Description
Technical field
The present invention relates to railway tunnel Disease Treatment construction workplatform, specifically a kind of Tunnel Engineering train formula fast lifting folding work platform.
Background technology
Can there is disease in various degree in service time longer railway tunnel, especially for railway electrifing reforming engineering, need electric power contact system linked network in tunnel, then first the tunnel of disease must be carried out the comprehensive regulation. at present, tunnel regulation is general adopts the simple and easy workplatform of dismounting formula, the general structure of platform is: the framework making a 2m �� 2m, arrange 4 little wheels below framework to contact with rail top face, can at rail top face sliding, scaffolding steel pipe is utilized to set up the square workplatform of 1.8m �� 1.8m above framework, podium level needs to set up according to operation height, usually two job platforms are linked into one group of use, this kind of method generally starts in Window time after track traffic is blocked assembled, move to again after neighbouring operation point is reinforced again and start operation, and need before predetermined track traffic is open, remove from track and remove all facilities. weak point one is that simple rack weight is light, center of gravity height, not too safe, two is that each track traffic blocking time section interior dismounting activity duration is long, and effective engineering time is short, and especially for transporting main line frequently, traffic is precious especially for off-period, three is cost height, and it is that one repeats work that simple and easy workplatform all to be carried out dismounting by every subjob, and traffic can not get sufficient utilization off-period, causes personnel's work holdup.
Summary of the invention
Need the long-time problem interrupting railway operation when the present invention is directed to current tunnel Disease Treatment, and a kind of Tunnel Engineering train formula fast lifting folding work platform in place fast is provided.
The present invention solves the technical scheme of described problem employing:
A kind of Tunnel Engineering train formula fast lifting folding work platform, comprise track flat-bed trailer, platform primary truss, lifting gantry and folding platform, described platform primary truss is fixed on track flat-bed trailer base plate, described lifting gantry column telescoping is sleeved on described platform primary truss column, and described folding platform support is hinged on described platform primary truss column.
Further, described platform primary truss column and described lifting gantry column are sleeve type structure, both are locked by corresponding pin-and-hole bearing pin, having on platform primary truss column erects to chute, upper end is hung with chain block by weldering ear connecting plate, lifting gantry column lower end be welded with for hanging point under described chain block and can described erect in chute slip draw plate.
Further, described folding platform is positioned at described platform primary truss both sides, every side has upper and lower two layers, the inner of folding platform support is hinged by rotating pin and platform primary truss column, the pin-and-hole keying on wireline and lifting gantry column is drawn to fix by leading when the outer end of upper strata folding platform support is opened, by movable latch and the draw ring temporary locking being welded on platform primary truss column time folding; The draw ring drawknot on wireline and platform primary truss column is drawn to fix by leading when the outer end of lower floor's folding platform support is opened, by movable latch and the draw ring temporary locking being welded on platform primary truss column time folding.
Further, described lifting gantry and described folding platform surrounding are respectively arranged with safe guardrail.
Further, on the truss sheet of described platform primary truss and on the athwartship plane of described lifting gantry, cat ladder is housed respectively.
Compared with prior art, often to save, track flat-bed trailer uses as cellular installation in the present invention, during engineering train operation, lifting part can be down to lowest part by job platform, and both sides foldable portion packs up locking simultaneously, it is ensured that do not exceed vehicle gauge of the locomotive; Workplatform foldable portion is opened and is fixed after driveing to tunnel operation point by engineering train, promotes workplatform to correct position according to single position, two-wire tunneling operation face simultaneously; Engineering train can move to job location fast, and in train length range, big area launches construction, blocks before point terminates and returns bus stop in time. Therefore, the present invention can make full use of effectively " skylight " time, accelerating construction progress, engineering train is promoted comprehensively and exits simultaneously, can guarantee to disappear in time a little, it is ensured that existing alignment car safe operation on schedule, can significantly reduce the repetition activity duration, save through engineering cost, ensure construction safety.

Embodiment
Below in conjunction with embodiment, the invention will be further described, and object is only to understand content of the present invention better.
Tunnel Engineering train formula fast lifting folding work platform described in the present embodiment, taking track flat-bed trailer base plate 13 as mounting seat, often saving track flat-bed trailer is an independent operation unit, it is possible to arbitrary combination forms multiple operation unit.
FIGS, platform primary truss is made up of forward and backward truss sheet and the ridge directional brace 20 that connects forward and backward truss sheet, platform primary truss is connect as bottom girder and track flat-bed trailer base plate 13 bolt by channel-section steel, platform primary truss column 8 and top end rail 15 adopt steel pipe manufacturing, having on platform primary truss column 8 and erect to chute 12, platform primary truss column 8 upper end is hung with chain block 6 by weldering ear connecting plate 17. Being sleeved in the platform primary truss column 8 of steel pipe manufacturing by the lifting gantry column 2 of steel pipe manufacturing equally, plate 14 is drawn in the welding of lifting gantry column 2 times ends, for the lower hanging point of chain block 6, draws plate 14 can to slide up and down in chute 12 erecting. Position corresponding on platform primary truss column 8 and lifting gantry column 2, it is drilled with pin-and-hole 19 by same intervals distance, when lifting gantry 1 needs to rise, tighten up chain block 6, lifting gantry column 2 upwards moves under the drawing high drawing plate 14, during to the height needed, insert, with bearing pin, the position that pin-and-hole 19 can fix lifting gantry 1.
Platform primary truss both sides arrange upper and lower two layers of folding platform 4 respectively, the inner of upper strata folding platform support 5 and lower floor's folding platform support 11 is hinged by rotating pin 9 and platform primary truss column 8, draw wireline 3 to fix with pin-and-hole 18 keying on lifting gantry column 2 by leading when the outer end of upper strata folding platform support 5 is opened, led with being welded on by movable latch 10 time folding and draw wireline 3 draw ring 7 temporary locking; Wireline 3 is drawn to fix with draw ring 7 drawknot on platform primary truss column 8 by leading when the outer end of lower floor's folding platform support 11 is opened, by movable latch 10 and draw ring 7 temporary locking being welded on platform primary truss column 8 time folding. When folding platform 4 is opened by needs, pull open movable latch 10, manually folding platform 4 is opened, wireline 3 and draw ring 7 drawknot on platform primary truss column 8 are drawn by leading in lower floor's folding platform support 11 outer end, the outer end of upper strata folding platform support 5 by lead draw wireline 3 keying on lifting gantry column 2 pin-and-hole 19.
Lifting gantry 1 and folding platform 4 completely spread formation job platform by plank, platform surrounding establishes the safe guardrail 16 being highly not less than 1.05m, during engineering train operation, lifting gantry 1 is down to lowest part, both sides folding platform 4 packs up locking simultaneously, can guarantee not exceed vehicle gauge of the locomotive.
