Description

Technical Field

[0001] The utility model relates to the field of brackets, and particularly relates to a clamping plate type blade transportation bracket. Background Art

[0002] With the continuous increase in the global demand for renewable energy, the continuous progress of wind power technology and the expansion of the market scale, the demand for wind turbine blades will continue to grow. Wind turbine blades are an important part of wind turbines and undertake the important task of converting wind energy into electrical energy. The design of the blades directly affects the performance and efficiency of the wind turbines. The working principle of wind turbine blades is based on aerodynamics, and their shape is similar to that of an airplane wing. By capturing wind energy and converting it into rotational energy, the generator is then driven to generate electrical energy.

[0003] The existing Chinese patent authorization publication number: CN217970749U discloses a clamping plate type wind turbine blade transportation bracket, which includes a fixed base. Rectangular support seats are arranged at the left and right edges of the top of the fixed base. A U-shaped movable groove is opened at the top of the rectangular support seat. A movable slider is slidably connected in each of the two U-shaped movable grooves. Moving plates are arranged at the tops of the two movable sliders. A bracket seat is jointly connected to the tops of the two moving plates through support columns. An arc-shaped groove adapted to the wind turbine blade is opened at the top of the bracket seat. For this clamping plate type wind turbine blade transportation bracket, the wind turbine blade can be clamped and fixed through a fixed vertical block, a threaded rod and an arc-shaped pressing plate; when the transport vehicle makes an emergency brake, the two movable sliders slide in the two U-shaped movable grooves respectively, and under the action of four first hydraulic buffers, the two movable sliders can be buffered and decelerated back and forth until they stop, so as to play a role in front-back buffering and avoid damage to the wind turbine blade under the action of inertia.

[0004] The above-mentioned transportation bracket still has the following problems when in use: When the above-mentioned bracket is in use, it is necessary to twist the threaded rod twice to achieve the stable clamping of the two arc-shaped pressing plates on the blade. Twisting twice is rather cumbersome, and there may be a time difference during the two twisting processes (twist one and then twist the other), which may cause the subsequent position of the blade to shift, and the blade is not in the center position of the bracket, affecting the subsequent transportation work.

[0005] Therefore, it is very necessary to invent a clamping plate type blade transportation bracket to solve the above problems. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a clamping plate type blade transportation bracket to solve the problem that the above-mentioned bracket in the background technology requires twisting the threaded rod twice to achieve stable clamping of the blade by the two arc-shaped pressing plates. Twisting twice is rather cumbersome, and there may be a time difference during the two twisting processes (twisting one first and then the other), which may cause the subsequent position of the blade to shift, and the blade is not in the central position of the bracket, affecting the subsequent transportation work.

[0007] To achieve the above purpose, the present utility model provides the following technical solution: A clamping plate type blade transportation bracket includes a frame body.

The chute and the channel are matched, and the acting force applied by the external torsion spring supports the clamping plate.

[0009] Preferably, a "U"-shaped placement groove is arranged in the middle part of the frame body for placing the lower end of the blade.

[0010] Preferably, the cavity is square, and there are two cavities. The two cavities are symmetrically arranged left and right with reference to the vertical central axis of the frame body, and the two cavities are not connected to each other, facilitating the movement of the moving plate and then driving the movement of the clamping plate integrally installed with the moving plate through the connecting short rod.

[0011] Preferably, the screw rod penetrates through the two cavities, and the screw rod is rotatably connected to the through hole arranged inside the frame body through a bearing, ensuring the smooth rotation of the screw rod;

[0012] Two sections of threads are arranged on the outer circle of the screw rod. The two sections of threads have opposite thread directions, and the two sections of threads are respectively in threaded connection with the moving plates movably arranged inside the respective cavities, ensuring that the moving plates in threaded connection with the two sections of threads on the outer circle of the screw rod move towards or away from each other when the screw rod rotates.

[0013] Preferably, the notches are symmetrically arranged at two locations on one side of the frame body, and the edges of the two notches are both curved, and the two oblique plates movably connected inside the two notches are in an "eight" shape, and the oblique plates at this time will not affect the movement of the clamping plate.

[0014] Preferably, the outer ring of the fixing rod is movably sleeved with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the inner wall of the notch and the oblique plate, and the external force applied by the torsion spring and the oblique plate has a supporting effect on the clamping plate.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. The utility model drives the screw to rotate by turning the turntable, and the two movable plates connected with the screw can move toward or away from each other at this time, thereby driving the two clamping plates to move to synchronously clamp the two sides of the blade, so as to ensure that the clamping operation is carried out synchronously and the blade is always in the middle position of the placement groove on the inner wall of the frame body, which is convenient for subsequent transportation operations;

[0017] 2. At the same time, when the clamping plate moves, the force exerted by the torsion spring makes the oblique plate always press against the clamping plate, so that the clamping plate is supported by the oblique plate to clamp the blade, ensuring a better clamping effect.

[0026] The present utility model provides a Figures 1-4 clamping plate type blade transportation bracket as shown in the figure, including a frame body 3. Shock-absorbing legs 2 are fixedly connected to the four corners at the bottom of the frame body 3, and the shock-absorbing legs 2 are fixedly connected to the four corners of the base 1. A cavity 4 is opened inside the frame body 3, and a screw 5 is rotatably connected inside the cavity 4 through a bearing. The outer end of the screw 5 is fixedly connected with a turntable 6. A moving plate 7 is threadedly connected to the outer ring of the screw 5, and the moving plate 7 is integrally installed with the clamping plate 9 through a connecting short rod 8, ensuring that the movement of the moving plate 7 drives the movement of the clamping plate 9 to clamp the blade, facilitating subsequent transportation. It also includes:

[0027] A secondary support assembly 10. A notch 101 is opened inside the frame body 3, and a fixed rod 102 is fixedly connected to the inner wall of the notch 101. An oblique plate 103 is rotatably connected to the outer ring of the fixed rod 102 through a bearing. A bump 104 is fixedly connected to the end of the oblique plate 103, and the oblique plate 103 and the bump 104 move inside the chute 105 and the channel 106 provided inside the clamping plate 9. The chute 105 matches the channel 106, and the acting force applied by an external torsion spring supports the clamping plate 9.

[0028] A "U"-shaped placement groove is provided in the middle part of the frame body 3 for placing the lower end of the blade.

[0029] The cavity 4 is square, and there are two cavities 4. The two cavities 4 are symmetrically arranged left and right with reference to the vertical central axis of the frame body 3 as the axis of symmetry, and the two cavities 4 are not connected, facilitating the movement of the moving plate 7 and then driving the movement of the clamping plate 9 integrally installed with the moving plate 7 through the connecting short rod 8.

[0030] The screw 5 penetrates through the two cavities 4, and the screw 5 is rotatably connected to the through hole provided inside the frame body 3 through a bearing, ensuring the smooth rotation of the screw 5;

[0031] The outer ring of the screw 5 is provided with two sections of threads, the two sections of threads have opposite thread directions, and the two sections of threads are threadedly connected to the movable plates 7 movably connected inside each cavity 4 respectively. When the screw 5 rotates, it can be ensured that the movable plates 7 threadedly connected to the two sections of threads on the outer ring of the screw 5 can move towards or away from each other.

[0032] Two notches 101 are symmetrically arranged on one side of the frame body 3, and the edges of the two notches 101 are curved, and the two oblique plates 103 movably connected inside the two notches 101 are in an "eight" shape. At this time, the oblique plates 103 will not affect the movement of the clamping plate 9.

[0033] The outer ring of the fixing rod 102 is movably sleeved with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the inner wall of the notch 101 and the inclined plate 103 . The external force applied by the torsion spring and the inclined plate 103 play a supporting role for the clamping plate 9 .

[0034] Working principle: When using a clamping plate type blade transport bracket, firstly, the screw 5 fixedly connected to the rotating plate 6 is driven to rotate by toggling the rotating plate 6, and the two movable plates 7 threadedly connected with the two sections of the screw 5 outer ring with different screw directions can move toward or away from each other in the corresponding cavity 4, thereby driving the two clamping plates 9 connected with the two movable plates 7 by connecting the short rods 8 to move synchronously, so as to synchronously clamp the two sides of the blade placed in the placement groove inside the frame body 3, so as to ensure that the clamping operation is carried out synchronously, and ensure that the blade is always in the middle position of the placement groove on the inner wall of the frame body 3, which is convenient for subsequent transportation operations;

[0035] At the same time, when the clamp plate 9 moves, the force exerted by the torsion spring makes the inclined plate 103 connected to the torsion spring always press against the clamp plate 9, so that the clamp plate 9 is supported by the supporting force of the inclined plate 103 on both sides of the clamp plate 9, which makes it easier for the clamp plate 9 to clamp the blades and ensures a better clamping effect.
