DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0018] like Figure 1-4The line operation and maintenance auxiliary equipment shown in the figure comprises two ladder beams 1 and a plurality of pedals 2 connected between the two ladder beams 1, a first sleeve 3 parallel to the pedals 2 is installed at the top of each of the two ladder beams 1, a rotating connecting rod 6 assembly is inserted in the first sleeve 3, the connecting rod 6 assembly rotates around the axis of the first sleeve 3, a second sleeve 4 is installed at one end of the connecting rod 6 assembly away from the first sleeve 3, a clamping assembly is inserted in the second sleeve 4, and the clamping assembly rotates around the axis of the second sleeve 4;

[0019] Based on the above, during the process of line operation and maintenance, climbing work is required, and the ladder composed of the ladder beam 1 and the pedal 2 is placed outside the electric pole of the line, supported and placed, and the user performs climbing work through the ladder beam 1 and the pedal 2;

[0020] Furthermore, since the utility pole is cylindrical, the connecting rod 6 assembly rotating at the top of the ladder beam 1 is used to drive the clamping assembly to move to a suitable position, and then the clamping assembly is adjusted to clamp it on the outside of the cylindrical utility pole, thereby fixing the top end of the operation and maintenance auxiliary ladder and the utility pole to prevent it from slipping during use, thereby improving the safety of users during line operation and maintenance.

[0021] The connecting rod 6 assembly includes a first rotating shaft 5 inserted in the first sleeve 3 and a connecting rod 6 fixed at the end of the first rotating shaft 5, the connecting rod 6 is located on the outside of the ladder beam 1, and two first limiting rings 7 are sleeved on the outside of the first rotating shaft 5, and the two first limiting rings 7 are respectively located at both ends of the first sleeve 3;

[0022] Based on the above, the connecting rod 6 assembly rotates in the first sleeve 3 at the top of the ladder beam 1 through the connecting rod 6 and the first rotating shaft 5 to achieve position and angle adjustment of the connecting rod 6 assembly and the clamping assembly. The first limiting rings 7 on both sides limit the first rotating shaft 5 in the first sleeve 3 to prevent it from falling off.

[0023] The end of the first sleeve 3 located on the inner side of the ladder beam 1 extends inwards for a distance, and a circle of limiting teeth 8 is installed on the outer part of the first sleeve 3 extending inwards;

[0024] Furthermore, when the ladder beam 1 is leaning against the outside of the electric pole, in addition to the clamping assembly for clamping, fixing and limiting, the limiting teeth 8 on the first sleeve 3 will also contact the outer wall of the battery pole, increasing the friction force so that the ladder beam 1 is not easy to slip and shake.

[0025] A first spiral tube 9 is installed on the outer wall of the first sleeve 3. The first spiral tube 9 and the ladder beam 1 are located on the same straight line. A first screw rod 10 that penetrates the first sleeve 3 is inserted into the first spiral tube 9. The bottom end of the first screw rod 10 abuts against the outer wall of the first rotating shaft 5.

[0026] After the connecting rod 6 assembly is rotated through the connecting rod 6 and the first rotating shaft 5 and the angle is adjusted, the first screw 10 is rotated so that its end is against the outer wall of the first rotating shaft 5, and the first rotating shaft 5 is fixed in the first screw tube 9, so as to fix the connecting rod 6 and the clamping assembly part to avoid deviation and shaking when it is leaning against the outside of the pole.

[0027] The second sleeve 4 is fixed to the other end of the connecting rod 6, and the clamping assembly includes a second rotating shaft 11 inserted in the second sleeve 4 and a clamping plate 12 fixed to the end of the second rotating shaft 11. The clamping plate 12 rotates in the second sleeve 4 through the second rotating shaft 11, and a row of clamping protrusions 16 are installed at the edge of the clamping plate 12;

[0028] Based on the above, after the connecting rod 6 assembly is adjusted, the second rotating shaft 11 is rotated in the second sleeve 4 to achieve angle adjustment of the clamping plate 12 at the end of the connecting rod 6, so that an inclined angle is formed between the clamping plate 12 and the connecting rod 6 and the ladder beam 1. When the ladder beam 1 is leaning against the outside of the electric pole, the limiting teeth 8 on the first sleeve 3 at the top of the ladder beam 1 are stuck on the outer wall of the electric pole, and the clamping plate 12 will also fit against the outer wall of the electric pole after tilting. The friction force is increased by the two on the outside of the electric pole, so that the top of the ladder beam 1 is not easy to slip after leaning against it, thereby improving safety.

[0029] Two second limiting rings 13 are sleeved on the outside of the second rotating shaft 11, and the two second limiting rings 13 are respectively located at two ends of the second sleeve 4;

[0030] The two second limiting rings 13 limit the second rotating shaft 11 in the second sleeve 4 to prevent the second rotating shaft 11 from falling out of the second sleeve 4 .

[0031] A second spiral tube 14 is installed on the outer wall of the second sleeve 4. The second spiral tube 14 is located outside the ladder beam 1 and is perpendicular to the connecting rod 6 at 90 degrees. A second screw 15 that passes through the second sleeve 4 is inserted into the second spiral tube 14. The end of the second screw 15 is against the outer wall of the second rotating shaft 11.

[0032] After the angle of the clamping plate 12 is adjusted, the second screw 15 is rotated in the second screw tube 14 to press the second screw 15 against the outer wall of the second rotating shaft 11, so that the angle between the clamping plate 12 and the connecting rod 6 is fixed, and the two clamping plates 12 on the ladder beam 1 on both sides form a clamping state, and the ladder beam 1 is clamped and fixed when it is leaning against the electric pole.

[0033] The second screw rod 15 is located outside the ladder beam 1 and is perpendicular to the connecting rod 6 so that it can be staggered with the inner wire rod.

[0034] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
