[0041] The air storage cylinder is the air source storage element of the air brake system of the industrial and mining electric locomotive, and is the air pressure storage source of the brake system of the industrial and mining electric locomotive. The air storage cylinder includes an air cylinder body and an air cylinder head welded at both ends of the air cylinder body. The welding quality of the air cylinder head and the air cylinder body has high requirements. Only the air storage cylinder with qualified welding can ensure the normal use of the air source of the air brake system of the industrial and mining electric locomotive, thereby ensuring the safe, stable and reliable operation of the industrial and mining electric locomotive. In the related technology, the welding method of the air cylinder body and the air cylinder head usually adopts the method of one person rotating the air cylinder body and one person welding. Due to the uneven rotation speed of the air cylinder body, the air cylinder body and the air cylinder head will have the phenomenon of surfacing, leaking welding, uneven welding meat, etc. during welding. The success rate of one-time welding is low, resulting in a lot of rework, low welding efficiency, long working hours, high cost, and it is difficult to meet the current production needs. In addition, if welding leaks are found in the air storage cylinder during water pressure test and sealing test, that is, water seepage, air leakage, etc. occur in the air storage cylinder, rework and welding are required, which consumes a lot of manpower and materials.

[0042] In view of this, the embodiment of the present application sets a bracket, and sets a rotating support mechanism on the bracket. The rotating support mechanism supports the air storage cylinder of the industrial and mining electric locomotive and drives the air storage cylinder to rotate at a uniform speed, so that the welding personnel can evenly weld the air cylinder body and the air cylinder head, so as to reduce the phenomena of surfacing, leaking welding, uneven welding and the like when welding the air cylinder body and the air cylinder head.

[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] Figure 1 This is a front view of the welding device for the air storage cylinder of an industrial and mining electric locomotive according to an embodiment of the present application. Figure 2 This is a side view of the welding device for the air storage cylinder of an industrial and mining electric locomotive according to an embodiment of the present application. Figure 3 It is a top view of the welding device for the air storage cylinder of an industrial and mining electric locomotive according to an embodiment of the present application.

[0045] like Figure 1 , Figure 2 and Figure 3As shown, the welding device for the air storage cylinder 300 of the industrial and mining electric locomotive provided in this embodiment includes a bracket 100 and at least one rotating support structure, and each rotating support mechanism 200 is arranged on the bracket 100. The rotating support structure includes a driving member and two supporting shafts 210, and the two supporting shafts 210 are arranged side by side and at intervals. Each supporting shaft 210 can be rotatably installed on the bracket 100, and the driving member is connected to one of the supporting shafts 210 and drives the supporting shaft 210 to rotate. The rotating support mechanism 200 is configured to support the air storage cylinder 300 of the industrial and mining electric locomotive and drive the air storage cylinder 300 to rotate at a uniform speed. That is, an air storage cylinder 300 is placed on a rotating support structure to complete the welding of the air cylinder barrel 310 and the air cylinder head 320 of the air storage cylinder 300. When welding the air cylinder barrel 310 and the air cylinder head 320 of the air storage cylinder 300, the air cylinder head 320 and the air cylinder barrel 310 are firstly spot welded to make the air cylinder head 320 and the air cylinder barrel 310 docked. Then, the air cylinder barrel 310 docked with the air cylinder head 320 is placed on two supporting shafts 210. The rotating shaft 210 cooperates with the support to connect the air cylinder body 310 with the air cylinder head 320. The supporting rotating shaft 210 connected with the driving member rotates at a constant speed under the driving action of the driving member to drive the air cylinder body 310 connected with the air cylinder head 320 to flip over. The air cylinder body 310 connected with the air cylinder head 320 is blocked and supported by the supporting rotating shaft 210 not connected with the driving member. The air cylinder body 310 connected with the air cylinder head 320 rotates at a constant speed on the two supporting rotating shafts 210. The uniform rotation of the air cylinder body 310 connected to the air cylinder head 320 makes it easier for welding personnel to weld the air cylinder body 310 and the air cylinder head 320, thereby reducing the occurrence of surfacing, leaking welding, uneven welding and the like when welding the air cylinder body 310 and the air cylinder head 320, improving the welding quality of the air cylinder body 310 and the air cylinder head 320, increasing the success rate of a successful welding of the air cylinder body 310 and the air cylinder head 320, and improving the welding efficiency of the air cylinder body 310 and the air cylinder head 320.

[0046] It is worth noting that the two support shafts 210 mentioned in the embodiment of the present application are arranged side by side and spaced apart, which means that the axes of the two support shafts 210 are parallel, and the two support shafts 210 are in a first direction (for example, Figure 1 The first direction is parallel to the axial direction of the support shaft 210.

[0047] In some embodiments of the present application, in order to facilitate the welding of the air cylinder barrel 310 and the air cylinder head 320, the axial length of the support shaft 210 is smaller than the axial length of the air cylinder barrel 310 of the air storage cylinder 300. This arrangement allows the ends of the air cylinder barrel 310 to extend out of the ends of the support shaft 210 when the air cylinder barrel 310 is placed on the support shaft 210, so that the joint between the air cylinder head 320 and the air cylinder barrel 310 is located outside the support shaft 210, which facilitates the welding of the air cylinder barrel 310 and the air cylinder head 320 by the operator.

[0048] Optionally, the axial length of the support shaft 210 is 300mm-500mm, and illustratively, the axial length of the support shaft 210 is 400mm. The axial length of the air cylinder barrel 310 is usually about 980mm, and the axial length of the support shaft 210 is 400mm, which can make the two ends of the air cylinder barrel 310 extend about 290mm from the two ends of the support shaft 210, respectively, and can leave enough operating space for operators. Of course, the air cylinder barrel 310 can have a larger length extending from the end of the support shaft 210 at one end, and a smaller length extending from the end of the support shaft 210 at the other end. The axial length of the support shaft 210 should not be too small or too large. If it is too small, the air cylinder barrel 310 docked with the air cylinder head 320 cannot be stably placed on the support shaft 210, and the air cylinder barrel 310 docked with the air cylinder head 320 may be placed unevenly when placed on the support shaft 210, and one end of the air storage cylinder 300 may extend too much from the support shaft 210, causing the air storage cylinder 300 to fall off the support shaft 210. If the axial length of the support shaft 210 is too large, when the air cylinder barrel 310 docked with the air cylinder head 320 is placed on the support shaft 210, one end of the air storage cylinder 300 may not extend from the support shaft 210, which is not conducive to the welding of the air cylinder barrel 310 and the air cylinder head 320.

[0049] In some embodiments of the present application, in order to enable the air cylinder barrel 310 docked with the air cylinder head 320 to rotate at a uniform speed on the two supporting shafts 210 to avoid slipping, the supporting shaft 210 includes a supporting portion and a connecting portion connected to both ends of the supporting portion, the two connecting portions are rotatably connected to the bracket 100 respectively, and the circumferential surface of the supporting portion is a rough surface. The air cylinder barrel 310 docked with the air cylinder head 320 is placed on the supporting portions of the two supporting shafts 210, and the rough surface of the supporting portion enables the air cylinder barrel 310 docked with the air cylinder head 320 to rotate at a uniform speed on the two supporting shafts 210 to avoid slipping.

[0050] Optionally, in order to prevent the support portion from rubbing against the air cylinder barrel 310 and damaging the air cylinder barrel 310, the support portion is covered with a rubber sleeve, which is a soft material and can protect the air cylinder barrel 310. Optionally, the outer surface of the rubber sleeve is a rough surface. Exemplarily, the outer surface of the rubber sleeve has criss-cross grooves, or the outer surface of the rubber sleeve has criss-cross raised strips, or the outer surface of the rubber sleeve has array-arranged raised points.

[0051] In the embodiment of the present application, the rotating support structure further includes four bearing seats 220, each bearing seat 220 is provided with a bearing, each bearing seat 220 is fixedly connected to the bracket 100, and is correspondingly arranged at both ends of the two supporting shafts 210. In other words, both ends of each supporting shaft 210 are respectively mounted on the bearing seat 220 through bearings, and the bearing seat 220 is fixedly connected to the bracket 100. This arrangement enables the supporting shaft 210 to rotate smoothly.

[0052] In order to enable the welder to perform welding work while sitting, the height of the bracket 100 is 230 mm-300 mm. Exemplarily, the height of the support frame is 250 mm. The height of the bracket 100 is relatively low, so that the height of the air storage cylinder 300 placed on the support shaft 210 is relatively low, thereby enabling the welder to perform welding work while sitting, reducing the labor intensity of the welder, and being able to place the air cylinder barrel 310 connected to the air cylinder head 320 on the support shaft 210 with relatively less effort, and being able to remove the welded air storage cylinder 300 from the support shaft 210 with relatively less effort.

[0053] Exemplarily, the vertical distance between the axis of the air storage cylinder 300 and the bottom of the bracket 100 is 450 mm-500 mm, thereby enabling the welder to perform welding work while sitting.

[0054] In some embodiments of the present application, in one of the rotating support structures, on the first cross section, the line between the contact point between the air storage cylinder 300 and one of the supporting shafts 210 and the center of the air storage cylinder 300 is the first line segment, and the line between the contact point between the air storage cylinder 300 and the other supporting shaft 210 and the center of the air storage cylinder 300 is the second line segment. The angle between the first line segment and the second line segment is 70°-90°, and illustratively, the angle between the first line segment and the second line segment is 80°. This arrangement enables the air storage cylinder 300 to be stably placed on the two supporting shafts 210, while enabling the supporting shafts 210 to drive the air storage cylinder 300 to rotate with less effort, thereby saving the output of the kinetic energy of the driving member. The first cross section is a plane perpendicular to the axial direction of the air storage cylinder 300.

[0055] In some embodiments of the present application, the bracket 100 includes two support beams 110 arranged opposite to each other, and a plurality of connecting beams 120 connecting the two support beams 110, and the plurality of connecting beams 120 are respectively arranged at both ends of the support beam 110 and between two adjacent rotating support structures. The connecting beam 120 is used to strengthen the stability of the connection between the two support beams 110. Each support beam 110 is provided with a plurality of supporting legs 130, and the number of supporting legs 130 on the two support beams 110 is the same and they are arranged opposite to each other. In the two opposite support legs 130, the two support legs 130 are connected by a connecting plate 140. The support legs 130 are used to support the two support beams 110.

[0056] Optionally, on one of the support beams 110, the number of the support legs 130 is the same as the number of the rotating support structures, and they correspond one to one. In the corresponding number of the support legs 130 and the rotating support structure, the support legs 130 are arranged between the two support shafts 210. This arrangement enables the support legs 130 to support the stress-bearing area of ​​the support beam 110, that is, the area where the air storage cylinder 300 is placed, thereby increasing the stability of the support beam 110.

[0057] Optionally, the connecting beam 120 and the connecting plate 140 are both angle steels.

[0058] In the embodiment of the present application, exemplarily, the number of rotating support structures is three, the number of connecting beams 120 is four, and the four connecting beams 120 are respectively arranged at both ends of the support beam 110 and between two adjacent rotating support structures. The number of support legs 130 is six, and three support legs 130 are correspondingly arranged on each support beam 110. On one of the support beams 110, the three support legs 130 are respectively arranged between the support shafts 210 of the three rotating support structures.

[0059] In order to make the welding quality of the air cylinder head 320 and the air cylinder barrel 310 uniform, the welding device of the industrial and mining electric locomotive air storage cylinder 300 also includes a welding robot, which is arranged on one side of the bracket 100. That is, the welding of the air cylinder head 320 and the air cylinder barrel 310 is welded by the welding robot.
