Description

Technical Field

[0001] The utility model belongs to the technical field of railway contact network construction, and specifically relates to a suspension mechanism and a contact wire disassembly and assembly auxiliary device for railway busbars. Background Art

[0002] Railways or subways generally supply power to trains through buses set above the rails and contact wires installed on the buses. The contact wires are usually tightly clamped in the dovetail grooves at the bottom of the bus. For the disassembly and assembly of the contact wires in the dovetail grooves, a railway bus contact wire disassembly and assembly auxiliary device is usually used. The railway bus contact wire disassembly and assembly auxiliary device usually includes a fixed frame and an expansion mechanism, a suspension support mechanism and a vertical adjustment mechanism set on the fixed frame. The expansion wheels in the expansion mechanism can be respectively clamped in the positioning grooves on both sides of the dovetail groove to achieve the adjustment of the dovetail groove clamping mouth. At the same time, the suspension support mechanism can contact with the limit platform set on the bus and located above the two dovetail grooves, and can be clamped on the bus in the vertical direction together with the expansion mechanism. The vertical adjustment mechanism can push the contact wire upward at the bottom of the fixed frame so that the contact wire enters the expanded dovetail groove.

[0003] In the prior art, the suspension support mechanism usually includes a suspension wheel. However, the suspension wheel is usually adjusted by adjusting the bolt to drive the suspension wheel to move in the width direction of the bus so that it contacts the limit platform or leaves the limit platform. This method is time-consuming and labor-intensive during the construction and disassembly process of the bus. In particular, when there are multiple suspension wheels, each adjusting bolt needs to be rotated one by one, resulting in low installation or disassembly efficiency and poor practicality.

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] Please also read Figures 1 to 3 , the suspension mechanism 40 provided by the utility model is now described. The suspension mechanism 40 includes two groups of suspension components, and the two groups of suspension components are respectively located on both sides of the bus 50, and each group of suspension components includes a plurality of suspension structures arranged at intervals along the length direction of the bus 50. Each suspension structure includes a fixed cylinder 41, a slide column 42, a suspension wheel 43 and a linkage component 44. One end of the fixed cylinder 41 is fixed on the fixed frame 10, and the other end extends outward. The slide column 42 is slidably arranged in the cylinder cavity of the fixed cylinder 41, and one end of the slide column 42 extends toward the bus 50 for rotational connection with the suspension wheel 43. The linkage component 44 is arranged on the fixed cylinder 41 and is connected to the slide column 42. The linkage component 44 has a flipping part, and the linkage component 44 can pull the slide column 42 to slide after the flipping part is bent.

[0027] Compared with the prior art, the suspension mechanism 40 provided in this embodiment has two sets of suspension components respectively located on both sides of the bus 50 corresponding to the limit platforms 52 on both sides of the bus 50, and each suspension component is provided with multiple suspension structures, which can ensure the stability of the connection and movement of the contact wire disassembly and assembly auxiliary device for railway bus and the bus 50. Each suspension structure can be operated by the flip part in the linkage component 44, so that the linkage component 44 pulls the sliding column 42 to slide close to the bus 50 or away from the return bar. This structure is easy to operate and can effectively reduce the time for disassembly and assembly of the suspension structure, thereby improving the assembly and disassembly efficiency of the contact wire disassembly and assembly auxiliary device for railway bus and the bus 50, saving time and labor, and having strong practicality.

[0028] In some embodiments, the linkage component 44 may be implemented as follows: Figures 2 to 3 See the structure shown. Figures 2 to 3 Each linkage component 44 includes a fixed shaft 441 fixed on the fixed cylinder 41, a flip block 442 rotatably connected to the fixed shaft 441, and a connecting rod 443 connecting the flip block 442 and the sliding column 42.

[0029] Specifically, the axis of the fixed shaft 441 is perpendicular to the axis of the fixed cylinder 41 .

[0030] Specifically, the flip block 442 is a flip part, and a hinge shaft for the connecting rod 443 to be hinged is provided on the flip block 442. The hinge shaft is parallel to the fixed shaft 441 and is spaced apart. The flip block 442 also has a connecting end.

[0031] The flip block 442 is bent by the connecting end to make it flip around the fixed axis 441, and then the sliding column 42 is pulled or pushed to slide through the hinge axis on the flip block 442. It has a simple structure and is easy to operate, and can improve the disassembly and assembly efficiency of the suspension wheel 43 and the limiting platform 52.

[0032] In some embodiments, the fixed shaft 441 may be Figure 2 See the structure shown. Figure 2 The axis of the fixed shaft 441 is arranged along the length direction of the bus 50. Because the bus 50 is located at a higher position, when the axis of the fixed shaft 441 is arranged along the length direction of the bus 50, the flip block 442 is in a pitch rotation, which can be more convenient to operate.

[0033] In some embodiments, the suspension assembly may be configured as follows: Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2 Each set of suspension components further includes a handle 46, which has a plurality of docking ends corresponding to each flip block 442, and each docking end is fixedly connected to each connecting end. The setting of the handle 46 can ensure that the plurality of flip blocks 442 in each set of suspension components can be operated simultaneously, thereby ensuring that each suspension wheel 43 simultaneously contacts the limiting platform 52 or leaves the limiting platform 52, which can further improve the installation efficiency of the contact wire disassembly and assembly auxiliary device for railway busbar and the busbar 50.

[0034] In some embodiments, the flip block 442 may be implemented as follows: Figure 3 See the structure shown. Figure 3 The line connecting the connecting end to the fixed shaft 441 and the line connecting the hinge shaft to the fixed shaft 441 are set at an angle. This structure can ensure that after the flip block 442 rotates a small angle, the sliding column 42 can be pulled or pushed, which can improve the disassembly and assembly efficiency to a certain extent.

[0035] Preferably, see Figure 2 When the line connecting the connecting end and the fixed shaft 441 is perpendicular to the axis of the barrel, the sliding column 42 is pushed by the flip block 442, and the sliding column 42 moves close to the bus 50, so that the suspension wheel 43 contacts the limiting platform 52. When the line connecting the connecting end and the fixed shaft 441 is in the same direction as the axis of the barrel, the sliding column 42 is pulled by the flip block 442, and the sliding column 42 moves away from the bus 50, so that the suspension wheel 43 is separated from the limiting platform 52.

[0036] In some embodiments, the fixing tube 41 may be Figure 3 See the structure shown. Figure 3 The extended end of the fixed cylinder 41 is provided with a notch for the turning block 442 to pass through during the turning process. The notch is located on the side wall of the fixed cylinder 41 and is connected to the cylinder cavity.

[0037] The provision of the notch can facilitate the turning of the turning block 442 and avoid interference with the turning block 442 .

[0038] Preferably, the notch is located at the lower end of the fixing tube 41, as shown in FIG. Figure 3 .

[0039] In addition, it should be explained that the linkage assembly has a self-locking function. When the line connecting the connection end and the fixed shaft 441 is perpendicular to the axis of the fixed cylinder 41, it is flipped to the maximum angle, and the flip block 442 abuts against the top of the inner wall of the cylinder cavity. At this time, the length direction of the connecting rod 443 is set along the axis direction of the fixed cylinder 41, or the end of the connecting rod 443 hinged to the hinge shaft is higher than the end of the connecting rod 443 hinged to the sliding column 42. This structure can avoid the reverse push of the sliding column 42 and the suspension wheel 43, so that the flip block 442 flips in the opposite direction, and prevents the suspension wheel 43 from automatically detaching from the limit platform 52 when working.

[0040] In some embodiments, the suspension wheel 43 and the slide post 42 may be used as follows: Figure 3 See the structure shown. Figure 3 A rolling bearing 45 is provided between the suspension wheel 43 and the slide column 42 . This structure can ensure the rolling connection between the suspension wheel 43 and the slide column, thereby ensuring the smooth rotation of the suspension wheel 43 .

[0041] In some embodiments, the fixing tube 41 may be Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2 The fixing tube 41 and the fixing frame 10 are connected by bolts. This structure has a simple connection structure and is easy to manufacture and assemble.

[0042] The utility model also provides a contact wire disassembly and assembly auxiliary device for railway busbar, which can be seen in Figure 1 , Figure 4 and Figure 5 The contact wire disassembly and assembly auxiliary device for the railway bus includes a fixing frame 10 for the bus 50 to pass through, a wire pushing mechanism 20 arranged at the bottom of the fixing frame 10, an expansion mechanism 30 arranged at the bottom of the fixing frame 10, and the above-mentioned hanging mechanism 40 that can clamp the bus 50 together with the expansion mechanism 30.

[0043] The utility model also provides a contact wire disassembly and assembly auxiliary device for railway busbars. Compared with the prior art, the connection and movement stability of the contact wire disassembly and assembly auxiliary device for railway busbars and the busbar 50 can be ensured by setting a suspension mechanism 40. At the same time, the operation is convenient, and the disassembly and assembly time of the suspension mechanism 40 can be effectively reduced, thereby improving the assembly and disassembly efficiency of the contact wire disassembly and assembly auxiliary device for railway busbars and the busbar 50, saving time and labor, and having strong practicality.

[0044] In some embodiments, see Figure 1 , Figure 4 and Figure 5 The fixing frame 10 can secure two vertical plates 11 located on both sides of the bus 50 and a connecting member 12 connecting the two vertical plates 11. The connecting member 12 can be a connecting rod connecting multiple connecting rods, each connecting rod is distributed on both sides of the expansion mechanism 30 along the length direction of the bus 50. For the fixing cylinder 41 on the suspension mechanism 40, it is fixedly connected to the vertical plate 11, and a corresponding through hole is opened on the vertical plate 11 for the sliding column 42 to pass through.

[0045] In some embodiments, see Figure 1 and Figure 4 The expansion mechanism 30 includes an adjusting shaft 31, which drives two bearing seats 32 slidingly connected to the fixed frame 10 to move relative to or away from each other through a bidirectional thread during adjustment. Each bearing seat 32 is connected to an expansion wheel 33 through a bearing, and the two expansion wheels 33 are correspondingly arranged with two positioning grooves 53. The expansion structure is a prior art and will not be described in detail here.

[0046] In some embodiments, see Figure 1 and Figure 5 The wire pushing mechanism 20 may include two cross beams 21 of two vertical plates 11, an adjusting screw 22 arranged along the vertical direction and threadedly connected to the cross beam 21, a wheel seat 23 is provided at the top of the adjusting screw 22, and a push roller 24 is rotatably connected in the wheel seat 23. This structure can mainly ensure that the roller pushes the release wire into the dovetail groove 51. This technology is a prior art and will not be repeated here.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
