The line-lifting device has the characteristics of simple and reliable structure, labor-saving and time-saving properties and convenient construction.

Description

Hanger for power line spanning construction

technical field

The utility model relates to a wire-suspending appliance, in particular to an appliance used to protect the underspan objects during power line construction and hoist the hanging wire or the ground wire.

Background technique

In the maintenance work of transmission lines, the work of replacing and removing the ground wires is often encountered. How to deal with and protect the lower crossings in the work is often a core issue. With the development of society and economy, crossings are encountered in power line construction There are more and more types, such as: crossing highways, railways, power lines, etc. In previous constructions, the following processing methods were often used: 1. Loosening method: loosen the underspan line to the ground before the main body construction, and restore the underspan line after the main body construction is completed. This method is safe and reliable, but the construction is complicated, time-consuming and costly; 2. Spanning method: set up a spanning frame at the lower span point, and the spanning frame is divided into unilateral spanning frame and closed spanning frame (closed spanning frame is multi-purpose For live across the construction). This method has high safety, but due to the influence of the terrain and the height of the underspan line to the ground, etc., it has great limitations, complicated construction, time-consuming and expensive construction.

Utility model content

The purpose of the utility model is to provide a labor-saving, time-saving and convenient construction of a power line spanning wire hanger.

The purpose of this new model is achieved in the following way: a power line spans a wire hanger for construction, a cross bar is fixedly connected near the sealing end of the U-shaped lifting ring to form a hanging ring hole for tying the rope, and the hole near the opening end of the U-shaped lifting ring A bolt is worn and hung, and a bearing is arranged at a position inside the open end of the U-shaped suspension ring on the bolt.

Cotter pins are arranged at the outer ends of the screw rods of the above-mentioned bolts.

The specific method of use of this new type:

The construction personnel boarded the towers on both sides of the crossed point, installed the suspension rings on the towers one by one on the guide (ground) wires to be replaced, and tied the traction rope to the hanging rings of the suspension rings. The construction personnel below pull the traction rope to pull the suspension rings below the crossing point. During the construction process, the position and number of suspension rings can be adjusted according to actual needs. When the wire is loosened, the loose guide (ground) wire is placed on the unloose guide (ground) wire through the rope and the lifting ring, after ensuring the distance to the spanning object, the span below is basically not affected by the construction. After the construction is finished, pull back the traction rope and remove the lifting ring.

Compared with the prior art, the beneficial effects of the present invention are:

1. The structure of this new type is simple and reliable, and the on-site construction is convenient, and the safety of the crossing below is not affected by the construction.

2. Labor-saving, time-saving and cost-saving

Compared with the loosening method, there is no need to loosen the lower span line to the ground. This new type has the advantages of labor saving, time saving and cost saving; , labor saving, time saving and cost saving advantages.

Description of drawings

Fig. 1 is a structural diagram of the present invention;

Fig. 2 is the schematic diagram when using the new model to carry out construction (claiming ring method construction).

Detailed ways

Figure 1 shows that a cross bar 2 is fixedly connected to the vicinity of the sealing end of the U-shaped suspension ring 1 to form a hanging ring hole for tying the rope, and a bolt 3 is hung in the hole adjacent to the open end of the U-shaped suspension ring, and the U-shaped suspension ring is mounted on the bolt 3. A bearing 4 is arranged at the position inside the open end. Bolt is made up of screw rod and nut. A cotter pin is arranged at the outer end of the screw rod of the bolt 3 . The cotter pin is inserted in the hole of the screw rod.

The U-shaped lifting ring is made of Q235 carbon steel, and the opening is sealed with bolts, and a cotter pin is used to prevent the bolts from withdrawing. The upper cross bar forms a hanging ring for fastening the ring rope.

Figure 2 shows that the method of hanging the wire (the wire hanging the ground wire, the ground wire hanging wire, and the wire hanging wire) is adopted at the crossing point with the ring and the rope, so that the ground wire is far away from the line under the span, so as to protect the lower span. The role of cross-things. This method is simple, highly feasible and less time-consuming.

Claims (2)

1. A wire hanger for power line spanning construction is characterized in that: a cross bar (2) is fixedly connected to the vicinity of the sealing end of the U-shaped suspension ring (1) to form a hanging ring hole for tying the rope, and the vicinity of the open end of the U-shaped suspension ring A bolt (3) is hung in the hole of the bolt (3), and a bearing (4) is arranged at the position within the open end of the U-shaped suspension ring on the bolt (3). 2. The wire hanger for power line crossing construction according to claim 1, characterized in that: the outer end of the screw rod of the bolt (3) is provided with a cotter pin.
