Description

Technical Field

[0001] This invention relates to the field of motor technology, specifically to a motor for a railway switch machine and its usage method. Background Technology

[0002] A switch is a turnout switching device that guides locomotives and rolling stock to travel along the main line or siding. It is used to switch and lock turnouts and to indicate the position of the turnout switch rails. When a train switches from one track to another, the switch guides the wheel flanges to smoothly enter the designated track. It is generally composed of a motor, reducer, friction connector, automatic opening and closing device, main shaft, operating rod, indicator rod, shift contactor, base and cover.

[0003] After the electric motor drives the turnout to rotate and adjust, the output shaft of the motor is still connected to the turnout. However, when the train passes over the track, it will bring a large vibration force to the track. When the motor is fixed to the ground, the large vibration force can easily cause the output shaft of the motor to deform or the connection of the motor to loosen. The deformation of the output shaft will affect the amount of movement when it drives the track to move. The loose connection will easily affect the subsequent operation of the motor or the displacement affected by the vibration force when the train passes. The existing motors used in railway switch machines do not have the ability to resist the vibration force generated by the train. Summary of the Invention

[0004] To address the problems of loosening of the fixed mechanism or deformation of the output rod of existing railway switch machine motors due to vibration from train operation, this invention provides a railway switch machine motor and its usage method to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A motor for a railway switch machine includes a motor body for the railway switch machine, a fixed box plate is provided on the side of the motor body, a fixed plate is fixedly fixed to the output end of the motor body through the fixed box plate, and a fixed sleeve plate is fixed to the outer surface of the fixed plate. A shock-absorbing rubber sleeve is fixedly fitted inside the fixing box plate on the side of the fixing plate, and the shock-absorbing rubber sleeve is fitted on the outer surface of the fixing plate. A fixing plate is fixed on the motor body outside the output end of the motor body. A connecting base plate is fixed to the bottom of the motor body by bolts. A shock-absorbing rubber block is glued to the bottom surface of the connecting base plate. A fixing bracket is fixed to the bottom surface of the shock-absorbing rubber block. The bottom surface of the fixing bracket is fixed to the top surface of the fixing base plate.

[0006] Furthermore, the fixed plate is configured as a horizontally placed T-shape, the shock-absorbing rubber sleeve is configured as a hollow I-shape, the inside of the shock-absorbing rubber sleeve is rotatably fitted on the outside of the fixed plate, the inner diameter of the shock-absorbing rubber sleeve is larger than the outer diameter of the fixed plate inside it, and the outer diameter of the shock-absorbing rubber sleeve is equal to the outer diameter of the fixed plate.

[0007] Furthermore, a shock-absorbing ring is fixed to the side of the fixed connecting plate near the fixed box plate. Several support plates are equidistantly arranged on the outer surface of the shock-absorbing ring. A fixed plate is fixed to the fixed box plate on the outer side of each support plate. Several first sliding rods are slidably sleeved on each fixed plate. One end of each first sliding rod that extends to the inner side of the fixed plate is fixed to the outer side of the support plate. A second spring is sleeved on each first sliding rod between the support plate and the fixed plate. Both ends of each second spring abut against the support plate and the fixed plate, respectively.

[0008] Furthermore, the inner diameter of the shock-absorbing ring is larger than the outer diameter of the shock-absorbing rubber sleeve, the thickness of the shock-absorbing rubber sleeve extending to one end inside the shock-absorbing ring is equal to the thickness of the shock-absorbing ring, each of the support plates is configured as a fan shape that cooperates with the shock-absorbing ring, the arc length of each support plate is less than one-quarter of the arc length of the shock-absorbing ring, and the thickness of each support plate is equal to the thickness of the shock-absorbing ring.

[0009] Furthermore, the fixed plate has several sliding holes equidistantly arranged inside to cooperate with the first sliding rod, and each end of the first sliding rod extending to the outside of the fixed plate is threaded with a limiting cap with a diameter larger than the sliding hole.

[0010] Furthermore, servo cylinders are installed on the top surfaces of the fixed base plates on both sides of the fixed bracket, and fixed rods are fixed to the output ends of the two servo cylinders. The top edge of the fixed rod is set to be arc-shaped. Positioning sleeves are fixed on both sides of the motor body above the two fixed rods, and positioning holes that cooperate with the fixed rods are opened inside the two positioning sleeves.

[0011] Furthermore, the width of the shock-absorbing rubber block is smaller than the width of the bottom surface of the connecting base plate and the top surface of the fixed bracket. The bottom surface of the fixed base plate is flush with the bottom surface of the fixed box plate. Several fixing holes are equally spaced on both sides of the fixed base plate.

[0012] Furthermore, a connecting plate is fixed on the side wall of the connecting base plate on the side of each servo cylinder, and a spacer plate is fixed on the bottom surface of the connecting plate. Movable push plates are attached to both sides of the spacer plate. Second slide rods are symmetrically fixed on the outer side of each movable push plate. The second slide rods are slidably sleeved inside the support base plate. A first spring is sleeved on the second slide rod between the outer side of each movable push plate and the inner wall of the support base plate. The two ends of each first spring abut against the movable push plate and the support base plate, respectively.

[0013] Furthermore, each of the supporting base plates is U-shaped, and the bottom of the supporting base plate is fixed to the top surface of the fixed base plate by bolts. The top surface of the supporting base plate is located below the bottom surface of the connecting plate. Sliding holes that cooperate with the second sliding rod are opened on both sides of the supporting base plate. A limiting cap is threaded on one end of each second sliding rod extending to the outside of the supporting base plate. The diameter of the limiting cap is larger than the diameter of the sliding hole. The height of each movable push plate is smaller than the height of the partition plate.

[0014] Furthermore, a method for using a motor for a railway switch machine includes the following steps: Step A: Fix the motor body while it is running; Step A1: When the motor body drives the switch machine, the servo cylinder operates, driving the fixed rod to move upward and insert into the positioning hole of the positioning sleeve plate, thereby positioning the motor body. Step A2: After the switch machine finishes running, the servo cylinder moves the fixed rod out of the positioning hole, and at this time the fixed rod releases its limit on the motor body. Step B: Provide shock absorption protection for the motor body when the train passes; Step B1: When the train passes the motor body, the vibration generated by the train's movement acts on the fixed box plate and the fixed base plate. When the fixed box plate receives the vibration force and shakes, it pulls the shock-absorbing rubber sleeve, and absorbs part of the vibration force through the deformation of the shock-absorbing rubber sleeve. Step B2: At the same time, the fixed box plate moves the fixed plate on the first slide rod. While sliding, the second spring is compressed. The restoring force of the second spring offsets part of the compressive force and further offsets part of the vibration force brought by the fixed box plate, thereby providing shock absorption protection for the fixed plate. Step B3: When the fixed base plate receives vibration, it causes the fixed bracket to shake. When the fixed bracket shakes, it pulls on the shock-absorbing rubber block, causing the shock-absorbing rubber block to deform. The deformation of the shock-absorbing rubber block absorbs part of the vibration force. Step B4: When the fixed base plate shakes, it also causes the supporting base plate to shake on the partition plate and compresses the first spring. The restoring force of the second spring offsets part of the vibration force, thereby providing shock absorption protection for the motor body. Step C: After the train passes, the motor body returns to its initial position under the push of the first and second springs, thereby aligning the positioning hole inside the positioning sleeve with the fixing rod, so that the fixing rod can be inserted into the positioning sleeve when the motor body runs again.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by releasing the limiting fixation of the motor after the turnout is rotated and adjusted, the motor can be protected by the shock absorption mechanism, thereby reducing the vibration impact on the motor when the train passes. This solves the problem of loose fixing or output rod deformation of the existing railway switch machine motor under the influence of train vibration during use, and improves the service life and stability of the motor during use.

[0016] 2. In this invention, the multi-angle buffer structure on the outside of the fixed ring can provide multi-angle shock absorption protection for the motor when it is subjected to vibrations transmitted from the train. At the same time, the shock-absorbing rubber sleeve bonded inside the fixed box plate can reduce the transmission of vibration force from the fixed box plate to the motor, thereby ensuring the firmness and stability of the connection between the fixed plate and the turnout joint, and thus further protecting the motor.

[0017] 3. In this invention, the shock-absorbing rubber block at the bottom of the motor can reduce the transmission of vibration to the motor when the motor is subjected to vibration caused by the bottom surface vibration during train operation. Furthermore, the detachable design of the motor and the connecting base plate makes it convenient to separate the motor for maintenance and repair, thus improving the convenience of maintenance during motor use.

[0021] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 and Figure 4 A motor for a railway switch machine includes a motor body 1 for the railway switch machine. A fixed box plate 2 is provided on the side of the motor body 1. A fixed plate 3 is fixed to the output end of the motor body 1 through the fixed box plate 2. The fixed plate 3 is configured as a horizontally placed T-shape. A fixed sleeve plate 4 is fixed to the outer surface of the fixed plate 3. A shock-absorbing rubber sleeve 5 is fixedly sleeved inside the fixed box plate 2 on the side of the fixed plate 3. The shock-absorbing rubber sleeve 5 is sleeved on the outer surface of the fixed plate 3 and is configured as a hollow I-shape, so that the shock-absorbing rubber sleeve 5 can be locked inside the fixed box plate 2. When the fixed plate 3 swings horizontally left and right inside the shock-absorbing rubber sleeve 5, shock absorption and buffering can be performed by squeezing the shock-absorbing rubber sleeve 5, thereby protecting the fixed plate 3 from vibration and impact caused by vibration. The shock-absorbing rubber sleeve 5 is rotatably sleeved on the outside of the fixed plate 3. On the side, the inner diameter of the shock-absorbing rubber sleeve 5 is larger than the outer diameter of the fixed plate 3 inside it. The outer diameter of the shock-absorbing rubber sleeve 5 is equal to the outer diameter of the fixed plate 4. A fixed connecting plate 6 is fixed on the motor body 1 outside the output end of the motor body 1, so that the fixed plate 3 can drive the fixed connecting plate 6 to squeeze the shock-absorbing rubber sleeve 5 when it moves. A connecting base plate 14 is fixed to the bottom of the motor body 1 by bolts. A shock-absorbing rubber block 15 is glued to the bottom surface of the connecting base plate 14. A fixed bracket 16 is fixed to the bottom surface of the shock-absorbing rubber block 15. The bottom surface of the fixed bracket 16 is fixed to the top surface of the fixed base plate 13. The width of the shock-absorbing rubber block 15 is smaller than the width of the bottom surface of the connecting base plate 14 and the top surface of the fixed bracket 16. The bottom surface of the fixed base plate 13 is flush with the bottom surface of the fixed box plate 2. Several fixing holes are equally spaced on both sides of the fixed base plate 13 to facilitate fixing the fixed base plate 13 to the bottom surface.

[0023] As an optimization solution, such as Figure 1 , Figure 3 and Figure 5 As shown, a shock-absorbing ring 7 is fixed to the side of the fixed connecting plate 6 near the fixed box plate 2. Several support plates 9 are equidistantly arranged on the outer surface of the shock-absorbing ring 7. A fixing plate 10 is fixed to the outer side of each support plate 9 on the fixed box plate 2. Several sliding holes that mate with the first sliding rod 11 are equidistantly opened inside the fixing plate 10. A limiting cap with a diameter larger than the sliding hole is threaded onto one end of each first sliding rod 11 extending to the outer side of the fixing plate 10, facilitating the replacement of the second spring 12 and ensuring its service life. Each fixing plate... Several first slide rods 11 are slidably connected to the fixed plate 10. One end of each first slide rod 11, which extends through the inner side of the fixed plate 10, is fixed to the outer side of the support plate 9. A second spring 12 is sleeved on each of the first slide rods 11 between the support plate 9 and the fixed plate 10. Both ends of each second spring 12 abut against the support plate 9 and the fixed plate 10 respectively, which facilitates the replacement of the second spring 12. This ensures that the second spring 12 and the first spring 8 cooperate to push the motor body 1 to reset under the action of leveling, which facilitates the subsequent stable and accurate operation of the motor body 1.

[0024] Specifically, the inner diameter of the shock-absorbing ring 7 is larger than the outer diameter of the shock-absorbing rubber sleeve 5, ensuring that the shock-absorbing ring 7 can swing outside the shock-absorbing rubber sleeve 5. The thickness of the shock-absorbing rubber sleeve 5 extending to the inner end of the shock-absorbing ring 7 is equal to the thickness of the shock-absorbing ring 7. Each support plate 9 is set as a fan shape to cooperate with the shock-absorbing ring 7. The arc length of each support plate 9 is less than one-quarter of the arc length of the shock-absorbing ring 7, so that the support plates 9 can fit against the outer surface of the shock-absorbing ring 7. The thickness of each support plate 9 is equal to the thickness of the shock-absorbing ring 7, ensuring that the shock-absorbing ring 7 can squeeze the support plate 9 when it swings, thereby pushing the first slide rod 11 to compress the second spring 12 and move.

[0025] As an optimization solution, such as Figure 1 , Figure 3 and Figure 4 As shown, servo cylinders 17 are installed on the top surfaces of the fixed base plates 13 on both sides of the fixed bracket 16. Fixed rods 18 are fixed to the output ends of the two servo cylinders 17. The top edge of the fixed rods 18 is arc-shaped. Positioning sleeves 19 are fixed on both sides of the motor body 1 above the two fixed rods 18. Positioning holes that cooperate with the fixed rods 18 are opened inside the two positioning sleeves 19. When the motor body 1 drives the switch machine to run, the fixed rods 18 are inserted into the positioning sleeves 19 to limit the movement of the motor body 1, so that the motor body 1 can remain stable during operation.

[0026] As a further optimization scheme, such as Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, a connecting plate 21 is fixed on the side wall of the connecting base plate 14 on the side of each servo cylinder 17. A spacer plate 22 is fixed on the bottom surface of the connecting plate 21. Movable push plates 23 are attached to both sides of the spacer plate 22. Second slide rods 24 are symmetrically fixed on the outer side of each movable push plate 23. The second slide rods 24 are slidably sleeved inside the support base plate 20. A first spring 8 is sleeved on the second slide rod 24 between the outer side of each movable push plate 23 and the inner wall of the support base plate 20. The two ends of each first spring 8 abut against the movable push plate 23 and the support base plate 20 respectively.

[0027] Specifically, each support base plate 20 is U-shaped to facilitate support of the partition plate 22 and the movable push plate 23. The bottom of the support base plate 20 is fixed to the top surface of the fixed base plate 13 by bolts. The top surface of the support base plate 20 is located below the bottom surface of the connecting plate 21. Sliding holes that cooperate with the second slide rod 24 are provided on both sides of the support base plate 20. Each second slide rod 24 has a limit cover threaded on one end extending to the outside of the support base plate 20. The diameter of the limit cover is larger than the diameter of the sliding hole, which facilitates the replacement of the first spring 8 and ensures the service life of the first spring 8. The height of each movable push plate 23 is smaller than the height of the partition plate 22.

[0028] Working principle: When the motor body 1 drives the switch machine, the servo cylinder 17 operates, driving the fixed insertion rod 18 to move upward and insert into the positioning hole of the positioning sleeve 19, thereby positioning the motor body 1. When the switch machine finishes operating, the servo cylinder 17 operates, driving the fixed insertion rod 18 to move out of the positioning hole. At this time, the limitation of the fixed insertion rod 18 on the motor body 1 is released. When the train passes the motor body 1, the vibration generated by the train's movement acts on the fixed box plate 2 and the fixed base plate 13. When the fixed box plate 2 receives the vibration force and shakes, it pulls the shock-absorbing rubber sleeve 5. The deformation of the shock-absorbing rubber sleeve 5 absorbs part of the vibration force. At the same time, the fixed box plate 2 drives the fixed plate 10 to slide on the first slide rod 11. While sliding, the second spring 12 is compressed. The restoring force of the second spring 12 offsets part of the compressive force and further offsets part of the compressive force of the fixed box plate 2. The vibration force generated is used to protect the fixed plate 3 from shock. When the fixed base plate 13 receives the vibration force and shakes, it causes the fixed bracket 16 to shake. When the fixed bracket 16 shakes, it pulls the shock-absorbing rubber block 15, causing the shock-absorbing rubber block 15 to deform. The deformation of the shock-absorbing rubber block 15 absorbs part of the vibration force. When the fixed base plate 13 shakes, it causes the supporting base plate 20 to shake on the partition plate 22 and compresses the first spring 8. The restoring force of the second spring 12 offsets part of the vibration force, thereby protecting the motor body 1 from shock. After the train passes, the motor body 1 can return to its initial position under the push of the first spring 8 and the second spring 12, so that the positioning hole inside the positioning sleeve 19 is aligned with the fixed plug 18, so that when the motor body 1 runs again, the fixed plug 18 can be inserted into the positioning sleeve 19.
