Description

Technical Field

[0001] The utility model relates to a safety rope, in particular to a safety rope for wind turbine maintenance which is applied in the field of wind turbine maintenance. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine generally consists of a wind wheel, a generator (including a device), a direction regulator (tail wing), a tower, a speed limiting safety mechanism, and an energy storage device. The tower height of a modern large wind turbine is usually between 70 and 120 meters. When inspecting a wind turbine, workers need to climb to the generator and even need to inspect the condition of the blades at close range on the top of the cabin. They need to wear a safety rope for protection during the inspection process.

[0003] When working at heights, it is generally necessary to wear more than two safety ropes to ensure the safety of workers at heights. The safety ropes are generally connected to the connection points on the front chest or back of the straps. When workers observe the condition of the generator casing or blades at close range, the safety ropes located in front of the chest may obstruct the workers' line of sight. When workers perform repair welding, repainting and other operations on the generator, workers need to tilt their heads for a long time to work, which increases the physical burden of workers, makes it inconvenient for workers to work, and reduces operating efficiency. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a safety rope for wind turbine maintenance, comprising a safety rope body, the lower end of the safety rope body is fixedly connected with a hook, the outer ring of the safety rope body is respectively sleeved with a limit ring 1 and a limit ring 2, the limit ring 1 and the limit ring 2 are rotatably connected, the front end left part of the limit ring 1 is provided with a accommodating groove, the front end left part of the limit ring 2 is fixedly connected with a clamping block, the clamping block is clamped with the accommodating groove, the upper end of the limit ring 1 is fixedly connected with an adjusting box, the inner top wall of the adjusting box is fixedly connected with a spring, the upper end of the adjusting box is provided with a pull rod, the lower end of the pull rod sequentially penetrates the adjusting box, the spring, the limit ring 1 and the clamping block, and the lower end of the limit ring 1 is located in the accommodating groove, the outer ring of the pull rod is fixedly sleeved with a slide plate, the upper end of the slide plate is fixedly connected with the lower end of the spring, the front end of the limit ring 1 is fixedly connected with a clamping plate 1, the front end of the clamping plate 1 is provided with a clamping plate 2, the rear end of the clamping plate 2 is rotatably connected with a screw, and the rear end thread of the screw penetrates the clamping plate 1.

[0006] In the above-mentioned safety rope for wind turbine maintenance, when in use, the safety rope located in front of the chest can be limited to effectively prevent the safety rope from obstructing the workers' vision, thereby improving the workers' operating efficiency and facilitating the use of the workers.

[0007] As a further improvement of the present application, the rear end of the second clamping plate is fixedly connected to two limit rods, the rear end of the limit rods movably passes through the first clamping plate, and the screw rod is located between the two limit rods.

[0008] As a further improvement of the present application, the corresponding ends of splint one and splint two are fixedly connected with tooth blocks, the tooth block at the front end of splint one is triangular in shape, the tooth block at the rear end of splint two is isosceles trapezoidal in shape, and the front end of splint two is fixedly connected with a cushion.

[0009] As a further improvement of the present application, the limiting ring 1 and the limiting ring 2 can form a complete closed circle, and the diameter of the safety rope body is smaller than the diameter of the closed circle.

[0010] As another improvement of the present application, the safety rope body includes a fiber rope, an outer ring fixing sleeve of the fiber rope is provided with an elastic frame, the elastic frame includes a circular ring and vertical plates distributed in a circular array around the central axis of the circular ring, and an outer ring fixing sleeve of the elastic frame is provided with a protective shell.
