Description

TECHNICAL FIELD

[0001] The present application relates to a long annular anti-skid footrest of a tower ladder head, belonging to the technical field of electric power towers. BACKGROUND

[0002] Electric power towers are tower-like structures for power transmission, mainly composed of angle steels, connecting plates and bolts. The tower body is usually provided with a ladder for power workers to climb to the tower for maintenance. The main body of the ladder is a steel pipe fixed vertically on the tower, and horizontal arranged stepping rods (also known as ladder nails) are alternately welded on both sides of the steel pipe, and workers climb the tower by climbing these stepping rods.

[0003] In actual use, due to the large height of the electric power tower, workers often need to rest temporarily by using the stepping rods during climbing. However, the existing stepping rods are generally cylindrical steel rods with small diameters, which results in limited contact area between the feet and the stepping rods when standing, and long-time bearing easily causes local pressure discomfort, i.e. "foot pain" phenomenon. In addition, the friction between the cylindrical rod surface and the sole is insufficient, especially in rainy, frosty or oily conditions, and slipping easily occurs when stepping, which brings great safety hazards of falling from a high altitude.

[0004] The existing Chinese utility model patent with publication number CN212867380U discloses an outdoor electric power tower ladder, which comprises a steel pipe, the surface of the steel pipe is movably connected with the inner wall of a U-shaped sleeve, the surface of the U-shaped sleeve is provided with a bolt, the surface of the steel pipe is movably connected with a gasket, one end of the bolt close to the gasket penetrates through the steel pipe and is movably connected with the inner wall of the gasket, the surface of the bolt is threadedly connected with the inner wall of a nut, one side of the surface of the nut close to the gasket is movably connected with the surface of the gasket, the surface of the U-shaped sleeve is fixedly connected with a square block, one side of the surface of the square block away from the U-shaped sleeve is fixedly connected with a square ring, the inner wall of the square ring is fixedly connected with a horizontal rod, the top of the square ring and the horizontal rod are both provided with anti-skid lines, the surface of the horizontal rod is fixedly connected with a fixed rod, one side of the surface of the fixed rod close to the square ring is fixedly connected with the inner wall of the square ring, and the top of the fixed rod is fixedly connected with an anti-skid strip.

[0019] Example 1 like Figure 1As shown, the iron tower 12 climbing ladder of the present invention includes: a ring foot pedal 1, which is U-shaped. The two stepping areas of the ring foot pedal 1 are respectively provided with anti-slip patterns 2 and anti-slip teeth. The ends and the head of the ring foot pedal 1 are designed to curve upwards to achieve external anti-slip protection. After the ring foot pedal 1 is welded, it forms a closed long ring, providing a hook point for safety belts and safety hooks. The lower part of the anti-slip teeth is fixedly connected to the ring foot pedal 1 with inclined teeth 3. The inclination angle of the teeth 3 from one fixed end to the other is 1.5-3°. The top of the teeth 3 is evenly distributed with several... The dry teeth 4 are reinforced with double rows of anti-slip teeth to further enhance foot slip resistance. The teeth 3 of the anti-slip teeth are inclined towards the center of the climbing pole to prevent lateral slippage. The anti-slip texture 2 is an elliptical protrusion that is evenly distributed on the ring foot pedal 1 to increase the anti-slip resistance of the feet and hands. A crossbar 5 is fixedly connected to the inner side of the ring foot pedal 1 near the upturned end. Since the head of the ring foot pedal 1 is upturned, the safety hook will slide down towards the iron tower 12, and people will easily step on the safety hook when climbing. Therefore, a closed space is set at the head of the crossbar 5 to hold the safety hook and prevent it from sliding into the stepping area.

[0020] Example 2 like Figures 2-4As shown, unlike Embodiment 1, the annular foot pedal 1 in this embodiment is equipped with a rope collection device near the upturned end. Since it is inconvenient to attach the safety hook when the head is upturned, it can be attached closer to the head. Then, the collection device pushes the safety hook towards the head and prevents the safety hook from sliding into the foot area. The rope collection device includes two sliding rings 11 slidably connected to the two rods of the annular foot pedal 1. A collection rod 6 is fixedly connected between the two sliding rings 11. A steel cable 7 is fixedly connected to the middle of the collection rod 6. The other end of the steel cable 7 passes through the inner side of the upturned end of the annular foot pedal 1 and slides inside the annular foot pedal 1. The bottom of the foot area of ​​the annular foot pedal 1, which is provided with anti-slip texture 2, has a hole corresponding to the steel cable 7. The end of the steel cable 7 extends out of the hole and is fixedly connected to a pull rod 8. After the attachment is completed, by pulling the pull rod 8, the pull rod 8 drives the internal steel cable 7 to move, thereby driving the steel cable 7 to move. The fixed connection collection rod 6 moves towards the upturned head, keeping the safety hook away from the stepping area and preventing it from slipping and affecting personnel stepping on it. The inner diameter of the slip ring 11 is larger than the diameter of the two rods of the ring foot pedal 1. Since the head of the ring foot pedal 1 is upturned, sufficient space is needed for the collection rod 6 to move. A tension spring 9 is provided between the pull rod 8 and the ring foot pedal 1. After the pull rod 8 is pulled to complete the collection of the safety hook, the tension spring 9 returns to its original position due to its elasticity, making it easy to use next time. The ring foot pedal 1 is rotatably connected to a pulley 10 corresponding to the steel cable 7. Since the steel cable needs to move inside the ring foot pedal 1, the pulley 10 at the bend can reduce the wear on the steel cable 7, thereby extending its service life. The ring foot pedal 1 is tilted upward by 1-3° during welding, so that when personnel step on it, they will slide towards one end of the ring foot pedal 1 and tilt towards the center of the iron tower 12, preventing lateral outward slippage.

[0021] Example 3 like Figures 5-7As shown, the positioning welding auxiliary device of the present invention includes a left half-hoop 13 and a corresponding right half-hoop 14. A lifting rod 15 is fixedly connected to the right half-hoop 14. Two positioning rods 16 are provided at the bottom of the lifting rod 15. The bottom of the two positioning rods 16 is respectively provided with a semi-circular positioning notch and a trapezoidal positioning notch. A groove 17 is provided at the end of the lifting rod 15. A column 18 is provided in the groove 17. An open lifting strap 19 is sleeved on the column 18. The lifting strap 19 is detachable. The two ends of the lifting strap 19 are fixedly connected by positioning buckles. Multiple positioning buckles are provided, and each... The positioning buckles are graduated to prevent the annular foot pedal 1 from tilting off-parallel to the ground during welding positioning. The welding auxiliary device ensures the welding position is accurate. In use, it is fixed to the iron tower 12 by the left half-hoop 13 and the corresponding right half-hoop 14. Then, the grooves 17 at the bottom of the two positioning rods 16 correspond to the two stepping areas of the annular foot pedal 1 to determine the angle. Finally, the sling 19 at the end of the lifting rod 15 passes through the head of the annular foot pedal 1 and is connected by the positioning buckles. Then, the welding end of the annular foot pedal 1 is abutted against the iron tower 12 for welding. The worker presses down on the annular foot pedal 1 between the positioning rod 16 and the sling 19, and simultaneously presses it against the iron tower 12 to achieve welding positioning. The left half hoop 13 and the right half hoop 14 are each equipped with a fixing block 20, and the fixing block 20 is threaded with a fixing bolt 21. The left half hoop 13 and the right half hoop 14 are equipped with fixing components. The split left half hoop 13 and the right half hoop 14 can be fixed by the fixing components according to the iron tower 12 of different diameters after connection. The adjustment is made to accommodate the installation of iron towers 12 of different diameters; the fixing component includes fastening bolts 22 that are threadedly connected to the left half hoop 13 and the right half hoop 14 respectively. The fastening bolts 22 pass through the left half hoop 13 and the right half hoop 14. A clamping block 23 is provided at one end inside the left half hoop 13 and the right half hoop 14. By rotating each fastening bolt 22, the clamping block 23 is moved toward the iron tower 12 and abuts against it for fixation; the clamping block 23 is spherical and threadedly connected to the fastening bolt 22. The clamping block 23 is made of wear-resistant rubber material.

[0022] The foot pedal of this invention is a closed long ring, which can provide a hook point for safety belts and safety hooks; the head is designed to tilt upwards to achieve external blocking and anti-slip; the front ring is added with anti-slip texture 2 to increase the anti-slip of the feet and hands; the rear ring is added with double rows of anti-slip teeth to further increase the anti-slip of the feet; the anti-slip teeth are inclined towards the center of the climbing pole to prevent lateral outward slipping; the double-row load-bearing design greatly increases the width of the foot pedal.
