Description

Technical Field

[0001] This utility model relates to the field of rail transit equipment technology, specifically to an interlocking controller for rail transit. Background Technology

[0002] The rail transit interlocking system is a core piece of equipment to ensure the safe operation of trains. Its function is to achieve coordinated linkage of track section occupancy detection, turnout position control, signal display and route arrangement through logic control, so as to ensure that trains travel safely along the predetermined path. It can also push the turnout to move according to the train's route, so that the turnout is connected to the corresponding track, and the train can travel on the correct track route.

[0003] However, existing interlocking controllers typically use a motor to drive a gear, which in turn moves a rack. The rack then pushes a control lever to extend or retract, thus achieving the horizontal movement of the turnout. During operation, the frequent meshing between the gear and rack causes the lubricating oil to drip and leak, resulting in significant wear on the gears. Maintenance personnel need to frequently add lubricating oil to the gear drive area, which is time-consuming, labor-intensive, and inconvenient for maintenance work. Utility Model Content

[0004] The purpose of this invention is to provide an interlocking controller for rail transit, which solves the problem that in the prior art, maintenance personnel usually need to frequently add lubricating oil to the gear drive position for maintenance, which is time-consuming and labor-intensive, and brings a lot of inconvenience to the maintenance work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an interlocking controller for rail transit, comprising:

[0006] A protective mechanism and a control mechanism and a drive mechanism respectively assembled inside the protective mechanism;

[0007] The protective mechanism includes a housing, and a maintenance cover is hinged to the top of the housing.

[0008] The control mechanism includes a support frame fixedly installed inside the housing, a movable block slidably installed inside the support frame, a control rod extending out of the housing fixedly installed on one side of the movable block, a first tooth fixedly installed on the top of the movable block, and a surrounding frame fixedly installed on the top of the movable block and at the outer periphery of the first tooth.

[0009] The driving mechanism includes a driving component fixedly installed inside the housing. A rotating wheel is installed at the output end of the driving component. The rotating wheel is in contact with the top of the frame. The surface of the rotating wheel is distributed with second teeth that mesh with the first teeth.

[0010] Furthermore, a protective cover is fixedly installed on the inner wall of the box, and the protective cover surrounds the outer periphery of the rotating wheel.

[0011] Furthermore, a flow guide block is fixedly installed on the inner wall of the protective cover, and the protective cover is fixedly installed to the box body through a fixing seat.

[0012] Furthermore, an observation window is provided on the top of the maintenance cover, and the maintenance cover is fixed to the box body by a fixing bolt.

[0013] Furthermore, mounting bases are fixedly installed at the four corners of the outer perimeter of the housing, and mounting holes are provided on the surface of the mounting bases.

[0014] Furthermore, the movable block and the support frame are slidably mounted together via a slider, the inner wall of the support frame is provided with a groove for the slider to slide, and a connecting seat is fixedly mounted on one end of the control rod.

[0015] Compared with the prior art, the interlocking controller for rail transit provided by this utility model, by setting up a control mechanism, can add lubricating oil into the enclosure. The enclosure can block the lubricating oil, so that the lubricating oil can always fill the tooth groove between the first teeth. It can maintain a continuous lubrication state during driving, reduce the loss of lubricating oil during frequent meshing driving, effectively reduce wear, avoid the trouble of frequent lubrication by maintenance personnel, and bring more convenience to maintenance work.

[0016] By installing a protective cover, the outer perimeter of the rotating wheel can be covered. During the rotation of the second tooth, the protective cover prevents lubricating oil from being splashed and dripping into the external space.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] As attached Figure 1 To be continued Figure 6 As shown:

[0028] Example 1:

[0029] This utility model provides an interlocking controller for rail transit, comprising:

[0030] The protective mechanism 1 and the control mechanism 2 and drive mechanism 3 respectively assembled inside the protective mechanism 1;

[0031] The protective mechanism 1 includes a housing 11, and a maintenance cover 12 is hinged to the top of the housing 11;

[0032] The control mechanism 2 includes a support frame 21 fixedly installed inside the housing 11. A movable block 23 is slidably installed inside the support frame 21. A control rod 24 extending out of the housing 11 is fixedly installed on one side of the movable block 23. A first tooth 25 is fixedly installed on the top of the movable block 23. A frame 26 is fixedly installed on the top of the movable block 23 and at the outer periphery of the first tooth 25.

[0033] The drive mechanism 3 includes a drive component 31 fixedly installed inside the housing 11. A rotating wheel 32 is installed at the output end of the drive component 31. The rotating wheel 32 is in contact with the top of the frame 26. The surface of the rotating wheel 32 is distributed with second teeth 33 that mesh with the first teeth 25.

[0034] As can be seen from the above, by fixing the box 11 at a suitable position near the track during use, and connecting the control rod 24 with the linkage mechanism of the turnout, the control rod 24 can be extended and retracted to push the turnout to move horizontally, which facilitates the interlocking operation between the turnout and the track.

[0035] The drive unit 31 is a motor that provides power to the rotating wheel 32, which rotates the wheel 32. The rotation of the wheel 32 drives the second tooth 33 to rotate. Through the meshing action between the second tooth 33 and the first tooth 25, the moving block 23 can be moved horizontally along the support frame 21. Through the movement of the moving block 23, the control lever 24 can be extended and retracted, which can realize the interlocking operation of the turnout. By adding lubricating oil into the enclosure 26, the loss of lubricating oil is reduced. The enclosure 26 can limit the lubricating oil and prevent it from dripping into the external space. The lubricating oil can always fill the groove between the first tooth 25, which can continuously lubricate the meshing position between the first tooth 25 and the second tooth 33. This can effectively reduce wear during the drive process, avoid the trouble of frequent lubrication by maintenance personnel, and bring more convenience to maintenance work.

[0036] When the rotating wheel 32 rotates, it can press against the top of the frame 26 and roll. The contact between the rotating wheel 32 and the frame 26 can keep the first tooth 25 and the second tooth 33 in a tight meshing state, making it less likely to loosen, and improving the precise control effect when the drive control lever 24 extends and retracts.

[0037] From the appendix Figure 1 and attached Figure 6 It can be seen that a protective cover 4 is fixedly installed on the inner wall of the box 11, and the protective cover 4 is wrapped around the outer periphery of the rotating wheel 32.

[0038] As can be seen from the above, during the rotation of the second tooth 33 driven by the rotating wheel 32, the protective cover 4 can cover the outer periphery of the rotating wheel 32. During the rotation of the second tooth 33 driven by the rotating wheel 32, the protective cover 4 can prevent the lubricating oil from being carried up and splashing into the external space. The splashed lubricating oil can drip back into the frame 26 along the inner wall of the protective cover 4 for reuse, which can effectively reduce the waste of resources and improve the use effect.

[0039] For details, please refer to the appendix. Figure 6As shown, a flow guide block 41 is fixedly installed on the inner wall of the protective cover 4, and the protective cover 4 is fixedly installed with the box body 11 through a fixing seat 42.

[0040] As can be seen from the above, the inclined inner wall of the guide block 41 can guide the lubricating oil that slides down the inner wall of the protective cover 4, and can guide the lubricating oil into the range of the frame 26, so that the lubricating oil can be guided into the inside of the frame 26 for recycling, which is convenient for recycling and avoids the lubricating oil from sliding into the external space and causing waste.

[0041] For details, please refer to the appendix. Figure 1 and attached Figure 2 As shown, the top of the maintenance cover 12 is provided with an observation window 14, and the maintenance cover 12 is fixed to the box body 11 by a fixing bolt 13.

[0042] As can be seen from the above, by opening the maintenance cover 12, maintenance personnel can easily perform maintenance operations on the parts in the drive mechanism 3 and control mechanism 2 inside the housing 11. By closing the maintenance cover 12, the top of the housing 11 can be easily sealed to prevent impurities from the external environment from entering the housing 11. The maintenance cover 12 can be easily fixed by rotating the fixing bolt 13 to prevent it from being opened accidentally. Because the observation window 14 is transparent, the operating status of the drive mechanism 3 and control mechanism 2 inside the housing 11 can be easily observed without opening the maintenance cover 12, which facilitates troubleshooting and brings more convenience to the maintenance work.

[0043] Working principle: By connecting the control lever 24 to the interlocking structure of the turnout, the drive component 31 drives the rotating wheel 32 to rotate, causing the second tooth 33 to rotate synchronously with the rotating wheel 32. The meshing between the second tooth 33 and the first tooth 25 drives the moving block 23 to move along the support frame 21. The forward and reverse rotation of the rotating wheel 32 causes the moving block 23 to extend and retract the control lever 24. This extension and retraction of the control lever 24 controls the movement of the turnout, facilitating turnout docking. The lubricating oil is intercepted and blocked by the frame 26, ensuring that it remains within the groove between the first tooth 25. This provides continuous lubrication to the meshing position between the first tooth 25 and the second tooth 33. During the meshing transmission, the protective cover 4 prevents the lubricating oil from splashing to the outside, allowing it to slide back down into the frame 26 for recycling, thus maintaining the lubrication effect between the first tooth 25 and the second tooth 33.

[0044] Example 2:

[0045] Reference Appendix Figure 2As shown, mounting bases 15 are fixedly installed at the four corners of the outer perimeter of the housing 11, and mounting holes 16 are provided on the surface of the mounting bases 15.

[0046] As can be seen from the above, by using bolts to pass through the mounting holes 16, the mounting base 15 can be easily fixed to the ground next to the track, which can facilitate the installation and fixation of the box 11 and prevent the box 11 from shifting.

[0047] Reference Appendix Figure 3 and attached Figure 4 As shown, the movable block 23 is slidably installed with the support frame 21 via a slider 28. The inner wall of the support frame 21 is provided with a groove 22 for the slider 28 to slide. One end of the control rod 24 is fixedly installed with a connecting seat 27.

[0048] As can be seen from the above, the slider 28 can slide along the slide groove 22. The slide groove 22 limits the slider 28, so that the moving block 23 will not fall out of the support frame 21. The support frame 21 can support the moving block 23, and at the same time, the moving block 23 can maintain a stable state during the movement, so that the moving block 23 is not easy to shake.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
