Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation blade transport semi-trailers, in particular to a wind power generation blade transport semi-trailer with a locking mechanism. Background Art

[0002] Wind turbine blades are a crucial component of wind turbines. Their primary function is to capture wind energy and convert it into mechanical energy, thereby driving the generator to generate electricity. In mountain wind farms, due to the large size and length of wind turbine blades, a locking mechanism is often used to secure the blades to the semi-trailer, ensuring safe and efficient transportation to the designated location.

[0003] After searching, the Chinese patent "A special blade fixing device for wind power construction" with authorization announcement number "CN219774269U" realizes the locking of wind turbine blades on the semi-trailer through screws, nuts and fixing plates, ensuring that the wind turbine blades are stably installed on the semi-trailer.

[0004] In the above application, the semi-trailer will generate a large vibration force during mountain transportation, which will be transmitted to the nut, which may easily cause the nut to loosen on the screw, thereby affecting the stability of the wind turbine blades transported by the semi-trailer.

[0005] Therefore, a wind turbine blade transport trailer with a locking mechanism is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a wind turbine blade transport semi-trailer with a locking mechanism in order to solve the above-mentioned problem, thereby improving the problem that the trailer will generate large vibration force transmitted to the nut during mountain transportation, which may easily cause the nut to loosen on the screw.

[0007] The utility model achieves the above-mentioned object through the following technical solutions: a wind turbine blade transport semi-trailer with a locking mechanism, comprising: a fixed plate, the top end of which is rotatably connected to a mounting plate, the top end of which is hinged to a locking frame, and one side of the locking frame is provided with an annularly distributed nut; an anti-loosening mechanism, the anti-loosening mechanism being arranged on the surface of the locking frame; wherein the anti-loosening mechanism comprises two interference blocks slidably connected to one side of the locking frame, one end of the interference block is fixedly connected to an anti-slip pad, the inner wall of the locking frame is rotatably connected to a bidirectional screw rod, the inner wall of the interference block is threadedly connected to the surface of the bidirectional screw rod, the upper end of the inner wall of the locking frame is fixedly connected to a first servo motor, the output shaft of the first servo motor is fixedly connected to the top end of the bidirectional screw rod, the inner wall of the locking frame is slidably connected to two positioning brackets, the surface of the positioning bracket is clamped to the inner wall of the interference block, the surface of the positioning bracket is fixedly connected to a spring, and the other end of the spring is fixedly connected to the inner wall of the locking frame. Through the bidirectional screw, servo motor and resistance block, the anti-slip pad is pressed against one end of the nut, and the resistance block is locked by the spring and the positioning frame, ensuring that the anti-slip pad stably limits the movement of the nut. Compared with the existing nut that is prone to loosening at the screw on the wind turbine blade after being vibrated, this method limits the movement range of the nut, thereby preventing the nut from being displaced at the screw, and ensuring the stability of the wind turbine blade transported by the semi-trailer.

[0008] Preferably, a circularly distributed limit frame is fixedly connected to one side of the locking frame, a roller is rotatably connected to the inner wall of the limit frame, a connecting frame is slidably connected to the inner wall of the locking frame, and a guide cylinder is fixedly connected to the front end of the connecting frame. The limit frame and the roller are used to achieve preliminary guidance of the wind turbine blade, thereby avoiding a large gap caused by the screw on the wind turbine blade and the reserved hole on the locking frame not being at the same center of a circle. The guide cylinder is used to guide one of the screws on the wind turbine blade, so that multiple screws on the wind turbine blade can be accurately and quickly inserted into the reserved hole on the locking frame, thereby improving the convenience of locking the wind turbine blade on the semi-trailer. The connecting frame is used to achieve movement of the wind turbine blade toward the locking frame after alignment, so that the guide cylinder and the connecting frame are pushed to the inner wall of the locking frame, thereby avoiding the protrusion of the guide cylinder affecting the locking operation of the wind turbine blade.

[0009] Preferably, two support blocks are fixedly connected to the ends of the limit frame, one side of each support block being fixedly connected to one side of the locking frame. The support blocks form a stable triangular fulcrum between the limit frame and the locking frame, thereby strengthening the support of the limit frame and ensuring that the limit frame and the guide cylinder stably support and limit the wind turbine blades.

[0010] Preferably, the top of the support block forms an angle with the horizontal plane.

[0011] Preferably, a magnetic block is embedded in the lower end of the surface of the locking frame, and the positioning frame is an iron-cobalt alloy component. The surface of the magnetic block is magnetically attracted to the surface of the positioning frame. The magnetic block ensures that the positioning frame is stably engaged in the interference block.

[0012] Preferably, a stop pad is fixedly connected to one side of the positioning frame, and one side of the stop pad is tightly attached to the lower end of the surface of the locking frame.

[0013] Preferably, a corrugated rubber sleeve is fixedly connected to both the top and bottom of the interference block, with the end of the corrugated rubber sleeve on one side, away from the interference block, fixedly connected to the inner wall of the locking frame. The corrugated rubber sleeve seals the opening on one side of the locking frame, preventing dust from adhering to the surface of the bidirectional screw and reducing wear between the bidirectional screw and the interference block.

[0014] The beneficial effects of the utility model are:

[0015] 1. The anti-slip pad is pressed against one end of the nut by a bidirectional screw, a servo motor, and a resistance block. The resistance block is locked by a spring and a positioning frame, ensuring that the anti-slip pad is stable and restricts the movement of the nut. Compared with existing nuts that are prone to loosening at the screw on the wind turbine blade after being subjected to vibration, this method limits the movement range of the nut, thereby preventing the nut from shifting at the screw, ensuring the stability of the wind turbine blade when transported by a semi-trailer;

[0016] 2. The limit frame and the roller are used to initially guide the wind turbine blades, thereby avoiding a large gap caused by the screws on the wind turbine blades and the reserved holes on the locking frame not being at the same center of a circle. The guide cylinder is used to guide one of the screws on the wind turbine blades, so that multiple screws on the wind turbine blades can be accurately and quickly inserted through the reserved holes on the locking frame, thereby improving the convenience of locking the wind turbine blades on the semi-trailer. The connecting frame is used to move the wind turbine blades toward the locking frame after alignment, so that the guide cylinder and the connecting frame are pushed to the inner wall of the locking frame, thereby avoiding the protrusion of the guide cylinder affecting the locking operation of the wind turbine blades.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] When implementing: Figure 1-4 As shown, a wind turbine blade transport semi-trailer with a locking mechanism comprises: a fixing plate 1, the top of the fixing plate 1 is rotatably connected to a mounting plate 2, the top of the mounting plate 2 is hinged to a locking frame 4, and one side of the locking frame 4 is provided with a ring-shaped nut 3; an anti-loosening mechanism 5, the anti-loosening mechanism 5 is arranged on the surface of the locking frame 4; wherein the anti-loosening mechanism 5 comprises two resistance blocks 51 slidably connected to one side of the locking frame 4, one end of the resistance block 51 is fixedly connected to an anti-slip pad 52, and the inner wall of the locking frame 4 is rotatably connected to the fixing plate 1. It is connected to a bidirectional screw rod 53, the inner wall of the resistance block 51 is threadedly connected to the surface of the bidirectional screw rod 53, the upper end of the inner wall of the locking frame 4 is fixedly connected to the first servo motor 54, the output shaft of the first servo motor 54 is fixedly connected to the top of the bidirectional screw rod 53, and the inner wall of the locking frame 4 is slidably connected to two positioning frames 55, the surface of the positioning frame 55 is clamped to the inner wall of the resistance block 51, and the surface of the positioning frame 55 is fixedly connected to a spring 56, and the other end of the spring 56 is fixedly connected to the inner wall of the locking frame 4.

[0024] The bottom end of the fixed plate 1 is mounted on the frame of the semi-trailer, and the top of the mounting plate 2 is hinged with two hydraulic cylinders, and the top of the hydraulic cylinder is hinged to one side of the locking frame 4. The inner wall of the fixed plate 1 is fixedly connected to the second servo motor, and the output shaft of the second servo motor is fixedly connected to the first gear. The lower end of the surface of the mounting plate 2 is fixedly connected to the second gear, and the first gear is meshed with the second gear. The diameter of the second gear is larger than the diameter of the first gear. The specific gear diameter ratio can be selected according to actual needs. A ring-shaped screw is installed at one end of the wind turbine blade, and the anti-slip pad 52 is a rubber component.

[0025] After the wind turbine blades need to be transported to the designated location, the wind turbine blades are lifted by using a crane and aligned with the reserved holes on the locking frame 4. The wind turbine blades are lifted and moved so that the multiple screws at the ends of the wind turbine blades are inserted through the reserved holes on the locking frame 4, and the ends of the wind turbine blades are pressed against one side of the locking frame 4. The wind turbine blades are stopped from moving, and an electric wrench is used to thread the multiple nuts 3 one by one on the multiple screws so that one end of the nut 3 is pressed against one side of the locking frame 4. The first servo motor 54 is manually turned on, and the output shaft of the first servo motor 54 rotates to drive the bidirectional screw rod 53 to rotate, and the rotation of the bidirectional screw rod 53 drives the two contact blocks 51 to approach each other. The movement of the resistance block 51 drives the anti-skid pad 52 to move and resist the end of the nut 3. When the two resistance blocks 51 are in contact, the first servo motor 54 is manually turned off, and the elastic force of the spring 56 pushes the positioning frame 55 to move and snap into the resistance block 51, so that the two anti-skid pads 52 stably resist the end of the nut 3, so that the wind turbine blade is locked in the locking frame 4. At this time, the hydraulic cylinder is manually opened, and the top end of the hydraulic cylinder moves to drive the locking frame 4 to adjust the angle to the appropriate position on the mounting plate 2. The hydraulic cylinder is manually closed. At this time, the driver transports the wind turbine blade to the designated location by starting the semi-trailer. During transportation, due to the limitation of the nut 3, the wind turbine blade is firmly fixed on the locking frame 4.

[0026] like Figure 2 and Figure 4 As shown, one side of the locking frame 4 is fixedly connected to a ring-shaped limit frame 510, the inner wall of the limit frame 510 is rotatably connected to a roller 511, the inner wall of the locking frame 4 is slidably connected to a connecting frame 59, the front end of the connecting frame 59 is fixedly connected to a guide cylinder 58, and the end of the limit frame 510 is fixedly connected to two support blocks 512, one side of the support block 512 is fixedly connected to one side of the locking frame 4, and the top of the support block 512 forms an angle with the horizontal plane.

[0027] In the initial state, the guide cylinder 58 slides out of the inner wall of the locking frame 4. The wind turbine blade is lifted by a crane and moved toward one side of the locking frame 4. The surface of the wind turbine blade contacts the roller 511. The roller 511 guides the moving wind turbine blade. At this time, the wind turbine blade is pushed so that one of the screws on it is aligned with the guide cylinder 58. The wind turbine blade continues to move so that one of the screws passes through the inner wall of the guide cylinder 58. After the end of the guide cylinder 58 contacts the end of the wind turbine blade, the guide cylinder 58 is pushed into the inner wall of the locking frame 4 and multiple screws are accurately inserted through the reserved holes on the locking frame 4.

[0028] like Figure 4As shown, a magnetic block 57 is embedded and installed at the lower end of the surface of the locking frame 4, and the positioning frame 55 is an iron-cobalt alloy component. The surface of the magnetic block 57 is magnetically attracted to the surface of the positioning frame 55, and a stop pad 513 is fixedly connected to one side of the positioning frame 55, and one side of the stop pad 513 is tightly attached to the lower end of the surface of the locking frame 4.

[0029] like Figure 3 As shown, the top and bottom of the interference block 51 are fixedly connected to the corrugated rubber sleeve 514 , wherein the end of the corrugated rubber sleeve 514 on one side away from the interference block 51 is fixedly connected to the inner wall of the locking frame 4 .

[0030] When the utility model is in use, the wind turbine blade is lifted by using a crane and moved toward one side of the locking frame 4. The surface of the wind turbine blade contacts the roller 511, and the roller 511 guides the moving wind turbine blade. At this time, the wind turbine blade is pushed so that one of the screws is aligned with the guide cylinder 58. The wind turbine blade continues to move so that one of the screws penetrates the inner wall of the guide cylinder 58. The guide cylinder 58 is pushed into the inner wall of the locking frame 4 and multiple screws are accurately penetrated through the reserved holes on the locking frame 4, so that the end of the wind turbine blade contacts one side of the locking frame 4. An electric wrench is used to thread the multiple nuts 3 one by one and install them in the multiple screws. On the screw, one end of the nut 3 is in contact with one side of the locking frame 4, and the first servo motor 54 is manually turned on. The output shaft of the first servo motor 54 rotates to drive the bidirectional screw rod 53 to rotate. The rotation of the bidirectional screw rod 53 drives the two contact blocks 51 to approach each other. The movement of the contact block 51 drives the anti-slip pad 52 to move and contact the end of the nut 3. When the two contact blocks 51 are in contact, the first servo motor 54 is manually turned off, and the elastic force of the spring 56 pushes the positioning frame 55 to move and snap into the contact block 51. The positioning frame 55 is adsorbed on the magnetic block 57, so that the two anti-slip pads 52 stably contact the end of the nut 3, so that the wind turbine blade is locked in the locking frame 4.

[0031] It should be noted that the fixed plate 1, mounting plate 2, nut 3, first servo motor 54, second servo motor, bidirectional screw rod 53, magnetic block 57 and spring 56 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the power supply for the first servo motor 54 and the second servo motor can be a built-in power supply or a mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0032] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
