Description

Technical Field

[0001] The invention belongs to the technical field of track operation equipment, in particular to a rubber pad pre-installation operation device suitable for new sleepers and a sleeper replacement method. Background Art

[0002] After a certain number of years of use or damage, railway tracks usually need to be replaced with new sleepers. The operation of laying new sleepers usually requires first removing the rails and the old sleepers, then laying the new sleepers at the preset positions, and then setting rubber pads where the new sleepers are used to place the rails, and finally placing the rails on top of the rubber pads.

[0003] In the existing sleeper replacement operation method, the rubber pad installation process is carried out after the new sleepers are laid out, and this process is completed manually, which makes the sleeper replacement operation less efficient when it is carried out during the window period. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems thereof by adopting a technical solution: a rubber pad pre-installation operation device suitable for new sleepers, comprising: a sleeper changing vehicle, a mounting rod being fixedly connected to the bottom of the sleeper changing vehicle, a traveling mechanism being fixedly connected to the bottom of the mounting rod, and a loading mechanism being fixedly connected to the top of the traveling mechanism;

[0005] The rubber pad pre-installation device for new sleepers also includes:

[0006] A placing mechanism, wherein the top of the placing mechanism is fixedly connected to the bottom of the traveling mechanism;

[0007] The placing mechanism includes a track, the top of which is fixedly connected to the bottom of the travel mechanism, and two tracks are provided. The opposite sides of the track are slidably connected with a bearing assembly, and the inner wall of the bearing assembly is rotatably connected with a cleaning assembly. The inner wall of the track away from the cleaning assembly is fixedly connected with an air collecting assembly, which blows away the dust and debris on the rubber pad where the new sleeper is placed, and then the bearing assembly places the rubber pad on the new sleeper, cleans the contact position between the new sleeper and the rubber pad, so that the rubber pad is in closer contact with the surface of the new sleeper, reducing debris can extend the shock-absorbing effect of the rubber pad, and automatically placing the rubber pad on the new sleeper reduces the work of the staff and improves the work efficiency of the pre-installation work.

[0008] Further, the traveling mechanism includes a mounting seat. The inner wall of the mounting seat is evenly provided with rollers, and the outer wall of the rollers is rotatably connected to the inner wall of the mounting seat. The bottom of the mounting seat is symmetrically provided with rotating frames, and the top of the rotating frames is rotatably connected to the bottom of the mounting seat. The inner wall of the rotating frames is evenly provided with auxiliary wheels, and the outer wall of the auxiliary wheels is rotatably connected to the inner wall of the rotating frames. A straightening component is slidably connected to the inner wall of the mounting seat on the side away from the rotating frames, so that the rubber plate can vertically fall into the loading component, avoiding the rubber cushion plate from shifting during the falling process and getting stuck inside the loading component, which may affect the preloading of the rubber cushion plate.

[0009] Further, the feeding mechanism includes a placing frame. The bottom of the placing frame is fixedly connected to the top of the mounting seat. The inner wall of the placing frame is symmetrically provided with grooves, and a conveyor belt is arranged on the inner wall of the grooves. The top of the placing frame is symmetrically provided with rotating plates, and the outer wall of the rotating plates is rotatably connected to the inner wall of the placing frame. The inner wall of the placing frame at one end away from the conveyor belt is symmetrically provided with rotating rods, and the outer wall of the rotating rods is rotatably connected to the inner wall of the placing frame. A pushing block is rotatably connected to the outer wall of the rotating rods, enabling the rubber plate to be automatically added to the loading component, eliminating the need for workers to bend down each time to place the rubber plate on the new sleeper, avoiding damage to the workers' waists and reducing the burden on the workers.

[0010] Further, the straightening component includes a frame. The top of the frame is fixedly connected with a baffle plate. A square hole is provided on the outer wall of the baffle plate. Springs are symmetrically arranged on the outer wall of the baffle plate away from the square hole. One end of each spring away from the baffle plate is fixedly connected with a pressing plate. Elastic rods are evenly arranged on the outer wall of the pressing plate, and the outer wall of the elastic rods is fixedly connected to the outer wall of the pressing plate. One end of each elastic rod away from the pressing plate is fixedly connected with an elastic plate, and one end of the elastic plate away from the elastic rod is rotatably connected to the outer wall of the baffle plate. While enabling the rubber cushion plate to be automatically fed, the rubber cushion plate is always kept in a vertical state during falling, avoiding excessive tilting of the rubber cushion plate when it is pushed, getting stuck at the falling opening or being unable to enter the loading component, improving the accuracy during automatic feeding and reducing manual work.

[0011] Further, the loading component includes a moving column. The outer wall of the moving column is slidably connected to the inner wall of the track. One end of the moving column away from the track is rotatably connected to a placement seat. Placement grooves are symmetrically provided on the inner wall of the placement seat. Support rods are symmetrically arranged on the outer wall of the placement seat, and the outer wall of the support rods is rotatably connected to the outer wall of the placement seat. A support plate is fixedly connected to one end of the placement seat close to the air collection component. After cleaning the surface of the new sleeper, the support rods rotate to coincide with the placement seat, enabling the rubber cushion plate to fall on the top of the new sleeper. The whole process is automatic feeding and placement, eliminating the need for workers to bend down one by one to place the rubber cushion plates on the new sleepers.

[0012] Furthermore, the cleaning assembly includes a connecting rod, the outer wall of the connecting rod is rotatably connected to the inner wall of the mounting seat, the bottom of the connecting rod is fixedly connected to a counterweight ball, the bottom of the counterweight ball is fixedly connected to a U-shaped rod, the outer wall of the U-shaped rod is fixedly connected to a cleaning roller, the outer wall of the U-shaped rod is fixedly connected to an air outlet pipe, and the outer wall of the counterweight ball is fixedly connected to a connecting pipe, which is convenient for judging the distance between the cleaning roller and the new sleeper, avoiding the situation where the cleaning roller cannot contact the new sleeper when the distance is fixed, affecting the cleaning effect, and blowing away the dust and smaller stones on the surface of the new sleeper, and then the cleaning roller cleans again, keeping the contact position between the new sleeper and the rubber pad free of debris, thereby protecting the service life of the rubber pad.

[0013] Furthermore, the air collecting assembly includes a fixed sleeve, the outer wall of the fixed sleeve is fixedly connected to the inner wall of the track, the inner wall of the fixed sleeve is fixedly connected to an air bag, the outer wall of the air bag is fixedly connected to a movable plate, the outer wall of the movable plate is slidably connected to the inner wall of the fixed sleeve, the top of the fixed sleeve is fixedly connected to an air pipe, and the end of the air pipe away from the fixed sleeve is fixedly connected to a speed change tube.

[0014] A sleeper replacement method suitable for new sleepers, using the rubber pad pre-installation operation device suitable for new sleepers to replace sleepers, comprises the following steps:

[0015] S1: When laying sleepers on a sleeper changing vehicle, the traveling mechanism is first brought into contact with the surface of the rail, and the traveling mechanism is driven by the sleeper changing vehicle to move along the track, and the loading mechanism is filled with rubber pads. The staff can replenish the rubber pads at any time;

[0016] S2: The loading mechanism cooperates with the straightening assembly to drop the rubber pad from the conveyor belt directly toward the load-bearing assembly, so that the rubber pad is placed directly inside the load-bearing assembly;

[0017] S3: When the bearing assembly approaches the gas collecting assembly, the gas collecting assembly is gradually squeezed, so that the gas inside the gas collecting assembly enters the cleaning assembly, and the cleaning assembly blows air to the sleeper to clean the debris and dust on the sleeper;

[0018] S4: After cleaning is completed, the bearing assembly places the rubber pad on the sleeper and then repeats the above steps S1-S3.

[0019] The beneficial effects of the present invention are as follows:

[0020] In the prior art, the pre-installation of rubber pads is usually done manually following the sleeper-changing vehicle, and the rubber pads are placed on the new sleepers while the sleepers are being changed. The present invention arranges a loading mechanism and a traveling mechanism to cooperate with each other, so that the rubber pads can be added to the load-bearing assembly autonomously, avoiding the rubber pads from shifting during the falling process and causing them to get stuck inside the load-bearing assembly. There is no need for manual labor to bend over each time to place the rubber pads on the new sleepers, thus avoiding injuries to the workers' waists and reducing their burden.

[0021] When laying new sleepers, due to the dusty construction environment, dust and pebbles are easily accumulated on the surface of the new sleeper, which can easily damage the surface of the rubber pad, making it unsuitable for long-term use. The present invention provides a placement mechanism to blow away the dust and debris where the new sleeper is placed on the rubber pad, and then the bearing assembly places the rubber pad on the new sleeper, cleans the contact position between the new sleeper and the rubber pad, and makes the rubber pad contact with the surface of the new sleeper closer. Reducing debris can extend the shock-absorbing effect of the rubber pad, and automatically placing the rubber pad on the new sleeper reduces the work of the staff, thereby improving the work efficiency of the pre-installation work.

[0022] When the rubber pad is placed on the new sleeper manually, it is impossible to thoroughly clean the surface of the new sleeper. The present invention provides a cleaning component and an air collecting component. The built-in drive of the placement seat drives the connecting rod to maintain a certain angle with the placement seat, which is convenient for judging the distance between the cleaning roller and the new sleeper, and avoids the situation where the cleaning roller and the new sleeper cannot contact each other when the distance is fixed, affecting the cleaning effect. The airflow generated by the extruded airbag is ejected through the air outlet, so that the dust and smaller stones on the surface of the new sleeper are blown away, and then the cleaning roller cleans again, keeping the contact position between the new sleeper and the rubber pad free of debris, thereby protecting the service life of the rubber pad.

[0023] During automatic loading, due to the large friction between the rubber pad and the conveyor belt, the rubber pad may not be able to quickly separate from the conveyor belt, causing the rubber pad to shift. The present invention provides a straightening component to keep the rubber pad able to load independently while keeping the rubber pad in a vertical state and falling, thereby avoiding the rubber pad from tilting too much when being pushed, getting stuck in the drop port or being unable to enter the load-bearing component, thereby improving the accuracy of automatic loading and reducing manual work.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for specific purposes.

[0037] Example 1, please refer to Figures 1 - 5 , the present invention provides a technical solution: A rubber pad preloading operation device suitable for new sleepers will be described as follows.

[0038] It includes: a sleeper-changing car 5, the bottom of which is fixedly connected to a mounting rod 3, the bottom of which is fixedly connected to a traveling mechanism 1, the top of which is fixedly connected to a feeding mechanism 2, the traveling mechanism 1 wraps around the rails and moves along the rails, the outer wall of the traveling mechanism 1 is symmetrically provided with mounting rods 3, the top of the mounting rods 3 is fixed to the sleeper-changing car 5, so that the traveling mechanism 1 is powered and can travel along the rails, the outer wall of the mounting rods 3 is fixedly connected to the outer wall of the traveling mechanism 1, and the top of the traveling mechanism 1 is fixedly connected to the feeding mechanism 2;

[0039] The rubber pad pre-installation device for new sleepers also includes:

[0040] The placing mechanism 4, the top of the placing mechanism 4 is fixedly connected to the bottom of the traveling mechanism 1;

[0041] When changing sleepers, the sleeper changing vehicle 5 places the new sleepers in sequence at a certain distance under the rails. There is a certain distance between the rails and the new sleepers. At this time, the traveling mechanism 1 moves along the rails, driving the placing mechanism 4 to place rubber pads on the newly laid sleepers. The loading mechanism 2 cooperates with the traveling mechanism 1 to place the rubber pads inside the placing mechanism 4. At the same time, the loading mechanism 2 is manually added with new rubber pads. The placing mechanism 4 cleans the surface of the new sleeper and then places the rubber pads on the new sleeper.

[0042] The travel mechanism 1 includes a mounting seat 101, the inner wall of which is evenly provided with rollers 102, the outer wall of the roller 102 is rotatably connected to the inner wall of the mounting seat 101, a rotating frame 103 is symmetrically provided at the bottom of the mounting seat 101, the top of the rotating frame 103 is rotatably connected to the bottom of the mounting seat 101, the inner wall of the rotating frame 103 is evenly provided with auxiliary wheels 104, the auxiliary wheels 104 and the rollers 102 are both made of rubber, the outer wall of the auxiliary wheels 104 is rotatably connected to the inner wall of the rotating frame 103, and the inner wall of the mounting seat 101 away from the rotating frame 103 is slidably connected to a straightening component 105.

[0043] During installation, the bottom of the mounting seat 101 is brought close to the rail, and then the mounting seat 101 drives the rotating frame 103 to rotate, so that the auxiliary wheel 104 is stuck in the depression of the rail, and the roller 102 contacts the top of the rail, so that the mounting seat 101 is stuck on the rail and can move along the rail under the drive of the sleeper changing car 5. The straightening component 105 cooperates with the feeding mechanism 2 to keep the rubber plate falling vertically into the inside of the bearing component 402, avoiding the rubber pad from deviating during the falling process, causing it to be stuck in the inside of the bearing component 402, affecting the pre-installation of the rubber pad.

[0044] The feeding mechanism 2 includes a placing frame 201. A falling opening is formed on the bottom of the placing frame 201 and the surface of the mounting base 101. The bottom of the placing frame 201 is fixedly connected to the top of the mounting base 101. Grooves 202 are symmetrically formed on the inner wall of the placing frame 201. A conveyor belt 206 is arranged on the inner wall of the groove 202. Rotating plates 203 are symmetrically arranged on the top of the placing frame 201. The outer wall of the rotating plate 203 is rotatably connected to the inner wall of the placing frame 201. Rotating rods 204 are symmetrically arranged on the inner wall of the placing frame 201 at one end away from the conveyor belt 206. The outer wall of the rotating rod 204 is rotatably connected to the inner wall of the placing frame 201. A pushing block 205 is rotatably connected to the outer wall of the rotating rod 204. When the rubber cushion plate on one side is taken away from the conveyor belt 206 by the straightening component 105, the rotating rod 204 on the other side rotates to make the pushing block 205 pass through the straightening component 105 and push the rubber cushion plate down, so that the rubber cushion plate drops.

[0045] Before starting work, the rubber cushion plates are vertically placed on the conveyor belt 206 in the same direction. When the loading component 402 places the rubber cushion plates, the contact surface between the rubber cushion plates and the new sleeper is kept facing down. When starting to lay the new sleeper, as the traveling mechanism 1 advances, the conveyor belt 206 conveys the rubber cushion plates to the falling opening of the placing frame 201. The conveyor belt 206 works intermittently. Then, the rotating plate 203 pushes the rubber cushion plates onto the straightening component 105. The rotating plate 203 works alternately left and right. Workers need to fill the empty positions on the conveyor belt 206 with rubber cushion plates and place them on the conveyor belt 206 in the same direction, so that the rubber plates are automatically added to the loading component 402, without the need for workers to bend down each time to place the rubber plates on the new sleeper, avoiding damage to the workers' waists and reducing the burden on the workers.

[0046] The placing mechanism 4 includes tracks 401. The top of the tracks 401 is fixedly connected to the bottom of the traveling mechanism 1. There are two tracks 401. A loading component 402 is slidably connected to the opposite sides of the tracks 401. A cleaning component 403 is rotatably connected to the inner wall of the loading component 402. An air collecting component 404 is fixedly connected to the inner wall of the tracks 401 on the side away from the cleaning component 403.

[0047] After placing the rubber cushion plate inside the bearing assembly 402, the bearing assembly 402 drives the rubber cushion plate to move along the track 401. During the movement, the bearing assembly 402 rotates to the horizontal position. At this time, the rubber cushion plate is parallel to the new sleeper, and the surface of the rubber cushion plate in contact with the sleeper faces downward. During the process of the bearing assembly 402 approaching the air collecting assembly 404, the air collecting assembly 404 pushes the gas into the cleaning assembly 403. After the bearing assembly 402 rotates to the horizontal position, the cleaning assembly 403 rotates out of the bearing assembly 402 and contacts the surface of the new sleeper, and squeezes and blows the gas inside the air collecting assembly 404 onto the surface of the new sleeper, blowing away the dust and debris at the place where the new sleeper places the rubber cushion plate. Subsequently, the bearing assembly 402 places the rubber cushion plate on the new sleeper, cleans the position where the new sleeper contacts the rubber cushion plate, makes the surface contact between the rubber cushion plate and the new sleeper closer, and reducing debris can extend the shock absorption effect of the rubber cushion plate. Automatically placing the rubber cushion plate on the new sleeper reduces the work of the staff and improves the work efficiency of the preloading work.

[0048] Embodiment 2, please refer to Figures 1 - 11 , the present invention provides a technical solution: on the basis of Embodiment 1, the alignment component 105 includes a frame 1052. The outer wall of the frame 1052 is slidably connected to the inner wall of the mounting seat 101. The inner wall of the frame 1052 is an inclined surface to make the rubber cushion plate fall quickly. There is a small platform near the frame 1052 close to the baffle 1051, so that the rubber plate can first contact the platform. The top of the frame 1052 is fixedly connected with a baffle 1051. A square hole 1053 is opened on the outer wall of the baffle 1051. The square hole 1053 can accommodate the pushing block 205 to pass through and push out the rubber cushion plate. Springs 1055 are symmetrically arranged on the outer wall of the baffle 1051 away from the square hole 1053. One end of the spring 1055 away from the baffle 1051 is fixedly connected with a pressing plate 1057. Elastic rods 1056 are uniformly arranged on the outer wall of the pressing plate 1057. The outer wall of the elastic rod 1056 is fixedly connected with the outer wall of the pressing plate 1057. One end of the elastic rod 1056 away from the pressing plate 1057 is fixedly connected with an elastic plate 1054. One end of the elastic plate 1054 away from the elastic rod 1056 is rotatably connected to the outer wall of the baffle 1051.

[0049] When the rotating plate 203 on the left pushes the rubber cushion plate off the conveyor belt 206, the baffle 1051 is close to the left side at this time. One corner of the rubber cushion plate first falls on the platform of the frame 1052. During the process of the rotating plate 203 pushing the rubber cushion plate, the right side of the rubber cushion plate contacts the pressing plate 1057 and squeezes the pressing plate 1057, causing the pressing plate 1057 to pull the elastic rod 1056, so that the elastic rod 1056 drags the elastic plates 1054 to approach each other, making the elastic plates 1054 clamp the rubber cushion plate. Then the rotating plate 203 continues to rotate to push the rubber cushion plate off the conveyor belt 206. At the same time, the frame 1052 moves to the right side. At this time, the rotating rod 204 on the right drives the pushing block 205 to rotate a certain angle, so that the pushing block 205 just passes through the square hole 1053, contacts the rubber cushion plate, and when the frame 1052 continues to move to the right, pushes the rubber cushion plate from the small platform to the gap of the frame 1052, making the rubber cushion plate vertically fall onto the bearing assembly 402. When the rotating plate 203 pushes the rubber cushion plate on the right side, the operation is the same as above, but in the opposite direction.

[0050] While ensuring that the rubber cushion plate can be automatically loaded, the rubber cushion plate is always kept in a vertical state when it falls, avoiding excessive tilting of the rubber cushion plate when it is pushed, getting stuck at the falling opening or unable to enter the bearing assembly 402, improving the accuracy during automatic loading and reducing manual work.

[0051] The bearing assembly 402 includes a moving column 4021. The outer wall of the moving column 4021 is slidably connected to the inner wall of the track 401. One end of the moving column 4021 away from the track 401 is rotatably connected to a placement seat 4022. The inner wall of the placement seat 4022 is symmetrically provided with placement grooves 4023. The outer wall of the placement seat 4022 is symmetrically provided with support rods 4024. The outer wall of the support rods 4024 is rotatably connected to the outer wall of the placement seat 4022. One end of the placement seat 4022 close to the air collection assembly 404 is fixedly connected to a support plate 4025. The material of the support plate 4025 is a magnet.

[0052] The air collection assembly 404 includes a fixed sleeve 4041. The fixed sleeve 4041 is made of metal. The outer wall of the fixed sleeve 4041 is fixedly connected to the inner wall of the track 401. The inner wall of the fixed sleeve 4041 is fixedly connected to an airbag 4042. The outer wall of the airbag 4042 is fixedly connected to a moving plate 4043. The moving plate 4043 is an iron plate. The outer wall of the moving plate 4043 is slidably connected to the inner wall of the fixed sleeve 4041. The top of the fixed sleeve 4041 is fixedly connected to an air pipe 4044. One end of the air pipe 4044 away from the fixed sleeve 4041 is fixedly connected to a variable-speed pipe 4045. The diameters of both ends of the variable-speed pipe 4045 are different, which can increase the gas flow rate.

[0053] When the rubber cushion drops vertically, the moving column 4021 drives the placement seat 4022 to be placed vertically, so that the rubber cushion just falls into the placement seat 4022. At this time, the support rod 4024 is in an inclined state to prevent the rubber cushion from falling off. Then, the moving column 4021 drives the placement seat 4022 to move along the track 401, and during the movement, the placement seat 4022 gradually rotates to the horizontal, making the bottom of the rubber cushion parallel to the new sleeper. During the movement of the placement seat 4022, the support plate 4025 contacts and sucks the moving plate 4043, and then during the continued movement, the moving plate 4043 squeezes the airbag 4042, so that the gas in the airbag 4042 enters the cleaning assembly 403 along the air pipe 4044. Since during this process, the traveling mechanism 1 has been moving forward slowly, and the gas collecting assembly 404 is arranged on the track 401 facing the moving direction. After cleaning the surface of the new sleeper, the support rod 4024 rotates to coincide with the placement seat 4022, so that the rubber cushion falls on the top of the new sleeper. The whole process is automatic feeding and placement, without the need for manual bending to place the rubber cushions on the new sleepers one by one. After the pre-installation is completed, the placement seat 4022 returns to the initial position, the support plate 4025 drives the moving plate 4043 to move back to its original position, and re-fills the airbag 4042 with air. Then the support plate 4025 separates from the moving plate 4043 to continue the pre-installation of the next rubber cushion.

[0054] The cleaning assembly 403 includes a connecting rod 4031. The outer wall of the connecting rod 4031 is rotatably connected to the inner wall of the placement seat 4022. A counterweight ball 4032 is fixedly connected to the bottom of the connecting rod 4031. A U-shaped rod 4034 is fixedly connected to the bottom of the counterweight ball 4032. A cleaning roller 4035 is fixedly connected to the outer wall of the U-shaped rod 4034. The cleaning roller 4035 is a brush roller. An air outlet pipe 4036 is fixedly connected to the outer wall of the U-shaped rod 4034. A filter screen is arranged at the air outlet of the air outlet pipe 4036. A connecting pipe 4033 is fixedly connected to the outer wall of the counterweight ball 4032. The connecting pipe 4033 and the air pipe 4044 are connected by a hose. The gas in the air pipe 4044 enters the U-shaped rod 4034 through the ventilation hole in the middle of the counterweight ball 4032, and then sprays out through the air outlet pipe 4036.

[0055] When the placement seat 4022 moves to the horizontal position, the counterweight ball 4032 drives the connecting rod 4031 to rotate under the action of gravity, so that the cleaning roller 4035 is placed on the new sleeper. The built-in drive of the placement seat 4022 drives the connecting rod 4031 to maintain a certain angle with the placement seat 4022, which is convenient for judging the distance between the cleaning roller 4035 and the new sleeper, and avoids the situation where the cleaning roller 4035 and the new sleeper cannot contact each other when the distance is fixed, affecting the cleaning effect. At this time, the air outlet position of the air outlet pipe 4036 is flush with the surface of the new sleeper, and the air flow generated by the squeezing airbag 4042 is ejected through the air outlet, so that the dust and smaller stones on the surface of the new sleeper are blown away, and then the cleaning roller 4035 cleans again, keeping the contact position between the new sleeper and the rubber pad free of debris, thereby protecting the service life of the rubber pad.

[0056] A sleeper replacement method suitable for new sleepers, using the rubber pad pre-installation operation device suitable for new sleepers to replace sleepers, comprises the following steps:

[0057] S1: When the sleeper changing vehicle 5 is laying the sleepers, the traveling mechanism 1 is first brought into contact with the surface of the track 401, and the traveling mechanism 1 is moved along the track 401 by the sleeper changing vehicle 5, and the feeding mechanism 2 is filled with rubber pads. The staff can replenish the rubber pads at any time;

[0058] S2: The loading mechanism 2 cooperates with the straightening assembly 105 to drop the rubber pad from the conveyor belt 206 directly toward the carrier assembly 402 so that the rubber pad is placed directly inside the carrier assembly 402;

[0059] S3: As the carrying assembly 402 approaches the gas collecting assembly 404, the gas collecting assembly 404 is gradually squeezed, so that the gas inside the gas collecting assembly 404 enters the cleaning assembly 403, and the cleaning assembly 403 blows air to the sleeper to clean away debris and dust on the sleeper;

[0060] S4: After cleaning is completed, the bearing assembly 402 places the rubber pad on the sleeper, and then repeats the above steps S1-S3.

[0061] The specific workflow is as follows:

[0062] During installation, the bottom of the mounting seat 101 is brought close to the rail, and then the mounting seat 101 drives the rotating frame 103 to rotate, so that the auxiliary wheel 104 is stuck in the depression of the rail, and the roller 102 contacts the top of the rail, so that the mounting seat 101 is stuck on the rail and can move along the rail under the drive of the sleeper changing car 5. The straightening component 105 cooperates with the feeding mechanism 2 to keep the rubber plate falling vertically into the inside of the bearing component 402, avoiding the rubber pad from deviating during the falling process, causing it to be stuck in the inside of the bearing component 402, affecting the pre-installation of the rubber pad.

[0063] Before starting work, place the rubber pads vertically on the conveyor belt 206 in a consistent direction. When cooperating with the loading component 402 to place the rubber pads, ensure that the contact surface of the rubber pads with the new sleeper faces downward. When starting to lay the new sleeper, as the traveling mechanism 1 advances, the conveyor belt 206 conveys the rubber pads to the dropping opening of the placement frame 201. The conveyor belt 206 works intermittently, and then the rotating plate 203 pushes the rubber pads onto the straightening component 105. The rotating plate 203 works alternately left and right. Workers need to replenish the rubber pads at the positions vacated on the conveyor belt 206 and place them on the conveyor belt 206 in the same direction, so that the rubber pads are automatically added to the loading component 402.

[0064] After placing the rubber pads inside the loading component 402, the loading component 402 drives the rubber pads to move along the track 401. During the movement, the loading component 402 rotates to the horizontal position. At this time, the rubber pads are parallel to the new sleeper, and the surface of the rubber pads in contact with the sleeper faces downward. As the loading component 402 approaches the air collecting component 404, the air collecting component 404 pushes the gas into the cleaning component 403. After the loading component 402 rotates to the horizontal position, the cleaning component 403 rotates out of the loading component 402 and contacts the surface of the new sleeper, and squeezes and blows the gas inside the air collecting component 404 onto the surface of the new sleeper to blow away the dust and debris at the place where the rubber pads are placed on the new sleeper. Subsequently, the loading component 402 places the rubber pads on the new sleeper and cleans the position where the new sleeper contacts the rubber pads to make the contact between the rubber pads and the surface of the new sleeper closer.
