Description
Technical field
The present invention relates to a kind of pipeline spreader, especially a kind of can the pipeline spreader of horizontal displacement, belong to pipeline spreader design field.
Background technology
For main steam line and the reheating pipeline of million kilowatt ultra supercritical thermal power generation unit, running temperature, more than 600 DEG C, is mounted opposite state, and during operation, the horizontal displacement of hundreds of millimeter can occur a suspension centre of pipeline.In order to avoid excessive deflection occurs the suspension rod hanging this kind of pipeline, bring disadvantageous internal stress to change to pipeline, need to allow the point of suspension equidirectional displacement of place along with pipeline of taking root of hanging pipeline suspension rod.Adopt the boatswain chair of top tape cylinder, allow the equidirectional displacement of cylinder scrolling realization and pipeline suspension point in horizontal vallecular cavity; When root rollers roll resistance is larger, suspension rod still can be caused to occur large deflection.For this reason, engineering circles adopts ball line slideway auxiliary to replace cylinder to realize the low resistance of root parallel motion, but this structure has following shortcoming:
(1) main steam line of million kilowatt ultra supercritical thermal power generation unit and reheating pipeline are all the alloy pipes of super large caliber super thick degree, the performance load of the suspension and support of these pipelines is very large, but be point cantact between the ball adopted in ball line slideway and guide groove, load-carrying capacity is little, is not thus suitable in the hanging mechanism of heavy-load pipeline.
(2) antifriction-bearing box hanger plate structure adopts with building girder steel and is welded to connect, even if the adjustment of ball line slideway is reached level requirement, but after the carrying of welding deformation, girder steel, flexure deformation all can make the guide rail of level-off occur new horizontal deflection, but lacks the mechanism adjusted again in structure.Also cannot adjust again through one section of horizontal deflection found after running.
(3) antifriction-bearing box hanger plate structure directly cannot measure the levelness of the guide-track groove of ball movement, can bring deviation to the accuracy of installing.
(4) guide-track groove of antifriction-bearing box hanger plate structure has roomy gap with extraneous, dirt exclusion capabilities is poor, at the dust that heat power plant boiler produces, guide-track groove and ball is very easily polluted in acidic gas environment, cannot often wiping safeguard again, by making the resistance of movement rise rapidly, lose the radical function of the low moving resistance of ball line slideway auxiliary.
Summary of the invention
Object of the present invention is exactly for above-mentioned the deficiencies in the prior art, provide a kind of rational in infrastructure simple, manufacture easily, load-carrying capacity is strong, be convenient to measure position and adjust can the pipeline spreader of horizontal displacement.
The object of the present invention is achieved like this, a kind of pipeline spreader of roller line slideway parallel motion, comprise carrying girder steel, loading plate, suspension rod, it is characterized in that: be provided with a shape carrier, top guide rail, roller line slideway block, the bottom surface, corner of described carrying girder steel is provided with adjustable sizing block, and the side plate of carrying girder steel is provided with flipper guide and scale, and top guide rail is arranged on the end face of carrying girder steel, roller line slideway block is arranged on the guide rail of top, and door shape carrier is arranged on roller line slideway block; Described door shape carrier is made up of top board and biside plate, top board bolt is connected with roller line slideway block, and the inner side of side plate is provided with sliding shoe, and the side plate lower end of side plate is provided with the loading plate of band circular hole, the upper end of described suspension rod is provided with screw thread, and the upper end of suspension rod to spin nut through the circular hole on loading plate.
Dust boot is provided with above the top guide rail at described door shape carrier two ends.
The sliding shoe height being arranged on side plate interior sides is corresponding with the flipper guide height on carrying girder steel side plate, has 1-2 millimeter gap between sliding shoe and flipper guide.
Described dust boot is rigid telescopic formula guide rail protection cover.
The present invention rational in infrastructure simple, manufacture easy, easy to use, overcome the deficiencies in the prior art, produce following positive technique effect:
(1) adopt cylindrical bearing line slideway block and the straight guide rail of high hardness secondary as the low frictional resistance of suspender parallel motion, the coefficient of friction resistance is less than 0.01; Load-carrying capacity reaches more than ten times of ball line slideway auxiliary, can reach the bearing capacity of 100 tons.
(2) bottom carrying girder steel corner is equipped with adjustable sizing block, and high hardness is straight, and guide rail is placed on the end face carrying girder steel, directly can be placed on the guide rail of top by high-accuracy water level and carry out horizontal degree measurement and adjustment.
The side plate of carrying girder steel is provided with smooth flipper guide and graduated scale, the sliding shoe matched with flipper guide has been installed in the position being buckled in the side plate interior sides opposite side guide plate of the door shape carrier on cylindrical bearing line slideway block, guiding during pipeline spreader parallel motion is defined between flipper guide and sliding shoe, sliding shoe can do level attitude along flipper guide and move, and can read the position of pipeline spreader movement from scale.
(3) lower end of door shape carrier side plate is fixedly connected with the pipeline suspension loading plate of Intermediate Gray circular hole, and the upper end of the suspension rod of hanging pipeline is provided with screw thread, and it tangles pipeline through after the circular hole in loading plate after nut engagement, realizes the transmission of pipe load.Twist the height that nut just can change pipeline hanging.The occasion that it is specially adapted to pipeline center and bulk between girder steel of taking root is little, in turn saves the union pieces such as the high turnbuckle of manufacturing cost and U-nut.
(4) push up above guide rail, the two ends of door shape carrier have installed dust boot additional, dust boot is rigid telescopic formula guide rail protection cover, and actv. protects guide rail from the pollution of dust, acidic gas and corrosion; Examination and maintenance can be carried out to roller line slideway block and top guide rail etc. after removing dust boot.
