Description

Technical Field

[0001] This utility model relates to the field of pantograph maintenance technology, and in particular to a device for pantograph maintenance. Background Technology

[0002] The pantograph is an electrical device that allows electric traction locomotives to obtain power from the overhead contact line. It is installed on the roof of the locomotive or EMU. There are two types of pantographs: single-arm and double-arm. Both consist of a sliding plate, upper frame, lower arm (double-arm pantographs use a lower frame), base frame, lifting spring, transmission cylinder, and support insulators. During use, the maintenance of the pantograph is particularly important.

[0003] During the maintenance and repair of electric passenger trains, such as replacing airbags or steel cables, the pantograph must be extended before work can be carried out. In current practice, the pantograph is often supported by wood or tied to the contact wire. This is neither aesthetically pleasing nor safe, and neither can guarantee the stability of the pantograph. There is a risk that it may fall and injure employees or damage equipment.

[0004] Therefore, it is necessary to provide a device for pantograph maintenance to solve the above-mentioned technical problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] A device for pantograph maintenance includes a fixing module 1 and an adjustment module 2;

[0027] The adjustment module 2 includes an outer telescopic tube 22, inside which is an inner telescopic tube 21. The inner telescopic tube 21 is threadedly connected to a lead screw 23. The lower end of the lead screw 23 is fixedly connected to the central shaft of a bevel gear 24. The central shaft of the bevel gear 24 passes through and is movably connected to a square frame 27. The square frame 27 is fixedly connected to the outer telescopic tube 22. The bevel gear 24 meshes with a bevel gear 25. The central shaft of the bevel gear 25 passes through and is movably connected to the square frame 27. The end of the central shaft of the bevel gear 25 is fixedly connected to the center of a knob 26.

[0028] The fixing module 1 is provided in two sets. The fixing module 1 includes an upper fixing module and a lower fixing module. The fixing module 1 includes a U-shaped fixing frame 13. Symmetrical protrusions 12 are fixedly connected to one side of the U-shaped fixing frame 13. The two protrusions 12 are respectively connected to the protrusion plate 11 by a pin.

[0029] One side of the U-shaped fixing frame 13 is threadedly connected to a second lead screw 15. One end of the second lead screw 15 is fixedly connected to the center of a second knob 16, and the other end of the second lead screw 15 is movably connected to a top plate 14. One side of the top plate 14 is attached to the inner wall of the U-shaped fixing frame 13.

[0030] The outer surface of the top plate 14 and the inner surface of the U-shaped fixing frame 13 are both provided with rubber layers. The U-shaped fixing frame 13, the outer telescopic tube 22 and the inner telescopic tube 21 are all made of stainless steel.

[0031] The protruding plate 11 of one of the fixed modules 1 is fixedly connected to the inner telescopic tube 21.

[0032] The corresponding protruding plate 11 of the other fixing module 1 is fixedly connected to the square frame 27.

[0033] Working principle: In use, first, the upper frame of the pantograph is positioned between the upper inner wall of the U-shaped fixing frame 13 of the upper fixing module 1 and the top plate 14, and the lower frame of the pantograph is positioned between the upper inner wall of the U-shaped fixing frame 13 of the lower fixing module 1 and the top plate 14. Use an electric wrench to turn knob 16. Knob 16 drives screw 15 to rotate. Screw 15 drives the top plate 14 to move, so that the inner wall of the top plate 14 and the U-shaped fixing frame 13 respectively abut against the upper and lower frames of the pantograph to fix the pantograph. The outer surface of the top plate 14 and the inner surface of the U-shaped fixing frame 13 are both provided with a rubber layer with a thickness of 2mm to protect the paint of the pantograph.

[0034] Then, use an electric wrench to turn knob 26. Knob 26 drives bevel gear 25 to rotate, bevel gear 25 meshes with bevel gear 24 to rotate, bevel gear 24 drives lead screw 23 to rotate, lead screw 23 drives inner telescopic tube 21 to extend or retract along outer telescopic tube 22, causing inner telescopic tube 21 to move the upper fixing module 1 up or down, thereby causing the upper fixing module 1 to pull the pantograph's upper frame up or down. The hinged connection between the convex plate 11 and the convex block 12 allows the convex plate 11 and the convex block 12 to automatically swing when the inner telescopic tube 21 moves the upper fixing module 1, making the fixing effect of the fixing module 1 more stable. After the pantograph is adjusted to the required height for maintenance using this device, stop turning knob 26.

[0035] In summary, this invention solves the problem of fixing different pantographs, enabling pantographs to be inspected and maintained safely, thus protecting the safety of equipment and personnel.

[0036] Beneficial effects: By fixing module 1, the inner walls of top plate 14 and U-shaped fixing frame 13 respectively abut against the upper and lower frames of the pantograph to fix the pantograph. A 2mm thick rubber layer is provided on the outer surface of top plate 14 and the inner surface of U-shaped fixing frame 13 to protect the paint on the pantograph. By adjusting module 2, the upper fixing module 1 pulls the upper frame of the pantograph up or down. The hinged connection between convex plate 11 and convex block 12 allows the convex plate 11 and convex block 12 to automatically swing along with the upper fixing module 1 as the inner telescopic tube 21 moves, making the fixing effect of fixing module 1 more stable and allowing the pantograph to be adjusted to the required height for maintenance. In summary, this utility model solves the problem of fixing different pantographs, enabling safe maintenance of the pantograph and protecting the safety of equipment and personnel.
