[0028] As Figures 1 to 5 shown in the figure, the ordinary ladder section 2 includes: two groups of main pipes 3; several groups of cross bars 4, evenly installed between the two groups of main pipes 3 for the user to climb; two groups of pin slots 5, respectively opened at both ends of the main pipe 3, and one group of pin slots 5 is configured to install the clamping part, and the other group is used to cooperate with the clamping part of other ordinary ladder sections 2 for combination.

[0029] As Figures 2 to 5 shown in the figure, the clamping part includes: a connecting piece 6, installed in the pin slot 5 at the top end of the ordinary ladder section 2, and is configured to be clamped with the pin slot 5 at the bottom end of another group of ordinary ladder sections 2; threaded grooves are opened at the connecting piece 6 and the pin slot 5, so as to fix the two groups of ordinary ladder sections 2 through bolts; the connecting piece 6 includes a bottom installation area and a top quick pin area, the installation area is adhered to the pin slot 5 of a group of ordinary ladder sections 2 and fixed by pins or bolts, and after the top quick pin area is clamped with the pin slot 5 of another group of ordinary ladder sections 2, it is also fixed by pins or bolts.

[0030] As Figures 3 to 5 shown in the figure, the hanging hook part includes: a locknut 7, located at the top of the maintenance ladder body 1; a hanging hook 8, installed at the top of the maintenance ladder body 1, and is configured to be fixed by the locknut 7.

[0031] Embodiment 2: As Figures 3 to 5 shown in the figure, the functional part includes: two groups of fixing blocks 9, located on the main pipe 3; a rotating block 10, installed between the two groups of fixing blocks 9, and the rotating block 10 is rotatably connected to the two groups of fixing blocks 9; a support plate 11, located on one side of the rotating block 10, and is configured to rotate left or right on one side of the main pipe 3 following the rotating block 10 when the ordinary ladder section 2 is placed vertically; a rotating shaft 12, installed between the support plate 11 and the rotating block 10 to enable the support plate 11 to rotate; a fence is installed on one side of the support plate 11 to prevent maintenance tools from falling and injuring personnel at the bottom of the maintenance ladder body 1.

[0032] The surface of the cross bar 4 is made of anti-slip material to increase the friction between the user and the cross bar 4; the anti-slip material is, for example, surface-bonded leather-grained cloth / paper, or the surface of the cross bar 4 is set to a matte surface.

[0033] The connecting member 6 is made of an insulating material to make the maintenance ladder body 1 insulating; the insulating material is preferably nylon material, and the connecting member 6 is fixed in the pin slot 5 by an adhesive method.

[0034] As Figure 1 shown in Figure 2 the figure, it further includes: a support foot pad 13, which is installed at the bottom end of the maintenance ladder body 1 and is used to increase the friction between the bottom end of the maintenance ladder body 1 and the contact surface.

[0035] In addition, rubber sleeves can be arranged as needed on the part between one end of the connecting member 6 installed on the main pipe 3 and two adjacent cross arm pipes. When climbing, holding by hand can prevent slipping, and in addition, it can reduce the collision damage of the ladder section.

[0036] For the technical solution provided by the present utility model, before using the maintenance ladder, first select an appropriate number of ordinary ladder sections 2 according to the height required for work. The two ends of the main pipe 3 of the ordinary ladder section 2 are respectively provided with pin slots 5. Install the connecting member 6 in the pin slot 5 at the top end of one ordinary ladder section 2, and then engage the pin slot 5 at the bottom end of another ordinary ladder section 2 with the connecting member 6. By analogy, several groups of ordinary ladder sections 2 are connected and combined into the maintenance ladder body 1 through the engaging part. Carry the assembled maintenance ladder to the working position, hook the fixed point at the working position through the hook 8 at the top end of the maintenance ladder body 1, and then tighten the locknut 7 to firmly fix the hook 8 at the working position. The user starts to climb the maintenance ladder. Multiple groups of cross arm pipes 4 are evenly installed between two groups of main pipes 3 for the user to step on. Since the surface of the cross arm pipe 4 is made of an anti-slip material, the friction between the user and the cross arm pipe 4 is increased, and the climbing safety is improved. When the user climbs to the top of the maintenance ladder body 1, the functional part starts to play a role. Since the rotating block 10 is rotatably connected to two groups of fixed blocks 9 on the main pipe 3, and the support plate 11 is connected to the rotating block 10 through the rotating shaft 12, when the ordinary ladder section 2 is vertically placed, the support plate 11 can follow the rotating block 10 and rotate left or right on one side of the main pipe 3, and at the same time rotate the rotating shaft 12 to adjust the angle of the support plate 11 for the convenience of the user; the user can place the maintenance tools on the support plate 11 for easy access; at the bottom end of the maintenance ladder body 1, the installed support foot pad 13 increases the friction between the bottom end of the maintenance ladder body 1 and the contact surface, making the whole maintenance ladder more stable and not easy to slide during use; and the connecting member 6 is made of an insulating material, making the whole maintenance ladder body 1 insulating and ensuring the safety of the user in a specific working environment; after the maintenance ladder body 1 is used up, after disassembling several groups of ordinary ladder sections 2, rotate the hook 8 to release the fixation between the hook 8 and the locknut 7. After the hook 8 rotates 90 degrees, it is convenient for storage. At the same time, rotate the support plate 11 towards the cross arm pipe 4 direction, and then rotate the rotating shaft 12 to make the support plate 11 in a vertical state for convenient storage.
