Description

ERW inside weld milling drum
Technical field
The utility model relates to a kind of interior welding line equipment for grinding, welding line milling drum in especially a kind of ERW.
Background technology
Along with the fast development of domestic and international oil, gas industry and urban pipe network, not only the demand to ERW increases greatly, and the quality requirement of welded tube is also improved constantly.The longitudinal submerged arc welded pipe inside weld should be removed apart from the inside weld reinforcement in each pipe end 150mm scope, make weld seam must not exceed the certain scope of contiguous steel pipe internal-surface, weld reinforcement is too high not only to influence carrying out smoothly of the water pressure test, and when pipe end is made film, can cause erroneous judgement to steel tube defect, for pipe quality has been buried accident potential.During at the scene to the steel pipe jam weld, reasonably the inside weld reinforcement is convenient to the butt joint of steel pipe, thereby helps the welding of steel pipe, improves welding quality.Weld reinforcement after the inside weld milling drum grinding does not at present reach requirement, often need manually to carry out at the construction field (site) the secondary grinding, Grinding wheel axis and weld seam were 180 ° of angles when it carried out grinding, there is wedge angle in the changeover portion of weld seam after the grinding, transition is not slick and sly, form stress concentration point easily, influence pipe quality.And present inside weld milling drum also needs to be provided with special Grinding wheel swelling device, structure more complicated.
The utility model content
The technical problems to be solved in the utility model provides a kind of advanced more ERW inside weld milling drum, and it can effectively control the reinforcement of ERW inside weld, has avoided the secondary grinding, the changeover portion slyness of weld seam after the grinding.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of ERW inside weld milling drum, it comprises walking dolly, be located at slide plate on the walking dolly, be located at the nose and the bistrique bearing that is connected with slide plate, the Grinding wheel of being located at the bistrique bearing and adjust wheel, and its key is to set up on the described slide plate carrying bolt that is used to regulate the bistrique bearing.
Above-mentioned Grinding wheel adopts elastomeric material, and this Grinding wheel is fixed with the abrasive band by provided thereon annular groove.
Above-mentioned bistrique bearing is connected with slide plate with the tension cylinder by bearing pin.
Above-mentioned walking dolly adopts the kind of drive of rack-and-pinion to move on guide rail; Moving both vertically of described slide plate by the kind of drive of leading screw and line slideway.
Adopt the beneficial effect that technique scheme produced to be: to regulate the elevation angle of bistrique bearing by carrying bolt, make the Grinding wheel grinding weld seam at an angle that tilts, thereby make the changeover portion slyness, eliminated stress concentration point, improved pipe quality; Can make the weld reinforcement after the grinding reach requirement by the mode of regulating carrying bolt and adjusting wheel according to the difference of caliber, grinding is accurate, has reduced job site workman's secondary grinding; Grinding wheel makes the abrasive band swelling by the centrifugal force of the rotation generation of self, does not need special expansion mechanism, and the swelling mode is simple and reliable; Lead screw transmission and accurate line slideway guiding are adopted in the lifting of slide plate, and leading screw utilizes motor reducer to drive, and is simple in structure, can utilize the self-locking of leading screw accurately to locate.

Wherein, 1, guide rail; 2, walking dolly; 3, slide plate; 4, carrying bolt; 5, tension cylinder; 6, bistrique bearing; 7, Grinding wheel; 8, adjust wheel; 9, abrasive band.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing 1, this ERW inside weld milling drum comprises walking dolly 2, is located at slide plate 3 on the walking dolly 2, is located at slide plate 3 front ends and the bistrique bearing 6 that is connected with slide plate 3, the Grinding wheel 7 of being located at bistrique bearing 6 and adjusts wheel 8 as can be known, and its key is to set up on the described slide plate 3 carrying bolt 4 that is used to regulate bistrique bearing 6.The weldering milling drum is advanced more in this ERW, regulates the elevation angle of bistrique bearing by carrying bolt 4, makes the Grinding wheel grinding weld seam at an angle that tilts, thereby makes the changeover portion slyness, has eliminated stress concentration point, has improved pipe quality; Can improve grinding accuracy by the adjusting control weld reinforcement of carrying bolt 4 and adjustment wheel 8, reduce the secondary grinding, alleviate working strength of workers.
Above-mentioned Grinding wheel 7 adopts elastomeric material, and this Grinding wheel 7 is fixed with abrasive band 9 by provided thereon annular groove.Grinding wheel 7 rotation at a high speed under the drive of motor during work, under action of centrifugal force, the breach of rubber wheel expands outwardly, and the abrasive band automatic swelling of 9 meetings saved special expansion mechanism, and swelling is reliable on Grinding wheel 7.
Above-mentioned bistrique bearing 6 is connected with slide plate 3 with tension cylinder 5 by bearing pin.
Above-mentioned walking dolly 2 adopts the kind of drive of rack-and-pinion to move on guide rail; Moving both vertically of described slide plate 3 by the kind of drive of leading screw and line slideway.Dolly advancing on guide rail 1 adopted decelerator driven gear rack for transmission mode, and decelerator adopts the variable-frequency motor of rotating to drive and has brake function; Lead screw transmission and accurate line slideway guiding are adopted in the vertical adjustment of slide plate, and leading screw utilizes motor reducer to drive, and transmission performance is reliable, operates steadily.
The supporting guide rail 1 that is provided with below the above-mentioned walking dolly 2.
Go up the sensor that is used for checkout equipment or steel pipe running status that this ERW inside weld milling drum also comprises supporting setting.
Above-mentioned this ERW inside weld milling drum also comprises the sensor that is used for checkout equipment or steel pipe running status of supporting setting.Can improve the automation of whole system, intelligent degree like this, guarantee that milling drum always is in duty safely and effectively, the equipment or the personal injury that avoid various fortuitous events to bring.
During work, after steel pipe arrives grinding position, motor reducer on the dolly 2 starts, transmission drive dolly 2 by rack-and-pinion advances, and when Grinding wheel 7 reached pipe end, the motor reducer band-type brake on the dolly 2 was checked, the motor that Grinding wheel 7 links to each other rotates at a high speed, the driven by motor slide plate 3 of slide plate 3 moves on up to the grinding of finishing the pipe end inside weld, and the counter-rotating of the motor of slide plate 3 drives the position before slide plate 3 is got back to grinding, and the motor reducer counter-rotating on the dolly 2 drives dolly 2 and retreats into original position.According to the difference of grinding caliber, the position of slide plate 3 also changes thereupon in the course of work, and the employing motor reducer drives leading screw and realizes the lifting of slide plate 3 along line slideway; According to the requirement of weld seam grinding reinforcement, by adjusting carrying bolt 4 and adjusting the inclination angle that wheel 8 is regulated Grinding wheel 7, after adjusting to the right place, strain cylinder 5 work, fix the position of bistrique bearing.
Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
