Description

One is suitable to various bore steel pipe circular seam welded stayed construction
Technical field
This utility model relates to construction, steel-pipe welding field, specifically one are suitable to the weldering of various bore steel pipe circular seam The supporting construction connect.
Background technology
Girth welding refers to the welding of various circle, circular weld, and the weld seam of welding fabrication is the annular closed.Mesh Before, for the girth welding of steel pipe, typically two sections of steel pipes to be docked are placed in H profile steel by boom hoisting, H type Steel, as supporting construction, then starts girth welding, first the most just welds position, then rotates steel pipe, will not The weld seam of welding forwards lower ground side, position to, then proceedes to welding, so goes round and begins again, be finally completed whole girth welding.
Current steel pipe support structure is fixing due to structure, it is impossible to all can play the steel pipe of all specifications well Support, the lowest part of steel pipe relative to support platform or too low or too high, no matter that situation, the most easily affect steel pipe Girth welding effect.
Utility model content
The purpose of this utility model is to provide one and is suitable to various bore steel pipe circular seam welded stayed construction, solves at present When carrying out girth welding, general supporting construction cannot adapt to different size steel pipe, causes girth welding quality affected Problem.
This utility model is achieved through the following technical solutions for solving technical problem: one is suitable to various bore steel pipe The supporting construction of girth welding, including supporting platform and being arranged on the two pieces of gripper shoes being oppositely arranged supported on platform, described Fagging is provided with some rollers, and the axis direction of roller is consistent with the bearing of trend of gripper shoe, described support platform is additionally provided with and leads Groove, the lower section of gripper shoe is provided with guide wheel, and guide wheel can be along guide groove movement;
Described gripper shoe be respectively arranged at two ends with a fastener, fastener is hinged with gripper shoe, and the both sides of described support platform set There are the some jacks matched with fastener.
In this programme, roller treats two joint steel pipes of girth welding for supporting, and roller can reduce steel pipe rotation process In the frictional force that is subject to so that rotating laborsaving;When in the face of the steel pipe of different size (size), by guide groove and the cooperation of guide wheel Effect, regulates the distance size between two pieces of gripper shoes, thus adapts to various steel pipe, makes the lowest part of steel pipe and supports between platform Be maintained at certain height or do not contact, thus avoiding steel pipe to produce deformation, be conducive to obtaining preferable welding effect and Quality, when gripper shoe position adjustments well after, the fastener at gripper shoe two ends is inserted respectively into support platform both sides jack in, Realize the locking to gripper shoe position, it is to avoid gripper shoe occurs sliding and affecting welding matter during steel pipe circular seam welds Amount.
Further, as optimal technical scheme, the roller in described gripper shoe is equally distributed.Use and equidistantly divide The roller that cloth is arranged can aid in the stress balance of steel pipe, it is to avoid steel pipe produces unnecessary supporting deformation, is conducive to obtaining Preferably welding quality.
Further, as optimal technical scheme, described fastener be shaped as L-shaped, one end of fastener is hinged with gripper shoe, The other end is free end.The fastener of L-shaped can match, in fastener is inserted into jack with the jack supporting platform both sides well After, it is possible to prevent gripper shoe from arbitrarily sliding.
Further, as optimal technical scheme, between adjacent two jacks of described support platform the same side away from From for 1 ~ 5cm.Distance between jack is unsuitable excessive, when the distance between adjacent two jacks is maintained at 1 ~ 5cm, and basic energy The distance between two gripper shoes is enough kept to disclosure satisfy that the steel pipe of all specifications.
Further, as optimal technical scheme, described gripper shoe be respectively arranged at two ends with a limited block.When treating circumferential weld After two joint steel pipes of welding are placed in two pieces of gripper shoes, steel pipe support is risen by roller, and the limited block at each gripper shoe two ends Being located just at outside the two ends of steel pipe, say, that steel pipe has been limited in gripper shoe by limited block, no matter how steel pipe turns Dynamic, can guarantee that steel pipe will not skid off from gripper shoe all the time, meanwhile, if between two limited blocks in same gripper shoe Distance is arranged properly, because the position-limiting action of limited block, it can be ensured that treat that two joint steel pipes of girth welding begin in rotation process It is maintained at relatively good contact eventually, does not i.e. have the situation that weld seam occurs becoming big in rotation process, thus without repeatedly The horizontal level of regulation two joint steel pipe, it is possible on the basis of guaranteeing reliable welding quality, shorten weld interval, improves work effect Rate.
Further, as optimal technical scheme, described limited block is perpendicularly fixed on two pieces of relative sides of gripper shoe. Limited block is arranged on the relative side of two pieces of gripper shoes the effect that can play limited block to greatest extent, steel pipe is risen To preferably position-limiting action.
Further, as optimal technical scheme, a length of 5 ~ 10cm of described limited block.When the length of limited block 5 ~ Time in the range of 10cm, it is possible to the steel pipe of each specification is played position-limiting action well, and limited block is difficult to impaired, limited block Service life is longer.
This utility model compared with prior art has the following advantages and beneficial effect:
(1) this utility model is by being arranged on gripper shoe on guide groove, under the mating reaction of guide groove and guide wheel, it is achieved that Distance regulation between two pieces of gripper shoes, thus adapt to various steel pipe, make to be maintained at one between the lowest part of steel pipe and support platform Fixed height or do not contact, thus avoid steel pipe to produce deformation, is conducive to obtaining preferable welding effect and quality, when The position adjustments of fagging well after, the fastener at gripper shoe two ends is inserted respectively into support platform both sides jack in, it is achieved to The locking of fagging position, it is to avoid gripper shoe occurs sliding and affecting welding quality during steel pipe circular seam welds.
(2) this utility model arranges limited block by the two ends in gripper shoe, it is possible to be limited to steel pipe well support On plate, no matter how steel pipe rotates, and can guarantee that steel pipe will not skid off from gripper shoe all the time, and meanwhile, limited block also can ensure that Treat that two joint steel pipes of girth welding remain at relatively good contact in rotation process, without occurring that weld seam is rotating During occur becoming big situation, thus without repeatedly regulating the horizontal level of two joint steel pipes, guaranteeing reliable welding quality On the basis of, additionally it is possible to shorten weld interval, improve work efficiency.
