The present embodiment, first by three folding pillar designs, be " multi-deck extension folds pillar 8 ", be that the folding pillar of every joint is comprised of multi-layer hydraulic telescoping cylinder, as a telescopic folding pillar has M (M=3-5) joint, every joint telescopic folding pillar has N (N=3-5) layer hydraulically extensible cylinder, every joint hydraulically extensible cylinder is long is L (L=6-12 rice), " multi-deck extension folds pillar 8 " trail after its total length be M * N * L, as shown in 8 (c) in Fig. 3.In addition, be connected collapsible between every two joint telescopic folding pillars by hinge, when folding pillar stretches, straight with alignment pin 29 pins between two joint telescopic folding pillars, folder function is completed by the little folding cylinder 13 of power, as shown in Figure 4.
Secondly, around bridge cabin 6 on flatcar 44, be provided with one group of multi-deck extension vertical hydraulic cylinder 7 jacking top board 9, by top board 9, through very heavy suspension ring 32, hang Sheng Qiao cabin 6 again, multi-deck extension vertical hydraulic cylinder 7 can be since 0 meter of jacking bridge cabin 6, when bridge cabin 6 is raised to M joint telescopic folding pillar 8 and stretches, just start to be worked by the multi-layer hydraulic telescoping cylinder relay of the folding pillar of every joint, 6 jackings of bridge cabin are arrived to specified altitude assignment, because be that hydraulic lifting is firmly minimum, so structure is light, N layer hydraulically extensible cylinder can be worked simultaneously, so also can improve N * M doubly by rising cabin speed.
In addition, the scalable crane span structure of link-type of bridge cabin 6 interior installations, the clamping cylinder 17 that its front end is installed can be controlled the folding of clamp jaw 18, and whole crane span structure tightens up at ordinary times, and pontic is all contracted in bridge cabin.
During use: see Fig. 1, Fig. 2, Fig. 3, it is the utility model " hydraulic relay jacking type tall-building fire fighting bridge " theory structure schematic diagram, three root multi-layer telescopic folding pillars are placed in respectively on flatcar 1, flatcar 22, flatcar 33, elevator cabin, bridge cabin 6, upright multi-deck extension hydraulic cylinder 7 are placed on flatcar 44, arrive behind the scene of a fire, flatcar 1, flatcar 22, flatcar 33 select rational position in place, and flatcar 44 is positioned in the middle of three pillar cars.
As 8 (a) in Fig. 1, 7 (a) are respectively the folding pillar 8 of multi-deck extension and the original state figure of upright multi-deck extension hydraulic cylinder 7 before work, during work, first starting auto-programming is connected the top of three root multi-layer telescopic folding pillars 8 with top board 9, then start upright multi-deck extension hydraulic cylinder 7, by upright multi-deck extension hydraulic cylinder 7, heading on top board 9 upwards rises, when top board 9 upwards rises, very heavy suspension ring 32 on top board 9 hang Sheng Qiao cabin 6 and together rise, now, elevator case 5 is fixed on flatcar 44 by elevator cabin anchoring pin 24, elevator cabin lifting rope barrel 20 loosens elevator cabin lifting cable 22 by automatic control program, meanwhile, the three root multi-layer telescopic folding pillars 8 that are connected with top board 9 also stretch and rise thereupon.
When peak is arrived in the jacking always of upright multi-deck extension hydraulic cylinder 7,7 (b) as shown in Figure 2, because respectively saving hydraulic cylinder, multilayer folding pillar to instruction pressurization, do not rise, so the folding pillar 10,11,12 of every joint is all the shortest, under the booster action of folding cylinder 13 that folds pillar, just in time the folding pillar of several joints is pulled into straight line, as the state of 8 (b) in Fig. 2.
Using fold in pillar, save 11 and folding pillar on save structure between 12 as example is as explanation, now, in folding pillar, save 11 with folding pillar on save the positional cylinder 33 that piston alignment pin 29 between 12 saves 11 final stage piston rod 37 tops in folding pillar and eject by hydraulic power, be pressed in the pin-and-hole of locating piece 28 of the outer shell 39 that saves 12 on folding pillar, visible Fig. 4, in like manner under folding pillar, save 10 with folding pillar in to save 11 be also so, thereby right cylinder that will folding pillar being changed into multilayer Multi-section retractable.
Start bridge cabin 6 and continue climb procedure, each layer of hydraulically extensible cylinder in the folding pillar of each joint ejects and rises to specified altitude assignment step by step, as shown in 8 (c) in Fig. 3, the retractor device 14 that arrives specified altitude assignment back link formula crane span structure starts, crane span structure 15 " release " is arrived to assigned address, at this moment, bridge front end clamp jaw 18 is in level, through scene of a fire window, clamping cylinder 17 starts clamp jaw 18 is become vertically windowsill 19 is clamped by level, thereby formed the catwalk to the scene of a fire by bridge cabin 6, fire fighter or indicator of trapped personnel can be come in and gone out through this bridge.
In order to facilitate ground contact, elevator cabin anchoring pin 24 is opened, by lifting reel 20, tighten up cable 22, elevator case 5 can be raised to and need position.
Elevator lifting cable 22 is walked around the pulley 23 that is distributed in 6 four jiaos, bridge cabin, one end is passed down through after the cable guide hole 25 of elevator case 5, walking around directive wheel 21 is connected with rope barrel 20, this structure can make elevator lifting cable 22 when anchoring pin 24 is not yet opened and reel 20 is tightened up, play two effects, the one, as the hawser in bridge cabin 6, guarantee that bridge cabin 6 does not turn, the 2nd, when crane span structure 15 is opened, can keep pontic balance.
The operating process of a kind of hydraulic relay jacking type of the utility model tall-building fire fighting bridge is operated conversely, can recover the reset condition of armamentarium.
Directly supplying water in Ke You ground, water for fire extinguishing source, also can on pillar, install and adhere to water pipe water supply.
Whole power of the present utility model provides power source by each flatcar.
