Description
Technical field
The present invention relates to a kind of vertical pressure vessel cylinder schools to justify device, belongs to calibrator (-ter) unit technical field.
Background technology
With the fast development of chemical industry, in vessel fabrication industry, the application of large-diameter cylinder body is further extensive.However it presses
Force container may will produce various defects during machine-shaping and welding assembly and then influence the quality and performance of container,
These defects are mainly that drum surface shape is undesirable, and uneven, cylinder the section for generally comprising surface is non-round, weldering
The defects of misalignment of seam and seam angular deformation generate corner angle.The section of cylinder is non-round to refer to that cylinder is deposited on same section
In the difference of maximum gauge and minimum diameter, and in cylinder manufacturing process blanking, the processes such as roll and the dead weight of cylinder is all held
Single shell ring is easily set to generate certain ovality, the section of cylinder is non-round equally to will also result in local circumferential weld misalignment, to influence
Shell ring group welds quality.Therefore in cylinder manufacture and group to strictly controlling the out-of-roundness of cylinder in the process for improving pressure vessel cylinder
Body group has important role to efficiency and quality.The method that China is used to improve cylinder ovality is substantially artificial using card
The blue either fixtures such as angle bar are thick by processing master worker oneself judgement and the methods of steel pipe support being used to carry out in the appropriate case
Slightly adjust, gimmick is backward and precision is very poor, and final product quality with the ability of processing master worker it is strong and weak and it is irregular differ, adjust efficiency
Very low and waste of manpower.Therefore in equipment manufacture, the mechanization of assembling process is particularly significant.According to the relevant information,
Mechanical package is compared with manual tool assembling, is not only only capable of significantly improving working condition, and can raise labour productivity
Reach 50% or more.So the Cylinder assembly welding workstation with school circle device that research manufactures a set of high efficiency high quality exists
All it is necessary from the point of view of in terms of economy and practicability.
China already begins to focus on the problem of cylinder school circle, and preliminary analysis domestic scholars justify the school of steel pipe or cylinder
The research of method can be classified as following four major class：School circle class, supporting bar class, bolt, lead screw class and mechanical force is rolled to drive
Dynamic class.
Foreign countries cylinder form a team welder research in terms of starting than China it is early, especially Britain, Germany etc. industry skill
The fast-developing country of art is early a long time ago with regard to obtaining great success in terms of cylinder assembly mechanical and applied to real
It tramples in production.Major part in these assembly mechanicals can carry out the adjusting of cylinder ovality while assembling.
Invention content
Present invention mainly solves the technical issues of：The problem of for existing apparatus school circle inefficiency, low precision, the present invention
Provide a kind of vertical pressure vessel cylinder school circle device.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention：
Device, including upper bracket and main support are justified in a kind of vertical pressure vessel cylinder school, between the upper bracket and main support
It is provided with hydraulic lift, motor is provided on upper bracket, rotary shaft is connected below motor, rotates axis connection adjusting apparatus,
Adjusting apparatus both sides connect hydraulic telescopic rod, and hydraulic telescopic rod connects pressure head, and the main support is set on the base, on pedestal
It is provided with interior fixed component and outer fixing portion part, inside and outside fixed component bottom is both provided with running gear.
A kind of vertical pressure vessel cylinder school circle device application process be：The pressure container cylinder that school is justified will be needed vertical
It is placed on pedestal, interior fixed component is moved by running gear to both sides, and cylinder is propped up, and outer fixing portion part is filled by walking
It sets inwardly movement to be fixed on the base cylinder with one same-action of interior fixed component, the hydraulic pressure of adjusting apparatus both sides after cylinder is fixed
Telescopic rod is shunk, and hydraulic lift drives upper bracket to decline, and adjusting apparatus is transported to inner barrel, hydraulic telescopic rod is stretched
It is long, so that pressure head is resisted cylinder inboard wall, motor drives rotary shaft that adjusting apparatus is made to be rotated in inner barrel, and pressure head carries out barrel wall
School is justified, and lifting gear constantly declines during the circle of school, so that entire cylinder is obtained school from inside and is justified.
The side of the pressure head close to cylinder inboard wall is arc-shaped.
The interior fixed component and outer fixing portion part is each provided with four groups.
The beneficial effects of the invention are as follows：
A kind of vertical pressure vessel cylinder school circle device, including upper bracket and main support, upper bracket and master are devised in the present invention
It is provided with hydraulic lift between holder, motor is provided on upper bracket, motor is connected by rotary shaft with adjusting apparatus,
Adjusting apparatus both sides are provided with hydraulic telescopic rod, and hydraulic telescopic rod connects pressure head, can make pressure head cylinder by hydraulic telescopic rod
Inner wall, then adjusting apparatus rotation is driven by motor, so that the school that pressure head carries out cylinder inboard wall 360 ° is justified, compared to existing
School justify device, school of the invention justify effect it is more preferable, can improve cylinder school circle accuracy, and school circle it is more efficient.
