Abstract
A kind of large thin-wall tank body holds round frock, and comprise left semicircle arc fagging, right semi-circle arc fagging, two jockeys, two or more reinforcement, left semicircle arc fagging two ends are connected to form an annulus through jockey and right semi-circle arc fagging two ends; Each jockey comprises connecting plate, and connecting plate one end is connected with left semicircle arc fagging through bolt and nut one, and the connecting plate other end is provided with opening, and the bolt and nut two of the connecting plate other end through being loaded on opening part is connected with right semi-circle arc fagging; Each reinforcement two ends are respectively equipped with more than one open slot, and the bolt and nut three of each reinforcement through being loaded on open slot place is loaded on left semicircle arc fagging, right semi-circle arc fagging.The circumference of round can cylindrical shell all can be held round after the utility model assembling, for tank body cylindrical shell and cylindrical shell, each portion of Cylinder and end socket assembly welding, dock.Before and after tank body integral solder, prevent distortion, work the effect of holding round.Quick release after tank body welding completes, conveniently takes out in the manhole of tank body.
Description
Technical field
The utility model belongs to Machining Technology field, is specifically related to circle supporting device during a kind of large-scale oblique cone thin-wall case docking welding processing.
Background technology
At present, the docking of known large thin-wall cylinder joint pushes away support frock (holding round frock) structure and is made up of screw rod, nut, jacking block etc., radial screw rod extruding device is had to be equipped with the adjustment such as outer bolt, wedge, also have a kind of arc spiral circle supporting device, be entirety more than half circular arc in be provided with spiral lever and can outwards open to play and prevent cylindrical work pieces to be out of shape and eliminate local deformation effect.Radial screw rod extruding device is one or more band screw rods, holds round in inner barrel, and it just plays holding workpieces to local, prevents from being out of shape and pulling up the effect of distortion.Arc and radial circle supporting device can only eliminate local deformation, whole circular section can not be held round, and need to be aided with outer bolt, wedge regulates.Extruding device and arc circle supporting device structure are comparatively large, cannot withdraw from, or withdraw from difficulty after the tank body welding be made up of large-scale shell ring from manhole.
Summary of the invention
Can only eliminate the local deformation of cylindrical shell circumference to overcome existing circle supporting device, the deficiency cannot withdrawn from from manhole after the tank body welding of large-scale shell ring composition, the utility model provides a kind of detachable large thin-wall tank body to hold round frock, and structure is simple, easy to use.
The technical solution of the utility model is: comprise left semicircle arc fagging, right semi-circle arc fagging, two jockeys, two or more reinforcement, and left semicircle arc fagging two ends are connected to form an annulus through jockey and right semi-circle arc fagging two ends; Each jockey comprises connecting plate, and connecting plate one end is connected with left semicircle arc fagging through bolt and nut one, and the connecting plate other end is provided with opening, and the bolt and nut two of the connecting plate other end through being loaded on opening part is connected with right semi-circle arc fagging; Each reinforcement two ends are respectively equipped with more than one open slot, and the bolt and nut three of each reinforcement through being loaded on open slot place is loaded on left semicircle arc fagging, right semi-circle arc fagging.
Described left semicircle arc fagging two ends have pilot hole one, connecting plate one end have the locating hole one corresponding with pilot hole one, and bolt and nut one is loaded on pilot hole, locating hole place.
Described right semi-circle arc fagging two ends have the pilot hole two corresponding with the opening on connecting plate, and bolt and nut two is loaded on pilot hole two, opening part.
Have the pilot hole three corresponding with the open slot on reinforcement in the middle part of described left semicircle arc fagging, right semi-circle arc fagging, bolt and nut three is loaded on pilot hole three, open slot place.
The utility model adopts two semi arch faggings as the support of cylinder circular section, two halves circular arc is each up and down to be connected by a rotatable opening connecting plate, for proof strength, design that two angle steel have bolt with circular arc fagging, nut is connected and plays a supporting role in loading process.Opening connecting plate and left side semi arch fagging with bolts, and be with top nut, form rotatable state, shifting two circle arc support plates onto in cylinder relevant position, when allowing circular arc outer wall and cylinder inboard wall fit completely, connecting plate is turned to horizontal level, and connect with bolt, nut, tighten.Play the distortion eliminating whole cylindrical barrel like this.And the rotatable connecting plate of opening and angle steel stiffener are all detachable, conveniently take out from stayed manhole after barrel soldering completes.The circumference of round can cylindrical shell all can be held round under duty, for tank body cylindrical shell and cylindrical shell, each portion of Cylinder and end socket assembly welding, dock.
The utility model can be used for the docking of tilted conical thin-walled tank shell and the welding processing of 16 meters long, and can take out from stayed manhole after formed product, and structure is simple, without the need to other auxiliary mould.The utility model circular arc outer wall and cylinder inboard wall are fitted completely, play the distortion eliminating whole cylindrical barrel.And the rotatable connecting plate of opening and angle steel stiffener can be for convenience detach, be beneficial to assembling again.The utility model greatly reduces processing cost, shortens the processing duration, and can reuse.What the utility model was applicable to the large-diameter circular conical shell that all middle thin plate high circularity requires holds round processing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is using state figure of the present utility model.
Detailed description of the invention
In Fig. 1, the circular hole of connecting plate 2 one end is connected with fagging 1 by bolt and nut one, and other end open pore is free to rotate, when turn to as shown in Figure 1 position time to be connected with fagging 1 by bolt and nut two and to tighten, be duty; Only need loosen the coupled bolt and nut two on fagging 1 when needing to take off, connecting plate 2 being rotated and opens.Two strengthen angle steel (reinforcement) 3 open slot, being connected, only loosening bolt and nut 35 when dismantling, can dismantle and strengthen angle steel 3 by bolt and nut 35 with right semi-circle arc fagging 1.Above-mentioned connected mode can prevent in cylindrical shell, dismantle bolt and nut and connecting plate 2 miniature parts when taking out frock and drop.Fagging 1 comprises left semicircle arc fagging, right semi-circle arc fagging.
In Fig. 2, operationally, be provided with two the utility model devices 7,9 at the two ends of cylindrical shell 8, and be all advance to little nose circle from cylindrical shell great circle one end, when position, need certain external force to push it to corresponding operating position and hold round.After cylindrical shell and cylindrical shell, the whole erection welding of Cylinder and end socket are combined into tank body, then dismantle in tank body, take out from manhole.
