Technical field
The present invention relates to railway tunnel disease regulation construction working platform, specifically a kind of construction of tunnel train formula fast lifting folding work platform.
Background technology
Can there be disease in various degree in long railway tunnel of service time, especially for railway electrifing reforming engineering, needs electric power contact net linked network in the tunnel, then must carry out the comprehensive regulation in first tunnel to disease.At present, the general simple and easy working platform of reassembling type that adopts of tunnel regulation, the general structure of platform is: the framework of making a 2m * 2m, 4 trundles are set below the framework to be contacted with rail top face, can slide movement in rail top face, utilize scaffolding steel pipe to set up the square working platform of 1.8m * 1.8m above the framework, podium level is set up according to the operation height needs, usually two job platforms are linked into one group of use, this method generally skylight after track traffic is blocked begins assembly unit in the time, begin operation after near moving to again setting is reinforced again, and need before predetermined track traffic is open, remove all facilities from the track dismounting.Weak point one is that simple rack is in light weight, center of gravity is high, and is not too safe; The 2nd, the interior dismounting activity duration of each track traffic blocking time section is long, and effective engineering time is short, and especially for transporting main line frequently, traffic is precious especially off-period; The 3rd, the cost height, it is a kind of duplication of labour that each operation all will be carried out dismounting to simple and easy working platform, traffic can not get sufficient utilization off-period, causes personnel's work holdup.
Summary of the invention
The present invention is directed to needs long-time problem of interrupting railway operation when present tunnel defect is renovated, and a kind of construction of tunnel train formula fast lifting folding work platform in place fast is provided.
The technical scheme that the present invention solves described problem employing is:
A kind of construction of tunnel train formula fast lifting folding work platform, comprise track flat car, platform main couple, lift platform and folding platform, described platform main couple is fixed on the track flat car base plate, described lift platform column extension type is sleeved on the described platform main couple column, and described folding platform support is hinged on the described platform main couple column.
Further, described platform main couple column and described lift platform column are sleeve type structure, both lock with bearing pin by corresponding pin-and-hole, have vertical chute on the platform main couple column, the upper end is hung with Chain block by the welding otic placode, and the lift platform column lower end is welded with the arm-tie that also can slide for hanging point under the described Chain block in described vertical chute.
Further, described folding platform is positioned at described platform main couple both sides, every side has upper and lower two-layer, the inner of folding platform support is hinged by rotating pin and platform main couple column, fix by the pin-and-hole keying on tractive wire rope and the lift platform column when open the outer end of upper strata folding platform support, lock by movable latch and the draw ring that is welded on the platform main couple column when folding temporarily; Fix by the draw ring drawknot on tractive wire rope and the platform main couple column when open the outer end of lower floor's folding platform support, lock by movable latch and the draw ring that is welded on the platform main couple column when folding temporarily.
Further, be respectively arranged with safety barrier around described lift platform and the described folding platform.
Further, on the truss sheet of described platform main couple and on the athwartship plane of described lift platform cat ladder is housed respectively.
Compared with prior art, the present invention is that the unit is installed and used with every joint track flat car, during the engineering train operation, the job platform liftable partly is down to lowest part, and the both sides foldable portion is packed up locking simultaneously, guarantees not exceed vehicle gauge of the locomotive; Engineering train leaves to the tunnel behind the setting, the working platform foldable portion is opened and is fixed, and promotes working platform to correct position according to single double track tunnel scope of operation position simultaneously; Engineering train can move to the job location fast, and large tracts of land is launched construction in the train length range, blocks and in time returns bus stop before point finishes.Therefore, the present invention can take full advantage of effectively " skylight " time, accelerating construction progress, engineering train is promoted comprehensively and is withdrawed from simultaneously, can guarantee in time to disappear a little, guarantees the safe operation of existing line train running on scheduled time, can reduce the repetition activity duration significantly, joint guarantees construction safety through engineering cost.
