The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention and are not to be construed as limiting the present invention.
A connecting device 100 for connecting conductive rails according to an embodiment of the present invention is described below with reference to fig. 1 to 23.
The connecting device 100 for connecting a conductor rail according to an embodiment of the present invention can be used for the connection of a conductor rail of an articulated switch, laying conductor rails on the sides of the rail beams, the rail beams can be used for bearing and transmitting the gravity, the guiding force, the traction force and the braking force of the train, the conductor rails can be matched with collector shoes on the rail vehicle to transmit electric power to the rail vehicle, the connecting device 100 for connecting conductor rails can be used to connect two conductor rails, front and rear, i.e. forward and backward directions of a rail vehicle, in some embodiments, the conductor rail may be provided on a side of the rail beam, with the conductive surface of the conductor rail facing laterally outward of the rail beam to facilitate mating with the collector shoe, the X direction, i.e. the longitudinal direction, is the length direction of the conductive rail, the Y direction, i.e. the transverse direction, is the width direction of the conductive rail, and the Z direction, i.e. the vertical direction, is the height direction of the conductive rail.
The connecting device 100 for connecting a conductor rail according to the embodiment of the present invention can be used for connecting a conductor rail of a straddle type rail beam, as described above, in the rail transit provided by the present invention, the rail vehicle straddles on the rail beam, and it can be understood that the "straddling" is to define the rail vehicle, i.e., the vehicle body of the rail vehicle rides on the rail beam, and the relative position of the horizontal wheel in the bogie and the rail beam is not particularly limited. For example, the horizontal wheels may be freely fitted to the outer or inner side walls of the track beam to accommodate different sized track beam structures. In other words, in the rail transit system provided by the invention, the rail vehicle straddles on the rail beam, namely, the rail beam structure is wrapped by the vehicle body, and the width dimension of the vehicle body is larger than that of the rail beam.
As shown in fig. 1 to 23, a connecting device 100 for connecting conductive rails according to an embodiment of the present invention includes: the connecting joint assembly 1, the transition plate 2 and the flexible connecting piece 3.
The connector assembly 1 comprises a base 11 and a sliding table 12, the base 11 and the sliding table 12 can slide relatively along a first direction, two connector assemblies 1 form a group, the two connector assemblies 1 in each group are distributed in a mirror symmetry manner, that is, the two connecting terminal assemblies 1 in each group are symmetrically distributed by taking the plane between the opposite end faces of the front conductive rail 200 and the rear conductive rail 300 as a symmetry plane, one base 11 of the connecting terminal assembly 1 in each group is used for connecting with the front conductive rail 200, the other base 11 of the connecting terminal assembly 1 in each group is used for connecting with the rear conductive rail 300, wherein the first direction can be divided into vertical direction and longitudinal direction, the relative sliding of the base 11 and the sliding table 12 in the first direction is used for compensating the change of the relative position of the front conductive rail 200 and the rear conductive rail 300 when the turnout beam is switched, therefore, the connecting device 100 can still realize the power supply of the collector shoe when the turnout beam is switched.
The transition plate 2 is connected to two sliding tables 12 of each set of the connector assemblies 1, that is, the sliding table 12 corresponding to the base 11 connected to the front conductive rail 200 is connected to the sliding table 12 corresponding to the base 11 connected to the rear conductive rail 300, and the lateral outer side surface of the transition plate 2 forms a smooth transition with the lateral outer side surface of the front conductive rail 200 and the lateral outer side surface of the rear conductive rail 300, for example, the three surfaces may be flush, which is convenient for the collector shoe to pass through. When the switch beam is switched, when the sliding table 12 moves relative to the base 11, the transition plate 2 moves along with the sliding table 12, so that a gap generated during the switch beam switching is eliminated, and a collector shoe can be connected at the transition position of the front conductor rail 200 and the rear conductor rail 300 through the transition plate 2.
The transition plate 2 is used for matching with a collector shoe, so that the power supply of the collector shoe by the connecting device 100 is realized, and when the collector shoe is matched with the transition plate 2, the collector shoe can obtain electric energy from the transition plate 2. The flexible connector 3 is used for connecting the front conductive rail 200 and the rear conductive rail 300 to serve as the electrical connection of the conductive rails at two ends, in some examples, the flexible connector 3 can connect the front conductive rail and the rear conductive rail through bolts, and the bolt connection mode is adopted, so that the assembly is simple and the connection effect is good.
The collector shoe of the railway vehicle can be matched with the transition plate 2, namely the collector shoe can be electrically connected with the transition plate 2 at the joint of the front guide rail and the rear guide rail, so that the railway vehicle can obtain electric power from the transition plate 2 at the point of a turnout when running, the situation of instantaneous power loss can not occur, electric arcs generated when the collector shoe is separated from a conductor rail can be prevented, the collector shoe can also be prevented from being impacted at the joint of the front guide rail and the rear guide rail, and the function of protecting the collector shoe is further achieved.
Therefore, the flexible connecting piece 3 can be connected with the inner side surfaces of the front conductive rail 200 and the rear conductive rail 300 to further complete the electrical connection of the front conductive rail 200 and the rear conductive rail 300, the transition plate 2 arranged on the connecting joint assembly 1 opposite to the flexible connecting surface faces outwards, so that the transition plate 2 can be matched with the collector shoe, and the flexible connecting piece 3 of the transition plate 2 is connected with the sliding table 12 because the base 11 and the sliding table 12 can move relatively, the sliding table 12 at the front guide rail and the sliding table 12 at the rear guide rail can move relatively, and because the transition plate 2 is connected with a plurality of (for example, two) sliding tables 12, and the plurality of (for example, two) sliding tables 12 are respectively connected with the front guide rail and the rear guide rail, when a switch is switched, the front and rear switch beams rotate relatively around the connecting axis to drive the insulators fixed on the switch beams to rotate relatively, thereby driving the conductive rails at two ends mounted on the insulators to rotate relatively, and further causing the elastic bending of the transition plate 2 to drive the sliding tables 12 to ascend or descend along the inclined plane of the conductive rail process. The sliding platform 12 can move relative to the corresponding base 11 in a self-adaptive manner, so that the transition plate 2 bends along with the switching of the turnout beam to form a section of continuous and smooth flexible line-type transition surface, so that the collector shoe can pass through the turnout continuously and smoothly, and the collector shoe cannot generate impact, instantaneous power loss and electric arc when passing through the transition plate 2. And the sliding table 12 cannot generate a gap in the ascending or descending process, so that the stable transition of the current collector is ensured, the running speed of a train is improved, and the noise is reduced.
In some examples, as shown in fig. 12 to 15, the sliding table 12 may further be provided with a transition plate installation groove 122, the transition plate 2 may be installed in the transition plate installation groove 122, and the depth of the transition plate installation groove 122 may be the same as the thickness of the transition plate 2, so that the process surfaces of the conductive rail on the connection device 100, the sliding table 12 and the transition plate 2 are on the same plane, so that the connection position of the transition plate 2 and the sliding table 12 is smoother.
In some examples, as shown in fig. 16, the transition plate 2 may be a stainless steel plate, the transition plate 2 may be provided with a plurality of countersunk holes 21, the sliding table 12 may be connected to the transition plate 2 by screws, that is, heads of the plurality of screws extend into the plurality of countersunk holes 21, and the screws are fastened to the sliding table 12 through the countersunk holes 21, the design of the countersunk holes 21 may make an outer surface of the transition plate 2 smoother, that is, the connection between the sliding table 12 and the transition plate 2 is achieved, and the smoothness of the surface of the transition plate 2 is also ensured, so as to facilitate the collector shoe to pass through the transition plate 2, and the thickness of the transition plate 2 may be determined according to the speed of the train passing through the switch beam and the pressure between the collector shoe and the conductor rail. In some embodiments, the thickness of the transition plate 2 is not more than 8mm so that the transition plate 2 can be elastically bent, the width of the transition plate 2 can reach 92mm, when a straddle type monorail travelling wheel is punctured, the integral sinking amount of a vehicle body is not more than 25mm, and the collector shoe can still be completely positioned on the surface of the transition plate 2 due to the large width of the transition plate 2, so that the accident that the collector shoe is separated from a conductor rail cannot be caused.
One surface of the flexible connecting piece 3 of the connecting device 100 for connecting the conductor rail can be connected with the side surface of the conductor rail, and the transition plate 2 which is arranged opposite to the flexible connecting piece is arranged towards the outer side of the conductor rail, so that a collector shoe of a railway vehicle can be brushed on the transition plate 2 to obtain electric energy, and the base 11 and the sliding table 12 can slide relatively in the longitudinal direction and the vertical direction, so that when a switch beam is switched, the connecting device 100 can compensate according to the change of the relative position of the front conductor rail 200 and the rear conductor rail 300 in the vertical direction and the longitudinal direction.
According to the connecting device 100 for connecting the conductor rail, provided by the connecting joint assembly 1, the transition plate 2 and the flexible connecting piece 3, when the switch is switched, the collector shoe can continuously and smoothly pass through the switch, and when the collector shoe passes through the connecting device 100, impact, instant power loss and electric arc cannot be generated, so that the function of protecting the collector shoe can be achieved.
Some embodiments of a connecting device 100 for connecting conductive rails according to embodiments of the invention are described below with reference to fig. 1-23.
In some embodiments, as shown in fig. 1-23, the connection joint assembly 1 further comprises: the sliding block 13, the sliding block 13 and the base 11 are in sliding fit, and the sliding table 12 slides relative to the base 11 through the sliding block 13. Thus, through the design of the sliding block 13, the degree of freedom of the connecting joint assembly 1 is higher, so that the structure at the position can be more flexible, and the change of the front conductive rail 200 and the rear conductive rail 300 can be adapted more quickly when the turnout is switched, and the performance of the connecting device 100 is improved.
In some embodiments, as shown in fig. 2 and 20, the sliding block 13 is slidably engaged with the base 11 in the second direction, the sliding table 12 is slidably engaged with the sliding block 13 in the third direction, and the second direction and the third direction are configured to be combined into the first direction, so that the sliding of the sliding table 12 relative to the base in the first direction is realized.
In some embodiments, as shown in fig. 2 and 20, the second direction is vertical, and the third direction can be decomposed into vertical direction and longitudinal direction, so that the relative sliding between the sliding block 13 and the base 11 in the vertical direction can be used to compensate the gap between the front guide rail 200 and the rear guide rail 300 in height when the switch is switched, and the relative sliding between the sliding block 13 and the sliding table 12 in the longitudinal direction and vertical direction can be used to compensate the gap between the front guide rail and the rear guide rail in longitudinal direction and vertical direction when the switch is switched, so that the connection device 100 can ensure that the collector shoe can smoothly pass through the gap, and because the second direction is vertical, when the connection device 100 is used to connect the front guide rail 200 and the rear guide rail 300, the error that the front guide rail 200 and the rear guide rail 300 are not consistent in height can be compensated by moving the sliding block 13 relative to the base in the vertical direction.
In some embodiments, as shown in fig. 1-23, the second direction and the third direction include an angle α, which satisfies: alpha is more than 0 degree and less than 90 degrees.
In some embodiments, as shown in fig. 1-23, the second direction and the third direction include an angle α, which satisfies: 15 DEG-alpha-60 DEG, for example, the slide 13 can be moved in a transverse direction relative to the base 11, the angle between the second direction and the third direction being 20 DEG or 50 deg.
In some embodiments, the second direction and the third direction include an angle α, satisfying: 30 DEG-alpha-45 DEG, for example, the slide 13 can be moved in a transverse direction relative to the base 11, the angle between the second direction and the third direction being 35 deg.
When the included angle alpha between the second direction and the third direction meets the conditions, the process inclined plane of the sliding table 12 and the process inclined plane of the conductor rail are always attached when the transition plate 2 is bent due to the point switch of the turnout beam, so that the gapless transition of the carbon sliding plate of the current collector is realized.
In some embodiments, as shown in fig. 1 to 23, the sliding block 13 is slidably engaged with the base 11 in a second direction, and the sliding table 12 is slidably engaged with the sliding block 13 in a third direction, where the second direction is vertical and the third direction is longitudinal, when the switch beam switches, a relative distance between the sliding block 13 and the conductive rail increases or decreases, so that a gap G needs to be reserved between the sliding block 13 and the conductive rail to compensate for a change in the relative distance between the conductive rail and the sliding block 13. In the transition connection, because a gap exists between the conductor rail and the sliding table 12, the speed of the carbon sliding plate of the current collector cannot be too high when the carbon sliding plate passes through the gap, and the carbon sliding plate is mainly suitable for occasions with low speed when trains pass through turnouts, such as a vehicle section or an auxiliary line.
In some embodiments, as shown in fig. 5 to fig. 15, a side of the base 11 facing away from the track beam is provided with a base sliding groove 111 extending along the second direction, a side of the slider 13 facing the base 11 is provided with a slider guide rail 131 in sliding fit with the base sliding groove 111, a side of the slider 13 facing away from the base 11 is provided with a slider sliding groove 132 extending along the third direction, and a side of the sliding table 12 facing the slider 13 is provided with a sliding table guide rail 121 in sliding fit with the slider sliding groove 132, so that guiding effect by matching of the sliding groove and the slider 13, and matching of the sliding groove and the sliding table 12 is good, positioning is accurate, and sliding efficiency is high, thereby improving reliability and stability of the structure at this position.
In some embodiments, as shown in fig. 5-15, the base sliding groove 111, the sliding block guide rail 131, the sliding block sliding groove 132, and the sliding block guide rail 121 are all wedge-shaped, so that the wedge-shaped engagement can function as a limit,
the wedge-shaped base sliding groove 111 limits five degrees of freedom of the slider guide rail 131, only the degree of freedom of the slider guide rail 131 moving along the axis of the base sliding groove 111 is reserved, the five degrees of freedom are used for compensating the error of the upper and lower heights of the front and rear sections of turnout beams, and the matching mode of the base sliding groove 111 and the slider guide rail 131 can also prevent the slider guide rail 131 from being separated from the base sliding groove 111 in the transverse direction.
Five degrees of freedom of the sliding table guide rail 121 are limited by the wedge-shaped sliding block sliding groove 132, and only the degree of freedom of movement of the sliding table guide rail 121 along the axis of the sliding block sliding groove 132 is reserved, so that when the turnout beam switch causes bending of the transition plate 2, the process inclined plane of the sliding table 12 and the process inclined plane of the conductor rail are always attached, no-gap transition of the current collector carbon sliding plate is achieved, and the sliding block sliding groove 132 and the sliding table guide rail 121 can be matched in a mode that the sliding table guide rail 121 can be prevented from being separated from the sliding block sliding groove 132 in the transverse direction.
In some embodiments, as shown in fig. 2 and 4, the connection joint assembly 1 may further include a limiting block 5, and the limiting block 5 may be mounted on the base 11 and fastened by a screw, and is used for limiting the displacement of the sliding table 12 along the axial direction of the conductive rail, and preventing the sliding table 12 from moving longitudinally to escape from the sliding block sliding groove 132.
In some embodiments, as shown in fig. 1 to 23, normal lines of end surfaces of the two sliding tables 12 of each group facing away from each other are perpendicular to the third direction, in other words, end surfaces of the two sliding tables 12 of each group facing away from each other are parallel to the third direction, and the end surfaces of the two sliding tables 12 of each group facing away from each other are respectively used for pressing the end surfaces of the front conductive rail 200 and the rear conductive rail 300 facing each other, so that a gap at a connection between the two sliding tables 12 and the front conductive rail 200 or the rear conductive rail 300 does not change along with movement of the sliding tables 12.
In some embodiments, as shown in fig. 1 to 23, normal lines of end surfaces of the two sliders 13 of each set facing away from each other are perpendicular to the third direction, in other words, the end surfaces of the two sliders 13 of each set facing away from each other are parallel to the third direction, and the end surfaces of the two sliders 13 of each set facing away from each other are respectively used for pressing the end surfaces of the front conductive rail 200 and the rear conductive rail 300 facing each other, so that a gap at a connection between the two sliders 13 and the front conductive rail 200 or the rear conductive rail 300 does not change with the movement of the sliding table 12.
