Detailed description of the invention
By technological means and effect that the present invention by reach predetermined goal of the invention taked being expanded on further, below in conjunction with attached Figure and preferred embodiment, to the bridge structure hanging method proposed according to the present invention and the tool of bridge hoisting mechanism skid Body embodiment and operation principle are described in detail.
Bridge structure hanging method provided by the present invention, as it is shown in figure 1, use weight not affect the bridge of bridge stability Beam hoisting mechanism longeron 5 along bridge structure lower end is exercised and is lifted, and comprises the steps:
A. bridge end bay is lifted;
B. move to described bridge hoisting mechanism in the bridge structure lower end at end bay edge, on longeron, to be fixed in bridge On;
C. in being lifted by bridge hoisting mechanism, front 1/3rd of span to front 1/2nd internodes, and use interim Connect and end bay and middle span are rigidly connected, after often having lifted an internode, by bridge hoisting mechanism along bridge structure lower end Longeron moves forward to next internode lifting position, then bridge hoisting mechanism is fixed on bridge, starts to lift next Internode;
D. bridge hoisting mechanism is moved rearwardly into end bay end, and is fixed on bridge, by bridge hoisting machine Structure lifting steel construction button tower and cable;
F. bridge hoisting mechanism longeron along bridge structure lower end is moved forward, use the mode of step C to continue lifting Middle span remainder.
For bridge hoisting mechanism, the present embodiment have employed the pedrail crane laying down track wheel, and passes through skid Make the pedrail crane laying down track wheel longeron 5 along bridge structure lower end exercise to lift.Concrete lifting step includes:
A. construct the incipient stage, use pedrail crane on river bank, bridge end bay to be lifted;
B1., pedrail crane unloads track wheel consolidate as bridge hoisting mechanism, the pedrail crane that track wheel will be laid down It is scheduled on skid;
B. bridge hoisting mechanism is moved in the bridge structure lower end at end bay edge on longeron 5 by carriage, by it It is fixed on bridge;
C. in being lifted by bridge hoisting mechanism, front 1/3rd of span to front 1/2nd internodes, and use interim Connect and end bay and middle span are rigidly connected: after often having lifted an internode, by bridge hoisting mechanism along bridge structure lower end Longeron moves forward to next internode lifting position, then bridge hoisting mechanism is fixed on bridge, starts to lift next Internode;
D. bridge hoisting mechanism will be moved rearwardly into end bay end by carriage, and is fixed on bridge, By bridge hoisting mechanism lifting steel construction button tower and cable;
F. by carriage, bridge hoisting mechanism longeron along bridge structure lower end is moved forward, use step C Mode continues span remainder in lifting.
Bridge structure hanging method provided by the present invention is the bridge hoisting machine using weight not affect bridge stability Structure, it is exercised along longeron 5 in bridge structure lower end and lifts.The special revolution loop wheel machine of employing of the prior art is in purlin Top of the trellis, will exercise and lift on the upper end longeron 6 of bridge structure.The work that present invention reduces hoisting mechanism is high Degree, reduces the vibrations in bridge hoisting stage so that hoisting process is more safe and reliable simultaneously.Common pedrail crane can be used Hung by carriage sliding on longeron 5 in bridge structure lower end, arrival operating position after being laid down track wheel Dress, thus greatly reduce steel truss bridge hoisting cost, shorten total cycle that bridge manufactures.
The skid used in the present embodiment is as it is shown on figure 3, include: hoisting mechanism load bearing seat 1, drive mechanism, removable Formula retention mechanism, position-limit mechanism.Wherein, bridge hoisting mechanism is fixed on hoisting mechanism load bearing seat 1 by position-limit mechanism, lifting Mechanism's load bearing seat 1 is by being connected with drive mechanism with drive mechanism interface 4, and hoisting mechanism load bearing seat 1 is by removable fastening machine Structure is removably fixed with longeron 5 in bridge structure lower end.
Position-limit mechanism is multiple, and each position-limit mechanism is respectively arranged in the surrounding of hoisting mechanism load bearing seat 1, wherein, at least The position-limit mechanism in a direction is had to be arranged on hoisting mechanism load bearing seat 1 in the way of removable or adjustable stroke.So as bridge Hoisting mechanism is installed.In position-limit mechanism, it is in the front limit mechanism 2-2 of hoisting mechanism load bearing seat 1 front portion, is in hoisting mechanism and holds Carry the rear position-limit mechanism 2-3 at seat 1 rear portion, respectively in the structure with bridge hoisting actuator base front and back ends tabling, the present embodiment In, the position-limit mechanism being in hoisting mechanism load bearing seat 1 front end is arranged at hoisting mechanism load bearing seat 1 in the way of adjustable stroke On.After bridge hoisting mechanism is seated on hoisting mechanism load bearing seat 1, lateral Displacement mechanism 2-1 coordinates hoisting mechanism load bearing seat 1 torr Live bridge hoisting mechanism, prevent it from lateral shift occurring;Rear position-limit mechanism 2-3 blocks the rear end of bridge hoisting actuator base, anti- Only it offsets upwards and backwards;Front limit mechanism 2-3 is by regulating its stroke so that it is before blocking bridge hoisting actuator base End, prevents it forward and offsets up, making bridge hoisting mechanism fix with skid.
Removable retention mechanism includes two groups, and two groups of removable retention mechanisms are respectively arranged in hoisting mechanism load bearing seat 1 Lower section, is particularly located at the position corresponding with the two of bridge structure lower end middle longerons 5.Often organize removable retention mechanism for many Set, often overlaps removable retention mechanism and includes: top board 3-1, lower platen 3-3, connecting bolt 3-2.Top board 3-1 is arranged at lifting On mechanism's load bearing seat 1, lower platen 3-3 is in the lower section of longeron 5 in bridge structure lower end, and lower platen 3-3 passes through connecting bolt 3-2 Removably it is fastenedly connected with top board 3-1.Between hoisting mechanism load bearing seat and bridge, servoboard is set.Drive mechanism is liquid Pressure drive mechanism, is mainly acted on by two oil cylinders, it is ensured that equipment can slide along fixed-direction, prevents slipping simultaneously In shift phenomenon.
The operation principle of skid is: by position-limit mechanism, bridge hoisting mechanism is fixed on hoisting mechanism load bearing seat 1 On, make longeron 5 sliding along bridge structure lower end of bridge hoisting mechanism by drive mechanism by hoisting mechanism load bearing seat 1, when After arriving operating position, reduced the spacing of top board 3-1 and lower platen 3-3 by connecting bolt 3-2, equipment is locked with bridge Tightly, position.After having lifted an internode, unclamp connecting bolt 3-2, but do not move out, make in slipping lower platen 3-3 still On the one hand being connected with connecting bolt 3-2, its purpose is: in order to avoid there are special circumstances, prevent skid and crane this Entirety there occurs overall offset, guarantees safe production;On the other hand, reduce in hoisting process, the set time of skid.
It should be noted last that, above detailed description of the invention only in order to technical scheme to be described and unrestricted, Although the present invention being described in detail with reference to example, it will be understood by those within the art that, can be to the present invention Technical scheme modify or equivalent, without deviating from the spirit and scope of technical solution of the present invention, it all should be contained In the middle of scope of the presently claimed invention.
