[0031] Embodiment 1:

[0032] See attached Figures 1 to 3 A non-slip ladder for power maintenance includes a main ladder frame 1 and a secondary ladder frame 2; the middle part of the main ladder frame 1 is hinged to the top of the secondary ladder frame 2; a cable steel rope positioning assembly 3 and a safety belt hanging member 4 are provided on the upper part of the main ladder frame 1; the cable steel rope positioning assembly 3 is used to fix the relative position between the main ladder frame 1 and the ground by using a cable steel rope 32 after the secondary ladder frame 2 is unfolded; the safety belt hanging member 4 is arranged on the upper part of the main ladder frame 1 and is used for detachably cooperating with the safety belt worn by the staff. From the above structure, it can be seen that both the main ladder frame 1 and the secondary ladder frame 2 are made of insulating materials to ensure the safety of use. The middle part of the main ladder frame 1 is hinged to the top of the secondary ladder frame 2, so that the secondary ladder frame 2 rotates away from or folds towards the main ladder frame 1 with the middle part of the main ladder frame 1 as the rotation center, which is convenient for folding and transportation when not in use. A cable steel rope positioning assembly 3 and a safety belt hanging member 4 are provided on the upper part of the main ladder frame 1. Among them, the cable steel rope positioning assembly 3 is used to fix the relative position between the main ladder frame 1 and the ground by using a cable steel rope 32 after the secondary ladder frame 2 is unfolded. If there is a wall that can be relied on at the construction site, after the secondary ladder frame 2 is unfolded, the top of the main ladder frame 1 can be leaned against the wall to increase the stability of the overall structure. It can be seen that by setting the cable steel rope positioning assembly 3, the present utility model can strengthen the main ladder frame 1, prevent it from shaking when the staff climbs the main ladder frame 1, and improve the stability of the overall structure. The safety belt hanging member 4 is arranged on the upper part of the main ladder frame 1. After the staff climbs to a higher position, the safety belt hanging member 4 can change the safety belt on the body to the main ladder frame 1. Since the main ladder frame 1 has been strengthened by the cable steel rope positioning assembly 3, it can ensure the personal safety of the staff during construction.

[0033] Embodiment 2:

[0034] See attached Figures 1 to 4A non-slip ladder for electric power maintenance includes a main ladder frame 1 and a sub-ladder frame 2; the middle part of the main ladder frame 1 is hinged to the top of the sub-ladder frame 2; a cable steel wire positioning assembly 3 and a safety belt hanging member 4 are provided on the upper part of the main ladder frame 1; the cable steel wire positioning assembly 3 is used to fix the relative position between the main ladder frame 1 and the ground by using a cable steel wire 32 after the sub-ladder frame 2 is unfolded; the safety belt hanging member 4 is provided on the upper part of the main ladder frame 1 and is used for detachably cooperating with the safety belt worn by the staff. It can be seen from the above structure that both the main ladder frame 1 and the sub-ladder frame 2 are made of insulating materials to ensure the safety of use. The middle part of the main ladder frame 1 is hinged to the top of the sub-ladder frame 2, so that the sub-ladder frame 2 rotates away from or folds towards the main ladder frame 1 with the middle part of the main ladder frame 1 as the rotation center, which is convenient for folding and transportation when not in use. The cable steel wire positioning assembly 3 and the safety belt hanging member 4 are provided on the upper part of the main ladder frame 1. Among them, the cable steel wire positioning assembly 3 is used to fix the relative position between the main ladder frame 1 and the ground by using the cable steel wire 32 after the sub-ladder frame 2 is unfolded. If there is a wall that can be relied on at the construction site, after the sub-ladder frame 2 is unfolded, the top of the main ladder frame 1 can be leaned against the wall to increase the stability of the overall structure. It can be seen that by setting the cable steel wire positioning assembly 3, the present utility model can strengthen the main ladder frame 1, prevent shaking when the staff climbs the main ladder frame 1, and improve the stability of the overall structure. The safety belt hanging member 4 is provided on the upper part of the main ladder frame 1. After the staff climbs to a higher position, the safety belt hanging member 4 can change the safety belt on the body to the main ladder frame 1. Because the main ladder frame 1 has been strengthened by the cable steel wire positioning assembly 3, the personal safety of the staff during construction can be guaranteed.

[0035] The cable steel wire positioning assembly 3 includes two cable steel wire hanging rings 31 and two cable steel wires 32; the cable steel wire hanging rings 31 correspond to the cable steel wires 32 one by one; the two cable steel wire hanging rings 31 are symmetrically arranged on the top of the main ladder frame 1; the upper end of the cable steel wire 32 is connected to the corresponding cable steel wire hanging ring 31, and the lower end is fixed to the ground. It can be seen from the above structure that the cable steel wire positioning assembly 3 includes two cable steel wire hanging rings 31 and two cable steel wires 32. The two cable steel wires 32 are used for lateral fixation of the main ladder frame 1 to prevent the main ladder frame 1 from shaking and shifting when the staff climbs. The two cable steel wire hanging rings 31 are symmetrically arranged on the top of the main ladder frame 1, which can facilitate the staff to adjust the fixing force on both sides of the main ladder frame 1 during installation to make the forces on both sides consistent.

[0036] The safety belt hanging part 4 includes a horizontal bar 41 and two safety belt hanging rings 42; the two safety belt hanging rings 42 are symmetrically arranged on the front and rear ends of the horizontal bar 41 close to the main ladder frame 1; each safety belt hanging ring 42 is used to detachably cooperate with a hook on the safety belt worn by the staff. From the above structure, it can be seen that the safety belt hanging part 4 includes a horizontal bar 41 and two safety belt hanging rings 42. Since the safety belt worn by the staff generally has two support belts with hooks, when the staff climbs to the top of the main ladder frame 1, the hooks on the body can be replaced with the safety belt hanging rings 42. Because the two safety belt hanging rings 42 are symmetrically arranged on the front and rear ends of the horizontal bar 41 close to the main ladder frame 1, after the replacement, the two support belts can play a positioning and supporting effect for the left and right sides of the staff's body, ensuring the personal safety of the staff during construction.

[0037] The outer side wall of the top of the auxiliary ladder frame 2 is placed on the side where the inner side wall of the main ladder frame 1 is located, and the top of the auxiliary ladder frame 2 is rotatably connected to the middle of the main ladder frame 1 through the pin 5. As can be seen from the above structure, since the height of the main ladder frame 1 is often set to three meters or higher in order to meet the need for climbing, the top of the auxiliary ladder frame 2 is rotatably connected to the middle of the main ladder frame 1 through the pin 5. Under the premise of ensuring the reliability of rotation, the middle of the main ladder frame 1 can also be used as the rotation center, which is convenient for the staff to unfold and fold the auxiliary ladder frame 2.

[0038] The two ends of each pin shaft 5 are matched with limiting members. As can be seen from the above structure, the two ends of the pin shaft 5 are matched with limiting members to limit the displacement of the pin shaft 5 and prevent the pin shaft 5 from slipping.

[0039] The auxiliary ladder frame 2 rotates leftward relative to the main ladder frame 1 and the maximum rotation angle is 30°. From the above structure, it can be seen that the maximum rotation angle of the auxiliary ladder frame 2 relative to the main ladder frame 1 is 30°, which ensures the stability of the overall structure after the auxiliary ladder frame 2 is deployed.

[0040] Embodiment three:

[0041] See attached Figures 1 to 4。A power maintenance anti-slip ladder includes a main ladder frame 1 and a secondary ladder frame 2; the middle part of the main ladder frame 1 is hinged to the top of the secondary ladder frame 2; a cable steel wire positioning assembly 3 and a safety belt hanging piece 4 are provided on the upper part of the main ladder frame 1; the cable steel wire positioning assembly 3 is used to fix the relative position between the main ladder frame 1 and the ground by means of a cable steel wire 32 after the secondary ladder frame 2 is unfolded; the safety belt hanging piece 4 is arranged on the upper part of the main ladder frame 1 and is used for detachably cooperating with the safety belt worn by the staff. From the above structure, it can be seen that both the main ladder frame 1 and the secondary ladder frame 2 are made of insulating materials to ensure the safety of use. The middle part of the main ladder frame 1 is hinged to the top of the secondary ladder frame 2, so that the secondary ladder frame 2 rotates away from or folds towards the main ladder frame 1 with the middle part of the main ladder frame 1 as the rotation center, which is convenient for folding and transporting when not in use. The upper part of the main ladder frame 1 is provided with a cable steel wire positioning assembly 3 and a safety belt hanging piece 4. Among them, the cable steel wire positioning assembly 3 is used to fix the relative position between the main ladder frame 1 and the ground by means of a cable steel wire 32 after the secondary ladder frame 2 is unfolded. If there is a wall that can be relied on at the construction site, after the secondary ladder frame 2 is unfolded, the top of the main ladder frame 1 can be leaned against the wall to increase the stability of the overall structure. It can be seen that by setting the cable steel wire positioning assembly 3, the present utility model can reinforce the main ladder frame 1, prevent shaking when the staff climbs the main ladder frame 1, and improve the stability of the overall structure. The safety belt hanging piece 4 is arranged on the upper part of the main ladder frame 1. After the staff climbs to a higher position, the safety belt hanging piece 4 can replace the safety belt on the body and hang it on the main ladder frame 1. Since the main ladder frame 1 has been reinforced by the cable steel wire positioning assembly 3, the personal safety of the staff during construction can be guaranteed.

[0042] The main ladder frame 1 is provided with a number of horizontally arranged pedals 11; anti-slip pads are provided on the top of each pedal 11. From the above structure, it can be seen that the pedals 11 are used for the staff to step on and climb, and anti-slip pads are provided on the top of each pedal 11, which increases the friction when the staff steps on and climbs and plays an anti-slip role.

[0043] The height difference between every two adjacent pedals 11 is the same, and the height difference range is 30 cm - 40 cm. From the above structure, it can be seen that the height difference between every two adjacent pedals 11 is the same, and the height difference range is 30 cm - 40 cm. The value of the height difference can be adjusted adaptively according to the specific situation, which is convenient for the staff to climb. Specifically, the height difference between two adjacent pedals 11 can be set to 32 cm, 35 cm, 37 cm.

[0044] The height of the main ladder frame 1 is 2 - 2.5 times that of the secondary ladder frame 2. From the above structure, it can be seen that setting the height of the main ladder frame 1 to be 2 - 2.5 times that of the secondary ladder frame 2 is used to ensure the structural stability between the main ladder frame 1 and the secondary ladder frame 2 after the secondary ladder frame 2 is unfolded.

[0045] It further includes eight corner sleeves 6; both the top end and the bottom end of the main ladder frame 1 are provided with two main ladder end brackets extending away from the middle of the main ladder frame 1; the bottom end of the auxiliary ladder frame 2 is provided with two auxiliary ladder end brackets extending downward; a corner sleeve 6 is sleeved on the end of each main ladder end bracket or auxiliary ladder end bracket. It can be seen from the above structure that by providing the corner sleeve 6, the ends of the main ladder end brackets or the auxiliary ladder end brackets can be better protected, wear can be reduced, and the service life of the equipment can be increased.

[0046] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
