Description

Technical Field

[0001] This utility model relates to the field of wind power towers, and in particular to a lifting device inside a wind power tower. Background Technology

[0002] A wind turbine tower is the supporting structure for a wind turbine generator set. Its main functions are: first, to support the nacelle, blades, and other components of the wind turbine, enabling it to obtain more stable and stronger wind energy at a suitable height. Generally, the higher the tower, the more abundant the wind energy resources that can be utilized, because wind speeds are faster at higher altitudes. Second, to ensure the stability of the entire wind turbine generator set, which needs to withstand enormous wind loads, gravity loads, and other complex external forces.

[0003] Wind turbine towers are designed to be very tall. To facilitate maintenance, ladders are usually installed inside the tower. When a wind turbine tower malfunctions, maintenance personnel can climb to the fault location for timely repairs. However, existing ladders are quite tall, making it difficult for maintenance personnel to climb, and there are safety hazards during the climbing process. This also makes it inconvenient for maintenance personnel to ascend and descend. Therefore, we propose an internal lifting device for wind turbine towers to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a lifting device inside a wind power tower to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lifting device for a wind power tower includes a support base. Two grooves are formed on the outer surface of the support base. Two drive motors are mounted on the bottom surface of the support base. Lifting blocks are slidably connected to the inner walls of both grooves. Threaded holes are formed on the upper surfaces of both lifting blocks. Screws are fixedly installed at the output ends of both drive motors. The outer surfaces of the two screws are threadedly connected to the inner walls of the two threaded holes. A support plate is fixedly connected to the front of both lifting blocks. A carrier plate is fixedly connected to the front of the support plate. A vertical plate is fixedly connected to the upper surface of the support plate. A guardrail is hinged to the outer surface of the vertical plate via a pin. A control panel is fixedly installed on the front of the vertical plate.

[0007] In a further embodiment, a positioning groove is provided on the upper surface of the carrier plate, and a positioning plate is fixedly connected to the bottom surface of the guardrail, with the bottom end of the positioning plate extending into the interior of the positioning groove.

[0008] In a further embodiment, two slide blocks are fixedly connected to the front of the support base, and sliding blocks are slidably connected to the inner walls of the two slide blocks. The front of the two sliding blocks is fixedly connected to the outer surfaces of the two lifting blocks, respectively.

[0009] In a further embodiment, two bearings are fixedly embedded in the inner walls of both grooves, and the inner rings of the two sets of bearings are respectively fixedly connected to the outer surfaces of the two screws.

[0010] In a further embodiment, the bottom surface of the guardrail is fixedly connected to a plurality of guard rods, the front surface of the upright plate is fixedly connected to two handles, and the outer surface of the support base is fixedly connected to an installation component.

[0011] In a further embodiment, two limiting plates are fixedly connected to the upper surface of the support base, and limit switches are fixedly installed on the bottom surface of both limiting plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model utilizes two sliding grooves on the support base to drive the motor, screw, and lifting block for installation. The operation of the drive motor, in conjunction with the screw and lifting block, allows the carrier plate and the maintenance personnel above to rise and fall flexibly. This enables automatic lifting and lowering of the maintenance personnel. Thus, this lifting device can be installed inside wind turbine towers, solving the problems of the current ladder-climbing system, which is laborious and poses safety hazards, and making the lifting and lowering of maintenance personnel more flexible.

A carrier plate 7 is fixedly connected to the front of the support plate 6. A vertical plate 8 is fixedly connected to the upper surface of the support plate 6. A guardrail 9 is hinged to the outer surface of the vertical plate 8 via a pin. A control panel 15 is fixedly installed on the front of the vertical plate 8. Through the operation of the drive motors 3 and their cooperation with the screws 5 and lifting blocks 4, the carrier plate 7 and the maintenance personnel above it can be flexibly lifted and lowered, improving the flexibility of use.

[0023] In a further embodiment, a positioning groove 11 is provided on the upper surface of the carrier plate 7, and a positioning plate 10 is fixedly connected to the bottom surface of the guardrail 9. The bottom end of the positioning plate 10 extends into the interior of the positioning groove 11. Two slide blocks 13 are fixedly connected to the front of the support base 1. Sliding blocks 12 are slidably connected to the inner walls of the two slide blocks 13. The front of the two sliding blocks 12 is fixedly connected to the outer surfaces of the two lifting blocks 4 respectively. Through the setting of the positioning groove 11 and the positioning plate 10, the guardrail 9 can limit the movement of maintenance personnel above the carrier plate 7, and play a role in protecting them during installation. Through the cooperation of the slide blocks 13 and the sliding blocks 12, the carrier plate 7 can be made more stable when it moves up and down.

[0024] In a further embodiment, two bearings 18 are fixedly embedded in the inner walls of the two slides 2. The inner rings of the two sets of bearings 18 are fixedly connected to the outer surfaces of the two screws 5 respectively. Multiple guard rods 20 are fixedly connected to the bottom surface of the guardrail 9. Two handles 14 are fixedly connected to the front surface of the upright plate 8.

The limit plates 16 and the limit switches 17 can be used to limit the movement of the lifting block 4 and the drive motor 3 upward.

[0025] The working principle of this utility model is as follows: First, the device is installed inside the wind power tower. Then, the device is connected to the power supply. Next, the maintenance personnel stand on the carrier plate 7 and hold the handle 14. Then, the two drive motors 3 are started to run in the forward direction, which can drive the screw 5 to rotate and cooperate inside the threaded hole 21. This allows the lifting block 4 to slide upward on the surface of the screw 5, and at the same time, it will drive the carrier plate 7 and the maintenance personnel above it to rise, thereby enabling the maintenance personnel to perform automatic lifting and lowering movements.
