Description

Technical Field

[0001] This application relates to the technical field of brake beam production, and specifically to a composite assembly line for brake beam components. Background Art

[0002] As a core component of the railway freight car braking system, the quality of the brake beam directly determines the safety and stability of train operation. With the development of railway freight towards high speed and heavy load, the production of brake beams not only needs to meet the increasing output requirements but also ensure strict quality standards, which poses extremely high requirements for the efficiency and accuracy of the brake beam assembly line. In the brake beam assembly process, material conveying is a key link, and its conveying efficiency and stability have a decisive impact on the performance of the entire assembly line;

[0003] Chain conveyors are widely used in the field of material conveying due to their strong load-bearing capacity, stable operation, and high conveying accuracy. Introducing a chain conveyor into the brake beam assembly line can not only solve the problems of low efficiency, poor accuracy, and high labor intensity of traditional conveying methods but also be combined with automated assembly equipment to achieve full-process automation of brake beam assembly, greatly improving production efficiency and product quality.

[0004] In actual working conditions, the chain conveyor uses a conveying method where both ends of the brake beam are directly lapped on the chain. The brake beam itself has a large mass, causing the plate chain in contact with it to bear a great deal of pressure. During the conveying process, due to the pressure, the contact part between the chain plate and the pin shaft generates strong friction, resulting in increased wear; at the same time, when the chain is continuously running, it frequently rubs against and collides with the sprocket and other components. This not only affects the running stability of the chain conveyor but also generates a large amount of noise, causing certain interference to the working environment. Therefore, it is necessary to provide a composite assembly line for brake beam components to solve the above problems.

[0005] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

Detailed implementation manners

[0026] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0027] In order to enable those skilled in the art of this technology to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] As Figures 1-3 shown, the present application provides a composite assembly line for a brake beam, including a chain conveyor 1, the chain conveyor 1 having two sets of chains (not marked in the figure), and a support frame 11 for supporting the chain conveyor 1, and a brake beam body 12 is placed on the two sets of chains. The two ends of the brake beam body 12 have lapping parts 13. The two lapping parts 13 of the brake beam body 12 are respectively placed on the two sets of chains. After starting the chain conveyor 1, the chains start to rotate cyclically, and drive the brake beam body 12 to move synchronously by means of friction, thereby completing the conveying task of the brake beam on the assembly line;

[0029] And a lubrication assembly 2 is installed on the side of the support frame 11. The lubrication assembly 2 includes an installation box 21 fixedly installed on the side of the support frame 11, and a cylinder 22 is fixedly installed in the installation box 21. The telescopic end of the cylinder 22 penetrates through the installation box 21, and a support seat 23 is installed on the telescopic end of the cylinder 22, and a base 24 is fixedly installed on the support seat 23, and a storage tank 27 is installed on the base 24 by bolts. The storage tank 27 and the base 24 enclose a box structure for storing lubricating liquid;

[0030] And a discharge pipe 25 is fixedly installed through the base 24. The discharge pipe 25 is used to discharge the lubricating fluid. And a rotating shaft 28 is installed on the side of the storage tank 27 by bearings. A rotating part 29 is fixedly sleeved on the rotating shaft 28. At the same time, a sealing plug 210 is fixedly installed on the rotating part 29. The sealing plug 210 is adapted to rotate with the rotating shaft 28 to block the sealing plug 210 at the pipe orifice of the discharge pipe 25. It should be noted that, by default, the sealing plug 210 is perpendicular to the pipe orifice of the discharge pipe 25 to prevent the lubricating fluid from flowing out. Since the sealing plug 210 is made of a flexible material, when a torque is applied to the turntable 216, the turntable 216 drives the rotating shaft 28 to rotate 180°. The sealing plug 210 rotates with the rotating shaft 28 and moves to a position away from the discharge pipe 25, thereby opening the discharge channel, and the lubricating fluid can flow out through the discharge pipe 25;

[0031] And a turntable 216 is fixedly installed at one end of the rotating shaft 28. The turntable 216 is adapted to apply a torque to the rotating shaft 28 to drive the sealing plug 210 to rotate;

[0032] At the same time, a delivery pipe 26 is connected to one end of the discharge pipe 25. The delivery pipe 26 is a right-angle pipe. And a communicating pipe 211 is connected to the right-angle end of the delivery pipe 26. A plurality of through holes (not shown in the figure) are formed at the bottom of the communicating pipe 211. The through holes are adapted to allow the lubricating fluid to flow out. And a lubricating sponge 214 is movably sleeved on the communicating pipe 211. The lubricating sponge 214 has a sleeved part 215. The lubricating sponge 214 is movably sleeved on the communicating pipe 211 through the sleeved part 215. In the default state, the lubricating sponge 214 is set away from the chain, that is, the lubricating sponge 214 does not contact the chain first. At the same time, through holes corresponding to the positions of the through holes are also formed on the sleeved part 215. The through holes are adapted to deliver the lubricating fluid flowing out through the through holes into the lubricating sponge 214 to wet and fill the lubricating sponge 214 with the lubricating fluid. And in the initial state, the positions of the through holes on the sleeved part 215 are away from the through holes, that is, when the sleeved part 215 rotates 180 degrees, the through holes correspond to the through holes at this time;

[0033] And it should be noted that a first limiting part (not marked in the figure) is fixedly installed at the right-angle end of the delivery pipe 26. At the same time, a second limiting part (not marked in the figure) is fixedly installed at one end of the communicating pipe 211. When the lubricating sponge 214 is sleeved on the communicating pipe 211 through the sleeved part 215, there is a certain gap between the two ends of the sleeved part 215 and the first limiting part and the second limiting part respectively, so that when the sleeved part 215 rotates 180 degrees, the through holes can correspond to the through holes;

[0034] And a cleaning brush 212 is movably sleeved on the connecting pipe 211. The cleaning brush 212 has two sets of socket rings 213, and the two sets of socket rings 213 are respectively sleeved at the gaps between the two ends of the socket part 215 and the first limiting part and the second limiting part. At the same time, an arc-shaped groove (not marked in the figure) corresponding to the socket part 215 is provided on the cleaning brush 212. It should be noted that in the initial state, the cleaning brush 212 is arranged close to the chain, and the cleaning brush 212 corresponds to the lubricating sponge 214, and the cleaning brush 212 and the lubricating sponge 214 rotate 180 degrees to switch positions;

[0035] In the initial stage, the cleaning brush 212 is close to the chain, and the lubricating sponge 214 is far from the chain. When cleaning work needs to be carried out, the air cylinder 22 pushes the storage box 27 close to the chain conveyor 1. At this time, the cleaning brush 212 approaches and adheres to the chain. As the chain conveyor 1 operates, the cleaning brush 212 wipes the running chain to remove dust, oil stains and impurities attached to the surface of the chain, preparing for the subsequent lubrication process.

[0036] After the cleaning work is completed, the lubricating sponge 214 needs to be filled with liquid. Rotate the turntable 216 to open the discharge pipe 25, and the lubricating liquid then flows from the discharge pipe 25 into the conveying pipe 26. Since the conveying pipe 26 is a right-angle pipe, the lubricating liquid changes its flow direction and enters the connecting pipe 211. In the initial state, the through holes on the socket part 215 and the through holes at the bottom of the connecting pipe 211 are staggered in position. With the help of manual or automated devices, rotate the socket part 215 of the lubricating sponge 214 by 180°. Due to the gap limitations between the two ends of the socket part 215 and the first limiting part and the second limiting part, the through holes and the through holes can be accurately aligned. At this time, the lubricating liquid flows into the lubricating sponge 214 through the through holes and the through holes, wetting it and filling it with lubricating liquid.

[0037] To drive the cleaning brush 212 and the lubricating sponge 214 to switch positions, as Figures 2-3 shown, a driving component 3 is installed on the rotating shaft 28. The driving component 3 includes a first bevel gear 31 fixedly installed on the rotating shaft 28, and a second bevel gear 32 meshed with the first bevel gear 31. At the same time, a bracket 35 is fixedly installed on the mounting box 21. The bracket 35 is approximately in the shape of a "Z", and a connecting shaft 33 is fixedly installed on the side of the bracket 35. One end of the connecting shaft 33 is installed with a rotating rod (not marked in the figure) by means of a bearing, and the second bevel gear 32 is fixedly installed on the rotating rod;

[0038] A first rack 36 is slidably mounted on the bracket 35. At the same time, a first sliding groove (not shown in the figure) adapted to the width of the first rack 36 is formed in the bracket 35. A first gear 34 is fixedly mounted on the rotating rod. The first gear 34 meshes with the first rack 36. A second rack 37 is slidably mounted on the bracket 35. The second rack 37 is connected to the first rack 36. At the same time, a second sliding groove (not shown in the figure) adapted to the width of the second rack 37 is formed in the bracket 35. A second gear 38 is mounted on one end of the connecting pipe 211 by means of a bearing. The second gear 38 has a smooth section (not marked in the figure). In the initial state, the second gear 38 is in the position of the smooth section;

[0039] It should be noted that the socket part 215 and a set of socket rings 213 are fixedly connected to the side surface of the second gear 38. When the chain needs to be lubricated, the cylinder 22 is started to drive the cleaning brush 212 to approach and contact the chain. At this time, as the chain moves, the cleaning brush 212 can clean the surface of the chain. After the cleaning is completed, the rotating shaft 28 is driven to rotate by holding the turntable 216 until the sealing plug 210 is disengaged from the nozzle of the discharge pipe 25. At this time, the lubricating oil enters through the nozzle of the discharge pipe 25 and sequentially enters the conveying pipe 26 and the connecting pipe 211. Since the cleaning brush 212 is in the position close to the chain at this time, the socket part 215 can block the through holes on the connecting pipe 211. In this application, a flexible protrusion for initially sealing and blocking multiple groups of through holes can be provided in the socket part 215, and the protrusion can be made of silica gel material;

[0040] As the rotating shaft 28 rotates, the first bevel gear 31 is driven to rotate. The first bevel gear 31 drives the second bevel gear 32 to rotate. The second bevel gear 32 drives the rotating rod to rotate. The rotating rod drives the first gear 34 to rotate. As the first gear 34 rotates, the first rack 36 is driven to move linearly. Since the second gear 38 is in the position of the smooth section at this time, the second gear 38 does not rotate during the initial movement of the first rack 36. When the rotating shaft 28 rotates 90 degrees, the lubricating oil in the storage tank 27 is discharged through the discharge pipe 25 and enters the connecting pipe 211. Then when the rotating shaft 28 rotates 180 degrees, the first rack 36 drives the second rack 37 to approach the second gear 38. When the second gear 38 is driven to rotate 180 degrees, the position switching between the cleaning brush 212 and the lubricating sponge 214 is completed.

[0041] To sum up:

[0042] S1. Brake beam conveying

[0043] Start the chain conveyor 1, and the two groups of chains start to rotate cyclically. The lapping parts 13 at both ends of the brake beam body 12 are respectively placed on the two groups of chains, and the chains drive the brake beam body 12 to move synchronously by means of friction, thus completing the conveying task of the brake beam on the assembly line.

[0044] S2. Cleaning preparation and operation

[0045] When it is necessary to clean the chains, start the cylinder 22 in the installation box 21. The telescopic end of the cylinder 22 pushes the support seat 23, the base 24 and the storage box 27 close to the chain conveyor 1. At this time, the cleaning brush 212 that is close to the chains in the initial state gets closer to and fits the chains. With the operation of the chain conveyor 1, the cleaning brush 212 wipes the running chains, removing the dust, oil stains and impurities on the chain surfaces, and preparing for the subsequent lubrication process.

[0046] S3. Liquid filling preparation for the lubricating sponge 214

[0047] After the chain cleaning work is completed, rotate the turntable 216 installed at one end of the rotating shaft 28, driving the rotating shaft 28 to rotate, so that the sealing plug 210 fixed on the rotating shaft 28 rotates 180°, changing from the sealed state perpendicular to the nozzle of the discharge pipe 25 to the open state away from the nozzle of the discharge pipe 25. At this time, the lubricating liquid in the storage box 27 flows into the delivery pipe 26 through the discharge pipe 25. Since the delivery pipe 26 is a right-angle pipe, the lubricating liquid changes its flow direction and then enters the connecting pipe 211.

[0048] S4. Position switching drive preparation

[0049] To realize the position switching between the cleaning brush 212 and the lubricating sponge 214, rotate the turntable 216 to drive the rotating shaft 28 to rotate, and the first bevel gear 31 fixed on the rotating shaft 28 rotates accordingly. The first bevel gear 31 meshes with the second bevel gear 32, causing the second bevel gear 32 to rotate, and then driving the rotating rod to rotate around the connecting shaft 33, and the first gear 34 on the rotating rod also rotates synchronously.

[0050] S5. Preliminary transmission for position switching

[0051] In the initial stage of the rotation of the first gear 34, since the second gear 38 is initially in the smooth section position, the first rack 36 moves linearly driven by the first gear 34, but the second gear 38 does not rotate at this time. As the rotating shaft 28 rotates 90°, the sealing plug 210 completely opens the discharge channel, and the lubricating liquid smoothly flows into the connecting pipe 211.

[0052] S6. Position switching between the cleaning brush 212 and the lubricating sponge 214

[0053] When the rotating shaft 28 continues to rotate to 180°, the first gear 34 continues to rotate, driving the first rack 36 to move further linearly. Since the first rack 36 is connected to the second rack 37, the movement of the first rack 36 drives the second rack 37 closer to the second gear 38. The second rack 37 interacts with the second gear 38, driving the second gear 38 to rotate 180°. Because the socket part 215 and a set of socket rings 213 are fixedly connected to the side of the second gear 38, the rotation of the second gear 38 causes the cleaning brush 212 and the lubricating sponge 214 to complete a 180° position switch. The lubricating sponge 214 approaches the chain and starts lubricating, and the cleaning brush 212 moves to a position away from the chain to wait for the next cleaning task.

[0054] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
