Background technique

The crossarm is an important part of the tower. Its function is to install insulators and fittings to support the wires and lightning conductors and keep them at a certain safe distance according to regulations. The angle iron fixed horizontally on the top of the utility pole has a porcelain vase on it, which is used to support the overhead wire.

In the overhead power transmission operation of poles and elevated iron towers, it is necessary to use a cross-arm seat with hoops. The hoops are used to fix on poles or other supports, and the cross-arms are used to install other components.

With the widespread use of ultra-high-voltage and high-power transmission lines, the size, weight, and number of installations of insulating equipment and fittings that need to be used are increasing. A large amount of deposits are deposited on the high-altitude parts, resulting in increased weight. The hoop cross-arm of the existing equipment is spot-welded, and the connection method is not firm enough, so it is difficult to work for a long time under heavy load. Once it breaks, it will cause an electrical accident and cause huge losses.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in further detail.

The adjustable hoop welding tool described in the utility model includes two semicircular hoops and clamping bolts 5, the two free ends of the semicircular hoops are respectively connected with a splint 1, and the splints are There is a clamping bolt hole 3, and there is a welding platform 6 at the midpoint of the arc of the semicircular hoop, and a cross-arm fixing plate 2 extending in a direction parallel to the extending direction of the splint is welded on the welding platform, and the cross-arm There are a plurality of cross-arm bolt holes 4 on the fixed plate.

As shown in Figure 1, the welding platform 6 is located on the side away from the center of the arc at the midpoint of the semicircular hoop. The outer side of the original semicircular hoop is in the shape of an arc. The welding area of the fixed plate is limited, although it can be reinforced by adding solder to fill the gap between the arc and the fixed plate of the cross arm, the welding strength obtained in this way is not stable, and the operating strength is also improved. A welding platform is added to the original welding point on the outside of the semicircular hoop. The welding platform is a flat surface with a certain area that is integrally cast with the semicircular hoop. By increasing the welding area, the cross arm is effectively strengthened. The welding strength of the fixed plate and the hoop. The width of the welding platform 6 is generally consistent with the width of the semicircular hoop, and the length can be set between 10-40 mm. If the length is too short, the welding strength is not enough, and if the length is too long, the processing cost and cost of the semicircular hoop will be increased. The weight is not conducive to the installation and carrying of high-altitude power transmission.

Generally speaking, the opening of the hoop should not be larger than the diameter of the pole, otherwise it will be difficult to clamp, it is best to be equal, and the central angle of the hoop is 180 degrees, and the clamping effect is the best at this time. However, in practical applications, the diameter of the pole is often different, so the central angle of the circular hoop is preferably set at 120-150 degrees, which can adapt to a relatively wide range of pole diameters.

There are more than one clamping bolt holes 3 on each splint, which are arranged in sequence along the extending direction of the splint. Using multiple clamping bolt holes arranged along the extension direction of the splint, on the one hand, multiple clamping bolts can be used to clamp at the same time, which increases the clamping strength. At the same time, in the case of only one pair of clamping bolts, the The different diameters of the clamping poles lead to different clamping joints. Choose different positions to install the clamping bolts to achieve a better clamping effect. For example, when the diameter of the pole is large, the distance between the clamping bolt holes close to the pole If it is stretched, the clamping bolts are easy to fall off after installation. At this time, you can choose the clamping bolt holes far away from the pole to install the clamping bolts.

In order to further enhance the clamping strength, the utility model can set the internal thread of the cross arm bolt hole and the clamping bolt hole to be able to cooperate with the clamping bolt, and each clamping bolt hole has a cross arm bolt corresponding to its position Holes, so that the clamping bolts can pass through the clamping bolt holes of the two semicircular drums and the corresponding cross-arm bolt holes in sequence. The clamping bolts are continuously passed through the clamping bolt holes and the cross-arm bolt holes. The clamping bolts simultaneously clamp the two hoops and fix the two cross-arm fixing plates, which further strengthens the connection between the cross-arm fixing plate and the cross-arm fixing plate. The firmness of the connection of the hoop.

The adjustable hoop welding tool described in the utility model adopts the method of adding a welding platform at the midpoint of the hoop arc, and by increasing the welding area, the welding strength between the cross-arm fixing plate and the hoop is effectively enhanced. Preferably, the clamping bolts are continuously passed through the clamping bolt holes and the cross-arm bolt holes to further increase the connection strength between the hoop and the cross-arm fixing plate, so that the utility model is suitable for various cross-arm heavy loads The construction of ultra-high voltage and high-power transmission line network.
