Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical solutions of the utility model are described in further detail, described concreteEmbodiment only explains the utility model, not in order to limit the utility model.
As shown in Figure 1, Figure 2 and Figure 3, a kind of closed construction for the old bridge anticollision barrier construction of overcrossing railway of the utility modelPlatform, comprises main couple 1, and described main couple 1 adopts triangular truss structure, and assembled by square steel, be welded, described inIn main couple 1, be provided with cross rib, adopting triangular truss structure and being provided with cross rib is mainly to strengthen operation platform overall structureStability. The bottom of described main couple 1 is provided with wheel 2, and the wheel 2 that is arranged on described main couple 1 bottom is at least two groups,Every group is coaxial setting, and in a word, the configuration of wheel 2 will adapt with the track 9 of the old bridge bridge floor of railway. When construction, construction is flatPlatform can move along bridge floor; The rear side of described main couple 1 is provided with column 3, the top of described main couple 1 be provided with forward extend theOne support 4 and extend back second support 5,4 front end, first are supported with described first respectively in the top of described column 3Between the rear end of the middle part of support and the second support 5, be provided with respectively suspension cable 6, the front end that is positioned at described the first support 4 is provided with plug-inBasket 7, the bottom surface of described external basket 6 and side are provided with fully closed composite plate, and described composite plate comprises the bamboo glue of laminating successivelyPlate, anti-electrical insulation pad and zinc-plated galvanized iron sheet, described external basket 6 has four connected sides, wherein, away from main couple 1The height of side and two sides being adjacent is consistent, is less than the height of other sides near the height of the side of main couple 1,As long as the height of this side meets and can block platform under duty and (can adopt and be ridden against as shown in Figure 4 anticollision barrierOn 10), the article that prevent, such as construction material and instrument etc., fall to play the article that prevent on platform; Described main trussFrame 1 and second is provided with counterweight frame 8 between supporting 5, to ensure that operation platform can keep poised state.
The utility model operation platform is assembled completing outside running railway line, before mobile this platform, it done to check comprehensively, heavyThe support connecting piece of point to platform, connecting bolt, bearing pin, outside attachment etc. carry out comprehensive security inspection, thoroughly remove flat, while guaranteeing platform movement walking, there is not object and fall in the outside unnecessary attachment of platform. Mobile front in bridge floor track and shift positionCarry out mark, determine the particular location that platform is in place. Platform movement adopts the artificial loading machine traction merogenesis that coordinates to advance, mobileIn process, strengthen the observation to platform movement track, orbit displacement occurs and adjust in time.
As shown in Figure 4, before construction, this platform is pushed behind railway top, can not be subject to railway to block skylight restriction and carry out whole day groupKnit construction, improved construction efficiency. Wheel 2 is in the interior rolling of track 9, by platform movement to precalculated position, by platform endSpace sealing between portion both sides and anticollision barrier 10, prevents that in work progress, object falls. The ground connection dress of platform is set simultaneouslyPut. Pay special attention to check between platform and the piece of platform end, and cleaning fall into the object in platform at any time, prevents brokenPiece falls under bridge within the scope of railway. Protecting screen in the time that reaching designing requirement, is installed anticollision barrier concrete strength in time.
After the project of implementing in platform all completes, just can be by platform movement to next operation side, platform movement existsImplement in train travel gap, and after whole anticollision barrier has all been constructed, platform movement to running railway line is removed outward, removesHanging Basket is consolidation service inverse process.
Adopt the utility model chemical industry platform carry out all construction process of old bridge anticollision barrier (comprise the dismounting of old anticollision barrier →Installation → concreting → form removable → the concrete curing of unwrapping wire → reinforcement installation → template is cleared up → is measured in substrate) all existIn closed platform, complete. While workmen clears up foreign material and security monitoring is also carried out in closed platform, thereby in constructionIn process, stopped the possibility that object falls, gets an electric shock, construction safety is protected.
Although by reference to the accompanying drawings the utility model is described above, the utility model is not limited to above-mentioned concreteEmbodiment, above-mentioned detailed description of the invention is only schematically, instead of restrictive, the ordinary skill people of this areaMember, under enlightenment of the present utility model, in the situation that not departing from the utility model aim, can also make a lot of distortion, thisWithin all belonging to protection of the present utility model a bit.
