DETAILED DESCRIPTION

[0025] The present invention provides Figure 1 to Figure 7A new type of large-span electric steel pipe pole shown in the figure includes a main pole body 1, which is arranged in multiple numbers. The multiple main pole bodies 1 are connected in sequence from bottom to top, and the bottom of a main pole body 1 located at the bottom position is fixedly connected to a base 25, which is convenient for the installation of the electric steel pipe pole. The main pole body 1 is made of high-strength steel material and can meet the large span requirements.

[0026] The electric power steel pipe pole is assembled in an assembling manner, which increases the flexibility of use and the convenience of transportation. When used specifically, a suitable number of main pole bodies 1 can be selected.

[0027] In order to facilitate climbing to a higher position of the electric steel pipe pole during power construction, a cross bar 2 is fixedly connected to the outer wall of the main pole body 1, and a vertical frame 3 is fixedly connected to one end of the cross bar 2 away from the main pole body 1. The vertical frames 3 are distributed along the height direction of the main pole body 1, and the cross bar 2 can be provided in multiple numbers to improve the use strength of the vertical frames 3. A plurality of supporting square tubes 6 for stepping on are fixedly connected to the outer wall of the vertical frame 3, and the plurality of supporting square tubes 6 extend to both sides one by one in sequence along the height direction of the vertical frame 3. The vertical frame 3 and the plurality of supporting square tubes 6 form a ladder structure for operators to climb to a higher position of the electric steel pipe pole during power construction.

[0028] At the same time, when the plurality of main rod bodies 1 are connected in sequence from bottom to top, the plurality of vertical frames 3 are also connected in sequence from bottom to top to form a continuous ladder structure.

[0029] Taking into account that construction workers will use safety belts during the climbing process, in order to cooperate with the safety belts, a slide groove 4 is opened on the side of the vertical frame 3 facing away from the main pole body 1, and the slide groove 4 runs through the upper and lower surfaces of the vertical frame 3, so that when multiple vertical frames 3 are connected in sequence from bottom to top, multiple slide grooves 4 can be connected, and a slider 5 for cooperating with the safety belt is slidingly provided inside the slide groove 4, and the slider 5 can slide back and forth between the multiple slide grooves 4.

[0030] The slider 5 is fixedly connected with a protrusion 16, and a circular groove 17 is formed on the protrusion 16. A cylinder 19 is arranged below the protrusion 16, and a safety rope 18 is passed through the cylinder 19. The top of the safety rope 18 passes through the circular groove 17 and is fixedly connected to the protrusion 16. The bottom of the safety rope 18 is fixedly connected with a docking ring 23, and the docking ring 23 docks with the safety belt. When in use, the safety belt is worn by construction workers. When the construction workers climb up and down, the safety belt drives the slider 5 to slide through the safety rope 18 and the protrusion 16.

[0031] In order to improve the stability of the slider 5 sliding in the slide groove 4, the slide groove 4 and the slider 5 are both T-shaped. In specific use, a structure such as a ball (not shown in the figure) can also be set outside the slider 5 to improve the smoothness of the slider 5 sliding in the slide groove 4.

[0032] Considering that when the electric steel pipe pole is used, when birds stay on the supporting square tube 6, bird droppings are likely to remain and harden, which will bring the potential safety hazard of slipping, especially when it is stained with fog and water, in order to achieve convenient cleaning, a round hole is penetrated and opened at the end of the supporting square tube 6 away from the main rod body 1, and a slide bar 8 is slidably arranged inside the round hole, and a square groove 7 is opened on the side wall of the vertical frame 3 for the slide bar 8 to extend into the inside of the slide groove 4. When the slide bar 8 extends into the inside of the slide groove 4 from the square groove 7, the slide groove 4 can be partitioned. When the construction personnel accidentally fall, the safety belt drives the slider 5 to slide downward. At this time, the slide bar 8 can realize the function of limiting, so that the slider 5 cannot continue to slide downward inside the slide groove 4, thereby ensuring the working safety of the construction personnel.

[0033] To facilitate the control of the movement of the slide bar 8, an outer plate 9 is fixedly connected to the end of the slide bar 8 away from the vertical frame 3, an L-shaped plate 14 is fixedly connected to the outer plate 9, a scraper 15 is fixedly connected to the L-shaped plate 14, the scraper 15 and the L-shaped plate 14 are distributed in a U shape, and the scraper 15 is attached to the upper surface of the supporting square tube 6.

[0034] When the outer plate 9 drives the slide bar 8 to slide outward (i.e., in the direction away from the vertical frame 3), the partition of the slide groove 4 stops, allowing the slider 5 to move up and down, so that the construction workers can drive the slider 5 to slide inside the slide groove 4 through the safety belt without affecting climbing; in this process, the outer plate 9 drives the scraper 15 through the L-shaped plate 14 to push and scrape the upper surface of the supporting square tube 6 to scrape off foreign matter such as bird droppings, thereby avoiding slipping during the climbing process, and the operation is convenient without the need to use additional tools.

[0035] The top of the outer plate 9 is higher than the upper surface of the supporting square tube 6, which is convenient for construction workers to push the outer plate 9 with their feet when stepping on the supporting square tube 6. At the same time, they can also push the outer plate 9 with their hands, which increases the flexibility of use.

[0036] In addition, after the outer plate 9 and the slide bar 8 are reset, the scraper 15, the L-shaped plate 14 and the supporting square tube 6 form a square-shaped supporting structure for construction workers to step on, thereby expanding the stepping area and improving the climbing stability.

[0037] In order to facilitate the automatic resetting of structures such as the outer plate 9 and the sliding rod 8, a square plate 13 is slidingly arranged inside the supporting square tube 6. The square plate 13 is fixedly connected to the sliding rod 8. A second spring 24 is arranged on the side of the square plate 13 close to the outer plate 9. The second spring 24 is sleeved on the outside of the sliding rod 8. One end of the second spring 24 is fixedly connected to the square plate 13, and the other end of the second spring 24 is fixedly connected to the inner wall of the supporting square tube 6.

[0038] When the outer plate 9 drives the slide bar 8 to slide outward, the square plate 13 squeezes the second spring 24 to contract; when the outer plate 9 is released, the restoring elastic force of the second spring 24 drives the outer plate 9, the slide bar 8 and other structures to automatically reset through the square plate 13.

[0039] The present invention is provided with structures such as a supporting square tube 6, a sliding rod 8 and a scraper 15. The outer plate 9 drives the scraper 15 through the L-shaped plate 14 to push and scrape the upper surface of the supporting square tube 6 to remove foreign matter such as bird droppings, thereby avoiding slipping during the climbing process. The operation is convenient and no additional tools are required. At the same time, the sliding rod 8 can realize the function of limiting, thereby ensuring the working safety of the construction personnel and improving the use efficiency of the electric steel pipe pole.

[0040] In order to improve the stability of the slider 5, the end of the slide bar 8 away from the outer plate 9 is fixedly connected to an arc rod 10, and the top of the arc rod 10 is concave, which is convenient for limiting the slider 5 sliding from top to bottom. The end of the arc rod 10 away from the slide bar 8 is fixedly connected to an insertion rod 11, and the inner wall of the slide groove 4 is provided with a slot 12 for the insertion rod 11 to be inserted.

[0041] When the outer plate 9 drives the slide bar 8 to slide outward (i.e., in the direction away from the vertical frame 3), the slide bar 8 drives the arc rod 10 and the slide bar 8 to move synchronously, and the arc rod 10 and the slide bar 8 are all recovered to the inside of the supporting square tube 6, so that the construction personnel can drive the slider 5 to slide inside the slide groove 4 through the safety belt without affecting climbing; and when the outer plate 9 is released, the reset elastic force of the second spring 24 drives the outer plate 9, the slide bar 8 and other structures to automatically reset through the square plate 13, and the insertion rod 11 is inserted into the inside of the slot 12 to form a stable limiting structure.

[0042] Considering that the safety rope 18 usually lacks a buffering function, once the construction workers accidentally fall, a large instantaneous impact force will be generated, which may easily cause injuries to the construction workers. The safety rope 18 is fixedly connected to the top of the cylinder 19, and a round block 21 is slidingly arranged inside the cylinder 19, and the safety rope 18 passes through the round block 21, and the round block 21 is fixedly connected to the safety rope 18. A buffer chamber 22 is formed between the round block 21 and the top of the cylinder 19, and in a natural state, the safety rope 18 is curved inside the buffer chamber 22, and a first spring 20 is arranged inside the buffer chamber 22. The first spring 20 surrounds the outside of the safety rope 18, one end of the first spring 20 is fixedly connected to the round block 21, and the other end of the first spring 20 is fixedly connected to the inner wall of the top of the cylinder 19, and the elastic supporting force of the first spring 20 is appropriate. When the construction workers climb up and down, the safety belt drives the slider 5 to slide through the safety rope 18 and the protrusion 16, and at this time the first spring 20 will not stretch at will.

[0043] Specifically, if a construction worker accidentally falls, the bottom end of the safety rope 18 will be pulled through the safety belt and the docking ring 23, thereby driving the round block 21 to slide downward inside the cylinder 19 and stretching the first spring 20. The first spring 20 performs shock absorption and buffering to reduce the impact force on the construction worker.
