Description
Technical field
The present invention relates to the manufacture field of tank body of tank car, be specifically related to a kind of method utilizing magnetcisuspension pin to carry out secondary tank line.
Background technology
At present, in China railways tank car tank body manufacture process, secondary line is general adopts pneumatic top method of scoring, and its principle is as shown in Fig. 1 a, Fig. 1 b, Fig. 1 c.Secondary tank line tire is made up of a secondary roller frame and two, two ends reservoir, and the center of reservoir is located on the longitudinal centre line of two turning rolls, and namely the top secondary tank that is positioned at of reservoir is rule on the center line (datum line) of tire.
During work, winched to by tested tank body overhead traveling crane on the turning rolls of secondary line tire, start reservoir and rise top, it is top that rotation tank body first makes the pre-bottom bus bar (primary line) drawn of one end aim at reservoir, and now stop operating tank body; Measure the top deviate A with bottom bus bar (primary line) of other end reservoir, the half A/2 getting this value, as the foundation revising tank base bus (primary line), finally marks the bottom bus bar of tank body, i.e. secondary line again according to correction value A/2.
The shortcoming of prior art: because secondary tank line two reservoirs of tire and the pedestal of turning rolls are welding as one, impact is there will be in tank body landing process, cause reservoir pedestal bias or skew, Long-Time Service, the crooked phenomenon of the meeting top appearance of reservoir can be caused, affect the accuracy of secondary line, as shown in Figure 2.
Summary of the invention
The object of the invention is: provide a kind of method utilizing magnetcisuspension pin to carry out secondary tank line, the reservoir pedestal solving existing pneumatic top method of scoring impacts due to tank body landing and eccentric or skew occurs, and affects the technical problem of the accuracy of secondary line.
Technical solution of the present invention is:
Utilize magnetcisuspension pin to carry out a method for secondary tank line, its special character is: comprise the following steps:
1) make secondary line tire, secondary line tire marks the center line of secondary line tire in advance; Using the bottom bus bar marked in advance in tank base as primary line;
2) hung by tank body on the turning rolls of secondary line tire, rotation roller frame, makes the primary line of tank body generally within immediately below tank body;
3) a magnetcisuspension pin is hung at the two ends of the primary line marked in advance in step 1) respectively, and magnetcisuspension pin one end to be adsorbed on tank body and in naturally drooping state;
4) rotate tank body, first make the vertical projection of the magnetcisuspension pin of one end and secondary tire center line of ruling overlap, now stop operating tank body;
5) measure the vertical range A of the vertical projection distance secondary line tire center line of the magnetcisuspension pin of the other end, get A/2 as the foundation revising tank body primary line;
6) bottom bus bar of tank body is again marked according to correction value A/2, as secondary line.
Advantage of the present invention is:
(1) to be rule by the magnetcisuspension pin that suspends in midair below tank body of tank car and secondary the comparison of tire center line (datum line), complete the secondary line of tank body, guarantee the drawn line quality of tank base bus (longitudinal centre line secondary line), meet the requirement to bus precision in tank body manufacture process.
(2) technique is simple, eliminates and weld the top step of reservoir on the longitudinal centre line of turning rolls, saves operation and cost.
(3) secondary line tire center line and secondary tire of rule is not connected, and secondary line tire center line can be drawn on the ground, avoids Long-Time Service secondary tire of ruling and is out of shape impact for center line.

Detailed description of the invention
The features such as the maximum technical characterstic of the present invention is the magnetcisuspension pin that tank body two ends use, and it is core place of the present invention, and its below tank body, has hanging rapidly, accurate positioning according to magnetic-adsorption, easy to operate.
Utilize magnetcisuspension pin to carry out a method for secondary tank line, comprise the following steps:
1) make secondary line tire, secondary line tire marks the center line 6 of secondary line tire in advance; Using the tank base bus 5 marked in advance in tank base as primary line;
2) hung by tank body 1 on the turning rolls of secondary line tire, rotation roller frame 2, makes the primary line of tank body generally within immediately below tank body;
3) a magnetcisuspension pin 3 is hung at the two ends of the primary line marked in advance in step 1) respectively, and magnetcisuspension pin one end to be adsorbed on tank body and in naturally drooping state;
4) rotate tank body, first make the vertical projection of the magnetcisuspension pin of one end and secondary tire center line of ruling overlap, now stop operating tank body;
5) measure the vertical range A of the vertical projection distance secondary line tire center line of the magnetcisuspension pin of the other end, get A/2 as the foundation revising tank body primary line;
6) bottom bus bar of tank body is again marked according to correction value A/2, as secondary line.
Existing method needs at secondary line tire center line welding reservoir top, need the perpendicularity ensureing reservoir top 4, complex process, cost is high, tank body landing is impacted and eccentric or skew is occurred, and also can affect the accuracy of secondary line, and present invention omits this step, not only save operation, the accuracy of secondary line can also have been improved.The center line (datum line) 6 of secondary line tire of the present invention is drawn on turning rolls pedestal, can effectively prevent from causing secondary line tire center line (datum line) to occur the situation of skew because of pneumatic top Long-Time Service distortion.
The present invention's magnetcisuspension pin used is an elongated needle, and after tank body hangs on the turning rolls of secondary line tire, the length of magnetcisuspension pin can not exceed the vertical range of bottom bus bar distance secondary line tire.
Key problem in technology point of the present invention is used magnetcisuspension pin, utilize the magnetic of magnetcisuspension pin and be hung on tank body lower part, for detecting the deviation that tank body bus (primary line) occurs, and then find out difference correction, finally mark revised tank base bus 7, i.e. secondary line, this method is applicable to the line of various forms of tank body of tank car secondary.
