Description

A suspension clamp with a heavy hammer suspension point

Technical field:

The invention relates to a suspension clamp with a heavy hammer suspension point, belongs to the field technical field of power transmission line maintenance, and is widely used in the operation of adding a heavy hammer to a pole tower and a corner pole tower on a power transmission line.

Background technique:

During the erection of the transmission line, if the towers on both sides are taller and the middle tower is lower, the taller towers on both sides will generate a pull-up force on the middle tower. When the pull-up force is large, it is easy to make the wire exceed the insulator sheet, and the distance between the wire and the cross-arm is reduced, resulting in insufficient safety distance. In addition, in the corner tower, the larger the angle of rotation, the smaller the distance between the jumper on the outer corner side and the tower. Under extreme conditions such as strong winds, the jumper on the outer corner side is closer to the tower due to the swing, and it is easy to discharge the tower. Installing a heavy hammer at the suspension line clamp of the uplifting pole tower can effectively offset the uplifting force of the pole towers on both sides, so as to keep a sufficient safe distance between the wire and the cross arm. Adding a suspension insulator and installing a weight to the jumper on the outer corner of the corner tower can effectively reduce the swing of the jumper and keep a sufficient safe distance between the jumper and the tower.

After many years of operation of transmission lines, the heavy hammers of some towers have been corroded and need to be replaced, and some lines have changed, and the weight of the heavy hammers needs to be increased or decreased. The traditional way to replace the weight is to combine the power outage plan, open the suspension clamp used to fix the wire, and then replace the weight. The disadvantage of this method is that a hanging wire device needs to be used. During the replacement process, the suspension wire clamp needs to be opened. After the weight is replaced, the suspension wire clamp needs to be installed again. The operation is complicated, the work intensity is high, and the work efficiency is low.

Invention content:

The object of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a suspension line with a heavy hammer suspension point with simple structure, convenient installation, wide application range, simplified on-site operation procedures, reduced on-site operation intensity, and improved work efficiency. folder.

The purpose of the present invention can be achieved through the following measures: a suspension clamp with a heavy hammer suspension point, which includes a hull, is characterized in that there are hanging shafts on both sides of the hull, and two bowl heads stamped from steel plates The lower part of the hanging plate is installed on the hanging shafts on both sides of the hull, and the tail of the hanging shaft is added with a gasket and R pin to prevent it from falling off; the bolts are passed through the screw holes on the upper part of the two bowl-head hanging plates and connected to the bottom of the insulator through the bowl-head hanging plates. Gaskets and R pins are added to the tail to prevent detachment; there are 4 grooves on the upper part of the hull and 2 slots on each side, and two U-bolts pass through the grooves on the upper part of the hull 4 and the slots on both sides to fix the position; There is a pressure plate inside the hull, and the wires are placed inside the hull, pressed by the pressure plate, and fixed with U-shaped bolts; the bottom of the hull is equipped with a weight suspension connecting plate with a through hole, and the weight suspension connecting plate is connected by bolt suspension Heavy hammer device; when it is necessary to replace the heavy hammer, there is no need for power failure on the line, and the working electrician climbs to the live wire through the insulated ladder, and quickly equalizes the potential with the wire; the working electrician will open the heavy hammer suspension connecting plate to fix the heavy hammer device Bolts, after removing the heavy hammer device, pass it to the ground with an insulating rope; the ground electrician binds the new heavy hammer device firmly; the working electrician lifts the new heavy hammer device to the wire, and hangs the new heavy hammer device through the bolt and the heavy hammer The connecting board is connected, and the work is completed, and the working electrician returns to the ground.

Compared with the prior art, the present invention can produce the following positive effects: the present invention can effectively overcome the disadvantages of complex operating procedures, many repetitive actions, and relatively high operating intensity for replacing the weight of the transmission line. which has:

1. Simple structure and easy installation. The invention is a suspension wire clip with a weight suspension point. When installing the heavy hammer, directly hang the heavy hammer device on the connecting plate at the bottom of the hull.

2. Wide application range. The suspension clamp can be applied to most of the uplifting pole towers and corner pole towers of current transmission lines.

3. It can simplify the on-site operation procedure. When the heavy hammer needs to be replaced, there is no need to hang the wire, so the steps of installing and dismounting the wire hanging device are omitted. There is also no need to open the wire clamp, and the bolts connecting the weight device and the weight suspension connecting plate are directly opened to replace the weight.

4. Reduce the intensity of on-site operations and improve work efficiency. Due to the simplification of the hammer replacement operation procedure, the labor intensity of the operators is reduced and the work efficiency is greatly improved. In the past, it took 120 minutes to replace a set of weights, but now it only takes 30 minutes to complete.

The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

Embodiment: a kind of suspension line clamp (referring to Fig. 1-Fig. 3) with heavy hammer suspension point, it comprises hull 4, and both sides of hull 4 are provided with hanging shaft 9, and hanging plate 2 is bowl head hanging plate, is made of Steel plate stamping forms, and two bottoms of bowl head hanging plate 2 are installed on the hanging shaft 9 of hull 4 both sides, and pad and R pin 6 anti-off are added at hanging shaft 9 afterbody. Pass the bolt 1 through the screw holes on the upper part of the two bowl-head hanging plates 2 and connect them to the bottom of the insulator through the bowl-head hanging plate 2, and add gaskets and R pin 6 at the end of the bolt 1 to prevent it from falling off. The upper part of the hull 4 is provided with four grooves 10, and two draw-in grooves 11 are respectively provided on both sides, and two U-shaped bolts 3 are fixed in position through the grooves 10 on the upper part of the hull 4 and the draw-in grooves 11 on both sides. The inside of the hull 4 is provided with a pressing plate 7, and the lead is placed inside the hull 4, pressed down with the pressing plate 7, and fixed with a U-shaped bolt 3. The bottom of the hull 4 is provided with a weight suspension connecting plate 5 with a through hole, and the weight suspension connecting plate 5 is suspended and connected to the weight device by bolts.
