Abstract
Disclosed are a stay cable device and a method for mounting stand columns of a gantry hoist. According to the stay cable device, two embedded parts are embedded in each position of the upstream face of the body of a dam, which corresponds to one of the stand columns, and the embedded parts are welded with a double-lug seat board; one end of each extending truss girder is connected with the corresponding upper embedded part, and the other end of the extending truss girder is connected with a corresponding stay cable; one end of each support rod is connected with the corresponding lower embedded part through a connecting pin shaft, and the other end of the support rod is connected with the corresponding extending truss girder to support the extending truss girder. According to the stay cable device and the method for mounting the stand columns of the gantry hoist, the extending truss girders are horizontally mounted on the upstream face of the dam, due to that fact the distance between the ends of the truss girders and the gantry hoist is larger than that between the ends of the truss girders and the upstream face of the dame, the fixing angle of the stay cables is relatively large, according to mechanics and geometric principles, the stay cables can provide relatively large force for the stand columns, further the tension for temporarily fixing the stand columns of the gantry hoist can be obtained.
Description
Technical field
The present invention relates to erecting device and method that a kind of large-sized gantry opens and closes gate leg, especially a kind of cable wind rope device and method that opens and closes the installation of gate leg for large-sized gantry.
Background technology
Gate and headstock gear are the requisite equipment of regulation and control streamflow in hydraulic structure.Gantry gate hoists equipment is mainly used in the opening and closing of gate.Gantry gate hoists can be along Dam axial-movement, and they complete after the keying of place's gate, is movable to another place and opens and closes operation again.Gantry gate hoists mainly by door frame, hoist and the mechanism such as walking and various device and other accessory structure form.Gantry gate hoists erection sequence mainly comprises: the installation of door machine track, traveling mechanism of the larger traveller and lower transverse beam is installed, door leg is assembled, and the lifting of door leg, crossbeam is installed, girder, end carriage lifting; And the installation of superstructure and other mechanism.
Along with the development of construction of hydropower plant, dam height constantly increases, thereby the increasing of door machine size, and door leg lengthens, and the width at dam crest of dam does not have much variations, has brought risk and difficulty to the installation of gantry gate hoists.
It is the important content that whole equipment is installed that door leg is installed.Door leg mounting method generally: door leg install adopt installation on ground, once lift by crane method in place.First door leg and top rail, middle cross beam are assembled into whole in dam crest section by accompanying drawing, then hang assembly top with crane, another mobile crane auxiliary body turning is afterwards by hoisted in position of large crane.At the upstream and downstream La Er road cable wind rope respectively of door leg, adjust the verticality of door leg, after door leg is adjusted to the right place by technical requirements, can carry out erection of main beam.
When large-scale door machine is installed, door leg center of gravity is higher, need be on monolith face when door leg is installed pre-buried cable wind rope draw ring face fixing so that connect with other parts.It is no problem that general downstream cable wind rope is arranged.And upstream side does not have place and the angle of pulling cable wind rope, if any door machine while installing, cable wind rope is pulled on checkdam, just 1000 meters of left and right of needs of cable wind rope, very uneconomical like this.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind ofly opens and closes for large-sized gantry the cable wind rope device and method that gate leg is installed, can be on narrow dam crest easily and safely temporary fixed large-sized gantry open and close gate leg.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of cable wind rope device that opens and closes the installation of gate leg for large-sized gantry, upstream face at dam is respectively embedded with two built-in fittings with door leg opposite position, on built-in fitting, be welded with ears panel seat plate, overhanging girder truss one end is connected with the built-in fitting that is positioned at top by connecting bearing pin, and the other end of overhanging girder truss is connected with cable wind rope;
One end of cramp bar is connected with the built-in fitting that is positioned at below by connecting bearing pin, and the other end of cramp bar is connected with overhanging girder truss, and overhanging girder truss is formed and supported.
Between described overhanging girder truss, also connect by transverse splicing truss welding.
Described cramp bar and the tie point of overhanging girder truss are positioned at from overhanging girder truss free end 2.3-2.7 rice soffit place.
Adopt above-mentioned device that a method for large-sized gantry keying gate leg is installed, comprise the following steps:
One, at the dam body upstream face of dam and each pre-buried two built-in fittings by arranging up and down of door leg opposite position;
Two, on built-in fitting, weld ears panel seat plate;
Three, overhanging girder truss one end is connected with the built-in fitting that is positioned at top by connecting bearing pin, cramp bar one end is connected with the built-in fitting that is positioned at below by connecting bearing pin, the other end of cramp bar is connected with overhanging girder truss, and overhanging girder truss is formed and supported;
Four, will between overhanging girder truss, connect with transverse splicing truss;
Five, one end of cable wind rope is connected with the free end of overhanging girder truss, the other end of cable wind rope is connected with door leg, and the opposite side of door leg is fixed on dam downstream face by cable wind rope;
By above-mentioned steps, large-sized gantry is opened and closed to gate leg temporary fixed.
When large-sized gantry opens and closes the installation of gate leg, because center of gravity is higher, be subject under surrounding environment Action of Wind pressure, producing larger overturning moment.In upstream, the close together of gantry gate hoists door leg and the guy draw ring position buried underground at dam crest, the pulling force of opposite house leg is little, a machine is installed and had unsafe hidden danger.The present invention is for solving large-scale door machine in the time that Hydropower Dam dam crest section is installed, the vertical technical barrier that has crank of door leg support.Thereby can guarantee the safety of large-scale door machine equipment installation process.
A kind of cable wind rope device and method that opens and closes the installation of gate leg for large-sized gantry provided by the invention, by being horizontally disposed with overhanging girder truss at dam upstream face.Because the termination of girder truss is large compared with dam facing upstream face distance apart from door frame, the fixed angle of cable wind rope is also just larger, and according to mechanics and geometrical principle, the value of thrust that cable wind rope offers a leg is also larger, thereby can meet the temporary fixed needed pulling force of door frame door leg.The door leg being undertaken by method of the present invention is installed, and due to the existence of overhanging trussed construction beam, makes the stretch-draw angle of cable wind rope large, and the pulling force that is subject to of door leg strengthens, and has ensured the safe and reliable of installation.Can save a large amount of cable wind ropes, good economy performance simultaneously.
