DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The features and performance of a portable vehicle for assembling wind farm blade components of the present invention are further described in detail below in conjunction with the embodiments.

[0038] An embodiment of a portable vehicle for assembling wind farm blade components of the present invention, hereinafter referred to as a portable vehicle, is shown in FIG. Figures 1 to 12As shown, the portable vehicle includes a walking device, a lifting device, and a sliding operating device. The walking device includes a frame base 2, a universal wheel 1, and a pull rod 13. The lifting device includes a lifting platform 6, two sets of lifting mechanisms, each set of lifting mechanisms includes a telescopic mechanism 5, a lifting bracket 4, a folding pedal 14, and a lifting controller 3, wherein the lifting platform 6 has a groove 7 that matches the fixed buckle 10 in the sliding operating device to lock the sliding operating device with the lifting platform 6, and a rack 8 that matches the gear 18 in the sliding operating device to enable the sliding operating device to slide on the lifting platform. The sliding operating device includes a fixed buckle 10, a guardrail 12, an operating platform 9, and a sliding controller 11.

[0039] The bottom end of the lifting device is arranged on the frame base 2 of the walking device, wherein the bottom of each lifting mechanism is arranged on the corresponding frame base 2, the operating platform 9 of the sliding operating device is arranged on the lifting platform 6 at the top of the lifting device, and the pull rod 13 is arranged on the guardrail 12. A plurality of universal wheels 1 with brakes are arranged at the bottom of each frame base 2. When the lifting device is retracted and lowered, the operator can push and pull the pull rod 13 to make the portable vehicle move on the ground. After the lifting device is raised, the height of the lifting platform 6 from the ground can be higher than the height of the top of the root of the wind turbine blade to be installed from the ground. The portable vehicle can be pushed so that the lifting platform 6 spans over the root of the blade and moves along the entire blade, which is convenient for installing parts at various positions. The universal wheels 1 at the bottom of the frame bases 2 on both sides are braked to fix the portable vehicle, so that the assembler can assemble the blade components on the operating platform 9.

[0040] Two groups of lifting mechanisms are symmetrically arranged on both sides of the bottom of the lifting platform 6, and one of the groups is used as an example for description. The lifting controller 3 of the lifting mechanism is arranged on the frame base 2, and is used to control the extension or contraction of the lifting bracket 4 and the telescopic mechanism 5. The lifting bracket 4 includes a plurality of scissor structures distributed vertically and connected in sequence. The scissor structure includes a first rod 401 and a second rod 402 hinged to each other at the middle position, and the first rod 401 and the second rod 402 are hinged to each other through a first pin 403 that is simultaneously arranged in the middle position of the first rod 401 and the second rod 402. The telescopic mechanism 5 includes a plurality of telescopic rods 501 distributed vertically and connected in sequence head to tail. The telescopic rods 501 of the telescopic mechanism 5 correspond to the scissor structures of the lifting bracket 4 one by one, the middle part of the telescopic rod 501 is fixed on the corresponding first pin 403, and the two ends of the telescopic rod 501 are telescopic parts 502 that can be extended and retracted at the same time. In this embodiment, the telescopic part 502 adopts a multi-stage hydraulic cylinder (telescopic hydraulic cylinder) or a multi-stage electric push rod.

[0041] The telescopic rod 501 and the scissor-type structure constitute a lifting unit. A set of lifting mechanisms is formed by connecting a plurality of lifting units in sequence in the vertical direction. In this embodiment, a total of three lifting units are used. A flange 503 is provided at the end of the telescopic portion 502. In two adjacent lifting units, the flange 503 of the telescopic portion 502 at the top of the telescopic rod 501 below and the flange 503 of the telescopic portion 502 at the bottom of the telescopic rod 501 above are fixedly connected by bolts and nuts. In the adjacent scissor-type structures, the top of the first rod 401 below is hinged to the bottom of the second rod 402 above, and the top of the second rod 401 below is hinged to the bottom of the first rod 402 above.

[0042] Located in the middle lifting unit, such as Fig. 9 As shown, the flanges 503 of the telescopic parts 502 at the upper and lower ends of the telescopic rod 501 are respectively connected to the flanges 503 of the upper lifting unit and the flanges 503 of the lower lifting unit through bolts and nuts. The top of the first rod 401 is hinged to the bottom of the second rod 402 of the upper lifting unit, and the bottom of the first rod 401 is hinged to the top of the second rod 402 of the lower lifting unit. The top of the second rod 402 is hinged to the bottom of the first rod 401 of the upper lifting unit, and the bottom of the second rod 402 is hinged to the top of the first rod 401 of the lower lifting unit.

[0043] In the lifting unit located at the bottom, the end of the telescopic part 502 at the bottom of the telescopic rod 501 is slidably connected to the frame base 2. The bottom of the first rod 401 is slidably connected to the frame base 2, and a slider is provided at the bottom of the first rod 401. The slider is slidably provided in the slide groove of the frame base 2. The structure of the slider and the slide groove is a dovetail groove structure. The sliding connection structure between the bottom of the telescopic rod 501 and the frame base 2 can also adopt a dovetail groove structure; the bottom of the second rod 402 is hinged on the frame base 2. In this embodiment, a driving device such as an ordinary hydraulic cylinder or an ordinary electric push rod is provided on the frame base 2, and the output shaft of the driving device is fixed to the slider to push the slider to slide in the slide groove 201.

[0044] In the lifting unit at the top, the end of the telescopic part 502 at the top of the telescopic rod 501 is slidably connected to the bottom of the lifting platform 6, and the sliding connection structure is a dovetail groove structure. The top of the second rod 402 is slidably connected to the bottom of the lifting platform 6, and the sliding connection structure is a dovetail groove structure. The top of the first rod 401 is hinged to the lifting platform 6.

[0045] The lifting controller 3 is fixedly arranged on the frame base 2, and the lifting controller 3 includes a control device, which can control the synchronous extension and retraction of the telescopic part 502 on the telescopic rod 501 and the extension and retraction of the driving device, and synchronize the lifting and lowering rate of the telescopic part 502 with the lifting and lowering rate of the corresponding scissors structure, so that the lifting bracket 4 and the telescopic mechanism 5 are lifted and lowered synchronously, thereby realizing the lifting and lowering of the lifting platform 6, and switching the portable vehicle between the traveling state (when lowering the height) and the working state (when raising the height).

[0046] The lifting controller 3 also includes a power source. The corresponding power source is selected according to the structure of the telescopic part and the driving device. If the telescopic part adopts a multi-stage electric push rod, the driving device selects an ordinary electric push rod, and the power source is a battery. By controlling the speed of the multi-stage electric push rod and the ordinary electric push rod, the lifting bracket 4 and the telescopic mechanism 5 are lifted and lowered synchronously; if the telescopic part adopts a multi-stage hydraulic cylinder, the driving device selects an ordinary hydraulic cylinder, and the power source is a hydraulic system. The speed of the multi-stage hydraulic cylinder and the ordinary hydraulic cylinder is controlled by a valve, so that the lifting bracket 4 and the telescopic mechanism 5 are lifted and lowered synchronously. The lifting controllers 3 on both sides of the lifting platform 6 are equipped with wireless communication modules, so that the lifting controllers 3 on both sides act synchronously, thereby ensuring that the lifting platform 6 can be lifted and lowered normally.

[0047] When the present invention adopts a multi-stage electric push rod or a common electric push rod, a self-locking mechanism is arranged thereon, and when a multi-stage hydraulic cylinder or a common hydraulic cylinder is adopted, a valve is used for locking to prevent the lifting platform 6 from sliding down during operation.

[0048] While the lifting bracket 4 and the telescopic mechanism 5 are controlled synchronously, two sets of driving devices are used to drive them separately. When one of the driving devices of the lifting bracket 4 or the telescopic mechanism 5 malfunctions and cannot be lifted or lowered, the other can drive the abnormal component to lift or lower synchronously, and the lifting controller 3 will give an alarm to indicate the abnormality to ensure safety and reliability.

[0049] Since the portable vehicle of the present invention needs to straddle the blade root, the two sets of lifting mechanisms are respectively arranged on both sides of the bottom of the lifting platform 6, so that the two sets of lifting mechanisms are arranged separately and the two sets of lifting mechanisms are kept synchronously lifted through the wireless communication module to ensure that the lifting process of the portable vehicle is stable.

[0050] Each lifting unit is provided with two folding pedals 15, which are respectively located on the upper and lower sides of the hinged position of the first rod 401 and the second rod 402 in the lifting unit and are parallel to each other, and the folding pedals 15 of each lifting unit are evenly distributed in the vertical direction. The folding pedals 15 are connected to the lifting unit through the pedal fixing rod 14, and the fixing method of each pedal fixing rod 14 is the same as that of the lifting unit. The pedal fixing rod 14 below the middle lifting unit is used as an example for explanation. A pin hole 1401 is provided at one end of the pedal fixing rod 14, and a long hole 1402 is provided at the other end. The pin hole 1401 is rotatably connected to the second pin shaft 404 on the first rod 401, and the long hole 1402 is slidably connected to the third pin shaft 405 on the second rod 402. The pin holes 1401 of the pedal fixing rods 14 distributed in the upper and lower directions are all located on the same side of the telescopic mechanism 5, and the long hole 1402 is located on the other side of the telescopic mechanism 5. When the lifting bracket 4 and the telescopic mechanism 5 are in a retracted state (the height of the portable cart is reduced to the lowest), the third pin shaft 405 is located at the end of the long hole away from the telescopic mechanism 5; when the lifting bracket 4 and the telescopic mechanism 5 are in an extended state (the height of the portable cart is raised to the highest), the third pin shaft 405 is located at the end of the long hole close to the telescopic mechanism 5.

[0051] The folding pedal 15 is arranged on the pedal fixing rod 14. When the portable car is in a contracted state, the folding pedal 15 is folded up. When the portable car is in an extended state, the folding pedal 15 is unfolded to facilitate the operator to climb. In other embodiments, the folding pedal 15 may also be replaced by a common pedal.

[0052] The pedal is arranged on the lifting bracket 4 through the pedal fixing structure 14, and can be contracted or extended synchronously with the lifting bracket 4 while avoiding interference. There is no need to open the pedal after the lifting bracket 4 is opened, which saves the time of deployment and improves work efficiency.

[0053] The operating platform 9 is slidably arranged on the lifting platform 6. In this embodiment, a rack 8 extending in the sliding direction can be nested on the upper surface of the lifting platform 6. A gear 18 driven by a motor is arranged at the bottom of the operating platform 9. The gear 18 is meshed with the rack 8. The rotation of the motor drives the gear 18 to rotate, so that the operating platform 9 slides on the lifting platform 6. In order to expand the moving range of the operating platform 9 in the sliding direction, thereby expanding the operating range and installing more parts, a plurality of gears 18 are distributed at the bottom of the operating platform 9 in the sliding direction. When the operating platform 9 extends backward or forward from the lifting platform 6, as shown in FIG. Figure 3 to Figure 4 , there is still a gear that can mesh with the rack 8 to ensure normal operation. In this embodiment, multiple gears 18 are connected to the same motor through a transmission structure. In other embodiments, other driving structures can also be used to make the operating platform 9 slide on the lifting platform 6. For example, the operating platform 9 can be set on a slider driven by a screw mechanism, and the screw mechanism is set on the lifting platform 6.

[0054] A guardrail 12 is provided on the operating platform 9. In this embodiment, the guardrail 12 is provided on the operating platform 9 through four columns 1201. The guardrail 12 and the columns 1201 surround half of the operating platform 9, and the other half is not provided with the guardrail 12 and the columns 1201, so that the assembler can operate on the operating platform 9 conveniently. A pull rod 13 is provided on one side of the guardrail 12.

[0055] Two columns 1201 are respectively arranged on both sides of the operating platform 9 in the direction of travel. A retractable fixed buckle 10 is arranged at the bottom of the column 1201. The fixed buckle 10 can extend out of the bottom surface of the column 1201. In this embodiment, a buckle electric push rod can be arranged inside the column 1201. The output shaft of the buckle electric push rod is connected to the fixed buckle 10 to control the extension and retraction of the fixed buckle 10. There is a groove 7 on the lifting platform 6 that can match the fixed buckle 10. In this embodiment, three grooves 7 are distributed on the track where the fixed buckle 10 slides on the same side. When the operating platform 9 moves to the desired position, the fixed buckle 10 can be extended and inserted into the groove 7, so that the operating platform 9 and the lifting platform 6 are locked and fixed, and the lifting platform 6 and the operating platform 9 are connected and tightened. In this embodiment, since two fixing buckles 10 are arranged on the same side and correspond to three grooves 7, when one of the fixing buckles 10 is inserted into one of the grooves 7, the fixation between the operating platform 9 and the lifting platform 6 can be achieved. Therefore, the operating platform 9 can be set at 6 positions of the lifting platform 6 in the sliding direction.

[0056] A sliding controller 11 is provided on the operating platform 9 , and the sliding controller 11 controls the motor and the snap-on electric push rod, so that the operating platform 9 slides and is fixed on the lifting platform 6 .

[0057] In this embodiment, the operating platform 9 and the lifting platform 6 are slidably connected by a dovetail groove structure 16, so that the operating platform 9 can be extended out of the lifting platform 6 while being fixed and stable. After the lifting platform 6 is raised, the operating platform 9 is extended out of the lifting platform 6 and fixed by the fixing buckle 10, thereby expanding the operating space while ensuring safety. Figure 3 to Figure 4 shown.

[0058] After the operating platform 9 and the lifting platform 6 are locked and fixed by the fixing buckle 10 and the groove 7, the lifting platform 6 is lowered to a height that the operator can push and pull, and then the telescopic mechanism 5 and the lifting bracket 4 are automatically locked. Pulling the pull rod 13 can push the trolley to move as a whole, and the operation is simple.

[0059] The portable trolley for assembling wind farm blade components of the present invention is used for the installation of a rainproof ring cover as an example to illustrate as follows: Figures 7 and 8As shown, push the portable trolley to the position of the blade root, fix and lock the universal wheel 1; operate the lifting controller 3, raise the telescopic mechanism 5 and the lifting bracket 4, raise the lifting platform 6 to the required height, and fix and lock the telescopic mechanism 5 and the lifting bracket 4; mobilize the sliding controller 11, move the operating platform 9 to the required position, align the fixed buckle 10 with the groove 7 on the lifting platform 6, extend the fixed buckle 10 and insert it into the groove 7 to achieve fixed locking; the high-altitude operator fixes the safety rope to the guardrail (fixed beam for high-altitude operation) 12, and the high-altitude operator installs the blade rainproof ring cover 17 on the operating platform 9. The present invention can also be used for blade root bolt installation and replacement, VG installation, monitoring system assembly, blade external damage repair, etc., suitable for a variety of operation needs, flexible and convenient.

[0060] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
