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 transition connection device 100 for a conductor rail 200 according to an embodiment of the present invention is described below with reference to fig. 1 to 20.

As shown in fig. 1 to 3, a transition connection device 100 for a conductor rail 200 according to an embodiment of the present invention includes: first contact rail section 1, the fixing base 2, two slip tables 3 and the transition subassembly 4 that two intervals set up.

Wherein, two fixing bases 2 one-to-one establish on two first contact rail section 1's the tip each other of orientation, every fixing base 2 can be fixed to the first contact rail section 1 of corresponding side, and two slip tables 3 are established on two fixing bases 2 respectively one-to-one and slidable. Specifically, as shown in fig. 2, both the first contact rail sections 1 may extend in the front-rear direction (the running direction of the railway vehicle), and the transition member 4 is provided between the two first contact rail sections 1. One of the holders 2 is arranged on the front side of the first contact rail section 1 located behind, and the other holder 2 is arranged on the rear side of the first contact rail section 1 located in front. The left side of every fixing base 2 all can be equipped with rather than sliding fit's slip table 3, and slip table 3 can reciprocate relatively corresponding fixing base 2. Therefore, the sliding table 3 can compensate the height deviation of the two first contact rail sections 1 during installation by sliding up and down relative to the fixed seat 2, so that the transition connection device 100 has a smooth transition effect.

As shown in fig. 1 and 4, two ends of the transition assembly 4 may be respectively slidably fitted with the two sliding tables 3 to adjust a gap 100a between the transition assembly 4 and the first contact rail section 1, at least a portion of the transition assembly 4 located between the two sliding tables 3 may be bent, and a sliding direction of the two sliding tables 3 and a sliding direction of the transition assembly 4 may have an included angle. Specifically, the transition assembly 4 can extend in the front-rear direction, the front end and the rear end of the transition assembly 4 are respectively in sliding fit with the corresponding sliding tables 3, and the transition assembly 4 can slide back and forth relative to the two sliding tables 3.

As shown in fig. 4, a gap 100a may be reserved between the transition assembly 4 and the two first contact rail segments 1. When the rail car vehicle is running, the gap 100a can define the sliding space of the transition assembly 4, so that the distance change between the front and rear sliding platforms 3 caused by the thermal expansion and contraction of the turnout switch or the conductor rail 200 can be compensated, and the conductor rail 200 can be smoothly switched.

Wherein the portion of the transition assembly 4 between the two ramp 3 can be curved. Consequently, two adjacent first contact rail sections 1 need not to buckle when the switch is switched on at the switch, only need transition subassembly 4 to bend and just can realize the steady switch of switch, can reduce the impact that conductor rail 200 and collector shoe received when the switch from this, can also reduce the frictional wear of the carbon slide on the collector shoe, not only can prolong the life of conductor rail 200 and collector shoe, can also promote rail vehicle's the stability of receiving power and rail vehicle's the security of traveling. It is understood that the transition member 4 may be configured to be flexible as a whole, and the configuration may be selected according to the actual use requirement.

Because the slip direction of two slip tables 3 and the slip direction of transition subassembly 4 have the contained angle, slip table 3 and transition subassembly 4 can slide towards different directions, can control the slip direction of slip table 3 and the slip direction of transition subassembly 4 respectively from this, can make the combined motion direction of slip table 3 and transition subassembly 4 the same with the goat's direction of switch, can make the collecting shoe can pass through clearance 100a between first contact rail section 1 and the slip table 3 smoothly from this, thereby can promote the cooperation stability between collecting shoe and the conductor rail 200, and then can promote rail vehicle's operation stationarity.

According to the transition connection device 100 for the conductor rail 200 provided by the embodiment of the invention, by arranging the sliding table 3, the sliding table 3 can slide up and down relative to the fixed seat 2 to compensate for the height deviation of the two first contact rail sections 1 during installation, so that the effect of smooth transition can be realized. The part flexible that is located between two slip tables 3 through setting up transition subassembly 4 can realize the smooth transition between two first contact rail sections 1, can reduce the impact that conductor rail 200 and collector shoe received when switching, not only can prolong the life of conductor rail 200 and collector shoe, can also promote rail vehicle's the operation safety of traveling of receiving electric stability and rail vehicle. The sliding direction through setting up two slip tables 3 has the contained angle with the sliding direction of transition subassembly 4, can make the collecting shoe smoothly pass through the clearance 100a between first contact rail section 1 and the slip table 3 from this to can promote the cooperation stability between collecting shoe and the conductor rail 200.

From this, through the aforesaid setting, can make the cooperation structure between slip table 3 and the fixing base 2 simpler, can also make the operation between slip table 3 and the fixing base 2 more smooth.

In the specific example shown in fig. 2, the slide table 3 may be provided on the left side of the fixed base 2, and a first slide boss 31 may be provided on the right side wall of the slide table 3. One end of the fixing seat 2 can be connected with the first contact rail section 1, and a first sliding groove 21 can be arranged on the left side wall of the fixing seat 2. When the sliding table 3 is assembled with the fixed base 2, the first sliding boss 31 can extend into the first sliding groove 21 and be in sliding fit with the first sliding groove 21, so that the sliding table 3 can slide up and down relative to the fixed base 2. It is of course understood that the fitting structure between the fixed base 2 and the slide table 3 is not limited thereto. For example, the first slide boss 31 extending in the vertical direction may be provided on the fixed base 2, and the first slide groove 21 slidably engaged with the first slide boss 31 may be provided on the slide table 3.

As shown in fig. 5 and 8, in some embodiments of the present invention, one of the fixed base 2 and the sliding table 3 may be provided with a first limiting groove 22, and the other of the fixed base 2 and the sliding table 3 may be provided with a first limiting portion 32 extending into the first limiting groove 22, and the first limiting portion 32 may be configured to slide to cooperate with an end portion of the first limiting groove 22 to limit the moving displacement of the sliding table 3. That is to say, the first limiting groove 22 may be provided on the fixing base 2, the first limiting portion 32 may be provided on the sliding table 3, or the first limiting portion 32 may be provided on the fixing base 2, and the first limiting groove 22 may be provided on the sliding table 3. Wherein, first spacing portion 32 can stretch into first spacing inslot 22 and can reciprocate in first spacing inslot 22, and first spacing groove 22 can inject the displacement of first spacing portion 32, can inject the displacement of the relative fixing base 2 of slip table 3 from this, can prevent slip table 3 and fixing base 2 separation, can promote transition connection device 100's operating stability.

Alternatively, the first position-limiting portion 32 may be formed as a position-limiting pin, and the first position-limiting portion 32 may be matched with the sliding table 3 or the fixing base 2 in an interference fit manner. Therefore, through the arrangement, the design form of the first limiting part 32 can be simpler, and the assembly efficiency of the transition connecting device 100 can be improved.

As shown in fig. 2, 6 and 9, according to some embodiments of the present invention, each sliding table 3 may be provided with a second sliding groove 33, and the transition assembly 4 may be provided with two second sliding bosses 411, each second sliding boss 411 being slidably engaged with the corresponding second sliding groove 33. Specifically, one of the second sliding bosses 411 may be disposed at the front end of the transition assembly 4, the other second sliding boss 411 may be disposed at the rear end of the transition assembly 4, and each second sliding boss 411 may extend into the corresponding second sliding groove 33 and be in sliding fit with the second sliding groove 33. The transition member 4 can move forward and backward relative to the slide table 3 by the sliding fit between the second sliding boss 411 and the second sliding groove 33. Therefore, through the arrangement, the matching structure between the sliding table 3 and the transition assembly 4 is simpler and smoother.

It will be understood, of course, that the mating arrangement between the ramp 3 and the transition assembly 4 is not so limited. For example, the second sliding boss 411 may be provided on the sliding table 3, and two second sliding grooves 33 may be provided on the transition assembly 4, and each second sliding groove 33 may be slidably fitted with the second sliding boss 411 on the corresponding side.

That is, the second limiting groove 34 may be provided on the slide table 3, and the second limiting portion 412 may be provided on the transition unit 4, or the second limiting portion 412 may be provided on the slide table 3, and the second limiting groove 34 may be provided on the transition unit 4. The second limiting portion 412 can extend into the second limiting groove 34 and can be in sliding fit with the second limiting groove 34, and the second limiting groove 34 can limit the moving position of the second limiting portion 412, so that the moving displacement of the transition assembly 4 relative to the sliding table 3 can be limited, the separation of the transition assembly 4 from the sliding table 3 can be prevented, and the structural stability of the transition connection device 100 can be improved.

Alternatively, the second position-limiting portion 412 may also be formed as a position-limiting pin, and the second position-limiting portion 412 may be matched with the sliding table 3 or the transition assembly 4 in an interference fit manner. Therefore, through the arrangement, the design form of the second limiting part 412 can be simpler, and the assembly efficiency of the transition connecting device 100 can be improved.

As shown in fig. 2 and 4, according to some embodiments of the present invention, the end surfaces of the transition member 4 facing the two first contact rail segments 1 may be formed as a first plane 411a, the end surfaces of the two first contact rail segments 1 facing the transition member 4 may be formed as a second plane 1a, the first plane 411a and the second plane 1a may be disposed in parallel, and the first plane 411a may be formed as a slope having an angle with both the length direction and the width direction of the first contact rail segment 1, whereby, by the above arrangement, smooth transition between the two first contact rail segments 1 and the transition member 4 may be achieved, and a collector shoe may be enabled to smoothly pass through the gap 100a between the sliding table 3 and the first contact rail segment 1.

It can be understood that, since the first plane 411a and the second plane 1a are arranged in parallel, the first plane 411a and the second plane 1a may be formed as inclined planes having an angle with both the length direction and the width direction of the first contact rail section 1, and the transition member 4 may be slidably fitted with the slide table 3 to move forward and backward with respect to the slide table 3. When the collector shoe is in sliding fit with the transition connection device 100, the transition assembly 4 can move back and forth to reduce the gap 100a between the sliding table 3 and the first contact rail section 1, and the collector shoe can smoothly pass through the gap between the sliding table 3 and the first contact rail section 1, so that the impact on the collector shoe when passing through the transition connection device 100 can be reduced, the service life of the collector shoe can be prolonged, the phenomenon of arc discharge can be prevented, and the power receiving stability of the railway vehicle can be improved.

Alternatively, the angle between the first and second planes 411a, 1a and the direction of extension of the first contact rail section 1 may be 10 ° -60 °.

Therefore, when the rail vehicle runs, although a tire burst occurs, the sinking amount of the whole vehicle body of the rail vehicle is not more than 25mm, at the moment, the collector shoe can still be in full contact with the transition plate 42, so that the phenomenon that the collector shoe is separated from the conductor rail 200 can be prevented, and the running stability and the power receiving stability of the rail vehicle can be ensured.
