[0035] Wherein, the main vehicle 300 can be a main vehicle of a photovoltaic array installation device, or a main vehicle of other devices, which is not limited here. In the following, the micro-motion device 100 is taken as an example for further description when it is used in a photovoltaic array installation device.

[0036] Wherein, the hoisting frame 110 is used for supporting and moving the micro-motion frame 120 and the lifting appliance connected thereto. The hoisting frame 110 can move relative to the main vehicle 300, so as to move the lifting appliance and the hoisted photovoltaic panel to a designated position. Wherein, the micro-motion frame 120 is used for fine adjustment of the position of the lifting appliance. The micro-motion frame 120 can move relative to the hoisting frame 110 in a small range, so as to realize accurate positioning of the lifting appliance and the hoisted photovoltaic panel.

[0037] Wherein, the second direction of the movement of the micro-motion frame 120 and the first direction of the movement of the hoisting frame 110 can be the same direction, in which case the movement of the micro-motion frame 120 realizes fine adjustment of the position of the lifting appliance in the movement direction of the hoisting frame; the second direction of the movement of the micro-motion frame 120 and the first direction of the movement of the hoisting frame 110 can also be different directions, i.e. the first direction intersects the second direction.

[0038] As an optional embodiment, as shown in Figure 1 , the first direction is the X direction, and the second direction is the Y direction, the first direction and the second direction are arranged perpendicularly, in this embodiment, the second direction Y is the moving direction of the main vehicle of the photovoltaic array installation device, in which case the movement of the micro-motion frame 120 realizes fine adjustment of the position of the lifting appliance in the moving direction of the main vehicle.

[0039] Wherein, the micro-motion frame 120 can be one or more.

[0040] Wherein, the driving assembly is used for providing power for the micro-motion frame 120. The driving assembly comprises a plurality of driving mechanisms 130, in an example, the driving mechanism 130 can comprise a motor, a speed reducer, a transmission mechanism and the like, so as to realize motion control of the micro-motion frame 120.

[0041] The plurality of driving mechanisms 130 can be arranged on opposite sides of the micro-motion carriage 120 along the first direction X or the second direction Y. For example, the plurality of driving mechanisms 130 are arranged in pairs on opposite sides of the micro-motion carriage 120. Alternatively, the plurality of driving mechanisms 130 are asymmetrically arranged on opposite sides of the micro-motion carriage 120. For example, at least part of the driving mechanisms 130 are mounted on the hoisting carriage 110, and at least part of the driving mechanisms 130 are connected to the micro-motion carriage 120.

[0042] The micro-motion device provided in the embodiments of the present application can be used in the installation of a photovoltaic array. The hoisting carriage 110 is first moved relative to the main vehicle 300 along the first direction, thereby driving the micro-motion carriage 120, the lifting appliance, and the photovoltaic array hoisted by the lifting appliance to move to an installation position. Then, the micro-motion carriage 120 is moved relative to the hoisting carriage 110 along the second direction, thereby driving the photovoltaic array hoisted by the lifting appliance to be finely adjusted in position along the second direction, so that the photovoltaic array is accurately positioned with the photovoltaic support at the installation position, thereby ensuring accurate installation of the photovoltaic array.

[0043] The micro-motion device provided in the embodiments of the present application can be used in the installation of a photovoltaic array. The hoisting carriage 110 is first moved relative to the main vehicle 300 along the first direction, thereby driving the micro-motion carriage 120, the lifting appliance, and the photovoltaic array hoisted by the lifting appliance to move to an installation position. Then, the micro-motion carriage 120 is moved relative to the hoisting carriage 110 along the second direction, thereby driving the photovoltaic array hoisted by the lifting appliance to be finely adjusted in position along the second direction, so that the photovoltaic array is accurately positioned with the photovoltaic support at the installation position, thereby ensuring accurate installation of the photovoltaic array.

[0044] In one embodiment of the present application, the hoisting carriage 110 has a stroke range relative to the main vehicle 300 that is greater than a stroke range of the micro-motion carriage 120 relative to the hoisting carriage 110. For example, the stroke range of the micro-motion carriage 120 relative to the hoisting carriage 110 is within ±500 mm.

[0045] The hoisting carriage 110 is moved relative to the main vehicle 300 to achieve large-range movement and positioning of the lifting appliance. The micro-motion carriage 120 is moved relative to the hoisting carriage 110 to achieve small-range movement and positioning of the lifting appliance, thereby improving the installation accuracy of the photovoltaic array hoisted by the lifting appliance.

[0046] In one embodiment of the present application, as shown in FIG. 1, the hoisting carriage 110 is arranged on the main vehicle 300, and the micro-motion carriage 120 is arranged on the hoisting carriage 110. Figure 2As shown, the micro-motion device 100 includes two micro-motion carriages 120 spaced apart along the second direction, and a lifting device connected to the two micro-motion carriages 120. Each micro-motion carriage 120 is provided with a driving mechanism 130 on opposite sides thereof.

[0047] Exemplarily, the two micro-motion carriages 120 are spaced apart along the second direction Y, and each micro-motion carriage 120 is provided with a driving mechanism 130 on opposite sides thereof along the first direction X, for driving the micro-motion carriage 120 to move along the second direction Y relative to the lifting carriage 110.

[0048] The two micro-motion carriages 120 are provided to ensure the stability of the lifting device and the stability of the photovoltaic array when moved by the lifting device. The multiple driving mechanisms 130 synchronously drive the two micro-motion carriages 120 to move together, thereby realizing stable movement of the lifting device.

[0049] Figure 3 For Figure 2 A partial enlarged view of the middle A.

[0050] As Figure 3 shown, in some embodiments of the present application, the driving mechanism 130 includes a power output 131 and a transmission assembly 132. The transmission assembly 132 is connected to the micro-motion carriage 120, and the power output 131 is configured to output driving force and drive the micro-motion carriage 120 to move along the first direction on the lifting carriage 110 through the transmission assembly 132.

[0051] The power output 131 is used to provide driving force to the transmission assembly 132. Exemplarily, the power output 131 can be an electric motor, a hydraulic pump, a gas pump, etc. The transmission assembly 132 is used to transmit the driving force to the micro-motion carriage, so as to realize movement of the micro-motion carriage along the first direction relative to the lifting carriage 110. Exemplarily, the transmission assembly 132 can be a rack and pinion transmission, a chain wheel and chain transmission, a lead screw and nut transmission, a telescopic cylinder transmission, etc.

[0052] In addition, in some embodiments of the present application, the driving assembly includes a control unit 136 connected to each driving mechanism 130. The control unit 136 is used to control the multiple driving mechanisms 130 to synchronously drive the micro-motion carriages 120.

[0053] Exemplarily, the control unit 136 is connected to the power output 131, and the control unit 136 controls the multiple driving mechanisms 130 to synchronously move along the second direction Y through the power output 131.

[0054] In an embodiment of the present application, the power output 131 includes an electric motor, and the control unit 136 includes an encoder and a frequency converter. One or more encoders and frequency converters can be installed on the electric motors of the multiple driving mechanisms 130.

[0055] In the related art, the wheels of the micro-motion trolley 120 are directly driven by the power output member 131, which makes the wheels prone to slipping during movement. In the present application, the power output member 131 drives the transmission assembly 132 to move the micro-motion trolley 120, thereby reducing the risk of slipping of the micro-motion trolley 120 during movement. The running stability of the micro-motion trolley 120 is improved.

[0056] With reference to the foregoing Figure 3 In some embodiments of the present application, the transmission assembly 132 includes a guide portion 133 and a moving portion 134 movably connected with the guide portion 133. The guide portion 133 is arranged on the hoisting trolley 110 along the second direction. The moving portion 134 and the power output member 131 are both mounted on the micro-motion trolley 120. The power output member 131 is connected with the moving portion 134 and drives the moving portion 134 to move along the guide portion 133.

[0057] The guide portion 133 and the moving portion 134 improve the movement stability and precision of the micro-motion trolley 120.

[0058] The guide portion 133 provides a movement path for the moving portion 134. The guide portion 133 limits the stroke range of the moving portion 134. For example, the guide portion 133 is arranged on the hoisting trolley 110 along the second direction, such as along the longitudinal beam of the hoisting trolley 110. One or more guide portions 133 can be arranged on one longitudinal beam of the hoisting trolley 110.

[0059] In one example, a plurality of moving portions 134 move along one guide portion 133. In another example, one moving portion 134 moves along one guide portion 133.

[0060] The moving portion 134 moves along the guide portion 133 by interacting with the guide portion 133. For example, the moving portion 134 can be connected with the power output member 131 by a shaft or fixedly connected with the power output member 131. In one example, the moving portion 134 is fixedly connected with the micro-motion trolley 120 through the power output member 131, or the power output member 131 is fixedly connected with the micro-motion trolley 120 through the moving portion 134.

[0061] The moving portion 134 can be one or more, and is arranged on the micro-motion trolley along the extension direction of the guide portion.

[0062] Further, in one specific embodiment of the present application, the guide portion 133 can be a lead screw, and the moving portion 134 can be a nut.

[0063] Further, in another specific embodiment of the present application, the guide portion 133 can be a rack, and the moving portion 134 can be a gear matched with the rack.

[0064] The structure is simple, the movement precision of the micro-moving frame 120 is controlled by the precision of the meshing teeth on the gear and the rack, the control precision is higher, it is more convenient, and the space utilization rate is high.

[0065] With reference to the foregoing Figure 3 In other embodiments of the present application, the rack is supported by the angle steel 135 and arranged on the hoisting frame 110.

[0066] The angle steel 135 is an angular structure with two perpendicular sides, which provides stable support for the rack. The angle steel 135 can withstand the weight of the rack and various forces that may be generated during use, such as shear force, bending force, etc. With the support of the angle steel 135, the rack can maintain a stable position and posture, thereby ensuring the stability and reliability of the entire transmission system.

[0067] For example, along the extension direction of the rack, a plurality of angle steels 135 are arranged at intervals. It can effectively resist deformation and vibration. When the rack vibrates or impacts during transmission, the angle steel 135 can absorb and disperse the vibration or impact energy, reducing the impact on the hoisting frame 110, thereby improving the vibration resistance and durability of the photovoltaic array installation equipment.

[0068] As shown in Figure 2 In some embodiments of the present application, the micro-moving frame 120 is further provided with a moving support assembly 121 between the two sides thereof relative to the hoisting frame 110 along the first direction.

[0069] The moving support assembly 121 moves in contact with the hoisting frame 110 during the movement of the micro-moving frame 120 relative to the hoisting frame 110, and is supported on the hoisting frame 110.

[0070] The moving support assembly 121 improves the support capability of the micro-moving frame 120, provides stable support for the movement of the lifting device, and cooperates with the driving mechanism 130 to ensure the normal and stable movement of the micro-moving frame 120 while reducing the risk of slipping during the movement of the micro-moving frame 120.

[0071] In embodiments of the present application, the micro-moving frame 120 includes a frame body 122 and a moving support assembly 121 arranged on opposite sides of the frame body 122 along the first direction X, the moving support assembly 121 is movably arranged on the hoisting frame 110 along the second direction Y; the driving mechanism 130 is connected with the frame body 122.

[0072] For example, the moving support assembly 121 can be a wheel structure or other movable structure such as a track assembly. The moving support assembly 121 can be in rolling contact or sliding contact with the hoisting frame 110.

[0073] Part or all of the frame body 122 is positioned on the side of the lifting frame 110 away from the main body. In one example, the frame body 122 is positioned between two parallel longitudinal beams of the lifting frame 110.

[0074] like Figure 2 and Figure 3 As shown, in an optional embodiment of this application, the movable support assembly 121 includes at least one roller 123 disposed on the micro-motion frame 120. The roller 123 rolls in contact with the lifting frame 110 and moves along the lifting frame 110.

[0075] The roller 123 travels in the same direction as the guide 133. Through the rolling contact between the roller 123 and the lifting frame 110, the moving resistance of the micro-movement frame 120 is reduced, the moving speed is increased, and thus the installation efficiency of the photovoltaic array is improved.

[0076] In another optional embodiment of this application, the movable support assembly 121 includes at least one roller 123 disposed on the micro-motion frame 120 and a track structure 111 disposed on the lifting frame 110, wherein the roller 123 moves along the track structure 111.

[0077] The track structure 111 is mounted on the lifting frame 110 and is used to guide and support the rollers 123. Exemplarily, the extending direction of the track structure 111 is consistent with the extending direction of the guide portion 133.

[0078] The track structure 111 can be a flat plate structure, a guide groove structure, or a rail structure.

[0079] There can be multiple rollers 123, and the multiple rollers 123 are spaced apart along the extension direction of the track structure 111.
