Description

Technical Field

[0001] This invention relates to the field of wind power product transportation technology, and more specifically, to a split-type transportation tool. Background Technology

[0002] Wind turbine blade transport fixtures are devices used to fix and transport wind turbine blades. The transport fixtures ensure the stability of the blades during transportation and prevent damage caused by the blades swinging during transport.

[0003] Existing wind turbine blade transport fixtures are diverse. For example, Chinese utility model patent CN218786007U discloses a wind turbine blade transfer fixture. This fixture is used to fix wind turbine blades for easy transport. The transfer fixture includes a base plate and several lower clamping components located at the top of the base plate. A first cylinder is mounted on the base plate, and a second cylinder is mounted at the other end of the base plate. A top plate is mounted above the first and second cylinders. The piston end of the first cylinder is hinged to the bottom end of the top plate, and a support plate is mounted on the piston end of the second cylinder to support... The top of the plate contacts the bottom of the top plate. The right end of the top plate is detachably connected to the support plate and locked in place by a fastener. A detachable upper clamping assembly is provided at the bottom of the top plate. The upper clamping assembly and the lower clamping assembly are set one-to-one. During the transportation of wind power products, the top plate is first opened by the fastener, then the wind turbine blades are placed on the lower clamping assembly, and then the top plate is locked in place by the fastener. The height of the first cylinder and the second cylinder are adjusted so that the upper clamping assembly and the lower clamping assembly cooperate to fix the wind turbine blades, so as to facilitate the transportation of the wind turbine blades.

[0004] Although the aforementioned transfer fixture can fix wind turbine blades, in actual use, relying solely on the cooperation of the upper and lower clamping components to clamp and fix the wind turbine blades is insufficient to achieve the desired effect, thus creating certain obstacles for the transportation of wind turbine blades.

[0005] Therefore, the present invention provides a split-type transport fixture for fixing wind turbine blades during transport, so as to facilitate the transport of wind turbine blades. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the invention, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0007] To address the technical problem of poor stability of wind turbine blades during transportation in existing technologies, the present invention adopts the following technical solution.

[0008] A split-type transport fixture is composed of opposing frame units. The opposing frame units support wind power products, and clamping units are provided on the frame units to clamp the wind power products. The clamping units are composed of a lower clamping component and an upper clamping component. The lower clamping component includes a lower shell, and the upper clamping component includes an upper shell. The upper shell and the lower shell are opposite to each other, and clamping grooves are opened on the opposite surfaces. The lower shell and the upper shell move towards each other and clamp and fix the wind power products through the clamping grooves.

[0009] Preferably, in the above-mentioned transport fixture, guide blocks are fixedly installed on both sides of the top of the lower shell, and a guide groove is provided on the upper shell at a position relative to the guide blocks. When the upper shell and the lower shell move towards each other, the guide blocks slide in the guide groove.

[0010] Preferably, in the above-mentioned transport fixture, the lower housing is further connected to a guide rod, and the upper housing is provided with a guide hole at a position relative to the guide rod. When the upper housing and the lower housing move towards each other, the guide rod moves in the guide hole. An elastic element is sleeved on the guide rod, and the elastic element is used to buffer the relative movement of the upper housing and the lower housing.

[0011] Preferably, in the above-mentioned transport fixture, the upper housing is further provided with an adjusting screw, which is threadedly assembled with the lower housing. By driving the adjusting screw to rotate, the upper housing and the lower housing can be driven to move towards each other.

[0012] Preferably, in the above-mentioned transport fixture, the upper shell and the lower shell are provided with multiple clamping grooves, and the number and position of the clamping grooves correspond one-to-one.

[0013] Preferably, in the above-mentioned transport fixture, the clamping groove is further provided with an opening groove, and the upper shell and the lower shell are further provided with a pressure plate, which can move through the opening groove and enter the clamping groove within the upper shell and the lower shell.

[0014] Preferably, in the above-mentioned transport fixture, the lower shell and the upper shell are further provided with an adaptive component. The adaptive component includes a pressure chamber and an adjustment chamber. The pressure chamber and the adjustment chamber are connected by a pipe. A piston plate I is provided in the pressure chamber. The adaptive component also includes an abutment rod that extends into the pressure chamber and connects with the piston plate I. A piston plate II is provided in the adjustment chamber. The pressure plate is located outside the adjustment chamber and is connected to the piston plate II.

[0015] Preferably, in the above-mentioned transport fixture, the pressure chamber is further provided with a spring I, one end of which is connected to the inner wall of the pressure chamber, and the other end is connected to the piston plate I.

[0016] Preferably, in the above-mentioned transport fixture, a spring II is provided inside the adjustment chamber, with one end of the spring II connected to the piston plate II and the other end connected to the inner wall of the adjustment chamber.

[0017] Preferably, in the above-mentioned transport fixture, the length of the abutment rod is adjustable. The length of the abutment rod is composed of a movable rod and a threaded rod. The movable rod is slidably assembled with the pressure chamber, and the threaded rod is threadedly assembled in the movable rod. Rotating the threaded rod causes the threaded rod to screw into or out of the movable rod to adjust the length of the abutment rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The transport fixture in this invention includes opposing frame units, and a clamping unit is provided on the frame unit. The two ends of the wind turbine blade are placed on the frame unit, and the wind turbine blade is clamped by the clamping unit on the frame unit. Therefore, the clamping unit can ensure the stability of the wind turbine blade on the frame unit, so as to facilitate the transport of the wind turbine blade.

[0020] The clamping unit in this invention includes an upper clamping assembly and a lower clamping assembly. The upper clamping assembly includes an upper housing, and the lower clamping assembly includes a lower housing. Clamping grooves are provided on the opposite surfaces of the upper and lower housings. The clamping action of the clamping grooves clamps and fixes the wind turbine blades, ensuring the stability of the wind turbine blades. In addition, the upper and lower housings are guided to move by guide blocks and guide rods, avoiding the problem of misalignment between the upper and lower housings. The guide rods are also provided with elastic elements to buffer the movement of the upper and lower housings, avoiding the problem of rigid contact between the upper and lower housings causing scratches or even damage to the wind turbine blades.

[0021] The upper and lower housings of this invention are further equipped with an adaptive component. The adaptive component includes a pressure chamber and an adjustment chamber disposed within the upper and lower housings. Both the pressure chamber and the adjustment chamber are equipped with piston plates. The adaptive component also includes an abutment rod and a pressure plate. The abutment rod is connected to the piston plate in the pressure chamber, and the pressure plate is connected to the piston plate in the adjustment chamber. When the upper and lower housings move towards each other and the abutment rod contacts, the gas in the pressure chamber is driven into the adjustment chamber, thereby driving the pressure plate to move. The clamping groove is provided with an opening slot, through which the pressure plate can enter the clamping groove. Therefore, the adaptive component can simultaneously clamp and fix multiple wind turbine blades of different sizes, ensuring the effectiveness of the transport tooling. Attached Figure Description

[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0041] Example 1

[0042] like Figure 1 as well as Figure 2 As shown, this is a schematic diagram of the split-type transport fixture in this embodiment. The transport fixture in this embodiment is composed of opposing frame units A. In this embodiment, the frame units A are positioned opposite each other, and the two ends of the wind turbine blades are respectively placed on the frame units A. The opposing frame units A are used to support the wind turbine blades, and as shown... Figure 1 as well as Figure 2 As shown in this embodiment, a clamping unit B is also provided on the opposite side of the frame unit A. After the two ends of the wind turbine blade are placed on the frame unit A, the clamping unit B clamps the two ends of the wind turbine blade, thereby ensuring the stability of the wind turbine blade and facilitating its transportation.

[0043] like Figures 3-5 As shown, this is a structural schematic diagram of the clamping unit B in this embodiment. The clamping unit B in this embodiment is composed of a lower clamping component 100 and an upper clamping component 200 arranged opposite to each other. In this embodiment, the lower clamping component 100 includes a lower housing 101, and the upper clamping component 200 includes an upper housing 201. The lower housing 101 and the upper housing 201 are provided with clamping grooves on opposite sides, and the number and position of the clamping grooves correspond one-to-one. When the clamping unit B clamps the wind turbine blade, the upper housing 201 and the lower housing 101 move relative to each other and clamp and fix the wind turbine blade through the clamping grooves, thereby ensuring the stability of the wind turbine blade on the frame unit A, so as to facilitate the transportation of the wind turbine blade.

[0044] like Figures 3-5 As shown, in this embodiment, guide blocks 103 are fixedly installed on both sides of the top of the lower housing 101, and a guide groove is provided on the upper housing 201 at a position relative to the guide blocks 103. When the upper housing 201 and the lower housing 101 move towards each other, the guide blocks 103 slide in the guide groove. In addition, in this embodiment, a guide rod 102 is also connected to the lower housing 101, and a guide hole is provided on the upper housing 201 at a position relative to the guide rod 102. When the upper housing 201 and the lower housing 101 move towards each other, the guide rod 102 moves in the guide hole, and as shown... Figure 3 as well as Figure 5As shown, in this embodiment, an elastic element is sleeved on the guide rod 102. The elastic element is used to buffer the relative movement of the upper housing 201 and the lower housing 101, so as to avoid the problem of the wind turbine blade being scratched or damaged due to rigid collision between the upper housing 201 and the lower housing 101 and the wind turbine blade when clamping the wind turbine blade.

[0045] The guide block 103 and guide rod 102 in this embodiment can ensure the linear movement of the upper housing 201 and the lower housing 101, so that the guide grooves of the upper housing 201 and the lower housing 101 can cooperate with each other to clamp and fix the wind turbine blade.

[0046] like Figure 5 As shown, in this embodiment, an adjusting screw 202 is also provided on the upper housing 201. The adjusting screw 202 is threadedly assembled with the lower housing 101. Therefore, when it is necessary to drive the upper housing 201 and the lower housing 101 to move towards each other, the adjusting screw 202 is driven to rotate, thus driving the upper housing 201 and the lower housing 101 to move towards each other. It should also be noted that in this embodiment, the clamping unit B is installed on the frame unit A. Specifically, the lower clamping component 100 in the clamping unit B is installed on the frame unit A, and the upper clamping component 200 does not contact the frame unit A. This ensures that the upper clamping component 200 can move freely, so as to adjust the distance between the upper clamping component 200 and the lower clamping component 100, thus enabling the clamping of wind turbine blades.

[0047] In this embodiment, the two ends of the wind turbine blade are respectively supported on the frame unit A, and the clamping unit B on the frame unit A can clamp the wind turbine blade. Therefore, the transport fixture in this embodiment can ensure the stable clamping effect of the wind turbine blade during the transport process, so as to facilitate the transport of the wind turbine blade.

[0048] Example 2

[0049] like Figures 5-8 As shown, this is a schematic diagram of the structure of clamping unit B in the transport fixture in this embodiment. Multiple wind turbine blades need to be transported simultaneously during the transport process. When the size of the wind turbine blades is not uniform, it is difficult to achieve clamping of multiple wind turbine blades of different sizes by the same clamping unit B. In order to solve this problem, this embodiment provides the following clamping solution.

[0050] The clamping unit B in this embodiment is based on embodiment 1, such as... Figure 5 as well as Figure 6As shown, an opening slot 101a is provided in the clamping groove of the lower housing 101 and the upper housing 201, and an adaptive component 300 is provided inside the lower housing 101 and the upper housing 201. The adaptive component 300 includes a pressure plate 304 disposed inside the upper housing 201 and the lower housing 101. The number and position of the pressure plate 304 correspond one-to-one with the opening slots. The pressure plate 304 can move within the upper housing 201 and the lower housing 101 and enter the clamping groove through the opening slot 101a, thereby clamping and fixing the wind turbine blades in the clamping groove. Figure 7 as well as Figure 8 As shown, this is a structural schematic diagram of the adaptive component 300 in this embodiment. The adaptive component 300 in this embodiment also includes a pressure chamber 301 and an adjustment chamber 302 disposed within the lower housing 101 and the upper housing 201. In this embodiment, the pressure chamber 301 and the adjustment chamber 302 are connected by pipes, as shown... Figure 7 As shown, the regulating chamber 302 is provided with an abutment rod 303, which extends to the outside of the lower shell 101 and the upper shell 201, and the positions of the abutment rods 303 are opposite to each other. In this embodiment, when the upper shell 201 and the lower shell 101 move towards each other, after the abutment rods 303 abut, the upper shell 201 and the lower shell 101 continue to move towards each other. The pressure chamber 301 is provided with a piston plate I 301a, as shown. Figure 9 As shown, the abutment rod 303 is connected to the piston plate I 301a. When the upper housing 201 and the lower housing 101 continue to move towards each other, the abutment rod 303 drives the piston plate I 301a to move within the pressure chamber 301, thereby driving the gas in the pressure chamber 301 to enter the regulating chamber 302 through the pipe. Figure 10 As shown, in this embodiment, the regulating chamber 302 is provided with a piston plate II 302a, and the pressure plate 304 is connected to the piston plate II 302a. When the pressure in the space at the bottom of the piston plate II 302a in the pressure chamber 302 increases, the pressure plate 304 moves upward and enters the clamping groove through the opening slot 101a to clamp the wind turbine blades in the clamping groove. Since the size of the wind turbine blades in the clamping groove is not uniform, the pressure plate 304 cannot pass through the opening slot 101a to enter the clamping groove after the larger wind turbine blades are clamped in the clamping groove due to the obstruction of the wind turbine blades. Therefore, the pressure plate 304 passes through the opening slot 101a to enter the clamping groove due to the pressure of the smaller wind turbine blades in the other clamping grooves to clamp and fix the smaller wind turbine blades.

[0051] In addition, such as Figure 9 as well as Figure 10As shown, in this embodiment, a spring I 301b is also provided in the pressure chamber 301. One end of the spring I 301b is connected to the inner wall of the pressure chamber 301, and the other end is connected to the piston plate I 301a. A spring II 302b is provided in the adjustment chamber 302. One end of the spring II 302b is connected to the piston plate II 302a, and the other end is connected to the inner wall of the adjustment chamber 302. Therefore, when the wind turbine blade is released from clamping, the piston plate I 301a and the piston plate II 302a can be reset by the spring I 301b and the spring II 302b, thereby realizing the reset of the pressure plate 304 and its entry into the lower housing 101 and the upper housing 201 respectively.

[0052] In addition, such as Figure 9 As shown, in this embodiment, the adaptive component 300 clamps the wind turbine blade through pressure adaptation; the greater the pressure, the more stable the clamping effect. To increase the pressure in the pressure chamber 301 and the regulating chamber 302 when clamping the wind turbine blade, the length of the abutment rod 303 in this embodiment is adjustable. Figure 9 As shown, the length of the abutment rod 303 is composed of a movable rod 303a and a threaded rod 303b. The movable rod 303a is slidably assembled with the pressure chamber 301, and the threaded rod 303b is threadedly assembled in the movable rod 303a. Rotating the threaded rod 303b causes it to screw into or out of the movable rod 303a, thus adjusting the length of the abutment rod 303. When the upper housing 201 and the lower housing 101 move towards each other, the pressure inside the pressure chamber 301 and the adjustment chamber 302 increases due to the longer length of the abutment rod 303, ensuring the clamping effect on the wind turbine blade and ensuring the stability of the wind turbine blade.

[0053] In this embodiment, the adaptive component 300 enables the pressure plate 304 to pass through the opening slot 101a and enter the clamping slot, thereby enabling the synchronous clamping of multiple wind turbine blades of different sizes, ensuring their stability, and facilitating the transportation of wind turbine blades.

[0054] The above is the technical solution of the transport fixture in this invention. The wind turbine blades are supported by the separately set frame unit A, and the clamping unit B on the frame unit A clamps the wind turbine blades, thereby ensuring the stability of the wind turbine blades. In addition, the adaptive component 300 in the clamping unit B allows the clamping unit B to clamp multiple wind turbine blades of different sizes simultaneously by adjusting the pressure. This avoids the limitation that each size of wind turbine blade needs to be clamped by its matching clamping unit B, thereby improving the transport efficiency of the wind turbine blades and the practicality of the transport fixture, and ensuring the transport efficiency of the wind turbine blades.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
