Abstract
A welding longitudinal seam fitting-up device of a pressure vessel comprises a positioning chuck, channel steel members, positioning lugs, an oblique pin and a taper pin. The welding longitudinal seam fitting-up device of the pressure vessel is characterized in that a square hole is formed in the center of the bottom end of each channel steel member; a circular lug hole is formed at the upper end of each positioning lug; the pair of positioning lugs are symmetrically welded on both sides of the longitudinal seam of a cylinder; the pair of channel steel members are installed on the positioning lugs respectively; the corresponding channel steel members are clamped by bayonets at both ends of the positioning chuck lock. When the welding longitudinal seam fitting-up device of the pressure vessel is used, the taper pin is inserted into the circular lug holes of the positioning lugs, so that longitudinal seams are fit up longitudinally; and the oblique pin is inserted into a crevice inside the positioning lug and the channel steel members, so that the longitudinal seams are fit up crosswise. The welding longitudinal seam fitting-up device of the pressure vessel has the advantages of simple and compact structure, high stability and convenience in disassembly, and can fast and efficiently realize the regulating work of the longitudinal seam fitting up when the pressure vessel is welded, and in addition, the longitudinal seam fitting up has a higher precision.
Description
Technical field
The utility model relates to a kind of pressure vessel welding longitudinal joint group to device.
Background technology
The purposes of pressure vessel is very extensive.It is the equipment that each department in national economy such as petro chemical industry, energy industry, scientific research and military projects all plays an important role.Pressure vessel generally constitutes vessel by cylindrical shell, end socket, flange, potted component, perforate and six major parts such as adapter, bearing.In addition, also be furnished with safety device, table is taken into account the internals of finishing the various processes effect.Pressure vessel is owing to reasons such as sealing, pressure-bearing and media, blasts, burns on fire easily and jeopardize the safety of personnel, equipment and property and the accident of contaminated environment.At present, countries in the world are all classified it as important prison inspection product, by the specialized agency of national appointment, implement supervision and check and technical checking according to the rule and standard of national regulation.
Pressure vessel can be divided into monoblock type and combined type two big classes according to version, wherein monoblock type is also referred to as monolayered vessel, comprise roll of steel plate weldering formula, solid forging formula, electroslag shaping built-up welding formula, cast welding and built-up welding etc., modular container has multilayer binding formula, multilayer thermal sleeve, multilayer winding board formula, flute profile spirally-wound type and wrapping wire pressure vessel or the like.More than multiple version, its production technology majority is to be welded into shell ring by one or more longitudinal joint, connects into cylindrical shell by circumferential weld again between each shell ring then, the version that certainly yet has does not have longitudinal joint, forges weldering formula structure etc. such as individual layer.When the pressure vessel longitudinal joint is welded, because the deviation that causes of production technology on last stage, the deviation that causes such as technologies such as forging, pressure rollers, just need carry out opposite joint to longitudinal joint, to guarantee welding process requirement, guarantee the quality of product, therefore need use group, reach production requirement to guarantee weld job to frock.
The utility model content
The utility model provides a kind of pressure vessel welding longitudinal joint group to device, and the accurately group of longitudinal joint is right in the time of can realizing the pressure vessel welding, guarantees welding process requirement, guarantees product quality.
For achieving the above object, by the following technical solutions:
A kind of pressure vessel welding longitudinal joint group comprises positioning chuck, channel-section steel, chucking lug, taper pin, taper pin to device, it is characterized in that there is a square hole in described channel-section steel bottom central authorities, and there is a circular earhole chucking lug upper end; Described a pair of chucking lug is symmetrically welded at cylindrical shell longitudinal joint both sides, a pair of channel-section steel is installed on the chucking lug separately, the bayonet socket at chuck two ends blocks corresponding channel-section steel, during use, described taper pin is inserted the circular earhole of chucking lug, it is right that longitudinal joint is vertically organized, and described taper pin is inserted the slit of chucking lug and channel-section steel inboard, and it is right that longitudinal joint is carried out transverse set.
The utility model is simple and compact for structure, and stability is high, convenient disassembly, group during realization pressure vessel welding that can quickness and high efficiency is to adjusting work, and the longitudinal joint group is higher to precision, can low-costly, high efficiency finish group, effectively improve production efficiency, guarantee product quality operation.
