Description
Technical Field

[0002] Wind turbines can be referred to as wind turbines. When the wind turbine is running, the loads transmitted from the tower to the foundation are very complex, generally including vertical loads, lateral loads, bending moments, etc. When starting and stopping, the wind turbine will swing back and forth in the wind direction. At this time, the load transmitted from the tower to the foundation will have a great impact on the foundation. The concrete around the pedestal will inevitably be subjected to uneven radial stress, resulting in stress concentration, which is very likely to crush and break the concrete, and then crack. In order to ensure the strength and service life of the wind turbine foundation, a large number of steel bars need to be applied, and the steel bars need to be adjusted in shape by bending and other means. In the prior art, traditional bending machines are mainly used to bend steel bars. The bending machine mainly includes a fixed disk and a rotating disk sleeved on a central axis. A push rod parallel to the central axis is connected to the rotating disk. The push rod passes through a circular arc groove opened on the fixed disk. When the push rod rotates, it cooperates with the central axis to bend the steel bar.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1 and 5 A wind turbine foundation steel bar bending device comprises a central shaft 6, a fixed disk 7 fixedly mounted on the central shaft 6 and a driven wheel 9 rotatably mounted on the central shaft 6, wherein the fixed disk 7 is provided with a guide groove 8 extending along the circumferential direction of the central shaft 6, the driven wheel 9 is fixedly connected with a connecting shaft 10 parallel to the central shaft 6, and the connecting shaft 10 passes through the guide groove 8, and a channel for the steel bar 12 to pass through is formed between the connecting shaft 10 and the central shaft 6.
[0024] The fixing plate 7 is detachably connected to a limiting member, and the limiting member can extend to the inside or side of the guide groove 8 to limit the connecting shaft 10 .
[0025] A plurality of guide wheels 11 are sleeved on the connecting shaft 10 , and the guide wheels 11 are threadedly connected to the connecting shaft 10 , and a guide gap for accommodating the steel bars 12 is formed between two adjacent guide wheels 11 .
[0026] When bending the steel bar 12, first determine the required width of the guide gap according to the size of the steel bar 12, and then rotate the guide wheel 11 to move the guide wheel 11 along the axial direction of the connecting shaft 10, thereby changing the distance between the two adjacent guide wheels 11, achieving the effect of changing the width of the guide gap, so that the steel bar 12 can smoothly enter the guide gap, and then connect the limiter to the appropriate position on the fixed plate 7 according to the required bending arc, and then drive the driven wheel 9 to rotate. During the rotation of the driven wheel 9, the connecting shaft 10 is driven to rotate in the guide groove 8, and then the connecting shaft 10 pushes the steel bar 12 located in the channel to bend and deform. During the process, the guide wheel 11 prevents the steel bar 12 from deflecting. When the connecting shaft 10 contacts the limiter, it cannot move further, thereby achieving the effect of using the limiter to limit the rotation amplitude of the driven wheel 9, and then achieving the effect of limiting the bending degree of the steel bar 12.
[0027] The utility model can be adjusted according to the size and bending degree of the steel bar 12 to be processed, and the limiting member is used as a hard limit to limit the bending degree of the steel bar. The processing accuracy is higher, different processing requirements can be met, the application range is wider, and the processing efficiency can be improved.
[0028] The device also includes a bending motor 3 for driving a driven wheel 9 to rotate, the bending motor 3 is drivingly connected to a driving wheel 4, and the driving wheel 4 and the driven wheel 9 are connected by a transmission belt 5. When bending the steel bar 12, the bending motor 3 drives the driving wheel 4 to rotate, and the driving wheel 4 drives the driven wheel 9 to rotate through the transmission belt 5, and then the driven wheel 9 drives the connecting shaft 10 to rotate, so as to bend the steel bar 12. Because the limit member acts as a hard limit to block the connecting shaft 10, the control accuracy requirement of the bending motor 3 is reduced, and the control process is also simpler.
[0029] Furthermore, the device also includes a supporting plate 1 , to which a supporting rod 2 for supporting the supporting plate 1 is fixedly connected, a central axis 6 is vertically fixed on the supporting plate 1 , and a bending motor 3 is arranged below the supporting plate 1 .
[0030] According to different structures of the limiting member, the utility model provides three embodiments.
[0031] Embodiment 1.
[0032] See also Figure 2 In this embodiment, the limit member includes a positioning column 14, which is fixedly connected to a blocking block 16 through a connecting block 15, and the axis of the positioning column 14 is parallel to the axis of the blocking block 16. A plurality of positioning holes 13 evenly distributed along the circumferential direction of the central axis 6 are formed on the end of the fixed plate 7 facing away from the driven wheel 9. When the positioning column 14 is inserted into the positioning hole 13, the blocking block 16 is inserted into the guide groove 8.
[0033] When bending the steel bar 12, first determine the position of the limit piece according to the needs, that is, determine which positioning hole 13 the positioning column 14 needs to be inserted into. Because all the positioning holes 13 are evenly distributed along the circumferential direction of the central axis 6, and the guide groove 8 also extends along the circumferential direction of the central axis 6, when the positioning column 14 is inserted into any positioning hole 13, it can be ensured that the blocking block 16 first extends into the guide groove 8, but the position in the guide groove 8 is different, so that the connecting shaft 10 can be blocked at different positions, thereby achieving the effect of changing the bending degree of the steel bar 12.
[0034] Embodiment 2.
[0035] See also Figure 3 In this embodiment, the limit member includes a limit block 18 and an insert block 19 that are coaxially fixedly connected. The guide groove 8 is connected to a plurality of sockets 17. The sockets 17 extend radially along the fixed disk 7, and all the sockets 17 are evenly distributed along the circumferential direction of the central axis 6. When the insert block 19 is inserted into the socket 17, the limit block 18 extends into the guide groove 8.
[0036] When bending the steel bar 12, first determine the position of the limit piece according to demand, that is, determine which socket 17 the insert block 19 is inserted into, and then insert the insert block 19 into the socket 17, so that the limit block 18 extends into the guide groove 8, thereby blocking the connecting shaft 10 during the rotation of the connecting shaft 10 with the driven wheel 9, thereby achieving the effect of changing the bending degree of the steel bar 12.
[0037] In order to facilitate the insertion of the plug block 19 into the socket 17, the plug block 19 is also fixedly connected to the gripping block 20 through a connecting rod. When the plug block 19 is inserted into the socket 17, the gripping block 20 is located outside the guide groove 8. The size of the gripping block 20 can be larger than that of the plug block 19, so that the staff can hold the gripping block 20 to operate the plug block 19.
[0038] Embodiment three.
[0039] See also Figure 4 In this embodiment, the limiting member includes a lever 23 detachably connected to the central shaft 6 , and the lever 23 extends radially along the fixed disk 7 , and extends to the outside of the guide groove 8 when the lever 23 is connected to the central shaft 6 .
[0040] When bending the steel bar 12, first connect the lever 23 to the central shaft 6 and make the lever 23 face the appropriate direction. Because the connecting shaft 10 needs to pass through the guide groove 8 to connect to the guide wheel 11, although the lever 23 is located outside the guide groove 8, it can still block the connecting shaft 10 during the rotation of the connecting shaft 10 with the driven wheel 9, thereby achieving the effect of changing the bending degree of the steel bar 12.
[0041] In order to facilitate the connection of the gear lever 23 to the central shaft 6, and to accurately control the orientation of the gear lever 23, while ensuring the stability of the orientation of the gear lever 23, the limiter also includes an inner regular polygon sleeve 21 fixedly sleeved on the central shaft 6, an outer regular polygon sleeve 22 movably sleeved on the inner regular polygon sleeve 21, and the gear lever 23 is fixedly connected to the outer regular polygon sleeve 22. The inner regular polygon sleeve 21 can limit the outer regular polygon sleeve 22 to prevent the outer regular polygon sleeve 22 from rotating, thereby achieving the effect of fixing the orientation of the gear lever 23. It should also be noted that because the driven wheel 9 needs to be sleeved on the central shaft 6, the inner regular polygon sleeve 21 and the outer regular polygon sleeve 22 can only be located on the side of the fixed disk 7 facing away from the driven wheel 9.
[0042] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
