Description

Technical Field

[0001] The utility model relates to the technical field of wind power hoisting, in particular to a wind power hoisting protection device. Background Art

[0002] Wind power generation is a technology that converts wind energy into electrical energy. As a clean and renewable energy source, in real life, humans usually install wind power devices to reduce dependence on fossil fuels, reduce greenhouse gas emissions, promote the diversification of energy structure, and enhance the security of energy supply. In the assembly process of wind power devices, corresponding lifting protection devices are usually used for installation.

[0003] For example, a wind turbine hoisting protection device in the prior art, patent number: CN218025046U, when in use, first use two cranes to move the wind turbine tower to the inner plate body, at this time the inner plate body is in a horizontal state, and one end of the end plate is close to one end of the tower, and then use a single crane for hoisting. During hoisting, as the tower tilts, the motor runs at the same time, and the main shaft is driven by the reducer to slow down the rotation. The main shaft drives the winding drum 1 and the winding drum 2 to rotate synchronously, so that one of the wire ropes 1 and 2 is tightened while the other is lengthened, so that the outer plate body rotates with the connecting shaft as the support shaft, and then the tower is reliably supported by the inner plate body and the end plate when it is tilted and hoisted.

[0004] However, in the prior art, the wind turbine tower is placed on the inner plate before installation. When the installation angle is adjusted, the outer surface of the wind turbine tower fits the inner plate and cannot be separated, which hinders the further installation and fixation process of the wind turbine tower. In addition, the rotating shaft is rotated by pulling the motor and the wire rope, and the environment of the wind turbine tower installation area needs to be further considered. In areas full of vegetation, the wire rope is easily entangled with the plants, affecting the construction. Utility Model Content

[0005] The utility model aims to solve the problem XXX in the prior art and proposes a wind power hoisting protection device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a wind power hoisting protection device, including a mounting block, an electric telescopic rod is arranged on the upper surface of the mounting block, a mounting bracket is rotatably connected to the mounting block, a first slide groove is provided on the upper surface of the mounting bracket, a load-bearing block is slidably connected in the first slide groove, a shock-absorbing groove is provided on one side of the first slide groove, a plurality of shock-absorbing springs are fixedly connected to the bottom of the shock-absorbing groove, a support plate is fixedly connected to the shock-absorbing spring, a threaded rod threadedly connected to the load-bearing block is arranged inside the mounting bracket, a motor is arranged at one end of the threaded rod, and the motor main shaft is fixedly connected to the end face of the threaded rod.

[0007] Preferably, the telescopic end of the electric telescopic rod is fixedly connected to a fixed block, and a T-shaped block is rotatably connected to the fixed block. A second slide groove is provided inside the mounting bracket and below the first slide groove. The T-shaped block is engaged in the second slide groove and slides along the inner wall of the second slide groove.

[0008] Preferably, the other end of the threaded rod passes through the mounting bracket, and an eccentric mounting baffle is fixedly connected to the outwardly extending portion, and the eccentric mounting baffle covers the interface of the mounting bracket.

[0009] Preferably, a rotation groove is provided on the outer thread surface of the threaded rod away from the motor, and a rotation sleeve is sleeved on the rotation groove.

[0010] Preferably, a balancing block is fixedly connected to the bottom of the mounting bracket and close to the motor, and the bottom of the balancing block is in contact with the mounting block.

[0011] Preferably, a storage bin is provided on the mounting block.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, by arranging the mounting support plate, the first slide groove, the motor, the threaded rod, the load-bearing block and the shock-absorbing groove, after the wind turbine sleeve is adjusted to a suitable unloading angle by the supporting action of the device, the rotation of the motor drives the rotation of the threaded rod, and under the limiting action of the first slide groove, the load-bearing block moves along the threaded rod away from the motor and passes through the gap between the wind turbine sleeve and the mounting support plate along the way, thus completing the separation of the wind turbine sleeve and the mounting support plate, avoiding the unloading and installation of the wind turbine sleeve affected by the excessive fit between the two.

[0014] 2. In the utility model, by setting a threaded rod, a rotating groove, a rotating sleeve and an eccentric mounting baffle, the load-bearing block moves along the threaded rod in the direction away from the motor and finally stops in the rotating groove. After that, the motor is allowed to rotate, and the load-bearing block is fixed in the rotating groove in combination with the rotating sleeve and no longer moves along the threaded rod. At this time, the eccentric baffle rotates with the threaded rod and deviates from the inlet of the mounting bracket, further assisting the wind turbine sleeve to detach from the mounting bracket, avoiding the load-bearing block from moving along the threaded rod and colliding with the inner wall of the first sliding groove, causing damage to the device while affecting the unloading of the wind turbine sleeve.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-4 As shown, a wind power hoisting protection device includes a mounting block 9, an electric telescopic rod 10 is arranged on the upper surface of the mounting block 9, a mounting bracket 1 is rotatably connected to the mounting block 9, a first slide groove 2 is opened on the upper surface of the mounting bracket 1, a load-bearing block 3 is slidably connected in the first slide groove 2, a shock-absorbing groove 5 is opened on one side of the first slide groove 2, a plurality of shock-absorbing springs 6 are fixedly connected to the bottom of the shock-absorbing groove 5, a support plate 7 is fixedly connected to the shock-absorbing spring 6, a threaded rod 4 threadedly connected to the load-bearing block 3 is arranged inside the mounting bracket 1, a motor 8 is arranged at one end of the threaded rod 4, and the main shaft of the motor 8 is fixedly connected to the end face of the threaded rod 4.

[0023] The specific working process of this scheme is as follows: the operator places the wind turbine sleeve on the mounting pallet 1 through a crane. After completion, the electric telescopic rod 10 on the mounting block 9 starts to operate and pushes the mounting pallet 1 to carry the wind turbine sleeve to complete the tilt angle adjustment. At this time, the motor 8 drives the threaded rod 4 to rotate, and the load-bearing block in the shock-absorbing groove 5 moves along the threaded rod 4 and separates the wind turbine sleeve and the mounting pallet 1 during the movement. After that, the traction and protection function of the crane are combined again to realize the unloading and further installation of the wind turbine sleeve.

[0024] like Figure 4As shown, the telescopic end of the electric telescopic rod 10 is fixedly connected to a fixed block 11, and a T-shaped block 12 is rotatably connected to the fixed block 11. A second slide groove 13 is provided inside the mounting bracket 1 and below the first slide groove 2. The T-shaped block 12 is engaged in the second slide groove 13 and slides along the inner wall of the second slide groove 13.

[0025] The purpose of this solution is that the telescopic end of the electric telescopic rod 10 extends and drives the T-shaped block 12 to move along the second slide groove 13, and the rotating end of the T-shaped block 12 rotates around the mounting block 9 while moving along the second slide groove 13, so as to complete the deflection angle adjustment and avoid the T-shaped block 12 and the electric telescopic rod 10 from getting stuck when pushing the mounting bracket 1 to rotate.

[0026] like Figure 2 As shown, the other end of the threaded rod 4 passes through the mounting bracket 1 , and an eccentric mounting baffle 14 is fixedly connected to the outwardly extending portion, and the eccentric mounting baffle 14 covers the interface of the mounting bracket 1 .

[0027] The purpose of this scheme is to prevent the wind turbine sleeve from detaching from the mounting bracket 1 by the eccentric mounting baffle 14, and to drive the eccentric mounting baffle 14 to rotate until it deviates from the inlet of the mounting bracket 1 by the threaded rod 4, and to realize the unloading of the wind turbine sleeve in combination with the traction and limiting effect of the crane.

[0028] like Figure 3 As shown, a rotation groove 15 is provided on the threaded surface of the threaded rod 4 and away from the motor 8 , and a rotation sleeve 16 is sleeved on the rotation groove 15 .

[0029] The purpose of this solution is that the motor 8 drives the threaded rod 4 to rotate, and the load-bearing block 3 moves along the threaded rod 4 until it stays in the rotating groove 15 and combines with the rotating sleeve 16, so that when the load-bearing block 3 moves to a specific position, it no longer moves along the threaded rod 4, thereby avoiding damage to the device.

[0030] like Figure 1 As shown, a balancing block 18 is fixedly connected to the bottom of the mounting bracket 1 and close to the motor 8, and the bottom of the balancing block 18 is in contact with the mounting block 9;

[0031] A storage bin 17 is provided on the mounting block 9 .

[0032] Further explanation of this solution: by providing the mounting block 9 to ensure the balance of the device and by carrying the balancing block 18 and the above-mentioned parts on the mounting block 9 when there is space, the force on the rotating shaft is reduced;

[0033] Furthermore, by providing the storage bin 17 , it is convenient for the staff to store necessary operating tools in the storage bin 17 , thereby further increasing the space utilization rate of the device.

[0034] Working principle: The wind turbine sleeve is hoisted onto the mounting bracket 1 by a crane, and the electric telescopic rod 10 pushes the mounting bracket 1 to rotate around the rotating axis, and drives the wind turbine sleeve to rotate until it reaches a suitable unloading position. At this time, the motor 8 drives the threaded rod 4 to rotate, and the load-bearing block 3 moves along the threaded rod 4 away from the motor 8, and separates the wind turbine sleeve and the mounting bracket 1 during the movement. After completion, the wind turbine sleeve is adjusted to a suitable angle for unloading and further installation is completed by combining the traction and auxiliary function of the crane again.

[0035] The wiring diagram of the motor 8 and the electric telescopic rod 10 in the present invention belongs to the common knowledge in the art, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the motor 8 and the electric telescopic rod 10 are not explained in detail.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
