[0063] In order to make the technical solutions and advantages of the present utility model clearer and more understandable, the exemplary embodiments of the present utility model are further described in detail below with reference to the attached drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than an exhaustive list of all embodiments. And without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0064] A ballast track refers to a track with a stone granular ballast bed under the rail, usually also called a crushed stone ballast track, which is one of the main forms of track structure. It has the advantages of good elasticity, low price, convenient replacement and maintenance, and good noise absorption characteristics.

[0065] According to the operation practice of ballasted tracks in China, the working conditions of ballasted track lines are generally good. However, affected by various factors such as poor construction, uneven settlement of the foundation, upheaval of the tunnel floor, reciprocating loads of trains, rain and snow erosion, and environmental temperature, some diseases and damages will inevitably occur in the track structure, resulting in poor geometric alignment of the line and endangering the driving safety of trains.

[0066] The causes of tunnel floor diseases are complex and the rectification is difficult, which not only seriously affects the safety of railway operation, but also brings many difficulties to the maintenance work of track structure.

[0067] In view of the serious tunnel floor diseases, at present, technologies such as D-beams, profiled steel beams, and tie-down rails are often used to disassemble and replace the tunnel floor. However, the above structures have problems such as heavy structure, long construction period, and high cost. For the ballasted track damage caused by the upheaval of the tunnel base structure over a large area, a scheme of replacing the tunnel floor structure is required. For the disassembly and replacement of the tunnel base structure of ballasted tunnels, the line needs to be overhead.

[0068] To solve the above problems, the present utility model proposes a ballasted track line overhead device to solve the problem that the line needs to be overhead when disassembling and replacing the tunnel base structure of ballastless tunnels.

[0069] In the embodiment as Figure 1 shown, a ballasted track line overhead device includes:

[0070] A steel cushion beam 100, the steel cushion beam 100 includes two parallel constant-size box-section longitudinal beams 110;

[0071] Cross beams 120 connecting the longitudinal beams 110, the cross beams 120 include two end cross beams 121 and two intermediate cross beams 122, the end cross beams 121 are connected to both ends of the longitudinal beams 110, and the intermediate cross beams 122 are arranged in the middle of the longitudinal beams 110;

[0072] Wherein, fasteners 300 are arranged on the longitudinal beams 110 of the steel cushion beam 100, and the rails 200 are installed through the fasteners 300.

[0073] In the line overhead device according to this embodiment, the steel cushion beam 100 is used to overhead the scope of the tunnel floor structure disassembly and replacement project. The steel cushion beam 100 includes longitudinal beams 110 and cross beams 120. To ensure that the anchor bolts of the beam end position limiting device have sufficient distance from the edge of the support layer and prevent the concrete edge from being damaged under the action of lateral swaying force, and at the same time ensure that the beam body has sufficient vertical stiffness, the longitudinal beams 110 adopt variable-size box sections.

[0074] In one embodiment, the fasteners 300 are connected to the steel cushion beam 100 by bolts;

[0075] Moreover, a rubber cushion plate 301 and an O-shaped nylon cushion plate 302 are further provided between the fastener 300 and the steel cushion beam 100.

[0076] A rubber cushion plate 301 and an O-shaped nylon cushion plate 302 are further provided between the fastener 300 and the steel cushion beam 100. An insulating sleeve 304 is provided on a bolt 303 connecting the fastener 300 and a cross plate 111 of the steel cushion beam 100. The sleeve 304 includes a T-shaped insulating sleeve sleeved on the iron cushion plate and an O-shaped insulating sleeve provided on the cross plate 111. An O-shaped insulating cushion plate is provided on the lower surface of the cross plate 111 of the steel cushion beam 100.

[0077] In addition to playing a role in vibration reduction, the O-shaped nylon cushion plate more importantly plays an insulating function. The purpose is to keep the rail 200 and the steel cushion beam 100 in a non-electrically connected state, ensuring that there is no "red band" in the track circuit. Once a "red band" appears, the signal lights are all red and the trains have to stop completely and cannot pass.

[0078] The O-shaped nylon sleeve and the T-shaped nylon sleeve further play an insulating role to prevent the bolt from conducting electricity.

[0079] In one embodiment, supports 130 are provided at both ends of the steel cushion beam 100, and limit members are provided on both sides of the supports 130.

[0080] In one embodiment, the limit member includes an angle steel main body. A triangular reinforcing rib 132 is provided inside the angle steel main body 131, and the angle steel main body 131 is connected to the steel cushion beam 100 by bolts.

[0081] In one embodiment, the support 130 includes a steel plate and a rubber bearing plate 135 provided on the steel plate.

The rubber bearing plate 135 plays the role of bearing pressure and damping vibration, and the steel plate provides support strength. The steel plate is divided into two structural forms: the first steel plate 133 and the second steel plate 134. When installing the support 130, the first steel plate 133 and the second steel plate 134 can be appropriately combined according to the actual required height of the support 130.

Finally, the rubber bearing plate 135 is placed in the groove 136 on the top surface of the first steel plate 133. When the height of the first steel plate 133 does not meet the requirements, the second steel plate 134 with an appropriate thickness can be stacked under the first steel plate 133 to adjust the height of the support 130.

[0091] In one embodiment, the longitudinal beam 110 includes an upper cross plate 111 and a lower cross plate 112. Both the upper cross plate 111 and the lower cross plate 112 are plate-like structures, similar in shape, and arranged vertically aligned.

[0092] Between the upper cross plate 111 and the lower cross plate 112, two columns of vertical plates 113 are arranged.
