[0014] A sleeper replacement method suitable for new sleepers comprises the following steps:

[0015] S1: When the sleeper changing vehicle is laying the sleepers, 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 401, and the feeding mechanism is filled with rubber pads, and the staff can replenish the rubber pads at any time;

[0016] S2: The feeding 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 blows air to the sleeper to clean up the debris and dust on the sleeper;

[0018] S4: After cleaning, the load-bearing assembly places the rubber pad on the sleeper and then repeats the above operation.

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

[0020] 1. 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 feeding mechanism and a traveling mechanism to cooperate with each other, so that the rubber pads can be added to the load-bearing assembly autonomously, thereby preventing the rubber pads from shifting during the falling process and getting stuck inside the load-bearing assembly. There is no need for manual bending over to place the rubber pads on the new sleepers each time, thus avoiding injuries to the workers' waists and reducing the burden on the workers.

[0021] 2. When laying new sleepers, due to the dusty construction environment, dust and pebbles are easily accumulated on the surface of the new sleepers, which can easily damage the surface of the rubber pads and is not conducive to long-term use. The present invention provides a placement mechanism to blow away the dust and debris where the new sleepers are placed on the rubber pads, and then the bearing assembly places the rubber pads on the new sleepers, and cleans the contact position between the new sleepers and the rubber pads to make the rubber pads more closely contact with the surfaces of the new sleepers. Reducing debris can extend the shock absorbing effect of the rubber pads, and automatically placing the rubber pads on the new sleepers reduces the work of the staff, thereby improving the work efficiency of the pre-installation work.

[0022] 3. 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, which affects the cleaning effect. The airflow generated by the extruded airbag is ejected through the air outlet to blow away the dust and smaller stones on the surface of the new sleeper, and then the cleaning roller cleans again to keep the contact position between the new sleeper and the rubber pad free of debris, thereby protecting the service life of the rubber pad.

[0023] 4. 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 detach from the conveyor belt, causing the rubber pad to shift. The present invention provides a straightening assembly to keep the rubber pad able to load independently while keeping the rubber pad in a vertical state and not falling, thereby preventing the rubber pad from tilting too much when being pushed, getting stuck in the drop port or being unable to enter the load-bearing assembly, thereby improving the accuracy of automatic loading and reducing manual work.

The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0037] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a rubber pad pre-installation device suitable for new sleepers is described as follows.

[0038] It comprises: a sleeper-changing vehicle 5, a mounting rod 3 is fixedly connected to the bottom of the sleeper-changing vehicle 5, a traveling mechanism 1 is fixedly connected to the bottom of the mounting rod 3, a feeding mechanism 2 is fixedly connected to the top of the traveling mechanism 1, the traveling mechanism 1 wraps 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 vehicle 5, so that the traveling mechanism 1 is powered and can travel along the rails, the outer wall of the mounting rod 3 is fixedly connected to the outer wall of the traveling mechanism 1, and the feeding mechanism 2 is fixedly connected to the top of the traveling mechanism 1;

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

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

[0041] When replacing 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 feeding mechanism 2 cooperates with the traveling mechanism 1 to place the rubber pads inside the placing mechanism 4. At the same time, new rubber pads are manually added to the feeding mechanism 2. The placing mechanism 4 cleans the surface of the new sleepers and then places the rubber pads on the new sleepers.

[0042] The traveling mechanism 1 includes a mounting seat 101, the inner wall of which is evenly provided with rollers 102, the outer wall of the rollers 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 a straightening component 105 is slidably connected to the inner wall of the mounting seat 101 away from the rotating frame 103.

[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 vehicle 5. The straightening component 105 cooperates with the feeding mechanism 2 to keep the rubber plate falling vertically into the bearing component 402, so as to avoid the rubber pad from shifting during the falling process, causing it to be stuck in the bearing component 402, affecting the pre-installation of the rubber pad.

[0044] The loading mechanism 2 includes a placement frame 201, a drop opening is provided at the bottom of the placement frame 201 and the surface of the mounting seat 101, the bottom of the placement frame 201 is fixedly connected to the top of the mounting seat 101, a groove 202 is symmetrically provided on the inner wall of the placement frame 201, a conveyor belt 206 is provided on the inner wall of the groove 202, a rotating plate 203 is symmetrically provided on the top of the placement frame 201, the outer wall of the rotating plate 203 is rotatably connected to the inner wall of the placement frame 201, a rotating rod 204 is symmetrically provided on the inner wall of the placement frame 201 away from the conveyor belt 206, the outer wall of the rotating rod 204 is rotatably connected to the inner wall of the placement frame 201, and the outer wall of the rotating rod 204 is rotatably connected to the pushing block 205, when the straightening component 105 takes the rubber pad on one side away from the conveyor belt 206, the rotating rod 204 on the other side rotates to pass the pushing block 205 through the straightening component 105, pushes the rubber pad down, and makes the rubber pad fall.

[0045] Before starting work, place the rubber pad vertically on the conveyor belt 206 in a consistent direction, and when placing the rubber pad on the bearing assembly 402, keep the contact surface of the rubber pad and the new sleeper facing downward. When starting to lay the new sleeper, as the traveling mechanism 1 moves forward, the conveyor belt 206 conveys the rubber pad to the drop port of the placement frame 201, and the conveyor belt 206 works intermittently. Then the turn plate 203 pushes the rubber pad onto the straightening assembly 105, and the turn plate 203 works alternately left and right. The worker needs to fill the empty position on the conveyor belt 206 with the rubber pad and place it on the conveyor belt 206 in the same direction, so that the rubber plate can be automatically added to the bearing assembly 402, and there is no need to manually bend down each time to place the rubber plate on the new sleeper, thereby avoiding damage to the worker's waist and reducing the burden on the worker.

[0046] The placement mechanism 4 includes a track 401, the top of which is fixedly connected to the bottom of the travel mechanism 1, and two tracks 401 are provided. A bearing assembly 402 is slidably connected to the opposite side of the track 401, a cleaning assembly 403 is rotatably connected to the inner wall of the bearing assembly 402, and a gas collecting assembly 404 is fixedly connected to the inner wall of the track 401 away from the cleaning assembly 403.

[0047] After the rubber pad is placed inside the bearing component 402, the bearing component 402 drives the rubber pad to move along the track 401. During the movement, the bearing component 402 rotates to a horizontal position, at which time the rubber pad is parallel to the new sleeper, so that the surface of the rubber pad in contact with the sleeper faces downward. In the process of the bearing component 402 approaching the gas collecting component 404, the gas collecting component 404 pushes the gas into the cleaning component 403. After the bearing component 402 rotates to a horizontal position, the cleaning component 403 rotates out of the bearing component 402, contacts the surface of the new sleeper, and squeezes and blows the gas inside the gas collecting component 404 to the surface of the new sleeper, blowing away the dust and debris where the new sleeper is placed on the rubber pad. Then the bearing component 402 places the rubber pad on the new sleeper, cleans the contact position between the new sleeper and the rubber pad, makes the contact between the rubber pad and the surface of the new sleeper closer, reduces debris, and prolongs the shock absorbing effect of the rubber pad. 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.

[0048] Example 2, please refer to Figure 1-Figure 11 The present invention provides a technical solution: on the basis of the first embodiment, the straightening assembly 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, so that the rubber pad can fall quickly, the frame 1052 has a small platform near the baffle 1051, so that the rubber plate can contact the platform first, the top of the frame 1052 is fixedly connected to the baffle 1051, and the outer wall of the baffle 1051 is provided with a square hole 1053, and the square hole 1053 can accommodate the push block 205 passing through , push out the rubber pad, and a spring 1055 is symmetrically arranged on the outer wall of the baffle 1051 away from the square hole 1053, and one end of the spring 1055 away from the baffle 1051 is fixedly connected to a pressing plate 1057, and an outer wall of the pressing plate 1057 is evenly arranged with elastic rods 1056, and the outer wall of the elastic rod 1056 is fixedly connected to the outer wall of the pressing plate 1057, and one end of the elastic rod 1056 away from the pressing plate 1057 is fixedly connected to an elastic plate 1054, and 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 pad off the conveyor belt 206, the baffle 1051 is close to the left, and a corner of the rubber pad first falls on the platform on the frame 1052. In the process of the rotating plate 203 pushing the rubber pad, the right side of the rubber pad contacts the pressing plate 1057 and squeezes the pressing plate 1057, so that the pressing plate 1057 pulls the elastic rod 1056, so that the elastic rod 1056 pulls the elastic plates 1054 closer to each other, so that the elastic plates 1054 clamp the rubber pad, and then the rotating plate 203 continues to rotate to push the rubber pad off the conveyor belt 206, and at the same time the frame 1052 moves to the right. 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 and contacts the rubber pad. When the frame 1052 continues to move to the right, the rubber pad is pushed from the small platform to the gap in the frame 1052, so that the rubber pad falls vertically onto the bearing assembly 402. When the rotating plate 203 pushes the rubber pad on the right, the operation is the same as above, but in the opposite direction.

[0050] While keeping the rubber pad capable of autonomous loading, the rubber pad is always kept in a vertical state when falling, to avoid the rubber pad being tilted too much when being pushed, getting stuck in the drop opening or being unable to enter the bearing assembly 402, thereby improving the accuracy of automatic loading and reducing manual work.

[0051] The supporting component 402 includes a movable column 4021, the outer wall of the movable column 4021 is slidably connected to the inner wall of the track 401, the end of the movable 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, and the end of the placement seat 4022 close to the gas collecting component 404 is fixedly connected to a support plate 4025, and the material of the support plate 4025 is a magnet.

[0052] The gas collecting component 404 includes a fixed sleeve 4041, which 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 air bag 4042. The outer wall of the air bag 4042 is fixedly connected to a movable plate 4043. The movable plate 4043 is an iron plate. The outer wall of the movable 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. The end of the air pipe 4044 away from the fixed sleeve 4041 is fixedly connected to a speed change tube 4045. The diameters of the two ends of the speed change tube 4045 are different, which can increase the gas flow rate.

[0053] When the rubber pad falls vertically, the moving column 4021 drives the placement seat 4022 to be placed vertically, so that the rubber pad falls exactly in the placement seat 4022. At this time, the support rod 4024 is in an inclined state to prevent the rubber pad from falling off. Then the moving column 4021 drives the placement seat 4022 to move along the track 401, and the placement seat 4022 gradually rotates to a horizontal position during the movement, so that the bottom of the rubber pad is parallel to the new rail sleeper. During the movement of the placement seat 4022, the support plate 4025 contacts and absorbs the moving plate 4043. Then, during the continued movement, the moving plate 4043 squeezes the airbag 4042, so that the gas in the airbag 4042 moves along the air pipe 4044. Enter the cleaning component 403. Since the traveling mechanism 1 has been moving forward slowly during this process, the air collecting component 404 is set on the track 401 facing the moving direction. After cleaning the surface of the new sleeper, the support rod 4024 is rotated to overlap with the placement seat 4022, so that the rubber pad falls on the top of the new sleeper. The whole process of loading and placing is automatic, and there is no need to manually bend down to place the rubber pads on the new sleeper one by one. After the pre-installation is completed, the placement seat 4022 returns to the initial position, and the support plate 4025 drives the movable plate 4043 to move and reset, and re-fill the airbag 4042, and then the support plate 4025 is separated from the movable plate 4043, and the pre-installation of the next rubber pad is continued.

[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 mounting seat 4022, the bottom of the connecting rod 4031 is fixedly connected to a counterweight ball 4032, the bottom of the counterweight ball 4032 is fixedly connected to a U-shaped rod 4034, the outer wall of the U-shaped rod 4034 is fixedly connected to a cleaning roller 4035, the cleaning roller 4035 is a roller brush, the outer wall of the U-shaped rod 4034 is fixedly connected to an air outlet pipe 4036, a filter is provided at the air outlet of the air outlet pipe 4036, the outer wall of the counterweight ball 4032 is fixedly connected to a connecting pipe 4033, 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 air vent in the middle of the counterweight ball 4032, and then enters the air outlet pipe 4036 for ejection.

[0055] When the placement seat 4022 moves to a 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, thereby 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 airflow 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 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, so that the traveling mechanism 1 moves along the track 401 under the drive of the sleeper changing vehicle 5, and the feeding mechanism 2 is filled with rubber pads, and the staff can replenish the rubber pads at any time;

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

[0059] S3: When the bearing 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 blows air to the sleeper to clean up the debris and dust on the sleeper;

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

[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 vehicle 5. The straightening component 105 cooperates with the feeding mechanism 2 to keep the rubber plate falling vertically into the bearing component 402, so as to avoid the rubber pad from shifting during the falling process, causing it to be stuck in 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, and when placing the rubber pads on the load-bearing component 402, keep the contact surface of the rubber pads and the new sleepers facing downward. When starting to lay new sleepers, as the traveling mechanism 1 moves forward, the conveyor belt 206 conveys the rubber pads to the drop port of the placement frame 201, and the conveyor belt 206 works intermittently. The rubber pads are then pushed onto the straightening component 105 by the turntable 203, and the turntable 203 works alternately left and right. Workers need to fill the empty positions on the conveyor belt 206 with rubber pads and place them on the conveyor belt 206 in the same direction, so that the rubber plates can be added to the load-bearing component 402 autonomously.

[0064] After the rubber pad is placed inside the bearing assembly 402, the bearing assembly 402 drives the rubber pad to move along the track 401. During the movement, the bearing assembly 402 rotates to a horizontal position. At this time, the rubber pad is parallel to the new sleeper, so that the surface of the rubber pad in contact with the sleeper faces downward. In the process of the bearing assembly 402 approaching the gas collecting assembly 404, the gas collecting assembly 404 pushes the gas into the cleaning assembly 403. After the bearing assembly 402 rotates to a horizontal position, the cleaning assembly 403 rotates out of the bearing assembly 402, contacts the surface of the new sleeper, and squeezes and blows the gas inside the gas collecting assembly 404 to the surface of the new sleeper, blowing away the dust and debris where the rubber pad is placed on the new sleeper. Then the bearing assembly 402 places the rubber pad on the new sleeper, cleans the contact position between the new sleeper and the rubber pad, and makes the contact between the rubber pad and the surface of the new sleeper closer.
