Detailed Implementation

[0017] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0019] like Figures 1 to 9 The clamping device shown includes a support base 1, a pressure plate 2, a first clamping block 3, a second clamping block 4, and a quick-fastening assembly 5. The first clamping block 3 is detachably mounted on the support base 1, and the second clamping block 4 is detachably mounted on the pressure plate 2. The pressure plate 2 is located behind the support base 1, and the second clamping block 4 is located behind the first clamping block 3. A first clamping groove 31 is provided on the rear side of the first clamping block 3, and a second clamping groove 41 is provided on the rear side of the second clamping block 4. The first clamping groove 31 and the second clamping groove 41 constitute clamping holes 7 for clamping cables or pipes of wind turbine generator sets. The quick-fastening assembly 5 includes a screw 51 and a pull rod 53. The front end of the screw 51 passes through the pressure plate 2 and is fixedly connected to the bearing seat 1. The root of the pull rod 53 is hinged to the rear end of the screw 51 through a hinge structure. The root of the pull rod 53 is provided with an eccentric cam part 531. The pull rod 53 can rotate between a first position and a second position around the hinge axis of the hinge structure. When the pull rod 53 rotates from the first position to the second position, the eccentric cam presses the pressure plate 2 toward the bearing seat 1 to lock the cable or pipe located in the clamping hole 7. When the pull rod 53 rotates from the second position to the first position, the eccentric cam gradually releases the pressure on the pressure plate 2 to release the locking of the cable or pipe located in the clamping hole 7.

[0020] The above technical solution utilizes the quick-fastening component 5 to lock and unlock cables or pipes, offering ease of operation, reducing operator downtime and tool usage, and improving assembly / disassembly efficiency and operator safety. Both the first clamping block 3 and the second clamping block 4 are detachable and replaceable, allowing for quick adaptation to various wire and pipe diameters. Applying this clamping device to wind turbine generator sets provides a more reasonable and stable fixing method for newly installed cables and pipes. It also provides a more convenient installation method for disassembling and replacing cables and pipes during later maintenance of wind turbine generator sets. Currently, when wind turbine generator sets require the installation of later-removable equipment, bolt sets and welded nuts are generally used for fixing, but this is not very convenient; the above-mentioned wind turbine generator set can be used as a replacement for installations in frequently disassembled and opened locations.

[0021] This invention proposes a clamping device applicable to wind turbine generator sets, which can meet the layout and installation requirements of cables or pipes added after the wind turbine generator set; the clamping device can adapt to various wire diameters and pipe diameters, and has the characteristics of high disassembly and assembly efficiency and high operational safety.

[0022] In some embodiments, the clamping device includes two quick-fastening components 5, one of which is located to the left of the first clamping block 3 and the second clamping block 4, and the other is located to the right of the first clamping block 3 and the second clamping block 4. Using two quick-fastening components 5 enables a more secure clamping of cables or conduits.

[0023] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the pressure plate 2 is provided with two first screw 51 through holes that respectively cooperate with the screws 51 of the two quick fastening components 5. One of the first screw 51 through holes has a peripheral notch 25 for the screw 51 to enter and exit the first screw 51 through hole.

[0024] By adopting the above technical solution, a peripheral notch 25 is provided, which allows the pressure plate 2 to be easily detached from the screw 51 on one side, thereby reducing the difficulty of disassembling and assembling the clamping device.

[0025] In some embodiments, such as Figure 2 and Figure 4 As shown, one of the two first screw 51 through holes is a first strip hole 23 extending in the left-right direction, and the other of the two first screw 51 through holes is a second strip hole 24 extending in the up-down direction. A peripheral notch 25 is provided at the lower end of the second strip hole 24.

[0026] By adopting the above technical solution, the difficulty of disassembling and assembling the clamping device is further reduced, enabling rapid disassembly and assembly.

[0027] In some embodiments, such as Figure 1 , Figure 7 and Figure 8 As shown, the quick-fastening assembly 5 also includes a pressure block 52 fitted onto the screw 51. The pressure block 52 is located between the eccentric cam and the pressure plate 2. The front of the pressure block 52 is provided with a metal base 524 for supporting itself on the pressure plate 2, and the rear of the pressure block 52 is provided with a plastic part 525 for engaging with the eccentric cam. By providing the pressure block 52, the distance between the pull rod 53 and the pressure plate 2 can be increased, making it easier for the operator to operate the pull rod 53. The plastic part 525 can reduce the difficulty of operating the pull rod 53.

[0028] As a specific example, the screw 51 includes a screw body 511 and a hinge end 512, the hinge end 512 being provided with a first hinge hole 513. The pull rod 53 includes a pull rod body 533 and an eccentric cam portion 531, the eccentric cam portion 531 being provided with a second hinge hole 532. The pin 54 engages with the first hinge hole 513 and the second hinge hole 532 to hinge the screw 51 and the pull rod 53 together. The pressure block 52 is provided with a second screw through hole 521 that slides with the screw 51, and the bearing seat 1 is provided with a connecting screw hole 14 that is threadedly connected to the screw body 511.

[0029] As a specific example, such as Figure 8 and Figure 9 As shown, the eccentric cam portion 531 is provided with a first portion 534 and a second portion 535. The eccentric distance of the first portion 534 relative to the second hinge hole 532 is smaller than the eccentric distance of the second portion 535 relative to the second hinge hole 532. When the first portion 534 is engaged with the plastic portion 525, the pull rod 53 is in the first position. When the second portion 535 is engaged with the plastic portion 525, the pull rod 53 is in the second position.

[0030] In some embodiments, the rear end of the plastic part 525 is provided with a rear end face 523 and an arc surface 522 that is recessed rearward relative to the rear end face 523. The outer peripheral surface of the eccentric cam mates with the arc surface 522, and a limiting protrusion 536 is provided on the outer peripheral surface of the eccentric cam. When the pull rod 53 is in the second position, the limiting protrusion 536 is supported on the rear end face 523. By adopting the above technical solution, by providing the arc surface 522, the contact area with the eccentric cam part 531 can be increased, so that the clamping force is evenly distributed, avoiding unnecessary wear or crushing of the plastic part 525 caused by local stress concentration. By providing the limiting protrusion 536, a limit can be provided when the pull rod 53 rotates to the second position, preventing the pull rod 53 from rotating excessively.

[0031] In specific implementation, the metal base 524 of the pull rod 53, pin 54 and pressure block 52 can be made of hard alloy or stainless steel, the screw 51 can be made of 45# steel and then treated with anti-corrosion treatment such as blackening, and the plastic part 525 of the pressure block 52 can be injection molded from wear-resistant and low friction coefficient materials such as nylon and PTFE.

[0032] In practical implementation, an eccentric cam 531 is provided on the pull rod 53. Rotating the pull rod 53 pushes the pressure block 52 to move 4-5mm. When the pull rod 53 is pressed into place, the maximum pressing position is biased 10°-11° in the vertical direction. The limiting protrusion 536 of the pull rod 53 contacts the rear end face 523 on the pressure block 52 and maintains the pressing state. The holding force can be adjusted by the depth of the screw 51 screwed into the connecting screw hole 14.

[0033] In some embodiments, such as Figures 1 to 3 As shown, the support base 1 is provided with a first mounting groove 11, and a first protruding rib 13 is provided at the bottom of the first mounting groove 11. The first clamping block 3 is detachably embedded in the first mounting groove 11, and a first groove 32 is provided on the first clamping block 3 to cooperate with the first protruding rib 13. By adopting the above technical solution, the first mounting groove 11 combined with the first protruding rib 13 can achieve detachable positioning and installation of the first clamping block 3, which has the characteristics of being easy to implement.

[0034] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the pressure plate 2 is provided with a second mounting groove 21, and a second protruding rib 22 is provided at the bottom of the second mounting groove 21. The second clamping block 4 is detachably embedded in the second mounting groove 21, and a second groove 42 is provided on the second clamping block 4 to cooperate with the second protruding rib 22. By adopting the above technical solution, the second mounting groove 21 combined with the second protruding rib 22 can achieve detachable positioning and installation of the second clamping block 4, which has the characteristics of being easy to implement.

[0035] In some embodiments, the bottom of the first mounting groove 11 is provided with a plurality of mounting through holes 12. The rear end of the mounting through hole 12 is a countersunk hole structure. The fixing bolt 6 passes through the mounting through hole 12 and connects with the mounting surface. After the fixing bolt 6 is tightened, the bolt head is lower than the bottom surface of the second mounting groove 21 and does not interfere with the first clamping block 3.

[0036] In specific implementation, the support base 1 is provided with two connecting screw holes 14, which are located on the left and right sides of the first mounting groove 11, respectively.

[0037] In practical implementation, the bearing seat 1 and pressure plate 2 can be made of Q235B or Q345B structural steel; the fixing bolt 6 is selected as GB / T 70.1 socket head cap screw, and the matching standard is GB / T 97.2 flat washer.

[0038] In some embodiments, both the first clamping block 3 and the second clamping block 4 are plastic parts. They can be manufactured by injection molding, which is easy to implement.

[0039] Using the above technical solution, the first clamping block 3 and the second clamping block 4 adopt a modular design with consistent external dimensions and can be injection molded from materials such as nylon 1010. The plastic first clamping block 3 and the second clamping block 4 have self-adjusting capabilities, allowing them to hold cables or conduits within a certain range below their nominal diameter. The first clamping block 3 and the second clamping block 4 can be replaced according to the object being held, and by combining them with clamping blocks of various nominal diameters, a wider range of cable / conduit diameters can be supported.

[0040] In specific implementation, such as Figure 5 and Figure 6 As shown, a first mounting slot 11 can accommodate one or more first clamping blocks 3, and a second mounting slot 21 can accommodate one or more second clamping blocks 4. A first clamping block 3 can have one or more first clamping slots 31, and a second clamping block 4 can have one or more second clamping slots 41.
