Abstract

The invention belongs to the field of machining and welding of cylinders in the machinery industry, and relates to a flexible rail device of a trolley for cylinder circular seam welding and an application method of the flexible rail device. The difficulty that a submerged-arc welding trolley cannot be adopted during cylinder circular seam welding in the prior art is overcome. The flexible rail device is structurally provided with an inner rail (1), an outer rail (2), screws (3) and the like. The section of each rail is in an equilateral triangle shape. The inner rail (1) is inserted into the outer rail (2), and the inner rail (1) and the outer rail (2) are combined into flexible rails (5). The flexible rails (5) are attached to the circumference of a cylinder to be welded, and a circular ring is formed. One end of each flexible rail can be pulled out of or stretch into the other end of the corresponding flexible rail to change the diameter of the corresponding rail, and the rails are screwed and fixed by the screws (3). The submerged-arc welding trolley can stably and continuously run on the flexible rails without being limited by welding geographic positions or the diameter of the cylinder, and equipment cylinder inside and outside circular seam welding is carried out conveniently. The device is a flexible device, and therefore the diameter of the rails can be adjusted within a certain range to adapt to inside and outside circular seam welding of cylinders of different diameters.

Description

Circumferential Welds In Cylinders welding tractor flexible rail device and using method thereof
Technical field
The invention belongs to machinery industry cylindrical shell processing welding field.
Background technology
The diameter of oil refining equipment barrel varies, and existing narrow gap device head is comparatively large, and some equipment barrel diameter is less, and the welding of interior circumferential weld cannot be carried out in narrow gap; Or device diameters is excessive, narrow gap cross insufficient height, cannot carry out girth welding too.Submerged arc welding carriage has lightweight, and equipment is simple, be easy to the advantages such as transport, but submerged arc welding carriage can only be used for the welding of cylindrical shell longitudinal seam now.How to make submerged arc welding carriage by the restriction of welding geographical position or barrel diameter size, the technical barrier that the seam welding of equipment barrel inner and outer ring is urgent need solution now can not be carried out.
Summary of the invention
The problem that we will solve is: overcome prior art when Circumferential Welds In Cylinders welds, because equipment barrel diameter is less or device diameters is excessive and submerged arc welding carriage cannot be used to carry out the difficulty of girth welding.
The invention provides a kind of Circumferential Welds In Cylinders welding tractor flexible rail device, its structure has inner orbit 1, outside track 2, screw 3 etc., and rail section is equilateral triangle; It is inner that inner orbit 1 inserts outside track 2, and inner orbit 1 and outside track 2 are connected to one by screw 3; Described inner orbit 1, the total length of outside track 2 are greater than the circumferential length of soldered cylindrical shell.
Described inner orbit 1, outside track 2 material are high-temperature flexible material.
The using method of Circumferential Welds In Cylinders welding tractor flexible rail device:
1. inner orbit 1 is inserted outside track 2, be combined as flexible rail 5; Being fitted in flexible rail 5 and cylindrical shell border to be welded, is annular; Tighten fixing with screw 3;
2. parallelly fix two flexible rails 5, distance be the wheelspan of welding tractor 4, and placement welding tractor 4 is on flexible rail 5;
3. cylindrical shell rolls on turning rolls 6, regulates welding tractor 4 and turning rolls 6 speed of service; Make the linear velocity of cylindrical shell circumferential welded seam 7 identical with welding tractor 4 speed of service and direction is contrary;
4. keep welding tractor 4 and turning rolls 6 geo-stationary all the time, when welding tractor 4 is welded, be in downhand position all the time;
5. after debugging well, welding is carried out to equipment barrel;
6. after welding terminates, unscrew inner orbit screw 3, take off flexible rail 5, to use next time.
The invention has the beneficial effects as follows, submerged arc welding carriage can be made by the restriction of welding geographical position or barrel diameter size, lasting running on flexible rail can not to be stablized, carry out the seam welding of equipment barrel inner and outer ring very easily.This device is flexible apparatus, can the diameter of adjustable track within the specific limits, to adapt to the inner and outer ring seam welding of different-diameter cylindrical shell.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the structure of Circumferential Welds In Cylinders welding tractor flexible rail device has: inner orbit 1, outside track 2, screw 3 etc., and rail section is equilateral triangle; It is inner that inner orbit 1 is enclosed within outside track 2, and inner orbit 1 and outside track 2 are connected to one by screw 3; Described inner orbit 1, the total length of outside track 2 are greater than the circumferential length of soldered cylindrical shell.
Described inner orbit 1, outside track 2 material are high-temperature flexible material.
As shown in Figure 3, Figure 4, the using method of Circumferential Welds In Cylinders welding tractor flexible rail device:
1. inner orbit 1 is inserted outside track 2, be combined as flexible rail 5; Being fitted in flexible rail 5 and cylindrical shell border to be welded, is annular; Tighten fixing with screw 3;
2. parallelly fix two flexible rails 5, distance be the wheelspan of welding tractor 4, and placement welding tractor 4 is on flexible rail 5;
3. cylindrical shell rolls on turning rolls 6, regulates welding tractor 4 and turning rolls 6 speed of service; Make the linear velocity of cylindrical shell circumferential welded seam 7 identical with welding tractor 4 speed of service and direction is contrary;
4. keep welding tractor 4 and turning rolls 6 geo-stationary all the time, when welding tractor 4 is welded, be in downhand position all the time;
5. after debugging well, welding is carried out to equipment barrel;
6. after welding terminates, unscrew inner orbit screw 3, take off flexible rail 5, to use next time.
If adjustable range is greater than track length one half, can according to the flexible rail of the customized different length of on-the-spot cylindrical shell circumferential length.
