Description
Technical field
The utility model relates to the tube-making technology field, specifically refers to the implement device of locating with height such as steel pipe Down Highways when a kind of Prewelding machine steel pipe is carried.
Background technology
Along with the popularization that the development and the steel pipe of oil pipeline industry are used in building trade, tubulation is flourish in China.Tubulation industry is also more and more high to the requirement of tubulation apparatus, wherein requires wall thickness more and more big (up 80mm), specification limit wide (Ф 324 ~ Ф 1626mm), the changes in material scope of steel pipe big in (by structural steel to stainless steel).Tubulation apparatus will satisfy these and require to have certain degree of difficulty in the design, certain structures, mode, and handling according to original theory is impossible realize, must change original thinking, takes new theory, uses a cover new construction solve problem.
The charging transport of steel pipe linking machine comprises that separate type rollgang and two mechanisms of chain drive bobbin ejector form.The entry position that steel pipe runs to machine is to lean on the rotation of rollgang roller to carry; Steel pipe entering main frame carries out joint close and pushes main frame by force by the chain drive bobbin ejector.The passive rotation of rollgang when the chain drive bobbin ejector promotes steel pipe only works to hold up steel pipe.Before and after the main frame, steel pipe rollgang and chain drive bobbin ejector are arranged together, and adopting the separate type rollgang is exactly in order to reserve running space for the chain drive bobbin ejector.
The size of the size decision ejector sleeve power of joint close power, the stress and the physical dimension of the application point decision bobbin ejector backing roll of ejector sleeve power, ejector sleeve power.Bobbin ejector stressed big, application point is high, the size of bobbin ejector is just big, the separating distance of rollgang just needs big; On the other hand, the diameter dimension of steel pipe is big, and the separating distance of rollgang can be big; The diameter dimension of steel pipe is little, and the separating distance of rollgang must be little; When the caliber scope and the wall thickness range of steel pipe reaches certain scope, use conventional locate mode, just satisfied not having required.
The conventional locate mode that steel pipe is carried is the height of steel pipe at the V-type roller-way, and the V-type roller-way before linking machine separates, and the spacing of two separating roller way is fixed.Its shortcoming is, 1. the Down Highway of big caliber steel pipe is high, and the Down Highway of little caliber is low; 2. after the spacing of two separating roller way was confirmed, the size of minimum pipe just had been limited.For general steel pipe, the big more wall thickness of caliber is also bigger, and corresponding joint close power is just big, and the required thrust of steel pipe propeller is also big.Use conventional locate mode V-type roller-way and have following problem: 1. the propeller height dimension is big, and 2. the minimum diameter of steel pipe is restricted; 3. stressed when big application point high, application point was low on the contrary in stressed hour, angle of rake tilting moment increases when causing big caliber steel pipe joint close.
The utility model content
The purpose of the utility model provides a kind of Prewelding machine steel pipe when carrying with the implement device of high location such as steel pipe Down Highway; Thereby realize minimizing of joint close caliber.
For this reason; Adopt following technical scheme: the implement device of locating with height such as steel pipe Down Highways when a kind of Prewelding machine steel pipe is carried; Comprise the steel pipe linking machine, the steel pipe propulsion plant is arranged on the center line of steel pipe linking machine, and left and right half rollgang of steel pipe is arranged in the side of steel pipe linking machine center line; Said left and right half conveying roller is installed on the bearing block of left and right half conveying roller; The bearing block of this left and right half conveying roller is installed on the left and right slide unit, and this left and right slide unit is installed on the left and right slide unit guideway, and left and right slide unit guideway is installed on the public base; The left and right leading screw that revolves that drives the slide unit motion links together with connector in the termination and is installed on the base said left and right leading screw is controlled left and right two halves conveying roller through rotation control mechanism the synchronous on-off that revolves.
The advantage of the utility model is:
1, steel pipe is carried high location such as pressing Down Highway; The ejector sleeve thrust point that can make the chain drive bobbin ejector remains unchanged with the distance of the application point of chain pull; And make this distance for minimum; Chain pull and ejector sleeve thrust are little to the tilting moment that bobbin ejector produces, bobbin ejector guide roller and guide rail stressed just little, and the physical dimension of bobbin ejector and guide rail is corresponding also little; Because the bobbin ejector height dimension is little, steel pipe was depressed in bobbin ejector yaw and the counter motion when bobbin ejector returned, and was always the yaw running roller and contacted with steel pipe, and make bobbin ejector body safety.
2, the V-type roller about two bodies can synchronous on-off effect, can change the position of steel pipe Down Highway.Position at the hour the most maximum steel pipe Down Highway of roller-way extended distance is the highest, and other steel pipe reduces according to the minimizing Down Highway of caliber gradually, changes the roller-way extended distance, can make the Down Highway of all prewelding steel pipes be in sustained height; Use steering gear and shaft coupling that the open-and-close mechanism of the several V-type rollers in a group is coupled together, the purpose of controlling with a cover motor reducer centralized driving, encoder is for easy and simple to handle, guarantees the height unanimity of a group or several groups of rollgangs.
3, realize minimizing of joint close caliber..The straight line bus of straight line V-type roller is changed into the curve bus of straight line and circular arc combination; The steel pipe that diameter is bigger is supported by the straightway bus; The steel pipe that diameter is little is supported by the arc section bus; Minimal openings one timing when left and right sides roller realizes the conveying of tubule footpath steel pipe, and the minimum delivery caliber can drop to Φ 210 by original Φ 508.
