Description

Technical Field

[0001] This utility model relates to the field of railway engineering technology, and in particular to a gantry support frame for traction power supply. Background Technology

[0002] In the field of railway engineering, the traction power supply gantry support frame is a key supporting equipment in railway locomotive depots, shunting yards, and other areas, mainly used in traction operations near railway line level crossings. When locomotives need to move short distances between the depot's unpowered area and the work line, or complete traction actions such as entering and exiting the depot shed or train marshalling, they need to obtain power from the sliding contact line of the track bridge erected by the traction power supply gantry support frame to ensure the stable operation of traction work.

[0003] However, when the level crossing span is large, such as 10 to 16 meters wide, existing gantry support frames for locomotive power supply have limitations in adaptability and are difficult to install and use normally. In particular, the lightweight design of the track bridge conductor rail is prone to excessive deflection in large-span support scenarios, leading to conductor rail deformation and seriously affecting the smooth passage of locomotives during towing operations. If this problem is solved by modifying the conductor rail design itself, the relevant materials need to be reselected and redesigned, which not only results in a long development cycle but also significantly increases investment costs, making it difficult to meet the actual needs of power supply for towing in large-span level crossings.

[0004] Therefore, there is an urgent need to propose a gantry support frame for traction power supply to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a gantry support frame for locomotive power supply, which greatly improves the overall stability and anti-deformation ability of the support, thereby avoiding the deformation problem of the sliding contact line of the track bridge when the span of the level crossing is large, and ensuring the stable operation of locomotive traction.

[0006] To achieve this objective, the present invention adopts the following technical solution:

The support frame is connected between the tops of the two first columns to be erected on the top of the level crossing.

[0009] The second support assembly comprises two sets, which are respectively located on opposite sides of the first support assembly along the track extension direction. Each second support assembly includes a second column and a counterweight connecting beam. The second column is located on the ground and spaced apart from the first column. The counterweight connecting beam connects the top of the second column and the top of the first column. The central axis of the counterweight connecting beam is collinear with the central axis of the support frame and is both located along the track extension direction. The track bridge sliding contact line is suspended and connected to the support frame and the counterweight connecting beam. The length direction of the track bridge sliding contact line is consistent with the track extension direction.

[0010] In some embodiments, the first support assembly further includes a first connecting beam, one end of which is connected to the support frame or the first column, the other end of which extends horizontally outward, and the first connecting beam is perpendicular to the support frame. The track bridge sliding contact line is connected to the bottom of the other end of the first connecting beam.

[0011] In some embodiments, the second support assembly further includes a second connecting beam, one end of which is connected to the second column or the counterweight connecting beam, and the other end of which extends horizontally outward. The second connecting beam is perpendicular to the counterweight connecting beam, and the track bridge sliding contact line is connected to the bottom of the other end of the second connecting beam.

[0012] In some embodiments, multiple first connecting beams are spaced apart along the extension direction of the support frame, and multiple second connecting beams are spaced apart along the extension direction of the counterweight connecting beam. Each first connecting beam and each second connecting beam is connected to the sliding contact line of the track bridge.

[0013] In some embodiments, the track bridge sliding contact line is welded to the first connecting crossbeam; and / or

[0018] In some embodiments, the support frame is detachably connected to the first column, and the counterweight connecting beam is detachably connected to both the first column and the second column.

[0019] In some embodiments, the support frame includes a first section and a second section, which can be joined together by threaded fasteners.

[0020] In some embodiments, the number of the gantry support frames for traction power supply is set in a one-to-one correspondence with the number of level crossings.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] like Figures 1-3 As shown, this embodiment provides a gantry support frame for traction power supply, used to erect the rail bridge sliding contact line 10. The locomotive obtains power through electrical connection with the rail bridge sliding contact line 10, thereby ensuring the stable operation of traction work. The working principle of the locomotive achieving traction work through the rail bridge sliding contact line 10 is a mature existing technology in this field and will not be described in detail here.

[0039] The gantry support frame for the traction power supply includes a first support component 1 and a second support component 2.

[0040] The first support component 1 includes two first columns 11 and a support frame 12. The two first columns 11 are respectively set on the ground outside both ends of the level crossing 20 along the track extension direction (X direction in the figure). The support frame 12 is connected between the tops of the two first columns 11 to be erected on the top of the level crossing 20.

[0041] Two sets of second support components 2 are provided, respectively located on opposite sides of the first support component 1 along the track extension direction. Each second support component 2 includes a second column 21 and a counterweight connecting beam 22. The second column 21 is set on the ground and spaced apart from the first column 11. The counterweight connecting beam 22 connects the top of the second column 21 and the top of the first column 11. The central axis of the counterweight connecting beam 22 is collinear with the central axis of the support frame 12 and is set along the track extension direction. The track bridge sliding contact line 10 is suspended and connected to the support frame 12 and the counterweight connecting beam 22. The length direction of the track bridge sliding contact line 10 is consistent with the track extension direction.

[0042] The direction of track extension is the X direction in the figure, which is also the width direction of level crossing 20.

[0043] The gantry support frame for traction power supply provided in this embodiment, by adding second support components 2 on both sides of the first support component 1, can distribute the load-bearing force of the gantry support frame to the first column 11 and the second column 21. That is, the gantry support frame for traction power supply is upgraded to a distributed force structure of "main support + double-sided auxiliary support", which greatly improves the overall stability and deformation resistance of the support, thereby avoiding the deformation problem of the track bridge sliding contact line 10 when the span of the level crossing 20 is large, and ensuring the stable operation of locomotive traction.

[0044] Optionally, the first column 11 and the second column 21 can be standard columns with foundations on the ground, or non-standard columns with foundations on the ground; no specific limitation is made here.

[0045] like Figure 2 As shown, in some embodiments, the first support component 1 further includes a first connecting beam 13, one end of which is connected to the support frame 12, and the other end of which extends horizontally outward. The first connecting beam 13 is perpendicular to the support frame 12, and the track bridge sliding contact line 10 is connected to the bottom of the other end of the first connecting beam 13.

[0046] With this setup, the first connecting beam 13 can precisely extend the rail bridge sliding contact line 10 to the preset working position above the level crossing 20, so that the rail bridge sliding contact line 10 and the locomotive power receiving structure are precisely aligned.

[0047] In some other possible embodiments, one end of the first connecting beam 13 may also be perpendicularly connected to the first column 11.

[0048] like Figure 2 As shown, in some embodiments, the second support assembly 2 further includes a second connecting beam 23. One end of the second connecting beam 23 is connected to the second column 21, and the other end of the second connecting beam 23 extends horizontally outward. The second connecting beam 23 is perpendicular to the counterweight connecting beam 22, and the track bridge sliding contact line 10 is connected to the bottom of the other end of the second connecting beam 23. With this configuration, the second connecting beam 23 can precisely suspend the track bridge sliding contact line 10 to a preset working position above the level crossing 20. At the same time, it cooperates with the first connecting beam 13 to form a multi-point coordinated suspension support, further dispersing the load on the track bridge sliding contact line 10 and reducing the risk of deflection deformation of the track bridge sliding contact line 10.

[0049] In some other possible embodiments, one end of the second connecting beam 23 may also be perpendicularly connected to the counterweight connecting beam 22.

[0050] like Figure 2As shown, in some embodiments, multiple first connecting beams 13 are spaced apart along the extension direction of the support frame 12, and multiple second connecting beams 23 are spaced apart along the extension direction of the counterweight connecting beam 22. Each first connecting beam 13 and each second connecting beam 23 is connected to the track bridge sliding contact line 10.

[0051] With this setup, multiple first connecting beams 13 and multiple second connecting beams 23 are spaced out and synchronously connected to the rail bridge sliding contact line 10, forming multi-point spaced support, which helps to further improve the installation stability and deformation resistance of the rail bridge sliding contact line 10.

[0052] Optionally, the track bridge sliding contact line 10 is welded to the first connecting crossbeam 13. The welded connection has high strength and stability.

[0053] Alternatively, the track bridge sliding contact line 10 is welded to the second connecting crossbeam 23.

[0054] In some embodiments, the first connecting beam 13 is detachably connected to the support frame 12, or the first connecting beam 13 is detachably connected to the first column 11.

[0055] This design allows for easy disassembly and maintenance of the first connecting beam 13 via a detachable connection, while also reducing transportation difficulties. The detachable connection method includes, but is not limited to, fixing with clamp bolts.

[0056] Similarly, the second connecting beam 23 and the second column 21, or the second connecting beam 23 and the counterweight connecting beam 22, can be detachably connected. The detachable connection can be, but is not limited to, using clamp bolts for fixing.

[0057] like Figure 2 and Figure 3 As shown, in some embodiments, two rail bridge sliding contact lines 10 are provided, and the two rail bridge sliding contact lines 10 are symmetrically arranged on opposite sides of the support frame 12.

[0058] With this setup, the two rail bridge sliding contact lines 10 on a single gantry support frame can supply power to locomotives on two parallel railway lines, which greatly improves the utilization efficiency of the equipment.

[0059] like Figure 2 As shown, in this embodiment, when there are two sliding contact lines 10 of the track bridge, the first connecting beam 13 and the second connecting beam 23 at each connection point are respectively set as two lines extending in opposite directions.

[0060] In some embodiments, the support frame 12 is detachably connected to the first column 11, and the counterweight connecting beam 22 is detachably connected to both the first column 11 and the second column 21. This arrangement facilitates the disassembly and transportation of the components, helping to reduce the difficulty of transporting the overall structure. The detachable connection methods include, but are not limited to, fixing with clamp bolts.

[0061] Furthermore, in some embodiments, the support frame 12 includes a first portion and a second portion, which can be joined together by threaded fasteners.

[0062] When the span of the level crossing 20 is large, the corresponding support frame 12 is also large. Therefore, by splitting the support frame 12 into a first part and a second part that can be assembled, the difficulty of transportation, hoisting and other tasks can be further reduced.

[0063] In practical applications, a railway line may have multiple level crossings 20. In this case, the number of traction power supply gantry support frames is set one-to-one with the number of level crossings 20, so that each level crossing 20 is equipped with at least one set of traction power supply gantry support frames.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
