Description

Technical Field

[0001] The utility model relates to the technical field of electric cover plates, in particular to an anti-fall type electric cover plate for a hanging hole of a wind turbine generator set. Background Art

[0002] In wind turbines, due to the particularity of the installation site of the cabin equipment, during inspection and maintenance, personnel in the cabin will use large and heavy items or equipment to enter and exit the cabin, and these items or equipment cannot be transported to the cabin through the ladder channel in the tower. At this time, the cabin electric hoist will be used to lift these items or equipment into the cabin through the cabin lifting hole.

[0003] In the process of implementing this application, it was found that the technology has the following problems: the existing wind turbine cabin platform has two lifting holes, which are located on the cabin platform and the cabin cover respectively. The centers of the two lifting holes are on the same vertical line. When personnel lift objects, they need to open the cabin platform lifting hole cover and the cabin cover lifting hole cover. When personnel manually open the cabin cover, there is no special safety belt double hook hanging point. When opening the cabin cover, there is a great risk of falling. When personnel lift objects, in order to prevent people from falling, they can only hang the double hooks on the screen cabinet lifting ears or the cabin support rods. Due to the limited distance between the double hooks, the movement of personnel is greatly limited.

[0004] Therefore, an anti-fall type electric cover plate for the hanging hole of a wind turbine generator set is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that in order to prevent people from falling, double hooks can only be hung on the lifting ears of the screen cabinet or the support rods of the cabin. Due to the limited distance between the double hooks, the movement of people is greatly restricted. The utility model provides an anti-falling electric cover for the lifting holes of the wind turbine generator set.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] The camshaft is an electric cover for a hanging hole of an anti-falling wind turbine generator set, comprising a cabin platform bottom plate, a cabin cover bottom plate, a hinge and a positioning mechanism, wherein the upper surfaces of the cabin platform bottom plate and the cabin cover bottom plate are both provided with a feed port, and the upper surface of the cabin platform bottom plate is provided with two groups of grooves, and two groups of anti-falling cover plates 1 are slidably connected inside the two groups of grooves of the two groups of cabin platform bottom plates, and the positions of the two groups of anti-falling cover plates 1 are located at the upper end of the feed port of the cabin platform bottom plate, and the upper surface of the cabin cover bottom plate is hinged with an anti-falling cover plate 2 through the hinge, and the anti-falling cover plate 2 is clamped inside the feed port of the cabin cover bottom plate, and the upper surface of the cabin platform bottom plate is provided with a limiting mechanism for limiting the moving range of staff inside the wind turbine generator set, and the lower surface of the cabin platform bottom plate is provided with a driving mechanism, and the driving mechanism is installed on the upper surface of the anti-falling cover plate 2.

[0008] Furthermore, the limiting mechanism includes a positioning block and an electric telescopic rod, a slot is provided on the side of the anti-falling cover plate 2 away from the hinge, the electric telescopic rod is installed on the inner wall of the slot of the anti-falling cover plate 2 close to the hinge, a fixed block is installed on the output end of the electric telescopic rod, a slot is provided on the inner wall of the side of the feed port of the cabin cover bottom plate away from the hinge, the position of the slot inside the cabin cover bottom plate is located on the moving path of the fixed block, two groups of hook positioning holes are provided on the front of the positioning block, two groups of positioning holes are provided on the upper surface of the positioning block, and detection mechanisms are installed inside the two groups of positioning holes of the positioning block, the positions of the detection ends on the left and right sides of the detection mechanism are respectively set at the upper ends of the two groups of hook positioning holes, and the detection mechanism is electrically connected to the control end of the electric telescopic rod.

[0009] Furthermore, the driving mechanism includes a connecting block, which is installed on the lower surface of the cabin platform bottom plate, a motor is arranged on the front side of the connecting block, a driving rope is arranged on the outer surface of the output shaft of the motor, and one end of the driving rope away from the motor is installed on the upper surface of the anti-fall cover plate 2, and the detection mechanism is electrically connected to the control end of the motor.

[0010] Furthermore, the positioning mechanism includes a base, which is installed on the upper surface of a group of anti-fall cover plates close to one side of the positioning block. The upper surface of the base is provided with a support plate, and the upper surface of the support plate is provided with two groups of arc-shaped positioning grooves.

[0011] Furthermore, an arc-shaped fillet is provided at a corner of the base away from the positioning block, and the corner of the base away from the positioning block and a side of a right group of anti-falling cover plates away from the positioning block remain parallel.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The utility model adjusts and moves the two sets of safety rope hooks to insert the two sets of safety rope hooks into the two sets of hook positioning holes, triggering the detection mechanism to start the electric telescopic rod, so that the electric telescopic rod drives the fixed block to move out of the slot of the cabin cover bottom plate, so that the subsequent staff can rotate and open the anti-fall cover plate 2 only when they insert the two sets of safety rope hooks into the two sets of hook positioning holes, thereby avoiding as much as possible that the subsequent staff rotates to open the anti-fall cover plate 2 when they fail to connect the two sets of safety rope hooks to the inside of the limit mechanism, thereby preventing the subsequent staff from falling due to not wearing safety belts and hanging double hooks during the process of lifting objects inside the wind turbine generator set, thereby improving the safety of the device during use.

[0030] At the same time, the detection mechanism 403 detects that the two sets of safety rope hooks are moved out of the two sets of hook positioning holes 402, and the motor 802 is shut down. Then, under the action of gravity, the anti-fall cover plate 26 pulls the driving rope 803 to drive the output shaft of the motor 802 to rotate, thereby causing the anti-fall cover plate 26 to automatically reset, thereby avoiding as much as possible the anti-fall cover plate 26 being in an open use state when the two sets of safety rope hooks and the two sets of hook positioning holes 402 are disconnected by subsequent staff; the two sets of safety ropes are pressed to be clamped in the two sets of arc-shaped positioning grooves 703, so that the two sets of arc-shaped positioning grooves 703 limit the moving path of the safety rope dragged by the outer end of the staff's body, thereby avoiding as much as possible the subsequent staff being tripped by the safety rope they carry during walking.
