The clamping assembly 1 provided by the embodiment of the invention can be specially used for clamping the tower 2 of the wind generating set, and the tower hoisting equipment is specially used for hoisting the tower 2, and particularly, can be specially used for hoisting the one-section tower 2. Of course, the tower hoisting device can also hoist a sectional tower, and it can be understood that a constructor can also use the clamping assembly 1 and the tower hoisting device to clamp and hoist other components.

In the following, a clamping assembly 1 and a tower hoisting device using the clamping assembly 1 provided by the embodiment of the invention will be described by taking a tower 2 as an example with reference to fig. 1 to 3.

As shown in fig. 1, 2 and 3, an embodiment of a first aspect of the present invention provides a clamping assembly 1 for a tower lifting apparatus. The clamping assembly 1 comprises the hanging beam 10 and the clamping mechanism 20, the tower drum 2 is clamped through the clamping mechanism 20, the tower drum 2 is wrapped in a space surrounded by the hanging beam 10 and the clamping mechanism 20, the tower drum 2 can be prevented from falling off from the clamping assembly 1 easily, and therefore the tower drum lifting device using the clamping assembly 1 is beneficial to stabilizing the clamping tower drum 2, and safety risks are reduced.

The hanging beam 10 is a bearing structure of the whole clamping assembly 1, is positioned in the middle area of the clamping assembly 1 and is positioned at the top of the tower 2. By way of example, the lower surface of the hanging beam 10 is curved, which facilitates a better fit of the top of the tower 2 through the curved surface. Further, the curvature of the arc surface can be adapted to the curvature of the tower 2.

The clamping mechanism 20 comprises two clamping pieces 210, and the two clamping pieces 210 are symmetrically distributed on two sides of the hanging beam 10 in the width direction and are rotationally connected with the hanging beam 10. The two clamping pieces 210 are used for clamping the left and right sides of the tower 2, so that the clamping is stable.

The clamping mechanism 20 further comprises two driving members, which are connected to the two clamping members 210 in a one-to-one correspondence manner, and are used for driving the two clamping members 210 to rotate relative to the hanging beam 10. The clamping piece 210 is controlled to rotate through the driving piece, so that the control is convenient, and the clamping piece 210 can be used for fastening and clamping the tower 2 by means of applying pressure to the tower 2 through the driving piece.

Further, each driving member includes at least one driving element 230, and each clamping member 210 is driven to rotate by at least one driving element 230. The plurality of driving elements 230 can simultaneously drive one clamping piece 210 to rotate, so that on one hand, the clamping piece 210 can be stably driven to move, and on the other hand, even if one driving element 230 is damaged, the other driving elements 230 can apply thrust to the clamping piece 210 to ensure that the clamping tower 2 is stably clamped, and the clamping safety is improved.

Further, the driving element 230 is a telescopic driving structure such as a hydraulic cylinder or an electric push rod, and has a movable part that can be extended or retracted so that the second end and the first end thereof are far away from or near to each other. The clamping member 210 is rotatably connected to the hanging beam 10 through a first rotation shaft 220. The first end of the driving element 230 is rotatably connected to the hanging beam 10 through a first pin 231, and the second end of the driving element 230 is rotatably connected to the clamping member 210 through a second pin 232. When the movable part of the driving element 230 is extended, the second pin 232 is far away from the first pin 231, so that the clamping piece 210 is driven to rotate around the first rotating shaft 220 relative to the hanging beam 10, and the two clamping pieces 210 are opened or closed.

Further, as shown in fig. 1 and 2, a ridge beam 211 is provided on an outer surface of the holder 210, and a second end of the driving member 230 is rotatably connected to the ridge beam 211 through a second pin 232. The connection of the second pin 232 is facilitated without greatly affecting the structural strength of the clamping member 210.

To increase the versatility of the clamping assembly 1, in some embodiments, as shown in fig. 1 and 2, the clamping assembly 1 further comprises: the adjusting mechanism 30 is connected with the hanging beam 10 and the two clamping pieces 210 and is used for adjusting the distance between the hanging beam 10 and the two clamping pieces 210. The adjustable lifting beam is beneficial to adaptively adjusting the tower barrels 2 with different sizes, if the tower barrels 2 needing to be clamped are thicker, the distance between the lifting beam 10 and the two clamping pieces 210 is adjusted to be larger through the adjusting mechanism 30, and if the tower barrels 2 needing to be clamped are thinner, the distance between the lifting beam 10 and the two clamping pieces 210 is adjusted to be smaller through the adjusting mechanism 30, so that the lifting beam 10 and the two clamping pieces 210 on two sides can wrap the tower barrels 2 with different sizes.

In a particular embodiment, the adjustment mechanism 30 is capable of driving two clamps 210 toward or away from the hanger beam 10 simultaneously. The symmetry of the two clamping pieces 210 relative to the hanging beam 10 is improved, so that the two clamping pieces 210 are beneficial to stably clamping the tower 2 and are balanced in stress.

As an example, the adjusting mechanism 30 includes a motor (not shown in the drawing), a screw (not shown in the drawing) connected to both ends of the motor, and a movable block (not shown in the drawing) sleeved on the screw, and when the screw at both ends is driven by the motor to rotate, the movable block is movable along the screw by the rotation of the screw. The two movable blocks at the two ends of the motor are respectively connected with one clamping piece 210, so that the distance between the two clamping pieces 210 and the hanging beam 10 can be simultaneously pulled, or the two clamping pieces 210 can be simultaneously far away from the hanging beam 10.

At this time, the number of the adjusting mechanisms 30 may be two, and the two adjusting mechanisms may be distributed at both ends of the length direction of the hanging beam 10, so that each clamping member 210 is driven by two adjusting mechanisms 30 to move stably.

In addition, two guide holes 110 may be formed at both ends of the hanging beam 10 in the length direction, and two protruding first rotating shafts 220 may be formed at both ends of each clamping member 210, and each first rotating shaft 220 may be inserted into a corresponding guide hole 110. The first rotation shaft 220 moves along the guide hole 110 when the adjusting mechanism 30 drives the clamping member 210 to approach or separate from the hanging beam 10, which is advantageous for smooth movement of the clamping member 210. The two first rotating shafts 220 located at two ends of one clamping member 210 may be integrally formed and configured by a long shaft, or may be in a split structure, and are respectively connected with the clamping member 210 in a rotating manner.

Of course, in another example, two movable blocks may be respectively connected to the first rotating shafts 220 in the guide holes 110 of the two clamping members 210, and the two movable blocks are symmetrically distributed on two sides of the hanging beam 10, so that in the process that the movable blocks move along the screw rod, the first rotating shafts 220 are driven to move along the guide holes 110, and further the clamping members 210 are driven to approach or separate from the hanging beam 10.

In another particular embodiment, the adjustment mechanism 30 includes two sets of adjustment assemblies that respectively drive one of the clamps 210 toward and away from the hanger beam 10.

As an example, as shown in fig. 1 and 2, two guide holes 110 are provided at both ends of the hanging beam 10 in the length direction, two convex first rotating shafts 220 are provided at both ends of each clamping member 210, and each first rotating shaft 220 is inserted into a corresponding guide hole 110. The adjustment mechanism 30 is capable of adjusting the first rotation shaft 220 to move along the guide hole 110. Smooth movement of the clamp 210 is facilitated so that the first rotation shaft 220 can be moved away from or toward the hanger beam 10 along the guide hole 110, thereby allowing the clamp 210 to be rotated about the first rotation shaft 220 away from or toward the hanger beam 10. Each set of adjusting components may include an adjusting driving unit, where two first shafts 220 located at two ends of a clamping member 210 are integrally formed, that is, two first shafts 220 are formed by a long shaft, the length of the long shaft is greater than that of the clamping member 210, and the two first shafts 220 may extend through the clamping member 210 so that two ends of the first shafts extend out of the clamping member 210 to form a convex first shaft 220, and each adjusting driving unit is connected with one first shaft 220, that is, one first shaft 220 located at one end of the clamping member 210, so as to drive the whole long shaft to move along the guide hole 110, so that the distance between the edge of the clamping member 210 and the hanging beam 10 is relatively uniform. The two first shafts 220 protruding outward from the two ends of each clamping member 210 may be a split structure, and the two first shafts 220 are respectively connected with the clamping members 210 in a rotating manner, and at this time, each group of adjusting assemblies may include two adjusting driving units, which are respectively connected with the two first shafts 220 located at the two ends of the clamping members 210.

Further, each group of adjusting assemblies further comprises two transmission units respectively connected with the first rotating shafts 220 at two ends of the clamping member 210. Based on the condition that each group of adjusting components comprises an adjusting driving unit, one of the two transmission units is connected with the adjusting driving unit; based on the condition that each group of adjusting components comprises two adjusting driving units, the two transmission units are connected with the two adjusting driving units in a one-to-one correspondence. Whether each set of the adjustment assemblies includes several adjustment driving units, the two transmission units are connected to the first shafts 220 at both ends of the clamping member 210, which is advantageous in that the two first shafts 220 smoothly move so that the clamping member 210 smoothly moves.

Further, as shown in fig. 1 and 2, each transmission unit includes a gear 310 and a rack 320 engaged with each other, the gear 310 is sleeved on the first rotation shaft 220, and the rack 320 is laid on the inner side wall of the guide hole 110. Facilitating smooth movement of the first rotation shaft 220 along the guide hole 110.

The gear 310 is fixedly connected with the first shaft 220, the clamping member 210 is rotatably connected with the first shaft 220, and the adjusting driving unit is connected with one end of the first shaft 220. The first rotation shaft 220 may be moved along the guide hole 110 by the engagement of the gear 310 and the rack 320 and the holder 210 may be rotated about the first rotation shaft 220 when the first rotation shaft 220 is moved to an arbitrary position.

Further, each adjustment drive unit is a drive motor 330 or a manual rocker or hydraulic cylinder.

As shown in fig. 1 and 2, two first shafts 220 at both ends of one clamping member 210 are integrally formed and constructed of one long shaft, and the adjusting mechanism 30 includes two sets of adjusting members for driving one clamping member 210 toward or away from the hanger beam 10, respectively, each set of adjusting members including two adjusting driving units and two transmission units, each of the adjusting driving units being connected to one first shaft 220 at one end of the clamping member 210 through one transmission unit. Each adjusting driving unit is a driving motor 330, which is connected with one end of the first rotating shaft 220 away from the clamping piece 210, and drives the first rotating shaft 220 to rotate, so as to drive the gear 310 on the first rotating shaft 220 to move along the rack 320 in the guiding hole 110, and drive the clamping piece 210 to approach or separate from the hanging beam 10. The clamping member 210 may then be driven to rotate about the first rotation axis 220 by the driving member.

Of course, it is also possible to do without regard to whether the adjustment mechanism 30 is capable of driving two clamping members 210 closer to or farther from the hanging beam 10 at the same time or driving one clamping member 210 closer to or farther from the hanging beam 10, respectively, and instead to enable the adjustment mechanism 30 to adjust the movement of the first rotation shaft 220 along the guide hole 110. Smooth movement of the clamp 210 is facilitated so that the first rotation shaft 220 can be moved away from or toward the hanger beam 10 along the guide hole 110, thereby allowing the clamp 210 to be rotated about the first rotation shaft 220 away from or toward the hanger beam 10.

Further, as shown in fig. 1 and 2, the guide hole 110 is an arc-shaped hole, and extends to be bent downward from the top of the hanging beam 10. The lower surface of the hanging beam 10 is an arc surface, and the clamping member 210 is an inward curved arc plate shape. The curvature of the lower surface of the hanging beam 10, the curvature of the clamping member 210 and the curvature of the guide hole 110 are the same. Therefore, the adjusting mechanism 30 can adjust the clamping piece 210 to move along the bending radian of the lower surface of the hanging beam 10, so that the space surrounded by the adjusted hanging beam 10 and the two clamping pieces 210 is close to a columnar space, and the wrapping effect on the tower 2 is improved.

In the case that the adjusting mechanism 30 drives the two clamping members 210 to approach or separate from the hanging beam 10, if the position of the driving member is not moved, the driving range of the driving member is affected, and the rotation stroke of the clamping members 210 is affected. Thus, in some embodiments, as shown in fig. 1 and 2, the clamping assembly 1 further comprises: and an auxiliary adjusting mechanism 40, the auxiliary adjusting mechanism 40 connecting the hanging beam 10 and the two driving members for adjusting the two driving members to be close to or far from the widthwise edges of the adjacent hanging beam 10. Thus, when the driving mechanism drives the clamping piece 210 to be far away from the hanging beam 10, the auxiliary adjusting mechanism 40 can be used for adjusting the edge of the driving piece, which is close to the width direction of the adjacent hanging beam 10, and when the driving mechanism drives the clamping piece 210 to be close to the hanging beam 10, the auxiliary adjusting mechanism 40 can be used for adjusting the edge of the driving piece, which is far away from the width direction of the adjacent hanging beam 10, so that the movable stroke of the driving piece is ensured, and the rotating stroke of the clamping piece 210 is ensured.

Further, the auxiliary adjusting mechanism 40 includes a plurality of auxiliary adjusting components, the number of which is the same as that of the driving elements 230, and the auxiliary adjusting components are connected to the driving elements 230 in a one-to-one correspondence. Each auxiliary adjustment assembly drives one driving element 230 to move and in the case that the driving member includes a plurality of driving elements 230, the plurality of auxiliary adjustment assemblies drive a plurality of driving elements 230 connected to the same holder 210 to move.

As an example, as shown in fig. 1 and 2, each auxiliary adjustment assembly includes: a guide rail 410 provided at the top of the hanging beam 10 and extending in the width direction of the hanging beam 10; the sliding block 420 is matched with the guide rail 410 and can slide along the guide rail 410, a first end of the driving element 230 is rotationally connected with the sliding block 420, a second end of the driving element 230 is rotationally connected with the clamping piece 210, and the driving element 230 is of a telescopic driving structure; and a stopper for locking the relative positions of the slider 420 and the guide rail 410. The first end of the driving member 230 is moved along the guide rail 410 by the slider 420, and the movement is smoothed.

Wherein the driving element 230 is a telescopic driving structure having a movable part that can be extended or retracted so that the second end and the first end thereof are far away from or near each other. As the movable member of the drive element 230 extends, the second end of the drive element 230 moves away from the first end thereof, which urges the clamp 210 to rotate relative to the hanger beam 10. After the adjusting mechanism 30 drives the clamping member 210 away from the hanging beam 10, the sliding block 420 can be unlocked by the limiting member, and then the sliding block 420 is moved along the guide rail 410, so that the sliding block 420 approaches the edge of the adjacent hanging beam 10, and further the first end of the driving element 230 approaches the edge of the hanging beam 10 to move toward the clamping member 210, and then the relative position of the sliding block 420 and the guide rail 410 is locked by the limiting member. The second end of the driving element 230 can be far away from the first end of the moving driving element 230 by the maximum stroke when the driving element 210 is driven to rotate by the extension of the movable part of the driving element 230, thereby ensuring the driving range of the driving element 230 and the rotation stroke of the clamping element 210.

As shown in fig. 1 and 2, the driving elements 230 of the two driving pieces are symmetrically distributed in the width direction of the hanging beam 10. The plurality of auxiliary adjusting members are symmetrically distributed in the width direction of the hanging beam 10. The guide rails 410 of the two auxiliary adjusting assemblies symmetrically distributed in the width direction of the hanging beam 10 are integrally formed. The machining and installation of the guide rail 410 is facilitated as compared to the independent presence of the guide rail 410 of each auxiliary adjustment assembly.

As shown in fig. 1 and 2, the limiting member includes a limiting bolt 431 and a limiting nut 432, a limiting through hole 411 extending along the length direction of the limiting bolt 431 is provided on the guide rail 410, and the limiting bolt 431 passes through the sliding block 420 and the limiting through hole 411 to be connected with the limiting nut 432. The structure is simple, and the slide block 420 is convenient to fix.

In order to enable the two clamping members 210 to better clamp the tower 2, in some embodiments, as shown in fig. 1 and 2, each clamping member 210 is in an inward curved arc plate shape, that is, curved toward the direction of the tower 2, and the two clamping members 210 may enclose a cylindrical space, so as to conveniently accommodate the tower 2 and fully wrap the tower 2.

As an example, the inner surface of each clamping member 210 may be attached to the outer surface of the tower 2, and the tower 2 is directly clamped by using the clamping members 210, which has a simple structure and is convenient to process. Of course, the inner surface of the holder 210 may be bonded to the tower 2 by other members instead of being bonded to the tower 2.

In order to enhance the clamping effect of the clamping mechanism 20 in the case that the inner surface of the clamping members 210 is not in contact with the tower 2, in a specific embodiment, as shown in fig. 1 and 2, a plurality of protruding supporting members 240 are provided on the inner surface of each clamping member 210, and the supporting members 240 are used to contact with the tower 2. The tower 2 is supported by a plurality of supporting pieces 240 in a multi-point mode, and the clamping stability of the clamping mechanism 20 is improved.

Further, the support 240 can swing with respect to the inner surface of the holder 210. When the support 240 contacts the tower 2, the support 240 may swing to make full contact with and fit against the outer surface of the tower 2, thereby improving the clamping effect.

For the connection between the support 240 and the clamping member 210, in a specific embodiment, the bottom of the support 240 is provided with a second rotating shaft 250, and the inner surface of the clamping member 210 is provided with mounting lugs 214 distributed at two ends of the support 240, and the portion of the second rotating shaft 250 extending out of the support 240 is inserted into the two mounting lugs 214. The support 240 may swing around the second rotation shaft 250, and has a simple structure and convenient installation. Specifically, as shown in fig. 1 and 2, the second shaft 250 is a long shaft, and both ends thereof extend out of the support 240 to be connected to the mounting lugs 214. Of course, the number of the second rotating shafts 250 may be two, and the second rotating shafts may be respectively connected to opposite ends of the supporting member 240.

In another specific embodiment, the inner surface of the clamping member 210 is provided with an arc-shaped groove (not shown in the figure), the cross section of the arc-shaped groove has a circular structure with a cut-out top, and a rotating rod (not shown in the figure) is embedded in the arc-shaped groove, and the top of the rotating rod protrudes out of the arc-shaped groove and is connected with the supporting member 240. The convenient support 240 drives the rotating rod to rotate in the arc-shaped groove, thereby realizing swinging.

Further, the surface of the support 240 for fitting is an arc surface. For example, the arc surface is made to have the same curvature as the outer surface of the tower 2, so that the tower 2 can be sufficiently fitted.

Further, the supporting member 240 has a long plate shape, and increases the bonding area with the tower 2. Of course, the support 240 may be circular or square, etc.

Further, the support 240 is laterally disposed on the inner surface of the clamping member 210, i.e., extends in the axial direction of the clamped tower 2. Is convenient for being fully attached with the tower drum 2.

Of course, the third pin 511 and/or the fourth pin 512 may also be manually disengaged from the clamp 210.

Further, the pin driving member 520 may further drive the third pin 511 or the fourth pin 512 to rotate, thereby winding up the end of the protection belt 510, so that the length of the protection belt 510 can be adaptively adjusted, and the protection of the tower 2 is facilitated when the two clamping members 210 clamp the towers 2 with different sizes.
