Abstract
Description
Technical Field
[0001] The present application relates to the technical field of wind power generation maintenance, and more specifically, to an insulating ladder for maintenance of wind power generation facilities. Background Art
[0002] With the continued consumption of non-renewable energy and the growing promotion of environmental sustainability, wind power generation, a green energy source, is also growing in addition to conventional coal-fired power generation. A wind turbine is an electrical device that converts wind energy into mechanical work, which in turn drives the rotor to ultimately output alternating current. Wind turbines typically include components such as a rotor, generator, yaw mechanism, tower, speed limiter, and energy storage device. Large wind turbines typically have their impellers positioned high to capture sufficient wind energy.
[0003] In the related art, workers need to regularly inspect and maintain the wind turbine to ensure that it can work properly. Generally, workers use an insulated maintenance ladder to climb to a high place to inspect and maintain the impeller.
[0004] However, traditional maintenance insulating ladders are prone to tipping over when supported on soft soil or hard cement ground, which undoubtedly increases the safety risks of workers when performing maintenance and repair operations. Utility Model Content
[0005] In view of this, an embodiment of the present application provides an insulating ladder for maintenance of wind power generation facilities to solve the problem in the prior art that the insulating ladder for maintenance is prone to tipping over when supported.
[0006] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:
[0007] An insulating ladder for maintenance of wind power generation facilities, comprising:
[0008] A first ladder frame and a second ladder frame, wherein the top ends of the first ladder frame and the second ladder frame are hingedly connected, and a fixing rope is provided between the first ladder frame and the second ladder frame; and L-shaped sliding grooves are provided on the lower sides of the first ladder frame and the second ladder frame;
[0009] a plurality of ladder beams, the ladder beams being fixedly mounted on the first ladder frame and the second ladder frame, the side walls of the ladder beams at the bottom ends of the first ladder frame and the second ladder frame being provided with protruding rods, the protruding rods passing through the L-shaped chute and extending outside the first ladder frame and the second ladder frame;
[0010] A rectangular cap head is provided at the end of the convex rod; wherein,
[0011] The ladder beams located at the bottom ends of the first ladder frame and the second ladder frame can move along the L-shaped sliding grooves so that the lower surfaces of the ladder beams are in contact with the ground.
[0012] In some possible implementations, a cavity is provided inside the ladder beam, and an opening communicating with the cavity is provided on a side surface of the ladder beam;
[0013] A support plate is slidably provided on the inner surface of the top plate of the ladder beam, and the support plate can slide out of the cavity to extend the upper surface area of the ladder beam.
[0014] In some possible implementations, the inner surface of the top plate of the ladder beam is hingedly connected to a connecting rod via a first hinge lug set, and the connecting rod is hingedly connected to the support plate via a second hinge lug set;
[0015] The connecting rod and the supporting plate are both provided with holes, and locking pins are inserted into the holes;
[0016] When the upper surface of the support plate is parallel to the upper surface of the ladder beam, the locking pin is inserted into the holes of the connecting rod and the support plate.
[0017] In some possible implementations, the sum of the length of the connecting rod and the thickness of the support plate is less than the depth of the cavity.
[0018] In some possible implementations, when the upper surface of the support plate is parallel to the upper surface of the ladder beam, the locking pin is inserted into the holes of the connecting rod and the support plate, so that the support plate contacts the top plate of the ladder beam.
[0019] In some possible implementations, the ladder beam is obliquely disposed between the first ladder frame and the second ladder frame, and a lower surface of the ladder beam is parallel to bottom end surfaces of the first ladder frame and the second ladder frame.
[0020] The insulating ladder for wind power generation facility maintenance provided by the embodiments of the present application has at least the following beneficial effects:
[0021] In the insulating ladder for wind power generation facility maintenance provided in the embodiment of the present application, the rectangular cap head can be grasped to control the movement of the ladder beam at the bottom end of the first ladder frame and the second ladder frame through the protruding rod. In actual use, the ladder beam at the bottom end is controlled to move along the L-shaped slide groove below the side of the first ladder frame and the second ladder frame until the ladder beam is moved to the bottom end of the first ladder frame and the second ladder frame, thereby increasing the contact area between the first ladder frame and the second ladder frame and the ground. With the above-mentioned structural design, the contact area between the insulating ladder and the ground can be increased by moving the ladder beam, thereby avoiding the problem of the insulating ladder tipping over when standing upright without the help of external structures, thereby effectively ensuring the safety of workers during the construction process.

DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0029] like Figure 1-Figure 3As shown, the insulating ladder for wind power generation facility maintenance provided by the embodiment of the present application includes a first ladder frame 100, a second ladder frame 200, and a plurality of ladder beams 500. The first ladder frame 100 and the second ladder frame 200 are rectangular frame structures. The top ends of the first ladder frame 100 and the second ladder frame 200 are hingedly connected. A fixing rope 300 is also provided between the first ladder frame 100 and the second ladder frame 200. The fixing rope 300 can fix the relative position of the first ladder frame 100 and the second ladder frame 200 and keep them in a herringbone state for convenience in subsequent use. In addition, L-shaped slide grooves 400 are provided at the lower positions of the sides of the first ladder frame 100 and the second ladder frame 200.
[0030] Each of the first and second ladder frames 100 and 200 is internally provided with multiple ladder beams 500, which are laterally overlapped within the first and second ladder frames 100 and 200. A protruding rod 600 is provided on the side of the ladder beam 500 at the bottom end of each of the first and second ladder frames 100 and 200. This protruding rod 600 extends through the L-shaped chute 400 and outward. A rectangular cap 700 is fixedly attached to the outer end of the protruding rod 600. By grasping the rectangular cap 700, the protruding rod 600 can be controlled to move the ladder beam 500 along the L-shaped chute 400.
[0031] In the insulating ladder for wind power generation facility maintenance provided in an embodiment of the present application, a rectangular cap head 700 can be grasped to control the movement of the ladder beam 500 located at the bottom end of the first ladder frame 100 and the second ladder frame 200 via a protruding rod 600. In actual use, the ladder beam 500 is controlled to move along the L-shaped chute 400 below the side of the first ladder frame 100 and the second ladder frame 200 until it is moved to the bottom end of the first ladder frame 100 and the second ladder frame 200, thereby increasing the contact area between the first ladder frame 100 and the second ladder frame 200 and the ground. This structural design increases the contact area between the insulating ladder and the ground by moving the ladder beam 500, thereby preventing the insulating ladder from tipping over when upright without the need for external structures, thereby effectively ensuring the safety of workers during construction.
[0032] In some embodiments, a cavity 510 is provided within the ladder beam 500, and an opening 520 communicating with the cavity 510 is provided on the side of the ladder beam 500. A support plate 800 is slidably provided on the inner surface of the top plate of the ladder beam 500. The support plate 800 can slide outward from the cavity 510 to increase the surface area of the top surface of the ladder beam 500. This allows workers to stand more stably on the ladder beam 500, thereby reducing the possibility of stepping on empty space.
[0033] Preferably, a first hinge lug set 540 is provided on the inner surface of the top plate of the ladder beam 500. The first end of the connecting rod 530 is connected to the first hinge lug set 540, and the second end of the connecting rod 530 is provided with a second hinge lug set 550. The second end of the connecting rod 530 is connected to the support plate 800 via the second hinge lug set 550. Both the connecting rod 530 and the support plate 800 are provided with holes 810, into which locking pins 900 can be inserted. The sum of the length of the connecting rod 530 and the thickness of the support plate 800 is less than the depth of the cavity 510. When the support plate 800 is rotated to a position parallel to the top plate of the ladder beam 500, the connecting rod 530 and the holes 810 of the support plate 800 overlap, allowing the locking pin 900 to be inserted into the holes 810, thereby securing the support plate 800.
[0034] In some embodiments, the ladder beam 500 is tilted above the first ladder frame 100 and the second ladder frame 200, and the inclination angle of the ladder beam 500 is parallel to the bottom end surfaces of the first ladder frame 100 and the second ladder frame 200, so as to ensure that the staff can stand safely on the ladder beam 500.
