Description

Technical Field

[0001] The utility model relates to the technical field of wind power construction, in particular to an offshore wind power bolt fastening fixture. Background Art

[0002] In the field of offshore wind power, the initial tightening process of bolts is a key step to ensure the structural safety of wind turbines. Although traditional offshore wind power bolt tightening fixtures provide a certain degree of assistance for such operations, they still expose multiple deficiencies in actual operation, especially in terms of adaptability to nuts of different spacings and specifications, and the ability to provide continuous clamping force during tightening.

[0003] First, the existing offshore wind power bolt tightening fixture design generally does not have the ability to flexibly adapt to nuts with different spacings. When installing offshore wind power components, the spacing of the bolts may vary depending on the design. The fixed or single-type design of traditional fixtures is difficult to meet the requirements of effectively clamping and tightening multiple nuts with different spacings at the same time, resulting in low work efficiency and increased installation time and cost; secondly, for nuts of different specifications, existing fastening tools often need to replace corresponding accessories or use multiple tools to adapt, which not only increases the burden on staff, but also increases the complexity and time cost of the operation. This lack of versatility and adaptability limits work efficiency and flexibility; finally, traditional fixtures often cannot provide continuous clamping force after clamping the nuts. In the special working environment of offshore wind power, if continuous clamping force is not provided, the nuts may loosen or even fall off due to vibration or other forces during operation, which not only affects the fastening quality, but also may bring safety risks.

[0034] Example 2

[0035] Reference Figure 2 to Figure 6 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0036] Specifically, the slider 201 is provided with a cylinder 201a, a first slide 201b, a second slide 201c, a channel 201d, a slide groove 201e, a side cylinder 201f, and a spring groove 201g. The cylinder 201a is arranged above the slider 201, the first slide 201b and the second slide 201c are arranged in the middle of the slider 201, the first slide 201b and the second slide 201c are arranged alternately, and the first slide 201b is arranged above the second slide 201c, the channel 201d is arranged at the intersection of the first slide 201b and the second slide 201c, and is connected to the cylinder 201a, the slide groove 201e is arranged on the inner wall of the cylinder 201a, the side cylinder 201f is arranged on the outer wall of the cylinder 201a, and is connected to the slide groove 201e, and the spring groove 201g is arranged on the inner wall of the cylinder 201a.

[0037] Specifically, the first clamping plate 202 and the second clamping plate 203 are both provided with a moving plate 204, a straight notch 205, and a first spring 206. The moving plate 204 is slidably matched with the first slideway 201b and the second slideway 201c respectively. The straight notch 205 is provided on the moving plate 204. The first spring 206 is provided between the moving plate 204 and the end surfaces of the first slideway 201b and the second slideway 201c.

[0038] It is worth mentioning that since the outer side of the nut is a regular hexagon, the angle between the movable plate 204 and the first clamp plate 202 in this scheme is 120°. In the initial state, the first spring 206 is at its original length, and the distance between the first clamp plate 202 and the second clamp plate 203 is the largest. At this time, the nut is placed between the first clamp plate 202 and the second clamp plate 203, and the adjacent sides of the nut are in contact with the side walls of the two movable plates 204. After the first clamp plate 202 and the second clamp plate 203 are subsequently contracted, the first clamp plate 202 and the second clamp plate 203 can just clamp the opposite sides of the nut.

[0039] Specifically, the first clamping plate 202 is also provided with a first rack 202a, and the first rack 202a is arranged on the side wall of the straight slot 205 on the first clamping plate 202; the second clamping plate 203 is also provided with a second rack 203a, and the second rack 203a is arranged on the side wall of the straight slot 205 on the second clamping plate 203, and the first rack 202a and the second rack 203a are arranged on different sides of the straight slot 205.

[0040] Specifically, the driving member 301 includes a gear cylinder 301a and a driving tube 301b. The upper end of the gear cylinder 301a is rotatably matched with the lower end of the channel 201d, and the driving tube 301b is slidably matched with the gear cylinder 301a.

[0041] The driving tube 301 b can drive the gear cylinder 301 a to rotate, and the gear cylinder 301 a can drive the first clamping plate 202 and the second clamping plate 203 to retract.

[0042] Specifically, the gear cylinder 301a is provided with a tooth block 301c and a spiral groove 301d. The tooth block 301c is arranged in the circumference of the gear cylinder 301a and meshes with the first rack 202a and the second rack 203a. The spiral groove 301d is arranged on the inner wall of the gear cylinder 301a.

[0043] The gear cylinder 301a is partially located in the channel 201d and rotates with the channel 201d. The portion with the tooth block 301c is located in the straight slot 205. When the gear cylinder 301a rotates, it will drive the first clamping plate 202 and the second clamping plate 203 to move in the opposite direction, thereby changing the distance between the first clamping plate 202 and the second clamping plate 203.

[0044] Specifically, the driving tube 301b is provided with a protrusion 301e, a straight groove 301f, and a through hole 301g. The protrusion 301e is slidably matched with the outer wall of the driving tube 301b and the spiral groove 301d. The straight groove 301f is provided on the inner wall of the driving tube 301b. The through hole 301g penetrates the side wall of the driving tube 301b.

[0045] It is worth noting that the drive tube 301b is longer than the gear tube 301a. Even if the drive tube 301b moves to the lower end of the gear tube 301a, the through hole 301g is still located above the gear tube 301a. In the initial state, due to the action of the first spring 206, the protrusion 301e is at the upper end of the spiral groove 301d.

[0046] Specifically, the locking member 302 includes a limit block 303, an extrusion block 304, and a telescopic block 305. The limit block 303 is slidably matched with the side tube 201f, the extrusion block 304 is slidably matched with the channel 201d, and the telescopic block 305 is disposed in the driving tube 301b and is slidably matched with the through hole 301g.

[0047] The limit block 303 only limits the upward movement of the extrusion block 304. The extrusion block 304 first drives the driving tube 301b to move, and then cooperates with the telescopic block 305 to limit the upward movement of the driving tube 301b and continuously applies pressure to the driving tube 301b, thereby providing continuous extrusion force on the nut. It is worth mentioning that the telescopic block 305 is in the shape of a capsule, and the spherical surfaces at both ends are made of rubber, which has a certain elasticity and a large friction.

[0048] Specifically, the limit block 303 is provided with a second spring 303a, a wedge block 303b, and a baffle 303c. The wedge block 303b is provided at the end of the limit block 303, the baffle 303c is slidably matched with the spring groove 201g, and the second spring 303a is provided between the baffle 303c and the end surface of the spring groove 201g;

[0049] In the initial state, the second spring 303a is at its original length, and the wedge block 303b extends out of the slide slot 201e. It is worth noting that the wedge block 303b is on the inclined end.

[0050] Specifically, the extrusion block 304 is provided with a ratchet bar 304a, a third spring 304b, an extrusion rod 304c, and a positioning block 304d. The ratchet bar 304a is arranged on the side wall of the extrusion block 304 and slides with the slide groove 201e. The extrusion rod 304c is arranged at the lower end of the extrusion block 304 and slides with the drive tube 301b. The third spring 304b is arranged between the extrusion block 304 and the end face of the drive tube 301b. The positioning block 304d is arranged on the side wall of the extrusion rod 304c and slides with the straight groove 301f. The lower end of the extrusion rod 304c is also provided with a slope 304e.

[0051] It is worth noting that the elastic coefficient of the third spring 304b is much larger than the elastic coefficient of the first spring 206. In the initial state, the squeezing block 304 is pressed downward, and the third spring 304b first squeezes the driving cylinder 301b downward (in this process, the third spring 304b is at its original length). The gear cylinder 301a is driven to rotate during the downward movement of the driving cylinder 301b, so that the first clamping plate 202 and the second clamping plate 203 are retracted inwardly. After the first clamping plate 202 and the second clamping plate 203 contact the outside of the nut, the first clamping plate 202 and the second clamping plate 203 no longer move, and the driving cylinder 301b cannot continue to move downward. At this time, the squeezing block 304 is continued to be pressed. In this process, the third spring 304b The compression, inclined surface 304e contacts with the telescopic block 305, squeezes it outward until one end thereof fits against the inner wall of the channel 201d. When the squeezing block 304 can no longer be pressed downward, the squeezing block 304 is released, and the wedge block 303b of the limit block 303 is engaged with the ratchet bar 304a, so that the squeezing block 304 cannot be lifted upward. At this time, the two ends of the telescopic block 305 are respectively tightly fitted with the channel 201d and the system 304e, and the driving cylinder 301b cannot move upward. Therefore, the first clamping plate 202 and the second clamping plate 203 cannot move, and the third spring 304b continues to squeeze the driving cylinder 301b, so that the first clamping plate 202 and the second clamping plate 203 continue to apply pressure to the nut to ensure that the nut does not fall.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
