Description

Technical Field

[0001] This utility model relates to the field of track welding equipment technology, and in particular to a slag removal mechanism for track welding machines. Background Technology

[0002] In modern railway construction and maintenance, seamless welding of rails is a crucial process to ensure the smooth and safe operation of trains. After the rails are welded, it is inevitable that excess weld slag and burrs will form at the joint.

[0003] To ensure the smoothness of the track, these weld slags must be removed promptly. Existing track welding machines typically integrate a slag removal mechanism, which mainly relies on scrapers to mechanically shear or scrape the weld slag before the weld has fully cooled, separating it from the rail base material.

[0004] However, existing slag removal mechanisms reveal a core problem of poor structural adaptability in practical applications. On the one hand, railway tracks come in various models and specifications, with differences in rail head width or rail web groove dimensions. Traditional slag removal mechanisms are typically equipped with fixed-size scrapers, limiting their operation to a specific type of rail.

[0005] When different specifications of rails need to be processed on the construction site, it is necessary to replace the entire slag removal mechanism or carry multiple different models of equipment. This not only greatly increases the procurement and storage costs of equipment, but also seriously reduces the flexibility and efficiency of on-site operations. On the other hand, the above problems are further exacerbated by the wear-prone nature of the scraper. As a component that directly experiences strong friction and shearing with high-temperature weld slag, the scraper's cutting edge wears very quickly, making it a high-consumption component that requires frequent online replacement.

[0006] Therefore, this utility model proposes a slag removal mechanism for a track welding machine to address the shortcomings of existing technologies. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a slag removal mechanism for a track welding machine, which aims to improve the technical problems of existing slag removal mechanisms having a simple structure, being unable to adapt to different track specifications, and having a cumbersome and inefficient scraper replacement process.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a slag removal mechanism for a track welding machine, comprising: a slag removal assembly, the slag removal assembly comprising a second connecting frame and a first scraper mounted on the second connecting frame, the slag removal assembly further comprising a second scraper, a fixing bolt and a quick-release assembly, the second scraper being provided with a second T-shaped slider, the first scraper having a guide groove adapted to the second T-shaped slider, the second T-shaped slider being slidably connected to the guide groove of the first scraper, and the fixing bolt being used to fix the position of the second scraper, thereby achieving adjustable scraping width;

[0009] The quick-connect assembly is used to detachably connect the first scraper to the second connecting frame. The quick-connect assembly includes a first connecting block, a second connecting block, a fixed shell, a first transmission column, a pressing column, a support plate, a fixing ring, a spring, a connecting ring, a second transmission column, a retaining ball, and a T-shaped groove, all fixedly connected to the first scraper.

[0010] The fixed shell is fixed to the second connecting frame. The first connecting block is slidably sleeved on the outer wall of the fixed shell. A retaining ball is disposed between the first connecting block and the fixed shell. The second transmission column is slidably disposed inside the fixed shell, and a T-shaped groove is formed on the outer surface of the second transmission column. The pressing column passes through the fixed shell and forms a transmission connection with the second transmission column, used to drive the second transmission column to move axially, so that the T-shaped groove selectively aligns with or offsets the position of the retaining ball. The axial movement of the pressing column, through precise control of the position of the T-shaped groove, realizes the locking and releasing of the retaining ball, thereby realizing the quick assembly and disassembly of the first scraper.

[0011] Preferably, the pressing column is fixedly connected to the first transmission column, the first transmission column is fixedly connected to the second transmission column, and the connecting ring is slidably connected inside the fixed shell and sleeved at the connection between the first transmission column and the second transmission column.

[0012] Preferably, the quick-release assembly further includes a spring and a retaining ring. The retaining ring is fixed inside the retaining housing, and the spring is disposed between the connecting ring and the retaining ring. The spring is used to provide a reset force so that the pressing post can automatically return to the locked position after release.

[0013] Preferably, the quick-installation assembly further includes a second connecting block, which is slidably connected to the inner wall of the fixed shell, and the connecting ring is slidably connected to the interior of the second connecting block.

[0014] Preferably, the quick-assembly assembly further includes a support plate, which is fixed to the outer wall of the fixed shell to facilitate the worker's grip and application of force.

[0015] Preferably, the slag removal assembly further includes a first connecting frame connected to the welding machine, and an electric telescopic rod connected between the first connecting frame and the second connecting frame.

[0016] Preferably, the slag removal assembly further includes a fixing block fixedly connected to the second connecting frame, and a first T-shaped slider fixedly connected to the first scraper. The first T-shaped slider is slidably connected inside the fixing block to ensure smooth lateral movement of the second connecting frame under the drive of the electric telescopic rod.

[0017] Preferably, the fixing bolt passes through the first scraper and is screwed onto the second T-shaped slider, so that the fixing bolt can directly act on the second T-shaped slider to achieve reliable locking of the second scraper.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model solves the problem of poor versatility of existing welding slag removal mechanisms by setting a first scraper and a second scraper that can be slidably connected inside the first scraper, and locking the adjusted second scraper with fixing bolts. It achieves the effect of flexibly adjusting the total length of the scraper, multi-purpose machine, strong applicability, and reduced equipment cost.

[0020] 2. This utility model, by setting a quick-installation component, uses a pressing column to drive the internal second transmission column to move axially, so that the T-shaped groove on the second transmission column is selectively aligned with the locking ball, thereby realizing the locking and releasing of the locking ball. This solves the problems of the existing scraper being a wear part, which is cumbersome to replace, requires special tools, is time-consuming and labor-intensive, and has low maintenance efficiency. It achieves the effect of quick disassembly and installation of scraper without tools, convenient operation, shortened maintenance time, and improved on-site construction efficiency.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-6 The present invention provides an embodiment of a slag removal mechanism for a track welding machine, comprising a slag removal assembly 2. The slag removal assembly 2 includes a first connecting frame 201 connected to the welding machine 1, an electric telescopic rod 202, a second connecting frame 203, a fixing block 204, a first T-shaped slider 205, a first scraper 206, a second scraper 207, a fixing bolt 208, and a second T-shaped slider 209. The slag removal assembly 2 also includes a quick-installation assembly 3 for quickly assembling and disassembling the first scraper 206.

[0031] Specifically, the first connecting frame 201 is used to fix it on the welding machine 1, one end of the electric telescopic rod 202 is connected to the first connecting frame 201, the other end of the electric telescopic rod 202 is connected to the second connecting frame 203, the fixing block 204 is fixedly connected to the second connecting frame 203, the first scraper 206 is detachably connected to the second connecting frame 203 through the quick-release assembly 3, the first T-shaped slider 205 is fixedly connected to the first scraper 206, and the first T-shaped slider 205 is slidably connected to the inside of the fixing block 204;

[0032] The first scraper 206 and the second scraper 207 together constitute a retractable scraping structure. The second scraper 207 is provided with a second T-shaped slider 209. The first scraper 206 has a guide groove adapted to the second T-shaped slider 209. The second T-shaped slider 209 is slidably connected in the guide groove of the first scraper 206. Through this sliding fit, the relative position of the first scraper 206 and the second scraper 207 can be adjusted, thereby changing the overall scraping width. The fixing bolt 208 passes through the first scraper 206 and is screwed onto the second T-shaped slider 209 to lock and fix the adjusted second scraper 207 relative to the first scraper 206.

[0033] The quick-installation assembly 3 includes a first connecting block 301, a second connecting block 302, a fixed shell 303, a first transmission column 304, a pressing column 305, a support plate 306, a fixing ring 307, a spring 308, a connecting ring 309, a second transmission column 310, a retaining ball 311, and a T-shaped groove 312, all fixedly connected to the first scraper 206. The fixed shell 303 is fixed to the second connecting frame 203 and serves as the mounting base for the quick-installation assembly 3. The first connecting block 301 is slidably sleeved on the outer wall of the fixed shell 303. The retaining ball 311 is located between the first connecting block 301 and the fixed shell 303. Specifically, the first connecting block 301 has a through hole for the retaining ball 311 to pass through, allowing the retaining ball 311 to move radially. The second transmission column 310 is slidably disposed inside the fixed shell 303, and its outer surface has a T-shaped groove. The T-shaped groove 312 is key to locking and unlocking. The pressing post 305 passes through the fixed shell 303 and forms a transmission connection with the second transmission post 310. By pressing the pressing post 305, the second transmission post 310 can be driven to move axially, thereby controlling the T-shaped groove 312 to selectively move to the inside of the locking ball 311 or to be offset from the inside of the locking ball 311. When the T-shaped groove 312 moves to the inside of the locking ball 311, it provides space for the locking ball 311 to move inward. At this time, the first connecting block 301 can be detached from the fixed shell 303. When the T-shaped groove 312 is offset from the locking ball 311, the outer wall of the second transmission post 310 abuts against the locking ball 311, preventing the locking ball 311 from moving inward, thereby locking the first connecting block 301 onto the fixed shell 303.

[0034] The pressing column 305 is fixedly connected to the first transmission column 304, and the first transmission column 304 is fixedly connected to the second transmission column 310. Thus, the pressing column 305, the first transmission column 304, and the second transmission column 310 constitute a rigid transmission assembly. When the pressing column 305 is subjected to force, it synchronously performs axial reciprocating motion. The connecting ring 309 is slidably connected inside the fixed shell 303, and the connecting ring 309 is sleeved at the connection between the first transmission column 304 and the second transmission column 310. When the transmission assembly moves axially, the transmission... The moving part drives the connecting ring 309 to slide synchronously. The fixed ring 307 is fixed inside the fixed shell 303 and is used to provide a fixed support end for the spring 308. The spring 308 is located between the connecting ring 309 and the fixed ring 307. In the static state, the spring 308 is in a naturally extended or pre-compressed state, pushing the connecting ring 309 and the entire transmission part to the initial position. When the pressing column 305 is pressed inward, the connecting ring 309 will move towards the fixed ring 307, thereby compressing the spring 308.

[0035] Meanwhile, the axial movement of the second transmission column 310 and the positional relationship of the locking ball 311 form a locking and unlocking engagement. In the assembled state, the locking ball 311 is partially accommodated in the through hole of the first connecting block 301 and partially extends out to engage in the annular groove opened in the inner wall of the fixing shell 303. In the locked state without pressing the pressing column 305, the outer peripheral surface of the second transmission column 310 is located inside the locking ball 311, abutting against the locking ball 311 and preventing the locking ball 311 from moving radially inward, thereby reliably locking the first connecting block 301 in the fixing shell 303. 3. When the pressing post 305 is pressed, the second transmission post 310 moves inward, so that the T-shaped groove 312 on the second transmission post 310 moves exactly to the inner position of the retaining ball 311. At this time, the T-shaped groove 312 provides a space for the retaining ball 311 to retract inward. When the first connecting block 301 is pulled outward, the retaining ball 311 will retract into the T-shaped groove 312, thereby disengaging from the annular groove on the inner wall of the fixed shell 303, realizing the separation of the first connecting block 301 from the fixed shell 303, ensuring the reliability of the connection and the convenience of disassembly and assembly.

[0036] For the electric telescopic rod 202 used to drive the second connecting frame 203 to achieve the fitting action, those skilled in the art can use a variety of conventional linear actuators such as electric push rods, hydraulic cylinders or pneumatic cylinders commonly available on the market. The specific internal structure of the electric telescopic rod 202 is a well-known technology in the field and will not be described in detail here.

[0037] To achieve stable transmission and automatic reset of the pressing column 305, the internal structure of the quick-release assembly 3 is further optimized. The pressing column 305 is fixedly connected to the first transmission column 304, the first transmission column 304 is fixedly connected to the second transmission column 310, and the connecting ring 309 is slidably connected to the inner wall of the fixed shell 303, and the connecting ring 309 is sleeved at the connection between the first transmission column 304 and the second transmission column 310. The quick-release assembly 3 also includes a spring 308 and a fixing ring 307. The fixing ring 307 is fixed inside the fixed shell 303, and the spring 308 is disposed between the connecting ring 309 and the fixing ring 307. The quick-release assembly 3 also includes a second connecting block 302, which is slidably connected to the inner wall of the fixed shell 303, and the connecting ring 309 is slidably connected inside the second connecting block 302.

[0038] To facilitate gripping and applying force by staff, the quick-assembly assembly 3 also includes a support plate 306, which is fixed to the outer wall of the fixed housing 303. To enable the slag removal assembly 2 to automatically conform to the track surface, the slag removal assembly 2 also includes a first connecting frame 201 connected to the welding machine 1, and an electric telescopic rod 202 connected between the first connecting frame 201 and the second connecting frame 203. To ensure that the second connecting frame 203 can move smoothly laterally when the electric telescopic rod 202 is driven, the slag removal assembly 2 also includes a fixing block 204 fixedly connected to the second connecting frame 203, and a first T-shaped slider 205 fixedly connected to the first scraper 206. The first T-shaped slider 205 is slidably connected to the inside of the fixing block 204. To reliably lock the extension length of the second scraper 207, the fixing bolt 208 is specifically connected by passing through the first scraper 206 and screwing onto the second T-shaped slider 209.

[0039] Working principle: After the welding machine 1 completes the welding and cooling process of the track, the burrs at the weld joint need to be removed by the slag removal assembly 2. Before the slag removal operation begins, the length of the scraper needs to be adjusted according to the track size. The worker pushes the second scraper 207 on both sides to slide inwards in the opposite direction, so that the second T-shaped slider 209 slides inside the guide groove of the first scraper 206. When the total length of the first scraper 206 and the second scraper 207 combined is the same as the length of the grooves on both sides of the track, the operator uses the fixing bolt 208 to lock the position of the second scraper 207, completing the length adjustment. Then, the drive... The electric telescopic rod 202, which is connected to the first connecting frame 201, moves outward at its output end, pushing the second connecting frames 203 on both sides to move outward in the opposite direction. During the movement, the first T-shaped slider 205, which is fixed on the first scraper 206, slides inside the fixed block 204, so that the first scraper 206 and the second scraper 207 can fully fit with the groove surfaces on both sides of the track. Finally, the drive component outside the welding machine 1 is started to push the already fitted first scraper 206 and the second scraper 207 to slide on the groove surfaces on both sides of the track, thereby removing the burrs at the welding point.

[0040] When the first scraper 206 and the second scraper 207 are severely worn and need to be disassembled and replaced, the worker holds the support plate 306 of the quick-release assembly 3 and pushes the pressing column 305 inward. The pressing column 305 drives the first transmission column 304 and the second transmission column 310 to move inward, while simultaneously causing the connecting ring 309 to slide on the inner wall of the fixing shell 303 inside the second connecting block 302, thereby compressing the spring 308 located on one side of the fixing ring 307. During the inward movement of the second transmission column 310, the T-shaped groove 312 on the outer surface of the second transmission column 310 will move to the inner side of the retaining ball 311, providing space for the retaining ball 311 to move inward. Next, the worker pulls the first scraper 206 outward. The first connecting block 301 slides on the outer wall of the fixed shell 303. The first connecting block 301 pushes the ball 311 inward and into the interior of the T-shaped groove 312, realizing the rapid separation of the first scraper 206 and the second scraper 207 together with the first connecting block 301 from the fixed shell 303. When installing a new scraper, the new first connecting block 301 is aligned with the fixed shell 303 and pushed in. Then the pressing column 305 is released. Under the elastic force of the spring 308, the connecting ring 309 is pushed back, driving the second transmission column 310 to reset. The outer wall of the second transmission column 310 squeezes the ball 311 out of the T-shaped groove 312 and makes it engage with the groove inside the first connecting block 301, thereby completing the installation and fixing of the new scraper.
