For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to the specific circumstances.

[0044] Reference below Figures 1 to 8 The turnout running device 100 and the turnout 200 according to the embodiment of the present disclosure are described. Figure 1 , 2 5, the turnout 200 may include a translation beam 206; the running device 100 includes a mounting plate 101, a first running wheel 110, a second running wheel 120, a third running wheel 130, a first running guide 10, a second running guide 20 and a driving member 102, and the mounting plate 101 is suitable for connecting with the translation beam 206. The first running wheel 110, the second running wheel 120, and the third running wheel 130 are all rotatably mounted to the mounting plate 101. The first running guide 10 is arranged parallel and spaced from the second running guide 20. The first running wheel 110 and the second running wheel 120 are suitable for running on the first running guide 10, and the third running wheel 130 is suitable for running on the second running guide 20. The first running wheel 110 is transmission-connected with the driving member 102, and the second running wheel 120 and the third running wheel 130 are synchronously transmission-connected with the first running wheel 110.

[0045] In the prior art, the driving member drives the translation beam, and the translation beam drives multiple running wheels to move. The running wheels are all driven wheels and rotate passively. The rotation of the running wheels lags behind the output of the driving force of the driving member, and the rotation of multiple running wheels is not synchronized, which will cause the problem of instantaneous shaking when the turnout is started. In this technical solution, the driving member directly drives the running wheels, and simultaneously synchronizes the transmission connection of multiple running wheels, which solves the problem of instantaneous shaking when the turnout is started and reduces the impact and wear on parts.

[0046] like Figure 2 The axle gear 107 of the first running wheel 110 can be connected to the driving gear 108 of the driving member 102, the first sprocket 105 is installed on the axle of the first running wheel 110, the second sprocket 106 is installed on the axle of the second running wheel 120, and on the same side of the sprocket 105, the first running wheel 110 and the second running wheel 120 are connected to each other by the chain 104, and the second running wheel 120 is connected to the third running wheel 130 by the coupling 103.

[0047] In addition, in some other embodiments, for example, the first running wheel 110 and the driving member 102 realize synchronous transmission through a coupling or a shaft-key-hub; for example, the synchronous transmission connection between the first, second and third running wheels can be realized by a sprocket-chain and / or a gear pair and / or a synchronous pulley and / or a coupling; for example, the driving gear 108 of the driving member 102 simultaneously drives the gears on the axles of the first running wheel 110 and the second running wheel 120 to realize synchronous rotation of the first running wheel 110 and the second running wheel 120.

[0048] like Figure 2-3 The drive member decoupling mechanism 300 may include a sliding assembly 310 and a locking assembly 320. The drive member 102 is slidably connected to the mounting plate 101 through the sliding assembly 310, and the locking assembly 320 is connected to the sliding assembly 310 and mounted on the mounting plate 101, and is used to control the coupling or decoupling between the drive member 102 and the first running wheel 110.

[0049] like Figure 3 The sliding assembly 310 may include a slide groove 311 and a slider 312. The slide groove 311 is connected to the mounting plate 101. The driving member 102 is locked to the slider 312. The slider 312 is slidably connected and embedded in the slide groove 311. Optionally, the sliding assembly 310 may also realize the above sliding function by means of a guide rail-slider or a slide bar-slider.

[0050] Furthermore, the sliding assembly 310 may also include a slide groove limiting plate 313, which is fixed to the end face of the slide groove 311 in the decoupling direction to prevent the slide groove 311 from loosening and shifting during long-term operation, and is also convenient for replacement and reassembly during overhaul.

[0051] like Figure 4 The locking assembly 320 may include a movable portion 330, a fixed portion 340 and a locking member 321. The movable portion 330 includes a screw nut 331 and a coupling locking hole 332. The fixed portion 340 includes a screw 341, a bearing 342 and a crank 343. The bearing 342 is fixed to the fixed portion 340 and is arranged at both ends of the screw 341. The screw 341 is rotatably connected to the bearing 342. The end of the screw 341 away from the slider 312 is provided with a crank 343. When the crank 343 is shaken, the screw 341 rotates, so that the movable portion 330 moves along the screw 341. 41 axially moves, thereby moving the driving member 102 through the slider 312; when the driving member is in the coupling and locking state, the driving gear 108 of the driving member 102 is meshed with the wheel shaft gear 107 of the first running wheel 110, and the locking member 321 is spun into the coupling locking hole 332; when decoupling is required, the locking member 321 is screwed out of the coupling locking hole 332, and the crank 343 is shaken to drive the screw 341 to rotate, so that the movable part 330 drives the driving gear 108 of the driving member 102 to disengage the wheel shaft gear 107 of the first running wheel 110, that is, decoupling is achieved. Optionally, the screw nut can be used as a fixed part, and one end of the screw can be rotatably connected to the slider through a bearing, and drives the slider to move along the axial direction of the screw.

[0052] When a switch failure requires manual operation to switch the switch, it is only necessary to decouple the drive member 102 from the first running wheel 110, manually push the translation beam 206 into place, and then couple and lock the drive member 102 and the first running wheel 110 to quickly restore the passage, reduce the difficulty of maintenance, and increase the speed of maintenance.

[0053] refer to Figure 5 , Figure 6 and Figure 7 The first running wheel 110 and the second running wheel 120 are suitable for rolling on the top surface of the first running guide member 10, and the third running wheel 130 is suitable for rolling on the top surface of the second running guide member 20; the first running wheel 110, the second running wheel 120 and the third running wheel 130 are all double flange wheels, such as Figure 5 In the embodiment shown in the enlarged view, the left flange of the third running wheel 130 is attached to the left end surface of the second running guide 20, and the right flanges of the first running wheel 110 and the second running wheel 120 are attached to the right end surface of the first running guide 10, so as to limit the movement of the running wheels along the length direction of the running guide. Figure 6 In another embodiment, the right flange of the third running wheel 130 is attached to the right end surface of the second running guide 20 , and the left flanges of the first running wheel 110 and the second running wheel 120 are attached to the left end surface of the first running guide 10 .

[0054] In the related art, it is necessary to add a plurality of limiting wheels to limit the movement direction of the running wheel. In this embodiment, the movement direction of the running wheel can be limited only by abutting the existing wheel rim of the running wheel with the end faces of the first and second running guide members. Compared with the existing technology, this solution has streamlined components, a simple structure, and is easy to install.

[0055] The turnout 200 may further include a first load-bearing beam 204 and a second load-bearing beam 205 , and the first running guide member 10 and the second running guide member 20 are suitable for being installed on the first load-bearing beam 204 and the second load-bearing beam 205 , respectively.

[0056] like Figure 7 The running device 100 of the turnout may further include a stabilizing wheel assembly 140 and a stabilizing pad 150. A plurality of stabilizing wheel assemblies 140 and stabilizing pads 150 may be provided according to the number of running wheels. The stabilizing wheel assembly 140 includes a stabilizing wheel 141 and a mounting bracket 142; the upper portion of the mounting bracket 142 is fixedly connected to the mounting plate 101, and the stabilizing wheel 141 is mounted on the lower end of the mounting bracket 142. The stabilizing pad 150 is multi-layered and suitable for being fixed below the upper flange plate of the first load-bearing beam 204. The stabilizing wheel 141 is suitable for abutting against the stabilizing pad 150. The stabilizing pad 150 includes a first stabilizing pad 151 and a second stabilizing pad 152. When the turnout 200 is in the positive position, the stabilizing wheel 141 abuts against the first stabilizing pad 151, and when the turnout is in the reverse position, the stabilizing wheel 141 abuts against the second stabilizing pad 152. The positive and reverse positions are as follows. Figure 8 .

[0057] In the related art, it is necessary to add a gasket between the mounting bracket and the mounting plate to adjust the abutment between the stabilizing wheel and the lower end surface of the running guide. Since there is a height difference in the lower end surface of the running guide within the entire length range, it may be subject to additional resistance during the movement of the running wheel or the abutment surface gap is large when the running wheel is in the locked position, and the width of the lower end surface of the running guide is small, the abutment contact surface is small, and the stabilization effect is not good. In this embodiment, the stabilizing pad is only set when the running wheel is in the locking position of the positioning and reverse position. The abutment contact surface is large, and no additional resistance is generated during the movement of the running wheel. Compared with the solution of setting a gasket in the related art, the stabilization effect is better.

[0058] like Figure 1As shown, the embodiment of the present disclosure further provides a turnout 200, which may include a first fixed beam 201, a second fixed beam 202, a third fixed beam 203, a first load-bearing beam 204, a second load-bearing beam 205, a translation beam 206, a rotating beam 207, and the running device 100 described in the above embodiment, wherein the translation beam 206 and the rotating beam 207 are arranged between the first fixed beam 201 and the second fixed beam 202 to switch different driving channels, one end of the rotating beam 207 is rotatably connected to the third fixed beam 203, and the translation beam 206 is rotatably connected to the other end of the rotating beam 207; the first load-bearing beam 204 and the second load-bearing beam 205 are fixed between the first fixed beam 201 and the second fixed beam 203. The translation beam 206 is slidably connected to the running device 100 and can slide along the length direction of the translation beam.

[0059] In the present disclosure, the first load-bearing beam 204 and the second load-bearing beam 205 are arranged at intervals, which is suitable for the elevated installation of the turnout, and is beneficial to reducing the load on the elevated pier foundation; when the turnout is set on the ground, the first load-bearing beam and the second load-bearing beam can also be combined, or the first and second load-bearing beams can be replaced by a turnout boss or platform to facilitate installation and reduce costs.
