Description

Technical Field

[0001] The present invention relates to the technical field of turnouts, and in particular, to a turnout rail moving and fixing device and method. Background Art

[0002] The suspended monorail is a type of monorail. Its characteristic is that it uses only one track, rather than the two balanced tracks of a traditional railway. Similar to urban rail transit systems, monorails are mainly used in densely populated urban areas to carry passengers. There are also monorails built in amusement parks specifically for carrying tourists. Monorails are mainly divided into two categories according to the running mode and structure - suspended monorails and straddle monorails. The trains of suspended monorails (also known as sky trains) are suspended below the tracks.

[0003] A turnout is a track connection device that enables locomotives and rolling stocks to switch from one track to another. Existing turnouts generally use a drive motor or other drive devices to swing the rails to achieve train track switching. However, this results in a relatively complex turnout structure and a high manufacturing cost. Summary of the Invention

The positions of the first movable grooves and the second movable grooves correspond one by one and are in a cross shape;

[0010] The rail control part is inserted at the intersection of the first movable slot and the second movable slot. When the movable beam swings relative to the fixed beam, the movement track of the rail control part controlled by the first movable slot and the second movable slot;

[0012] The driving and fixing device includes a guiding part, a sliding part, and a driving part for driving the sliding part to slide along the guiding part. The free end of the movable beam is fixed to the sliding part;

[0013] It further includes limiting blocks arranged at both ends of the guiding part, and the limiting blocks are used to limit the swinging angle of the free end of the movable beam.

[0036] Embodiment 1:

[0037] Please refer to Figures 1 to 7 , a turnout rail moving and fixing device, including a rail and a track beam. A fixing member for connecting the rail and the track beam is arranged at the bottom of the rail. The track beam includes a movable beam 2 and a fixed beam 1 for laying the rail. The movable beam 2 is hinged to the fixed beam 1, and a driving and fixing device for driving the movable beam 2 to swing relative to the fixed beam 1 is arranged at the free end of the movable beam 2; a rail control part is arranged between the movable beam and the fixing member and between the fixed beam and the fixing member. The rail control part is used to control the elastic bending of the rail at the hinge joint of the movable beam 2 and the fixed beam 1 and fix the rail.

[0038] In order to simplify the turnout structure and reduce the manufacturing cost, in this technical solution, the track beam is set as a movable beam 2 and a fixed beam 1. Fixed rails are laid on the movable beam 2 and the fixed beam 1, and an elastically bendable movable rail 3 is laid at the hinge joint between the movable beam 2 and the fixed beam 1. The elastic bending of the movable rail 3 means that one end of the movable rail 3 is fixed to the fixed beam 1, and one end of the movable rail 3 on the movable beam 2 is a free end, and the free end swings left and right in the horizontal plane. The maximum swing angle α of the free end of the movable rail 3 is 8°. A driving and fixing device is arranged at the free end of the movable beam 2, and the free end of the movable beam 2 is driven by the driving and fixing device to swing left and right in the horizontal plane. When the movable beam 2 swings to the preset side position, the movable beam 2 and the fixed beam 1 form a broken line shape. Since the movable rail 3 is an elastic part, the movable rail 3 elastically bends into an arc shape at the turning point between the movable beam 2 and the fixed beam 1, and the movable rail 3 uses a rail control part to control the completion degree of the movable rail 3 and fix the movable rail 3, ensuring that the gauge between two parallel movable rails 3 is within the specified range. The rail control part can adopt an adaptive control structure or a mechanical clamping and positioning structure. Compared with the prior art, in this technical solution, the elastic bending of the rail is realized through the swing of the beam, and the bending parameters of the rail are controlled by the rail control part, simplifying the turnout structure and reducing the manufacturing cost.

[0039] In this embodiment, the fixing member for connecting the rail and the track beam can be a rail fastener or other structures that can realize the connection between the rail and the track beam.

[0040] In this embodiment, the rail control part adopts an adaptive control structure. The following is the specific structure:

[0041] In this embodiment, one end of the movable beam 2 is provided with a plug-in part, the plug-in part is inserted into the fixed beam 1, and the plug-in part is hinged to the fixed beam 1.

[0042] In order to connect the movable beam 2 and the fixed beam 1 and enable the movable beam 2 to swing in the horizontal plane, the movable beam 2 and the fixed beam 1 are hinged. In order to realize the adaptive control structure, in this technical solution, the hinged end of the movable beam 2 and the fixed beam 1 is set as a plug-in structure. The plug-in structure here means that one end of the movable beam 2 is inserted into the fixed beam 1, or a section extends from the track installation surfaces of the movable beam 2 and the fixed beam 1 respectively, and the extended section of the movable beam 2 and the extended section of the fixed beam 1 are overlapped.

[0043] In this embodiment, the plug-in part of the movable beam 2 is provided with a plurality of second movable grooves 21 for controlling the displacement of the rail relative to the movable beam 2, and the fixed beam 1 is provided with a plurality of first movable grooves 11 for controlling the displacement of the rail relative to the fixed beam 1. The positions of the first movable grooves 11 and the second movable grooves 21 correspond one by one and are in a cross shape.

[0044] In order to control the elastic bending of the movable rail 3 and ensure that the track gauge is within the specified range after the movable rail 3 is elastically bent, the technical solution provides a plurality of second movable grooves 21 on the movable beam 2 and a plurality of first movable grooves 11 on the fixed beam 1. Since the plug-in parts of the movable beam 2 and the fixed beam 1 overlap, and the positions of the first movable grooves 11 and the second movable grooves 21 correspond one to one, the lengths, shapes and angles of the first movable grooves 11 and the second movable grooves 21 are obtained by calculation. After the calculation, the first movable grooves 11 and the second movable grooves 21 at the corresponding positions are in a cross shape.

[0045] The calculation of the length, shape and angle of the first movable groove 11 or the second movable groove 21 is essentially the calculation of the moving track of the movable rail 3 relative to the fixed beam 1 or the movable beam 2 during the bending process. The calculation of the moving track of the movable rail 3 relative to the fixed beam 1 during the bending process is used as an example to illustrate, that is, the calculation of the first movable groove 11:

[0046] Since the movable rail 3 is composed of two parallel left and right single rails, during the elastic bending process of the movable rail 3, the bending actions of the two left and right single rails are consistent. Therefore, the following calculation takes the right rail as an example to establish a plane rectangular coordinate system O1. One end of the right rail is set as the top end and the other end is the moving end. The right rail can be regarded as a cantilever beam. Since the movable beam 2 swings left and right in the horizontal plane, it is assumed that a horizontal rightward moment M is applied to the moving end of the right rail. In the plane rectangular coordinate system, it is a moment M parallel to the X1 axis and along the positive direction of the X1 axis. When there is no moment M acting on the moving end of the right rail, the right rail is straight and parallel to the Y1 axis. When the moving end of the right rail is acted upon by the moment M, the right rail is bent. According to actual applications, the bending angle of the rail at the moving end of the right rail is small, so the offset of the moving end of the right rail only considers the offset along the X1 axis, and ignores the offset of the moving end of the right rail along the Y1 axis.

[0047] Assuming that the offset of the moving end of the right rail is d, take three points A1, B1, and C1 in the plane rectangular coordinate system O1. The coordinates of points A1, B1, and C1 are expressed as , , ,

[0048] When the right rail is subjected to the action of the moment M, it bends elastically and establishes the plane rectangular coordinate system O2. After bending, the line connecting the moving end and the fixed end of the right rail rotates α degrees relative to the straight right rail. The center of rotation is the fixed end of the right rail. That is, the plane rectangular coordinate system O2 rotates α degrees relative to the plane rectangular coordinate system O1 with the origin as the center. The rotation angle is , then in the plane rectangular coordinate system O2, the coordinates of the corresponding points A2, B2, and C2 on the right track are expressed as , and ,

[0049] Since the offset d of the moving end of the right rail has a range, based on the coordinates of points A2, B2, and C2 and in combination with the offset d, the movement trajectories of points A, B, and C on the right rail can be calculated. The corresponding first movable slot 11 is based on the calculated movement trajectories. The calculation principle of the second movable slot 21 is the same as above.

[0050] The rail control part is inserted at the intersection of the first movable slot 11 and the second movable slot 21. When the movable beam 2 swings relative to the fixed beam 1, the movement trajectories of the rail control parts controlled by the first movable slot 11 and the second movable slot 21.

[0051] According to the first movable slot 11 and the second movable slot 21 obtained from the foregoing calculation, since the first movable slot 11 and the second movable slot 21 intersect, there is an intersection point between the first movable slot 11 and the second movable slot 21. This intersection point is the preset trajectory for the bending of the movable rail 3. The rail control part is fixed at the intersection point, and the bending of the movable rail 3 is controlled through the rail control part. The rail control part can be a pin shaft, a slider that can slide in the first movable slot 11 and the second movable slot 21, or other structures that can slide in the first movable slot 11 and the second movable slot 21. In this embodiment, the rail control part is a pin shaft 5. After the movable beam 2 swings in place, the movable beam 2 is fixed. At this time, the intersecting first movable slot 11 and second movable slot 21 limit the free movement of the pin shaft 5 in the horizontal plane, which ensures that the movable rail elastically bends into a preset shape and ensures that the gauge of the two movable rails is always within the set range.

[0052] In this embodiment, the rail control part includes a pin shaft 5, and one end of the pin shaft 5 is fixed to a fixing member.

[0053] In this embodiment, the driving and fixing device includes a guiding part, a sliding part, and a driving part for driving the sliding part to slide along the guiding part. The free end of the movable beam 2 is fixed to the sliding part.

[0054] In order to drive the free end of the movable beam 2 to swing left and right in the horizontal plane, this technical solution is provided with a driving part to drive the free end of the movable beam 2, and a support frame for installing the driving component is also configured. The driving part can be a cylinder, a hydraulic cylinder, a motor, or other structures that can push the free end of the movable beam 2 to move. The guiding part can be a chute or a rail, and the sliding part can be a movable structure with pulleys. The sliding part is fixed to the free end of the movable beam 2, and the pulleys roll along the chute or the rail.

[0055] It further includes limit blocks disposed at both ends of the guiding portion, and the limit blocks are used to limit the swing angle of the free end of the movable beam 2.

[0056] Since the elastic bending of the movable rail is also limited, in order to ensure that the elastic bending of the movable rail is within a reasonable range and to prevent the swing of the movable beam 2 from exceeding the set range when the driving portion fails, resulting in irreversible plastic bending of the movable rail, this technical solution sets limit blocks at both ends of the guiding portion to ensure that the elastic bending of the movable rail is within a reasonable range.

[0057] In this embodiment, the guiding portion is configured as an arc-shaped groove, and the arc-shaped groove is centered on the hinge point of the movable beam 2 and the fixed beam 1.

[0058] In this embodiment, the guiding portion is configured as an arc-shaped rail.

[0059] In this embodiment, the fixing member is configured as a rail fastener 4, and balls or rollers 41 are arranged on the contact wall of the rail fastener 4 with the rail, and the balls or rollers 41 are in contact with the rail.

[0060] The rail fastener is used to limit the movable rail 3 to move only along the length direction of the rail. When the movable rail elastically bends, the bent section of the movable rail will rub against the corresponding rail fastener 4. In order to avoid wear of the movable rail 3 or the rail fastener 4, this technical solution sets balls or rollers 41 on the rail fastener 4. The balls or rollers are in contact with the movable rail 3. When the movable rail 3 bends, the balls or rollers 41 can prevent the movable rail 3 from directly rubbing against the rail fastener 4.

[0061] Embodiment 2:

[0062] A method for moving a turnout rail uses a turnout rail moving and fixing device. When the track needs to be changed, the driving and fixing device is started. The driving and fixing device drives the free end of the movable beam 2 to swing around the hinge point of the insertion portion of the movable beam 2 and the fixed beam 1, so that the free end of the movable beam 2 is aligned with the target track. The first movable groove 11 and the second movable groove 21 control the movement of the pin shaft, and the pin shaft drives the rail to elastically bend.

[0063] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
