Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a lateral movement comparator. Background Technology

[0002] This invention is mainly applied to the air gouging and submerged arc welding process of the outer circumferential seam of railway tank cars. When the tank body rotates on the roller frame, it will move laterally. For many years, this lateral movement of the tank body during rotation has had a significant impact on the submerged arc welding operation of the outer circumferential seam of the tank, such as increasing the difficulty of the welder's operation and often leading to weld deviation and increased rework. Moreover, the lateral movement of the tank body during rotation has been a major obstacle to the automation of air gouging and submerged arc welding of the outer circumferential seam of the tank.

[0003] When a worker faces the tank and the tank rotates upwards, the tank moves laterally towards the worker's left. Current technology involves placing the tank on rollers for free rotation during air gouging and submerged arc welding of the tank's outer circumference. During these operations, the worker must track the tank's lateral movement; even slight negligence can cause the gouged groove or weld bead to deviate from the weld center, resulting in incomplete penetration defects that fail X-ray inspection and require rework. This problem has also been a major obstacle to automating air gouging of the tank's outer circumference. Summary of the Invention

[0004] The purpose of this invention is to provide a lateral movement correction device for a tank body, which can prevent lateral movement of the tank body during rotation processing, so that when the tank body rotates on the roller frame, the outer circumferential seam always rotates along the vertical line, thereby reducing the operational difficulty of air gouging and submerged arc welding of the outer circumferential seam, and laying the foundation for subsequent research on automatic air gouging and automatic submerged arc welding of the outer circumferential seam of the tank body.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0014] exist Figures 1 to 5 As shown in the schematic diagram of this utility model, a lateral movement and alignment device for a tank mainly includes an alignment wheel assembly 1, a height adjustment seat 2, and a fixed base 3. The height adjustment seat 2 is mounted on the fixed base, and the alignment wheel assembly 1 is fixed to one side of the upper part of the height adjustment seat 2. The alignment wheel assembly includes a reinforcing bushing 4, a turntable, rolling bearings, pressure bearings, and a central roller. A circular groove A is formed on one end face of the reinforcing bushing 4, and one side of the pressure bearing 5 is embedded in the circular groove A. Two circular grooves B are formed on the inner wall of the reinforcing bearing, and rolling bearings 6 are embedded in both grooves B. A circular groove C is formed on one side of the turntable, and the other side of the pressure bearing is embedded in the circular groove C. A central roller 8 is fixed to one side of the turntable 7, and the central roller is embedded inside the rolling bearing.

[0015] The fixed base includes a base side plate A, a base side plate B and a base 12. The base side plate A9 and the base side plate B10 are fixed on the base 12. Several positioning holes 11 are respectively opened on the base side plate A and the base side plate B.

[0016] The height adjustment seat includes a cuboid frame, lifting seat side plate A, lifting seat side plate B, fixing bolts, a top sealing plate, and lifting lugs. Lifting seat side plate A and lifting seat side plate B are fixed to both sides of the cuboid frame 14. Several adjustment holes 19 are formed on lifting seat side plates A17 and B18, with the vertical spacing between the adjustment holes and the positioning holes being the same. When adjusting the height, several fixing bolts 20 are inserted and inserted to lock the adjustment. The cuboid frame is welded from square steel and fixed to lifting seat side plates A and B. A reinforcing bushing for the orthogonal wheel assembly is provided on the upper plane of the cuboid frame. A top sealing plate 15 is provided on the upper part of the orthogonal wheel assembly, and lifting lugs 16 are fixed to the top sealing plate to facilitate the lateral movement of the tank and the movement and lifting of the orthogonal device.

[0017] Preferably, the outer sides of the base side plate A and the base side plate B are provided with reinforcing ribs 13, and the bottom of the reinforcing ribs is fixed to the base.

[0018] In use, the tank body of this invention is formed by the joining of six cylindrical sections 25 and end caps 22, resulting in a slightly conical tank weighing nearly 10 tons. The joining of the cylindrical sections and end caps creates seven circumferential seams 23. These seams require initial submerged arc welding of the inner seams, followed by air gouging and welding of the outer seams. The outer seam machining requires the tank body to be rotated at a constant speed on a roller frame 24. However, when a person faces the tank, if the tank rotates upwards, it tends to move laterally to the left. Therefore, by installing a lateral movement correction device on the left side, the lateral movement of the tank body can be restricted.

[0019] Before installation, fix the roller frame 24 on the base, place the tank on the roller frame, and ensure that the center of the tank is basically aligned with the center of the two roller frames.

[0020] During installation, first use an overhead crane to suspend the lifting lugs, then raise the height lifting platform until the center of the circular turntable is aligned with the lifting lugs on the tank head. Simultaneously, align the adjustment hole on side plate A of the lifting platform with the positioning hole 11 on side plate A of the base. Figure 2 As shown, multiple fixing bolts 20 are inserted into the adjustment hole and the positioning hole and locked in place.

[0021] like Figure 1 As shown, after the height is adjusted, the horizontal movement of the tank is carried to the left side of the tank by a crane through the lifting lug 16, and the circular turntable is placed against the lifting lug 21 on the tank head.

[0022] Secure the base firmly using buried bolts or square steel.

[0023] When the tank rotates and causes lateral movement, the lifting lugs on the tank head will rest against the circular turntable, causing the turntable to rotate and reducing frictional resistance. This achieves the purpose of limiting the lateral movement of the tank.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
