Along with the continuous progress of China's manufacturing equipment, the installation quantity of large-scale cylindrical workpiece and required precision also improve constantly.Particularly diameter is at the cylindrical work of Ф 1000 ~ 6000mm or industrial pipeline, the feature such as have that volume is large, Heavy Weight, welding are yielding, need the precision strictly controlling its assembling centering when mounted, if coaxiality error is excessive after installing, workpiece is easily caused to tilt, rotary type equipment is beated excessive in the running, the serious consequence such as even can produce fracture, collapse.
Before the utility model not yet occurs, large-scale cylindrical workpiece is when Horizontal type assembly welding, first sleeper on the pad of workpiece bottom, by chain block or jack, two sections of workpiece to be assembled are carried out counterpart centering, weld respectively to do to support between workpiece with ground with shaped steel again after axiality and linearity meet the requirements and fix, in order to avoid work swings produce Influence of Displacement assembly precision.The welding manner of different azimuth is adopted to be linked into an integrated entity by the workpiece that two sections need be assembled after fixing workpiece.Like this when the workpiece that weld diameter is larger, top weld seam needs to put up a ladder welding, and bottom weld seam will adopt overhead welding, and the liftoff space of bottom weld seam is less sometimes, also need the shaped steel of fixation workpiece to cut off, carry out multiple welding by after the two sections of workpiece turning that need assemble angles.Problems existing is, because diameter of work size is large, Heavy Weight, need during welding to set up scaffold, adopt multi-faceted welding, have impact to welding efficiency, welding quality and operational security, workpiece assembling centering is wasted time and energy, and labour intensity is large, and easily causing workpiece deformation during chain block adjustment, secondary reverse welding needs to employ crane sometimes; May be difficult to ensure due to assembled workpiece linearity and coaxiality deviation time serious, cause workpiece to tilt, running time beat excessive, there is considerable safety and quality accident hidden danger in the security incident such as even produce fracture, collapse.
Utility model content
In order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of large-scale cylindrical workpiece assembling alignment device, this apparatus structure is simple, easy to operate, effectively can ensure the linearity that workpiece is assembled and coaxial accuracy, save workpiece assembling alignment time, workpiece assembly welding is safe and efficient, ensures to produce and carries out smoothly.
Large-scale cylindrical workpiece assembling alignment device, be characterized in that this device is made up of a pair identical, of the same size frame of shape and structure, each frame is established the scale of strip length scale and symmetrically arranged backing roll, movable stand and regulating handle, backing roll by rotating shaft support in the kidney-shaped slideway of frame both sides, the central axis of two backing rolls and the central axes of frame, backing roll upper surface line is parallel to the central axis of frame.During use, according to the position of docking workpiece, by separated at workpiece two to be assembled for two groups of frames, then according to diameter and the road clearance of workpiece, regulate the spacing of backing roll by rotating regulating handle
wherein R is the radius of workpiece to be assembled, and r is the radius of backing roll, and L is the centre-to-centre spacing of two backing rolls, measures by the scale in frame.The object of prior adjustment backing roll centre-to-centre spacing is to ensure that workpiece to be assembled is being fallen after on alignment device, workpiece outer wall can be made to contact with backing roll, in order to avoid the excessive upper surface causing workpiece directly to fall alignment device frame of two backing roll spacing causes workpiece to swing.
When workpiece to be assembled winches on backing roll, regulate to the left or to the right by regulating two backing roll spacing on alignment device and entirety, make cylindrical work produce relative movement, thus reach the height, levelness and the linearity object that regulate workpiece, realize fast aligning center.Simultaneously by the rotation of backing roll, drive workpiece to rotate, be convenient to assembling and the welding of workpiece.
The utility model improves further, described frame cross section is square channel-shaped, and its groove depth is greater than the radius of backing roll, and on the two side of frame length direction, symmetry offers kidney-shaped slideway, bidding chi below kidney-shaped slideway, the center-zero line of scale and the longitudinal centre line of frame are on same vertical plane; On the two side of frame width, symmetry offers round tube hole, and the line of centres of two through hole and the cross central line of frame are on same vertical plane.
The utility model improves further, and the rotating shaft of described backing roll is arranged on backing roll and movable stand, and rotating shaft two ends are placed in the kidney-shaped slideway of frame; Described regulating handle is fixed in the through hole of frame by bearing and only rotates, and the other end of regulating handle is established external screw thread and is threaded with adopting between movable stand.
The utility model improves further, and described movable stand takes the shape of the letter U shape, and its two ends establishes installing hole, and the diameter of installing hole and rotating shaft form interference fit; Movable stand establishes screwed hole, its central axis overlaps with the line of centres of frame through hole, if threaded regulating handle and movable stand threaded engagement, without the need to lock handle behind centering center, reached the self-locking of workpiece by the frictional force between workpiece and backing roll, ensure the precision of two supporting device adjusted in concert.
Compared with prior art, advantage is novel, compact conformation, rationally, and volume is little, is convenient to transport and handling; This device adopts the supporting base used in pairs, not only improve the assembly precision of large-scale cylindrical workpiece, save workpiece assembling alignment time, reduce the labour intensity of operator, improve longitudinal and girth welding efficiency and the security of workpiece, improve direction of welding, more effectively ensured welding quality, the business enterprise expand being applicable to be engaged in the manufacture of large-scale pipeline, container and cylinder class and assembling uses.
