单开关节可挠型道岔挠曲装置及单开关节可挠型道岔Single switch section flexible turnout flexure device and single switch section flexible turnout

技术领域Technical field

本公开涉及轨道交通技术领域，特别是涉及一种单开关节可挠型道岔挠曲装置及单开关节可挠型道岔。The present disclosure relates to the field of rail transit technology, and in particular to a single-switch section flexible track ball deflection device and a single-switch section flexible track switch.

背景技术Background technique

相关技术中，方案一提出了一种跨坐式单轨交通轨道可挠式道岔梁，包括用于组成可挠道岔梁的可挠梁段和用于驱动可挠道岔梁发生挠度变形的挠度驱动组件，可挠梁段包括可挠梁主体和行走支撑；采用强制挠性变形的可挠梁段组成可挠道岔梁结构，在需要与轨道变换接合时通过外力驱动发生挠度变形，可挠梁段的导向面和稳定面均平滑过渡，消除折线，利于轻轨列车通行，并且结构与现有道岔结构相比具有较大幅度简化，降低制造成本和缩短制造工期，使用寿命较长，节约使用和维护成本，能够保证轻轨行驶的舒适性和安全性，并降低车辆行走噪声，具有较好的环保性。In the related art, the first solution proposes a straddle-type monorail traffic track flexible ballast beam, comprising a flexible beam segment for forming a flexible ballast beam and a deflection driving component for driving the deflection of the flexible ballast beam. The flexible beam section includes the flexible beam body and the walking support; the flexible beam section adopting the forced flexural deformation constitutes the flexible track truss beam structure, and the deflection is driven by the external force when the need for the orbital transformation is required, and the flexible beam section is Both the guiding surface and the stable surface are smoothly transitioned, eliminating the folding line, facilitating the passage of the light rail train, and the structure is greatly simplified compared with the existing ballast structure, reducing the manufacturing cost and shortening the manufacturing period, and the service life is long, saving the use and maintenance cost. It can ensure the comfort and safety of light rail driving, and reduce vehicle walking noise, and has better environmental protection.

其中，方案一中的驱动装置采用单电机输入多驱动臂输出的串行传动机构，挠曲装置采用多连杆串行联接机构，具有一定的不足：其一，转辙后的线形完全依赖于驱动臂的长度尺寸精度及其安装位置尺寸链配合精度，零部件加工和安装精度要求高，现场安装调试困难、不便精调。其二，多个减速箱间通过单一传动轴连接，传动距离长，且不同减速箱之间输入轴有一定夹角，需要联轴器补偿的轴交角大于一般同轴联轴器的使用范围。其三，上述机构原理导致转辙过程中道岔梁体运动速度波动较大，整体负载波动变化大，机构运行存在较大冲击，运动件疲劳寿命低。其四，挠曲构件布局，使得多数中间传动连杆为压力杆，易产生压杆失稳现象，为了避免失稳，多数杆件须选用大截面尺寸，在本就狭小的梁体内部空间下，需要较大的安装空间，大大增加了安装难度，也不利于设备的轻量化和降本。其五，螺纹形端面凸轮加工精度、制造成本要求高，不便润滑，维护难度大，而且凸轮与滚子直面接触，后期磨损后无法补偿，过大的间隙会引起严重的冲击，甚至会导致挠曲变形不到位。其六，凸轮轴安装轴为一等直径的光轴，与道岔梁梁体、凸轮轴配合面长，现场安装困难，加工精度高、成本高。Among them, the driving device in the first scheme adopts a serial transmission mechanism in which a single motor inputs multiple driving arms, and the flexing device adopts a multi-link serial coupling mechanism, which has certain disadvantages: First, the linear shape after the turning is completely dependent on The length dimension accuracy of the driving arm and the mounting position dimension chain matching precision, the parts processing and installation precision requirements are high, the on-site installation and debugging is difficult, and it is inconvenient to fine-tune. Second, a plurality of reduction gearboxes are connected by a single transmission shaft, the transmission distance is long, and the input shafts of different speed reduction boxes have a certain angle, and the axle intersection angle required for the coupling compensation is greater than the use range of the general coaxial coupling. Thirdly, the above-mentioned mechanism principle leads to large fluctuations in the movement speed of the ballast beam during the transition process, large fluctuations in the overall load, large impact on the operation of the mechanism, and low fatigue life of the moving parts. Fourth, the layout of the flexural members makes most of the intermediate transmission links be pressure bars, which tends to cause instability of the compression bars. In order to avoid instability, most of the bars must use large cross-sectional dimensions, which are under the narrow internal space of the beam. It requires a large installation space, greatly increasing the difficulty of installation, and is not conducive to the weight reduction and cost reduction of the device. Fifthly, the thread-shaped end face cam has high processing precision and manufacturing cost, is inconvenient to lubricate, and is difficult to maintain, and the cam and the roller are in direct contact with each other, and cannot be compensated after the wear in the later stage, and excessive clearance may cause serious impact, and may even cause scratching. The distortion is not in place. Sixth, the camshaft mounting shaft is an optical axis of equal diameter, which has a long mating surface with the ballast beam body and the camshaft, is difficult to install on site, has high processing precision and high cost.

方案二提出了用于跨座式单轨交通线路中使用的一种特殊轨道转换的关节可挠型道岔挠曲装置，包括导向面板、稳定面板、安装支座、凸轮支撑轴、轴向凸轮、双插头连杆、滚子装配、连杆副、电动推杆，挠曲装置采用凸轮拉杆串行联接的驱动形式实现导向面和稳定面的同步弯曲，导向面板和稳定面板通过铰制孔连接于双叉头拉杆两端，双叉形头拉杆与从动组件连接，从动组件再与圆柱凸轮机构接触相连，上方的两相邻圆柱凸轮机构之间以及上下对应的两圆柱凸轮机构之间通过连杆相连，当电动推杆启动推拉时；拉杆带动导向板实现横向同步移动，从而完成导向板的横向的横向弯曲。 Scheme 2 proposes a special track-switching joint flexible ballast deflection device for use in a straddle monorail traffic line, including a guide panel, a stabilizing panel, a mounting bracket, a cam support shaft, an axial cam, and a double The plug connecting rod, the roller assembly, the connecting rod pair and the electric push rod, the flexing device adopts the driving form of the serial connection of the cam pull rod to realize the synchronous bending of the guiding surface and the stabilizing surface, and the guiding panel and the stabilizing panel are connected to the double through the reaming hole Both ends of the fork pull rod, the double fork head pull rod is connected with the driven assembly, the driven assembly is in contact with the cylindrical cam mechanism, and the upper two adjacent cylindrical cam mechanisms and the upper and lower corresponding two cylindrical cam mechanisms are connected The rods are connected when the electric push rod is pushed and pulled; the pull rod drives the guide plates to realize lateral synchronous movement, thereby completing lateral lateral bending of the guide plates.

上述技术方案只是用圆柱凸轮和滚子代替了前述技术方案中的螺纹形端面凸轮和与之相配合的驱动滑槽，并没有克服前述技术方案中挠曲装置的缺陷，另外，上述技术方案中的道岔线形复杂，挠曲***调试困难。The above technical solution only replaces the thread-shaped end face cam in the foregoing technical solution with the driving chute in the foregoing technical solution by using the cylindrical cam and the roller, and does not overcome the defects of the flexing device in the foregoing technical solution. In addition, in the above technical solution, The turnout is complex and the deflection system is difficult to debug.

方案三提出了一种跨座式单轨关节型单开道岔驱动装置，主要由主电机、主减速机、转辙减速箱、手动转辙减速箱及转动臂组成，四个转辙减速箱通过传动轴及鼓形齿联轴器串联，并在4号梁下与主减速机相连，主减速机通过离合机构与主电机相连，手动转辙减速箱通过离合机构与道岔2号梁下的一个转辙减速箱相连，转辙减速箱上连接有转动臂，转动臂末端的滚轮位于道岔梁的滑槽内。转辙的同步性好，转辙精确可靠，故障率低，整个装置成本低。然而，方案三与方案一采用相同的驱动装置的布置形式，并没有克服方案一中驱动装置的缺陷。 Scheme 3 proposes a straddle-type single-track joint type single-turn turnout drive device, which is mainly composed of a main motor, a main reducer, a turn-by-turn reducer, a manual turn-by-turn reducer and a rotating arm, and four turn-by-turn reducers pass through the drive. The shaft and the drum-shaped toothed coupling are connected in series, and are connected to the main reducer under the No. 4 beam. The main reducer is connected to the main motor through the clutch mechanism, and the manual transfer reducer passes through the clutch mechanism and a turn under the No. 2 beam of the switch. The 辙 gearbox is connected, and the turning arm is connected to the turning gear box, and the roller at the end of the rotating arm is located in the chute of the ballast beam. The synchronization of the switch is good, the turn is accurate and reliable, the failure rate is low, and the cost of the whole device is low. However, the arrangement of the same driving device is adopted in the third embodiment and the first embodiment, and the defects of the driving device in the first embodiment are not overcome.

下面结合附图描述根据本公开实施例的单开关节可挠型道岔挠曲装置100。A single-switch section flexible ballast flexing device 100 in accordance with an embodiment of the present disclosure is described below in conjunction with the drawings.

如图1-图10所示，根据本公开实施例的单开关节可挠型道岔挠曲装置100，道岔挠曲装置100包括至少一个第一挠曲组1以及驱动第一挠曲组1的驱动组件2。As shown in FIGS. 1-10, a single-switch section flexible ballast flexing device 100 according to an embodiment of the present disclosure includes at least one first flexure set 1 and a first flexure set 1 Drive component 2.

例如，在图1的示例中，单开关节可挠型道岔挠曲装置100包括驱动组件2和沿前后方向布置的六个第一挠曲组1，驱动组件2可以驱动第一挠曲组1。第一挠曲组1的具体个数以及布置方式可以根据实际需要适应性设置，本公开对此不作具体限定。For example, in the example of FIG. 1, the single-switch section flexible turnout flexure device 100 includes a drive assembly 2 and six first flex groups 1 disposed in the front-rear direction, and the drive assembly 2 can drive the first flex group 1 . The specific number and arrangement of the first flexing group 1 can be adaptively set according to actual needs, which is not specifically limited in the present disclosure.

参照图1和图2，第一挠曲组1包括上、下两个第一挠曲结构11，每个第一挠曲结构11均包括第一挠曲推杆113和第一轴向凸轮112。Referring to FIGS. 1 and 2, the first flexure set 1 includes upper and lower two first flex structures 11, each of which includes a first flexure pusher 113 and a first axial cam 112. .

例如，每个第一挠曲组1包括上、下两个第一挠曲结构11，每个第一挠曲结构11均包括第一支撑轴111、第一轴向凸轮112、以及第一挠曲推杆113，第一轴向凸轮112可转动地支撑于第一支撑轴111上，第一挠曲推杆113可沿竖向移动地支撑于第一支撑轴111上。For example, each first flexure group 1 includes upper and lower two first flex structures 11, each of which includes a first support shaft 111, a first axial cam 112, and a first flexure The curved push rod 113, the first axial cam 112 is rotatably supported on the first support shaft 111, and the first flexing push rod 113 is vertically movably supported on the first support shaft 111.

全部的第一轴向凸轮112同步转动，也就是说，如果是多个第一挠曲组1，每个第一挠曲组1中的上、下挠曲结构11中的第一轴向凸轮112同步转动。All of the first axial cams 112 rotate synchronously, that is, if there are a plurality of first flexure groups 1, the first axial cams in the upper and lower flex structures 11 in each of the first flexure groups 1 112 synchronous rotation.

参照图3至图5并结合图1，第一挠曲结构11中，第一轴向凸轮112的周面上具有凸轮槽1121，第一挠曲推杆113上设有滚轮1131，滚轮1131伸入凸轮槽1121，滚轮1131与凸轮槽1121内底面可以间隔开预定距离，滚轮1131的周面为锥面形状，凸轮槽1121的形状与滚轮1131相适配。例如，凸轮槽1121的侧面为与滚轮1131的周面相切的曲面。由此，采用具有锥形周面的滚轮1131，通过调整滚轮1131安装高度，即可调整滚轮1131与凸轮槽1121之间的间隙，避免了冲击和挠曲不到位等危险现象的发生，在对安全性和稳定性要求日益增加的单轨交通领域前景广阔。Referring to FIG. 3 to FIG. 5 and FIG. 1 , in the first flexural structure 11 , the first axial cam 112 has a cam groove 1121 on the circumferential surface thereof, and the first flexing push rod 113 is provided with a roller 1131 and a roller 1131 extending. Into the cam groove 1121, the roller 1131 and the bottom surface of the cam groove 1121 may be spaced apart by a predetermined distance, the circumferential surface of the roller 1131 is tapered, and the shape of the cam groove 1121 is adapted to the roller 1131. For example, the side surface of the cam groove 1121 is a curved surface that is tangent to the circumferential surface of the roller 1131.

参照图7并结合图1至图6，根据本公开第二方面实施例的单开关节可挠型道岔200，包括：多节道岔梁210、道岔挠曲装置、驱动装置230以及中央控制***。Referring to Figure 7 in conjunction with Figures 1 through 6, a single-switch section flexible track 200 in accordance with an embodiment of the second aspect of the present disclosure includes a multi-section truss 210, a ballast flexure, a drive 230, and a central control system.

例如，道岔梁210安装有挠曲板220(包括导向挠曲板和稳定挠曲板)；道岔挠曲装置至少部分位于道岔梁210的内侧，道岔挠曲装置为上述的单开关节可挠型道岔挠曲装置100；驱动装置230设在道岔梁210的底部；中央控制***分别与驱动组件2和驱动装置230信号沟通。由此，易于通过中央控制***实现对单开关节可挠型道岔200的相应控制。For example, the ballast beam 210 is mounted with a flexure plate 220 (including a guide flexure plate and a stable flexure plate); the ballast flexure device is at least partially located inside the ballast beam 210, and the ballast flexure device is a single switch segment flexible type as described above The switch flexure device 100; the drive device 230 is disposed at the bottom of the ballast beam 210; the central control system is in signal communication with the drive assembly 2 and the drive device 230, respectively. Thereby, the corresponding control of the single-switch section flexible ballast 200 is easily achieved by the central control system.

挠曲推杆(包括第一挠曲推杆113和第二挠曲推杆413)的两端分别与对应的挠曲板220铰接。挠曲推杆通过耳座、销轴支撑在道岔梁210两侧的挠曲板220上。通过挠曲推杆可以进一步带动挠曲板220发生挠曲变形。Both ends of the flexing push rod (including the first flexing push rod 113 and the second flexing push rod 413) are respectively hinged with the corresponding flexing plate 220. The flexing push rod is supported on the flexure plate 220 on both sides of the ballast beam 210 through the ear seat and the pin shaft.

轴向圆柱凸轮组件(包括例如第一轴向凸轮112)通过支撑轴安装于道岔梁210的内侧，并且支撑轴为阶梯轴。便于单开关节可挠型道岔挠曲装置100的安装且有利于降低成本。An axial cylindrical cam assembly (including, for example, the first axial cam 112) is mounted to the inside of the ballast beam 210 by a support shaft, and the support shaft is a stepped shaft.

When the central control system issues a deflection deformation command, the driving member 22, for example, the movable push rod of the electric push rod (or hydraulic cylinder) protrudes, and on the other hand, passes through the intermediate link transmission structure to drive the upper and lower axial cylinders in the ballast beam 210. The cam assembly rotates clockwise, so that the flexing push rod (for example, the first flexing push rod 113) pushes the guiding flexure plate and the stable flexing plate to generate an approximately circular arc deflection deformation, and on the other hand, the second pull rod 51 and the second The three pull rods 53 drive the flexing push rods (for example, the second flexing push rods 413) in the adjacent ballast beams 210 to push the guiding flexure plates and the stable flexure plates to produce the same deflection; when the deflection is in place, the center The control system issues a position hold command, and the movable push rod of the electric push rod remains stationary at the corresponding position, that is, the flexing push rod does not move at the designated position; when the monorail train passes, the central control system issues a reset command, the activity of the electric push rod The push rod is retracted, thereby driving the flexing push rod back to the initial position, and the guiding flexure plate and the stable flexing plate are restored to a straight state.

Thereby, a reliable connection between the vertical shaft 242 and the horizontal shaft 241 can be achieved, and the torque can be transmitted.

例如，T形轴240包括横轴241、竖轴242和平键243，横轴241上设有装配孔，竖轴242的上端伸入到装配孔内且与装配孔过盈配合，竖轴242的上端的外周壁设有键槽，平键243设在键槽内且与装配孔的内周壁接触，平键243的长度与装配孔的长度相同。For example, the T-axis 240 includes a horizontal axis 241, a vertical axis 242, and a flat key 243.

下面结合图1至图10详细描述根据本公开实施例的单开关节可挠型道岔200的工作过程。The operation of the single-switch section flexible ballast 200 according to an embodiment of the present disclosure will be described in detail below with reference to FIGS. 1 through 10.

在初始位置，单开关节可挠型道岔200处于直线状态，导向挠曲板和稳定挠曲板为直线状态。当中央控制***发出挠曲变形指令后，驱动件22例如电动推杆(或液压缸)的活动推杆伸出，一方面经过中间连杆传动结构，带动道岔梁210内上下两个轴向圆柱凸轮组件顺时针转动，使得挠曲推杆(例如第一挠曲推杆113)推动导向挠曲板和稳定挠曲板产生近似圆弧的挠曲变形，另一方面经第二拉杆51和第三拉杆53，带动相邻道岔梁210内的挠曲推杆(例如第二挠曲推杆413)推动导向挠曲板和稳定挠曲板产生同向挠曲变形；当挠曲到位后，中央控制***发出位置保持指令，电动推杆的活动推杆在相应位置保持不动，即挠曲推杆在指定位置不动；当单轨列车通过后，中央控制***发出复位指令，电动推杆的活动推杆缩进，从而带动挠曲推杆回到初始位置，导向挠曲板和稳定挠曲板恢复到直线状态。至此完成根据本公开实施例的单开关节可挠型道岔200的工作过程。In the initial position, the single-switch section flexible track 200 is in a straight line state, and the guiding flexure plate and the stable flexure plate are in a straight state. When the central control system issues a deflection deformation command, the driving member 22, for example, the movable push rod of the electric push rod (or hydraulic cylinder) protrudes, and on the other hand, passes through the intermediate link transmission structure to drive the upper and lower axial cylinders in the ballast beam 210. The cam assembly rotates clockwise, so that the flexing push rod (for example, the first flexing push rod 113) pushes the guiding flexure plate and the stable flexing plate to generate an approximately circular arc deflection deformation, and on the other hand, the second pull rod 51 and the second The three pull rods 53 drive the flexing push rods (for example, the second flexing push rods 413) in the adjacent ballast beams 210 to push the guiding flexure plates and the stable flexure plates to produce the same deflection; when the deflection is in place, the center The control system issues a position hold command, and the movable push rod of the electric push rod remains stationary at the corresponding position, that is, the flexing push rod does not move at the designated position; when the monorail train passes, the central control system issues a reset command, the activity of the electric push rod The push rod is retracted, thereby driving the flexing push rod back to the initial position, and the guiding flexure plate and the stable flexing plate are restored to a straight state. The operation of the single-switch section flexible ballast 200 according to an embodiment of the present disclosure is thus completed.
