Description

Technical Field

[0001] This utility model relates to the field of railway construction equipment technology, and more specifically, to a railway catenary construction positioning trolley. Background Technology

[0002] The railway overhead contact system is a special power supply device erected above the railway to transmit electrical energy to electric locomotives or EMU trains. It consists of overhead conductors, supporting structures, and insulation equipment. Through close contact between the pantograph and the power receiving device on the top of the train, it continuously transmits high-voltage electrical energy to the train traction system, essentially acting as a "mobile power transmission channel." It is a core infrastructure for achieving efficient traction in electrified railways.

[0003] In railway overhead contact line construction, positioning pulleys are crucial tools for supporting and laying cables. However, traditional positioning pulleys often suffer from poor versatility and insufficient installation stability. On the one hand, their pulley spacing is fixed, making it difficult to adapt to cables or wires of different diameters and lacking flexibility in different construction environments. On the other hand, their suspension structure is mostly fixed, making it difficult to maintain effective balance when the pulley's center of gravity shifts due to carrying different cables, posing a risk of tipping over and affecting construction safety and efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example

[0016] Please see Figures 1-3 A railway catenary construction positioning trolley, comprising: A trolley main frame 1, with a rotating shaft 2 rotatably connected between the inner walls of its two sides; a fixed wheel plate 3 is fixedly sleeved on the rotating shaft 2, and a movable wheel plate 4 is slidably sleeved on the rotating shaft 2; and Side connection box 5 is fixedly connected to one outer surface of the trolley main frame 1. An adjusting threaded rod 9 is rotatably connected between the side connection box 5 and the trolley main frame 1. Two transmission rods 7 are fixedly connected to one outer surface of the movable wheel plate 4. Both transmission rods 7 slide through one inner wall of the trolley main frame 1. One end of the two transmission rods 7 is fixedly connected to a butterfly transmission plate 8. The butterfly transmission plate 8 is threadedly connected to the adjusting threaded rod 9.

[0017] In a specific embodiment of this utility model, the rotating shaft 2, the fixed wheel plate 3, and the movable wheel plate 4 form an adjustable pulley component. The space between the fixed wheel plate 3 and the movable wheel plate 4 is used to place cables or cords. By controlling the rotation of the adjusting threaded rod 9, the butterfly transmission plate 8 is moved, so that the butterfly transmission plate 8 drives the movable wheel plate 4 to slide on the rotating shaft 2 through two transmission rods 7, thereby adjusting the distance between the movable wheel plate 4 and the fixed wheel plate 3, thus adapting to the placement of cables or cords of different specifications and meeting the installation and positioning requirements in different environments.

[0018] Specifically, a round handle 10 is rotatably connected to one outer surface of the side-connecting box 5, and the round handle 10 is fixedly connected to the adjusting threaded rod 9.

[0019] In this embodiment, the threaded rod 9 can be adjusted more conveniently by rotating the round handle 10.

[0020] Specifically, a limiting rod 11 is fixedly connected between the side box 5 and the main frame 1 of the trolley, and the butterfly transmission plate 8 is slidably sleeved on the limiting rod 11.

[0021] In this embodiment, the limiting rod 11 keeps the butterfly-shaped transmission plate 8 stable during movement.

[0022] Specifically, a circular hole is provided in the central area of ​​the butterfly-shaped transmission plate 8.

[0023] In this embodiment, the diameter of the circular hole is larger than the diameter of the end of the rotating shaft 2, so that the movement of the butterfly transmission plate 8 will not be interfered with by the end of the rotating shaft 2.

[0024] Specifically, a movable hook 6 slides through the top of the trolley main frame 1, and a transmission block 12 is fixedly connected to the bottom of the movable hook 6. A transmission threaded rod 13 is rotatably connected to one side of the outer surface of the transmission block 12, and the transmission threaded rod 13 is threadedly connected to one side of the inner wall of the trolley main frame 1.

[0025] In this embodiment, the movable hook 6 is used to suspend on the already installed wrist arm or positioning tube. By rotating the transmission threaded rod 13, the transmission block 12 is moved, thereby adjusting the position of the movable hook 6 so that the movable hook 6 is adapted to the adjusted rotating shaft rod 2, fixed wheel plate 3 and movable wheel plate 4, ensuring the stability of the center of gravity, thereby ensuring the overall structure of the device is stable and reliable when suspended on the wrist arm or positioning tube.

[0026] Specifically, two round rods 14 are fixedly connected to one side of the outer surface of the transmission block 12, and both round rods 14 slide through one side of the inner wall of the trolley main frame 1.

[0027] In this embodiment, the two round rods 14 prevent the transmission block 12 from rotating with the transmission threaded rod 13, thus ensuring the stable movement of the movable hook 6.

[0028] Working principle: The fixed wheel plate 3 and the movable wheel plate 4 are used to place cables or cords. By rotating the round handle 10, the adjusting threaded rod 9 is rotated, which drives the butterfly transmission plate 8 to move. The butterfly transmission plate 8 drives the movable wheel plate 4 to slide on the rotating shaft 2 through the two transmission rods 7, thereby adjusting the distance between the movable wheel plate 4 and the fixed wheel plate 3. This adapts to the placement of cables or cords of different specifications and meets the installation and positioning requirements in different environments. The movable hook 6 is used to suspend the device on the already installed bracket or positioning tube. By rotating the transmission threaded rod 13, the transmission block 12 is moved, thereby adjusting the position of the movable hook 6 so that it matches the adjusted rotating shaft 2, fixed wheel plate 3 and movable wheel plate 4, ensuring the stability of the center of gravity. This ensures that the overall structure of the device is stable and reliable when suspended on the bracket or positioning tube.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
