Description

Technical Field

[0001] This utility model relates to the field of wind power installation technology, specifically a wind turbine blade hoisting support device with high stability. Background Technology

[0002] A highly stable wind turbine blade hoisting support device is used to support the suspended wind turbine blades during the hoisting process. It can provide a stable support point for the wind turbine blades and prevent structural deformation of the wind turbine blades during hoisting.

[0003] However, the existing wind turbine blade hoisting support devices, which have relatively high stability, still have shortcomings. Specifically, the existing hoisting support devices cannot limit the movement of the wind turbine blades, which makes the wind turbine blades prone to shaking and affects the hoisting efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a wind turbine blade hoisting support device with high stability 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 highly stable wind turbine blade hoisting support device includes a base, a support mechanism on the top of the base for supporting the hoisted wind turbine blade, wheels fixedly connected to the outer wall of the base, a control console fixedly connected to the top of the base, a battery fixedly connected to the outer wall of the base near the control console, a liquid storage tank fixedly connected to the center of the top of the base, a delivery pump fixedly connected to the bottom of the liquid storage tank inside the base, and a guide pipe fixedly connected to the outer wall of the delivery pump.

[0007] As a preferred embodiment of this utility model, the support mechanism includes a fixed sleeve fixedly connected to the top of the base. A piston plate is slidably connected inside the fixed sleeve. A telescopic rod is fixedly connected to the top of the piston plate and inside the fixed sleeve. A support frame is fixedly connected to the top of the telescopic rod and above the fixed sleeve. An electric slide rail is fixedly connected inside the support frame. A slide table is installed on the outer wall of the electric slide rail and inside the support frame. A limit plate is fixedly connected to the top of the slide table and above the support frame. Support pads are fixedly connected to the outer walls of both the support frame and the limit plate. A piezoelectric sensor is fixedly connected to the outer wall of the limit plate. A distance sensor is fixedly connected to the center of the inside of the support frame.

[0008] As a preferred embodiment of this utility model, both the base and the liquid storage tank are made of stainless steel, the liquid storage tank contains hydraulic oil, and the guide pipe has a C-shaped structure design.

[0009] As a preferred embodiment of this utility model, the top of the base is fixedly connected to multiple sets of concrete ballast blocks, and the control console is electrically connected to the battery.

[0010] Through the above technical solutions, concrete ballast blocks can lower the center of gravity of the base and improve its stability.

[0011] As a preferred embodiment of this utility model, the fixed sleeve, piston plate, telescopic rod and support frame are all made of stainless steel. The support frame has an H-shaped structure design. Two sets of the fixed sleeve, piston plate, telescopic rod and limiting plate are provided. The connection between the fixed sleeve and the guide pipe is a fixed connection.

[0012] As a preferred embodiment of this utility model, the support pad is made of silicone, and four sets of reinforcing plates are fixedly connected to the outer wall of the fixing sleeve. The limiting plate extends through and beyond the support frame, and the connection between the limiting plate and the support frame, and between the telescopic rod and the piston plate, are all sliding connections.

[0013] Through the above technical solution, the support pad of the silicone support is relatively soft and can deform when the wind turbine blades fall, thus avoiding direct collision between the falling wind turbine blades and the support frame.

[0014] As a preferred embodiment of this utility model, the outer wall of the piston plate is fixedly connected with multiple sets of sealing rings, the telescopic rod passes through and extends to the outside of the fixed sleeve, and multiple sets of piezoelectric sensors and distance sensors are provided. The electric slide rail, piezoelectric sensors and distance sensors are all electrically connected to the control console.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, a highly stable wind turbine blade hoisting support device is provided. The support mechanism within this device supports the hoisted wind turbine blade. The base is moved below the hoisted wind turbine blade. The control console starts the delivery pump, which sends hydraulic oil into the fixed sleeve through a guide pipe. The hydraulic oil entering the fixed sleeve pushes the piston plate upwards. The piston plate, through a telescopic rod, causes the support frame to rise. The support frame moves upwards to below the hoisted wind turbine blade. The control console then activates the electric slide rail, which, through a slide table, moves the limiting plate towards the wind turbine blade. When the limiting plate approaches and presses against the outer wall of the wind turbine blade, the piezoelectric sensor is squeezed by the blade. The squeezed piezoelectric sensor inputs a signal to the control console, which then shuts off the electric slide rail. The moving slide rail and electric slide rail no longer drive the limit plate to move. The limit plate blocks the fan blades, preventing them from sliding on the support frame. The support frame supports the fan blades, and the fan blades begin to be hoisted. The distance sensor detects the distance between the fan blades and the support frame. When the detected data exceeds the threshold, the control console starts the delivery pump. The delivery pump sends hydraulic oil into the fixed sleeve through the guide pipe. The hydraulic oil in the fixed sleeve pushes the piston plate upward. The piston plate drives the support frame to rise through the telescopic rod. The support frame rises together with the hoisted fan blades, always maintaining support for the fan blades. This solves the problem that existing hoisting support devices cannot limit the movement of the fan blades, causing them to sway and affecting hoisting efficiency. Attached Figure Description
