Specific embodiment
Below in conjunction with the accompanying drawings, describe the technical solution of the utility model in detail.
As shown in figure 1, the mobile working platform of continuously can constructing for rail tunnel of the present utility model, including it is fast Fast building work platform 1, travel(l)ing rest 3, flat jack 5 and supporter 6.As shown in Fig. 2 fast assembling workbench 1 includes quickly Building work platform skeleton 11, stop 12 and shaft sleeve 13.Fast assembling workbench skeleton is using steel pipe or compo pipe Built by assembling mode.Fast assembling workbench skeleton 11 includes being located at rectangle or square same plane respectively The four vertical root posts of four vertex positions, if fast assembling workbench is longer, can be in two along track direct of travel Intermediolateral column is added in the middle of column, the number of intermediolateral column is preferably 1-4 roots, is respectively welded shaft sleeve 13 and uses on every root post In the stop 12 for limiting 3 rotational angle of travel(l)ing rest, stop 12 is used to limit 3 rotational angle of travel(l)ing rest, stop 12 Below shaft sleeve 13, the two spacing range is 40-60cm, preferably 50cm, when travel(l)ing rest 3 and stop 12 connect When tactile, travel(l)ing rest 3 just can not be rotated further.Be additionally provided between the two root posts of track direct of travel upper beam and under Cross coupling is additionally provided between portion's crossbeam, and the two root posts, to strengthen fixing force and stability, between two upper beams Erection has for carrying the article carrying platform 2 of load, and lower beam is by support body supports on track.Supporter 6 is preferably grown The bar shaped lumps of wood, its length just can be stuck between fast assembling workbench 1 and track or sleeper, in addition it is also possible to use prop up The support member of support metal tube or other shapes or material.
In order to ensure the bearing capacity of article carrying platform 2, which is preferably sheet metal or three-ply board of the thickness more than 1cm.In order to Safety is improved, 2 surface of article carrying platform is provided with skid resistance strip or anti-skid bulge, prevents the operating personnel above from sliding into.Loading The corner of platform 2 is connected with fast assembling workbench 1 by bolt.In order to be further ensured that bearing capacity and safety, at two Also setting up between upper beam has some support bars, and article carrying platform 2 is supported by support bar, and article carrying platform 2 is apart from rail top face Distance be 3-4.5m, in such as Fig. 5, if section is circular cross section (internal diameter 6m), distance of the article carrying platform 2 apart from rail top face For 3-4.5m;If section is u-shaped cross-section (wide 7.5m, high 8.15m), then preferred distance of the article carrying platform 2 apart from rail top face For 3-6m 6m).In order that this platform can be moved using track, and support can be rotated with 180 °, in order to avoid under the influence of The constructing tunnel vehicle of Fang Yunhang.
As shown in figure 3, travel(l)ing rest 3 includes the rotating shaft skeleton 34 of " U " type, its corner connects for arc, in order to strengthen Bearing capacity, stability, increase the service life, 34 preferred metal tube of rotating shaft skeleton, the chamfering of corner range preferably from 60 °- 90°.The two ends of rotating shaft skeleton 34 are connected to rotating shaft 31, and rotating shaft 31 is adapted with shaft sleeve 13, rotating shaft 31 is inserted and is turned In shaft sleeve 13, travel(l)ing rest 3 is made to be connected with fast assembling foot rest 1, the two can be connected with bearing or latch.3 energy of travel(l)ing rest Enough 31 to be rotated around the shaft, its angle rotatable is 180 °:When travel(l)ing rest 3 is rotated up, after contacting with article carrying platform 2, Rotating shaft skeleton 34 is fixed together with fast assembling workbench skeleton 11 using buckle or band;When travel(l)ing rest 3 to During lower rotation, can not be rotated further after touching stop 12.The bottom welding of rotating shaft skeleton 34 has a roller 32, roller for Track contacts so that the platform can roll movement, and being respectively provided on two sides with of roller 32 can prevent roller 32 from rail The protuberance of landing, is connected with dismountable beam 33 between 34 both sides of rotating shaft skeleton, dismountable beam 33 is wooden or hollow Pipe metal tube, is connected with rotating shaft skeleton 34 by knot that can be undone by a pull, can be installed in the short period of time or be removed, why be designed as Dismountable structure, be in order in working order when make the height that stays of lower section high as far as possible.The dismountable beam 33 of travel(l)ing rest 3 Perpendicular to track direct of travel.In order to ensure the effect of platform, when platform in as Fig. 6 state when, i.e., travel(l)ing rest with limit When position device is contacted, distance of distance of the article carrying platform 2 away from shaft sleeve 13 with shaft sleeve 13 away from rail top face is equal, activity The height of frame is half of the article carrying platform 2 to rail top face height.
As shown in figure 4, flat jack 5 includes flat jack main body 51 and drag hook 52, flat jack main body 51 is by four steel Bar is connected through the hinge and forms, and four steel bars have four summits, the coupler body that drag hook 52 is included pull bar and is connected with pull bar one end, The other end of pull bar is respectively connected by welding manner two summits relative with flat jack main body 51, two coupler bodies respectively with Dismountable beam is connected, and two other summit is connected by threaded rocking handle, and by shaking rocking handle, flat jack main body 51 can To extend or shrink.
In addition it is also possible to use the hydraulic pressure/motor-driven jack of the two ends with drag hook or assembly pulley of axial stretching to replace Flat jack 5 is used as stretching device.
Stair 4 can be provided with, workmen is up and down by speeling stairway 4, in addition it is also possible to by outside ladder Platform, ladder etc. are climbed up and down.4 top of stair is suspended in the upper beam of fast assembling workbench skeleton 11 by hook, building Terraced bottom is fixedly connected with the lower beam of fast assembling workbench skeleton 11 using buckle or band.For the ease of climbing, The ladder height scope of two adjacent crossbeam compositions of stair is 20cm~40cm.
The operation principle of the platform is as follows:In the Construction in Preparatory Stage shown in Fig. 1, four 6 one end of supporter are against soon At the crossbeam of fast 1 bottom of building work platform, the other end is against track or sleeper bottom, such that it is able to limit fast assembling work The rotation of platform 1.Now flat jack 5 does not stress, and can together pull down with dismountable beam 31 standby.Again by the work of platform both sides Dynamic support 3 is pushed up, after which is contacted with article carrying platform 2, it is possible to use buckle or band etc. are by itself and fast assembling The column of workbench skeleton 11 is mutually fixed, and to facilitate walking about for lower section personnel, and reserves passage for transport goods.Workmen can By carrying out construction operation on article carrying platform 2 on stair 4, form such as Fig. 5 institutes of article carrying platform are now may move in tunnel Show.
When end of constructing at needs to be transferred to next place job location, first travel(l)ing rest 3 is put down, track is ridden over On, and standby dismountable beam 31 and flat jack 5 are assembled, now form is as shown in Figure 1.Staff enters work Make platform interior, by the rocking handle for shaking flat jack main body 51, make two drag hooks 52 close to each other, so as to drive travel(l)ing rest 3 is close to each other, the lifting upwards of fast assembling workbench 1, and roller 32 is departed from track.When travel(l)ing rest is contacted with stop 12 When, stopping swinging handle, form now is as shown in Figure 6.Subsequently staff can be pushed away hand steered on dismountable beam 31 The work platformses to roll in orbit, until next place's enforcement place.Subsequently staff is again introduced in the work platformses Portion, by opposite direction rotation crank, declines fast assembling workbench 1 so as to which lower beam is contacted with tunnel inner wall.Again 4 Root brace 6 is placed on relevant position, limits the rotation of fast assembling workbench 1, hence into Construction in Preparatory Stage, can be by Aforesaid operations, carry out the operation of a new round.
