Description

Technical Field

[0001] This utility model relates to the field of power transmission, specifically to a power transmission and distribution steel pipe pole with lifting points, stepping points, and hanging points. Background Technology

[0002] Transmission and distribution steel pipe poles are formed by hoisting and fixing multiple sections of transmission poles one by one. Generally, the higher the voltage level, the larger and heavier the transmission and distribution steel pipe poles become, which also increases the difficulty of assembling them. For heavier transmission and distribution steel pipe poles, it is impossible to assemble them as a whole on the ground (assemble them as a whole on the ground and then erect them in one go using a crane). Therefore, the transmission and distribution steel pipe poles must be assembled in sections. Typically, the hoisting method using wire slings around the steel pipe pole or using bow-shaped or D-shaped shackles through flange holes, connecting the wire slings and slings, is carried out using a crane. However, due to the lack of a dedicated design for the lifting points of the steel pipe poles, these hoisting and assembly methods have serious risks of wire sling slippage or shackles breaking due to violations of the shackle's force direction when passing through flange holes, easily leading to accidents of falling heavy objects. Therefore, it is necessary to provide a system to prevent unauthorized installation of steel pipe poles (adding lifting points to the inner and outer walls), and to effectively prevent such installations, making the erection of steel pipe poles safer and more controllable.

[0003] In addition to the aforementioned problems, during the fixing of the upper and lower sections of the transmission pole and subsequent maintenance, construction workers need to work at height. Since there are no pre-installed safety belts or fall arrestor attachment points on the existing transmission poles, workers lack effective fall protection when climbing up and down the poles. Furthermore, during the erection of each section of the steel pipe pole, the connection of flanges and accessories requires workers to constantly change positions on the pole. Because there are no attachment points or checkpoints for these position changes, workers often lose protection during these transitions, greatly increasing the risk of falls from height.

[0004] To increase the safety of operators when working at heights, some power transmission poles are welded with foot pedals and hanging points. These foot pedals and hanging points are mainly U-shaped and are made of a single sheet of plate or steel bar bent into shape. The overall strength is not high, and they are easily deformed by pressure during transportation. In addition, the foot pedals and hanging points are set separately, and the foot pedals have a single function. The foot pedal surface is flat, which makes it easy to step into empty space or partially dangle outside during construction, affecting construction safety. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, the purpose of this utility model is to provide a power transmission and distribution steel pipe pole with lifting points, footing points, and hanging points. This solves the problems of the lack of professional lifting points during the hoisting of existing power transmission poles, the separate setting of footing and hanging points, which makes installation more complicated, and the poles are prone to deformation during transportation and unstable footing during construction.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A power transmission and distribution steel pipe pole with lifting points, footholds, and hanging points includes multiple pole sections with flanges at both ends. The pole is characterized by having multiple footholds circumferentially fixedly installed on each section near the flanges, with a gap of less than 5 cm between adjacent footholds. Each foothold includes a connecting plate, a foot pedal, and a reinforcing support. The inner end of the foot pedal is fixedly connected to the connecting plate, and the outer end is inclined upwards. The reinforcing support is located at the lower end of the foot pedal, with both ends fixedly connected to the outer end of the foot pedal and the lower end of the connecting plate, respectively. A safety hook-hanging space is formed between the reinforcing support and the connecting plate. Multiple circumferentially distributed lifting hooks are also fixedly installed on the inner or outer side of the upper end of each pole section. This design ensures that the gap between the footholds is much smaller than the length of an average adult's foot, allowing for free movement during use while ensuring the foot remains firmly on the foothold. The foot pedals are angled upwards at their outer ends, ensuring that when a worker steps on them, their feet remain close to the pole body, preventing them from slipping off the pedals and effectively guaranteeing worker safety. This prevents workers from stepping into empty spaces or having their feet dangling outside the pedals. Reinforcing supports at the lower end of the foot pedals provide support and increase their load-bearing capacity, preventing deformation during transport. These supports also provide a safety hook-up space between themselves and the connecting plate, creating a hook point. This allows workers to attach hooks to the foot pedals on the previous pole section, providing both foot support and a hook point, reducing the need for additional hook points and making installation faster and more convenient. Lifting hooks on each pole section provide sufficient lifting points for easy attachment of lifting equipment to the pole body during hoisting.

[0008] Furthermore, the foot pedal is fixed to the power transmission pole body by welding or by detachable fasteners. This allows for the secure installation of the foot pedal by either welding or fastening it directly to the pole body. Welding provides good stability. Fastener fastening allows the foot pedal to be separated from the pole body before transport, and then reconnected upon arrival at the destination, resulting in a more stable installation structure. Additionally, the number of foot pedals can be increased or decreased as needed.

[0009] Furthermore, each section of the power transmission pole is equipped with multiple screws perpendicular to the pole body, and each foot pedal's connecting plate has four rectangularly distributed through holes. Each through hole on the foot pedal corresponds to a screw, and the foot pedal is secured to the pole body by engaging a locking nut with the screw. This arrangement of multiple through holes on the connecting plate allows the screws to pass through and engage with the locking nut. The four through holes provide four mounting points for each foot pedal, ensuring its stability after installation.

[0010] Furthermore, the outer end of the foot pedal is within the projection plane of the flange. Thus, with the foot pedal inside the flange, it will not be compressed when the power transmission pole is laid down for transport.

[0011] Furthermore, both sides of the connecting plate are bent in the opposite direction to the center of the power transmission pole, forming an arc shape. The connecting plate is integrally formed with the foot pedal or fixed by welding, and the upper end of the connecting plate is bent towards the foot pedal. In this way, the shape of the connecting plate corresponds to the outer end face of the power transmission pole, which can fit well with the power transmission pole, increasing the contact area and friction between the foot pedal and the power transmission pole, making its fixation more stable.

[0012] Furthermore, the outer end of the foot pedal is curved upwards, and anti-slip protrusions or an anti-slip layer are provided on the upper surface of the foot pedal. In this way, the outer end of the foot pedal is curved, which can form a semi-enclosed shape for the foot, providing better protection, while the anti-slip structure can prevent the foot from slipping.

[0013] Furthermore, the lifting buckle is shaped like a "Z" and is installed on the outer end face of the top section of the transmission pole, while the other sections are inside the tube. This allows the bent portion of the lifting buckle to fit snugly against the transmission pole. Additionally, a sealing cap is required on the top section of the transmission pole; therefore, placing the buckle on the outer end face avoids interference with the sealing cap. For the other sections of the transmission pole, the lifting buckle is placed on the inner wall, which is more aesthetically pleasing and prevents interference with other components.

[0022] like Figures 1-5 As shown, the power transmission and distribution steel pipe pole with lifting points, stepping points, and hanging points provided in this embodiment includes multiple sections of power transmission pole body 1 with flanges at both ends. Multiple foot pedals 3 are circumferentially fixedly installed on each section of the power transmission pole body 1 near the flanges. The gap between two adjacent foot pedals 3 is less than 5cm (i.e., two adjacent foot pedals 3 can be tightly fitted together or have a small gap to ensure that the foot does not dangle after movement). Each foot pedal 3 includes a connecting plate 31, a foot pedal 32, and a reinforcing support 33 (the connecting plate 31 and the foot pedal 32 can be formed by integrally bending steel plates, or by welding two plates together). The inner end of the foot pedal 32 is fixedly connected to the connecting plate 31, and the outer end is inclined upwards. The reinforcing support... 33 is located at the lower end of the foot pedal 32, and its two ends are fixedly connected to the outer end of the foot pedal 32 and the lower end of the connecting plate 31, respectively. A safety hook hanging space 34 is formed between the reinforcing support 33 and the connecting plate 31. Multiple lifting buckles 2 are also fixedly installed at the upper end of each section of the transmission pole 1, which are evenly distributed in a circumferential direction. (Specifically, the top of the transmission pole 1 is equipped with a lifting buckle, and the lifting buckles of the other sections of the transmission pole are located at the connecting flange. Except for the top lifting buckle, the protrusion width of the other lifting buckles does not exceed the outer edge of the flange between the transmission pole sections to prevent deformation during transportation. Of course, in actual implementation, the lifting buckles can be installed after transportation. If this method is adopted, the outer edge of the lifting buckle can extend beyond the flange.) In this way, the gap between the foot pedals 3 is much smaller than the length of a typical adult's foot, so that the user can move freely during use and ensure that the foot is always on the foot pedal 3. The foot pedal 32 on foot pedal 3 is inclined upwards at its outer end, so that when the worker steps on foot pedal 3, the foot is always close to the pole body 1 under the guidance of foot pedal 32, and will not move out of foot pedal 32, which can effectively ensure the safety of the worker and prevent the worker from stepping into empty space or having their foot partially hanging outside. The reinforcing support 33 set at the lower end of foot pedal 32 can support foot pedal 32, increase the bearing strength of foot pedal 32, and prevent deformation during transportation. At the same time, the reinforcing support 33 also has a safety hook hanging space 34 between the reinforcing support 33 and the connecting plate 31, forming a hook point. That is, the lower end of foot pedal 3 on the previous section of pole body 1 has a hook point, which can be used by the worker to hook the foot pedal during operation. This means that foot pedal 3 can not only provide foot support, but also provide a hook point, which can reduce the number of hook points and make installation faster and more convenient. The lifting buckles 2 installed on each section of the transmission pole 1 provide sufficient lifting points for easy attachment of the lifting equipment to the transmission pole 1 during lifting.

[0023] During installation, foot pedal 3 can be fixed to the power transmission pole body 1 by welding or by detaching it with fasteners. Welding provides good stability. Fastener fixing allows foot pedal 3 to be separated from the power transmission pole body 1 before transportation, and then reconnected and fixed after arrival at the destination. The fixing structure is also relatively stable. In addition, the number of foot pedals 3 can be increased or decreased according to specific needs.

[0024] Specifically, if fasteners are used to fix the foot pedal 3, multiple screws 4 perpendicular to the pole body 1 need to be provided on each section of the power transmission pole 1. Four rectangularly distributed through holes 35 are provided on the connecting plate 31 of each foot pedal 3. Each through hole 35 on the foot pedal 3 corresponds one-to-one with a screw 4, and is fixed to the power transmission pole 1 after engaging with the screw 4 using a locking nut 5. Thus, multiple through holes 35 on the connecting plate 31 allow the screw 4 to pass through and engage with the locking nut 5. With four through holes 35, each foot pedal 3 has four mounting points, ensuring the stability of the foot pedal 3 after installation.

[0025] In this embodiment, the outer ends of the foot pedals 32 of all foot pedals 3 are within the projection plane of the flange. In actual implementation, if foot pedals 3 are installed on the construction site, the width of the foot pedals 3 can be set wider, extending beyond the flange. In this way, with the foot pedals 32 inside the flange, the foot pedals 3 will not be compressed when the power transmission pole 1 is laid down for transportation.

[0026] Furthermore, both sides of the connecting plate 31 are bent in the opposite direction to the center of the transmission pole body 1, forming an arc shape. The connecting plate 31 is integrally formed with the foot pedal 32 or fixed by welding, and the upper end of the connecting plate 31 is bent towards the foot pedal 32. In this way, the shape of the connecting plate 31 corresponds to the outer end face of the transmission pole body 1, which can fit well with the transmission pole body 1, increasing the contact area and friction between the foot pedal 3 and the transmission pole body 1, making its fixation more stable.

[0027] Furthermore, the outer end of the foot pedal 32 is curved upwards, and anti-slip protrusions or an anti-slip layer are provided on the upper surface of the foot pedal 32. In this way, the outer end of the foot pedal 32 is curved, which can form a semi-enclosed shape for the foot, providing better protection, while the anti-slip structure can prevent the foot from slipping.

[0028] like Figure 6 As shown, the lifting buckle 2 is shaped like a "Z" and is installed on the outer end face of the top section of the transmission pole 1, inside the tubes of the other sections of the transmission pole 1. This allows the bent portion of the lifting buckle 2 to fit snugly against the transmission pole 1. Furthermore, a sealing cap is required on the top section of the transmission pole 1; therefore, placing the buckle on the outer end face avoids interference with the sealing cap. For the other sections of the transmission pole 1, the lifting buckle 2 is placed on the inner wall, which is more aesthetically pleasing and prevents interference with other components.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
