[0023] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0024] Example 1

[0025] like Figure 1 As shown, this embodiment proposes a bogie, which includes:

[0026] Framework 1;

[0027] A steering mechanism, rotatably disposed at the front end and / or rear end of the frame 1, is used to contact the steering baffle 8 in the track turnout area, so that the rail vehicle travels along the extension direction of the steering baffle 8.

[0028] The controller is used to receive the turnout signal from the trackside equipment, obtain the running direction based on the turnout signal, and control the steering mechanism to rotate to a preset position corresponding to the running direction. The preset position is the contact position between the steering mechanism and the steering baffle 8 in the track turnout area in the running direction.

[0029] Specifically, the basic structure of the bogie frame 1 in this embodiment is no different from that of a conventional bogie. A steering mechanism is provided on the frame 1. The steering mechanism can contact the steering baffle 8 provided in the track turnout area and cause the rail vehicle to travel along the extension direction of the steering baffle 8 to the target track. The steering mechanism can be provided at the front end or rear end of the frame 1, or at both ends; this embodiment does not make any special limitations. Of course, if the steering mechanism is provided at both the front and rear ends of the frame 1, the consistency of the operation of the front and rear steering mechanisms must be ensured.

[0030] In the embodiment, the steering mechanism can be controlled by a controller. The controller can be arranged inside the frame 1 and control the steering mechanism through electrical connection.

[0031] Specifically, in the embodiment, the steering mechanism is composed of a motor, a rotating rod 4, a horizontal rod 5, a vertical rod 6 and a steering wheel 7. The motor is fixed on the frame 1 and electrically connected with the controller. The controller can control the working state of the motor. The output shaft of the motor is connected with one end of the rotating rod 4, so that the controller can make the rotating rod 4 rotate through the motor. The horizontal rod 5 is fixed at the end of the rotating rod 4 and arranged parallel to the track surface. The vertical rod 6 is fixed at the end of the horizontal rod 5 and perpendicular to the horizontal rod 5. The steering wheel 7 is fixed at the end of the vertical rod 6 and the rotating surface of the steering wheel 7 is parallel to the track surface.

[0032] In the embodiment, the controller can receive the turnout signal of the trackside equipment, and then obtain the running direction in front of the track vehicle, i.e. the target track into which the track vehicle will enter, through the turnout signal. After obtaining the running direction, the controller controls the motor and then drives the rotating rod 4, the horizontal rod 5 and the vertical rod 6 to act in sequence, so that the steering wheel 7 rotates to a preset position corresponding to the running direction, and when the steering wheel 7 reaches the preset position, the track vehicle can drive along the extension direction of the steering baffle 8 into the target track under the contact action of the steering wheel 7 and the steering baffle 8 in the track turnout area.

[0033] In addition, in addition to the steering mechanism proposed in the embodiment achieving contact with the steering baffle 8 through rotating structure, it can also be achieved in the way of lifting. That is, the controller can be connected with a lifting motor, and the lifting motor is connected with two steering wheels 7 through a lifting mechanism, which can be realized by gear transmission. After the two steering wheels 7 are lowered, they can respectively contact two different positions of the steering baffle 8. When the controller obtains the running direction according to the turnout signal, it can lift one steering wheel 7 corresponding to the running direction, so that the steering wheel 7 contacts the steering baffle 8 and then drives along the extension direction of the steering baffle 8.

[0034] Further, walking wheels 2 are arranged at the four corners of the frame 1, which can drive the track vehicle to run on the track beam under the driving of the internal control system of the track vehicle. Guide wheels 3 are also arranged outside the frame 1. The guide wheels 3 can contact and rotate on the inner side of the side wall of the track beam, which can not only play a guiding role, but also play a stabilizing role in the running process of the track vehicle to prevent the track vehicle from shaking in the running process.

[0035] Embodiment 2

[0036] The embodiment proposes a track vehicle, which comprises a bogie. The structure of the bogie can refer to the content described in embodiment 1, which will not be described here again.

[0037] Example 3

[0038] like Figures 2 to 5 As shown, this embodiment proposes a track, which consists of a main track segment 9, a first sub-track segment 10, and a second sub-track segment 11. The main track segment 9, the first sub-track segment 10, and the second sub-track segment 11 are connected in a Y-shape, as shown... Figure 3 As shown, a turnout area is formed at the connection of the main track section 9, the first sub-track section 10, and the second sub-track section 11. After the rail vehicle travels on the main track to the turnout area, it can change lanes by cooperating with the steering mechanism on the rail vehicle through the steering baffle 8 set in the turnout area.

[0039] Specifically, the track in this embodiment can be used in conjunction with the rail vehicle proposed in Embodiment 2. The rail vehicle first runs normally within the main track section 9, then determines its direction of travel before entering the turnout area, and subsequently controls the steering mechanism to operate before entering the turnout area. A steering baffle 8 is provided in the turnout area of ​​this track, specifically divided into a first steering baffle 10-4 and a second steering baffle 11-4, as shown below. Figure 4 As shown. The first steering baffle 10-4 extends to the first sub-track section 10, and the second steering baffle 11-4 extends to the second sub-track section 11. When the controller obtains the running direction based on the turnout signal from the trackside equipment, the controller can control the steering mechanism to rotate to the side of the first steering baffle 10-4 or the side of the second steering baffle 11-4 to achieve a lane change. For example, if the running direction is to travel to the first sub-track section 10, the controller will control the steering mechanism to rotate to a position where the steering wheel 7 contacts the first steering baffle 10-4, thereby allowing the rail vehicle to travel to the first sub-track section 10 under the contact between the steering wheel 7 and the first steering baffle 10-4. If the running direction is to travel to the second sub-track section 11, the controller will control the steering mechanism to rotate to a position where the steering wheel 7 contacts the second steering baffle.

[0040] In actual rail vehicle operation, the running direction of the first sub-track segment 10 or the second sub-track segment 11 is often different from that of the main track segment 9, resulting in a certain curvature. To better achieve the steering function of the steering mechanism, this embodiment sets the contact position between the steering mechanism and the steering baffle 8 according to the turning direction of the first sub-track segment 10 or the second sub-track segment 11.

[0041] If the running direction is to enter the second sub-track section 11, and the second sub-track section 11 is a right turn, this embodiment can rotate the steering mechanism to a position close to the right side of the second steering baffle 11-4, so that the steering wheel 7 can contact the right side wall of the second steering baffle 11-4, such as... Figure 5As shown. In this way, when the rail vehicle is moving to turn right in the second sub-track section 11, the steering wheel 7 can maintain contact and extrusion between the second steering baffle 11-4 in real time, which fully guarantees the steering effect of the rail vehicle when driving in the second sub-track section 11. Similarly, if the running direction is to enter the second sub-track section 11, and the second sub-track section 11 is to turn left, the steering wheel 7 needs to be in contact with the left side wall of the second steering baffle 11-4, as shown. Figure 2

[0042] In order to make the contact between the steering mechanism and the first steering baffle 10-4 or the second steering baffle 11-4 more smooth, and to minimize the steering range of the steering mechanism, the end of the first steering baffle 10-4 and the second steering baffle 11-4 can be extended into the main track section 9 compared to a point. In this way, the width of the steering baffle 8 can be further reduced, the steering range of the steering mechanism can be reduced, and more advance can be provided for the rotation of the steering mechanism before the rail vehicle enters the turnout area, improving safety.

[0043] In addition, in the present embodiment, the setting position and installation form of the first steering baffle 10-4 and the second steering baffle 11-4 are also flexible. One of the optional ways is to directly use a long strip-shaped metal plate structure, and the first steering baffle 10-4 and the second steering baffle 11-4 are arranged in a herringbone shape in the middle area of the track. Another optional way is to use a buckle form, when the steering wheel 7 contacts the steering baffle 8, the steering wheel 7 is located below the steering baffle 8 and contacts the downwardly bent side wall of the steering baffle 8. The above two ways can be used flexibly according to the site environment, and the present embodiment does not make special limitations.

[0044] In the track proposed in the present embodiment, the main body structure of the main track section 9, the first sub-track section 10 and the second sub-track section 11 is a U-shaped structure, which is specifically composed of two track beams with an L-shaped cross section and a sleeper beam connected between the two track beams. The rail vehicle is placed in the area between the two track beams and the sleeper beam. The running wheel 2 of the rail vehicle is located above the horizontal plane of the track beam, and the guide wheel 3 rotates on the vertical plane of the track beam. However, the L-shaped track beam will hinder the normal lane change of the rail vehicle at the turnout area, therefore, the structure of the first sub-track section 10 and the second sub-track section 11 in the turnout area is adjusted in the present embodiment.

[0045] ​Specifically, in the embodiment, the first sub-track section 10 includes a first track beam 10-1, a second track beam 10-2, and a first sleeper beam 10-3. The first track beam 10-1 and the second track beam 10-2 are oppositely arranged, and the first track beam 10-1 and the second track beam 10-2 are connected by the first sleeper beam 10-3. A section of the second track beam 10-2 in the turnout area has a rectangular cross section. Correspondingly, the second sub-track section 11 includes a third track beam 11-1, a fourth track beam 11-2, and a second sleeper beam 11-3. The third track beam 11-1 and the fourth track beam 11-2 are oppositely arranged, and the third track beam 11-1 and the fourth track beam 11-2 are connected by the second sleeper beam 11-3. A section of the third track beam 11-1 in the turnout area has a rectangular cross section.

[0046] In the embodiment, the second track beam 10-2 and the third track beam 11-1 of the first sub-track section 10 and the second sub-track section 11 in the turnout area are crossed, and the vertical surface is cancelled, so that the surface of the second track beam 10-2 and the third track beam 11-1 is smoother, and the normal lane changing of the rail vehicle in the turnout area is not affected.

[0047] Further, in the embodiment, the position where the turning mechanism is actuated is before the turnout area, and therefore, the turning baffle 8 needs to pass through the main track section 9, the turnout area, and the first sub-track section 10 or the second sub-track section 11, so as to ensure the turning and lane changing of the rail vehicle. In this way, the second track beam 10-2 of the first sub-track section 10 and the third track beam 11-1 of the second sub-track section 11 will be crossed with the second turning baffle 11-4 and the first turning baffle 10-4, thereby affecting the normal operation of the rail vehicle. In view of this, in the embodiment, the second track beam 10-2 is disconnected at the intersection of the second turning baffle 11-4 and the second track beam 10-2 in the turnout area. Correspondingly, the third track beam 11-1 is disconnected at the intersection of the first turning baffle 10-4 and the third track beam 11-1 in the turnout area. In this way, the rail vehicle can smoothly drive into the second sub-track section 11 or the first sub-track section 10 through the disconnected position of the second track beam 10-2 or the third track beam 11-1 during the operation in the turnout area.

[0048] The embodiment can optimize the traditional movable turnout into a fixed turnout, and reduce the manufacturing, construction, and maintenance costs of the turnout area. Meanwhile, the fixed turnout does not need to consider the moving space, and does not involve electrical equipment such as motors, transmissions, and synchronization devices, thereby saving space and improving safety.
