Abstract
The invention relates to a high and low gantry crane formed by a steel tube upright post for hoisting a long-span T beam. The high and low gantry crane consists of high-end upright posts, low-end upright posts and a load bearing beam. The high and low gantry crane is characterized in that: the high-end upright posts which are arranged on pier cover beams and are provided with two same arms are fixed on fixing bolts in the middle of two cover beams respectively; the low-end upright posts which are positioned under a bridge and are provided with two same arms are fixed with a reinforced concrete foundation on the ground through bolts respectively; the low-end upright posts with the two identical arms are spliced into trusses by using standard steel tubes, and a plurality of groups of steel tube trusses are assembled into the low-end upright posts serving as main arms; the top ends of the two same high-end upright posts and the two same low-end upright posts are provided with the load bearing beam and a crown block system; and the stability of the two same high-end upright posts and the two same low-end upright posts is ensured by wind-resistant ropes. The gantry crane has a light structure and high processing speed, is convenient to transport, reduces the labor intensity of aloft workers, shortens the splicing time to a great extent, realizes the function of full assembly which can only be realized by span pier gantry cranes, and saves 50 percent of materials compared with the span pier gantry cranes. The high and low gantry crane has the advantages of high efficiency, high safety and environment friendliness.
Description
Technical field
The present invention relates to during beam bridge builds, be used to finish stride greatly footpath T beam from ground to the bridge on the height gantry crane that adopts of vertical transport task, exactly be the height gantry crane that a kind of steel pipe post that is used for striding greatly footpath T beam lifting constitutes.
Background technology
Extensive propelling along with China's traffic infrastructure construction, the design of striding footpath, long distance, continuous bridge greatly progressively increases, and the addressing of these bridges, nearly all can be undeveloped in those traffic, the place deep in the mountains that road is rugged, road condition can not carry out big part goods and materials transportation fully, more can not bear design length at 40-50 rice, the transportation heavy burden of the large span T beam that weight is more than 100 ton, bear the unit in charge of construction of bridge construction in these locations, bearing the important task that the construction period is short, execution conditions are limited, construction task is heavy.Therefore, unit in charge of construction can only suit measures to local conditions because of ground, and it is beam prefabricated that T is carried out in addressing on the spot, finish T beam prefabricated after, how efficient, safety, carry out the lifting of beam slab to environmental protection, be a very crucial technical matters, and the gantry crane technology is to carry out the preferred option that the T beam lifts.
At present, in beam bridge was built, the lifting of T beam adopted the gantry crane technology very general, and this structure develops from " striding the pier gauntry crane ", can save some materials, thereby be subjected to the extensive employing of a lot of units in charge of construction; The early stage pillar construction form that occurs has: concrete column, omnipotent roofbolt column, tower crane type upright of frame etc.; The shortcoming of these pillar construction forms is, the engineering time is long, construction benefit is low, operating technique is unstable, need a large amount of personnel to carry out aloft work for a long time in the work progress, and safety misadventure takes place easily, is unfavorable for extensively promoting the use of.
Summary of the invention
The objective of the invention is to: the height gantry crane that provides a kind of steel pipe post that is used for striding greatly directly T beam lifting to constitute, this gantry crane structure is light, process velocity fast, be convenient to transportation, realization is transferred to the conception that the lifting equipment factory produces with the on-site consolidation time, reduce steeplejack's labour intensity, shorten assembling duration significantly, improve the work effect; High-end column is placed on the bent cap, realized striding the full width installation function that the pier gantry crane could be realized, also economize 50% material, speed of application is performed to the limit, reach the purpose of efficient, economy, safety, environmental protection than striding pier gantry crane joint.
The objective of the invention is to realize by the enforcement following technical proposals:
The height gantry crane that a kind of steel pipe post that is used for striding greatly directly T beam lifting constitutes, high and low end column, the load-bearing crossbeam identical by two product constitute, it is characterized in that: place the identical high-end column of two limbs on the bridge pier bent cap, constitute cube rod by fabricated universal steel members, be separately fixed on the middle bolt of rear end plate of two bent caps, the bottom point of connection of this cube rod is provided with the omnipotent bar working joint that can be assembled into the inclined-plane inverted triangle; Be positioned at the identical low side column of two limbs under the bridge, place on the ground in two bent cap outsides, reserve enough T beam rooms for promotion between its inboard and the bent cap outside, fix with bolt and ground-surface reinforced concrete foundation respectively, the low side column that two limbs are identical adopts the standard steel pipe to be assembled into truss respectively, organizes steel pipe truss more and is assembled into the low side column limb of deciding, in place by the crane direct mount, all form by bolted connection; The top of the high and low end column that two product are identical is installed load-bearing crossbeam, lifting rope respectively, do odds and ends winch and Overhead travelling crane system, is connected with high and low end column by " U-shaped " bolt; Wind resistance rope upper end is connected to the identical high and low end column top of two product, and the lower end is separately fixed at ground-surface appropriate location, the gantry crane outside.
Additional technical feature:
1), places the high-end column that constitutes cube rod on the bridge pier bent cap by fabricated universal steel members, in that being installed, this gantry crane inboard one collapses under the operating mode of 1-6 T beam of bridge, by the working joint on the fabricated universal steel members, the cube rod bottom is assembled into interior inclined-plane del column, interior inclined-plane and vertical pillars form 25.6-27.6 degree angle, with the position of 7-10 T beam transverse translation to 1-6 T beam.2), place the high-end column that constitutes cube rod on the bridge pier bent cap by fabricated universal steel members, after the two 7-10 T beams that collapse bridge of finishing the gantry crane outside lift, need collapse the 7-10 T beam transverse translation of bridge to the operating mode of 1-6 T beam with two, the cube rod that fabricated universal steel members constitutes need be fixed on the mounted T beam, by the working joint on the fabricated universal steel members, del inclined-plane, cube rod bottom column is assembled into outer oblique angle, outer inclined-plane and vertical pillars form 54-56 degree angle, install in the full width of finishing all T beams.
Advantage of the present invention is:
The height gantry crane that a kind of steel pipe post that is used for striding greatly directly T beam lifting constitutes, this gantry crane structure is light, process velocity fast, be convenient to transportation, the conception of lifting equipment factory is transferred to the on-site consolidation time in realization, reduce steeplejack's labour intensity, shorten assembling duration significantly, improve the work effect; High-end column is placed on the bent cap, realized striding the full width installation function that the pier gantry crane could be realized, also save 50% material, speed of application is performed to the limit, have the advantage of efficient, economy, safety, environmental protection than striding the pier gantry crane.
