Description

Technical Field

[0001] This utility model discloses a double-line boltless integral dropper, belonging to the field of electrified railway catenary technology. Background Technology

[0002] Subways typically use DC power supply, operate at high density, and have high traction power, requiring the transmission of large amounts of current. Double catenary wires and double contact wires can significantly increase the current-carrying area of ​​the contact network, meeting the high current power supply needs of subway trains and ensuring sufficient electrical energy during starting, acceleration, and climbing.

[0003] The existing urban rail contact network uses a double-line integral dropper device with bolted connection structure for the line clamps. It has many parts, large overall weight, and complex installation. There is a risk of bolts not being tightened properly, and there is also a risk of vibration and loosening during long-term operation. In addition, there is a risk of collision between the pantograph and bolts at small curves due to the track being too high, which increases the workload of installation, operation and maintenance.

[0004] In electrified railway catenary systems, droppers are key components connecting the contact wire and the catenary, and their performance directly affects the stability and current collection quality of the catenary. Traditional dropper structures mostly use bolted connections, which suffer from problems such as complex installation, easy loosening, and high maintenance workload. Furthermore, the fixing method for the return wire is also cumbersome, making it difficult to guarantee its stability and reliability. Therefore, it is necessary to design a new type of boltless integral dropper to solve the problems existing in the current technology. Utility Model Content

[0005] This utility model aims to provide a double-line boltless integral dropper, which achieves the effects of simple installation, reliable connection and convenient maintenance through the coupling design of the wire clamp and the optimized return line fixing method, thereby improving the stability and current collection quality of the contact network system.

[0006] The technical solution of this utility model is as follows: A double-wire boltless integral dropper includes a double-load-bearing wire clamp, a dropper wire, and a double-contact wire clamp.

An upper return line base one is provided at the contact point between the left double-load-bearing cable clamp claw and the left double-load-bearing cable clamp body. An upper return line base one is provided on the upper return line base one for inserting and fixing one end of the upper return line.

An upper return line base two is provided below the upper lifting ring. An upper return line base two is provided on the upper return line base two for inserting and fixing the other end of the upper return line. The dual contact wires pass through two contact wire slots below the dual contact wire clamp. The dual contact wire clamp includes a left dual contact wire clamp and a right dual contact wire clamp. The left and right dual contact wire clamps are coupled together to form a dual contact wire clamp. The left dual contact wire clamp claw above the left dual contact wire clamp and the right dual contact wire clamp claw below the right dual contact wire clamp engage to form a lower lifting ring claw hole. A lower return wire base one is provided at the contact point between the right dual contact wire clamp claw and the right dual contact wire clamp body. A lower return wire base one is provided on the lower return wire base one for inserting and fixing one end of the lower return wire.

A lower return wire base two is provided on the lower return wire base two for inserting and fixing the other end of the lower return wire.

[0007] Preferably, the left double-load-bearing cable clamp includes two arc-shaped buckle slots above it, and the right double-contact wire clamp also has two corresponding arc-shaped buckle slots above it. When the left double-load-bearing cable clamp and the right double-contact wire clamp are coupled, two load-bearing cable buckle slots are formed.

[0008] Preferably, the left double contact wire clamp includes two half-contact wire slots below it, and the right double load-bearing wire clamp also has two corresponding half-contact wire slots below it. When the left double contact wire clamp and the right double load-bearing wire clamp are coupled, two contact wire slots are formed.

[0012] 2. Optimized return line fixing: By setting return line holes on the upper and lower return line bases and fixing the return line by pressing, the fixing of the return line is more secure and reliable, avoiding the loosening problem that may occur in traditional fixing methods, and improving the safety and stability of the contact network system.
