[0050] The tower base platform is an important structural component that supports the entire wind turbine generator set. It is usually located at the bottom of the wind turbine generator set and at a certain height from the ground. In addition, there is a basic tower on the tower base platform, and some electrical equipment related to the wind turbine generator set is installed in the basic tower.

[0051] In the related art, a ladder is set between the tower base platform and the ground, so that the operation and maintenance personnel can climb the ladder from the ground to the tower base platform, and then enter the base tower through the inspection door set on the base tower. When the electronic equipment in the base tower is damaged and needs to be replaced, the damaged electronic equipment is manually moved from the base tower to the ground, or the new electronic equipment is manually moved from the ground to the base tower. However, due to the large mass of the electronic equipment, manual transportation is time-consuming, resulting in low operation and maintenance efficiency.

[0052] Therefore, the present application provides a handling device for handling the target component of a wind turbine, including a first handling mechanism and a second handling mechanism; a sliding assembly is provided for connecting with the ladder of the wind turbine, and a support assembly is slidably provided on the sliding assembly for placing the target component; a driving assembly is provided and connected with the support assembly to drive the support assembly to slide relative to the sliding assembly; a fixed assembly is provided for connecting with the inner wall of the base tower of the wind turbine, and a hoisting assembly is provided and slidably connected with the fixed assembly to hoist the target component. Thus, during the operation and maintenance process, the target component can be placed on the support assembly, and the support assembly is driven by the driving assembly to transport the target component between the platform of the base tower of the wind turbine and the lower part of the ladder; the target component is hoisted between the platform and the inside of the base tower by sliding the hoisting assembly relative to the fixed assembly. In this way, the target component can be conveniently and quickly carried between the lower part of the ladder and the inside of the base tower, avoiding the need to manually carry the target component up and down the ladder or in and out of the base tower, thereby saving the handling time and improving the operation and maintenance efficiency.

[0053] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the utility model in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0054] like Figures 1 to 7 As shown, an embodiment of the present application provides a transport device for transporting a target component 600 of a wind turbine generator system, including a first transport mechanism 100 and a second transport mechanism 200 .

[0055] The first transport mechanism 100 includes a sliding assembly 110, a driving assembly 120 and a supporting assembly 130; the sliding assembly 110 is used to connect with the ladder 300 of the wind turbine; the supporting assembly 130 is slidably arranged on the sliding assembly 110, and the supporting assembly 130 is used to place the target component 600; the driving assembly 120 is connected to the supporting assembly 130, and the driving assembly 120 drives the supporting assembly 130 to slide relative to the sliding assembly 110 to transport the target component 600 between the platform 500 of the base tower 400 of the wind turbine and the lower part of the ladder 300.

[0056] The second transport mechanism 200 includes a fixing assembly 210 and a hoisting assembly 220 . The fixing assembly 210 is used to be set in the base tower 400 , and the hoisting assembly 220 is slidably set on the fixing assembly 210 . The hoisting assembly 220 is configured to hoist the target component 600 between the platform 500 and the inside of the base tower 400 .

[0057] Among them, the target component 600 can be an electrical equipment such as an inverter and a wind turbine installed in the basic tower 400, or it can be a mechanical connection component in the tower, etc. As long as it is a component of large mass that needs to be manually moved between the lower part of the ladder 300 and the inside of the basic tower 400, it can be configured according to the actual use requirements. The embodiments of the present application are only given as examples.

[0058] In addition, the ladder 300 is obliquely connected between the supporting surface of the base tower 400 and the platform 500 of the base tower 400, that is, the upper part of the ladder 300 is located on the platform 500, and the lower part is located on the supporting surface. The supporting surface can be the ground or other fixed surface with supporting strength. The embodiment of the present application is explained using the ground as an example.

[0059] In this application, if Figure 1 As shown, the sliding assembly 110 is arranged along the length direction of the ladder 300 , the supporting assembly 130 is slidably disposed on the sliding assembly 110 , and the sliding direction of the supporting assembly 130 is parallel to the ladder 300 .

[0060] Furthermore, the target component 600 is placed on the support assembly 130, and the support assembly 130 is connected to the drive assembly 120. Exemplarily, the drive assembly 120 can be a hydraulic mechanism or a gear transmission mechanism. For example, when the drive assembly 120 is a hydraulic telescopic assembly, one end of the telescopic assembly is connected to the support assembly 130; in this way, when the hydraulic telescopic component is extended or shortened, the support assembly 130 is driven to slide in different directions relative to the sliding assembly 110, that is, the support assembly 130 drives the target component 600 to slide in different directions relative to the ladder 300.

[0061] Furthermore, a fixing component 210 is provided on the inner wall of the base tower 400, and a hoisting component 220 is slidably connected to the fixing component 210, and the hoisting component 220 is used to hoist the target component 600; specifically, when the hoisting component 220 slides relative to the fixing component 210, the position of the target component 600 can be adjusted.

[0062] When used in the present application, the target component 600 is placed on the support assembly 130, and the support assembly 130 is driven by the driving assembly 120 to slide from the ground toward the platform 500 of the base tower 400 along the ladder 300. After approaching the platform 500, the target component 600 is hoisted to the installation position in the base tower 400 by the lifting assembly 220; or the lifting assembly 220 lifts the target component 600 from the installation position to the support assembly 130, and the target component 600 is transported to the ground along the ladder 300 by the sliding of the support assembly 130 relative to the sliding assembly 110.

[0063] It can be understood that the first transport mechanism 100 enables the target component 600 to move from the ground to the platform 500, or from the platform 500 to the ground; the second transport mechanism 200 enables the target component 600 to move from the platform 500 to the base tower 400, or from the base tower 400 to the platform 500. In this way, the target component 600 can be conveniently and quickly transported between the lower part of the ladder 300 and the inside of the base tower 400, eliminating the need to manually transport the target component 600 up and down the ladder 300 or in and out of the base tower 400, thereby saving transportation time and improving operation and maintenance efficiency.

[0064] In some embodiments, the present application further includes a control component, which is electrically connected to the control center of the wind turbine generator set, and the control component is electrically connected to the drive assembly 120. Exemplarily, the control component is an embedded controller or a single-chip microcomputer, etc., and the control component controls the drive assembly 120 to drive the support assembly 130 to slide relative to the sliding assembly 110 at a preset speed by writing a preset speed in the control component.

[0065] In specific settings, for example, when the driving component 120 is a gear transmission mechanism, the rotation speed of the gear can be controlled by the control component so that the sliding speed of the support component 130 matches the preset speed; for example, when the driving component 120 is a hydraulic telescopic mechanism, the hydraulic system parameters can be adjusted by the control component so that the sliding speed of the support component 130 matches the preset speed.

[0066] During specific use, the control component can be remotely opened through the control center or manually opened by the operation and maintenance personnel at the work site, so that the drive component 120 can slide smoothly at a preset speed under the control of the control component, thereby improving the safety of the target component 600 when sliding.

[0067] It should be noted that the above-mentioned preset speed is adaptively set by the operation and maintenance personnel according to the mass of the target component 600, the transportation distance and the established operation time. The embodiment of the present application does not limit this, and it can be adaptively set according to actual usage requirements.

[0068] In some embodiments, the present application also includes a detection component and a positioning component connected to the detection component, the detection component is electrically connected to each electronic component in the base tower 400, and the positioning component is electrically connected to the inspection terminal; during specific use, the detection component is used to detect whether each electronic component is working normally. If any electronic component is damaged and cannot work normally, the detection component will feed back the detection result to the positioning component. The positioning component will locate the wind turbine group where the electronic component is located, and feed back the positioning result to the inspection terminal of the operation and maintenance personnel, thereby facilitating the operation and maintenance personnel to quickly go to the corresponding wind turbine group.

[0069] In some embodiments, the sliding assembly 110 includes at least two slide rails 111 and corresponding sliders 112 slidably disposed on the slide rails 111 . Each slide rail 111 is used to be spaced apart at both ends of the steps of the ladder 300 , and the support assembly 130 is connected to each slider 112 .

[0070] The slide rail 111 and the slider 112 are both made of high-strength, low-density aluminum alloy, so that the slide rail 111 and the slider 112 have good load-bearing properties.

[0071] In this application, if Figures 1 to 3 As shown, at least two slide rails 111 are arranged on the ladder 300 at intervals. Specifically, the slide rails 111 extend from the lower part of the ladder 300 toward the platform 500, and the two slide rails 111 are respectively located at opposite ends of the steps of the ladder 300; when in use, the slide rails 111 are fixed to the ladder 300 in a detachable manner, so that the operation and maintenance personnel can flexibly apply the device to different wind turbines; illustratively, fastening holes 1111 are provided on the slide rails 111, and corresponding assembly holes are provided on the ladder 300, and fasteners such as bolts are sequentially passed through the fastening holes 1111 and the assembly holes to ensure that the slide rails 111 and the ladder 300 are reliably fixed.

[0072] Furthermore, each slide rail 111 is slidably provided with a slider 112. Exemplarily, the slider 112 is an inverted U-shaped hollow structure. The slider 112 is clamped with the slide rail 111 through an opening, that is, the opposite sides of the slider 112 are correspondingly clamped with the opposite sides of the slide rail 111. Thus, the slider 112 can slide along the length direction of the slide rail 111.

[0073] In actual use, at least two slide rails 111 are arranged at intervals, and the support assembly 130 is slidably connected to the corresponding slide rails 111 through the slider 112, so that the support assembly 130 is subjected to balanced force to avoid tilting; the slider 112 slides on the slide rail 111 to drive the support assembly 130 to slide relative to the slide rail 111, and then when the target component 600 is placed on the support assembly 130, the target component 600 slides relative to the ladder 300.

[0074] In some embodiments, a first protrusion 1112 and a first recess 1113 are sequentially provided on two opposite side walls of the slide rail 111 used to connect the slider 112, and a second recess 1122 and a second protrusion 1123 are correspondingly provided on at least one side of the slider 112, the first protrusion 1112 is correspondingly engaged with the second recess 1122, and the first recess 1113 is correspondingly engaged with the second protrusion 1123.

[0075] In this application, if Figures 2 to 4 As shown, a first convex portion 1112 and a first concave portion 1113 are sequentially provided on two opposite side walls of the slide rail 111 for connecting the slider 112 in an integrated manner; exemplarily, the first convex portion 1112 is an upward convex arc surface structure distributed along the sliding direction of the slide rail 111, and the first concave portion 1113 is a downward concave arc surface structure, and a second concave portion 1122 and a second convex portion 1123 are correspondingly provided on the slider 112, which are matched with the first convex portion 1112 and the first concave portion 1113 respectively.

[0076] In specific use, the first protrusion 1112 is correspondingly engaged with the second concave portion 1122, and the first concave portion 1113 is correspondingly engaged with the second protrusion 1123, so that the slider 112 is firmly inserted on the slide rail 111, and the first protrusion 1112 limits the second protrusion 1123 in the height direction of the slide rail 111. In this way, the slider 112 can only slide along the sliding direction of the slide rail 111, so as to prevent the slider 112 from being separated from the slide rail 111 during the sliding process.

[0077] In some embodiments, the support assembly 130 includes at least one support plate 131 . The support plate 131 is connected to each slider 112 . The side of the support plate 131 facing away from the slider 112 is used to place the target component 600 .

[0078] In this application, if Figures 1 to 3 As shown, the support assembly 130 includes a support plate 131 , wherein the support plate 131 may be made of materials such as stainless steel or high-strength alloy, so that the support plate 131 has good supporting force for the target component 600 .

[0079] In the specific configuration, the support plate 131 is located above the slider 112, and the support plate 131 and the slider 112 can be detachably connected by fasteners or clamping. For example, each slider 112 is provided with a first mounting hole 1121 on the side facing the support plate 131, and the support plate 131 is provided with a second mounting hole 1311 corresponding to the first mounting hole 1121. Fasteners such as bolts are passed through the second mounting hole 1311 and the first mounting hole 1121 in sequence to fix the support plate 131 on the corresponding slider 112. In this way, the target component 600 slides along the slide rail 111 with the support plate 131 driven by the slider 112, thereby realizing the transportation of the target component 600 from the ladder 300 to the platform 500.

[0080] In the embodiment of the present application, the side of the support plate 131 facing away from the slider 112 is used to place the target component 600. Exemplarily, an anti-skid pad is provided on the support plate 131 to increase the friction on the support plate 131, so that the target component 600 placed on the support plate 131 is not easy to slip.

[0081] In some embodiments, the support assembly 130 further includes at least one stopper 132 . The stopper 132 is disposed on the support plate 131 . The stopper 132 and the support plate 131 surround an installation position of the target component 600 .

[0082] In this application, if Figure 2 , Figure 5 and Figure 6 As shown, exemplarily, there are two stoppers 132, and both stoppers 132 are columnar structures. The stoppers 132 are spaced apart on the side of the support plate 131 toward the lower part of the ladder 300 by welding or bonding, that is, the stoppers 132 are located on the lower side of the support plate 131.

[0083] During specific use, when the target component 600 is placed on the support plate 131, one side of the target component 600 can be abutted against the stopper 132. In this way, when the support plate 131 slides relative to the slide rail 111, the stopper 132 supports the target component 600 to prevent the target component 600 from sliding off the support.

[0084] It should be noted that the structure, number and position of the stopper 132 are given for exemplary purposes only and can be adaptively set according to the actual usage scenario. The embodiment of the present application does not impose any restrictions on this. It is sufficient to ensure that the stopper 132 has a stopping effect on the target component 600 on the support plate 131.

[0085] In some embodiments, the support assembly 130 further includes at least one limiting member 133 , which is rotatably disposed on the support plate 131 , and a plurality of limiting holes 1114 are spaced apart on the slide rail 111 .

[0086] The limiting member 133 is configured to rotate relative to the supporting plate 131 when the supporting plate 131 slides to a preset position relative to the slide rail 111 so as to be inserted into the limiting hole 1114 corresponding to the preset position.

[0087] In this application, if Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, illustratively, a plurality of limit holes 1114 are provided at intervals on one surface of each slide rail 111 facing the support plate 131 by means of stamping and drilling processing methods, and correspondingly, two limit members 133 are provided at intervals on the support plate 131, and the limit members 133 and the support plate 131 can be rotatably connected by structural members such as hinges, so that the limit members 133 can rotate relative to the support plate 131.

[0088] In the embodiment of the present application, the two limit members 133 are located on the same side. When the support plate 131 slides to a preset position relative to the slide rail 111, the limit member 133 is rotated along a first direction relative to the support plate 131 to be inserted into the limit hole 1114 corresponding to the preset position, thereby fixing the position of the support plate 131 on the slide rail 111.

[0089] In some embodiments, two limit members 133 may be relatively arranged on both sides of the sliding direction of the support plate 131. When the support plate 131 slides to a preset position, the two limit members 133 may be plugged in front and back to fix the position of the support plate 131 on the sliding member.

[0090] It is understandable that before the support plate 131 slides again, the limiting member 133 is rotated relative to the support plate 131 along the second direction so that the limiting member 133 is disengaged from the limiting hole 1114 corresponding to the preset position, so as to release the limiting member 133 from limiting the support plate 131. The first direction and the second direction are opposite directions.

[0091] It should be noted that the preset position is any position where the support plate 131 stops sliding on the slide rail 111 as required for operation and maintenance operations; the limit member 133 can be a circular structure, a rectangular structure, etc., and the embodiment of the present application does not impose any restrictions on this, and it is sufficient to ensure that the limit member 133 can be plugged into the limit hole 1114 accordingly.

[0092] In some embodiments, the limiting member 133 includes a mounting portion 1331 and a rotating portion 1332 rotatably disposed on the mounting portion 1331, wherein the mounting portion 1331 is disposed on the support plate 131, and the rotating portion 1332 rotates relative to the mounting portion 1331 so that one end of the rotating portion 1332 away from the mounting portion 1331 is inserted into the limiting hole 1114 corresponding to the preset position.

[0093] In this application, if Figure 5 and Figure 6As shown, the limiting member 133 includes a mounting portion 1331 and a rotating portion 1332. Exemplarily, the mounting portion 1331 is a "7"-shaped structure, one end of the mounting portion 1331 is fixed to the support plate 131 by welding or bonding, and the other end has a rotating shaft; the rotating portion 1332 has a rotating shaft hole matching the rotating shaft, the rotating shaft hole is rotatably connected to the rotating shaft, and the extending direction of the rotating portion 1332 is perpendicular to the axis of the rotating shaft, so that the rotating portion 1332 rotates around the rotating shaft.

[0094] In specific use, when the support plate 131 slides to a preset position relative to the slide rail 111, the rotating part 1332 is rotated around the rotating shaft so that the axis of the rotating part 1332 is parallel to the axis of the corresponding limiting hole 1114 at the preset position, and when the projection of the rotating part 1332 in the axial direction is located in the limiting hole 1114, the end of the rotating part 1332 away from the rotating shaft can be inserted into the limiting hole 1114. In this way, the rotating part 1332 abuts against the inner wall of the limiting hole 1114, so that the limiting member 133 can fix the support member on the slide rail 111 at a preset position.

[0095] In some embodiments, the driving assembly 120 includes at least one driving member 121 , which is disposed at one end of the platform 500 facing the ladder 300 and connected to the support plate 131 ; the driving member 121 is configured to drive the support plate 131 to slide relative to the slide rail 111 .

[0096] In the embodiments of the present application, Figures 1 to 3 As shown, exemplarily, the driving member 121 can be a stepper motor, and the stepper motor is connected to the transmission structure. In a specific setting, the transmission structure can be a first gear rotatably connected to the motor, and a second gear arranged at one end of the support plate 131 facing the driving member 121. The first gear is meshed with the second gear to transmit the driving force of the stepper motor to the support plate 131, thereby driving the support plate 131 to slide relative to the slide rail 111.

[0097] By setting a stepper motor to convert the electrical energy of the stepper motor into mechanical motion, the electrical parameters of the stepper motor are used to control the sliding speed of the support plate 131, so that the support plate 131 can slide autonomously under the drive of the stepper motor, thereby avoiding the time-consuming and laborious manual pulling of the support plate 131.

[0098] In some embodiments, the number of the driving members 121 is two, and the driving assembly 120 further includes a driving wheel 122 corresponding to the driving member 121 , and the driving wheel 122 is rotatably disposed on the driving member 121 .

[0099] It also includes a traction component 140, which includes a traction member 141 and a hanging member 142 arranged corresponding to the driving wheel 122. The hanging member 142 is arranged on the support plate 131, and one end of the traction member 141 is arranged around the driving wheel 122, and the other end is connected to the hanging member 142.

[0100] In this application, if Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, there are two stepper motors, which are spaced apart on the platform 500 and respectively face one end of the slide rail 111 ; correspondingly, a driving wheel 122 is rotatably provided on the output shaft of the stepper motor, so that the rotation of the stepper motor drives the driving wheel 122 to rotate.

[0101] Further, the traction assembly 140 includes a traction member 141 and a hanging member 142. For example, the hanging member 142 is a hook, and the traction member 141 is a traction rope. In specific configuration, the traction member 141, the hanging member 142 and the driving wheel 122 are configured one by one. The hanging member 142 is configured at one end of the support plate 131 facing the driving member 121. One end of the traction member 141 is configured around the driving wheel 122, and the other end is connected to the hanging member 142.

[0102] In actual use, when the stepper motor is turned on, the corresponding driving wheel 122 is driven to rotate, and the traction rope on the driving wheel 122 is in a tensioned state to drive the support member to slide relative to the slide rail 111. By providing the driving wheel 122, the traction member 141 and the hanging member 142, the driving member 121 and the support plate 131 can be reliably transmitted, and the hanging member 142, the traction member 141 and the driving wheel 122 are easy to arrange at low cost, and are also convenient for later maintenance and replacement.

[0103] In some embodiments, the fixing assembly 210 includes a fixing ring 211 and a connecting piece 212. The fixing ring 211 is used to connect to the inner wall of the upper part of the base tower 400. The opposite ends of the connecting piece 212 are respectively rotatably connected to the fixing ring 211 so that the connecting piece 212 can rotate relative to the fixing ring 211.

[0104] The hoisting assembly 220 includes a hoisting member 221 and a pulley member 222 rotatably disposed on the hoisting member 221 . The hoisting member 221 is slidably disposed on the connecting member 212 to slide relative to the connecting member 212 . The pulley member 222 is used to connect with the target component 600 .

[0105] In this application, if Figure 1 and Figure 7As shown, the fixing ring 211 can be fixed to the inner wall of the upper part of the base tower 400 by interference fit or fastener connection; illustratively, the fixing ring 211 includes a first fixing ring 2111 and a second fixing ring 2112, and the first fixing ring 2111 is covered on the second fixing ring 2112 to enclose an annular slide groove.

[0106] Furthermore, the connecting member 212 is a connecting rod, and opposite ends of the connecting rod are provided with rollers respectively, and the rollers are inserted into the slide grooves, so that the connecting rod is driven by the rollers to rotate radially relative to the fixing ring 211.

[0107] In some embodiments, a bearing member is disposed inside the fixing ring 211 , and the connecting member 212 is rotatably connected to the bearing member, so that the connecting member 212 can rotate relative to the fixing ring 211 .

[0108] Furthermore, a hoisting member 221 is slidably provided on the connecting rod, and illustratively, the hoisting member 221 is a hoisting rope; it should be noted that the surface of the connecting rod is smooth, and the hoisting rope can slide along the length direction of the connecting rod on the connecting rod. At the same time, a pulley member 222 is provided on the hoisting rope, and the pulley member 222 can be connected to the hoisting rope as a movable pulley.

[0109] In this way, when the target component 600 needs to be transported between the platform 500 and the inside of the base tower 400, the target component 600 is connected to the pulley 222, and the position of the target component 600 in the vertical direction can be adjusted by pulling the lifting rope; by rotating the connecting rod and sliding the lifting rope on the connecting rod, the position of the target component 600 in the horizontal direction can be adjusted. In this way, the target component 600 can be transported to the target position without manual transportation, thereby saving transportation time and improving operation and maintenance efficiency. In addition, by setting the pulley 222 to be connected to the target component 600, it can have a labor-saving effect when the lifting rope pulls the target component 600.
