Description

Technical Field

[0001] This disclosure relates to the field of photovoltaic equipment technology, and more specifically to a hoisting 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 main vehicle to support a trolley for lifting the PV panels. Due to the complex structure and heavy weight of the trolley, the main vehicle must also be enlarged in size or weight to stably support it and ensure its normal operation. This results in heavier and more expensive PV installation equipment. Utility Model Content

By configuring two lifting mechanisms and setting the relative positional relationship between the traction device of each lifting mechanism and the lifting point of the lifting device, the tilting operation of the lifting device is realized. Thus, while ensuring the normal lifting and tilting operations of the lifting device, a lightweight design for the trolley and the entire photovoltaic installation equipment is achieved.

[0033] 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.

[0034] The inventors of this application, through analysis, discovered that one of the reasons for the aforementioned technical problems is that the lifting device of the trolley needs to be raised and lowered under the drive of the drive unit to achieve the hoisting of the photovoltaic panels. However, 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 whole on the main vehicle. This results in a very large overall weight of 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.

[0035] To address the aforementioned technical problems, this disclosure provides a hoisting mechanism for photovoltaic installation equipment. The photovoltaic installation equipment includes a main body, and the hoisting mechanism includes: a trolley movably mounted on the main body; a lifting device located below and connected to the trolley, the lifting device being used to hoist photovoltaic modules; and a lifting mechanism connecting the lifting device and the trolley. The lifting mechanism includes a traction device and a drive device, the drive device controlling the lifting device to rise and fall relative to the trolley via the traction device; wherein the drive device is disposed within the photovoltaic installation equipment and is independently located outside the trolley.

[0036] By moving the drive unit that enables the lifting and lowering of the hoist from the trolley to another location on the photovoltaic installation equipment, the structure of the trolley is simplified, and its weight is significantly reduced. Furthermore, with the reduction in the complexity and weight of the trolley structure, a smaller and lighter main body can stably support the trolley and hoist, thereby greatly reducing the overall weight of the photovoltaic installation equipment and lowering the overall cost.

[0037] This implementation scheme can be applied to the field of photovoltaic module installation technology, where photovoltaic modules are installed at designated locations using the photovoltaic installation equipment provided in this disclosure. A photovoltaic module can be a single photovoltaic component or a pre-assembled photovoltaic array semi-finished product composed of multiple photovoltaic components.

[0038] To make the above-mentioned objects, features, and beneficial effects of this disclosure more apparent and understandable, embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The same reference numerals are used to denote the same parts in each drawing. The embodiments are merely illustrative, and of course, partial substitutions or combinations can be made to the structures shown in different embodiments. In the variations, descriptions of matters common to the first embodiment are omitted, and only the differences are described. In particular, the same effects produced by the same structure will not be mentioned one by one in each embodiment.

[0039] Figure 1 This is a schematic diagram of a photovoltaic installation device 100 according to the first embodiment of this disclosure. Figure 2 yes Figure 1 A schematic diagram of the lifting mechanism 3. Figure 3 yes Figure 2 A magnified view of a portion of region A in the middle.

[0040] Specifically, refer to Figures 1 to 3The photovoltaic installation equipment 100 may include a main body 2 and a hoisting mechanism 1. The main body 2 provides a support frame, specifically including a horizontal support 21 and a vertical support 22 for supporting the horizontal support 21. The hoisting mechanism 1 includes a trolley 11 movably mounted on the main body 2, and a lifting device 12 located below and connected to the trolley 11 along the z-direction. The lifting device 12 is used to hoist the photovoltaic modules. The trolley 11 drives the lifting device 12 to move relative to the main body 2. For example, the trolley 11 is movably mounted on the horizontal support 21, and the lifting device 12 can reciprocate along the extension direction of the horizontal support 21 with the trolley 11.

[0041] For ease of description, in this embodiment, the extension direction of the vertical support 22 is referred to as the z-direction (also known as the vertical direction), the extension direction of the horizontal support 21 is referred to as the x-direction, and the direction perpendicular to both the x-direction and the z-direction is referred to as the y-direction.

[0042] Furthermore, the bottom of the vertical support 22 has an installation platform 23, on which the vertical support 22 is directly or indirectly supported. 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.

[0043] Furthermore, the trolley 11 is mounted on the transverse support 21 and can reciprocate along the transverse support 21 under the control of the trolley moving mechanism. By controlling the trolley 11 to reciprocate relative to the transverse support 21 in the x-direction, the lifting device 12 and the photovoltaic module lifted by the lifting device 12 can be moved to the designated installation position.

[0044] Furthermore, the trolley 11 may include a trolley frame 111 and a micro-motion mechanism 112. The micro-motion mechanism 112 can move relative to the trolley frame 111 in the x and / or y directions to fine-tune the relative positions of the lifting device 12 and the main body 2 in the horizontal plane.

[0045] In the 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 12, under the control of the hoisting mechanism 3, lifts the photovoltaic module to be installed. At this time, the real-time position of the photovoltaic module and its target position in the installation area may be offset in the z-direction. The trolley moving mechanism is then controlled based on the positional deviation between the real-time and target positions of the photovoltaic module. This mechanism moves the trolley 11 along the x-direction or its opposite direction until the real-time and target positions of the photovoltaic module are substantially aligned in the z-direction. Then, the hoisting mechanism 3 controls the lifting device 12 to lower the photovoltaic module to the target position, completing the installation. During or before lowering the lifting device 12, the relative positions of the trolley frame 111 and the main body 2 in the horizontal plane can be further fine-tuned using the micro-motion mechanism 112 to ensure precise alignment of the real-time and target positions of the photovoltaic module in the z-direction.

[0046] To more clearly illustrate the specific structure of the hoisting mechanism in this embodiment, the trolley moving mechanism of the trolley 11 and the drive mechanism for driving the micro-motion mechanism 112 are omitted from the figure.

[0047] Further reference Figures 1 to 3 The hoisting mechanism also includes a lifting mechanism 3, which connects the lifting device 12 and the trolley 11. Specifically, the lifting mechanism 3 may include a traction device 31 and a drive device 32, with the drive device 32 controlling the lifting of the lifting device 12 relative to the trolley 11 via the traction device 31. The drive device 32 is located on the photovoltaic installation equipment 100, but is independent of the trolley 11. In other words, the drive device 32 is installed on the photovoltaic installation equipment 100 at a location other than the trolley 11.

[0048] This application moves the drive unit 32, which enables the lifting and lowering of the hoist 12, from the trolley 11 to other positions within the photovoltaic installation equipment 100, simplifying the structure of the trolley 11 and significantly reducing its weight. Furthermore, with the reduction in the structural complexity and weight of the trolley 11, a smaller and lighter main body 2 can stably support both the trolley 11 and the hoist 12, thereby greatly reducing the overall weight of the photovoltaic installation equipment 100 and lowering the overall cost. Furthermore, power transmission is achieved through the traction device 31, ensuring that the power of the drive unit 32, which is detached from the trolley 11, can be reliably transmitted to the hoist 12, enabling the hoist 12 to be lifted.

[0049] In this embodiment, as Figure 1As shown, the transverse support 21 is connected to the vertical support 22 at its midpoint along the extending direction. The drive device 32 can be installed on the transverse support 21 and is located on both sides of the vertical support 22, respectively, along with the trolley frame 111. Furthermore, the drive device 32 and the trolley 11 can be located on either side of the center of gravity of the main body 2. Specifically, the drive device 32 can be located at the end of the transverse support 21 away from the trolley frame 111, and the trolley frame 111 can reciprocate on the working section of the transverse support 21. The working section refers to the section of the transverse support 21 located between the vertical support 22 and the end away from the drive device 32. The transverse support 21 and the vertical support 22 can together form a lever structure. During the movement of the trolley frame 111 on the working section, the drive device 32 located at the other end of the lever can act like a counterweight to achieve load balance and 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 tipping over due to a deviation in its center of gravity, thus improving the overall stability of the machine. Of course, in some other embodiments, the position of the drive device 32 can be adjusted according to the specific situation. For example, the drive device 32 can also be arranged in other positions of the horizontal support 21, as long as it is close to the side of the vertical support 22. The drive device 32 can also be arranged on the vertical support 22 or on the mounting platform 23.

[0050] In a specific implementation, continue to refer to Figures 1 to 3 The vehicle 11 may include at least one vehicle module, that is, the number of vehicle modules may be one or more. When the vehicle includes multiple vehicle modules, the multiple vehicle modules may be distributed at intervals along the length direction of the photovoltaic module, that is, distributed at intervals along the y-direction. The first embodiment uses two vehicle modules as an example for demonstration.

[0051] Each trolley module may be equipped with at least two lifting mechanisms 3, each of which includes a traction device 31 and a drive device 32. The traction devices 31 of each lifting mechanism 3 are independent, and the drive devices 32 of each lifting mechanism 3 are independent. The traction devices 31 of the at least two lifting mechanisms 3 of each trolley module are respectively connected to the spreader 12 to form at least two lifting points, and the at least two lifting points are spaced apart in the width direction of the spreader 12.

[0052] In the first embodiment, each trolley module is equipped with two lifting mechanisms 3 as an example for demonstration. Specifically, the traction devices 31 of the two lifting mechanisms 3 are respectively connected to the lifting device 12 to form two lifting points. For ease of description, the two lifting points are referred to as the first lifting point 31a and the second lifting point 31b.

[0053] Furthermore, the drive units 32 of both lifting mechanisms 3 are disposed on the lateral support 21, and the vertical support 22 is located between the trolley frame 111 and the two drive units 32. One drive unit 32 controls the movement of the first lifting point 31a of the spreader 12 relative to the trolley 11 via a traction device 31, and the other drive unit 32 controls the movement of the second lifting point 31b of the spreader 12 relative to the trolley 11 via another traction device 31.

[0054] Furthermore, the first lifting point 31a and the second lifting point 31b are arranged at intervals in the width direction of the lifting device 12. The width direction of the lifting device 12 is parallel to the travel direction of the trolley 11 relative to the main body 2, i.e., the x-direction.

[0055] refer to Figure 1 Two trolley modules are respectively mounted on two transverse support sections 21, and each trolley module is equipped with two lifting mechanisms 3. Accordingly, the photovoltaic installation equipment 100 includes four drive devices 32 and four traction devices 31. The four traction devices 31 are respectively connected to the lifting device 12 to form two first lifting points 31a and two second lifting points 31b spaced apart along the y-direction.

[0056] In some embodiments, the two lifting mechanisms 3 can operate synchronously to control the reciprocating motion of the spreader 12 relative to the trolley 11 in the z-direction. In response to the simultaneous operation of the four drive units 32 at the same speed, the spreader 12 as a whole can be lifted or lowered in the z-direction.

[0057] In some embodiments, the two lifting mechanisms 3 can operate asynchronously to control the tilting of the spreader 12 relative to the horizontal plane. Specifically, the tilting of the spreader 12 relative to the horizontal plane is achieved by controlling each lifting point to rise and fall along the z-direction at different speeds, or by controlling some of the lifting points of at least two lifting points to rise and fall along the z-direction while the remaining lifting points remain stationary. For example, the tilting of the spreader 12 is achieved by controlling the first lifting point 31a and the second lifting point 31b to rise and fall along the z-direction at different speeds.

[0058] Therefore, by configuring two lifting mechanisms 3 and setting the relative positional relationship between the traction device 31 of each lifting mechanism 3 and the lifting point of the lifting device 12, the flipping operation of the lifting device 12 can be realized. Thus, the photovoltaic module can be lifted to the installation position at the required angle. Furthermore, while ensuring the normal implementation of the lifting and flipping operation of the lifting device 12, a lightweight design is achieved for the trolley 11 and the entire photovoltaic installation equipment 100.

[0059] In one variation, the trolley 11 may have three or more lifting mechanisms 3, and the lifting points formed by the traction device 31 of each lifting mechanism 3 and the lifting device 12 can be spaced apart along the width of the lifting device 12. Thus, in scenarios where the lifting device 12 is large in width, by setting a larger number of lifting mechanisms 3 to form a larger number of lifting points, the lifting device 12 can be ensured to move smoothly, avoiding damage to the photovoltaic module due to large swaying during the hoisting process.

[0060] In a specific implementation, continue to refer to Figures 1 to 3 The traction device 31 may include a traction rope 311 and a pulley assembly 312. The traction rope 311 and the pulley assembly 312 cooperate to connect the trolley 11 and the lifting device 12, allowing the lifting device 12 to be raised and lowered relative to the trolley 11. Thus, the lifting of the lifting device can be achieved through a simple structural design. The traction rope 311 and the pulley assembly 312 are both lightweight, which will not excessively increase the load on the main body 2, thus contributing to the lightweight design of the photovoltaic installation equipment 100.

[0061] Specifically, one end of the traction rope 311 is connected to the drive device 32, and the other end of the traction rope 311 passes sequentially through the first fixed pulley group 3121 set on the trolley 11, the first movable pulley group 3122 set on the lifting device 12, and the second fixed pulley group 3123 set on the trolley 11 before being connected to the main body 2.

[0062] Taking the trolley 11 with two lifting mechanisms 3 as an example, one end of a first rope 3111 is connected to a drive device 32, and the other end passes sequentially through a first fixed pulley group 3121, a first movable pulley group 3122, and a second fixed pulley group 3123 before being connected to the other end of the transverse support 21. The first movable pulley group 3122 is fixed to the lifting device 12 and forms a first lifting point 31a. One end of a second rope 3112 is connected to another drive device 32, and the other end passes sequentially through a first fixed pulley group 3121, a first movable pulley group 3122, and a second fixed pulley group 3123 before being connected to the other end of the transverse support 21. The first movable pulley group 3122 is fixed to the lifting device 12 and forms a second lifting point 31b.

[0063] Furthermore, the extension direction of the rope segments near both ends of the trolley 11 can be the direction of movement of the trolley 11 relative to the main body 2. That is, the sections of the trolley 311 extending between the drive unit 32 and the trolley 11, and between the trolley 11 and the end of the transverse support 21 away from the drive unit 32, extend substantially along the x-direction. This prevents the installation of the trolley 311 from interfering with the movement of the trolley 11 relative to the main body 2, ensuring smooth movement of the trolley 11.

[0064] Furthermore, both the first fixed pulley group 3121 and the second fixed pulley group 3123 are fixed to the trolley 11, while the first movable pulley group 3122 is fixed to the lifting device 12. The traction rope 311 extends from the drive device 32 along the x-direction to the first fixed pulley group 3121, turns to the z-direction via the first fixed pulley group 3121, extends downward to the first movable pulley group 3122, passes around the first movable pulley group 3122, extends upward to the second fixed pulley group 3123, then turns back to the x-direction via the second fixed pulley group 3123 and continues to extend to the end of the transverse support 21 away from the drive device 32.

[0065] During the hoisting operation, the traction rope 311 is loosened by the drive device 32. As the section of traction rope 311 between the fixed point of the transverse support 21 and the drive device 32 lengthens, the section of traction rope 311 between the first movable pulley block 3122 and the two fixed pulley blocks lengthens, and the first movable pulley block 3122 is lowered, realizing the descent of the lifting device 12. Conversely, the traction rope 311 is tightened by the drive device 32. As the section of traction rope 311 between the fixed point of the transverse support 21 and the drive device 32 shortens, the section of traction rope between the first movable pulley block 3122 and the two fixed pulley blocks shortens, and the first movable pulley block 3122 is pulled upward, realizing the lifting of the lifting device 12.

[0066] Thus, the cooperation of the traction rope 311 and the pulley assembly 312 achieves simple, efficient, and reliable force transmission, ensuring the stable lifting and lowering of the spreader 12. Furthermore, by adopting the winding method of the traction rope 311 provided in this embodiment, the spreader 12 will not be lifted during the translation of the trolley 11 relative to the lateral support 21.

[0067] In some embodiments, the first fixed pulley group 3121 and the second fixed pulley group 3123 can be arranged on the micro-motion mechanism 112. Thus, the lifting device 12 can synchronously adjust its relative position with the main body 2 along with the micro-motion mechanism 112, ensuring the accurate installation position of the photovoltaic module.

[0068] Specifically, continue to refer to Figures 1 to 3 The micro-motion mechanism 112 may include: a first micro-motion structure 113, connected to the trolley frame 111 and movable along a first direction; and a second micro-motion structure 114, connected to the first micro-motion structure 113 and movable along a second direction. In the first embodiment, the first direction is parallel to the y-direction, and the second direction is parallel to the x-direction. In other words, the first micro-motion structure 113 can be used to fine-tune the relative position of the lifting device 12 and the main body 2 in the y-direction. The second micro-motion structure 114 can be used to fine-tune the relative position of the lifting device 12 and the main body 2 in the x-direction.

[0069] Furthermore, the first fixed pulley group 3121 and the second fixed pulley group 3123 can be spaced apart along the x-direction on the second micro-motion structure 114. For example, the second micro-motion structure 114 has two sets of first fixed pulley groups 3121 and second fixed pulley groups 3123 spaced apart along the x-direction to correspond to the first rope 3111 and the second rope 3112, respectively. Each set of first fixed pulley groups 3121 and second fixed pulley groups 3123 is arranged spaced apart along the x-direction on the second micro-motion structure 114.

[0070] The movement of the trolley 11 under the action of the trolley moving mechanism and the movement of the first micro-motion structure 113 along the y-direction will drive the second micro-motion structure 114 to move synchronously. The lifting device 12 is connected to the trolley 11 through the traction rope 311 and the pulley assembly 312. Therefore, by installing the first fixed pulley assembly 3121 and the second fixed pulley assembly 3123 on the second micro-motion structure 114, it can be ensured that the movement of any component of the trolley moving mechanism, the first micro-motion structure 113, and the second micro-motion structure 114 can be reliably transmitted to the lifting device 12, thereby driving the lifting device 12 to move synchronously relative to the main body 2. In some embodiments, the second micro-motion structure 114 can be a generally integral plate-shaped structure, with the large surface of the plate-shaped structure perpendicular to the y-direction. Furthermore, two sets of first fixed pulley groups 3121 and second fixed pulley groups 3123 are arranged at intervals along the x-direction on the second micro-motion structure 114, which facilitates the arrangement of two first movable pulley groups 3122 at intervals along the x-direction to form two lifting points with the lifting device 12 in the x-direction, thereby realizing the lifting and tilting control of the lifting device 12.

[0071] In some embodiments, the first fixed pulley assembly 3121 may include a single fixed pulley, such as Figures 1 to 3 As shown. Alternatively, the first fixed pulley group 3121 may include multiple cascaded fixed pulleys to make the turning of the traction rope 311 between the first fixed pulley group 3121 and the first movable pulley group 3122 smoother. For example, the traction rope 311 may gradually turn from the x-direction to the z-direction via multiple cascaded fixed pulleys from the drive device 32.

[0072] Similarly, the first movable pulley group 3122 may include a single movable pulley, or it may include multiple cascaded movable pulleys. Similarly, the second fixed pulley group 3123 may include a single fixed pulley, or it may include multiple cascaded fixed pulleys.

[0073] In a specific implementation, continue to refer to Figures 1 to 3The drive unit 32 may include a drum 321 and a power unit 322. The drum 321 is connected to a traction rope 311 to adjust the extension length of the traction rope 311, which refers to the length of the traction rope 311 extending between the drum 321 and the fixed point of the traction rope 311 at the transverse support 21. The power unit 322 is used to drive the drum 321 to rotate to shorten or increase the extension length of the traction rope 311.

[0074] The power unit 322 may include a three-in-one motor reducer, an encoder, and a frequency converter. Taking the photovoltaic installation equipment 100, which includes four lifting mechanisms 3, as an example, to control the descent of the hoist 12 during operation, power is supplied to the power units 322 of all four lifting mechanisms 3. The four three-in-one motor reducers are powered on and rotate synchronously in the forward direction under the control of their respective encoders and frequency converters. The extension lengths of the four traction ropes 311 increase synchronously, and the four lifting points of the hoist 12 descend synchronously, thus achieving a smooth descent of the hoist 12.

[0075] Similarly, to control the lifting of the lifting device 12, power is supplied to the power units 32 of the four lifting mechanisms 3. The four three-in-one motor reducers are powered on and rotate synchronously in opposite directions under the control of their respective encoders and frequency converters. The extension lengths of the four traction ropes 311 are shortened synchronously, and the four lifting points of the lifting device 12 rise synchronously, thereby achieving the smooth lifting of the lifting device 12.

[0076] To control the lifting device 12 to rotate clockwise relative to the horizontal plane, selectively energize the power units 32 corresponding to two second lifting points 31b among the four lifting mechanisms 3, while de-energizing the other two power units 32 corresponding to the first lifting point 31a. The two energized three-in-one motor reducers are powered on and rotate synchronously in the forward direction under the control of their respective encoders and frequency converters, and the extension lengths of the two second ropes 3112 increase synchronously. Since the extension lengths of the two first ropes 3111 remain unchanged, the lifting device 12 rotates clockwise around the first lifting point 31a. To readjust the lifting device 12, the drum 321 corresponding to the second lifting point 31b can be controlled to rotate in the reverse direction to shorten the extension lengths of the two second ropes 3112 until the first lifting point 31a and the second lifting point 31b are level.

[0077] To control the lifting device 12 to rotate counterclockwise relative to the horizontal plane, selectively energize the power units 32 corresponding to the two first lifting points 31a among the four lifting mechanisms 3, while de-energizing the other two power units 32 corresponding to the second lifting points 31b. The two energized three-in-one motor reducers are powered on and rotate synchronously in the forward direction under the control of their respective encoders and frequency converters, and the extension lengths of the two first ropes 3111 increase synchronously. Since the extension lengths of the two second ropes 3112 remain unchanged, the lifting device 12 rotates counterclockwise around the second lifting point 31b. To readjust the lifting device 12, the drum 321 corresponding to the first lifting point 31a can be controlled to rotate in the reverse direction to shorten the extension lengths of the two first ropes 3111 until the first lifting points 31a and the second lifting points 31b are level.

[0078] To control the lifting device 12 to descend (or rise) while simultaneously rotating relative to the horizontal plane, power can be supplied to the power units 32 of the four lifting mechanisms 3. Furthermore, the rotation speed and / or rotation direction of the two three-in-one motor reducers corresponding to the first lifting point 31a and the two three-in-one motor reducers corresponding to the second lifting point 31b after being powered on under the control of their respective encoders and frequency converters are different. For example, any of the following control logics can be used: the extension lengths of the two first ropes 3111 shorten synchronously, and the extension lengths of the two second ropes 3112 increase synchronously; the extension lengths of the two first ropes 3111 increase synchronously, and the extension lengths of the two second ropes 3112 shorten synchronously; the extension lengths of the two first ropes 3111 increase synchronously, and the extension lengths of the two second ropes 3112 increase synchronously, and the rate of increase of the extension length of the first ropes 3111 is different from the rate of increase of the extension length of the second ropes 3112; the extension lengths of the two first ropes 3111 shorten synchronously, and the extension lengths of the two second ropes 3112 shorten synchronously, and the rate of shortening of the extension length of the first ropes 3111 is different from the rate of shortening of the extension length of the second ropes 3112. Thus, the lifting device 12 can be raised or lowered as a whole while simultaneously rotating relative to the horizontal plane.

[0079] In some embodiments, the traction rope 311 may extend approximately along the transverse support 21. This reduces the section of the traction rope 311 that is suspended and exposed, protecting the traction rope 311 from accidental cut and preventing operators from accidentally touching the traction rope 311 and getting injured.

[0080] In one variation, the drive unit 32 can be installed on the side of the transverse support 21 near the vertical support 22. Therefore, by placing the drive unit 32 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.

[0081] Figure 4 This is a schematic diagram of a photovoltaic installation device 200 according to the second embodiment of this disclosure. Figure 5 yes Figure 4 A schematic diagram of the cooperation between the micro-motion mechanism 112 and the traction device 31.

[0082] This section primarily focuses on the second embodiment and the above. Figures 1 to 3 The differences of the first embodiment shown will be explained.

[0083] Specifically, the photovoltaic installation equipment 200 shown in this embodiment is similar to the one described above. Figures 1 to 3 The main differences of the photovoltaic installation equipment 100 in the first embodiment shown include: the first direction is the x-direction and the second direction is the y-direction. For example, the first micro-motion structure 113 can be a frame structure that extends in a horizontal plane, and the second micro-motion structure 114 can be mounted on the frame of the first micro-motion structure 113 that extends in the y-direction and can move along the frame in the y-direction.

[0084] Furthermore, in addition to the first fixed pulley group 3121 and the second fixed pulley group 3123 spaced apart along the y-direction in the second micro-motion structure 114, and the first movable pulley group 3122 located between the first fixed pulley group 3121 and the second fixed pulley group 3123 along the y-direction and located below the first fixed pulley group 3121 and the second fixed pulley group 3123 along the z-direction and connected to the lifting device 12, the pulley assembly 312 shown in this embodiment may also include a third fixed pulley group 3124 and a fourth fixed pulley group 3125 disposed on the first micro-motion structure 113. The third fixed pulley group 3124 and the fourth fixed pulley group 3125 are arranged on both sides of the second micro-motion structure 114 in the y-direction. For example, the third fixed pulley group 3124 and the fourth fixed pulley group 3125 may be fixed at both ends of the frame extending along the y-direction of the first micro-motion structure 113.

[0085] Furthermore, the traction rope 311 passes through the first fixed pulley group 3121 and then through the third fixed pulley group 3124 to extend in the x-direction. Furthermore, the traction rope 311 passes through the second fixed pulley group 3123 and then through the fourth fixed pulley group 3125 to extend in the x-direction.

[0086] For example, refer to Figure 5 The two lifting mechanisms 3 of the trolley 11 can be arranged at intervals along the x direction. The pulley assembly 312 of each lifting mechanism 3 can include a third fixed pulley group 3124, a first fixed pulley group 3121, a first movable pulley group 3122, a second fixed pulley group 3123 and a fourth fixed pulley group 3125 arranged at intervals along the y direction.

[0087] One end of the first rope 3111 is connected to the drive device 32, and the other end extends along the x-direction to the third fixed pulley group 3124. After passing through the third fixed pulley group 3124, it turns to the opposite direction along the y-direction and extends to the first fixed pulley group 3121. After passing through the first fixed pulley group 3121, it turns to the z-direction and extends downward to the first movable pulley group 3122. The first rope 3111 then passes over the first movable pulley group 3122 and extends upward to the second fixed pulley group 3123, turning to the opposite direction along the y-direction. Finally, it passes through the fourth fixed pulley group 3125, turns back to the x-direction, and continues to extend to the end fixed to the transverse support 21. Furthermore, the first movable pulley group 3122, around which the first rope 3111 passes, can be connected to the lifting device 12 to form the first lifting point 31a. For example, the shaft of the first movable pulley group 3122 can be fixed to the lifting device 12 to ensure a reliable connection while maintaining the smooth movement of the first rope 3111.

[0088] One end of the second rope 3112 is connected to the drive device 32, and the other end extends along the x-direction to the third fixed pulley group 3124. After passing through the third fixed pulley group 3124, it turns to extend along the y-direction to the first fixed pulley group 3121. After passing through the first fixed pulley group 3121, it turns to the z-direction and extends downward to the first movable pulley group 3122. The first rope 3111 passes over the first movable pulley group 3122 and extends upward to the second fixed pulley group 3123, then turns to extend along the y-direction. Finally, it passes through the fourth fixed pulley group 3125 and turns back to the x-direction, continuing to extend to the end fixed to the transverse support 21. Furthermore, the first movable pulley group 3122, around which the second rope 3112 passes, can be connected to the lifting device 12 to form the second lifting point 31b. For example, the shaft of the first movable pulley group 3122 can be fixed to the lifting device 12 to ensure a reliable connection while maintaining the smooth movement of the second rope 3112.

[0089] This ensures that the section of the traction rope 311 passing through the second micro-motion structure 114 extends along the direction of movement of the second micro-motion structure 114, thus preventing the layout of the traction rope 311 from interfering with the movement of the second micro-motion structure 114.

[0090] In a specific implementation, continue to refer to Figure 4 and Figure 5 The photovoltaic installation equipment 200 shown in this embodiment is similar to the one described above. Figures 1 to 3 The main difference of the photovoltaic installation equipment 100 in the first embodiment shown also includes that the drive device 32 can be set on the installation platform 23. For example, the trolley 11 is movably installed on the transverse support 21, the drive device 32 is set on the installation platform 23, and the traction device 31 is arranged along the main body 2 to mechanically connect the hoist 12, the trolley 11 and the drive device 32.

[0091] Specifically, the horizontal support 21 and vertical support 22 of the photovoltaic installation equipment 200 described in this embodiment can form a cantilever beam structure. That is, one end of the horizontal support 21 along the extension direction is closer to the vertical support 22 than the other end.

[0092] Therefore, the lighter trolley 11 in this embodiment also helps improve the structural stability of the photovoltaic installation equipment 200. Specifically, even if the lighter trolley 11 moves the lifting device 12 and the photovoltaic module to the end of the horizontal support 21 away from the vertical support 22, it can still ensure that the center of gravity of the whole machine remains near the vertical support 22. This greatly reduces the probability of overturning due to the center of gravity of the main body 2 deviating, and improves the stability of the whole machine.

[0093] In some embodiments, the third pulley assembly 3124 can be a single pulley or multiple cascaded pulleys. Similarly, the fourth pulley assembly 3125 can be a single pulley or multiple cascaded pulleys. Multiple cascaded pulleys can cause the extension direction of the traction rope 311 to gradually change direction.

[0094] In some embodiments, continue to refer to Figure 4 The drive unit 32 may not be positioned on the movement path of the trolley 11 relative to the main body 2 or on its extension line. In other words, the drive unit 32 and the trolley 11 are not at the same height in the z-direction. For example, the drive unit 32 may be mounted on the mounting platform 23 and positioned near the bottom of the vertical support 22, while the trolley 11 may be positioned near the top of the vertical support 22.

[0095] Furthermore, the main body 2 may be equipped with a seventh fixed pulley group 3128. One end of the traction rope 311 is connected to the main body 2, and the other end is connected to the drive device 32 after being turned at least through the seventh fixed pulley group 3128. For example, one end of the traction rope 311 is connected to the drive device 32 provided on the mounting platform 23, and the other end extends upward to the seventh fixed pulley group 3128. After being turned through the seventh fixed pulley group 3128, it extends along the x-direction to the trolley 11. Then, the traction rope 311 passes sequentially through the third fixed pulley group 3124, the first fixed pulley group 3121, the first movable pulley group 3122, the second fixed pulley group 3123, and the fourth fixed pulley group 3125, and continues to extend along the x-direction to the end connected to the transverse support 21.

[0096] In some embodiments, the seventh fixed pulley block 3128 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 311 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.

[0097] In one variation, the drive unit 32 can be mounted on the vertical support 22. For example, the drive unit 32 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 200, improving space utilization.

[0098] Figure 6 This is a schematic diagram of a photovoltaic installation device 300 according to the third embodiment of this disclosure. Figure 7 yes Figure 6 A schematic diagram of the lifting mechanism 3.

[0099] This section primarily focuses on the third embodiment and the above. Figures 1 to 3 The differences of the first embodiment shown will be explained.

[0100] Specifically, the photovoltaic installation equipment 300 shown in this embodiment is similar to the one described above. Figures 1 to 3 The main difference in the photovoltaic installation equipment 100 described in the first embodiment is that one end of the traction rope 311 is connected to the drive device 32, and the other end of the traction rope 311 is connected to the lifting device 12 after passing through the fifth fixed pulley group 3126 set on the trolley 11. That is, the two ends of the traction rope 311 are respectively connected to the lifting device 12 and the drum 321. The connection point of the first rope 3111 and the lifting device 12 forms the first lifting point 31a, and the connection point of the second rope 3112 and the lifting device 12 forms the second lifting point 31b.

[0101] Furthermore, the fifth fixed pulley group 3126 can be disposed on the second micro-motion structure 114. Taking the trolley 11 as having two lifting mechanisms 3 as an example, each of the two lifting mechanisms 3 includes a fifth fixed pulley group 3126, and the two fifth fixed pulley groups 3126 are disposed at intervals along the x-direction on the second micro-motion structure 114.

[0102] For example, refer to Figure 7 One end of the first rope 3111 is connected to the lifting device 12 to form a first lifting point 31a, and the other end extends upward, passes through one of the two fifth fixed pulley groups 3126, and then extends in the opposite direction of the x-direction to the connecting drum 321. Similarly, one end of the second rope 3112 is connected to the drum 321, and the other end extends in the x-direction, passes through the other of the two fifth fixed pulley groups 3126, and then extends downward to the connecting device 12 to form a second lifting point 31b.

[0103] Therefore, while ensuring the reliability of lifting and tilting operations of the spreader 12, the number of components in the pulley assembly 312 is reduced, resulting in a lighter load on the lateral support 21, further conforming to the lightweight design concept. Furthermore, the traction rope 311 only needs to pass through the fifth fixed pulley group 3126 for single-stage transmission and steering between the drive unit 32 and the spreader 12, minimizing wear on the traction rope 311 as it passes through the pulleys. The entire transmission path is also simpler, allowing the force of the drive unit 32 to be transmitted to the spreader 12 with less loss, saving power consumption of the drive unit 32. In addition, the simplification of components also helps reduce costs.

[0104] In one variation, the drive unit 32 can be mounted on the installation platform 23, with one end of the traction rope 311 connected to the lifting device 12, and the other end passing through the fifth fixed pulley group 3126 and the seventh fixed pulley 3128 in sequence before being turned to connect to the drive unit 32.

[0105] Figure 8 This is a schematic diagram of a photovoltaic installation device 400 according to the fourth embodiment of this disclosure. Figure 9 yes Figure 8 A schematic diagram of the lifting mechanism 3.

[0106] This section primarily focuses on the fourth embodiment and the above. Figure 6 and Figure 7 The differences in the third embodiment shown will be explained.

[0107] Specifically, the photovoltaic installation equipment 400 shown in this embodiment is similar to the one described above. Figure 6 and Figure 7 The main difference of the photovoltaic installation equipment 300 in the third embodiment shown includes: in addition to the fifth fixed pulley group 3126 provided in the second micro-motion structure 114, the pulley assembly 312 of the photovoltaic installation equipment 400 also includes a sixth fixed pulley group 3127 provided in the main body 2, and the sixth fixed pulley group 3127 is located on the side of the trolley 11 away from the drive device 32. For example, the sixth fixed pulley group 3127 and the drive device 32 can be respectively provided at both ends of the transverse support 21 along the extension direction (e.g., the x direction).

[0108] Furthermore, one end of the traction rope 311 is connected to the drive device 32, and the other end is turned by the sixth fixed pulley 3127 and extends to the side of the trolley 11 and is connected to the fifth fixed pulley group 3126.

[0109] For the two lifting mechanisms 3 configured on the same trolley 11, the pulley assembly 312 of one lifting mechanism 3 may only include the fifth fixed pulley group 3126, while the pulley assembly 312 of the other lifting mechanism 3 may include both the fifth fixed pulley group 3126 and the sixth fixed pulley group 3127. For example, refer to Figure 9One end of the first rope 3111 is connected to the lifting device 12 to form a first lifting point 31a, and the other end is turned via the fifth fixed pulley group 3126 to extend in the x direction, and then turned via the sixth fixed pulley group 3127 to extend in the opposite direction of the x direction until it is connected to the drive device 32; while one end of the second rope 3112 is connected to the lifting device 12 to form a second lifting point 31b, and the other end is turned via the fifth fixed pulley group 3126 to extend in the opposite direction of the x direction and then directly connected to the drive device 32.

[0110] Therefore, the sections of the first rope 3111 and the second rope 3112 extending along the direction of movement of the trolley 11 relative to the main body 2 (e.g., the x direction) are spaced a certain distance apart in the y direction, which helps to avoid wear and tear caused by mutual friction between the two traction ropes 311 during their respective movements.

[0111] In a common embodiment of the first to fourth embodiments described above, a hollow pipe can be laid along the vertical support portion 22 and / or the horizontal support portion 21, with the traction rope 311 extending inside the pipe. This avoids the safety risks caused by the traction rope 311 being exposed.

[0112] 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 311 to pass through.

[0113] In a common embodiment of the first to fourth embodiments described above, the arrangement of at least two vehicle modules enables the vehicle 11 to also adopt a split design, thereby further reducing the weight of the vehicle 11.

[0114] Specifically, the number of at least two trolley modules 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 may be installed below each lateral support section 21. The two ends of the lifting device 12 along the y-direction are respectively connected to the two trolley modules.

[0115] Furthermore, each trolley module is equipped with at least two lifting mechanisms 3. For example, the number of lifting mechanisms 3 configured in at least one trolley module may differ from the number of lifting mechanisms 3 configured in other trolley modules. Alternatively, the number of lifting mechanisms 3 configured in each trolley module may be the same.

[0116] In one variation, the trolley 11 can bridging multiple transverse support sections 21 spaced apart along the y-direction. For example, the two ends of the trolley 11 along the y-direction are respectively mounted on two transverse support sections 21. As a result, the length of the trolley 11 along the y-direction is increased, ensuring the reliability of the connection of the spreader 12.

[0117] In a common embodiment of the first to fourth embodiments described above, multiple transverse support portions 21 spaced apart along the y-direction can be connected by connecting beams 25. For example, refer to... Figure 1 Each of the two transverse support sections 21 has a connecting beam 25 at both ends in the x-direction, and the connecting beam 25 extends in the y-direction. Thus, the transverse support sections 21 and the connecting beams 25 together form a quadrilateral structure, which helps to improve the structural stability of the main body section 2.

[0118] Furthermore, the drive unit 32 can be disposed on the connecting beam 25, such as... Figure 1 , Figure 6 and Figure 8 As shown.

[0119] In a common embodiment of the first to fourth embodiments described above, multiple suction cups 121 may be arranged in an array below the lifting device 12 for adsorbing the photovoltaic module to achieve the lifting of the photovoltaic module.

[0120] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
