Detailed Description

In the related art, the wind power tower may be a cylindrical steel structural member. The wind power tower can comprise a plurality of cylinder sections, and two adjacent cylinder sections are connected in a welding mode. In the process of preparing the cylindrical shell section, the steel plate can be rolled into the cylindrical shell section, and longitudinal seam welding is carried out on the cylindrical shell section on a welding table.

Wherein, the welding bench can include support piece and four gyro wheels, and four gyro wheels can set up in support piece's four corners to support the shell ring. In the process of longitudinal seam welding of the cylindrical shell section, the cylindrical shell section can be driven to rotate by driving the roller to rotate. When the inner longitudinal joint of the shell ring is welded, the shell ring can be driven by the roller, so that the inner longitudinal joint is positioned at the bottom of the shell ring, and when the outer longitudinal joint of the shell ring is welded, the shell ring can be driven by the roller, so that the outer longitudinal joint is positioned at the top of the shell ring, and the welding of workers is facilitated.

However, because the weight of the shell ring is great, and the welding table drives the shell ring to rotate through the gyro wheel, the width of gyro wheel is less for area of contact between gyro wheel and the shell ring is less, leads to the shell ring to exert the intensity of pressure at each gyro wheel great, thereby leads to the gyro wheel wearing and tearing seriously easily, has reduced the life of gyro wheel and welding table.

Based on at least one technical problem described above, an embodiment of the present application provides a rotating device, which may be used for rotating a member to be rotated, where the rotating device may include a first rotating member, a second rotating member, a driving member, and a supporting member, where the first rotating member and the second rotating member extend along a first direction and are disposed at intervals along a second direction, and the first direction and the second direction are different. The two ends of the first rotating piece and the second rotating piece along the first direction are both rotationally connected with the supporting piece, the driving piece is connected with the first rotating piece, and the driving piece can drive the first rotating piece to rotate through switch control. The peripheral outer walls of the first rotating piece and the second rotating piece are both used for being in rotary abutting connection with the peripheral outer wall of the piece to be rotated. So set up, because first rotating member and second rotating member all extend along first direction, be equivalent to, first rotating member and second rotating member's length direction is first direction, first rotating member and second rotating member have longer length in first direction, thereby make first rotating member and second rotating member all with wait to rotate the contact area of piece great, can reduce to wait to rotate the pressure of piece applys on first rotating member and second rotating member, thereby can alleviate the wearing and tearing between first rotating member, second rotating member and the shell ring, in order to prolong first rotating member, second rotating member and rotating device's life.

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The turning device 100 according to the embodiment of the present application will be described with reference to fig. 1 and 2.

The embodiment of the application provides a rotating device 100, and the rotating device 100 can be used for rotating a piece to be rotated. The member to be rotated may be cylindrical, columnar or spherical. The embodiment of the application is illustrated by taking a cylindrical shell section 200 (fig. 2) of a wind power tower with a cylindrical part to be rotated as an example. The shell ring 200 may be formed by crimping a metal plate, and the shell ring 200 may include a first end and a second end disposed along the crimping direction, and the first end and the second end may be welded to each other, that is, a longitudinal weld may be formed between the first end and the second end. The longitudinal welds can include an outer longitudinal seam and an inner longitudinal seam 210 (fig. 2), the inner longitudinal seam 210 can be located on an inner surface of the shell ring 200 and the outer longitudinal seam can be located on an outer surface of the shell ring 200. When the inner longitudinal joint 210 of the cylinder section 200 is welded, the cylinder section 200 can be driven to rotate by the rotating device 100 so that the inner longitudinal joint 210 is positioned at the bottom of the cylinder section 200, and when the outer longitudinal joint of the cylinder section 200 is welded, the cylinder section 200 can be driven to rotate by the rotating device 100 so that the outer longitudinal joint is positioned at the top of the cylinder section 200, thereby being convenient for a worker to weld. For example, when welding the outer longitudinal seam, the outer longitudinal seam is welded on the top of the cylinder section 200, which is a high-altitude operation, and the welding is relatively difficult, and the welding can be matched with the welding portal frame.

Referring to fig. 1 and 2, the rotating device 100 may include a first rotating member 111, a second rotating member 112, a driving member 120, and a supporting member 150, and the supporting member 150 may be used to mount the first rotating member 111 and the second rotating member 112. Both ends of the first and second rotating members 111 and 112 in the first direction X may be rotatably coupled to the supporting member 150. The driving member 120 may be connected to the first rotating member 111, and the driving member 120 may be used to rotate the first rotating member 111. The circumferential outer walls of the first and second rotation pieces 111, 112 can each be adapted to be in rotational abutment with the circumferential outer wall of the shell ring 200. The first rotating member 111 and the second rotating member 112 can both support the shell ring 200.

When the driving member 120 drives the first rotating member 111 to rotate, the first rotating member 111 drives the spindle 200 to rotate, and the spindle 200 drives the second rotating member 112 to rotate. The driving member 120 drives the cylinder section 200 to rotate through the first rotating member 111, so that the positions of the inner longitudinal slit 210 and the outer longitudinal slit of the cylinder section 200 can be adjusted. In addition, the cylinder section 200 drives the second rotating member 112 to rotate, so that sliding friction between the cylinder section 200 and the second rotating member 112 can be reduced, abrasion to the second rotating member 112 can be reduced, and the service life of the second rotating member 112 can be prolonged.

For example, the first and second rotating members 111 and 112 may each extend in the first direction X and be spaced apart in the second direction Y, and the first and second directions X and Y may be different. So set up, because first rotating member 111 and second rotating member 112 all extend along first direction X, be equivalent to, first rotating member 111 and second rotating member 112's length direction is first direction X, first rotating member 111 and second rotating member 112 have longer length in first direction X, thereby make first rotating member 111 and second rotating member 112 all with wait to rotate the area of contact of piece great, can reduce wait to rotate the pressure that the piece applyed on first rotating member 111 and second rotating member 112, thereby wear between first rotating member 111 that can alleviate, second rotating member 112 and shell ring 200, in order to lengthen the life of first rotating member 111, second rotating member 112 and rotating device 100, thereby avoid frequent maintenance to lead to production efficiency decline and cost of maintenance to rise.

For example, the first rotating member 111 and the second rotating member 112 may be carrier rollers, so that the structures of the first rotating member 111 and the second rotating member 112 are simpler, and the manufacturing cost of the first rotating member 111 and the second rotating member 112 may be reduced. Wherein the first rotating member 111 may form a driving idler and the second rotating member 112 may form a driven idler.

The first direction X and the second direction Y may be any two different directions parallel to the horizontal plane, for example, the first direction X and the second direction Y may be perpendicular to each other.

The rotating member (the first rotating member 111 and/or the second rotating member 112) provided by the embodiment of the present application will be described below.

In some examples, the rotor may include a rotor body that is stiffer and provides better support for the shell ring 200. For example, the material of the rotating body may be a metallic material. Both ends of the rotating body along the first direction X may be rotatably connected to the supporting member 150, the driving member 120 may be connected to the rotating body of the first rotating member 111, and the driving member 120 may be used to drive the rotating body of the first rotating member 111 to rotate. In other examples, the rotor may include a rotor body and a protector that may cover the outer wall of the rotor body in the circumferential direction, and the protector may protect the rotor body, reducing wear between the rotor body and the shell ring 200, and thereby extending the service life of the rotor body. The stiffness of the guard may be less than the stiffness of the rotating body so that the interaction forces between the shell ring 200 and the rotating body may be cushioned. Both ends of the rotating body along the first direction X may be rotatably connected to the supporting member 150, the driving member 120 may be connected to the rotating body of the first rotating member 111, and the driving member 120 may be used to drive the rotating body of the first rotating member 111 to rotate. The protector may be a noise reduction member that may be used to reduce noise between the rotating body and the shell ring 200. For example, the material of the protector may include rubber or other materials. The cost of the protecting piece is lower than that of the rotating body, and the protecting piece can be replaced without replacing the rotating body after being worn, so that the maintenance cost of the rotating piece can be reduced. The rotating member may be provided with only the rotating body without the protecting member, or may be provided with both the rotating body and the protecting member.

The protection member provided by the embodiment of the present application is described below.

In some examples, the protective member may include a protective layer that may cover the outer wall of the rotating body in the circumferential direction, and the protective layer may protect the rotating body. In other examples, the protection member may include a protection layer and a plurality of anti-slip protrusions, the protection layer may cover the circumferential outer wall of the rotating body, and the protection layer may protect the rotating body. The plurality of cleats may be disposed at intervals on a side of the protective layer facing away from the rotating body. The anti-slip protrusions can relieve sliding between the shell ring 200 and the rotating member, which is beneficial to stably driving the shell ring 200 to rotate, and can reduce abrasion between the shell ring 200 and the rotating member. Wherein the protection member may be provided with a protective layer without the stud, or may be provided with both the protective layer and the stud.

In the embodiment in which the protection member is provided with the stud, along a section perpendicular to the radial direction of the rotating body, the area of the stud is gradually reduced from the end close to the rotating body to the end far from the rotating body, so that the contact area between the stud and the shell ring 200 is large, which is advantageous for increasing the anti-slip effect. For example, the surface of the side of the protection protrusion facing away from the rotating body may be a curved surface, a conical surface, or the like.

The supporting member 150 provided in the embodiment of the present application is described below.

The support 150 may include a first support 151 and a second support 152, each of the first support 151 and the second support 152 may extend in the second direction Y, and the first support 151 and the second support 152 may be spaced apart in the first direction X. The first and second supporting members 151 and 152 may be supporting bars, so that the structure of the supporting member 150 may be simplified, and the manufacturing cost, the maintenance difficulty and the maintenance cost of the supporting member 150 may be reduced. Both ends of the first rotation member 111 may be connected to one ends of the first and second support members 151 and 152 in the second direction Y, respectively, and both ends of the second rotation member 112 may be connected to the other ends of the first and second support members 151 and 152 in the second direction Y, respectively, so that the first and second rotation members 111 and 112 may be connected to both ends of the support member 150 in the second direction Y, respectively. Both ends of the first support 151 may be connected to one ends of the first and second rotation members 111 and 112 in the first direction X, respectively, and both ends of the second support 152 may be connected to the other ends of the first and second rotation members 111 and 112 in the first direction X, respectively.

By connecting the first and second rotation members 111 and 112 between the first and second support members 151 and 152, stability of the overall structure of the support member 150 is facilitated, and simplification of the structure of the support member 150 is also facilitated. In the related art, the rollers are independently disposed at four corners of the supporting member, and the stability of the overall structure of the supporting member 150 cannot be enhanced, and the supporting member wants to have stronger stability, so that the structure of the supporting member 150 needs to be set more complicated, which results in higher cost of the welding table, and when failure occurs, the maintenance period is long, the production efficiency is low, and the maintenance cost is high. Therefore, the rotating device 100 provided by the embodiment of the application has the advantages of simplicity, practicability, lower cost, convenience in maintenance and the like.

For example, the support 150 may be provided with a first sliding groove and a second sliding groove, which may each extend in the second direction Y and are spaced apart in the first direction X. The first and second rotating members 111 and 112 may be formed at both ends thereof in the first direction X with first and second insertion parts, the first insertion part may be inserted in the first sliding groove, the first insertion part may be slid in the second direction Y in the first sliding groove, the second insertion part may be inserted in the second sliding groove, and the second insertion part may be slid in the second direction Y in the second sliding groove, so that the distance of the first and second rotating members 111 and 112 in the second direction Y may be adjusted, so that the rotating device 100 may be used for different sizes of the cylinder sections 200. For example, the turning device 100 may include a plurality of stoppers, which may be detachably connected to the support 150. Both sides of the first and second insertion parts in the second direction Y may be provided with a stopper, and after the distances of the first and second rotation members 111 and 112 in the second direction Y are adjusted, the positions of the first and second insertion parts may be defined by the stopper so as to fix the distances of the first and second rotation members 111 and 112 in the second direction Y, so as to avoid the distance from being changed during use. In embodiments in which the rotating member includes a rotating body, the first and second insertion portions may be located at both ends of the rotating body.

For example, the rotating device 100 may include a plurality of rolling bearings 130, and both ends of the first and second rotating members 111 and 112 may be rotatably coupled to the supporting member 150 through the rolling bearings 130. The rolling bearing 130 may change sliding friction between the rotating member (the first rotating member 111 and/or the second rotating member 112) and the supporting member 150 into rolling friction, thereby reducing friction loss between the rotating member and the supporting member 150. The rolling bearing 130 may include an inner ring, an outer ring, and rolling bodies and a cage between the inner ring and the outer ring, the inner ring may be coupled to the rotating member, the outer ring may be coupled to the supporting member 150 to play a supporting role, and the rolling bodies may be uniformly distributed between the inner ring and the outer ring through the cage.

In an embodiment in which the support 150 is provided with the first and second sliding grooves, both ends of the rotating member (the first and/or second rotating members 111 and 112) may be formed with the first and second insertion portions, which are inserted into the inner rings of the two rolling bearings 130, respectively, the rolling bearings 130 at the first insertion portion may be inserted into the first sliding groove and may slide along the first sliding groove, and the rolling bearings 130 at the second insertion portion may be inserted into the second sliding groove and may slide along the second sliding groove. Both ends of the rotating member may be slidably coupled to the supporting member 150 through two rolling bearings 130. Of course, in other examples, the first sliding groove and the second sliding groove may not be provided, and at least one of the rolling bearings 130 at both ends of the rotating member may be welded to the supporting member 150, so that the connection stability between the rolling bearings 130 and the supporting member 150 may be improved. Or at least one of the rolling bearings 130 at both ends of the rotating member may be screw-coupled with the support 150, thereby facilitating maintenance and replacement of the rolling bearings 130, for example, screw-coupling may be performed by at least two bolts. Or at least one of the rolling bearings 130 at both ends of the rotating member may be detachably connected to the supporting member 150 by a snap connection or the like, and the connection manner of the rolling bearings 130 and the supporting member 150 is not limited in the embodiment of the present application.

Illustratively, the turning device 100 may include a coupling 140, and the driving member 120 and the first turning member 111 may be coupled by the coupling 140. The coupling 140 may be used to connect an end of the first rotation member 111 and an end of the driving shaft of the driving member 120 together to transmit power. I.e., the driving shaft of the driving member 120 rotates and drives the first rotating member 111 to rotate through the coupling 140, so that the first rotating member 111 rotates with respect to the supporting member 150. For example, the driving member 120 may be a servo motor. In embodiments where the rotating member comprises a rotating body, the coupling 140 may be coupled to the rotating body.

Illustratively, the turning device 100 may be mounted on a mounting surface, which may be, for example, a floor. The turning device 100 may include a securing member that may be coupled to the support member 150, and the securing member may be used to secure the support member 150 to the ground. For example, the securing member may be an expansion bolt, thereby advantageously preventing vibrations from causing the shell ring 200 to drop.

Illustratively, the turning device 100 can include a height adjustment member that can be used to adjust the height of the support member 150 to adjust the heights of the first and second turning members 111, 112 so that a suitable distance between the shell ring 200 and the ground can be provided. For example, contact between the shell ring 200 and the ground can be avoided from wearing the shell ring 200. The height adjuster may be located at the bottom of the support 150 and connected to the support 150.

It should be noted that, the numerical values and the numerical ranges related to the embodiments of the present application are approximate values, and may have a certain range of errors under the influence of the manufacturing process, and those errors may be considered to be negligible by those skilled in the art.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the application.
