Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulated ladder technology, specifically to a portable insulated ladder for electrical work. Background Technology
[0002] Electrical work refers to a series of tasks involving the operation, maintenance, repair, modification, and upgrading of power systems to ensure their normal operation and safety. These tasks include, but are not limited to, the inspection, repair, modification, and upgrading of electrical equipment, aiming to maintain equipment stability and reliability, improve system efficiency and safety, and promote energy conservation and environmental protection. Electrical work requires the support of professional technicians and an efficient work management system. Electrical engineers need to receive specialized training to learn professional knowledge and skills to ensure the safety and stability of the power system. Some electrical equipment is located at high altitudes, requiring the use of ladders for access during work.
[0003] When a ladder is placed at an angle on the ground, forming a triangular structure with a utility pole or wall, the friction between the bottom of the ladder and the ground is relatively low, making it prone to slipping under stress and causing it to collapse. This reduces safety during high-altitude work. To address this issue, a portable insulated ladder for electrical work is proposed, which solves the problem by incorporating a triangular support structure at the bottom of the main ladder.

[0027] Example 1
[0028] Reference Figures 1-3This is the first embodiment of the present invention, which proposes a portable insulated ladder for power operations, including a main ladder 1 and an auxiliary ladder 2. The bottom end of the main ladder 1 is symmetrically and rotatably connected to a first base 3. The crossbeam of the main ladder 1 is symmetrically and fixedly connected to a first locking plate 4. The inside of the first locking plate 4 is rotatably connected to a sleeve rod 5. The inside of the sleeve rod 5 is slidably connected to a telescopic rod 6. One end of the telescopic rod 6 is rotatably connected to a second base 7. A first connecting rod 8 is fixedly connected between the two first bases 3. A second connecting rod 9 is fixedly connected between the two second bases 7. A support rod 10 is snapped between the first connecting rod 8 and the second connecting rod 9. Both ends of the support rod 10 are threaded, and both ends of the support rod 10 are symmetrically threadedly connected to nuts 11. The purpose of this setup is that, when placing the insulated ladder, the main ladder 1 is first placed at an angle on the ground, with the top of the main ladder 1 in contact with the wall or the outer end of the utility pole. At the same time, the sleeve rod 5 inside the first clamping plate 4 is rotated, and the telescopic rod 6 inside the tensioner is stretched, so that the second base 7 is placed parallel to the ground. Then, the support rod 10 is used to pass through the first connecting rod 8 and the second connecting rod 9 and is fixed with the nut 11. At this time, the sleeve rod 5, the telescopic rod 6, the main ladder 1, and the ground are arranged in a triangular structure, which enhances the stability of the main ladder 1 placed on the ground and prevents the main ladder 1 and the auxiliary ladder 2 from sliding and tipping over under the force.
[0029] Optionally, both the bottom ends of the first base 3 and the second base 7 are provided with anti-slip textures, and one end of the sleeve rod 5 is threaded with a fixing ring 12 threaded to the outer end. The purpose of this arrangement is that the anti-slip textures on the bottom of the first base 3 and the second base 7 increase the friction between the main ladder 1 and the ground, preventing the main ladder 1 from sliding under force, and the fixing ring 12 fixes the extension of the telescopic rod 6.
[0030] Example 2
[0031] Reference Figures 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:
[0032] Compared to Embodiment 1, the main ladder 1 has a symmetrically fixed limit plate 13 at its top. The limit plate 13 has an L-shaped cross-section. The auxiliary ladder 2 is located inside the limit plate 13. A connecting plate 14 is fixedly connected inside the first base 3, and the connecting plate 14 is perpendicular to the first base 3. The purpose of this arrangement is to limit the auxiliary ladder 2 with the limit plate 13 to prevent the main ladder 1 and auxiliary ladder 2 from tipping over during use. The connecting plate 14 is designed to ensure that the insulated ladder is parallel to the transport equipment when stored.
[0033] Optionally, clamping columns 15 are symmetrically and fixedly connected to the top crossbeam of the main ladder 1, and the auxiliary ladder 2 is slidably connected to the clamping columns 15. The purpose of this arrangement is to facilitate the sliding of the auxiliary ladder 2 at the outer end of the main ladder 1 by the clamping columns 15.
[0034] Optionally, the top crossbeam of the main ladder 1 is symmetrically and fixedly connected with second clamping plates 16. The two second clamping plates 16 are internally rotatably connected with limiting rings 17, the front end of which is arc-shaped. The purpose of this arrangement is that the limiting rings 17 with arc-shaped front ends can be clamped onto the outer end of the utility pole, thereby preventing the main ladder 1 from tilting or falling over when clamped onto the outer end of the utility pole.
[0035] Optionally, the limiting ring 17 is symmetrically slidably connected with first locking pins 18, and a first spring 19 is fixedly connected between the two first locking pins 18. The outer end of the second locking plate 16 is symmetrically provided with locking holes, and the first locking pins 18 are engaged with the inside of the locking holes. The purpose of this arrangement is to facilitate the engagement of the limiting ring 17 with the inside of the second locking plate 16 by the first locking pins 18 and the first spring 19.
[0036] Optionally, a second locking pin 20 is slidably connected inside the main beam of the main ladder 1, and a second spring 21 is fixedly connected between the main ladder 1 and the second locking pin 20. A positioning hole is provided at the outer end of the limiting plate 13, and the second locking pin 20 is engaged inside the positioning hole. Several groups of the second locking pins 20 are provided and arranged at equal intervals, with two second locking pins 20 in each group. The purpose of this arrangement is to facilitate the fixing of the auxiliary ladder 2 at the sliding position of the main ladder 1, thereby facilitating the adjustment of the length of the insulated ladder.
