Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

In the related art, the wind power installation platform mainly includes a spud leg 170, a platform movably connected to the spud leg 170, and a hydraulic lifting system respectively connected to the spud leg 170 and the platform so as to enable the spud leg 170 and the platform to move relatively. The hydraulic lifting system mainly comprises: decide ring beam, the rotating ring roof beam, the oil cylinder subassembly and bolt subassembly, decide ring beam and the equal movably cover of rotating ring roof beam and establish at spud leg 170, the oil cylinder subassembly is located between deciding ring beam and the rotating ring roof beam, and the both ends of oil cylinder subassembly link to each other with deciding ring beam and rotating ring roof beam respectively, the bolt subassembly includes bolt, bolt hydro-cylinder and support, the support links to each other with the outer wall of deciding ring beam or rotating ring roof beam, the both ends of bolt hydro-cylinder link to each other with support and bolt respectively, so that the movably grafting of bolt is in spud leg hole 171 of spud leg 170. To avoid rotation of the spigot relative to the leg hole 171 during insertion, a key or keyway is typically provided between the spigot and the leg hole 171.

However, due to the rigid connection between the key and the key slot, the key and the key slot are severely worn by inserting and pulling the plug, and the rotation of the plug can also press the key slot to make the plug and the leg hole 171 continuously cling to each other, thereby causing the plug to be locked.

In order to solve the above technical problem, an embodiment of the present disclosure provides a bolt centering device, where fig. 1 is a schematic structural diagram of the bolt centering device, and referring to fig. 1, the bolt centering device includes: connecting components 1, elastic component 2 and righting frame 3. The righting frame 3 is used for being connected with a fixed ring beam or a movable ring beam of a hydraulic lifting system, the first part of the elastic component 2 is connected with the righting frame 3, the first part of the connecting component 1 is used for being connected with a bolt of the hydraulic lifting system, and the second part of the connecting component 1 is in contact with the second part of the elastic component 2, so that when the first part of the connecting component 1 moves under the driving of the bolt, the second part of the connecting component 1 compresses the elastic component 2.

Fig. 2 is a schematic view of the pin centralizer, and fig. 2 differs from fig. 1 in that a pin 151 is shown. The operation of the pin centralizer will be described with reference to fig. 2.

During insertion of the spigot 151 into the leg hole 171, if rotation occurs, the connector assembly 1 will rotate with the spigot 151 as the first part of the connector assembly 1 is connected to the spigot 151. At the same time, the second part of the connecting assembly 1 pushes the elastic assembly 2, so that the elastic assembly 2 is compressed by a small amplitude and accumulates elastic potential energy. During the process that the elastic member 2 is pushed by the coupling member 1, since the elastic member 2 applies an opposite elastic force to the coupling member 1, i.e., the latch 151, can be prevented from being rotated by a large amount. When the plug pin 151 is pulled out of the leg hole 171, the elastic potential energy of the elastic member 2 is released, so that the plug pin 151 can be driven to rotate in the reverse direction, thereby resetting the plug pin 151.

That is, the rotation of the plug 151 is not restricted rigidly throughout the insertion and extraction of the plug 151, but the rotation of the plug 151 is restricted flexibly by the elastic member 2. This prevents the plug 151 and the leg hole 171 from being locked.

From the foregoing, the connecting assembly 1 is used to transmit the acting force of the bolt, and the elastic assembly 2 can convert the acting force into its own elastic potential energy for storage, so as to achieve the effect of converting the rigid connection between the bolt and the leg hole 171 into the flexible connection in the prior art. Therefore, the connecting assembly 1 and the elastic assembly 2 are key components for achieving the above technical effects, and the connecting assembly 1 and the elastic assembly 2 are described below.

Fig. 3 is a schematic structural diagram of the connecting assembly 1, fig. 3 is a view in the direction a of fig. 2, and in combination with fig. 3, in this embodiment, the connecting assembly 1 includes a centering ring 11 and a centering arm 12, a first end of the centering arm 12 is connected to the centering ring 11, a second end of the centering arm 12 is in contact with the elastic assembly 2, and the centering ring 11 is configured to be connected to an end portion of the bolt 151 (see fig. 2).

In the above implementation, the centralizing ring 11 ensures stable connection between the connecting assembly 1 and the end of the plug 151, and the centralizing arm 12 is used for lengthening the moment arm of the connecting assembly 1, so that the connecting assembly 1 can more easily compress the elastic assembly 2.

Optionally, the righting ring 11 is an annular structural member, and when the righting ring 11 is connected to an end of the plug 151, the righting ring 11 is coaxially arranged with the plug 151.

Since the plug 151 rotates to drive the centering ring 11 to rotate synchronously, the coaxial arrangement can ensure that the rotation axis of the centering ring 11 is the same as that of the plug 151, so as to better transmit the acting force to the centering arm 12.

In other embodiments, the stabilizing ring 11 may also be multi-layered or have other shapes according to practical requirements, for example, the stabilizing ring 11 may be an ellipse or a rectangle, which is not limited by the present disclosure.

Optionally, the righting ring 11 is connected to one end of the plug 151 by a fixing bolt 5.

In other embodiments, other connection methods, such as welding, may be used between the centralizing ring 11 and the latch.

Optionally, a pin 6 is inserted between the centering ring 11 and the plug 151, and the pin 6 can bear a shearing force generated when a part of the plug rotates, so that abrasion of the centering ring 11 is reduced.

Illustratively, as shown in fig. 3, the fixing bolts 5 and the pins 6 in the centering ring 11 are arranged in a manner that four pins 6 are arranged on the centering ring 11, the pins 6 are symmetrically distributed on two sides of the axis of the centering arm 12 in a square shape, three fixing bolts 5 are arranged between two pins 6 on one side of the axis of the centering arm 12, two fixing bolts 5 are arranged between two pins 6 on the other side of the axis of the centering arm 12, and two fixing bolts 5 are arranged between two pins 6 far away from the centering arm 12.

Optionally, the centering arm 12 is a cylinder, and can always keep rolling contact with the elastic component 2 during operation, so that abrasion of the centering arm 12 is reduced, and jamming between the centering arm 12 and the elastic component 2 is avoided.

In other embodiments, the centering arm 12 may have other shapes, such as a rectangular parallelepiped, etc., according to practical requirements, which is not limited by the present disclosure.

Optionally, the centralizing ring 11 and the centralizing arm 12 are an integrated structural member to enhance the connection strength therebetween and prolong the service life.

In other embodiments, the centering ring 11 and the centering arm 12 may also be fixed by bolts according to actual requirements, so as to facilitate replacement when the centering ring 11 or the centering arm 12 is worn, which is not limited by the present disclosure.

Fig. 4 is a schematic structural diagram of the elastic member 2, and in conjunction with fig. 4, the elastic member 2 includes a clamping member 21 and an elastic member 22. The first side of the clamping member 21 is connected to the first end of the elastic member 22, the second side of the clamping member 21 is in contact with the righting arm 12, and the second end of the elastic member 22 is connected to the righting frame 3.

In the above implementation mode, the clamping member 21 is in contact with the centering arm 12, when the plug pin rotates, the centering ring 11 rotates, the centering arm 12 moves under the driving of the centering ring 11, the clamping member 21 in contact with the centering arm is compressed, and the elastic member 22 is compressed under the acting force of the clamping member 21, so that elastic potential energy is accumulated.

The clamping part 21 increases the stress area of the acting force of the righting arm 12 borne by the elastic part 22, so that the acting force is uniformly dispersed at each position of the elastic part 22, and the elastic part 22 compresses and accumulates elastic potential energy to provide power for resetting the plug 151.

Fig. 5 is a schematic structural view of the clamping member 21, and as shown in fig. 5, in the present embodiment, the clamping member 21 includes a clamping plate 211 and a guide post 212, a first end of the guide post 212 is connected to one side surface of the clamping plate 211, and a second end of the guide post 212 is movably connected to the righting frame 3.

In the above implementation, the guide post 212 fixes the direction of the elastic member 22 so that it is always located between the clamping plate 211 and the righting frame 3, and the rebound effect of the elastic member 22 is ensured.

Alternatively, the clamping plate 211 is a square copper plate, the straight edge is favorable for guiding the fixing elastic piece 22 during rebounding, and the copper alloy has good wear resistance and corrosion resistance, so that the service life of the part can be prolonged.

In other embodiments, the clamping plate 211 may have other shapes, such as rectangular and circular, and the clamping member 21 may be made of other materials, which is not limited by the present disclosure.

Optionally, the number of the guide posts 212 is four, and four guide posts 212 are arranged at intervals on the clamping plate 211 to play a role of fixing and guiding. Illustratively, four guide posts 212 are respectively near four corners of the clamping plate 211 to more stably support and guide the clamping plate 211.

In other embodiments, the guiding pillars 212 may have other shapes, such as rectangular parallelepiped, the guiding pillars 212 may have other numbers, such as six or eight, and the positions of the guiding pillars 212 may also be changed, such as positions near the middle points of the four sides. The present disclosure is not so limited.

Optionally, the guide posts 212 and the clamping plates 211 are an integral structure to enhance the connection strength therebetween and prolong the service life.

In other embodiments, the guiding column 212 and the clamping plate 211 can be connected in other manners, such as being fixed by bolts, according to actual requirements, so as to facilitate replacement when the guiding column 212 or the clamping plate 211 is worn, which is not limited by the present disclosure.

In this embodiment, a double nut 7 is connected to the second end of the guiding column 212, and the double nut 7 is located on a side of the righting frame 3 away from the elastic member 22, so that the righting frame 3 is clamped between the double nut 7 and the elastic member 22. By the design, the double nuts 7 can play a role in preventing looseness, and the guide column 212 is prevented from being separated from the righting frame 3.

Optionally, the clamping member 21 further comprises a wear plate 213, the wear plate 213 abutting a face of the clamping plate 211 facing the centering arm 12.

In the above implementation, the wear plate 213 is attached to the clamping plate 211, and the clamping plate 211 can be prevented from being worn quickly by the contact of the wear plate 213 with the centering arm 12.

Optionally, the wear-resisting plate 213 is a square copper plate, and the copper plate as a wear-resisting part can replace the clamping plate 211 to contact with the centering arm 12, so that the wear of the clamping plate 211 is reduced, and the maintenance and the replacement are convenient.

In other embodiments, depending on actual requirements, the wear-resistant member may not be provided, or the shape and material of the wear-resistant member may be changed, for example, a circular wear-resistant member is used to increase the utilization area, and a stainless steel wear-resistant member is used to reduce the use cost, which is not limited by the present disclosure.

In this embodiment, the elastic member 22 is a cylindrical compression spring, and is compressed by the clamping member 21 to accumulate elastic potential energy.

In other embodiments, the elastic member 22 may be other springs, such as a conical compression spring, according to practical requirements.

Alternatively, when the elastic member 22 is a cylindrical compression spring, the elastic member 22 can be movably sleeved on the guide post 212, and when the elastic member 22 is compressed and rebounded, the guide post 212 can limit the compression direction of the elastic member 22, and at the same time, the elastic member 22 is prevented from being pulled out.

Since the latch 151 moves in a direction parallel to the clamp plate 211 during insertion and extraction of the pile leg hole 171, in order to prevent the latch 151 from moving the centering arm 12 away from the clamp plate 211, in this embodiment, the stroke of the latch cylinder (the stroke of the latch 151) is S1, and the length of the clamp plate 211 in the latch moving direction is not less than S1. Meanwhile, the length of the clamping plate 211 in the moving direction of the bolt is designed to be longer, so that sufficient maintenance and replacement space can be conveniently reserved subsequently.

Alternatively, since the rotation direction of the plug pin depends on the uncertainty that the center of the leg hole 171 does not coincide with the center of the plug pin, and the center of the plug pin is eccentric with the center of the leg hole 171 in the actual process, the complete elastic member 2 includes two symmetrical parts, so that the plug pin can be restored to the state before insertion by the elastic member 2 in the opposite direction after being pulled out no matter which direction the plug pin is rotated.

From the foregoing, it can be seen that the centering arm 12 and the clamping plate 211 are in contact without any connection, and in order to ensure that the centering arm 12 does not move freely, when the elastic member 22 is a cylindrical compression spring, the single set of springs should have a preload S2 initially, and the initial preload of the spring is F1. To ensure that the spring force will return the latch to its initial state against the friction force, the initial spring preload F1 should be no less than the rotational friction of the latch.

Fig. 6 is an assembly schematic diagram of the elastic component 2 on the righting frame 3, as shown in fig. 6, the righting frame 3 includes a cover plate 33 and two side plates 31, the two side plates 31 are spaced from each other, one side of each of the two side plates 31 is connected to a fixed ring beam or a movable ring beam of the hydraulic lifting system, the cover plate 33 is connected to the other side of the two side plates 31, and the elastic component 2 is located between the two side plates 31 and is connected to the two side plates 31.

Alternatively, both the side plates 31 and the cover plate 33 may be rectangular, and the length direction of the cover plate 33 extends from one side plate 31 to the other side plate 31.

In this embodiment, the number of the elastic assemblies 2 is two, the elastic assemblies 2 correspond to the side plates 31 one by one, the clamping members 21 of the two elastic assemblies 2 are arranged oppositely, the centering arm 12 is clamped between the two clamping members 21, and the distance between the two clamping members 21 is L.

In the above implementation, the centering arm 12 is confined between the two elastic assemblies 2, ensuring that the centering arm 12 can be reset under the action of the elastic assemblies 2 no matter in which direction it is deflected.

Optionally, the side plate 31 and the cover plate 33 are welded and fixed.

In this embodiment, a side of the cover plate 33 facing away from the elastic assembly 2 has a support structure, as shown in fig. 2, the support structure includes two trapezoidal plates 331 and three rectangular plates 332, the two trapezoidal plates 331 extend along a length direction of the cover plate 33, the two trapezoidal plates 331 are parallel to each other, the three rectangular plates 332 are located between the two trapezoidal plates 331, the three rectangular plates 332 are perpendicular to the two trapezoidal plates 331, and the two trapezoidal plates 331 and the three rectangular plates 332 are connected to the cover plate 33.

In the above implementation, the strength of the cover plate 33 can be increased by the bracket structure.

In other embodiments, the support of the cover plate 33 may have other structures, such as vertical plates arranged in a "japanese" shape, according to practical requirements, which is not limited by the present disclosure.

The righting frame 3 further comprises a reinforcement rib 32, which reinforcement rib 32 is connected to the side of the side plate 31 facing away from the spring assembly 2.

In the above implementation, the side plate 31 is stably fixed on the outer side wall of the fixed ring beam or the movable ring beam of the hydraulic lifting system under the action of the reinforcing rib 32 and the cover plate 33, and the side plate 31 can be used for fixing the guide post 212, preventing the clamping member 21 from being removed, and simultaneously playing a role in fixing the direction of the spring.

Optionally, the ribs 32 are right trapezoid shaped.

In other embodiments, the ribs 32 may have other shapes, such as triangular, according to practical requirements, which is not limited by the present disclosure.

Fig. 7 is a schematic view of the structure of the guide assembly 4, the view of fig. 7 being indicated by the arrow b in fig. 6, and as shown in fig. 7, the pin straightening device further comprises the guide assembly 4, the guide assembly comprising a guide rail 41 and a slider 42, the guide rail 41 being connected to the side of the cover plate 33 facing the resilient assembly 2, the guide rail 41 extending in the direction of movement of the clamping member 21, the slider 42 being connected to the clamping member 21, the slider 42 being movably connected to the guide rail 41.

In the above implementation, when the bolt is inserted, the centering arm 12 pushes the clamping member 21, and under the action of the guide assembly 4, the clamping member 21 moves along the extending direction of the guide rail 41 and compresses the elastic member 22, and when the bolt is pulled out, the clamping member 21 is reset along the extending direction of the guide rail 41 due to the elastic force of the elastic member 22. That is, the guide rail 41 and the slider 42 cooperate to keep the elastic assembly 2 in a certain direction at all times during compression and rebound.

Alternatively, the guide rail 41 is formed of two parallel copper plates to form a dovetail groove. Correspondingly, the slide 42 is designed as a dovetail slide.

The bolt centering device provided by the embodiment of the present disclosure can be applied to a hydraulic lifting system, fig. 8 is a schematic structural diagram of the hydraulic lifting system provided by the embodiment of the present disclosure, referring to fig. 8, the hydraulic lifting system includes a pile fixing frame 100, a balancing component 110, a fixed ring beam 120, a lifting cylinder component 130, a movable ring beam 140, a bolt component 150, and a bolt centering device 160. The fixed ring beam 120 and the movable ring beam 140 are movably sleeved on the pile legs 170, the bottom of the pile fixing frame 100 is welded and fixed with the main deck surface of the platform, one end of the balance assembly 110 is fixedly connected with the pile fixing frame 100, the other end of the balance assembly 110 is hinged with the fixed ring beam 120 through a pin shaft, one end of the lifting oil cylinder assembly 130 is hinged with the fixed ring beam 120 through a pin shaft, and the other end of the lifting oil cylinder assembly 130 is hinged with the movable ring beam 140 through a pin shaft.

When the hydraulic lifting system climbs, firstly, the bolt oil cylinder on the fixed ring beam 120 inserts the bolt into the pile leg hole 171 to fix the fixed ring beam 120 on the pile leg 170, the bolt oil cylinder on the movable ring beam 140 pulls the bolt out of the pile leg hole 171, the movable ring beam 140 is separated from the pile leg 170, at this time, the lifting oil cylinder assembly 130 is shortened to lift the height of the movable ring beam 140 upwards, then the bolt oil cylinder on the movable ring beam 140 inserts the bolt into the pile leg hole 171 to fix the movable ring beam 140 on the pile leg 170, the bolt oil cylinder on the fixed ring beam 120 pulls the bolt out of the pile leg hole 171, the fixed ring beam 120 is separated from the pile leg 170, at this time, the lifting oil cylinder assembly 130 is lengthened to jack the fixed ring beam 120, and the hydraulic lifting system continuously climbs on the pile leg 170 in the process.

That is, in the whole process of climbing of the hydraulic lifting system, the lifting cylinder assembly 130 is complex to jack up the height of the whole device, and the bolt is used for fixing the whole device when the lifting cylinder assembly 130 extends to the longest or shortens to the shortest, and finally, the effect of enabling the whole device to climb continuously is achieved.
