Description

A steel pole for an iron tower of a high-voltage transmission line with a pedal

technical field

The utility model relates to a steel pole used for a high-voltage iron tower erecting an ultra-high-voltage transmission line in the electric power construction field.

Background technique

In the transmission line, the ultra-high voltage transmission line needs to be erected with a high-voltage iron tower. The high-voltage iron tower is generally a square-shaped iron tower composed of four groups of steel rods assembled vertically. Each group of vertical steel rods connected in series The rooms are also connected with channel steel or angle steel to form a truss structure. The two ends of the steel rod are provided with flanges connecting the two steel rods. The side wall of the steel rod is welded with a mounting frame at the position where the truss angle steel is connected. The mounting frame is a channel-shaped steel plate buckled on the wall of the steel rod. Bolt holes are set on the front of the channel steel plate for connecting angle steel and other truss members. When erecting taller and heavier components such as high-voltage iron towers, it is necessary to hoist components such as steel rods to the top of the erected steel rods with a winch tractor. During the hoisting process, it is necessary to set a pole in the air on the top of the four sets of steel poles that have been assembled and erected. A pulley is set on the top of the pole. A pulley for traction. The wire rope for hoisting steel poles and other components passes through the pulley on the upper part of the pole, one end is connected to the steel pole on the ground to be hoisted, and the other end passes through the traction pulleys on the ground in the center of the four sets of iron towers and then connected to the winch tractor , The winch tractor lifts the steel pole and other components to the top of the pole by pulling the wire rope, so as to install and connect to the upper part that has been erected.

Both ends of the steel rods are welded with flanges, and the connection between the two steel rods is mainly to connect the two flanges together through bolts. The steel pole is constantly shaking during the hoisting process. It is not easy to align the flange plate of the hoisted steel pole with the flange plate and bolt holes of the installed steel pole, so the hoisting process The construction personnel need to stand on the upper end of the steel pole that has been installed, and need to manually connect the two steel poles located on the upper and lower sides through the flange, and connect the flange plate and bolt holes at the lower end of the lifted steel pole with the installed steel pole. Align the flanges and bolt holes of good steel rods. However, there are no other parts for construction personnel to stand on the general steel pole except the flange plate connecting the steel pole and the mounting frame connecting the truss angle steel. When construction workers assemble steel poles and their truss components, they can only hang them on the steel poles through safety ropes. At the same time, each steel pole is very thick, and climbing tools such as foot buckles cannot be used. Construction workers have no focus on their feet. The activities of construction personnel are greatly restricted like this, the construction process is very difficult and dangerous, and it is also very inconvenient during loading and unloading, which easily causes construction accidents.

Utility model content

The technical problem to be solved by the utility model is to provide a steel pole for the iron tower of the high-voltage transmission line that is convenient for construction personnel to work.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a steel rod for a high-voltage transmission line iron tower with pedals, including a rod body, flanges arranged at both ends of the rod body, welded on the outer wall of the rod for Install the mounting frame of the steel rod truss. The wall of the rod body is provided with a foot pedal through the mounting frame. .

The further improvement of the specific structure of the utility model is that: the outer side of the pedal opposite to the hook is provided with an upwardly tilted baffle.

The further improvement of the specific structure of the utility model is that: the inner side of the pedal and the hook are provided with bolt holes for piercing bolts matched with the bolt holes on the mounting frame.

The further improvement of the specific structure of the utility model lies in that: the mounting frame on the side wall of the rod body is provided with a reserved frame for optical cables.

Due to the adoption of the above-mentioned technical scheme, the technical progress achieved by the utility model lies in that the steel pole for the high-voltage tower of the utility model is mainly used in the iron tower steel pole for erecting ultra-high voltage transmission lines in the field of electric power construction, and is pre-installed on the steel pole Pedals and other parts, so as to solve the difficult problem of assembling the steel poles of the high-voltage iron tower during the construction and assembly process, and provide a larger working space for the staff. The process is safe and stable, greatly speeding up the construction progress.

The pedal is provided with an upturned baffle to prevent stepping on air or slipping. The foot pedal and the mounting frame of the steel rod are pierced and connected by bolts, which can further increase the safety of the foot pedal suspension. The foot pedal is hooked on the installation frame, and it can be disassembled at any time, which is convenient for use and movement. The optical cable reserve frame set on the installation frame not only provides a reserved installation position for the installation of the optical cable, but also can play the role of foot support.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in the accompanying drawings, a steel pole for an iron tower of a high-voltage transmission line with pedals includes a pole body 30, flanges are arranged at both ends of the pole body, and a mounting frame is provided on the outer wall of the pole body. The mounting frame is normally used for Install the truss angle steel and other components of the iron tower. A pedal 32 is hooked on the mounting frame 4 on the body wall.

As shown in Figures 2 and 3, the cross-section of the pedal 32 of the present utility model is a zigzag, and the pedal 32 is articulated in the installation frame 4 by the hook of the zigzag of the pedal. A baffle plate 36 is arranged on the outer side of the pedal 32 opposite to the hook 35, and the baffle plate 36 is tilted upwards to block the construction personnel's feet, so as to provide the construction personnel with the feeling of the edge of the pedal. The inboard of pedal 32 and hook 35 are provided with the bolt hole that cooperates with the bolt hole on the installation frame 4, after pedal 32 is hung in the installation frame 4, can pass through a bolt 37 again to further fix and prevent pedal Board comes off. An optical cable reserved frame 3 is also arranged on the mounting frame 4 on the side wall of the rod body.

In electric power construction, high-voltage iron towers are generally quadrangular iron towers assembled vertically from four sets of steel rods. When erecting, the winch tractor lifts the steel pole and other components to the top of the pole by pulling the wire rope. During the pulling process, the steel wire rope first lifts one end of the steel pole until the hoist tractor lifts the entire steel pole and other components to The upper part of the steel pole that has been erected, after the hoisting is completed, the construction personnel climb to the joint of the two steel poles, and connect their own safety ropes to the upper flange 2 of the steel pole, and then the two feet of the construction personnel stand separately. On one footboard, complete the bolt connection work between the flanges of the upper steel rod and the lower steel rod. When components in other positions need to be installed, the corresponding positions can be reached by moving the pedals.
