Abstract
The invention relates to a method for invertedly machining a gate flap panel of a steel arch-gate. The method comprises the following steps of: firstly excavating a gate holding base pit according to the appearance characteristics of a structure member, supporting a beam seat on a concrete base by fixed support hinges and connecting the fixed support hinges, wherein the two fixed support hinges are required to be concentric, a movable support hinge is connected with the fixed support hinge by a support hinge shaft, the movable support hinge is connected with a support arm, and the support arm is connected with a gate flap; placing a plain miller at the outer side of the gate flap panel of the steel arch-gate; machining a waterstop surface of the gate flap panel of the steel arch-gate by the milling of the plain miller; and after a station is machined, enabling the gate flap to synchronously and rotatably lift along a support hinge shaft, and then machining the next station.
Description
Technical field
The present invention is applicable to the whole processing of Hydraulic Metal steel arch-gate gate flap panel, also is applicable to large-scale nonstandard steel work cambered surface processing simultaneously.
Background technology
The down-the-hole steel arch-gate radius of Hydraulic Metal is mostly more than 10m, and the area of gate panel is also at width * highly=more than 5m * 7m.
End water seal water, both sides side sealing water shutoff and top sealing water shutoff are adopted in the down-the-hole steel arch-gate gate flap of Hydraulic Metal and the water shutoff of gate hole respectively, form the airtight water-stopping system of " " shape.
End water watertight rubber is installed on the root edge of gate flap, and the weight compression end water rubber by gate flap makes that the end water seal water is tight.Side sealing watertight rubber is installed in the lateral edges outside of steel arch-gate gate flap, and the stainless steel (stainless steel sealing face carries out finished) of watertight rubber and gate hole side sealing embedded part has the 5mm decrement, makes that the pressing of water shutoff bonding surface is tight, and water shutoff is tight.
Top sealing watertight rubber is installed on the lintel of gate hole embedded part, the panel of watertight rubber and steel arch-gate gate flap (down having approximately from the gate top in the sealing zone of 2m to 3m) has the 5mm decrement, because the Segment gate gate flap belongs to welded construction, welding contraction distortion appears in metal construction in welding process, cause the cylindricity of arc surface to occur than mistake, make the panel decrement of watertight rubber and steel arch-gate gate flap produce inhomogeneous, under the effect of high water head, cause water shutoff not tight, infiltration, drainage occur, tend to surpass the requirement of standard.
Along with the instructions for use of modern Hydraulic Metal gate is more and more higher, the cambered surface sealing of its steel arch-gate gate flap part must be processed the required precision that just can meet the requirements of cylindricity, roughness.Guarantee that by this gate water shutoff is tight, stable working.
From processing market, there is not large-scale steel arch-gate load-bearing to exceed hundred tons cylindrical process equipment as yet.Rely on single pure cylindrical process equipment can't finish the processing of steel arch-gate panel sealing part.
Summary of the invention
This construction technology is inverted (the top panel sealing part of gate flap below, root edge is inverted up) with steel arch-gate by the gate flap duty, in gate is placed working pit, make gate flap along a hinge rotation and lifting, finish cambered surface processing by the milling of unit head.
Adopt the method for Milling Process, Milling Process can only be the plane, forms broken line with a plurality of facets, is similar to arc surface, and the facet polygon is more little many more, gets over and becomes to approaching circular arc.More than 10m, if each processing plane height has 80mm, the radius error of its circularity only below 0.008mm, is far superior to the requirement of Hydraulic Metal water shutoff to large-scale Segment gate radius mostly.
This technology is inverted assembling by the gate duty and is connected: at first lay foundation ditch according to structural member resemblance excavation gate, and will fix a hinged bearing beam seat on concrete foundation and be connected and fixed a hinge, two fixing hinges require with one heart, movable hinge is hinged with fixing by a hinge, and movable hinge is connected with support arm; Support arm is connected with the gate flap panel again; Then plain mille is placed steel arch-gate gate flap panels outside, finish the processing of steel arch-gate gate flap panel by the milling of plain mille; After processing a station, buttress that the bottom of the openend by the both sides support arm is provided with and fine setting jack are adjusted the gate flap lifting position, and gate flap is risen along a hinge rotation, carry out the processing of next station; After the fine setting jack reaches the limit of stroke, with steel work gate flap is supported temporarily, adjust the fine setting jack to the limit inferior travel position, extract the conciliation location axle pin on the buttress, reconciling location axle pin makes up with the next locating hole of reconciling, the elevation of buttress is raise, descend the processing of several stations then; Repeat gate flap to be supported temporarily, adjust and reconcile location axle pin and the combination of reconciling locating hole, the elevation of buttress is raise gradually, until the processing of finishing gate flap panel sealing face with steel work.
Use this technical operation to have the following advantages: 1. personnel work on the ground, easy operating, and safety is guaranteed; 2. lathe bed is constant, and Working position is constant; Prop up hinge and fix, the measurement hierarchy of control more easily is set, be easy to control and check crudy; 3. investment cost is low, only excavates working pit, the firm concrete foundation that a fixing hinge place is provided with.
