Description

Technical Field

[0001] This disclosure relates to the field of photovoltaic equipment technology, and more specifically to a trolley mechanism for photovoltaic installation equipment. Background Technology

[0002] Photovoltaic power generation has advantages such as being clean, renewable, and environmentally friendly, and is widely used in open areas such as deserts. Because individual photovoltaic panels are heavy and bulky, they are difficult to move manually, so specialized photovoltaic installation equipment is needed to hoist them into place.

[0003] Traditional photovoltaic (PV) installation equipment uses a trolley to lift PV panels. These trolleys are generally large in size and weight, requiring the supporting structure to be equally large and heavy. This results in existing PV installation equipment being bulky, heavy, and cumbersome. Utility Model Content

[0004] The technical problem solved by this disclosure is to provide an improved trolley mechanism for photovoltaic installation equipment.

[0005] To address the aforementioned technical problems, this disclosure provides a trolley mechanism for photovoltaic installation equipment. The photovoltaic installation equipment includes a main body, and the trolley mechanism includes: a trolley movably mounted on the main body, the trolley being used to lift photovoltaic modules using a lifting device; and a trolley moving mechanism including a drive device and a transmission mechanism, the transmission mechanism connecting the drive device and the trolley, the drive device controlling the trolley to reciprocate relative to the main body in a first direction via the transmission mechanism; wherein the drive device is disposed on the photovoltaic installation equipment and is independently disposed outside the trolley.

[0006] Optionally, the main body includes a transverse support and a vertical support for supporting the transverse support, and the trolley is movably mounted on the transverse support; the drive device is mounted on the side of the transverse support near the vertical support, or mounted on the vertical support.

[0007] Optionally, the bottom of the vertical support has an installation platform, and the driving device is disposed on the installation platform.

[0008] Optionally, along the first direction, the drive device and the trolley are located on opposite sides of the center of gravity of the main body.

[0009] Optionally, the trolley has a first end and a second end opposite to each other along the first direction, and the transmission mechanism includes a traction rope, the traction rope including: a first section connecting the drive device and the first end; and a second section connecting the drive device and the second end; wherein the first section and the second section each include at least one section extending along the first direction, and the drive device is used to drive the first section and the second section respectively to drive the trolley to move back and forth along the first direction.

[0010] Optionally, the drive device includes a first spool and a second spool that are independent of each other. The first spool is connected to the first section to adjust the extension length of the first section, and the second spool is connected to the second section to adjust the extension length of the second section.

[0011] Optionally, the drive device further includes a power unit for driving the first drum and the second drum.

[0012] Optionally, the first drum and the second drum are located on the same side of the trolley, the same side being the side closer to the first end; a first pulley group is provided on the main body, one end of the second section is connected to the second end of the trolley, and the other end is connected to the second drum after being turned by the first pulley group.

[0013] Optionally, the drive device is not located on the movement path of the trolley reciprocating along the first direction or on its extension line. A second pulley group is provided on the main body. One end of the first section and the second section are respectively connected to the trolley, and the other end is respectively connected to the drive device after being turned by the second pulley group.

[0014] Optionally, the trolley includes multiple independent trolley modules, which are spaced apart and connected to the main body along a second direction; the trolley mechanism also includes multiple trolley moving mechanisms, which correspond one-to-one with the multiple trolley modules, and drive the multiple trolley modules to move synchronously along a first direction; wherein the vertical direction, the first direction, and the second direction are perpendicular to each other.

[0015] Compared with the prior art, the technical solutions of the embodiments of this disclosure have the following beneficial effects:

[0016] The trolley mechanism disclosed herein is equivalent to the existing lifting trolley mechanism. Compared to the integrated design of the existing lifting trolley mechanism, the present disclosure divides the trolley mechanism into two functional parts. One part is a trolley for connecting the main body and the lifting device, and the other part is a trolley moving mechanism for realizing the movement of the trolley. The trolley moving mechanism further includes a drive device and a transmission mechanism. With the transmission mechanism realizing power transmission, the drive device can be set independently of the trolley, thereby simplifying the structure of the trolley connected to the main body, significantly reducing the weight of the trolley, and reducing the overall cost. Thus, the trolley mechanism is broken down into parts, and the layout of each part is more flexible.

[0017] In existing technologies, all drive components are integrated onto the trolley, resulting in a complex structure and heavy overall weight. Consequently, the main body supporting the trolley must also be enlarged in size or weight to stably support it and ensure its normal operation, thus increasing the overall weight and cost of existing photovoltaic installation equipment. In contrast, this application moves the drive unit from the trolley to other locations on the photovoltaic installation equipment, reducing both the weight and size of the trolley. This allows the main body to use a smaller structure and lighter weight while still stably supporting the trolley, achieving overall weight reduction and cost reduction.

[0018] Furthermore, the lighter trolley also helps improve the structural stability of photovoltaic installation equipment. For example, in scenarios where the main body adopts a cantilever beam structure, even if the lighter trolley moves the lifting equipment and photovoltaic modules to the end of the horizontal support that is far from the vertical support, it can still ensure that the center of gravity of the entire machine remains near the vertical support. This greatly reduces the probability of overturning due to the center of gravity of the main body deviating, and improves the stability of the entire machine. Furthermore, placing the drive unit as close as possible to the vertical support can more reliably mitigate the center of gravity shift of the main body and improve the stability of the entire machine.

[0021] Figure 3 This is a schematic diagram of the trolley mechanism in a variation of an embodiment of this disclosure. Detailed Implementation

[0022] As mentioned in the background section, existing photovoltaic installation equipment suffers from the drawback of a heavy trolley for the mounting bracket, which increases the overall cost and affects the stability of the entire system.

[0023] The inventors of this application, through analysis, discovered that one of the reasons for the aforementioned technical problems is that the trolley needs to move under the drive of a drive unit, and in existing photovoltaic installation equipment, the drive unit is generally integrated onto the trolley. That is, when the photovoltaic installation equipment is working, the drive unit and the trolley move as a single unit on the main vehicle. This results in a very large overall weight for the trolley, and integrating the drive unit onto the trolley inevitably increases the structural complexity of the trolley. Furthermore, the weight of the drive unit directly acts on the cantilever beam, undoubtedly increasing the burden on the cantilever beam and affecting the overall stability of the machine.

[0024] To address the aforementioned technical problems, this disclosure provides a trolley mechanism for photovoltaic installation equipment. The photovoltaic installation equipment includes a main body, and the trolley mechanism includes: a trolley movably mounted on the main body, the trolley being used to lift photovoltaic modules using a lifting device; and a trolley moving mechanism including a drive device and a transmission mechanism, the transmission mechanism connecting the drive device and the trolley, the drive device controlling the trolley to reciprocate relative to the main body in a first direction via the transmission mechanism; wherein the drive device is disposed on the photovoltaic installation equipment and is independently disposed outside the trolley.

[0025] By functionally dividing the trolley mechanism into two parts—one connecting the main body and the lifting device, and the other a trolley moving mechanism that enables trolley movement—the trolley moving mechanism includes a drive unit and a transmission mechanism. With the transmission mechanism transmitting power, the drive unit can be installed independently of the trolley, simplifying the structure of the trolley connected to the main body, significantly reducing its weight, and lowering the overall cost. Thus, the trolley mechanism is modularized, allowing for more flexible placement of each part. Furthermore, the trolley's reduced weight and size allow the main body to use a smaller structure and lighter weight while still stably supporting the trolley, achieving overall weight reduction and cost reduction.

[0026] To make the above-mentioned objectives, features and beneficial effects of this disclosure more apparent and understandable, specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0027] Figure 1 This is a schematic diagram of a photovoltaic installation device 100 according to an embodiment of the present disclosure. Figure 2 yes Figure 1 A schematic diagram of the small and medium-sized vehicle mechanism 1.

[0028] This implementation scheme can be applied to the field of photovoltaic module installation technology, where photovoltaic modules are installed in designated locations using photovoltaic installation equipment 100. A photovoltaic module can be a single photovoltaic panel or multiple photovoltaic panels pre-assembled into a single unit.

[0029] Specifically, refer to Figure 1 and Figure 2The photovoltaic installation equipment 100 may include a main body 2, a trolley mechanism 1, and a lifting device (not shown). The main body 2 is used to provide a support frame, and specifically may include a horizontal support 21 and a vertical support 22 for supporting the horizontal support 21. For ease of description, in this embodiment, the extension direction of the vertical support 22 is referred to as the z-direction (also called the vertical direction), the extension direction of the horizontal support 21 is referred to as the x-direction (also called the first direction), and the direction perpendicular to both the x-direction and the z-direction is referred to as the y-direction (also called the second direction).

[0030] Furthermore, the bottom of the vertical support 22 has an installation platform 23. The vertical support 22, the horizontal support 21, the trolley mechanism 1, and the lifting device are all directly or indirectly supported on the installation platform 23. The bottom of the installation platform 23 may be equipped with a traveling mechanism 24 such as tracks to drive the entire photovoltaic installation equipment 100 to move.

[0031] Furthermore, the lifting device is connected to the main body 2 via a trolley mechanism 1. The lifting device is used to lift the photovoltaic modules. The trolley mechanism 1 specifically includes a trolley 11 and a trolley moving mechanism 12. The figure mainly shows the frame structure of the trolley 11, also called the trolley frame, omitting other components of the trolley 11, such as the micro-motion mechanism on the trolley. The trolley 11 is movably mounted on the main body 2. For example, the trolley 11 is mounted on the transverse support 21 and can move in the x-direction or its opposite direction, with the lifting device connected below the trolley 11 in the z-direction. The trolley moving mechanism 12 is used to realize the relative movement between the trolley 11 and the main body 2. For example, the trolley moving mechanism 12 is used to control the trolley 11 to reciprocate in the x-direction relative to the transverse support 21. By controlling the movement of the trolley 11 relative to the transverse support 21 in the x-direction, the lifting device and the photovoltaic modules lifted by the lifting device can be moved to the designated installation position.

[0032] Furthermore, the trolley moving mechanism 12 includes a drive unit 121 and a transmission mechanism 122. The drive unit is disposed on the photovoltaic installation equipment 100, and is disposed independently of the trolley 11. In other words, the drive unit is installed in a position on the photovoltaic installation equipment 100 other than the trolley. The transmission mechanism 122 connects the drive unit 121 and the trolley 11, and the drive unit 121 controls the trolley 11 to reciprocate relative to the main body 2 in the x-direction via the transmission mechanism 122.

[0033] For example, a trolley 11 is movably mounted on a transverse support 21, a drive unit 121 is mounted on an installation platform 23, and a transmission mechanism 122 is arranged along the main body 2 to mechanically connect the trolley 11 and the drive unit 121. In a typical application scenario, after the main body 2 moves to the area where the photovoltaic module needs to be installed, driven by the traveling mechanism 24, the lifting device lifts the photovoltaic module to be installed. At this time, the real-time position of the photovoltaic module and its target position within the installation area may be offset in the z-direction. The drive unit 121 is then controlled to operate based on the positional deviation between the real-time and target positions of the photovoltaic module, so that the trolley 11 is moved along the x-direction or its opposite direction via the transmission mechanism 122 until the real-time and target positions of the photovoltaic module are aligned in the z-direction. Then, the lifting device is lowered to place the photovoltaic module in the target position, completing the installation of the photovoltaic module.

[0034] Based on the above, the trolley mechanism 1 is functionally divided into two parts. One part is the trolley 11 used to connect the main body 2 and the lifting device, and the other part is the trolley moving mechanism 12 that realizes the movement of the trolley 11. The trolley moving mechanism 12 includes a drive device 121 and a transmission mechanism 122. With the transmission mechanism 122 realizing power transmission, the drive device 121 can be set independently of the trolley 11, thereby simplifying the structure of the trolley 11 connected to the main body 2, significantly reducing the weight of the trolley 11, and reducing the overall cost. Thus, the trolley mechanism 1 is broken down into parts, and the layout of each part is more flexible.

[0035] Furthermore, by moving the drive unit 121 from the trolley 11 to other locations on the photovoltaic installation equipment 100, the weight and volume of the trolley 11 are reduced. Correspondingly, the main body 2 adopts a smaller structure and lighter weight, which can stably support the trolley 11, thereby reducing the overall weight and cost.

[0036] Furthermore, for both ends of the transverse support 21 along the x-direction, one end is positioned closer to the vertical support 22 than the other. That is, the main body 2 as a whole forms a cantilever beam structure. Therefore, the lighter trolley 11 in this embodiment also helps improve the structural stability of the photovoltaic installation equipment 100. Specifically, even if the lighter trolley 11 moves the lifting device and photovoltaic modules to the end of the transverse support 21 away from the vertical support 22, it can still ensure that the center of gravity of the entire machine remains near the vertical support 22. This greatly reduces the probability of the main body 2 tilting due to a deviation in its center of gravity, thus improving the overall stability of the machine.

[0037] In one variation, the drive unit 121 can be mounted on the vertical support 22. For example, the drive unit 121 can be positioned at any location along the extension direction (i.e., the z-direction) of the vertical mounting portion 22. This frees up space on the mounting platform 23 for other components of the photovoltaic mounting equipment 100, improving space utilization.

[0038] In another variation, the drive unit 121 can be installed on the side of the horizontal support 21 closest to the vertical support 22. Therefore, by placing the drive unit 121 as close as possible to the vertical support 22, the offset of the main body's center of gravity can be more reliably mitigated, improving the overall stability of the machine.

[0039] In some embodiments, along the x-direction, the drive unit 121 and the trolley 11 can be located on opposite sides of the center of gravity of the main body 2. For example, the drive unit 121 and the trolley 11, mounted on the mounting platform 23, are located on opposite sides of the vertical support 22 along the x-direction. Alternatively, the drive unit 121 and the trolley 11 can both be mounted on the transverse support 21 and located on opposite sides of the vertical support 22 along the x-direction. Thus, the drive unit 121 can function similarly to a counterweight, preventing the center of gravity of the main body 2 from being too biased towards the end of the cantilever beam (e.g., Figure 1 The right end of the lateral support 21 in the field of view causes the main body 2 to overturn.

[0040] In a specific implementation, continue to refer to Figure 1 and Figure 2 The transmission mechanism 122 may include a traction rope 123 for connecting the trolley 11 and the drive unit 121. The drive unit 121 controls the trolley 11 to reciprocate in the x-direction by pulling the traction rope 123. For example, the traction rope 123 may be a steel wire rope to ensure sufficient structural strength.

[0041] Specifically, the trolley 11 has a first end 11a and a second end 11b opposite each other along the x-direction, and the traction rope 123 includes a first section 124 and a second section 125 that are independent of each other. The first section 124 connects the first end 11a and the drive unit 121, and the second end 11b is connected to the drive unit 121 via the second section 125.

[0042] Furthermore, both the first segment 124 and the second segment 125 include at least one segment extending along the x-direction. The drive device 121 is used to drive the first segment 124 and the second segment 125 respectively to drive the trolley 11 to move back and forth along the x-direction. For example, under the drive of the drive device 121, pulling the first segment 124 while releasing the second segment 125 can drive the trolley 11 to move in the opposite direction along the x-direction shown in the figure. As another example, under the drive of the drive device 121, releasing the first segment 124 while pulling the second segment 125 can drive the trolley 11 to move in the positive direction along the x-direction shown in the figure.

[0043] Thus, the trolley 11 and the drive unit 121 are connected in series to form a closed loop through the traction rope 123. The trolley 11 can be controlled to reciprocate along the x direction by the forward and reverse rotation of the same drive unit 121.

[0044] In some embodiments, continue to refer to Figure 1 and Figure 2 The drive unit 121 may include a first drum 126 and a second drum 127 that are independent of each other. The first drum 126 is connected to a first section 124 to adjust the extension length of the first section 124. The second drum 127 is connected to a second section 125 to adjust the extension length of the second section 125. The extension length refers to the length of the traction rope 123 extending between the drum and the trolley 11.

[0045] Furthermore, the drive unit 121 may also include a power unit 128 for driving the first drum 126 and the second drum 127. The power unit 128 may drive the first drum 126 and the second drum 127 to rotate in opposite directions, thereby shortening the extension length of one of the first section 124 and the second section 125 while increasing the extension length of the other.

[0046] For example, the power unit 128 may include a three-in-one motor reducer, an encoder, and a frequency converter. During the operation of the photovoltaic installation equipment 100, if it is necessary to control the movement of the trolley 11 in the positive x-direction, power is supplied to the power unit 128. The three-in-one motor reducer is powered on and rotates in the forward direction under the control of the encoder and the frequency converter, driving the first drum 126 to rotate in the forward direction while the second drum 127 rotates in the reverse direction. As the first drum 126 rotates in the forward direction, the extension length of the first section 124 increases, while at the same time, as the second drum 127 rotates in the reverse direction, the extension length of the second section 125 decreases, and the trolley 11 moves in the positive x-direction under the traction of the traction rope 123.

[0047] Similarly, if it is necessary to control the trolley 11 to move in the opposite direction of the x-axis, power is supplied to the power unit 128. The three-in-one motor reducer is powered on and rotates in reverse under the control of the encoder and frequency converter, driving the first drum 126 to rotate in reverse while the second drum 127 rotates in the forward direction. As the first drum 126 rotates in reverse, the extension length of the first section 124 decreases, while at the same time, as the second drum 127 rotates in the forward direction, the extension length of the second section 125 increases, and the trolley 11 moves in the opposite direction of the x-axis under the traction of the traction rope 123.

[0048] In one specific implementation, the first spool 126 and the second spool 127 can be located on the same side of the trolley 11, and said same side is the side closer to the first end 11a. For example, refer to Figure 1Along the x-direction, the first end 11a is located between the first drum 126, the second drum 127, the power unit 128 and the second end 11b.

[0049] Furthermore, a first pulley block 25 can be provided on the main body 2. One end of the second section 125 is connected to the second end 11b of the trolley 11, and the other end is connected to the second drum 127 after being turned by the first pulley block 25. For example, the first pulley block 25 may include a first fixed pulley 251, which is provided at the end of the transverse support 21 away from the vertical support 21. The second section 125 extends from the second end 11b in the positive x-direction to the first fixed pulley 251, and after being turned by the first fixed pulley 251, extends in the opposite x-direction to connect to the second drum 127. Thus, the first drum 126 and the second drum 127 can be integrated into one place, so that a single power unit 128 can control the operation of both drums simultaneously, reducing the number of parts and simplifying the structure.

[0050] Furthermore, after the second section 125 is turned via the first fixed pulley 251, it can pass above the trolley 11 in the z-direction. Thus, the extended path of the second section 125 avoids the trolley 11, the lifting device, and the photovoltaic module connected to the lifting device, ensuring that the components of the photovoltaic installation equipment 100 operate without interference.

[0051] In some embodiments, the section of the traction rope 123 extending in the x-direction can extend substantially along the transverse support 21. This reduces the section of the traction rope 123 that is suspended and exposed, protecting the traction rope 123 from accidental cut and preventing operators from accidentally touching the traction rope 123 and getting injured.

[0052] In one variation, the first pulley block 25 may include multiple cascaded fixed pulleys. The second section 125, extending from the second end 11b, is sequentially turned via these fixed pulleys and then extends in the opposite direction of the x-direction to the second drum 127. Thus, the multiple cascaded fixed pulleys can mutually protect each other, preventing the failure of a single fixed pulley from affecting the transmission effect of the second section 125. Furthermore, the multiple cascaded fixed pulleys can make the turning direction of the second section 125 more gentle, allowing the second section 125 to gradually turn from the positive x-direction to the opposite x-direction.

[0053] In one specific implementation, the drive unit 121 may not be positioned along the reciprocating motion path of the trolley 11 in the x-direction or its extension. In other words, the drive unit 121 and the trolley 11 are not at the same height in the z-direction. For example, refer to... Figure 1 The drive unit 121 is integrated on the mounting platform 23 and is located near the bottom of the vertical support 22, while the trolley 11 is located near the top of the vertical support 22.

[0054] Furthermore, a second pulley block 26 can be provided on the main body 2. One end of the first section 124 and the second section 125 are respectively connected to the trolley 11, and the other end is connected to the drive device 121 after being turned by the second pulley block 26. Thus, the second pulley block 26 realizes the turning of the transmission direction, so that the trolley 11 and the drive device 121, which are not on the same straight line, can still be reliably connected. Furthermore, the arrangement of the second pulley block 26 ensures that the traction rope 123 can remain parallel to the x-direction at least in the extension direction of the section closest to the trolley 11, so as to minimize force loss and improve traction efficiency.

[0055] In some embodiments, the second pulley group 26 may include a second fixed pulley 261 for turning the extension direction of the first section 124, and a third fixed pulley 262 for turning the extension direction of the second section 125. The second fixed pulley 261 and the third fixed pulley 262 may both be disposed on the main body 2 and located between the drive device 121 and the first end 11a.

[0056] For example, the first drum 126 is disposed near the bottom of the vertical support portion 22. The first section 124 extends from the first end 11a in the opposite direction of the x-direction to the second fixed pulley 261, and after being turned by the second fixed pulley 261, extends to the first drum 126 in the opposite direction of the z-direction.

[0057] For example, the second drum 127 is located near the bottom of the vertical support 22. The second section 125 extends from the second end 11b in the x-direction to the first fixed pulley 251, and after turning via the first fixed pulley 251, extends in the opposite direction of the x-direction to the third fixed pulley 262, and after turning via the third fixed pulley 262, extends in approximately the opposite direction of the z-direction to the second drum 127.

[0058] In some embodiments, the second pulley block 26 may be disposed at the connection between the vertical support portion 22 and the horizontal support portion 21. Therefore, the inflection point of the extension direction of the traction rope 123 is positioned close to the vertical support portion 22, which helps to ensure that the center of gravity of the main body 2 is close to the vertical support portion 22.

[0059] In some embodiments, the third fixed pulley 262 may be positioned above the second fixed pulley 261 along the z-direction. Further, the line connecting the third fixed pulley 262 and the first fixed pulley 251 may be parallel to the x-direction, ensuring that the extension direction of the second segment 125 between the third fixed pulley 262 and the first fixed pulley 251 is parallel to the x-direction. Further, the line connecting the second fixed pulley 261 and the first end 11a may be parallel to the x-direction, ensuring that the first segment 124 between the second fixed pulley 261 and the first end 11a extends along the x-direction.

[0060] In a variation, the transmission mechanism 122 can also be a chain. This also achieves power transmission between the drive unit 121 and the trolley 11.

[0061] In some embodiments, hollow pipes can be laid along the vertical support 22 and / or the horizontal support 21, with the traction rope 123 extending inside the pipes. This avoids the traction rope 123 being exposed and posing a safety risk.

[0062] In one variation, the vertical support 22 and / or the horizontal support 21 may be a truss structure, wherein one or more columns may be hollow to allow the traction rope 123 to pass through.

[0063] In a specific implementation, continue to refer to Figure 1 The vehicle 11 may include multiple independent vehicle modules 111, which are connected to the main body 2 at intervals along the y-direction. Thus, the vehicle 11 also adopts a split design to further reduce the weight of the vehicle 11.

[0064] Specifically, the number of multiple trolley modules 111 and the number of lateral support sections 21 can be appropriately matched. For example, the main body 2 may include two vertical support sections 22, spaced apart along the y-direction and supported on the mounting platform 23, wherein each vertical support section 22 carries a lateral support section 21. A trolley module 111 may be correspondingly installed below each lateral support section 21. The two ends of the lifting device along the y-direction are respectively connected to the two trolley modules 111.

[0065] Furthermore, the number of vehicle moving mechanisms 12 can be one. A single vehicle moving mechanism 12 simultaneously controls the movement of multiple vehicle modules 111, enabling the multiple vehicle modules 111 to move synchronously along the x-direction or synchronously in the opposite direction of the x-direction. For example, for each vehicle module 111, both ends of the vehicle module 111 along the x-direction are connected to the same drive device 121 via a first section 124 and a second section 125, respectively. Driven by a single drive device 121, the first section 124 connected to all vehicle modules 111 moves synchronously in the same direction, and the second section 125 connected to all vehicle modules 111 moves synchronously in the same direction, thus achieving synchronous movement of all vehicle modules 111 in the same direction.

[0066] In some embodiments, the vehicle mechanism 1 may include a plurality of vehicle moving mechanisms 12, each corresponding to a plurality of vehicle modules 111. Furthermore, the plurality of vehicle moving mechanisms 12 drive the plurality of vehicle modules 111 to reciprocate synchronously along the x-direction.

[0067] For example, continue to refer to Figure 1 and Figure 2A drive device 121 is respectively installed at the bottom of the two vertical support parts 22, and each drive device 121 is connected to the corresponding trolley module 111 via a corresponding transmission mechanism 122. Furthermore, by controlling the synchronous operation of each drive device 121, the synchronous driving of multiple trolley modules 111 to move synchronously in the same direction can be achieved.

[0068] In some embodiments, multiple transverse support portions 21 spaced apart along the y-direction can be connected by connecting beams 27. For example, refer to Figure 1 Each of the two transverse support sections 21 has a connecting beam 27 at both ends in the x-direction, and the connecting beam 27 extends in the y-direction. Thus, the transverse support sections 21 and the connecting beams 27 together form a quadrilateral structure, which helps to improve the structural stability of the main body section 2.

[0069] In one variation, the trolley 11 may straddle multiple transverse support sections 21 spaced apart along the x-direction. For example, see reference... Figure 3 The trolley 11 is mounted on two transverse support sections 21 at both ends along the y-direction, and is connected to the corresponding drive unit 121 via the corresponding transmission mechanism 122. This increases the length of the trolley 11 along the y-direction, ensuring the reliability of the lifting device connection.

[0070] In one variation, one end of the traction rope 123 can be connected to the top of the trolley 11 along the z-direction, and the other end can be connected to a drum. By controlling the operation of the power unit 128 to rotate the drum clockwise or counterclockwise, the extension length of the traction rope 123 can be extended or retracted.
