The catenary system is the backbone of railway electrification projects and is a specialized transmission line that runs overhead along the railway line to supply power to electric locomotives. It consists of several components: contact suspension, support devices, positioning devices, supports, and foundations.

[0003] After searching, the utility model with announcement number CN217753523U discloses a contact network additional wire suspension device. However, the installation and disassembly of this suspension device is cumbersome and requires the use of tools. In addition, the operating part is close to the wire, which poses a risk of electric shock. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the existing technology that the installation and disassembly of the suspension device are complicated and require the use of tools, and the operating part is close to the wire, which poses a risk of electric shock. A contact network additional wire suspension device is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A contact network additional conductor suspension device includes a support, a mounting hole is formed on the top of the support, a first cavity is formed inside the support, a second cavity is formed on one side inner wall of the first cavity, a first connecting plate and a second connecting plate are slidably provided inside the first cavity, the first connecting plate and the second connecting plate are parallelly arranged on both sides of the inner wall of the first cavity, a first vertical rod is fixedly connected to the bottom of the first connecting plate, a second vertical rod is fixedly connected to the bottom of the second connecting plate, the bottoms of the first vertical rod and the second vertical rod both extend below the support, and the bottoms of the first vertical rod and the second vertical rod are provided with the same group of clamping components for clamping the conductors;

[0007] A control component for controlling the lifting of the second connecting plate and the first connecting plate is provided inside the first cavity;

[0008] A braking assembly for braking the positions of the first vertical rod and the second vertical rod is provided inside the second cavity.

[0009] In a possible design, the clamping assembly includes two clamping plates, which are arranged parallel to each other in an upper and lower direction, and side plates are fixedly connected on both sides of the clamping plates, rectangular holes are opened inside the side plates, and threaded grooves are opened on one side of the first vertical rod and the second vertical rod, and a threaded hole is opened on the inner wall of one side of one of the rectangular holes, and the internal threads of the threaded hole and the threaded groove are connected with the same fixing screw, and the first vertical rod and the second vertical rod both pass through the rectangular hole, and the first vertical rod is fixedly connected to the clamping plate below, and the second vertical rod is fixedly connected to the clamping plate above.

[0010] In one possible design, a buffer plate is fixedly connected to the inside of the clamping plate, two symmetrically arranged sliding rods are fixedly connected to one side of the buffer plate, a limiting block is fixedly connected to the top of the sliding rod, and the same tension spring is fixedly connected between one side of the limiting block and one side of the clamping plate, and the tension spring is sleeved on the sliding rod.

[0011] In one possible design, the control component includes a rotating shaft rotatably connected to the inner wall of one side of the first cavity, the outer wall of the rotating shaft is fixedly sleeved with a gear, one side of the first connecting plate and the second connecting plate are fixedly connected to a cross plate, and the ends of the two cross plates close to each other are fixedly connected to a first rack, and the first rack is located on both sides of the gear and meshes with the gear.

[0012] In one possible design, the brake assembly includes a second rack slidably connected to the inner wall of one side of the second cavity, the second rack is engaged with the gear, a push rod is slidably passed through one side of the support, and one end of the push rod is fixedly connected to one end of the second rack.

[0013] In a possible design, a plurality of insertion holes are provided on the top of the second rack, an insertion rod is slidably passed through the top of the support, the insertion rod is engaged with the insertion holes, and a pull ring is fixedly connected to the top of the insertion rod.

[0014] In the present application, when in use, the gap between the two clamping plates is used to pass the wire, and the two buffer plates contact the wire. In bad weather, the wire will continuously push the buffer plates to vibrate, and the friction between the slide bar and the clamping plates can reduce the vibration and extend the service life of the device.

[0015] When the device needs to be disassembled, the pull ring can be pulled vertically upwards, and the pull ring drives the insertion rod to move upward, and the insertion rod is removed from the inside of the insertion hole. At this time, the braking state of the second rack is released. Since the weight of the first vertical rod is much greater than the weight of the second vertical rod, the first vertical rod drives the clamping plate below to move downward, and at the same time drives the first connecting plate to move downward, so that there is a gap between the two clamping plates, which makes it easy to remove the device from the side of the wire;

[0016] At the same time, the first connecting plate drives one of the first racks to move downward, the first rack drives the gear to rotate, and then drives the first rack on the other side to move upward, and the first rack drives the second vertical rod to move upward through the connection between the transverse plate and the second connecting plate, and the second vertical rod drives the upper clamping plate to move upward, thereby increasing the gap size and facilitating the removal of the device. At the same time, the second rack moves horizontally, and the second rack drives the push rod to move out;

[0017] During the next installation, the push rod can be pushed, and the push rod drives the second rack to move, which in turn drives the two clamping plates to move closer to each other. After the two clamping plates are close to each other, the wire can be limited. At the same time, the moving position of the second rack can be adjusted according to the size of the wire. After the pull ring and the insertion rod are inserted back, the second rack can be braked again, which is convenient to use.

[0018] Beneficial Effect: Enhanced stability and durability: By designing two buffer plates to resist the conductors and utilizing friction between the slide bar and the clamping plate to reduce vibrations caused by inclement weather, the conductors and the device are effectively protected, extending the overall device lifespan. This design not only improves the device's adaptability to harsh environments but also ensures stable and secure power transmission.

[0019] Simplified installation and removal: The innovative lever and socket detent mechanism makes disassembly of the device extremely simple. Simply pull the pull ring upward to release the brake on the second rack. Gravity and gear transmission then automatically separate the two clamping plates, creating sufficient clearance for easy removal of the device from the conductor side. This process eliminates the need for complex tools, significantly improving installation and removal efficiency.

[0020] Flexible Adaptability to Different Wire Sizes: The device's design allows the second rack to be adjusted based on the actual size of the wire, ensuring the two clamping plates securely and effectively hold the wire. This adjustability not only enhances the device's versatility but also allows for optimal retention in various application scenarios.

[0021] Convenient Operation and User-Friendly User Experience: The push-lever design makes reinstallation or adjustment of the clamping position intuitive and easy. Simply pushing the lever moves the second rack, bringing the two clamping plates closer together and clamping the wire. Combined with the quick-lock feature of the plunger brake system, the entire operation is smooth and fast, significantly enhancing the user experience. BRIEF DESCRIPTION OF THE DRAWINGS
