下面参考图1-图14描述根据本申请实施例的轨道梁100。Hereinafter, the track beam 100 according to the embodiment of the present application will be described with reference to FIGS. 1 to 14.
如图1-图14所示,根据本申请实施例的轨道梁100,包括:第一轨道梁1、第二轨道梁2和连接组件3。As shown in FIG. 1 to FIG. 14, the track beam 100 according to the embodiment of the present application includes: a first track beam 1, a second track beam 2 and a connecting component 3.
具体而言,第一轨道梁1的一端具有第一搭接部11,第二轨道梁2的一端具有第二搭接部21,第二搭接部21搭接在第一搭接部11的下方。连接组件3的上部与第一搭接部11相连,连接组件3的下部与第二搭接部21相连,以使第一搭接部11与第二搭接部21通过连接组件3相连。Specifically, one end of the first rail beam 1 has a first overlap portion 11, and one end of the second rail beam 2 has a second overlap portion 21, and the second overlap portion 21 is overlapped on the first overlap portion 11. Below. The upper part of the connecting assembly 3 is connected to the first overlapping part 11, and the lower part of the connecting assembly 3 is connected to the second overlapping part 21, so that the first overlapping part 11 and the second overlapping part 21 are connected through the connecting assembly 3.
由此可知,第一轨道梁1和第二轨道梁2的接缝处设有连接组件3以将第一轨道梁1和第二轨道梁2相连接。从而与现有技术相比,本申请实施例的轨道梁100可以仅在第一轨道梁1所在的一侧或者第二轨道梁2所在一侧设置支座以对轨道梁100进行支撑即可,未设置支座一侧的轨道梁100部分可通过连接组件3将受到的列车200的压力传递给另一侧轨道梁100部分。It can be seen from this that a connecting component 3 is provided at the joint of the first rail beam 1 and the second rail beam 2 to connect the first rail beam 1 and the second rail beam 2. Therefore, compared with the prior art, the track beam 100 of the embodiment of the present application can only be provided with a support on the side where the first track beam 1 is located or the side where the second track beam 2 is located to support the track beam 100. The part of the rail beam 100 on the side where the support is not provided can transmit the pressure of the train 200 to the part of the rail beam 100 on the other side through the connecting assembly 3.
已知,第二搭接部21搭接在第一搭接部11的下方,从而当连接组件3失效时,第二搭接部21可在一定程度上对第一搭接部11起到支撑作用,使第一搭接部11和第二搭接部21的配合形成二道防线以防止连接组件3失效后轨道梁100马上出现故障,提高轨道交通系统1000的安全可靠性。由此可以仅在第二轨道梁2所在的一侧设置支座,第一轨道梁1所在的一侧可不设置支座,则当列车200行驶至第一轨道梁1与第二轨道梁2的接缝处时,第一轨道梁1受到的压力可以通过连接组件3由上至下传递给第二轨道梁2,第二轨道梁2传递给支座。由此可以保证列车200在轨道梁100上行驶的可靠性。同时上述的设置方式有利于减少设置支座的数量,简化轨道梁100的制造工序,降低轨道梁100的制造成本。It is known that the second overlap portion 21 overlaps below the first overlap portion 11, so that when the connection assembly 3 fails, the second overlap portion 21 can support the first overlap portion 11 to a certain extent. In this way, the cooperation of the first overlap portion 11 and the second overlap portion 21 forms two lines of defense to prevent the rail beam 100 from failing immediately after the connection assembly 3 fails, and to improve the safety and reliability of the rail transit system 1000. Therefore, the support can be provided only on the side where the second track beam 2 is located, and the support is not required to be provided on the side where the first track beam 1 is located. When the train 200 travels to the first track beam 1 and the second track beam 2 At the joint, the pressure on the first rail beam 1 can be transferred to the second rail beam 2 through the connecting assembly 3 from top to bottom, and the second rail beam 2 is transferred to the support. Therefore, the reliability of the train 200 running on the track beam 100 can be ensured. At the same time, the above arrangement method is beneficial to reduce the number of supporting seats, simplify the manufacturing process of the track beam 100, and reduce the manufacturing cost of the track beam 100.
同时可知,第一轨道梁1受到的列车200的压力大部分方向是向下的,并且第一轨 道梁1是通过连接组件3将受到的向下的压力传递给第二轨道梁2的,然后第二轨道梁2传递给支座。已知,连接组件3的上部与第一搭接部11相连,连接组件3的下部与第二搭接部21相连。从而可知,在本申请实施例的轨道梁100中,力的传递过程为:列车200对第一轨道梁1施加压力,第一轨道梁1通过第一搭接部11可将向下方向的压力传递给连接组件3,连接组件3将力由上至下传递,然后传递给第二搭接部21,第二搭接部21将力传递给第二轨道梁2所在一侧设置的支座,由此可实现支座对第二轨道梁2和第一轨道梁1的支撑。At the same time, it can be seen that most of the direction of the pressure of the train 200 received by the first rail beam 1 is downward, and the first rail beam 1 transmits the downward pressure received to the second rail beam 2 through the connecting assembly 3, and then The second rail beam 2 is transferred to the support. It is known that the upper part of the connecting assembly 3 is connected to the first overlapping part 11, and the lower part of the connecting assembly 3 is connected to the second overlapping part 21. It can be seen that, in the track beam 100 of the embodiment of the present application, the force transmission process is: the train 200 applies pressure to the first track beam 1, and the first track beam 1 can transfer the downward pressure through the first lap 11 It is transmitted to the connecting assembly 3, the connecting assembly 3 transfers the force from top to bottom, and then to the second overlapping part 21, the second overlapping part 21 transfers the force to the support provided on the side where the second rail beam 2 is located, In this way, the support for the second rail beam 2 and the first rail beam 1 can be realized.

Of course, it should be noted that the first connecting member 4 may also be other structural members, as long as the reliability of the first connecting member 4 connecting the first rail beam 1 and the connecting assembly 3 is ensured.
在一实施例中,如图3、图4、图8和图9所示,连接组件3还包括:第一垫板32,第一垫板32为两个,每个连接板31与第一搭接部11之间分别垫设一个第一垫板32,第一垫板32安装在第一搭接部11或连接板31上,第一垫板32上具有第一过孔32a,第一过孔32a和第一连接孔11a、第一配合孔31a数量均相同且位置相对,第一连接件4穿设于第一连接孔11a、第一过孔32a和第一配合孔31a。从而可知,第一垫板32设置,可在一定程度上提高连接组件3与第一搭接部11的连接强度和可靠性,进而提高轨道梁100的可靠性。同时第一过孔32a的结构设置,使得第一垫板32的增设不会增大连接组件3与第一搭接部11连接装配过程的难度。可选地,第一垫板32焊接在对应的连接板31上。由此便于连接组件3的安装。In an embodiment, as shown in FIGS. 3, 4, 8 and 9, the connecting assembly 3 further includes: a first pad 32, the first pad 32 is two, and each connecting board 31 is connected to the first pad 32. A first backing plate 32 is provided between the overlapping parts 11 respectively. The first backing plate 32 is installed on the first overlapping part 11 or the connecting plate 31. The first backing plate 32 has a first through hole 32a. The via holes 32a, the first connecting holes 11a, and the first mating holes 31a have the same number and are opposite in position, and the first connecting member 4 penetrates the first connecting holes 11a, the first via holes 32a, and the first mating holes 31a. It can be seen that the provision of the first backing plate 32 can improve the connection strength and reliability of the connection assembly 3 and the first overlap portion 11 to a certain extent, thereby improving the reliability of the track beam 100. At the same time, the structure of the first via 32a is arranged so that the addition of the first backing plate 32 will not increase the difficulty of the connecting assembly 3 and the first overlapping portion 11 in the assembly process. Optionally, the first backing plate 32 is welded to the corresponding connecting plate 31. This facilitates the installation of the connection assembly 3.
如图5和图7所示,在本申请的一些实施例中,第二连接孔21a为滑移孔,第二连接件5为穿设于第二连接孔21a和第二配合孔31b的转动销轴5a,转动销轴5a沿第二连接孔21a的延伸方向可滑移。从而可知,第二连接件5为转动销轴5a的限定不但有利于保证连接组件3与第二搭接部21配合的可靠性,而且便于连接组件3的装配。同时可知,当转动销轴5a滑移时,或者第一轨道梁1受力时,连接板31可相对转动销轴5a发生转动,进而有利于第一轨道梁1释放轨道梁100在第一轨道梁1和第二轨道梁2 的接缝处的延伸方向上的弯矩,减小轨道梁100的变形,提高轨道梁100的可靠性。并且第一轨道梁1还可以通过转动销轴5a向第二轨道梁2传递Y向荷载(Y向指的是垂直与上下方向并且垂直于轨道梁100在第一轨道梁1和第二轨道梁2的接缝处的延伸方向),进而释放Y向的弯矩约束。其中转动销轴5a可以为开口销,但不限于此。As shown in FIGS. 5 and 7, in some embodiments of the present application, the second connecting hole 21a is a sliding hole, and the second connecting member 5 is a rotation hole that passes through the second connecting hole 21a and the second mating hole 31b. The pin shaft 5a and the rotating pin shaft 5a are slidable along the extending direction of the second connecting hole 21a. Therefore, it can be seen that the limitation of the second connecting member 5 as the rotation pin shaft 5 a is not only beneficial to ensure the reliability of the cooperation between the connecting assembly 3 and the second overlapping portion 21, but also facilitates the assembly of the connecting assembly 3. At the same time, it can be seen that when the rotating pin shaft 5a slips, or when the first track beam 1 receives a force, the connecting plate 31 can rotate relative to the rotating pin shaft 5a, which is beneficial for the first track beam 1 to release the track beam 100 on the first track. The bending moment in the extending direction of the joint between the beam 1 and the second rail beam 2 reduces the deformation of the rail beam 100 and improves the reliability of the rail beam 100. And the first rail beam 1 can also transmit Y-direction load to the second rail beam 2 by rotating the pin shaft 5a (Y-direction refers to the vertical and up-down direction and perpendicular to the rail beam 100 in the first rail beam 1 and the second rail beam 2), and then release the Y-direction bending moment constraint. The rotating pin shaft 5a may be a split pin, but it is not limited to this.
同时,由于转动销轴5a沿第二连接孔21a的延伸方向可滑移,从而可使连接组件3能够适应第一轨道梁1和第二轨道梁2在一定范围内的变形,提高连接组件3的可靠性,提高轨道梁100的可靠性。可选地,第二连接孔21a的延伸方向为轨道梁100在第一轨道梁1和第二轨道梁2的接缝处的延伸方向,从而可以使连接组件3在第一轨道梁1和第二轨道梁2发生热胀冷缩现象时发生滑动,提高连接组件3的可靠性,提高轨道梁100的可靠性。At the same time, because the rotating pin 5a can slide along the extension direction of the second connecting hole 21a, the connecting assembly 3 can be adapted to the deformation of the first rail beam 1 and the second rail beam 2 within a certain range, and the connecting assembly 3 can be improved. The reliability of the track beam 100 is improved. Optionally, the extension direction of the second connecting hole 21a is the extension direction of the rail beam 100 at the joint of the first rail beam 1 and the second rail beam 2, so that the connecting assembly 3 can be connected to the first rail beam 1 and the second rail beam. The second track beam 2 slides when it undergoes thermal expansion and contraction, which improves the reliability of the connecting assembly 3 and improves the reliability of the track beam 100.
在一实施例中,如图2、图6、图7和图10所示,连接组件3还包括:第二垫板33,第二垫板33为两个,每个连接板31与第二搭接部21之间分别垫设一个第二垫板33,第二垫板33安装在第二搭接部21上,第二垫板33上具有第二过孔33a,第二过孔33a与第二连接孔21a的形状相同且位置相对,第二连接件5穿设于第二连接孔21a、第二过孔33a和第二配合孔31b,且沿第二过孔33a和第二连接孔21a滑移。从而可知,第二垫板33设置,可在一定程度上提高连接组件3与第二搭接部21的连接强度和可靠性,进而提高轨道梁100的可靠性。同时第二过孔33a的结构设置,使得第二垫板33的增设不会增大连接组件3与第二搭接部21连接装配过程的难度。可选地,第二垫板33焊接在第二轨道梁2的腹板23上。由此便于连接组件3的安装,使第二垫板33安装在第二搭接部21上的方式简单、可靠。In an embodiment, as shown in Figures 2, 6, 7, and 10, the connecting assembly 3 further includes: a second pad 33, the second pad 33 is two, each connecting plate 31 and the second A second backing plate 33 is provided between the overlapping parts 21, and the second backing plate 33 is installed on the second overlapping part 21. The second backing plate 33 has a second through hole 33a, and the second through hole 33a is connected to the The second connecting holes 21a have the same shape and opposite positions. The second connecting member 5 penetrates the second connecting hole 21a, the second via 33a, and the second mating hole 31b, and runs along the second via 33a and the second connecting hole. 21a slippage. Therefore, it can be seen that the provision of the second backing plate 33 can improve the connection strength and reliability of the connection assembly 3 and the second overlap portion 21 to a certain extent, thereby improving the reliability of the track beam 100. At the same time, the structure of the second via 33a is arranged so that the addition of the second backing plate 33 will not increase the difficulty of the connection assembly process of the connecting assembly 3 and the second lap 21. Optionally, the second backing plate 33 is welded to the web 23 of the second rail beam 2. This facilitates the installation of the connecting assembly 3, and makes the way of installing the second backing plate 33 on the second overlapping portion 21 simple and reliable.
在一实施例中,如图7和图11所示,连接组件3还包括:第一包裹件34,第一包裹件34至少包裹第二连接孔21a的滑移配合面211。从而在转动销轴5a在第二连接孔21a内滑移时,第一包裹件34的设置可以有效地避免转动销轴5a与第二连接孔21a的滑移配合面211接触,进而可在一定程度上减小转动销轴5a在第二连接孔21a内滑移时产生的摩擦力。可选地,第一包裹件34可以为两个且分别用于包裹第二连接孔21a的上下两个相对的滑移配合面211。In an embodiment, as shown in FIGS. 7 and 11, the connecting assembly 3 further includes: a first wrapping member 34 that at least wraps the sliding mating surface 211 of the second connecting hole 21 a. Therefore, when the rotating pin 5a slides in the second connecting hole 21a, the arrangement of the first wrapping member 34 can effectively prevent the rotating pin 5a from contacting the sliding mating surface 211 of the second connecting hole 21a, and thus can be fixed at a certain distance. To a certain extent, the frictional force generated when the rotating pin 5a slips in the second connecting hole 21a is reduced. Optionally, there may be two first wrapping members 34 and they are used to respectively wrap the upper and lower sliding mating surfaces 211 of the second connecting hole 21a.
例如在图11所示的具体示例中,第一包裹件34可以为不锈钢套,由于不锈钢材料表面较光滑平整,从而有利于减小转动销轴5a在第二连接孔21a内滑移时产生的摩擦力。此外,如图11所示,作为第一包裹件34的不锈钢套可以大体形成为U形。由此使得不锈钢套的结构简单,便于不锈钢套包裹第二连接孔21a的滑移配合面211。For example, in the specific example shown in FIG. 11, the first wrapping member 34 may be a stainless steel sleeve. Since the surface of the stainless steel material is relatively smooth and flat, it is beneficial to reduce the occurrence of slippage of the rotating pin 5a in the second connecting hole 21a. Friction. In addition, as shown in FIG. 11, the stainless steel sleeve as the first wrapping member 34 may be formed substantially in a U shape. Therefore, the structure of the stainless steel sleeve is simple, and it is convenient for the stainless steel sleeve to wrap the sliding mating surface 211 of the second connecting hole 21a.
结合图7,U形不锈钢套的闭口端可以包裹在第二连接孔21a的滑移配合面211上, U形不锈钢套的相对两侧壁可以分别夹设在第二垫板33的两侧,且这两侧壁的远离第二连接孔21a的一端分别朝向彼此靠近的方向弯折、以夹扣在第二垫板33的外边沿上。由此,可在一定程度上减小转动销轴5a在第二连接孔21a内滑移时产生的摩擦力,同时便于第一包裹件34的安装和拆卸。With reference to Fig. 7, the closed end of the U-shaped stainless steel sleeve can be wrapped on the sliding mating surface 211 of the second connecting hole 21a, and the opposite side walls of the U-shaped stainless steel sleeve can be sandwiched on both sides of the second backing plate 33, respectively. And the ends of the two side walls away from the second connecting hole 21a are respectively bent toward the direction of approaching each other so as to be clamped on the outer edge of the second backing plate 33. As a result, the frictional force generated when the rotating pin 5a slides in the second connecting hole 21a can be reduced to a certain extent, and at the same time, the installation and removal of the first wrapping member 34 can be facilitated.
如图2、图6、图12和图13所示,在本申请的一些实施例中,连接组件3还包括:滑块35,滑块35套设在第二连接件5外且穿设于第二连接孔21a,以沿第二连接孔21a滑移。从而可知,滑块35可以与第二连接件5(例如上文所述的转动销轴5a)同时沿着第二连接孔21a滑移。同时,由于滑块35套设在第二连接件5外,从而有利于固定转动销轴5a在轴向上的位置。提高连接组件3的可靠性。As shown in Figure 2, Figure 6, Figure 12 and Figure 13, in some embodiments of the present application, the connecting assembly 3 further includes: a slider 35, the slider 35 is sleeved outside the second connecting member 5 and penetrates through The second connecting hole 21a is to slide along the second connecting hole 21a. Therefore, it can be seen that the slider 35 can slide along the second connecting hole 21a at the same time as the second connecting member 5 (for example, the rotating pin shaft 5a mentioned above). At the same time, since the slider 35 is sleeved outside the second connecting member 5, it is advantageous to fix the position of the rotating pin shaft 5a in the axial direction.
