Description

Technical Field

[0001] This utility model relates to the field of generator component transportation technology, and in particular to a shockproof transportation device for wind power generator components. Background Technology

[0002] The wind turbine generator set is the core component of a wind turbine generator set. It is responsible for converting wind energy into electrical energy and transmitting it to the power grid. Specific components include wind turbine, generator, gearbox, converter, etc.

[0003] During transportation, wind turbine generator components are protected from damage due to vibration through shock-absorbing structures. For example, Chinese Patent Publication No. "CN222391471 U" discloses a shock-absorbing generator set, relating to the field of generator set technology. It includes a soundproof enclosure and a generator set installed inside the enclosure, as well as an installation component. The installation component includes I-beams symmetrically arranged on the bottom wall of the soundproof enclosure, limiting grooves symmetrically opened on the inner walls of both sides of the enclosure, a base plate slidably installed inside the limiting grooves, and a threaded sleeve at the bottom of the base plate. During installation and disassembly of the generator set, workers can drive the threaded shaft to rotate via a handwheel, thereby extending the base plate outwards. This facilitates installation and disassembly of the generator set in the external space of the soundproof enclosure, further improving the efficiency of installation and disassembly and providing great convenience for workers. Furthermore, the adjustable protective cover provides good protection for the handwheel, preventing damage from collisions during use and ensuring smooth rotation of the threaded shaft.

[0004] In practice, multiple shock absorbers are used to dampen the components. However, the shock absorbers and the soundproof box cannot be disassembled for maintenance, or the cumbersome disassembly process affects the normal use of the transport device and the transport efficiency of the components. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, which allows for the inability to disassemble and maintain the shock absorber and the soundproof box, and to propose a shockproof transportation device for wind turbine generator components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a shockproof transportation device for wind turbine generator components, including a transport frame, a receiving groove and a support plate on the top of the transport frame, and a number of sets of support structures and shock-absorbing components are spaced apart between the support plate and the receiving groove. The support structure is used to reset the support plate to cooperate with the shock-absorbing components for buffering and shock absorption.

[0008] The shock-absorbing component includes an outer shell and a connecting part, which are fixed to the transport frame and the support plate respectively by a fixing structure.

[0009] Furthermore, the shock absorption assembly also includes a cylinder and a connecting rod. The outer shell is fixedly connected to the cylinder at the top, and the bottom of the cylinder has an air hole. The connecting rod is slidably connected to the cylinder through an end piston head.

[0010] Furthermore, the other end of the connecting rod is fixedly connected to a baffle, the outer shell is slidably connected to the connecting part, and both sides of the connecting part abut against the support plate and the baffle, respectively.

[0011] Furthermore, the fixing structure includes a positioning glass bead, the top of the support plate is provided with a stepped groove, the top of the connecting rod passes through the connecting part and the support plate, and is fitted with the positioning glass bead, and the telescopic column end of the positioning glass bead stops in the stepped groove.

[0012] Furthermore, it also includes a T-shaped rod, with grooves on both sides of the bottom of the outer casing. The T-shaped rod passes through the grooves and the transport frame. The T-shaped rod abuts against the outer casing through the protrusion at its top end, and an annular groove is provided at the bottom end of the T-shaped rod.

[0013] Furthermore, the bottom of the transport frame is slidably connected to a fixed plate via a guide member. Deformation grooves are provided on both sides of the end of the fixed plate. The deformation grooves are provided with protruding structures on both sides of the opening. The T-shaped rod slides against the protruding structures through the annular groove to be engaged in the deformation groove.

[0014] The present invention provides a shockproof transportation device for wind turbine generator components, which has the following advantages: The present invention provides a support structure and a shock-absorbing component between the transport frame and the support plate. When the support plate shakes, the generator component and the support plate move downward under the action of the connecting rod and the support rod. During the movement, the connecting rod is also squeezed downward. The connecting rod then achieves air damping between the piston head and the sleeve through the air hole. The air damping prevents the generator component and the support plate from bouncing back and forth, thereby achieving the purpose of shock absorption. In addition, after long-term use, the shock-absorbing component can be disassembled and maintained by unlocking the fixing structure. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A shockproof transportation device for wind turbine generator components includes a transport frame 1. A receiving groove 11 and a support plate 2 are provided on the top of the transport frame 1. The support plate 2 and the receiving groove 11 are spaced apart by a number of support structures 3 and shock-absorbing components 4. The support structures 3 are used to reset the support plate 2 to cooperate with the shock-absorbing components 4 for buffering and shock absorption.

[0024] The shock absorption component 4 includes an outer shell 41 and a connecting part 42. The outer shell 41 and the connecting part 42 are fixed to the transport frame 1 and the support plate 2 respectively by a fixing structure 5.

[0025] It should be added that a fixing frame is provided on the support plate 2. The fixing frame is used to support the generator assembly, and fixing straps can also be provided on both sides of the fixing frame to fix the generator assembly.

[0026] It should be added that the support structure 3 includes a support rod and a support spring 31. The support rod is fixedly connected to the bottom of the support plate 2, and the other end of the support rod is slidably connected to the transport frame 1 through the support spring 31. The two ends of the support spring 31 abut against the support plate 2 and the receiving groove 11, respectively.

[0027] Specifically, the support spring 31 is used to reset the support plate 2 and the connecting rod 44, and works with the piston head and the air hole 431 to achieve air damping, so as to avoid the generator assembly and support plate 2 from reciprocating and jumping due to the compression of the spring alone.

[0028] Furthermore, the shock absorption assembly 4 also includes a cylinder 43 and a connecting rod 44. The outer shell 41 is fixedly connected to the cylinder 43 at the top. The bottom of the cylinder 43 has an air hole 431. The connecting rod 44 is slidably connected inside the cylinder 43 through an end piston head.

[0029] Furthermore, the other end of the connecting rod 44 is fixedly connected to the baffle 441, the outer shell 41 is slidably connected to the connecting part 42, and the two sides of the connecting part 42 abut against the support plate 2 and the baffle 441 respectively.

[0030] In this embodiment, the specific principle of the shock absorption component 4 can be referred to the air damper in the prior art;

[0031] Specifically, when the generator assembly and the support plate 2 move downward, the support plate 2 abuts against and compresses the support spring 31 on the one hand, and abuts against the connecting part 42 on the other hand. The connecting part 42 abuts against the baffle 441 to drive the connecting rod 44 to move downward. The connecting rod 44 uses the piston head to compress the air inside the cylinder 43, so that the air is sucked in and discharged through the air hole 431, achieving the air damping effect.

[0032] More specifically, the fixing structure 5 includes a positioning glass bead 51, the top of the support plate 2 is provided with a stepped groove 21, the top of the connecting rod 44 passes through the connecting part 42 and the support plate 2, and is fitted with the positioning glass bead 51, and the telescopic column end of the positioning glass bead 51 is stopped in the stepped groove 21.

[0033] Specifically, the telescopic end of the positioning glass bead 51 is engaged in the stepped groove 21 to prevent the support plate 2 from separating from the connecting rod 44. After pressing the telescopic end of the positioning glass bead 51 to retract it and disengage it from the stepped groove 21, the support plate 2 and the connecting rod 44 can be separated.

[0034] In general, it also includes a T-shaped rod 52. The bottom sides of the outer shell 41 are provided with grooves 411. The T-shaped rod 52 passes through the grooves 411 and the transport frame 1. The T-shaped rod 52 abuts against the outer shell 41 through the protrusion at the top. An annular groove 53 is provided at the bottom end of the T-shaped rod 52.

[0035] Finally, the bottom of the transport frame 11 is slidably connected to a fixing plate 54 via a guide member 12. The fixing plate 54 has deformation grooves 541 on both sides of its end. The deformation grooves 541 have protruding structures 542 on both sides of their openings. The T-shaped rod 52 slides against the protruding structures 542 via the annular groove 53 to be engaged in the deformation grooves 541.

[0036] It is worth mentioning that the fixing plate 54 is preferably made of a material with deformation capability such as plastic or flexible metal. The fixing plate 54 slides under the action of the guide members 12 on both sides, and also engages the annular groove 53 of the T-shaped rod 52 through the deformation groove 541. The engagement can prevent the T-shaped rod 52 from detaching from the outer shell 41, thereby fixing the outer shell 41.

[0037] Among them, the fixing plate 54 has an L-shaped structure.

[0038] Working method: During operation, the generator assembly is fixed in the fixed frame on the top of the support plate 2. The transport frame 1 is moved by pushing the handle. During the movement, the generator assembly bumps and moves downward along with the support plate 2. The support plate 2, on the one hand, abuts and compresses the support spring 31, and on the other hand, abuts the connecting part 42. The connecting part 42 will drive the connecting rod 44 to move downward by abutting the baffle 441. The connecting rod 44 uses the piston head to compress the air inside the cylinder 43, so that the air is sucked in and discharged through the air hole 431 to achieve the air damping effect.

[0039] Then, the support plate 2 and the connecting rod 44 are reset under the action of the support spring 31;

[0040] When the shock absorption assembly 4 needs to be disassembled and maintained, the support plate 2 and the connecting rod 44 can be separated by pressing the telescopic column end of the positioning glass bead 51 through the stepped groove 21 to make it retract and disengage from the stepped groove 21.

[0041] When the fixing plate 54 is pulled out, the annular groove 53 of the T-shaped rod 52 slides against the protruding structures 542 on both sides and disengages from the deformation groove 541. Once the T-shaped rod 52 is disengaged, it can disengage from the groove 411 of the outer shell 41, and the outer shell 41 and the connecting part 42 can be disassembled.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
