Technical field
The utility model relates to a kind of floor rail type driving that is used for bridge construction, refers more particularly to the floor rail type gauntry crane that promotes the super-tonnage bridge.
Background technology
At present, in field of bridge construction,, mainly adopt following three kinds of arrangement and method for construction for the whole case beam of large-tonnage is promoted to the dress beam operation that bridge floor carries out fortune frame on the beam:
First kind of scheme is for filling the bridge construction sidewalk, and girder carrier runs to bridge floor along last bridge sidewalk behind the beam prefabricated on-the-spot dress beam of case, again along bridge floor carrying case beam.This construction method is applicable to that fortune beam initial point is the roadbed section, and the roadbed height is not too high, and the engineering of single width bridge case beam fortune frame construction, and operating efficiency is lower relatively.
Second kind of scheme adopts the crane barge shipment for building harbour, is applicable to and adopts crane barge to carry out case beam lifting operation in deepwater regions, and beach district, water level be shallow, receive the fluctuation tide to influence inapplicable this scheme of big construction area.
The third scheme adopts the gauntry crane of large span that the case beam is promoted upward bridge from ground for special-purpose bale handle station is set.This scheme cost of equipment has high input, but supporting operation efficient is high, technology is advanced, and fortune beam initial point can be any section (being not necessarily roadbed) of bridge, also helps transportation rack device on assembling and the disintegration bridge.
For the whole case beam of large-tonnage is promoted to the dress beam operation that bridge floor carries out fortune frame on the beam; At present both at home and abroad in the lifting of the whole case beam of the large-tonnage of high speed railway, express highway in the bridge construction maximum tonnage be 900 tons, also do not have equipment can 1500t/50m case beam be promoted to the dress beam operation that bridge floor carries out girder carrier from ground.
Summary of the invention
The utility model technical matters to be solved is the technical deficiency to above-mentioned existence, and a kind of low cost of manufacture is provided, and it is big to promote power, is used to promote the floor rail type gauntry crane of 1500t/50m large-tonnage prefabricated case beam.
For solving the problems of the technologies described above, the technical scheme of the utility model is following: the floor rail type gauntry crane includes girder and the supporting leg that is used to support girder; Girder is provided with the lifting appliance that can slide; It is characterized in that: captive joint with girder in described supporting leg top, the bottom is connected with walking carriage, and hydraulic ram is equipped with in the walking carriage bottom; Hydraulic ram can be lowered and withstand ground, carries jointly with wheel.
In such scheme, described ground rail is fixed on the track girder, and track girder adopts ferro-concrete to pour into trapezoidal continuous beam, and the bored pile basis is adopted in the track girder bottom, and is provided with cushion cap.
In such scheme, described lifting appliance includes hanging beam purlin car and lifting motor, and hanging beam purlin car can slide on slide rail, and the lifting motor is installed in suspension bracket purlin roof, and the power of lifting motor is greater than 45kw.
In such scheme; Described supporting leg is the truss structure of falling the rectangular pyramid, and the supporting leg main structure is made up of box type rod piece, connects through strengthening flower stand between the rod member; Is connected through pin between the bottom of supporting leg and the walking carriage, the employing bolt is connected between the top of supporting leg and the girder.
In such scheme; In the middle of described hydraulic ram was arranged in the walking carriage, hydraulic ram was the large-tonnage support cylinder, can be when lifting large-tonnage prefabricated case beam and the wheel of walking carriage carry the load of lifting jointly; When the hanging beam operation of original place; The hydraulic ram that is positioned at walking carriage is put down and is supported on the ground, so that extra support to be provided, guarantees stability and the axial force of the supports of sharing wheel longitudinally.
When playing the box beam, box girder integral level lifting during perfect condition, each Heave Here stress equalization is consistent, but receives factor affecting such as the derricking gear operation is not exclusively synchronous, the hanger structure size is not quite identical, is difficult to reach above-mentioned perfect condition.In order not make case beam, device structure parts therefore cause unbalance stress even destruction, when adopting two perhaps more the utility model floor rail type gauntry crane combinations to use, the lifting appliance of two gauntrys crane is distributed as bikini; Promptly the lifting appliance of a gauntry crane is movable suspender; Suspender two parts up and down connects through central pin shaft, and two groups of suspension centre equivalences are converted into a suspension centre, and the suspender of another gauntry crane is a fixed spreader; Two groups of suspenders are independent respectively, form two suspension centres.Through three suspension centre systems, guarantee the stress equalization and the level lifting of lifting.
The beneficial effect of the utility model is: low cost of manufacture, and easy to operate, high efficiency, safety and reliability are high, use the combination of many playscripts with stage directions utility model device, and it is big to promote power, can promote 1500t/50m large-tonnage prefabricated case beam.
