Description
Technical Field
The utility model relates to a track traffic technical field, concretely relates to track traffic tunnel top damping crane span structure device of crossing rail.
Background
According to the specification of 15.4.11 in the subway design Specification GB50517-2013, when the cable passes through the track, the cable can be laid by passing a hard non-metal pipe under the track or by laying along the top of the tunnel in a rigid fixing mode. At present, if a cable is laid by adopting a track downward-penetrating mode, due to the severe environment of a track traffic underground construction site, long construction period and various cross operations, pipes reserved in downward-penetrating tracks are always left almost due to the reasons of breakage, concrete blockage, artificial damage and the like. If the scheme of crossing the tracks at the top is adopted, namely the common mode of rigidly fixing the anchor bolts and the bridge frame at the top of the tunnel structure is adopted. When the train moves, the train vibrations arouse tunnel structure vibrations, and tunnel piston wind transversely strikes top crane span structure, and these all can great influence top crab-bolt's fixed reliability, along with operation time's the process, the not hard up risk of rigid fixation crab-bolt increases gradually, under the effect of gravity, if the crane span structure in case falls, will produce great influence to the normal operation of circuit.
At present, no better solution is available for the overhead rail-passing bridge of the rail traffic tunnel at home and abroad.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide a track traffic tunnel top damping crane span structure device of crossing rail reasonable in design, can overcome the randomness of the nonstandard construction installation method of the fixed crane span structure of tunnel top rigidity, improved the installation quality, guaranteed fixed reliability to for the maintenance in operation later stage provides maneuverability, and simple structure, installation convenient to use, industrialization popularization prospect is very wide.

The specific implementation mode is as follows:
the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to fig. 6, the following technical solutions are adopted in the present embodiment: the device comprises a chemical anchor bolt 1, a hinge 2, a longitudinal damper 3, a transverse damper 4, a U-shaped bracket 5 and a cable bridge 6; the two ends of the hinge 2 are fixed at the top of the tunnel by using a chemical anchor bolt 1, a hinge hole at the upper end of the longitudinal damper 3 and a hinge hole of the hinge 2 are coaxially arranged and are fixedly connected by using a bolt, a hinge hole at the lower end of the longitudinal damper 3 and a hinge hole at the middle part of the transverse damper 4 are coaxially arranged and are connected by using a bolt, bolt holes at the two ends of the transverse damper 4 and bolt holes at the upper end of the U-shaped bracket 5 are coaxially arranged and are fixedly connected by using a bolt; the cable tray 6 is arranged in the U-shaped bracket 5.
The installation mode and the working principle of the specific embodiment are as follows: firstly, two chemical anchor bolts 1 penetrate through side holes of a hinge 2 to fix the hinge 2 on a tunnel top structure; aligning the hinge hole at the upper part of the longitudinal damper 3 with the hinge hole of the hinge 2 and fastening the hinge hole through a bolt, and aligning the hinge hole at the lower part of the longitudinal damper 3 with the hinge hole at the upper part of the transverse damper 4 and fastening the hinge hole through a bolt; then the cable bridge 6 is placed in the U-shaped bracket 5; finally, bolt holes on the left side and the right side of the transverse damper 4 are aligned with bolt holes on the two sides of the U-shaped bracket 5 and fixed through bolts, all the components are combined and fixed into a whole, the over-track cable 7 is erected on the cable bridge frame 6, when a train normally runs, a tunnel structure vibrates along with the running of the train, the longitudinal damper 3 is used for weakening the longitudinal acting force of bridge frame gravity on the chemical anchor bolt 1 when the structure vibrates, meanwhile, tunnel piston wind can generate larger lateral wind pressure on the bridge frame, the transverse damper 4 is used for weakening the transverse acting force of the piston wind lateral pressure sensing to the chemical anchor bolt 1 on the top structure of the tunnel, namely the longitudinal damper 3 and the transverse damper 4 act together, and the over-track cable 7 is safely and reliably lifted.
