It is a supporting structure for overhead transmission lines to support conductors and lightning conductors, so that the conductors meet the distance requirements from the ground and objects, and can withstand the loads of conductors, lightning conductors, their own loads and external loads. It is often used to support and carry the tower structure of transmission lines.

[0003] At present, common steel pipe tower structures are usually not equipped with auxiliary ladders. Maintenance personnel often rely on the climbing equipment they carry to complete maintenance tasks during operation.

DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0022] See also Figure 1-3 The present embodiment relates to an electric steel pipe tower with an auxiliary ladder 1, including a tower body 100 and an auxiliary ladder 1 installed on its outside, the auxiliary ladder 1 including a frame body 11 and a plurality of cross bars 12 connected between the frame bodies 11 on both sides thereof, the frame body 11 is provided with a sliding bar 2 of an adapted size, the sliding bar 2 is slidably provided with a connecting seat 3, the connecting seat 3 is hinged with a connecting rod 31 and a holder 32 of an adapted size of the sliding rod 2 is provided inside, the connecting rod 31 is connected to the holder 32 via a support rod 33 provided on the connecting seat 3, one end of the support rod 33 is hinged with the holder 32 inside the connecting seat 3, and the other end is slidably provided on the connecting rod 31 and is at a certain angle.

[0023] Specifically in this embodiment, Figure 1 As shown, when the maintenance personnel climb up along the tower body 100 through the auxiliary ladder 1, they can connect the safety belt buckle structure after wearing it with the adapter connecting rod 31 provided on the connecting seat 3 shown in the figure in the early stage of climbing. The specific structure of the connecting seat 3 can be seen in Figure 2-3As shown, after ensuring that the safety belt is connected stably and climbing up along the tower body 100 through the several cross bars 12 connected to the two sides of the auxiliary ladder 1 frame body 11, due to the deadweight of the connecting seat 3, the connecting rod 31 is driven by the human body through the safety belt to rotate upward on the connecting seat 3 at an appropriate angle. At the same time, the connecting rod 31 can slide at a corresponding angle along the guide groove 34 with an appropriate length on the connecting seat 3, and drive the support rod 33 slidably connected to the connecting rod 31 below to slide at an appropriate angle along the slide groove 311 with a certain length on the connecting rod 31 and move upward. During the upward movement of the support rod 33, the card seat 32 hinged to the other end of the connecting seat 3 can be driven to move to an appropriate position The lower connecting seat 3 connected by the safety belt can slide upward along the slide bar 2 provided on the frame 11 of the auxiliary ladder 1 under the drive of the human body during the upward climbing process. When the maintenance personnel climb to the working height and need to change the binding position of the safety belt, they can pull the safety belt to make the connecting seat 3 slide upward along the slide bar 2 to a suitable position to facilitate the untying of the safety belt and the replacement of the working position, so as to carry out subsequent maintenance processes at different working positions on the tower body 100. At the same time, the connecting seat 3 disconnected from the safety belt, its connecting rod 31 can rotate downward along the connecting seat 3 under the action of gravity and slide downward along the guide groove 34 to a certain distance, and the connecting rod 32 can rotate downward along the connecting seat 3 under the action of gravity and slide downward along the guide groove 34 to a certain distance, and the connecting rod 32 can slide downward along the guide groove 34 to a certain distance, and the connecting rod 32 can slide downward along the guide groove 34 to a certain distance, and the connecting rod 32 can slide downward along the slide bar 2 ... The connecting rod 31 can drive the lower support rod 33 to rotate to a certain angle on the inner seat 32 of the connecting seat 3 during the rotation process, and slide in the slide groove 311 on the connecting rod 31 to a certain distance and then move downward. The downward movement of the supporting rod 33 can drive the seat 32 hinged thereto to move to an appropriate position on the connecting seat 3 and fit with the slide bar 2, so that the connecting seat 3 stops sliding and remains stationary at the corresponding maintenance operation position, so as to facilitate the maintenance personnel to repeatedly bind the safety belt after the operation is completed. Specifically, when the maintenance personnel descend along the auxiliary ladder 1 on the tower body 100, the above steps can be repeated, that is, the connecting rod 31 on the connecting seat 3 is pulled so that the connecting seat 3 slides downward along the slide bar 2 under the action of its own gravity, so that the connecting seat 3 stops sliding and remains stationary at the corresponding maintenance operation position. The redundant length of the safety belt connected to the seat 3 is straightened and tightened. According to the specific descending position of the maintenance personnel, the connecting seat 3 placed obliquely below the human body slides downward along the slide bar 2 on the auxiliary ladder 1 frame 11 until it reaches the bottom of the slide bar 2, so as to realize the maintenance personnel to keep the safety belt stably connected during the climbing and descending process. When the maintenance personnel slip or even fall due to physical reasons or the influence of uncertain factors such as the external environment and weather during the climbing or descending process, the connecting rod 31 on the connecting seat 3 connected to the safety belt is subjected to a downward pulling force during the sudden descent of the human body under the action of gravity, so that the above steps are repeated to fit the clamping seat 32 with the slide bar 2 so that the sliding connecting seat 3 on the slide bar 2 stops sliding immediately.In order to stop the continuous descent process of the maintenance personnel and ensure the personal safety of the maintenance personnel, the structural design of the connecting seat 3 on the auxiliary ladder 1 is convenient for binding the safety belt, etc., and can ensure the safety of the maintenance personnel during the climbing or descending process, avoiding the occurrence of potential risks and accidents, and is not limited by the specific working position on the tower body 100. While ensuring the personal safety of the maintenance personnel, it is also convenient for the unbinding or repeated binding of the safety belt and other operational requirements. In addition, the redundant length between the safety belts connected to the connecting seat 3 should not be too long, that is, it should not exceed the distance between the two side frames 11 on the auxiliary ladder 1. On the one hand, it is convenient to observe and adjust the real-time status of the connecting seat 3 and the safety belt connected to it, further improving the connection stability, and on the other hand, it further reduces the descending distance of the maintenance personnel when slipping or falling occurs, ensuring the personal safety of the maintenance personnel while reducing the degree of injury, and the gravity of the connecting seat 3 structure is not enough to affect the normal climbing and descending process of the maintenance personnel, so as to reduce the weight and physical exertion of the maintenance personnel and ensure the stable progress of the operation process.

[0024] like Figure 2 As shown in the figure, an anti-skid pad 321 is provided at the contact position between the holder 32 and the slide bar 2. The anti-skid pad 321 can further increase the friction between the holder 32 and the slide bar 2, thereby reducing the sliding distance of the connecting seat 3 when the holder 32 is in contact with the slide bar 2, that is, the falling distance of the connecting seat 3 when the connecting seat 3 is in a stationary state or when the maintenance personnel slip or even fall in a dangerous situation, further improving the fixing stability of the connecting seat 3 and the protection effect and safety of the maintenance personnel. At the same time, the anti-skid pad 321 can also play a certain shock-absorbing, buffering and protective effect, play a certain protective role on the slide bar 2 and the holder 32, and improve the stability during use.

[0025] See also Figure 4-5 , buffer seats 21 are provided at both ends of the slide bar 2 provided on the frame 11, and the seat body of the buffer seat 21 is slidably provided on the slide bar 2 and is respectively connected with the compression springs 22 sleeved at both ends of the slide bar 2. During the sliding process of the connecting seat 3 on the slide bar 2, it slides to the two ends of the slide bar 2 and contacts with the seat body of its buffer seat 21. The seat body of the buffer seat 21 is subjected to pressure and can play a certain shock-absorbing and buffering effect under the action of the compression springs 22 connected to it at both ends of the slide bar 2, thereby reducing the impact on the frame 11 during the sliding process of the connecting seat 3, further reducing the degree of damage to the connecting seat 3 and the frame 11 and appropriately extending the service life.

[0026] The seat body of the buffer seat 21 is made of any flexible or magnetic material. The seat body can be made of any flexible or magnetic material according to specific usage requirements. The flexible material can play a certain protective role on the connecting seat 3, reducing the impact while reducing the degree of wear between the surface of the connecting seat 3. In addition, the magnetic material is compatible with the material of the connecting seat 3, so that when the connecting seat 3 slides to the two ends of the sliding rod 2 and contacts the buffer seat 21, the buffer seat 21 has a certain adsorption effect on the connecting seat 3, which can avoid the shaking of the connecting rod 31 due to vibration, causing the connecting seat 3 on the sliding rod 2 to become unstable and cause position deviation, thereby further improving the stability and convenience during use.

[0027] Slide bars 2 and connecting seats 3 are provided on the frames 11 on both sides of the auxiliary ladder 1, and multiple groups of slide bars 2 are provided. The connecting seats 3 provided on both sides of the frames 11 can further improve the safety of maintenance personnel in the process of climbing and descending along the tower body 100 on the auxiliary ladder 1 through the connection of safety belts, while ensuring the stable connection of the safety belts and facilitating the binding of the safety belts, and can reduce the movement amplitude and injury degree caused by maintenance personnel when slipping or even falling dangerous situations occur. At the same time, the setting of the multiple groups of slide bars 2 can further improve the supporting stability of the slide bars 2 and the sliding stability of the connecting seats 3, improve the rigidity and stress of the overall structure, make it less likely to be deformed or even damaged, and improve the operation stability and safety.

[0028] The outer side cover of the slide bar 2 on the frame 11 is provided with an adaptive protective cover 4, and a plurality of groups of supports 41 are distributed on the protective cover 4. The supports 41 are adapted to the size of the connecting rod 31 and are slidably arranged on the protective cover 4. The adaptive protective cover 4 provided on the outer side cover of the slide bar 2 on the frame 11 can play a certain protective role on the slide bar 2 and the connecting seat 3 slidably arranged thereon, further reducing the phenomenon that dust and other impurities enter and affect the use effect, and improving the stability during use. In addition, see Figure 6 As shown in the figure, the multiple groups of supports 41 distributed on the protective cover 4 can play a certain supporting role on the connecting rod 31 on the connecting seat 3 by appropriate sliding, thereby preventing the connecting seat 3 from sliding or other positional displacement due to external factors such as vibration in a static state, and the distribution of the supports 41 can be set according to the specific height of the tower body 100 and the height of the auxiliary ladder 1 adapted to it, or the specific position of its maintenance platform to adjust the position of the supports 41 and the connecting seat 3 when the maintenance personnel perform maintenance operations at different maintenance positions, thereby meeting different usage requirements and usage conditions and improving flexibility and convenience during use.

[0029] The auxiliary ladder 1 adopts a split structure, and the frames 11 are respectively hinged to the two ends of the connecting part 14 provided at the connection of the frames 11. Figure 7 As shown, the auxiliary ladder 1 with a split structure can be arranged in multiple sections according to the specific height and shape of the tower body 100, and the adjacent frames 11 are connected by connecting parts 14. At the same time, the two ends of the connecting parts 14 can be rotated and adjusted at corresponding angles, so that the structure of the auxiliary ladder 1 is not affected by the following Figure 7 and Figure 8 The tower body 100 shown in the figure has higher adaptability and fit due to the limitation of its structure, thereby improving the connection stability.

[0030] The frame 11 is also provided with a mounting groove 13, and a plurality of mounting seats 131 for mounting and fixing the frame 11 are slidably provided on the mounting groove 13. Figure 5 As shown in the figure, the mounting groove 13 on the frame 11 and the plurality of mounting seats 131 slidably arranged thereon can facilitate the connection, fixation, installation and disassembly and other operational requirements between the auxiliary ladder 1 and the tower body 100 structure, while ensuring a stable connection and improving the convenience and flexibility of use, and facilitating inspection and maintenance.
