Description

Technical Field

[0001] This utility model relates to the field of flash welding machine technology, and more specifically, to a turnout flash welding machine with the upsetting and pushing cylinders on the same side. Background Technology

[0002] When welding rails in turnout sections, flash welding is usually used. However, three issues need to be addressed during welding: firstly, welding wide-spacing standard rails, as follows... Figure 1 The welding of rails at positions 1 and 2 can be completed using a traditional welding machine; the second is the welding of ordinary standard rails with narrow spacing within 150mm to 200mm, such as... Figure 1 For sections 4, 5, and 6, this part can be welded using a narrow-jaw flash welding machine (or turnout welding machine). Simultaneously, the turnout welding machine must be compatible with welding wide-spacing standard rails. Thirdly, welding of variable cross-section AT rails to standard rails, such as... Figure 2 The diagram shown is a structural schematic of a variable cross-section AT rail. Figure 1 The right ends of the variable cross-section AT rails at points 4, 6, and 12 are welded to ordinary rails. At the same time, the turnout welding machine is required to be compatible with welding ordinary standard rails with wide and narrow spacing. Only in this way can the flash welding of all rails in the turnout section be completely solved, and the overall level of welding quality of my country's railway lines be greatly improved.

[0003] Traditional mobile rail flash welding machines with pressure-holding and push-convex functions are characterized by having the forging cylinder and push-convex cylinder located on opposite sides of the welding machine. A typical structure is disclosed in Chinese Patent Application No. 2017109824814. However, the traditional welding machine's structure is limited by the proximity of the rails in turnout sections, resulting in a significant portion of the rails being unweldable. To address this issue, turnout flash welding machines have seen rapid development in recent years. For example, Chinese Patent Application No. 2024114021011 uses a narrow jaw design to solve some of the turnout rail welding problems. However, some special-shaped rails specifically designed for turnouts still cannot be welded, such as variable cross-section AT rails. Figure 2 As shown, the characteristics of this type of rail are: one end is a standard 60kg / m rail with a normal cross section, and after a certain length, the cross section of the rail gradually changes into an asymmetrical AT rail cross section. This change makes it impossible for existing flash welding machines to weld the variable cross section AT rails specifically for turnouts. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a turnout flash welding machine with the upsetting and pushing cylinders on the same side, so as to ensure that the flash welding machine can also weld the variable cross-section AT rails for turnouts, thereby improving the applicability of the flash welding machine.

[0005] To achieve the above objectives, this utility model provides a turnout flash welding machine with the upsetting and pushing cylinders on the same side, including an upsetting mechanism, a pushing mechanism, a moving frame assembly and a stationary frame assembly arranged opposite to each other, wherein: the stationary frame assembly is used to clamp a first rail, and the moving frame assembly is used to clamp a second rail; the upsetting mechanism includes an upsetting cylinder and an upsetting shaft, the upsetting cylinder includes an upsetting cylinder body and an upsetting piston rod drivenly connected to the upsetting cylinder body, the upsetting cylinder body is installed on the stationary frame assembly on the side away from the moving frame assembly, the upsetting piston rod is slidably disposed on the stationary frame assembly, the extension and retraction path of the upsetting piston rod is parallel to the length direction of the first rail, and one end of the upsetting shaft is installed on the moving frame assembly near the stationary frame assembly. On one side of the frame assembly, the other end of the forging shaft is mounted on the forging piston rod at the end away from the forging cylinder body. The extension and retraction of the forging piston rod drives the forging shaft and the moving frame assembly to reciprocate. The pushing mechanism includes a pushing cylinder and a pushing cutter. The pushing cylinder includes a pushing cylinder body and a pushing piston rod drivenly connected to the pushing cylinder body. The pushing cylinder body is mounted on the stationary frame assembly at the side away from the moving frame assembly. The pushing piston rod is slidably mounted on the stationary frame assembly. The extension and retraction path of the pushing piston rod is parallel to the length direction of the first rail. The pushing cutter is mounted on the pushing piston rod at the end away from the pushing cylinder body. The pushing cutter is located between the stationary frame assembly and the moving frame assembly.

[0006] Optionally, the forging cylinder is located above the pushing cylinder.

[0007] Optionally, the central axis of the push-out cylinder is located on the same horizontal plane as the neutral line of the first rail.

[0009] Optionally, a sliding sleeve matching the upsetting shaft is provided on the side of the stationary frame assembly near the moving frame assembly, and the upsetting shaft is slidably disposed within the sliding sleeve.

[0010] Optionally, an auxiliary mechanism is also included, which includes an auxiliary shaft and a sleeve used in conjunction with the auxiliary shaft.

[0012] Optionally, there are two upsetting mechanisms, which are located on both sides of the first rail.

[0014] The present invention provides a turnout flash welding machine with the upsetting and pushing cylinders on the same side, including an upsetting mechanism, a pushing mechanism, a moving frame assembly and a stationary frame assembly arranged opposite to each other. The upsetting cylinder and the pushing cylinder are set on the same side of the stationary frame assembly. When the second rail is a variable cross-section AT rail for turnouts, the side of the moving frame assembly is free from the interference of the upsetting cylinder and the pushing cylinder, which makes it easier to observe the clamping effect of the variable cross-section AT rail. This ensures that the flash welding machine can also weld variable cross-section AT rails for turnouts, thus improving the applicability of the flash welding machine. Attached Figure Description

[0023] like Figure 3 As shown, the turnout flash welding machine with the upsetting and pushing cylinders on the same side provided by this utility model includes an upsetting mechanism 1, a pushing mechanism 2, a moving frame assembly 3 and a stationary frame assembly 4 arranged opposite to each other, wherein: the stationary frame assembly 4 is used to clamp the first rail 12, and the moving frame assembly 3 is used to clamp the second rail 13; the upsetting mechanism 1 includes an upsetting cylinder 5 and an upsetting shaft 6, the upsetting cylinder 5 includes an upsetting cylinder body and an upsetting piston rod drivenly connected to the upsetting cylinder body, the upsetting cylinder body is installed on the stationary frame assembly 4 on the side away from the moving frame assembly 3, the upsetting piston rod is slidably arranged on the stationary frame assembly 4, the extension and retraction path of the upsetting piston rod is parallel to the length direction of the first rail 12, and one end of the upsetting shaft 6 is installed on the moving frame assembly 4. On the side of the frame assembly 3 near the stationary frame assembly 4, the other end of the forging shaft 6 is installed on the forging piston rod at the end away from the forging cylinder body.

The pushing cylinder body is installed on the side of the stationary frame assembly 4 away from the moving frame assembly 3. The pushing piston rod is slidably arranged on the stationary frame assembly 4. The extension and retraction path of the pushing piston rod is parallel to the length direction of the first rail 12. The pushing knife is installed on the pushing piston rod at the end away from the pushing cylinder body. The pushing knife is located between the stationary frame assembly 4 and the moving frame assembly 3.

[0024] It should be noted that the first rail 12 is a regular rail, and the second rail 13 can be a regular rail or a variable cross-section AT rail.

[0025] The present invention provides a turnout flash welding machine with the upsetting and pushing cylinders on the same side, including an upsetting mechanism 1, a pushing mechanism 2, a moving frame assembly 3 and a stationary frame assembly 4 arranged opposite to each other. The upsetting cylinder and the pushing cylinder are set on the same side of the stationary frame assembly 4. When the second rail 13 is a variable cross-section AT rail for turnouts, the side of the moving frame assembly 3 is free from the interference of the upsetting cylinder and the pushing cylinder, which makes it easier to observe the clamping effect of the variable cross-section AT rail. This ensures that the flash welding machine can also weld variable cross-section AT rails for turnouts, thus improving the applicability of the flash welding machine.

[0026] like Figure 3 As shown, the upsetting cylinder 5 is located above the push-forging cylinder 7. In this embodiment, the upsetting cylinder 5 and the push-forging cylinder 7 are staggered vertically to provide installation space for the electrodes and the busbar of the upsetting shaft 6 required for welding. This enables welding of variable cross-section AT rails and improves the applicability of the turnout flash welding machine on the same side as the upsetting and push-forging cylinders.

[0027] like Figure 4As shown, the central axis of the push-forward cylinder is on the same horizontal plane as the neutral line 8 of the first rail 12. In this embodiment, the central axis of the push-forward cylinder is on the same horizontal plane as the neutral line 8 of the first rail 12 so that the push-forward mechanism 2 can achieve force balance between the rail head and the rail bottom during operation, avoid jamming during the push-forward operation, and improve the structural stability of the turnout flash welding machine on the same side as the upsetting and push-forward cylinders.

[0028] like Figure 3 As shown, a first baffle 9 is provided on the side of the moving frame assembly 3 near the stationary frame assembly 4 to prevent welding slag from splashing onto the upsetting shaft 6. In this embodiment, since welding slag and other materials will splash out during rail welding, the first baffle 9 can prevent welding slag from splashing onto the upsetting shaft 6, thus improving the ease of use of the turnout flash welding machine on the same side as the upsetting and push cylinders.

[0029] In one embodiment of this utility model, a sliding sleeve matching the upsetting shaft 6 is provided on the side of the stationary frame assembly 4 near the moving frame assembly 3. The upsetting shaft 6 is slidably disposed in the sliding sleeve. The sliding sleeve enables the upsetting shaft 6 to be slidably disposed on the stationary frame assembly 4, thereby improving the structural stability of the turnout flash welding machine on the same side as the upsetting and push cylinders.

[0030] like Figure 3 As shown, it also includes an auxiliary mechanism, which includes an auxiliary shaft 11 and a sleeve used in conjunction with the auxiliary shaft 11. The auxiliary shaft 11 is mounted on the moving frame assembly 3 near the stationary frame assembly 4. The moving frame assembly 3 is slidably disposed along the axial direction of the auxiliary shaft 11. The sleeve is mounted on the stationary frame assembly 4 near the moving frame assembly 3, and the auxiliary shaft 11 is slidably disposed within the sleeve. In this embodiment, the auxiliary mechanism can counteract the additional bending moment caused by the upsetting cylinder 5 during upsetting, thereby improving the structural stability of the turnout flash welding machine on the same side as the upsetting and push cylinders.

[0031] like Figure 3 As shown, a second baffle 10 is provided on the side of the moving frame assembly 3 near the stationary frame assembly 4 to prevent welding slag from splashing onto the auxiliary shaft 11. In this embodiment, welding slag and other materials will splash out during rail welding. The second baffle 10 can prevent welding slag from splashing onto the auxiliary shaft 11, improving the ease of use of the turnout flash welding machine on the same side as the upsetting and push cylinders.

[0032] like Figure 3 As shown, there are two upsetting mechanisms 1, which are located on both sides of the first rail 12. In this embodiment, the two upsetting mechanisms 1 can increase the upsetting strength. Moreover, the two upsetting mechanisms 1 are located on both sides of the first rail 12, which can ensure that the force is more uniform during upsetting, thereby improving the structural stability of the turnout flash welding machine on the same side as the upsetting and push cylinder.

[0033] like Figure 3As shown, there are two pushing mechanisms 2, which are located on both sides of the first rail 12. In this embodiment, the two pushing mechanisms 2 can increase the pushing speed, and the two pushing mechanisms 2 are located on both sides of the first rail 12, which can ensure that the force is more uniform during pushing, thus improving the structural stability of the turnout flash welding machine on the same side as the upsetting and pushing cylinders.

[0034] The present invention provides a turnout flash welding machine with the upsetting and pushing cylinders on the same side, including an upsetting mechanism 1, a pushing mechanism 2, a moving frame assembly 3 and a stationary frame assembly 4 arranged opposite to each other. The upsetting cylinder and the pushing cylinder are set on the same side of the stationary frame assembly 4. When the second rail 13 is a variable cross-section AT rail for turnouts, the side of the moving frame assembly 3 is free from the interference of the upsetting cylinder and the pushing cylinder, which makes it easier to observe the clamping effect of the variable cross-section AT rail. This ensures that the flash welding machine can also weld variable cross-section AT rails for turnouts, thus improving the applicability of the flash welding machine.
