The utility model discloses can solve the problem of any board thickness, different pipe diameters, different kinds of pressure steel pipe stiffening ring installation location, can solve the installation stiffening ring again and cause the mother metal injury and cause and do over again, improve the work efficiency in man -hour.
Description
technical field:
The penstock stiffening ring that the utility model is applicable to penstock (straight tube, bend pipe, gradient tube) the stiffening ring installation exercise of any thickness of slab all kinds and caliber installs cranse device.
background technology:
At present, stiffening ring on pressure steel pipe of hydropower station installation is typically employed in spot welding triangle drift on steel pipe tube wall mother metal and, as interim frock, is cut off by triangle drift after stiffening ring installs, then with angle grinding machine polishing mother metal crator.This construction method has harmful effect to penstock mother metal performance, and crator of simultaneously polishing too increases artificial and auxiliary material use quantity, reduces penstock and makes work efficiency.
Also have in addition to adopt and constructed by penstock grout leaking hole mounting and positioning device, if stiffening ring does not arrange grout leaking hole, then this kind of mounting means cannot be constructed; This mounting means cannot carry out the installation exercise of bend pipe and transition penstock stiffening ring simultaneously, uses and has significant limitation.
utility model content:
The purpose of this utility model be can solve any thickness of slab to provide a kind of, different tube diameters, dissimilar penstock stiffening ring install location, can solve again and install stiffening ring and cause mother metal to injure and cause the problem of doing over again, the penstock stiffening ring improving work efficiency in man-hour installs cranse device.
The purpose of this utility model is achieved like this:
The utility model penstock stiffening ring installs cranse device, comprise at least two parallel to each other and with treat the cranse that operational pressure steel pipe radian mates, the connecting plate being contained in cranse two end respectively, to be positioned between two connecting plates parallel equidistant from the multiple location-plates be contained on cranse, leveling board is equipped with respectively in multiple location-plate homonymy termination, connecting plate there is multiple connecting hole, connecting hole is equipped with bolt.
(be advisable for 8-12) after pressing force outer diameter of steel pipes size carries out decile, by decile arc make same radian, etc. the utility model cranse device of chord length; Penstock outer wall stiffening ring position point is installed on by after the assembling of each cranse device, by the bolt that each cranse device connecting plate is arranged, it is fastening, cranse and penstock outer wall are fitted, stuck, carry out spot welding after then whole circle stiffening ring is installed and fix.After stiffening ring installation, unscrew each cranse device bolt, after taking off each cranse device, recycling.
The utility model apparatus structure dexterity is convenient, and weight is slim and graceful, effectively can solve when installing stiffening ring and cause mother metal injure to penstock outer wall temporary weld location-plate, has evaded the secondary that repairing penstock outer wall mother metal carries out and has done over again.The utility model device cranse pressing force outer wall of steel pipe diameter carries out decile making simultaneously, and cranse radian and outer wall of steel pipe are fitted completely, and cranse positioning precision high energy ensures stiffening ring installation quality.Cost of manufacture is low, and use safety is efficient, can reuse.Efficiently solve penstock bend pipe, gradient tube cannot adopt positioning tool to carry out installing the situation of stiffening ring, also solve and rely on conventional spot-welding equipment to assist the technique that stiffening ring damages mother metal is installed.
After the utility model is on probation, than adopting spot-welding equipment, the work efficiency that stiffening ring saves 3 times is installed, material economy 90%, artificial saving 50% consuming time; Than the mounting means adopting grout leaking hole mounting and positioning device, stiffening ring is installed and saves 50% work efficiency, artificial saving 30% consuming time.

detailed description of the invention:
See Fig. 1 ~ Fig. 4, the present embodiment penstock stiffening ring installs cranse device, comprise two parallel to each other and with treat cranse 1 that operational pressure steel pipe radian mates, be contained in the connecting plate 2 of cranse two end respectively, be positioned between two connecting plates parallel equidistant from the multiple location-plates 3 be contained on cranse.Multiple location-plate homonymy termination is equipped with leveling board 4 respectively.Connecting plate there is multiple connecting hole 5.Bolt 5 connecting hole is equipped with.
Above-mentioned cranse to be shaped pre-bending by thin band iron, and be main stressed and connecting elements, pre-bending radian is equal with outer diameter of steel pipes, and pressing force outer diameter of steel pipes makes after carrying out decile, and made cranse number connects equal with penstock outer wall girth afterwards.
Above-mentioned leveling board is welded on cranse location-plate, for leveling the levelness of stiffening ring is installed, keep all stiffening rings to be on a datum level.
Above-mentioned location-plate is welded on cranse, for supporting stiffening ring.
Above-mentioned connecting plate is welded in cranse two ends respectively, makes adjacent cranse firmly can connect into entirety by bolt.
See Fig. 5, Fig. 6, if secondary pressure steel pipe 6 outer diameter 6530mm, thickness of slab δ=30mm, tube coupling height 3000mm, arrange 3 layers of stiffening ring 7: ground floor stiffening ring center to tube coupling upper port is 500mm, second layer stiffening ring center to tube coupling upper port is 1500mm, and third layer stiffening ring center to tube coupling upper port is 2500mm.6 the utility model cranse devices 8 are adopted to assemble.
Penstock stiffening ring installs that cranse device makes, uses, program of removing is as follows:
(1) penstock stiffening ring installs the making of cranse device: utilize band iron, steel plate to process 6 penstock stiffening rings by accompanying drawing 1, Fig. 2 and install cranse devices, should be equal to or slightly less than penstock outer wall girth after each cranse girth carries out general assembly, but radian must be equal.The maximum piece weight 23.8Kg of single cranse device, all gross weight 142.8Kg after assembling.
(2) penstock stiffening ring installs the installation of cranse device: after penstock 6 longitudinal seam welding, tune have been justified, by the setting-out of stiffening ring 7 distributing line on penstock outer wall, then will be that under stiffening ring is installed, contact surface is benchmark with leveling board after each cranse general assembly, accurate adjustment penstock stiffening ring installs cranse device, make the penstock stiffening ring leveling board installed on cranse device all be positioned at stiffening ring and install lower contact surface center, penstock stiffening ring is installed after fastening pressure pipe stiffener ring installs all connecting bolts of cranse device and is installed stiffening ring.
(3) penstock stiffening ring installs the dismounting of cranse device: after stiffening ring spot welding completes, unscrew the bolt on cranse, cranse and penstock outer wall are come off, recycling.
