11, or the rotating mechanism can drive the mounting frame 12 to rotate relative to the lifting body 11. There are no specific limitations on this.

[0049] The lifting device 1 shown in this invention, by setting up a lifting body 11 and a mounting frame 12, and attaching the mounting frame 12 to the transport platform 3, can ensure that the entire lifting device 1 carries the transport platform 3 to the target working level based on the lifting movement of the lifting body 11 along the guide rail 2. Based on the flip setting of the mounting frame 12 relative to the lifting body 11, the mounting frame 12 drives the transport platform 3 to flip to the target working surface, which facilitates the transfer of personnel or materials carried by the transport platform 3 to the target working surface. This design meets the personnel / material transfer needs of different working surfaces and makes it convenient for operators to flexibly carry out construction operations on different working surfaces.

[0050] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the mounting frame 12 rotates between the initial position and the target position relative to the lifting body 11; When the mounting frame 12 is in the initial position, the mounting frame 12 is in contact with the lifting body 11, and the lifting body 11 and the mounting frame 12 are connected by the first locking structure 101. When the mounting frame 12 is in the target position, the mounting frame 12 and the lifting body 11 are set at an angle, and the lifting body 11 and the mounting frame 12 are connected by the second locking structure 102.

[0051] It is understandable that when the mounting frame 12 is in the initial position, the mounting frame 12 does not rotate relative to the lifting body 11, so the mounting frame 12 and the lifting body 11 remain in contact. Based on the first locking structure 101 connecting the mounting frame 12 and the lifting body 11 into one unit, the safety of the entire lifting equipment 1 in supporting the lifting of the transport platform 3 on the current construction surface can be ensured.

[0052] When the mounting frame 12 is in the target position, the mounting frame 12 rotates relative to the lifting body 11 by a preset angle (for example, the preset angle is 0° to 270°), so that the mounting frame 12 and the lifting body 11 are set at an angle. The transport platform 3 mounted on the mounting frame 12 reaches the position of docking with the target construction surface. At this time, the mounting frame 12 and the lifting body 11 are connected as one unit based on the second locking structure 102, thereby ensuring that personnel or materials on the transport platform 3 can be safely transferred to the target construction surface at the docking position.

[0053] In some application scenarios, the mounting frame 12 can rotate between 0° and 90° relative to the lifting body 11; when the mounting frame 12 is in the initial position, the rotation angle of the mounting frame 12 relative to the lifting body 11 is 0°, and when the mounting frame 12 is in the target position, the rotation angle of the mounting frame 12 relative to the lifting body 11 is 90°.

[0054] In some embodiments, such as Figure 5 and Figure 6 As shown, at least one of the first locking structure 101 and the second locking structure 102 includes a locking pin 1021, a rotating handle 1022, and a locking hook 1023; for ease of description, the second locking structure 102 will be used as an example for specific explanation below.

[0055] For the second locking structure 102, a locking pin 1021 is disposed on the lifting body 11, a rotating handle 1022 is rotatably disposed on the mounting frame 12, and a locking hook 1023 is disposed on the rotating handle 1022. The locking hook 1023 is used to engage or disengage with the locking pin 1021 under the action of the rotating handle 1022. When the locking hook 1023 and the locking pin 1021 are engaged, the lifting body 11 and the mounting frame 12 are locked together. When the locking hook 1023 and the locking pin 1021 are disengaged, the lifting body 11 and the mounting frame 12 are released from the locking connection, and only then can the mounting frame 12 be rotated relative to the lifting body 11.

[0056] In practical applications, when both the first locking structure 101 and the second locking structure 102 include a locking pin 1021, a rotating handle 1022, and a locking hook 1023, the locking pin 1021 can be configured to include a first locking pin 1021 and a second locking pin 1021. Considering that the mounting frame 12 needs to rotate relative to the lifting body 11, the first locking pin 1021 and the second locking pin 1021 are positioned differently on the lifting body 11. Meanwhile, the locking hook 1023 includes a first locking hook 1023 and... The second locking hook 1023, the first locking pin 1021 and the first locking hook 1023 are arranged opposite to each other, the second locking pin 1021 and the second locking hook 1023 are arranged opposite to each other, the first locking hook 1023 and the second locking hook 1023 are respectively connected to the rotating handle 1022, that is, the first locking pin 1021, the first locking hook 1023 and the rotating handle 1022 form the first locking structure 101, and the second locking pin 1021, the second locking hook 1023 and the rotating handle 1022 form the second locking structure 102.

[0057] like Figure 5 and Figure 6 As shown, when the mounting frame 12 is in the initial position, the operator can manually rotate the rotating handle 1022, for example, by controlling the rotating handle 1022 to rotate clockwise, so that the first locking hook 1023 and the first locking pin 1021 can be engaged, thereby locking the lifting body 11 and the mounting frame 12 into one unit, ensuring that the mounting frame 12 is maintained in the initial position.

[0058] like Figure 6 and Figure 7 As shown, when the mounting frame 12 switches from the initial position to the target position, the operator can manually rotate the rotating handle 1022, for example, by controlling the rotating handle 1022 to rotate counterclockwise, so that the second locking hook 1023 and the second locking pin 1021 can be engaged to lock the lifting body 11 and the mounting frame 12 into one unit, ensuring that the mounting frame 12 is maintained in the target position.

[0059] In some embodiments, such as Figure 5 As shown, the lifting device 1 also includes a position detection component 103, which is communicatively connected to the lifting body 11. The position detection component 103 is used to detect whether the mounting frame 12 is in the initial position.

[0060] It is understandable that the position detection component 103 can be a photoelectric switch or a limit switch, and there are no specific limitations on this.

[0061] In practical applications, if the position detection component 103 detects that the mounting frame 12 is not in its initial position when no flipping action is performed on the mounting frame 12, the lifting body 11 will determine that the mounting frame 12 and the lifting body 11 are not connected as one unit based on the detection information of the position detection component 103, and the lifting body 11 will not start operation, thus ensuring the safety of the entire lifting equipment 1.

[0062] In some embodiments, such as Figure 5 As shown, the lifting device 1 also includes a weighing sensor 104, which is disposed between the lifting body 11 and the mounting frame 12 to detect the load information of the mounting frame 12.

[0063] Understandably, based on the load information detected by the load sensor 104, the load on the mounting frame 12 can be monitored in real time, preventing overloading. In practical applications, the load sensor 104 can be configured to communicate with the lifting body 11. When the load detected by the load sensor 104 exceeds the set load, the lifting body 11 will not start operation, ensuring the safety of the entire lifting equipment 1.

[0064] It should be noted that, in the case where the hinge structure between the lifting body 11 and the mounting frame 12 includes a first hinge ear, a second hinge ear, and a hinge shaft, in order to facilitate the detection of the load information of the mounting frame 12, the load sensor 104 can be configured as a ring, with the load sensor 104 sleeved on the outside of the hinge shaft and abutting between the first hinge ear and the second hinge ear.

[0065] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, one side of the lifting body 11 is rotatably connected to one side of the mounting frame 12; the mounting frame 12 is provided with a first mounting part 120 on the side opposite to the lifting body 11, and the first mounting part 120 is used to mount with the second mounting part 301 of the transport platform 3.

[0066] It is understandable that by setting one side of the lifting body 11 to be rotatably connected to one side of the mounting frame 12, it is easy to ensure that the mounting frame 12 can be rotated at a large angle relative to the lifting body 11. For example, the mounting frame 12 can be rotated between 0° and 270° relative to the lifting body 11.

[0067] At the same time, such as Figure 3 As shown, based on the design of the first attachment part 120 and the second attachment part 301, it is convenient to quickly attach the transport platform 3 to one side of the mounting frame 12. In addition, combined with the rotation setting between the lifting body 11 and the mounting frame 12, it is not easy for the transport platform 3 to interfere with the lifting body 11 during the process of the mounting frame 12 carrying the transport platform 3 and turning.

[0068] In order to ensure that the mounting frame 12 and the transport platform 3 are reliably connected as one unit, multiple first mounting parts 120 and multiple second mounting parts 301 can be provided, and multiple first mounting parts 120 and multiple second mounting parts 301 are connected one-to-one.

[0069] In practical applications, such as Figure 1 As shown, the lifting body 11 is located on one side of the guide rail 2. When the mounting frame 12 is in the initial position, considering that the mounting frame 12 is in contact with the lifting body 11, the transport platform 3 is located on the side of the entire lifting equipment 1 away from the guide rail 2.

[0070] like Figure 7 and Figure 14 As shown, when the mounting frame 12 is in the target position, the mounting frame 12 and the transport platform 3 are located on the same side of the lifting body 11 and the guide rail 2. That is, the lifting body 11 and the guide rail 2 are on one construction surface, and the mounting frame 12 and the transport platform 3 are on another construction surface. These two construction surfaces can be vertically distributed.

[0071] In some embodiments, such as Figure 7 As shown, the first hook 120 is a hook, and the second hook 301 is a hook shaft; the mounting frame 12 is also provided with an anti-detachment structure 121, which includes a locking arm 1211 and a first elastic member 1212; the locking arm 1211 is rotatably mounted on the hook; the first elastic member 1212 can be a spring, and the first elastic member 1212 is connected between the locking arm 1211 and the hook to drive the locking end of the locking arm 1211 to stop at the hook opening.

[0072] Understandably, when the hook shaft is not hooked into the hook, the locking end of the locking arm 1211 is positioned to stop at the hook opening under the resistance of the first elastic element 1212.

[0073] During the process of hooking the axle into the hook, the axle presses down on the locking end of the locking arm 1211 to drive the locking arm 1211 to swing against the elastic force of the first elastic element 1212 (e.g., swinging clockwise) until the axle passes over the axle and enters the hook. At this time, the locking arm 1211 swings in the opposite direction under the elastic force of the first elastic element 1212 (e.g., swinging counterclockwise), so that the locking end of the locking arm 1211 is once again in the position of stopping at the hook opening to prevent the axle from detaching from the hook.

[0074] In some embodiments, the lifting device 1 further includes a tilting mechanism disposed between the lifting body 11 and the mounting frame 12 to drive the mounting frame 12 to tilt relative to the lifting body 11.

[0075] In practical applications, the flipping mechanism can be a telescopic rod, such as an electric push rod. The first end of the telescopic rod is rotatably connected to the lifting body 11, and the second end of the telescopic rod is rotatably connected to the mounting frame 12. Based on the extension and retraction of the telescopic rod, the mounting frame 12 can be driven to flip relative to the lifting body 11.

[0076] Of course, the tilting mechanism can also include a drive motor and a gear transmission assembly. The gear transmission assembly includes a first gear and a second gear. The drive motor is mounted on the lifting body 11, and its output end is coaxially connected to the first gear. The first and second gears mesh with each other. The second gear is coaxially mounted on the hinge shaft between the lifting body 11 and the mounting frame 12, and the hinge shaft is fixedly connected to the mounting frame 12. In this way, the drive motor can drive the mounting frame 12 to tilt relative to the lifting body 11 through the gear transmission assembly.

[0077] In some embodiments, such as Figure 2 and Figure 6 As shown, the lifting body 11 includes a lifting seat 111, a drive mechanism 112, and a fall arrester 113. The lifting seat 111 is disposed on one side of the guide rail 2 and is movably disposed along the guide rail 2. A rack 23 is formed along the extension direction of the guide rail 2. The drive mechanism 112 is disposed on the lifting seat 111 and has a drive gear that meshes with the rack 23. The fall arrester 113 is disposed on the lifting seat 111 and has a fall arrester gear that meshes with the rack 23.

[0078] It is understood that the drive mechanism 112 may include a rotary drive component and a drive gear. The rotary drive component may be a geared motor. The output shaft of the rotary drive component is connected to the drive gear. When the rotary drive component drives the drive gear to rotate, based on the meshing of the drive gear and the rack 23, the lifting seat 111 can be driven to move along the guide rail 2 via the drive gear.

[0079] To facilitate control of the lifting body 11 to hover at any position relative to the guide rail 2, the drive mechanism 112 may also be equipped with an electromagnetic brake. When it is necessary to control the lifting seat 111 to stop running, the electromagnetic brake can be de-energized so that the electromagnetic brake and the output shaft of the rotary drive are connected. Based on the braking of the output shaft of the rotary drive by the electromagnetic brake, the drive gear can be prevented from rolling relative to the rack 23, thereby ensuring that the lifting seat 111 is hovered on the guide rail 2.

[0080] Meanwhile, during the normal lifting and lowering of the lifting platform 111 along the guide rail 2, the fall arrestor 113 can restrain the lifting platform 111 on the guide rail 2 in the event of a stall and fall, ensuring the safe operation of the lifting platform 111. The fall arrestor 113 includes a speed limiter and a fall arrestor gear. The output shaft of the speed limiter is connected to the fall arrestor gear. The speed limiter can be a fall arrestor speed limiting device known in the art, such as a speed limiter including a centrifugal speed limiting mechanism, a braking mechanism, a loading mechanism, and a speed limit switch. The braking mechanism and the loading mechanism are respectively connected to the centrifugal speed limiting mechanism, which is coaxially connected to the fall arrestor gear via a drive shaft.

[0081] During the lifting and lowering operation of the lifting platform 111, the anti-fall gear drives the centrifugal speed limiting mechanism to rotate, enabling the centrifugal speed limiting mechanism to detect the operating speed of the lifting platform 111. When the lifting platform 111 stalls and descends, that is, when the centrifugal speed limiting mechanism detects that the operating speed of the lifting platform 111 is greater than a preset value, the centrifugal block in the centrifugal speed limiting mechanism opens and drives the braking mechanism to rotate, generating braking force. During the braking process, the braking mechanism is subjected to the action of the loading mechanism, causing the braking force to gradually increase until the anti-fall gear stops rotating.

[0082] It should be noted here that, as Figure 2 As shown, the lifting body 11 also includes a control box 114, which is mounted on the lifting base 111 and is communicatively connected to the drive mechanism 112 and the fall arrestor 113. Along the height direction of the lifting base 111, the drive mechanism 112 is located above the fall arrestor 113, and the control box 114 can be positioned between the drive mechanism 112 and the fall arrestor 113. The control box 114 contains a control module such as a microcontroller or PLC controller, which is communicatively connected to the drive mechanism 112, the fall arrestor 113, and various sensors (such as position detection devices, weighing sensors, and various switches in the following embodiments).

[0083] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the lifting seat 111 is also provided with a guide wheel assembly 1111, which is clamped on both sides of the guide rail 2 to roll along the extension direction of the guide rail 2.

[0084] Understandably, the guide wheel assembly 1111 applies a horizontal constraint to the guide rail 2 to prevent the lifting seat 111 from tipping over. While ensuring that the entire lifting device 1 moves smoothly up and down along the guide rail 2, it also provides a holding force for the meshing between the drive gear and the rack 23, as well as the meshing between the anti-fall gear and the rack 23.

[0085] In practical applications, the guide rail 2 has two guide rail structures 21 arranged side by side. For example, the guide rail structure 21 is a column located on the left and right sides of the guide rail 2. Multiple guide wheel groups 1111 are provided. A part of the multiple guide wheel groups 1111 is clamped on the guide rail structure 21 located on the left side, and another part of the multiple guide wheel groups 1111 is clamped on the guide rail structure 21 located on the right side. Under the guidance of the multiple guide wheel groups 1111, the lifting device 1 is ensured to rise and fall stably and reliably along the extension direction of the guide rail 2.

[0086] In some embodiments, such as Figure 2 and Figure 6 As shown, the lifting seat 111 is also equipped with an anti-disengagement hook 1112, which surrounds the guide rail 2 on the side away from the lifting seat 111.

[0087] Understandably, during the normal lifting and lowering process of the lifting seat 111 along the guide rail 2, the anti-disengagement hook 1112 does not contact the guide rail 2. However, when the guide wheel assembly 1111 fails and causes the lifting seat 111 to shift laterally relative to the guide rail 2, the anti-disengagement hook 1112 abuts against the side of the guide rail 2 away from the lifting seat 111 to prevent the lifting seat 111 from shifting laterally relative to the guide rail 2. This ensures that the drive gear and the anti-fall gear can maintain meshing with the rack 23, thereby ensuring the safety of the lifting equipment 1 during lifting and lowering operations.

[0088] In the case where the guide rail 2 has two guide rail structures 21 arranged side by side, there are two anti-disengagement hooks 1112, and the two anti-disengagement hooks 1112 are arranged one-to-one with the two guide rail structures 21.

[0089] In the second aspect, such as Figure 1 , Figure 12 and Figure 14 As shown, the present invention also provides a lifting and rotating transport platform, including a guide rail 2, a transport platform 3, and a lifting device 1 as described above; the guide rail 2 is used to install on the current construction surface of the overlapping structure; the lifting device 1 moves up and down along the guide rail 2; the transport platform 3 is hung on the mounting frame 12, and when the lifting device 1 moves to the target working layer, the transport platform 3 is rotated to the target construction surface under the drive of the mounting frame 12 to connect with the target position of the target working layer; wherein, the current construction surface and the target construction surface are located at two different lateral positions of the overlapping structure.

[0090] It is understandable that the guide rail 2 is connected to the overlapping structure through the connecting accessory 8, so that the layout position of the guide rail 2 relative to the overlapping structure can be adjusted according to actual needs; the overlapping structure can be a scaffolding structure, or a building structure, bridge structure, tunnel, etc., without specific limitations.

[0091] Based on the setup of the lifting device 1, when the lifting device 1 is operating at the current construction surface, it can carry the transport platform 3 to the target working level. Then, the mounting frame 12 of the lifting device 1 can drive the transport platform 3 to rotate to the target construction surface, which facilitates the transfer of personnel or materials carried by the transport platform 3 to the target construction surface. This design meets the needs of personnel / material transfer at different construction surfaces and makes it easier for workers to flexibly carry out construction operations at different construction surfaces.

[0092] Since the lifting and rotating transport platform includes a lifting device 1, and the specific structure of the lifting device 1 is as described in the above embodiments, the lifting and rotating transport platform of this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the advantages obtained by all the technical solutions of the above embodiments, which will not be described in detail here.

[0093] In some embodiments, such as Figure 8 , Figure 9 and Figure 10 As shown, the transport platform 3 includes a movable frame 31 and a flip door 32; the movable frame 31 is basket-shaped and is attached to one side of the mounting frame 12, and a receiving space 311 is formed inside the movable frame 31, and a passage 312 communicating with the receiving space 311 is formed on one side of the movable frame 31; the flip door 32 is rotatably disposed on the movable frame 31 and can switch between a vertical state and a horizontal state; when the flip door 32 is in the vertical state, the flip door 32 is used to cover at least part of the passage 312; when the flip door 32 is in the horizontal state, the flip door 32 is used to dock with the target working layer.

[0094] It is understandable that the storage space 311 inside the movable frame 31 is used to carry workers. Of course, if the storage requirements are met, the movable frame 31 can also carry building materials, which enables the entire transport platform 3 to meet the needs of carrying people and goods.

[0095] In practical applications, the bottom of the movable frame 31 is equipped with wheels, such as directional wheels and omnidirectional wheels. Based on the design of the wheels, it can be ensured that the transport platform 3 can move on the ground to reach the actual unloading position.

[0096] Meanwhile, when the lifting device 1 is moving up and down on the current construction surface, the movable frame 31 is attached to one side of the mounting frame 12, and the flip door 32 is in a vertical position to block at least part of the passageway 312. When the transport platform 3 is flipped to the target construction surface by the mounting frame 12, the flip door 32 is in a horizontal position so that the workers can reach the target working level based on the horizontally distributed flip door 32, and it is also convenient to transfer the materials loaded in the movable frame 31 to the target working level.

[0097] It should be noted that when the transport platform 3 is placed on a horizontal ground, or when the transport platform 3 is attached to the mounting frame 12 and the entire lifting equipment is in the starting position, switching the flip door 32 to a horizontal state also facilitates the transfer of personnel or materials to the movable frame 31.

[0098] In some embodiments, such as Figure 9 and Figure 10 As shown, the transport platform 3 also includes a passenger guardrail 33, which is detachably mounted on the movable frame 31. The flip door 32 is used to cover the lower part of the passage 312, and the passenger guardrail 33 is used to protect the upper part of the passage 312.

[0099] Understandably, the protective barrier 33 on the upper side of the passage 312 can ensure the safety of the transport platform 3 when carrying people up and down.

[0100] In practical applications, the personnel guardrail 33 can be a railing. One end of the railing is rotatably connected to the top of one side of the passage 312 via a pin. When the worker enters the accommodating space 311 from the passage 312, the railing can be manually flipped to open the passage 312. After the worker enters the accommodating space 311, the railing can be manually flipped again, for example, to a horizontal position to protect the upper part of the passage 312.

[0101] In some embodiments, such as Figure 8 As shown, the transport platform 3 also includes a cargo rack 34, which is detachably mounted on the upper side of the movable frame 31.

[0102] It is understandable that the shelf 34 is used to carry materials. For example, the top of the shelf 34 has a bearing surface, and the bearing surface is provided with multiple locking parts, which can be used to fix the materials carried on the bearing surface.

[0103] In practical applications, if it is necessary to transport materials, the personnel guardrail 33 can be removed from the movable frame 31, and the cargo rack 34 can be installed on the upper side of the movable frame 31. The operation is simple and convenient, enabling the entire transport platform 3 to support both cargo and personnel functions. It can switch configurations according to construction needs, has strong versatility, and helps reduce construction costs.

[0104] The materials shown in this embodiment can be not only various building materials, various decoration materials and photovoltaic panels, but also long and wide materials such as wooden boards and plywood that are inconvenient to move in the corridor. There is no specific limitation on this.

[0105] like Figure 8As shown, the bottom of the shelf 34 and the top of the movable frame 31 can be plugged in to quickly install the shelf 34 onto the upper side of the movable frame 31. For example, the bottom of the shelf 34 has multiple insertion interfaces, and the top of the movable frame 31 has multiple plug connectors, which are inserted into the multiple insertion interfaces one by one.

[0106] In some embodiments, such as Figure 9 , Figure 10 and Figure 11 As shown, the transport platform 3 also includes a detection component 35, which is communicatively connected to the lifting device 1. The detection component 35 is used to detect whether one side of the mounting frame 12 is attached to the transport platform 3, and to detect whether the flip door 32 on the transport platform 3 is in the state of closed passage 312.

[0107] Specifically, the detection component 35 includes a photoelectric sensor, a connecting arm 351, and a second elastic element 354; wherein, the photoelectric sensor is in Figures 9 to 11 Not shown in the diagram. A photoelectric sensor is mounted on the mounting frame 12 and is used to communicate with the lifting device 1. A connecting arm 351 is rotatably mounted on the side of the movable frame 31 facing the mounting frame 12. The first end of the connecting arm 351 is provided with a pressure roller 352, and the second end of the connecting arm 351 is provided with a trigger plate 353. The second elastic element 354 can be a spring and is connected between the connecting arm 351 and the movable frame 31. The pressure roller 352 is located on one side of the passage 312 and is used to drive the connecting arm 351 to swing under the pressure of the flip door 32, so that the trigger plate 353 triggers the photoelectric sensor.

[0108] It is understood that a hinge end is formed on one side of the first end of the connecting arm 351. The connecting arm 351 is rotatably connected to the movable frame 31 through the hinge end. A guide structure is provided between the connecting arm 351 and the movable frame 31. The guide structure is used for the connecting arm 351 to swing around the axis where the hinge end is located.

[0109] For example, the guide structure includes a guide pin and a guide groove. The guide groove is disposed on the side of the movable frame 31 and extends circumferentially along the axis where the hinge end is located. The guide pin is disposed on the linkage arm 351, one end of the guide pin extends into the guide groove and is slidable along the extension direction of the guide groove.

[0110] Since the photoelectric sensor is mounted on the mounting frame 12, when the transport platform 3 is not attached to one side of the mounting frame 12, the photoelectric sensor will not be triggered by the trigger plate 353. At this time, the lifting equipment 1 will not start running under the trigger of the photoelectric sensor.

[0111] When the transport platform 3 is attached to one side of the mounting frame 12, if the flip door 32 is not closed to the passage 312, for example, when the flip door 32 is in a horizontal state, the linkage arm 351 is in a first swing posture under the abutment of the second elastic member 354. At this time, the photoelectric sensor and the trigger plate 353 are misaligned, that is, the photoelectric sensor will not be triggered by the trigger plate 353. At this time, the lifting device 1 will not start running under the trigger of the photoelectric sensor.

[0112] When the flip door 32 closes the passage 312, for example, when the flip door 32 is in a vertical state, the flip door 32 will press the pressure wheel 352 so that the connecting arm 351 overcomes the elastic swing of the second elastic element 354 to the second swing posture. At this time, the photoelectric sensor and the trigger plate 353 are aligned, that is, the photoelectric sensor will be triggered by the trigger plate 353. At this time, the lifting device 1 can start running under the trigger of the photoelectric sensor.

[0113] In some embodiments, such as Figure 1 As shown, the guide rail 2 has a guide rail structure 21, a ladder structure 22 and a rack 23 along its extension direction.

[0114] It is understandable that the guide rail 2 is made of high-strength wear-resistant material, such as steel structure, to provide guidance and support for the lifting of the lifting device 1.

[0115] The guide rail structure 21 is used to guide the lifting body 11 to move up and down. The ladder structure 22 is used for workers to climb and can also serve as an emergency passage in case of emergency. The rack 23 is used to mesh with the drive gear of the drive mechanism 112 to transmit power for the lifting of the entire lifting body 11.

[0116] In practical applications, the guide rail 2 includes a rack 23, two columns and multiple foot rods. The two columns are arranged side by side, and the multiple foot rods are arranged side by side between the two columns along the extension direction of the columns. The rack 23 is arranged on the side of one of the columns along the extension direction of the columns. Both columns serve as guide rail structures 21, and the multiple foot rods form a ladder structure 22.

[0117] In some embodiments, such as Figure 1 As shown, the guide rail 2 includes multiple segments, which are connected in sequence, and at least one segment is connected to the overlapping structure.

[0118] In practical applications, except for the bottommost segment, all other segments can be used as standard segments. At least one segment can be quickly connected to the scaffolding or other overlapping structures on the construction site via connector 8 to improve the stability and convenience of equipment docking and operation.

[0119] like Figure 3As shown, both the bottommost and topmost segments are connected to the scaffolding or other lap structures on the construction site via connecting attachment 8; the bottom of the bottommost segment can also be connected via... Figure 1 The mounting bracket 10 shown is fixed to the ground foundation to ensure stable operation of the equipment.

[0120] In practical applications, the following can be adopted: Figure 15 The mobile trolley 9 shown moves the lifting equipment 1 to the installation position. The bottom end of the lowest segment is fixed to the ground foundation using the fixing frame 10. The lifting equipment 1 is unloaded from the mobile trolley 9 and installed on one side of the lowest segment. Then, the installation of the other segments of the guide rail 2 is completed from bottom to top, ensuring that at least one segment is connected to the scaffolding or other overlapping structure on the construction site through the connecting attachment 8.

[0121] Meanwhile, the lifting and rotating transport platform shown in this embodiment is also equipped with a cable management component 4. The cable management component 4 is used to organize the cables (such as power cables and control cables) of the lifting equipment 1, so as to prevent the cables from becoming tangled during the lifting process of the lifting equipment 1, and also to prevent the cables from swaying in the wind. The upper end of the cable is electrically connected to the control box 114 of the lifting equipment 1, and the lower end of the cable is electrically connected to the mains power supply.

[0122] For example, such as Figure 12 and Figure 13 As shown, the cable management assembly 4 includes at least a cable hanger 401 and a flexible cable management base 402. The cable hanger 401 is located on one side of the lifting device 1, for example, the cable hanger 401 is located on one side of the lifting base 111. The cable hanger 401 is provided with a cable hole for threading cables.

[0123] Meanwhile, the flexible cable management seat 402 is used to be installed on the scaffolding on one side of the lifting equipment 1; the flexible cable management seat 402 includes a connecting arm and a flexible seat body; the connecting arm is used to connect with the scaffolding; along the vertical direction, the projection of the flexible seat body and the projection of the cable hanger 401 have an overlapping area; the flexible seat body includes a first flexible arm and a second flexible arm, the first end of the first flexible arm and the first end of the second flexible arm are arranged side by side on the connecting arm, the second end of the first flexible arm and the second end of the second flexible arm are arranged opposite to each other, and a cable management channel is formed between the first flexible arm, the second flexible arm and the connecting arm.

[0124] In practical applications, when the lifting device 1 is raised or lowered, the cable hanger 401 carries the cable and moves relative to the flexible seat. Under the compression of the cable hanger 401, the second ends of the first flexible arm and the second flexible arm move away from each other to ensure that the cable hanger 401 can pass between the first flexible arm and the second flexible arm. After the cable hanger 401 passes between the first flexible arm and the second flexible arm, the second ends of the first flexible arm and the second flexible arm come into contact with each other to confine the cable carried by the cable hanger 401 in the cable management channel.

[0125] Furthermore, such as Figure 12 and Figure 13 As shown, the cable management assembly 4 also includes a cable reel 403 and a junction box 404. The cable reel 403 is set on the ground foundation. The lower end of the cable is wound around the perimeter of the cable reel 403 and electrically connected to the junction box 404 set on one side of the cable reel 403. The junction box 404 is used to electrically connect to the mains power supply.

[0126] In some embodiments, such as Figure 4 and Figure 6 As shown, the lifting device 1 is provided with an upper limit switch K1 on the side facing the guide rail 2, and an upper limit plate X1 for triggering the upper limit switch K1 is provided on the top of the guide rail 2; the upper limit switch K1 is communicatively connected to the control box 114 of the lifting body 11; when the upper limit switch K1 is triggered by the upper limit plate X1, the lifting body 11 stops running according to the trigger signal of the upper limit switch K1.

[0127] like Figure 4 As shown, a buffer 201 is also provided at the top of the guide rail 2. The buffer 201 is set at a height higher than the upper limit plate X1. The buffer 201 is used to physically block the lifting body 11 from continuing to move upward when the upper limit switch K1 fails to limit it.

[0128] In some embodiments, such as Figure 4 and Figure 6 As shown, a lower limit switch K2 is provided on the side of the lifting device 1 facing the guide rail 2, and a lower limit plate X2 for triggering the lower limit switch K2 is provided at the bottom of the guide rail 2; the lower limit switch K2 is communicatively connected to the control box 114 of the lifting body 11; when the lower limit switch K2 is triggered by the lower limit plate X2, the lifting body 11 stops running according to the trigger signal of the lower limit switch K2.

[0129] In some embodiments, such as Figure 4 and Figure 6As shown, a platform replacement trigger switch K3 is provided on the side of the lifting device 1 facing the guide rail 2, and a platform replacement trigger plate X3 is provided at the bottom of the guide rail 2 to trigger the platform replacement trigger switch K3; and a lower limit switch K4 is provided on the side of the lifting device 1 facing the guide rail 2, and a lower limit trigger plate X4 is provided at the bottom of the guide rail 2 to trigger the lower limit switch K4; the platform replacement trigger switch K3 and the lower limit switch K4 are respectively connected to the control box 114 of the lifting body 11; when the platform replacement trigger switch K3 is triggered by the platform replacement trigger plate X3, the lifting body 11 stops running according to the trigger signal of the platform replacement trigger switch K3. At this time, the bottom of the transport platform 3 is in contact with the ground, and the user needs to manually send control commands to the lifting body 11 using a remote control or other host computer, and the lifting body 11 will continue to descend. When the lower limit switch K4 is triggered by the lower limit trigger plate X4, the lifting body 11 stops at the lower limit position according to the trigger signal of the lower limit switch K4, so as to separate the transport platform 3 from the mounting frame 12.

[0130] In some embodiments, such as Figure 4 and Figure 6 As shown, a platform limit trigger switch K5 is provided on the side of the lifting device 1 facing the guide rail 2, and a platform limit trigger plate X5 is provided on the guide rail 2 to trigger the platform limit trigger switch K5; the platform limit trigger switch K5 is communicatively connected to the control box 114 of the lifting body 11; when the platform limit trigger switch K5 is triggered by the platform limit trigger plate X5, the lifting body 11 stops at the target working layer corresponding to the platform limit trigger plate X5 according to the trigger signal of the platform limit trigger switch K5; or, according to the trigger signal of the platform limit trigger switch K5, when the lifting body 11 crosses the target working layer, the indicator light on the lifting body 11 will flash.

[0131] In some embodiments, such as Figure 6 As shown, an anti-overtravel electromagnetic switch K6 is also installed on the top of the lifting body 11. The anti-overtravel electromagnetic switch K6 is communicatively connected to the control box 114 of the lifting body 11. The anti-overtravel electromagnetic switch K6 is positioned towards the rack 23 of the guide rail 2. When the anti-overtravel electromagnetic switch K6 detects that there is no rack 23 in front of the lifting body 11, the lifting body 11 stops running to ensure the safe operation of the entire lifting device 1.

[0132] In some embodiments, such as Figure 12 , Figure 13 and Figure 14 As shown, the lifting and rotating transport platform also includes a transfer platform 5 and a door 6; the transfer platform 5 is located on the target working level and is positioned at the target location where it docks with the horizontally positioned flip door 32; the door 6 is located on one side of the transfer platform 5 to control the flow of personnel between the transfer platform 5 and the target working level.

[0133] It is understandable that the transfer platform 5 serves as a platform for connecting the construction facilities of the target working layer with the transport platform 3, in order to ensure the safety of the workers; among them, a platform guardrail is installed along the circumference of the transfer platform 5.

[0134] Meanwhile, the switch door 6 can be a sliding door or a double door, without specific limitations; the switch door 6 is configured to be opened only from the side where the transfer station 5 is located, to avoid safety risks caused by workers on the target working floor accidentally opening the switch door 6.

[0135] like Figure 12 and Figure 13 As shown, when the lifting device 1 is in the starting position or when the lifting device 1 is moving up and down along the guide rail 2, the door 6 is in the closed state; Figure 14 As shown, when the lifting equipment 1 carrying the transport platform 3 arrives at the target working level, the mounting frame 12 of the lifting equipment 1 drives the transport platform 3 to rotate to the target construction surface that connects with the transfer platform 5. The rotating door 32 of the transport platform 3 is in a horizontal state, and the personnel guardrail 33 on the transport platform 3 rotates upward to open the passage 312. At this time, the personnel in the transport platform 3 can walk through the rotating door 32 to the transfer platform 5, and then open the switch door 6 to reach the working position where the target working level is located.

[0136] In one application scenario, the lifting and rotating transport platform shown in this invention is used in the transfer of construction materials for high-rise buildings.

[0137] In this embodiment, the lifting and rotating transport platform is installed on the scaffolding of a high-rise building or other exterior construction areas to transfer construction materials from the ground to the target working level. Its workflow is as follows: (1) Starting position: The lifting equipment is at the lowest position on the ground, the transport platform is configured in the cargo carrying mode, the transport platform is equipped with a cargo rack, and the guide rail is connected to the scaffolding through connecting accessories; (2) Material loading: Load the construction materials onto the frame, and fix the construction materials on the frame with a locking structure; (3) Vertical lifting: Control the start and operation of the lifting equipment. The lifting equipment carries the transport platform and rises vertically along the guide rail until it reaches the target working layer; (4) Rotation docking: After the lifting equipment reaches the target working layer, the control of the mounting frame drives the transport platform to rotate relative to the lifting body around the vertical axis to adjust to the docking position with the transfer platform where the target working layer is located, and the mounting frame is locked. (5) Material unloading: Unload the construction materials in the transport platform to the target working layer; (6) Return trip: The mounting frame drives the transport platform to rotate and reset, and the entire lifting equipment descends back to the starting position on the ground, completing the transfer of construction materials.

[0138] In another application scenario, the lifting and rotating transport platform shown in this invention is used for the up-and-down operation of construction workers in high-rise buildings. In this embodiment, the lifting and rotating transport platform is installed on the scaffolding of a high-rise building or other exterior construction areas to transport construction workers from the ground to the target working level, and then rotates them to the target construction surface where the target working level is located. Its workflow is as follows: (1) Starting position: The lifting equipment is at the lowest position on the ground, the transport platform is configured in the manned mode, the transport platform is equipped with manned guardrails, and the guide rail is connected to the scaffolding through connecting accessories; (2) Personnel boarding: The flip door of the transport platform is in a horizontal state. After the construction personnel enter the storage space of the transport platform through the passage, the flip door is in a vertical state to cover the lower part of the passage. The personnel guardrail protects the upper part of the passage. (3) Vertical lifting: Control the start and operation of the lifting equipment. The lifting equipment carries the transport platform and rises vertically along the guide rail until it reaches the target working layer; (4) Rotation docking: After the lifting equipment reaches the target working layer, the control frame drives the transport platform to rotate relative to the lifting body around the vertical axis to adjust to the docking position with the transfer platform where the target working layer is located. The rotating door of the transport platform is switched to the horizontal state, and the switch door on one side of the transfer platform is opened. (5) Personnel getting on and off: Construction personnel enter the target working layer from the transport platform, or construction personnel return from the target working layer to the transport platform; (6) Return trip: Close the switch door on one side of the transfer platform, switch the flip door of the transport platform to the vertical state, the hanging frame drives the transport platform to rotate and reset, and the entire lifting equipment descends back to the starting position on the ground to complete the transfer operation of construction personnel.

[0139] In summary, based on the solutions described in the above embodiments, the present invention has the following beneficial effects: (1) High operational flexibility: Through the coordinated design of vertical lifting and horizontal rotation, the entire transport platform can adapt to the operational needs of different construction surfaces. There is no need to repeatedly install multiple pieces of equipment, which not only reduces construction costs but also significantly improves construction efficiency.

[0140] (2) High versatility: It supports rapid switching between cargo and personnel configurations, which can meet the dual needs of material transfer and personnel loading and unloading, reduce equipment investment costs, realize dual use of one machine, increase equipment utilization rate by more than 50%, and reduce the number of equipment purchased and site occupation.

[0141] (3) Good docking stability: By designing connecting accessories that are compatible with scaffolding and combining the flipping and adjustment function of the transport platform itself, seamless docking with construction facilities can be achieved, ensuring the continuity of the construction process.

[0142] (4) High security: The multi-dimensional safety interlock design realizes comprehensive monitoring of all safety links, eliminates safety accidents caused by misoperation from the hardware level, and the safety protection level reaches an extremely high level.

[0143] (5) Modular structure: Each component adopts a modular design, and all components can be disassembled for transportation. The maximum weight of a single component does not exceed 100kg.
