Description

Technical Field

[0001] This invention relates to the field of straddle-type monorail transportation technology, and in particular to a translational single turnout. Background Technology

[0002] Straddle-type monorail travel has become an important component of urban rail transit development. Straddle-type monorails offer numerous advantages, including moderate capacity, high speed, low cost, good environmental adaptability, low noise, and strong climbing ability. Among these advantages, the straddle-type monorail system relies heavily on turnout technology. In straddle-type monorail systems, the sliding single turnout can be used to adjust the direction of vehicle travel and switch the vehicle's track under the control of the dispatcher.

[0003] Currently, the sliding single turnout structure is relatively bulky and has low reliability. It is prone to numerous failure points during operation, making timely repairs difficult and impacting normal train operation. Furthermore, the turnout beam exhibits a certain degree of tailing during the switching operation, increasing the error during switching, raising the actual operating conditions of the locking device, and reducing the reliability and lifespan of both the switching and locking devices. Because the switching device is rigidly connected to the turnout beam, it requires a suitable installation site. After prolonged operation, the turnout switching process may experience idle rotation of the switch wheel, further reducing the turnout's reliability and stability, and increasing the maintenance and operating costs of the sliding single turnout. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this patent application provides a translational single turnout. It employs an elastic drive device and a dual guide device to solve the tailing phenomenon of the turnout beam and the freewheeling phenomenon of the drive wheel during the switching operation of the translational single turnout, thereby improving the reliability and maintainability of the translational single turnout, improving the actual operating conditions of the locking device, extending the service life of the switching device and locking device components, and enhancing the reliability of the turnout equipment. Simultaneously, the guide device structure is optimized, improving the operational and maintenance work space environment and enhancing maintainability.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A translational single turnout includes a turnout beam, a trolley, a guiding device, a locking device, and a driving device;

[0007] The turnout beam includes a straight beam and a curved beam. The end with the smaller horizontal distance between the straight beam and the curved beam is designated as the small end of the turnout beam, and the other end as the large end. The trolley includes a first frame and a second frame. The first frame is located on the small end side of the turnout beam, and the second frame is located on the large end side. The guiding device includes at least two guiding units, which are installed below the turnout beam and move with it. Each guiding unit has at least two guiding points. The locking device includes three first locking units and two second locking units. The first and second locking units have identical structures. The three first locking units are installed on the small end side of the turnout beam, and the two second locking units are installed on the large end side. At least one of the three first locking units locks the turnout beam, and at least one of the two second locking units locks the turnout beam. The driving device is located between the turnout beam and the running rail. The driving device includes four driving units, which are elastically connected to the bottom of the turnout beam. The driving device is used to drive the turnout beam to complete the turning and retraction actions on the running rail.

[0008] Preferably, the drive unit includes a drive motor, an elastic unit, and rollers. The drive motor drives the rollers to travel on the track. The rollers are embedded in the elastic unit, which is mechanically connected to the turnout beam.

[0009] Preferably, the elastic unit includes a traveling frame, the rollers are embedded in the traveling frame, and the upper end of the traveling frame is connected to the turnout beam through an elastic component.

[0010] Preferably, the elastic component is a spring, and the elastic component is provided with at least four springs.

[0011] Preferably, the elastic component is an elastic cylinder or an elastic hydraulic cylinder.

[0012] Preferably, the roller is made of a rigid material or a rubber wheel.

[0013] Preferably, the guiding unit includes an adjustable device, a guide wheel, and a guide rail. The adjustable device is fixed directly below the turnout beam, the guide wheel is mounted on the adjustable device, and the adjustable device is used to adjust the distance between the guide wheel and the guide rail.

[0014] Preferably, there are two or more guide points between the guide wheel and the guide rail, and the adjustable device has an adjustment distance of 5 mm or more.

[0015] Preferably, both the first locking unit and the second locking unit include a linear electric rod and a T-shaped flipping mechanism. The T-shaped flipping mechanism is connected to the linear electric rod, and the linear electric rod is used to push the T-shaped flipping mechanism to lock the turnout beam or pull the T-shaped flipping mechanism to unlock the turnout beam.

[0016] Preferably, it also includes a control device and an intelligent detection device; the control device is used to control the locking device and the driving device, and the intelligent detection device is set in the control device to detect and diagnose the status and fault type of the translational single turnout, and send fault signals to the control center to complete the networked and information-based management of the turnout equipment.

[0017] In summary, this translational single turnout has the following beneficial effects:

[0018] 1. The flexible drive unit avoids the idle rotation of the turnout drive rollers, enhancing the stability and reliability of the turnout equipment. The drive unit also adopts a modular design, which facilitates maintenance and repair.

[0019] 2. Two guiding devices are installed at both ends of the turnout beam, and two guiding points are set at each end of the turnout beam. This effectively avoids the tailing phenomenon of the turnout beam during the switching process, reduces the switching error, improves the actual working condition of the locking device, increases the service life of the components, and enhances the reliability of the turnout equipment.

[0020] 3. Three first locking units are installed at the small end of the turnout beam, and two second locking units are installed at the large end, with each locking unit operating independently. If any one of the three first locking units at the small end of the turnout beam fails, the other first locking units can still operate normally. Similarly, if one of the two second locking units at the large end of the turnout beam fails, the other second locking unit can still operate normally. Furthermore, if either one of the first locking units at the small end or either one of the second locking units at the large end of the turnout beam fails, the other first and second locking units can still operate normally, ensuring the normal operation of the sliding single-opening turnout.

[0026] like Figure 1-4 As shown, a translational single turnout includes a turnout beam 4, a trolley 5, a guide device 1, a locking device 2, and a drive device 3, as well as a control device 6 and an intelligent detection device.

[0027] The turnout beam 4 includes a straight beam and a curved beam. The end with the smaller horizontal distance between the straight and curved beams is designated as the small end of the turnout beam, and the other end as the large end. The curved beam has a radius of curvature of 50 meters, and both the straight and curved beams are 850 millimeters wide. The trolley 5 includes a first frame 51 and a second frame 52. The first frame 51 is located on the small end side of the turnout beam and has two parallel guide rails. The second frame 52 is located on the large end side of the turnout beam and also has two parallel guide rails. The guiding device 1 is used to prevent the turnout beam 4 from tailing. The guiding device 1 includes at least two guiding units, which are installed below the turnout beam 4 and move with it. Each guiding unit has at least two guiding points. The locking device 2 includes three first locking units 21, 22, and 23 and two second locking units 24 and 25. The structure of the first locking unit 3 is the same as that of the second locking unit 22. Three first locking units 21 are installed on one side of the small end of the turnout beam 4, located between the first frame 51 and the guide unit. Two second locking units 24 and 25 are installed on one side of the large end of the turnout beam 4, located between the second frame 52 and the guide unit. Of the three first locking units 21, 22, and 23, at least one locks the turnout beam 4. Of the two second locking units 24 and 25, at least one locks the turnout beam 4. The locking device 2 is used to fix the turnout beam 4 after it completes the switching action, preventing it from moving left or right, to ensure the normal passage of vehicles through the turnout area. The drive device 3 is located between the turnout beam 4 and the running rail. The drive device 3 includes four drive units, which are elastically connected to the bottom of the turnout beam 3. The drive device is used to drive the turnout beam 3 to complete the switching and retraction actions on the running rail. Furthermore, the guide device 1, locking device 2, drive device 3, and trolley 5 are all modularly designed, facilitating maintenance personnel to maintain the equipment and repair malfunctions. Control device 6 controls the locking device 2 to lock and unlock the turnout beam 4, and also controls the drive device 3 to drive the turnout beam 4 to complete the switching action. An intelligent detection device is installed in the control device to detect and diagnose the status and fault type of the sliding single turnout, and sends fault signals to the control center, completing the networked and information-based management of the turnout equipment. This achieves remote real-time monitoring of the overall performance parameters of the turnout equipment, remote self-diagnosis of electrical faults in the turnout equipment, and predictive maintenance of important components, realizing systematic networked management of all turnout equipment on the line and effectively improving the efficiency of daily line maintenance.

[0028] This translational single-opening turnout structure features lightweight structural components, high reliability, and a dual-guide structure that reduces equipment vibration and optimizes the system structure. The turnout beam 4 and the trolley 5 are separately positioned, reducing potential failure points and facilitating daily maintenance of the drive unit 3. The locking device 2 employs a flip-guide roller locking technology, ensuring safety and reliability with fewer potential failure points. This improves the actual working conditions of the locking device 2, extends the service life of the components, and enhances the maintainability and reliability of the turnout equipment, making it more suitable for airport rapid transit systems, tourist routes, and other applications.

[0029] In this embodiment, two guide units are provided, namely the first guide unit 11 and the second guide unit 12, which are respectively located near the small end and the large end of the turnout beam 4. Each guide unit is provided with two guide points.

[0030] When implementing, such as Figure 4 As shown, the drive unit includes a drive motor 311, an elastic unit 312, and a roller 313. The drive motor 311 is used to drive the roller 313 to move on the track. The roller 313 is embedded in the elastic unit 312, and the elastic unit 312 is mechanically connected to the turnout beam 4.

[0031] The four drive units are the first drive unit 31, the second drive unit 32, the third drive unit 33 and the fourth drive unit 34. The first drive unit 31 and the second drive unit 32 are located on one side of the small end of the turnout beam 4, and the third drive unit 33 and the fourth drive unit 34 are located on one side of the large end of the turnout beam 4.

[0032] The first drive unit 31 is located directly below the curved beam on one side of the small end of the turnout beam 4;

[0033] The second drive unit 32 is located directly below the straight beam on one side of the small end of the turnout beam 4;

[0034] The third drive unit 33 is located directly below the curved beam on one side of the turnout beam 4.

[0035] The fourth drive unit 34 is located directly below the straight beam on one side of the large end of the turnout beam 4.

[0036] When any one of the first drive unit 31 and the second drive unit 32 fails or stops working, or when any one of the third drive unit 33 and the fourth drive unit 34 fails or stops, the turnout beam 4 can complete the switching action. The drive device 3 drives the turnout beam 4 on the trolley 5 to complete the switching action through drive rollers.

[0037] During the operation of a single-turn turnout with a sliding mechanism, gaps may exist between the drive unit 3 and the running rail due to various reasons. This causes the drive wheel of the turnout beam 4 to spin freely during the switching process, which not only damages the service life of the motor but also reduces the stability and reliability of the turnout equipment. In this application, an elastic unit 312 is added to the drive unit 3. If there is a gap between the drive unit 3 and the running rail, the elastic unit 312 will increase the vertical distance between itself and the turnout beam 4, thereby eliminating the gap between the drive unit 3 and the running rail. This increases the adaptability of the turnout equipment to the operating site, avoids the idling of the drive wheel, and improves the reliability and ease of maintenance of the equipment.

[0038] When any one of the first drive unit 31 and the second drive unit 32 fails, or when any one of the third drive unit 33 and the fourth drive unit 34 fails, the turnout beam 4 can complete the switching action.

[0039] In practice, the elastic unit 312 includes a traveling frame, with rollers 313 embedded in the traveling frame, and the upper end of the traveling frame is connected to the turnout beam 4 through an elastic component.

[0040] In implementation, the elastic component is a spring, and at least four springs are provided. The vertical distance between the elastic unit 312 and the turnout beam 4 can be adjusted by the springs.

[0041] In practice, the elastic component is either an elastic air cylinder or an elastic hydraulic cylinder.

[0042] In practice, roller 313 is made of rigid material or rubber.

[0043] When implementing, such as Figure 2 As shown, the guiding unit includes an adjustable device 111, a guide wheel 112, and a guide rail 113. The adjustable device 111 is fixed directly below the turnout beam 4, and the guide wheel 112 is mounted on the adjustable device 111. The adjustable device 111 is used to adjust the distance between the guide wheel 112 and the guide rail 113. During the movement of the turnout beam 4, there can be a certain gap between the guide wheel 112 and the guide rail 113, or it can be close to the guide rail 113.

[0044] There are two or more guide points between the guide wheel 112 and the guide rail 113, and the adjustable device 111 can adjust the distance by 5 mm or more. The adjustable device 111 can adjust the distance between the guide wheel and the guide rail manually; the adjustable device 111 can also adjust the distance between the guide wheel 112 and the guide rail 113 by any one or more combinations of electric, hydraulic, and software control devices.

[0045] When the turnout beam 4 is performing a switching motion, since the guide device 1 is mechanically connected to the turnout beam 4, when the speed difference between the driving devices 3 at both ends of the turnout beam 4 or the switching trajectory reaches a certain threshold, the guide wheel 112 in the guide device 1 and the guide rail 113 generate a reaction force to correct the trajectory distance difference between the two ends of the turnout beam 4. This corrects the tailing phenomenon of the turnout beam 4 during the switching action of the translational single turnout, improves the actual working conditions of the locking device, increases the service life of the switching device and locking device components, and enhances the reliability and stability of the turnout equipment.

[0046] When implementing, such as Figure 3 As shown, the first locking units 21, 22, and 23 and the second locking units 24 and 25 each include a linear electric rod 211 and a T-shaped flipping mechanism 212. The T-shaped flipping mechanism 212 is connected to the linear electric rod 211. The linear electric rod 211 is used to push the T-shaped flipping mechanism 212 to lock the turnout beam 4 or pull the T-shaped flipping mechanism 212 to unlock the turnout beam 4, preventing the turnout beam 4 from moving left or right.

[0047] The three first locking units 21, 22, and 23 and the two second locking units 24 and 25 are independent of each other. If any one of them fails, or if any one of the first locking units 21, 22, and 23 or any one of the second locking units 24 and 25 fails, the sliding single turnout can still operate normally and ensure the normal operation of the monorail system. If a fault occurs, the intelligent monitoring system will send the cause of the fault to the control center, so that maintenance personnel can understand the cause of the fault and take corresponding maintenance measures in advance. This not only improves the maintainability of the turnout equipment, but also enhances its reliability.

[0048] In a sliding single turnout, if there is no guide device 1 or only one guide device 1, when the turnout beam 4 performs the switching action, because the switch device 3 is driven by a motor, the movement distance between the large and small ends of the turnout beam 4 may not be exactly the same, causing a certain degree of tailing phenomenon in the turnout beam 4. This leads to inconsistent force directions on the drive wheels during the drive of the turnout beam 4 by the drive device 3, increasing the friction between the drive wheels and the trolley 5. The greater the difference in movement distance between the two ends of the turnout beam 4, the greater the friction between the drive wheels and the trolley 5. After the turnout has been in operation for a period of time, the drive wheels under the drive device and the rails on the trolley 5 must be replaced. At the same time, it will also cause a positioning deviation between the locking device 2 and the turnout beam 4. If the positioning deviation is large, the output torque of the locking device 2 will exceed the rated torque of the motor, resulting in the turnout beam 4 being unable to be locked. The control device 6 will trigger a fault and transmit a signal to the control center, affecting the normal operation of the line and reducing the reliability of the sliding single turnout equipment.

[0049] like Figure 1As shown, when two guide devices 1 are set in a sliding single turnout, if the movement distances of the large and small ends of the turnout beam 4 are inconsistent during the movement of the turnout beam 4, the horizontal force between the multiple guide wheels 112 and the guide rail 113 in the guide device 1 will increase, the force between different drive units in the drive device 3 will be different, and the output power of the drive motor 311 will also change accordingly. This will keep the movement distances of the large and small ends of the turnout beam 4 consistent, reduce the tailing phenomenon of the turnout beam 4, reduce the error during the switching of the sliding single turnout and the actual working conditions of the locking device 2, increase the reliability and service life of the switching device 3 and the locking device 2, and thus improve the overhaul period of the sliding single turnout equipment to a certain extent, and reduce the use, maintenance and operation costs of the sliding single turnout.

[0050] Furthermore, when two or more guide devices 1 are installed in a translational single turnout, the guide device 1 can also be installed in the middle position of the turnout beam 4. If the turnout beam 4 exhibits tailing phenomenon during the switching process, the guide device can eliminate the tailing phenomenon during the switching process of the turnout beam 4.

[0051] Finally, it should be noted that those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this invention also intends to include these modifications and variations.
