Technical Field

[0001] This utility model relates to the field of wind turbine tower external ladder technology, and in particular to a wind turbine tower external ladder step positioning device. Background Technology

[0002] External ladders for wind turbine towers are used to facilitate workers' movement from the ground to the platform on the wind turbine tower. These ladders consist of steps and support plates, with the support plates located on both sides of the steps to provide support. In existing technology, for ease of transportation, the steps are typically installed on-site using welding to fix them individually to the support plates. While pre-set welding points are possible, installing each step individually is still cumbersome and inefficient.

[0003] To solve the above problems, a new type of positioning device for the steps of the external ladder of a wind turbine tower is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning device for the steps of the external ladder of a wind turbine tower. While ensuring convenient transportation of the steps, it enables the rapid fixing of the steps to the support plate, thereby improving the installation efficiency of the external ladder of the wind turbine tower.

[0005] To achieve the above objectives, this utility model provides a positioning device for the steps of an external ladder on a wind turbine tower, comprising two parallel support plates, with a plurality of detachably connected steps between the two support plates. Each step includes an integrally connected horizontal plate and a vertical plate. The side of the horizontal plate away from the vertical plate has symmetrically arranged magnetic metal posts. The vertical plate has insertion holes adapted to the structure of the magnetic metal posts, and magnetic snap fasteners are provided in the insertion holes. Both ends of the horizontal plate have protrusions, and the opposite sides of the two support plates have grooves, with the grooves corresponding to the protrusions one-to-one.

[0006] Preferably, the size of the groove is larger than the size of the protrusion.

[0007] Preferably, the top end of the support plate is connected to a connector, the connector including an upper connecting plate and a lower connecting plate, the upper connecting plate being fixedly connected to the upper surface of the wind turbine tower platform, and the lower connecting plate being fixedly connected to the lower surface of the wind turbine tower platform.

[0008] Preferably, the length of the lower connecting plate is greater than the length of the upper connecting plate.

[0009] Preferably, the top and bottom ends of the support plate are fixedly connected to the handrail.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. Example

[0019] like Figure 1-3As shown, a wind turbine tower external ladder step positioning device includes two parallel support plates 1, with several detachably connected steps 2 between the two support plates 1. Each step 2 includes an integrally connected horizontal plate 21 and a vertical plate 22. Symmetrically arranged magnetic metal posts 23 are provided on the side of the horizontal plate 21 away from the vertical plate 22. The vertical plate 22 has insertion holes 24 adapted to the structure of the magnetic metal posts 23, with magnetic snap-fits inside the holes 24. Inserting the magnetic metal post 23 from one step into the insertion hole 24 of the other step enables a detachable connection between the two steps. Both ends of the horizontal plate 21 have protrusions 25, and the opposite sides of the two support plates 1 have grooves 3, with each groove corresponding to a protrusion 25. Inserting the protrusion 25 into the groove 3 enables a detachable connection between the step and the support plate 1. The size of the groove 3 is larger than the size of the protrusion 25, effectively preventing the protrusion 25 from failing to insert into the groove 3 due to dimensional errors between the step and the support plate 1.

[0020] The top of the support plate 1 is connected to the connector 4, which secures the entire external ladder to the wind turbine tower platform. The connector 4 includes an upper connecting plate 41 and a lower connecting plate 42. The upper connecting plate 41 is fixedly connected to the upper surface of the wind turbine tower platform, and the lower connecting plate 42 is fixedly connected to the lower surface of the wind turbine tower platform. The upper connecting plate 41 and the lower connecting plate 42 can be connected to the wind turbine tower platform by welding. The length of the lower connecting plate 42 is greater than the length of the upper connecting plate 41, and the lower connecting plate 42 is used to increase the connection strength between the external ladder and the wind turbine tower platform.

[0021] The top and bottom of the support plate 1 are fixedly connected to the handrail 5, which facilitates climbing the ladder for workers. The bottom of the handrail 5 is connected to the adjusting support 6, which includes a support base 61 and a plug 62 located on the support base 61. The plug 62 has adjusting holes 63 evenly distributed along the vertical direction, and a fixing pin is installed in the adjusting hole 63. The bottom of the handrail 5 has a connecting hole that matches the fixing pin. By connecting the connecting hole with the adjusting hole 63 at different positions using the fixing pin, the external ladder can adapt to uneven ground.

[0022] In use, first use the connector 4 on one of the support plates 1 to fix the support plate 1 to the wind turbine tower platform. Then use the adjusting support 6 to make the bottom of the support plate 1 get stable support from the ground. Then use the magnetic metal plug 23 and the plug hole 24 to assemble all the steps 2. Then insert the protrusion 25 on the same side of the assembled steps 2 into the groove 3 of the installed support plate 1. Finally, install the other support plate 1 onto the wind turbine tower platform. During installation, connect the groove 3 on this support plate 1 to the protrusion 25 on the other side of the assembled steps 2. Finally, according to the connection strength requirements, the pedal and the support plate 1 can be welded and fixed.

[0023] Therefore, the wind turbine tower external ladder step positioning device with the above-mentioned structure can quickly fix the external ladder steps to the support plate while ensuring convenient transportation of the steps, thus improving the installation efficiency of the wind turbine tower external ladder.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
