The second end 120 of the support arm is connected to the first end 300a of the abutment and/or the second end 220 of the connecting arm is connected to the first end 300a of the abutment.

The second end 300b of the abutment member is a curved end for connection with the tower inner wall 21.

Referring to fig. 1 and 3, in the present embodiment, the supporting structure 1 includes at least one supporting frame 10, and each supporting frame 10 includes a supporting arm 100, a connecting arm 200 and an abutting member 300. One end of the support arm 100 is connected to one end of the connecting arm 200, and the support arm 100 and the connecting arm 200 are arranged at an acute angle, so that the support frame 10 and the tower inner wall 21 can form a triangular structure, and the stability is high. The abutting part 300 is used as a connecting part between the support arm 100 or the connecting arm 200 and the tower tube inner wall 21, and one end of the abutting part 300, which is used for being connected with the tower tube inner wall 21, is a curved end, so that the fitting degree with the tower tube inner wall 21 can be improved, and the stability of connection between the support arm 100 or the connecting arm 200 and the tower tube inner wall 21 is improved. The abutting pieces 300 are simple in structure, low in manufacturing cost and easy to replace, and the service life of the tower inner wall 21 can be effectively prolonged by using the abutting pieces 300 for connection.

The applicant considers that the abutment member 300 is not welded to the tower wall 21, and the tower wall 21 has a high fatigue resistance level, and therefore, the application provides a second connecting member 304, so that the abutment member 300 is connected to the tower wall 21 through the second connecting member 304.

Referring to fig. 1, 2 and 3, in the present embodiment, the first end 300a of the abutting member has a first adjusting hole 301, and the second end 300b of the abutting member has a second adjusting hole 302.

The first adjusting hole 301 is used for being matched with the first connecting piece 303 so that the first end 300a of the abutting piece is adjustably connected with the second end 120 of the supporting arm; and/or the first adjustment aperture 301 is adapted to cooperate with the first connector 303 to adjustably connect the first end 300a of the abutment with the second end 120 of the connecting arm.

The second adjustment aperture 302 is adapted to cooperate with the second connector 304 to adjustably couple the second end 300b of the abutment member to the tower inner wall 21.

In this embodiment, the first end 300a of the abutment member has a first adjusting hole 301 for cooperating with the first connecting member 303, so that the first end 300a of the abutment member is adjustably connected to the second end 120 of the support arm or the second end 120 of the connecting arm, so as to adjust the angle of the support frame 10 to an angle suitable for the operator, and to adapt to fit different types of tower inner walls 21.

Alternatively, the abutment member 300 may be one, but both ends thereof are adjustably connected to the second end 120 of the support arm and the second end 220 of the connecting arm, respectively.

Both of the above two possible embodiments use the first connecting member 303 to connect, so that the supporting arm 100 and the connecting arm 200 of the whole supporting frame 10 can be matched and adjusted to the angle relative to the inner wall 21 of the tower.

In this embodiment, the second adjustment aperture 302 is adapted to cooperate with the second connector 304 to adjustably couple the second end 300b of the abutment member to the tower inner wall 21. As mentioned above, when the abutment member 300 is welded to the tower inner wall 21, the tower inner wall 21 has a low fatigue resistance level, and the welded type fatigue resistance level is DC80 as certified by DNV (norwegian classification).

Alternatively, the second connector 304 may include, but is not limited to, a nail. The inventor of the application finds that the anti-fatigue grade of the tower drum inner wall 21 can be improved by adopting the shooting nail connection, and the anti-fatigue grade of the shooting nail fixing structure can reach DC90 and be higher than DC80 through DVC (Norwegian classification society), namely, the anti-fatigue grade of the tower drum inner wall 21 can be improved by the shooting nail fixing structure compared with welding, namely, the service life of the tower drum inner wall 21 is prolonged.

Optionally, the second adjustment aperture 302 is an elongated aperture extending along the curved surface of the second end 300b of the abutment.

In the present embodiment, the second connecting member 304 is connected to the tower inner wall 21 through the second adjusting hole 302, and the position of the second connecting member can be adjusted within a limited range of the second adjusting hole 302. The number of the second connecting members 304 may be one or more, and the second connecting members are fixed at the same time, so that the stability of the supporting structure 1 is improved.

In a possible embodiment, the support frame 10 further comprises: a backing plate 400. The backing plate 400 is disposed between the second end 300b of the abutment member and the tower inner wall 21.

Referring to fig. 2, in the present embodiment, the backing plate 400 may be configured in different shapes and structures, and when the curved end of the abutting member 300 cannot be well attached to the inner wall 21 of the tower, the backing plate 400 is configured to attach the backing plate 400 to the inner wall 21 of the tower, so that the support frame 10 is more stably connected to the inner wall 21 of the tower.

Optionally, the first regulation hole 301 includes a first regulation sub-hole 301a and a first fixed sub-hole 301 b; the first adjuster sub-hole 301a has a circular arc shape, and the first fixed sub-hole 301b is located at the center of the first adjuster sub-hole 301 a.

In this embodiment, both the first adjusting sub-hole 301a and the first fixing sub-hole 301b may be provided on the abutment member 300, and the first adjusting sub-hole 301a and the first fixing sub-hole 301b cooperate to enable the first connector 303 to connect the abutment member 300 with the support arm 100 and/or the connection arm 200, thereby adjusting the position of the connection arm 200 and the support arm 100 relative to the tower inner wall 21.

A first adjustment aperture 301 is provided on the first abutment member 310 in adjustable connection with the second end 120 of the support arm and/or the second end 220 of the connecting arm. In the manufacturing process, only the abutting piece 300 with relatively small volume and simple structure needs to be manufactured, so that the manufacturing cost is saved. The adjustment of the abutment member 300 by being fixed to the tower inner wall 21 is more sensitive than the adjustment of a movable member such as the support arm 100 or the connecting arm 200, and the operation is easier.

Optionally, the center of the first adjusting sub-hole 301a of the first abutting piece 310 coincides with the position of the first fixing sub-hole 301b of the second abutting piece 320.

It will be appreciated by those skilled in the art that the ladder is required to be climbed by a worker working within the tower 2, and therefore the support arm 100 of the ladder needs to be oriented horizontally to keep the worker horizontally stable. Whereas the tapered tower 2, which is rounded at its lower part and has a smaller cross-section in the upward direction, the support frame 10 arranged on the tapered tower wall 21 also needs to be adjusted horizontally towards the support arm 100, provided that the abutment 300 is adapted to abut against the tower wall 21. The first adjusting sub-holes 301a of the first abutting member 310 and the second abutting member 320, which are synchronously arranged, can adjust the angle of the support frame 10 relative to the tower inner wall 21 in the vertical direction, so as to meet the requirement of downward compensation of the support frame 10 of the ladder stand of the tapered tower 2.

In another possible embodiment, the second end 120 of the support arm has a third adjustment aperture (not shown). The third adjustment aperture is adapted to cooperate with the first connector 303 to adjustably connect the first end 300a of the abutment with the second end 120 of the support arm.

In this embodiment, a third adjusting hole is provided at the second end 120 of the support arm, and a sub-hole for fitting connection is also provided on the corresponding abutment 300, so as to connect the abutment 300 with the support arm 120 by fitting with the first connector 303. A fourth adjustment aperture is provided at the second end 220 of the connecting arm, and a sub-aperture is also provided on the corresponding abutment 300 for cooperating connection with the connecting arm 220 by cooperating with the first connector 303. By adopting the structure, the structure can adapt to various different application scenes, different positions of the third adjusting hole and the fourth adjusting hole can be adjusted according to the requirements of actual conditions, and the application range of the application is expanded.

In the present embodiment, the third regulation hole includes a third regulation sub hole (not shown in the drawings) and a third fixing sub hole (not shown in the drawings). The third adjuster aperture is located at the second end 120 of the support arm and the third stator aperture is located at the first end 300a of the abutment.
