Description

Technical Field

[0001] The present invention relates to the technical field of wind power construction, and more specifically, to a vertical lifting construction device for a wind power tower. Background Art

[0002] As a clean and renewable energy, wind energy is increasingly valued by countries around the world and has huge reserves. Wind power generation is one of today's new energy industries. At present, the usual way to transport maintenance materials in wind turbine towers is to install an electric crane on the top of the tower, connect the electric crane to the hook through a rope, hang the maintenance materials to be transported on the hook, and control the electric crane to tighten or lower the rope to move spare parts up and down in the tower, so as to achieve the purpose of transporting spare parts to the upper floors of the tower.

[0003] Among them, the patent with announcement number CN220334524U discloses a wind turbine tower maintenance material transportation device, which relates to the technical field of transportation devices and is applied to the inside of a wind turbine tower. A lifting assembly is arranged inside the wind turbine tower, and the lifting assembly includes a transportation box, which reciprocates linearly in a vertical direction, and a cross-shaped plate is fixedly connected to the bottom of the transportation box. A clamping assembly is arranged inside the cross-shaped plate, and the clamping assembly includes four evenly distributed extrusion plates, which move synchronously toward or away from each other;

[0004] When this structure is in use, the transport box is guided and lifted by the electric crane and the guide rod, so as to stably transport the maintenance materials without shaking. In addition, the extrusion plate moves synchronously and squeezes the guide rod to make the transport box land smoothly, thus protecting the internal materials and personal safety. However, this structure is relatively cumbersome when transporting materials, and it is not easy to install on the wind turbine tower, which causes a certain distance between the staff on the wind turbine tower and the device, making it difficult to store and access materials. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wind power tower vertical lifting construction device, aiming to solve the problems raised in the above-mentioned background technology.

[0006] The present invention provides the following technical solution: A wind power tower vertical lifting construction device comprises a base, on which a support assembly is arranged;

[0007] The support assembly includes a support frame arranged on the top of the base, the support frame is a rectangular frame structure, and a feeding frame is slidably connected to one side of the support frame;

[0008] Both ends of the feeding frame are fixedly provided with slide rails, and each of the slide rails extends to both sides of the support frame respectively, and the top ends of the two slide rails are rotatably connected with pulleys, and the pulleys are in contact with the support frame;

[0009] Two extension rods are installed on one side of the feeding rack through bolts, and one end of each of the extension rods is provided with a discharge rod.

[0010] It can be seen that in the above technical solution, the support frame is a rectangular frame structure, which is easy to be installed on the side of the wind turbine tower, so that the construction workers on the wind turbine tower can store and retrieve the materials transported by the device.

[0011] Optionally, in a possible implementation manner, the feed rack is rotatably connected to two axle pin seats by an axle pin, and each of the axle pin seats is provided with a limit plate, a conveyor belt is installed on one side of the limit plate by bolts, the limit plate is located on the outside of the conveyor belt, the middle part of the conveyor belt is transmission-connected with a rotating shaft, and both ends of each rotating shaft are rotatably connected with a bearing seat, the bearing seat is installed on the support frame by bolts, a reducer is provided at one end of the rotating shaft belonging to the top end of the support frame, a driving motor for driving the reducer to rotate is provided on one side of the reducer, the driving motor is installed on the top end of the support frame by bolts, the top end of the support frame is rotatably connected with a hook, the hook is hooked on the feed rack, and a plurality of buffer columns are provided on the top and bottom sides of the support frame;

[0012] It can be seen that in the above technical scheme, the driving motor drives the reducer to rotate, and when the reducer rotates, it drives the rotating shaft to rotate, and then pulls the conveyor belt to rotate. When the conveyor belt rotates, it will drive the limit plate to pull the feed rack to slide on one side of the support frame, and then realize the function of lifting and conveying the material on the discharge rod. At the same time, the pulley and the support frame rub against each other to guide and limit the displacement of the slide rail and the feed rack, thereby ensuring the stability of the feed rack during displacement, and then ensuring the stability of the material during transportation. When the feed rack rises to the top of the support frame, the hook is rotated so that one end of the hook can be hooked on the feed rack, which has the function of locking the feed rack to prevent it from falling off due to power failure.

[0013] Technical effects and advantages of the present invention:

[0014] By setting the support assembly, the support frame is a rectangular frame structure, which is easy to install on the side of the wind turbine tower, making it convenient for construction workers on the wind turbine tower to store and retrieve the materials transported by the device;

[0015] When the conveyor belt rotates, it will drive the limit plate to pull the feed rack to slide on one side of the support frame, thereby realizing the function of lifting and conveying the material on the discharge rod. At the same time, the pulley and the support frame rub against each other to guide and limit the displacement of the slide rail and the feed rack, thereby ensuring the stability of the feed rack during displacement, and then ensuring the stability of the material during transportation.

[0016] And when the feeding rack rises to the top of the supporting frame, the hook is rotated so that one end of the hook can be hooked on the feeding rack, thereby locking the feeding rack to prevent it from falling when the power is off. BRIEF DESCRIPTION OF THE DRAWINGS
