Abstract
The utility model provides a vertical assembly device of a steel cylinder spigot for large-caliber PCCP. An annular trough (2) is arranged on the external wall of an annular conical guide plate (1) from inside to outside; a platform bottom (6) is fixed on the bottom of the annular trough; a guide trough (3) is arranged on the annular trough (2) vertically downwards; the rear side of the lower part of a C-shaped self-adjustable centering block (4) is hinged on the platform bottom (6) on the lower part of the guide trough (3); the upper side of the rear part of the C-shaped self-adjustable centering block (4) is connected with the rear wall of the guide trough (3) by a pulling spring (8); the annular trough (2) is internally provided with a top block (5); and the self-adjustable centering block (4) and the top block (5) are uniformly distributed at interval along the ring. The C-shaped self-adjustable centering block (4) arranged on the circumference can carry out round positioning on the spigot so that the spigot and the cylinder can be centered automatically; the centering is exactly in place, the adhesion is tight, the assembly procedure is simplified, and the assembly quality and efficiency are improved.
Description
Technical field:
The utility model relates to the effective steel cylinder manufacturing technology of heavy caliber PCCP in the water conservancy projects, especially heavy caliber PCCP with vertical group of steel cylinder bell and spigot to device.
Background technology:
In the prior art, Prestressed concrete cylinder pipe is called for short PCCP, be widely used in large-scale water conservancy conveying engineering, wherein steel cylinder has sealing function and is connected socket ring and the effect of socket joint choma, steel cylinder adopts the weldering of wall thickness 1.5-2.0mm roll of steel plate to make, and next needs steel cylinder two-port welding socket and bellmouth.When the PCCP caliber greater than 3000mm, when length is 5-6M, because size is big and integral rigidity is not enough, under horizontal state, the cylindrical shell wall thickness is thinner, form is too soft, be difficult for being placed on the workbench, steel cylinder is difficult in the smooth and bell and spigot welding in two ends, even the construction of slinging because of there not being special hanger often to cause mouthful limit to be out of shape with hitting yet, can't realize the work of guaranteeing the quality smoothly, be prone to waste product.
Summary of the invention:
The purpose of this utility model provides a kind of contraposition that is used for heavy caliber PCCP steel cylinder welding bell and spigot, location, the fastening and group that supports to device, promptly heavy caliber PCCP with vertical group of steel cylinder bell and spigot to device.
Realize that the measure of the present utility model purpose comprises the inside open loop groove of annular deflector cone outer wall, at the bottom of the fixed station of annular groove bottom, convince groove on the annular groove vertically downward by patient analysis, on C shape self-regulated center bridge bottom rear side is hinged at the bottom of the guide groove lower stage, C shape self-regulated center bridge rear portion upside is by on the extension spring connection guide groove rear wall, settle jacking block in the annular groove, self-regulated center bridge and jacking block are evenly spaced apart along annular.
The utility model advantage: the C shape self-regulated center bridge of circumference carries out circle location with bell and spigot, but makes bell and spigot and cylindrical shell automatic aligning, and it is accurate to put in place, and closely sticks, and the simplification group is to operation, and the raising group is to quality and efficient.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment 1
Reference numeral comprises: deflector cone 1, and annular groove 2, guide groove 3, self-regulated center bridge 4, jacking block 5, at the bottom of the platform 6, hinge pin 7, extension spring 8, adhesive tape 9, air bag 10 takes blame for others 11, air inlet 12.
The specific embodiment:
Embodiment 1: the inside open loop groove 2 of annular deflector cone 1 outer wall, at the bottom of the annular groove 2 bottom fixed stations 6, convince groove 3 on the annular groove 2 vertically downward by patient analysis, C shape self-regulated center bridge 4 bottom rear sides are hinged at the bottom of guide groove 3 lower stage on 6, C shape self-regulated center bridge 4 rear portion upsides are by on extension spring 8 connection guide grooves 3 rear wall, settle jacking block 5 in the annular groove 2, self-regulated center bridge 4 is evenly spaced apart along annular with jacking block 5.Fixedly take blame for others 11 in the annular groove 2,11 openings of taking blame for others are outwards installed air bag 10, adhesive tape 9 and jacking block 5 successively, and jacking block 5 outer ends are circular-arc, and 11 rear portions of taking blame for others pick out air inlet 12.C shape self-regulated center bridge 4 top front ends are outstanding forward to be outer top section, and the bottom is outstanding forward to be lever segments.Self-regulated center bridge 4 is 12 groups of circumference.Self-regulated center bridge 4 can stretch under extension spring 8 effects.When the utility model embodiment uses, to hold earlier, the socket hoop descended deflector cone 1, be enclosed within annular groove 2 outer sections, utilize the deadweight of socket joint choma to push down self-regulated center bridge 4 downside lever segments, its upside section of top outward stretches out, withstand on and hold, on the socket ring inwall, make bell and spigot nature and deflector cone 1 concentric position, the deflector cone 1 of again steel cylinder being trapped, lower edge and inboard, oriented socket joint choma upper edge are lived by C shape self-regulated center bridge 4 outer top section upside loads, prevent to insert under the cylindrical shell dark, at this moment through air inlet 12 air inlets, air bag 10 is inflated outer top adhesive tape 9 and jacking blocks 5, and jacking block 5 outwards holds out against, cylindrical shell and socket joint choma are closely attached, outside electric welding location, the full weld weld seam is finished the welding of forming a team again, after steel cylinder after the welding and bell and spigot hang out, the withdrawal automatically under extension spring 8 effects of C shape self-regulated center bridge 4.Present embodiment guarantees that the making of heavy caliber PCCP steel cylinder meets every quality requirement of GB19685 regulation.
Among the utility model embodiment, the C shape self-regulated center bridge 4 of circumference carries out circle location with bell and spigot, but makes bell and spigot and cylindrical shell automatic aligning, and it is accurate to put in place, and closely sticks, and the simplification group is to operation, and the raising group is to quality and efficient.
