[0001] The utility model relates to the technical field of overhead rigid catenary, in particular to a suspension assembly for a conductive rail. Background Art

[0002] The overhead rigid catenary technology is an important part of the traction power supply system of rail transit, and is widely used in subways, railways and other fields. During the erection of the overhead rigid catenary, multiple wire clips are mainly used to clamp and fix the conductive rail, and the suspension assembly is used to hang the wire clips at intervals on the suspension base. During use, due to the thermal expansion and contraction of the conductive rail itself and the force exerted by the pantograph during the operation of the locomotive, the conductive rail and the wire clip may become stuck, posing a great potential hazard. Therefore, regular inspections and maintenance are required to ensure the stable operation of the catenary and the safety of train operation.

[0003] At present, the inspection method for whether the conductive rail and the wire clip are stuck mainly relies on manual inspection. On the premise of power-off and ensuring safety, gently push and pull the conductive rail or the wire clip to observe whether there is any stuck or increased resistance. This operation requires professional technicians to avoid unnecessary damage to the equipment, and the workload is large. It is easy to make mistakes relying on the subjective judgment of the inspector. In addition, when conditions permit, equipment such as a vibration tester can be used to perform vibration tests on the conductive rail to evaluate whether there are potential stuck problems, which is cumbersome and time-consuming.

[0015] Furthermore, the bottom end of the lower connecting rod has an inverted T-shaped shaft head structure, the bottom end of the lower connecting rod is adapted to a second inverted T-shaped shaft hole on the wire clamp, so as to suspend the wire clamp on the component main body, and the lower connecting rod can rotate around its own axis after suspension.

Detailed Description of the Preferred Embodiments

[0028] The following further describes the detailed embodiments of the present utility model with reference to the drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not limit the present utility model.

[0029] Embodiment 1

[0030] Figure 1-8 Shows a suspension assembly for a conductive rail of the present utility model. As Figure 1-7As shown in the figure, the hanging assembly for the conductive rail includes an assembly main body 1, a connecting member 2, and a wire clamp 3. An upper connecting rod 11 is provided at the top of the assembly main body 1, and the top end of the upper connecting rod 11 is rotatably provided on the connecting member 2. The connecting member 2 is fixedly connected to the hanging base 4; a lower connecting rod 12 is provided at the bottom of the assembly main body 1, and the wire clamp 3 is rotatably provided at the bottom end of the lower connecting rod 12. The wire clamp 3 is used to set the conductive rail 5.

[0031] The connecting member 2 is the core component for realizing the rotational connection between the assembly main body 1 and the hanging base 4. Its structure can be in various forms as long as the rotational connection can be achieved. Here is a feasible structure. As Figure 3 shown in the figure, the connecting member 2 includes an upper connecting plate 21, a lower connecting plate 22, a fastening bolt assembly 23, a rotary joint 24, and a rotary fastener 25. The fastening bolt assembly 23 is used to clamp and fix the upper connecting plate 21 and the lower connecting plate 22 on the hanging base 4; through holes for the upper connecting rod 11 to pass through are provided on both the upper connecting plate 21 and the lower connecting plate 22; the rotary joint 24 is rotatably provided on the upper connecting plate 21 and can be fixedly connected to the upper connecting rod 11 through the rotary fastener 25.

[0032] As Figure 2 shown in the figure, usually the hanging base 4 is a trough-shaped structure, and mounting hole groups are spacedly opened on the trough bottom surface for mounting the hanging assembly. Both the upper connecting plate 21 and the lower connecting plate 22 are strip-shaped plate structures. As Figure 1 shown in the figure, they are respectively placed in a fitting manner on the upper and lower surfaces of the trough bottom of the hanging base 4, and then fixed by bolt fastening.

[0033] As Figure 3 shown in the figure, there are two fastening bolt assemblies 23, and the fixation is more firm. Each fastening bolt assembly 23 includes a bolt with a cap 231, a fastening nut 232, and a gasket 233. Through holes for the bolt with a cap 231 to pass through are provided on both the upper connecting plate 21 and the lower connecting plate 22; a counterbore for accommodating the bolt with a cap 231 is also provided on the lower connecting plate 22. During installation, the bolt with a cap 231 passes through the lower connecting plate 22, the trough bottom plate of the hanging base 4, and the upper connecting plate 21 from bottom to top in sequence. Then, the gasket 233 is placed on the top end, and the fastening nut 232 is tightened to fix the connecting member 2 on the hanging base 4. The counterbore hides the nut of the bolt with a cap 231, which can provide more space for the axial height adjustment of the assembly main body 1.

[0034] The cross-section of the upper connecting plate 21 is in a convex shape; there is enough space in the convex part to arrange the rotary joint 24. The through hole for the upper connecting rod 11 to pass through on the upper connecting plate 21 is provided in the convex part of the plate body, and the through holes for the bolt with a cap 231 to pass through are provided on both sides of the convex part of the plate body. The through hole and the through holes are perpendicular to the plate surface of the upper connecting plate 21, and their axes are along the vertical direction during installation.

[0035] The rotary joint 24 has a sleeve structure in an inverted T shape. The rotary joint 24 is embedded in the first inverted T-shaped shaft hole on the upper connecting plate 21 and can rotate around its own axis. Through the mutually adapted inverted T-shaped sleeve structure and the first inverted T-shaped shaft hole, a rotational connection is achieved, and then as a rotational connection transition part between the upper connecting rod 11 and the connecting part 2, the structural design is ingenious.

[0036] The inner hole of the rotary joint 24 and the rotary fastener 25 are both threadedly connected to the upper connecting rod 11 respectively. The upper connecting rod 11 is provided with external threads and is threadedly connected to the rotary joint 24, and then the top tightening and fixing are realized through the rotary fastener 25. Specifically, the rotary fastener 25 can be a locknut, which is tightened from the top end of the upper connecting rod 11 and tightened against the rotary joint 24. During actual use, by adjusting the position of the rotary fastener 25 on the upper connecting rod 11 up and down, the axial height of the component main body 1 can be adjusted, making the installation more convenient. Generally, the adjustable range is 0 - 15 mm.

[0037] In addition, the top surface of the rotary joint 24 needs to be higher than the plate surface of the upper connecting plate 21 to abut against the rotary fastener 25. As Figure 3 and Figure 8 shown, the rotary joint 24 has a sleeve structure in an inverted T shape, and an external hexagonal structure is provided on the outer side of the top end higher than the plate surface of the connecting plate 21, which is convenient for manual control. The first inverted T-shaped shaft hole on the upper connecting plate 21 is arranged at the top end of the through hole for the upper connecting rod 11 to pass through.

[0038] The upper connecting plate 21 is a split structure, and after docking and splicing, a first inverted T-shaped shaft hole is formed. Specifically, it can be evenly divided into two parts, and the two parts are symmetrical. As Figure 3 shown, the two parts are respectively fixed by a fastening bolt assembly 23 and then completed docking and splicing to form a complete first inverted T-shaped shaft hole. The rotary joint 24 is placed before docking and splicing.

[0039] In order to realize the rotational connection between the lower connecting rod 12 and the wire clamp 3, an inverted T-shaped adaptation structure is also adopted. Specifically, as Figure 4 and Figure 5 shown, the bottom end of the lower connecting rod 12 has an inverted T-shaped shaft head structure, and the bottom end of the lower connecting rod 12 is adapted to the second inverted T-shaped shaft hole 31 on the wire clamp 3, so as to hang the wire clamp 3 on the component main body 1, and after hanging, the lower connecting rod 12 can rotate around its own axis.

[0040] The wire clamp 3 is a split structure, and after docking and splicing, a second inverted T-shaped shaft hole 31 is formed. The formation structure of the second inverted T-shaped shaft hole 31 is similar to that of the first inverted T-shaped shaft hole. Specifically, the wire clamp 3 can adopt a B-type structure, and the positioning wire clamp of the B-type structure is usually composed of two symmetrical parts. As Figure 5As shown in the figure, a feasible structure of the wire clamp 3 is given, which includes a taper-threaded hexagon nut 32, a left clamp body 33 and a right clamp body 34. The left clamp body 33 and the right clamp body 34 are symmetrical structures. When they are butted together, a second inverted T-shaped shaft hole 31 is formed in the middle. After butt joint, a taper thread is formed at the top in the middle, and they are fixed together by the taper-threaded hexagon nut 32.

[0041] The component body 1 is similar to the main body structure of a conventional elastic insulation suspension component. A rubber elastomer is arranged inside, which has elastic buffering in the axial direction, absorbs the impact energy generated by the current collection of the pantograph and the lifting force during passing, reduces the vertical acceleration of the pantograph, and is used to eliminate local hard point defects. As Figure 6 and Figure 7 shown, it is a schematic structural diagram of a feasible component body 1. The component body 1 includes an umbrella sleeve 13, an upper core body 14, a lower core body 15 and a rubber elastic element 16. The upper connecting rod 11 is fixedly connected to the upper core body 14. The upper core body 14 and the lower core body 15 are elastically connected by the rubber elastic element 16. The lower core body 15 is fixedly connected to the lower connecting rod 12, and the umbrella sleeve 13 is sleeved on the outside. In addition, the axes of the upper connecting rod 11 and the lower connecting rod 12 are collinear, and they are both vertically arranged during installation.

[0042] During installation, first place the two parts of the rotary joint 24 and the upper connecting plate 21 at the corresponding installation positions on the groove bottom plate of the suspension base 4. The rotary joint 24 can rotate freely in the first inverted T-shaped shaft hole; then place the lower connecting plate 22 at the corresponding position on the ground of the groove bottom plate of the suspension base 4; then pass the cap bolt 231 upward through the through holes on the lower connecting plate 22, the groove bottom plate of the suspension base 4 and the upper connecting plate 21, and then fasten it with the fastening nut 232; then pass the upper connecting rod 11 of the component body 1 upward through the through holes on the lower connecting plate 22, the groove bottom plate of the suspension base 4 and the upper connecting plate 22 in sequence, and threadedly engage it through the inner hole of the rotary joint 24; then tighten the rotary fastener 25 on the upper connecting rod 11 to realize the rotational connection of the component body 1 to the connecting member 2.

[0043] After the above installation is completed, install the wire clamp 3 on the lower connecting rod 12. First, sleeve the taper-threaded hexagon nut 32 on the lower connecting rod 12, then butt and fit the left clamp body 33 and the right clamp body 34, and make the second inverted T-shaped shaft hole 31 sleeve the bottom end of the lower connecting rod 12; then tighten the taper-threaded hexagon nut 32 to complete the rotational connection of the wire clamp 3 to the component body 1.

[0044] During use, the component body 1 can rotate freely relative to the conductive rail 5 and the suspension base 4. During use and installation, the conductive rail 5 and the wire clamp 3 can adaptively adjust their positions relative to the component body 1, and the component body 1 can also adaptively adjust its position relative to the suspension base 4, effectively avoiding jamming between the conductive rail 5 and the wire clamp 3. Moreover, during manual inspection during patrol, by manually rotating the component body 1, it can be determined whether jamming occurs. The operation is simple and does not require professional technicians, saving time and effort.
