[0048] Embodiment 1:

[0049] In the prior art, when performing electrical construction or electrical maintenance, the pole climbing ladder device generally has a chuck or a clamp to fix the pole climbing ladder device on the utility pole. However, since the chuck or the clamp is only provided on one side of the ladder, its stability is not high, and safety problems are likely to occur, resulting in casualties.

[0050] To solve the above problems, this embodiment provides a pole climbing ladder device, which can increase the stability of the connection between the pole climbing ladder device and the utility pole and improve the safety of the staff when using the pole climbing ladder device. Specifically, as Figure 1 shown, the pole climbing ladder device includes a ladder mechanism 10 and multiple groups of fixing mechanisms 20. The ladder mechanism 10 includes two columns 11 and multiple support plates 12 arranged at intervals in the vertical direction between the two columns 11. The staff can hold the columns 11 by hand and step on the support plates 12 to climb upward; multiple groups of fixing mechanisms 20 are arranged at intervals in the vertical direction on one side of the ladder mechanism 10. The fixing assembly includes a first arm component 21 and a second arm component 22. The first arm component 21 and the second arm component 22 are respectively arranged on the two columns 11, and the first arm component 21 and the second arm component 22 are arranged in an interleaved manner. Both the first arm component 21 and the second arm component 22 can be sleeved on the utility pole, which can stably fix the two columns 11 of the ladder mechanism 10 to the utility pole in multiple directions and improve the stability of the pole climbing ladder device.

[0051] With the above structure, when it is necessary to repair the electricity on the utility pole, first, the interleaved first arm component 21 and second arm component 22 are sleeved on the utility pole. By providing multiple groups of fixing mechanisms 20 and arranging the first arm component 21 and the second arm component 22 in an interleaved manner in the vertical direction on the two columns 11 respectively, the first arm component 21 fixes one column 11 to the utility pole, and the second arm component 22 fixes the other column 11 to the utility pole, and the interleaved arrangement improves the stability of the connection between the pole climbing ladder device and the utility pole; then, the staff climbs upward to the top of the ladder mechanism 10 through multiple support plates 12 arranged at intervals in the vertical direction and sits on the seat mechanism 30, and then can safely carry out construction. The operation is simple and the stability is high, improving the safety of the staff during maintenance.

[0052] Furthermore, as Figure 1 shown, the widths of multiple said support plates 12 increase successively from top to bottom in the vertical direction, which is convenient for the staff to climb more labor - saving. Optionally, multiple support plates 12 are all rotatably arranged between two columns 11. After the staff completes construction or maintenance, the support plates 12 can be rotated to facilitate the storage of this pole climbing ladder device. Optionally, anti - slip pads are provided at the bottoms of the two columns 11, which can increase the friction with the ground, avoid the sliding of this pole climbing ladder device on the ground and cause harm to the staff, and improve the stability of this pole climbing ladder device.

[0053] In this embodiment, as Figures 2 to 5 shown, the above - mentioned first arm - holding assembly 21 includes a fixed arm 211 and a sliding arm 212. One end of the fixed arm 211 is fixedly connected to the column 11, and the other end is an arc - shaped structure; the sliding arm 212 is an arc - shaped structure. One end of the sliding arm 212 is slidably connected to the fixed arm 211, and the other end can be joined or separated from the other end of the fixed arm 211. The arc - shaped design can fit the telegraph pole. And when power construction needs to be carried out, the fixed arm 211 is fitted to the telegraph pole, and the sliding arm 212 slides out relative to the fixed arm 211, so that the sliding arm 212 and the fixed arm 211 can enclose a circular - ring - shaped structure, and then the first arm - holding assembly 21 is sleeved and fixed on the telegraph pole. When the power construction is completed and this pole climbing ladder device needs to be stored, when the sliding arm 212 slides back relative to the fixed arm 211, the sliding arm 212 and the fixed arm 211 can be opened, and this pole climbing ladder device can be removed for convenient storage.

[0054] Optionally, as Figure 5 and Figure 6 shown, the sliding arm 212 includes a connecting portion 2121 and an extending portion 2122. The connecting portion 2121 is slidably connected to one end of the fixed arm 211, and the extending portion 2122 is connected to the connecting portion 2121. And the extending portion 2122 can slide in the direction away from one end of the fixed arm 211 along with the connecting portion 2121, so that the end of the extending portion 2122 away from the connecting portion 2121 fits the other end of the fixed arm 211, and a circular - ring - shaped structure can be formed by the fixed arm 211 and the connecting arm, which can better enclose and fix the telegraph pole.

[0055] Further optionally, as Figure 5 and Figure 6As shown, the connecting part 2121 is provided with gear teeth 21211. The first arm component 21 further includes a gear 23. The gear 23 is rotatably arranged in the fixed arm 211 and meshes with the gear teeth 21211, enabling a sliding connection between the connecting part 2121 and the fixed arm 211. Optionally, there are multiple gear teeth 21211, increasing the length of the sliding displacement between the connecting part 2121 and the fixed arm 211.

[0056] Furthermore, as Figure 5 shown, a limiting member 24 is provided at one end of the sliding arm 212 facing the fixed arm 211. The limiting member 24 can abut against the gear 23, so that when the sliding arm 212 slides on the fixed arm 211 until the limiting member 24 abuts against the gear 23, its sliding in this direction can be stopped, thereby realizing the limitation of the sliding arm 212.

[0057] Still further, as Figures 2 to 4 shown, the fixed arm 211 includes a fixed part 2111 and an arm part 2112. The fixed part 2111 is fixedly connected to the column 11, and the arm part 2112 is connected to the fixed part 2111. The arm part 2112 has an arc-shaped structure and can fit with the electric pole. Optionally, the fixed part 2111 is provided with an inner cavity 21111. The gear 23 is rotatably arranged in the inner cavity 21111 of the fixed part 2111 and meshes with the gear teeth 21211 of the sliding arm 212, thereby realizing the sliding connection between the fixed arm 211 and the sliding arm 212.

[0058] Optionally, as Figure 7 shown, the cross-section of the arm part 2112 is a triangular ring, and the cross-section of the sliding arm 212 is a triangle. The triangle can slide in the triangular ring, realizing the sliding and storage of the sliding arm 212 and the fixed arm 211. It can be understood that the cross-sections of the arm part 2112 and the sliding arm 212 can change adaptively, and no specific limitation is made here.

[0059] Furthermore, as Figures 2 to 4 shown, the first arm component 21 further includes an anti-slip member 25. The anti-slip member 25 is arranged on the inner ring of the fixed arm 211, which can increase the friction between the fixed arm 211 and the electric pole, prevent relative sliding between the fixed arm 211 and the electric pole, and improve the safety of the electric pole climbing ladder device.

[0060] Furthermore, as Figure 1 and Figure 5As shown, the first arm component 21 further includes a driving member 213. The driving member 213 drives and is connected to the gear 23, which can realize the driving of the first arm component 21. Optionally, the fixing component further includes a control component, which can realize the remote control of the driving of the driving member 213, which is convenient and fast. It can be understood that the structure for the control component to remotely control the driving of the driving member 213 can adopt the commonly used structure in the current technology and will not be elaborated here.

[0061] In this embodiment, the first arm component 21 and the second arm component 22 have the same structure, which reduces the manufacturing cost and is convenient for manufacturing. Therefore, the second arm component 22 will not be elaborated further.

[0062] In this embodiment, as Figure 1 shown, the pole climbing ladder device further includes a seat mechanism 30. The seat mechanism 30 is arranged above the climbing ladder mechanism 10 and is detachably connected to the climbing ladder mechanism 10, which is convenient for the staff to carry out construction and maintenance, saving time and effort, and being detachably connected, which is convenient for storage.

[0063] Optionally, as Figure 1 shown, the seat mechanism 30 includes a fixing member 31 and a seat cushion 32. The fixing member 31 has an L-shaped structure. One end of the fixing member 31 is detachably connected to the climbing ladder mechanism 10, and the seat cushion 32 is arranged above the fixing member 31, which is convenient for the staff to carry out construction and maintenance, saving time and effort, and being detachably connected, which is convenient for storage. Preferably, there are two fixing members 31, and the two fixing members 31 are respectively detachably connected to the two columns 11, which increases the connection stability between the seat mechanism 30 and the climbing ladder mechanism 10.

[0064] Optionally, the fixing member 31 includes a vertical portion and a horizontal portion. The vertical portion is detachably connected to the climbing ladder mechanism 10, and the seat cushion 32 is arranged above the horizontal portion. Optionally, the vertical portion is a ring structure, and the top of the column 11 is also a ring structure. By directly inserting the vertical portion into the column 11 and then fixing it through fasteners passing through the vertical portion and the column 11. Preferably, the vertical portion and the horizontal portion can also be designed to be rotatably connected, which can be rotated and fixed during use so that the horizontal portion and the vertical portion are perpendicular, and when storing, the horizontal portion and the vertical portion can be in a horizontal state, which is convenient for storage.

[0065] Further optionally, as Figure 8 shown, the seat cushion 32 is an arc-shaped structure, which is designed to fit the human body, and the arc-shaped structure increases the use area, so that there is a certain space for the staff to climb from the climbing ladder mechanism 10 to the seat mechanism 30, avoiding the staff hitting the seat mechanism 30. Preferably, in this embodiment, the seat cushion 32 is an arc-shaped structure greater than 90° and less than 180°, which is the best choice and increases the use area.

[0066] Further, as Figure 1As shown, the seat assembly further includes a backrest 33, which is disposed at one end of the horizontal portion away from the vertical portion and is higher than the seat cushion 32. After working for a long time, the staff can lean on the backrest 33 to rest.

[0067] In this embodiment, when performing electrical construction or maintenance, the staff takes out this pole climbing ladder device, rotates the support plate 12 to an angle at which the staff can step on it and then fixes it. Then, the vertical portion and the horizontal portion in the seat assembly are rotated to a vertical state and fixed above the ladder mechanism 10, thus completing the assembly of the pole climbing ladder device. Then, the fixed arms 211 of the first arm assembly 21 and the second arm assembly 22 arranged alternately are attached to the utility pole, and the sliding arms 212 slide out of the fixed arms 211 along the gears 23, so that the sliding arms 212 and the fixed arms 211 enclose a circular ring structure, which is stably sleeved on the utility pole. Moreover, multiple first arm assemblies 21 and second arm assemblies 22 are used to sleeve and fix the utility pole, improving the connection stability between the pole climbing ladder device and the utility pole. The staff steps on the support plate 12 and climbs to the seat mechanism 30, and can sit on the seat cushion 32 to perform electrical construction and maintenance. After the staff completes the electrical construction or maintenance, separate it from the utility pole and restore it to its original state, then the storage of the pole climbing ladder device can be completed, which is convenient to carry.

[0068] Embodiment Two:

[0069] This embodiment provides a pole climbing ladder device. The difference between this embodiment and Embodiment One is that in this embodiment, the fixing member 31 further includes a first telescopic member. One end of the first telescopic member is connected to the ladder mechanism 10, and the other end is connected to the seat cushion 32, which can adjust the distance between the seat cushion 32 and the ladder mechanism 10 in the vertical direction, increasing the working range of the staff during electrical construction and maintenance.

[0070] Furthermore, the fixing member 31 further includes a second telescopic member. One end of the second telescopic member is connected to the first telescopic member, and the other end is connected to the seat cushion 32, which can realize the adjustment of the distance between the seat cushion 32 and the ladder mechanism 10 in the horizontal direction, increasing the working range of the staff during electrical construction and maintenance.
