Description

Technical Field

[0001] The present application relates to the field of long object transport devices, and in particular to a transport vehicle. Background Art

[0002] When transporting long objects such as wind blades, extra-long transport vehicles are usually required. The center of gravity of the extra-long transport vehicle will change during transportation. When the center of gravity of the extra-long transport vehicle moves outside a certain area, the extra-long transport vehicle is prone to overturning accidents. Summary of the Invention

[0003] In view of the above situation, it is necessary to provide a transport vehicle to solve the problem that overlong transport vehicles are prone to overturning when carrying long objects for long-distance transportation.

[0004] Embodiments of the present application provide a transport vehicle comprising a movable load-bearing device and a monitoring system. The movable load-bearing device comprises a first load-bearing portion and a mounting assembly connected to the first load-bearing portion. The mounting assembly comprises a mounting member and an adjustment member. The mounting member is used to secure the transported object, and the adjustment member is connected to the mounting member and can adjust the posture of the transported object in at least one direction. The monitoring system is used to detect the position range of the center of gravity of the transport vehicle.

[0005] Monitoring the center of gravity position range of the transport vehicle provides a calculation basis for adjusting the center of gravity of the transport vehicle. Through the installation components in the movable carrying device, the transported objects such as wind turbine blades can adjust their posture to change the position of the center of gravity. Combined with the center of gravity position range obtained by the monitoring system, the overall center of gravity of the transport vehicle can be controlled to a reasonable area by adjusting the posture of the transported objects to avoid the transport vehicle from tipping over during transportation.

[0006] In a possible embodiment, the transport vehicle further includes an alarm system. The alarm system is communicatively connected to the monitoring system and is configured to issue an early warning signal when the monitoring system detects that the center of gravity position is outside a preset area.

[0007] When the monitoring system detects that the center of gravity position is outside the preset area, it means that the transport vehicle has a certain risk of overturning. At this time, the alarm system will sound an alarm to remind the driver to take corresponding actions.

[0008] In a possible embodiment, the transport vehicle includes a cockpit, and the alarm system includes an alarm component arranged in the cockpit.

[0009] The alarm is set in the cockpit to remind the driver in the cockpit to take effective measures in time to prevent the transport vehicle from tipping over.

[0010] In a possible embodiment, the transport vehicle includes a driver's cabin, and the alarm system includes an alarm component arranged outside the driver's cabin.

[0011] The alarm is set outside the cockpit to remind the driver outside the cockpit to take effective measures in time to prevent the transport vehicle from tipping over.

[0012] In a possible implementation manner, the alarm component includes at least one of a sound wave generator, a light generator, and a vibrator.

[0013] The alarm device can be either a sound wave generator or a light generator, or a combination of the two. Specifically, the sound wave generator can be a speaker or a mechanical alarm clock that emits sound waves to alert the driver. The light generator can be a warning light or an illumination light that emits sufficient light to alert the driver. The vibrator generates vibrations that the driver senses and receives a warning.

[0014] In a possible embodiment, the adjustment member includes a positioning member, which connects the mounting member and the first load-bearing portion, the mounting member is hinged to the first load-bearing portion, and the positioning member drives the mounting member to drive the transported object to adjust its posture.

[0015] The positioning member enables the mounting member to drive the fan blades to rotate around a hinge axis parallel to the ground. When the movable supporting device is placed on the ground, from the projection of the fan blades and the movable supporting device on the ground, when the fan blades are adjusted away from the second supporting part, that is, away from the ground through the adjustment of the positioning member, the projection of the fan blades on the ground becomes shorter, which can be matched by shortening the distance between the first supporting part and the second supporting part. In addition, when the fan blades rotate to move away from the ground, the supporting surface on the second supporting part also needs to be closer to the first supporting part in order to fit the surface of the fan blade.

[0016] In a possible embodiment, the adjusting member includes a rotary driving member, the mounting member has a mounting surface for fitting the end face of the transported object, and the rotary driving member is connected to the mounting member for driving the transported object to rotate around an axis perpendicular to the mounting surface.

[0017] Taking the transported object as a fan blade as an example, the above-mentioned rotary drive member drives the fan blade to rotate to change the windward surface of the fan blade when it is carried on the movable carrying device, thereby reducing the wind resistance of the fan blade.

[0018] In a possible embodiment, the adjusting member includes a turntable, the turntable is rotatably connected to the first bearing portion, and the mounting member is provided on the turntable to drive the transported object to rotate relative to the first bearing portion.

[0019] For example, the transported object is a wind turbine blade. The axis of rotation between the first support member and the turntable is perpendicular to the ground. Therefore, the turntable-driven mounting assembly moves the line of gravity of the transported object. The line of gravity, extending vertically downward from the center of the wind turbine blade, is used by the turntable to cause the entire blade to rotate approximately around its root, thereby causing the line of gravity to move closer to or further from the area containing the first support member, the telescopic member, and the second support member. When the wind turbine blade is transported by the movable support and encounters a turn, the shift in the position of the line of gravity adjusts the center of gravity of the entire blade to prevent tipping.

[0020] In a possible embodiment, the movable carrying device further comprises a telescopic member, wherein the telescopic member comprises a movable end capable of abutting against the ground. The control module is in communication with the telescopic member to control the telescopic member to extend and retract.

[0021] For example, in the case of wind turbine blades, a telescopic member is provided on at least one of the telescopic portion, the first load-bearing portion, and the second load-bearing portion. This allows the telescopic member to support and secure the movable load-bearing device in place, preventing it from sliding, when a movable load-bearing device is required for loading or unloading the wind turbine blades, or when the center of gravity position is outside the projection of the transport vehicle on the ground. The control module promptly transmits the monitored center of gravity position range as feedback to the movement of the telescopic member, enabling the transport vehicle to provide timely feedback to prevent tipping, significantly reducing the risk of tipping.

[0022] In a possible embodiment, the transport vehicle further includes a retractable member configured to drive the telescopic member toward or away from the first load-bearing portion. The control module is in communication with the retractable member to control the retractable member to drive the telescopic member to move.

[0023] For example, using wind turbine blades as transport objects, the retractable member can be moved further away from the transport vehicle's main body, thereby expanding the support range. When the vehicle's center of gravity is within this range, the risk of tipping is greatly reduced. The control module promptly feeds the monitored center of gravity position range into the movement of the retractable member, allowing the transport vehicle to respond promptly to prevent tipping, significantly reducing the risk of tipping.

[0024] In a possible embodiment, the transport vehicle further includes wheels, and the monitoring system calculates the center of gravity position range based on tire pressure data of the wheels.

[0025] By monitoring tire pressure data to calculate the center of gravity position range, a relatively accurate center of gravity position range result can be obtained.

[0026] In a possible implementation manner, the monitoring system includes pressure sensors disposed at at least two locations, and the monitoring system calculates the center of gravity position range through data from the pressure sensors.

[0027] By setting up multiple pressure sensors, the calculation result of the center of gravity position range is made more accurate. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0074] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a centrally located element. When an element is considered to be "disposed on" another element, it can be directly disposed on the other element or there may be a centrally located element. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0075] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0076] Embodiments of the present application provide a transport vehicle comprising a movable load-bearing device and a monitoring system. The movable load-bearing device comprises a first load-bearing portion and a mounting assembly connected to the first load-bearing portion. The mounting assembly comprises a mounting member and an adjustment member. The mounting member is used to secure the transported object, and the adjustment member is connected to the mounting member and can adjust the posture of the transported object in at least one direction. The monitoring system is used to detect the position range of the center of gravity of the transport vehicle.

[0077] Monitoring the center of gravity position range of the transport vehicle provides a calculation basis for adjusting the center of gravity of the transport vehicle. Through the installation components in the movable carrying device, the transported objects such as wind turbine blades can adjust their posture to change the position of the center of gravity. Combined with the center of gravity position range obtained by the monitoring system, the overall center of gravity of the transport vehicle can be controlled to a reasonable area by adjusting the posture of the transported objects to avoid the transport vehicle from tipping over during transportation.

[0078] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0079] Example 1

[0080] See also Figure 1 and Figure 2 The first embodiment of the present application provides a movable carrying device 010 for carrying long objects, such as wind turbine blades 030, for long-distance transportation. The device comprises a first carrying portion 100, a mounting assembly, a second carrying portion 300, a telescopic portion 500, and a connector 600.

[0081] The mounting assembly includes a mounting member 200 and an adjustment member. The mounting member 200 is hinged to the first support portion 100 via a hinge axis to achieve a movable connection with the first support portion 100. The mounting member 200 is used to mount the blade root 031 of the fan blade 030 and enables the fan blade 030 to move relative to the first support portion 100 in at least one direction to adjust the posture of the fan blade 030. The second support portion 300 has a bearing surface for supporting the blade body 033 of the fan blade 030. The telescopic member 500 connects the first support portion 100 and the second support portion 300. The telescopic member 500 can be extended and retracted to allow the first support portion 100 to move relatively closer to or farther from the second support portion 300. The connecting member 600 is disposed at the end of the first support portion 100 facing away from the second support portion 300 and is used to receive driving force and pull the first support portion 100, the mounting member 200, and the second support portion 300 to move on the ground.

[0082] Please also refer to Figure 3 The adjustment member includes a positioning member 400, which is used to adjust the posture of the fan blade 030 in one direction. The positioning member 400 connects the mounting member 200 and the first supporting part 100. The positioning member 400 is used to drive the mounting member 200 to move the fan blade 030 in a direction closer to or away from the second supporting part 300. The mounting member 200 and the positioning member 400 cooperate to enable the fan blade 030 to rotate on the first supporting part 100 around the hinge axis through the mounting member 200 relative to the first supporting part 100, thereby changing the angle between the fan blade 030 and the first supporting part 100. The first supporting part 100 and the second supporting part 300 are connected by the telescopic part 500, which can also adjust the overall length of the movable supporting device 010.

[0083] From the perspective of the projections of the fan blade 030 and the movable support device 010 on the ground, when the fan blade 030 is adjusted away from the second support portion 300 (i.e., away from the ground) by the adjustment member 400, the projection of the fan blade 030 on the ground becomes shorter. At this time, the distance between the first support portion 100 and the second support portion 300 is shortened, so that the support surface on the second support portion 300 is closer to the fan blade 030, and the support surface can continue to provide support for the fan blade 030. Because the position of the fan blade 030 on the first support portion 100 can be changed by the adjustment member 400, and the distance between the first support portion 100 and the second support portion 300 can be adjusted, the overall center of gravity of the movable support device 010 can be significantly changed, making it easy for the movable support device 010 to tip over during movement. Therefore, the connector 600 is disposed on the first support portion 350 so that the blade root 031 is close to the connector 600 that receives the driving force. By placing the center of gravity of the entire fan blade 030 close to the position where the movable supporting device 010 receives the driving force, the stability of the movable supporting device 010 can be improved. In addition, through the gravity of the blade root 031, the first supporting component 350 that receives the driving force has a relatively large pressure contact with the ground, thereby preventing the movable supporting device 010 from being pried up by the fan blade 030 near the driving force, making it difficult to displace through friction with the ground.

[0084] To ensure a stable connection between the mounting member 200 and the wind turbine blade 030, the mounting member 200 includes a flange 210 and a clamp 230. The flange 210 has a mounting surface 211 for contacting the end face of the blade root 031. The mounting surface 211 is used to contact the end face of the blade root 031. The end face of the blade root 031, i.e., the side of the blade root 031 facing away from the blade body 033, has a flat reference surface and multiple connecting ribs protruding from the reference surface. To ensure support for the blade root 031 and to avoid damage to the connecting ribs, the mounting surface 211 can be provided with multiple clearance holes for the connecting ribs to pass through. When the connecting ribs are inserted into the clearance holes, the reference surface portion of the end face of the blade root 031 is also in contact with the mounting surface 211, thereby ensuring that the mounting surface 211 provides better support for the wind turbine blade 030. When the fan blade 030 is located on the movable supporting device 010, it needs to be adjusted in position by the adjusting member 400. Therefore, the mounting member 200 only supports the blade root 031 and cannot drive the fan blade 030 to move. The clamp 230 is set on the flange 210 to further fix the fan blade 030. The clamp 230 is annular in shape, with a clamping space formed in the middle to clamp the outer peripheral surface of the blade root 031. In order to apply a clamping force to the outer periphery of the blade root 031 by the clamp 230, the clamp 230 includes a head 231 and a tail 233. The tail 233 can slide relative to the head 231 to change the size of the clamping space. When the clamping space is reduced to a certain position and provides sufficient clamping force for the outer periphery of the blade root 031, the relative positions of the head 231 and the tail 233 are fixed to fix the clamp 230 relative to the blade root 031.

[0085] After the mounting member 200 secures the fan blade 030, the positioning member 400 rotates the fan blade 030 as a whole. Since the fan blade 030 is relatively heavy, the positioning member 400 needs to exert a sufficiently large force to drive the fan blade 030 to move. The positioning member 400 uses a hydraulic cylinder, one end of which is connected to the first load-bearing portion 100 and the other end is connected to the mounting member 200. The hydraulic cylinder is perpendicular to the hinge axis between the mounting member 200 and the first load-bearing portion 100. The mounting member 200 rotates relative to the first load-bearing portion 100 by extending and retracting the hydraulic cylinder, and the mounting member 200 simultaneously drives the fan blade 030 to rotate relative to the first load-bearing portion 100. The number of hydraulic cylinders is not limited, but generally two hydraulic cylinders are symmetrically arranged on both sides of the mounting member 200. The two hydraulic rods can ensure force balance, making the rotation of the fan blade 030 smoother and more stable.

[0086] Specifically, one end of the hydraulic cylinder is connected to the first bearing part 100, and the other end is connected to the end of the mounting member 200 facing away from the hinge axis. The expansion and contraction of the hydraulic cylinder allows the mounting member 200 to drive the fan blade 030 to rotate around the hinge axis. The fan blade 030 is rotated around an axis perpendicular to the mounting surface 211 by the rotary drive member 700 in the adjustment member. Specifically, the rotary drive member 700 includes a chassis 710 and a drive motor 730, wherein the chassis 710 is fixed to the first bearing part 100, and an annular groove is provided on the chassis 710. An annular slider 213 is provided on the side of the flange 210 facing the chassis 710. The annular slider 213 is arranged in the annular groove to enable the flange 210 to rotate relative to the chassis 710 around an axis perpendicular to the mounting surface 211. The inner ring of the flange 210 is also provided with gear teeth (not shown). The drive motor 730 is fixed to the chassis 710. A gear is provided at the output end of the drive motor 730. The gear and the gear teeth are meshed so that when the gear rotates, the flange 210 can be driven to rotate. Because when the gears and the gear teeth are meshed, the force arm of the drive motor 730 portion is the radius of the gear, while the force arm of the flange 210 portion is the radius of the gear teeth. The radius of the gear teeth is much larger than the radius of the gear. This can reduce the power requirement of the drive motor 730, so that a motor with less power can also drive the fan blades 030 to move as a whole. The fan blades 030 rotate around an axis perpendicular to the mounting surface 211, which can reduce the wind resistance of the fan blades 030 when the movable carrier 010 moves on the ground. Reducing this wind resistance can prevent the fan blades 030 from detaching from the mounting member 200. On the other hand, it can enable the movable carrier 010 to be driven with less driving force to achieve a faster transportation speed.

[0087] In addition to being able to rotate about an axis perpendicular to the mounting surface 211 and relative to the first supporting portion 100 through the hinged connection between the mounting member 200 and the first supporting portion 100, the fan blade 030 can also be rotated via the turntable 130. Specifically, the adjustment member also includes the turntable 130, which is rotatably mounted on the base 110 of the first supporting portion 100. The mounting member 200 is fixedly mounted on the turntable 130. Therefore, when the turntable 130 rotates, it can drive the mounting member 200 to rotate, and the mounting member 200 can drive the fan blade 030 to rotate relative to the first supporting portion 100. Specifically, the base frame 110 includes a first section 111 arranged away from the second bearing part 300 and a second section 113 arranged close to the second bearing part 300. The turntable 130 is rotatably arranged on the first section 111. The hydraulic cylinder is arranged on the side of the mounting member 200 away from the second section 113, and the hinge shaft is arranged at one end of the mounting member 200 close to the second section 113. In order to enable the turntable 130 to drive the hinge shaft to rotate synchronously when it rotates, an arc groove is provided at a position of the second section 113 close to the first section 111, and both ends of the hinge shaft are arranged in the inner wall of the arc groove so that the hinge shaft can move with the rotation of the mounting member 200. The turntable 130 drives the fan blade 030 to rotate, causing the line of gravity of the fan blade 030 to move closer to or further away from the second carrying portion 300. When the movable carrying device 010 carries the fan blade 030 and moves on the ground and turns, the center of gravity of the fan blade 030 can be adjusted in advance to match the turn, so that the center of gravity of the fan blade 030 is relatively close to the center of the turn when the fan blade 030 turns, thereby reducing the possibility of the movable carrying device 010 tipping over. On the other hand, the turntable 130 can also be used to rotate the fan blade 030 so that the fan blade 030 can avoid obstacles during transportation.

[0088] The telescopic portion 500 connecting the first supporting portion 100 and the second supporting portion 300 includes a plurality of extension members 510. The first supporting portion 100 is connected to an extension member 510 at one end, and the second supporting portion 300 is connected to an extension member 510 at the other end. The extension members 510 are generally plate-shaped, with flanges on both sides. Two adjacent extension members 510 are slidably arranged, and through relative sliding, the two adjacent extension members 510 can have an overlapping state and an extended state. The overlapping state means that the projections of the two extension members 510 on the ground have a large overlap. The extended state means that the projections of the two extension members 510 on the ground have a small overlap or even no overlap. When the two extension members 510 are in the extended state, the distance between the first supporting portion 100 and the second supporting portion 300 is increased. Furthermore, the generally plate-shaped extension members 510 can isolate the fan blades 030 from the ground. By isolating the fan blades 030 from the ground, objects on the ground can be prevented from being lifted and scratching the surface of the fan blades 030. When the telescopic portion 500 is extended, the force acting on the second support portion 300 generates a large torque. Positioning the blade roots of the fan blades 030 close to the driving force prevents the first support portion 100 from being lifted by cargo, which would reduce the pressure between the position close to the driving force and the ground, thus affecting driving efficiency. When the two extension members 510 overlap, the distance between the first support portion 100 and the second support portion 300 can be reduced.

[0089] In order to enable the movable carrying device 010 to carry large wind turbine blades 030, when the telescopic part 500 is in the unfolded state, the overall length of the telescopic part 500 and the second carrying part 300 can reach more than 30,000 mm, and when in the overlapping state, the length is less than 9,000 mm.

[0090] When used to carry larger wind turbine blades 030, the size of the movable carrying device 010 can be further designed. For example, when the telescopic part 500 is in the unfolded state, the overall length of the telescopic part 500 and the second carrying part 300 reaches more than 40,000 mm. When the telescopic part 500 is in the overlapping state, the overall length of the telescopic part 500 and the second carrying part 300 reaches less than 10,000 mm.

[0091] It should be noted that the size of the movable carrying device 010 can be reasonably designed according to the size of the wind turbine blades 030 that actually need to be transported, and is not limited to the above-mentioned size.

[0092] To drive the adjacent extension members 510 between the overlapping and deployed states, thereby driving the first load-bearing portion 100 and the second load-bearing portion 300 toward or away from each other, the telescopic portion 500 further includes a telescopic control member (obscured by the flange in the figure and not shown). The telescopic control member can be a hydraulic cylinder or other structure such as a lead screw pair. When a lead screw pair is used, the lead screw is connected to one extension member 510, and the lead screw nut is provided on the other extension member 510. The rotation of the lead screw causes the extension member 510 on which the lead screw nut is provided to move toward or away from the extension member 510 on which the lead screw is provided.

[0093] The end of the blade body 033 of the fan blade 030 facing away from the blade root 031 is supported by the second support portion 300 to reduce the torque on the mounting member 200. However, since the fan blade 030 can rotate about an axis perpendicular to the mounting surface 211, it can rotate relative to the first support portion 100 through the hinged connection between the mounting member 200 and the first support portion 100, and can also move closer to or farther from the second support portion 300 via the turntable 130. Therefore, the relative positional relationship between the second support portion 300 and the fan blade 030 is dynamic. In order to provide stable support for the end of the blade body 033 of the fan blade 030 facing away from the blade root 031 in a dynamic environment, the second support portion 300 includes a mounting platform 310 and a support member 350. The mounting platform 310 is connected to the telescopic portion 500 to move closer to or farther from the first support portion 100, and has a mounting surface 211 on the mounting platform 310. Mounting surface 211 is provided with a guide groove extending toward first support portion 100, that is, parallel to the line connecting first support portion 100 and second support portion 300. Support member 350 slidably engages with the guide groove, allowing support member 350 to move relatively closer to or further away from first support portion 100 as it slides along the guide groove. When fan blade 030 changes position relative to second support portion 300, support member 350 slides a certain distance along the guide groove to match the change in position of fan blade 030, thereby enabling the bearing surface of support member 350 to provide stable support for fan blade 030.

[0094] See also Figure 3 and Figure 4When the wind turbine blades 030 need to be loaded and unloaded, the position of the movable carrier 010 needs to be fixed. In order to prevent the movable carrier 010 from being displaced due to the rolling of the wheel body 900, a telescopic member 800 is provided on the telescopic portion 500. The telescopic direction of the telescopic member 800 is perpendicular to the telescopic direction of the telescopic control member, so that the movable end 801 of the telescopic member 800 can be against the ground, thereby preventing the movable carrier 010 from moving relative to the ground through the static friction between the movable end 801 and the ground, and providing an additional support point to prevent the movable carrier 010 from tipping over. A flat plate can be provided on the movable end 801 of the telescopic member 800 to increase the contact area between the movable end 801 and the ground, thereby making the movable carrier 010 more stable when fixed. It should be noted that while the example of the telescopic members 800 used here to secure the movable carrier 010 to the ground is used to illustrate the function of the telescopic members 800, the movable carrier 010 can also be secured to a plaza, a dock, or other location, with the movable ends 801 of the telescopic members 800 contacting a supporting surface of the plaza, dock, or other location. Furthermore, the number of telescopic members 800 can also be four, six, or other numbers. Increasing the number of telescopic members 800 can prevent a situation where a small number of telescopic members 800 are unable to contact the ground, resulting in a difficulty in providing support for the movable carrier 010.

[0095] In order for the telescopic member 800 to prevent the movable carrier 010 from tipping over, it must be positioned as far away from the first carrier portion 100, the telescopic portion 500, and the second carrier portion 300 as possible, providing a large support area within which the center of gravity of the movable carrier 010 is located. Therefore, the telescopic member 800 is connected to the telescopic portion 500 via a retractable member. The telescopic portion 500 is positioned at the end of the retractable member. This retractable member allows the telescopic member 500 to be relatively distanced from the first carrier portion 100, thereby expanding the support area.

[0096] See also Figure 5The movable carrying device 010 is inevitably subject to turbulence during the transportation of the wind blade 030. In such a situation, the wind blade 030 may break away from the support surface. Excessive swing amplitude may even generate a large torque, causing it to break away from the mounting member 200. To prevent the wind blade 030 from making a relatively large displacement relative to the second carrying portion 300 due to turbulence, the carrying member 350 includes a frame 351, a first stopper 353, and a second stopper 355. The frame 351 slides in cooperation with the guide groove, the first limiting member 353 is fixed on the frame 351 to form a bearing surface roughly parallel to the ground to support the fan blade 030, and the second limiting member 355 is arranged on the frame 351 so that a limiting gap for inserting the blade body 033 is formed between the first limiting member 353 and the second limiting member 355. When encountering a bumpy situation, the fan blade 030 will avoid escaping from the limiting space of the bearing member 350 due to the limitation of the second limiting member 355, thereby preventing the fan blade 030 and the mounting member 200 from forming a large torque to detach from the mounting member 200.

[0097] In order to enable the movable carrying device 010 to travel on a road surface when driven by a driving force, the movable carrying device 010 further includes wheels 900. The wheels 900 are disposed on the first carrying portion 100 and the second carrying portion 300. This allows the overall center of gravity of the movable carrying device 010 to be located between the first carrying portion 100 and the second carrying portion 300, thereby ensuring the overall stability of the movable carrying device 010.

[0098] When this movable carrier 010 is actually used: the root 031 of the fan blade 030 is hoisted to a position close to the flange 210, and the root 031 of the fan blade 030 is fixed by the flange 210 and the clamp 230. The frame 351 of the carrier 350 slides along the guide groove to an appropriate position so that the bearing surface of the first limiting member 353 is in contact with the blade body 033 of the fan blade 030. The position of the second limiting member 355 is adjusted so that the blade body 033 of the fan blade 030 is located in a limiting gap of appropriate size. The movable carrier 010 is connected to the headstock 050, and the headstock 050 provides driving force for the movable carrier 010 so that the movable carrier 010 can move on the bearing bottom surface. When the fan blade 030 encounters a large wind resistance during transportation, the fan blade 030 is rotated by controlling the drive motor 730, thereby adjusting the wind resistance of the fan blade 030. When the fan blade 030 encounters a narrow turn, the telescopic portion 500 is used to make the first bearing portion 100 and the second bearing portion 300 relatively close to each other, reducing the overall size. In addition, the angle of the fan blade 030 relative to the first bearing portion 100 is adjusted by the positioning member 400 so that the center of gravity of the fan blade 030 is roughly between the first bearing portion 100 and the second bearing portion 300. The supporting member 350 can also be displaced through the guide groove to maintain contact with the fan blade 030 to provide support. When encountering a large and sharp turn, the turntable 130 can be used to adjust the line of action of the gravity of the fan blade 030 to a position close to the center of the turn to prevent tipping. In addition, if an obstacle is encountered during driving, the position of the fan blade 030 can also be adjusted to avoid the obstacle.

[0099] It should be noted that the wheel body 900 can also be replaced with a crawler track, as long as the movable carrying device 010 can travel on the ground.

[0100] It should be noted that the wheel body 900 may also be provided only on the first load-bearing portion 100, the telescopic portion 500, or the second load-bearing portion 300, or any two or all three thereof, as long as the first load-bearing portion 100, the telescopic portion 500, and the second load-bearing portion 300 can be supported on the ground as a whole.

[0101] It should be noted that the telescopic member 800 can also be set on the first bearing part 100 or the second bearing part 300 to provide support, as long as the movable end 801 can be against the support surface and the wheel body 900 can be separated from the support surface to fix the position of the movable bearing device 010.

[0102] The movable carrying device 010 can effectively avoid obstacles during transportation of the fan blades 030 and disperse the load to prevent damage to the fan blades 030. The adjustable spacing between the first carrying portion 100 and the second carrying portion 300 can also enable the fan blades 030 to pass through various types of curves during transportation.

[0103] Example 2

[0104] See also Figure 6 The second embodiment of the present application provides a movable carrying device 010. The difference between this movable carrying device 010 and the first embodiment is that:

[0105] A support arm 131 is provided on the turntable 130, extending away from the ground. The middle portion of the mounting member 200 is hingedly connected to the top of the support arm 131 via a hinge axis. A through-hole is provided in the support arm 131 near the turntable 130. The position adjustment member 400 passes through the through-hole and is hingedly connected to the side of the mounting member 200 near the turntable 130. The end of the position adjustment member 400 facing away from the mounting member 200 is hingedly connected to the support arm 131. The extension and retraction of the position adjustment member 400 controls the rotation of the mounting member 200 about the hinge axis in its middle.

[0106] The movable carrying device 010 can effectively avoid obstacles during transportation of the fan blades 030 and disperse the load to prevent damage to the fan blades 030. The adjustable spacing between the first carrying portion 100 and the second carrying portion 300 can also enable the fan blades 030 to pass through various types of curves during transportation.

[0107] Example 3

[0108] See also Figure 7 and Figure 8 The first embodiment of the present application provides a transport vehicle for carrying wind turbine blades 030 for long-distance transportation. This transport vehicle includes a vehicle head 050 and the movable carrying device 010 provided in Example 1. Vehicle head 050 is detachably connected to a connector 600 . Vehicle head 050 provides driving force to movable carrying device 010 , enabling movable carrying device 010 to move wind turbine blades 030 on the ground.

[0109] In order for the locomotive 050 to drive the movable carrier 010 to turn, the locomotive 050 needs to be rotatably connected to the movable carrier 010. Therefore, the connecting member 600 includes a bearing. The locomotive 050 is provided with a connecting post perpendicular to the ground. The connecting post is inserted into the bearing to enable the rotatable connection between the locomotive 050 and the movable carrier 010. The rotatable connection allows the locomotive 050 and the movable carrier 010 to change the connection angle, making it easier for the transport vehicle to turn.

[0110] In order to enable the vehicle head 050 to effectively support the movable carrying device 010, the first section 111 and the second section 113 of the base frame 110 are stepped, that is, the first section 111 is set farther away from the ground than the second section 113, so that part of the vehicle head 050 can extend under the first section 111, making the connection between the vehicle head 050 and the movable carrying device 010 more stable.

[0111] In addition, in order to enable the driver or the transport vehicle itself to know the center of gravity status and make timely adjustments, the transport vehicle also includes a monitoring system. The monitoring system monitors the center of gravity position range of the transport vehicle, and guides the adjustment of the posture of the wind turbine blade 030 by obtaining the center of gravity position range results, or causes the telescopic part 800 to be extended and retracted to avoid excessive deviation of the center of gravity and causing the transport vehicle to overturn.

[0112] The monitoring system obtains the pressure distribution of the transport vehicle by monitoring the tire pressure data of the wheels, and then calculates the approximate range of the center of gravity position through the pressure distribution calculation, that is, whether the center of gravity position is within or outside the projection range of the transport vehicle on the ground. In order to ensure that the center of gravity position range obtained by the monitoring system is accurate and effective, a multi-point layout of pressure sensors is required. The monitoring system includes pressure sensors arranged at at least two locations. The pressure conditions at different locations are obtained by the pressure sensors arranged at different locations, and then a relatively accurate center of gravity position range is calculated. The posture adjustment of the wind turbine blades 030 and the extension and retraction of the telescopic member 800 based on the center of gravity position range can accurately and effectively prevent the transport vehicle from tipping over.

[0113] The transport vehicle also includes an alarm system that cooperates with the monitoring system. The alarm system is installed on the body of the transport vehicle and a preset area can be set. When the monitoring system detects that the center of gravity position range is outside the preset area, it means that the transport vehicle has a certain risk of overturning. At this time, the alarm system issues an alarm to remind the driver to take corresponding operations.

[0114] The front end 050 of the transport vehicle has a cockpit, in which the driver operates the transport vehicle. The alarm system includes an alarm device installed in the cockpit. When the driver is in the cockpit, if the monitoring system detects that the center of gravity is outside the preset range, the alarm device in the cockpit can promptly alert the driver, so that the driver can take effective measures to prevent the transport vehicle from tipping over. The alarm system also includes an alarm device installed outside the cockpit. When the driver is not in the cockpit, if the monitoring system detects that the center of gravity is outside the preset range, the alarm device outside the cockpit can promptly alert the driver, so that the driver can either remotely operate or promptly enter the cockpit to take effective measures to prevent the transport vehicle from tipping over.

[0115] The alarm device can be any one of a sound wave generator, a light generator, and a vibrator, or a combination of any two or all three. Specifically, the sound wave generator can be a speaker or a mechanical alarm clock, as long as it can generate sufficient sound waves to alert the driver. The light generator can be a warning light or an illumination light, as long as it can generate sufficient light to alert the driver. The vibrator can generate vibrations that the driver can feel and receive a warning.

[0116] The actual center of gravity position range obtained by the monitoring device is used to adjust the transport vehicle, including the following situations:

[0117] During transport, if the monitoring system detects that the center of gravity has left or is nearly outside the projection of the transport vehicle on the ground, the transport vehicle will reduce its speed and the driver will control the extension of the retractable member, allowing the telescopic member 800 to promptly support the ground and expand the support area. If the monitoring system detects that the center of gravity is within a relatively safe area within the projection of the transport vehicle on the ground, the driver will control the retractable member to retract to prevent the telescopic member 800 from colliding with obstacles in the travel route.

[0118] In addition, during the transportation process, the driver controls the adjustment part to adjust the posture of the fan blade 030 so that the center of gravity position of the transport vehicle is adjusted. For example, when the transport vehicle is about to turn, the monitoring system first monitors the center of gravity position area, and then presets a terminal center of gravity position area according to the turning direction and arc. The terminal center of gravity position area is close to the axis position of the turn. When the center of gravity of the transport vehicle is in the terminal center of gravity position area, the transport vehicle turns, which can make the center of gravity of the transport vehicle have a smaller turning radius, thereby reducing the centrifugal force and avoiding tipping. For another example, when the transport vehicle is about to turn, the monitoring system first monitors the center of gravity position area. If the center of gravity position area is relatively high (that is, far away from the bottom surface), then when turning, the center of gravity of the transport vehicle forms a larger lever arm with the ground, and the centrifugal force at the center of gravity position of the transport vehicle will form a larger torque to cause the transport vehicle to have a tendency to tip over. In order to prevent the transport vehicle from tipping over, the control module controls the adjustment part to lower the center of gravity of the fan blade so that the center of gravity is close to the ground.

[0119] This transport vehicle can effectively avoid obstacles during transportation of the wind blades 030, and can disperse the load to prevent damage to the wind blades 030. The adjustable spacing between the first supporting portion 100 and the second supporting portion 300 can also enable the wind blades 030 to pass through various types of curves during transportation.

[0120] In addition, those skilled in the art may also make other changes within the spirit of this application. Of course, these changes made according to the spirit of this application should be included in the scope disclosed in this application.
