[0034] Example 1

[0035] Reference Figure 1 and Figure 2The angle-adjustable climbing platform comprises a support base plate 1, a hinged frame 2 and a moving assembly 3. The hinged frame 2 comprises two parallel hinged rods 21 and a plurality of support platforms 22 fixed between the two hinged rods 21. One side of the top surface of the support base plate 1 is provided with two rotating seats 23, which are arranged in one-to-one correspondence with the two hinged rods 21 and are rotationally connected with the two hinged rods 21.

[0036] Referring to Figure 1 and Figure 2 , the rotating seat 23 is provided with a locking member for locking the hinged rod 21, which comprises a locking bolt 4 and a locking nut 5. The locking bolt 4 penetrates the rotating seat 23 and the hinged rod 21 at the same time and is threadedly connected with the locking nut 5, and the locking nut 5 is abutted against one side of the hinged rod 21. The top side of the hinged rod 21 is vertically provided with a mounting handrail 24 along the length direction thereof.

[0037] Referring to Figure 1 and Figure 2 , the side of the hinged rod 21 close to the bottom and the bottom surface of the support base plate 1 are each provided with a plurality of anti-skid supports 25. The anti-skid supports 25 arranged on the hinged rod 21 are vertically arranged with the hinged rod 21, and the anti-skid supports 25 arranged on the support base plate 1 are vertically arranged with the support base plate 1. The moving assembly 3 is arranged in a plurality of groups on the hinged rod 21 and the support base plate 1. The moving assembly 3 comprises a moving trolley 31, an adjusting screw 32 and an adjusting seat 33. The adjusting seat 33 is connected to the side edge of the corresponding hinged rod 21 and support base plate 1, the adjusting screw 32 is vertically threadedly connected to the adjusting seat 33, and the moving trolley 31 is rotationally arranged at one end of the adjusting screw 32 close to the anti-skid support 25.

[0038] Referring to Figure 1 and Figure 2 , when the climbing platform is used, the hinged frame 2 is rotated to a suitable angle, the locking nut 5 is screwed, and the rotating action is locked with the hinged rod 21. When used, the anti-skid supports 25 arranged on the support base plate 1 are supported on the ground, and the anti-skid supports 25 arranged on the hinged rod 21 are supported on a slope or a higher building structure, thereby achieving the support of the hinged frame 2. The operator climbs through the support platform 22. Since the support base plate 1 is rotationally connected with the hinged frame 2, the relative angle between the two can be adjusted to adapt to different construction environments. When the device needs to be moved, the adjusting screw 32 is screwed, and the moving trolley 31 moves away from the support base plate 1 and the hinged frame 2. The hinged frame 2 is laid down, the moving trolley 31 arranged on the hinged frame 2 is in contact with the ground, which facilitates the movement of the device by the operator. The arrangement of the anti-skid supports 25 improves the contact friction between the hinged frame 2 and the support base plate 1 and the external structure, which helps to improve the structural stability of the climbing platform.

[0039] The implementation principle of the angle-adjustable climbing platform in the embodiment 2 of the present application is that when the climbing platform is used, the hinged frame 2 is turned to a suitable angle and locked. When used, the supporting bottom plate 1 is supported on the ground, and the hinged rod 21 is supported on a slope or a higher building structure, thereby achieving the support of the hinged frame 2. Since the supporting bottom plate 1 is rotationally connected with the hinged frame 2, the relative angle between the two can be adjusted to adapt to different construction environments.
