Description

悬挂式轨道变轨系统Suspended track change system 技术领域Technical field
本发明涉及交通技术领域,尤其是涉及一种悬挂式轨道变轨系统。The invention relates to the technical field of transportation, and in particular to a suspended track changing system.
背景技术Background technique
随着城市化进程加快,越来越多的资源及劳动力涌向城市,促进城市发展同时,交通拥堵问题越来越突出,尤其是一些大城市的交通状况更为严重,交通拥堵已严重影响到城市的发展。With the acceleration of the urbanization process, more and more resources and labor force have flowed to cities, and at the same time, the problem of traffic congestion has become increasingly prominent, especially in some large cities. Urban development.
常规道路交通,已经占用了地面,虽然高架桥能充分利用城市的近地面空间,但高架桥造价高,噪音大,占地大,也不可能大面积建设。地铁轨道交通系统充分利用地下空间,运力大,为目前大型城市缓解交通拥堵的有效手段,但地铁建设成本高,难度大,建设周期长,不能从根本上解决城市交通拥堵。Conventional road traffic has already occupied the ground. Although the viaduct can make full use of the city's near-surface space, the viaduct is costly, noise, and occupies a large area. The subway rail transportation system makes full use of underground space and has a large transportation capacity, which is an effective means to alleviate traffic congestion in large cities at present, but the construction cost of the subway is high, the difficulty is long, and the construction period is long.
传统的轨道交通系统在运行过程中需要改变运行轨道时,需要通过轨道道岔的机械运动来调整轨道的状态来切换机车的运行轨道,不但轨道的施工时间长,而且该方案存在一个弊端,就是非固定道岔变轨需要较长时间来完成操作,基于安全的原则必然会预留足够的变轨安全时间,这必然拉大轨道上运行的前后车的安全距离,严重拉低了轨道交通的运力,降低运行平均速度,浪费乘客通行时间。当轨道上运行的是大运力的火车编组时,这个弊端体现不明显,但当轨道运用于PRT(Personal Rapid Transit个人快速运输系统)时,该弊端立刻明显放大。特别是高速运行的PRT轨道交通,假设机车变轨需要10秒的安全变轨时间,则当机车运行速度为80公里/小时时,前后车需要安全间距为222米,这样的安全距离使整个轨道交通系统的运行效率很低。When the traditional rail transit system needs to change the running track during the operation, it is necessary to adjust the state of the track to switch the running track of the locomotive through the mechanical movement of the track turnout. Not only the track construction time is long, but there is a disadvantage of this solution. Fixed turnout changes take a long time to complete the operation. Based on the principle of safety, sufficient safety time will be reserved for the changeover. This will inevitably increase the safety distance of the front and rear vehicles running on the track, which will seriously reduce the capacity of the rail transit. Reduce the average running speed and waste passenger transit time. This disadvantage is not obvious when a train of high capacity is running on the track, but when the track is used in a Personal Rapid Transit (PRT) system, the disadvantage is immediately amplified. Especially for high-speed PRT rail transit, assuming that the locomotive needs 10 seconds to change safety, when the locomotive runs at 80 km / h, the safety distance between the front and rear vehicles needs to be 222 meters. This safety distance makes the entire track The operating efficiency of the transportation system is very low.

The two walking mechanisms are located in the vehicle body 11 and are divided on both sides of the dual axis motor 14. A cam 15 is provided on each of the two shafts of the two-axis motor 14, and the two cams 15 are oppositely disposed. Because the two cams are oppositely disposed, as the motor rotates, the movement trajectories of the two cams are opposite, and because they are cams, According to the characteristics of the cam, during the rotation of the two cams, there must be a position when one cam lifts the lifting member, and the other cam can cause the lifting member to fall.
每个行走机构均包括两组相对设置的行走组件,每组行走组件均包括升降件19、一个上行走轮12、一个下行走轮13和两个曲柄16,两曲柄16之间的上端连接升降件19,下端连接下行走轮13、中间折弯部连接上行走轮12;双轴电机14两侧的升降件19的下端分别与该侧对应的凸轮15上端接触。Each walking mechanism includes two oppositely-arranged walking components, each of which includes a lifting member 19, an upper walking wheel 12, a lower walking wheel 13, and two cranks 16, and the upper ends of the two cranks 16 are connected to lift The lower end is connected to the lower traveling wheel 13 and the middle bending part is connected to the upper traveling wheel 12; the lower ends of the lifting members 19 on the two sides of the biaxial motor 14 are in contact with the upper ends of the cams 15 corresponding to this side, respectively.

本发明悬挂式轨道变轨系统,在同一行走组件中的两曲柄16之间还横穿一限位轴17,限位轴17同时穿过相邻行走组件中的两曲柄,限位轴17横穿的位置位于上、下行走轮之间,且限位轴17的两端分别与车体11的两侧内壁连接。此时以限位轴作为支点,在传动轮升降的过程中,上、下行走轮能够被伸开或收缩,在上、下行走轮伸开时,行走机构可用于行走。According to the suspension track changing system of the present invention, a limit shaft 17 is also traversed between two cranks 16 in the same traveling component, and the limit shaft 17 passes through both cranks in adjacent traveling components at the same time. The wearing positions are located between the upper and lower traveling wheels, and both ends of the limiting shaft 17 are respectively connected to the inner walls of both sides of the vehicle body 11. At this time, the limit axis is used as a fulcrum. During the lifting of the transmission wheel, the upper and lower walking wheels can be extended or contracted. When the upper and lower walking wheels are extended, the walking mechanism can be used for walking.
本发明悬挂式轨道变轨系统,所述凸轮15包括连续的圆弧形曲面18和曲槽,圆弧形曲面18以双轴电机14的轴为圆心,且在该圆弧形曲面18与升降件19接触时,升降件19被升至最高位,曲槽与升降件19接触时,升降件19降至最低位;According to the suspension track changing system of the present invention, the cam 15 includes a continuous arc-shaped curved surface 18 and a curved groove. The arc-shaped curved surface 18 is centered on the axis of the biaxial motor 14, and the arc-shaped curved surface 18 is lifted and lowered. When the member 19 contacts, the lifting member 19 is raised to the highest position, and when the curved groove contacts the lifting member 19, the lifting member 19 is lowered to the lowest position;
在本悬挂式轨道变轨系统中,变轨前后,两行走机构中的行走轮均可同时伸出,只需在变轨过程中将不需要的一侧行走轮收起即可。而为了节省能耗以及提高行走轮的使用寿命,在变轨前后一般只采用一侧行走机构行走。即,In the suspension track changing system, the running wheels in the two running mechanisms can be extended simultaneously before and after the changing, and only the unwanted side wheels need to be stowed during the changing process. In order to save energy consumption and improve the service life of walking wheels, generally only one side of the walking mechanism is used before and after the derailment. which is,
变轨前,与两第一基础轨一侧的行走机构中的凸轮圆弧形曲面在上端,传动轮位于最高位,在限位轴和曲柄的作用下,上、下行走轮伸开并在第一基础轨上行走;另一侧的行走机构中凸轮的曲槽在上端,传动轮位于下凹的曲槽中,为最低位,在限位轴和曲柄的作用下,上、下行走轮收缩,不与第二基础轨接触,此时机车在第一基础轨上行走。Before the orbital change, the cam circular arc surface in the traveling mechanism on the side of the two first base rails is at the upper end, and the transmission wheel is at the highest position. Under the action of the limit shaft and the crank, the upper and lower traveling wheels are extended and The first basic track travels; the cam groove in the running mechanism on the other side is at the upper end, and the transmission wheel is located in the concave curved groove at the lowest position. Under the action of the limit shaft and the crank, the upper and lower walking wheels Shrink without contacting the second base rail, at this time the locomotive is walking on the first base rail.
变轨过程中,两凸轮的圆弧形曲面均在上端时,两侧的传动轮均位于最高位,此时在限位轴和曲柄的作用下,两侧所有的行走轮都伸开并在对应的轨道上行走,当机车需要脱离第一基础轨时,与第一基础轨一侧的行走机构中凸轮的曲槽转至上端,该侧的行走轮收起并脱离第一基础轨。During the derailment process, when the arc surfaces of the two cams are at the upper end, the transmission wheels on both sides are at the highest position. At this time, under the action of the limit shaft and the crank, all the walking wheels on both sides are extended and When the locomotive needs to disengage from the first base rail, when the locomotive needs to be disengaged from the first base rail, the curved groove of the cam in the running mechanism on the side of the first base rail is turned to the upper end, and the traveling wheel on the side is retracted and separated from the first base rail.
变轨后,与第二基础轨一侧的行走机构中的凸轮圆弧形曲面在上端,传动轮位于最高位,上、下行走轮沿着第一基础轨继续在第二基础轨上行走;另一侧的行走机构中的凸轮曲槽在上端,传动轮位于最低位,上、下行走轮不与第一基础轨接触。After the orbital change, the cam curved surface in the running mechanism on the side of the second base rail is at the upper end, the transmission wheel is at the highest position, and the upper and lower walking wheels continue to walk on the second base rail along the first base rail; The cam curved groove in the running mechanism on the other side is at the upper end, the transmission wheel is at the lowest position, and the upper and lower traveling wheels do not contact the first base rail.

本发明悬挂式轨道变轨系统,引导轨4的前端两侧均由外向内收缩,因此该前端的宽度小于引导轨本身的宽度,因此机车的行走轮在与其接触的瞬间避免与引导轨碰撞,使机车变轨顺畅。In the suspension rail changing system of the present invention, both sides of the front end of the guide rail 4 are contracted from the outside to the inside, so the width of the front end is smaller than the width of the guide rail itself, so the traveling wheels of the locomotive avoid collision with the guide rail at the moment of contact with it.

本发明的有益效果是:The beneficial effects of the present invention are:
本发明结构简单,易施工且成本低,在机车需要变轨时也无需调整轨道状态,不存在道岔的机械运动以及结构的变化,仅仅只通过机车行走轮状态的改变再配合轨道整体的结构,使得机车可快速变轨,可以前车紧跟后车,根据需要,前后车只需要预留数米的安全距离即可,从而从根本上解决了轨道交通的变轨问题。The invention has simple structure, easy construction, and low cost. When the locomotive needs to change rails, there is no need to adjust the track state. There are no mechanical movements and structural changes of the turnout. The locomotive can quickly change rails, and the front car can closely follow the rear car. According to the needs, the front and rear cars only need to reserve a safety distance of several meters, thereby fundamentally solving the problem of rail transit derailment.
